Summary feedback involves withholding feedback from subjects until the last trial in a block is completed, and then presenting feedback about each trial. A variation of this method, called average feedback (Young & Schmidt, 1992), presents subjects with only the mean of the trial block. We investigated whether these methods have similar effects on acquisition and retention of a simple motor skill. Five groups of subjects (n = 16 per group) performed 60 acquisition trials of an aiming task involving both spatial and temporal accuracy. We presented average and summary feedback based on either 5-trial blocks or 15-trial blocks and compared these schedules with every-trial feedback. During acquisition, all groups improved with practice, with a slight tendency for the every-trial condition to have less absolute error than the longer summary and average conditions. Analysis of delayed no-feedback retention tests, however, revealed a strong advantage for the 5-trial summary and average conditions compared with the every-trial condition. In addition, we found that for long blocks of acquisition trials without augmented feedback, the performance variability of those trials was associated with retention performance. Results are discussed in terms of how these different manipulations may make feedback less useful during acquisition, but foster the use of certain information processing activities that enhance overall learning. 相似文献

Humphrey and Dahlstrom (1995) presented a study on the comparability of MMPI/MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) profiles in which they concluded that "the bases for clinical interpretation derived from the MMPI and MMPI-2 profiles were sufficiently at variance to require different conclusions" [sic] (p. 2). In this brief critique, we identify procedural and data-analytical deficiencies that invalidate Humphrey and Dahlstrom's argument. Their blanket recommendation based on this argument, namely, that clinicians routinely plot both MMPI and MMPI-2 profiles, is unwarranted. 相似文献

To identify reasons for discrepancies between parent and child reports of child/adolescents's psychiatric symptoms, parents and adolescents (51 pairs) were asked to guess what the other would answer to questions from the PC-DISC about the adolescent's psychiatric symptoms, and to explain why they expected disagreement when the answer they provided for the other was different from their own. Adolescents' explanations for expecting (1) parental denial of symptoms the adolescent reported were: the parent was unaware of, forgot about, assumed the adolescent could not have, or trivialized the symptom; and (2) parental report of symptoms the adolescent denied were: the parent misread or exaggerated the adolescent's symptom, had too high expectations for the adolescent's behavior, put a negative label on or did not trust the adolescent. Parents' reasons for expecting their children to (1) deny symptoms the parents reported were: the adolescent did not remember how s/he felt, lied, did not recognize or minimized the importance or frequency of the symptom; and (2) report symptoms the parents denied were: the adolescent lied, exaggerated the importance of or interpreted the symptom differently.Support for this work was provided by National Institute of Drug Abuse grant number DA-05585 (Dr. Cottler, P.I.), and National Institute of Mental Health grants numbers MH-31302 (Dr. R.

We examined the nature of referrals to a health center-based pediatric psychology service from 1990 to 1993 and assessed the satisfaction of health professionals with these services. Archival evaluation of 1467 records showed that over half of the consultation requests came from general pediatrics, pediatric neurology, and surgical services and that 70% of the psychological services were delivered on an outpatient basis. The most frequent referrals were for cognitive/neuropsychological evaluation and externalizing behavior problems. Pediatric psychology trainees were involved in 94% of the consultations. Survey of health professionals (n = 143) indicated very high overall satisfaction with the quality of services delivered. Presenting problems yielding the greatest likelihood for future consultation requests were behavior problems, child abuse, coping with illness, and depression/suicide. Results are discussed in the context of previous evaluations of pediatric psychology services and recommendations for future evaluation research. 相似文献

We reviewed the literature on the detection and management of mental health disorders within the context of pediatric primary care. Pediatricians have displayed a low sensitivity and high specificity in research investigating the detection of mental health impairment in children. Active management efforts characterize approaches to identified cases with more recently trained primary care pediatricians displaying a wider range of skills in managing mental health disorders. Few efforts have been made by pediatric psychologists to develop strategies for enhancing detection rates and management or to empirically evaluate the integration of pediatric psychology services into the primary care context. A conceptual model of factors influencing detection rates and ongoing management of mental health disorders within pediatric primary care is presented. Recommendations are made for more direct involvement of pediatric psychologists within the primary care context. 相似文献

The spiritual journey of a Buddhist devotee is a continual exploration of the truth of interdependence which Siddhartha Gautama
realized to become the Buddha, “the Enlightened One.” On the morning of the enlightenment, the Buddha apprehended the truth
that all things and all beings are interconnected and mutually dependent in time and space. One measure of the spiritual maturity
of the Buddhist devotee is his or her appreciation for the profound responsibilities and gratitude we share for all things.
To illustrate the significance of interdependence in our lives, the author turns to the wisdom contained inVital Involvement in Old Age by Erik and Joan Erikson and Helen Q. Kivnick. 相似文献

Abstract— Infants' auditory detection thresholds are higher than adult thresh olds. Since adults listen selectively for an expected test tone frequency, and selective listening improves their detection performance, one hypothesis about why infant thresholds are high is that infants do not listen selectively. This hypothesis was tested by obtaining listening bands from adults and from 7- to 9-month-old infants. The results replicate earlier findings that adults listen selectively but indicate that infants do not. Lack of selective listening likely contributes to infants' high thresholds. Further, the finding that infants and adults have different listening strategies has implications for infants' auditory perception in general. 相似文献

Several factors are critical in designing effective simulator systems for driving research and driver assessment. First, there is cost, in terms of which, less is better. Costly systems are sometimes fine for specific research purposes, but they are impractical for most other purposes. Second, there is realism; in this case, more may be better, but we don’t know how much realism is really necessary for good prediction of actual driving behaviors. Recent evidence suggests that real-world clutter may enhance prediction, but it also makes interpreting research more difficult. More realism may increase cost, but this is not necessarily the case. Third, there is user-friendliness, in terms of which, again, more is better. Systems that are easier to operate require less-highly trained personnel; hence, increasing user-friendliness also decreases cost, especially for assessment. We demonstrated a highly user-friendly, low-cost, moderately realistic, and partly interactive computer-video driving research and assessment system. In recent research, we obtained multipleR values ofA7 for older drivers with only three to four scenarios predicting a real-world crash index. 相似文献
