The development of categorical and coordinate spatial relations

Two classes of spatial relations can be distinguished in between and within object representations. Kosslyn [Kosslyn, S. M. (1987). Seeing and imagining in the cerebral hemispheres: A computational approach. Psychological Review, 94, 148–175] suggested that the right hemisphere (RH) is specialized for processing coordinate (metric) spatial information and the left hemisphere (LH) processes categorical (abstract) information more effectively. The present study examined the developmental pattern of spatial relation processing in 6–8-year old, 10–12-year old and adults. Using signal detection analyses we calculated sensitivity and bias scores for all age groups. The results indicated that older children and adults showed a greater response bias than younger children. Also, discrimination sensitivity for spatial relation changes clearly improved with age. For the oldest children (10–12-year old) and adults this improvement was accompanied by a RH specialization. In contrast with Kosslyn's claim, this RH advantage also applied to the processing of categorical spatial information. The results are discussed in terms of a right hemispheric specialization for spatial relation processing which matures with age.     

Meaningful coping with chronic pain: Exploring the interplay between goal violation,meaningful coping strategies and life satisfaction in chronic pain patients

Trying to cope with chronic pain is a highly demanding and challenging task and pain patients often need to reformulate goals or aspirations due to their pain condition. This goal violation is often related with experienced distress and requires coping processes in order to decrease the distress and stimulate a healthy adaptation. Some scholars, however, argued that in so‐called unsolvable or irreparable stressors such as chronic pain, conventional coping strategies like problem‐focused coping might not be the most adaptive option. In these situations, meaningful coping strategies attempting to transform the meaning of the stressful experience would be more accurate. In this study, we aim to test if goal violation triggers meaningful coping strategies over time and whether engagement in these meaningful coping strategies result in improved life satisfaction, as an indicator of adaptation. A longitudinal three wave study in a sample of paint patients (n = 125) tests whether goal violation triggers positive reappraisal and downward comparison, two possible meaningful coping strategies. The study furthermore tests if engagement in these strategies results in a better adaptation to the pain condition, reflected in higher life satisfaction. Results partially supported our hypotheses by pointing to the benevolent role of downward comparison on life satisfaction via decreased goal violation of pain patients. Our findings however did also show that positive reappraisal predicted lower life satisfaction via increased levels of appraised goal violation which questions the role of positive reappraisal as a genuine meaningful coping strategy. Implications and limitations are discussed.     

Self‐Monitoring and Counseling Skills: Skills‐Based Versus Interpersonal Process Recall Training

The purpose of this study was to investigate the role of personality traits of counselors‐in‐training with regard to counseling performance. There were no differences in pretest or posttest scores on the Skilled Counseling Scale (SCS) of high and low self‐monitoring counselors‐in‐training. Skill attainment may have more effect on personality traits than traits have on skill attainment. Both Interpersonal Process Recall (IPR) and Skilled Counselor Training Model (SCTM) groups improved their scores on the SCS, but the SCTM group improved significantly more than the IPR group.     

Category learning with a goal: how goals constrain conceptual acquisition

A novel task was used to examine the roles that goals play in concept acquisition. In Experiment 1, we varied the type of interaction, and thus the task goal, of participants working in a novel domain. Following those interactions, participant responses showed that they had organized their knowledge in terms of goal-relevant features. Using a variation of the same methodology, Experiment 2 provided evidence that the goal relevance also played a role in how the participants structured their knowledge of the items, specifically what information about the items was associated with differentiating the categories encountered. The results suggest that the goals not only highlighted particular features, they determined the centrality of those features in the conceptual knowledge. We discuss the results in terms of the goal-framework hypothesis; the idea that goals structure information and provide coherence to the acquired concepts. We discuss how this approach informs category learning research.     

Neural correlates of coherent and biological motion perception in autism

Recent evidence suggests those with autism may be generally impaired in visual motion perception. To examine this, we investigated both coherent and biological motion processing in adolescents with autism employing both psychophysical and fMRI methods. Those with autism performed as well as matched controls during coherent motion perception but had significantly higher thresholds for biological motion perception. The autism group showed reduced posterior Superior Temporal Sulcus (pSTS), parietal and frontal activity during a biological motion task while showing similar levels of activity in MT+/V5 during both coherent and biological motion trials. Activity in MT+/V5 was predictive of individual coherent motion thresholds in both groups. Activity in dorsolateral prefrontal cortex (DLPFC) and pSTS was predictive of biological motion thresholds in control participants but not in those with autism. Notably, however, activity in DLPFC was negatively related to autism symptom severity. These results suggest that impairments in higher-order social or attentional networks may underlie visual motion deficits observed in autism.     

Family Caregivers of Women with Physical Disabilities

Cross-sectional, correlational analyses of data from two separate studies were conducted to examine the correlates of adjustment among family caregivers of women with disabilities. Participants included 40 caregivers of women with spinal cord injuries in the first study and 53 caregivers of women with cerebral palsy, traumatic brain injury, and other neuromuscular disabilities in the second study. It was hypothesized that a negative problem-solving style would be associated with greater caregiver distress in both studies, and that caregiver adjustment would be associated with care recipient depression in the second study. As expected, results indicated that a higher negative orientation toward solving problems was associated with caregiver depression and lower well-being. However, in the second study, caregiver characteristics were not associated with care recipient depression. These data indicate that considerable variability exists in caregiver adjustment. Methodological limitations and the implications for research, service, and policy formation are! discussed.     

Parent‐implemented treatment for automatically maintained stereotypy

Automatically maintained stereotypy is common among children with autism spectrum disorder. The purpose of this study was to evaluate the effect of a multicomponent parent‐implemented intervention on the reduction of motor stereotypy for a child with autism. A 2‐year‐old child and her father participated in this study. The effect of a parent‐implemented intervention was evaluated using an alternating treatment design. The results indicated that the parent‐implemented treatment package including differential reinforcement, response blocking, and a competing stimulus decreased automatically maintained motor stereotypy.     

Use of three depression scales for evaluation of pretreatment severity and of improvement after treatment

We investigated the Castilian Spanish versions of three scales (the Hamilton Rating Scale for Depression, the Carroll Rating Scale for Depression, and the Montgomery-Asberg Depression Rating Scale) as to their suitability for classifying major depression patients in four levels of severity prior to treatment with tricyclic antidepressants, and also as to their suitability for classifying these patients in four improvement levels when administered posttreatment. Although the scales behaved quite similarly, each was most efficient at the task for which it had been designed, i.e., severity rating for the Hamilton and Carroll scales, improvement rating for the Montgomery-Asberg scale.     

Music perception and octave generalization in rhesus monkeys

Two rhesus monkeys were tested for octave generalization in 8 experiments by transposing 6- and 7-note musical passages by an octave and requiring same or different judgments. The monkeys showed no octave generalization to random-synthetic melodies, atonal melodies, or individual notes. They did show complete octave generalization to childhood songs (e.g., "Happy Birthday") and tonal melodies (from a tonality algorithm). Octave generalization was equally strong for 2-octave transpositions but not for 0.5- or 1.5-octave transpositions of childhood songs. These results combine to show that tonal melodies form musical gestalts for monkeys, as they do for humans, and retain their identity when transposed with whole octaves so that chroma (key) is preserved. This conclusion implicates similar transduction, storage, processing, and relational memory of musical passages in monkeys and humans and has implications for nature-nurture origins of music perception.     

Using behavioral skills training with preservice teachers in the university classroom

Preservice and novice teachers often identify behavior management as an area of weakness that they attribute to a lack of sufficient instruction during their teacher preparation. Behavioral skills training (BST) is an evidence‐based teaching methodology based on the principles of applied behavior analysis used to teach new skills. This study investigated the use of BST in the university setting to teach undergraduate preservice teachers enrolled in a field‐based special education course to implement a token economy during small group instruction with children. A single‐case research design was used to assess the effectiveness of using BST by evaluating accuracy of implementation before and after BST. Results showed BST was an effective teaching procedure and social validity measures collected from the preservice teachers indicated BST was acceptable to all participants. Limitations and needs for future research are discussed.
