Organizes emotional response patterns, especially aggression and fear. Damage causes people to make stupid risks --> loss aversion
Glial cells
Surround neurons and hold them in place. Outnumber them 10 to 1. May also modulate communication between neurons.
Corpus Callosum
Band of myelinated nerve fibres that connect left and right cerebral hemispheres, allows brain to function as a single unit.
mind-body dualism (or simply dualism)
belief that mind is a spiritual entity not subject to physical laws that govern body (no amount of research into the brain can unravel mysteries of the mind)
Agnosia
Inability to interpret sensory info, damage to visual association area
Basal Ganglia
Critical for voluntary motor control
Axon
Part of a neuron that conducts electrical impulses away from the cell to other neurons, muscles, or glands.
free association
freudian technique, patient expresses any thoughts that come to mind
Wernicke's aphasia (in temporal lobe)
Difficulty in understanding. A receptive disorder. Can string meaningless words together.
developmental psych
human physical, psychological, social development
applied research
uses principles from basic research to solve specific practical problems
basic research
quest for knowledge for its own sake
Alcohol
Bind with receptors for Ach, 5-HT & GABA GABA: prolongs opening of Cl- Channel reducing activity in post synaptic membrane
industrial-organizational psych (I/O)
study of workplace behaviour (employee satisfaction, teamwork, leadership)
Hippocampus
Forming/retrieving memories. Damage leads to short term memory impairment and inability to make short term memory long term.
Cerebral lobes
Frontal, Parietal, Occipital, Temporal
Motor cortex
Controls all muscles involved in voluntary movements. In frontal lobe. More complex/detailed movement takes up more space (Fingers use more than torso)
levels of analysis
biological (brain processes, genetic influences) psychological (thoughts, feelings, motives) environmental (past/present environments one is/has been exposed
Dendrites
Receiving units of neurons, like antennas that collect messages from other neurons and send them to the soma.
clinical psychology
study/treatment of mental disorders (ex. therapists, researchers)
law of effect
behaviours with favourable consequences are likely to recur, unfavourable consequences are unlikely to recur (Thorndike, 1911)
structuralism
analysis of the mind in terms of its basic elements (Titchener and Wundt, 1879)
Hemispatial neglect
Results from damage (stroke) to right hemisphere. You ignore contralateral spatial field (left side does not register). Found in humans because we do not have b
Apraxia
Inability to perform smooth actions due to damage to motor association areas.
repression
primary defence mechanism, keeps unacceptable impulses/feelings in the unconscious
behaviourism
emphasizes the environment controls behaviour via learning, believes that observable behaviour - not the unobservable unconscious - should be the focus (Watson,
Seretonin (5-HT)
Function: Inhibitory and Excitatory Related to: sleep, thermoregulation, implicated in aggression
