University Study Notes: Interpersonal Processes and Social Psychology Guide

Interpersonal Processes and Relationship Dynamics

• Interpersonal Processes Overview:     * Interpersonal processes encompass how individuals seek out and interact with others, developing relationships, and behaving within social contexts.     * Key areas of study include relationships and attraction, altruism, aggression, and social influence.
• The Need to Belong:     * Social psychologists argue that humans possess a fundamental, possibly innate, need for involvement in relationships (Baumeister & Leary, 1995).     * Individuals act to ensure inclusion by significant others and avoid exclusion or ostracism.
• Interpersonal Attraction Factors:     * Proximity: People often choose friends and lovers from those nearby. There is an estimated $50\,\%-50\,\%$ chance that a romantic partner lives within walking distance.         * Familiarity: Frequent contact breeds affection, possibly an evolutionary mechanism signifying safety.         * Interaction Accessibility: Modern research suggests accessibility (determined by technology/internet) is more critical than literal physical proximity.         * Environmental Spoiling: Close proximity can lead to dislike if bad habits outweigh positive qualities over time.     * Interpersonal Rewards: Based on behaviorist social exchange theories, people maximize the value of their "investments" (personal assets like wit, intelligence, or physical beauty) in the social market.     * Similarity: "Birds of a feather flock together." Similarity in personality traits, attitudes ($r=0.47$), and perceived similarity ($r=0.39$) drive attraction.         * Homophily: The tendency for individuals, particularly adolescents, to affiliate with like-minded friends.         * Complementarity: Occasionally, opposites attract regarding needs or behavioral styles (e.g., dominant and submissive personalities).     * Physical Attractiveness: Attractive individuals receive more cooperation, higher pay, and better treatment by adults and peers.         * Infant Preferences: Infants gaze longer at faces rated attractive by adults, regardless of race or gender.         * Reward Center Activation: Eye contact with an attractive person activates the ventral striatum, a brain region associated with reward.         * Matching Hypothesis: People tend to choose partners perceived as equally attractive to themselves ($r=0.50$ for attractiveness ratings within couples).

Theories and Classifications of Love

• Love as a Story (Sternberg): Love reflects a person's expectations/beliefs. Sternberg identified at least $25$ stories, such as the "traveling story" (a journey), "gardening story" (nuturing), or "horror story" (fear-based).
• Taxonomy of Love (Hatfield):     * Passionate Love: Intense physiological arousal and total absorption in another; usually high at the start of a relationship.     * Companionate Love: Deep affection, friendship, and emotional intimacy that grows over years of shared experience.
• Triangular Theory of Love (Sternberg): Love consists of three components:     1. Intimacy: Feelings of closeness.     2. Passion: Sensual arousal.     3. Commitment: Dedication to the relationship.
• Love as Attachment: Adults pattern relationships on mental models from childhood. Attachment processes (seeking security/proximity) continue into adulthood, even manifesting as depression or anxiety during marital separation.
• Evolutionary Perspective on Love:     * Romantic love is an adaptation fostering reproductive success by bonding parents to care for infants.     * Sexual Strategies: Tactic-based mate selection reflecting different selection pressures.         * Cis Men: Can maximize success by spreading seed widely. Prefer younger (fertile) and attractive partners for long-term bonds to ensure paternity certainty.         * Cis Women: Limited offspring capacity and high investment (9 months of gestation). Usually choosier, preferring partners with resources and commitment.     * Empirical Data: Across $37$ cultures, males valued physical attraction and youth more, while females valued financial prospects and older partners. In Sweden, men preferred partners $5.92$ years younger, while women preferred partners $3.97$ years older.

Relationship Maintenance and the Dark Side

• Maintaining Relationships:     * Australian cohabitation pre-marriage rose from $16\,\%$ in 1975 to approximately $80\,\%$ since 2017.     * Enduring Marriages: Characterized by "coupleness," sharing, liking, and a willingness to adapt.     * Success Factors: Stopping spirals of negative reciprocity, making benign attributions, and having mildly unrealistic positive illusions about a partner.     * Vulnerability: People with low self-esteem struggle with positive illusions, often doubting their partner's regard when threatened.
• The Dark Side:     * Young adults encounter an average of $8.7$ aggravating hassles in relationships per week.     * Ostracism: The "silent treatment" is a powerful tool of hurt within relationships. Experimental participants being ostracized in a simple ball-tossing game experienced significant distress.

Altruism and Bystander Intervention

• Altruism Defined: Behavior helping others with no apparent gain or potential cost to oneself.     * Philanthropy: In 2017-18, $4.43$ million adult Australians donated a total of $\$3.75$ billion.
• Theories of Altruism:     * Ethical Hedonism: All behavior is designed to increase one's own pleasure or reduce own pain. Helping may be motivated by the "aversive-arousal reduction model" (reducing empathic distress).     * Genuine Altruism: Humans may have natural compassion. Helping occurs even when escape from the situation is easy.     * Evolutionary Perspectives:         * Inclusive Fitness: Caring for relatives who share genes.         * Reciprocal Altruism: Helping unrelated others if the long-term benefit outweighs the cost.
• Bystander Intervention:     * Kitty Genovese (1964): Murdered in New York while $38$ witnesses allegedly did nothing. Similar cases occurred in Darwin (1998) and Auckland (2000).     * Darley & Latané Model: Five steps to intervention: (1) Notice event, (2) Interpret as emergency, (3) Assume responsibility, (4) Decide how to help, (5) Act.     * Diffusion of Responsibility: A diminished sense of duty to act because others are present.     * Situational vs. Dispositional: Population density (urban vs. rural) affects rates. High-empathy, high-self-efficacy, and high-emotionality individuals are more likely to help.

Aggression: Theoretical Approaches

• Aggression Types:     * Hostile Aggression: Elicited by anger/perceived injustice.     * Instrumental Aggression: Calm, pragmatic, and goal-oriented (e.g., judicial punishment).
• Societal and Gender Factors:     * Cis men commit over $90\,\%$ of criminal/aggressive acts globally.     * Direct vs. Indirect: Men use physical/verbal aggression; women more frequently use social exclusion or ostracism.
• Roots of Aggression:     * Instinctual (Psychodynamic): Aggression is an inborn potential activated by frustration. Shame is a major trigger for violent individuals.     * Evolutionary: Capacity for aggression evolved for survival, territory, and mate access.         * Life History Theory: A "fast life strategy" (short-term investment, immediate reward) is linked to the "Dark Triad": Narcissism, Psychopathy, and Machiavellianism.     * Biological: Involves the amygdala, hypothalamus, and frontal lobes.         * Testosterone: Linked to social dominance and status-seeking.         * Serotonin: Low levels are linked to impulsivity and unprovoked aggression.     * Cognitive Neoassociation Theory: Aversive stimuli (frustration, heat, odors) trigger negative affect and aggressive thoughts.         * Frustration-Aggression Hypothesis: Blocked goals lead to aggression if they elicit unpleasant emotions.
• The General Aggression Model (GAM): Person variables (traits, attitudes) interact with situational inputs (provocation, aggressive cues) to produce aggressive output.

Social Influence and Obedience

• Deindividuation: Loss of personal identity and accountability in a crowd (e.g., Cronulla riots 2005 or Newcastle Star Hotel riot 1979).
• Obedience (Milgram Experiments):     * Approximately $65\,\%$ of participants administered the maximum $450\text{ volts}$ to a learner because a legitimate authority told them to do so.     * Factors: Proximity to the victim (obedience drops if in the same room) and proximity to the authority figure.
• Conformity (Asch Studies):     * Participants matched line lengths incorrectly $36.8\,\%$ of the time when faced with a unanimous incorrect group opinion.     * Conformity is higher in collectivist cultures and among individuals with low self-esteem.

Group Dynamics and Leadership

• Norms and Roles: Standards for behavior and socially patterned positions (e.g., task leader vs. social-emotional leader).     * Zimbardo's Stanford Prison Experiment (1971): Student volunteers as guards and prisoners became so immersed in roles that the study was aborted after only $6$ days.
• Individual Performance in Groups:     * Social Facilitation: Presence of others helps well-learned "dominant" tasks but hurts complex "non-dominant" tasks.     * Social Loafing: Reduced individual effort in a group setting.
• Group Decision Making:     * Group Polarization: Movement toward extreme positions rather than the middle ground.     * Groupthink: Prioritizing group harmony over critical analysis (Janis, 1972).
• Leadership Styles:     * Autocratic: Efficient but breeds discontent.     * Democratic: Efficient and motivating.     * Laissez-faire: Often results in low satisfaction and inefficiency.     * Fiedler's Contingency Theory: Leadership effectiveness depends on task structure, leader-member relationships, and position power.

Questions & Discussion

• Opening Case: Jack Monaghan:     * Q: What drove 16-year-old Jack to rescue 12-year-old Dakota Drew from a house fire in Brabham (2021)?     * A: A combination of situational variables (proximity, being the only one there) and dispositional variables (fit, interest in firefighting, sense of obligation).
• Dialogue on Identity:     * Coping Strategy: Synthesis of the old and the new—preserving continuity with the past while mooring identity in the future (e.g., Gandhi).
• Relationship Education:     * Q: Are online social networks changing the nature of relationships?     * A: Research is mixed; some see it as social connectedness (satisfying the need to belong), while others find it associated with "Facebook intrusion" and relationship dissatisfaction.
• Dialogue on Ethics:     * Q: Was Milgram's study ethical?     * A: It caused visible distress, leading to the development of institutional review boards, though participants subsequently did not report regretting their participation ("The experiment requires that you continue").
• Application Scenario - Social Influence Tactics:     * Scenario A: Buying a car and being told floor mats cost extra at the last second: Low-balling.     * Scenario B: Asking for a 2-year commitment, then a small day trip when refused: Door-in-the-face.     * Scenario C: Agreeing to interview 10 students, then later agreeing to analyze data: Foot-in-the-door.
