DO NOW: Figuring Out Who You Are • Take a copy of the article from the stool and read it independently. Decide what you think of it and be prepared to discuss. Keep the following things in mind: • Processing • Perception • Schema • Distortions http://thoughtcatalog.com/2011/the-painful-art-of-figuring-out-who-you-are/
What is Cognition? • Cognitive LoA is new to psychology (40-50 years) • Important way to look at your life – important to be able to think about your thinking (metacognition) • Understanding of perception = awesome. • Do we study this in the lab or in a daily context?
Cognitive LoA • Cognitive psychology: concerns itself with the structure and functions of the mind • Mind: a set of mental processes that are carried out by the brain • Mental processes (cognitions): include perception, thinking, problem solving, memory, language, and attention • Cognitions: based on mental representations of the world such as images, words, and concepts
Principles of the Cognitive Level of Analysis Mental processes guide behavior The mind can be studied scientifically Cognitive processes are influenced by social and cultural factors
What about memory? • Memory = reconstructive nature • Only outlines, not exact copies • false memories • The brain is able to fabricate illusions so realistic we believe they are true
Perception • How do we perceive things? • Perception: the cognitive process that interprets and organizes information from the senses to produce some meaningful experience of the world • Problem: what people think is objective may not be… why? • http://www.youtube.com/watch?v=0jkaSIOqUgY
In groups of 4, consider the questions in the “Be A Thinker” boxon p. 69. Be prepared to discuss. What can a human do that a computer can’t? What can a computer do that a human can’t? Do you think it will ever be possible to construct a robot that can be exactly like a human? http://www.youtube.com/watch?v=FC3IryWr4c8
Donders (1868) • Stroop task
Historical Context: The First Cognitive Psychologists • Donders (1868) • Mental chronometry • Measuring how long a cognitive process takes • Reaction-time (RT) experiment • Measures interval between stimulus presentation and person’s response to stimulus
Historical Context: The First Cognitive Psychologists • Donders (1868) • (a) Simple RT task: participant pushes a button quickly after a light appears • (b) Choice RT task: participant pushes one button if light is on right side, another if light is on left side
Historical Context: The First Cognitive Psychologists • Donders (1868) • Choice RT – Simple RT = Time to make a decision • Choice RT 1/10th sec longer than Simple RT • Mental responses cannot be measured directly but can be inferredfrom behavior
