Correlations among family environment, academic achievement, and academic attainment in a large sample of young Australian adults

In a set of interrelated Australian and Spanish investigations in 2001-2004, relationships were examined among intellectual ability, family environment, and academic achievement. This follow-up study used longitudinal data from young Australian adults (4,397 men, 4,703 women; M age = 20.2 yr., SD = 0.4), to investigate relationships among earlier academic achievement, family influences, and academic attainment. From multiple regression and commonality analyses the findings indicated that earlier achievement and family influences were important as separate variables in explaining differences in later academic attainment (18.6% and 14.8%, respectively, for men; 14.5% and 11.5%, respectively, for women). In addition, earlier achievement and family influences reinforced each other to account for additional shared variance (9.1% for men, 6.3% for women) in young Australian adults' academic attainment.     

A taste of words: linguistic context and perceptual simulation predict the modality of words

Previous studies have shown that object properties are processed faster when they follow properties from the same perceptual modality than properties from different modalities. These findings suggest that language activates sensorimotor processes, which, according to those studies, can only be explained by a modal account of cognition. The current paper shows how a statistical linguistic approach of word co-occurrences can also reliably predict the category of perceptual modality a word belongs to (auditory, olfactory-gustatory, visual-haptic), even though the statistical linguistic approach is less precise than the modal approach (auditory, gustatory, haptic, olfactory, visual). Moreover, the statistical linguistic approach is compared with the modal embodied approach in an experiment in which participants verify properties that share or shift modalities. Response times suggest that fast responses can best be explained by the linguistic account, whereas slower responses can best be explained by the embodied account. These results provide further evidence for the theory that conceptual processing is both linguistic and embodied, whereby less precise linguistic processes precede precise simulation processes.     

Career Aspirations of Adolescent Girls: Effects of Achievement Level,Grade, and Single-Sex School Environment

The career aspirations of high-achieving adolescent girls were explored by comparing them to the aspirations of adolescent boys as well as by looking at the influence of grade in school, achievement level, and an all-girls school environment. The participants' ideal and real career aspirations, scored in terms of prestige, were investigated via 2 sets of analyses , with coed (n = 704) and single-sex female (n = 494) adolescent samples. Results showed that high-achieving girls exceeded the aspirations of average-achieving girls and boys, and were the same as those of high-achieving boys. Gender and grade differences in ideal and real career choices over all achievement levels are also reported and discussed. Girls at single-sex schools had higher real career aspirations than did girls and boys at coed schools.     

Delayed memory for visual—haptic exploration of familiar objects

Long-term memory of haptic, visual, and cross-modality information was investigated. In Experiment 1, subjects briefly explored 40 commonplace objects visually or haptically and then received a recognition test with categorically similar foils in the same or the alternative modality both immediately and after 1 week. Recognition was best for visual input and test, with haptic memory still apparent after a week's delay. Recognition was poorest in the cross-modality conditions, with performance on the haptic-visual and visual-haptic cross-modal conditions being nearly identical. Visual and haptic information decayed at similar rates across a week delay. In Experiment 2, subjects simultaneously viewed and handled the same objects, and transfer was tested in a successive cue-modality paradigm. Performance with the visual modality again exceeded that with the haptic modality. Furthermore, initial errors on the haptic test were often corrected when followed by the visual presentation, both immediately and after 1 week. However, visual test errors were corrected by haptic cuing on the immediate test only. These results are discussed in terms of shared information between the haptic and visual modalities, and the ease of transfer between these modalities immediately and after a substantial delay.     

Sex and achievement domain: Cognitive patterns of success and failure

Subjects (N=439) were asked to write an account of an achievement of failure, and to describe it in terms of locus of standards (internal-external), conceptual focus (process-impact), and initial expectations for success (or failure). Additionally, accounts were classified on the basis of achievement domain (personal, interpersonal, mastery). Analyses of variance [2 (sex)×3 (domain)] for each cognitive measure revealed few sex differences. However, cognitive responses did vary as a function of achievement domain. Main effects for domain were observed under success instructions for locus of control (p<.0002) and under failure instructions for locus of control (p<.05), conceptual focus (p<.05), and expectations (p<.06). Interaction effects of sex and achievement domain were observed on locus of standards for success (p<.0002) and initial expectations preceding failure (p<.025), indicating that women were more responsive to domain differences than were men. Discriminant analyses indicated that cognitions were more readily patterned in terms of achievement domain than sex. Elaboration and incorporation of the concept of domain in cognitive models of achievement is suggested.     

Development of self-perceived ability in elementary school: the role of parents’ perceptions,teacher evaluations,and intelligence

The present study examined the importance of different sources of information for the development of children's self-perceptions of early school-related ability. In a sample of German elementary school children (N = 595) it was demonstrated that the associations between pupils’ ability self-perceptions on the one hand and parents’ perception of their children's ability, pupils’ intelligence and teacher-rated school achievement on the other increased throughout elementary school. In a second step, commonality analyses were employed in two subsamples (N = 416 and N = 145) to partition variance in children's self-perceptions that was specifically explained by either teacher-rated school achievement or parents’ perceptions, or by both variables. The results support the assumption that the importance of teacher evaluations for children's ability self-perceptions increases while the importance of parents’ perceptions decreases during the early school years.     

Infant development of configural object processing in visual and visual-haptic contexts

Infants’ visual processing of objects is characterised by a developmental trend from a predominantly analytical to a configural processing mode. In two studies with 6- and 8-month-old infants, we sought to replicate this finding in a purely visual condition (inspecting objects), and to examine how far redundant visual-haptic information present in a visual-haptic condition influences the processing mode. Infants were familiarized with two objects differing in three dimensions (texture, size and shape). At test, infants were presented with a familiar object, a switch object consisting of a recombination of familiar dimensions, and a novel object, and looking times were measured. Results indicate a transition from analytical processing at 6 months to configural processing at 8 months in the visual condition. In the visual-haptic condition, both age-groups displayed configural processing. Thus, redundant visual-haptic information seems to enhance object processing.     

Category typicality effects in children's memory performance: Qualitative and quantitative differences in the processing of category information

Kindergarten, third, and sixth graders (6, 9, and 12 years of age, respectively) received a cue-at-input/cue-at-output recall task, using category typical and atypical items that were based on either (1) children's conceptions of item typicality, or (2) adults' conceptions of item typicality. At each grade level, recall was greater with the child-defined lists than with the adult-defined lists, and typical items were recalled to a greater extent than atypical items. Further analyses items were recalled to a greater extent than atypical items. Further analyses revealed that the recall of typical items varied as a function of children's typicality ratings of items, and that the “typicality effect” in the adult-norm condition was due primarily to the childrennot realizing that many of the atypical items were appropriate category exemplars. In contrast, typicality effects in the child-norm condition were attributed to qualitative differences in the judged “goodness of example” of the typical and atypical items. The results were discussed in terms of the appropriateness of typicality as a dimension of children's natural language concepts, the role of age differences in knowledge base in affecting performance on a cognitive task, and of the importance of using child-generated norms in studies of children's processing of category information.     

Categorization by schema relations and perceptual similarity in 5-year-olds and adults: A study in vision and in audition

This research explores the way in which young children (5 years of age) and adults use perceptual and conceptual cues for categorizing objects processed by vision or by audition. Three experiments were carried out using forced-choice categorization tasks that allowed responses based on taxonomic relations (e.g., vehicles) or on schema category relations (e.g., vehicles that can be seen on the road). In Experiment 1 (visual modality), prominent responses based on conceptually close objects (e.g., objects included in a schema category) were observed. These responses were also favored when within-category objects were perceptually similar. In Experiment 2 (auditory modality), schema category responses depended on age and were influenced by both within- and between-category perceptual similarity relations. Experiment 3 examined whether these results could be explained in terms of sensory modality specializations or rather in terms of information processing constraints (sequential vs. simultaneous processing).     

The representation of category typicality in the frontal cortex and its cross-linguistic variations

When asked to judge the membership of typical (e.g., car) vs. atypical (e.g., train) pictures of a category (e.g., vehicle), native English (N = 18) and native Chinese speakers (N = 18) showed distinctive patterns of brain activity despite showing similar behavioral responses. Moreover, these differences were mainly due to the amount and pervasiveness of category information linguistically embedded in the everyday names of the items in the respective languages, with important differences across languages in how pervasive category labels are embedded in item-level terms. Nonetheless, the left inferior frontal gyrus and the bilateral medial frontal gyrus are the most consistent neural correlates of category typicality that persist across languages and linguistic cues. These data together suggest that both cross- and within-language differences in the explicitness of category information have strong effects on the nature of categorization processes performed by the brain.     

Strategies in cross-modality matching

Subjects were tested on cross-and within-modality matching conditions with either a 5-sec or a 20-sec delay imposed between standard and comparison stimuli. Half the subjects were informed before the trial of what the comparison modality would be, while the others were not. There was a strong effect of instructions on the cross-modality conditions, but little on the within-modality conditions. The informed subjects showed better performance in the haptic-visual condition, while for the uninformed subjects, visual-haptic performance was better. The results suggest the importance of subjects’ processing strategies in cross-modality performance.     

Reflection-impulsivity and academic attainment in emotionally disturbed children

Sixty-five emotionally disturbed children were administered the Matching Familiar Figures Test (MFF) and standard achievement tests. Significant correlations were obtained between MFF errors and achievement and Mental Age (MA) but not between MFF latencies and achievement and MA. Fifteen impulsive and fifteen reflective children, matched on MA and not differing on Chronological Age (CA), did not differ on their levels of academic achievement. However, the reflective group was found to be two grades above the impulsive group in actual grade placement. Results are discussed in terms of possible behavioral differences and their consequences for the individual.     

Multidimensional similarity: an experimental and theoretical comparison of vector,distance, and set theoretical models : I. Models and internal consistency of data

In an experiment (conducted by the senior author) subjects were instructed to give three kinds of quantitative judgment on pairs of simple geometrical stimuli: similarity, commonality ratio and magnitude ratio. It was assumed that the different kinds of judgments could be interpreted in terms of one cognitive structure, and that formal models for each of these judgments should be validated by predicting one kind of judgment from knowledge of another kind of judgment. The present report proposes two different, though related, systems of formal models for similarity, commonality and magnitude ratio judgments. One, called E-model, interprets the judgments in terms of set- and vector-representations, and connections between them; the other, called R-model, interprets the judgments in terms of set- and distance-representations and their connections. The results are slightly in favor of the E-model. In a subsequent paper, the authors will report the results of multidimensional analyses for the same data, which slightly favor the R-model.     

Gender differences in autonomous and social achievement orientations

This research examined gender differences in orientations toward autonomous and social achievement. Three independent samples of subjects (total N= 359 males and 574 females) completed measures of achievement orientation (including Strumpfer's [1975] Autonomous Achievement Values and Social Achievement Values scales) and relevant cognitive, affective, and behavioral variables. Correlational and factor analyses clearly identified distinct autonomous and social achievement factors for both men and women in each of the samples. Examination of the correlates of achievement orientation indicated that whereas an autonomous achievement orientation is similarly expressed in males and females, there are considerable sex differences in the expression of an orientation toward social achievement. In particular, a social achievement orientation was associated with concerns over social approval and responsiveness to social influence among males, but was generally unrelated to these factors among females. Findings are discussed in terms of several recent hypotheses concerning the effects of sex role norms on the development and expression of achievement needs in men and women.     

Moved to action? Gender differences in perceived effort and motor performance after video-based achievement motive arousal

Achievement incentives in sports are assumed to trigger achievement motivation, which in turn increases performance. We used a within-subject-design to test achievement motive arousal (using an A-B-A design) using video clips. We hypothesized that an ACH-video clip arouses the achievement motive (PSE) stronger, leads to better performance in a skipping task and elicits stronger perceived effort and commitment for the task than the NEUTRAL- and NO-video conditions. We investigated gender differences. 184 students (92 women, age: M = 27.66 years, SD = 9.72) participated in a three-part web-survey. Neither main nor interaction effects of Video-Condition and Gender were found on motive arousal and skipping frequency. Significant interaction effects on skipping slope and perceived effort, however, showed that women are more engaged after the ACH-video than after the NEUTRAL-video and NO-video and here even outperformed men. Results are discussed in terms of why external “motivators” (e.g., videos) affect men and women differently.     

Features of graded category structure: Generalizing the family resemblance and polymorphous concept models

Many real-world categories contain graded structure: certain category members are rated as more typical or representative of the category than others. Research has shown that this graded structure can be well predicted by the degree of commonality across the feature sets of category members. We demonstrate that two prominent feature-based models of graded structure, the family resemblance (Rosch & Mervis, 1975) and polymorphous concept models (Hampton, 1979), can be generalized via the contrast model (Tversky, 1977) to include both common and distinctive feature information, and apply the models to the prediction of typicality in 11 semantic categories. The results indicate that both types of feature information play a role in the prediction of typicality, with common features weighted more heavily for within-category predictions, and distinctive features weighted more heavily for contrast-category predictions. The same pattern of results was found in additional analyses employing rated goodness and exemplar generation frequency. It is suggested that these findings provide insight into the processes underlying category formation and representation.

The effects of age on sensory thresholds and temporal gap detection in hearing, vision, and touch

Differences in sensory function between young (n 5 42, 18&#x2014;31 years old) and older (n 5 137, 60&#x2014;88 years old) adults were examined for auditory, visual, and tactile measures of threshold sensitivity and temporal acuity (gap-detection threshold). For all but one of the psychophysical measures (visual gap detection), multiple measures were obtained at different stimulus frequencies for each modality and task. This resulted in a total of 14 dependent measures, each based on four to six adaptive psychophysical estimates of 75% correct performance. In addition, all participants completed the Wechsler Adult Intelligence Scale (Wechsler, 1997). Mean data confirmed previously observed differences in performance between young and older adults for 13 of the 14 dependent measures (all but visual threshold at a flicker frequency of 4 Hz). Correlational and principalcomponents factor analyses performed on the data from the 137 older adults were generally consistent with task and modality independence of the psychophysical measures.     

Individual and age-related differences in children’s working memory

The purpose of this study was to investigate the degree to which age-related and individual differences in children’s working memory (WM) are due to a general or task-specific capacity system. Experiment 1 correlated children’s (N=146; age range 5–19 years) verbal and visual-spatial working memory performance with various intelligence and achievement measures. The results supporting a general system were that (1) visual-spatial and verbal WM measures were significantly intercorrelated with and without age partialed out and (2) both verbal and visual-spatial WM measures were significantly correlated with diverse achievement and intelligence measures. Experiment 2 compared three age groups (N=192; 7-, 10-, and 13-year-olds) on working-memory performance tasks under initial, enhanced (cued), and maintenance conditions. The results supporting a general capacity system were that (1) age-related performance differences in WM were found on all conditions and not isolated to specific processes, (2) the maintenance measures (high-load condition) predicted the variance better in age-related performance than process measures, and (3) although individual differences in WM performance reflected two independent operations, these operations produced similar correlations to achievement within age groups. Overall, the results support a general capacity explanation of age-related and individual differences in children’s WM performance.     

Individual differences in process outcomes for verbal analogy and classification solution

Adult performance on verbal analogy and classification problems was assessed in terms of the outcomes of process execution. Measures were obtained for the accuracy of stem processing and subsequent alternative processing. The process-outcome measures obtained within each task accounted for overall performance scores and were differentially related to ability. This was shown by ability differences in the models accounting for subjects' overall accuracy and in the correlational patterns. Analogy and classification problem forms differed in the measures most important for predicting individual differences. Specifically, measures of alternative processing were more important in classification than analogy solution and application was shown to be important for analogy solution. In addition, common process-outcome measures showed the highest correlations across problem forms, consistent with the assumption that both induction tasks tap similar psychological processes. The results are discussed with respect to previous studies assessing commonality and individual differences among children in process-outcomes.
