GROUP MEMORY/ ORG. LEARNING Groups remember more information than individuals Communication of unshared information Groups recognise true information when they hear it o effect is stronger on more simple tasks Transactive memory who remembers what Group mind people adopt a qualitatively different mode of thinking when in a group Group culture Groupthink (Janis) GROUP POLARISATION Tendency for group discussion to produce more extreme decisions than the mean of members’ pre-discussion opinions RISKY SHIFT o tendency for group discussion to produce more risky decisions than the mean of members’ pre-discussion opinions (assuming those opinions already favoured risk) Persuasive arguments theory Social comparison theory SOCIAL IDENTITY THEORY Mental processes involved in evaluating others as “us” (ingroup) or “them” (outgroup) 1.
