Aboriginal language knowledge and youth suicide

This brief report details a preliminary investigation into how community-level variability in knowledge of Aboriginal languages relate to “band”-level measures of youth suicide. In Canada, and, more specifically, in the province of British Columbia (BC), Aboriginal youth suicide rates vary substantially from one community to another. The results reported demonstrate that not only did this simple language-use indicator prove to have predictive power over and above that of six other cultural continuity factors identified in previous research, but also that youth suicide rates effectively dropped to zero in those few communities in which at least half the band members reported a conversational knowledge of their own “Native” language.     

Equally Shared Parenting

Conventional images of motherhood and fatherhood, social interactions, and gender-based job pressures push couples toward unequal parenting. Equally sharing parents resist those pressures, and construct equality through everyday negotiations and ongoing decisions about family and work. They do not believe that mothers are more responsible for children, or more suited to care for them, than fathers. They avoid gender-based decisions about jobs that reinforce a gender-based division of labor at home. Qualitative research is necessary to unravel the complex interactions between work and family arrangements, and to show how economic, social, and ideological factors constrain family arrangements, but are also transformed in their creation.     

Personal Relative Deprivation: A Look at the Grievous Consequences of Grievance

Stouffer et al. (1949) have first coined the term ‘relative deprivation’ to account for unexpected grievance expressed by members of a fortunate group. Many researchers have built on this work and have concluded that a person's feeling of deprivation is relative rather than absolute. In other words, deprivation stems from a social comparison with better‐off persons. In this chapter, a brief summary of the ground‐breaking research on relative deprivation is presented followed by an overview of research on overt and covert responses to personal relative deprivation. In accounting for the silent reactions of the underprivileged, we mainly focus on recent research linking personal relative deprivation to psychological disengagement. Turning to the responses of members of privileged groups, we take into account personal relative deprivation and gratification. Our concluding remarks suggest that responses of both the underprivileged and the privileged concur to the maintenance of the status quo.     

The heterogeneity of picture-supported narratives in Alzheimer's disease

This study describes discourse patterns produced by 46 Alzheimer disease (AD) patients and 53 normal elderly subjects in two picture-supported narratives. Nine measures derived from a cognitive model of discourse processing were obtained and submitted to cluster analysis. Results indicate that discourse patterns elicited from both stimuli were heterogeneous. Further, they fail to clearly differentiate between normal aging and AD in half of the AD patients. Discourse patterns are examined in light of various sources of heterogeneity including severity of cognitive impairment, subject characteristics, and task demands. The usefulness of discourse as a diagnostic and therapeutic tool is discussed.     

Cognitive discernible factors between schizophrenia and schizoaffective disorder

BACKGROUND: Schizophrenia (SZ) and schizoaffective disorders (SA) are associated with cognitive deficits. Generally, a schizoaffective diagnosis is associated with better prognosis on the level of social integration. It is also well established that cognition is an important factor for good social outcome in schizophrenia. We hypothesized that, although patients suffering from SA share symptoms with SZ, they can be differentiated on the basis of neurocognitive function and that SA perform better in several domains. METHOD: Performances of two groups SA (N = 13) and SZ (N = 44) were compared on several visual-motor tasks using CANTAB [Motor Screening (MOT), Reaction Time (RTI), Paired Associates Learning Task (PAL), and Stockings of Cambridge items (SOC)]. The two groups were matched for symptom severity. ANOVA with repeated measures was employed to determine whether any difference in cognitive scores during a 2-year period was significantly related to the diagnostic status. RESULTS: A significant and durable difference was observed between SZ and SA on motor screening and explicit memory tests where SA performed better. CONCLUSION: Neurocognitive tests may be relevant for distinguishing schizoaffective from schizophrenia, chiefly via tests tapping into visuo-spatial and visuo-motor coordination abilities (e.g., paired associated learning and motor screening).     

Auditory ERP in extremely premature 5-year-old children

The aim of this research was to test the hypothesis of a functional impairment in the automatic detection of deviant tones in 141 children born after 25 to 28 weeks of gestational age, as compared to 45 age-matched full-term control children. All of them were assessed at age 5 years 9 months and instructed to listen passively to two different pure tones (1000 vs 1200 Hz; 20 vs 80%) counterbalanced between ears. Rarity was thus defined by specific ear by tone combinations. The temporal N100 showed a clear contralateral functional organization of the central auditory pathway, especially for the left ear, but without group difference. By contrast, in full-term controls but not in premature children, the central N200 was specifically increased over frontal leads to rare stimuli as compared to frequent. Premature children demonstrated a lack of brain response when more complex processing integrating different informations was required.
