The influence of parenting stress and child behavior problems on parental estimates of expressive and receptive language development

This study examined the relative contributions of parental reports of child-related and parent-related stress to their estimates of expressive and receptive language skills on the Minnesota Child Development Inventory in 152 children referred to a communicative disorders clinic. Correlational analysis showed moderately high agreement between parental estimates and objective measures of expressive and receptive language ability. Multiple-regression analyses revealed that independent measures of language acquisition accounted for the greatest amount of variance in parental estimates of expressive and receptive language skills. Stressful child behavior accounted for a small but statistically significant proportion of the variance in estimates of expressive and receptive language skills. Parental stress, in contrast, did not contribute significantly to language estimates. These findings suggest that parents are able to formulate estimates of language development which are relatively independent of personal or child-related stressors.     

The Role of Mothers and Fathers

The development of personality characteristics appears to differ by sex of child and role of parent, with interpersonal concerns tending to characterize mothers and instrumental concerns describing fathers. Using a semi-structured interview protocol and paper-and-pencil questionnaires, we examined the effects of parenting, as reported by middle-class high school senior boys and girls, on the development of two aspects of personality. Ego development and self-esteem both have demonstrated sex differences, with girls displaying more advanced ego development and boys displaying higher self-esteem. We expected that mothers, because of their greater interpersonal orientation, would influence the development of ego development more than would fathers, and that, based on past findings, the opposite-sex parent would exert the primary influence on self-esteem. While ego development was found to relate to more encouraging, warmer mothering in boys, it related weakly to mothering in girls. Boys and girls who perceived their cross-sex parent to be warm and supportive were found to have higher self-esteem.     

Program report: “time-in”: A two-year project for the reduction of severe maladaptive behaviors in a center for persons with developmental disabilities

The results of a two-year project designed to organize a unit for 18 developmentally disabled clients with severe behavior disorders (primarily aggression) were presented. Providing tightly organized structure and focusing on appropriate resident behavior resulted in substantial gains. Noted changes included significant decreases in aggression, total number of target behaviors, required uses of restrictive procedures, and residents' injuries. Decreases were also noted in staff injuries and turnover. Subjectively, the unit became a better place to work and live. Difficulties encountered with developing, maintaining, and generalizing the project were discussed.     

The distribution of infant attention during object examination

The distribution of attention during toy play was studied in 6‐, 9‐ and 12‐month‐old infants. Heart rate and behavior measures of attention were collected as the infants interacted with objects. There was a large deceleration of heart rate at the beginning of behaviorally defined focused attention, but little heart rate change for looks that only had behaviorally defined casual attention. Heart‐rate‐defined sustained attention occurred more frequently at the transition from the first instance of casual attention within a look to focused attention and during the cycling between subsequent epochs of casual and focused attention. These results show that heart rate and behavioral measures of attention are closely related in young infants at the beginning and end of object interaction but are inconsistently related within a single look at an object.     

A planar and a volumetric test for stereoanomaly

Stereoanomaly is the failure to see differences in depth when the viewer is presented with stimuli having different magnitudes of stereoscopic disparity. In the absence of eye movements, everyone suffers from stereoanomaly for extremely large disparities. Typically, such disparities are seen at the same depth as monocular stimuli. However, about 30%, of the population exhibit some form of stereoanomaly even for very small disparities, provided eye movements are avoided. In some cases, the sign of the disparity will be confused, and the perceived depth will be incorrectly seen as 'behind' rather than 'in front of' the fixation point, for example. Because anomalies provide useful information about perceptual mechanisms, tests that measure and quantify the extent of a blindness are important investigative tools for research. Here we offer two easy-to-administer tests for stereoanomaly. The first test is based on depth judgments of two bars relative to a fixation point. The second test involves judgments of volumetric stimuli, seen stereoscopically. In each case, subjects indicate depth by setting a rectangle (with fixed base) to match the perceived depth. Although both tests are correlated, some differences in stereo processing are seen, depending upon whether or not the stimuli are presented near the point of fixation.     

Localizing cortical sources of event-related potentials in infants' covert orienting

This study used cortical source analysis to locate potential cortical sources of event-related potentials (ERPs) during covert orienting in infants aged 14 and 20 weeks. The infants were tested in a spatial cueing procedure. The reaction time to localize the target showed response facilitation for valid trials relative to invalid or neutral trials. High-density EEG (126 channels) was recorded during the task, and independent component analysis and equivalent current dipole analysis was used to estimate the cortical sources of the EEG during the task. There was a larger P1 ERP component on the valid trials than the other trials (P1 validity effect). The cortical source analysis suggested that this occurred due to activity in Brodmann's areas 18 and 19. A presaccadic ERP component occurred over the frontal scalp areas (-65 ms) and was larger to a target in a cued location than in uncued locations. A potential cortical source for this ERP component was the superior frontal gyrus on the inferior portion of the prefrontal cortex. Increases from 14 to 20 weeks in amplitude of the P1 validity effect and the presaccadic ERP could be modeled by an increase in activation in the corresponding cortical areas.     

Lack of degradation in visuospatial perception of line orientation after one night of sleep loss

Sleep deprivation impairs a variety of cognitive abilities including vigilance, attention, and executive function. Although sleep loss has been shown to impair tasks requiring visual attention and spatial perception, it is not clear whether these deficits are exclusively a function of reduced attention and vigilance or if there are also alterations in visuospatial perception. Visuospatial perception and sustained vigilance performance were therefore examined in 54 healthy volunteers at rested baseline and again after one night of sleep deprivation using the Judgment of Line Orientation Test and a computerized test of psychomotor vigilance. Whereas psychomotor vigilance declined significantly from baseline to sleep-deprived testing, scores on the Judgment of Line Orientation did not change significantly. Results suggest that documented performance deficits associated with sleep loss are unlikely to be the result of dysfunction within systems of the brain responsible for simple visuospatial perception and processing of line angles.     

How beneficial is cognitive behaviour therapy in the treatment of atopic dermatitis? A single-case study

A single-case design was used to examine the benefits of cognitive behaviour therapy (CBT) in the treatment of two patients with atopic dermatitis (AD). Improvements were indicated for both cases in global outcome measures, with reductions in anxiety, depression and stigmatization beliefs and improvements in quality of life. Self-rated AD severity remained relatively stable across treatment time. For both cases, treatment gains were particularly evident in terms of reducing avoidance behaviours. The findings were discussed in relation to the need for CBT as an adjunct treatment for patients with AD and its potential role in improving psychological functioning.     

Sibling Maltreatment: The Forgotten Abuse

Great advances have been made in the study of family violence in the past 30 years. However, sibling abuse and its prevalence in the family have largely been overlooked. In this article, the major issues associated with sibling maltreatment are highlighted, and strategies for helping the victims and perpetrators of sibling abuse and their families are described.
