To confirm the relationship between pro‐social behaviour and increased physical functioning revealed by previous researchers in Western samples, we conducted four experiments with 378 Chinese undergraduates. The participants' strength to hold, to grip and to lift, as well as their vitality (walking speed), were measured after thinking of acts of kindness. The results showed that recalling pro‐social behaviour (helping others or spending money on others) that had occurred in the past or imagining pro‐social behaviour happening in the future imbued people with more physical strength and vitality. In three experiments, pro‐social behaviour boosted the positive mood of the actors, but the effect was only significant in one experiment, suggesting that the hidden gift may include increased happiness, but that enhanced physical functioning cannot be accounted for by differences in emotions. These results add to the evidence that the function of pro‐social behaviour in promoting physical functioning may be culturally universal. 相似文献

Previous research shows that anger and aggression among road users lead to maladjusted driving and a higher risk of accidents. Especially cyclists as vulnerable road users have a high risk of being injured if they are involved in accidents. This paper examines reasons for cycling anger in two studies. The first study aimed at identifying anger provoking events. Seventy-three cyclists were invited to discuss anger provoking events in a focus group setting. These events were rated regarding their anger intensity, clustered within focus groups, and aggregated across all groups. The first study revealed 208 unique cycling anger provoking events of varying anger intensity that were summarized in six clusters. The second study aimed at validating these anger provoking events, the ratings, and the clusters. Here, 129 participants were asked to complete a four-time point diary study (over the course of ten days), in which they registered all anger provoking events that they experienced while cycling. The results of this study validated most of the anger provoking events of the first study. Both studies show that most anger provoking events are related to conflicts between cyclists with other road users like car drivers and pedestrians. Moreover, conflicts with car drivers seem to cause stronger anger among cyclists than conflicts with other cyclists or pedestrians. Implications for further research and the planning of road infrastructure are discussed. 相似文献

Drivers engage in a host of driving-unrelated tasks while on the road. They listen to music, sing-along, and accompany songs by pounding-out drum-kicks and syncopated rhythms on the steering wheel. However, there is controversy over in-cabin music: Does background music facilitate driver performance via increased arousal leading to more focused concentration, or cause distraction placing drivers at greater risk. In an effort to shed light on the debate, the current study evaluated music engagement by employing Music Performance Analyses with audio recordings from three simulated driving conditions. The results indicate that as the perceptual demands of the primary driving task increased, the secondary music activity was hampered, and subsequently sub-optimal vocal and percussive performances were demonstrated consisting of intonation errors, rhythmic inaccuracy, lack of synchrony, inconsistent and unstable temporal flow, neglect of text, and lyric replacement. The findings seem to point out that drivers allocate greater reserves to music than previously considered, and as drivers do not withdraw altogether from music engagement under high-demand driving conditions, driving may be under-resourced. Exploring active music engagement while driving might assist traffic safety researchers in decoding the effects of In-Car Music on driver behavior. 相似文献

We analyse Hutto & Myin's three arguments against computationalism [Hutto, D., E. Myin, A. Peeters, and F. Zahnoun. Forthcoming. “The Cognitive Basis of Computation: Putting Computation In Its Place.” In The Routledge Handbook of the Computational Mind, edited by M. Sprevak, and M. Colombo. London: Routledge.; Hutto, D., and E. Myin. 2012. Radicalizing Enactivism: Basic Minds Without Content. Cambridge, MA: MIT Press; Hutto, D., and E. Myin. 2017. Evolving Enactivism: Basic Minds Meet Content. Cambridge, MA: MIT Press]. The Hard Problem of Content targets computationalism that relies on semantic notion of computation, claiming that it cannot account for the natural origins of content. The Intentionality Problem is targeted against computationalism using non-semantic accounts of computation, arguing that it fails in explaining intentionality. The Abstraction Problem claims that causal interaction between concrete physical processes and abstract computational properties is problematic. We argue that these arguments are flawed and are not enough to rule out computationalism. 相似文献

Enactivist (Embodied, Embedded, etc.) approaches in cognitive science and philosophy of mind are sometimes, though not always, conjoined with an anti-representational commitment. A weaker anti-representational claim is that ascribing representational content to internal/sub-personal processes is not compulsory when giving psychological explanations. A stronger anti-representational claim is that the very idea of ascribing representational content to internal, sub-personal processes is a theoretical confusion. This paper criticises some of the arguments made by Hutto and Myin (2013, 2017) for the stronger anti-representational claim and suggests that the default Enactivist view should be the weaker non-representational position. 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

To anticipate a product commercial success, companies aim to ensure that product's characteristics are involving users and triggering a positive first user experience as well as all along product's life span. Among these characteristics, triggering users’ emotions is particularly relevant. This article aims to present the different approaches integrating the emotion generated by products. In order to illustrate the emotional potential of certain products a selection of 14 photographs of products was evaluated by 87 participants. Results reveal a significant correlation between cognitive, motivational and subjective components of emotions. A reflexion about the integration of cognitive appraisal assessment and motivational action readiness evaluation into a wilder emotional model is provided. Thus, emotions triggered by a product appear to be a stake for designers and an important variable to introduce in acceptability or user experience models. 相似文献

This study explored infant feeding practice meanings of HIV-positive mothers. Informants were eight black South African mothers (age range 18–29 years) enrolled in a mother-to-child transmission (MTCT) prevention programme. In-depth interviews on factors that influence exclusive breast-feeding were conducted with the mothers. Thematic analysis of the data yielded meanings around practices of knowledge contestation with health care providers and family, work demands, and personal preferences. Moreover, successful breast-feeding by mothers with HIV status may depend on addressing contradictory messages by health workers on infant feeding and community and family pressure to mix-feed the infant children. 相似文献
