One monkey moves closer; another shifts along a branch. Was that a welcome, a disagreement or simply a better place to sit? Primate behaviour vocabulary helps you describe the action before deciding what it means. This guide teaches 100 English words and terms for movement, feeding, communication, social relationships and the evidence needed to explain them.
Equatorial Guinea provides a valuable setting through Bioko Island and its documented primate research. Drexel University’s accounts describe the Bioko Biodiversity Protection Program’s partnership with the National University of Equatorial Guinea and research involving the island’s monkeys. We use that specific context—not an assumption that all the country’s wildlife or communities are alike—to build more precise scientific English. Start with one short, institutionally published description or permitted video, choose ten connected words and separate what is visible from what is inferred.
“Top 100” means a curated learning selection, not a statistical frequency ranking. Behaviour is the British spelling; behavior is common in American English. The terms are general English and established scientific vocabulary, not a local-language phrasebook. Every observation scene, coded record and conversation below is fictional. Comparative concepts are not claims that every Bioko species performs every behaviour. No wildlife approach, playback, feeding, habituation or field-access activity is required or recommended.
Choose the behaviour question you want to understand
Follow an action through space, a feeding decision or a social exchange. Then ask how a researcher would distinguish the possible explanations.
Before the list: can you replace a motive with an action?
Try revising “The monkey was rude.” What happened? Perhaps one individual moved away after another approached; perhaps an observer saw an open mouth but missed the preceding events. Rude is a human social judgement, not a reproducible description. Begin with approach, retreat, posture and sequence. A warmer understanding of animals can grow from greater precision rather than a more elaborate invented inner monologue.
Now consider “No calls were recorded, so the group was silent all day.” How long was the recording? Was the relevant animal visible or audible? Did the equipment capture the frequencies of interest? An absence in a particular record is not automatically an absence across a whole day. If that distinction is unstable, begin with the recording terms in group 9.
Finally, explain the difference between a monkey and an ape without using size as the rule. If the biological categories are uncertain, repair those first. If the categories are secure but the learner struggles with English wording, an oral explanation in a familiar language followed by a supported English sentence may reveal the real need. Diagnose the connection, not the learner’s intelligence from one hesitant answer.

Primate is a broad biological category that includes humans. This article’s country context centres on non-human primate research, especially monkeys on Bioko. A general term should not erase the animal’s actual identity.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 1 | behaviour | The actions and responses of an organism; usually uncountable in general English, with behaviours used for distinct patterns in scientific writing. | primate behaviour | The behaviour description began with a visible action rather than a personality label. |
| 2 | ethology | The scientific study of animal behaviour; specialist subject noun. | comparative ethology | Ethology gave the learner a way to ask how an action was studied. |
| 3 | primate | A mammal within the order that includes monkeys, apes, lemurs and related groups. | non-human primate | The primate record specified its subject rather than treating the order as one species. |
| 4 | monkey | A common name for particular non-ape primate groups; not a scientific synonym for every primate. | monkey behaviour | The monkey example was not relabelled as an ape because it looked large. |
| 5 | ape | A member of the primate group including gibbons, great apes and humans; not simply a large monkey. | non-human ape | The ape comparison was explicitly comparative, not a claim about Bioko’s monkey species. |
| 6 | conspecific | An individual belonging to the same species; noun or adjective in scientific use. | conspecific interaction | The conspecific interaction involved two animals of the same identified species. |
| 7 | arboreal | Associated with living or activity in trees; the degree and context vary. | arboreal locomotion | The arboreal account described movement above ground without assuming every activity occurred there. |
| 8 | terrestrial | Associated with land or, in this behavioural contrast, ground-level activity. | terrestrial movement | The terrestrial movement record concerned the ground rather than an entire planet. |
| 9 | diurnal | Characteristically active during daylight; not a claim of uninterrupted activity all day. | diurnal activity | The diurnal description still allowed periods of resting. |
| 10 | gregarious | Tending to associate or live with others; a behavioural descriptor, not proof of identical group structures. | gregarious species | The gregarious label did not tell us every individual’s relationship. |
Drexel’s Bioko research account supplies the geographical and institutional setting. This list does not transfer every primate example from a general textbook onto Bioko or infer an island species list from mainland wildlife.
Movement words answer how an animal changes position. A leap, a climb and a walk are not interchangeable, even when they end at the same branch.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 11 | locomotion | Movement that changes an organism’s position from one place to another. | locomotor behaviour | The locomotion record distinguished travel from an animal adjusting its posture. |
| 12 | climb | To move up, down or across a support using limbs or other gripping structures. | climb a trunk | The fictional monkey climbed the trunk before moving onto a branch. |
| 13 | ascend | To move upwards; more formal than go up and not restricted to climbing. | ascend a support | The observer used ascend to state direction without adding a motive. |
| 14 | descend | To move downwards; direction alone does not identify the precise locomotor method. | descend towards the ground | The animal descended towards the ground in the illustrated sequence. |
| 15 | leap | To propel the body across a gap, losing contact with the initial support. | leap between supports | The leap connected two branches in the classroom drawing. |
| 16 | landing | The contact and stabilisation at the end of a leap or airborne movement. | controlled landing | The landing was recorded separately from the take-off in the slow illustration. |
| 17 | quadrupedal | Using four limbs for support and locomotion in the behaviour described. | quadrupedal walking | The quadrupedal walking description concerned one movement mode, not every possible posture. |
| 18 | bipedal | Using two limbs for support or locomotion in the specified context. | brief bipedal stance | The bipedal stance was brief and did not establish habitual two-legged travel. |
| 19 | grasp | To take and hold something with a hand, foot or other suitable structure. | grasp a branch | The animal grasped the branch before shifting its weight. |
| 20 | balance | To maintain or regain a stable body position relative to support and movement. | maintain balance | The balance adjustment occurred before the next step in the invented sequence. |
Do not infer a species’ whole locomotor repertoire from one image. These are descriptive tools. A general comparison involving an ape or a primate from another continent must remain clearly labelled as a comparison.
An animal can remain in one place while changing its body arrangement, head direction or visible attention. A good record gives those actions room rather than classifying everything as moving or not moving.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 21 | posture | The arrangement or position of the body and its parts. | resting posture | The posture changed while the animal remained on the same support. |
| 22 | perch | A support on which an animal rests or sits; also a verb. | narrow perch | The perch was described by position without assuming ownership. |
| 23 | crouch | To lower the body with bent limbs; the function depends on context. | crouched posture | The crouch was visible, but the observer did not call it fear without further evidence. |
| 24 | recline | To rest with the body leaning or lying back; a descriptive verb. | recline on a support | The animal reclined in the fictional sketch while its head remained raised. |
| 25 | rest | To remain relatively inactive under a defined behavioural category; not identical to sleep. | resting bout | The rest category did not establish that the animal was asleep. |
| 26 | sleep | A physiological and behavioural state requiring appropriate criteria; closed eyes alone may be insufficient. | sleeping posture | The sleeping posture was labelled cautiously because the image lacked further evidence. |
| 27 | vigilance | Attention directed towards detecting relevant events or potential threats, operationally defined in a study. | vigilance behaviour | The vigilance category used head and gaze criteria specified for the exercise. |
| 28 | scan | To look across an area through a sequence of directed looks; distinguish this action from scan sampling. | scan the surroundings | The monkey scanned the surroundings in the fictional animation. |
| 29 | orient | To turn or position the body or a body part relative to something. | orient towards a sound | The individual oriented towards the sound source in the invented record. |
| 30 | concealment | Being hidden or difficult to detect; concealment does not prove a deliberate intention to hide. | partial concealment | The concealment prevented the observer from classifying the next action. |
Describe head movement when that is what the material shows. Calling it vigilance or sleep can require an operational definition and evidence unavailable in a brief public image.
WORD GROUP 4 OF 10
31–40. Food behaviour includes searching, selecting and handling
Eating is not the entire feeding story. An animal may search, inspect or handle an item before anything is swallowed. Keep the item, action and longer-term diet separate.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 31 | forage | To search for or obtain food; a feeding-related action rather than a complete diet description. | forage for food | The fictional individual foraged among leaves before selecting an item. |
| 32 | feeding | Taking in or consuming food under the study’s definition; not always identical to searching for it. | feeding event | The feeding event began after the search phase in the teaching record. |
| 33 | frugivorous | Feeding substantially or mainly on fruit; the precise dietary classification needs evidence. | frugivorous diet | The frugivorous description did not claim that every mouthful was fruit. |
| 34 | folivorous | Feeding substantially or mainly on leaves; an ecological adjective. | folivorous feeding strategy | The folivorous strategy was discussed separately from an isolated leaf-eating event. |
| 35 | insectivorous | Feeding substantially or mainly on insects; not a claim that other foods are impossible. | insectivorous diet | The insectivorous label required more than the sight of one insect being eaten. |
| 36 | selectivity | Non-random choice among available options under stated conditions. | food selectivity | The selectivity question compared what was chosen with what was available. |
| 37 | handling | Manipulation of a food item before or during consumption. | food-handling behaviour | The handling record distinguished turning an item from swallowing it. |
| 38 | chew | To break down food through repeated jaw movements; the exact pattern depends on anatomy. | chew a food item | The observer saw the animal chew but could not identify the food. |
| 39 | swallow | To move material from the mouth towards the digestive tract; visibility and evidence matter. | swallow a mouthful | The fictional scene showed a swallow after the handling phase. |
| 40 | seed dispersal | Movement of seeds away from their source, sometimes mediated by animals; the specific mechanism requires evidence. | primate-mediated seed dispersal | The seed dispersal explanation connected a feeding relationship with a possible ecological effect. |
Drexel’s 2016 research account discusses the ecological importance of primates as seed dispersers. It does not turn every feeding event into successful dispersal or establish the present status of each population.
A social interaction has more than one participant. “There was grooming” is useful; “A groomed B, then B moved away” preserves a richer sequence without inventing a friendship score.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 41 | approach | Movement reducing distance to another individual, under a study’s stated criteria. | social approach | The approach ended beside another animal in the fictional record. |
| 42 | retreat | Movement away from another individual or event; a protocol may specify its timing and distance. | retreat after approach | The retreat followed the approach, but its cause remained a question. |
| 43 | proximity | Closeness in space under a defined distance criterion. | close proximity | The proximity record used a stated threshold rather than “quite near”. |
| 44 | contact | Physical touching between individuals or between an animal and another object. | physical contact | The contact was recorded without assuming its social function. |
| 45 | allogrooming | Grooming another individual’s body surface, often through manual or oral actions; specialist term. | allogrooming bout | The allogrooming bout had an identified initiator and recipient. |
| 46 | autogrooming | Grooming one’s own body surface; distinguish it from grooming another individual. | autogrooming sequence | The autogrooming sequence did not involve a social partner. |
| 47 | huddle | To remain in close bodily association, often with contact; describe participants and context. | social huddle | The huddle in the drawing included three visible individuals. |
| 48 | embrace | To hold another individual with the limbs; the social interpretation needs context. | brief embrace | The embrace was described as a movement rather than a human promise of affection. |
| 49 | initiator | The participant that begins a defined interaction. | interaction initiator | The initiator changed when the second grooming event began. |
| 50 | recipient | The individual towards whom a defined action is directed or who receives it. | grooming recipient | The recipient remained still during the invented grooming record. |
University of Wisconsin–Madison classroom material illustrates the importance of defined approach, retreat and grooming categories. The thresholds and species used there are not a universal coding scheme for Bioko.
Communication is not a miniature human conversation with missing subtitles. Describe the channel and the observable response, then consult the relevant species-specific research before assigning a message.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 51 | signal | An action or feature functioning in communication between organisms; not every detectable cue is necessarily a signal. | social signal | The signal interpretation required evidence about communication, not detectability alone. |
| 52 | cue | Information available to an observer or receiver that need not have evolved or been produced as a communicative signal. | auditory cue | The cue revealed movement without necessarily being a message to another animal. |
| 53 | vocalisation | A sound produced by an animal’s vocal apparatus; vocalization is common US spelling. | primate vocalisation | The vocalisation was described without translating it into an invented sentence. |
| 54 | contact call | A call associated with maintaining contact or information about group members’ whereabouts in the relevant research. | group contact call | The contact call label came from the source rather than the learner’s guess. |
| 55 | alarm call | A vocal signal associated with a potential threat under a species-specific interpretation. | alarm-call response | The alarm call example did not specify a predator without evidence. |
| 56 | gesture | A bodily movement used communicatively under the relevant behavioural criteria. | communicative gesture | The gesture claim required more than noticing that a hand moved. |
| 57 | facial expression | An arrangement or movement of facial features; its meaning depends on species and context. | primate facial expression | The facial expression was not automatically named a human smile. |
| 58 | display | A conspicuous behavioural or physical presentation involved in communication under a stated interpretation. | social display | The display was described before its possible function was discussed. |
| 59 | tactile | Relating to touch; a communication-channel adjective. | tactile communication | The tactile communication example involved physical contact rather than a call. |
| 60 | olfactory | Relating to smell or chemical detection; not directly established by a silent image. | olfactory information | The olfactory information question required evidence beyond the video’s visual record. |
Never play calls to wild animals to create a classroom response. Public institutional material or a fictional record is sufficient. Quiet in a recording may reflect the method, conditions or an animal’s behaviour; it is not a universal conclusion about communication.
WORD GROUP 7 OF 10
61–70. Social relationships need patterns, not personality verdicts
A single encounter does not establish a lasting relationship. Social terms become meaningful through repeated interactions, defined comparisons and the right timescale.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 61 | affiliation | Social association and interactions characterised as positive or relationship-maintaining under defined criteria. | affiliative interaction | The affiliation account drew on a pattern rather than one nearby seat. |
| 62 | agonistic | Relating to conflict interactions, including threats, attacks, submission and withdrawal; broader than fighting alone. | agonistic interaction | The agonistic category included a retreat without physical fighting. |
| 63 | aggression | Behaviour directed towards threatening or harming another individual, as defined in the study. | directed aggression | The aggression classification used actions rather than the adjective “nasty”. |
| 64 | submission | Behaviour associated with yielding or acknowledging a dominance relationship under a species-specific interpretation. | submissive behaviour | The submission interpretation relied on the source’s behavioural evidence. |
| 65 | dominance | An asymmetry in relationships reflected in patterns of interaction outcomes or priority; not simply a permanent personality trait. | dominance relationship | The dominance relationship was described between specified individuals. |
| 66 | hierarchy | An ordered pattern of relationships or ranks under stated criteria; its structure must be demonstrated. | dominance hierarchy | The hierarchy was not inferred from body size alone. |
| 67 | coalition | Two or more individuals acting together in a particular interaction; distinguish it from a lasting alliance. | temporary coalition | The coalition involved coordinated participation in the fictional encounter. |
| 68 | tolerance | Allowing another individual’s presence or activity under specified conditions; it need not imply affection. | feeding tolerance | The tolerance record concerned one feeding context rather than every situation. |
| 69 | competition | Interaction involving limited resources or opportunities used by more than one participant. | resource competition | The competition explanation required evidence about the relevant resource. |
| 70 | reconciliation | Post-conflict affiliative contact interpreted through appropriate comparative criteria; not a human apology by default. | post-conflict reconciliation | The reconciliation hypothesis needed a pattern beyond a single later contact. |
These general concepts help readers understand behavioural research. They do not supply a social ranking for any Bioko group or imply that all primates organise social life in one hierarchy.
Learning terms describe processes, not a ladder from foolish to clever animals. A different response might reflect learning, fatigue, context or something else; choose the explanation the evidence can actually support.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 71 | play | Behaviour with characteristic forms and contexts that is not serving only its immediate apparent practical function; operational criteria matter. | social play | The play classification used the source’s criteria rather than the observer’s amusement. |
| 72 | exploration | Investigation of an environment, object or opportunity through relevant actions. | object exploration | The exploration record described manipulation without claiming a new tool tradition. |
| 73 | habituation | A reduced response to repeated stimulation not explained merely by sensory adaptation or motor fatigue; not permission to approach wildlife. | habituation learning | The habituation concept was studied on paper, not attempted with wild monkeys. |
| 74 | sensitisation | An increased responsiveness following stimulation or experience under appropriate criteria. | behavioural sensitisation | The sensitisation explanation was distinguished from simply encountering a louder sound. |
| 75 | conditioning | Learning involving relationships among stimuli, responses or consequences under a specified paradigm. | associative conditioning | The conditioning term was explained without proposing an experiment on wildlife. |
| 76 | social learning | Learning influenced by observing or interacting with other individuals. | social learning process | The social learning claim needed more than two animals performing similar actions. |
| 77 | imitation | Copying an observed action under a defined learning interpretation; similarity alone is insufficient evidence. | behavioural imitation | The imitation hypothesis was compared with other explanations for the matching action. |
| 78 | innovation | A new or novel behavioural solution relative to the relevant individual or group framework. | behavioural innovation | The innovation label required a clear statement of what counted as new. |
| 79 | flexibility | Capacity to vary behaviour in response to changing conditions; criteria and scope matter. | behavioural flexibility | The flexibility comparison used more than one situation. |
| 80 | weaning | The transition away from dependence on maternal milk; a process rather than necessarily one abrupt event. | gradual weaning | The weaning discussion did not assign one age to every primate species. |
An institutional account can introduce a concept without establishing a mechanism for every action in an example. Do not infer an animal’s full cognitive capacity or emotional experience from an entertaining short clip.
A behavioural category needs boundaries. “Moved” might cover a head turn, a step or a journey across the forest. Define the question before comparing the totals.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 81 | ethogram | A defined catalogue of behaviours used for systematic description and coding. | study ethogram | The ethogram explained what the classroom code meant. |
| 82 | operational definition | A specification of how a concept is recognised or measured in a particular investigation. | behavioural operational definition | The operational definition identified which visible actions counted as an approach. |
| 83 | bout | A continuous episode of a defined activity, bounded by stated criteria. | feeding bout | The bout ended when the fictional record met its specified stopping rule. |
| 84 | state | A relatively lasting behavioural condition that can be measured through duration or sampled over time. | behavioural state | The resting state was distinguished from a brief contact event. |
| 85 | event | A relatively brief, discrete occurrence under a coding system. | behavioural event | The event was recorded as occurring at a particular point in the sequence. |
| 86 | duration | The length of time for which a defined activity or observation lasts. | bout duration | The duration belonged to the recorded episode, not the animal’s whole day. |
| 87 | frequency | The number of occurrences of a defined event, sometimes expressed relative to time; state the denominator. | event frequency | The frequency comparison used the same event definition in both records. |
| 88 | latency | The time between a defined starting event and the beginning of a response. | response latency | The latency had no meaning until its start and response were specified. |
| 89 | inter-observer agreement | The extent to which different observers classify the same material consistently under a stated measure. | assessed inter-observer agreement | The inter-observer agreement improved after the ambiguous category was clarified. |
| 90 | occlusion | The blocking of a subject or feature from view by another object or body part. | visual occlusion | The occlusion was recorded as missing visibility rather than inactivity. |
The definitions here support reading and a fictional classroom coding task. They are not a validated ethogram for a named species. No arbitrary observation thresholds are presented as a research standard.
Behavioural explanations operate at different levels. An immediate trigger and an evolutionary account can both matter, but they are not the same answer to the same question.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 91 | stimulus | A detectable change or event capable of eliciting or influencing a response under the relevant context; plural stimuli. | auditory stimulus | The stimulus was identified without assuming every animal detected it. |
| 92 | response | An action or change following or associated with a stimulus under the study’s criteria. | observed response | The response was recorded before its possible function was proposed. |
| 93 | context | The surrounding conditions needed to interpret an action or interaction. | social context | The context included the preceding interaction rather than one isolated frame. |
| 94 | function | The role or effect of a behaviour under an explanatory framework; not necessarily conscious intention. | proposed behavioural function | The function hypothesis was not treated as a statement of what the animal planned. |
| 95 | proximate explanation | An account of immediate mechanisms or development contributing to a behaviour. | proximate explanation of behaviour | The proximate explanation asked how the response was produced. |
| 96 | ultimate explanation | An evolutionary account of a behaviour’s history or fitness-related consequences; not a conscious goal. | ultimate explanation of behaviour | The ultimate explanation concerned evolution rather than a secret long-term plan. |
| 97 | anthropomorphism | Attributing human characteristics or interpretations to non-human subjects, sometimes without sufficient evidence. | unwarranted anthropomorphism | The anthropomorphism appeared when the caption called a retreat an apology. |
| 98 | inference | A conclusion drawn from evidence rather than a direct description of what was observed. | behavioural inference | The inference was identified separately from the recorded movement. |
| 99 | alternative explanation | Another account compatible with some or all of the evidence that should be considered. | plausible alternative explanation | The alternative explanation involved changing visibility rather than a change in activity. |
| 100 | generalisability | The extent to which a finding applies beyond the studied subjects or conditions. | limited generalisability | The generalisability discussion kept one group from becoming every monkey in Equatorial Guinea. |
A humane account can recognise rich animal lives without inventing motives, and a precise account need not deny that animals have experiences. The task is to match the claim with the kind of evidence available.
Worked example: the friendly branch problem
Here is an invented observation, not a field record from Bioko: “At 0 seconds, A is on a branch. At 4 seconds, B moves closer. At 6 seconds, A moves to a different support. From 7 to 15 seconds, foliage blocks A from view. At 16 seconds, A is visible sitting elsewhere.” No call recording, relationship history or food information is supplied.
A first draft says, “A disliked B and hid because they had quarrelled.” That sentence has sprinted well beyond the record. We know that B approached and A subsequently moved. We do not know the motive, whether the foliage was deliberately used as concealment, or whether an earlier conflict occurred. Sequence can invite a question about cause without answering it.
A more precise version is: “B approached A. A then moved to another support and became obscured by foliage. Its behaviour during the obscured interval was not classified. The record does not establish why A moved.” The revision is not emotionally chilly. It is fair to the animal and useful to the next reader, who can now distinguish the action from the missing information.
For a paper-based coding exercise, supply one deliberately limited definition: approach means movement that reduces the distance between the two drawn figures. Ask two learners to identify that movement in a sequence of sketches. They may disagree because one sketch omits the starting position. That is a problem with the available evidence, not necessarily a careless observer.
The diagnostic breakpoint comes when the learner encounters “not visible”. If it becomes “resting”, explain that missing access is not a behaviour category. If that distinction is secure but the written answer becomes a list of fragments, teach temporal connectors: first, then, during the interval and afterwards. The same record can reveal a scientific misunderstanding or an English organisation need; the correction should match the cause.
What Bioko contributes to the learning question
Drexel’s 2016 account of research on Bioko describes associations between hunting evidence and monkey abundance, and discusses possible behavioural explanations for differences among species. Treat those explanations with the qualification the source uses. A proposed change in vocalising or detectability is not a newly measured universal rule for all monkeys, all forests or the present day.
Its 2019 account identifies a research partnership with the National University of Equatorial Guinea. That matters educationally: the scientific story involves institutions, local expertise and continuing relationships, not merely an overseas visitor discovering an unnamed forest. We do not use that historical article to promise a current study-abroad place, name today’s staff or establish present access to a research site.
An invented mini-dialogue keeps the method in view. Lina: “The animal did not call in this clip, so its species has stopped calling.” Jo: “The clip tells us what was recorded in this interval. A species-wide change would need different evidence.” Lina: “Then the useful question is what the study measured and how it considered detectability.” Jo: “Yes. The question becomes more interesting when it becomes more precise.”
Connect a specialist subject with a learner’s actual task
Equatorial Guinea includes mainland and island settings with different ecological and human histories. Bioko’s monkey research is a particular scientific context, not the whole country. The published Equatorial Guinea learning guide makes those geographical distinctions visible. Use it for broader country enquiry without treating a heritage proposal or an older research story as permission to visit wildlife areas.
A student might need to summarise a behavioural account, distinguish observation from explanation or give an evidence-based presentation. An adult learner may need the same language to read an institutional report. None of these purposes implies one national English syllabus, a particular qualification or a uniform language background. Ask which text and task the learner actually has.
The published English Tuition | Equatorial Guinea guide begins with actual materials and purpose rather than invented curriculum rules. It does not establish a local eduKate centre. For a broader method of organising meanings and applying them in independent sentences, continue to the eduKateSG vocabulary learning hub.
Six behaviour-reading tasks with answers
1. Rewrite “The monkey was rude because it moved away” as an observation and an explicitly unresolved question.
2. An animal is hidden for twelve seconds. Should that interval automatically be coded as resting? Explain.
3. Two observers count different numbers of approaches. Name two things to check before deciding one was careless.
4. Explain the difference between allogrooming and autogrooming, using initiator and recipient where relevant.
5. A brief upright posture is visible. Does that establish habitual bipedal locomotion for the species? Explain the scale change.
6. Give the difference between a proximate and an ultimate explanation without turning either into a claim about an animal’s conscious plan.
Answers and explanations
1. “The individual moved away after the other approached. The record does not establish why it moved.” Rude is a human judgement, not the observable action.
2. No. The action is not visible. Record the occlusion or missing classification under the task’s rules rather than inventing a behavioural state.
3. Check the operational definition and whether both saw the same material under comparable conditions. Ambiguous boundaries or occlusion can produce disagreement.
4. Allogrooming involves grooming another individual; the actor initiates an action directed towards a recipient. Autogrooming concerns one’s own body. A social recipient is not a separate individual in the latter case.
5. No. A brief posture does not establish a habitual locomotor pattern or a species-wide frequency. One event, an individual repertoire and a species-level account are different scopes.
6. A proximate explanation concerns mechanisms or development; an ultimate explanation concerns evolutionary history or fitness-related consequences. Neither necessarily describes a consciously chosen purpose.
Practise a description that survives a changed scene
Begin with behaviour, approach, retreat, posture, allogrooming, signal, context, duration, occlusion and inference. Retrieve each from a new sketch or sentence rather than repeatedly rereading the table. Compare retreat with submission, contact with affiliation, and a visible movement with its proposed function. If the distinction is weak, reduce the number of terms and rebuild that relationship.
For speaking, explain a fictional sequence for one minute using only what the record supplies. Then add a separate, clearly marked possible explanation and say what further evidence it would need. For writing, produce 120 words with three parts: action sequence, missing information and next research question. A concise paragraph can be more scientifically informative than a confident animal biography.
A parent can ask what changed between the first draft and the revision. A teacher can give a second sequence with an obscured interval in a different position and check whether the learner keeps it unclassified. The eduKateSengkang learning guide provides a Singapore-context route for locating a specific weak connection and checking fresh independent use, not a claim of tuition provision in Equatorial Guinea.
Frequently asked questions
Are all examples actual observations from Bioko?
No. All classroom records, example sentences and conversations are invented. The documented country context is separately attributed to institutional research accounts.
Are monkeys and apes interchangeable words?
No. They refer to different primate groups. Size or an appealing facial resemblance does not settle the category.
Does a quiet recording prove an animal made no sound?
Not necessarily. Recording duration, equipment, conditions, visibility and the question being studied all matter. The absence of a recorded call has a limited scope.
Is every retreat submission?
No. Retreat describes movement away under defined criteria. A submission interpretation requires appropriate species-specific evidence and context.
Should learners try to habituate or call to wild primates?
No. This guide uses public resources and invented records. It gives no wildlife-contact, playback, feeding or habituation procedure.
Why include ordinary verbs alongside scientific terms?
Because precise English needs both. Approach and climb carry useful observable meaning; an ethogram or an evolutionary explanation becomes clearer when those actions are described well.
