This study addressed the relative effects of repeated exposures to an austere institutional dayroom, a toy enriched dayroom, a PUSH (Play Units for the Severely Handicapped) room that contained automated stimulation devices within a physical terrain, and a modular room that contained wall mounted automated stimulation devices, on the adaptive and maladaptive freeplay behavior of six groups of institutionalized mentally retarded individuals (N = 6 per group). Group One was observed in all four settings, whereas the other five were observed in two or more of the active settings. The results indicated that (1) there were only slight differences in object-directed adaptive behavior when the three active settings were compared to the austere setting, and (2) only the higher functioning subjects (Group Five) displayed consistent individual differences on any of the measures when active settings were compared. None of the comparisons, however, revealed statistically significant effects. This study clearly demonstrates the need for active control conditions, raises questions regarding the relevance of much of the previous research, and suggests that further refinements will be necessary before environments such as those in the present study produce meaningful changes in appropriate environmental interaction in the absence of staff mediation.  相似文献

In Kohut's analysis of narcissism, the self emerges as a bipolar structure characterized by grandiosity at one pole and dependency at the other. Through appropriate developmental processes, grandiosity grows into a mature ambitiousness, and early dependencies are converted into a stable system of ideals. The present investigation predicted that sex role constructs essentially measure these two aspects of the self. Expected relationships between masculinity and grandiosity, and between femininity and dependency, were in fact obtained. Based in large part on Westin's (Self and Society, Cambridge: Cambridge University Press, 1985) analysis of Kohut's theory, synthetic, internal, external, and archaic narcissistic self styles were hypothesized to exist and to parallel the androgynous, masculine, feminine, and undifferentiated sex roles, respectively. Rough comparabilities were in fact evident between these two typologies. Factor analyses also demonstrated that narcissism and sex role measures load on factors in ways revealing the intimate ties between pathological narcissism and the failure to achieve desirable sex role characteristics.  相似文献

This investigation evaluated a method for the prospective assessment of the symptoms of premenstrual syndrome (PMS). The American Psychiatric Association has proposed a diagnostic category for PMS in the DSM-III-R entitled late-luteal phase dysphoric disorder (LLDD). The criteria for this disorder include prospective documentation of at least two symptomatic cycles. Two groups of women were studied, one group that met the DSM-III-R diagnostic criteria for LLDD and a comparison group that did not. Subjects recorded symptoms related to PMS for two menstrual cycles. A clinically significant worsening of symptoms was defined as a symptom increase during the premenstruum of greater than one standard deviation above normal. These effect sizes were then used to determine if the subject met the DSM-III-R criteria for prospective confirmation. Data analysis showed that although the LLDD group showed evidence for PMS in several symptom groups, only a minority (31%) met the requirement of prospective confirmation of significant PMS symptoms for the two cycles recorded. These results were discussed in terms of the need for prospective behavioral assessment of LLDD and the implications of these findings for past and future research.Portions of this paper were derived from the master's thesis of the first author.  相似文献

Relational and absolute stimulus learning by monkeys in a memory task.   总被引:2,自引:1,他引:1  
Three experiments showed stimulus control by either the absolute properties of probe stimuli, relational properties of the probe-list relationship, or both in a serial probe recognition memory task in which a four-item memory list was followed by a single probe (test) item. In Experiment 1, 3 rhesus monkeys received 39 to 75 repetitions of the same 24-trial stimulus sequence. Special tests showed stimulus control by the absolute properties of the probe stimuli. Retention of previous relational control was demonstrated by the good transfer (83%) to novel list and probe stimuli at the beginning of Experiment 2. During Experiment 2, control by absolute properties of the probe stimuli gradually reoccurred. Only a small measure of control by list stimuli could be detected or promoted. In Experiment 3, 4 monkeys were shown to have largely lost their ability to perform on the basis of the list-probe relationship, and were performing primarily on the basis of the absolute properties of the probe stimuli. Over the next 15 weeks, these monkeys were transferred to new stimuli at the beginning of each week. Control by the relational aspects of the task gradually returned. As transfer performance increased, control by the absolute properties of the probe stimuli was eliminated. The results are discussed in terms of stimulus control and performance strategies used by the monkeys.  相似文献

We sought to determine impacts of a pediatric primary care intervention, the Video Interaction Project, on 3-year trajectories of parenting stress related to parent–child interactions in low socioeconomic status families. A randomized controlled trial was conducted, with random assignment to one of two interventions Video Interaction Project (VIP); Building Blocks or control. As part of VIP, dyads attended one-on-one sessions with an interventionist who facilitated interactions in play and shared reading through review of videotaped parent–child interactions made on primary care visit days; learning materials and parenting pamphlets were also provided to facilitate parent–child interactions at home. Parenting stress related to parent–child interactions was assessed for VIP and Control groups at 6, 14, 24, and 36 months using the Parent–Child Dysfunctional Interaction subscale of the Parenting Stress Index—Short Form, with 378 dyads (84 %) assessed at least once. Group differences emerged at 6 months with VIP associated with lower parenting stress at three of four ages considered cross-sectionally and an 17.7 % reduction in parenting stress overall during the study period based on multi-level modeling. No age by group interaction was observed, indicating persistence of early VIP impacts. Results indicated that VIP, a preventive intervention targeting parent–child interactions, is associated with decreased parenting stress. Results therefore support the expansion of pediatric interventions such as VIP as part of a broad public health strategy to address poverty-related disparities in school-readiness.  相似文献

Although parents are increasingly involved in their college students’ academic lives, scholars have yet to investigate parents’ role in their college students’ school engagement. We hypothesized that college students’ self-regulation would mediate the relation between parent–child relationship quality and school engagement. For the 790 undergraduates who completed questionnaires online, self-regulation mediated the relation between mother–child relationship quality and school engagement for men, and an indirect effect was found for the relation between father–child relationship quality and school engagement by way of self-regulation. Therefore, parents continue to matter in promoting their college students’ academic success.  相似文献

Until recently, the literature on rhythmic ability took for granted that only humans are able to synchronize body movements to an external beat—to entrain. This assumption has been undercut by findings of beat-matching in various species of parrots and, more recently, in a sea lion, several species of primates, and possibly horses. This throws open the question of how widespread beat-matching ability is in the animal kingdom. Here we reassess the arguments and evidence for an absence of beat-matching in animals, and conclude that in fact no convincing case against beat-matching in animals has been made. Instead, such evidence as there is suggests that this capacity could be quite widespread. Furthermore, mutual entrainment of oscillations is a general principle of physical systems, both biological and nonbiological, suggesting that entrainment of motor systems by sensory systems may be a default rather than an oddity. The question then becomes, not why a few privileged species are able to beat-match, but why species do not always do so—why they vary in both spontaneous and learned beat-matching. We propose that when entrainment is not driven by fixed, mandatory connections between input and output (as in the case of, e.g., fireflies entraining to each others’ flashes), it depends on voluntary control over, and voluntary or learned coupling of, sensory and motor systems, which can paradoxically lead to apparent failures of entrainment. Among the factors that affect whether an animal will entrain are sufficient control over the motor behavior to be entrained, sufficient perceptual sophistication to extract the entraining beat from the overall sensory environment, and the current cognitive state of the animal, including attention and motivation. The extent of entrainment in the animal kingdom potentially has widespread implications, not only for understanding the roots of human dance, but also for understanding the neural and cognitive architectures of animals.  相似文献

The aim of this study was to investigate the predictive and moderating effects of HEXACO personality factors, in addition to theory of planned behavior (TPB) variables, on fruit and vegetable consumption. American college students (N = 1036) from 24 institutions were administered the TPB, HEXACO and a self-reported fruit and vegetable consumption measure. The TPB predicted 11–17% of variance in fruit and vegetable consumption, with greater variance accounted for in healthy weight compared to overweight individuals. Personality did not significantly improve the prediction of behavior above TPB constructs; however, conscientiousness was a significant incremental predictor of intention in both healthy weight and overweight/obese groups. While support was found for the TPB as an important predictor of fruit and vegetable consumption in students, little support was found for personality factors. Such findings have implications for interventions designed to target students at risk of chronic disease.  相似文献

This paper addresses a perennial question of the religious studies and, indeed, of most liberal arts classrooms: How do I get my students to read texts thoroughly and with understanding? After briefly reviewing the National Assessment of Adult Literacy (NAAL) data, I argue that what teachers desire is not just basic literacy, but fluency, which is the capacity to read analytically (and, for me, appreciatively), deploying the strategies of reading in a high process, improvisational mode. I unpack the elements and efficacy of one close reading classroom teaching practice I use, guided annotation, as a strategy for developing fluency. I argue that close analysis of a short, intentionally chosen passage with a guiding question builds towards reading fluency. Annotating short passages, singly and then in relation to other passages, with the author's and disciplinary concerns as the foci, practices the skills that build fluency. Annotation is akin to playing scales in music, repeating a baseline task of reading; working slowly and simply at first, but then with increasing speed and complexity, moving the student towards reading whole texts well.  相似文献
