Document Summary
Human science - lecture 13 and 14 - week 7. Cognition: any mental process that involves some form of information processing, susceptible to biases and distortions, risk perception, vulnerability estimates, coping strategies, causal attributions. Types of risk: dread, vs non-dread risk, uncontrollable, catastrophic, fatal, not easily reduced, unknown vs unknown risk, unknown to those exposed, delayed e ect, new risk, unknown to science. Implications for perceived threat: more dread and more unknown risks tend to be seen as more threatening, as indicated by the size of the dot, they"re also more over-estimated. Cumulative risk: another bias is under-estimation of aggregate risks from repetition of low risk events, people commonly fail to recognise how rapidly low probability events add up to high cumulative probabilities. Coping strategies: problem focused vs emotion focused, repression and defensive avoidance, monitoring vs bluniting, vary in success, generally active, non avoidant and problem focused strategies work best.
