The scientific approach to the study of creative problem-solving has shifted from using classic insight problems (e.g., the Nine-dots problem), toward sets of problems that have more robust psychometric properties, such as the Remote Associate Test (RAT). Because it is homogeneous, compact, quickly solvable, and easy to score, the RAT has been used more frequently in recent creativity studies. We applied the Item Response Theory (IRT) to develop an Italian version of this task. The final 51-item test was reliable (α = .89) and provided information over a wide range of ability levels, as revealed by the IRT analysis. The RAT correlated with five measures of creative performance: The Raven's Standard Progressive Matrices (SPM), three classic insight problems, a set of anagrams purposefully developed, the fluency and flexibility scores of the Alternative Uses Task (AUT), and the Creative Achievements Questionnaire (CAQ). The new measure provided is meant to encourage the study of creativity and problem-solving in the Italian language. 相似文献

The representation of time and space are closely linked in the cognitive system. Optokinetic stimulation modulates spatial attention in healthy subjects and patients with spatial neglect. In order to evaluate whether optokinetic stimulation could influence time perception, a group of healthy subjects performed "time-comparison" tasks of sub- and supra-second intervals before and after leftward or rightward optokinetic stimulation. Subjective time perception was biased by the direction of optokinetic stimulation. Rightward optokinetic stimulation induced an overestimation of time perception compared with baseline and leftward optokinetic stimulation. These results indicate a directional bias in time perception induced by manipulation of spatial attention and could argue for a mental linear representation of time intervals. 相似文献

When a hand (either real or fake) is stimulated in synchrony with our own hand concealed from view, the felt position of our own hand can be biased toward the location of the seen hand. This intriguing phenomenon relies on the brain's ability to detect statistical correlations in the multisensory inputs (ie visual, tactile, and proprioceptive), but it is also modulated by the pre-existing representation of one's own body. Nonetheless, researchers appear to have accepted the assumption that the size of the seen hand does not matter for this illusion to occur. Here we used a real-time video image of the participant's own hand to elicit the illusion, but we varied the hand size in the video image so that the seen hand was either reduced, veridical, or enlarged in comparison to the participant's own hand. The results showed that visible-hand size modulated the illusion, which was present for veridical and enlarged images of the hand, but absent when the visible hand was reduced. These findings indicate that very specific aspects of our own body image (ie hand size) can constrain the multisensory modulation of the body schema highlighted by the fake-hand illusion paradigm. In addition, they suggest an asymmetric tendency to acknowledge enlarged (but not reduced) images of body parts within our body representation. 相似文献

Objective
The IZOF-based probabilistic approach provides a methodology to study within-individual patterns of a performer's states. So far, the time course of physiological data before performance have not been investigated within the probabilistic methodology framework. The purpose of this study was to examine the value of the probabilistic approach in the assessment of the time course of physiological indicators of arousal/activation and vigilance during the period preceding the shot, in comparison with the performance-based method.Design
Longitudinal assessment of psycho-physiological data and performance outcomes was conducted on eight elite pistol shooters in a controlled setting.Methods
Each participant performed 60 air-pistol shots in 2 sessions. Skin conductance level and cardiac activity were recorded. Affective states intensity was evaluated on a modified 11-point Borg scale. Affect, HR and SC level were evaluated with a Performance-based approach and a Probabilistic method, and results compared at an individual level.Results
Findings showed the higher effectiveness of the probabilistic method to analyse physiological parameters (skin conductance and heart rate) and to describe the physiological mechanisms associated with shooters’ performance.Conclusions
The probabilistic method better discerned the contribution of arousal/activation and vigilance to optimal and non-optimal performance in elite shooters, thereby providing a sharper representation of the temporal pattern of performers' states before shooting. From an applied perspective, we believe that the probabilistic approach can help athletes become aware of the subtle variations occurring in their psychophysical states during the preparatory period preceding the shot and not only at the moment of shot release. 相似文献48.
Parents’ view of the quality of early childhood education and care services has mostly been addressed from the perspective of customer satisfaction. This study investigated parents’ view within a more comprehensive framework in which parents’ values of child care, their evaluations of their child’s experience at the service and overall satisfaction with the service were considered. In particular, the study explored how values and evaluations are related and how they affect overall satisfaction. A questionnaire including a total of 96 items was filled in by 2,936 parents of children attending infant-toddler day-care centres in Rome, Italy. Parents were asked to express their values regarding child care quality and evaluate specific aspects of their experience. Parents’ perspectives of both their child’s and their own experience of childcare services were addressed separately. Two principal component analyses were performed in order to identify latent dimensions underlying parents’ values about child care quality and their evaluations of the service attended by their child. The relationships between the different dimensions of value, evaluation, and overall satisfaction with their child’s and their own experience were explained through two path models, in which values predict evaluations and these, in turn, predict overall satisfaction. Results showed that parents have a multi-faceted view of child care quality and confirm the relevance of taking into account their point of view in an analysis of the quality of early childhood education services. 相似文献

Working memory decay in advanced age has been attributed to a concurrent decrease in the ability to control interference.
The present study contrasted a form of interference control in selective attention that acts upon the perception of external
stimuli (access) with another form that operates on internal representations in working memory (deletion), in order to determine
both of their effects on working memory efficiency in younger and older adults. Additionally, we compared memory performance
under these access and deletion functions to performance in their respective control conditions. The results indicated that
memory accuracy improved in both age groups from the access functions, but that only young adults benefited from the deletion
functions. In addition, intrusion effects in the deletion condition were larger in older than in younger adults. The ability
to control the irrelevant perception- and memory-elicited interference did not decline in general with advancing age; rather,
the control mechanisms that operate on internal memory representations declined specifically. 相似文献
