Parents' Explanations of Their Child's Performance in Mathematics and Reading: A Replication and Extension of Yee and Eccles

This study was conducted to examine whether Finnish parents would endorse the the classic gender-related attribution pattern and explain their son's mathematical performance in terms of talent and their daughter's in terms of effort. In addition, we examined whether the pattern of attributions would be the opposite in regard to parental explanations of their child's reading performance. A group of parents (N = 486), both mothers and fathers, were requested to assess the level of competence of their 1st grader in mathematics and reading. The parents were also asked to recall events from their child's 1st school year in which the child succeeded and failed in mathematics and reading; they were then asked to evaluate the importance of talent, effort, and task to the child's outcomes. The parents of boys assessed their child's mathematical competence to be higher than did the parents of girls. Furthermore, the parents of boys rated talent as a more important reason for their child's mathematical success than did the parents of girls. In contrast, the parents of girls rated effort as a more important reason for their child's mathematical success. Although the girls were perceived to surpass boys in reading, the girls' positive outcomes in reading were explained by effort more than the boys' outcomes, and at the highest level of assessed competence, the boys' verbal talent was rated as a more significant cause of success in reading than the girls' verbal talent. In sum, our results suggested that in both mathematics and reading, girls were not entitled to ability-based attribution to the same extent as were boys.     

On the capacity of attention: its estimation and its role in working memory and cognitive aptitudes

Working memory (WM) is the set of mental processes holding limited information in a temporarily accessible state in service of cognition. We provide a theoretical framework to understand the relation between WM and aptitude measures. The WM measures that have yielded high correlations with aptitudes include separate storage-and-processing task components, on the assumption that WM involves both storage and processing. We argue that the critical aspect of successful WM measures is that rehearsal and grouping processes are prevented, allowing a clearer estimate of how many separate chunks of information the focus of attention circumscribes at once. Storage-and-processing tasks correlate with aptitudes, according to this view, largely because the processing task prevents rehearsal and grouping of items to be recalled. In a developmental study, we document that several scope-of-attention measures that do not include a separate processing component, but nevertheless prevent efficient rehearsal or grouping, also correlate well with aptitudes and with storage-and-processing measures. So does digit span in children too young to rehearse.     

The effect of time constraints and personality facets on general cognitive ability (GCA) assessment

General cognitive ability (GCA) is a recognized construct for predicting job performance and capacity to learn. However, it has recently been argued that the time constraints under which GCA is assessed might provoke test anxiety, which negatively biases GCA scores. This can then lead to erroneous rejection of qualified candidates in personnel hiring contexts. This paper aimed to investigate: (1) to what extent candidates’ GCA scores increase when tested without time constraints and the ability of this GCA score to predict job performance; and (2) the personality characteristics that hinder GCA test performance under time constraints. Results from two field studies conducted in an actual personnel selection context partially confirmed the hypotheses. They revealed that, aside from the improvement of all candidates’ GCA scores when time constraint was removed, only GCA assessed without time constraints predicts job performance. Furthermore, while all candidates’ scores were influenced by the time constraint condition, individuals who are anxious, low-impulse, low value-questioning and deliberating are more penalized by the time constraint condition of such testing and, thus, are more likely to be erroneously eliminated in a selection process.     

The effect of predictive history on the learning of sub-sequence contingencies

Two experiments demonstrated that the prior predictive history of a cue governs the extent to which that cue engages in sequence learning. Using a serial reaction time task, we manipulated the predictiveness of the stimulus locations (cues) with respect to the location of the stimulus on the next trial (outcome), such that half of the cues were good predictors of their outcomes, whilst the other half were poorer predictors. Following this, all cues were then paired with novel outcomes. Learning about those cues that were previously established as good predictors proceeded more rapidly than learning for those cues previously established as poor predictors. When the simple recurrent network is modified to include a variable associability parameter, the effects are easily modelled.     

The Reliability,Validity, Discriminant and Predictive Properties of the Social Phobia Inventory (SoPhI)

This paper reports on the psychometric properties of the Social Phobic Inventory (SoPhI) a 21-item scale that was designed to measure social anxiety according to the criteria of DSM-IV (American Psychiatric Association, APA (1994) Diagnostic and Statistical Manual of Mental Disorder , 4th Edn., Washington). Factor analysis of the SoPhI using data from a clinical sample of respondents with social phobia revealed one factor which explained approximately 59% of variance and which demonstrated strong internal reliability ( f = 0.93). The SoPhI demonstrated concurrent validity with the SPAI ( r = 0.86) and convergent validity with the Fear of Negative Evaluations-Revised ( r = 0.68). The predictive utility of the scale was demonstrated in a sample of university students classified as extroverted, normal, shy/introverted, and phobic/withdrawn ( m 2 57%). Multivariate Analysis of Variance (MANOVA) revealed that the combined university sample differed from the clinical sample on the summated scores on the SoPhI and that 43% ( m 2 ) of this difference was attributable to group membership. This figure rose to 58% attributable to group membership when these same groups were compared for differences on the 21 individual items. Scores of the SoPhI that are indicative of concern and of possible diagnostic criteria, as well as suggestions for future research, are discussed.
