Question 128

A set of three looped tubular channels in the inner ear that detect movements of the head and provide the sense of dynamic equilibrium that is essential for maintaining balance - They form part of the vestibular apparatus - The channels are filled with fluid (endolymph) and are oriented roughly at right angles to each other - Hence they can monitor movements in each of three different planes - Each canal has an enlarged portion, the ampulla, inside which is a sensory structure called a crista - This consists of hair cells whose processes are embedded in a gelatinous cap (the cupula) - When the head moves in a certain plane, endolymph flows through the corresponding canal, displacing the cupola and causing the hairs to bend - This triggers the hair cells to fire nerve impulses, thus sending messages to the brain about the direction and rate of movement

Answer 206

Sign

Question 207

A body of concepts and techniques from communication theory, electrical engineering, and decision theory that were applied to auditory and visual psychophysics in the late 1950s and are now widely used in many areas of psychology - This has provided a valuable theoretical framework for describing perceptual and other aspects of cognition and for quantitatively relating psychophysical phenomena to findings from sensory physiology - A key notion of this is that human performance in many tasks is limited by variability in the internal representation of stimuli due to internal or external noise

Zimbardo (1933 - ) - The paid volunteer participants - both "prisoners" and "guards" - were 24 mostly while male and middle class undergraduate students - Prisoners were "arrested" and "incarcerated" in a simulated jail in the basement of the building housing the psychology department at Stanford University - A variety of methods and situations were used to depersonalize participants, diminish their sense of identity, and increase a sense of power on the one hand (guards) and powerlessness on the other (prisoners) - The experiment was terminated after only 6 days of the originally scheduled 14, because of Zimbardo's realization that it had far exceeded the extent of behavior that was predicted and had led to emotionally and psychologically damaging outcomes; several of the guards were seen to exhibit sadistic tendencies in their treatment of prisoners, and several of the prisoners showed physical manifestations of stress and psychological trauma - Apart from ethical considerations, the study was criticized as methodologically flawed and invalid from multiple perspectives, including the small size of the sample, lack of ecological validity, and lack of sufficient controls - Nonetheless, this is often cited as a demonstration of the way in which social contexts can influence, alter, shape, and transform human behavior

Question 457

A three part test in which (a) color names are read as fast as possible; (b) the colors of bars or other shapes are rapidly named; and, most importantly, (c) color hues are named quickly when used to print the names of other colors (such as the word green printed in the color red) - The degree to which the participants are subject to interference by the printed words is a measure of their cognitive flexibility and selective attention [John Ridley Stroop (1897 - 1973), U.S. psychologist]

Answer 457

Stroop Color Word Interference Test

Question 458

The finding that the time it takes a participant to name the color of ink in which a word is printed is longer for words that denote incongruent color names than for neutral words or for words that denote a congruent color - For example, if the word blue is written in red ink (incongruent), participants take longer to say "red" than if the word glue is written in red ink (neutral) or if the word red is written in red ink (congruent)

Question 460

A type of family therapy that assesses the subsystems, boundaries, hierarchies, and coalitions within a family (its structure) and focuses upon direct interactions between the family members (enactment) as the primary method of inducing positive change - This assumes the competence and uniqueness of families with problems, stressing that when appropriately induced to do so families will discover their own alternatives to their ineffective patterns of relating to one another and that this process of discovery cannot proceed in a specific predetermined form but instead can only be directed toward a fairly well defined area of functioning - For example, this type of therapist working with a family whose daughter is anorexic would examine such family issues as the framework of authority, the rules that govern the assumption of roles, the various functions members perform, and the coalitions created by the bonding of certain family members, and then encourage the mother, daughter, and father to use this information to develop more productive patterns of functioning

Answer 460

Structural Family Therapy

Question 461

1. A movement considered to be the first school of psychology as a science, independent of philosophy - Usually attributed to German psychologist and physiologist Willhelm Wundt (1832 - 1920), but probably more directly influenced by British born U.S. psychologist Edward Bradford Titchener (1867 - 1927), this defined psychology as the study of mental experience and sought to investigate the structure of such experience through a systematic program of experiments based on trained introspection 2. A movement in various disciplines that study human behavior and culture that took its impetus from the radically new approach to linguistic analysis pioneered by Swiss linguist Ferdinand de Saussure (1857 - 1913) - He maintained that linguistic signs acquire meaning not through their relationships to external referents but through their structural relationships to other signs in the same system - This model of language was extended to cover essentially all social and cultural phenomena, including human thought and action, in the work of French anthropologist Claude Lévi-Strauss (1908 - ) - These explanations play down individual autonomy and agency, positivistic science, and linear time causation in favor of explanations in terms of structural and systemic influences operating in the present to produce rule governed behavior, the true nature of which can be revealed as the underlying structures are revealed

Question 520

In the transformational generative grammar of U.S. linguist Noam Chomsky (1928 - ), the structure of a grammatical sentence as it actually occurs in speech or writing, as opposed to its underlying deep structure or abstract logical form - In Chomsky's theory, this of a sentence is generated from the deep structure by a series of transformational rules involving the addition, deletion, or reordering of sentence elements - Psycholinguists have investigated whether and to what extent this may serve as a model for the cognitive processes involved in forming and interpreting sentences

Answer 520

Surface Structure

Question 521

Answer 556

Systematic Desensitization
