Multiple Representations in Number Line Estimation: A Developmental Shift or Classes of Representations?

Children's estimation patterns on a number line estimation task may provide information about the mental representation of the magnitude of numbers. Siegler and his colleagues concluded that children's mental representations shift from a logarithmic-ruler representation to a linear-ruler representation. However, there are important methodological issues with respect to their number-line studies that threaten the validity of the conclusions. We discuss these methodological issues and propose an alternative method to analyze estimation data. One hundred nineteen children from kindergarten, first, and second grade performed a number-line estimation task in which they had to estimate the position of 30 numbers on a 0-to-100 number line. The results supported the hypothesis that children show various kinds of estimation patterns. Five classes of children were distinguished, which were characterized by different estimation patterns. A remarkable result was that the logarithmic-ruler representation was not found. Although young children were more likely to show overestimation of small numbers than older children, this developmental trend was small and not significant.     

Sexual orientation and shifts in preferences for a partner's body attributes in short-term versus long-term mating contexts

This study assessed the effects of short- and long-term mating contexts on preferences for body characteristics of potential relationship partners in lesbians and heterosexual women. Lesbians (n = 41) rated figure drawings and computer-generated images of women that varied in body fat, waist-to-hip ratio, and breast size; heterosexual women (n = 95) rated computer-generated images of men that varied in muscularity and body fat. Both lesbians and heterosexual women showed a shift in preferences toward more physically attractive partners for shortterm relationships. All body aspects were affected, except that heterosexual women did not show a preference shift for male body fat. The results were interpreted in terms of a mating trade-off strategy in which mate preferences are the consequence of cost/benefit analyses and suggest that preferences for physical attributes of sexual partners may be shared by members of the same sex regardless of sexual orientation.     

Perceived past, present, and future control and adjustment to stressful life events

Perceived control is a central construct in psychology and is key to understanding individual differences in poststress outcomes (Frazier, Berman, & Steward, 2001). The goals of the current studies (using 4 samples of undergraduate students, total N = 1,421) were to examine the relations between different aspects of perceived control and poststress outcomes and to differentiate perceived control over specific events from related constructs (i.e., general control beliefs, coping strategies). To accomplish these goals, we first developed a new measure of perceived past, present, and future control over stressful life events. The data supported the content validity, factor structure, internal consistency and test-retest reliability, and convergent and discriminant validity of the new measure. Consistent with the temporal model of control (Frazier et al., 2001), these 3 forms of control had very different relations with adjustment. Present control was consistently related to lower distress levels in cross-sectional, longitudinal, and prospective analyses. Present control also predicted outcomes beyond the effects of general control beliefs and coping strategies. Past and future control had nonsignificant or positive relations with distress, although future control was associated with better outcomes (i.e., course grades) when the stressor was controllable. Thus, our measure can be used to assess the relations between perceived past, present, and future control and outcomes across a range of stressors. Because the relations between these 3 forms of control and outcomes differ markedly, measures that combine these aspects of control hinder the understanding of the important role of perceived control in adjustment to stress.     

Depressive implicit associations and adults' reports of childhood abuse

Theory and research suggest that negative events in childhood (e.g., childhood abuse) may contribute to the development of a cognitive vulnerability to depression. A limitation of past research, however, is that the majority has focused on explicit cognitions (e.g., attributional style) and it remains unclear whether similar relations would be observed for more implicit measures of depressive cognitions. This study investigated the relation between young adults' reports of childhood abuse and their implicit depressive cognitions, as measured by the Implicit Association Test. As hypothesised, young adults reporting a history of childhood abuse exhibited stronger implicit associations for depression-relevant stimuli than did individuals with no abuse history. These results were maintained even after statistically controlling for the influence of current depressive symptom levels.     

Orthography influences the perception and production of speech

One intriguing question in language research concerns the extent to which orthographic information impacts on spoken word processing. Previous research has faced a number of methodological difficulties and has not reached a definitive conclusion. Our research addresses these difficulties by capitalizing on recent developments in the area of word learning. Participants were trained to criterion on a set of associations between novel pictures and novel spoken words. Spelling-sound consistent or spelling-sound inconsistent spellings were introduced on the 2nd day, and the influence of these spellings on speech processing was assessed on the 3rd day. Results showed significant orthographic effects on speech perception and speech production in a situation in which spelling-sound consistency was manipulated with perfect experimental control. Results are discussed in terms of a highly interactive language system in which there is a rapid and automatic flow of activation in both directions between orthographic and phonological representations.     

The Role of Repetitive Negative Thoughts in the Vulnerability for Emotional Problems in Non-Clinical Children

The current study examined the role of repetitive negative thoughts in the vulnerability for emotional problems in non-clinical children aged 8–13 years (N = 158). Children completed self-report questionnaires for assessing (1) neuroticism and behavioral inhibition as indicators of general vulnerability (2) worry and rumination which are two important manifestations of repetitive negative thoughts, and (3) emotional problems (i.e., anxiety, depression, and sleep difficulties). Results demonstrated that there were positive correlations between measures of general vulnerability, repetitive negative thoughts, and emotional problems. Further, support was found for a model in which worry and rumination acted as partial mediators in the relation between neuroticism and symptoms of anxiety and depression. In the case of sleep difficulties, no evidence was obtained for such a mediation model. In fact, data suggested that sleeping difficulties are better conceived as an epiphenomenon of high symptom levels of anxiety and depression or as a risk factor for the development of other types of psychopathology. Finally, besides neuroticism, the temperamental trait of behavioral inhibition appeared to play a unique direct role in the model predicting anxiety symptoms but not in the models predicting depressive symptoms or sleep difficulties. To conclude, the current findings seem to indicate that worry and rumination contribute to children’s vulnerability for anxiety and depression.     

??Putting on?? Sexiness: A Content Analysis of the Presence of Sexualizing Characteristics in Girls?? Clothing

Objectification theory (Fredrickson and Roberts 1997) proposes that women from Western cultures are widely portrayed and treated as objects of the male gaze, leading to the development of self-objectification, in which girls and women internalize these societal messages and view their own bodies as objects to be evaluated according to narrow standards of (often sexualized) attractiveness. Prompted by findings from the American Psychological Association Task Force on the Sexualization of Girls (APA 2007), the present study considers girls?? clothing as a possible socializing influence that may contribute to the development of self-objectification in preteen girls. Accordingly, in this content analysis, we examined the frequency and nature of ??sexualizing?? clothing available for girl children (generally sizes 6?C14) on the websites of 15 popular stores in the US. Sexualizing clothing was defined as clothing that revealed or emphasized a sexualized body part, had characteristics associated with sexiness, and/or had sexually suggestive writing. Clothing was also coded for childlike characteristics, such as child-like fabric (e.g., polka dot pattern) or a modest, non-revealing cut. Across all stores and all articles of clothing, 69% of the clothing items were coded as having only childlike characteristics, 4% as having only sexualizing characteristics, 25.4% as having both sexualizing and childlike characteristics, and 1% as having neither sexualizing nor childlike characteristics. ??Tween?? stores like Abercrombie Kids had the highest proportion of sexualizing clothing. The findings are discussed within the framework of the development of self-objectification.     

Feeling good: autonomic nervous system responding in five positive emotions

Although dozens of studies have examined the autonomic nervous system (ANS) aspects of negative emotions, less is known about ANS responding in positive emotion. An evolutionary framework was used to define five positive emotions in terms of fitness-enhancing function, and to guide hypotheses regarding autonomic responding. In a repeated measures design, participants viewed sets of visual images eliciting these positive emotions (anticipatory enthusiasm, attachment love, nurturant love, amusement, and awe) plus an emotionally neutral state. Peripheral measures of sympathetic and vagal parasympathetic activation were assessed. Results indicated that the emotion conditions were characterized by qualitatively distinct profiles of autonomic activation, suggesting the existence of multiple, physiologically distinct positive emotions.     

T1 difficulty affects the AB: manipulating T1 word frequency and T1 orthographic neighbor frequency

Colored target words were presented with distractor nonwords in a rapid serial visual presentation (RSVP) task. In Experiment 1, the attentional blink (AB) effect on T2 accuracy was larger when T1 was a difficult (low-frequency) word than when it was a high-frequency word. In Experiment 2 the effect of T1 frequency on the AB was replicated in a between-participants design, and the frequency of T1’s one-letter different neighbors (e.g., case, bare, for care) interacted with T1 frequency in its effects on T2 accuracy. Experiment 3 confirmed the effect of T1 frequency over 6 T1-T2 lags. The effects of T1 characteristics were sensitively assessed in the AB and were more consistent with resource depletion theories than control-process accounts.
