Rats were allowed to forage in a simulated natural environment made up of eight food sources (patches) each containing a fixed number of pellets. Two of the eight contained an extra supply of peanuts. The peanut patches were signaled by an olfactory/visual cue located at the bottom of the ladder leading to the patch. In successive phases the number of sessions per day, height of the patches, and availability of peanuts were manipulated. Subjects showed evidence of discrimination learning under these conditions, although the degree of discriminatory behavior varied as a function of environmental manipulations. Assessment of behavior within foraging sessions showed that subjects systematically changed their patterns of utilization of patches across time. Sampling or exploration, as well as food reinforcement, seem implicated in these results. 相似文献

The effects of a graduated prompting treatment procedure were analyzed in three phases of an experiment on the training and generalization of reaching-grasp responding in 2- to 4-year-old blind, severely or profoundly retarded children. In Phase 1, we used a multiple-baseline across-subjects design to investigate the effectiveness of the treatment on midline reach-grasp responding. In Phase 2, we used a reversal design to investigate the effects of repeated implementations and withdrawals of the treatment. In both phases, generalization to right and left positions was measured. In Phase 3, in a multiple-baseline across-responses design, the treatment was implemented in right and left positions. Also in Phase 3, shift of stimulus control from toy-sound to verbal instructions was measured. The results showed that (a) the graduated prompting procedure was effective in training reach-grasp responding in all three children; (b) for one child, the effects were durable over repeated applications of the treatment procedure, but were not maintained during withdrawals; (c) for another child, the treatment procedure was effective in teaching reach-grasp responding in all three positions; and (d) for the same child, training of reach-grasp responding generalized to toys presented without sound, given only the verbal instruction. 相似文献

New theological understanding can emerge with the advancement of scientific knowledge and the use of new concepts, or older concepts in new ways. Here, the authors present a proposal to extend the concept of “rescue and recovery” found in the United Nations Law of the High Seas, off-world and within a broader purview of other intelligent and self-aware species that humans may someday encounter. The notion of a morality that extends to off-world species is not new, but in this analysis, rescue and recovery become an imperative when any intelligent and self-aware species is in harm's way. Rescue and recovery encompass a necessary action component except perhaps in those cases where rescuers are in danger. The authors explore three biblical examples of rescue and recovery to derive a fundamental meaning of the concept. 相似文献

This piece brings into critical conversation Christian resurrection hope, virtual versions of transhumanism, and intellectual disability and demonstrates that Christian resurrection provides a more cogent hope for people with severe intellectual disabilities than transhumanism. I argue that transhumanist virtual futures are theologically problematic, as bodily resurrection is neither required nor desirable. It is particularly problematic for people with severe intellectual disabilities given the way they would be excluded from these futures. Disability theology also raises issues with the traditional notions of “healing” in the resurrection and the implications for the value and identity of persons with intellectual disabilities. Starting with these problems, I explore the nature of Christian hope, noting the inadequacies of a virtual transhumanist future with respect to both resurrection faith and intellectual disability, and address how resurrection hope can account for issues raised in disability theology, and so properly include people with intellectual disabilities. 相似文献

Preventive health practices have been crucial to mitigating viral spread during the COVID-19 pandemic. In two studies, we examined whether intellectual humility—openness to one's existing knowledge being inaccurate—related to greater engagement in preventive health practices (social distancing, handwashing, mask-wearing). In Study 1, we found that intellectually humble people were more likely to engage in COVID-19 preventive practices. Additionally, this link was driven by intellectually humble people's tendency to adopt information from data-driven sources (e.g., medical experts) and greater feelings of responsibility over the outcomes of COVID-19. In Study 2, we found support for these relationships over time (2 weeks). Additionally, Study 2 showed that the link between intellectual humility and preventive practices was driven by a greater tendency to adopt data-driven information when encountering it, rather than actively seeking out such information. These findings reveal the promising role of intellectual humility in making well-informed decisions during public health crises. 相似文献

The Comprehensive Ability Battery (CAB) was used to assess 18 primary mental abilities in 53 white, male prison inmates for whom highly reliable ratings of psychopathy were available. None of the correlations between ratings of psychopathy and scores on the CAB tests was significant, and the overall pattern or structure of abilities was the same for inmates with low and high ratings of psychopathy. The possibility is raised that the personality characteristics of psychopaths make them appear to be brighter and more creative than they actually are. Compared with norms for male high school students, the inmates as a group generally performed well, falling near the 50th percentile on 11 of the tests. The inmates performed significantly better than the normative sample on tests of verbal ability, esthetic judgment, aiming, and representational drawing, and significantly worse on tests of ideational fluency, spontaneous flexibility, and word fluency.This research was supported by Grant MT-4511 from the Medical Research Council of Canada. 相似文献

We applied a narrative identity approach to the study of romantic infidelity. In Study 1, participants provided narratives of the moment they discovered their partners' infidelity. In Study 2, participants were prompted for narratives of their unfaithful actions. In both studies, measures of personality traits, forgiveness, empathy, and self‐esteem were administered. Narratives were coded for themes of redemption (bad beginnings, positive endings) and exploration (engaging with the experience's emotional implications). After controlling for relevant covariates (e.g., story length), participants who formed redemptive stories of their partner's infidelity evinced higher levels of forgiveness and lower levels of empathy (Study 1), whereas participants who disclosed redemptive stories about their own infidelity demonstrated decreased forgiveness (Study 2). Across studies, exploratory narratives corresponded positively with conscientiousness. 相似文献

Objectives: This systematic review aimed to critically appraise the literature on the efficacy and effectiveness of psychoanalysis, psychoanalytic and psychodynamic psychotherapy in adults with intellectual and developmental disabilities (IDD). Method: A systematic search of electronic databases was carried out. The methodological quality of the studies was assessed using a quality assessment tool and comparisons were made with a review of the quality of research on the effectiveness of cognitive behavioural therapy (CBT) for people with IDD. Results: The search yielded 13 papers which provided evidence for the effectiveness but not efficacy of psychoanalytic and psychodynamic psychotherapy; but none were found for psychoanalysis. The quality of the research was generally poor compared to the current research on the effectiveness of CBT. Conclusions: Positive outcomes have been indicated for psychoanalytic and psychodynamic psychotherapy with people with IDD. Larger scale, more controlled research is necessary to advance the evidence base. 相似文献

This paper explores the historic philosophical contributions ofMill and Marx toward a comprehensive conception of intellectual freedomas a basic educational entitlement. In a perhaps surprising confluence,Marx's theory of a material base for freedom of thought is then extendedin a discussion of contemporary freedoms including, importantly,academic freedom and its implication for teaching, the profession andits training. 相似文献

Clinical signs of damage to the egocentric reference system range from the inability to detect stimuli in the real environment to a defect in recovering items from an internal representation. Despite clinical dissociations, current interpretations consider all symptoms as due to a single perturbation, differentially expressed according to the medium explored (perceptual or representational). We propose an alternative account based on the functional distinction between two separate egocentric mechanisms: one allowing construction of the immediate point of view, the other extracting a required perspective within a mental representation. Support to this claim comes from recent results in the domain of navigation, showing that separate cognitive mechanisms maintain the egocentric reference when actively exploring the visual space as opposed to moving according to an internal map. These mechanisms likely follow separate developmental pathways, seemingly depend on distinct neural pathways and are used independently by healthy adults, reflecting task demands and individual cognitive style. Implications for spatial cognition and social skills are discussed. 相似文献
