This applied case study centers on two aspects of Peterson’s research as introduced into a large K-12 school in Australia: (i) creating enabling institutions and (ii) applications of character strengths. The paper describes five character strengths initiatives. Four of the strengths initiatives have been integrated into existing school experiences such as English curriculum, school sport, student leadership, and counseling. The fifth initiative involved a brand new program which introduced a Positive Education Curriculum for years?K-10. We describe these five initiatives and then explain how students at the school may experience these in a more holistic and integrated way. We hope that this article will act as a fitting tribute to the legacy of Christopher Peterson. 相似文献

Recent evidence indicates that older adults (aged 65+) are more disrupted by removing interword spaces than young adults (aged 18–30). However, it is not known whether older readers also show greater sensitivity to the more subtle changes to this spacing that frequently occur during normal reading. In the present study the eye movements of young and older adults were examined when reading texts for which interword spacing was normal, condensed to half its normal size or expanded to 1.5 times its normal size. Although these changes in interword spacing affected eye movement behaviour, this influence did not differ between young and older adults. Furthermore, a word frequency manipulation showed that these changes did not affect word identification for either group. The results indicate that older adults can adapt their eye moment behaviour to accommodate subtle changes in the spatial layout of text equally effectively as young adults. 相似文献

Depression-related differences in memory for emotional material are well established, but recognition memory and lexical decision tasks often fail to produce consistent results. The null results from these tasks could be due to inadequacies in traditional analyses rather than the absence of effects. In particular, analyses of accuracy or mean reaction times rely on only a fraction of the behavioural data and are sensitive to individual differences in response biases. The diffusion model addresses these limitations by incorporating all of the behavioural data and separating out response biases. We applied the diffusion model to data from lexical decision and recognition memory tasks and showed consistent effects, specifically a positive emotional bias in non-dysphoric subjects and even-handedness in dysphoric subjects. This pattern was not apparent with comparisons of reaction times or accuracy, consistent with previous null findings. These results suggest a relationship between dysphoria and the internal representation of emotional information. 相似文献

ABSTRACTThis research investigated whether precues engage proactive control to reduce emotional interference during speech production. A picture-word interference task required participants to name target pictures accompanied by taboo, negative, or neutral distractors. Proactive control was manipulated by presenting precues that signalled the type of distractor that would appear on the next trial. Experiment 1 included one block of trials with precues and one without, whereas Experiment 2 mixed precued and uncued trials. Consistent with previous research, picture naming was slowed in both experiments when distractors were taboo or negative compared to neutral, with the greatest slowing effect when distractors were taboo. Evidence that precues engaged proactive control to reduce interference from taboo (but not negative) distractors was found in Experiment 1. In contrast, mixing precued trials in Experiment 2 resulted in no taboo cueing benefit. These results suggest that item-level proactive control can be engaged under certain conditions to reduce taboo interference during speech production, findings that help to refine a role for cognitive control of distraction during speech production. 相似文献

This report used emotion-modulated startle to refine theoretically critical claims about negative affect during tobacco withdrawal. Forty-eight dependent smokers (assigned to either a 24-hr nicotine withdrawal condition or a continued smoking condition) and 48 nonsmokers participated in this study. Participants viewed a series of neutral and unpleasant photographic images and were instructed to enhance, suppress, or maintain their emotional response during specific trials. Participants' startle response was measured before and after this regulation instruction to index 2 components of emotional response: initial negative emotional response intensity and emotion regulation. Compared with the nonwithdrawn groups (continuing smokers and nonsmokers), withdrawal significantly increased self-reported negative affect. However, startle response indicated that emotional response intensity and emotion regulation success were not affected by withdrawal. These results are important because they constrain interpretation of the predominantly self-report literature on the affective consequences of tobacco withdrawal. 相似文献

The purpose was to examine the effectiveness of a physical activity intervention which combined behavior-change strategies with a variety of physical activities for 30 sedentary adults in a 12-wk. intervention that included behavior-change strategy sessions and supervised physical activity. Before and after the intervention, psychological and physiological variables were measured. Statistically significant changes right after the intervention included (1) an increase in physical activity participation, (2) an increase in muscular endurance, flexibility, and predicted VO2 max, and (3) a decrease in the number of barriers to physical activity. Changes in physical self-perception, a psychological variable often linked to increased physical activity, were not statistically significant, but effect sizes were large. The use of behavior-change strategies in conjunction with a variety of physical activities may be useful in improving physical and psychological well-being in previously sedentary adults. Stability of change requires study. 相似文献

This article provides an overview of ethical considerations related to counseling clients who engage in self‐injurious behaviors. Ethical issues concerning client welfare, counselor competence, countertransference, referral and consultation, informed consent, and duty to protect are discussed in relation to the American Counseling Association's (1995) Code of Ethics and Standards of Practice. Implications and recommendations for counselors who work with clients who self‐injure are provided. 相似文献

Five pigeons were trained in a delayed matching-to-sample task with red and green stimuli. The retention interval between sample-stimulus presentation and the availability of the choice stimuli was varied between 0.01 s and 12 s within each session. The probability of food produced by correct-red and correct-green responses was varied across conditions. Sample-stimulus discriminability and response bias were measured at four different retention intervals. The results of these analyses showed an interaction between the discriminability of the sample stimuli and the control exerted by differential reinforcement. At longer retention intervals, sample discriminability decreased and sensitivity of choice behavior to changes in the red/green reinforcer ratio increased. An analogous relation has been reported in conditional discriminations in which the physical disparity of stimuli has been varied. This correspondence suggests that increasing the delay between presentation of one of two stimuli and an opportunity to respond discriminatively to it may be functionally similar to increasing the physical similarity of the two stimuli. 相似文献

Female rats emit ultrasonic vocalizations during copulation. Female vocalizations are associated with darting and other proceptive behavior. In addition, females frequently call while approaching the male. A series of experiments was undertaken to determine whether female rats emit ultrasonic vocalizations in response to other rats or to their odors. Females were exposed either to bedding soiled by males or females or to devocalized conspecifics separated from the subject by a barrier. Females vocalized more to male cues than to female cues, regardless of whether the odor cues were from soiled bedding or from a devocalized conspecific. In addition, subjects vocalized more when presented with a devocalized female rather than a neutral stimulus. Furthermore, devocalized adult males, separated by a barrier, were more effective than either devocalized castrated or juvenile males in eliciting vocalizations; in turn, castrates and juveniles were more effective than neutral stimuli. Female calling was likely induced by odors from the male. In one experiment, the female subject was positioned in such a way that she could neither see or touch the stimulus male. Presentation of tape-recorded male vocalizations did not affect calling by the female. Vocalizations emitted by females in response to male odors may attract males or may facilitate subsequent copulatory behavior by the male. 相似文献
