Retrieval practice and spacing out studying help increase learning. Introductory Psychology students at nine colleges/universities took quizzes with more (RP+) or less (RP?) retrieval practice and more (SP+) or less (SP?) spacing between quizzes. We compared (N = 351) scores on class exams and on a standardized test. We also measured key student variables (e.g., depth of processing). GPA predicted a significant portion of variance in exam scores, R2 = 0.05, F(1, 204) = 10.84, p = 0.001. We found a main effect for retrieval practice and a significant retrieval by spacing practice interaction, R2 = 0.28, F(3, 201) = 27.38, p < 0.001. Students using SP+, as well as those with SP? and RP?, scored higher than students using SP? and RP+. In practice, closer attention needs to be paid to quiz and exam content overlap and the duration within which repetition is used. 相似文献

Limited research exists concerning male partners' participation in prenatal genetic counseling (R. Kenen, A. C. M. Smith, C. Watkins, & C. Zuber-Pitore, J. Genet Corns 9, 33–45, 2000). To further understand paternal participation, we interviewed 17 experienced prenatal genetic counselors to assess their perspectives on this issue. We investigated 6 research questions: 1) How do genetic counselors define paternal involvement, 2) how do they determine and address problematic involvement, 3) what factors influence involvement, 4) was paternal involvement addressed in training, 5) how might training be improved, and 6) how do participant strategies for addressing involvement compare to those of marriage/family therapists? Qualitative analysis revealed that 1) participants regard paternal involvement asimportant; 2) most address problematic involvement with strategies similar to those of marital/family therapists; 3) influential factors include male partner's characteristics, the couple's relationship (including culturalpractices), and pregnancy factors; and 4) participants received little or notraining on paternal involvement and recommended didactic and experientialactivities. Implications and research recommendations are presented. 相似文献

This repeated measures study examines (1) the change in subjective risk of mutations pre- to postcounseling, (2) the accuracy of BRCAPRO estimates of mutations, and (3) the discrepancy between subjective risk and BRCAPRO estimates of mutations before and after genetic counseling. Ninety-nine Ashkenazi Jewish individuals pursued testing for BRCA1/2 mutations. Most had a personal cancer history (N = 51; family only: N = 48); and received uninformative negative results (N = 66; positives: N = 23; informative negative: N = 10). The coping strategy of defensive pessimism predicts that individuals will believe the worst case scenario to better cope with a potential negative outcome. Consistent with this, most felt they would have a mutation, if not mutations in both genes. The BRCAPRO model appeared to overestimate risk of having a mutation in this sample (p < .001). BRCAPRO overestimates notwithstanding, genetic counseling increased accuracy of subjective risk (p < .01). Individuals with a family-only cancer history had the least accurate estimates of risk (p < .05) and may need further intervention to either manage anxiety or improve knowledge. 相似文献

The purpose of this study was to evaluate auditory feedback to increase the effectiveness of throwing a “right cross.” Auditory feedback, implemented by the mixed martial arts coach, was evaluated in multiple baselines across participants design with four mixed martial arts students, two males and two females, 25–54 years old. The target behavior was the percentage of correct steps in the 20‐step task analysis of throwing a right cross. In the auditory feedback procedure, the coach used a handheld clicker and make the clicking sound as a reinforcer each time the participant performed a specific step in the task analysis correctly. This process continued until all steps were performed correctly. The percentage of correct steps of the right cross improved substantially during assessment sessions following the introduction of the auditory feedback and maintained at 90% or more for all participants during follow‐up. Improvements were also noted in the social validity assessment. 相似文献

Statistical learning (SL), sensitivity to probabilistic regularities in sensory input, has been widely implicated in cognitive and perceptual development. Little is known, however, about the underlying mechanisms of SL and whether they undergo developmental change. One way to approach these questions is to compare SL across perceptual modalities. While a decade of research has compared auditory and visual SL in adults, we present the first direct comparison of visual and auditory SL in infants (8–10 months). Learning was evidenced in both perceptual modalities but with opposite directions of preference: Infants in the auditory condition displayed a novelty preference, while infants in the visual condition showed a familiarity preference. Interpreting these results within the Hunter and Ames model (1988), where familiarity preferences reflect a weaker stage of encoding than novelty preferences, we conclude that there is weaker learning in the visual modality than the auditory modality for this age. In addition, we found evidence of different developmental trajectories across modalities: Auditory SL increased while visual SL did not change for this age range. The results suggest that SL is not an abstract, amodal ability; for the types of stimuli and statistics tested, we find that auditory SL precedes the development of visual SL and is consistent with recent work comparing SL across modalities in older children. 相似文献

Infants' intermodal perception of two levels of temporal structure uniting the visual and acoustic stimulation from natural, complex events was investigated in four experiments. Films depicting a single object (single, large marble) and a compound object (group of smaller marbles) colliding against a surface in an erratic pattern were presented to infants between 3 and
months of age using an intermodal preference and search method. These stimulus events portrayed two levels of invariant temporal structure: (a) temporal synchrony united the sights and sounds of object impact, and (b) temporal microstructure, the internal temporal structure of each impact sound and motion, specified the composition of the object (single vs. compound). Experiment 1 demonstrated that by 6 months infants detected a relation between the audible and visible stimulation from these events when both levels of invariant temporal structure guided their intermodal exploration. Experiment 2 revealed that by 6 months infants detected the bimodal temporal microstructure specifying object composition. They looked predominantly to the film whose natural soundtrack was played even though the motions of objects in both films were synchronized with the soundtrack. Experiment 3 assessed infants' sensitivity to temporal synchrony relations. Two films depicting objects of the same composition were presented while the motions of only one of them was synchronized with the appropriate soundtrack. Both
6-month-olds showed evidence of detecting temporal synchrony relations under some conditions. Experiment 4 examined how temporal synchrony and temporal microstructure interact in directing intermodal exploration. The natural soundtrack to one of the objects was played out-of-synchrony with the motions of both. In contrast with the results of Experiment 2, infants at 6 months showed no evidence of detecting a relationship between the film and its appropriate soundtrack. This suggests that the temporal asynchrony disrupted their detection of the temporal microstructure specifying object composition. Results of these studies support on invariant-detection view of the development of intermodal perception. 相似文献

In this study, the history of psychological testing in Japan is described using the oral history method. Seven test developers discussed the development of Japanese versions of the Wechsler Intelligence Scale, Binet-Simon Intelligence Scale, and Kaufman Assessment Battery for Children. Three conclusions were identified. First, the motivation for developing the tests shifted from one of personal aspiration to a wider responsibility of specialists' desiring to make social contributions. Second, the test developers shifted from working in small, familiar, collaborative groups to working in groups of specialists conducting well-organized projects. Third, the development of tests has variously been led by researchers, publishers, researcher-and-publisher collaborations, or institutes. In addition, this study identifies contemporary challenges for developing psychological tests, specifically due to insufficient numbers of participants and test developers. 相似文献

Disengaged test taking tends to be most prevalent with low-stakes tests. This has led to questions about the validity of aggregated scores from large-scale international assessments such as PISA and TIMSS, as previous research has found a meaningful correlation between the mean engagement and mean performance of countries. The current study, using data from the computer-based version of the PISA-Based Test for Schools, examined the distortive effects of differential engagement on aggregated school-level scores. The results showed that, although there was considerable differential engagement among schools, the school means were highly stable due to two factors. First, any distortive effects of disengagement in a school were diluted by a high proportion of the students exhibiting no non-effortful behavior. Second, and most interestingly, disengagement produced both positive and negative distortion of individual student scores, which tended to cancel out much of the net distortive effect on the school’s mean. 相似文献

Although little studied, whining is a vocal pattern that is both familiar and irritating to parents of preschool‐ and early school‐age children. The current study employed multidimensional scaling to identify the crucial acoustic characteristics of whining speech by analysing participants' perceptions of its similarity to other types of speech (question, neutral speech, angry statement, demand, and boasting). We discovered not only that participants find whining speech more annoying than other forms of speech, but that it shares the salient acoustic characteristics found in motherese, namely increased pitch, slowed production, and exaggerated pitch contours. We think that this relationship is not random but may reflect the fact that the two forms of vocalization are the result of a similar accommodation to a universal human auditory sensitivity to the prosody of both forms of speech.
