Others / Drive
Zajonc et al & and the Cockroaches
This experiment was aimed towards discovering whether cockroaches performed better depending on the complexity of the task.
Cockroaches were put in a maze with a bright light at the start to get them to move away from it
Some mazes were straight, and others were more complex with more turns
Some trials also had cockroaches run alone and in paurs
Some trials had no audience and others had audiences (4 cockroaches)
Cockroaches ran faster on the easy mazes in pairs or with an audience
They were also faster on the compex mazes alone and without an audience
Conclusion: The effect on task performance of coactors or an audience depends on the complexity of the task
Drive Theory does not explain
why a person who is very well practiced
can still not be successful
Drive Theory ignores the role of
cognitive processes (what the person thinks

animal studies that support it
Arousal is low
Complete the table and explain why you would expect different results, according to the two different theories
What happens when you blindfold the audience?
What about animal
Henchy + Glass
same as 3
same as 1 - no social
Social facilitation - improved performance (same as 4)
Social facilitation - improved performance (same as 2)
Same task = distraction
Different task = not distracting
Sanders et al
digit copying task
1. Simple alone
2. Complex alone
3. Simple same (D)
4. Simple different
5. Complex same (D)
6. Complex different
Most mistakes in condition 5!
Most Correct in 3 compared
to 4 +6
A02 - subjective as to
whether same = distraction or not
A02 - Drive Theory
and Eval App Theory
can also explain results
Audience act as a distraction so attention
is split between the distraction and the task.
This conflict of attention is what spikes arousal and drives the dominant response
Here is an example of a
distracting crowd attempting
to put off someone who is
Use the D-C Theory to explain
to explain the influence audience
