Mental set alters visibility of moving targets.
An observer's knowledge of a moving target's direction and velocity enhances detectability. In addition, knowledge of direction and velocity speeds an observer's reaction to the motion of a previously stationary target. Since rival, nonperceptual hypotheses can be ruled out, these effects represent a direct modulation of vision by mental set.
متن کاملCapacity to maintain mental set in dementia.
Two experiments investigating the capacity to sustain mental set in dementia were conducted. Experiment 1 analyzed performance of a non-demented control group (NC), participants with Alzheimer's disease (AD) and participants with ischemic vascular dementia (IVD) on the Boston Revision of the Wechsler Memory Scale Mental Control subtest (MC). On simple tasks there were no between-group differenc...
متن کاملA mental model theory of set membership
Assertions of set membership, such as Amy is an artist, should not be confused with those of set inclusion, such as All artists are bohemians. Membership is not a transitive relation, whereas inclusion is. Cognitive scientists have neglected the topic, and so we developed a theory of inferences yielding conclusions about membership, e.g., Amy is a bohemian, and about non-membership, Abbie is no...
متن کاملA nonclassical symbolic theory of working memory, mental computations, and mental set
The paper tackles four basic questions associated with human brain as a learning system. How can the brain learn to (1) mentally simulate different external memory aids, (2) perform, in principle, any mental computations using imaginary memory aids, (3) recall the real sensory and motor events and synthesize a combinatorial number of imaginary events, (4) dynamically change its mental set to ma...
متن کاملInvestigating the effect of mental set on insight problem solving.
Mental set is the tendency to solve certain problems in a fixed way based on previous solutions to similar problems. The moment of insight occurs when a problem cannot be solved using solution methods suggested by prior experience and the problem solver suddenly realizes that the solution requires different solution methods. Mental set and insight have often been linked together and yet no atte...
