The aim of this study was to analyze the replicability of Zuckerman's revised Alternative Five-factor model in a French-speaking context by validating the Zuckerman-Kuhlman-Aluja Personality Questionnaire (ZKA-PQ) simultaneously in 4 French-speaking countries. The total sample was made up of 1,497 subjects from Belgium, Canada, France, and Switzerland. The internal consistencies for all countries were generally similar to those found for the normative U.S. and Spanish samples. A factor analysis confirmed that the normative structure replicated well and was stable within this French-speaking context. Moreover, multigroup confirmatory factor analyses have shown that the ZKA-PQ reaches scalar invariance across these 4 countries. Mean scores were slightly different for women and men, with women scoring higher on Neuroticism but lower on Sensation Seeking. Globally, mean score differences across countries were small. Overall, the ZKA-PQ seems an interesting alternative to assess both lower and higher order personality traits for applied or research purposes. 相似文献

This study aims to assess age differences between Judgments-of-learning (JOLs) and Feeling-of-knowing (FOKs) as they are typically studied. The novel contribution of the present study is a comparison between these two metacognitive judgments in a within subject design. Young and older adults were tested on their JOL accuracy and were asked to predict future recall during learning. All participants were also asked to predict future recognition of unrecalled items (FOK judgments). Results showed that although older adults had similar low levels of memory performance in the JOL task and in the FOK task, metacognitive impairments were only found on the resolution of FOKs. Furthermore, an analysis of covariance showed that age differences on memory performance explained the age effect observed on the FOK, thus supporting the memory constraint hypothesis (Hertzog et al., 2010). Results are discussed in relation to contemporary models of memory. 相似文献

The processing-speedtheory and the prefrontal-executivetheory are competing theories of cognitive aging. Here we used a theoretically and methodologically-driven framework to investigate the relationships among measures classically used to assess these two theoretical constructs. Twenty-eight young adults (18-32 years) and 39 healthy older adults (65-80 years) performed a battery of nine neuropsychological and experimental tasks assessing three executive function (EF) components: Inhibition, Updating, and Shifting. Rate of information processing was evaluated via three different experimental and psychometric tests. Partial correlations analyses suggested that 2-Choice Reaction Time (CRT) performance is a more pure measure of processing speed than Digit Symbol Substitution Test (DSST) performance in the elderly. Hierarchical regression analyses showed that, although measures of processing speed and EF components share mutual variance, each measure was independently affected by chronological age. The unique adverse effect of age was more important for processing speed than for EF. The processing-speed theory and the prefrontal-executive theory of cognitive aging were shown not to be mutually exclusive but share mutual variance. This implies the need to control for their mutual relationship before examining their unique potential role in the explanation of age-related cognitive declines. Caution has still to be taken concerning the tasks used to evaluate these theoretical constructs. 相似文献

The purpose of this study was to examine the meanings and timescale of self-cuttings in a cohort of 22 outpatients suffering from borderline personality disorder. Sixty-one events were recorded using the newly developed self-cutting-checklist (SCUC) designed to investigate the severity of self-cuttings, and intent to die, suicidal ideation, inner tension, sense of relief and anesthesia, and consequences associated with this behavior. We found that typical self-cuttings were associated with a decrease in inner tension and suicidal ideation. Moreover self-cuttings associated with a desire to die differentiated from those associated with no desire to die by significantly less reduction in inner tension. Finally, self-cuttings occurred significantly more often during evenings and nights than during daytime. In conclusion, self-cuttings can be reasonably addressed by self-report. Attention to specific issues such as intent to die and the time of the self-cuttings may improve the outcome of these particularly high-risk subjects. 相似文献

In coincidence‐timing studies, children have been shown to respond too early to slower stimuli and too late to faster stimuli. To examine this velocity effect, children aged 6, 7.5, 9, 10.5, and adults were tested with two different velocities in a prediction‐motion task which consisted of judging, after the occlusion of the final part of its path, the moment of arrival of a moving stimulus towards a specified position. A similar velocity effect, resulting in later responses for the faster velocities than for the slower, was found primarily in the three younger groups of children (for the longer occlusion conditions: 600–1,320 milliseconds). However, this effect was not seen in all children in these groups. Individual analyses showed that this velocity effect, when present, is linked to the use of distance rather than time information, or to the confusion between these in extrapolating the occluded trajectories. The tendency to use one type of information or the other is a good predictor of accuracy and variability in this task and a good indicator of the development stage of the participants. Across development, children tend to initially use distance information with poor accuracy but relative consistency in responses. In a second stage, they use time and distance information alternatively across trials trying to find a better source of information with still poor accuracy and now great variability. In a final stage, they use time information to reach consistency and accuracy in their responses. This chronology follows the stages proposed by Savelesbergh and Van der Kamp (2000) explaining development with an initial stage of ‘freezing’ non‐optimal relationships between information and movement, then a ‘freeing’ stage during which new solutions are searched for, and finally an ‘exploiting’ stage with an optimal relationship between information and movement. 相似文献

Education must be a central part of the building of Europe: because access to knowledge can overcome the dangers of exclusion, but also because education offers the key to citizenship and thereby to the future of Europe. 相似文献
