Psychology Lecture #1
Fundamental Insights of Psych
-psychology research has taught us, and they can deeply change the way you understand
yourself, other people, and the world around you
1) reality is a story, told to us by our brains.
-how do we interact with reality? Truth, the reality that we act in, is one that we
constructed. We hope that LW¶VWKH reality that¶s out there.
-reality: many pieces of information that are coming at you, colours, pressures, smells
-unfortunately, our sensory cannot see all the arrows. Ie, can¶t detect electrical
currents, smells, and some sounds.
-so therefore the many arrows gets narrowed down to a couple arrows. We¶ve cut out
a huge amount of reality. We¶re only dealing with a partial sample of reality.
-We add these arrows up to something we recognize, and that¶s our perception. Our
making sense of all the arrows.
-psychology studies that humans mess up, and we¶re always wrong, but the
perception of our reality is usually right. Its highly functional, most of the time.
-BUT some of our time we¶re wrong, When we can¶t see because it¶s too dark, or
you¶re drunk, and our sensory mechanism is wrong.
-perception is a process of creative story-telling and inference making. We have to fill
in a lot of gaps
-Given this insight, it¶s no surprise that humans ( and animals) generally like the
known, familiar, predictable and fear the unknown, unfamiliar, unpredictable.
But how does the Mind perceive Reality?
-the brain uses it¶s pre-existing patterns (ie, knowledge) to decode incoming sensory
-thus, what the brain has learned to see in the past, is largely what it sees in the
-what it doesn¶t decode, it either guesses (if it has some reasonable info) or ignores
entirely, or just sees what it wants/likes to see
-we are heavily biased to what we already know.
-ie. Perception is a process of PATTERN-MATCHING.
2) We have a limited capacity to process information
-our brains did not evolve to process everything that we experience at once.
-we streamline our brains activating primarily just the µparts¶ that seem reasonable in
-What¶s reasonable? How do our brains decide this?
Æ what has happened recently. Ie, what situation we are in, what information we
have recently accessed in our brains.
-since we are in a situation, our brain has expectations about the class, expectations of
