RIGHT!!
Perception - (ANSWER)the process of organizing and interpreting sensory
information, enabling us to recognize meaningful objects and events
Are there really 5 senses? - (ANSWER)No, there are from 7-12 different senses
neural transduction - (ANSWER)receptors, transduction and neural response
Sensation - (ANSWER)activation of sensory receptors due to a stimulus in the
environment (physical stimulus---->neural signal)
Phenomenology - (ANSWER)internal experience that everyone has of the
external world around them
Aristotle and the Five senses - (ANSWER)Aristotle said there were five senses -
smell, sight, touch, taste, and hearing - but science suggests there are many more
than that
Thomas Young - (ANSWER)showed that light, like waves, could be diffracted,
color recptors
,Johannes Mueller - (ANSWER)doctrine of specific nerve energies (distinct senses)
Von Helmholtz - (ANSWER)perception is constructed from both senses and
cognitive processes, unconscious inference, three basic color receptors
Hering - (ANSWER)colors are perceived through 2 pairs of opposing colors (four
primary colors, not three)
Weber's Law - (ANSWER)the just noticeable difference between two stimuli is
based on a proportion of the original stimulus rather than on a fixed amount of
difference
Fechner - (ANSWER)father of psychophysics, the study of the relation between
physical stimuli and the perception they elicit
Fechner's Law - (ANSWER)sensation is a logarithmic function of physical intensity
Gestalt Psychology - (ANSWER)the whole is greater than the sum of its parts
Law of Proximity (Gestalt) - (ANSWER)elements close to one another tend to be
perceived as a unit
Law of Common Fate (Gestalt) - (ANSWER)visual elements that move in the same
speed and/or direction are parts of a single stimulus
, law of closure (gestalt) - (ANSWER)we tend to see complete figures even when
part of the information is missing
Law of Similarity (Gestalt) - (ANSWER)objects that are similar tend to be grouped
together
Law of Good Continuation (Gestalt) - (ANSWER)elements that appear to follow
the same pathway tend to be grouped together
Gibson and Direct Perception - (ANSWER)sensation is perception, what you see is
what you get
Information Processing Approach - (ANSWER)a perspective on understanding
cognition that divides thinking into specific steps and component processes (LIKE
A COMPUTER)
computational approach - (ANSWER)Describes the problem the system is trying
to solve and the constraints it uses in order to solve it, most abstract
microelectrode - (ANSWER)a very fine electrode, generally used to record activity
of individual neurons
Neurophysiology - (ANSWER)explains the workings of the nervous system
