Reducing the sex difference in math anxiety: The role of spatial processing ability

Decades of research have demonstrated that women experience higher rates of math anxiety – that is, negative affect when performing tasks involving numerical and mathematical skill – than men. Researchers have largely attributed this sex difference in math anxiety to factors such as social stereotypes and propensity to report anxiety. Here we provide the first evidence that the sex difference in math anxiety may be due in part to sex differences in spatial processing ability. In Study 1, undergraduate students completed questionnaires assessing their level of math anxiety and their aptitude and preference for processing spatial configurations and schematic images. The results support the hypothesis that the relation between sex and math anxiety is mediated by spatial processing ability. In Study 2, we replicate these results with a more diverse sample of adults. Implications for the prevention and remediation of math anxiety and math anxiety-related achievement deficits are discussed.     

Emergence and characterization of sex differences in spatial ability: a meta-analysis

Sex differences in spatial ability are widely acknowledged, yet considerable dispute surrounds the magnitude, nature, and age of first occurrence of these differences. This article focuses on 3 questions about sex differences in spatial ability: What is the magnitude of sex differences in spatial ability? On which aspects of spatial ability are sex differences found? and When, in the life span, are sex differences in spatial ability first detected? Implications for clarifying the linkage between sex differences in spatial ability and other differences between males and females are discussed. We use meta-analysis, a method for synthesizing empirical studies, to investigate these questions. Results of the meta-analysis suggest that sex differences arise on some types of spatial ability but not others, that large sex differences are found only on measures of mental rotation, that smaller sex differences are found on measures of spatial perception, and that, when sex differences are found, they can be detected across the life span.     

Individual differences in spatial text processing: High spatial ability can compensate for spatial working memory interference

The present study investigates the relation between spatial ability and visuo-spatial and verbal working memory in spatial text processing. In two experiments, participants listened to a spatial text (Experiments 1 and 2) and a non-spatial text (Experiment 1), at the same time performing a spatial or a verbal concurrent task, or no secondary task. To understand how individuals who differ in spatial ability process spatial text during dual task performance, spatial individual differences were analyzed. The tasks administered were the Vandenberg and Kuse [Vandenberg, S. G., & Kuse, A. R. (1978). Mental rotation, a group test of three-dimensional spatial visualization. Perceptual and Motor Skills, 47, 599-604.] mental rotation test (MRT) and a reading comprehension task (RCT). Individuals with high (HMR) and low (LMR) mental rotation differed in MRT scores but had similar RCT performance. Results showed that the HMR group, in contrast with LMR counterparts, preserved good spatial text recall even when a spatial concurrent task was performed; however, Experiment 2 revealed a modification of spatial concurrent task performance in LMR as well in HMR group. Overall, results suggest that HMR individuals have more spatial resources than LMR individuals, allowing them to compensate for spatial working memory interference, but only to a limited extent, given that the processing of spatial information is still mediated by VSWM.     

Developmental patterns in security of attachment to mother and father in late childhood and early adolescence: associations with peer relations

This study examined developmental differences in two dimensions of attachment security (parental availability and child dependency on parents) in late childhood (N = 274) and early adolescence (N = 267) and their association with peer relations. Children's perceptions of mother's availability and boys' perceptions of father's availability did not differ as a function of age. Dependency on parents, however, decreased with age. Findings highlight the importance of distinguishing between parental availability and reliance on parental help when measuring attachment developmentally. Children's reports of positive friendship qualities and lack of conflict in their best friendships were related to attachment to both mother and father, whereas the presence of a reciprocated friendship and popularity were not. Father availability was a particularly important predictor of lower conflict with best friends. Findings indicate that the quality of parent-child attachment generalizes primarily to the quality of children's close peer relations.     

Developmental patterns of privatization in higher education: a comparative study

In most developing countries, as the young population increase in number and consequently, the demands for higher education rise, the governments cannot respond to all demands. Accordingly, they develop private higher education sectors as an alternative solution. In developed countries, some moving factors are influential in creation and the increase of private institutions but there are scarce evidences and comparative results about developing countries. The current comparative study seeks to investigate and analyze the main factors of privatization in higher education of three developing countries: Indonesia, Malaysia, and Kenya. After a short outline of theoretical foundations, this study provides more in-depth explanations of the principal and common effective factors.     

Rethinking difference and sex education: from cultural inclusivity to normative diversity

This paper aimed to problematise what is meant by ‘difference’ and consider what such a reinterpretation might mean for methodological interventions in sex education research. Our concern is the tendency for sex education research to treat difference as a set of categories to be ‘added-on’, such as religious difference, cultural difference and sexual plurality. The danger of this is that it leaves the normative unchallenged, confirming the hegemony of the heteronormative, unraced subject. Constructing difference as an ‘add-on’ fails to address how young people locate themselves in a world in which they negotiate their sexualities through complex ‘glocal’ routes in popular and youth culture. We argue that decentring methodological strategies are required which draw on critiques made by post-colonial and decolonising methodologies. In the first section of the paper, we review the problem of difference, and how it is considered within current debates in youth and sexualities research. This frames a reflection on rethinking our own methodological practices through a consideration of two research moments. In the conclusion, we propose a metaphorical framework to scaffold a reimagining of methodological approaches to ensure that the normative is always a question mark.     

Developmental trends for object and spatial working memory: a psychophysiological analysis

This study examined developmental trends in object and spatial working memory (WM) using heart rate (HR) to provide an index of covert cognitive processes. Participants in 4 age groups (6-7, 9-10, 11-12, 18-26, n=20 each) performed object and spatial WM tasks, in which each trial was followed by feedback. Spatial WM task performance reached adult levels before object WM task performance. The differential developmental trends for object and spatial WM found in this study are taken to suggest that these WM components are separable. Negative performance feedback elicited HR slowing that was more pronounced for adults than for children. The development of performance monitoring as indexed by covert HR slowing following performance feedback contributes to WM performance.

Gender differences in spatial ability: Relationship to spatial experience among Chinese gifted students in Hong Kong

Spatial ability based on measures of mental rotation, and spatial experience based on self‐reported participation in visual‐arts as well as spatial‐orientation activities were assessed in a sample of 337 Chinese, gifted students. Consistent with past findings for the general population, there were gender differences in spatial ability favoring boys. However, other results provided little support for the idea that gender differences in spatial experience might foster gender differences in spatial ability; specifically, results showed modest gender differences in visual‐arts experience favoring girls, and variation in visual orientation experience favoring secondary‐school boys. Nonetheless, the role of spatial experience had a more marked effect on girls, suggesting that encouraging female students to gain spatial experience might help bridge the gap in spatial ability between the genders.     

Correlates of ability patterns in children and adults: Implications for teaching

Several researches are presented as evidence that children with a high verbal -low spatial ability profile fend to respond in the “usual” way to social reinforcement or praise, whereas children with a high spatial - low verbal profile do not find such praise reinforcing. Several implications for teaching such HiS-LoS and HiV-LoS children are seen in these studies and considered in detail. Specifically the following implications are discussed: (a) the need for better identification of children with HiV-LoS and HiS-LoV profiles, (b) what kinds of reinforcers to use with these children in the classroom, (c) group vs. individual instruction, (d) the need to socialize the HiS-LoV child, and (e) the need for care in academic assessment.     

The impact of early institutional rearing on the ability to discriminate facial expressions of emotion: an event-related potential study

Event-related potentials (ERPs), in response to 4 facial expressions of fear, angry, happy, and sad, were collected from 72 institutionalized children (IG), ages 7 to 32 months, in Bucharest, Romania, and compared with ERPs from 33 children, ages 8 to 32 months, who had never been institutionalized (NIG). The NIG and IG exhibited different patterns of responding in early latency components. Moreover, group differences in amplitude were evident across all components. Such differences may point to the role of early deprivation in disrupting the development of the neural circuitry involved in the recognition of facial expressions.     

The role of dynamic spatial ability in geoscience text comprehension

The current experiment investigated the effects of a dynamic spatial ability on comprehension of a geoscience text on plate tectonics and the causes of volcanic activity. 162 undergraduates (54% female) from a large public university who had little prior knowledge of this science content area were asked to learn about plate tectonics. Measures of spatial ability and working memory capacity were used to predict comprehension from a text that contained either no images, static images, or animated versions of the static images. Only the dynamic spatial ability measure interacted with the type of illustrations contained in the text, and was shown to be especially relevant for comprehension when readers did not receive animations. These results demonstrate a novel influence of individual differences in dynamic spatial ability on comprehension of text describing dynamic spatial phenomena.     

Developmental trajectories of children's spatial skills: Influencing variables and associations with later mathematical thinking

Few studies have examined the long-term relations between children's early spatial skills and their later mathematical abilities. In the current study, we investigated children's developmental trajectories of spatial skills across four waves from age 3–7 years and their association with children's later mathematical understanding. We assessed children's development in a large, heterogeneous sample of children (N = 586) from diverse cultural backgrounds and mostly low-income homes. Spatial and mathematical skills were measured using standardized assessments. Children's starting points and rate of growth in spatial skills were investigated using latent growth curve models. We explored the influence of various covariates on spatial skill development and found that socioeconomic status, language skills, and sex, but not migration background predicted children's spatial development. Furthermore, our findings showed that children's initial spatial skills––but not their rate of growth––predicted later mathematical understanding, indicating that early spatial reasoning may play a crucial role for learning mathematics.     

Asymmetric action in the human newborn: sex differences in patterns of organization.

We developed a procedure and scale to quantify movement asymmetry in 36 full-term newborns from several normal newborn nurseries (Measure of Behavioral Laterality, MOBL). The majority of newborns had elicited reflexes and spontaneous movements that were stronger and more coordinated on the right than on the left side of the body; there was no asymmetry in the latency, threshold, or habituation of these behaviors. Although asymmetry of different movements was associated if they relied on the same motor pool, there was little association of movement asymmetries among different body regions, indicating that multiple subsystems, rather than a single asymmetric system, controls asymmetric action in the newborn. Finally, there was a sex difference in asymmetry of all 3 distal lower-body elicited reflexes: females were right biased, but the majority of males were left biased. These sex differences are discussed in terms of alternative mechanisms for the development of asymmetric action and the role of newborn reflexes in adult voluntary movement.
