Sensory and Perception Flashcards
simple experiences which arise from the stimulation of sense organs
Sensation
two (2) elements of sensation
- stimulus
- receptors
eight (8) types of sensation
- visual
- auditory
- equilibratory
- olfactory
- gustatory
- tactile
- kinesthetic
- internal senses
visual - location - receptors - stimulus - common defects
visual - retina - rods and cones - lightwaves - monocular defects: myopia, hyperopia, presbyopia, strabismus; visual abnormalities: color blindness, visual paresthesia, hemianopsia, scotoma
auditory - location - receptors - stimulus - common defects
auditory - cochlea - hair cells - soundwaves - nerve deafness, conduction deafness
equilibratory - location - receptors - stimulus - common defects
equilibratory - vestibular canals - cristae - bodily movement - nausea, vertigo, motion sickness
olfactory - location - receptors - stimulus - common defects
olfactory - epithelium - olfactory bulbs - odors / gaseous parts -
process of interpreting stimulus
perception
four (4) characteristics of perception
- Perception is limited to sensory discrimination
- Perception is selective and subjective
- Perception is constant
- Perception has organizing tendencies
5 rules under organizing tendencies
- Figure-ground rule
- Closure rule
- Proximity rule
- Similarity rule
- Continuity rule
three (3) errors of perception
- illusion
- hallucination
- delusion
this error refers to wrong perception
illusion
this error refers to false perception indicative of abnormality
hallucination
this error refers to false belief which can’t be aided with reason
delusion
extra-sensory perception refers to
perception without the mediation of senses, falling under the realm of parapsychology
