Associations of non‐symbolic and symbolic numerical magnitude processing with mathematical competence: a meta‐analysis

Many studies have investigated the association between numerical magnitude processing skills, as assessed by the numerical magnitude comparison task, and broader mathematical competence, e.g. counting, arithmetic, or algebra. Most correlations were positive but varied considerably in their strengths. It remains unclear whether and to what extent the strength of these associations differs systematically between non‐symbolic and symbolic magnitude comparison tasks and whether age, magnitude comparison measures or mathematical competence measures are additional moderators. We investigated these questions by means of a meta‐analysis. The literature search yielded 45 articles reporting 284 effect sizes found with 17,201 participants. Effect sizes were combined by means of a two‐level random‐effects regression model. The effect size was significantly higher for the symbolic (r = .302, 95% CI [.243, .361]) than for the non‐symbolic (r = .241, 95% CI [.198, .284]) magnitude comparison task and decreased very slightly with age. The correlation was higher for solution rates and Weber fractions than for alternative measures of comparison proficiency. It was higher for mathematical competencies that rely more heavily on the processing of magnitudes (i.e. mental arithmetic and early mathematical abilities) than for others. The results support the view that magnitude processing is reliably associated with mathematical competence over the lifespan in a wide range of tasks, measures and mathematical subdomains. The association is stronger for symbolic than for non‐symbolic numerical magnitude processing. So symbolic magnitude processing might be a more eligible candidate to be targeted by diagnostic screening instruments and interventions for school‐aged children and for adults.     

Curriculum-Based Measurement Oral Reading as an indicator of reading achievement: A meta-analysis of the correlational evidence

This meta-analysis summarized the correlational evidence of the association between the CBM Oral Reading measure (R-CBM) and other standardized measures of reading achievement for students in grades 1–6. Potential moderating variables were also examined (source of criterion test, administration format, grade level, length of time, and type of reading subtest score). Results indicated a significant, strong overall correlation among R-CBM and other standardized tests of reading achievement and differences in correlations as a function of source of test, administration format, and reading subtest type. No differences in the magnitude of correlations were found across grade levels. In addition, there was minimal evidence of publication bias. Results are discussed in terms of existing literature and directions for future research.     

Possible relationship of elderly suicide rates with unemployment in society: a cross-national study

Analyses of individual and aggregated data have yielded an association between suicide and unemployment, particularly for men in younger age groups. Examination of the relationship of elderly suicide rates with measures of unemployment in a cross-national study of 27 countries did not produce any statistically significant association between these two variables. Also, the magnitude of the actual correlations was small. One reason for low magnitude of correlations may be better welfare systems in the studied countries which mainly reported medium and high income.     

Bidirectional experimental effects

Bidirectional experimental effects cannot be demonstrated by comparing measures of central tendency. Three approaches to the problem were considered: a test of homogeneity of variance, a comparison of control and experimental quartile frequencies by means of the chi-square test of association, and the cumulative-percentage-difference (CPD) curve--a graphic tool for demonstrating bidirectional effects. Two tests of significance were developed based on the CPD curve's maximum and minimum values. All 3 tests were first put to use analyzing simulated data, which incorporated 6 different patterns of experimental effect. The results of 100 repetitions of the simulations are summarized. Next, the results of a lexical-decision experiment with partial-word preview were analyzed using the procedures considered. The report ends with a presentation of guidelines for the use of the bidirectional tests.     

Comparing Personality Test Formats and Warnings: Effects on criterion‐related validity and test‐taker reactions

The potential for applicant response distortion on personality measures remains a major concern in high‐stakes testing situations. Many approaches to understanding response distortion are too transparent (e.g., instructed faking studies) – or are too subtle (e.g., correlations with social desirability measures as indices of faking). Recent research reveals more promising approaches in two methods: using forced‐choice (FC) personality test items and warning against faking. The present study examined effects of these two methods on criterion‐related validity and test‐taker reactions. Results supported incremental validity for an FC and Likert‐scale measure in warning and no‐warning conditions, above and beyond cognitive ability. No clear differences emerged between the FC vs Likert measures or warning vs no‐warning conditions in terms of validity. However, some evidence suggested that FC measures and warnings may produce negative test‐taker reactions. We conclude with implications for implementation in selection settings.     

Demonstrating specific cognitive deficits: a psychometric perspective

Cognitive deficits associated with psychopathology often do not occur in isolation. Consequently, identifying a specific deficit in a disorder requires comparing the magnitude of group differences on theoretically relevant measures with those on control tasks measuring other constructs. L. J. Chapman and J. P. Chapman (1973) noted that common forms of such Group x Task interactions are theoretically ambiguous unless performance measures have comparable discriminating power. The principles of psychometric matching for discriminating power developed in the Chapmans' research program are reviewed, and both criticisms and alternative psychometric approaches are evaluated. Psychometric matching can be mindful of threats to the construct validity of measures and frequently remains methodologically necessary. Otherwise, interactions involving measures that vary in sensitivity to individual differences may be misinterpreted as evidence for specific deficits.     

Is more always up? Evidence for a preference of hand-based associations over vertical number mappings

It has been argued that the association of numbers and vertical space plays a fundamental role for the understanding of numerical concepts. However, convincing evidence for an association of numbers and vertical bimanual responses is still lacking. The present study tests the vertical Spatio-Numerical-Association-of-Response-Codes (SNARC) effect in a number classification task by comparing anatomical hand-based and spatial associations. A mixed effects model of linear spatial-numerical associations revealed no evidence for a vertical but clear support for an anatomical SNARC effect. Only if the task requirements prevented participants from using a number-hand association due to frequently alternating hand-to-button assignments, numbers were associated with the vertical dimension. Taken together, the present findings question the importance of vertical associations for the conceptual understanding of numerical magnitude as hypothesised by some embodied approaches to number cognition and suggest a preference for ego- over geocentric reference frames for the mapping of numbers onto space.     

Intensity resolution and subjective magnitude in psychophysical scaling

Several successful theories of psychophysical judgment imply that exponents of power functions in scaling tasks should covary with measures of intensity resolution such asd’ in the same tasks, whereas the prevailing metatheory of ideal psychophysical scaling asserts the independence of the two. In a direct test of this relationship, three prominent psychophysical scaling paradigms were studied: category judgment without an identification function, absolute magnitude estimation, and cross-modality matching with light intensity as the response continuum. Separate groups of subjects for each scaling paradigm made repeated judgments of the loudnesses of the pure tones that constituted each of two stimulus ensembles. The narrow- and wide-range ensembles shared six identical stimulus intensities in the middle of each set. Intensity resolution, as measured byd’-like distances, of these physically identical stimuli was significantly worse for the wide-range set for all three methods. Exponents of power functions fitted to geometric mean responses, and in magnitude estimation and cross-modality matching the geometric mean responses themselves, were also significantly smaller in the wide-range condition. The variation of power function exponents, and of psychophysical scale values, for stimulus intensities that were identical in the two stimulus sets with the intensities of other members of the ensembles is inconsistent with the metatheory on which modern psychophysical scaling practice is based, although it is consistent with other useful approaches to measurement of psychological magnitudes.     

The SNARC effect does not imply a mental number line

In this study, we directly contrast two approaches that have been proposed to explain the SNARC effect. The traditional direct mapping account suggests that a direct association exists between the position of a number on the mental number line and the location of the response. On the other hand, accounts are considered that propose an intermediate step in which numbers are categorized as either small or large between the number magnitude and the response representations. In a magnitude comparison task, we departed from the usual bimanual left/right response dimension and instead introduced the unimanual close/far dimension. A spatial-numerical association was observed: small numbers were associated with a close response, while large numbers were associated with a far response, regardless of the movement direction (left/right). We discuss why these results cannot be explained by assuming a direct mapping from the representation of numbers on a mental number line to response locations and discuss how the results can be explained by the alternative accounts.     

The Role of Relationships in Understanding the Alexithymia–Depression Link

Alexithymia is associated with increased depressive symptoms in both clinical and community samples. One way that alexithymia may lead to depression is through its impact on interpersonal relationships. Individuals with alexithymia report lower perceived social support, intimacy, and relationship satisfaction. Furthermore, poor relationship functioning is a clear risk factor for depressive symptoms. Given the established alexithymia–depression link and marital dysfunction–depression link, a logical next step is to examine whether relationship dysfunction (low social support, intimacy, negative relationship behaviours, and relationship dissatisfaction) mediates the association between alexithymia and depressive symptoms. The hypothesized mediation model was assessed in a sample of 104 community couples with two analytical approaches—first with cross‐sectional measures using path analysis and second with daily diary measures collected over a seven‐day period using a multilevel modelling approach. Poor relationship functioning mediated the association between alexithymia and depressed mood in the daily diary data and partially mediated that association with the cross‐sectional measures. These results identify alexithymia as an important variable in understanding the marital functioning–depression association, and this finding has implications for treatment.

Parent Reports and Laboratory Assessments of Child Temperament: A Comparison of Their Associations With Risk for Depression and Externalizing Disorders

Parent reports and laboratory assessments of child temperament traits were compared in terms of their associations with 2 indices of risk for future maladjustment: maternal history of depression and disruptive school behavior. A community sample of 99 pre-school-aged children completed a standardized battery of laboratory tasks designed to tap positive emotionality (PE) and anger. Parent reports of child temperament were collected, and maternal history of depression was assessed using structured clinical interviews. An average of 18.5 months after the initial laboratory assessment, teacher reports of disruptive school behavior were collected. Structural equation models were used to test the association between the 2 assessment approaches of child temperament and maternal history of depression and disruptive school behavior. Laboratory measures and parent reports of anger were equally good at predicting disruptive school behavior, while laboratory measures of PE showed stronger associations with maternal history of depression than parent report.     

The Magnitude and Extent of Cheating and Response Distortion Effects on Unproctored Internet‐Based Tests of Cognitive Ability and Personality

The use of unproctored internet‐based testing (UIT) for employee selection is quite widespread. Although this mode of testing has advantages over onsite testing, researchers and practitioners continue to be concerned about potential malfeasance (e.g., cheating and response distortion) under high‐stakes conditions. Therefore, the primary objective of the present study was to investigate the magnitude and extent of high‐ and low‐stakes retest effects on the scores of a UIT speeded cognitive ability test and two UIT personality measures. These data permitted inferences about the magnitude and extent of malfeasant responding. The study objectives were accomplished by implementing two within‐subjects design studies ( Study 1 N=296; Study 2 N=318) in which test takers first completed the tests as job applicants (high‐stakes) or incumbents (low‐stakes) then as research participants (low‐stakes). For the speeded cognitive ability measure, the pattern of test score differences was more consonant with a psychometric practice effect than a malfeasance explanation. This result is likely due to the speeded nature of the test. And for the UIT personality measures, the pattern of higher high‐stakes scores compared with lower low‐stakes scores is similar to those reported for proctored tests in the extant literature. Thus, our results indicate that the use of a UIT administration does not uniquely threaten personality measures in terms of elevated scores under high‐stakes testing that are higher than those observed for proctored tests in the extant literature.     

Assessing entrepreneurial inclinations: Some approaches and empirical evidence

Interest in entrepreneurship is intense in many parts of the world and this has arisen because of the association between new venture creation and economic development. Entrepreneurship is a process that often leads to the creation of new enterprises but in this article the concept is broadened to include innovative and enterprising behaviour within existing organizations. While it is recognized that entrepreneurs and entrepreneurship are the products of various societal, organizational, and individual factors, this article focuses on the inherent personal traits of individuals that dispose them to engage in entrepreneurial acts. Some approaches to assessing the entrepreneurial personality are examined, but the principal focus is on pencil and paper measures of entrepreneurial attributes. Various instruments that purport to measure key entrepreneurial characteristics such as need for achievement, locus of control, and creative tendencies are considered and relevant empirical evidence is reported. A consideration of the appropriateness of the Durham University Business School's General Enterprising Tendency test as a composite instrument for assessing enterprising or entrepreneurial tendencies follows along with some statistical norms for this test, which should prove useful for practitioners and academics alike. Finally, some problems with trait theories of entrepreneurship are discussed.     

Bridging the gap between explicit and implicit measurement of personality: The questionnaire-based implicit association test

This study presents the questionnaire-based implicit association test (qIAT), a method that resembles the assessment procedures of self-report scales and allows an implicit assessment of constructs measured by such instruments. The qIAT measures the speed of association between ordinary questionnaires’ items (i.e., short statements rather than single words) and true versus false self-related sentences. Participants completed self-report measures of all Big-Five domains and the qIAT that measured extraversion. The qIAT implicit extraversion score showed good levels of internal consistency and it correlated with explicit extraversion but not with other explicit scales, thus supporting the convergent and discriminant validity of this measure. It also predicted a criterion behavior, and this prediction was incremental to self-report assessment of the same set of items. The qIAT opens the door for the indirect assessment of numerous psychological phenomena measured by existing self-report scales.     

Reliability of proxy response on mental health indices for aged, community-dwelling women

The correspondence between respondent and proxy response was evaluated on 4 mental health measures (Affect Balance Scale, Center for Epidemiological Studies Depression Scale, Mental Status Questionnaire, and Mini-Mental State Examination) with a sample of 538 respondent-proxy pairs. Results indicated that respondent and proxy responses were strongly associated, particularly for the cognitive measures. This association was found even for respondents classified as depressed or cognitively impaired. Although there was evidence of proxy bias, with proxies underrating affective status and overrating cognitive status, the magnitude of the bias proved small for all scales but the Mental Status Questionnaire. Examination of response comparability by proxy characteristics showed that choice of proxy affected agreement and bias. Implications of these findings for survey research are discussed.     

Factors Determining National Stereotypes

Summary

In order to test various explanations of the fact that perceived competence appears to correlate positively with altruism, Ss were given false feedback as to their competence on a “visual creativity” test and then asked to help with a second task, writing creative color names. Three groups of Ss who were told they were competent were given reduced cost, increased happiness, and increased responsibility as reasons for helping; the other three groups were given no explanations, but were told that their competence was high, or low, or given no information. The three explanation groups helped more than the other three groups, and the reduced cost group helped more than the other five. The three dependent measures of helping (percentage of helpful Ss, duration of help, and magnitude of help) proved differentially sensitive to treatment and sex differences. Only the latter two measures showed greater helping in the reduced cost group; only the magnitude measure showed significantly greater helping for males than females.     

Effects of psychotherapy with people who have been sexually assaulted: A meta-analysis

This paper presents the results of a meta-analysis of the treatment outcome studies of different types of psychotherapeutic approaches for sexual assault victims experiencing PTSD or rape trauma symptoms. There were 15 outcome studies identified for inclusion in the meta-analysis dating from 1988–2005, and these studies comprised 25 treatment conditions. Separate meta-analyses were conducted according to study design (independent samples and repeated measures), in keeping with meta-analytic conventions. The overall results for the two meta-analyses were highly consistent, and effect sizes were in the large range for independent samples (g = .91) and repeated measures treatments (g = .90). Effects were maintained at follow-up from 6–12 months after treatment. Studies represented diverse treatment approaches, and most treatments were effective in improving outcome according to symptom reduction. A number of moderating variables were examined. Better outcomes were achieved with individual therapy compared to group approaches. The use of semi-structured approaches and homework techniques were positively related to the magnitude of effect size.     

Personality Correlates of Confidence in One's Decisions

ABSTRACT Taylor and Brown (1988) hypothesized that certain illusions, such as unrealistic optimism, are predictably associated with positive affect, social skills, and intellectual functioning. To test this hypothesis, we obtained data from 162 students who first filled out a questionnaire containing dispositional measures of affect, social skills, and approaches to problem solving; in a second session they completed three tasks requiring difficult decisions, reporting their confidence in each decision. Accuracy of judgments was found to vary considerably from task to task, but confidence ratings showed a consistent pattern of individual differences. This result lent support to Taylor and Brown's hypothesis, as did other features of the data, most notably several small but significant Pearson r s between confidence ratings and dispositional variables. Removing the effects of accuracy from these r s reduced their magnitude very little; it yielded partial r s interpretable as evidence that illusory confidence is associated with personality traits which, in this case, load saliently on factors labeled ( a ) affective, and ( b ) cognitive/social.

Physical fitness differences between athletes and nonathletes: Do changes occur as a function of age and sex?

The main objectives were to determine (a) if physical fitness superiority of athletes over nonathletes increases as a function of age, and (b) if the magnitude of athlete-nonathlete fitness differences are the same in males as in females, and if these differences are consistent across ages. Approximately 3,000 students in grades 3, 7, and 11 (ages 9, 13, and 17 years) were tested on measures of static and explosive muscular strength, static and dynamic muscular endurance, cardiovascular endurance, and flexibility. MANOVA and follow-up univariate ANOVAs indicated that the higher the grade, the better the performance; males outperformed females on all measures except flexibility; and athletes were superior to nonathletes on all six test items. Furthermore, (a) there was no difference between athletes and nonathletes at grade 3, athletes were considerably better than nonathletes by grade 7, and the magnitude of the difference was virtually the same at grade 11, (b) the fitness superiority of athletes over nonathletes was essentially of the same magnitude for males as for females at each grade level.
