Q

What is Social Facilitation?

A

When the presence of others enhances performance on easy tasks but impairs performance on difficult tasks (Kassin et al., 2021)

Q

What was Triplett’s cyclist research?

A

Triplett noticed that cyclists who competed against others performed better than those who cycled alone against the clock.

After dismissing various theories of the day (our favorite is “brain worry”), he proposed his own hypothesis: The presence of another rider releases the competitive instinct, which increases nervous energy and enhances performance.

Q

How did Triplett test his hypothesis?

A

To test this proposition, Triplett got 40 children to wind up fishing reels, alter- nating between performing alone and working in parallel. Triplett reported that children were more likely to perform better when they worked side by side than when they worked alone.

Q

What is the Zajonc 3-Step Solution?

A
  1. Presence of others = physical arousal, energizes behaviour
  2. Arousal enhances tendency to perform dominant response
  3. Quality of performance varies
    based on type of task

Q

What was the Zajonc Cockroach Studies?

A

Zajonc and his colleagues (1969) had cock- roaches placed in a brightly lit start box connected to a darkened goal box. When the track was a simple one, with a straight runway between the start box and the goal box, cockroaches running in pairs ran more quickly toward the goal box than did those running alone.

But in a more complex maze that required a right turn to reach the goal box, solitary cockroaches outraced pairs.

In a particularly creative follow-up experiment, Zajonc and his colleagues found that cockroaches completed the easy maze faster, and the difficult maze slower, if they raced in front of a crowd of spectator cockroaches than if they raced with no audience.

How did the researchers get cockroaches to participate as spectators? The researchers placed cockroaches in plexiglass “audience boxes” along either side of the maze, and this “audience” produced social facilitation.

A

Cockroaches were
faster with audience

Q

What is Social Facilitation Research Today?

A
  • Meta-analysis of 241 studies supported social facilitation
  • Many modern examples: driving
    tests, e-gambling
  • Part of why firefighters, police officers, military personnel, and
    others practice scenarios ad nauseum
19
Q

What is Mere presence?

A

The mere presence of others is sufficient to produce social facilitation effects

20
Q

What is Evaluation apprehension theory?

A

The presence of
others will produce social facilitation effects only when those others are seen as potential evaluators

21
Q

What is Distraction-conflict theory?

A

The presence of others
will produce social facilitation effects only when those others distract from the task and create attentional
conflict
