In this study we examined high frequency heart rate variability (HF‐HRV, a parasympathetic index) both at rest and during challenge, to assess if variations in cardiovascular activity measured during a Stroop task could be used to predict reading achievement in typically developing children. Reading achievement was examined using the Peabody Individual Achievement Test–Revised. Results showed that greater HF‐HRV suppression during both the Stroop word and Stroop word–color conflict tasks was associated with better reading achievement. Higher basal levels of HF‐HRV did not predict better reading scores. These results are among the first to show a link between HF‐HRV and reading achievement in a normative school age population, and offer new insight into the association between cognitive activity and autonomic regulation of the heart. 相似文献

College students experience a myriad of stressors in their daily lives. These stressors are associated with negative outcomes for students, both to their academics and well-being. Healthy, effective coping strategies may support students in navigating personal distress. One of the primary aspects of counselling is to help clients develop and apply such strategies. This study aimed to identify intrapersonal factors that predict types of coping strategies. Participants (N?=?416) identified as undergraduate college students attending a large public university in the southwestern United States. Results indicated that a problem-focused engagement coping strategy was associated with maladaptive factors such as shame and personal distress. Additionally, a problem-focused engagement coping strategy was predicted by potentially more helpful intrapersonal characteristics including guilt (as a motivator) and two dimensions of empathy. Finally, mean comparisons indicated statistically significant differences between identified gender and coping strategies. Implications for college counsellors are discussed.

Twitter is used by athletes, sporting teams and sports media to provide updates on the results of sporting events as they happen. Unlike traditional forms of sports media, online sports media offers the potential for diverse representations of athletes. The current study examined gender in social media coverage of the 2016 Olympic Games using a third wave feminist lens. The analysis focused on the Twitter pages of ‘Team GB’ and the ‘Australian Olympic team’ and the sports stories and images posted during the Rio Olympic Games. Despite a number of traditional differences in the ways that male and females were represented being present, such as the presence of ‘active’ images of male athletes accompanying sports stories and the presence of infantalization in the language used to represent female performers, this analysis demonstrated significant strides forward in terms of the quantity of coverage received by women in online spaces. It further highlights virtual platforms as dynamic spaces for the representation of women athletes. 相似文献

This study took a novel approach to understanding the role of language in spatial development by combining approaches from spatial language and gesture research. It analyzed forty-three 4.5- to 6-year-old’s speech and gesture production during explanations of reasoning behind performance on Spatial Analogies and Children’s Mental Transformation Tasks. Results showed that speech and gesture relevant for solving the trials (disambiguating correct choices) predicted spatial performance when controlling for age, gender, and spatial words and gestures produced. Children performed the spatial tasks well if they produced relevant information either verbally through speech or nonverbally through gesture. These results highlight the importance of not only focusing on concepts children can reference but also on how such concepts are used in spatial tasks. 相似文献

It is difficult for rats to learn to go to an arm of a T-maze to receive food that is dependent on the time of day, unless the amount of food in each daily session is different. In the same task, rats show evidence of time–place discriminations if they are required to press levers in the arms of the T-maze, but learning is only evident when the first lever press is considered, and not the first arm visited. These data suggest that rats struggle to use time as a discriminative stimulus unless the rewards/events differ in some dimension, or unless the goal locations can be visited prior to making a response. If both of these conditions are met in the same task, it might be possible to compare time–place learning in two different measures that essentially indicate performance before and after entering the arms of the T-maze. In the present study, we investigated time–place learning in rats with a levered T-maze task in which the amounts of food varied depending on the time of day. The first arm choices and first lever presses both indicated that the rats had acquired time–place discriminations, and both of these measures became significantly different from chance during the same block. However, there were subtle differences between the two measures, which suggest that time–place discrimination is aided by visiting the goal locations. 相似文献

The domestic dog is an ideal model species in which to study the genetic and environmental factors that influence play behavior. Dogs exist in a wide variety of breeds and frequently engage in multiple forms of play. In the present study, we investigated whether the levels of solitary and social play differed between dogs of three breed types with distinct predatory motor pattern sequences (herding dogs, retrievers, and livestock guarding dogs [LGDs]). Furthermore, we investigated how environmental factors (social and nonsocial contexts) influenced play in dogs of these breed types. Groups of breed-matched dyads with working experience and of equivalent age, sex, and neuter status ratios were exposed to four experimental test conditions and two control conditions in randomized orders. With respect to solitary play, environmental context did have a significant effect, with toys reliably producing the highest levels of solitary play across all breed types. Retrievers engaged in significantly higher levels of solitary play overall than LGDs, and there was a trend in comparison to herding dogs. In contrast, neither environmental context nor breed had a significant effect on social play levels; however, neuter status of the dyads did have a significant effect on social play, with mixed-status dyads engaging in significantly higher levels of social play than same-status dyads. Our findings provide experimental evidence for identifying proximate, environmental stimuli that reliably facilitate social and solitary play and discuss possible genetic (i.e., breed type) and lifetime influences on the form of play in domestic dogs. 相似文献

This article reports on a multi-dimensional model to collection development and licensing applied in our library following a major separation from a joint-licensing venture with another institution. Our model includes the use of several core metrics, including usage and the context in which usage is measured. The model includes three metrics; Research Intensity (RI), Educational Intensity (EI) and Clinical Intensity (CI). These metrics take into account the differences between research and non-research departments, and their disciplinary foci. This model can be used in its entirety or can be customized by selecting the metrics that fits the needs of the library. 相似文献
