Two experiments examined the role of propositional and automatic (ideomotor) processes in cue-elicited responding for rewarding outcomes (beer and chocolate). In a training phase, participants earned either chocolate or beer points by making one of two button-press responses. Rewards were indicated by the presentation of chocolate and beer pictures. On test, each trial began with a picture of beer or chocolate, or a blank screen, and choice of the beer versus chocolate response was assessed in the presence of these three pictures. Participants tended to choose the beer and chocolate response in the presence of the beer and chocolate pictures, respectively. In Experiment 1, instructions signalling that the pictures did not indicate which response would be rewarded significantly reduced the priming effect. In Experiment 2, instructions indicating that the pictures signified which response would not be rewarded resulted in a reversed priming effect. Finally, in both experiments, the priming effect correlated with self-reported beliefs that the cues signalled which response was more likely to be reinforced. These results suggest that cue-elicited response selection is mediated by a propositional belief regarding the efficacy of the response–outcome relationship, rather than an automatic ideomotor mechanism.  相似文献

This study focuses on the parenting practice of inherent value demonstration (IVD), involving parents' tendency to express their values in behaviours and appear satisfied and vital while doing so. Data from Chinese college students (n = 89) confirmed the hypothesis that offspring's perception of their parents as engaged in IVD predicts offspring's subjective well‐being (SWB) through sense of self‐congruence. Importantly, these relations emerged also when controlling for fundamental autonomy‐supportive (FAS) parenting practices such as taking children's perspective, minimising control and allowing choice. These findings are consistent with the view that parents concerned with their children's sense of autonomy may do well to engage in IVD in addition to more fundamental autonomy‐supportive practices. Future research may examine the role of IVD in promoting authentic values that serve as an internal compass that guides children to act in ways that feel self‐congruent.  相似文献

Head-mounted video cameras (with and without an eye camera to track gaze direction) are being increasingly used to study infants’ and young children's visual environments and provide new and often unexpected insights about the visual world from a child's point of view. The challenge in using head cameras is principally conceptual and concerns the match between what these cameras measure and the research question. Head cameras record the scene in front of faces and thus answer questions about those head-centered scenes. In this “Tools of the Trade” article, we consider the unique contributions provided by head-centered video, the limitations and open questions that remain for head-camera methods, and the practical issues of placing head cameras on infants and analyzing the generated video.  相似文献

Objective: Studying personal narratives can generate understanding of how people experience physical and mental illness. However, few studies have explored narratives of engagement in health positive behaviours, with none focusing on men specifically. Thus, we sought to examine men’s experiences of their efforts to engage in and maintain healthy behaviours, focusing on meditation as an example of such behaviour.

Design: We recruited 30 male meditators, using principles of maximum variation sampling, and conducted two in-depth interviews with each, separated by a year. Main outcome measures: We sought to elicit men’s narratives of their experiences of trying to maintain a meditation practice.

Results: We identified an overall theme of a ‘positive health trajectory,’ in particular, making ‘progress’ through meditation. Under this were six main accounts. Only two articulated a ‘positive’ message about progress: Climbing a hierarchy of practitioners, and progress catalysed in other areas of life. The other four reflected the difficulties around progress: Progress being undermined by illness; disappointment with progress; progress ‘forgotten’ (superseded by other concerns); and progress re-conceptualised due to other priorities.

Conclusion: Men’s narratives reveal the way they experience and construct their engagement with meditation – as an example of health behaviour – in terms of progress.  相似文献

Edge misfit dislocations (MDs) formed as result of reactions between 60° glissile threading dislocations and 60° MDs lying on an intersecting glide plane were found in strained GeSi-on-Si(001) and Ge-on-InGaAs/GaAs films. It was demonstrated that dislocations penetrating from the InGaAs buffer layer to the strained Ge film can provoke formation of not only 60° MDs, but also edge MDs on the interface even at minor mismatch of the lattice parameters of the film and the InGaAs/GaAs virtual substrate.  相似文献

The nature of impurity-dislocation interactions is one of the key questions governing the strength and plasticity of solid-solution materials. To investigate the influence of impurities on the mechanical properties of intermetallic NiAl, the electronic structure and energy of NiAl with a <100>{010} edge dislocation and transition-metal impurities was calculated using the real-space tight-binding linear muffin-tin orbital method. The localized electronic states, appearing in the core of the dislocation, are found to lead to strong impurity-dislocation interactions via two mechanisms: firstly, chemical locking, due to strong hybridization between impurity electronic states and dislocation localized states; secondly, electrostatic locking, due to long-range charge oscillations caused by the electron localization in the dislocation core. The results obtained explain qualitatively why the solid-solution hardening effect in NiAl correlates with the electronic structure of impurities rather than with size misfit, as expected according to traditional views.  相似文献

The authors address the effects of money gain and loss on individually perceived value as predicted by prospect theory in a time gain‐and‐loss context. Three experiments were conducted. Experiment 1 results support the prospect theory concept of value function. According to Experiment 2 results, the amount of money involved exerted different impacts on individual perceptions—specifically, study participants preferred gaining $1 on one occasion to gaining 50 cents over two occasions and preferred losing $1 one time to losing 50 cents twice. Further, the combined results indicate that the study participants held different perceptions of the value of “short time” versus “little money”—that is, they preferred saving an extra 2 minutes on one occasion to saving 1 minute on two occasions and preferred waiting an extra 1 minute two times to waiting an extra 2 minutes one time.

This study aimed to investigate the influences of pubertal timing and stressful life events on Chinese adolescents’ depression and delinquency. Sex differences in these influences were also examined. A large sample with 4,228 participants aged 12–15 years (53% girls) was recruited in Beijing, China. Participants’ pubertal development, stressful life events, depressive symptoms, and delinquency were measured using self‐reported questionnaires. Both early maturing girls and boys displayed more delinquency than their same‐sex on‐time and late maturing peers. Early maturing girls displayed more depressive symptoms than on‐time and late maturing girls, but boys in the three maturation groups showed similar levels of depressive symptoms. The interactive effects between early pubertal timing and stressful life events were significant in predicting depression and delinquency, particularly for girls. Early pubertal maturation is an important risk factor for Chinese adolescents’ depression and delinquency. Stressful life events intensified the detrimental effects of early pubertal maturation on adolescents’ depression and delinquency, particularly for girls.  相似文献

Abundant research conducted in Western contexts has shown that biological risk factors such as low resting heart rate (HR) might be related to childhood aggression. However, it was unclear (1) how resting HR, as well as other markers of cardiac functions such as resting vagal tone, may be related to subtypes of aggression such as reactive and proactive aggression, and (2) whether the HR-aggression relation can be replicated in non-Western contexts. Therefore, this study examined the concurrent and prospective relations between resting HR, vagal tone, and Chinese children’s reactive and proactive aggression. Participants were 183 children (M age?=?7.64 years, 91 girls) recruited from an elementary school in Zhenjiang, PRC. Children’s resting HR and vagal tone were assessed in the second grade (T1). Teachers rated children’s reactive and proactive aggression in the second (T1) and fourth grade (T2). Results showed that lower resting HR at T1 was associated with higher reactive and proactive aggression at T1 and T2, and higher vagal tone was associated with lower HR, which in turn was related to higher reactive and proactive aggression at T1 and T2. Lower vagal tone was directly related to higher reactive but not proactive aggression at T1 and T2, whereas lower HR was related to higher reactive aggression at T2 for children with low or moderate vagal tone but was not for children with high vagal tone. These psychophysiological findings from a non-Western context add additional support for both similarities and differences between reactive and proactive aggression in childhood.  相似文献
