PSYC 1101 Chapter 4: Personality
Document Summary
We have 2 decision making systems: unconscious, emotional, jumps to conclusions, and logical, deliberative, conscious, slow and requires time. We have decision fatigue (get tired after making lots of decisions). We have a limited resource account of decision making, self regulation, and active initiative. Hungry judges make harsher sentences, we get tired car shopping because there are so many cars. We deal w/ uncertainties by applying mental shortcuts: heuristics (representativeness, availability, anchoring) representativeness : perception of randomness if the population is random, the sample should not have structure" anything truly human is inherently variable and inconsistent. One unexpected measurement error is regression to the mean. 1st measurement will tend to get closer to the center on a linear measurement. Phenomenon: basketball players that scored high first ended up scoring lower in later games. Can also explain perverse contingencies" - punishment can lead to improvement, praise to bad performance. Nemeroff & ronzin (1989): you are what you eat.
