- cognitive psychology 2
- approaches to studying cognition
- Experimental cognition
- experimenter controls variables to study one particular variable or system
- Structures are deduced indirectly as a result of measurements of accuracy
- Cognitive neuropsychology
- cognitive systems deduced based upon brain injuries or abnormalities
- very small sample. relies heavily on double dissociations
- assumes modularity of mind (Fodor, 1983) - one area damages one particular or a set of functions are affected
- cognitive systems deduced based upon brain injuries or abnormalities
- Cognitive neuroscience
- Brain imaging techniques - Single unit recording, EEG, PET, fMRI, TMS
- Computational cognition
- Artificial intelligence - physical electronics and computer programs
- Connectionism - explaining intellectual abilities using artificial neural networks
- Abstract associative networs
- Experimental cognition
- Applications of cognitive psychology
- product design - artificial intelligence
- Visual behaviour such as driving and road safety
- Object/face recognition i.e. airport security
- Social interaction - social perception, ingroups/outgroups
- Information flow
- Bottom-up
- data driven
- begins with an analysis of sensory input
- perception is built up from low level information
- Top-down
- Concept driven
- high-level cognitive influences
- Knowledge and experience influence our perceptions of the world
- Serial processing
- Piecemeal processing - bottle-neck and sequential
- Parallel processing
- Bulk processing - late/no bottleneck, consecutive
- Bottom-up
- approaches to studying cognition
