Assessing indices of happiness and unhappiness in individuals with developmental disabilities: a review

The behavioral deficits of individuals with profound multiple disabilities (PMD) make it difficult to assess their satisfaction and quality of life. To address this problem, researchers have recently evaluated affective behavior (i.e., indices of happiness and unhappiness) to document the effects of therapeutic interventions and to assist with clinically relevant decisions. We review the recent literature on indices of happiness and unhappiness and discuss its major themes. In addition, potential concerns with this technology are discussed and clinical recommendations are provided. Copyright © 2007 John Wiley & Sons, Ltd.     

The social construction of race: biracial identity and vulnerability to stereotypes

Multiracial individuals are more likely to have a heightened awareness of race as a social construct than monoracial individuals. This article examines the impact that a heightened awareness of race as a social construct has on the relationship between racial stereotypes and performance. Study 1 finds that multiracial individuals reported subscribing less to the notion that race biologically determines ability. Study 2 finds that monoracial individuals show stereotype activation, whereas multiracial individuals show stereotype inhibition in reaction to race salience. Study 3 draws on the work on stereotypes and performance to test the susceptibility of multiracial individuals to racial stereotypes about ability. The authors find that Asian/White and Black/White multiracial individuals were less susceptible to racial stereotypes than monoracial individuals. Whereas monoracial participants showed significant performance changes in reaction to race salience, multiracial individuals did not. Study 4 finds that emphasizing the social construction of race buffers individuals from stereotype threat effects.     

TouchStat v. 3.00: A new and improved Monte Carlo adjunct for the sequential touching task

The sequential-touching procedure is employed by researchers studying nonlinguistic categorization in toddlers. TouchStat 3.00 is introduced in this article as an adjunct to the sequential-touching procedure, allowing researchers to compare children's actual touching behavior to what might be expected by chance. Advantages over the Thomas and Dahlin (2000) framework include ease of use, and fewer assumptive limitations. Improvements over TouchStat 1.00 include calculation of chance probabilities for multiple "special cases" and for immediate intercategory alternations. A new feature for calculating mean run length is also included.     

Developmental bias for number words in the intraparietal sulcus

Children and adults show behavioral evidence of psychological overlap between their early, non‐symbolic numerical concepts and their later‐developing symbolic numerical concepts. An open question is to what extent the common cognitive signatures observed between different numerical notations are coupled with physical overlap in neural processes. We show that from 8 years of age, regions of the intraparietal sulcus (IPS) that exhibit a numerical ratio effect during non‐symbolic numerical judgments also show a semantic distance effect for symbolic number words. In both children and adults, the IPS showed a semantic distance effect during magnitude judgments of number words (i.e. larger/smaller number) but not for magnitude judgments of object words (i.e. larger/smaller object size). The results provide novel evidence of conceptual overlap between neural representations of symbolic and non‐symbolic numerical values that cannot be explained by a general process, and present the first demonstration of an early‐developing dissociation between number words and object words in the human brain.     

Keeping track of where we are: Spatial working memory in navigation

Spatial working memory (WM) seems to include two types of spatial information: locations and relations. However, this distinction has been based on small-scale tasks. Here, we used a virtual navigation paradigm to examine whether WM for locations and relations applies to the large-scale spatial world. We found that navigators who successfully learned two routes and also integrated them were superior at maintaining multiple locations and multiple relations in WM. However, over the entire spectrum of navigators, WM for spatial relations, but not locations, was specifically predictive of route integration performance. These results lend further support to the distinction between these two forms of spatial WM and point to their critical role in individual differences in navigation proficiency.     

Neural correlates of rumination in adolescents with remitted major depressive disorder and healthy controls

The aim of the present study was to use fMRI to examine the neural correlates of engaging in rumination among a sample of remitted depressed adolescents, a population at high risk for future depressive relapse. A rumination induction task was used to assess differences in the patterns of neural activation during rumination versus a distraction condition among 26 adolescents in remission from major depressive disorder (rMDD) and in 15 healthy control adolescents. Self-report depression and rumination, as well as clinician-rated depression, were also assessed among all participants. All of the participants recruited regions in the default mode network (DMN), including the posterior cingulate cortex, medial prefrontal cortex, inferior parietal lobe, and medial temporal gyrus, during rumination. Increased activation in these regions during rumination was correlated with increased self-report rumination and symptoms of depression across all participants. Adolescents with rMDD also exhibited greater activation in regions involved in visual, somatosensory, and emotion processing than did healthy peers. The present findings suggest that during ruminative thought, adolescents with rMDD are characterized by increased recruitment of regions within the DMN and in areas involved in visual, somatosensory, and emotion processing.     

All role transitions are not experienced equally: Associations among self-change,emotional reactions,and self-concept clarity

Individuals experience numerous transitions across various roles during their lives. These role transitions can be disruptive to the way individuals view their identity, and thus their well-being; however, role transitions do not affect all individuals equally. Therefore, in the current work, we focused on two factors which may influence self-concept clarity and explain differential experiences following role transitions. We tested the relationship between the amount of self-change and positive emotions in reaction to a role transition predicting self-concept clarity, including both role entries (e.g. parenthood/new relationships, Studies 1–4) and role exits (e.g. divorce/job loss, Studies 3 and 4). Across several studies and all role transitions, we found that among individuals who experienced low levels of positive emotions after a role transition, greater self-change predicted reduced self-concept clarity. Among individuals who experienced higher levels of positive emotionality, this association did not emerge.     

Paws for Intervention: Perceptions About the Use of Dogs in Schools

Research in the field of animal-assisted therapy has shown that therapy dogs have a positive social-emotional impact on individuals in hospitals, nursing homes, and counseling. Recently, the literature has suggested that therapy dogs can yield positive psychological, social, and academic outcomes in schools, although this research is quite limited. The intent of this study was to examine perceptions on the effectiveness of therapy dogs in schools for promoting students’ psychological well-being, and an overall positive school climate. Preliminary evidence shows faculty and students from four rural school districts across Western New York indicated support for this emerging and viable school intervention. This qualitative and quantitative insight can help guide future research.     

Suicide risk screening in an urban high school

Qualitative data from an empirical study of adolescent suicide risk were analyzed to examine the screening component built in to a larger protocol. It was determined that a significant number of students were being identified as being in need of follow-up. Although the majority (88.7%) of students screened met criteria for placement in the no indicators (of risk) category, 3.8% evidenced apparent need of follow-up, 4.4% qualified for notable concern, and 3.1% were deemed to be at-risk or in crisis. Several gender and ethnic differences in risk category status are also discussed. The system utilized at the school and examples of the range of interventions utilized are discussed. Evidence for the positive effects of this screening on individual students and the school as a whole are presented. Arguments for the regular use of screening measures in high schools and suggestions for implementation are also given.
