The hallmark of amnesia is poor explicit long‐term memory along with normal short‐term memory. It is often stated that information encountered by amnesic patients is forgotten within 1 minute of presentation. However, previous work has not distinguished between forgetting as a function of time versus the interfering material occupying that time. We show that there is a marked benefit of reduced interference in amnesic patients with mild cognitive impairment (MCI), a condition that is characterised by anterograde amnesia in the absence of other neuropsychological deficits and carries an increased risk for Alzheimer's disease. The result suggests that long‐term memory is encoded in these patients to a greater extent than had been realised but that their memory is highly vulnerable to interference. 相似文献

Bicolored objects are retained in visual short-term memory (VSTM) less efficiently than unicolored objects. This is unlike
shape–color combinations, whose retention in VSTM does not differ from that observed for shapes only. It is debated whether
this is due to a lack of color integration and whether this may reflect the function of separate memory mechanisms. Participants
judged whether the colors of bicolored objects (each with an external and an internalcolor) were the same or different across
two consecutive screens. Colors had to be remembered either individually or in combination. In Experiment 1, external colors in the combined colors condition were remembered better than the internal colors, and performance for both
was worse than that in the individual colors condition. The lack of color integration observed in Experiment 1 was further supported by a reduced capacity of VSTM to retain color combinations, relative to individual colors (Experiment 2). An additional account was found in Experiment 3, which showed spared color–color binding in the presence of impaired shape–color binding in a brain-damaged patient, thus
suggesting that these two memory mechanisms are different. 相似文献

Age effects on dual-task costs were examined in healthy adults (Exp. 1) and in typically developing children (Exp. 2). In both experiments, individual differences in performance on the single-task components were titrated so that any age
differences in dual-task costs could not be attributed to differences in single-task performance. Dual-task costs were found,
but there were no age-related differences in these costs in older relative to younger adults, in 7-year-old relative to 9-year-old
children, or across all four age groups. The results from these experiments suggest that previously reported age differences
in dual-task costs, in both healthy ageing and child development, may be due to a failure to adequately equate single-task
difficulty. 相似文献

Alzheimer's disease (AD) is the 3rd most costly disease and the leading cause of dementia. It can linger for many years, but ultimately is fatal, the 6th leading cause of death. Alzheimer's disease (AD) is fatal and affected individuals can sometimes linger many years. Current treatments are palliative and transient, not disease modifying. This article reviews progress in the search to identify the primary AD-causing toxins. We summarize the shift from an initial focus on amyloid plaques to the contemporary concept that AD memory failure is caused by small soluble oligomers of the Aβ peptide, toxins that target and disrupt particular synapses. Evidence is presented that links Aβ oligomers to pathogenesis in animal models and humans, with reference to seminal discoveries from cell biology and new ideas concerning pathogenic mechanisms, including relationships to diabetes and Fragile X. These findings have established the oligomer hypothesis as a new molecular basis for the cause, diagnosis, and treatment of AD. 相似文献

Play signals are viewed as important means by which animals inform each other that bites, strikes, and throws that occur during play fighting are indeed playful rather than serious. One such signal is the open mouth play face that is common in primates and many other mammals. Unfortunately, as most play fighting involves biting, it can be ambiguous as to whether any instance of opening the mouth is performed to communicate playful intent or is simply a preparation for biting. In this study, open mouths co-occurring with the bared-teeth display (teeth-baring) in Tonkean macaques were used to assess the context in which facial gestures only relevant for signaling (i.e., teeth-baring is not necessary for biting) are used during play. Two predictions arising from the hypothesis that play signals are used to facilitate playful contact were tested: that the open mouth with teeth-baring should (1) be most frequent preceding contact, and (2) that it should be performed most often when bites are directed at orientations that is visible to the recipient. The data only partially support these predictions. The open mouth with teeth-baring is also frequently used when a monkey withdraws from playful contact. Moreover, it is associated with bites to body targets, such as the rump, that offer little prospect for detection by the recipient; this supports the possibility that play signals may sometimes be emitted not to communicate with the partner but with the performer itself. Thus, play signals serve multiple functions during play fighting. 相似文献

We report the results of an experiment investigating conditional inferences from conditional assertions such as 'Juan won't go to León unless Nuria goes to Madrid' and 'Either Nuria goes to Madrid or Juan won't go to León'. This experiment addresses Dancygier's claims about the semantics of 'unless' by examining inferential endorsements of 'not-A unless B' and 'Either B or not-A' in the canonical order, presenting the categorical premise after the conditional assertions, and in the inverse order, presenting the categorical premise before the conditional assertions. The results of the experiment confirm that the representation of 'unless' includes two possibilities, although as Dancygier holds one of the possibilities may not be complete. The implications of the results are discussed in the context of the strategic nature of conditional reasoning and recent convergent theories of linguistic processing. 相似文献

We use the term Quixoteism to refer to a new social motive. The characterization of this motive deals with two aspects: the definition of the ultimate goal (i.e., to increase the welfare of the world) and the proposal of a process that activates it (i.e., a transcendental-change orientation). Three studies were conducted to test this characterization. In Study 1 we developed an empirical measure of the transcendental-change orientation. The participants in Studies 2 and 3 were presented with a need situation. Results showed that the centrality of such an orientation was directly related to an interpretation consistent with the ultimate goal of Quixoteism (Study 2), and that its salience increases the likelihood of performing a high-cost prosocial behavior (Study 3). 相似文献

This paper provides an analysis of a basic assumption grounding the clinical research: the ontological autonomy of psychotherapy—based
on the idea that the clinical exchange is sufficiently distinguished from other social objects (i.e. exchange between teacher
and pupils, or between buyer and seller, or interaction during dinner, and so forth). A criticism of such an assumption is
discussed together with the proposal of a different epistemological interpretation, based on the distinction between communicative
dynamics and the process of psychotherapy—psychotherapy is a goal-oriented process based on the general dynamics of human
communication. Theoretical and methodological implications are drawn from such a view: It allows further sources of knowledge
to be integrated within clinical research (i.e. those coming from other domains of analysis of human communication); it also
enables a more abstract definition of the psychotherapy process to be developed, leading to innovative views of classical
critical issues, like the specific-nonspecific debate. The final part of the paper is devoted to presenting a model of human
communication—the Semiotic Dialogical Dialectic Theory–which is meant as the framework for the analysis of psychotherapy. 相似文献

The aim of this study was to examine physiological, perceptual, and affective responses during self-paced walking for three age groups. 66 adult women were assigned into three groups by age: 20-25 yr. (n=22), 30-35 yr. (n=22), and 40-45 yr. (n=22). Each participant completed a maximal exercise test and a 20-min. bout of walking at a self-selected pace. The preferred walking speed was similar for all age groups, whereas physiological responses relative to maximal and ventilatory threshold values were greater in the 40-45 yr. group than the other two groups. Nevertheless, perceptual and affective responses were similar for all age groups. These findings suggest that physiological responses, but not perceptual and affective responses, of sedentary women are associated with age during walking at a self-selected pace. 相似文献

The present study focuses on the interplay of emotion‐regulation ability and perceived workplace social support as predictors of job satisfaction and happiness in a Spanish multi‐occupational sample. A total of 494 working adults (39.4% females) took part in this study. Emotion‐regulation ability and perceived support from colleagues and supervisors were positively associated. In addition, emotion‐regulation ability and perceived support from colleagues and supervisors showed positive associations with job satisfaction and happiness. Furthermore, considering results from moderation analyses, when low levels of perceived workplace social support were reported, the relationship between emotion regulation and both job satisfaction and happiness was stronger than in cases of higher perceived workplace support. In line with previous studies, these findings suggest that training in emotion regulation abilities may take into consideration the potential moderating role of job characteristics such as support from colleagues and supervisors. Finally, theoretical and practical implications of the joint study of these factors in line with the Job Demands‐Resources model and the Emotional Intelligence framework are discussed. 相似文献
