The Incremental Validity of Honesty–Humility Over Cognitive Ability and the Big Five Personality Traits

The present study examines the incremental validity of Honesty–Humility (H-H), a measure of the tendency to be fair and genuine in dealing with others, for supervisory ratings of job performance (including both task and contextual performance) over cognitive ability and the Big Five personality traits. Specifically, we explore the incremental validity of H-H in predicting contextual performance. Results based on 217 South Korean military officer candidates are consistent with previous conclusions that Conscientiousness is the strongest predictor of contextual performance and that cognitive ability is the strongest predictor of task performance. More important, our results reveal that H-H offers moderate incremental validity for contextual performance but no incremental validity for task performance over the effects of cognitive ability and the Big Five personality traits.     

Evaluation of the Spiritual Well-Being Scale in a Sample of Korean Adults

This study explored the psychometric qualities and construct validity of the Spiritual Well-Being Scale (SWBS; Ellison in J Psychol Theol 11:330–340, 1983) using a sample of 470 Korean adults. Two factor analyses, exploratory factor analysis and confirmatory factor analysis, were conducted in order to test the validity of the SWBS. The results of the factor analyses supported the original two-dimensional structure of the SWBS—religious well-being (RWB) and existential well-being (EWB) with method effects associated with negatively worded items. By controlling for method effects, the evaluation of the two-factor structure of SWBS is confirmed with clarity. Further, the differential pattern and magnitude of correlations between the SWB subscales and the religious and psychological variables suggested that two factors of the SWBS were valid for Protestant, Catholic, and religiously unaffiliated groups except Buddhists. The Protestant group scored higher in RWB compared to the Buddhist, Catholic, and unaffiliated groups. The Protestant group scored higher in EWB compared to the unaffiliated groups. Future studies may need to include more Buddhist samples to gain solid evidence for validity of the SWBS on a non-Western religious tradition.     

Anxiety and Depression Symptoms in Children with Asperger Syndrome Compared with Attention-Deficit/Hyperactivity Disorder and Depressive Disorder

The objective of this study was to examine (a) anxiety and depression symptoms in children with Asperger syndrome (AS) compared to children with attention-deficit/hyperactivity disorder (ADHD) and children with depressive disorder; (b) parental anxiety and depressive symptoms in the three groups; and (c) the association between the anxiety and depression symptoms of children and their parents. The emotional and behavioral problems of 56 children with AS (48 boys, 8 girls, mean age, 9.39 ± 2.01 years) were compared with 56 ADHD children and 56 depressive disorder children, matched for age and sex. Their parents’ anxiety and depression symptoms were also compared. Trait-anxiety and internalizing problems in AS children were higher than those in ADHD children and as high as those in depressive disorder children (F = 8.83, p < 0.001 and F = 8.21, p < 0.001). Parents’ anxiety and depression symptoms did not differ among the three groups, but correlations between maternal anxiety and depression and children’s emotional and behavioral problems were most prominent in the AS group. We suggest that the assessment and treatment of children with AS should involve detailed assessment, possible concomitant treatment for comorbid anxiety and depression, and parental education about the effect of parental emotional states on children.     

Parent Grief 1–13 Months After Death in Neonatal and Pediatric Intensive Care Units

Objective. Describe changes in mothers’ and fathers’ grief from 1 to 13 months after infant or child neonatal or pediatric intensive care unit death and identify factors related to their grief.

Methods. Mothers (n = 130) and fathers (n = 52) of 140 children (newborn–18 years) completed the Hogan Grief Reaction Checklist at 1, 3, 6, and 13 months postdeath.

Results. Grief decreased from 3 to 13 months for mothers and from 3 to 6 months for fathers. Grief was more intense for mothers of deceased adolescents and mothers whose children were declared brain dead.

Conclusion. Mothers’ and fathers’ grief intensity may not coincide, resulting in different needs during the 13 months after infant or child death.     

Biochemistry of nervous dogs

Previous behavioral studies on a nervous strain of pointer dogs have demonstrated genetic as well as environmental components in the nervous trait. Behaviorally these animals are extremely hypervigilant, with an apparent low threshold to fear and show strong avoidance of humans. In addition, the nervous E strain dogs show an unusually high degree of sensitivity to the mange mite. These observations led to the initiation of studies to determine whether differences exist between the normal A strain and the E strain of dogs at the biochemical level. Although a number of biochemical parameters examined have shown no statistically significant difference between the two strains, the modification of serum creatine phosphokinase (CPK) activity in response to various types of stress does differ as a function of strain—the nervous dogs being less, not more, responsive than the healthy dogs. When not specifically subjected to stress the serum CPK levels in both strains were highly related to age. Significant differences between strains also have been demonstrated in the cerebrospinal fluid acetyl cholinesterase activity levels in older animals. Tryptophan loading experiments, conducted in the presence and absence of the monoamine oxidase inhibitor, tranylcypromine, resulted in no readily observable behavioral modification of either strain and the response of the cerebrospinal fluid 5-hydroxyindoleacetic acid levels was similar for the two strains.     

Effect of person and environment on heart rates in two strains of pointer dogs

Several recent studies have shown that there is a general and marked canine cardiac response to humans and to petting from humans. Additional investigations have suggested that one of the major determinants of such responding is genetic. Some studies have indicated that such a response does not occur in nervous, short-haired pointer dogs. Evidence presented in this study indicates that a heart rate response to person and petting does occur in both the nervous as well as the normal pointer dog, but only when the animal is unrestrained. When placed in a restraining harness, only normal dogs showed a heart rate response to person and the characteristic bradycardia upon petting. Moreover, in this and two other separate experiments in which tones (CS’s) were given, it was observed in both normal and nervous strains that mean baseline heart rates were as much as 40 beats per minute lower in the restrained situation than in the unrestrained situation. These experiments measured retention of cardiac response to aversive conditional signals, since most dogs (9 of 12) had received both tones and shock in a bar jumping-shock avoidance experiment one year previously. However, heart rates varied inconsistently in both magnitude and direction of change upon CS showing little or no retention. These findings clarify ambiguity in previous reports and again show that the restraining conditions in an experiment can constitute a serious stress for the animal and be a major factor in the results.     

An inexpensive activity measuring device for small animals

A satisfactory device for measuring activity of rats or other small animals has been a difficult problem. Several types of instruments have given incorrect measurements or are prohibitively expensive. Photocells give the same readout to a bobbing head as for a walk over a considerable distance requiring only the interruption of a light beam. Other devices require rotation of wheels or complex integrating circuits which must be replicated or scanned and recorded for simultaneous activity measurement of many animals. The device reported here utilizes the tilting of balanced cages to actuate a single microswitch coupled to an impulse counter for each cage. The system has functioned well for several years.     

Eccentricity biases of object categories are evident in visual working memory

In high-order object areas, face-selective areas prefer centrally presented stimuli, whereas building-selective areas prefer peripherally presented stimuli (Levy et al., 2001). We investigated whether this eccentricity bias was also evident in visual working memory. In Experiment 1, we found that working memory performance for faces decreased towards the periphery while the performance for buildings remained unchanged across different eccentricities. To rule out the possibility that lower level features influence these results, we manipulated the spatial frequency of faces and buildings (Experiment 2) and the spatial layout information of the buildings (Experiment 3). In both of the experiments, we replicated the results of Experiment 1, even when these lower level features of stimuli were controlled. Consistent with previous findings, the current results suggest that each object category is processed in a different manner depending on the eccentricity. This eccentricity bias is likely the result of how the high-order object areas represent different object categories.     

Integrating personality,context, relationship,and emotion type into a model of display rules

This research sets out to examine individual variations in perceptions of display rules. Based upon Mischel and Shoda’s [Mischel, W., & Shoda, Y. (1995). A cognitive-affective system theory of personality: Reconceptualizing situations, dispositions, dynamics, and invariance in personality structure. Psychological Review, 102, 246–268.] model of the Cognitive-Affective Personality System (CAPS), we proposed that extraversion and neuroticism would serve to explain within-cultural individual differences and within-individual differences in endorsement of display rules. To test this hypothesis, participants reported the expressivity level of the display rule they endorsed by responding to the revised version of the Display Rule Assessment Inventory. Multi-level analyses showed that compared to those of introverts, the display rules of extraverts tended to be more suppressive when the relationship was distant rather than close. Extraversion also enhanced a neurotic’s degree of suppression in public compared to private situations. Processes describing how personality interacts with situations in personalizing display rules were offered in light of the CAPS model to account for these interactions between personality and situation in the operation of display rules for emotional expression.
