Social facilitation is the tendency for the presence of others to improve performance on simple or well-practiced tasks but hurt performance on difficult or new tasks, because an audience raises arousal that helps dominant responses and disrupts complex ones.
Social facilitation is what happens to your performance when other people are around. Here's the catch most definitions skip: the effect goes both ways. If the task is easy or well-rehearsed (free throws you've shot ten thousand times, a song you've practiced for months), an audience tends to make you perform better. If the task is hard or unfamiliar (a brand-new skateboard trick, a math problem you just learned), an audience tends to make you perform worse.
The mechanism is arousal. Other people's presence raises your physiological arousal, and arousal strengthens your dominant response, whatever your body and brain do most automatically. For a mastered task, the dominant response is the correct one, so you nail it. For a new task, the dominant response is often a mistake, so you choke. That's the whole model AP Psych wants you to know, and it's covered in Topic 9.4, Group Influences on Behavior and Mental Processes.
Social facilitation lives in Topic 9.4 (Group Influences on Behavior and Mental Processes) in the social psychology unit, where the big question is how the presence and behavior of others changes what individuals do. It sits alongside conformity, groupthink, the bystander effect, and social loafing as one of the core group-influence concepts. It's also one of the most application-heavy terms in the unit. The exam almost never asks you to recite the definition. Instead, it hands you a scenario (an audition, a championship game, a crowd watching skateboard tricks) and asks you to predict or explain performance. If you only remember 'people perform better with others around,' you'll miss every question built on the hard-task half of the concept.

Audience Effect and Co-action Effect (Unit 9)
These are the two flavors of social facilitation. The audience effect is people watching you (a crowd at your audition), while the co-action effect is people doing the same task next to you (cyclists racing each other ride faster than cyclists racing a clock). Both raise arousal the same way.
Evaluation Apprehension Theory (Unit 9)
This theory explains why an audience raises your arousal. It's not mere presence, it's the worry that those people are judging you. That fear of evaluation is the fuel behind the facilitation effect.
Arousal and Performance (Unit 4 / Yerkes-Dodson)
Social facilitation is basically the Yerkes-Dodson law with an audience attached. Moderate arousal helps performance, and the optimal arousal level is higher for easy tasks than hard ones. An audience pushes arousal up, which helps simple tasks and overshoots on complex ones.
Bystander Effect and Diffusion of Responsibility (Unit 9)
A useful contrast within Topic 9.4. Social facilitation is about how others change your task performance; the bystander effect is about how others change your willingness to act. Both show that 'just being around people' is never neutral in social psych.
Social facilitation shows up constantly in scenario-based questions. Multiple-choice stems ask things like how the presence of others affects performance on a well-learned task, or which theory explains poor performance on simple tasks when others are present (that second one is testing whether you know facilitation only helps easy tasks). On free-response questions, it's a regular in applied SAQ scenarios. The 2017 SAQ featured Sachio auditioning for a music scholarship, the 2022 SAQ had Rayce performing skateboard tricks while a crowd gathered, and the 2024 AAQ used Claire's championship basketball game. In every case, the move is the same. Identify whether the task is well-practiced or new, then explain how the audience-driven arousal would help or hurt. Scoring guidelines reward the application, not the definition, so always tie your answer back to the specific person and task in the prompt.
Both involve groups, but they're nearly opposites. Social facilitation happens when you're being watched or evaluated as an individual, so arousal goes up and effort is fully on display. Social loafing happens when your individual effort gets hidden inside a group product (like a tug-of-war or group project), so people coast because no one can tell who's slacking. Quick test: if the person is individually identifiable, think facilitation; if their contribution is pooled and anonymous, think loafing.
Social facilitation means the presence of others improves performance on simple or well-learned tasks but worsens performance on difficult or new tasks.
The mechanism is arousal, since an audience raises arousal and arousal strengthens your dominant (most automatic) response.
On a mastered task the dominant response is correct, so you perform better; on an unfamiliar task the dominant response is often an error, so you choke.
The audience effect (people watching) and co-action effect (people performing alongside you) are the two forms of social facilitation, and evaluation apprehension explains why the audience matters.
Don't confuse it with social loafing, where people exert less effort in a group because individual contributions are hidden.
On FRQs, always state whether the task in the scenario is well-practiced or new before predicting how the crowd affects performance.
It's the tendency for the presence of others to boost performance on simple or well-practiced tasks and hurt performance on difficult or unfamiliar ones. The audience raises arousal, which strengthens whatever response is most dominant. It's tested in Topic 9.4.
No, and this is the most common mistake on the exam. An audience only helps when the task is easy or well-learned. On hard or new tasks, the extra arousal makes performance worse. Multiple-choice questions specifically test whether you know both halves.
Social facilitation is about arousal changing your performance when you're individually visible to others. Social loafing is reduced effort when your work is pooled into a group and no one can identify your contribution. Visible individual performance points to facilitation; anonymous group effort points to loafing.
Both are forms of social facilitation. The audience effect comes from people passively watching you, like a crowd at a recital. The co-action effect comes from others doing the same task alongside you, like runners pacing each other in a race.
Yes, repeatedly. It appeared in the 2017 SAQ about Sachio's music audition, the 2022 SAQ about Rayce performing skateboard tricks for a crowd, and the 2024 AAQ about Claire's championship basketball game. In each, you had to apply the easy-task versus hard-task logic to the scenario.
