Final answer:
Children taking more candy while wearing masks or makeup is an example of deindividuation. This psychological state involves a sense of anonymity and diminished accountability within a group, leading to behaviors not typical if the individual were identifiable.
Step-by-step explanation:
The behavior observed among the children on Halloween night is an example of deindividuation. This psychological state occurs when an individual feels a sense of anonymity and diminished accountability due to being part of a group. In the context of wearing masks or makeup, children are more likely to feel anonymous and, as a result, may feel less responsible for adhering to social norms, such as only taking one candy, leading to taking more than what was permitted.
Deindividuation can lead to actions that an individual ordinarily would not engage in if they were alone or clearly identifiable. This concept is distinct from group facilitation, polarization, or groupthink, as it specifically involves a loss of self-awareness and a decrease in the fear of negative evaluation by others. In contrast, group facilitation involves performance improvement in the presence of others, polarization refers to the tendency for group discussion to intensify group opinion, and groupthink describes poor decision-making within a group due to the desire for harmony and conformity.
