Openness to experience is the broadest personality domain of the Big Five, including a mix of traits relating to intellectual curiosity, intellectual interests, perceived intelligence, imagination, creativity, artistic and aesthetic interests, emotional and fantasy richness, and unconventionality. Likewise, creative achievement is a broad construct, comprising creativity across the arts and sciences. The aim of this study was to clarify the relationship between openness to experience and creative achievement. Toward this aim, I factor analyzed a battery of tests of cognitive ability, working memory, Intellect, Openness, affect, and intuition among a sample of English Sixth Form students (N = 146). Four factors were revealed: explicit cognitive ability, intellectual engagement, affective engagement, and aesthetic engagement. In line with dual‐process theory, each of these four factors showed differential relations with personality, impulsivity, and creative achievement. Affective engagement and aesthetic engagement were associated with creative achievement in the arts, whereas explicit cognitive ability and intellectual engagement were associated with creative achievement in the sciences. The results suggest that the Intellectual and Openness aspects of the broader openness to experience personality domain are related to different modes of information processing and predict different forms of creative achievement.  相似文献

In 2 experiments, the influence of intention to process frequency on accuracy of memory for frequency of bizarre and common sentences was investigated. The results from multiple regression analyses indicated that intentional processing increased the accuracy of frequency judgments when memory for frequency was tested after a 2-min (Experiment 1) and after a 48-hr (Experiment 2) retention interval. Furthermore, the results of Experiment 2 indicated that unintentional processors tended to overestimate frequencies of bizarre relative to common items after a delay. The implications of the results are discussed with regard to L. Hasher and R. T. Zacks's (1984) automaticity hypothesis, human performance, and the accuracy of judgments of frequency of occurrence of unusual events.  相似文献

The present article represents an initial attempt to offer a principled solution to a fundamental problem of movement identified by Bernstein (1967), namely, how the degrees of freedom of the motor system are regulated. Conventional views of movement control focus on motor programs or closed-loop devices and have little or nothing to say on this matter. As an appropriate conceptual framework we offer Iberall and his colleagues’ physical theory of homeokinetics first elaborated for movement by Kugler, Kelso, and Turvey (1980). Homeokinetic theory characterizes biological systems as ensembles of non-linear, limit cycle oscillatory processes coupled and mutually entrained at all levels of organization. Patterns of interlimb coordination may be predicted from the properties of non-linear, limit cycle oscillators. In a set of experiments and formal demonstrations we show that cyclical, two-handed movements maintain fixed amplitude and frequency (a stable limit cycle organization) under the following conditions: (a) when brief and constantly applied load perturbations are imposed on one hand or the other, (b) regardless of the presence or absence of fixed mechanical constraints, and (c) in the face of a range of external driving frequencies from a visual source. In addition, we observe a tight phasic relationship between the hands before and after perturbations (quantified by cross-correlation techniques), a tendency of one limb to entrain the other (mutual entrainment) and that limbs cycling at different frequencies reveal non-arbitrary, sub-harmonic relationships (small integer, subharmonic entrainment). In short, all the above patterns of interlimb coordination fall out of a non-linear oscillatory design. Discussion focuses on the compatibility of these results with past and present neurobiological work, and the theoretical insights into problems of movement offered by homeokinetic physics. Among these are, we think, the beginnings of a principled solution to the degrees of freedom problem, and the tentative claim that coordination and control are emergent consequences of dynamical interactions among non-linear, limit cycle oscillatory processes.  相似文献

We collected data from a predominately Anglo American student sample in the Southeastern United States and a predominately Hispanic student sample in the Southwestern United States. Along with an assessment of internal consistency reliability, we examined measurement invariance of the Toronto Alexithymia Scale–20 (TAS–20) using confirmatory factor analysis. We also assessed the predictive invariance of the TAS–20. Results indicate that 2 of the 3 TAS–20 subscales demonstrated satisfactory internal consistency reliability across samples. Items from the TAS–20 subscales demonstrated measurement invariance of the latent means. The relationship between 2 measures of emotional dysfunction and the TAS–20 also demonstrated slope and intercept invariance, indicating equivalent validity.  相似文献

ABSTRACT

Criminologists have long theorized the relationship between race and crime using traditional criminological theories, suggesting that Blacks simply experience more factors conducive to crime than Whites. Race scholars have criticized this “add and stir” approach and, instead, argue for race-based explanations. Racialized General Strain Theory (RGST) is the first traditional approach to address this call to action. To date, however, little research has fully assessed RGST’s propositions. Using the Project on Human Development in Chicago Neighborhoods, we find mixed support for RGST. Findings also suggest racial differences in experiences and responses to strain are much more complicated than originally theorized.  相似文献

This study examines the extent to which male and female university students use verbal sexual coercion and physically forced sex on a dating partner and tests a theoretical model that specifies that corporal punishment, minor forms of neglect by parents, and sexual abuse increase the probability of sexually coercing and sexually assaulting a partner, and that this relationship is partly mediated by antisocial traits and behavior. A path analysis using multinomial logistic regression was used to test the fit of the model to a convenience sample of 13,877 students in 32 nations. Both male and female students perpetrate sexual coercion, but the rates are higher for males. For both men and women, each of the three forms of prior victimization studied were associated with an increased probability of antisocial behavior, which in turn was associated with an increased probability of verbally coercing and physically forcing sex. Most of the direct paths from victimization to sexual coercion were also statistically significant. Because relatively mild victimization such as corporal punishment and seemingly innocuous forms of neglect are highly prevalent, steps to reduce their prevalence could be an import step in primary prevention of sexual coercion.  相似文献

ABSTRACT

Offenders and nonoffenders possess valuable information about crime. But which possesses the best data? This is a complex issue, so I narrow my focus to data on empirical aspects of criminal events. Drawing on the necessary conditions perspective, I theorize that a source’s possession 1) of data varies directly with its involvement in cases; 2) of representative data varies inversely with nonrandom involvement in cases and nonrandom siphoning off from the larger group to which it belongs; and, 3) of accurate data varies inversely with time since involvement in cases. Those general principles suggest that offenders, especially active ones, possess the most data, representative data, and accurate data on empirical aspects of criminal events. I conclude by discussing the implications of those general principles for observation research, sources’ possession of subjective data, and their possession of empirical data on other criminological events, specifically victimization and policing.  相似文献

In today's penurious health care climate, occupational therapists must scrutinize their practice and substantiate their interventions in order to remain viable service providers. This article proposes a method of occupational therapy outcomes assessment in mental health care that is rooted in client-centered functional outcomes. Since little consensus exists on which instruments are most effective, this article begins with an outline of broadly accepted principles for assessment of patient outcomes in mental health. Next, we describe a practical method for selecting outcomes measures in interdisciplinary settings. Finally, we offer pragmatic solutions to address barriers to outcome assessment.  相似文献

This study examined the role of suppressor effects on age differences in anxious emotion. Children and adolescents (n = 1099) ages 7–18 years were assessed for separation anxiety, social anxiety, and generalized anxiety. Results of zero-order correlations indicated a significant negative association between age and separation anxiety but no association for social anxiety and generalized anxiety. However, semi-partial correlations indicated the presence of a cooperative suppressor effect such that the associations between age and social anxiety as well as age and generalized anxiety symptoms became significant and positive and the association with separation anxiety became larger in a simultaneous regression analysis of each facet with age. Similar effects occurred when controlling for hyperarousal in an ANCOVA across grade levels. Results suggest that attempts to understand developmental differences in anxious emotion in childhood and adolescence will be facilitated by parsing facets of anxious emotion and attention to potential suppressor effects.  相似文献
