Perception opportunity 1 notes

Perception

________ is determined by an interaction between:

Organ of Corti

Ex: When different pitches are played, different receptors along the ________ fire.

Observer

________ is given a standard stimulus and a value for its intensity.

Electrical signals

________ are transformed into conscious experience.

physiology perception

Relationship C: the ________ relationship.

Knowledge

________: any information the perceiver brings to a situation.

Relationship

________ A: the stimulus- perception ________.

Absolute threshold smallest amount of energy

________ needed to detect a stimulus.

Reaction time

________ (RT)- time from presentation of stimulus to observers response is measured.

Environmental stimulus

________ are all objects.

Visual search observers

________ look for one stimulus in a set of many stimuli.

Observer

________ compares the standard stimulus to test stimuli by assigning numbers relative to the standard.

Neural processing

changes

Knowledge

any information the perceiver brings to a situation

Relationship A

the stimulus-perception relationship

ex

A violin and an oboe play the same pitch, 440 hz

Relationship B

the stimulus-physiology relationship

ex

When different pitches are played, different receptors along the Organ of Corti fire

Relationship C

the physiology-perception relationship

ex

When different receptors fire, you report if a note sounds "high" or "low"

Something to Consider

Is There An Absolute Threshold
