The equivalence of an Internet administration of personality tests with two other administration formats was assessed using Item Response Theory (IRT) and various other statistical methods. The analyses were conducted on measures of Neuroticism, Extroversion, Agreeableness, and Conscientiousness. A total of 728 participants took part in the study. Participants were randomly assigned to one of three administrative conditions: paper-and-pencil, proctored computer lab, and unproctored Internet. Analyses with IRT, factor analysis, criterion-related validity, and mean differences supported the equivalence of Internet and traditional paper-and-pencil administrations of personality tests.  相似文献

Counting is often considered to be the coordination of two actions: saying the number-words and pointing to each object. We report three experiments to test the hypothesis that this coordination requires the use of the central executive (A. D. Baddeley, 1990), and that the cost of coordination decreases with age. Participants were 5- and 9-year-old children and adults. At all ages tested, the manipulation of the difficulty of each component affected counting performance but did not make coordination more difficult. These results suggest that, at least from the age 5, counting is a procedure in which the control of coordination is not attention demanding.  相似文献

The procedure generally used to diagnose aphasic patients consists of classifying them in one of the classic syndromes on the basis of the analysis of their symptoms. However, this taxonomy has several important problems, the main one being that it does not take into account the variability of aphasic patients, as there are many more disorder profiles than those included in the syndromes. In order to test the homogeneity of a sample of patients diagnosed with the classic taxonomy, 15 aphasic patients (5 Broca, 5 Wernicke and 5 Conduction) and 5 healthy controls were tested with nine comprehension and production tasks. Participants were aged 38 to 81 years old. The results indicate the existence of great variability in patients labeled with the same diagnosis, as revealed by the differences in within-group scores in each task, and a limited adjustment to the expected profile, with some patients showing symptoms allegedly corresponding to other syndromes. Our results call attention to the need to study each patient individually and interpret their disorders regardless of the syndromes.  相似文献

The present study tested the hypothesis that the linguistic complexity of pronouns corresponds to the order in which children acquire them. Linguistic complexity was defined by three principles of linguistic contrast, namely the proximal-nonproximal, singular-nonsingular, and speaker-nonspeaker contrasts.In an experimental naming task, 55 German children aged 3;5 to 6;5 were asked to express the possessive relationship between different participants in a communication situation and particular objects by means of personal pronouns in the dative case, used from the speaker's point of view. The results showed a strong correspondence between the predicted and actual order of correct use of pronouns, and provide evidence for the precedence of the proximal-nonproximal over the singular-nonsingular contrast.  相似文献

Jack-o-lanterns drawn by kindergarteners were submitted to adult judges who were asked both to identify the child's gender from the drawing and to give reasons for the judgment made. Judges agreed that the characteristics distinguishing girls' from boys' drawings were use of details, neatness, colorfulness, smiling face, and symmetry; while boys' drawings differed from girls' in their frightening faces, messiness, incompleteness, and unconventionality. Judges were accurate about 60% of the time in identifying boys but only about 30% of the time in identifying girls, a statistically reliable difference.The cooperation of the kindergarten children in South Road (SR) and West Kingston (WK) schools, their teachers, Frances Streeter and Susan Wise, and their principals, John Fratiello and Richard Corcoran, is gratefully acknowledged. Thanks are also extended to the university students whose participation contributed to this investigation.  相似文献

The aim of this study was to examine developmental differences in autobiographical memory using a novel test that assesses its semantic and episodic subcomponents. Forty-two children aged 7-13 years were asked to recall semantic information and episodic events from three different time periods (current school year, last school year, and previous school years). For the recalls of all events, sense of remembering or sense of just knowing was measured via the Remember/Know paradigm. Age-related differences were observed for episodic autobiographical memory whereas semantic autobiographical memory was characterized by a relative developmental invariance. The increase with age was also found in the number of "Remember" responses and their justification in terms of the actual contextual information retrieved-factual, spatial, and, more especially, temporal details. These findings highlight developmental differences between the episodic and semantic subcomponents of autobiographical memory and support the view that mental 'time travel' through subjective time, which allows one to re-experience the past through self-awareness, is the last feature of autobiographical memory to become fully operational.  相似文献

The answers to the questions in the title depend on the kind of pluralism one is talking about. We will focus here on our own views. The purpose of this article is to trace out some possible connections between these kinds of pluralism. We show how each of them might bear on the other, depending on how certain open questions are resolved.

White matter occupies almost half of the human brain. It contains axons connecting spatially segregated modules and, as such, it is essential for the smooth flow of information in functional networks. Structural maturation of white matter continues during adolescence, as reflected in age-related changes in its volume, as well as in its microstructure. Here I review recent observations obtained with magnetic resonance imaging in typically developing adolescents and point out some of the known variations in structural properties of white matter vis-à-vis brain function in health and disease. I conclude by re-focusing the interpretations of MR-based studies of white matter from myelin to axon.  相似文献

The modality effect is a central issue in multimedia learning [see Mayer (Cambridge University Press, 2005a), for a review]. Sweller’s Cognitive Load Theory (CLT), for example, presumes that an illustrated text is better understood when presented visually rather than orally. The predictive power of CLT lies in how it links in to Baddeley’s (1986) model of working memory and Penney’s (Mem Cognit 17:398–442, 1989) Separate-Streams Hypothesis. Ginns’s (Learn Instr 4:313–331, 2005) recent meta-analysis also supports the modality effect (d = 0.72, based on 43 independent effects). This article replicates the meta-analysis of the modality effect based on 86 independent effects (with within-study subgroups as the unit of analysis and with mean of the outcomes as the dependent measure), with results showing a reduction of the overall effect size by almost half (d = 0.38), and even more when Duval and Tweedie’s Trim and Fill method is used to correct publication bias (d = 0.20). This article also widens the scope of the analysis of moderator variables (e.g. Pace of presentation, Type of visualization, Research group) as well as their potentially confounded effects. Finally, it is argued that, for theoretical reasons, the so-called modality effect cannot be based on Penney’s or Baddeley’s theories and must be explained in a different way.  相似文献

How do perceivers combine information about perceptually obvious categories (e.g., Black) with information about perceptually ambiguous categories (e.g., gay) during impression formation? Given that gay stereotypes are activated automatically, we predicted that positive gay stereotypes confer evaluative benefits to Black gay targets, even when perceivers are unaware of targets' sexual orientations. Participants in Study 1 rated faces of White straight men as more likable than White gay men, but rated Black men in the opposite manner: gays were liked more than straights. In Study 2, participants approaching Whites during an approach–avoidance task responded faster to straights than gays, whereas participants approaching Blacks responded faster to gays than straights. These findings highlight the striking extent to which less visible categories, like sexual orientation, subtly influence person perception and determine the explicit and implicit evaluations individuals form about others.  相似文献

The influence of video game realism and controller naturalness on aggression was examined with an experiment that manipulated game realism and controller naturalness. Perceived controller naturalness increased perceptions of realism of the game and led to greater immersion. The more realistic game was perceived as such and led to greater immersion. Ultimately, greater immersion led to more cognitive aggression. Results are discussed in terms of a mental models approach and the process of model matching.  相似文献

HomeNetToo is a longitudinal field study designed to examine the antecedents and consequences of home Internet use in low-income families (http://www.HomeNetToo.org). The study was done between December 2000 and June 2002. Among the consequences considered was children's academic performance. Participants were 140 children, mostly African American (83%), mostly boys (58%), and most living in single-parent households (75%) in which the median annual income was 15,000 (U.S. dollars) or less. Average age was 13.8 years. Ages ranged between 10 and 18 years, Internet use was continuously recorded, and multiple measures of academic performance were obtained during the 16-month trial. Findings indicated that children who used the Internet more had higher scores on standardized tests of reading achievement and higher grade point averages 6 months, 1 year, and 16 months later than did children who used it less. Older children used the Internet more than did younger children, but age had no effect on the nature or the academic performance benefits of Internet use. Implications for the digital "use" divide are discussed.  相似文献

This experiment investigated challenge evaluations in soccer and their relation to prejudice: more precisely, whether skin colour may influence judgments of soccer tackles. Three groups of participants (soccer players, referees,and soccer fans) were asked to evaluate challenges, featuring Black and White players as aggressors and victims in a mixed-design study. Results showed that participants made some differentiations between Black and White players in a challenge evaluation task. Participants were more likely to consider within-group challenges as fouls and were faster to consider challenges made by Black players as fouls. On the other hand, fouls made by White players were seen as more severe. There were no major differences between the participating groups, suggesting that the observed effects were independent of how good players were or whether the participants were referees or not.  相似文献

Racial asymmetry, the circumstance of having a teacher’s race differ from that of his or her student’s race, is often considered important because most Black students are taught by White teachers. This paper analyzes data from a nationally representative sample of students and teachers to ascertain the extent to which Black and White teachers differ in their evaluations of the work habits of their Black pupils. Unlike most other investigations on this topic, we explored the likelihood that subject matter and school demographics influence teacher-student relationships beyond the more visible factors of racial symmetry or asymmetry. Our analyses of NELS: 88 data using this framework reveal an inconsistent racial effect on teachers’ evaluations of Black students. The ratings of African American pupils by both Black and White teachers seem to be influenced by both the academic subject they teach and the demographic characteristic of the school. We discuss these findings and suggest avenues for further study.

Is the process of helping infants and young children learn to sleep through the night a solution to family sleep problems or does it exacerbate matters for mother and child? Retrospective and current accounts from a nonclinical, convenience sample of 102 mothers of preschool‐aged children provided information on sleep issues from early infancy through preschool age. Child, mother, and parenting characteristics, along with family sleep arrangements, were differentially related to the age at which children learned to sleep through the night and to the extent of difficulty that characterized this experience. Mothers who indicated more difficulty as their children learned to sleep through the night also reported more depressive symptoms and more strain in the mother–child relationship. Later age at sleeping through the night was more common among early bedsharers, but timing of sleeping through the night was not associated with preschool children's reported independence in several nonsleep domains. Sleep arrangements and the importance placed on sleeping through the night were the strongest contributors to variance explained in whether children learned to sleep through the night during infancy or toddlerhood. When advising parents about sleep interventions, practitioners should seek to understand whether families' parenting values fit their nighttime sleep practices.  相似文献

The aims of this study are: (1) to describe language and temperament characteristics of one group of low risk preterm (PR) children and a group of full-term (FT) children and (2) to identify those factors which can predict language outcomes at 30 months of age, with special attention on temperament. There is evidence of differences between very or extremely PR and FT children in relation to characteristics of temperament and language development. However, not many studies have been carried out with healthy PR children.The participants were 142 low risk PR children (mean gestational age (GA): 32.60 weeks) and 49 FT children (mean GA 39.84 weeks). The temperament of the children was assessed at 10 months of age through the Infant Behavior Questionnaire-Revised (IBQ-R). At 22 months of age the cognitive development of the children was assessed through the Spanish adaptation of the Batelle Developmental Inventory (BDI). In order to assess the children's language development the Galician adaptation of the MacArthur–Bates CDI was applied at 30 months of age. In addition, socio-demographic information about the children and their families was gathered at birth.The results indicate that there were no significant differences in the language measures of interest (word production, MLU3, and sentence complexity) between groups. The only differences found between the PR and the FT children in the IBQ-R were restricted to the smiling and laughter and the fear subscales. Hierarchical regression analyses performed indicate that GA did not have any predictive effect on language measures taken at 30 months. Cognitive scores were an important predictor of language measures, although certain temperament subscales contributed in a significant way to the variance of language measures, particularly low intensity pleasure, approach, high intensity pleasure, sadness, and vocal reactivity. Therefore, extroverted (positive affectivity) temperament seems to be beneficial for language development.  相似文献

Club good models developed by economists suggest that the club provides a benefit to members by fostering the provision of semi-public goods. In the case of religion, churches create enforcement mechanisms to reduce free riding. Consequently, the psychic costs of deviant activity should be higher for individuals who belong to religious groups with strong social norms. Data from the General Social Survey are used to examine whether the cost of using pornography is greater for the more religiously involved. We measure the cost of using pornography as the happiness gap or the gap between the average happiness reported by individuals who do and individuals who do not report using pornography. The happiness gap is larger for individuals who regularly attend church and who belong to religious groups with strong attitudes against pornography.  相似文献
