Does socioeconomic status explain the relationship between admissions tests and post-secondary academic performance?

Critics of educational admissions tests assert that tests measure nothing more than socioeconomic status (SES) and that their apparent validity in predicting academic performance is an artifact of SES. The authors examined multiple large data sets containing data on admissions and related tests, SES, and grades showing that (a) SES is related to test scores (r = .42 among the population of SAT takers), (b) test scores are predictive of academic performance, and (c) statistically controlling for SES reduces the estimated test?grade correlation from r = .47 to r = .44. Thus, the vast majority of the test?academic performance relationship was independent of SES: The authors concluded that the test?grade relationship is not an artifact of common influences of SES on both test scores and grades.

Knowing who’s boss: Implicit perceptions of status from the nonverbal expression of pride.

Evolutionary theory suggests that the universal recognition of nonverbal expressions of emotions functions to enhance fitness. Specifically, emotion expressions may send survival-relevant messages to other social group members, who have the capacity to automatically interpret these signals. In the present research, we used 3 different implicit association methodologies to test whether the nonverbal expression of pride sends a functional, automatically perceived signal about a social group member’s increased social status. Results suggest that the pride expression strongly signals high status, and this association cannot be accounted for by positive valence or artifacts of the expression such as expanded size due to outstretched arms. These findings suggest that the pride expression may function to uniquely communicate the high status of those who show it. Discussion focuses on the implications of these findings for social functions of emotion expressions and the automatic communication of status.

Campbell’s and Rubin’s perspectives on causal inference.

Donald Campbell’s approach to causal inference (D. T. Campbell, 1957; W. R. Shadish, T. D. Cook, & D. T. Campbell, 2002) is widely used in psychology and education, whereas Donald Rubin’s causal model (P. W. Holland, 1986; D. B. Rubin, 1974, 2005) is widely used in economics, statistics, medicine, and public health. Campbell’s approach focuses on the identification of threats to validity and the inclusion of design features that may prevent those threats from occurring or render them implausible. Rubin’s approach focuses on the precise specification of both the possible outcomes for each participant and assumptions that are mathematically sufficient to estimate the causal effect. In this article, the authors compare the perspectives provided by the 2 approaches on randomized experiments, broken randomized experiments in which treatment nonadherence or attrition occurs, and observational studies in which participants are assigned to treatments on an unknown basis. The authors highlight dimensions on which the 2 approaches have different emphases, including the roles of constructs versus operations, threats to validity versus assumptions, methods of addressing threats to internal validity and violations of assumptions, direction versus magnitude of causal effects, role of measurement, and causal generalization. The authors conclude that investigators can benefit from drawing on the strengths of both approaches in designing research. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Editor’s choices.

Reviews the books, Mind regained by Edward Pols (see record 1998-06466-000); Manifesto of a passionate moderate by Susan Haack (1998); and Mind, meaning and mental disorder: The nature of causal explanation in psychology and psychiatry by Derek Bolton and Jonathan Hill (see record 1996-98296-000). In different but equally compelling ways, these three books address central problems in philosophical psychology and offer telling replies to more complacent perspectives on the nature of mind and mental life. The first two of the volumes are by philosophers, the third by authors trained in clinical psychology and psychiatry. In different ways, each of the volumes is at war with simplistic conceptions of explanation; each is also careful to distinguish between the correctives needed and a lapse into relativistic and ultimately skeptical positions on the nature of knowledge itself. All three of these volumes would serve as useful, even essential, texts in advanced courses in theory and philosophy of psychology, philosophy of social science, philosophy of mind. But so would they serve in interesting ways the larger aims of courses in Personality and Abnormal Psychology. Together, these books present encouraging reminders of the importance of conceptual analysis to the development and refinement of Psychology.

Reviews the books, Emotion and peace of mind: From stoic agitation to Christian temptation by Richard Sorabji (2000) and Other minds by Anita Avramides (2001). The two works considered here are deeply serious and composed by scholars who have executed their projects with undeviating integrity. In Emotion and Peace of Mind, based on his Gifford Lectures, Richard Sorabji moves the reader through a veritable course of study on a subject as notoriously protean as it is central to the lived life. The twenty-six chapters range over whole realms of thought on the subject of emotion, beginning with ancient philosophy and reaching the research and theory advanced right now in that congeries of specialties dubbed the brain sciences. Between the covers of this truly estimable work one meets not just the subtle and instructive thought of Seneca and Augustine, Iamblichlus and Epictetus, but insightful commentaries on the work of Damasio, Le Doux, Maclean and others. In all, Emotion and Peace of Mind is a benchmark- volume, an outstanding contribution to the philosophy and psychology of emotion; surely a required work for anyone prepared to approach the subject with the seriousness it demands. The second book of this review, Other Minds, is a work of philosophical rigor and originality, composed by an Oxford tutor who has skillfully shaped other minds with the sharp and sharpening instrument of conceptual analysis. Do computers have minds? Do animals have minds? Are there minds other than my own? And if I know of my own mind in that most basic first-person sense, then clearly there is no other mind that I can thus know. If there is something epistemologically amiss about first-person achievements, then there is surely something suspect about claims to the effect that I know of my mind. If there is nothing less than a required first-person account of minds, then there is something epistemologically suspect about any statement of any other mind.

To act or not to act, that’s the problem: Primarily inhibition difficulties in adult ADHD.

Forty-nine carefully diagnosed adults with persistent attention deficit/hyperactivity disorder (ADHD), who had never been medicated for their ADHD, were compared with 49 normal control adults matched for age and gender on a large battery of tests in five domains of executive functioning (inhibition, fluency, planning, working memory, and set shifting) and several other neuropsychological functions to control for nonexecutive test demands. After stringent controls for nonexecutive function demands and IQ, adults with ADHD showed problems in inhibition and set shifting but not in any of the other executive functioning domains tested. We argue that adult ADHD may be mainly a disorder of inhibition. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Taylor’s Slope Stability Charts Revisited

Two design charts for computing the safety factor of soil slopes are presented here. The first one is for an undrained (?u = 0) soil slope, similar to the one proposed by Taylor, but with significant differences. Taylor’s work is based on three types of failure circles: toe circle, slope circle, and midpoint circle. It appears that there can also be compound circles that are made of two circular arcs separated by a straight line at the interface with the stiff stratum. These are incorporated in the proposed design chart. The second chart is for drained (c′-?′) soil slope that enables the users to compute the safety factor of the slope without any iterative procedures that are required with the Taylor’s chart. In c′-?′ soils, Taylor assumed that the failure occurs along toe circles. The analysis presented herein shows that when the slope is very shallow, it is possible to have midpoint circles. Both charts are quite simple and straightforward to use in engineering analysis of homogeneous slopes. Numerical examples are presented to illustrate the use of the two design charts.     

Linking marital conflict and children’s adjustment: The role of young children’s perceptions.

Young children’s (n = 96) perceptions and appraisals of their parents’ marital conflict were evaluated at age 5 and again at age 6. Concurrent reports of marital conflict by each parent and teachers’ reports of children’s classroom adjustment served as criteria against which to evaluate the validity of young children’s perceptions. Children’s perceptions of their parents’ marital relationship were significantly correlated with spouses’ reports at ages 5 and 6, as well as correlated with teacher reports of internalizing and externalizing problems. Consistent with the cognitive–contextual theory, children’s tendency to blame themselves for their parents’ conflict partially mediated the link between marital conflict and children’s internalizing symptoms. In contrast, children’s reports that they become involved in their parents’ conflict partially mediated the effect of marital conflict on externalizing problems.

Clients’ secret keeping and the working alliance in adult outpatient therapy.

This research investigated the relations among clients’ keeping relevant secrets in therapy, the working alliance, and symptom change. Clients (N = 83) in outpatient therapy and their therapists (N = 22) at a mental health hospital completed confidential surveys after a session of ongoing therapy. The clients who reported keeping a relevant secret (27.7%) scored significantly lower on the Working Alliance Inventory (WAI) than did clients who said that they were not, even when the analyses controlled for clients’ social desirability scores and for therapist effects. Therapists of these clients also reported a weaker working alliance, even though the therapists typically did not know that the clients were keeping a relevant secret. However, keeping a relevant secret was not related to symptom change. The findings support the long-standing belief that secret keeping in therapy either hurts the therapeutic relationship or happens when the relationship is relatively weak.

The development, evolution, and status of Holland’s theory of vocational personalities: Reflections and future directions for counseling psychology.

This article celebrates the 50th anniversary of the introduction of John L. Holland’s (1959) theory of vocational personalities and work environments by describing the theory’s development and evolution, its instrumentation, and its current status. Hallmarks of Holland’s theory are its empirical testability and its user-friendliness. By constructing measures for operationalizing the theory’s constructs, Holland and his colleagues helped ensure that the theory could be implemented in practice on a widespread basis. Empirical data offer considerable support for the existence of Holland’s RIASEC types and their ordering among persons and environments. Although Holland’s congruence hypotheses have received empirical support, congruence appears to have modest predictive power. Mixed support exists for Holland’s hypotheses involving the secondary constructs of differentiation, consistency, and vocational identity. Evidence of the continued impact of Holland’s theory on the field of counseling psychology, particularly in the area of interest assessment, can be seen from its frequent implementation in practice and its use by scholars. Ideas for future research and practice using Holland’s theory are suggested. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Do cardiovascular risk factors explain the relation between socioeconomic status, risk of all-cause mortality, cardiovascular mortality, and acute myocardial infarction?

Much remains to be understood about how low socioeconomic status (SES) increases cardiovascular disease and mortality risk. Data from the Kuopio Ischemic Heart Disease Risk Factor Study (1984-1993) were used to estimate the associations between acute myocardial infarction and income, all-cause mortality, and cardiovascular mortality in a population-based sample of 2,272 Finnish men, with adjustment for 23 biologic, behavioral, psychologic, and social risk factors. Compared with the highest income quintile, those in the bottom quintile had age-adjusted relative hazards of 3.14 (95% confidence interval (CI) 1.77-5.56), 2.66 (95% CI 1.25-5.66), and 4.34 (95% CI 1.95-9.66) for all-cause mortality, cardiovascular mortality, and AMI, respectively. After adjustment for risk factors, the relative hazards for the same comparisons were 1.32 (95% CI 0.70-2.49), 0.70 (95% CI 0.29-1.69), and 2.83 (95% CI 1.14-7.00). In the lowest income quintile, adjustment for risk factors reduced the excess relative risk of all-cause mortality by 85%, that of cardiovascular mortality by 118%, and that of acute myocardial infarction by 45%. These data show how the association between SES and cardiovascular mortality and all-cause mortality is mediated by known risk factor pathways, but full "explanations" for these associations will need to encompass why these biologic, behavioral, psychologic, and social risk factors are differentially distributed by SES.
