Supporting Generative Thinking About the Integer Number Line in Elementary Mathematics

This report provides evidence of the influence of a tutorial “communication game” on fifth graders’ generative understanding of the integer number line. Students matched for classroom and pretest score were randomly assigned to a tutorial (n = 19) and control group (n = 19). The tutorial group students played a 13-problem game in which student and tutor each were required to mark the same position on a number line but could not see one another's activities. To resolve discrepant solutions, tutor and student constructed agreements about number line principles and conventions to guide subsequent placements. Pre-/posttest contrasts showed that (a) tutorial students gained more than controls and (b) agreement use predicted gain. Analyses of micro-constructions during play revealed properties of student learning trajectories.     

Changes in self-regulatory cognitions as predictors of changes in smoking and nutrition behaviour

Most longitudinal, correlational studies on health-behaviour change examine effects of Time1 social-cognitive predictors on subsequent behaviour. In contrast, our research focusses on associations between changes in predictors with change in behaviour. The Health Action Process Approach (HAPA) distinguishes between motivational predictors for intention formation and volitional predictors for behavioural change and served as theoretical basis. Two online-studies were launched targeting different behaviours (low-fat diet, smoking), different samples (Study 1: N = 469; Study 2: N = 441) and different time spans (Study 1: 3 months, Study 2: 4 weeks). Data were analysed by means of structural equation modelling with latent difference scores. Both studies resulted in almost parallel prediction patterns. Change in risk awareness and change in outcome expectancies did not result in change in intentions, whereas change in self-efficacy was of crucial importance. Change in behaviour was associated with change in action planning and action control over and above the effects of intentions. In one study, increases in self-efficacy yielded increases in behaviour change. Results demonstrate that change in action planning and especially action control was of great importance for behaviour change across two different behaviours. Analysing change in social-cognitive predictors allows drawing precise conclusions for interventions.     

The ABC of Social Desires: Affiliation,Being Alone,and Closeness to Partner

We propose a triadic model of social desires directed at appetence/aversion of affiliation with friends (A), being alone (B), and closeness to one's partner (C) that account for individual differences in subjectively experienced needs for proximity and distance in serious couple relationships. The model assumes that A, B, and C can be conceptualized at the individual level as correlated latent factors measured by appetence and aversion indicators with opposite factor loadings and low shared method variance and at the couple level assuming the same measurement model and identical (co)variances for men and women. The model was confirmed with confirmatory factor analyses in a sex‐balanced internet sample of 476 individuals and a longitudinal sample of both partners of 578 heterosexual couples by assessing the ABC desires with brief appetence/aversion scales. In both samples, the desires showed expected unique associations with the Big Five personality traits, loneliness and relationship satisfaction, perceived available support by friends and partner, and attachment style toward the partner and high 1‐year stability in the longitudinal sample. We suggest that the ABC model helps to integrate research on couples' distance regulation along the lines of communal and agentic motivation.

Construction and validation of an ecological version of the Wisconsin Card Sorting Test applied to an elderly population

ABSTRACT

The goal of this project was to construct and validate an ecological version of the Wisconsin Card Sorting Test (WCST) aimed at the elderly. This was accomplished by replacing the geometric stimuli of the traditional version with stimuli belonging to the semantic category of transport vehicles, and by elimination of the color yellow. The results showed the ecological WCST version was preferred over the traditional version and older people felt less tired during test performance. In the two independent normal elderly groups, all pairs of scores that can be derived from the WCST correlated significantly with each other. Six of 11 outcome measures of the traditional WCST-128 (long) version were significantly influenced by age. By contrast, in the WCST-64 (short) version and in the ecological WCST-54 version only one measure was affected by the age variable. No significant effect of education level or gender emerged from the results in any WCST version. Again, the subjects with cognitive deterioration had lower performance in the ecological WCST-54 version than in the two traditional WCST versions. It seems reasonable to assume that the ecological version of WCST is more discriminating and has more advantages than the traditional versions. Further research on individual differences in the performance on this task will increase understanding of the components of the test, and of the variety of factors and possible deficits that could lead to an impaired performance of the test.     

Norms and conventions

One can think of the traditional logic of blame as involving three intuitively plausible claims: (1) blame is justified only if one is deserving of blame, (2) one is deserving of blame only if one is relevantly in control of the relevant causal antecedents, and (3) one is relevantly in control only if one has libertarian freedom. While traditional compatibilism has focused on rejecting either or both of the latter two claims, an increasingly common strategy is to deny the link between blame and desert expressed in (1). While I think there is something right about many of these accounts of blame, I deny that the logic of blame can be divorced from the logic of desert. On my view, blame does have a conceptual connection to desert, but its justification is practical rather than theoretical, as the libertarian condition is a matter of adopting a stance towards a person rather than having a belief about her and the “true” causes of her action. I argue that blame fundamentally requires interacting with a person from the participant perspective and that the participant perspective, understood in terms of second-personal address, involves an ontological commitment to freedom.     

Factors Associated with Psychological Distress among Women of African Descent at High Risk for BRCA Mutations

Little is known about psychological distress among women of African descent who are at high risk for a BRCA mutation. This is a group for whom breast cancer risk reduction is critical due to the group’s high rates of breast cancer mortality. Distress is important to consider as it may reduce the potential benefit of genetic counseling and negatively affect decision making related to risk reduction. The goals of the current study were to examine breast cancer-specific distress and depressive symptoms in women of African descent at who are at high risk for a BRCA mutation and to identify background factors associated with these outcomes. Participants were 148 high-risk African American and Caribbean women who were part of a larger study that offered participants BRCA counseling at no cost. Participants completed the Impact of Events Scale, which assessed breast cancer-specific distress, and the Center of Epidemiological Studies-Depression Scale, which assessed depressive symptoms. Results of analyses revealed that almost half of the sample achieved scores indicating high and clinically significant breast cancer-specific distress, while almost one-third had clinically significant depression scores. Results further showed that low income was significantly associated with cancer-specific distress, while having a cancer diagnosis was significantly associated with depressive symptoms. These results underscore the need for targeted psychological support throughout the genetic risk assessment process for this particular high-risk group.     

Correlated change of Big Five personality traits across the lifespan: A search for determinants

Correlated change between different personality traits has recently caught the attention of researchers studying personality development. We conducted two studies to examine age effects (Study 1) and effects of cognitive ability (Study 2) on this phenomenon. Results indicated that correlated change was relatively stable from adolescence through adulthood, and then increased after age 70. Second, correlated change was greater among traits that have been linked to the same developmental processes (e.g., social investment or maturation of specific neurological systems). Third, cognitive ability was negatively associated with correlated change. Collectively, our findings suggest that personality change is partly driven by broad mechanisms affecting multiple traits. Associations with age and cognitive ability provide important leads regarding the possible nature of these mechanisms.     

Examination of the Psychometric Properties of a Brief PTSD Measure on a French–Canadian Undergraduate Population

This study examines the psychometric properties of the French-Canadian Modified PTSD Symptom Scale (MPSS-FC) in a sample of French-Canadian undergraduates. Findings uncovered a 3-dimensional model for the Frequency and Severity scales, which shared factorial invariance. In addition, the MPSS-FC scales had adequate internal consistency and a satisfactory 5-week test-retest reliability. In view of its satisfactory psychometric properties, the MPSS-FC seems promising as a brief screening measure of PTSD. Indeed, the MPSS-FC as a stand-alone measure could be used with a population known to have been exposed to a traumatic event.     

The two sides of goal intentions: Intention self-concordance and intention strength as predictors of physical activity

Objective: The present research introduces an extended conceptualisation of self-concordance, which is considered an attribute not only of goals, but also of goal intentions. Based on a corresponding operationalisation, we investigate the interplay of both intention strength and intention self-concordance in the prediction of physical activity.

Design: Data were taken from a longitudinal study of 134 obese people who were asked to fill out a questionnaire three times every six months.

Main measures: Physical activity and intention self-concordance were measured by validated scales. Intentions strength was assessed by an item typically employed in the extant literature.

Results: Logistic regression analyses and path analyses showed both intention strength and self-concordance to be significant predictors of changes in physical activity over time. Additional analyses found self-efficacy to be a significant predictor of intention strength and self-concordance; for outcome expectations this was not the case.

Conclusions: Findings support the idea that intention strength and self-concordance are two critical facets of a goal intention that need to be considered in the prediction of physical activity participation. Whereas intention strength refers to the degree of determination with which a goal intention is adopted, self-concordance rather captures the quality of this intention.
