The formation of associations between objects and locations is a vital aspect of episodic memory. More specifically, remembering the location where one experienced an object and, vice versa, the object one encountered at a specific location are both important elements for the memory of an event. Whether episodic associations are holistic representations of individual components or whether there are unidirectional, separately modifiable connections between them has been investigated nearly exclusively using verbal stimuli. A preliminary conclusion concerning this controversy is that verbal associations are, at least, highly correlated (M. J. Kahana, 2002). This theoretical debate, which in the past has undergone a major empirical effort, is still of relevance for the concurrent global matching models of associative memory (S. E. Clark & S. D. Gronlund, 1996). The authors used variations of a novel object-location learning paradigm to complement the accumulated evidence regarding the nature of episodic associations. 相似文献

This paper reports the results of a two-sample study—a sample of medical reps from pharmaceutical companies (N = 232) and a sample of respondents from multiple organizations (N = 221)—of the relationships between pay satisfaction, organizational commitment, and turnover intentions. Hypotheses were
tested using a multidimensional perspective on both pay satisfaction and organizational commitment. Results from both samples
show that the effect of pay satisfaction on intended turnover is fully mediated by affective commitment and perceived sacrifice
commitment. Pay satisfaction is also significantly related to normative commitment but the latter has no influence on the
outcome. Finally, in the sample of medical reps, pay satisfaction significantly reduces commitment based on lack of employment
alternatives, a finding that is interpreted in light of the characteristics of pay systems in pharmaceutical companies. Future
directions on compensation satisfaction and commitment research are discussed. 相似文献

Researchers realize that motor imagery (MI) duration is closely linked to actual motor action duration. In 2 experiments, the authors investigated the effect of changing MI speed on actual movement duration over a 3-week training period. Experiment 1 involved 2 series of body movements that 24 participants mentally performed faster or slower than their actual execution speeds. The fast MI group's actual times decreased on subsequent performance. Participants in Experiment 2 were 21 skilled athletes who increased (decreased) their well-rehearsed actual movement times after MI training at a slow (fast) speed. The effect was task-related, however: MI affected only self-initiated movement. The effect of MI on actual speed execution supports the ideomotor theory because anticipation of sensory consequences of actions is mentally represented. 相似文献

Renewal of an extinguished conditioned response has been demonstrated in humans and in animals using various types of procedures, except renewal of motor learning such as eyeblink conditioning. We tested renewal of delay and trace eyeblink conditioning in a virtual environment in an ABA design. Following acquisition in one context (A, e.g., an airport) and extinction in a different context (B, e.g., a city), tests for renewal took place in the acquisition (A) and extinction context (B), in a counterbalanced order. Results showed renewal of the extinguished conditioned response in the delay but not trace condition. 相似文献

Zuidas is a new city centre, which is emerging in the outskirts of Amsterdam. The ambitious project of developing a new international
city centre has been carefully planned as the Netherlands has a strong and meticulous tradition for urban planning. The planning
has however not only encompassed traditional urban planning aspects such as infrastructure, environmental factors and aesthetics,
but has also dealt with the design of urban experiences. Through an introduction of the framework of the structure of experiences,
this article examines how urban experiences can be understood and analysed, and deals with how urban experiences can be designed
through careful consideration of how experiences are constituted. Taking the psychological structure of experiences into account
when designing urbanity is not only interesting, but also highly relevant as Zuidas is competing with other international
venues such as La Défense, the Docklands and Potsdamer Platz. 相似文献

The feedback-related negativity (FRN) and the P300 have been related to the processing of one’s own and other individuals’ feedback during both active and observational learning. The aim of the present study was to elucidate the role of trait-empathic responding with regard to the modulation of the neural correlates of observational learning in particular. Thirty-four healthy participants completed an active and an observational learning task. On both tasks, the participants’ aim was to maximize their monetary gain by choosing from two stimuli the one that showed the higher probability of reward. Participants gained insight into the stimulus–reward contingencies according to monetary feedback presented after they had made an active choice or by observing the choices of a virtual partner. Participants showed a general improvement in learning performance on both learning tasks. P200, FRN, and P300 amplitudes were larger during active, as compared with observational, learning. Furthermore, nonreward elicited a significantly more negative FRN than did reward in the active learning task, while only a trend was observed for observational learning. Distinct subcomponents of trait cognitive empathy were related to poorer performance and smaller P300 amplitudes for observational learning only. Taken together, both the learning performance and event-related potentials during observational learning are affected by different aspects of trait cognitive empathy, and certain types of observational learning may actually be disrupted by a higher tendency to understand and adopt other people’s perspectives. 相似文献

Model-based calculations indicate that reflex delay and reflex gain are both important for spinal stability. Experimental results demonstrate that chronic low back pain is associated with delayed muscle reflex responses of trunk muscles. The aim of the present study was to analyze the influence of such time-delayed reflexes on the stability using a simple biomechanical model. Additionally, we compared the model-based predictions with experimental data from chronic low back pain patients and healthy controls using surface-electromyography. Linear stability methods were applied to the musculoskeletal model, which was extended with a time-delayed reflex model. Lateral external perturbations were simulated around equilibrium to investigate the effects of reflex delay and gain on the stability of the human lumbar spine. The model simulations predicted that increased reflex delays require a reduction of the reflex gain to avoid spinal instability. The experimental data support this dependence for the investigated abdominal muscles in chronic low back pain patients and healthy control subjects. Reflex time-delay and gain dependence showed that a delayed reflex latency could have relevant influence on spinal stability, if subjects do not adapt their reflex amplitudes. Based on the model and the experimental results, the relationship between muscle reflex response latency and the maximum of the reflex amplitude should be considered for evaluation of (patho) physiological data. We recommend that training procedures should focus on speeding up the delayed reflex response as well as on increasing the amplitude of these reflexes. 相似文献

Drawing on decades of research suggesting an attentional advantage for self‐related information, researchers generally assume that self‐related stimuli automatically capture attention. However, a literature review reveals that this claim has not been systematically examined. We aimed to fill in this dearth of evidence. Following a feature‐based account of automaticity, we set up four experiments in which participants were asked to respond to a target preceded by a cue, which was self‐related or not. In Experiment 1, larger cuing effects (faster reaction times to valid versus invalid trials) were found with a participant's own name compared with someone else's name. In Experiment 2, we replicated these results with unconscious cues. Experiment 3 suggested that these effects are not likely driven by familiarity. In Experiment 4, participants experienced greater difficulties from having their attention being captured by their own compared with someone else's name. We conclude that attentional capture by self‐related stimuli is automatic in the sense that it is unintentional, unconscious, and uncontrolled. Implications for self‐regulation and intergroup relations are discussed. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

The goal of this study was to develop a measure of creativity that builds on the strengths of youth with autism spectrum disorders (ASD). The assessment of creativity focused on the visual-spatial abilities of these youth using 3D modeling software. One of the objectives of the research was to develop a measure of creativity in an authentic learning environment that built on the interests and creative talents of youth with ASD. Traditional creativity tests may underestimate the creativity of youth with ASD because of the tests’ constrained nature, such as having a time limit, being limited to paper and pencil, testing in an over- or understimulating environment, and overlooking visual-spatial ability. A random selection of 27 student 3D design projects (out of approximately 100 projects) was assessed using dimensions of fluency, flexibility, originality, and elaboration. The validity of this assessment was examined by comparing the creativity scores of the 27 projects to the creativity scores given by a team of Google experts (3D designers and software engineers). Results indicated that the scores were significantly correlated for three of the four dimensions of the creativity assessment. There was high inter-rater reliability among coders (M = .82) using intra-class correlation (ICC). Results suggest that this assessment process could be used as a visual-spatial creativity measure for youth with ASD, as well as a creativity measure used by employers to determine real-world creative potential in their employees, particularly those with neurodiversity. 相似文献
