Social Psychology Study Guide

4.1 - Attributions & Perception

Types of Attributions

  • Dispositional (Internal) Attribution – Explaining behavior based on personal traits.

    • Example: "He failed the test because he's lazy."

  • Situational (External) Attribution – Explaining behavior based on external factors.

    • Example: "He failed the test because he was sick."

Attribution Biases

  • Actor-Observer Bias:

    • We blame our actions on the situation (external) but blame others on their personality (internal).

    • Example: If I trip, it's because the floor was slippery; if someone else trips, they're clumsy.

  • Fundamental Attribution Error (FAE):

    • Overestimating personality and underestimating the situation when explaining others’ behavior.

    • Example: Assuming a rude cashier is a bad person rather than considering they had a rough day.

Person Perception

  • Explanatory Style: The way people habitually explain life events (optimistic vs. pessimistic).

  • Locus of Control:

    • Internal Locus – Belief that personal effort controls outcomes.

    • External Locus – Belief that outside forces (luck, fate) control outcomes.


4.2 - Attitudes & Social Thinking

Attitudes & Persuasion

  • Elaboration Likelihood Model:

    • Central Route: Deep thinking, evidence-based. Example: Buying a car based on research.

    • Peripheral Route: Superficial cues (celebrity endorsements, attractiveness).

Cognitive Biases & Persuasion Techniques

  • Halo Effect:

    • The tendency to assume attractive or likable people have other good qualities.

  • Foot-in-the-Door Technique:

    • Getting someone to agree to a small request makes them more likely to agree to a larger request later.

    • Example: Asking for a small donation before asking for a larger one.

  • Door-in-the-Face Technique:

    • Asking for a big favor first, expecting rejection, then requesting something smaller (which seems more reasonable).

    • Example: Asking for $100, getting rejected, then asking for $20 instead.

Cognitive Dissonance Theory (Leon Festinger)

  • We feel discomfort when our attitudes and behaviors conflict, so we adjust one to reduce the discomfort.

    • Example: A smoker knows smoking is harmful → Justifies it by saying "I'm stressed, so it's worth it."

Belief & Biases

  • Belief Perseverance: Holding onto beliefs despite contradictory evidence.

  • Confirmation Bias: Seeking information that supports our beliefs and ignoring opposing evidence.

Prejudice & Discrimination

  • Stereotypes: Generalized beliefs about a group.

  • Prejudice: Unjustified attitude toward a group.

  • Discrimination: Unjustified action based on prejudice.

Biases & Group Dynamics

  • Implicit (Internal) Bias: Unconscious prejudices that affect our behavior.

  • Ingroup Bias: Favoring our own group.

  • Outgroup Homogeneity Bias: Seeing members of another group as "all the same."

  • Ethnocentrism: Viewing one’s culture as superior.

  • Just-World Phenomenon: Believing the world is fair and people get what they deserve (victim-blaming).


4.3 - Social Influence & Group Behavior

Conformity & Obedience

  • Normative vs. Informational Influence:

    • Normative: Conforming to fit in (peer pressure).

    • Informational: Conforming because you believe others are correct.

  • Asch's Conformity Experiment:

    • Line test – People conformed to incorrect group answers.

  • Milgram's Obedience Experiment:

    • Participants followed authority figures and delivered (fake) shocks to a learner.

  • Zimbardo's Stanford Prison Experiment:

    • Demonstrated how roles and situational factors can influence behavior.

Group Behavior & Decision Making

  • Group Polarization:

    • Discussions strengthen preexisting beliefs. Example: Political groups becoming more extreme.

  • Groupthink:

    • Desire for harmony leads to poor decision-making. Example: NASA’s Challenger disaster.

  • Social Loafing:

    • People put in less effort in group tasks. Example: Slacking in a group project.

  • Deindividuation:

    • Loss of self-awareness in group settings (riots, online trolls).

  • Diffusion of Responsibility:

    • Assuming others will take action, leading to inaction.

Helping Behavior & Altruism

  • Social Facilitation:

    • Presence of others improves performance on easy tasks, worsens it on difficult ones.

  • False Consensus Effect:

    • Overestimating how much others agree with us.

  • Superordinate Goals:

    • Shared goals that require cooperation between groups.

  • Altruism:

    • Selfless concern for others.

Bystander Effect & Helping

  • Bystander Effect:

    • People are less likely to help when others are present.

  • Best Odds of Helping Someone Occur When:

    1. We see someone else helping.

    2. The person seems deserving.

    3. We are not in a rush.

    4. We feel guilty.

    5. We are in a good mood.
