Connectionist
The process of back propagation is most closely associated with?
Connectionist Networks
The earliest approach to studying categorization was the?
Definitional Approach
The definition of approach to categorization didn't work because?
Definitions often do not include all members of a category
Finke and Pinker's results countered Pylyshyn's argument about tacit-knowledge because it?
Demonstrated that memory couldn't be involved in spatial representations
Definitional approach to categorization
Determine category membership based on whether the object meets the definition of the category -Does not work well -Not all members of every day categories have the same defining features
If someone says "I own a short-hair tabby cat" they would be using the ____ approach to categorization?
Exemplar
If you say that "a Labrador retriever is my idea of a typical dog," you would be using the _____ approach to categorization.
Exemplar
Priming occurs when presentation of one stimulus?
Facilitates the response to another stimulus that usually follows closely in time
The method of understanding categorization used after the definitional approach was the?
Family Resemblance Approach
Paivio (1963) proposed the conceptual peg hypothesis. His work suggests which of the following would be most difficult to remember?
Freedom
Rosch (1975)
Hearing "green" primes a highly prototypical "green"
Why are categories useful?
Help to understand individual cases not previously encountered "Pointers to knowledge" Categories provide a wealth of general information about an item Allow us to identify the special characteristics of a particular item
High overlap vs Low overlap
High family resemblance vs. low family resemblance
The debate between Kosslyn and Pylyshyn is known as the?
Imagery Debate
Shepard and Meltzer's "image rotation" experiment was so influential and important to the study of cognition because it demonstrated?
Imagery and perception may share the same mechanisms.
The "imagery debate" is concerned with whether imagery?
Is based on spatial or language mechanisms
Conceptual knowledge
Knowledge that enables us to recognize objects and events and to make inferences about their properties
One way to help resolve the "imagery debate" is to?
Look at neurological evidence
Kosslyn used ___ to study imagery and perception.
Mental Scanning
Kosslyn's island experiment used the ___ procedure.
Mental Scanning
Pylyshyn argued the opposite of Kosslyn in regards to mental imagery. That is, Pylyshyn suggested that?
Mental imagery is propositional
The "island" experiment results supported Kosslyn's view that?
Mental imagery is spatial
Concept
Mental representation used for a variety of cognitive functions
When Ganis et al. studied brain activation for perception and imagery they found?
Much overlap at the front of the brain but less at the back of the brain
In addition to neuron recordings in brain imaging, we also use ___ to support hypotheses in cognitive psychology?
Neuropsychological evidence
Overall, we can say that ___ "won" the imagery debate
No one because it is still happening today
Low-prototypicality for category "bird"
Penguin
Which of the following is not an affect of prototypicality?
People really high prototypicality items as less "good" examples
Perky's imagery study (1910) had participants describe images of objects that were dimly projected onto a screen. The significance of Perky's results was that?
People were influenced by the projected images when forming their mental images, even when they were unaware that the projected images were present
In attempt to resolve the problems with the different types of evidence, researchers argued that?
Perception uses both high and low areas while imagery uses only high areas
Spreading activation ___?
Primes associated concepts
