## 29 / 7 WL lecture 1 Cognitive Psychology & Mental processes - Psychology used to be subjective A revolution came and now it is only done based off observable behavior. - Tolman (1948) - Led slych studies with rats ... "Stimulus responses!" - Found that rats still learn with no reward or import. - Introduced Skinner (1957) - Wrote works on psychology of language. Chomsky (1967) - Wrote a work that destroyed Skinner's works. The role of technology - Redent's the possibility of technological overload. - Computers can be used to measure the speed of mental events. - Computer metaphor for the human mind. - Amental chronometry: measuring how long thoughts take. - Simple reaction time (SRT) - Choice reaction time (CRT) - (RT - SRT = estimate of stimulus evaluation. - You can actually evaluate mental chronometry by using the additive factors method. ## 30 / 7 WL lecture 2 Cognitive Processes - Stimulus - Sensory detection - Recognition - Response - Action Response - Focused vs diffused attention: Many inputs are coming in, but you are choosing which one to process. It allows for things (often accidents) to go unnoticed. - Inattential blindness: We don't process things we don’t pay attention to. (in our brain) - Why is attention finite? We only have a certain amount of capacity to process Two Theories: - We would have no coordination over anything - We are filtering out things we cannot actually act on them. - Do we have an early selection or a late selection? Is it flexible? - The big debate question - Late selection: processing things you aren't paying attention to - (i.e. Switching cars exercise or hearing your name. - The role of attention: - Parallel preattentive process - Serial attention - Treisman (1986): role of attention is to combine things together. Control of attention - Endogeneous/voluntary/controlled: looking for something. - Exogeneous/involuntary/stimulus: grabs your attention. - Change blindness - Implies percept of completeness - First int encoded - Role of attention.
