Psychology midterm
info on basics of psych from bio basis to other gerneral things
| Pyschology Midterm | Answer |
|---|---|
| Cone Cells | handles color vision and responds to light of specific wave length |
| Rod Cells | responds to varrying levels of light. sees dark-light area |
| Adaptation | colors fade/brighten relative to adjacent information |
| opponent process theory | cone cells respond to light of complimenty wave length such as red/gree, blue/yellow. when only shown one side cells will rebound with opponent display of comp. colors |
| color vision | cone cells transfer info to neural impluses, then to other cone cells that determine length of wave |
| motion sickness | vestibular system effects sense of ballances in inner ear. motion sickness occurs from conflicting signals arriving rom teh vestibular system and visual system. |
| Taste | 4 taste buds secetion, Sweet/sour, salt /bitter. sense of smell strong |
| Smell | Olfaction directly connected to limbic system |
| Dorsal Root | information that has travled from skin receptors up spinal cord |
| Afferent Pathway | sensory info that passes through thalamus to cortex |
| Gate theory | multiple sensory inputs compete for dorsal root. minamizing pain in each area. |
| Sleep Stages | 4 stages, trully aslepp in second |
| REM Sleep | brain awake but no muscle tone. happens after 90 minutes reffered to as "paradoxical" sleep |
| Rebound Effect | deprivation of SWS & REM sleep makes people spend more time in deprived stage next night |
| Raphe Nuclei | where slow wave sleep orginates |
| Structuralist | breaks things down to basic elements/ acheived through introspection |
| Fundamentalist | objects baised on function/by driven need |
| Gestalt | interperts environment on basis of organizational rules. no control over information perception |
| Psychoanalytic | influenced by need for pleasure. unconscious controls |
| Behaviorist | no concept of "mind". Behavior is learned through responses to stimuli |
| Humanist | Focus on empathy. everyone can maximize worth. |
| Independent Variable | in an experiment the condition that is manipulated by experimenter t exaine impact on dv |
| Dependent Variable | measure that is affected by manipulation of IV |
| Neuron | recieve info via dendrite and pass info down axon to synapse |
| Action Potential | alters cells internal charge, when reaches a certain level depolarizies and become postive, causing AP |
| Action Potential causes... | rush of sodium and potassion ion into neuron |
| Lock and key | specific neurotransmitter bind with specific receptors allowing passage of chem. into recptor neuron |
| Synapse | action potential causes release of neurotransmitters which trigger post synaptic potential and opens post synaptic membrane |
| Reuptake | taking back unused neurotransmitters in synapse by use of terminal button |
| Autonomic Nervous system | contains Sympathetic and Parasympathetic nervous systems |
| Sympathetic Nervous system | Fight vs. Flight nervous system |
| Parasympathetic system | calms down body after SNS |
| Localization theory | Parts of brain spefic to things like speech - broca's area (expressive) , wernike's area (receptive) |
| Luria's units 1 | regulating and maintaining arousal |
| Luria's unti 2 | receiving, storing, transmitting |
| Luria's unti 3 | excutive functions |
| Split brain research | Corpus collusm seperated. in tests show that right side is not speach doninate like left |
| Left Brain | controls speech |
| Right brain | controls movements, placement, object recognition |
| Frontal Lobe | Planning, coordinating, inhibiting actions, control over cortex, motor relay station |
| Temporal lobe | auditory reception and relay/auditory music memory/ sense of timing |
| Parietal Lobes | Primary somatosensory reception and relay/arithmetic& language organization/ sense of postion&direction |
| Occipital lobes | Primary visual reception & relay/ visual perception |
| sensory& motor areas | Cortical sensory perception/ cortical morot control |
