The present research investigated the effects of multiple images on associative learning. In Experiment 1, subjects formed either a noninteractive image of two words, a single interactive image, a multiple interactive image consisting of multiple copies of the same image, or a multiple interactive image consisting of different images. In Experiment 2, the different multiple images were formed across trials instead of simultaneously during the same trial. Both experiments showed that, although interactive images are superior to noninteractive images, there is no reliable facilitation from multiple images as compared with single images. The results were discussed in terms of the variable-encoding hypothesis and previous findings that multiple retrieval paths facilitate verbal learning. 相似文献

Relatively few procedures exist for developing heterosexual arousal in the treatment of sexual deviation (Barlow, 1973) although several recent studies suggest this is a necessary component of treatment (Feldman and MacCulloch, 1971; Bancroft, 1970; Barlow, 1974).In recent years, biofeedback techniques have been applied to many types of disorders (Blanchard and Young, 1974). Basic to biofeedback technology is the notion that providing a person with feedback (or immediate information) of a bioelectric response enables him to learn (gain) self-control of that response. These responses traditionally have been considered involuntary and include heart rate (Scott et al., 1973a). blood pressure (Benson et al., 1971), stomach acid pH (Welgan. 1972), and electroencephalographic activity (Sterman, 1972), In the present experiments, biofeedback and its attendant technology was applied to the problem of generating heterosexual arousal in homosexual males.Frequently, in biofeedback research, reinforcement has been used in addition to feedback in attempting to teach self-control of a response. In fact, an alternate way of conceptualizing and describing the biofeedback research is in terms of operant conditioning (e.g., Weiss and Engel, 1971: Scott et al., 1973b). In one sense, however, feedback and reinforcement are inextricably confounded: the delivery or non-delivery of a reinforcer provides the S with information about the rightness or wrongness of his response and hence, binary feedback about it. Likewise, if feedback or knowledge of whether the response has reached a criterion level or not is effective in leading to a change in the response, then feedback functions as a reinforcer. Reinforcement, however, may be viewed as providing both information about the response (feedback) plus an incentive to change it in the desired direction in addition to any incentive provided by successful performance of a task. Thus, if one provides Ss with a separate, functionally defined reinforcer in such a way that no additional information about the response is conveyed, it becomes possible to detect additive effects of reinforcement over feedback effects. Such was the second purpose of this study.Several recent analogue experiments with volunteers have reported success in modifying erections through feedback and/or reinforcement. Price (1973) found that heterosexual volunteers who received analogue visual feedback as well as binary feedback, provided by a colored light once the needle had passed a pre-set criterion, showed a shorter latency to peak erection and maintained criterion erection longer than a control group receiving no feedback. Both groups were listening to erotic audio tapes. Rosen (1973) demonstrated significant suppression of tumescence in a group of heterosexual volunteers provided with response contingent signal lights. A group receiving non-contingent feedback did not show this effect. In a technical paper, Laws and Pawlowski (1973) have suggested audio feedback of tumescence as a treatment for deficits in sexual arousal.In the clinic, Harbison, Quinn and McAllister (1970), in an uncontrolled case study, reported increasing heterosexual responsiveness in homosexuals through reinforcement of erection. In one of their homosexual patients they were able, over a long series of trials, to increase erection to a heterosexual stimulus (female slide) through rewarding progressively larger responses with sips of iced lime after the patient was water deprived. In addition to the reinforcement, this S was given feedback, of sorts, in that a light was flashed for each successful trial. A second homosexual patient was similarly rewarded for maintaining progressively longer and clearer fantasies of heterosexual behavior. Since other treatments were also applied and no experimental analysis was performed, it is not possible to evaluate the effectiveness of the procedure.In the present experiment the separate effects of feedback and reinforcement to increase heterosexual arousal in homosexuals was experimentally evaluated using single case experimental design methodology (Barlow and Hersen, 1973). Since each experiment was somewhat different in design and purpose, each will be described separately. 相似文献

The space-time relationships satisfying Korte’s third law of apparent movement were studied in three experiments. The results generally confirm and extend Corbin’s conclusion that apparent movement is not a projection-level phenomenon, but one involving spatial constancy, i.e., some representation of tridimensional space. Between situations in which the stimuli were retinally matched, the time interval necessary, for apparent movement varied w~th their phenomenal separation, whether the latter was determined by the distance of stimuli from the O, deviation of sttmuli from the frontal plane, or illusory slant of the stimulus plane produced by a perspective gradient. 相似文献

Alternation of diagonal pairs of lights produced apparent movement which S could organize in either of two distinctly different ways, as instructed. The task was to detect movement of a weak probe light that either was or was not located in the path of the apparent movement, depending on the organization, stimulation being identical in the two cases. Results showed no evidence of path-specific masking. 相似文献

The relationship between the factor pattern,F, derived from fallible (containing measurement error) observations on variables and the factor pattern,F*, derived from infallible observations on variables is investigated. A widely believed relationship betweenF andF*, viz.,F*=AF whereA is a diagonal matrix containing the inverses of the square roots of the reliabilities of the variables, is shown to be false for several factor analytic techniques. Under suitable assumptions, it is shown that for Kaiser and Caffrey's alpha factor analysisF* andF are related byF*=AF. Empirical examples for which the corresponding elements ofF* andAF are equal to two decimal places are presented. The implications of the equality ofF* andAF for alpha factor analysis are discussed.I wish to acknowledge the generous assistance of Drs. Chester W. Harris and Henry F. Kaiser in the execution of the research reported in this paper. 相似文献

Worker honeybees (Apis mellifera) were reared in social isolation in complete darkness to assess the effects of experience on growth of the neuropil of the mushroom bodies (MBs) during adult life. Comparison of the volume of the MBs of 1-day-old and 7-day-old bees showed that a significant increase in volume in the MB neuropil occurred during the first week of life in bees reared under these highly deprived conditions. All regions of the MB neuropil experienced a significant increase in volume with the exception of the basal ring. Measurement of titers of juvenile hormone (JH) in a subset of bees indicated that, as in previous studies, these rearing conditions induced in some bees the endocrine state of high JH associated with foraging, but there was no correlation between JH titer and volume of MB neuropil. Treatment of another subset of dark-reared bees with the JH analog, methoprene, also had no effect of the growth of the MB neuropil. These results demonstrate that there is a phase of MB neuropil growth early in the adult life of bees that occurs independent of light or any form of social interaction. Together with previous findings showing that an increase in MB neuropil volume begins around the time that orientation flights occur and then continues throughout the phase of life devoted to foraging, these results suggest that growth of the MB neuropil in adult bees may have both experience-expectant and experience-dependent components. 相似文献

Relationships which exist among 27 Piagetian reasoning assessments and standard measures of intelligence and achievement were determined in a study conducted by Stephens, McLaughlin, Miller and Glass. Subsequently a study conducted by Humphreys and Parsons was purported to correct errors in the original designs of the Stephens et al. study. In reply Glass and Stephens note fallacies in Humphreys and Parsons reasoning and question their statement that measures of intelligence and Piagetian reasoning assessments can be used interchangeably. 相似文献

In the May/June 1997 issue of the Journal of Counseling & Development, Eugene Kelly contended that the counseling profession should integrate its theories to combine the strengths of both the humanistic and the technical orientations in the field. Kelly's recommendation is supported by previous efforts that have already advanced the field. Human Technology (HT) as devised by Robert Carkhuff integrated nondirective, psychodynamic, and behavioristic counseling modes. Extensions of HT also demonstrate the continuing growth potential in the integrative strategy. In this article, the authors discuss those endeavors to emphasize the potential contributions to be attained by integrating humanistic and technical orientations. 相似文献

The prospective effects of observed neighborhood disorder, stressful life events, and parents’ engagement in inductive reasoning
on adolescents’ depressive symptoms were examined using data collected from 777 African American families. Multilevel analyses
revealed that stressful life events experienced at age 11 predicted depressive symptoms at age 13. Furthermore, a significant
interaction between neighborhood disorder and parents’ engagement in inductive reasoning was found, indicating that parental
use of inductive reasoning was a protective factor for depressive symptoms particularly for youths living in highly disordered
neighborhoods. The importance of examining correlates of depressive symptoms from a contextual framework, focusing on individuals,
families, and neighborhood contexts, is emphasized. 相似文献

The effects of the pubertal transition on behavior problems and its interaction with family and neighborhood circumstances were examined with a sample of 867 African American children 10-12 years of age. Pubertal development status, pubertal timing, and primary caregivers' parenting behaviors were significantly related to affiliation with deviant peers and externalizing behaviors. Externalizing behavior among early-maturing children was associated positively with primary caregivers' use of harsh-inconsistent discipline and negatively with nurturant-involved parenting practices. Disadvantaged neighborhood conditions were significantly associated with deviant peer affiliation. The effect of pubertal transition varied according to family and neighborhood conditions: Early-maturing children living in disadvantaged neighborhoods were significantly more likely to affiliate with deviant peers. Early-maturing children with harsh and inconsistent parents were significantly more likely to have externalizing problems. 相似文献
