A pandemic-related affect gap in risky decisions for self and others.

The early stages of the COVID-19 pandemic exposed large portions of the global populations to increased daily stressors. Research on risky choice in medical contexts suggests that affect-rich choice options promote less-advantageous decision strategies compared with affect-poor options, causing an "affect gap" in decision making. The current experiments (total N = 437, age range: 21-82) sought to test whether negative pandemic-related affect would lower expected-value (EV) maximisation within individuals. In Experiment 1, participants indicated how much they would be willing to pay to avoid specific pandemic experiences (e.g. "not being able to gather in groups"), and then chose among pairs of risky prospects that involved pandemic experiences or subjectively-equivalent monetary losses. EV maximising was lower for pandemic experiences than for equivalent monetary losses. Experiment 2 replicated this finding, and further demonstrated a moderating role of decision perspective. EV maximising was greater in decisions made for another person than in decisions made for oneself. These findings highlight potential strategies for boosting decision making under affect-rich real-world conditions.

Age-Related Differences in Decision-Making: Evidence Accumulation is More Gradual in Older Age.

Older adults tend to exhibit longer response times than younger adults in choice tasks across cognitive domains, such as perception, attention, and memory. The diffusion model has emerged as a standard model for analyzing age differences in choice behavior. Applications of the diffusion model to choice data from younger and older adults indicate that age-related slowing is driven by a more cautious response style and slower non-decisional processes, rather than by age differences in the rate of information accumulation. The Lévy flight model, a new evidence accumulation model that extends the diffusion model, was recently developed to account for differences in response times for correct and error responses. In the Lévy flight model, larger jumps in evidence accumulation can be accommodated compared to the diffusion model. It is currently unknown whether younger and older adults differ with respect to the jumpiness of evidence accumulation. In the current study, younger and older adults (N = 40 per age group) completed a letter-number-discrimination task. Results indicate that older adults show a more gradual (less "jumpy") pattern of evidence accumulation compared to younger adults. Implications for research on cognitive aging are discussed.

Return to work following mild traumatic brain injury: Psychological and cognitive factors in a litigating sample in the post acute stage of recovery.

The purpose of this study was to investigate return to work (RTW) rates following a single uncomplicated mild Traumatic Brain Injury (mTBI) in the post-acute stage in the context of active litigation. More specifically, we sought to determine what psychological and/or cognitive factors predict a RTW after mTBI. Archival data were obtained from a random sample of litigating patients (n = 125; 54% female; mean age: 42.96 (SD = 12.74) who were referred to a private practice for a neuropsychological examination regarding their disability status following a single uncomplicated mTBI. A hierarchical regression analysis was used to assess the predictive value of emotional symptoms and cognition with respect to RTW status. Approximately 50% of the sample did not RTW. Attentional deficits (rs = -0.248) and depressive symptoms (rs = 0.248) were significantly associated with RTW. A hierarchical regression analysis found that depressive symptoms (p < .05) were associated with RTW outcomes. These findings suggest that individuals with increased depressive symptoms are more likely to demonstrate poor RTW outcomes in the post-acute stages of mTBI. These results are of interest to clinicians as they underscore the importance of screening and early intervention for depressive symptoms following a single uncomplicated mTBI in the post-acute stages in litigating samples.

Spiritual Well-Being as a Predictor of Emotional Impairment Following Mild Traumatic Brain Injury.

Traumatic brain injury (TBI) is a leading cause of death and disability, with injuries classified as mild in severity being the most frequently sustained. While the majority of patients recover within 3 months post-injury, many individuals continue to experience debilitating emotional sequelae several months after the injury. While spiritual well-being has been shown to carry protective benefits against both depression and anxiety in the general population, it has not been investigated as a protective factor in this population. The aim of this study was to investigate whether spiritual well-being leads to a reduction in anxious and depressive symptomatology following mild TBI (mTBI). The Beck Anxiety Inventory, Beck Depression Inventory-II, and Spiritual Well-Being Scale were administered to a sample of 83 litigating examinees who had undergone neuropsychological testing to assess their present functioning secondary to mTBI. The existential well-being (EWB) subscale significantly predicted depressive symptomatology. These findings support the role of EWB as contributory factor related to depressive symptomatology following mTBI. Rehabilitation practitioners should consider treatment paradigms that address EWB as a primary contributor to reduce depressive symptomatology, which may ultimately lead to improved functional ability.
