Counterfactual thinking and facial expressions among Olympic medalists: A conceptual replication of Medvec, Madey, and Gilovich's (1995) findings.

Counterfactual thinking, or contemplation of "what could have been," influences facial expressions of Olympic medalists. Medvec, Madey, and Gilovich (1995) revealed that bronze medalists appeared happier than silver medalists after competition in Olympic events. Two prominent explanations for this phenomenon exist: the formation of (a) category-based counterfactuals and (b) expectation-based counterfactuals. First, Medvec et al. (1995) demonstrated that silver medalists formed an upward comparison to the gold medalist with thoughts of "I almost won Gold" while bronze medalists formed a downward comparison to a fourth place finisher with thoughts of "at least I won a medal." A second explanation suggests that medalists form expectation-based counterfactuals in which silver medalists are more disappointed since their prior expectations for performance were higher than bronze medalists (McGraw, Mellers, & Tetlock, 2005). To test these 2 explanations, we compiled a large dataset of medal stand photographs from the Olympic Multimedia Library and Getty Images for the 2000-2016 Olympic games as well as Sports Illustrated's predictions. Using automated facial expression encoding, we conducted a conceptual replication of prior work and found evidence supporting both category-based and expectation-based counterfactual accounts of Olympic medalists' expressions.

Neural correlates of cognitive reappraisal of positive and negative affect in older adults.

OBJECTIVES: Compromised regulation of negative and positive emotions is a common feature of psychopathology. Healthy aging relates to changes in affective processing, but older adults' regulation of positive affect is less well understood than regulation of negative affect. We examined the cognitive reappraisal of positive and negative affect in healthy younger and older adults, and the neural correlates of reappraisal among older adults. METHOD: Participants viewed negative, positive, and neutral IAPS images and were instructed to attend or reappraise their affective response. Younger and older adults (N = 31) in the behavioral pilot were asked to report on their affect after each image. Another group of older adults (N = 19) completed the same task while undergoing functional magnetic resonance imaging. RESULTS: Behaviorally, older adults were less effective than young adults at downregulating negative and positive affect. Older adults showed engagement of cognitive control regions when regulating negative affect, but not positive affect. Older adults showed increased, rather than decreased, activation in emotion appraisal regions when reappraising negative affect. DISCUSSION: These results may suggest that older adults are less engaged with negative stimuli ; however, future work is needed to address several limitations such as a limited sample size. In addition, we recommend future researchers expand on this work examining regulation of both positive and negative affect among older adults.

Relative Effects of Forward and Backward Planning on Goal Pursuit.

Considerable research has shown that planning plays an important role in goal pursuit. But how does the way people plan affect goal pursuit? Research on this question is scarce. In the current research, we examined how planning the steps required for goal attainment in chronological order (i.e., forward planning) and reverse chronological order (i.e., backward planning) influences individuals' motivation for and perceptions of goal pursuit. Compared with forward planning, backward planning not only led to greater motivation, higher goal expectancy, and less time pressure but also resulted in better goal-relevant performance. We further demonstrated that this motivational effect occurred because backward planning allowed people to think of tasks required to reach their goals more clearly, especially when goals were complex to plan. These findings suggest that the way people plan matters just as much as whether or not they plan.

The Role of the Ventromedial Prefrontal Cortex in Purchase Intent Among Older Adults.

Older adults are frequently the targets of scams and deception, with millions of individuals being affected each year in the United States alone. Previous research has shown that the ventromedial prefrontal cortex (vmPFC) may play a role in vulnerability to fraud. The current study examined brain activation patterns in relation to susceptibility to scams and fraud using functional magnetic resonance imaging (fMRI). Twenty-eight healthy, community-dwelling older adults were subdivided into groups of impaired and unimpaired decision makers as determined by their performance on the Iowa Gambling Task (IGT). While in the scanner, the participants viewed advertisements that were created directly from cases deemed deceptive by the Federal Trade Commission (FTC). We then obtained behavioral measures involving comprehension of claims and purchase intention of the product in each advertisement. Contrasts show brain activity in the vmPFC was less correlated with purchase intention in impaired vs. unimpaired older adult decision makers. Our results have important implications for both future research and recognizing the possible causes of fraud susceptibility among older adults.

Individual differences in the neural signature of subjective value among older adults.

Some healthy older adults show departures from standard decision-making patterns exhibited by younger adults. We asked if such departures are uniform or if heterogeneous aging processes can designate which older adults show differing decision patterns. Thirty-three healthy older adults with varying decision-making patterns on a complex decision task (the Iowa Gambling Task) completed an intertemporal choice task while undergoing functional magnetic resonance imaging. We examined whether value representation in the canonical valuation network differed across older adults based on complex decision-making ability. Older adults with advantageous decision patterns showed increased activity in the valuation network, including the ventromedial prefrontal cortex (VMPFC) and striatum. In contrast, older adults with disadvantageous decision patterns showed reduced or absent activation in the VMPFC and striatum, and these older adults also showed greater blood oxygen level dependent signal temporal variability in the striatum. Our results suggest that a reduced representation of value in the brain, possibly driven by increased neural noise, relates to suboptimal decision-making in a subset of older adults, which could translate to poor decision-making in many aspects of life, including finance, health and long-term care. Understanding the connection between suboptimal decision-making and neural value signals is a step toward mitigating age-related decision-making impairments.

Functional neuroimaging of the Iowa Gambling Task in older adults.

OBJECTIVE: The neural systems most susceptible to age-related decline mirror the systems linked to decision making. Yet, the neural processes underlying decision-making disparities among older adults are not well understood. We sought to identify neural response patterns that distinguish 2 groups of older adults who exhibit divergent decision-making patterns. METHOD: Participants were 31 healthy older adults (ages 59-88, 53% female), defined as advantageous or disadvantageous decision-makers based on Iowa Gambling Task (IGT) performance, who completed an alternate version of the IGT while undergoing functional MRI. The groups were indistinguishable on neuropsychological testing. We contrasted the BOLD signal between groups during 3 phases of the decision-making process: Prechoice (preselection), Prefeedback (postselection), and Feedback (receipt of gains/losses). We further examined whether BOLD signal varied as a function of age in each group. RESULTS: We observed greater activation among the IGT-Disadvantageous relative to -Advantageous older adults in the prefrontal cortex during the early phases of the decision-making process (Prechoice), and in posterior brain regions (e.g., the precuneus) during the later phases (Prefeedback and Feedback). We also found that with increasing age, IGT-Advantageous older adults showed increasing activation in the prefrontal cortex during all phases and increasing activation in the posterior cingulate during earlier phases of the decision process. By contrast, the IGT-Disadvantageous older adults exhibited a reduced or reversed trend. CONCLUSIONS: These functional differences may be a consequence of altered reward processing or differing compensatory strategies between IGT-Disadvantageous and -Advantageous older adults. This supports the notion that divergent neurobiological aging trajectories underlie disparate decision-making patterns.

A magnetoencephalography study of choice bias.

Many factors can influence, or bias, human decision making. A considerable amount of research has investigated the neural correlates of such biases, mostly correlating hemodynamic responses in brain areas with some aspect of the decision. These studies, typically done using functional magnetic resonance imaging or positron emission tomography, have provided useful information about the location of processing in the brain. However, comparatively little research has examined when these processes occur. The present experiment addressed this question by using magnetoencephalography (MEG) to record brain activity while subjects chose preferred options from decision sets. We found that MEG signal deviations for biased decisions occurred as early as 250-750 ms following stimulus onset. Such deviations occurred earliest in sensors over the right anterior cortex. These findings improve our understanding of temporal dynamics of decision biases and suggest ways that existing explanations for this bias could be refined.
