This study tested the hypothesis that 12-month-old infants' use of force against peers is associated with known risk factors for violence. We conducted a prospective longitudinal study, which included laboratory observations of firstborn British infants (N = 271) during simulated birthday parties. No gender differences in aggressiveness were observed. The infants' observed aggressiveness was significantly correlated with mothers' mood disorder during pregnancy and with mothers' history of conduct problems. Infants' observed aggressiveness was correlated with parents' ratings of infants' anger and aggression, which were also predicted by mothers' mood disorder and history of conduct problems. Our findings indicate that infants at risk for serious aggression can already be identified when the motor ability to use physical force first enters the human repertoire. 相似文献

The detection and subsequent removal of land mines and unexploded ordnance (UXO) from many developing countries are slow, expensive, and dangerous tasks, but have the potential to improve the well-being of millions of people. Consequently, those involved with humanitarian mine and UXO clearance are actively searching for new and more efficient detection technologies. Remote explosive scent tracing (REST) using trained dogs has the potential to be one such technology. However, details regarding how best to train, test, and deploy dogs in this role have never been made publicly available. This article describes how the key characteristics of applied behavior analysis, as described by Baer, Wolf and Risley (1968, 1987), served as important objectives for the research and development of the behavioral technology component of REST while the author worked in humanitarian demining. 相似文献

Three appetitive Pavlovian conditioning experiments with rats examined the associability of stimuli A and B that had a history of compound conditioning (AB+), relative to stimuli X and Y that had a history of conditioning in isolation (X+, Y+). Following this training, Experiment 1 revealed that conditioned responding was higher to X and Y than to A and B (overshadowing). In a subsequent AY+, AX-, BY- test discrimination, the AY/BY discrimination was solved more readily than the AY/AX discrimination. In Experiment 2, following AB+, X+, Y+ training, A and Y were presented as a compound and signaled the availability of reinforcement upon the performance of an instrumental response. Test trials in which A and Y were presented alone, and in extinction, revealed that A acquired greater control of instrumental responding than Y. Experiment 3 revealed that following AB+, X+, Y+ training, A and B served as more effective discriminative stimuli for instrumental responding than X and Y. Overall, these results imply that the associability of stimuli conditioned in compound is higher than stimuli conditioned in isolation. These results are discussed in terms of attentional theories of associative learning. 相似文献

The mere-exposure literature has shown that familiar objects are preferred to novel objects. However, no work has definitively
shown that mere exposure can direct and facilitate approach movements. In Experiment 1, participants were shown stimuli and
were later re-exposed to them along with novel stimuli. Participants were directed to make an approach or avoidant motion
to each and response times were recorded. As predicted, participants were quicker to approach and slower to avoid familiar
relative to novel stimuli. In Experiment 2, participants were shown mere-exposed and novel symbols and were asked to “push”
or “pull” a joystick in response to each, based on their intuition. Extending Experiment 1’s findings, participants freely
selected an approach response more frequently for familiar compared to novel stimuli. Moreover, in this same experiment, familiar
stimuli were judged as more likeable than were novel stimuli, and participants’ liking for familiar stimuli correlated with
the frequency with which they were approached. Implications of these findings are discussed. 相似文献

The human face is important for social communication and in attractiveness judgements. Previous studies indicate that several facial traits may be related to mental and physical health and there is some evidence that individuals are able to judge past health on the basis of facial appearance. The current study builds on this prior work, examining the relationship between static facial appearance and self-reported stress and health. Specifically, we examined (1) within and between individual stress (Study 1) by photographing the same participants at two times, once in a relatively stress free and once in a stressful time, and (2) between individual health (Studies 2A and 2B) by examining self-reported past number of colds as a measure of immune function. All studies demonstrated that individuals could judge the stress and physical health of others from static facial appearance alone at rates greater than chance. Such accuracy may reflect selection pressures to identify stress free and healthy social partners. 相似文献

The authors present the results of a multiyear collaborative research project that involved a counselor educator, graduate‐level school counseling students, and school personnel in defining a new role for counselors in education reform. This collaborative effort was based on an innovative conceptual framework that informs school counselors about specific schooling processes that can either enhance or hinder student academic, personal/social, and career development. 相似文献

Three hundred and eighty‐six participants were interviewed about their experience of dreams that seem to predict an event in the future, and their belief about whether such dreams can be explained naturally or paranormally. For those without university education, participants who had had a dream that seemed to predict the future (termed experiencers) and believers in paranormal explanations for such dreams (termed believers) made more errors on a probabilistic reasoning task about a lottery. Contrary to the chance baseline shift hypothesis experiencers and believers did not give lower estimates than non‐experiencers and non‐believers for the frequency with which others would answer three simple personal questions affirmatively. However, they were more likely to answer the three simple personal questions affirmatively about themselves than were non‐experiencers and non‐believers, which suggests an affirmative bias. This affirmative bias either affects paranormal experience and belief, or is a confound in the methods used in assessing experience and belief. Copyright © 2005 John Wiley & Sons, Ltd. 相似文献

Due to the Common Core State Standards, close reading is becoming a common practice in today’s elementary and middle school classrooms. Qualitative content analysis of journal publications was used to determine the (a) prevalence of close reading in the existing literature, (b) knowledge about close reading from the research literature, (c) themes about close reading in practitioner-oriented articles and (d) questions about close reading in the elementary and middle grade language arts classroom. Results reveal that the majority of articles on close reading are situated in the practitioner literature, with a notable lack of research on close reading. 相似文献
