Construction tasks form a major part of children's play and can be linked to achievement in maths and science. However there is a lack of understanding of construction task ability and development. Therefore, there is little foundation for the applied use of construction tasks, such as in teaching or research, as there are no apparent methods for assessing difficulty. This empirical research identifies four construction task characteristics that impact on cognition and predict construction task difficulty in children aged 7–8 and 10–11 years and adults. The results also reveal a developmental trajectory in construction ability. The research provides a method to quantify, predict and control the complexity of construction tasks for future research and to inform applied use. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

People's self-perception biases often lead them to see themselves as better than the average person (a phenomenon known as self-enhancement). This bias varies across cultures, and variations are typically explained using cultural variables, such as individualism versus collectivism. We propose that socioeconomic differences among societies--specifically, relative levels of economic inequality--play an important but unrecognized role in how people evaluate themselves. Evidence for self-enhancement was found in 15 diverse nations, but the magnitude of the bias varied. Greater self-enhancement was found in societies with more income inequality, and income inequality predicted cross-cultural differences in self-enhancement better than did individualism/collectivism. These results indicate that macrosocial differences in the distribution of economic goods are linked to microsocial processes of perceiving the self. 相似文献

Achterberg and colleagues conclude there is in train a significant change toward deprivatization in Europe. In the late 1990s Christians were more pro public religion in countries where they were least numerous and in the Netherlands in particular there had been an increasing difference in attitudes between believers and nonbelievers over 25 years. Examining more recent survey data on British attitudes (1998 and 2008), we find a firm consensus among the nonreligious against religion having a high public profile, while Christians are more likely to object to antireligion sentiment and people belonging to non‐Christian religions are more likely to support public religion. Nonreligious people appear to be no more hostile now than in the late 1990s, and where there has been a decrease in sympathy for public religion it is among religious groups. 相似文献

Although attentional control and memory change considerably across the life span, no research has examined how the ability to strategically remember important information (i.e., value-directed remembering) changes from childhood to old age. The present study examined this in different age groups across the life span (N = 320, 5-96 years old). A selectivity task was used in which participants were asked to study and recall items worth different point values in order to maximize their point score. This procedure allowed for measures of memory quantity/capacity (number of words recalled) and memory efficiency/selectivity (the recall of high-value items relative to low-value items). Age-related differences were found for memory capacity, as young adults recalled more words than the other groups. However, in terms of selectivity, younger and older adults were more selective than adolescents and children. The dissociation between these measures across the life span illustrates important age-related differences in terms of memory capacity and the ability to selectively remember high-value information. 相似文献

To improve understanding about genetic and environmental influences on antisocial behavior (ASB), we tested the association
of the 44-base pair polymorphism of the serotonin transporter gene (5-HTTLPR) and maltreatment using latent class analysis
in 2,488 boys and girls from Wave 1 of the National Longitudinal Study of Adolescent Health. In boys, ASB was defined by three
classes (Exclusive Covert, Mixed Covert and Overt, and No Problems) whereas in girls, ASB was defined by two classes (Exclusive
Covert, No Problems). In boys, 5-HTTLPR and maltreatment were not significantly related to ASB. However, in girls, maltreatment,
but not 5-HTTLPR, was significantly associated with ASB. A significant interaction between 5-HTTLPR and maltreatment was also
observed, where maltreated girls homozygous for the short allele were 12 times more likely to be classified in the Exclusive
Covert group than in the No Problems group. Structural differences in the latent structure of ASB at Wave 2 and Wave 3 prevented
repeat LCA modeling. However, using counts of ASB, 5-HTTLPR, maltreatment, and its interaction were unrelated to overt and
covert ASB at Wave 2 and only maltreatment was related to covert ASB at Wave 3. We discuss these findings within the context
of sex differences in ASB and relevant models of gene-environment interplay across developmental periods. 相似文献

与经验主义或实证主义之前的形式相比,逻辑和数学哲学是最具逻辑经验主义特征的。逻辑经验主义不仅因此得名,而且也为科学经验主义的成功点燃了希望。然而,经验主义者的心理主义与实证主义者的逻辑主义对数学本质的探讨始终不能达成共识。基于这种背景,维特根斯坦《逻辑哲学论》的发表对于维也纳小组的影响深远、意义重大。逻辑经验主义在20世纪20年代的数学哲学都是植根于《逻辑哲学论》的。本文在第一部分阐释了它何以成为该学派在"哲学上的转折点"。而维也纳学派从一开始就试图对《逻辑哲学论》进行革新,使之服务于其本身的纲领。本文在第二部分着重探讨了他们关于这些问题所展开的激烈讨论。这种状况一直持续到1931年卡尔纳普提出了"句法"纲领,该纲领从根本上超越了逻辑经验主义的原有框架。但由于当时欧洲逻辑经验主义者受到纳粹的迫害而四分五散,"句法"观点并未受到广泛关注。本文在第三、第四部分具体分析了逻辑经验主义如何由《逻辑哲学论》向"句法"思想转变的过程。 相似文献

The understanding of decision-making systems has come together in recent years to form a unified theory of decision-making in the mammalian brain as arising from multiple, interacting systems (a planning system, a habit system, and a situation-recognition system). This unified decision-making system has multiple potential access points through which it can be driven to make maladaptive choices, particularly choices that entail seeking of certain drugs or behaviors. We identify 10 key vulnerabilities in the system: (1) moving away from homeostasis, (2) changing allostatic set points, (3) euphorigenic "reward-like" signals, (4) overvaluation in the planning system, (5) incorrect search of situation-action-outcome relationships, (6) misclassification of situations, (7) overvaluation in the habit system, (8) a mismatch in the balance of the two decision systems, (9) over-fast discounting processes, and (10) changed learning rates. These vulnerabilities provide a taxonomy of potential problems with decision-making systems. Although each vulnerability can drive an agent to return to the addictive choice, each vulnerability also implies a characteristic symptomology. Different drugs, different behaviors, and different individuals are likely to access different vulnerabilities. This has implications for an individual's susceptibility to addiction and the transition to addiction, for the potential for relapse, and for the potential for treatment. 相似文献

The predictive validity of symptom criteria for different subtypes of ADHD among children who were impaired in at least one
setting in early childhood was examined. Academic achievement was assessed seven times over 8 years in 125 children who met
symptom criteria for ADHD at 4–6 years of age and in 130 demographically-matched non-referred comparison children. When intelligence
and other confounds were controlled, children who met modified criteria for the predominantly inattentive subtype of ADHD
in wave 1 had lower reading, spelling, and mathematics scores over time than both comparison children and children who met
modified criteria for the other subtypes of ADHD. In some analyses, children who met modified criteria for the combined type
had somewhat lower mathematics scores than comparison children. The robust academic deficits relative to intelligence in the
inattentive group in this age range suggest either that inattention results in academic underachievement or that some children
in the inattentive group have learning disabilities that cause secondary symptoms of inattention. Unexpectedly, wave 1 internalizing
(anxiety and depression) symptoms independently predicted deficits in academic achievement controlling ADHD, intelligence,
and other predictors. 相似文献

To estimate the prevalence of being well-adjusted in adolescence, boys and girls with (n = 96) and without (n = 126) attention-deficit/hyperactivity disorder (ADHD) were assessed seven times in eight years starting when they were 4–6 years
of age. Symptoms of ADHD, ODD/CD, and depression/anxiety in addition to social skills and social preference were gathered
using multiple methods and informants. Being well-adjusted was defined by surpassing thresholds in at least four of the five
domains. At the 7- and 8-year follow-up, when youth were 11–14 years old, probands were significantly less likely to be well-adjusted
relative to age- and ethnicity-matched control children. Only a minority of children with ADHD was well-adjusted in adolescence
when emotional, behavioral, and social domains were considered simultaneously. Even when their ADHD symptoms improved over
time, most probands exhibited significant impairment 7–8 years after their initial assessment. 相似文献

Real-world eyewitnesses are often asked whether their lineup responses were affected by various external influences, but it is unknown whether they can accurately answer these types of questions. The witness-report-of-influence mental-correction model is proposed to explain witnesses' reports of influence. Two experiments used a new paradigm (the actual/counterfactual paradigm) to examine eyewitnesses' abilities to report accurately on the influence of lineup manipulations. Eyewitnesses were administered either confirming feedback or no feedback (Experiment 1, n = 103), or a cautionary instruction or no cautionary instruction (Experiment 2, n = 114). Eyewitnesses then gave actual responses (retrospective confidence, view, and attention measures in Experiment 1; identification decision in Experiment 2) as well as counterfactual responses stating how they would have responded in the alternative condition. Results across both studies showed an asymmetric estimation of influence pattern: Eyewitnesses who received an influencing manipulation estimated significantly less of a change in their responses than eyewitnesses who did not receive an influencing manipulation. A 48-hr delay between actual and counterfactual responses did not moderate any effects. Results are explained by witnesses' implicit theories of influence. 相似文献
