Sex differences in school-aged children with pervasive attention deficit hyperactivity disorder

This study investigated 54 children (37 boys and 17 girls) with cross-situational attention deficit hyperactivity disorder (ADHD) to determine whether there are sex differences in the expression of either the primary or secondary symptomatology of ADHD. Results indicated that the male and female ADHD groups were strikingly similar on all measures of primary (impulsivity, inattention, and overactivity) and secondary (learning problems, externalizing symptoms, internalizing symptoms, peer relationship difficulties, and self-perceptions) symptomatology included in this study. The lack of significant sex differences conflicts with prior reports in the literature, and these conflicting results are discussed in terms of differences in inclusion criteria. Implications for understanding the long-term outcome of ADHD in girls are also discussed.     

Identity and death anxiety

Sixty-three male Caucasian undergraduates were involved in a study examining possible relationships between death anxiety and Erikson's concept of ego identity. Participants were administered Marcia's Ego Identity Status Interview and Templar's Death Anxiety Scale (DAS) in counterbalanced order. A one-way analysis of variance revealed a significant main effect of ego identity status on DAS scores. One identity status, moratorium, was associated with significantly higher DAS scores than the other three statuses. Diffusion, foreclosure, and achievement statuses did not significantly differ on DAS scores.     

Inaccuracy of Affordance Judgments for Firefighters Wearing Personal Protective Equipment

In order to safely negotiate cluttered and dangerous environments, firefighters must efficiently and effectively make affordance judgments. Failure to do so could put them at risk for slips, trips, and falls, which are major causes of injuries for firefighters. We examined how well firefighters were able to perceive their obstacle crossing abilities while wearing firefighting protective equipment. Firefighters were asked to judge whether they could cross over, under, and through different obstacles that simulated idealized fireground situations. Perceptual judgment errors were found for each obstacle type, the largest occurring with an overestimation of ability to pass under an obstacle. Years of experience had a moderate positive correlation with absolute judgment error in the “over” and “under” obstacles. Overall, a general lack of awareness of their personal protective equipment for obstacle crossing ability was observed. A better understanding of how to reduce judgment error while wearing firefighter protective gear would likely decrease the risk of injuries on the fireground.     

Critical evaluation of Guilford's structure-of-intellect theory

The structure-of-intellect (SI) theory is evaluated within a framework of considerations of capitalization on chance. This empirical problem is placed in a larger perspective of concern for the general conceptual value of the theory in the study of human intelligence. The factor analytic support for the theory is found to be lacking in several notable respects. At best the research intended to support the model must be considered exploratory. But the model has provided a useful scheme for test construction and for indicating interesting hypotheses about qualities of intellect. Even in this context, however, there are several problems with the theory. The theory provides only a static taxonomy and thus affords very limited possibilities for understanding developmental issues.     

Scotopic sensitivity in coyotes (Canis latrans).

The absolute scotopic limen for light intensity was measured for three 10-mo-old female coyotes. The methodology was similar to that used by Blough in determining psychophysical thresholds in pigeons. Three coyotes were operantly conditioned to depress one of two foot treadles, left or right, depending on the condition of the stimulus light. Scotopic adaptation curves for each coyote were generated. Nonlinear regression curves were then fitted to the raw data. The mean scotopic thresholds did not differ significantly. However, time to the curves' asymptotes did differ significantly for one of the coyotes. The adaptation curves showed a distinct rod-cone "break," and retinal histology confirmed that the coyote has a duplex retina with a preponderance of rods. In addition, electroretinographic analysis showed the relative contributions of rods and cones at various light intensities and indicated a rod-cone break at approximately 15 min. Scotopic spectral sensitivity curves were also generated. The coyotes' scotopic visual threshold is exceeded by the natural illumination available under many nocturnal conditions. The results are discussed in relation to the ecology of the species.     

The effect of somaesthetic and acoustic stimuli on the threshold of fusion of paired light flashes in human subjects

The threshold of fusion of paired flashes of light was measured by determining the largest interval between two flashes of light at which they were reported as one and not as two flashes. When a weak electric shock to the skin was presented at the same time as the first flash, the threshold was increased compared to the threshold measured when the flashes were unaccompanied by a shock. As the interval between shock and first flash was increased up to 600 millisec, the effect diminished. A similar pattern of results was obtained using a click, instead of a shock as the additional stimulus. The effect on the two-flash threshold of varying click intensity was also studied. No retroactive effects of the shock on the two-flash threshold were observed.     

Familienfunktionalität und Therapieerfolg

Background

Even though it is a treatment standard of child psychotherapy to involve the parents, hardly any research has been carried out about the impact of family functioning on treatment outcome. Aims of the present study were to investigate the change in and the prognostic power of family functioning on treatment outcome of short-term psychodynamic psychotherapy in children and adolescents.

Patients and methods

The sample consisted of 54 children and adolescents undergoing outpatient short-term psychodynamic psychotherapy. To assess family functioning, their parents were asked to complete the Family Assessment Measure (FAM).

Results

Patients from families with high levels of functioning in task accomplishment, communication and affective expression were more often treated successfully. Improvement in levels of functioning in role performance, emotionality and control were only found in the group of successfully treated patients.

Conclusion

Family functioning is a decisive factor in the differential indication of psychotherapeutic treatment in children and adolescents.     

Daily Reports of Stress,Mood, and Physical Health in Middle Childhood

Most empirical work examining stress in children focuses on major life events, like divorce of parents, while fewer studies consider the role of daily stressors, or the routine challenges of day-to-day living. Existing work on children’s daily stress is lacking such that it primarily: (1) focuses on children who are ill, disabled, or who face significant environmental risks, (2) relies on retrospective reports, (3) relies on parent or teacher reports of stressors experienced by children, or (4) does not comprehensively examine the role of stress on mood and health. In the current study, we explored daily experiences of stress, mood, and physical health symptoms across five consecutive days in 25 children between 8 and 10 years old. Results showed that children reported a variety of types of stressors, and that more stressors were reported by older children, girls, and on weekdays compared to weekends. Daily reports of stress were linked to same day reports of physical health symptoms but not mood, however the presence of both negative mood and daily stress was associated with even more same day health symptoms. This study extends prior work by examining children’s stress at the daily level as well as relying on children’s self-reports of their stress, mood, and physical health symptoms.
