## 29/7 W1 Lecture 1 ### Cognitive Psychology & Mental Processes - Psychology used to be subjective - "Revolution" came, and now it is only done based off observable behavior. ### Tolman (1948) - Led psychology 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 - Presents the possibility of technological overload - Computers can be used to measure the speed at mental events. - Computer metaphor for the human mind. ### Mental Chronometry: Measuring how long thoughts take - Simple reaction time (SRT) - Choice reaction time (CRT) - (RT-SRT = estimate at stimulus evaluation) - You can actually evaluate mental chronometry by using the additive factors method. ## 30/7 W1 Lecture 2 ### Cognitive Processes - Stimulus | Sensory Detection/Recognition | Response Selection | Response Execution - Early Selection | of meaning | Response Selection | #### Focused vs Diffused Attention - Many inputs are coming in, but you choose 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 Limited? - We only have a certain amount of capacity to process. - We are filtering out things we can't actually act on them. #### Do we have all focus selection early or late? Flexible? - Is the big debate question - Late selection: Processing things you are not paying attention to. (ie. switching cars exercise or hearing your name) #### The Role of Attention: - Parallel pre-attentive process - Serial attention - Treisman (1986): role of attention is to combine things together. #### Control of Attention - Endogenous/voluntary/Controlled: looking for something driven. - Exogenous/Involuntary/Stimulus: grabs your attention, driven. #### Change Blindness - Implies perception of completeness - *fis. int encoded* - Role of attention
