Neurocognitive Sequelae of Pediatric Sickle Cell Disease: A Review of the Literature

This literature review summarizes all studies relating neuropsychological performance to neuroimaging findings in pediatric sickle cell disease (N=28; published 1991–2005). Although inconsistencies exist within and across domains, deficits in intelligence (IQ), attention and executive functions, memory, language, visuomotor abilities, and academic achievement have been identified. Overall neurocognitive compromise was revealed to be related to the level of neurological injury and the location of silent infarct. Attentional and executive dysfunction is prevalent and related to frontal lobe abnormalities.     

Cognitive Behavior Therapy With Body Image Exposure for Bulimia Nervosa: A Case Example

Cognitive behavior therapy (CBT) is an effective treatment for bulimia nervosa (BN). However, among patients with BN, symptom improvement is more pronounced for behavioral eating symptoms (i.e., bingeing and purging) than for body image disturbance, and the persistence of body image disturbance is associated with relapse. The need for more effective body image interventions led to the development of mirror exposure, which focuses on encouraging patients to view themselves in a holistic, nonjudgmental, mindful fashion. Behavioral manifestations of body image disturbance—body checking and avoidance—are also targeted in order to reduce and eliminate such behaviors and their associated preoccupation and distress. A preliminary trial of Body Image Exposure has shown promise, but it has not yet been tested in the context of CBT for BN. The case of “Sara” illustrates the application of this targeted treatment for body image disturbance. Central clinical issues around the perceptual, cognitive, and behavioral components of body image are delineated as they arose in treatment, as are issues of motivation and compliance. Treatment was associated with improvement in eating symptoms, body image, and mood.     

Faculty Perceptions about Tenure at Private Christian Liberal Arts Colleges

This study investigates faculty perceptions of tenure at 38 institutions of the Council for Christian Colleges and Universities (CCCU) with a sample of 988 faculty with tenure, 734 on a tenure track, 427 who are not on a tenure track, and 411 from institutions without tenure. Major findings that emerges are (1) more male have earned tenure; (2) the majority of tenures faculty agreed that the criteria for advancement and promotion are clear; (3) most disagree that tenure is an outmoded concept; (4) faculty with tenure are more likely to believe that tenure attracts the best minds; (5) CCCU faculty working toward tenure report lower levels of extensive stress than the national sample.     

Caregiver models of self and others, coping, and depression: predictors of depression in children with chronic pain.

In a sample of 59 chronically ill pediatric patients and their maternal caregivers, both child-reported pain and caregiver-reported depression predicted child-reported depression. Results further suggested that the association between pain and depression in children is ameliorated by caregiver coping strategies and that how caregivers cope is a function of their attachment-related representations of the self and others. Caregivers with a negative model of the self were more depressed. and those with a negative model of others were more prone to use avoidant coping strategies, and, in turn, to be more depressed. However, the extent to which caregivers with negative models of self used more avoidant and less approach coping appeared to depend on whether they perceived that others were likely to respond to their needs.     

Extending the activity restriction model of depressed affect: evidence from a sample of breast cancer patients.

Survey data from 95 women with Stage 1 (n = 36), Stage 2 (n = 49), or Stage 3 (n = 10) breast cancer both confirm and extend prior research indicating that restriction of normal activities is an important factor in depressed affect. Illness severity was directly related to more restricted routine activities, and more activity restriction was associated with higher public self-consciousness and less social support. Beyond the effects of age, self-consciousness, illness severity, and social support, activity restriction explained significant additional variance in symptoms of depression. Moreover, activity restriction mediated the impact of pain, public self-consciousness, and social support on depressed affect, which implies that these factors foster symptoms of depression by disrupting normal activities.     

The Aramaic Documents in Ezra Revisited

In recent years there has been a significant shift in scholarlyopinion concerning the Aramaic documents included in the bookof Ezra; whereas 25 years ago their historical authenticitywas widely accepted, more recent studies have claimed that theywere fabricated by the biblical author. In the present article,the reasons for this change of opinion are examined, and itis concluded that in most cases the decision about authenticityis taken on the basis of extraneous considerations relatingto the composition of the book or the course of history whichit purports to relate. The arguments advanced in relation tothe documents themselves are the same as those which were commona century ago, and to that extent may be answered in the sameway as before. In particular, insufficient attention has beenpaid to the fact that from a literary point of view it is thedocuments which determine the shape and wording of the narrative,not vice versa. It is therefore most natural to conclude thatthey existed already prior to the composition of the book. Onlyin two areas are there new data to be considered—languageand the epistolary form of the documents. An examination ofthe salient evidence concludes that it is far from univocaland that it cannot, therefore, overthrow the conclusions reachedon other grounds.     

Attention-Deficit/Hyperactivity Disorder Symptoms in Mothers and Fathers: Family Level Interactions in Relation to Parenting

Previous studies linking parent ADHD symptoms to parenting have typically focused on each parent individually. To provide a broader understanding of family context, in this study, levels of inattention and hyperactivity-impulsivity in mothers and fathers were examined, both individually and in combination, in relation to negative parenting and child-rearing disagreements. Two-parent families of 5 to 13 year old boys (126 with ADHD and 53 typically developing) participated. Parents reported their own ADHD symptoms and their perceptions of child-rearing disagreements. Parenting was measured using self-, partner-, and child-reports as well as observations. Controlling for child ADHD symptoms, inattention symptoms in fathers predicted parenting difficulties. For mothers, inattention symptoms were linked to parenting problems only when fathers also had high levels of inattention. In contrast, parenting was most problematic for both mothers and fathers in families in which fathers had higher and mothers had lower levels hyperactivity-impulsivity symptoms. These results remained essentially unchanged when child externalizing behavior and mother depression and hostility were controlled, but father depression reduced the significance of some interactions. The results highlight the importance of the match between father and mother levels of symptoms, and point to differential relations of parenting to inattention and hyperactivity-impulsivity symptoms in parents.     

Own and Others' Prior Experiences Influence Children's Imitation of Causal Acts

Young children learn from others' examples, and they do so selectively. We examine whether the efficacy of prior experiences influences children's imitation. Thirty-six-month-olds had initial experience on a causal learning task either by performing the task themselves or by watching an adult perform it. The nature of the experience was manipulated such that the actor had either an easy or a difficult experience completing the task. Next, a second adult demonstrated an innovative technique for completing it. Children who had a difficult first-person experience, and those who had witnessed another person having difficulty, were significantly more likely to adopt and imitate the adult's innovation than those who had or witnessed an easy experience. Children who observed another were also more likely to imitate than were those who had the initial experience themselves. Imitation is influenced by prior experience, both when it is obtained through one's own hands-on motor manipulation and when it derives from observing the acts of others.     

Age-related differences in the course of cognitive skill acquisition: the role of regional cortical shrinkage and cognitive resources

This study examined the impact of age-related differences in regional cerebral volumes and cognitive resources on acquisition of a cognitive skill. Volumes of brain regions were measured on magnetic resonance images of healthy adults (aged 22-80). At the early stage of learning to solve the Tower of Hanoi puzzle, speed and efficiency were associated with age, prefrontal cortex volume, and working memory. A similar pattern of brain-behavior associations was observed with perseveration measured on the Wisconsin Card Sorting Test. None of the examined structural brain variables were important at the later stages of skill acquisition. When hypertensive participants were excluded, the effect of prefrontal shrinkage on executive aspects of performance was no longer significant, but the effect of working memory remained.
