Innovation in Guidance: A Mobile Counseling Center

A mobile counseling center staffed by 4 counselors serves high schools in 4 counties of southern Indiana. The operation of the center is designed to enrich, supplement, and improve the quality of counseling services for secondary students of the area. The mobile center also serves as a model to stimulate the development of exemplary and innovative guidance services in regular school programs.     

Functions in biological kind classification

Biological traits that serve functions, such as a zebra's coloration (for camouflage) or a kangaroo's tail (for balance), seem to have a special role in conceptual representations for biological kinds. In five experiments, we investigate whether and why functional features are privileged in biological kind classification. Experiment 1 experimentally manipulates whether a feature serves a function and finds that functional features are judged more diagnostic of category membership as well as more likely to have a deep evolutionary history, be frequent in the current population, and persist in future populations. Experiments 2-5 reveal that these inferences about history, frequency, and persistence account for nearly all the effect of function on classification. We conclude that functional features are privileged because their relationship with the kind is viewed as stable over time and thus as especially well suited for establishing category membership, with implications for theories of classification and folk biological understanding.     

Life events and personality predicting loneliness among centenarians: findings from the Georgia Centenarian Study

Regarding the purpose of this study, the researchers analyzed the roles that both life events (life-time positive events and life-time negative events) and personality (Neuroticism, Extraversion, Trust, Competence, and Ideas) played in participants of the Georgia Centenarian Study. The researchers analyzed these variables to determine whether they predicted loneliness. Analyses indicated that life-time negative events significantly predicted loneliness. In essence, the higher was the number of life-time negative life events, the higher was the loneliness score. Moreover, Neuroticism, Competence, and Ideas were all significant predictors of loneliness. The higher was the level of Neuroticism and intellectual curiosity, the higher was the level of loneliness, whereas the lower was the level of Competence, the higher was the level of loneliness. In addition, both life-time positive and life-time negative life events were significant predictors of Neuroticism. The higher was the number of life-time positive events, the lower was the level of Neuroticism, and the higher was the number of life-time negative events, the greater was the level of Neuroticism. These results indicated that life-time negative events indirectly affect loneliness via Neuroticism. Last, our results indicated that the Competence facet mediated the relationship between lifetime negative life events and loneliness. Life-time negative life events significantly affected centenarians' perceived competence, and Competence in turn significantly affected the centenarians' loneliness. These results as a whole not only add to our understanding of the link between personality and loneliness, but also provide new insight into how life events predict loneliness.     

Cue-integration and context effects in speech: Evidence against speaking-rate normalization

Listeners are able to accurately recognize speech despite variation in acoustic cues across contexts, such as different speaking rates. Previous work has suggested that listeners use rate information (indicated by vowel length; VL) to modify their use of context-dependent acoustic cues, like voice-onset time (VOT), a primary cue to voicing. We present several experiments and simulations that offer an alternative explanation: that listeners treat VL as a phonetic cue rather than as an indicator of speaking rate, and that they rely on general cue-integration principles to combine information from VOT and VL. We demonstrate that listeners use the two cues independently, that VL is used in both naturally produced and synthetic speech, and that the effects of stimulus naturalness can be explained by a cue-integration model. Together, these results suggest that listeners do not interpret VOT relative to rate information provided by VL and that the effects of speaking rate can be explained by more general cue-integration principles.     

The past,present, and future of computational models of cognitive development

Does modeling matter? We address this question by providing a broad survey of the computational models of cognitive development that have been proposed and studied over the last three decades. We begin by noting the advantages and limitations of computational models. We then describe four key dimensions across which models of development can be organized and classified. With this taxonomy in hand, we focus on how the modeling enterprise has evolved over time. In particular, we separate the timeline into three overlapping historical waves and highlight how each wave of models has not only been shaped by developmental theory and behavioral research, but in return also provided valuable insights and innovations to the study of cognitive development.     

The Political Justification of Migrant Workers in Alberta,Canada

Considering a series of oil-driven economic booms, the use of inter-provincial and international migrant labour has become an important part of labour market policy in the Canadian province of Alberta. The increased use of temporary foreign workers is controversial. Narrative analysis of legislators’ statements in the legislature and the press between 2000 and 2011 reveals the government using three narratives to justify policies encouraging greater use of foreign migrant workers: (1) labour shortages require migrant workers, (2) migrants do not threaten Canadian jobs and (3) migrants are not being exploited. Close scrutiny of each narrative demonstrates them to be largely invalid. This suggests a significant disconnect between the real and espoused reasons for the significant changes to labour market policy, changes that advantage employers and disadvantage both Canadian and foreign workers. The findings are relevant to understand the political dynamics of economically related migration.     

Health Related Quality of Life in Children with Congenital Heart Disease

Health-related quality of life in children with congenital heart disease (CHD) was compared to that of healthy children. Furthermore, agreement between child and parent reports was examined. In addition, differences in quality of life related to the severity of CHD were evaluated. One hundred children with CHD aged between 8-18 years and their parents answered a health-related quality of life-questionnaire during their visit to the paediatric cardiology outpatient department. CHD children reported reduced motor functioning and autonomy compared to healthy children. Parents of children with CHD reported their children to have a reduced quality of life in the domains of: motor functioning, autonomy and cognitive functioning. Agreement between child and parent reports was moderate. Children systematically reported lower health related quality of life on the domain of positive emotions than did parents. Health related quality of life in children with CHD appeared not to be influenced by severity of the disease. In conclusion, regardless of the severity of the disease, children with CHD reported their health related quality of life on several domains to be lower than that of healthy children. This means that on several domains, the emotional impact of problems in health status is greater for children with CHD than for healthy children. When CHD patients visit the clinic, it is important that physicians actively ask patients as well as parents about the child's motor functioning, autonomy and cognitive functioning. Children with problems in these domains can then be identified, and psychological interventions can take place at an early stage.
