Each eye movement introduces changes in the retinal location of objects. How a stable spatiotopic representation emerges from such variable input is an important question for the study of vision. Researchers have classically probed human observers' performance in a task requiring a location judgment about an object presented at different locations across a saccade. Correct performance on this task requires realigning or remapping retinal locations to compensate for the saccade. A recent study showed that performance improved with longer presaccadic viewing time, suggesting that accurate spatiotopic representations take time to build up. The first goal of the study was to replicate that finding. Two experiments, one an exact replication and the second a modified version, failed to replicate improved performance with longer presaccadic viewing time. The second goal of this study was to examine the role of attention in constructing spatiotopic representations, as theoretical and neurophysiological accounts of remapping have proposed that only attended targets are remapped. A third experiment thus manipulated attention with a spatial cueing paradigm and compared transsaccadic location performance of attended versus unattended targets. No difference in spatiotopic performance was found between attended and unattended targets. Although only negative results are reported, they might nevertheless suggest that spatiotopic representations are relatively stable over time. 相似文献

Tool use in left brain damage and Alzheimer's disease: What about function and manipulation knowledge? 下载免费PDF全文
Christophe Jarry François Osiurak Jérémy Besnard Josselin Baumard Mathieu Lesourd Bernard Croisile Frédérique Etcharry‐Bouyx Valérie Chauviré Didier Le Gall 《Journal of Neuropsychology》2016,10(1):154-159
Tool use disorders are usually associated with difficulties in retrieving function and manipulation knowledge. Here, we investigate tool use (Real Tool Use, RTU), function (Functional Association, FA) and manipulation knowledge (Gesture Recognition, GR) in 17 left‐brain‐damaged (LBD) patients and 14 AD patients (Alzheimer disease). LBD group exhibited predicted deficit on RTU but not on FA and GR while AD patients showed deficits on GR and FA with preserved tool use skills. These findings question the role played by function and manipulation knowledge in actual tool use. 相似文献

Not being able to combine work with family properly is negatively related to employees’ quality of life. Some firms are aware of this reality and provide their employees family-friendly practices, a set of practices designed to enable employees a work–family balance. Family-friendly practices are classified in three subsets: family support practices, flexible arrangement practices, and parental leave practices. Then, this paper analyzes the impact of different subsets of family-friendly practices on work–family balance for women and men subsamples, as well as to disentangle the mechanisms through with such effects occur. Based on a representative sample of 8,061 Spanish workers and using the Baron and Kenny procedure to test for mediation, the results show that the three subsets of family-friendly practices increase work–family balance for both genders, although some of them have different effects for women and men. In line with societal gender role expectation, family support practices better accommodate men’s need, increasing work–family balance almost for them, and parental leave practices women’s need, increasing work–family balance more for them. However, flexible arrangement practices increase work–family balance equally for both genders. Moreover, in all cases, the effect of family-friendly practices on work–family balance goes beyond the effect of time outside work and time at work, then this partial mediation indicates that time is an important mechanism in achieving work–family balance. In sum, offering employees family-friendly practices is a good starting point in order to increase people’s quality of life by helping them achieve work–family balance. 相似文献

Persons with Down syndrome (DS) suffer from prefrontal cortex dysfunction and deficits in executive functions. The current study examined the effects assisted cycling therapy (ACT) on short-term (STM) and working memory (WM) in adolescents with DS. During ACT, the cadence of participants on a stationary bicycle was augmented with an electrical motor to 180% of the voluntary cadence. Participants completed eight weeks of ACT (n?=?17), eight weeks of voluntary cycling (VC) at their own preferred cadence (n?=?16), or eight weeks of no cycling (np?≥?.149) and working memory improved only in the ACT group (Hedge’s g?=?1.66; p?=?.003). The results indicate that assisted high-cadence cycling (i.e. ACT) produces superior neural benefits in the dorsolateral prefrontal cortex compared to VC. 相似文献

Outside the cognitive psychologist's laboratory, problem-solving is an activity that takes place in a rich web of interactions involving people and artefacts. This interactivity is constituted by fine-grained action–perception cycles, and it allows a reasoner's comprehension of the problem to emerge from a coalition of internal and external resources. Taking an ecological approach to problem-solving, this paper introduces a qualitative method, Cognitive Event Analysis, for studying the fine-grained interactivity between a problem-solving agent and his/her environment. To demonstrate the potential of this method, it is used to study a single subject solving the so-called 17 Animals problem using a material model. The fine-grained procedure allows tracking the solution to a serendipity that was brought about because of the participant's aesthetic considerations and a change in her perceptual figure-ground configuration. While a qualitative single-case method cannot prove specific models of problem-solving, it questions prevalent mentalist models, and it generates new hypotheses on insight problem-solving, because it allows the researcher to attend to outliers and to variability on a fast and fine-grained between-measurement timescale. 相似文献

Health and welfare have emerged as key vehicles used to legitimize and position the identities that older people adopt in contemporary western societies. Both health and welfare contain specific yet continually changing technologies that function to mediate relations between older people and the state. Medico-technical and care management discourses have been presented as adding choice and reducing limitations associated with adult aging. However, they also represent an increase in professional control that can be exerted on lifestyles in older age and thus, the wider social meanings associated with that part of the lifecourse. This article presents a theoretical analysis based on a critical reading of the work of Michel Foucault; identifies the interrelationship between managers and older people in terms of power, surveillance and normalization; and highlights how and why older people remain the subjects of legitimizing professional gazes. 相似文献

This paper argues that sharp distinctions between formal ritual action and everyday practice cannot always be sustained. Drawing on ethnographic fieldwork among British Quakers and Swedish charismatic Protestants, we seek to show that both groups manifest an experiential aesthetic that constructs and is constructed by engagement in daily life. The Quaker aesthetic we call 'the plain', and the charismatic aesthetic we term 'the positive'. In presenting our argument, we adopt Bourdieu's concept of habitus and extend its meaning to take account of material culture in the establishment of religious commitment. 相似文献

Remarks On Quantum Ontology 总被引:2,自引:0,他引:2
Despite the discrepancies between quantum objects and `classical' ones, mainly with regard to the fact that the latter may be thought of as `individuals', contrary to the former, we still regard the quanta as `things' in our ordinary discourse as well as in the logico-mathematical basis of quantum theories. This paper considers some possibilities for accomodating the logico-mathematical framework of the theories which deal with such a strange ontology where the inhabitants are things devoid of identity and both having and not having certain properties.``All right', said the Cat; and this time it vanished quite slowly, beginning with the end of the tail, and ending with the grin, which remained some time after the rest of it had gone.``Well! I've often seen a cat without a grin', thought Alice, ``but a grin without a cat! It's the most curious thing I ever saw in all my life!'Lewis Carroll 相似文献

The current study examined the relationship between childhood anxiety and threat perception abnormalities. Children (N = 105) were exposed to stories reflecting three types of anxiety: social anxiety, separation anxiety, and generalized anxiety. From children's reactions to the stories, a number of threat perception indices were derived. Children's level of anxiety was assessed by means of questionnaires and a structured diagnostic interview. Results indicated that high levels of anxiety, as measured by questionnaires and interview, were accompanied by a high frequency of threat perception, high ratings of threat, a high frequency of threatening interpretations, high levels of negative feelings and cognitions, and an early detection of threat. Furthermore, results seemed to suggest that threat perception abnormalities were mediated by children's general level of anxiety rather than by levels of specific anxiety symptoms. 相似文献
