Although previous studies had shown that classical predifferentiation of green (CS-j and red (CS+) cues enabled them to facilitate tracking performance when used as supplementary indicators of correct and incorrect responses respectively, the studies were inconclusive concerning specific conditional properties versus nonspecific arousal consequences of the cues. A sample of 108 Ss was exposed to the same predifferentiation procedure, but then were subgrouped in terms of the kind of feedback signal received in tracking (no signal, red only, green only, both signals). A nonspecificity theory predicts subgroup equality of tracking performances while specificity theory predicts the dependence of performance level on the kind of signal received. Results corroborated previous findings and the view that tracking effects were reasonably attributable to the transfer of specific stimulus functions generated in the differentiation trials. 相似文献

This study demonstrated that motor skill proficiency ratings are constrained by the same order parameter dynamics that constrain action production and action perception processes. Participants produced rhythmic actions simulated by an animated stick figure of the human arm. The primary finding was that participants’ proficiency ratings covaried most with relative phase (φ) variability compared to mean relative phase. In-phase (φ = 0°) was produced with the least variability and received the highest proficiency rating, whereas the patterns φ = ±150° were attempted with the most variability and received the lowest proficiency ratings. A temporal delay in attempting to produce the animated pattern had a large impact on produced relative phase, yet had little impact on the proficiency ratings. Proprioceptive processes provide individuals information on motor skill proficiency. The lead or lag motion of the hand to forearm segment of the animated arm was identified consistently through visual processes and revealed asymmetries in the mapping of visual input to motor output. The results are consistent with concepts from the dynamic pattern theory of coordination and are discussed with regard to relative phase as an informational variable that constraints the perception-action system across many levels. 相似文献

We have fabricated a molecular organic light-emitting device comprising indium–tin oxide/a molecular organic layer/aluminum in which the organic layer is a green fluorescent protein. The device exhibits peak external quantum and power efficiencies of 8?±?0.2% and 13?±?0.7?lm?W???1 at a current of J?=?1.5?A?m?2, respectively. In addition, the turn-on voltage is 2.5?V for 1?cd?m?2 and the maximum luminance achieved is 1275?cd?m?2. This good performance can be explained by the presence of singlet-excited states, leading to a high internal efficiency. 相似文献

ABSTRACTMindfulness-based cognitive therapy (MBCT) appears to be a promising intervention for the prevention of relapse in major depressive disorder, but its efficacy in patients with current depressive symptoms is less clear. Randomized clinical trials of MBCT for adult patients with current depressive symptoms were included (k = 13, N = 1046). Comparison conditions were coded based on whether they were intended to be therapeutic (specific active controls) or not (non-specific controls). MBCT was superior to non-specific controls at post-treatment (k = 10, d = 0.71, 95% confidence interval [CI] [0.47, 0.96]), although not at longest follow-up (k = 2, d = 1.47, [?0.71, 3.65], mean follow-up = 5.70 months across all studies with follow-up). MBCT did not differ from other active therapies at post-treatment (k = 6, d = 0.002, [?0.43, 0.44]) and longest follow-up (k = 4, d = 0.26, [?0.24, 0.75]). There was some evidence that studies with higher methodological quality showed smaller effects at post-treatment, but no evidence that effects varied by inclusion criterion. The impact of publication bias appeared minimal. MBCT seems to be efficacious for samples with current depressive symptoms at post-treatment, although a limited number of studies tested the long-term effects of this therapy. 相似文献

Abstract The current pilot study aimed at providing an initial assessment of how anxiety influences police officers’ shooting behavior. Seven police officers participated and completed an identical shooting exercise under two experimental conditions: low anxiety, against a non-threatening opponent, and high anxiety (HA), against a threatening opponent who occasionally shot back using colored soap cartridges. Measurements included shooting accuracy, movement times, head/body orientation, and blink behavior. Results showed that under HA, shooting accuracy decreased. Underlying this degradation of performance, participants acted faster and made themselves smaller to reduce the chance of being hit. Furthermore, they blinked more often, leading to increases in the amount of time participants had their eyes closed. Findings provide support for attentional control theory, hereby also pointing to possible interventions to improve police officers’ shooting performance under pressure. 相似文献

This paper aims at introducing some of the central aspects of the evolution that brief strategic therapy has undergone at the Centro di Terapia Strategica of Arezzo, Italy, towards advanced therapeutic strategies which differ from the original Palo Alto model. (Fisch, Weakland, &; Segal, 1982; Watzlawick, 1978; Watzlawick, Beavin, &; Jackson, 1967; Watzlawick, Weakland, &; Fisch, 1974). We will focus on how the concept of self-deception is central to the formation and the persistence of psychological disorders; and how the usage of non-ordinary logics and the understanding of the individual's perceptive-reactive system are of key importance in unravelling such disorders, allowing the therapist to guide the patient towards an efficacious and efficient solution. Rather than attempting to describe and enlist the theoretical corpus that underlies brief strategic therapy, we have chosen to exemplify some focal concepts that connect theory to practice, and vice versa, by presenting the outline of some therapeutic protocols devised for solving eating disorders which can be specifically tailored for each individual patient. 相似文献

中学生厌学心理及其干预与学习效率的相关研究 总被引:17,自引:1,他引:16
本研究旨在考察两个问题:1.心理咨询是否是改变中学生厌学心理的有效途径,如果是,它能够在多大程度上改变厌学心理;2.厌学心理的改善能否有效提高中学生学习效率。本实验用问卷调查法从183名中学生中筛选出有厌学心理的学生24名。运用个体心理咨询、团体心理咨询等手段对这24名学生进行为期4个月干预、结果表明:心理咨询能够有效且明显地改善厌学心理。但要完全消除厌学心理则还需要辅以其他干预手段;随着学生厌学心理的改善,其学习效率也相应有了明显的提高。 相似文献

Prior research (cf. Soman & Shi, 2001 ) has shown that obstacles and periods of low progress in an experience reduce the evaluation of that experience. In this research, we propose that the temporal distance between the obstacle and the time of making the evaluation moderates the effect of the obstacle. Consequently, an early (late) obstacle reduces prospective (retrospective) evaluation more significantly than a late (early) obstacle. In two experiments, we find support for this temporal proximity hypothesis. Further, differences between prospective and retrospective evaluations disappeared when the data were analyzed in terms of temporal distance, suggesting that the judgment policies underlying prospective and retrospective evaluations were the same. We also show that it is possible to create pairs of paths such that one of the two paths would be preferred when viewed in prospect, but the other path might be preferred in retrospect.

Abstract: A variety of strategies have been used to oppose the influential Humean thesis that all of an agent's reasons for action are provided by the agent's current wants. Among these strategies is the attempt to show that it is a conceptual truth that reasons for action are non‐relative. I introduce the notion of a basic reason‐giving consideration and show that the non‐relativity thesis can be understood as a corollary of the more fundamental thesis that basic reason‐giving considerations are generalizable. I then consider the relationship between the generalizability thesis and the Humean thesis that all of an agent's reasons for action are provided by the agent's current wants. I argue that, contrary to a common assumption, there is a subtle and clearly motivated version of the Humean thesis that does not deny, and so is not threatened by, the generalizability thesis. 相似文献
