Influences of preclinical dementia and impending death on the magnitude of age-related cognitive deficits

The authors examined the influence of preclinical dementia and impending death on the cross-sectional relationship between age and performance in tasks assessing episodic memory, visuospatial skill, and verbal fluency. Increasing age was associated with a general decrease in cognitive performance. In addition, those who were to be diagnosed with dementia or had died by a 3-year follow-up, were older, and performed at a lower level than the remaining sample across all cognitive tasks at baseline. Nevertheless, removal of the preclinical dementia and impending death groups from the original sample affected the cross-sectional age-cognition relations relatively little. This pattern of findings suggests that the biological aging process exerts negative influences on cognitive functioning beyond those resulting from disease and mortality.     

On Being Poor and Feeling Poor: Low Socioeconomic Status and the Moral Self

Persons of low socioeconomic status generallyexperience worse health and shorter lives thantheir better off counterparts. They alsosuffer a greater incidence of adversepsychosocial characteristics, such as lowself-esteem, self-efficacy, and self-masteryand increased cynicism and hostility. Thesepopulation data suggest another category ofharm to persons: diminished moral agency. Chronic socioeconomic deprivation can createenvironments that undermine the development ofself and capacities constitutive to moralagency – i.e., the capacity forself-determination and crafting a life of one'sown. The harm affects not only the choicesa person makes, but the chooser herself. Thismoral harm is particularly salient in modernWestern societies, especially in the UnitedStates, where success and failure is attributedto the individual, with little notice of thelarger social and political realities thatinform an individual's circumstances and choices.     

Acting Nasty in the Face of Failure? Longitudinal Observations of “Hard-to-Manage” Children Playing a Rigged Competitive Game with a Friend

Peer problems are almost universal among children with disruptive behavior disorders, and have been linked to social information processing deficits that lead to heightened threat responses (K. A. Dodge, 1980). This 2-year longitudinal study uses direct observations to examine the real-life significance of this finding. Forty hard-to-manage children and 40 typically developing control children were filmed at ages 5 and 7 playing a rigged competitive game in which they experienced a clear threat of losing. Group differences in negative behavior (hard-to-manage > controls) were stable over time and independent of verbal ability. Predictors of individual differences in negative behavior were also examined. Previous studies with this sample have shown that at 4 years of age, the hard-to-manage children displayed elevated frequencies of violent pretend play (J. Dunn & C. Hughes, 2001), coupled with poor performance on tests of executive function and theory of mind (C. Hughes, J. Dunn, & A. White, 1998). In this study, 4-year-olds whose pretend play indicated a preoccupation with violence were more likely to respond negatively to the threat of losing a competitive game at age 5 and at age 7. Four-year-olds who performed poorly on tests of theory of mind and executive function showed higher rates of negative behavior at age 5 but not age 7. These findings highlight just a few of the multiple paths leading to peer problems among children with disruptive behavior problems.     

Haitian and Haitian American experiences of racism and socioethnic discrimination in Miami-Dade county: At-risk and court-involved youth

We examine how juvenile justice-involved youth of Haitian descent in Miami-Dade County cope with structural racism and its impact on their mental health. Drawing on longitudinal ethnography, psychosocial assessment data, and a family-based clinical intervention funded by the National Institute on Drug Abuse, this article explores youth narratives of discrimination prior to and during the COVID-19 pandemic. We use critical race theory and theory of practice to understand youths’ perceptions as racialized bodies and stigmatized selves, highlighting the experiences and perspectives of a particular black immigrant group, ethnic beings caught up in the everyday practices of racialization, sociocultural marginalization, and racism. We frame these experiences as a variation of the complex continuum of structural racism and racial domination in the US. These experiences have caused anger, fear, anxiety, chronic anticipatory distress, and hopelessness among youth of Haitian descent. We conclude with some recommendations for therapeutic support that encourages youth to process their experiences, promotes their development of a positive self-concept, and provides them with mind-body techniques to attenuate the physical impacts of discriminatory events. The clinical trial registration number for this study intervention is NCT03876171.     

Views of a good life and allostatic load: Physiological correlates of theories of a good life depend on the socioeconomic context

This research examines the relationship between one’s theory of a good life and allostatic load, a marker of cumulative biological risk, and how this relationship differs by socioeconomic status. Among adults with a bachelor’s degree or higher, those who saw individual characteristics (e.g. personal happiness, effort) as part of a good life had lower levels of allostatic load than those who did not. In contrast, among adults with less than a bachelor’s degree, those who saw supportive relationships as part of a good life had lower levels of allostatic load than those who did not. These findings extend past research on socioeconomic differences in the emphasis on individual or relational factors and suggest that one’s theory of a good life has health implications.     

Knowing that strawberries are red and seeing red strawberries: the interaction between surface colour and colour knowledge information

This study investigates the interaction between surface and colour knowledge information during object recognition. In two different experiments, participants were instructed to decide whether two presented stimuli belonged to the same object identity. On the non-matching trials, we manipulated the shape and colour knowledge information activated by the two stimuli by creating four different stimulus pairs: (1) similar in shape and colour (e.g. TOMATO–APPLE); (2) similar in shape and dissimilar in colour (e.g. TOMATO–COCONUT); (3) dissimilar in shape and similar in colour (e.g. TOMATO–CHILI PEPPER) and (4) dissimilar in both shape and colour (e.g. TOMATO–PEANUT). The object pictures were presented in typical and atypical colours and also in black-and-white. The interaction between surface and colour knowledge showed to be contingent upon shape information: while colour knowledge is more important for recognising structurally similar shaped objects, surface colour is more prominent for recognising structurally dissimilar shaped objects.
