Thinking Geons and "impossible figures": our brain takes shortcuts Necker cube Prototype theory of meaning: we use words closely related to others o Ex: vehicle : car Spreading activation: Thinking about one concept will lead (activate) u to think about concepts related to it. Ex: when u hear the word “flower” u are primed to think “rose”, “violet”, and “carnation”. Stroop effect and automatization: The tendencies to read the word, instead of saying the color of ink its written in. ex: BLUE . When you are speaking, you are primed to say the words you read. When you are pointing, you are primed to point to something nonverbal (such as color). Change blindness: The frequent failure to detect changes in parts of a scene. If you look at a display and a signal calls your attention to one part of the display, you can say what had been there. However, if nothing calls your attention, you notice less and are less able to recall the details of the scene. Ex: shooting a scene on two different days. Viewers will fail to notice the change in clothes, background objects, and change in props. Attentional blink: It takes time to shift attention from one stimulus to the next During a brief time after perceiving one stimulus, it is difficult to attend to something else. (pg. 283) Just as you don’t see something during the brief blink of the eyes, you don’t attend to something after the attentional “blink”. Nature of expertise: Not born an expert; it takes time to become an expert. You must learn every fact about your subject

Hungarian author Laszlo Polgar set out to prove that almost anyone can achieve expertise w/ sufficient effort. His daughter Judit Polgar reached grand master status @ 15 years & 5 months (setting a record). Algorithms and heuristics: Algorithms: a mechanical, repetitive procedure for solving a problem or testing Heuristics: strategies for simplifying a problem or for guiding an investigation. Characteristics of creative people: Non-conformity, risk-taking, willingness to tolerate rejection, openness to new experiences. Unlike expertise, this cannot be taught. People must know a field well before they can make creative contributions to it. However, not so much that they become trapped into traditional habits. They worked in a field of moderate tension where they knew the old ways of doing things weren’t quite right. Didn’t have close relationships, threw themselves into their field. (pg. 292) Representativeness heuristic: The tendency to assume that if something resembles members of a particular category, it probably is a member of that category itself. It usually works but tend to lead us astray when we deal with uncommon events.
