Perception |
Unconscious, automatic process based on Unavailable neural events, together with unconscious inference from specific cues |
|
|
Steps in the perceptual process |
Stimulus Electricity or physiology Experience and action |
|
|
The perceptual process: stimulus |
Stimulus in the environment Attend to the stimulus Stimulus on receptors |
|
|
The perceptual process: Electricity or physiology |
Transduction Transmission -> AP Processing |
|
|
Transduction; what is it |
The change of mergers from one state to another |
|
|
The perceptual process: Experience and action |
Perception Recognition Action |
|
|
Bottom up processing |
Information based on the incoming stimulus from the environment |
|
|
Top down processing |
Information based on prior knowledge |
|
|
An experiment that studies the experience/action of participants by change the stimulus practices what type of approach? |
Psychophysical approach (pp) |
|
|
An experiment that studies the physical/chemical response of participants by changing the stimulus practices what type of approach? |
Physiological approach (PH1) |
|
|
An experiment that studies the physical/chemical response of participants by changing the experience/action of the participants, practices what type of approach? |
Physiological approach (PH2) |
|
|
Qualitative methods of psychophysical measurement |
Description Recognition |
|
|
Phenomenological method |
Describing what you see/hear/feel ect. |
|
|
Quantitative methods of psychophysical measurement |
Absolute threshold Difference threshold/ limen Magnitude estimation |
|
|
Absolute threshold |
The smallest amount of energy needed to detect a stimulus |
|
|
Absolute threshold (quantitive) methods |
Method of limits Method of adjustment Method of constant stimuli |
|
|
Methods of limit |
Stimulus of different intensities presented in ascending and descending order Eg. Hearing test |
|
|
Method of adjustment |
Stimulus is adjusted CONTINUOUSLY until the observer detects |
|
|
Method of constant stimuli |
5-9 stimuli of different intensities presented in a random order |
|
|
Limen/ different threshold |
The smallest different between two stimuli a person can detect |
|
|
Weber’s law |
K= deltaL / S Delta L = Limen/ difference in threshold S = initial stimulus |
|
|
Magnitude estimation (scaling) |
Observer estimate the change of intensity via scaling |
|
|
Magnitude estimation; response compression |
As intensity increases, the perceived magnitude increase more slowly than the intensity |
|
|
Magnitude estimation; response expansion |
As the intensity increases the perceived magnitude increases more quickly than the intensity |
|
|
In Stevens power law P = kS^n When will n be small |
N is small for response compression; As intensity increases, the perceived magnitude increase more slowly than the intensity |
|
|
In Stevens power law P = kS^n When will n be large |
Response expansion; As the intensity increases the perceived magnitude increases more quickly than the intensity |
