Word learning in deaf children with cochlear implants: effects of early auditory experience

Word-learning skills were tested in normal-hearing 12- to 40-month-olds and in deaf 22- to 40-month-olds 12 to 18 months after cochlear implantation. Using the Intermodal Preferential Looking Paradigm (IPLP), children were tested for their ability to learn two novel-word/novel-object pairings. Normal-hearing children demonstrated learning on this task at approximately 18 months of age and older. For deaf children, performance on this task was significantly correlated with early auditory experience: Children whose cochlear implants were switched on by 14 months of age or who had relatively more hearing before implantation demonstrated learning in this task, but later implanted profoundly deaf children did not. Performance on this task also correlated with later measures of vocabulary size. Taken together, these findings suggest that early auditory experience facilitates word learning and that the IPLP may be useful for identifying children who may be at high risk for poor vocabulary development.     

Neural correlates of socioeconomic status in the developing human brain

Socioeconomic disparities in childhood are associated with remarkable differences in cognitive and socio-emotional development during a time when dramatic changes are occurring in the brain. Yet, the neurobiological pathways through which socioeconomic status (SES) shapes development remain poorly understood. Behavioral evidence suggests that language, memory, social-emotional processing, and cognitive control exhibit relatively large differences across SES. Here we investigated whether volumetric differences could be observed across SES in several neural regions that support these skills. In a sample of 60 socioeconomically diverse children, highly significant SES differences in regional brain volume were observed in the hippocampus and the amygdala. In addition, SES × age interactions were observed in the left superior temporal gyrus and left inferior frontal gyrus, suggesting increasing SES differences with age in these regions. These results were not explained by differences in gender, race or IQ. Likely mechanisms include differences in the home linguistic environment and exposure to stress, which may serve as targets for intervention at a time of high neural plasticity.     

Visual laterality in belugas (Delphinapterus leucas) and Pacific white-sided dolphins (Lagenorhynchus obliquidens) when viewing familiar and unfamiliar humans

Lateralization of cognitive processes and motor functions has been demonstrated in a number of species, including humans, elephants, and cetaceans. For example, bottlenose dolphins (Tursiops truncatus) have exhibited preferential eye use during a variety of cognitive tasks. The present study investigated the possibility of visual lateralization in 12 belugas (Delphinapterus leucas) and six Pacific white-sided dolphins (Lagenorhynchus obliquidens) located at two separate marine mammal facilities. During free swim periods, the belugas and Pacific white-sided dolphins were presented a familiar human, an unfamiliar human, or no human during 10–15 min sessions. Session videos were coded for gaze duration, eye presentation at approach, and eye preference while viewing each stimulus. Although we did not find any clear group level lateralization, we found individual left eye lateralized preferences related to social stimuli for most belugas and some Pacific white-sided dolphins. Differences in gaze durations were also observed. The majority of individual belugas had longer gaze durations for unfamiliar rather than familiar stimuli. These results suggest that lateralization occurs during visual processing of human stimuli in belugas and Pacific white-sided dolphins and that these species can distinguish between familiar and unfamiliar humans.     

Fear Associated With September 11 Television Coverage in Oklahoma City Bombing Survivors

This study explored television viewing of the September 11 attacks in 99 survivors of the Oklahoma City bombing and examined the relationships of event-related television viewing with concerns about safety and danger in survivors with and without bombing-related posttraumatic stress disorder. The number of hours of viewing September 11 television coverage was related to worry about personal and family danger and to increased checking on loved ones but not to September 11–related posttraumatic responses. Some bombing survivors discontinued September 11 media contact due to fear. The findings suggest the importance of monitoring television viewing in survivors of prior incidents.     

Development of the Multidimensional Peer Victimization Scale–Revised (MPVS-R) and the Multidimensional Peer Bullying Scale (MPVS-RB)

Peer victimization is a frequent occurrence for many adolescents; however, some of the psychometric properties of self-report scales assessing these experiences remain unclear. Furthermore, with an increase in access to technology, electronic aggression should also be considered. The authors examined the psychometric properties of the Multidimensional Peer Victimization Scale (MPVS; Mynard & Joseph, 2000), and developed versions to include the assessment of electronic aggression according to whether the adolescent was the target or perpetrator of peer victimization. A total of 371 (191 girls and 180 boys; M_age = 13 years 4 months, SD_age = 1 year 2 months) adolescents in the United Kingdom completed the MPVS including five newly developed items assessing electronic aggression, a version of the MPVS designed to assess victimization perpetration, and a measure of self-esteem. Confirmatory factor analyses yielded a five-factor structure comprising: Physical, social manipulation, verbal, attacks on property, and electronic for both scales. Convergent validity was established through negative associations between the victimization scales and self-esteem. Sex differences also emerged. One revised scale and one new scale are subsequently proposed: The MPVS–Revised and the Multidimensional Peer Bullying Scale.     

Why Reasons Skepticism is Not Self‐Defeating

Abstract: Radical meta‐normative skepticism is the view that no standard, norm, or principle has objective authority or normative force. It does not deny that there are norms, standards of correctness, and principles of various kinds that render it possible that we succeed or fail in measuring up to their prerogatives. Rather, it denies that any norm has the status of commanding with objective authority, of giving rise to normative reasons to take seriously and follow its demands. Two powerful transcendental arguments challenge this view. First, skepticism is said to be self‐defeating: Settling what to accept, and in particular whether to accept skepticism, appears to be a reason‐guided enterprise. How can skeptics coherently support their view by citing reasons in their favor after they just rejected them throughout? Second, there is the practical‐deliberative version, most recently developed by David Enoch: We are essentially deliberative creatures. Yet deliberation appears to require that there are correct answers in the form of normative reasons to our practical questions. Thus confidence in the sensible nature of deliberation should inspire confidence in reasons. The essay undermines both transcendental arguments by demonstrating, first, how to support skepticism without deserting its tenets, and, second, how to deliberate in skeptical fashion.     

Heterogeneity in Verbal Memory: A Marker of Preclinical Alzheimer's Disease?

ABSTRACT

Demonstrations of memory changes in those at risk for Alzheimer's disease by the presence of the APOE e4 allele have been inconsistent to date. The present study went beyond traditional analyses of central tendency (i.e., group differences on mean test scores) and also conducted distribution analyses to search for subtle cognitive differences in subgroups of normal-functioning elderly persons with the APOE e4 genotype. The results of the study revealed that (a) the e4 and non-e4 groups failed to differ in terms of their mean scores on tests of memory and verbal skills; and (b) relative to the non-e4 group, the e4 subjects had significantly greater heterogeneity of variance on the memory measures but not on fundamental verbal skills. Logistic regression analyses indicated that the discrepancy in scores on the memory measures was a significant predictor of genotype group membership (82% correct classification rate). Implications of these findings for the detection of a preclinical phase of AD are discussed.     

La Caze on Envy and Resentment

Abstract

Marguerite La Caze has recently published a stimulating analysis of the emotions of envy and resentment in which she argues that to envy others for a benefit they have received or to resent them for such a reason can be ethically acceptable in cases where that benefit has been unjustly obtained (La Caze, 2001). I question this on the ground that the judgement that the benefit has been unjustly obtained plays a more complex role in the structure of envy and resentment than La Caze allows and should alter the nature of the feeling that is evoked. From the perspective of virtue ethics there is nothing creditable about still feeling envy or resentment in such circumstances.     

Subjective Well-Being as a Dynamic and Agentic System: Evidence from a Longitudinal Study

Subjective well-being (SWB) comprises individual differences in life satisfaction (LS), positive affect (PA), and negative affect (NA), and is typically conceptualized as an important life outcome. In contrast, Shmotkin (Rev Gen Psychol 9:291–325, 2005) proposed that SWB is a dynamic and agentic system that promotes optimal functioning, and is organized within individuals as configurations of LS, PA, and NA. We investigated three fundamental features of this novel framework. A 3-year, two-wave longitudinal study (N = 446 Canadian students; Mage = 18.67; 73 % female) was undertaken. The same set of five SWB configurations were observed at each time point, including congruous and incongruous profiles. Consistent with the hypothesized dynamic nature of the SWB system intraindividual stability in SWB configurations (operationalized in terms of categorical cluster membership and prototypicality scores) was moderate. In support of the proposed responsive nature of the SWB system, changes over time in individuals’ SWB configurations were predicted by changes in psychological, physical, and interpersonal functioning. Consonant with the proposed promotive role of the SWB system, positive functioning and changes in functioning over time were predicted by individuals’ SWB configurations and changes in configurations. The present work provides support for the proposed dynamic and agentic nature of SWB. Unique insights offered by a configural perspective on SWB are discussed.     

Work conditions and employees' self-set goals: goal processes enhance prediction of psychological distress and well-being

Although previous theory and research suggest that employee well-being should be predicted by work conditions (viz., Karasek and colleagues' job demands-control-social support [J-DCS] model), other factors are also likely to be important. In this study, the authors consider correlates of employee psychological distress and well-being using a goal-focused approach grounded in Ford's (1992) motivational systems theory. Specifically, work conditions and midlevel work goal processes (WGP) were examined in a questionnaire study of health care employees. Regarding predictions derived from the J-DCS model, the authors found full support for the iso-strain, partial support for the nonlinearity, and no support for the buffer hypothesis. Of importance, however, WGP (i.e., cognitions and emotions involved in the pursuit of self-set work goals) explained variance in job satisfaction, burnout, depression, and somatic complaints, over and above that of the J-DCS model. This suggests that investigation of WGP can enhance our understanding of employee psychological distress and well-being.
