School psychologists have been called upon to take a leadership role in school-violence prevention, but little is known about their involvement in this issue, especially in states where school shootings have occurred. The current study surveyed 258 Michigan school psychologists about their role in prevention of school violence. Analysis suggested respondents felt prepared to address violence prevention but do not have a leadership role and are not sought for advice about prevention. The number of annual special education evaluations was significantly associated with frequency of being sought for advice on violence prevention but was not related to perceptions of leadership or preparedness. Modest relationships were noted between feeling prepared, knowledge of risk factors, and self-perceptions of a leadership role. Suggestions for research are included. 相似文献

The current experiment investigated ontogenetic forgetting on a novel object-recognition task similar to that of Besheer and Bevins. 18-day-old pups (n = 49) and adult (n = 29) rats were tested at two retention intervals (1 min. or 120 min.). By employing exclusion criteria which demanded minimum amounts of object exploration at training and test, the performance of 18-day-old pups but not that of adults was significantly impaired at 120 min. relative to 1 min. Analysis indicated that the ontogeny of the learning and memory measured in novel object recognition follows a developmental trend similar to that of other forms of learning, with older animals remembering more and thus performing better than younger animals. Unfortunately, given the extreme variability inherent to the task and large N necessary to achieve significance, the use of this task in studies of learning, memory, and development is discouraged. 相似文献

Analysis of naturalistic chewing patterns may provide insight into mapping the neural substrates of jaw movement control systems,
including their adaptive modification during the classically conditioned jaw movement (CJM) paradigm. Here, New Zealand White
rabbits were administered food and water stimuli orally to evaluate the influence of stimulus consistency on masticatory pattern.
Chewing patterns were recorded via video camera and movements were analyzed by computerized image analysis. The mandibular
kinematics, specifically the extent of dorsal/ventral, medial/lateral, and rostral/caudal movement, were significantly larger
in food-evoked than water-evoked chewing. Water-evoked chewing frequency, however, was significantly higher than that of food-evoked
movements. In light of known cortical mastication modulatory centers, our findings implicate different neural substrates for
the responses to food and water stimuli in the rabbit. A detailed delineation of jaw movement patterns and circuitry is essential
to characterize the neural substrates of CJM. 相似文献

From clinical material of patient-analyst pairs caught up in negativistic transference-countertransference enmeshment, the defensive functions of negativism are explored for both patient and analyst. Fascination with and dread of the negative intersect as patients struggle to avoid terrifying aspects of self and other. The analyst works to avoid being trapped in negativism within the dyad. Containing, metabolizing, and transforming the dyad's mutual destructiveness and mutual love enable analyst and patient to feel safer with both. How to play with the negative, to engage the patient in play at the intersection of destructive negativism and dangerous love, is described. 相似文献

Cultural competency guidelines and policies are being widely established. Yet some critics have challenged the evidence for cultural competency and the lack of efficacy studies that demonstrate its outcomes. Various positions are examined that discuss cultural competency research. They include the need for more resources for research, scientific practices that overlook ethnic research findings, fruitfulness of theory-driven rather than population-based research, problems in defining cultural competency as a technique, and development of policies in the absence of research. Implications of these positions are discussed. 相似文献

The present study evaluated the effectiveness of the Positive Parenting Program (Triple P) with a sample of Chinese parents of children with early onset conduct-related problems in Hong Kong. The participants consisted of 91 parents whose children attended maternal and child health centers and child assessment centers for service, and were between three to seven years old. Participants were randomly assigned to the intervention (TP) and a waitlist control group (WL). There was no significant difference in pre-intervention measures between the two groups. However, at post intervention, participants in the TP group reported significantly lower levels of child behavior problems, lower dysfunctional parenting styles, and higher parent sense of competence, compared to the WL group. Implications of these findings for the use of Triple P with families of Chinese descent are discussed. 相似文献

Delayed matching to complex, two-picture samples (e.g., cat-dog) may be improved when the samples occasion differential verbal behavior. In Experiment 1, individuals with mental retardation matched picture comparisons to identical single-picture samples or to two-picture samples, one of which was identical to a comparison. Accuracy scores were typically high on single-picture trials under both simultaneous and delayed matching conditions. Scores on two-picture trials were also high during the simultaneous condition but were lower during the delay condition. However, scores improved on delayed two-picture trials when each of the sample pictures was named aloud before comparison responding. Experiment 2 replicated these results with preschoolers with typical development and a youth with mental retardation. Sample naming also improved the preschoolers' matching when the samples were pairs of spoken names and the correct comparison picture matched one of the names. Collectively, the participants could produce the verbal behavior that might have improved performance, but typically did not do so unless the procedure required it. The success of the naming intervention recommends it for improving the observing and remembering of multiple elements of complex instructional stimuli. 相似文献

The interactive effect of leader-member exchange and communication frequency on performance ratings 总被引:2,自引:0,他引:2
The authors tested the hypothesis that communication frequency moderates the relationship between leader-member exchange (LMX) and job-performance ratings. In a study of 188 private sector workers, they found that LMX was more strongly related to job-performance ratings among individuals reporting frequent communication with the supervisor than among those reporting infrequent communication. At high levels of LMX, workers reporting frequent communication with the supervisor received more favorable job-performance ratings than did workers reporting infrequent communication. In contrast, at low levels of LMX, workers reporting frequent communication with the supervisor received less favorable job-performance ratings than workers reporting infrequent communication. The authors conducted a 2nd study of 153 public sector workers to provide a constructive replication and found similar results. 相似文献

The relation between mother–infant coordinated interpersonal timing, an automated microanalytic measure of dyadic vocal coordination, and maternal sensitivity was explored. Thirty-five mothers and their developmentally normal 4-month-old infants were audio-recorded during a 20-min laboratory vocal interaction session, that was later analyzed for degree of vocal coordination. Maternal Sensitivity ratings (Ainsworth & Bell, 1969) were based on a video-taped 45-min unstructured laboratory interaction period. A significant curvilinear relation between the degree to which mother coordinated her noninterruptive co-occurring speech to that of her infant was found and revealed that mothers highest in sensitivity were characterized by moderate levels of coordination. Examining mother-infant interaction at the specific behavioral level, while incorporating tests of nonlinear trends, may provide important information about the nature of sensitive parenting. 相似文献
