Neuropsychological profiles of six children with anoxic brain injury

Anoxic brain injury (ABI) often results in severe memory impairment and other cognitive and behavioral deficits, although limited information is available regarding pediatric cases. This study reported the neuropsychological outcomes in six children and adolescents who sustained ABI. Profiles were compared by mechanism of injury (ischemic vs. hypoxemic) and three cases were evaluated more than once. Severe intellectual, attention, memory, and behavioral impairments were observed in all six cases although academic achievement, internalizing behavioral problems, and visuospatial deficits were in general less severe than other cognitive and behavioral deficits. The longitudinal case studies varied but showed steady increases in memory and intellectual performance in the younger children with strongest improvement in nonverbal abilities and little change in parent-reported behavior. This study raises several possible hypotheses about specific cognitive and behavioral outcomes observed in pediatric ABI.     

Unilateral muscle contractions enhance creative thinking

Following the notion of relative importance of the right hemisphere (RH) in creative thinking, we explored the possibility of enhancing creative problem solving by artificially activating the RH ahead of time using unilateral hand contractions. Participants attempted to complete the Remote Associates Test after squeezing a ball with either their left or right hand. As predicted, participants who contracted their left hand (thus activating the RH) achieved higher scores than those who used their right hand and those who did not contract either hand. Our findings indicate that tilting the hemispheric balance toward the processing mode of one hemisphere by motor activation can greatly influence the outcome of thought processes. Regardless of the specific mechanism involved, this technique has the potential for acting as a therapeutic or remedial manipulation and could have wide applications in aiding individuals with language impairments or other disorders that are believed to be related to hemispheric imbalances.     

Age differences in choice satisfaction: a positivity effect in decision making

The authors tested the possibility that older adults show a positivity effect in decision making, by giving younger and older adults the opportunity to choose 1 of 4 products and by examining the participants' satisfaction with their choice. The authors considered whether requiring participants to explicitly evaluate the options before making a choice has an effect on age differences in choice satisfaction. Older adults in the evaluation condition listed more positive and fewer negative attributes than did younger adults and were more satisfied with their decisions than were younger adults. There were no age differences among those who did not evaluate options. This evaluation-dependent elevation of satisfaction among older adults was still present when participants were contacted 2 weeks after the experiment. Age did not influence the accuracy with which participants predicted how their satisfaction would change over time.     

Individual payments as a longer-term incentive in online panels

Does it pay to pay online panel members? A three-wave longitudinal experiment was conducted with an online panel to examine whether per person payments, paid through an online intermediary, influence response and retention rates. In the payment condition, participants were promised payment for participation at each wave, whereas control participants were not offered any payment. The promise of a payment had a negative effect on response in Wave 1, but a positive effect on response in Wave 2. Payment had no significant effect on retention. Completing a given wave was an indicator for responding to a subsequent invitation.     

Reproductive Technologies of the Self: Michel Foucault and Meta-Narrative-Ethics

This paper presents a direction for narrative ethics based on ethical ideas found in the works of Michel Foucault. Narrative ethics is understood here at the meta-level of cultural discourse to see how the moral subject is constituted by the discursive practices that structure the contemporary debate on reproductive technologies. At this level it becomes meta-narrative-ethics. After a theoretical discussion, this paper uses two literary narratives representing the polarized views in the debate to show how the moral subject may be compelled to relate to its self. Ethics is redefined as Foucauldian rapport à soi, and ethical analysis, at this meta-level, shows how the moral self is intimately connected to cultural discourse.

Suicidality Among Chronically Homeless People with Alcohol Problems Attenuates Following Exposure to Housing First

This study is the first to document suicidality among chronically homeless people with alcohol problems (N = 134) and examine its trajectory following exposure to immediate, permanent, low‐barrier housing (i.e., Housing First). Suicidal ideation, intent, plans, and prior attempts were assessed at baseline and during a 2‐year follow‐up. Baseline suicidal ideation was over four times higher than in the general population. Two‐year, within‐subjects, longitudinal analyses indicated severity of suicidal ideation decreased by 43% from baseline to follow‐up. Significant decreases were also found for intent and clinical significance of ideation. No participants died by suicide during the 2‐year follow‐up.
