Sensation (detection)
|
the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment. |
|
Perception (interpretation)
|
The process by which our brain organizes and interprets sensory information |
|
Transduction
|
changing one form of energy into another |
|
Eye
Iris Pupil Retina Fovea Rods Cones (Color) |
Iris: colored circle around the eye Pupil: black whole that lets light in Retina: the light sensitive inner surface of the eye; contains receptor rods and cons plus layers of neurons that begin the processing of visual Fovea: the central point of the eye Rods: black and white/ night vision Cones: color vision |
|
Young-Helmholtz trichromatic theory
|
the theory that the retina contains three different color receptors- one most sensitive to red, one to green, one to blue, when stimulated in combination these cells can produce the perception of any color. |
|
Opponent-Process theory
|
the theory that opposing retinal processes (red- green, yellow-blue, white-black) enable color vision for example some cells are turned off by green and turned on by red. |
|
Gestalt Laws of Organization
|
Gestalt: Whole is more than the sum of its parts( Gestalt psychologists emphasized our tendency to emphasize our tendency to integrate pieces of information into meaningful wholes)
Figure-Ground Proximity Continuity Closure |
|
Figure-Ground
|
the organizations of the visual field into objects that stand out from their surroundings (the ground). |
|
Proximity
|
we group nearby figures together. |
|
Continuity
|
we perceive smooth, continuous patterns rather than discontinuous ones. |
|
Closure
|
we fill in gaps to create a complete, whole object. |
|
Depth Perception
|
the ability to see objects in three dimensions, although the images that strike the retina are two dimensional; allows us to judge distance. |
|
Binocular Cues |
Binocular cues: a depth cue, such as retinal disparity, that depends on the use of two eyes. Retinal Disparity Convergence (from lecture) |
|
Retinal Disparity |
a binocular cue for perceiving depth. By comparing images from the two eyes, the brain computes distance - the greater the disparity (difference) between the two images the closer the object |
|
Convergence (from lecture) |
the eyes move towards each other to perceive depth. |
|
Monocular Cues |
Monocular Cues: a depth cue, such as interposition or linear perspective available to either eye alone. Linear Perspective Interposition |
|
Linear Perspective |
parallel lines appear to meet in the distance and give the illusion of distance. |
|
Interposition |
when an object is blocked by another object we perceive the object blocking the other object as closer |
|
Learning |
the process of acquiring, through experience, new and relatively enduring information or behaviors. |
|
Associative Learning |
learning that certain events occur together. The events may be two stimuli (as in classical conditioning) or a response and its consequences (as in operant conditioning) |
|
Ivan Pavlov |
Pavlov classically conditioned his dogs to salvate to the sound of a bell |
|
NS, UR, US, CR, CS |
(NS) Neutral stimulus: stimulus that evokes no response before conditioning (UR) unconditioned response: an unlearned naturally occurring response (US) Unconditioned stimulus: a stimulus that unconditionally, naturally and automatically triggers a response (CR) Conditioned response: a learned response to a previously neutral (but now conditioned) stimulus. (CS) Conditioned Stimulus: an originally irrelevant stimulus that after association with an unconditioned stimulus comes to trigger a conditioned response. |
|
John B. Watson (Little Albert)
|
Watson and Rayner learned that fears can be learned by an experiment with "little Albert" who they let hold a little white rat and then caused a large frightening noise to startle him. Then they learned that this fear was generalized to other white fluffy things. |
|
Acquisition |
the initial stage when we link a neutral stimulus and an unconditioned stimulus so that the neutral stimulus begins triggering the conditioned response. |
|
Extinction |
the weakening of a conditioned response when an unconditioned stimulus does not follow a conditioned stimulus |
|
Spontaneous Recovery |
the reappearance, after a pause, of an extinguished conditioned response |
|
Stimulus Generalization |
the tendency, after conditioning, to respond similarly to stimuli that resemble the conditioned stimuli |
|
Stimulus Discrimination |
the learned ability to distinguish between a conditioned stimulus and other irrelevant stimuli |
|
Classical Conditioning Applied (lecture) |
Therapy: Systematic Desensitization Advertising: training people to respond to product as stimuli associated with something naturally appealing |
|
B.F. Skinner |
conducted experiments with animals in boxes |
|
Positive and Negative Reinforcement |
Positive: increases behaviors by presenting positive stimuli, such as food. A positive reinforcer is anything that when presented after a response strengthens the response. Negative: increases behaviors by stopping or reducing negative stimuli such as a shock. A negative reinforcer is anything that when removed after a response, strengthens the response. |
|
Positive and Negative Punishment |
Positive: give something that is undesired Negitive: take something that is desired |
|
Shaping |
an operant conditioning procedure in which reinforcers guide actions closer and closer toward a desired behavior |
|
Primary and Conditioned (secondary) Reinforcers |
Primary: an event that is innately reinforcing. often by satisfying a biological need Conditioned (secondary): an event that gains its reinforcing power through its link with a primary reinforcer |
|
Reinforcement Schedules |
Reinforcement schedules: a pattern that defines how often a desired response will be reinforced Continuous: reinforcing a desired response every time it occurs Partial Schedules: reinforcing a response only part of the time results in slower acquisition but is much more resistant to extinction Variable-Ratio Schedules: a reinforcement schedule that reinforces a response after an unpredictable of responses fixed-interval schedule: a reinforcement schedule that reinforces a response only after a specified time has elapsed variable-interval schedule: a reinforcement schedule that reinforces a response at unpredictable time intervals |
|
Contrasting Classical and Operant Conditioning |
Classical: a type of learning in which we learn to link two or more stimuli and anticipate events Operant: a type of learning in which behavior is strengthened if followed by a reinforcer or diminished if followed by a punisher |
|
Cognitive Learning |
the thoughts and processes that occur in the mind that help the learning process |
