Provision of leisure activities for the reduction of challenging behavior

Behavioral treatment of challenging behaviors, such as aggression, self-injury, property destruction, and stereotyped movement is often a priority in residential facilities for persons with developmental disabilities. If these behaviors occur when the client is otherwise unengaged, a potentially effective treatment may be to provide alternative activities. In the present study, 3 adults with severe disabilities were observed. During baseline, these 3 individuals frequently displayed challenging behavior at times when they were otherwise unengaged. Opportunities to participate in leisure activities were then provided to each client in a multiple-baseline design. Provision of leisure opportunities was associated with increased adaptive behavior and collateral reductions in problem behaviors. The effectiveness of the intervention procedures suggest that these challenging behaviors may have been related to the lack of alternative activities.     

The effect of invalid task parameters on short-term motor memory

Two experiments tested the influence of information from an invalid movement parameter on short-term motor memory for a valid task parameter. Experiment 1 showed that invalid task distance information affected location retention. Experiment 2 showed that invalid task location information affected task distance retention. These findings strengthen the evidence that the codes important for short-term motor retention are affected by a variety of factors within the movement context.     

Word norms for blind and sighted subjects: Familiarity,concreteness, meaningfulness,imageability, imagery modality,and word associations

Normative values for word characteristics were obtained from a sample of 12 college-educated, totally congenitally blind subjects on the basis of their ratings of 161 nouns on scales of familiarity, concreteness, meaningfulness, and imageability. The dominant modality of imagery for each image-evoking word and the strongest word associate for each item also were recorded. The same data were collected for a group of sighted subjects, both to provide a comparison group for the blind subjects and to test the comparability of sighted subjects’ ratings with existing norms. Ratings for sighted subjects correlated strongly with those norms, although the coefficients were slightly higher for ratings of concreteness and imageability than for ratings of familiarity and meaningfulness. Ratings of blind subjects correlated only slightly lower with existing norms for imagery and concreteness, but considerably lower for familiarity and meaningfulness.     

Savoring interventions for mothers of young children: Mechanisms linking relational savoring and personal savoring to reflective functioning

Parenting interventions can improve parenting outcomes, with widespread implications for children's developmental trajectories. Relational savoring (RS) is a brief attachment-based intervention with high potential for dissemination. Here we examine data from a recent intervention trial in order to isolate the mechanisms by which savoring predicts reflective functioning (RF) at treatment follow-up through an examination of the content of savoring sessions (specificity, positivity, connectedness, safe haven/secure base, self-focus, child-focus). Mothers (N = 147, M_age = 30.84 years, SD_age = 5.13; Race: 67.3% White/Caucasian, 12.9% other or declined to state; 10.9% biracial/multiracial, 5.4% Asian, 1.4% Native American/Alaska Native, 2.0% Black/African American; Ethnicity: 41.5% Latina) of toddlers (M_age = 20.96 months, SD_age = 2.50; 53.5% female) were randomized to four sessions of RS or personal savoring (PS). Both RS and PS predicted higher RF, but through different means. RS was indirectly associated with higher RF through greater connectedness and specificity of savoring content, while PS was indirectly associated with higher RF through greater self-focus in savoring content. We discuss the implications of these findings for treatment development and for our understanding of the emotional experience of mothers of toddlers.     

The lack of pseudohomophone priming effects with short durations in reading and naming

The priming effect of pseudohomophones was assessed in reading and naming tasks. In two experiments using the fast priming paradigm in reading, there were no pseudohomophone priming effects when the prime duration was 32, 44, or 56 ms from the beginning of a fixation. In a third experiment, using a naming task with isolated words, there were also no pseudohomophone priming effects with prime durations of 32, 44, and 56 ms, but there was with a 200-ms prime duration. The results suggest that pseudohomophone priming doesn't occur at an early stage of reading (in the first 60 ms from the beginning of fixation), but occurs at a later stage (within the first 200 ms).     

Neurofibromatosis Type 1 in Genetic Counseling Practice: Recommendations of the National Society of Genetic Counselors

The objective of this document is to provide recommendations for the genetic counseling of patients and families undergoing evaluation for neurofibromatosis type 1 (NF1) or who have received a diagnosis of NF1. These recommendations are the opinions of a multi-center working group of genetic counselors with expertise in the care of individuals with NF1. These recommendations are based on the committee’s clinical experiences, a review of pertinent English language medical articles, and reports of expert committees. These recommendations are not intended to dictate an exclusive course of management, nor does the use of such recommendations guarantee a particular outcome. These recommendations do not displace a health care provider’s professional judgment based on the clinical circumstances of an individual patient. Both Heather B. Radtke and Courtney D. Sebold contributed equally to this document.     

Pediatric trichotillomania: descriptive psychopathology and an open trial of cognitive behavioral therapy

In study 1, 46 children and adolescents with trichotillomania who sought treatment at 2 specialty outpatient clinics were assessed. Most children reported pulling hair from multiple sites on the body, presented with readily visible alopecia, reported spending 30-60 minutes per day pulling or thinking about pulling, and reported experiencing significant distress about their symptoms. Most were described by their parents as having significant problems in school functioning. Few children met criteria for obsessive-compulsive disorder or tic disorder. Child and family rates of other forms of psychopathology were high. In study 2, 22 of these children were enrolled in an open trial of individual cognitive behavioral therapy with particular attention to relapse prevention. Trichotillomania severity decreased significantly and 77% of children were classified as treatment responders at post-treatment and 64% at 6-month follow-up.     

Changes in quality of life following cognitive-behavioral therapy for obsessive-compulsive disorder

Cognitive-behavioral therapy (CBT) incorporating exposure and response prevention is a first line treatment for obsessive-compulsive disorder (OCD). Although, the efficacy of CBT in reducing OCD symptoms is well documented, less is known about its effects on quality of life (QOL). In the current study, functional impairment aspects of QOL (as measured by the Sheehan Disability Scale) were assessed among 70 adult outpatients with OCD before and after CBT. Statistically significant improvements in QOL and large pre- to post-treatment effect sizes were observed for work, social, and family functioning. Improvements in social and family functioning were predicted by improvements in OCD symptom severity even after controlling for improvements in depressive symptoms. In addition, clinically significant change in OCD symptoms and QOL were highly related, although there was a subset of participants whose symptoms improved without corresponding improvements in QOL. These results suggest that the effects of CBT may extend beyond OCD symptom reduction to QOL.     

Proprioception and Stimulus-Response Compatibility

Sixteen subjects pressed a left or right key in response to lateralized visual stimuli, in uncrossed (left index finger on left key, right finger on right key) and crossed conditions (left finger on right key and vice versa), with varying finger separations. Visual, tactile, or 'efference copy' cues about relative finger positions were unavailable. Subjects had to press the key on the same side as (compatible group) or opposite side to the stimulus (incompatible group). Separate proprioceptive judgements of the relative finger positions were obtained. Findings of an overall reaction time (RT) advantage for compatible instructions and for uncrossed hands were replicated. With decreasing finger separation the RT advantage for compatible instructions decreased, and the probability of responding with either hand increased. The compatibility effect disappeared completely at the 6-cm crossed position, not at the position that was hardest to judge proprioceptively. This suggests that two forms of neural activation are summed: automatic activation of the anatomically same-side limb, and an integrated, rule-based activation. The results further demonstrate that independent proprioceptive cues from each limb, unassociated with skin contact between the limbs, can mediate the determination of relative position for response selection in stimulus-response compatibility tasks.     

Influences Between Online‐Exclusive,Conjoint and Offline‐Exclusive Friendship Networks: The Moderating Role of Shyness

Prior research has indicated that shy adolescents are more motivated to form friendships online than to form friendships offline. Little is known about whether having friendships found exclusively online may impact self‐esteem and forming offline friendships for these adolescents. This study therefore aimed to provide insight into the moderating role of shyness in the longitudinal interplay between friendships in online and offline contexts in early adolescence. Adolescents and their friends (193 girls, 196 boys; M_age = 13.29) were followed with three consecutive measurements with intervals of eight months. Results showed that particularly for shy adolescents, having friends exclusively online predicted increases in self‐esteem. Self‐esteem, in turn, was found to predict forming more friendships found both offline and online and forming more friendships found exclusively offline. Thus, findings supported the social compensation perspective that shy adolescents may benefit from having friends exclusively online, as these friendships may increase self‐esteem, thereby facilitating the formation of friendships found partially and completely offline.
