Group Influences on Behavior
Ever wonder why you act differently when others are around? Your behavior changes because of social roles and social norms - the unwritten rules we follow in different situations. When people watch you perform tasks you know well, you might do better (social facilitation), but struggle with new tasks (social inhibition).
Group settings create interesting effects. Social loafing happens when people put in less effort in groups (like during group projects when someone doesn't do their share). Groupthink occurs when people change their opinions to maintain group harmony, while group polarization makes opinions more extreme after discussion.
Deindividuation explains why people do things in crowds they'd never do alone - like joining in riots or mob behavior. The famous Kitty Genovese case illustrated the bystander effect, where the more witnesses present, the less likely anyone is to help, due to diffusion of responsibility.
Remember this! When working in groups, be aware of social loafing and groupthink - they can lead to poor decisions and unequal work distribution.
Attitudes form and change through different routes. The central route uses facts and logic, while peripheral routes rely on emotional appeals. We tend to like things simply because we're familiar with them (mere exposure effect). When our actions contradict our beliefs, we experience cognitive dissonance - uncomfortable mental stress we usually resolve by changing our thinking rather than our behavior.

Influence and Self-Perception
Have you ever been told you're good at something and suddenly performed better? That's the self-fulfilling prophecy in action. The Rosenthal-Jacobson study proved this - when teachers believed certain students were "gifted" (though they were actually average), those students performed better because teachers changed their teaching methods and students rose to meet expectations.
Conformity is powerful - we often adopt others' behaviors and beliefs just to fit in. Solomon Asch's famous study showed 75% of participants gave wrong answers to simple questions when others in the room did, proving the Asch Effect - we'll conform even when we know better.
People respond differently to requests versus commands. Compliance happens when we do what's asked of us, while obedience occurs when we follow orders. Marketers and persuaders use specific techniques to increase compliance, like the reciprocity norm (helping those who help us) and clever strategies like foot-in-the-door (starting with small requests before making bigger ones) and door-in-the-face (making a huge request before asking for what you really want).
Think about this: How often do you conform to others' opinions even when you disagree? Recognizing this tendency can help you make more independent decisions.
Stanley Milgram's shocking obedience study revealed that 65% of participants would deliver what they thought were fatal electric shocks when ordered by an authority figure. This explains why people in an agentic state follow harmful orders - they transfer responsibility to the authority.

Social Identity and Bias
We naturally divide our social world into "us" versus "them." Your ingroup includes any social group you identify with, while outgroups are those you don't consider yourself part of. This division creates biases that affect how we treat others.
Ingroup bias causes us to favor people who belong to our groups - like giving the benefit of the doubt to friends but not strangers. Meanwhile, outgroup homogeneity bias makes us see members of other groups as all being alike ("they all think the same way"), while recognizing the diversity within our own groups.
These biases often lead to stereotyping - making overly generalized assumptions about entire groups of people. Stereotypes form through various cognitive shortcuts like diagnostic labeling, confirmation bias, schema formation, and the representative heuristic.
Pro tip: Becoming aware of your own ingroup biases is the first step toward fairer treatment of others. Challenge yourself to recognize when you're making assumptions based on group membership rather than individual qualities.
Understanding these social psychological concepts helps explain why people behave differently in various social contexts - from classroom settings to online interactions to large crowds.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
