Cognitive Psychology, Holt & Goldstein Flashcards
Likelihood Principle
We perceive the object that is most likely to have caused the pattern of stimuli presented to us.
Unconcious inference
Our perceptions are the result of unconcious inferences or assumptions of the environment.
Good continuation
Points that when connected form straight or smoothly curving lines are seen as belonging together.
Pragnanz
“Good figure”. Law of pragnanz/ principle of good figure or principle of simplicity: Perceptual field and objects within it will take the simplest and wholefully encompassing structure within the given conditions.
SIMPLY, we perceive the simplest form structure of stimulus. Think of the olympic rings. We perceive stimulus in the simplest manner possible.
Scene Schema
The knowledge of what an environment or scene typically contains.
Experience-dependent plasticity
The brain is affected by the environment in such way that it changes its structures to perceive the environment more efficiently.
Selective attention
Focusing attention on on stimulus whilst ignoring others
Distraction
Stimulus processing that interferes with processing of other stimulus.
Divided attention
Attention alternating between stimulus.
Attentional capture
Attention captured by the sudden emergence of other more attractive stimulus.
Visual scanning
Movement of eyes between objects, scanning for information
Processing Capacity
How much info can be handled and processed at a given time
Endo/Exogenous attention
Top down/bottom up induced attention.
Treismans Feature Integration theory
At preattentive stage we register features early, automatically and in parallell to each other.
At attentive stage the features are bound and represent separate objects.
Sensory memory
Fraction a second memory of sensoric input that continues in perception after input is gone. This is how we can perceive movies.
Episodic memory
Memory of an experience, i.e picnic in the park with a friend a while back
Procedural memory
Memory used for coordinating muscle movements, riding a bike or climbing.
Semantic memory
Memory of facts and notions of what things are, “that is a bike”
Persistence of Vision
Illusionary visual perception of something that lingers after the eliciting stimulus ends.
Iconic memory
Sensory memory of images.
Proactive interference
Information that was learned/memorized earlier inteferes with the learning of new material.
Retroactive interference
New learning interferes with memory of old learning.
