Computer-based interventions are being used more in the classroom. Student responses to these interventions often contribute to decisions making regarding important outcomes. It is important to understand the effect of these interventions within the context of the intervention as well as across related context. The current study examined the generalization of math fact fluency gains resulting from a computer-based intervention to paper-and-pencil performance. A total of 31 second grade students completed fluency drills on the computer or with paper and pencil. Pretest-posttest performance on both computer and paper and pencil for all students was evaluated using a doubly multivariate repeated measure ANOVA. Results indicated that gains achieved on the computer did not generalize to paper-and-pencil performance. 相似文献

This paper addresses the preliminary development, construct validity, and psychometric properties of a brief self-report measure of psychological distress. 40 items were originally generated by doctoral level psychologists for use in the preliminary clinical sample. Inpatients from a psychiatric unit (N = 125) completed the items, and a principal-components analysis with a direct oblimin rotation was used to evaluate construct validity. The study indicated a four-factor solution, using the constructs of Depression, Hopelessness, Anxiety, and Anger, with good estimates of reliability. After evaluation of factor structure, item analyses, and reliability estimates, a redacted 19-item scale was identified. 相似文献

Terror management theory posits that cultural worldviews buffer people from thoughts and concerns about death. In support of this claim, numerous studies have shown that mortality salience (MS) increases an individual's motivation to uphold and defend important cultural worldviews. We hypothesized that the motivation to defend cultural worldviews following MS would also enhance people's ability to comprehend worldview affirming (vs. disconfirming) information. Three studies investigated this possibility. Study 1 showed that MS (vs. control) increased reading comprehension of a pro‐evolution essay among participants with a strongly evolutionist worldview, but decreased reading comprehension among participants with a strongly creationist worldview. With the use of a pro‐creation essay, Study 2 conceptually replicated these effects and demonstrated that the interactive effect of worldview and death anxiety on reading comprehension was mediated by defensive motivation. Study 3 replicated the results of Studies 1 and 2 among participants with a strongly evolutionist worldview, but only when the information in the essay was perceived as veridical. Discussion focused on the specific process through which MS affects reading comprehension of worldview relevant ideas. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

Classical views of speech perception argue that the static and dynamic characteristics of spectral energy peaks (formants) are the acoustic features that underpin phoneme recognition. Here we use representations where the amplitude modulations of sub-band filtered speech are described, precisely, in terms of co-sinusoidal pulses. These pulses are parameterised in terms of their amplitude, duration and position in time across a large number of spectral channels. Coherent sweeps of energy across this parameter space are identified and the local transitions of pulse features across spectral channels are extracted. Synthesised speech based on manipulations of these local amplitude modulation features was used to explore the basis of intelligibility. The results show that removing changes in amplitude across channels has a much greater impact on intelligibility than differences in sweep transition or duration across channels. This finding has severe implications for future experimental design in the fields of psychophysics, electrophysiology and neuroimaging. 相似文献

The goal of this study was to determine if there was a relationship between athletic identity, a relatively stable individual difference, and athlete satisfaction. A second goal was to evaluate the structure of athletic identity to examine potential differences between facets. Analyzing data from 175 NCAA student athletes, results indicated that use of overall athletic identity hid meaningful relationships between this self-identity concept and level of athlete satisfaction. When examined at the facet level, results indicated that athletic social identity and negative affectivity were positively related to athlete satisfaction while the exclusivity facet of athletic identity was negatively related to athlete satisfaction. 相似文献

Previous research has suggested that when feature inferences have to be made about an instance whose category membership is uncertain, feature-based inductive reasoning is used to the exclusion of category-based induction. These results contrast with the observation that people can and do use category-based induction when category membership is known. The present experiments examined the conditions that drive feature-based and category-based strategies in induction under category uncertainty. Specifically, 2 experiments investigated whether reliance on feature-based inductive strategies is a product of the lack of coherence in the categories used in previous research or is due to the use of a decision-only induction procedure. Experiment 1 found that feature-based reasoning remained the preferred strategy even when categories with relatively high internal coherence were used. Experiment 2 found a shift toward category-based reasoning when participants were trained to classify category members prior to feature induction. Together, these results suggest that an appropriate conceptual representation must be formed through experience with a category before it is likely to be used as a basis for feature induction. 相似文献

Systematic monitoring of individual therapy progress, coupled with feedback to the therapist, reliably enhances therapy outcome by alerting therapists to individual clients who are off track to benefit by the end of therapy. The current paper reviews the possibility of using similar systematic monitoring and feedback of therapy progress as a means to enhance couple therapy outcome, including what measures of therapy progress are most likely to be useful, how to structure feedback to be most useful to therapists, and the likely mediators of the effects of therapy progress feedback. One implicit assumption of therapy progress feedback is that clients unlikely to benefit from therapy can be detected early enough in the course of therapy for corrective action to be taken. As a test of this assumption, midtherapy progress was examined as a predictor of final couple therapy outcome in a sample of 134 distressed couples. Either a brief 7- or 32-item assessment of couple therapy progress at midtherapy detected a substantial proportion (46%) of couples who failed to benefit by the end of therapy. Given that failure to benefit from couple therapy is somewhat predictable across the course of therapy, future research should test whether systematic monitoring and feedback of progress could enhance therapy outcome. 相似文献

This article celebrates the contribution that the American Journal of Psychology (AJP) has made to the area of perceptual-motor skill over its 125-year history. We highlight the articles published in AJP and trace the technical and theoretical developments that stem from this groundbreaking work. Included in our overview are AJP articles on the excitability of the motor system, motor learning, adaptation to visual rearrangement, the ecological approach to perception and action, and the measurement of human handedness. We conclude by identifying a number of areas associated with perceptual-motor skill where AJP continues to make an important contribution. 相似文献
