The ... condition facilitates chimpanzee's Theory of Mind ability.

The chosen experimental design has positive impact on the validity by ...
reducing participants' variables
reducing order effects
making it replicable
improving ecological validity
Chimpanzees' helping behavior suggest altruism because ...
helpers didn't get the juice
personal relationship between pairs
it was targeted helping
helpers can't see what tool was needed
After doing both conditions, chimpanzees are put to can see condition once more. Why was this necessary?
to reduce fatigue effect
to reduce practice effect
to reduce participants' variables
to improve generalisability
How many trials were conducted in the study?
(a)
What's the percentage of the trials using straw-required task?
25

Give two ways the researchers operationalize an "offer"?
first tool offered
chimpanzee held out an object
tool accepted by another chimpanzee
reward obtained
A trial is ended by one of these two possibilities ...
tool received
five minutes passed
helper chose the right tool
tray of tools were presented
Percentage of objects offer are higher in ...
can see condition
can't see condition
Sticks & straws are popular first offers. This suggests that ...
chimpanzees can identify potential tools
chimpanzees will help without direct benefit
chimpanzees have ToM ability
chimpanzees may have been trained exclusively with both tools
Chimpanzees were able to select the correct tool. This suggests that ...
Helping was targeted, not random
Chimpanzees demonstrates ToM toward conspecifics' need
Bias from former training
Personal relationship between helper & recipient plays role in their helping behavior
Name the chimpanzee who was not able to offer the right tool until an item he kept offering was removed from the tray.
(a)
Name the chimpanzee who outperformed the others in can't see condition because he made extra effort to assess the situation.
(a)
The chosen research method exert high controls in the trials. This improves ...

Procedure was highly standardized, this improves ...
reliability

generalisability
The study's ecological validity is questioned for two reasons:
artificial environment
tasks are not in the nature of the species
too much human intervention
chimpanzees are intelligent
One chimpanzee offered mainly brush first. This suggests ...
bias from former training
personal interest of item
researchers' bias in data
definition of tools are not operationalised
If only they had two observers for every trial, the study will improve in
