Intonation does aid serial recall after all

Psychonomic Bulletin & Review - A sequence of spoken digits is easier to recall if the digits are grouped into smaller chunks (e.g., through the insertion of pauses). It has been claimed that...

The perception of a face is no more than the sum of its parts

When you see a person's face, how do you go about combining his or her facial features to make a decision about who that person is? Most current theories of face perception assert that the ability to recognize a human face is not simply the result of an independent analysis of individual features, but instead involves a holistic coding of the relationships among features. This coding is thought to enhance people's ability to recognize a face beyond what would be expected if each feature were shown in isolation. In the study reported here, we explicitly tested this idea by comparing human performance on facial-feature integration with that of an optimal Bayesian integrator. Contrary to the predictions of most current notions of face perception, our findings showed that human observers integrate facial features in a manner that is no better than would be predicted by their ability to use each individual feature when shown in isolation. That is, a face is perceived no better than the sum of its individual parts.

Executive Attention: An Alternative Perspective on General Mental Ability,Performance, and Subgroup Differences

The validity‐adverse impact tradeoff associated with the relationships among general mental ability (GMA), ethnicity, and employee performance represents one of the most pressing concerns in organizational staffing. We conducted 4 studies with 273 bank employees and 197 university students designed to assess the extent to which executive attention (EA) and GMA predict simulation performance and supervisory ratings of performance. We also assess the extent to which measures of EA and GMA are associated with subgroup differences. Results indicate that, like GMA, EA positively predicts managerial simulation and supervisory ratings of performance. In addition, although reaching statistical significance in only 1 of our 4 studies, EA was generally associated with smaller subgroup differences than GMA, and meta‐analysis across our samples supports this reduced subgroup difference. Moreover, advantages of EA tend to increase as studies move from the laboratory with undergraduate students to a concurrent validation organizational setting with employees. We discuss implications for a theory‐based view of cognitive ability in employee selection and implications for managerial practice.     

Effect of a kickboxing match on salivary cortisol and immunoglobulin A

The hypothesis that salivary cortisol would increase and salivary immunoglobulin A (IgA) decrease after a kickboxing match was tested among 20 male athletes. Saliva samples collected before and after the match were analyzed. Salivary cortisol and salivary IgA concentrations (absolute concentration, salivary IgAabs) and the secretion rate of IgA (salivary IgArate) were measured by enzyme-linked immunosorbent assay. A Wilcoxon test for paired samples showed significant increases in salivary cortisol from pre- to postmatch. No significant changes were observed in salivary IgAabs or secretory IgArate and saliva flow rate. This study indicates that a kickboxing match might increase salivary concentration and thereafter it could be considered a significant source of exercise-related stress. On the other hand, the effect of a kickboxing match on mucosal immunity seems not to be relevant.     

HARKing's Threat to Organizational Research: Evidence From Primary and Meta‐Analytic Sources

We assessed presumed consequences of hypothesizing after results are known (HARKing) by contrasting hypothesized versus nonhypothesized effect sizes among 10 common relations in organizational behavior, human resource management, and industrial and organizational psychology research. In Study 1, we analyzed 247 correlations representing 9 relations with individual performance in 136 articles published in Journal of Applied Psychology and Personnel Psychology and provide evidence that correlations are significantly larger when hypothesized compared to nonhypothesized. In Study 2, we analyzed 281 effect sizes from a meta‐analysis on the job satisfaction–job performance relation and provide evidence that correlations are significantly larger when hypothesized compared to nonhypothesized. In addition, in Study 2, we documented that hypothesized variable pairs are more likely to be mentioned in article titles or abstracts. We also ruled out 13 alternative explanations to the presumed HARKing effect pertaining to methodological (e.g., unreliability, publication year, research setting, research design, measure contextualization, publication source) and substantive (e.g., predictor–performance pair, performance measure, satisfaction measure, occupation, job/task complexity) issues. Our results suggest that HARKing seems to pose a threat to research results, substantive conclusions, and practical applications. We offer recommended solutions to the HARKing threat.     

Emotional intelligence and relationship quality among couples

To assess whether emotional intelligence (EI) is related to self‐assessed relationship quality, an ability test of EI and measures of relationship quality were administered to 86 heterosexual couples in a university setting. Results indicated that female partners were significantly higher in EI than male partners and that EI scores were uncorrelated within couples. Two 2 × 2 multiple analyses of variance (performed separately for positive and negative outcomes) assessed how relationship quality measures differed across four different types of couples (high‐EI female/high‐EI male, low‐EI female/low‐EI male, etc.). As predicted, couples with both partners low on EI tended to have the lowest scores on depth, support, and positive relationship quality and the highest scores on conflict and negative relationship quality. Counter to our hypotheses, couples with both partners high on EI did not consistently have higher scores on positive outcomes and lower scores on negative outcomes than couples with one high‐EI partner.     

Vegetative state: efforts to curb misdiagnosis

Media reports on the case of Rom Houben have constituted a new reminder of the risks of misdiagnosis with cases with apparent vegetative state, particularly when following the clinical consensus of the care team as diagnostic criterion. Systematic use of behavioral and non-behavioral assessment strategies (e.g., behavioral scales, event-related potentials, and neuro-imaging) may help reduce the aforementioned risks. A new learning assessment strategy could also be considered part of the assessment to extend the evaluation process. Signs of learning might be viewed as forms of concrete knowledge representing a basic level of non-reflective consciousness.
