This article proposes an integrated theory of acquisition of knowledge about whole numbers and fractions. Although whole numbers and fractions differ in many ways that influence their development, an important commonality is the centrality of knowledge of numerical magnitudes in overall understanding. The present findings with 11- and 13-year-olds indicate that, as with whole numbers, accuracy of fraction magnitude representations is closely related to both fractions arithmetic proficiency and overall mathematics achievement test scores, that fraction magnitude representations account for substantial variance in mathematics achievement test scores beyond that explained by fraction arithmetic proficiency, and that developing effective strategies plays a key role in improved knowledge of fractions. Theoretical and instructional implications are discussed. 相似文献

The aim of the present study was to assess the predictive power of the processing of pain-related information, comprising concepts of hypervigilance to pain, pain catastrophizing, and pain-related anxiety (questionnaires) as well as attentional processes related to pain-related stimuli (dot-probe task) in explaining individual differences in experimental pain sensitivity (pressure/thermal pain threshold). In 160 healthy participants (ages 13-61; 80 females), results of hierarchical multiple regression analyses showed that self-reported hypervigilance contributed significantly to the prediction of pain sensitivity, whereas pain catastrophizing and anxiety did not. However, inconsistent with prediction, the effect was in the opposite direction, indicating that vigilance to pain sensations or stimuli is associated with lower pain sensitivity in healthy individuals. Entering the attentional bias indices from the dot-probe task showed that an increased bias to pain words is related to higher experimental pain sensitivity, which confirms the hypothesis. 相似文献

The lack of available Spanish versions of assessment measures contributes to insufficient research and underutilization of
mental health services for Latino children with Attention-Deficit/Hyperactivity Disorder (ADHD). Thus, the goal of the current
study was to examine the psychometric and cultural properties of several Spanish versions of parental/family functioning measures
commonly used in comprehensive ADHD assessments (i.e., the Parenting Sense of Competence Scale, Alabama Parenting Questionnaire,
and Confusion, Hubbub, and Order Scale). Participants included 68 Spanish-speaking, Latino parents in Southeast Wisconsin.
In general, the Spanish translations of the measures demonstrated good reliability and validity. Furthermore, the psychometrically-sound
measures were significantly related to acculturation as predicted, suggesting that the scales are not only psychometrically
valid, but also culturally valid for use with Spanish-speaking, Latino families. 相似文献

Do voters have the same stereotypes of Black politicians that they have of Black people in general? We argue that common stereotypes of Blacks (e.g., lazy, violent) may not apply to perceptions of Black politicians. Instead, we hypothesize that Black politicians are a unique subtype of the larger group Blacks, different enough to warrant their own stereotypes. We take an inductive approach to understanding the stereotypes of Black politicians. Employing a classic psychology research design ( Katz & Braly, 1933 ) in which respondents list traits for a target group, we find that there is little overlap of stereotype content between Black politicians and Blacks. Our results therefore indicate that Black politicians constitute a separate and unique subtype of Blacks. Our analysis explores similarities and differences between stereotypes of Black politicians and two other groups: Black professionals (another subtype of Blacks) and politicians. We discuss the implications of our findings for the relationship between stereotypes and voter decisions. 相似文献

Objective
Variability in infant sleep and negative affective behavior (NAB) is a developmental phenomenon that has long been of interest to researchers and clinicians. However, analyses and delineation of such temporal patterns were often limited to basic statistical approaches, which may prevent adequate identification of meaningful variation within these patterns. Modern statistical procedures such as additive models may detect specific patterns of temporal variation in infant behavior more effectively.Method
Hundred and twenty-one mothers were asked to record different behaviors of their 4–44 weeks old healthy infants by diaries for three days consecutively. Circadian patterns as well as individual trajectories and day-to-day variability of infant sleep and NAB were modeled with generalized linear models (GLMs) including a linear and quadratic polynomial for time, a GLM with a polynomial of the 8th order, a GLM with a harmonic function, a generalized linear mixed model (GLMM) with a polynomial of the 8th order, a generalized additive model, and a generalized additive mixed model (GAMM).Results
The semi-parametric model GAMM was found to fit the data of infant sleep better than any other parametric model used. GLMM with a polynomial of the 8th order and GAMM modeled temporal patterns of infant NAB equally well, although the GLMM exhibited a slightly better model fit while GAMM was easier to interpret. Besides the well-known evening clustering in infant NAB we found a significant second peak in NAB around midday that was not affected by the constant decline in the amounts of NAB across the 3-day study period.Conclusion
Using advanced statistical procedures (GAMM and GLMM) even small variations and phenomena in infant behavior can be reliably detected. Future studies investigating variability and temporal patterns in infant variables may benefit from these statistical approaches. 相似文献266.

Background
The development of appropriate preventive measures aimed at the promotion of psychosocial capabilities and health behavior is based on the recognition that unemployment is associated with many physical, psychological and social problems.Objective
A group program ??promotion of health and psychosocial self-efficacy in long-term unemployed?? was developed and investigated with respect to the effectiveness by a study group at the Clinic for Psychosomatic Medicine of the University of Rostock. The study was part of a project funded by the European Social Fund (ESF).Methods
During the period from October 2009 to April 2010 the group program was implemented in 5 different groups and the sample included a total of 35 persons. To examine the effectiveness of the program the participants had to complete standardized questionnaires at the beginning and at the end of the program. Information as to what extent the unemployed suffer from mental stress was collected via the brief symptom inventory (BSI; Franke 2000). The questionnaire on resources and self-management skills (FERUS; Jack 2007) was applied to analyze the capabilities and the self-management skills of the participants.Results
The unemployed subjects reported lower levels of aggressiveness and paranoid thinking (distrust) after their participation in the program. Regarding the self-management skills the participants improved their coping skills, self-instructions skills and also felt more hopeful with regard to their current environment and the future.Conclusions
A systematic support of unemployed people regarding coping with the psychosocial problems associated with unemployment seemed to be important. The use of low structured group programs is a good possibility to implement them in different contexts with relatively few resources. 相似文献268.
People use spatial distance to talk and think about differences between concepts, and it has been argued that using space to think about different categories provides a scaffold for the categorization process. In the current study, we investigated the possibility that the distance between response keys can influence categorization times in binary classification tasks. In line with the hypothesis that distance between response keys can facilitate response selection in a key-press version of the Stroop task, our results showed that responses on incongruent Stroop trials were significantly facilitated when participants performed the Stroop task with response keys located far apart, compared with when they performed the task with response keys located close together. These results support the idea that the spatial structuring of response options facilitates categorizations that require cognitive effort, and that people can incorporate environmental structures such as spatial distance in their thought processes. Keeping your hands apart might actually help to keep things apart in your mind. 相似文献

A new suicide-specific diagnostic entity, acute suicidal affective disturbance (ASAD), was recently proposed to fill a void in the nomenclature. Although several studies have examined the reliability, validity, and potential clinical utility of ASAD, no studies have examined personality indicators of ASAD. This study sought to examine the association between personality and psychopathology factors, as assessed by the Minnesota Multiphasic Personality Inventory–2–Revised Form (MMPI–2–RF), and constructs that comprise ASAD in a sample of 554 psychiatric outpatients who completed all measures prior to their intake appointments. A smaller subset of patients (N = 58) also completed a measure designed to assess lifetime ASAD symptoms. Results indicated that ASAD symptoms were associated with traits characterized by emotional turmoil and atypical cognitive processes. Further, suicide-related criteria that comprise ASAD were related to low positive emotionality and hopelessness, whereas the overarousal criteria were associated with somatic symptoms and an inability to tolerate frustration and stress. These findings expand on previous research that examines the convergent and discriminant validity of ASAD and could inform clinical treatment by providing insight into personality traits that might be associated with acute suicide risk. 相似文献

Intuitions play a central role in everyday life decision-making but little is known regarding this capacity during depression. Thus, in Study 1, N?=?39 depressed in-patients completed two well-established tasks, assessing intuitions of visual and semantic coherence. In the semantic coherence task, patients judged whether presented words triads were coherent (e.g. SALT DEEP FOAM, related to SEA) or not (e.g. DREAM BALL BOOK, no denominator). In the visual coherence task, patients judged whether blurred pictures depicted real-life objects (coherent) or not (incoherent). Results showed that higher depressive symptomatology was associated with impaired intuitions of semantic coherence but with enhanced intuitions of visual coherence. In Study 2, visual coherence intuitions of depressed patients (n?=?27) were compared to healthy control participants (n?=?30). Depressed patients outperformed the healthy control subjects in the visual coherence task. This pattern of findings shows both detrimental and beneficial decisional consequences of depression. 相似文献
