Comparing the effects of two correction procedures on human acquisition of sequential behavior patterns 下载免费PDF全文
Deitz SM Fredrick LD Quinn PC Brasher LD 《Journal of the experimental analysis of behavior》1986,46(1):1-14
Thirty-one college undergraduates learned to touch abstract stimuli on a computer screen in arbitrarily designated “correct” sequential orders. Four sets of seven stimuli were used; the stimuli were arrayed horizontally on the screen in random sequences. A correct response (i.e., touching first the stimulus designated as first) resulted in that stimulus appearing near the top of the screen in its correct sequential position (left to right), and remaining there until the end of the trial. Incorrect responses (i.e., touching a stimulus out of sequence) terminated the trial. New trials displayed either the same sequence as the one on which an error had occurred (same-order correction procedure), or a new random sequence (new-order correction procedure). Whenever all responses occurred in the correct sequence, the next trial displayed a new random sequence. Each phase ended when five consecutive correct response sequences occurred. Initially, the same-order correction procedure increased control by the position as well as by the shape of the stimuli; also, it produced more errors, more total trials, more trials to mastery, and more individual patterns of reacquisition than were produced by the new-order procedure. 相似文献

Recent work on orientation perception and memory in infants suggest that oblique stimulus orientations are treated as members of a category. The two studies in this report support this hypothesis and extend previous findings by demonstrating that this category includes obliques on either side of vertical even when infants are previously exposed to obliques on only one side. 相似文献

Sensitivity to lexical denotation and connotation in brain-damaged patients: A double dissociation? 总被引:5,自引:2,他引:3
Hiram H. Brownell Heather H. Potter Diane Michelow Howard Gardner 《Brain and language》1984,22(2):253-265
Sets of words can be grouped in terms of their denotation (cold and warm both refer literally to temperature) or in terms of their connotation (cold and warm connote remoteness and intimacy, respectively). To assess whether these two facets of meaning are dissociable, unilaterally left- and right-hemisphere-damaged patients were presented with word triads and asked to group together the two words that were closest in meaning. Right-hemisphere-damaged patients showed a preserved sensitivity to denotation, and a selective insensitivity to connotative facets of meanings. In contrast, left-hemisphere-damaged patients exhibited a preserved sensitivity to connotation as well as a selective insensitivity to denotative aspects of meanings. Inasmuch as normal control subjects displayed a flexible sensitivity to both denotative and connotative aspects of meaning, the results suggest that unilateral brain damage selectively curtails use of one or the other major aspect of word meaning. 相似文献

Children in grades 2–10 (200 of each sex) assigned desirable and undesirable traits to girls or boys. Half the subjects had an additional option of both sexes. Children in all grades assigned more desirable traits to their own sex and more undesirable traits to the opposite sex, in line with Smith (1939). Both sexes became less positive toward their own sex and more positive toward the opposite sex with increasing age. This pattern also had characterized girls in Smith's study, whereas, boys had shown the opposite pattern. Beginning in the sixth grade, girls were more apt than boys to assign desirable traits to their own sex. Availability of the “both sexes” option decreased stereotyping, especially in girls. 相似文献

It is proposed that society should re-examine its assumptions about suicide. Rational suicide is viewed as an extension of the right to die. After a review of the legal liability of the psychotherapist and psychiatric facility for both inpatient and outpatient suicide, the author presents an analysis of philosophical, ethical, and psychoanalytic arguments for allowing rational suicide. It is argued that emotional pain should be given more legitimacy as a reason for suicide. The decision to live or to die is argued to best rest with the individual. 相似文献

Scholars have acknowledged the need to anchor scientific knowledge about social and psychological processes in the norms, values, and experiences of the partticular population under study. This article describes how focus groups can be incorporated into the planning stages of a research pogram to facilitate these goals. After a brief overview of teh central components of focus group research, and example from a program of research involving dual-earner African American families is used to as an illustration. The article describes how (a) the identification of cultural knowledge and (b)access to the language participants use to think and talk about a topic can help researchers formulate a conceptual framework, identify important constructs, and develop appropriate instruments for assessing constructs. Some strengths and limitations of focus group research are discussed. 相似文献
