Research suggests that perceptual experience of our movements adapts together with movement control when we are the agents of our actions. Is this agency critical for perceptual and motor adaptation? We had participants view cursor feedback during elbow extension–flexion movements when they (1) actively moved their arm, or (2) had their arm passively moved. We probed adaptation of movement perception by having participants report the reversal point of their unseen movement. We probed adaptation of movement control by having them aim to a target. Perception and control of active movement were influenced by both types of exposure, although adaptation was stronger following active exposure. Furthermore, both types of exposure led to a change in the perception of passive movements. Our findings support the notion that perception and control adapt together, and they suggest that some adaptation is due to recalibrated proprioception that arises independently of active engagement with the environment. 相似文献

The functional MRI (fMRI) community has zealously embraced resting state or intrinsic functional connectivity approaches to mapping brain organization. Having demonstrated their utility for charting the large-scale functional architecture of the brain, the field is now leveraging task-independent methods for the investigation of phenotypic variation and the identification of biomarkers for clinical conditions. Enthusiasm aside, questions regarding the significance and validity of intrinsic brain phenomena remain. Here, we discuss these challenges and outline current developments that, in moving the field toward discovery science, permit a shift from cartography toward a mechanistic understanding of the neural bases of variation in cognition, emotion and behavior. 相似文献

Though people in positions of power have many advantages that sustain their power, stories abound of individuals who fall from their lofty perch. How does this happen? The current research examined the role of illusions of alliance, which we define as overestimating the strength of one’s alliances with others. We tested whether powerholders lose power when they possess overly positive perceptions of their relationships with others, which in turn leads to the weakening of those relationships. Studies 1 and 2 found that powerful individuals were more likely to hold illusions of alliance. Using laboratory as well as field contexts, Studies 3, 4, and 5 found that individuals with power who held illusions of alliance obtained fewer resources, were excluded more frequently from alliances, and lost their power. These findings suggest that power sometimes leads to its own demise because powerful individuals erroneously assume that others feel allied to them. 相似文献

Samples used in sales force research studies found in JM, JMR, JPSSM, and IMM over a seventeen year period were examined to discover the extent to which sales force sampling has met the issues of covering different industries and types of salespeople, of satisfying technical sampling requirements, and of clearly reporting on sampling methods. Recommendations for improving standards for conducting and reporting sales force sampling methodology in terms of the resources available are offered. 相似文献

The present study examined the antecedents of trust among operational Air Force fighter pilots for an automatic ground collision avoidance technology. This technology offered a platform with high face validity for studying trust in automation because it is an automatic system currently being used in operations by the Air Force. Pilots (N = 142) responded to an online survey which asked about their attitudes toward the technology and assessed a number of psychological factors. Consistent with prior research on trust in automation, a number of trust antecedents were identified which corresponded to human factors, learned trust factors, and situational factors. Implications for the introduction of novel automatic systems into the military are discussed. 相似文献

Jack’s (1991) theory of self-silencing was originally designed to explain higher rates of depression in women in comparison to men. However, research finding that men score equal or even higher than women on measures of self-silencing has lead theorists to speculate that self-silencing tendencies may be driven by different motivations and have different consequences for women versus men (Jack & Ali, 2010). Using a sample of 247 college students, we examined gender differences in the construct validity of the Silencing the Self Scale (STSS; Jack & Dill, 1992). We hypothesized that women would score higher on the Externalized Self-Perception subscale, but not the other three subscales. Gender differences in the relationship between the STSS subscales and theoretically-relevant constructs were also explored. The results indicated that women on average scored higher than men on the Externalized Self-Perception subscale, whereas men scored higher on the Care as Self-Sacrifice subscale. Further, there was a significant Gender × Care as Self-Sacrifice subscale interaction in the prediction of depression, such that this subscale was negatively correlated to depression in men, and uncorrelated in women. These results clarify how self-silencing might translate into different mental health outcomes for women and men. 相似文献

This scholarly essay employs an African philosophical and symbolic construct—Sank?fa—to examine religious education in Ghana. Sank?fa implores the need to examine the past in order to understand the present and to plan for the future. In line with this frame, I recount the history of religious education in Ghana, examine the present challenges, and explore new ways of making Christian Religious Education relevant to contemporary challenges in education. 相似文献

Five male undergraduates could earn 4¢ for every 200 knob-pulls. In addition, they could avoid or terminate an aversive tone by pressing a button with a force of 1.5 lbs (nonaggressive response) or by hitting a cushion with at least 20 lbs force (aggressive response). Rates of aggression tended to be higher during sessions where money was taken from the Ss at the rate of 1¢ per 12 seconds than during sessions when taking was not in effect. Rates of nonaggressive responses were constant across conditions. 相似文献

The entire available population (N = 408) of a primary school in Perth, Western Australia, was tested for eideticism using a slightly modified presentation of the Haber and Haber (1964) procedure. Sixteen eidetikers were found in the age range covered (5–13 years). When classified into four age categories (5–6, 7–8, 9–10, 11–13), the number of eidetikers in relation to noneidetikers showed a statistically significant and systematic decline with increasing age. These results are discussed in relation to their possible significance for a theory of eidetic development. 相似文献
