Memory for a staged criminal event witnessed live and on video

Memory for a staged robbery was tested in two groups of participants witnessing the event either live (n = 62) or on video (n = 64). Immediately after the event participants filled out a questionnaire probing memory with emphasis on the timing of the event and robber characteristics. The results showed that participants who watched a video recording of the event reported more details and with a higher accuracy than participants who were present on the scene, but the pattern of memory errors were similar in the two conditions. It is concluded that laboratory experiments may overestimate the memory of eyewitnesses but are otherwise able to simulate essential aspects of memory performance in naturalistic contexts.     

Frames of reference for self-evaluation of ability in mathematics

Measures of eight frame-specific self-evaluations of ability in mathematics were used to predict general mathematics self-concept and self-efficacy. Participants were 900 Norwegian students in Grade 6 (n = 277), Grade 9 (n = 236), Grade 11 (n = 263), and adult students attending senior high school (n = 124). Four items measured frame-specific self-evaluation of achievement based on external frames of reference whereas four items measured frame-specific self-evaluation based on internal frames of reference. Regression analyses were used to test relations between the frame-specific self-evaluations and general mathematics self-concept and self-efficacy. The analyses indicated that self-evaluation based on comparison with other students in class (an external frame of reference) and on comparison of mathematics achievement with achievement in other school subjects (an internal frame of reference) were robust predictors of both mathematics self-concept and self-efficacy. The analyses also indicated that students are using multiple frames of reference when evaluating their mathematics ability. Implications of the result for the internal-external frame of reference model are discussed.     

Mathematics anxiety and coping strategies among middle school students: relations with students’ achievement goal orientations and level of performance

The purpose of this study was to explore relations between students’ prior grades in mathematics, achievement goal orientations in math classes, math anxiety, and students coping strategies in math classes. Three achievement goal orientations (mastery goals, performance-approach goals, and performance-avoidance goals) and two coping strategies (problem-focused and self-protective strategies) were explored. Participants in the study were 939 middle school students. The study was designed as a cross-sectional survey. Data were analyzed by means of zero order correlations and structural equation modeling. The correlations between the three goal perspectives and between the two coping strategies were low. A mastery goal perspective strongly predicted the use of adaptive problem-focused coping strategies whereas this perspective predicted lower levels of math anxiety and less use of maladaptive self-protective coping strategies. A performance-avoidance goal perspective predicted higher math anxiety and more use of self-protective coping strategies. Performance-approach goals were not significantly related to math anxiety or to selfprotective coping strategies. However, they were weakly and negatively associated with problem-focused coping strategies. Prior math grades were positively associated with mastery goals and performance-approach goals and negatively associated with performance-avoidance goals and math anxiety. No direct associations were found between grades and the coping strategies. The associations were indirect, mediated through mastery goals, performance-avoidance goals, and math anxiety.

Method effects: the problem with negatively versus positively keyed items

Using confirmatory factor analyses, we examined method effects on Rosenberg's Self-Esteem Scale (RSES; Rosenberg, 1965) in a sample of older European adults. Nine hundred forty nine community-dwelling adults 60 years of age or older from 5 European countries completed the RSES as well as measures of depression and life satisfaction. The 2 models that had an acceptable fit with the data included method effects. The method effects were associated with both positively and negatively worded items. Method effects models were invariant across gender and age, but not across countries. Both depression and life satisfaction predicted method effects. Individuals with higher depression scores and lower life satisfaction scores were more likely to endorse negatively phrased items.     

Exercise imagery and its correlates in older adults

Objectives

The purpose of the present study was to test a structural model examining the interrelationships between exercise imagery, self-reported exercise behaviour and well-being in older adults.

Design

Cross-sectional survey.

Method

Participants were 499 older Greek adults (50.10% males) aged between 51 and 84 years (M age = 57.31; SD = 5.52) who completed questionnaires measuring exercise imagery use, exercise behaviour, subjective vitality, and physical self-worth. The relationship between these variables was tested with a structural model based on the applied model of imagery use for exercise (Munroe-Chandler & Gammage, 2005).

Results

Energy imagery positively predicted exercise behaviour and subjective vitality, and appearance and technique imagery positively predicted physical self-worth.

Conclusions

These results indicate older adults engage in different types of imagery to motivate themselves to exercise and improve their well-being, thus implying that the content of imagery interventions should be specifically tailored to the outcomes older adults wish to realise for interventions to be effective.     

Students’ perception of instrumental support and effort in mathematics: the mediating role of subjective task values

Recent research shows that teacher support is predictive of student outcomes, such as engagement and effort. In this study, we explored the relation between students’ perceptions of teacher instrumental support in mathematics lessons and their effort in mathematics. We also tested whether this relation was mediated through students’ perception of the utility value, cost, and intrinsic value of mathematics. The study was designed as a cross-sectional survey. The participants included 309 9th and 10th grade Norwegian high school students. Three dimensions of mathematics task values were measured: utility value, intrinsic value, and the cost of working with mathematics. The data were analyzed by means of structural equation modeling. Instrumental support was directly and positively related to both the utility value and the intrinsic value of mathematics. However, it was only indirectly related to the perceived cost of working with mathematics, mediated by the utility value and the intrinsic value. Instrumental support was also both directly and indirectly related to effort. The indirect relation was mediated by the students’ perception of mathematics task values.     

Processing of compound visual stimuli by children with autism and Asperger syndrome

A typical modes of visual processing are common in individuals with autism. In particular, and unlike typically developing children, children with autism tend to process the parts of a complex object as a priority, rather than attending to the object as a whole. This bias for local processing is likely to be due to difficulties in assembling subparts into a coherent whole, as proposed by Frith ( 10 1989) using the term “weak central coherence” or WCC. This study was aimed to better characterize the processing of complex visual stimuli by children with autism. Thirteen children with autistic spectrum disorders were individually paired with children of two control groups, one matched on verbal mental age (VMA) and one matched on chronological age (CA). Participants from the three groups were tested in two tasks. The first task involved hierarchical global/local stimuli, inspired by Navon ( 30 1977). The second task employed compound face‐like or geometrical stimuli. This task emphasized the processing of configural properties of the stimuli (i.e., spatial relationships). Children from the three groups showed a perceptual bias favouring the global dimension of the stimuli in the first task. By contrast, children with autism were deficient compared to normal children for the processing of the configural dimensions of the stimuli in the second task. These results suggest that visual cognition of children with autism is characterized by a dissociation between global and configural processing, with global processing being preserved and configural processing being altered in these children, therefore delineating the extents and limits of the WCC theory (Frith, 10 1989).
