Adams’ thesis is generally agreed to be linguistically compelling for simple conditionals with factual antecedent and consequent.
We propose a derivation of Adams’ thesis from the Lewis-Kratzer analysis of if-clauses as domain restrictors, applied to probability
operators. We argue that Lewis’s triviality result may be seen as a result of inexpressibility of the kind familiar in generalized
quantifier theory. Some implications of the Lewis-Kratzer analysis are presented concerning the assignment of probabilities
to compounds of conditionals. 相似文献

This study involved the translation, cultural adaptation and validation of the Athletic Coping Skills Inventory (ACSI-28) for a Spanish-speaking sport environment. The sample was made up of 1,253 Spanish athletes, 967 males and 286 females. Confirmatory factor analysis (CFA) showed that the 7-factor structure found in the English version was replicated in the Spanish translation in both males and females. Likewise, the reliability coefficients were similar to those of the English version, with values exceeding .80 for the total score. Several of the subscales correlated positively with sports experience and performance level. The Spanish version of the ACSI-28 thus maintains the factor structure of the original and exhibits similar psychometric properties. Consequently, it can reliably be applied to Spanish-speaking athletes for research and evaluation purposes. 相似文献

Evidence suggests that mind wandering is a frequent accompaniment to an unhappy mood. Building on such work, two laboratory experiments used mood induction to assess whether the greater frequency of mind wandering in a low mood is also accompanied by a shift towards a focus on events from the past. Experiment 1 induced moods via video and induction of an unhappy mood was associated with a greater tendency for past-related mind wandering as measured by a post-task questionnaire. In Experiment 2, negative and positive moods were induced in a group of participants using the Velten mood-induction procedure and the temporal focus of mind wandering was measured using experience sampling probes. Analyses indicated that induction of an unhappy mood led to an increase in past-related mind wandering and the magnitude of this change increased with scores on a measure of depressive symptoms. Together these experiments suggest that when the mind wanders in an unhappy mood it is drawn to events from its past. 相似文献

Medication rates in behaviorally disordered children and youth have greatly increased to current high levels and are very controversial. This study examined changes in psychotropic medication use, levels of behavioral disturbance, and use of personal restraint and seclusion in a population of youth with serious behavioral disorders receiving medically directed cognitive-behavioral treatment in an intensive residential setting. The hypothesis was that there would be significant reductions in medication rates, without the unintended consequences of increased rates of problem behavior or offsetting increases in the use of seclusion or personal restraint. Results showed significant reductions in both the number of youth on medication and the average number of psychotropic medications during the residential stay. There were also significant reductions in behavioral disturbance, seclusions, and personal restraints. These results demonstrate that psychotropic medication can be significantly reduced without increases in problem behavior or the use of seclusions or personal restraints. We conclude that it is possible to significantly reduce psychotropic medication rates to far more conservative levels within the context of a clinically directed cognitive-behavioral treatment milieu. 相似文献

Research has shown that between 40 and 98 % of youth entering residential treatment are taking at least one psychotropic medication and that psychotropic medication management is often an integral component of treatment in residential settings. To determine physician opinion about the difficulty of managing psychotropic medications for youth in residential treatment and to determine the resources that are used in the process, a survey study was conducted. Overall, physicians indicated that youth involved in residential settings were much more complex than those in traditional outpatient settings, due to multiple mental health diagnoses, polypharmacy, and unknown treatment histories. They also reported that many existing resources are not applicable to youth, particularly those in residential settings, and that they are difficult to read and interpret. 相似文献

Two experiments investigated whether separate sets of objects viewed in the same environment but from different views were encoded as a single integrated representation or maintained as distinct representations. Participants viewed two circular layouts of objects that were placed around them in a round (Experiment 1) or a square (Experiment 2) room and were later tested on perspective-taking trials requiring retrieval of either one layout (within-layout trials) or both layouts (between-layout trials). Results from Experiment 1 indicated that participants did not integrate the two layouts into a single representation. Imagined perspective taking was more efficient on within- than on between-layout trials. Furthermore, performance for within-layout trials was best from the perspective that each layout was studied. Results from Experiment 2 indicated that the stable environmental reference frame provided by the square room caused many, but not all, participants to integrate all locations within a common representation. Participants who integrated performed equally well for within-layout and between-layout judgments and also represented both layouts using a common reference frame. Overall, these findings highlight the flexibility of organizing information in spatial memory. 相似文献

The behavioral uncertainty response has grounded the study of animal metacognition and influenced the study of human psychophysics. However, the interpretation of this response is debated—especially whether it is a behavioral index of metacognition. The authors advanced this interpretation using the dissociative technique of response deadlines. Uncertainty responding, if it is higher level or metacognitive, should depend on a slower, more controlled decisional process and be more vulnerable to time constraints. Humans performed sparse–uncertain–dense or sparse–middle–dense discriminations in which, respectively, they could decline difficult trials or positively identify middle stimuli. Uncertainty responses were sharply and selectively reduced under a decision deadline, as compared to primary perceptual responses (i.e., “sparse,” “middle,” and “dense” responses). This dissociation suggests that the uncertainty response does reflect a higher-level, decisional response. It grants the uncertainty response a distinctive psychological role in its task and encourages an interpretation of this response as an elemental behavioral index of uncertainty that deserves continuing research. 相似文献

When we plan sequences of actions, we must hold some elements of the sequence in working memory (WM) while we execute others. Research shows that execution of an action can be delayed if it partly overlaps (vs. does not overlap) with another action plan maintained in WM (partial repetition cost). However, it is not known whether all features of the action maintained in WM interfere equally with current actions. Most serial models of memory and action assume that interference will be equal, because all action features in the sequence should be activated to an equal degree in parallel; others assume that action features earlier in the sequence will interfere more than those later in the sequence, because earlier features will be more active. Using a partial repetition paradigm, this study examined whether serial position of action features in action sequences maintained in WM have an influence on current actions. Two stimulus events occurred in a sequence, and participants planned and maintained an action sequence to the first event (action A) in WM while executing a speeded response to the second event (action B). Results showed delayed execution of action B when it matched the first feature in the action A sequence (partial repetition cost), but not when it matched the last feature. These findings suggest that serial order is represented in the action plan prior to response execution, consistent with models that assume that serial order is represented by a primacy gradient of parallel feature activation prior to action execution. 相似文献

False‐positive outcomes of functional analyses exist when exposure to the consequences in a condition strengthens a relation that did not previously exist. Two functional analyses (aggression and spitting) were conducted with a child with an intellectual disability. High rates of problem behavior occurred immediately in the attention condition of the functional analysis across response topographies, suggesting a clear functional response class. However, rates of aggression and spitting increased in the demand condition, following the initial block of sessions, indicating the possible creation of a novel contingent relation for spitting.

Although efficacious psychological treatments for internalizing disorders are now well established for school-aged children, until recently there have regrettably been limited empirical efforts to clarify indicated psychological intervention methods for the treatment of mood and anxiety disorders presenting in early childhood. Young children lack many of the developmental capacities required to effectively participate in established treatments for mood and anxiety problems presenting in older children, making simple downward extensions of these treatments for the management of preschool internalizing problems misguided. In recent years, a number of research groups have successfully adapted and modified parent–child interaction therapy (PCIT), originally developed to treat externalizing problems in young children, to treat various early internalizing problems with a set of neighboring protocols. As in traditional PCIT, these extensions target child symptoms by directly reshaping parent–child interaction patterns associated with the maintenance of symptoms. The present review outlines this emerging set of novel PCIT adaptations and modifications for mood and anxiety problems in young children and reviews preliminary evidence supporting their use. Specifically, we cover (a) PCIT for early separation anxiety disorder; (b) the PCIT-CALM (Coaching Approach behavior and Leading by Modeling) Program for the full range of early anxiety disorders; (c) the group Turtle Program for behavioral inhibition; and (d) the PCIT-ED (Emotional Development) Program for preschool depression. In addition, emerging PCIT-related protocols in need of empirical attention—such as the PCIT-SM (selective mutism) Program for young children with SM—are also considered. Implications of these protocols are discussed with regard to their unique potential to address the clinical needs of young children with internalizing problems. Obstacles to broad dissemination are addressed, and we consider potential solutions, including modular treatment formats and innovative applications of technology. 相似文献
