Group dynamics Study Guide

📖 Core Concepts Group Dynamics – The patterns of behavior and psychological processes that occur within a single group (intragroup) or between multiple groups (intergroup). Intragroup vs. Intergroup – Intragroup = inside one group; Intergroup = relations among distinct groups. Social Identity – Individuals derive part of their self‑esteem from membership in groups; they compare their own group (ingroup) to others (outgroup). Group Development – Typical stages a group moves through as it matures (Forming → Storming → Norming → Performing → Adjourning). Social Facilitation – Presence of others raises arousal/drive, improving performance on simple tasks but impairing it on complex tasks. Group Cohesion – The forces (attraction, solidarity, morale) that keep members connected and willing to work together. Groupthink – A cohesive group’s drive for unanimity that leads to poor decision quality and suppression of dissent. --- 📌 Must Remember Hackman’s 5 Conditions for Successful Teams Real team (clear boundaries, shared task) Compelling direction (challenging, clear goal) Enabling structure (optimal size, skill mix, strong norms) Supportive context (resources, rewards, info) Expert coaching (task & interpersonal guidance) Tuckman’s Stages – Forming, Storming, Norming, Performing, Adjourning (dissolution). Social Facilitation Rule (Zajonc) – Presence of others → Better on dominant/simple tasks, Worse on nondominant/complex tasks. Evaluation Apprehension (Cottrell) – Fear of being judged, not just drive, explains the same performance pattern. Contact Hypothesis (Allport, 1954) – Reduces prejudice if: equal status, common goals, intergroup cooperation, institutional support. Black Sheep Effect – In‑group members who deviate are judged more harshly than similar out‑group members. Minimal Group Paradigm – Even trivial group assignments produce ingroup favoritism. Robbers Cave Findings – Intergroup conflict arises from competition for resources; superordinate goals can reduce it. --- 🔄 Key Processes Group Formation (Social Identity Approach) Identify shared category → perceive “us” vs. “them” → interpersonal attraction solidifies bonds. Decision‑Making under Social Facilitation Presence of others → ↑ arousal → if task → dominant response → performance ↑; else → nondominant response → performance ↓. Reducing Intergroup Conflict (Contact Model) Ensure (a) equal status, (b) common goals, (c) cooperation, (d) authority support → increased intergroup contact → reduced prejudice. Groupthink Avoidance Assign a “devil’s advocate,” break the group into sub‑teams, seek external opinions, and encourage open criticism. Jigsaw Classroom (Aronson) Split content → each student becomes “expert” on one piece → must teach peers → interdependence → higher learning & reduced bias. --- 🔍 Key Comparisons Intragroup vs. Intergroup – Intra: processes inside one group; Inter: attitudes/behaviors between groups. Dominant vs. Nondominant Responses (Zajonc) – Dominant: easy, well‑learned → performance ↑ with others; Nondominant: complex → performance ↓ with others. Evaluation Apprehension vs. Drive Theory – Apprehension: fear of judgment drives the effect; Drive: arousal alone drives it. Primary vs. Social Groups – Primary: small, face‑to‑face, strong emotional ties; Social: larger, formal, weaker ties, task‑oriented. Prescriptive vs. Proscriptive Norms – Prescriptive: what you should do; Proscriptive: what you should not do. --- ⚠️ Common Misunderstandings “Groupthink = no conflict” – Conflict can still exist; it’s the suppression of dissent that defines groupthink. “Social facilitation always improves performance” – Only true for simple/dominant tasks; complex tasks suffer. “All intergroup contact reduces prejudice” – Effectiveness drops if optimal conditions (equality, cooperation, support) are missing. “More cohesion = better outcomes” – Excessive cohesion can increase groupthink and reduce critical evaluation. “Roles are fixed” – Role differentiation can shift as tasks and group composition change. --- 🧠 Mental Models / Intuition “Arousal‑Task Match” – Think of a volume knob: turning it up (arousal) helps a simple song (dominant response) but distorts a complex symphony (nondominant response). “Two‑Level Identity” – Imagine wearing two shirts: one identifies you with a small team (primary), the other with a larger organization (superordinate). Switching shirts changes bias. “Structural Support Ladder” – Hackman’s five conditions stack like a ladder; missing any rung destabilizes the whole team. --- 🚩 Exceptions & Edge Cases Evaluation Apprehension without Audience – Even imagined evaluation can trigger the effect (e.g., video recordings). Contact Hypothesis without Equal Status – Still can reduce prejudice if common goals and institutional support are strong. High‑Skill Individuals – May experience facilitation even on complex tasks because the task is no longer nondominant for them. Cultural Variations – Collectivist cultures may show stronger cohesion and thus higher susceptibility to groupthink. --- 📍 When to Use Which Choose Hackman’s Model when designing or diagnosing a work team’s performance issues. Apply Zajonc’s Theory when predicting how audience presence will affect task execution (simple vs. complex). Use Contact Hypothesis when planning interventions to reduce intergroup bias; first check for the four optimal conditions. Select Jigsaw or Interdependence Techniques for classroom or training settings to boost learning and reduce prejudice. Deploy Devil’s Advocate when you suspect groupthink in decision‑making meetings. --- 👀 Patterns to Recognize “Simple task + audience = faster, more accurate” → social facilitation pattern. “High cohesion + unanimity pressure = risk of groupthink.” “Ingroup favoritism + outgroup derogation = minimal group paradigm outcome.” “Emergent groups → high interdependence, low formal structure (e.g., disaster response). “Black sheep statements → harsher judgment than comparable outgroup behavior.” --- 🗂️ Exam Traps Distractor: “Social facilitation always improves performance.” – Wrong; ignores task difficulty. Distractor: “Groupthink occurs only in large organizations.” – Wrong; can happen in any cohesive group. Distractor: “Primary groups are defined by formal membership.” – Wrong; they are defined by strong, personal, face‑to‑face ties. Distractor: “Contact hypothesis works only if all four Allport conditions are met.” – Over‑strict; partial conditions can still yield benefits. Distractor: “Hackman’s five conditions are optional guidelines.” – Wrong; they are empirically linked to successful team outcomes. ---
