Two experiments were conducted to examine decision process in intertemporal choice with spatial and temporal action dynamic measures generated from cursor movement. The effects of the context valence (gain and loss) and magnitude of the payoffs (small and large) were investigated. Other factors examined were differences between decisions made at versus away from the indifference point and response variability dependent on what was selected (delayed versus non‐delayed/less‐delayed payoff). Using principal components analysis, decision process is described with three orthogonal components. General decision difficulty is encompassed by two components: (1) Conflict, depicted by Idle time and deviations from a direct choice path, and (2) decision uncertainty or Wavering, described by left‐right directional flips. A general Locomotion factor was also present. In Experiment 1, Conflict was best at capturing the gain/loss and magnitude context effects. Greater Conflict was observed in the loss context and the small magnitude condition. When choices were closer to the indifference point, Wavering was most salient. In Experiment 2, when selecting larger, delayed payoffs, both Conflict and Wavering increased suggesting that controlling the temptation of selecting the sooner, smaller reward entails effort. By analyzing trajectories, the study advances knowledge of the construct validity of different action dynamic measures and supports the distinction of decision uncertainty and decision conflict.

For effective human-robot interaction, we argue that robots must gain social-cognitive mechanisms that allow them to function naturally and intuitively during social interactions with humans. However, a lack of consensus on social cognitive processes poses a challenge for how to design such mechanisms for artificial cognitive systems. We discuss a recent integrative perspective of social cognition to provide a systematic theoretical underpinning for computational instantiations of these mechanisms. We highlight several commitments of our approach that we refer to as Engineering Human Social Cognition. We then provide a series of recommendations to facilitate the development of the perceptual, motor, and cognitive architecture for this proposed artificial cognitive system in future work. For each recommendation, we highlight their relation to the discussed social-cognitive mechanisms, provide the rationale for these recommendations and potential benefits, and detail examples of associated computational formalisms that could be leveraged to instantiate our recommendations. Overall, the goal of this paper is to outline an interdisciplinary and multi-theoretic approach to facilitate the design of robots that will one day function, and be perceived, as socially interactive and effective teammates.  相似文献

For Jacob A. Arlow, understanding unconscious fantasies was central to his clinical work. These fantasies are to be found at the core of those eruptions that break without warning into our ordinary lives, whether in the form of hysterical symptoms, daydreams or nightmares. What, however, could an unconscious fantasy be on a theoretical level, beyond a vehicle for discharge? Although partly unconscious, such fantasies are sometimes composed of fixed verbal content with a high degree of internal organisation. Unconscious fantasies therefore pose many challenges to understanding.  相似文献

The purpose of this paper is to write about insights and special considerations for researchers who are, to some degree, “insiders” to the communities they study by expanding on the concept of representational ethics as applied to research in community psychology with diverse and marginalized groups. Representational ethics refers to the ways that researchers, artists, or corporations represent the identities of the people they portray in their communications. As community psychologists we generate and disseminate knowledge about the communities we work with, and in that process, create narratives about the people who participate in our studies. In preparing a report on psychological issues among Evangelical Christian refugees from the former Soviet Union, Dina Birman struggled with her portrayal of this group and her own status of being both an insider and an outsider to this community. When investigating academic aspirations and psychological distress among Muslim high school students, Ashmeet Oberoi was forced to acknowledge the one‐sidedness of the discourse on autonomy and cultural socialization of Muslim adolescents. In her research with Cuban‐educated doctors in Miami, Florida, Wendy Moore encountered similar issues as she considered how to represent gender dynamics among her participants.  相似文献

Emotional inertia is a central feature of emotion dynamics and it refers to the degree to which emotional states are self-predictive and linger over time, describing their resistance to change. It is related to several indicators of maladjustment, yet there is limited research on its correlates in the workplace, where it may be particularly relevant as emotional experiences deeply influence organizational life. In two experience-sampling studies, we studied temporal dependency of negative emotional states at work in terms of emotional inertia. In a first study (n = 128), we investigated the association between exhaustion, the core dimension of burnout, with inertia of negative emotions. In a second study (n = 116), we aimed to replicate findings from the first study and additionally examined the moderating role of inertia of negative emotions in the relationship between negative emotions at work and counterproductive work behaviour. The findings show that exhaustion is consistently associated with inertia of negative emotions, and that inertia of negative emotions aggravates the relation between negative emotions and workers' counterproductive work behaviour.  相似文献

Recently, social identity approach has been giving stimulating insights in leadership in sport, considering social identification as a consequence regarding leadership processes. Nonetheless, social identity theory fundamentally posits social identification as a subjacent parameter of cognitions implied in the frame of interpersonal and intergroup relations. The current study aimed to enrich the existing literature by investigating athletes’ team identification as a predictor of the perception of coach-created climate. French male rugby union players (N = 248) completed an online survey measuring the multidimensionality of their social identification to the team, and their perception of the coach-created climate in terms of empowering and disempowering motivational climate. Using Group Actor-Partner Interdependence Modelling, the analyses revealed that the perception of the climate as empowering was driven by high scores on ingroup ties, especially when teammates’ ingroup ties scores were low. Team’s ingroup affect and cognitive centrality resulted in lower perception levels of the empowering climate. Neither player's ingroup ties nor cognitive centrality predicted the perception of the climate as empowering, and when player’s ingroup affect fitted into the group, his perception of a disempowering motivational climate decreased when ingroup affect score was high. The results are mainly discussed to the light of intergroup permeability by underlying the importance of considering social identification as a predictor of the perception of coach-athletes’ relationship. Some practical applications are put forward along with future directions for research on coach-athletes’ relationship. Especially, this study points out the importance of considering the social identity approach of leadership as a transactional relationship encapsulated in a mutual influence between the ingroup member social identification and that of the team as a whole.  相似文献

Female recreational runners are 2–3 times more likely to suffer from knee injury compared with male runners. However, the exact reason for this gender difference regarding knee injury remains unclear. Our study aimed to investigate gender differences in coordination variability between shank and rearfoot during running using statistical parametric mapping (SPM). Eleven healthy males and eleven healthy females ran on a treadmill. A modified vector coding technique procedure was used to create joint coupling between shank internal/external rotation and rearfoot eversion/inversion. The standard deviation of each coupling was computed as a measure of coordination variability during the stance phase. All trajectory data of coordination variability between genders were analyzed using a two-sample t-test of SPM. No differences in the normalized spatiotemporal parameters of speed, cadence and step length were found between males and females. SPM showed no significant differences between the genders in coordination variability. This study demonstrated that coordination variability between the shank and rearfoot during running may not be associated with the different incidence rates of knee injuries among male and female participants.  相似文献

Motion sickness is preceded by differences in the quantitative kinematics of body sway between individuals who (later) become sick and those who do not. In existing research, this effect has been demonstrated only in measures of body sway, relative to the earth. However, body sway can become coupled with imposed oscillatory motion of the illuminated environment, and the nature of this coupling may differ between individuals who become sick and those who do not. We asked whether body sway would become coupled to complex oscillations of the illuminated environment, and whether individual differences in such coupling might be precursors of motion sickness. Standing participants (women) were exposed to complex oscillation of the illuminated environment. We examined the strength of coupling as a function of time during exposure. Following exposure, some participants reported motion sickness. The nature and temporal evolution of coupling differed between participants who later reported motion sickness and those who did not. Our results show that people can couple the complex dynamics of body sway with complex imposed motion, and that differences in the nature of this coupling are related to the risk of motion sickness.  相似文献

Walking is one of the fundamental forms of human gross motor activity in which spatiotemporal movement coordination can occur. While considerable body of evidence already exists on pedestrian movement coordination while walking in pairs, little is known about gait control while walking in more complex topological arrangements. To this end, this study provides some of the first evidence of spontaneous gait synchronisation while walking in a group. Nine subjects covered the total distance of 40 km at different speeds while assembled in a three-by-three formation. Two experimental protocols were applied in which the subjects were either not specifically asked to or specifically asked to synchronise their gait. To obtain results representative from the point of view of gait control, the movement coordination was quantified using the indirectly measured vertical component of ground reaction force, based on output from a network of wireless motion monitors. Bivariate phase difference analysis was conducted using wavelet transform, synchronisation strength measures derived from Shannon entropy, and circular statistics. A fundamental relationship describing the influence of the group walking speed on individuals’ pacing frequency was established, showing a positive correlation different from that previously reported for walking in solitude. A positive correlation was found between the average synchronisation strength within a group and group’s walking speed. The most persistent coordination patterns were identified for pedestrians walking front-to-back and side-by-side. Overall, the spontaneous gait synchronisation while walking in a group is relatively weak, well below the levels reported for walking in pairs.  相似文献

Objective: How can we distinguish between a collection of individuals exercising alongside one another from group that is exercising ‘together’? This question is central to research on the extent that individuals perceive their fitness settings to entail core features of groups. To advance understanding of the nature of groupness and its implications in exercise, the current study (a) evaluated a brief measure of groupness and (b) examined the extent that groupness predicted perceptions of exertion and affect.

Design: Participants included 633 exercisers (M_age?=?33.92, SD?=?11.05, 74% female) who completed surveys after group fitness classes (k?=?34).

Main outcome measures: Groupness, affect, exertion, and group cohesion.

Results: Exploratory structural equation modelling provided support for a two-factor solution reflecting entitativity and group structure as subdimensions of groupness. The groupness factors were differentially associated with theoretically relevant aspects of classes (e.g. synchronised movement), the individual (e.g. number of members interacted with), as well as group cohesion. Groupness also predicted perceived exertion and affect.

Conclusion: Our research provides support for a brief measure of groupness, advances theory related to how individuals perceive exercise groups, and provides evidence regarding how broader experiences during exercise may relate to exercisers’ perceptions of groupness.  相似文献
