Robert J. Sternberg 《创造性行为杂志》2020,54(2):229-241
This article describes a “straight-A” model of the creative process. It characterizes the creative process in five overlapping phases, with the variables most affecting those phases characterized as: (1) activators, (2) abilities, (3) amplifiers, (4) appeal to audience, and (5) assessment by audience. The creative process does not complete itself often, in part because all five phases rarely work in the right direction. For example, at Phase 1, there are deactivators as well as activators and at Phase 3, there are attenuators of creativity as well as amplifiers. I further discuss in the article the implications of the model for the relation between creativity and intelligence. In particular, whereas aspects of intelligence (according to the triarchic theory of successful intelligence) involve some degree overlap among creative, analytical, and practical skills, true creativity involves a true conjunction of these skills and is therefore much rarer. 相似文献

Key issues in the behavioral sciences are if there exist stable risk preferences that generalize across domains and if these are best measured by revealed risk preference (RRP) in behavioral decision tasks or by surveys eliciting stated risk preference (SRP). We applied network analysis to data from a representative Swedish sample to investigate the relations between RRP, SRP, personality characteristics, and cognitive abilities, using in total over 70 measurements. The results showed that different measures of RRP were poorly intercorrelated and formed a community together with measures of numerical and cognitive abilities. Measures of SRP were weakly correlated with measures of RRP and identified in a distinctly separate community, along with personality characteristics and gender. The ensuing analyses provided support for a model suggesting that RRPs are contaminated by demands on numerical and cognitive abilities. RRPs may thus suffer from poor construct validity, whereas SRPs may better capture people's everyday risk preferences because they are related to more stable traits. 相似文献

For the fixed-effects three-parameter logistic model in item response theory, the necessary and sufficient condition of the model identification is presented synthesizing known results. An optimal transformation of parameters for model identification in Maris's unidentified case to remove or reduce the skewness of abilities is shown. In many cases, the vanishing skewnesses are obtained in the possible range of transformation for parameters with some improvements in the test response and information functions. 相似文献

Sex differences in cognitive abilities were determined using the norms from two standardizations of the Differential Aptitude Test (DAT) and the Primary Mental Abilities (PMA) conducted between 1979 and 1995 in Spain. The standardized sex differences (ds) were computed separately for the DAT and the PMA subscales. Males scored higher in the DAT subscales Verbal Reasoning, Numerical Ability, Spatial Relations and Mechanical Reasoning, as well as in the PMA subscales Numerical Ability and Mental Rotation. Females scored higher in Inductive Reasoning (PMA-R) in the 1979 and 1995 standardizations. Taken together, these data do not support the hypothesis that cognitive sex differences are disappearing: there are still some differences favoring females and still some differences favoring males. 相似文献

Two series of experiments investigated factors affecting utterance of food calls in the domestic hen, Gallus domesticus. The first series of experiments tested the effect of food preference and the hen’s internal state on the utterance of food
calls. Different food types were presented first singly and then in a choice test to 20 hens, first when hens were laying,
and then when they were maternal. The second series of experiments tested the effect of hunger level on the utterance of food
calls in laying hens, and maternal hens with or without chicks. These two series of experiments showed that laying hens and
maternal hens showed a similar marked preference for certain types of food, but laying hens very rarely emitted food calls,
in contrast to maternal hens. This shows the effect of the bird’s psychophysiological state on her tendency to emit food calls.
The more a maternal hen preferred a food type, the more food calls she emitted. This was observed from the beginning of a
test in single-food tests as well as in choice tests. Hunger level positively affected food-call production under certain
feeding conditions in maternal hens, but not in laying hens. When maternal hens were tested in the absence of their chicks,
utterance of food calls was more sustained than in the presence of chicks.

幼儿心理理论与情绪理解发展及关系的研究 总被引:11,自引:2,他引:9
本研究采用横断设计,以北京市某幼儿园大、中、小班共98名幼儿为被试,通过对其心理理论、情绪理解及语言能力的测试,考察幼儿心理理论和情绪理解的发展状况以及二者之间的关系。研究结果表明:(1)幼儿的心理理论和情绪理解在3~5岁期间发生了巨大的变化,在5岁的时候大多数的幼儿已经基本上具备了心理理论和情绪理解的能力,4岁是幼儿心理理论和情绪理解能力发展的关键年龄;(2)幼儿的心理理论和情绪理解的相关显著,即使在控制了语言和年龄的影响后,心理理论能力仍然和情绪理解能力在总体上相关显著;(3)在排除了语言和年龄的影响后,对他人错误信念的理解能力和情绪观点采择能力的相关也仍然显著。 相似文献

Within preterm-born children, being born male and at a lower gestational age (GA) have both been associated with a heightened risk for developmental difficulties. However, in this population little is known about the combined effect and the influence of these risk factors on cortical structures and executive control. In the present study, 58 preterm-born children (GA ranging from 24.0 to 35.1 weeks) were administered the computerized Child Attention Network Task at 6 years of age. Brain magnetic resonance imaging was performed and analyzed using Voxel-Based Morphometry (VBM) in all children. At a behavioral level, boys born <28 weeks of GA had significantly less executive control than preterm-born girls <28 weeks (p = .001) and preterm-born boys ≥28 (p = .003). The reduced executive control in preterm-born boys <28 weeks gestation was related to lower cortical densities in the inferior frontal gyrus (IFG) and dorsolateral prefrontal cortex (DLPFC). The current study links the higher incidence of reduced executive control in preterm-born boys to a higher degree of prematurity (low GA) and identifies brain structural abnormalities in the prefrontal cortex related to these deficits. The implications of these results are discussed. 相似文献

It is well established that smoking is associated with impaired mental health and sleep problems. However, the possible effects of passive smoking on cognitive and emotional characteristics have not previously been evaluated in adolescents. We investigated the association between passive smoking and cognitive and emotional function, and sleep patterns in 940 adolescent girls. The girls were divided into two groups [305 exposed subjects and 635 non-exposed subjects (the controls)]. The passive smokers had a significantly lower cognitive function and higher depression, aggression, and insomnia scores compared to the control group (P?<?0.05). No significant difference was detected with respect to day-time sleepiness and sleep apnea. Logistic regression analyses showed that the passive smokers were more likely than the controls to have cognitive impairments, depressive mood, aggressive behavior, and insomnia. Adolescent passive smokers had significant differences in their cognitive abilities and emotional function. 相似文献

The American and Canadian standardization samples for the fourth edition of the Wechsler Intelligence Scale for Children were
used to ascertain the prevalence of “seemingly anomalous” Full Scale IQ (FSIQ) scores for all possible sums of scaled scores
combinations of the Verbal Comprehension Index, Perceptual Reasoning Index, Working Memory Index, and Processing Speed Index.
About 1% of FSIQ scores in both samples were anomalous (that is, fell outside the range of the four indices). Interestingly,
the prevalence of anomalous scores was higher at the extremes of the FSIQ distribution. Moreover, anomalous FSIQ scores occurring
above or below the mean of the FSIQ distribution (that is, 100) were larger or smaller, respectively, than any of the four
indices. Furthermore, if the range of the four indices did contain the FSIQ (the non-anomalous case), when the FSIQ was below
or above 100 it tended to be located distally in the half-segment of the range furthest below or above 100, respectively.
A non-technical intuitive analogy from Olympic sports and a statistical explanation for the findings are provided. Important
implications for practitioners are also presented.
