Social Skills Differences among Attention-Deficit/Hyperactivity Disorder Types in a Chat Room Assessment Task

This study assessed social skills in 116 children aged 7-12 with ADHD-Combined Type (ADHD-C; n=33), ADHD-Inattentive Type (ADHD-I; n=45), and comparison children (n=38), with consideration of the role sluggish cognitive tempo (SCT) symptoms play in distinguishing profiles. Social skills were assessed using a novel computerized chat room task, in which participants were encouraged to join a conversation and type messages to interact with four computer-simulated peers. Every participant received the identical stimulus from the simulated peers, but was free to respond to it in his or her own unique way. Relative to comparison children, children with ADHD-C made off-topic and hostile responses; children with ADHD-I made off-topic responses, few responses and showed poor memory for the conversation. ADHD subtype differences remained after statistical control of IQ, reading achievement, typing skill, and comorbid disruptive behavior disorders. SCT symptoms, most prevalent among children with ADHD-I, predicted a distinct pattern of social withdrawal and lower hostility. Parent and teacher ratings and in-vivo observations of social skills correlate with this new measure.     

Quality benchmarks in undergraduate psychology programs

Performance benchmarks are proposed to assist undergraduate psychology programs in defining their missions and goals as well as documenting their effectiveness. Experienced academic program reviewers compared their experiences to formulate a developmental framework of attributes of undergraduate programs focusing on activity in 8 domains: curriculum, assessment issues, student learning outcomes, program resources, student development, faculty characteristics, program climate, and administrative support. A continuum of performance was conceptualized for each attribute in each of the domains to characterize underdeveloped, developing, effective, and distinguished achievement for undergraduate programs. The authors hope to inspire a national conversation about program benchmarks in psychology in order to improve program quality, encourage more effective program reviews, and help optimally functioning programs compete more successfully for resources on the basis of their distinguished achievements.     

Manipulating establishing operations to verify and establish stimulus control during mand training

Acquisition of verbal behavior is a major goal of interventions for children with developmental disabilities. We evaluated the effectiveness of manipulation of an establishing operation for functional discriminated mands. Four individuals with developmental disabilities participated in a training procedure designed to teach two separate mands for two separate preferred items. Participants were taught to mand using picture cards. Following training, the manipulation of the establishing operation was used to assess and establish discriminated manding. This manipulation involved providing free access to one of the preferred items, such that there should be no motivation to ask for it, while motivation to ask for the other item remained in place. Three of the 4 participants acquired discriminated manding using topographically similar responses (picture cards). One participant did not acquire a discriminated mand until topographically distinct mands were taught (vocal and picture card). Results suggest that discrimination training is not necessarily sufficient to teach discriminated manding when more than one picture card showing preferred items is used. In addition, manipulation of the establishing operation served as an appropriate assessment tool for the verification of discriminated manding as well as a possible training tool to establish discriminated manding.     

The virtual haptic display: A device for exploring 2-D virtual shapes in the tactile modality

In order to understand better the processes involved in the perception of shape through touch, someelement of control is required over the nature of the shape presented to the hand and the presentation timing. To that end, we have developed a cost-effective, computer-controlled apparatus for presenting haptic stimuli using active touch, known as a virtual haptic display (VHD). The operational principle behind this device is that it translates black and white visual images into topographic, 2-D taxel (tactile pixel) arrays, along the same principle using in Braille letters. These taxels are either elevated or depressed at any one time representing white and black pixel colors of the visual image, respectively. To feel the taxels, the participant places their fingers onto a carriage which can be moved over the surface of the device to reveal a virtual shape. We conducted two experiments and the results show that untrained participants are able to recognize different, simple and complex, shapes using this apparatus. The VHD apparatus is therefore ideal at presenting 2-Dshapes through touch alone. Moreover,this device and its supporting software can also be used for presenting computer-controlled stimuli in cross-modal experiments.     

Neighborhood crime as a predictor of individual differences in emotional processing and regulation

Emerging research suggests that early exposure to environmental adversity has important implications for the development of brain regions associated with emotion regulation, yet little is known about how such adversity translates into observable differences in children's emotion‐related behavior. The present study examines the relationship between geocoded neighborhood crime and urban pre‐adolescents' emotional attention, appraisal, and response. Results indicate that living in a high‐crime neighborhood is associated with greater selective attention toward negatively valenced emotional stimuli on a dot probe task, less biased appraisal of fear on a facial identification task, and lower rates of teacher‐reported internalizing behaviors in the classroom. These findings suggest that children facing particularly high levels of environmental threat may develop different regulatory processes (e.g. greater use of emotional suppression) than their peers from low‐crime neighborhoods in order to manage the unique stressors and social demands of their communities.
