Perceptual Process |
is a sequence processes that work together to determine our experience of and reaction to stimuli in the enviornment |
experiencing and reaction |
|
|
4 categories of perceptual process |
Stimulus, electricity, experience and action, and knowledge |
SEEAK |
|
|
STIMULUS |
refers to what is out there in the enviornment when we actually pay attention to, and what stimulates our receptors. |
|
|
|
Electricity |
refers to the electrical signals that are created by the receptors and transmitted to the brain. |
signals to...? |
|
|
Experience and Action |
refers to out goal- percieve, recognize, and react to stimuli |
|
|
|
Knowledge |
refers to knowledge we bring to the perceptual situation. |
|
|
|
Two types of stimuli? |
Enviornmental stimuli and Attended Stimuli |
E & A |
|
|
Environmental Stimuli |
is all of the things in our enviornment that we can potentially percieve |
exp: the potential stimuli presented to ellen, who is taking a walk in the woods. |
|
|
Attended Stimuli |
the stimulus that a person is attending to at a given point. |
paying attention to |
|
|
The Perceptual Process Cycle |
Stimulus: 1. enviornmental stimulus; 2. Attended Stimulus; 3. Stimulus on the receptors ELECTRICITY: 4. Transduction; 5. Transmission; 6. Processing EXPERIENCE & ACTION: 7. Perception; 8. recognition; 9. Action Knowledge... |
how the cycle go thru the process. |
|
|
Transduction |
electrical signals are created in the receptors, which transform energy from the enviornment into electrical signals in the nervous system |
everything we percieve is based on electrical signals in our brain |
|
|
Example of transduction with proper def |
Def: it is the transformations of one form of energy into another form of energy. Exp: withdrawal from ATM; push that button.. pressure exerted by your finger is transduced into electrical energy, which causes the machine to push money out! |
|
|
|
Transmission |
After the moth image has been transformed into electrical signals in Ellen's receptors, these signals activate other neurons, which in turn activate more neurons. it's crucial becasue if signals don't reach the brain,there is no perception. |
one neuron activates another |
|
|
Processing |
As electrical signals are transmitted thru electrical signals in Ellen;s retina and then to the brain, they undergo neural processing, which involves interactions between neurons |
Interaction between neurons; electrical energy is processed thru a network of neurons. |
|
|
Perception |
is conscious sensory experience |
