Aimed to investigate whether young male and female dancers have different patterns of association between static and dynamic postural balance (PB), 60 dancers from the Australian Ballet School (14–19 years old) were tested for static and dynamic PB with head and lumbar accelerometers. Monotonic relationships between static and dynamic PB were found in head movements among young female dancers in all three directions, but were found for young male dancers in the mediolateral (ML) and anteroposterior (AP) directions only. In lumbar movements, monotonic relationships were found for young female dancers in the AP direction only. Comparing head with lumbar movements in static PB, young male dancers demonstrated monotonic relationships between head and lumbar movements in all 3 directions; however, young female dancers demonstrated monotonic relationships in the AP direction only. In the dynamic measurements, both male and female dancers demonstrated monotonic relationships between head and lumbar movements for all parameters measured in the ML and vertical directions (p < .05). In conclusions, among female dancers static PB ability is correlated with their dynamic ability, whereas among male dancers, no relationship between the static and dynamic PB in the AP direction exists. Male dancers showed head and lumbar coordination in the static PB movement, but both genders manifested no head and lumbar coordination in the AP direction measured for dynamic PB. 相似文献

This critical review aims to more fully situate the claim Martin Heidegger makes in “Letter on Humanism” that a “productive dialogue” between his work and that of Karl Marx is possible. The prompt for this is Paul Laurence Hemming's recently published Heidegger and Marx: A Productive Dialogue over the Language of Humanism which omits to fully account for the historical situation which motivated Heidegger's seemingly positive endorsement of Marxism. This piece will show that there were significant external factors which influenced Heidegger's claim and that, when seen within his broader corpus, these particular comments in “Letter on Humanism” are evidently disingenuous, given that his general opinion of Marxism can only be described as vitriolic. Any attempt to explore how such a “productive dialogue” could be construed must fully contextualise Heidegger's claim for it. This piece will aim to do that, and more broadly explore Heidegger's general opinion of Marxism. 相似文献

The research was designed to determine whether the purported hemispheric asymmetries that are associated with attention deficit/hyperactivity disorder (ADHD) affect performance on a selective attention visual search task, and whether any obtained asymmetry will be modulated by methylphenidate. Two groups of children (8-15 years) with ADHD, one with methylphenidate treatment (ADHD+) and one without (ADHD+), were compared to matched controls on a two-stage visual search task. The task assessed right-left visual field asymmetries and the effects of changing a previous distractor into a target. Such a procedure, related to latent inhibition (LI; poorer performance to a previously irrelevant stimulus than to a novel one), can provide evidence for dysfunctional processing of irrelevant stimuli. All three groups exhibited the LI effect. The ADHD group, however, exhibited less LI for left- than right-side targets, an effect absent in the control and ADHD+ groups, suggesting a lateralized attentional deficit for ADHD+ that was normalized by methylphenidate. 相似文献

Recent research has examined how people predict unobserved features of an object when its category membership is ambiguous.
The debate has focused on whether predictions are based solely on information from the most likely category, or whether information
from other possible categories is also used. In the present experiment, we compared these category-based approaches with feature
conjunction reasoning, where predictions are based on a comparison among exemplars (rather than categories) that share features
with a target object. Reasoning strategies were assessed by examining patterns of feature prediction and by using an eye gaze
measure of attention during induction. The main findings were (1) the majority of participants used feature conjunction rather
than categorical strategies, (2) people predominantly gazed at the exemplars that were most similar to the target object,
and (3) although people gazed most at the most probable category to which an object could belong, they also attended to other
plausible category alternatives during induction. These findings question the extent to which category-based reasoning is
used for induction when category membership is uncertain. 相似文献

Probabilistic models have recently received much attention as accounts of human cognition. However, most research in which
probabilistic models have been used has been focused on formulating the abstract problems behind cognitive tasks and their
optimal solutions, rather than on mechanisms that could implement these solutions. Exemplar models are a successful class
of psychological process models in which an inventory of stored examples is used to solve problems such as identification,
categorization, and function learning. We show that exemplar models can be used to perform a sophisticated form of Monte Carlo
approximation known as importance sampling and thus provide a way to perform approximate Bayesian inference. Simulations of Bayesian inference in speech perception,
generalization along a single dimension, making predictions about everyday events, concept learning, and reconstruction from
memory show that exemplar models can often account for human performance with only a few exemplars, for both simple and relatively
complex prior distributions. These results suggest that exemplar models provide a possible mechanism for implementing at least
some forms of Bayesian inference. 相似文献

The cause of the majority of road crashes can be attributed to drivers’ behavior. Recent in-vehicle monitoring technologies enable continuous and high resolution measurements of drivers’ behaviors. We analyzed the information received from a novel in-vehicle technology which identifies the occurrences of undesirable driving events such as extreme braking and accelerating, sharp cornering and sudden lane changing. We undertook an exploratory analysis to provide better understanding of events frequency (EF) statistical properties. Our findings show higher EF in trip edges (trip beginning and trip end) than in the middle of the trip, higher EF for males than for females and higher EF at nighttime than at daytime. Use of the in-vehicle technology’s continuous and high resolution measurements enabled interesting advanced statistical analyses. Future research can use our findings to build similar statistical models to predict the occurrence of undesirable driving events by other independent variables. 相似文献

Massively multiplayer online role-playing games (MMORPGs) are one of the most interesting innovations in the area of online computer gaming. Given the relative lack of research in the area, the main aims of the study were to examine (a) the impact of online gaming (e.g., typical playing behavior) in the lives of online gamers, (b) the effect of online socializing in the lives of gamers, and (c) why people engage in gender swapping. A self-selecting sample of 119 online gamers ranging from 18 to 69 years of age (M = 28.5 years) completed a questionnaire. The results showed that just over one in five gamers (21%) said they preferred socializing online to offline. Significantly more male gamers than female gamers said that they found it easier to converse online than offline. It was also found that 57% of gamers had engaged in gender swapping, and it is suggested that the online female persona has a number of positive social attributes in a male-oriented environment. 相似文献

The current study used archival data to evaluate the fit of six latent variable models, originally generated by Donders (1999), for the California Verbal Learning Test-Children's Version (CVLT-C; Delis, Kramer, Kaplan, & Ober, 1994) in a large (N = 289) sample of pediatric epilepsy cases presenting at three tertiary treatment centers. Using confirmatory factor analysis, we found that a model including factors of Attention Span, Learning Efficiency, Free Delayed Recall, Cued Delayed Recall, and Inaccurate Recall demonstrated the best relative fit for our data. These findings are consistent with those reported by Donders (1999) in his reanalysis of the CVLT-C standardization sample data, supporting the validity of this factorial model in pediatric epilepsy populations. 相似文献
