Two case studies were conducted to investigate the utility of curriculum-based measurement of math and reading for evaluating the effects of methylphenidate on the academic performance of 2 students diagnosed with attention deficit hyperactivity disorder. Following baseline measurement, double-blind placebo-controlled procedures were employed to evaluate each student's response to three levels (5 mg, 10 mg, and 15 mg) of the medication. Results of the first study suggest that the curriculum-based measures were sensitive indicators of the student's response to medication. This finding was replicated in the second study. In the second study, when the student's follow-up dose of medication was based on trial-phase data, follow-up performance was improved compared to baseline performance. These case studies suggest that further research is warranted on the utility of curriculum-based measurements for monitoring and evaluating stimulant medication interventions with children with this disorder. 相似文献

The Adaptive Counseling and Therapy (ACT: Howard, Nance, & Myers, 1986) model was used to predict who would benefit from computerized career counseling. Specifically, clients who had more stable goals and aspirations and more defensive independence were expected to derive more benefit from computerized career counseling, an intervention that provides low levels of direction and support. A total of 54 clients who came to the Career Planning and Placement Center seeking career assistance were referred to the System for Interactive Guidance and Information PLUS (SIGI-PLUS). As hypothesized, clients with more stable goals had the greatest gains in vocational identity. Additionally, clients who showed more defensive independence were more satisfied with the SIGI-PLUS treatment. Implications, limitations, and suggestions for future research are discussed. 相似文献

In this study, we observed and linguistically analyzed the verbal behavior of six manic subjects, looking specifically for those linguistic capacities which were intact and for those which were disrupted. From interviews and tape-recordings of manic subjects in both analytic-protocol and discourse situations, we observed a preservation of basic speech capacities, including the ability to comprehend and generate grammatical sentences and to utilize highly complex linguistic transformations. We noted, however, a disruption in the ability to properly utilize ellipsis and semantic (discourse) anaphora such that manic subjects did not maintain a meaningful progression of thought in discourse. 相似文献

Working memory (WM) impairments are reported to occur in patients with Parkinson's disease (PD). However, the mechanisms are unclear. Here, we investigate several putative factors that might drive poor performance, by examining the precision of recall, the order in which items are recalled and whether memories are corrupted by random guessing (attentional lapses). We used two separate tasks that examined the quality of WM recall under different loads and retention periods, as well as a traditional digit span test. Firstly, on a simple measure of WM recall, where patients were asked to reproduce the orientation of a centrally presented arrow, overall recall was not significantly impaired. However, there was some evidence for increased guessing (attentional lapses). On a new analogue version of the Corsi-span task, where participants had to reproduce on a touchscreen the exact spatial pattern of presented stimuli in the order and locations in which they appeared, there was a reduction in the precision of spatial WM at higher loads. This deficit was due to misremembering item order. At the highest load, there was reduced recall precision, whereas increased guessing was only observed at intermediate set sizes. Finally, PD patients had impaired backward, but not forward, digit spans. Overall, these results reveal the task- and load-dependent nature of WM deficits in PD. On simple low-load tasks, attentional lapses predominate, whereas at higher loads, in the spatial domain, the corruption of mnemonic information—both order item and precision—emerge as the main driver of impairment. 相似文献

In response to several problems identified in the primary and secondary literature, this article advances an “expressive” conception of action and agency that (i) is consistent with the metaphysics of Deleuze and Guattari’s A Thousand Plateaus, (ii) can underpin the ethical dimensions of this text, and (iii) meets some of the general requirements of a philosophy of action. This conception will be distinguished from standard theories in the philosophy of action, to the extent that these latter conceptualize and explain action with reference to intentions taken as psychological causes that are specifiable in advance and independently of the resultant activity. But it will also be distinguished from commentaries that, after rightly identifying the standard conception of intentional action as incompatible with Deleuze and Guattari’s metaphysics, fail to substitute a viable conception of action and agency in its stead. In short, drawing on a notion of expression, this article will advance a conception of intentions that does not treat them as prior and independently specifiable causes of action, but rather as “immanent” causes whose intelligible content is inseparable from—that is, dynamically assembled and specified within—the ecologically and socially situated, temporally extended and reality-transforming actions they animate. 相似文献

Naturalness is a significant driver of food-related choices. However, there is scarce knowledge of how textual cues could be utilised to enhance the effectiveness of naturalness claims. Drawn from construal level theory, we attempted to examine how different methods of framing naturalness affect consumers in online vs. offline shopping contexts. Study 1 employed a 2 (abstract vs. concrete) × 2 (online vs. offline) experiment with 127 respondents and demonstrated that concrete framing heightens positive attitudes via increased perceived concreteness of the message, especially in offline shopping situations. Study 2 employed a 4 (abstract vs. control vs. concrete without mentioning natural vs. concrete mentioning natural) × 2 (online vs. offline) experiment with 173 respondents and replicated findings from Study 1. Furthermore, Study 2 ruled out alternative explanations of message authenticity, transparency and credibility and indicated that the effect of message framings is truly driven by the congruency between consumers' construal level and message framings. Interestingly, no significant effect of abstractly framed naturalness claims was observed in online shopping situations, contradicting existing studies. This suggests that other psychological mechanisms may interplay and hinder the effectiveness of abstract framing in our study. Taken together, the current research demonstrate that consumers' mental representation varies across shopping platforms and how it affects their evaluation of different methods of message framing. 相似文献

Infants and toddlers discriminate amount: are they measuring? 总被引:1,自引:0,他引:1
Four experiments that show an early ability to encode and retain information about extent are presented. We found that infants discriminate between the heights of dowels in a habituation task. We also found that toddlers discriminate between heights on a choice task in which a target dowel is presented and removed and they then choose between the target and a foil. Until 4 years of age, however, discrimination occurs only in the presence of a perceptually salient standard. Adults do not require a perceptually present standard; they can assess extent across temporal or spatial gaps by imposing a standard (measure). The present findings indicate that infants and toddlers do not possess an adult ability to establish extent, but that they do possess a skill that provides a start point for this important intellectual achievement. 相似文献

Five experiments demonstrate how potential moral stigma leads people to underplay their susceptibility to sexually transmitted diseases (STDs) and dampens their interest in getting tested. After adding unprotected sex to a list of otherwise innocuous possible vectors for a disease, the authors found that infected people were perceived to be less moral (Experiment 1a), and individuals believed that if they had the disease, others would see them as less moral too (Experiment 1b). Adding this stigmatized vector also reduced reported testing intentions (Experiment 2) and perceived risk of exposure (Experiment 3)--a disjunction fallacy because adding a potential cause reduced estimated likelihood, in violation of basic probability rules. Finally, the authors replicated the effect in a computer virus analog (Experiment 4) and showed that it did not result from simply knowing that one has not engaged in the stigmatized behavior. Results suggest that avoidance of potential stigma can have dramatic health consequences, both for an individual's health decision and for health policy. 相似文献

Entorhinal cortex lesions induce significant reorganization of several homotypic and heterotypic inputs to the hippocampus. This investigation determined whether surviving heterotypic inputs after bilateral entorhinal lesions would support the acquisition of a learned alternation task. Rats with entorhinal lesions or sham operations were trained to acquire a spatial alternation task. Although the sham-operated rats acquired the task within about 3 weeks postsurgery, rats with bilateral entorhinal lesions failed to learn the task after 12 consecutive weeks of training despite heterotypic sprouting of the cholinergic septodentate pathway and the expansion of the commissural/associational fiber plexus within the dentate gyrus. Thus, heterotypic sprouting failed to ameliorate significantly the effects of bilateral entorhinal lesions. Rather, entorhinal lesions produced a persistent impairment of spatial memory, characterized by a mixture of random error production and perseverative responding. 相似文献
