Explain social facilitation, social loafing and monitoring

The presence of others can facilitate or impair performance

Social facilitation is a change in individual performance when other people are present. Zajonc’s drive account proposes that social presence raises arousal, making a dominant response more likely. A well-learned or simple task may improve; a new or complex task may become harder if its dominant response is incorrect. This is a prediction to test, not a rule that every audience helps or harms.

Evaluation apprehension gives a different explanation: people may respond because they think others are judging them. Cottrell’s account predicts a stronger effect when the audience can evaluate performance than when others are merely present. Task difficulty, skill, audience and outcome measure matter when comparing explanations.

Social loafing is reduced individual effort in a shared task

Social loafing is a reduction in an individual’s effort when working collectively compared with working alone or coactively, especially when individual contributions are less identifiable. Group performance can also fall because of coordination problems; coordination loss is not the same as reduced motivation.

Latané and colleagues’ social impact theory describes social influence as depending on the source’s strength, immediacy and number. In a group task, adding members can spread responsibility and make each contribution feel less consequential. Identifiable contributions, meaningful goals and clear responsibility can reduce loafing, but no single group size guarantees a particular effort level.

Earley found that group membership interacted with individualism–collectivism

Earley (1993) studied managers and managerial trainees from the United States, Israel and China using a simulated office ‘in-basket’ task and individual, ingroup or outgroup contexts. Individualists performed better alone than when they believed they were working with either an ingroup or outgroup. Collectivists performed better with an ingroup than alone or with an outgroup. A follow-up field survey supported a conceptual replication.

The result suggests that group context and perceived belonging can matter; it does not show that every person in a country shares one value or will perform the same way. Country and measured individualism–collectivism were related in the sample. Cultural labels, managerial samples and a simulated task limit broad claims about all workplaces. Explain the measured pattern rather than stereotyping national groups.

Claypoole and Szalma tested electronic presence in a vigilance task

In Experiment 1, 106 undergraduates were randomly assigned to a control condition (53) or an electronic-presence condition (53). The monitoring condition combined a webcam described as live evaluation with a video recorder described as later evaluation. Participants completed a 24-minute computer vigilance task, detecting two-digit target signals. The equipment did not actually stream or record participants.

Compared with the control group, the electronic-presence group had a higher overall proportion of correct detections, fewer false alarms and faster median responses. Performance still declined over time in both conditions, so monitoring did not remove the vigilance decrement. Because both monitoring devices were used together, Experiment 1 cannot isolate their separate effects; that question belonged to Experiment 2 and is outside the required methodological detail here.

This laboratory study involved undergraduates doing one task, not employees in a real organisation. It offers evidence about concentration in this setup, not a general recommendation for surveillance. Workplace monitoring also raises privacy, trust, consent and fairness questions that the performance comparison alone cannot settle.
