Comprehensive Study Guide to Foundations of Psychological Science and Social Psychology
Social Psychology: Attribution, Perception, and Social Cognition
Defining Social Psychology and Person Perception:
Social Psychology: The scientific study of how individual thoughts, feelings, and actions are influenced by the actual, imagined, or implied presence of other people.
Person Perception: The cognitive process through which people form mental impressions, assessments, and categorizations of other individuals.
Impressions are formed automatically in a matter of seconds, prove highly resistant to change, and fill in informational gaps using stereotypes and cultural assumptions.
Attribution Theory (Fritz Heider, 1958):
Posits that individuals make sense of human behavior by attributing causality to one of two distinct sources:
Dispositional (Internal) Attributions: Attributing behavior to enduring internal characteristics, such as personality traits, moral character, intelligence, attitudes, or personal ability.
Situational (External) Attributions: Attributing behavior to environmental variables, situational pressures, systemic context, external constraints, or luck.
Cultural Moderation of Attribution:
Western Individualist Cultures: Prioritize personal autonomy; demonstrate a pronounced default bias toward dispositional explanations.
East Asian Collectivist Cultures: Prioritize relational harmony and group context; demonstrate greater situational awareness.
Attributional Biases and Errors:
Fundamental Attribution Error (FAE):
The tendency for observers, when analyzing an isolated behavior of another person, to significantly overestimate dispositional influences and underestimate situational pressures.
Self-Serving Bias:
The tendency for individuals to attribute their personal successes to internal dispositions (e.g., skill, intelligence, work ethic) while attributing personal failures to external situations (e.g., bad luck, unfair testing conditions), thereby shielding personal self-esteem.
Actor-Observer Bias:
The tendency to explain one's own actions through situational factors ("I was under intense stress") while explaining the identical behaviors of others through dispositional flaws ("They are naturally careless").
Explanatory Style:
An individual's habitual framework for explaining life events across three cognitive dimensions:
Internal vs. External: Is the cause located within me or outside in the environment?
Stable vs. Unstable: Will the cause persist over time or is it a temporary occurrence?
Global vs. Specific: Does the cause apply across all life domains or just this specific event?
Optimistic explanatory styles treat failures as external, unstable, and specific; pessimistic explanatory styles treat failures as internal, stable, and global.
Locus of Control:
An individual's generalized expectancy regarding the forces governing life outcomes:
Internal Locus of Control: The belief that one's personal effort, choices, and actions determine life outcomes; correlated with higher academic achievement, better physiological health, and behavioral persistence.
External Locus of Control: The belief that external forces, luck, chance, or powerful others dictate outcomes; often associated with feelings of helplessness.
The Just-World Phenomenon:
The cognitive bias that leads people to assume that the world is inherently fair and orderly, such that "good things happen to good people and bad things happen to bad people."
Psychological Function: Serves as a defensive coping mechanism, reassuring the individual that unexpected catastrophes will not arbitrarily happen to them.
Harmful Consequences: Directly leads to blaming victims of poverty, physical assault, systemic injustice, or homelessness, while high-status groups use it to rationalize their unearned privilege.
Perception, Interpersonal Expectation, and Comparison:
Mere Exposure Effect:
The psychological phenomenon wherein repeated exposure to a novel stimulus increases an individual's positive evaluation of and liking for it, even in the absence of direct interaction.
Self-Fulfilling Prophecy:
A cyclical process in which an initially false belief or expectation influences behavior in a way that causes the belief to come true.
The Interpersonal Cycle: Our beliefs about ourselves influence our actions toward others; our actions toward others impact their beliefs about us; their beliefs about us cause their actions toward us; and their actions toward us reinforce our beliefs about ourselves.
The Pygmalion Effect (Rosenthal & Jacobson):
An experimental demonstration of self-fulfilling prophecy in academic settings: teachers were told that randomly selected students were on the verge of an intellectual "blooming" growth spurt.
In response, teachers unconsciously provided those designated students with warmer nonverbal cues, more instructional attention, more detailed feedback, and more rigorous academic challenges, causing those students to show higher intellectual growth by the end of the year.
Anecdotal Behavioral Artifacts:
Vocal and behavioral patterns often surface in expressive behaviors under pressure (e.g., an individual loudly proclaiming "CANT DO IT" when attempting to imitate a British accent).
Mirror-Image Perceptions:
Mutual, identical views often held by conflicting parties, where each side sees itself as ethical, rational, and peaceful, while demonizing the opposing side as aggressive, evil, and deceitful.
Social Comparison and Relative Deprivation:
People evaluate their own abilities, status, and happiness by comparing themselves to others.
Social media feeds act as constant comparison engines, broadcasting curated highlight reels that lower personal mood and self-esteem.
Relative Deprivation: The subjective perception that one is worse off or deprived relative to a comparison reference group, even when objective circumstances are stable or improving.
Attitudes, Prejudices, and Cognitive Consistency
The Structure and Measurement of Attitudes:
Attitude: An evaluative feeling, often rooted in beliefs, that predisposes an individual to respond in a characteristic way to people, objects, ideas, or events.
The Tripartite Model of Attitudes:
Cognitive Component: The beliefs, ideas, and factual information held about the target (often taking the form of stereotypes).
Affective Component: The emotional reactions and feelings directed toward the target.
Behavioral Component: The predisposition or readiness to act toward the target in a particular manner (which can manifest as discrimination).
Explicit vs. Implicit Attitudes:
Explicit Attitudes: Conscious, deliberate, and verbally reportable evaluations that individuals recognize.
Implicit Attitudes: Involuntary, automatic, and unconscious evaluations that influence behavior beneath conscious awareness.
Implicit Association Test (IAT):
A computerized measurement paradigm that tracks the reaction time (in milliseconds) required to pair social group images (e.g., race, age, gender) with positive versus negative valence words.
Detects subtle implicit biases that participants may be unaware of or unwilling to disclose.
Stereotypes, Prejudice, and Discrimination:
Stereotype (Cognitive Component):
A generalized cognitive belief about a group of people, applied indiscriminately to all members regardless of individual variation.
Functions as a cognitive heuristic: the human mind naturally categorizes complex stimuli into buckets (analogously to how chemists categorize molecules or coaches organize athletic rosters).
Prejudice (Affective/Evaluative Component):
An unjustified, typically negative attitude toward an entire social group and its individual members.
Shifting Patterns: Explicit, overt prejudices have dropped noticeably in survey data over recent decades, but implicit biases have remained more persistent.
Discrimination (Behavioral Component):
Unjustified, negative, or harmful behavior directed toward members of a group based solely on their group membership.
Generates chronic stress and lowers self-esteem, producing long-term physical and mental health issues for marginalized groups.
Specific Forms of Bias:
Ageism: Pervasive prejudice and discrimination directed against individuals based on chronological age; one of the most socially accepted forms of explicit bias.
Colorism: Systemic prejudice and discrimination that privileges lighter skin tones over darker skin tones within a racial group.
LGBTQ+ Prejudice: Negative attitudes, avoidance, and hostility toward individuals based on non-heterosexual orientations or non-cisgender identities.
Microaggressions: Subtle, daily, often unintentional verbal remarks or environmental slights that communicate hostility, derogatory attitudes, or bias toward marginalized groups. Their psychological harm stems from their cumulative weight over time.
Social and Cognitive Roots of Prejudice:
Social Identity Theory:
People derive self-esteem and belonging from their group memberships, dividing the social landscape into in-groups ("us") and out-groups ("them").
In-Group Bias: The tendency to favor, grant trust to, and positively evaluate members of one's own group.
Scapegoat Theory (Gordon Allport, 1954):
Posits that when individuals experience high frustration, economic hardship, or existential fear, prejudice provides an emotional outlet by directing blame onto a less powerful target group (e.g., historical scapegoating of marginalized groups during economic crises).
Cognitive Load and Heuristic Stereotyping:
Cognitive Load: The total volume of mental processing resources utilized at any given moment.
When an individual is hurried, cognitively overloaded, fatigued, or emotionally stressed, the brain defaults to fast mental shortcuts, leading well-meaning people to rely more heavily on stereotypes.
Out-Group Homogeneity Bias:
The tendency to perceive out-group members as being "all alike" and interchangeable, while viewing members of the in-group as diverse and unique individuals.
Ethnocentrism:
The practice of evaluating and judging other cultures using the standards of one's own cultural group, accompanied by the assumption that one's own culture is inherently superior.
Other-Race Effect (Cross-Race Effect):
The documented tendency to recognize, distinguish, and remember faces of one's own racial group with greater accuracy than faces of other racial groups.
Rooted in social contact and perceptual exposure rather than explicit hostility; contributes to misidentifications in eyewitness testimony.
Mechanisms of Cognitive Consistency and Belief Loops:
Cognitive Dissonance Theory (Leon Festinger, 1957):
The distressing state of psychological tension that arises when an individual's actions directly contradict their internalized beliefs or attitudes.
Modes of Resolution: Because past behavior cannot be undone, individuals most often relieve dissonance by modifying their attitudes to align with their actions, changing future behavior, or constructing rationalizing cognitions.
Belief Perseverance:
The tendency to cling stubbornly to an initial belief even after the empirical evidence that originally established it has been thoroughly disproven.
The Self-Reinforcing Bias Loop:
An interlocking cycle: Cognitive Dissonance induces attitude adjustments to justify behavior, which strengthens Confirmation Bias (seeking only supportive evidence), which solidifies Belief Perseverance, sealing the individual in a self-reinforcing cognitive feedback loop.
Social Influence, Group Dynamics, and Persuasion
Social Norms, Roles, and Conformity:
Social Norms: Explicit or implicit group rules that dictate acceptable attitudes, speech, and conduct for group members.
Social Roles: A set of expectations and behavioral norms linked to a particular social position.
Transformation Mechanism: What an individual enacts, they gradually become; performing a role reshapes the actor's internal attitudes.
The Chameleon Effect and Social Contagion:
Chameleon Effect: The unconscious, automatic mimicry of postures, vocal tones, mannerisms, and facial expressions of interaction partners.
Social Contagion: The spontaneous, rapid spread of emotions, physical behaviors, and ideas throughout a group without conscious intent.
Solomon Asch's Conformity Studies (1951):
Evaluated conformity using an unambiguous visual line-judgment task. Naive participants were surrounded by confederates who unanimously gave clearly incorrect answers.
Approximately one-third of trials resulted in participants conforming to the obviously incorrect group consensus.
Conditions Influencing Conformity Rates:
Conformity increases when a person feels insecure, when the group consists of at least three individuals, when the group possesses high status, and when responses are made publicly.
The Ally Effect: The presence of even a single dissenting confederate who breaks the group's unanimity dramatically reduces conformity.
Dual-Process Social Influence Theory:
Normative Social Influence: Conforming to group behavior to gain social approval, secure acceptance, and avoid rejection or ostracism (conforming to fit in, despite private disagreement).
Informational Social Influence: Conforming because one views the group as a source of accurate information, assuming others understand the situation better than oneself.
Obedience to Authority:
Stanley Milgram's Obedience Experiments (1961):
Tested participants' willingness to obey an authority figure who ordered them to administer increasingly severe electric shocks (ranging from up to a lethal ) to an unseen learner (a confederate).
Over of participants complied fully, administering the maximum shock, despite the learner's recorded screams and protests.
The Banality of Evil (Hannah Arendt):
A concept illustrated by Milgram's findings: great harm rarely originates exclusively from sadists, but rather from ordinary people who uncritically defer to authority and follow orders without questioning their morality.
The Stanford Prison Study (Philip Zimbardo):
Demonstrated how quickly healthy individuals adapt to assigned roles of "guard" and "prisoner" in an authoritarian setting.
The situational pressures and arbitrary power quickly overrode personal moral standards, illustrating that toxic situations can overwhelm individual moral character.
The Psychology of Persuasion and Compliance:
The Elaboration Likelihood Model of Persuasion:
Central Route Persuasion: Focuses on the core substance, logic, and factual strength of the argument.
Requires a motivated, attentive audience; operates slowly, but produces deep, durable attitude change that resists counter-persuasion.
Peripheral Route Persuasion: Relies on superficial cues, emotional appeals, source attractiveness, music, and celebrity endorsements.
Bypasses critical cognitive analysis; triggers rapid acceptance, but yields fragile attitudes that fade quickly.
The Halo Effect:
A cognitive bias wherein an observer's overall positive impression of an individual in one domain (e.g., physical attractiveness) influences their judgments of that individual's unrelated traits (e.g., perceived intelligence, morality, or competence); acts as a potent driver of peripheral route persuasion.
Tactics of Compliance:
Foot-in-the-Door Technique: Securing agreement to a small, trivial request first, which significantly increases the likelihood that the person will later comply with a much larger demand.
Door-in-the-Face Technique: Presenting an initial extreme, unreasonable request that is guaranteed to be refused, immediately followed by a smaller, target request that seems moderate by comparison.
Low-Ball Technique: Getting an individual to commit to an attractive, low-cost offer, after which the costs or terms are revised upward; once committed, people usually fulfill the deal.
The Reciprocity Norm: A universal cultural expectation that we should return favors, concessions, or assistance given to us by others.
Collective Group Behavior, Cultural Norms, and Altruism
Group Influences on Individual Performance:
Social Facilitation vs. Social Inhibition:
Social Facilitation: The tendency for the presence of other people to enhance an individual's performance on simple, familiar, or well-rehearsed tasks.
Social Inhibition: The tendency for the presence of an audience to impair an individual's performance on complex, novel, or unmastered tasks.
The Underlying Mechanism (The Practical Rule): The presence of others triggers physiological arousal, which strengthens the organism's dominant response. For easy tasks, the dominant response is success; for hard tasks, the dominant response is error.
Social Loafing:
The tendency for individuals to exert less physical or mental effort when working collectively in a group than when working alone.
Illustrated by the tug-of-war effect: as more individuals are added to a rope-pulling team, each individual's relative pulling force decreases.
Driven by a reduction in personal accountability and the feeling that individual contributions cannot be isolated or evaluated.
Deindividuation:
A psychological state characterized by the loss of self-awareness and personal restraint that occurs in group settings that combine high physiological arousal with perceived anonymity (e.g., mob violence, riots, online forums).
Group Decision-Making Processes:
Group Polarization:
The tendency for a group's preexisting attitudes to become stronger and more extreme following discussion with like-minded individuals.
Groupthink:
A mode of thinking that occurs when a decision-making group's desire for harmony, conformity, and consensus overrides realistic appraisals of alternative courses of action.
Prevention: Actively designating an individual to serve as a "devil's advocate" to systematically critique plans, encouraging open dissent, and bringing in outside experts.
The False Consensus Effect:
The cognitive tendency to overestimate the degree to which others share our opinions, beliefs, habits, and behaviors; fuels groupthink and polarization.
Conflict, Cooperation, and Macro-Level Social Systems:
Social Traps:
Situations in which conflicting parties, each rationally pursuing their immediate self-interest, become caught in mutually destructive behaviors that produce negative outcomes for everyone involved.
Superordinate Goals:
Shared, overarching objectives that require cooperative effort from conflicting groups to achieve, overriding their hostilities and reducing intergroup conflict.
Industrial-Organizational (I/O) Psychology:
The application of psychological principles, research methods, and theories to workplace environments, focusing on employee selection, training, performance assessment, workplace motivation, organizational dynamics, and leadership styles.
Cultural Dimensions:
Culture: The enduring behaviors, ideas, attitudes, values, traditions, and customs shared by a large group of people and transmitted across generations.
Tight vs. Loose Cultures:
Tight Cultures: Possess clear, rigid social norms and enforce strong behavioral sanctions against any deviations.
Loose Cultures: Maintain more flexible, permissive norms with higher tolerance for unconventional behavior.
Individualism vs. Collectivism:
Individualist Cultures: Prioritize personal independence, individual rights, uniqueness, and self-defined personal goals over collective group needs.
Collectivist Cultures: Prioritize group goals, communal harmony, family duties, and belonging to the collective.
Multiculturalism:
An approach that encourages a society to support diverse cultural groups coexisting while maintaining their unique cultural identities.
Prosocial Behavior, Altruism, and Helping Norms:
Prosocial Behavior: Any voluntary action intended to provide a benefit to another person or group.
Altruism: An unselfish regard for the welfare of others, characterized by helping behaviors that involve no expectation of personal reward or reciprocity.
The Bystander Effect:
A social psychological phenomenon in which an individual is significantly less likely to intervene and offer aid in an emergency when other passive onlookers are present.
Diffusion of Responsibility: The primary psychological mechanism driving the bystander effect: when multiple individuals witness an emergency, each person feels less personally responsible for taking action, assuming someone else will step forward.
Theories Explaining Helping Behavior:
Social Exchange Theory: Suggests that human interactions are transactional; we choose to help when the anticipated benefits (e.g., social praise, relief from internal distress, self-worth) outweigh the expected costs (e.g., danger, lost time, financial expense).
Reciprocity Norm: An internalized social expectation that people will help, and not harm, those who have previously helped them.
Social-Responsibility Norm: An internalized societal expectation that individuals have a moral obligation to help vulnerable people who are dependent on others (e.g., children, the elderly, the injured), even if no personal repayment is possible.
