The degree to which each sport modality relies on cognitive visual skills is hitherto under-researched. This study sought to further understanding of the relationship between sport modality and visual search ability, visual working memory, and reasoning. Ninety-five participants took part in the present study. In order to assess visual search ability, we employed the Visual Search Task. Visual working memory was assessed through the Corsi Block Tapping – Backwards Task. Reasoning abilities were assessed through the Cognitive Reflection Task. Results indicate that visual search skills appear to benefit to a higher extent from open-skill sports when compared to closed-skill sports. It is important to emphasize, however, that this result was associated with a small effect size. Moreover, the present findings indicate that closed-skill athletes do not differ in terms of visual search abilities, working memory, and reasoning abilities when compared to control individuals.  相似文献

The visual behaviors and movement characteristics of pedestrians are related to their surrounding potential safety hazards, such as approaching vehicles. This study primarily aimed to investigate the visual patterns and walking behaviors of pedestrians interacting with approaching vehicles. Field experiments were conducted at two uncontrolled crosswalks located at the Cuihua and Yanta roads in Xi’an, China. The visual performance of pedestrians was assessed using the eye tracking system from SensoMotoric Instruments (SMI). Moreover, motion trajectories of the pedestrians and approaching vehicles were obtained using an unmanned aerial vehicle. Subsequently, the visual attributes and movement trajectories of pedestrians and motion trajectories of approaching vehicles were statistically analyzed. The results showed that approaching vehicles distracted the fixation of crossing pedestrians significantly, and occupied 29.5% of the total duration of fixation; that is, pedestrians always directed more fixation points to the approaching vehicles compared to other stimuli. As a vehicle approached, pedestrians’ fixation shifted from other areas of interest to the vehicle. Moreover, an increase in the velocity of the vehicle and a closer distance between pedestrian and the vehicle resulted in an increase in the pedestrians’ duration of fixation on the approaching vehicle, and they implemented more saccades. Furthermore, approaching vehicle’s velocity and distance between pedestrian and approaching vehicle are not significantly associated with pedestrian’s movement attributes. These findings provide insights into the crossing behavior of pedestrians during pedestrian-vehicle interactions, which could assist future researchers and policy makers.  相似文献

Previous research has shown that listeners follow speaker gaze to mentioned objects in a shared environment to ground referring expressions, both for human and robot speakers. What is less clear is whether the benefit of speaker gaze is due to the inference of referential intentions (Staudte and Crocker, 2011) or simply the (reflexive) shifts in visual attention. That is, is gaze special in how it affects simultaneous utterance comprehension? In four eye-tracking studies we directly contrast speech-aligned speaker gaze of a virtual agent with a non-gaze visual cue (arrow). Our findings show that both cues similarly direct listeners’ attention and that listeners can benefit in utterance comprehension from both cues. Only when they are similarly precise, however, does this equality extend to incongruent cueing sequences: that is, even when the cue sequence does not match the concurrent sequence of spoken referents can listeners benefit from gaze as well as arrows. The results suggest that listeners are able to learn a counter-predictive mapping of both cues to the sequence of referents. Thus, gaze and arrows can in principle be applied with equal flexibility and efficiency during language comprehension.  相似文献

The capacity of the infant to bear affect relies on the capacity of the caregiver until it has achieved enough strength to perform this task itself. In the case of neglect the necessary strength to contain, metabolize and think about affect so that it may be converted into differentiated feelings cannot develop because of the absence of a caregiver capable of sustaining the infant in its emotional development. Instead a system of defence against affect arises in which the affect itself is perceived as intrusive and abusive. Because of neglect a confusion between abuse and affect is to be observed, with catastrophic consequences for the growing up child. Furthermore neglected children can be seduced by external abuse in the hope of being protected from affect that threatens to feel abusive from within. Paradoxically these children are drawn toward abusive situations in the hope of finding some ongoing shelter from unmanageable affect. A corollary of this is that actual containment comes to feel abusive to them: if they are made to feel affect, they perceive the other, who put them in touch with affect, as abusive: thus affect, abuse and containment are confused. Clinical material will support this thesis.  相似文献

At 3–4 months of age, infants respond to gender information in human faces. Specifically, young infants display a visual preference toward female over male faces. In three experiments, using a visual preference task, we investigated the role of hairline information in this bias. In Experiment 1, we presented male and female composite faces with similar hairstyles to 4-month-olds and observed a preference for female faces. In Experiment 2, the faces were presented, but in this instance, without hairline cues, and the preference was eliminated. In Experiment 3, using the same cropping to eliminate hairline cues, but with feminized female faces and masculinized male faces, infants’ preference toward female faces was still not in evidence. The findings show that hairline information is important in young infants’ preferential orientation toward female faces.  相似文献

In this study, we examined the interaction between central and peripheral proprioceptive afferent pathways by applying ankle tendon vibration during postural leaning in different directions. Twenty young participants stood for 60s over the midline of two adjacent force platforms in (a) neutral stance distributing Body Weight (BW) equally between the platforms, (b) forward leaning transferring 80% of BW to the front platform and (c) backward leaning transferring 80% of BW to the rear platform. Participants controlled the degree of leaning by receiving on-line visual feedback of BW distribution matched to a target line. Vibration (80 Hz, 1.5–1.8 mm) was applied over the Achilles or tibialis anterior tendon during the middle 20s of standing. This induced a postural shift towards the vibration side and an increase in the variability of the BW distribution that was greater in backward compared to forward leaning. EMG responses to tendon vibration were independent of the leaning direction. Antagonistic activity also increased in response to vibration, the amplitude of this increase however was direction dependent. These results favor the hypothesis about the central co-modulation of the vibration evoked proprioceptive inflow based on postural and visual feedback rather than muscle tension constraints.  相似文献

Team effectiveness and group performance are often defined by standards set by domain experts. Professional musicians consistently report that sound output is the most important standard for evaluating the quality of group performance in the domain of music. However, across six studies, visual information dominated rapid judgments of group performance. Participants (1062 experts and novices) were able to select the actual winners of live ensemble competitions and distinguish top-ranked orchestras from non-ranked orchestras based on 6-s silent video recordings yet were unable to do so from sound recordings or recordings with both video and sound. These findings suggest that judgments of group performance in the domain of music are driven at least in part by visual cues about group dynamics and leadership.  相似文献

Children diagnosed with reactive attachment disorder (RAD) have been reported to exhibit a multitude of symptoms and behaviors that are not captured by the Diagnostic and Statistical Manual of Mental Disorders criteria. One behavior in particular that has been the source of much argument and controversy is aggression. Although limited research on this topic does support an association between aggression and RAD behaviors, the exact nature of this link remains unclear. This study aims to fill this gap by reporting data from a study that examined the behavioral processes that occur in adopted children with RAD. Guided by the principles of grounded theory, this study employed a multi-stage semi-structured interview design. The sample consisted of 5 adoptive families, and included both adult and child participants, including the adopted children with RAD. The findings revealed 5 prominent themes: The adopted children are reported to engage in extreme and prolonged tantrums, known as rages; children were often inconsolable during these rages; these rages are perceived as uncontrollable by children with RAD; these rages are directed toward a discriminate caregiver; and the impetus for these rages appears to be associated with difficulties in adapting to environmental demands. An in-depth discussion that draws a theoretical connection between these rages and possible deficits in brain-based processes responsible for emotional regulation is presented.  相似文献

This article reflects on a creative visual-narrative approach to understanding South African students’ lived experiences of languages. Data were collected in two interviews: the first entailing a biographical history and the drawing of a linguistic portrait on a simple body outline and the second a narrative interview utilising the portrait generated in the first as a basis for talking about language and identity. Framing the research process in this creative visual mode shifts the focus of narrative talk, simultaneously grounding it in affective, embodied experience, and enabling a reflexive position from which to analyse the taken-for-granted role of language in the minutiae of everyday life. The theoretical lenses of identity and subjectivity are invigorated through these metaphorical representations, and new creative possibilities are released for analysing the role of language in mediating shifting power dynamics in post-apartheid and postcolonial South African life.  相似文献
