- Ch 1,2,3,4
Main concepts
1:
Mental responses inferred from behaviour, infer cognitive activity
Donders: reaction time (stimulus vs choice)
Ebbinghaus: memory; the longer the delays to learn a list, the smaller the savings
(savings curve: how much is forgotten after a delay)
wundt: introspection, structuralism (combination of sensation), analytic introspection
Watson: behaviorism (lil albert)
Skinner: operant
Tolman: cognitive maps (trained rats ho have map layout in mind)
Language acquisition: imitation and reward (skinner), unique and nativist (chomsky)
Cognitive revolution: shift from behaviorism to operations of mind
- Info processing approach
- Dichotic listening task: competing info, focus
- Broadbent's flow (input, filter, detector, memory)
- Atkinson (sensory memory, short term/working, long term)
- Tulving's memory types
- Mccarthy AI
Physiology
- EEG, PET, MRI, fMRI
- Knowledge of environment influences cognition (blob test)
Cognitive processes interact with each other and with noncognitive processes
(motivation – learning ; knowledge – perception)
Theory provides: explanation and basis of prediction
Research methods:
- Lab exp (ecological validity), Psychobiological research (cognitive w/
physiological), self-reports, case studies, natural obs, ai

, 2:
Neurons, nerve net, golgi stain (synaptic gap), neurotransmitters, action potential,
electrochemical (adrian)
Anatomy:
- Soma, dendrites, axon, terminal buttons, myelin sheath
Resting potential: -70mV inside
Action potential: nerve impulse from stimulation goes down axon and opens membrane
channels, becomes +40mV
Complex stimulus firing (very specific like geometry and faces)
Feature detectors: neurons for specific stimulus
- Wiesel, break down complex stim to simpler components
Exp dependent plasticity (cooper and vertical stripes and cats)
- Depressed brain activity in deprived env.
- Mothers have more grey matter in maternal motivation and affection (kim)
Hierarchical processing: perception goes from lower to higher areas of the brain in
correspondence to complexity (lines, to shapes to objects to faces)
problem of sensory coding: how info translated into signals our brains can understand
- Specificity coding (1 neuron for 1 stimulus)
- Population coding: pattern represents each specific thing
- Sparse coding: small group of neurons
Localization (broca and wernicke), cortical equipotentiality (opposite)
Fusiform face area (FFA – holistic processing), prosopagnosia (cant recognize faces),
thatcher effect (FFA only for upright faces)
FMRI, voxels, FFA, Parahippocampal place area, Extrastriate body area, lateral
occipital complex (object and shape)
Distributed representation: multidimensional responses (track weighted imaging –
function and structure imaging)
Connectome: a map of connections, functional connectivity (not always direct
pathways
- Resting state fMRI: fMRI resting at 2 spots, calculate correlation
- Default mode network (rest, sleep, creativity, mind wandering, monitoring
emotions)
3:
Perceiving machine
Inverse projection problem (determine 3D object from 2D retina scan)
Blurring difficult
Viewpoint invariance: recognize different perspectives of object
