Lecture 3 F Flashcards
What are the laws of association?
Contiguity
(Closeness of events in space or time)
Frequency
(Greater frequency strengthens association)
Intensity of stimulus - emotional impact
(Greater intensity strengthens association)
Contingency
(When two events are linked - one being dependent on the other)
What is contiguity (law of association)?
Closeness of events in space or time
What is frequency (law of association)?
Greater frequency strengthens association.
What is intensity of stimulus (emotional impact)
Law of association
Greater intensity strengthens association
What is the law of association contingency?
When two events are linked - one being dependent on the other
In order to optimise results what should happen?
Information sent = Message received
What is attention?
The ability to selectively focus on one aspect of the environment
What attracts an animals attention?
Sounds
Scents
Visual stimuli
Tactile stimuli
What is overshadowing?
Overshadowing is when two or more stimuli are present and one stimulus produces a stronger response than the other because is is more relevant or salient (important).
Give an example of overshadowing
Train a dog to preform 2 behaviours
-give each a verbal and a hand signal cue
- test the dog by mixing up the cues
- result? - dog chooses to follow the hand signal
What is sensory pre-conditioning?
A stimulus will become a CS (conditioned stimulus) more rapidly if it has been paired with another stimulus that has since become a CS
What is blocking? Or Kanin blocking?
Kanin blocking refers to failures of learning and/or expressing a CR when a CS is presented to an animal together with a second CS that has already been associated with the unconditioned stimulus
What factors impact upon learning?
Strength of CS Strength of US Attention Salience of stimuli (-overshadowing) Previous associations (-sensory preconditioning and blocking)
