The benefits of less repetitive practice in motor learning have been explained by the increased demand for memory processes during the execution of motor skills. Recently, a new perspective associating increased demand for perception with less repetitive practice has also been proposed. Augmented information gathering and visual scanning characterize this higher perceptual demand. To extend our knowledge about mental effort and perceptual differences in practice organization, the association between oculomotor behavior and type of practice was investigated. We required participants to press four keys with different absolute and relative timing goals during the acquisition phase. An eye-tracker captured visual scanning of the skill’s absolute and relative information displayed on the screen. Participants were tested 24 h after acquisition by a retention and transfer test. A higher level of both pupil dilation and amount of eyeblinks indicated an increased mental effort in less repetitive practice compared to more repetitive practice. Visual scanning of the skill’s relative and absolute information was specific to the type of practice. The findings indicate many differences in oculomotor behavior associated with the practice schedule. 相似文献
According to the Body‐Specificity Hypothesis (BSH), people implicitly associate positive ideas with the side of space on which they are able to act more fluently with their dominant hand. Though this hypothesis has been rigorously tested across a variety of populations and tasks, the studies thus far have only been conducted in linguistic and cultural communities which favor the right over the left. Here, we tested the effect of handedness on implicit space‐valence mappings in Tibetan practitioners of Bön who show a strong religious preference for the left, in comparison to an English group. Results showed that Bön right‐handers tended to implicitly associate positive valence more strongly with their dominant side of space despite strong explicit associations between the left and goodness in their religion. This pattern of results found in Bön participants was indistinguishable from that found in English speakers. The findings of the present study support the BSH, demonstrating that space‐valence mappings in people's minds are shaped by their bodily experience, which appears to be independent of space‐valence mappings enshrined in cultural conventions. 相似文献
Objective: A growing body of evidence suggests that affective judgements are distinct from, and exert greater influence on, physical activity behaviours than instrumental judgements.
Design: As part of a randomised controlled trial, 110 insufficiently active, female, university students were randomised to (a) an affective mental contrasting condition, (b) an instrumental mental contrasting condition, or (c) a ‘standard’ mental contrasting intervention (with no modifications). In the analyses concerning the trial’s primary outcome, the affective mental contrasting condition was found to be more effective for increasing physical activity than the standard or instrumental conditions. The purpose of this study was to qualitatively examine the physical activity outcomes and obstacles elicited from participants as part of the three mental contrasting interventions within this trial.
Results: 32 lower-order physical activity judgement themes, categorised within seven high-order themes, were derived through the use of the mental contrasting intervention. In addition to identifying several affective and instrumental outcomes and obstacles that have previously been recognised, participants in this study also highlighted contextualised responses that describe complicated relationships that exist between affective and instrumental judgements.
Conclusions: This study provides fine-grained insight into cognitive processes derived from a novel intervention involving insufficiently active women. 相似文献
The reliability of models with latent variables is questioned by different authors: what is the ontology of mental properties? How to integrate the complex of mental processes with latent variables? All these debates raise the question of the legitimacy of latent variables as methodological approach comparatively to new approaches such as Network analysis. By clearly posing the ontological nature of mental properties as emergent properties of mental processes, and by clearly posing a theory of pragmatist and realistic knowledge, our work seeks to show that latent variables are efficient approaches for inferring mental properties. 相似文献
We aimed to investigate the validity of different self-acceptance measures to predict mental health. Self-acceptance and negative life events, assessed via self-report and rated from life narratives (N = 149), served as predictors of mental health at baseline (T1) and four years later (T2). Path models showed distinguishable, complementary effects of self-reports and other-ratings. A moderate congruence of self- and other-ratings of self-acceptance was observed. Exploratory analyses revealed an association of self-acceptance with emotional words in life narratives. Controlling for negative life events, a positive link and a moderating effect of self-acceptance on mental health at T1, but no prediction of mental health at T2, were found. The study connects research on personality and narratives from a methodological and health psychological perspective. 相似文献
This article explains a range of conceptual and methodological innovations in the use of new media for the clinical practice and public communication of mental health. Building on two current contexts – the emerging research area of new media and mental health, and major reform of the mental health system in Australia – this article presents a scoping review of the online communication of Christian organisations that offer mental health care in Australia. This article compares the websites of 27 Australian Christian mental health organisations, analysing these organisations’ configurations of mainstream and religious modalities of mental health care, their discursive and visual communication strategies, as well as their use of social media platforms. 相似文献
Cognitive architectures serve as both unified theories of the mind and as computational infrastructures for constructing intelligent agents. In this article, we review the evolution of one such framework, Icarus, over the three decades of its development. We discuss the representational and processing assumptions made by different versions of the architecture, their relation to alternative theories, and some promising directions for future research. 相似文献
From the onset of cognitive revolution, the concept of mental imagery has been given different, many times opposing, theoretical accounts. Mental imagery appears to be a ubiquitous, yet wholly individual, easy to explain experience on the one hand, being hard to deal with scientifically on the other hand. The focus of this research is on an enactive approach to visuospatial mental imagery, inspired by Sima’s perceptual instantiation theory. We designed a hybrid computational model, composed of a forward model, an inverse model, both implemented as neural networks, and a memory/controller module, that grounds simple mental concepts, such as a triangle and a square, in perceptual actions, and is able to reimagine these objects by performing the necessary perceptual actions in a simulated humanoid robot. We tested the model on three tasks – salience-based object recognition, imagination-based object recognition and object imagination – and achieved very good results showing, as a proof of concept, that perceptual actions are a viable candidate for grounding the visuospatial mental concepts as well as the credible substrate of visuospatial mental imagery. 相似文献
The concepts of “good” and “bad” are associated with right and left space. Individuals tend to associate good things with the side of their dominant hand, where they experience greater motor fluency, and bad things with their nondominant side. This mapping has been shown to be flexible: Changing the relative fluency of the hands, or even observing a change in someone else's motor fluency, results in a reversal of the conceptual mapping, such that good things become associated with the side of the nondominant hand. Yet, based on prior studies, it is unclear whether space–valence associations were determined by the experience of fluent versus disfluent actions, or by the mere expectation of fluency. Here, we tested the role of expected fluency by removing motor execution and perceptual feedback altogether. Participants were asked to imagine themselves performing a psychomotor task with one of their hands impaired, after which their implicit space–valence mapping was measured. After imagining that their right hand was impaired, right‐handed participants showed the “good is left” association typical of left‐handers. Motor imagery can change people's implicit associations between space and emotional valence. Although asymmetric motor experience may be necessary to establish body‐specific associations between space and valence initially, neither motoric nor perceptual experience is needed to change these associations subsequently. The mere expectation of fluent versus disfluenct actions can drive fluency‐based effects on people's implicit spatialization of “good” and “bad.” These results suggest a reconsideration of the mechanisms and boundary conditions of fluency effects. 相似文献
