The Relation Between Experience and Spatial Performance in Men and Women

The purpose of the present study was to test the hypothesis that environmental factors affect the magnitude of gender differences in spatial performance only when the tasks used are susceptible to the influence of such factors. Two hundred and ninety White middle-class undergraduate students (165 females, 125 males) completed the Vandenberg and Kuse Mental Rotations Test (MRT), a paper and pencil version of the Water Level Task (WLT), and toys and sports preference questionnaires. Results revealed that males outperformed females on both spatial tests. In addition, a main effect of toys preference showed that participants with a spatial toys preference outperformed those with a nonspatial preference on both the MRT and the WLT. This main effect was qualified by an interaction between this factor and gender. The interaction was found only on the WLT and showed that gender differences were only significant in participants with a nonspatial preference. An interaction of sports preference and gender was also observed. This interaction revealed that, in contrast to what was obtained with toys, gender differences on both spatial tests were significant only in participants with a spatial sports preference. Implications of these findings with regard to the development of gender differences in spatial abilities are discussed.     

Construct validity of perceptual style: Role of stimulus size in the embedded-figures test and the rod-and-frame test

Three experiments were performed in order to test the construct validity of perceptual field dependence (FD) and field independence (FI). In Experiment 1, performance of subjects on two sizes of Form A of Witkin’s Embedded Figures Test (EFT) with a size-ratio of 1 to 4 was compared. The size of the standard EFT was taken as unity. A nonsignificant size effect was found for all subjects as a group, and a significant rank correlation was found between performances on the two sizes of the EFT. Furthermore, the performance of field-dependent subjects (as defined by performance on the standard EFT) and field-independent subjects did not interact significantly with the size factor. In Experiment 2, the physical size of the EFT changed from 1 to 8. A nonsignificant, overall size effect was again found, but the EFT performance of fielddependent and field-independent subjects interacted significantly with the size factor. In Experiment 3, the performance of subjects on two sizes of the EFT (i.e., 1 to 8) and two sizes of the standard rod-and-frame test (RFT) (i.e., 1 to 4.5) were compared. A significant stimulus-size effect was found in the EFT, with all subjects becoming morefield-independent, and a significant stimulus-size effect was found in the RFT with the same subjects becoming morefield-dependent. Finally, the EFT performance of the field-dependent and field-independent subjects again displayed a significant interaction with the size of the embedded figures. A parallel-serial processingstyles hypothesis is proposed to account for the EFT data.     

A Validity and Multiple Regression Study of Performance in the GEPI as a Predictor for Performance on the GED

This study attempts to determine the relationship between the subtests of the General Education Performance Index (GEPI) and the revised version of the General Educational Development Test (GED), and reports a technique whereby performance on the GEPI may be used to predict performance on the GED. Participants were men and women, aged 16 to 62, who were given the GEPI and then the GED. Multiple regression equations were generated to predict GED scores using age and each GEPI score. No significant correlation was found between age and GED scores or between age and GEPI scores, but a highly significant correlation (p > .001) was found between each GEPI subtest score and the subsequent score attained on the GED. Regression equations for each subtest and cross validation that demonstrated high predictive validity for each regression equation are reported.     

Dimensions of need for power: Personalized vs. socialized power in female and male managers

Sex differences in two dimensions of need for Power—Socialized Power (s Pwr) and Personalized Power (p Pwr)—were examined for a sample of 124 managerial women and men. Correlations with job satisfaction were analyzed as well as the ability of two versions of the thematic apperception test (TAT) to measure both s Pwr and p Pwr. Results show that female managers are higher than male managers in the “desirable” s Pwr need and the same in the “less desirable” p Pwr. Socialized Power correlates significantly with job satisfaction for the males, but not for the females. Personalized Power shows no significant correlation for either gender. Both versions of the TAT are interchangeable and scores are comparable for s Pwr and p Pwr.     

Differential correlates of irrational belief

One hundred and ten students completed a battery which included Jones' Irrational Belief Test (IBT), and measures of subjective well-being, affect, alienation, personality, goal characteristics, and goat attainment. Correlations and canonical composites showed a general relationship between irrational beliefs and emotional difficulty, but the specific pattern differed for subgroups of IBT scales. Correlations supported the construct validity of IBT scales, but suggested they also reflect motives, conflicts, affects and personality characteristics. Interdependence of these processes was hypothesized and use of subscore composites rather than total IBT scores was suggested.

Quantitative and qualitative analyses of clock drawings in Alzheimer's and Huntington's disease.

Although visuoconstructive impairment has been reported in both Alzheimer's (DAT) and Huntington's (HD) disease, there is little knowledge concerning how this cognitive deficit differs quantitatively and qualitatively in these two progressive dementias. To address this issue, the present study compared performances on the Clock Drawing Test (CDT: command and copy) of 25 DAT patients, 25 equally demented HD patients, and 25 elderly normal controls (NC). In the command condition, both patients groups were significantly impaired compared to the NC group. Although there was no significant difference between DAT and HD patients' total quantitative scores, a qualitative error analysis revealed a number of dissociations between the two patient groups. Graphic difficulties, very common in HD patients, were virtually absent in DAT patients; in contrast, conceptual errors were almost exclusively seen in DAT patients and were related to the severity of their dementia. Perseveration and "stimulus-bound" responses were also more frequent in DAT patients, and both groups made visuospatial errors. In the copy condition, the DAT, but not the HD, patients evidenced a marked improvement in performance. These results indicate that while both DAT and HD patients have significant visuoconstructive difficulties even in the early stages of their disorders, the specific cognitive processes underlying their quantitative impairments are quite different. It is possible that the DAT patients' conceptual errors are yet another indicator of the deterioration of their semantic knowledge.     

The mediational role of executive functions for the relationship between motor ability and academic performance in pediatric cancer survivors

IntroductionPediatric Cancer Survivors (PCS) bear a high risk for late effects within motor abilities (MAs) and executive functions (EFs). In typically developing children, these domains are interrelated and predictors of academic performance. The current study investigated (i) whether MAs and EFs are also interrelated in PCS, and (ii) whether EFs mediate the relation between MAs and academic performance.Methods78 PCS (7–16 years; M = 11.23; SD = 2.49) participated in this study. Three MAs were assessed: coordination and strength (using the German Motor Test) and endurance (using a cycle ergometer test). EFs were assessed: inhibition and cognitive flexibility (Color-Word Interference Test) and working memory (Block Recall test); and academic performance by questionnaire asking for children’s grade point average.ResultsPearson correlations revealed associations of coordination and strength with EFs and associations of all three MAs with academic performance. A multiple regression model revealed that among the three MAs, coordination was the only significant predictor of EFs (β = 0.42, p = .001). Lastly, mediation analyses revealed that the association of MAs with academic performance was mediated by EFs (indirect effect: β = 0.167, p = .003). Regarding individual motor abilities, this was only true for coordination and strength, but not for endurance.ConclusionResults show that MAs and EFs are interrelated in PCS and that EFs mediate the relationship between coordination and strength with academic performance. This may be important for the design of future physical activity interventions to improve MAs, EFs and academic performance.     

A test of a neo-Piagetian model of the water-level task

A neo-Piagetian model (Pascual-Leone & Morra, 1991 Pascual-Leone, J. and Morra, S. 1991. “Horizontality of water level: A neo-Piagetian developmental review”. In Advances in child development and behavior, Edited by: Reese, H. W. Vol. 23, 231–276. San Diego, CA: Academic Press.  [Google Scholar]) of the Water-level task (WLT) predicts that WLT performance depends on three factors: physical knowledge, field independence, and M capacity. The latter is an attentional capacity construct defined in neo-Piagetian theories. The model predicts that a minimum M capacity is necessary for accurate performance on WLT items. It also predicts that M capacity mediates the relationship between field independence and physical knowledge on one side and WLT on the other. Tests of field independence and M capacity, a paper-and-pencil version of the WLT, and a set of questions on the liquid horizontality principle were administered to 337 participants, aged 5 to 13 years. Six predictions derived from the model were tested; all of them were supported by the data, with only one exception, namely, on items with sideways and capsized bottles the M capacity required for accurate performance was one unit lower than predicted. It is concluded that the results strongly support the model under consideration, but suggest an amendment to one of its details. Gender differences were also examined; a small but significant gender difference in the WLT remained when field independence, physical knowledge, and M capacity were controlled for.     

Theory of Mind and conduct problems in children: Deficits in reading the “emotions of the eyes”

A significant clinical feature of disorders of antisocial behaviour involves difficulties in social functioning. It has been suggested that deficits in “theory of mind” (ToM) reasoning—the ability to decode others’ emotions and thoughts—may underlie social difficulties in these populations. Success in demonstrating ToM impairment associated with antisocial behaviour and psychopathy in adults and children have been limited. In the current study, parent-reported conduct problems were concurrently measured with performance on an advanced test of ToM developed for children, the Child Eyes Test (Journal of Developmental and Learning Disorders, 5, 47–78). Preadolescent and young adolescent children (n=79) drawn from a community sample were required to identify emotions from photographic stimuli depicting the eye region of the face only. Findings suggested a generalised impairment in ToM in children with conduct problems, as indicated by a significant relationship between poor Eyes Test performance and conduct problems, even when IQ, sex and age were controlled for. The findings are discussed in the context of the amygdala theory of psychopathy, and the neural systems suggested to mediate performance on the Eyes Test.     

Endogenous estradiol is associated with verbal memory in nondemented older men

This study examined the relationship between endogenous hormones and cognitive function in nondemented, ethnically-diverse community-dwelling older men enrolled in the Einstein Aging Study (EAS). All eligible participants (185 men, mean age=81 years) received neuropsychological assessment (Free and Cued Selective Reminding Test (FCSRT), Logical Memory (LM), Trail Making Test B (TMTB), block design (BD)) and provided blood samples for hormonal assays (total estradiol, total testosterone, calculated free testosterone index). Linear regression analysis adjusted for age, education, body mass index, and cardiovascular comorbidities indicated that men with high levels of total estradiol demonstrated better FCSRT verbal memory performance (β=0.17, p<0.02) compared to men with lower levels of total estradiol. The results remained unchanged when the model was further adjusted for ethnicity. We did not detect an association between testosterone and cognitive performance. These findings indicate that high levels of total estradiol in older men are associated with better performance on a cue-based, controlled learning test of verbal memory that is a sensitive predictor of dementia.     

Study of Spiritual Intelligence and Adjustment Among Arts and Science College Students

A study to evaluate the relationship between the spiritual intelligence and adjustment among the college students was conducted on a sample of 250 students in six various colleges of Tuticorin district, Tamil Nadu, India. Gender, religion, community, major subject, educational qualification of father and mother, student locality, college type, father and mother’s occupation and monthly family income (n = 11 variables) were chosen for the study. Test of significance for spiritual intelligence and adjustment was studied and found them nonsignificant except student locality, found to be significant. Two valid and reliable instruments were used to assess student’s spiritual intelligence and adjustment. Correlation and Chi-square analysis using structural equation model were used to analyze these data. Correlation analysis showed significant relationship between the variables among the college students (n = 250). Chi-square analysis of association between adjustments of college students showed that most variables are nonsignificant unlike father’s educational qualification and mother’s occupation. The results disclosed the significant positive relationship with spiritual intelligence and adjustment among adolescents.     

Anxiety-induced miscalculations,more than differential inhibition of intuition,explain the gender gap in cognitive reflection

The Cognitive Reflection Test (CRT) is among the most common and well-known instruments for measuring the propensity to engage reflective processing, in the context of the dual-process theory of high-level cognition. There is robust evidence that men perform better than women on this test—but we should be wary to conclude that men are more likely to engage in reflective processing than women. We consider several possible loci for the gender difference in CRT performance, and use mathematical modeling to show, across two studies, that the gender difference in CRT performance is more likely due to women making more mathematical mistakes (partially explained by their greater mathematics anxiety) than due to women being less likely to engage reflective processing. As a result, we argue that we need to use gender-equivalent variants of the CRT, both to improve the quality of our instruments and to fulfill our social responsibility as scientists.     

An investigation of the relationship between general belief patterns and well-being

One hundred and thirty-three employees (58 males, 75 females) of the Department of Veterans Affairs Medical Center (DVAMC), Coatesville, PA anonymously volunteered data on a Demographic Survey, The Brief Symptom Inventory (BSI, Derogatis), and The Irrational Beliefs Test (IBT, Jones). A canonical correlation analysis was used to investigate associations between general patterns of beliefs and symptomatology. Two significant pairs of variates were revealed. The first pair provided associations between Demand for Approval, High Self-Expectations, Frustration Reactive, Anxious Overconcern, and Perfectionism and psychological symptomatology. The second pair provided associations between Demand for Approval, Blame Proneness, Frustration Reactive, and Emotional Irresponsibility and somatic symptoms. A MANOVA was used to assess for gender differences. There was no significant general gender effect. However, univariate analyses revealed significant effects for seven BSI variables. This study supported the belief that one's pattern of thinking is related to one's pattern of symptomatology. This has implications for use in health psychology and behavioral medicine.     

Evaluation apprehension and response withholding in solution of anagrams

Sixty male Ss who were classified as high or low scorers on the Sarason Test Anxiety Scale performed a difficult anagrams task either alone, before a passively observing experimenter or in the presence of an experimenter who both observed and evaluated the S's performance. Ss who were high in test anxiety attempted fewer anagrams and had fewer correct solutions in the Evaluated condition than in the Alone condition, but also had a higher proportion of correct solutions out of total attempts. Low test-anxiety Ss did not show variable performance across conditions for any measure. Follow-up studies showed that when Ss were encouraged to attempt partial solutions neither test anxiety nor experimental treatment influenced any of the measures of performance. State anxiety change scores from baseline to post-treatment assessment showed a generally negative correlation between anxiety and number of anagrams attempted. The results indicate that fear of failure engendered by test anxiety and experimenter evaluation caused Ss to withhold responding.     

Does linguistic reversibility exist? an experimental exploration of a psycholinguistic construct

Three experiments were devised involving 176 subjects aged between 5-0 and 8-1 years to examine children's receptive control of a set of four intersentence relations (identity, antonymy, structure reversal, equivalence) and to relate this linguistic ability to levels of cognitive functioning as assessed by the Piagetian measureDeux Sens de l'Orientation. The results indicate a significant but moderate correlation between performance on the two tasks. Cognitive precedence with respect to corresponding linguistic ability was observed in only one of the experiments, where linguistic performance was unsually low due to phonological interference between the lexical items used. The results were interpreted as giving evidence of linguistic reversibility—partially independent from cognitive reversibility though isomorphic with it—in the perceptual-figurative mode, resulting in flexible and efficient processing of linguistic inversions and even converse relations by preoperational children. These data complement previous psycholinguistic research in the Piagetian tradition, which had shown cognitive precedence relative to corresponding linguistic processes. It is suggested that previous research had tapped mainly linguistic processes in the cognitive operational mode, and that future research needs to examine the interrelation between the two modes.     

Cognitive subprocesses of mental rotation: why is a good rotator better than a poor one?

The Vanderberg-Kuse Mental Rotation Test is a standard test of mental rotation ability. Recent experiments have demonstrated that mental rotation is a complex cognitive process wherein different subprocesses (focused attention, visual scanning, perceptual decision, visual memory) play important roles in performance. We classified the population as good and poor rotators by performance of mental rotation (ns = 47: 22 men and 25 women, respectively; mean age: 20.7 yr.). To examine differences cognitive subprocesses of mental rotation of these two groups were compared. There were significant differences between poor and good rotators in performance on Raven's test and the Pieron Focused Attention test scores. The good rotators scored better because their perceptual decision-analytical intelligence (Raven) and focused attention scores were higher.     

Correlates of performance on the Gollin and Mooney tests of visual closure

One hundred and twenty-seven undergraduate students variously performed a computerized version of the Gollin (1960) Incomplete Figures Test, the Mooney (1957) Test of Incomplete Face Perception, the Poppelreuter (1917) Overlapping Figures Test, and a visual search task. Performance of male subjects was superior to that of female subjects on the Mooney test but inferior on the visual search task. Correlation and regression analyses showed that the only significant predictor of Gollin test scores was latency to identify all items in the Overlapping Figures Test. There was no relationship between performances on the Gollin and Mooney tests or between Gollin or Mooney test performance and visual search latency. The Gollin and Mooney tests appear to access different perceptual processes, none of which is dependent on the efficiency of visual search.     

Irrational beliefs and psychological needs

Studied the relationship between irrational beliefs and 15 psychological needs described by Murray. The Irrational Beliefs Test (IBT) and the Adjective Check List (ACL) were administered to 46 high school students and 50 adults. Results of stepwise multiple regression analyses indicated that five IBT scales and IBT Full-Scale were significantly associated with psychological needs. It was concluded that pathological behavior could not be readily predicted on the basis of irrational beliefs. It was further concluded that Ellis' model of personality obtained additional validating evidence.
