ObjectiveThe main objective of the study was to examine the relation of different biological markers to a variety of pleasant and unpleasant psychobiosocial (PBS) states in response to precompetitive stress in sport.DesignA longitudinal design was adopted to assess biological markers and PBS states before several games.MethodA whole team of high-level professional basketball players (9 men, aged from 23 to 37 years) took part in the study. The biological measures included the salivary concentration of testosterone, cortisol, aamylase, and chromogranin A. The psychological measures involved emotional, cognitive, motivational, bodily, kinesthetic, performance, and communicative components of PBS states assessed according to the dimensions of their intensity, frequency, and direction (i.e., perceived effect on performance). Assessment was conducted within 1 h prior to competition on an approximately weekly basis across the whole championship for a total of 12 games played at the team's home.ResultsA series of canonical correlation analyses showed that an increase in the salivary concentration of biological variables was associated with enhanced intensity and frequency scores of pleasant PBS states, as well as enhanced directional values (i.e., perception of facilitative effects) of a range of both pleasant and unpleasant PBS states.ConclusionFindings suggest that elevation of testosterone, cortisol, α-amylase, and chromogranin A in basketball players prior to competition can have a perceived functional effect with respect to the upcoming performance. 相似文献

The aim of this study was to investigate route-learning ability in 67 children aged 5 to 11years and to relate route-learning performance to the components of Baddeley's model of working memory. Children carried out tasks that included measures of verbal and visuospatial short-term memory and executive control and also measures of verbal and visuospatial long-term memory; the route-learning task was conducted using a maze in a virtual environment. In contrast to previous research, correlations were found between both visuospatial and verbal memory tasks-the Corsi task, short-term pattern span, digit span, and visuospatial long-term memory-and route-learning performance. However, further analyses indicated that these relationships were mediated by executive control demands that were common to the tasks, with long-term memory explaining additional unique variance in route learning. 相似文献

Finger counting can be useful in solving arithmetic problems, noticeably because it reduces the working memory demand of mental calculations. However, proprioceptive information might not be sufficient to keep track of the number of fingers raised during problem solving, and visual input may play an important role in this process. The present study was designed to address this question and shows that 8-year-old children look at their fingers in 60% of the trials during finger counting when solving additive problems. Moreover, our results reveal that the frequency of finger looking is negatively correlated with working memory capacities and is higher for more difficult problems. These findings suggest that finger looking is recruited in managing the cognitive demand of the arithmetic task, probably by providing additional external cues to monitor the number of steps that have to be incremented during finger counting. 相似文献

Since Hooker, Finkelman and Schwartzman (Psychometrika 74(3): 419–442, 2009) it is known that person parameter estimates from multidimensional latent variable models can induce unfair classifications via paradoxical scoring effects. The open question as to whether there is a fair and at the same time multidimensional scoring scheme with adequate statistical properties is addressed in this paper. We develop a theorem on the existence of a fair, multidimensional classification scheme in the context of the classical linear factor analysis model and show how the computation of the scoring scheme can be embedded in the context of linear programming. The procedure is illustrated in the framework of scoring the Wechsler Adult Intelligence Scale (WAIS-IV). 相似文献

The ability to navigate new environments has a significant impact on the daily life and independence of people with learning difficulties. The aims of this study were to investigate the development of route learning in Down syndrome (N = 50), Williams syndrome (N = 19), and typically developing children between 5 and 11 years old (N = 108); to investigate use of landmarks; and to relate cognitive functions to route‐learning ability in these groups. Overall, measures of attention and long‐term memory were strongly associated with route learning, even once non‐verbal ability was controlled for. All of the groups, including 5‐ to 6‐year‐old TD children, demonstrated the ability to make use of all landmark types to aid route learning; those near junctions, those further from junctions, and also distant landmarks (e.g. church spire, radio mast). Individuals with WS performed better than a matched subset of TD children on more difficult routes; we suggest that this is supported by relatively strong visual feature recognition in the disorder. Participants with DS who had relatively high levels of non‐verbal ability performed at a similar level to TD participants. 相似文献

Recent findings (Beilock & Carr, 2005) have demonstrated that only individuals with a high working memory capacity (WMC) “choke
under pressure” on math problems with high working memory demands. This suggests that performance pressure hinders those who
are the most qualified to succeed, because it consumes the WMC they usually rely on to achieve superior performance. This
puts into question the use of performance in high-pressure situations as a means of distinguishing individuals with lesser
or greater WMC potentials. While addressing several limitations of past research, we offer evidence that such choking (1)
occurs only in individuals with high WMC, because of their anxiety-ridden perceptions of high-stakes situations, and (2) is
not confined to tasks involving acquired skills and knowledge, but encompasses fluid reasoning abilities or intelligence (Gf).
These findings have strong implications for assessments of people’s intellectual capacities in academic, clinical, work, and
research settings. 相似文献

Management of the research data is an extremely important responsibility of the Principal Investigator (PI) and other members of the research team. Without accurate data, no worthwhile conclusions can be drawn from the research study. Integrity in data management is critical to the success of the research group and to public trust in the research outcomes. One of the primary responsibilities of the PI is to provide proper training to the junior members of the lab. This effort can be buttressed by institutional data policies that are implemented at the group level. Extensive and frequent guidance in good research practices by the PI and other senior research staff is critical to the proper training of new scientists. 相似文献

One of the most pervasive gender stereotypes in Western culture concerns expectations regarding men's and women's emotionality. Whereas men are expected to be anger prone, women are expected to smile more. At the same time, men are generally perceived as more facially dominant and facially dominant individuals are expected to show more anger. That is, both facial appearance and social role expectations would lead observers to expect men to show more anger. The present research had the goal to disentangle the unique contribution of these two factors. As it is impossible in our society to fully untangle the influence of these factors since they are highly confounded, we created an alien society where these factors could be unconfounded. In this alien world, Deluvia, child rearing is exclusively assumed by a third gender, the caregiver, whereas men and women share the same social roles. The facial appearance of the Deluvians was varied along the dominance continuum. The results showed that facially dominant Deluvians, regardless of gender, were expected to show more anger, disgust, and contempt and less happiness, fear, sadness, and surprise. Also, the nurturing caregivers were expected to show less anger, contempt, and disgust as well as more fear, sadness, and surprise, regardless of facial appearance. No effect of gender per se on perceived emotionality was found. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献
