Decision-making competence refers to the ability to make better decisions, as defined by decision-making principles posited by models of rational choice. Historically, psychological research on decision-making has examined how well people follow these principles under carefully manipulated experimental conditions. When individual differences received attention, researchers often assumed that individuals with higher fluid intelligence would perform better. Here, we describe the development and validation of individual-differences measures of decision-making competence. Emerging findings suggest that decision-making competence may tap not only into fluid intelligence but also into motivation, emotion regulation, and experience (or crystallized intelligence). Although fluid intelligence tends to decline with age, older adults may be able to maintain decision-making competence by leveraging age-related improvements in these other skills. We discuss implications for interventions and future research.

Intelligence-as-knowledge in adulthood is influenced by individual differences in intelligence-as-process (i.e., fluid intelligence) and in personality traits that determine when, where, and how people invest their intelligence over time. Here, the relationship between two investment traits (i.e., Openness to Experience and Need for Cognition), intelligence-as-process and intelligence-as-knowledge, as assessed by a battery of crystallized intelligence tests and a new knowledge measure, was examined. The results showed that (1) both investment traits were positively associated with intelligence-as-knowledge; (2) this effect was stronger for Openness to Experience than for Need for Cognition; and (3) associations between investment and intelligence-as-knowledge reduced when adjusting for intelligence-as-process but remained mostly significant.

Abstract Background Research on causal reasoning often uses group-level data analyses that downplay individual differences and simple reasoning problems that are unrepresentative of everyday reasoning. In three empirical studies, we used an individual differences approach to investigate the cognitive processes people used in fault diagnosis, which is a complex diagnostic reasoning task. After first showing how high-level fault diagnosis strategies can be composed of simpler causal inferences, we discussed how two of these strategies—elimination and inference to the best explanation (IBE)—allow normative performance, which minimizes the number of diagnostic tests, whereas backtracking strategies are less efficient. We then investigated whether the use of normative strategies was infrequent and associated with greater fluid intelligence and positive thinking dispositions and whether normative strategies used slow, analytic processing while non-normative strategies used fast, heuristic processing. Results Across three studies and 279 participants, uses of elimination and IBE were infrequent, and most participants used inefficient backtracking strategies. Fluid intelligence positively predicted elimination and IBE use but not backtracking use. Positive thinking dispositions predicted avoidance of backtracking. After classifying participants into groups that consistently used elimination, IBE, and backtracking, we found that participants who used elimination and IBE made fewer, but slower, diagnostic tests compared to backtracking users. Conclusions Participants’ fault diagnosis performance showed wide individual differences. Use of normative strategies was predicted by greater fluid intelligence and more open-minded and engaged thinking dispositions. Elimination and IBE users made the slow, efficient responses typical of analytic processing. Backtracking users made the fast, inefficient responses suggestive of heuristic processing.

Abstract Adherence to health behaviors is often poor, including adherence to at-home technology-based interventions. This study (N=120) explored adherence to a cognitive training intervention delivered via computer tablet, assessed adherence over a 4.5 month period, explored how individual difference factors shaped adherence, and tested the efficacy of message framing manipulations (positive vs. negative framing) in boosting adherence. Individual difference factors predicted adherence, including variations in self-efficacy and belief in the efficacy of cognitive training. Overall message framing had little impact. However, during the final portion of the study in which participants were asked to play as much or as little as they wanted instead of following a schedule, participants who received positively framed messages engaged with the intervention more. Implications for predicting and boosting adherence to home delivered technology-based interventions will be discussed.

Abstract The number of sexual minority (SM) older adults is increasing rapidly, yet this population continues to be underrepresented in research (Fredriksen-Goldsen & Kim, 2017) and experiences significant disparities in health and health care access (Fredriksen-Goldsen, 2016; Wallace et al., 2011). In the current symposium, we analyze data from U.S. national probability samples of middle-aged and older adults (MIDUS, HRS, NESARC-III) to consider how age-related concerns and challenges may be experienced differently by SM individuals compared to their heterosexual counterparts. This symposium includes novel methods and statistical tools, such as daily diary assessments, multilevel modeling, and time-varying effects models. Individual presentations evaluate how: (1) SM women, compared to heterosexual women, may respond differently to menopause through norms and values surrounding womanhood; (2) midlife and older SM individuals use alcohol and cigarettes more frequently across a typical week than their heterosexual counterparts, though their substance use may not be tied to common triggers (e.g., negative mood, stress); (3) despite bisexual older adults reporting more health problems compared to lesbian and gay counterparts, they are less prepared for health concerns and crises (e.g., reporting a lower number of valid wills); and (4) the prevalence of depression and anxiety varies across age, such that older SM adults—especially women—are particularly vulnerable to psychological health problems. These presentations collectively examine complex issues facing older SM adults while emphasizing individual differences (i.e., women’s concerns, bisexual people’s issues). We discuss challenges in researching this growing at-risk population, and we highlight areas of future research and intervention.

From the stance of cognitive developmental theories, claims that general g is an entity of the mind are compatible with notions about domain-general development and age-invariant individual differences. Whether executive function is equated with general g or fluid g, research into the mechanisms by which development occurs is essential to elucidate the kinds of environmental inputs that engender effective intervention.
