social approach Flashcards
assumptions of the social approach
- behaviour, cognitions and emotions can be influenced by other individuals
- behaviour, cognitions and emotions can be influenced by groups or social contexts
aims of yama
- whether chimpanzees can understand the needs of conspecifics
- whether chimpanzees can respond to those needs with targeted helping.
meaning of altruism
The willingness to do certain things/doing certain things for someone else (1 mark)
even if it disadvantages yourself/gain no benefit (1 mark)
meaning empathy
The ability to understand the emotional state of someone else (1 mark)
by imagining what it would be like to be in that situation (1 mark)
meaning of prosocial behaviour
any action or behaviour that has the intention of helping others
IV of yama
was the ability of the chimpanzee to give targeted helping to another chimpanzee.
two conditions in yama
- In the first, the potential helper chimpanzee was able to see the other’s tool- use situation,
- in the second they could not see.
what was the experimental design of yama
The study used a repeated measures design, which means that all the chimpanzees took part in both conditions of the experiment.
DV of yama
was the targeted helping behaviour.
- This was operationalised as the items offered by the participants to conspecifics (offer, no offer, offer of tool other than stick or straw)
- The item offered was either the correct tool (stick or straw, depending on situation) or an incorrect non-tool item (e.g. a belt).
how was the DV measured in yama
video camera recording
describe sample in yama
5 chimpanzee participants who were socially housed within the Primate Research Institute at Kyoto University took part in this study.
Each had previously been a part of a number of other perceptual and cognitive studies, including some investigating helping behaviour in a similar setting to the present study.
Ai, Cleo, Pal, Ayumu and Pan.
They were paired wit a kin: Ai (mother) and Ayumu (juvenile); Pan and Pal; Chloe (not tested in experimental condition) and Cleo
what were the names of the pps in yama
Ai, Ayumu, Cleo, Pan, Pal
what were the 7 objects in yama
stick, straw, hose, brush, rope, brush, belt
describe the familiarisation phase in yama
8,
5-minute trials
each day
that allowed the chimps to explore the 7 items where they could examine and manipulate all the objects without the need to use them as tools or offer them to others.
how many trials in yama
48 trials
why was can see condition repeated
in order to confirm that any difference in object choice between the first two conditions was due to intentional, targeted helping and not an order effect.
describe the procedure in yama
A chimpanzee had to select a tool that would help the other chimpanzee to solve a problem.
- One task required a stick and the other required a straw. Solving the task allowed the second chimpanzee in the pair to obtain a reward: a juice drink.
Seven objects (straw, stick, hose, chain, rope, brush and belt) were placed in a booth occupied by a potential helper
This could not be reached by the potential recipient but could be requested by the chimpanzee poking his or her arm through a hole to gesture.
This allowed the experimenters to examine whether the potential helper chimpanzee was able to understand what the other needed.
Before any trials started, the chimpanzees went through a familiarisation phase each day (8, 5-minute trials) that allowed the chimps to explore the 7 items where they could examine and manipulate all the objects without the need to use them as tools or offer them to others.
When the experimental trials began, each chimpanzee experienced the conditions in the same order.
Firstly they were placed in the ‘can see’ booth in which the panel between the two chimpanzees was transparent.
Next they completed the task in the ‘cannot see’ booth, in which the panel was opaque.
Finally the ‘can see’ condition was repeated in order to confirm that any difference in object choice between the first two conditions was due to intentional, targeted helping and not an order effect.
Forty-eight trials were carried out in each condition; this consisted of a random order of 24 stick-use and 24 straw- use situations.
Trials began when the tray of objects was presented. The trial ended when the recipient received
the object and succeeded in obtaining the juice reward or after five minutes had elapsed without an object being passed.
‘Offers’ were counted when the chimpanzee held out the object to the recipient, whether the recipient took the object or not.
when was the trial ended in yama
The trial ended when the recipient received the object and succeeded in obtaining the juice reward or
after five minutes had elapsed without an object being passed.
results in first can see condition in yama
- objects were offered 91%
- of these 90% of tools offered were due to the 2nd chimp requesting for helping
- pan was the only chimpanzee who first offered brush as a tool
- This bias suggests that the chimpanzees were able to discriminate between potential tools and non-tools.
results in cannot see condition in yama
- objects were offered 96% of time
- of these 72% of tools offered were due to the 2nd chimp requesting for helping
- pan was the only chimpanzee who first offered brush as a tool
- ayumu was the only chimpanzee who peered thru the hole
what was an important difference was observed between ‘can’ and ‘cannot see’ conditions in yama
can see:
significant difference in which tool was offered first, stick or straw, depending on the task requirement.
cannot see:
no significant difference in which tool was offered first, in all but one of the chimpanzees.
The one chimpanzee named Ayumu who did select the correct tool more often was able to stand and peer through a hole in the wall. He did so in order to view his partner chimpanzee (his mother) and observe the task that she was facing.

results in second can see condition for yama
- objects were offered 98% of the time
- of these 80% were offered upon request for help from 2nd chimp
- only 3 chimps were included - Ai, Pal, Cleo
which 3 chimps were used in the 3rd condition in yama
Cleo , Ai , Pal
why were only 3 chimps were used in the 3rd condition in yama
they had previously shown a significant difference in tool selection in the ‘can see’ condition and a non-significant difference in the ‘cannot see’ condition.
conclusions from yama
- They will offer help to conspecifics who require it in the majority of cases, but usually as a response to a direct request rather than as a spontaneous act.
- Chimpanzees rely on visual confirmation of conspecifics’ needs in order to offer targeted helping
strengths of yama
The method used in this study was a laboratory experiment. There were high levels of control in the
study and a standardised procedure. For example, the presentation of the objects on the tray was the same for each trial, and the chimpanzees sat at the same booths to undergo each trial.
- These measures increased the reliability of the study. Furthermore, the experiment used a repeated measures design. This design meant that the chimpanzees participated in both or all the conditions of the study; reducing any risk of individual differences and increasing validity.
Despite having low ecological validity (lab exp), the chimpanzees had previously taken part in laboratory studies and were therefore familiar with the task and materials used in this research, they probably showed normal behaviour. In this way it could be argued that the study was valid.
Targeted helping was observed using video recording and quantified in a standard way as no offer, offer of tool or offer of other item. Both the way in which the data was recorded and the type of data recorded provide an objective record of helping for each participant.
Other qualitative data was gathered during the experiment such as the behaviour of one chimpanzee who looked over the opaque panel in the ‘cannot see’ condition. This data is important in helping us understand why the chimpanzee then showed an increase in correctly targeted helping
weaknesses of yama
The study had low ecological validity because it was conducted in an artificial environment. The chimpanzees were given tasks and tools that they would not normally use in their natural environment but ^..
The participants in this study were five chimpanzees, and came from the same research institute. This means it was a very small sample that is arguably low in generalisability. It would be difficult to say this sample of captive chimpanzees is representative of wild chimpanzee populations, although there is nothing to suggest that any of the animals was unique or unusual.
why is using repeated measures design a strength in yama
This design meant that the chimpanzees participated in both or all the conditions of the study; reducing any risk of individual differences and increasing validity.
