Recall key psychological effects related to behavior changes in social or experimental settings, such as the Hawthorne effect, social loafing, placebo effect, and bystander effect.
Define each option briefly: the Hawthorne effect refers to changes in behavior due to awareness of being studied; social loafing is the tendency to exert less effort in a group; placebo effect involves changes due to expectations of treatment; bystander effect is the reduced likelihood of helping when others are present.
