Dissociation between magnitude comparison and relation identification across different formats for rational numbers

ABSTRACT

The present study examined whether a dissociation among formats for rational numbers (fractions, decimals, and percentages) can be obtained in tasks that require comparing a number to a non-symbolic quantity (discrete or else continuous). In Experiment 1, college students saw a discrete or else continuous image followed by a rational number, and had to decide which was numerically larger. In Experiment 2, participants saw the same displays but had to make a judgment about the type of ratio represented by the number. The magnitude task was performed more quickly using decimals (for both quantity types), whereas the relation task was performed more accurately with fractions (but only when the image showed discrete entities). The pattern observed for percentages was very similar to that for decimals. A dissociation between magnitude comparison and relational processing with rational numbers can be obtained when a symbolic number must be compared to a non-symbolic display.     

11-M Victims 3 Years After Madrid Terrorist Attacks: Looking for Health Beyond Trauma

Although there is a growing body of evidence that health is the presence of well-being and not just the absence of a disease, research related to victims of terrorists attacks is mostly focused on the presence/absence of pathology (e.g. PTSD). The present study aims to apply the Complete State Model of Health to evaluate the mental health status of 69 direct victims of 11-M terrorist attack three years after the event. The results of Horn’s Parallel Analysis and CFA confirmed that the measures of positive mental health (well-being indicators) and illness (PTSD) loaded on separate but correlated factors. This is to say, the absence of PTSD in our sample was not equivalent to the presence of health. However, although positive health and illness indicators should be considered as two different factors, they were closely related. In fact, three well-being indicators were strongly associated with PTSD: positive affect, self-acceptance and positive relations. These findings suggest the need to work to ensure victims’ positive health.     

Mixed Methods in Youth Purpose: An Examination of Adolescent Self-Regulation and Purpose

Utilizing a relational developmental systems approach to examining character strengths, this article examines the connection between adolescents’ intentional self-regulation (ISR) with youth sense of purpose, using data from a large-scale evaluation of a youth development program in Scotland. Data were triangulated from multiple sources, including youth surveys and interviews as well as teacher assessments. Surveys were collected from 783 S2 (approximately seventh grade) pupils; teacher survey data were collected for 732 of these pupils. Telephone interviews were conducted with a subset of 29 adolescents. The data were analyzed with an innovative mixed-methods technique that allows qualitative interview data to underscore consistencies and disconnects with quantitative findings from both teacher and adolescent surveys. Results demonstrate a strong connection between ISR and purpose and many consistencies across measures of purpose.     

Precues’ elevation of sensitivity is not only preattentive,but largely monocular

Visual sensitivity can be heightened in the vicinity of an appropriate precue. Experiments with multiple, noninformative precues suggest that this facilitation should not be attributed to focal attention. The number of simultaneously appearing precues seems to be irrelevant; contrast thresholds are lowest for targets that appear in a precued position. Here we report that precues become less effective when they and the target are delivered to different eyes. We conclude that the mechanism responsible for such heightened sensitivity has largely monocular input.     

Cross-cultural differences in academic self-efficacy and its sources across socialization contexts

The effect of age-at-testing on verbal memory among children following severe traumatic brain injury

Memory deficits are a common sequelae following childhood traumatic brain injury (TBI), which often have serious implications on age-related academic skills. The current study examined verbal memory performance using the Rey Auditory Verbal Learning Test (RAVLT) in a pediatric TBI sample. Verbal memory abilities as well as the effect of age at-testing on performance were examined. A sample of 67 children following severe TBI (age average = 12.3 ± 2.74) and 67 matched controls were evaluated using the RAVLT. Age effect at assessment was examined using two age groups: above and below 12 years of age during evaluation. Differences between groups were examined via the 9 RAVLT learning trials and the 7 composite scores conducted out of them. Children following TBI recalled significantly less words than controls on all RAVLT trials and had significantly lower scores on all composite scores. However, all of these scores fell within the low average range. Further analysis revealed significantly lower than average performance among the older children (above 12 years), while scores of the younger children following TBI fell within average limits. To conclude, verbal memory deficits among children following severe TBI demonstrate an age-at-testing effect with more prominent problems occurring above 12 years at the time of evaluation. Yet, age-appropriate performance among children below 12 years of age may not accurately describe memory abilities at younger ages following TBI. It is therefore recommended that clinicians address child’s age at testing and avoid using a single test as an indicator of verbal memory functioning post TBI.     

Transition to motherhood: A longitudinal study

A prospective longitudinal study assessed the development of the mother-child relationship within the context of other important aspects of transition to parenthood. In the prenatal phase, 238 women who were 8 months pregnant with their first child completed a set of questionnaires. At 1 month post-partum, 165 of these women completed a second set of questionnaires, and a subset of 86 were observed for 1 hour at home with their infants. When their child was 2 years old, 62 of the 86 mothers completed questionnaires and were observed in interaction with their toddler in the laboratory. The several hundred individual variables were reduced to internally consistent composite variables, 5 in the prenatal phase, 7 postpartum, and 14 in the toddler phase. Preliminary analyses reported in this paper assessed the structure of relationships among the composite variables within each phase (Pearson correlations) and whether there was significant prediction from one dimension to another across the phases, beyond stability in the predicted dimension (multiple regressions). Causal modeling analyses are still in progress. The results indicate that the development of maternal attachment is a gradual process and that feelings of attachment are related to a number of other measures of women's psychological well-being. Parenting confidence was found to play a central role in adaptation to motherhood within each phase, as well as from the prenatal to postpartum and postpartum to toddler phases.
