Cognitive and behavioral attention in children with math difficulties

Cognitive assessments and behavioral ratings of attention were used to examine the relation of inattention to math performance in children. Third grade students with math difficulties (MD; n?=?17) and math and reading difficulties (MDRD; n?=?35) were administered the Attentional Network Test (ANT), as well as achievement and intelligence measures. Strengths and Weaknesses of ADHD-Symptoms and Normal-Behavior-IV (SWAN-IV) Inattention ratings were collected from teachers. Two comparison groups were also recruited: a typically achieving group (n?=?23) and a group that responded to a math-tutoring intervention (responders; n?=?54). On the ANT, children with MD and MDRD did not perform significantly different than typically achieving children or responders on measures of alerting and orienting attention and executive control. All subgroups did demonstrate performance patterns that were expected on the ANT. However, performance across blocks of the task was inconsistent, suggesting poor reliability. There were no relations between ANT performance and SWAN-IV behavioral inattention scores, though behavioral ratings of inattention correlated significantly with math performance. Children with MD and MDRD may have more difficulty with distraction and attention to detail in contextual situations, as opposed to impulsive responding in these settings. The lack of relation between cognitive attention and math performance may suggest that either the ANT does not assess the relevant attention constructs associated with math difficulties or may parallel studies of attention deficit/hyperactivity disorder (ADHD) in which cognitive and behavioral assessments are weakly related.     

Evaluation of a Parental Behavior Scale in a Peruvian Context

The purpose of this study was to investigate psychometric properties (factorial structure, reliability, and criterion validity) of a Spanish version of the Parental Behavior Scale (PBS), an instrument developed to assess observable parental behavior. The sample consisted of 591 Peruvian families in Metropolitan Lima. Parents, mostly mothers, completed the scale regarding one target child attending 6th grade of primary education. Two models were tested using confirmatory factor analysis: a nine-factor model based on the original PBS and a five-factor model (PBS short version). Both models fitted the data well. A multi-sample confirmatory factor analysis showed that the factor structure, factor loadings and correlations were invariant for groups of parents with children in public or in private schools. Four factors showed adequate reliability: Positive Parenting, Rules, Discipline and Harsh Punishment. Correlational analyses showed significant associations between harsh punishment and child behavioral problems, measured with the Strengths and Difficulties Questionnaire, and with the family environment, measured with the Home Observation for Measurement of the Environment.     

Governmentality in Service Provision for Migrated Women in Spain

A gender perspective has been incorporated in transnational migration studies over the last two decades in Spain. According to feminist inquiry, research has focused mainly on four areas: transnational maternities, transformation in global care regimes, multiple discrimination experiences and change in gender relations by means of migration. In this paper, we suggest that there is a fifth area that has been neglected: one that studies the ways in which governmentality practices, performed within service provision aimed at migrant populations, are enacted in host societies. We argue that mechanisms of categorisation developed in service provision in Spain contribute to the construction of the category of “Third World Women”. A set of discourses and practices that are based on gender and cultural assignation related with stereotyped understandings of migrated women in host societies, situating them as suitable workers for current care regimes within these societies. These mechanisms have an important impact on life situations experienced by many migrated women as they are integrated into a low waged and undervalued work market. Further developments must be made in this last area of inquiry from a critical standpoint, in order to avoid the reproduction of discriminatory practices within institutional intervention settings.     

GENDER AND WORK HISTORY IN THE PLACEMENT AND PERCEPTIONS OF ELDER COMMUNITY VOLUNTEERS

This study explored factors that determine the types of volunteer jobs older adults are placed in, as well as factors that define the meaning of their roles. With a sample of 169 elder community volunteers (mean age, 73 years), we investigated the patterns of job perceptions of women and men in two types of volunteer positions: jobs that involved leadership and jobs that did not. A two-way MANOVA with gender and leadership as independent variables revealed that there was a significant interaction effect. When men are leaders, their sense of interpersonal feedback is higher than when they are non-leaders, but their sense of influence and autonomy is lower. Women in leadership jobs feel more influential and autonomous than their peers in non-leadership jobs. Subsequent analyses probing differences in job placement suggested that work history was a significant predictor of leadership jobs for men, but not for women. Correspondingly, men with prestigious preretirement work histories perceived their volunteer roles as less influential than men who had been in lower status jobs before retirement. Work history was not a predictor of job perception for women. These placement and perception issues are discussed within the context of an historical perspective on paid work, with special emphasis on gender.     

The gist of the abnormal: Above-chance medical decision making in the blink of an eye

Very fast extraction of global structural and statistical regularities allows us to access the “gist”—the basic meaning—of real-world images in as little as 20 ms. Gist processing is central to efficient assessment and orienting in complex environments. This ability is probably based on our extensive experience with the regularities of the natural world. If that is so, would experts develop an ability to extract the gist from the artificial stimuli (e.g., medical images) with which they have extensive visual experience? Anecdotally, experts report some ability to categorize images as normal or abnormal before actually finding an abnormality. We tested the reality of this perception in two expert populations: radiologists and cytologists. Observers viewed brief (250- to 2,000-ms) presentations of medical images. The presence of abnormality was randomized across trials. The task was to rate the abnormality of an image on a 0–100 analog scale and then to attempt to localize that abnormality on a subsequent screen showing only the outline of the image. Both groups of experts had above-chance performance for detecting subtle abnormalities at all stimulus durations (cytologists d' ≈ 1.2 and radiologists d' ≈ 1), whereas the nonexpert control groups did not differ from chance (d' ≈ 0.23, d' ≈ 0.25). Furthermore, the experts’ ability to localize these abnormalities was at chance levels, suggesting that categorization was based on a global signal, and not on fortuitous attention to a localized target. It is possible that this global signal could be exploited to improve clinical performance.
