A 680,000-person megastudy of nudges to encourage vaccination in pharmacies.

Encouraging vaccination is a pressing policy problem. To assess whether text-based reminders can encourage pharmacy vaccination and what kinds of messages work best, we conducted a megastudy. We randomly assigned 689,693 Walmart pharmacy patients to receive one of 22 different text reminders using a variety of different behavioral science principles to nudge flu vaccination or to a business-as-usual control condition that received no messages. We found that the reminder texts that we tested increased pharmacy vaccination rates by an average of 2.0 percentage points, or 6.8%, over a 3-mo follow-up period. The most-effective messages reminded patients that a flu shot was waiting for them and delivered reminders on multiple days. The top-performing intervention included two texts delivered 3 d apart and communicated to patients that a vaccine was "waiting for you." Neither experts nor lay people anticipated that this would be the best-performing treatment, underscoring the value of simultaneously testing many different nudges in a highly powered megastudy.

Pleas for patience from the cumulative future self.

Current selves wield all the power in intertemporal tradeoffs. Although one set of future selves will make similar tradeoffs in the future, another self - who we term the cumulative future self - falls on the receiving end of those dictated decisions. How current selves commune with the cumulative future self determines whether the former heed pleas, from the latter, for patience.

People search for meaning when they approach a new decade in chronological age.

Although humans measure time using a continuous scale, certain numerical ages inspire greater self-reflection than others. Six studies show that adults undertake a search for existential meaning when they approach a new decade in age (e.g., at ages 29, 39, 49, etc.) or imagine entering a new epoch, which leads them to behave in ways that suggest an ongoing or failed search for meaning (e.g., by exercising more vigorously, seeking extramarital affairs, or choosing to end their lives).

Context matters: How macroeconomic forces may alter the reception of negative emotions in art.

Menninghaus et al. offer a comprehensive model to explain why people pursue darker emotions in art, but we believe they underplay the considerable role of situational factors in driving these preferences. In particular, changing mood states are likely to shape artistic preferences, in large part because positive mood states act as a protective buffer against otherwise aversive experiences.

National differences in environmental concern and performance are predicted by country age.

There are obvious economic predictors of ability and willingness to invest in environmental sustainability. Yet, given that environmental decisions represent trade-offs between present sacrifices and uncertain future benefits, psychological factors may also play a role in country-level environmental behavior. Gott's principle suggests that citizens may use perceptions of their country's age to predict its future continuation, with longer pasts predicting longer futures. Using country- and individual-level analyses, we examined whether longer perceived pasts result in longer perceived futures, which in turn motivate concern for continued environmental quality. Study 1 found that older countries scored higher on an environmental performance index, even when the analysis controlled for country-level differences in gross domestic product and governance. Study 2 showed that when the United States was framed as an old country (vs. a young one), participants were willing to donate more money to an environmental organization. The findings suggest that framing a country as a long-standing entity may effectively prompt proenvironmental behavior.

Vividness of the future self predicts delinquency.

The tendency to live in the here and now, and the failure to think through the delayed consequences of behavior, is one of the strongest individual-level correlates of delinquency. We tested the hypothesis that this correlation results from a limited ability to imagine one's self in the future, which leads to opting for immediate gratification. Strengthening the vividness of the future self should therefore reduce involvement in delinquency. We tested and found support for this hypothesis in two studies. In Study 1, compared with participants in a control condition, those who wrote a letter to their future self were less inclined to make delinquent choices. In Study 2, participants who interacted with a realistic digital version of their future, age-progressed self in a virtual environment were less likely than control participants to cheat on a subsequent task.

Beyond stereotypes: Using socioemotional selectivity theory to improve messaging to older adults.

The tremendous heterogeneity in functional and demographic characteristics of the over-65 age group presents challenges to effective marketing and public health communications. Messages grounded on tacit assumptions that older people are frail, incompetent, and needy risk being overlooked by most of the older population; on the other hand, ignoring age-associated vulnerabilities is problematic. We argue that while traditional approaches to market segmentation based on chronological age often fail, reliable age differences in motivation can inform the types of information that older people typically prefer, attend to, and remember. Socioemotional selectivity theory maintains that as future time horizons grow limited - as they typically do with age - emotional goals are prioritized over goals that focus on exploration. As time left becomes more limited, positive messages are remembered better than negative, and products that help people savor the moment are preferred over those that benefit the long-term future. Relatedly, acknowledging individual strengths and personal resilience are likely to be especially appealing to older people.

Having too little or too much time is linked to lower subjective well-being.

Many people living in modern society feel like they do not have enough time and are constantly searching for more. But is having limited discretionary time actually detrimental? And can there be downsides of having too much discretionary time? In two large-scale data sets spanning 35,375 Americans and two experiments, we explore the relationship between the amount of discretionary time individuals have and their subjective well-being. We find and internally replicate a negative quadratic relationship between discretionary time and subjective well-being. These results show that whereas having too little time is indeed linked to lower subjective well-being caused by stress, having more time does not continually translate to greater subjective well-being. Having an abundance of discretionary time is sometimes even linked to lower subjective well-being because of a lacking sense of productivity. In such cases, the negative effect of having too much discretionary time can be attenuated when people spend this time on productive activities.

Meaningful endings and mixed emotions: The double-edged sword of reminiscence on good times.

Meaningful endings lead people to experience mixed emotions, but it is unclear why. We hypothesized that it is in part because meaningful endings lead people to reminisce on good times. In Study 1, college students who took part in our study on their graduation day (vs. a typical day) reported having spent more time that day reminiscing on good times. Moreover, reminiscence on good times partially mediated the effect of graduation on happiness, sadness, and mixed emotions. In Study 2, we asked undergraduates to reminisce on good (vs. ordinary) times from high school and found that reminiscence on good times elicited happiness, sadness, and mixed emotions. In Study 3, we found that reminiscing on good times that were not (vs. were) repeatable elicited especially intense sadness and mixed emotions. Taken together, results indicate that reminiscing on good times, especially good times gone, elicits mixed emotions and that these emotional consequences help explain why meaningful endings elicit mixed emotions.

Company, country, connections: counterfactual origins increase organizational commitment, patriotism, and social investment.

Four studies examined the relationship between counterfactual origins--thoughts about how the beginning of organizations, countries, and social connections might have turned out differently--and increased feelings of commitment to those institutions and connections. Study 1 found that counterfactually reflecting on the origins of one's country increases patriotism. Study 2 extended this finding to organizational commitment and examined the mediating role of poignancy. Study 3 found that counterfactual reflection boosts organizational commitment even beyond the effects of other commitment-enhancing appeals and that perceptions of fate mediate the positive effect of counterfactual origins on commitment. Finally, Study 4 temporally separated the counterfactual manipulation from a behavioral measure of commitment and found that counterfactual reflection predicted whether participants e-mailed social contacts 2 weeks later. The robust relationship between counterfactual origins and commitment was found across a wide range of companies and countries, with undergraduates and M.B.A. students, and for attitudes and behaviors.

A diffusion tensor imaging study of the anterior limb of the internal capsule in schizophrenia.

Frontal-subcortical cognitive and limbic feedback loops modulate higher cognitive functioning. The final step in these feedback loops is the thalamo-cortical projection through the anterior limb of the internal capsule (AL-IC). Using diffusion tensor imaging (DTI), we evaluated abnormalities in the AL-IC fiber tract in schizophrenia. Participants comprised 16 chronic schizophrenia patients and 19 male, normal controls, who were group matched for handedness, age, and parental socioeconomic status, and underwent DTI on a 1.5 Tesla GE system. We measured the diffusion indices, fractional anisotropy (FA), mean diffusivity (MD), radial diffusivity (RD), and axial diffusivity (AD), and manually segmented, based on FA maps, AL-IC volume, normalized for intracranial contents (ICC). The results showed a significant reduction in the ICC-corrected volume of the AL-IC in schizophrenia, but did not show diffusion measure group differences in the AL-IC in FA, MD, RD or AD. In addition, in the schizophrenia patients, AL-IC FA correlated positively with performance on measures of spatial and verbal declarative/episodic memory, and right AL-IC ICC-corrected volume correlated positively with more perseverative responses on the Wisconsin Card Sort Test (WCST). We found a reduction in AL-IC ICC-corrected volume in schizophrenia, without FA, MD, RD or AD group differences, implicating the presence of a structural abnormality in schizophrenia in this subcortical white matter region which contains important cognitive, and limbic feedback pathways that modulate prefrontal cortical function. Despite not demonstrating a group difference in FA, we found that AL-IC FA was a good predictor of spatial and verbal declarative/episodic memory performance in schizophrenia.

When does the present end and the future begin?

Through the process of prospection, people can mentally travel in time to summon in their mind's eye events that have yet to occur. Such depictions of the future often differ than those of the present, as do choices made for these 2 time periods. Conceptually and semantically, this research tradition presupposes a division between the 2: At some point in the progression of time, the present must yield to the future. Still, the field to date has offered little insight by way of defining the division that separates the present from the future. The basic scientific appeal and practical implications of prospection beg 2 related questions: When do people believe that the present ends and the future begins, and do such perceptions affect decision-making? To the first question, perceptions of when the present ends vary across people (Study 1) and are reliable over time (Study 2). To the second, when people believe that the present ends sooner, they are more likely to make future-oriented choices in correlational and experimental contexts, even when controlling for potentially related constructs (Studies 3-5). Finally, we identify a psychological mechanism underlying this relationship: A shorter present is associated with a sharper division from the future (Study 6a), and this sharp division accounts for future-oriented behavior toward both hypothetical (Study 6b) and incentive-compatible (Study 6c) outcomes. This research sheds light on a foundational but unexplored prerequisite for thinking and acting across time. (PsycINFO Database Record (c) 2020 APA, all rights reserved).

The self over time.

People often have difficulty making decisions that maximize well-being over time, and researchers have explored various reasons for why such poor `intertemporal' decision-making may arise. In this article, I review a body of work that has focused on how the relationship between current and future selves may influence judgments and decisions. Namely, I spotlight research suggesting that the future self is often thought of as another person and how feelings about this `other' person impact decisions across domains. I then review two insights gleaned from this research: in order to positively modify long-term decision-making, interventions may wish to focus on (1) strengthening the felt bond between current and future selves, or (2) reducing the subjective pain of sacrifices made by the current self. I close with several questions future research may wish to address.

On the naturalistic relationship between mood and entertainment choice.

People are sensitive to economic conditions, buying more during booms and less during recessions. Across seven studies, the present research examines whether the nature of their purchases also changes as diffuse, prevailing mood states shift from positive during boom periods to negative during recession periods. Existing research shows that people primarily strive to improve negative moods, whereas they are willing to encounter threatening information when they experience positive mood states. Consistent with these patterns, we find that people showed a relative preference for lighter cultural products during relatively negative economic times, and, to a lesser extent, were slightly more open to heavier cultural products during boom periods. According to archival dataset analyses, these effects persisted across comedic cartoons, music, books, and films. In 2 lab experiments, writing about boom versus recession periods changed preferences for lighter versus heavier cultural products. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Creative expertise is associated with transcending the here and now.

Human imagination is bounded. As situations become more distant in time, place, perspective, and likelihood, they also become more difficult to simulate. What underlies the ability to successfully engage in distal simulations? Here we examine the psychological and neural mechanisms underlying distal simulation by studying individuals known for transcending these limits: creative experts. First, 2 behavioral studies establish that creative experts indeed succeed at engaging in vivid distal simulations, compared to less creative individuals. Performance on a traditional measure of creativity (Study 1) and real-world success in creative pursuits (Study 2) corresponded with more vivid distal simulations across temporal, spatial, social, and hypothetical domains. Study 3 used neuroimaging to identify the neural mechanism supporting creative experts' simulation success. Whereas creative experts and controls recruit the same neural mechanism (the medial prefrontal cortex) while simulating common or proximal events, creative experts preferentially engage a distinct neural mechanism (the dorsomedial subsystem of the default network) while simulating distal events. Moreover, creative experts showed greater functional connectivity within this network at rest, suggesting they may be prepared to engage this mechanism, by default. Studying creative expertise provides new insight into the ability to mentally transcend the here and now. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Poignancy: mixed emotional experience in the face of meaningful endings.

The experience of mixed emotions increases with age. Socioemotional selectivity theory suggests that mixed emotions are associated with shifting time horizons. Theoretically, perceived constraints on future time increase appreciation for life, which, in turn, elicits positive emotions such as happiness. Yet, the very same temporal constraints heighten awareness that these positive experiences come to an end, thus yielding mixed emotional states. In 2 studies, the authors examined the link between the awareness of anticipated endings and mixed emotional experience. In Study 1, participants repeatedly imagined being in a meaningful location. Participants in the experimental condition imagined being in the meaningful location for the final time. Only participants who imagined "last times" at meaningful locations experienced more mixed emotions. In Study 2, college seniors reported their emotions on graduation day. Mixed emotions were higher when participants were reminded of the ending that they were experiencing. Findings suggest that poignancy is an emotional experience associated with meaningful endings.

Future self-continuity is associated with improved health and increases exercise behavior.

To the extent that people feel more continuity between their present and future selves, they are more likely to make decisions with the future self in mind. The current studies examined future self-continuity in the context of health. In Study 1, people reported the extent to which they felt similar and connected to their future self; people with more present-future continuity reported having better subjective health across a variety of measures. In Study 2, people were randomly assigned to write a letter to themselves either three months or 20 years into the future; people for whom continuity with the distant future self was enhanced exercised more in the days following the writing task. These findings suggest that future self-continuity promotes adaptive long-term health behavior, suggesting the promise of interventions enhancing future self-continuity. (PsycINFO Database Record

On the relationship between positive and negative affect: Their correlation and their co-occurrence.

Understanding the nature of emotional experience requires understanding the relationship between positive and negative affect. Two particularly important aspects of that relationship are the extent to which positive and negative affect are correlated with one another and the extent to which they co-occur. Some researchers have assumed that weak negative correlations imply greater co-occurrence (i.e., more mixed emotions) than do strong negative correlations, but others have noted that correlations may imply very little about co-occurrence. We investigated the relationship between the correlation between positive and negative affect and co-occurrence. Participants in each of 2 samples provided moment-to-moment happiness and sadness ratings as they watched an evocative film and listened to music. Results indicated (a) that 4 measures of the correlation between positive and negative affect were quite highly related to 1 another; (b) that the strength of the correlation between measures of mixed emotions varied considerably; (c) that correlational measures were generally (but not always) weakly correlated with mixed emotion measures; and (d) that bittersweet stimuli consistently led to elevations in mixed emotion measures but did not consistently weaken the correlation between positive and negative affect. Results highlight that the correlation between positive and negative affect and their co-occurrence are distinct aspects of the relationship between positive and negative affect. Such insight helps clarify the implications of existing work on age-related and cultural differences in emotional experience and sets the stage for greater understanding of the experience of mixed emotions.

Middle and inferior temporal gyrus gray matter volume abnormalities in first-episode schizophrenia: an MRI study.

OBJECTIVE: Magnetic resonance imaging (MRI) studies of schizophrenia reveal temporal lobe structural brain abnormalities in the superior temporal gyrus and the amygdala-hippocampal complex. However, the middle and inferior temporal gyri have received little investigation, especially in first-episode schizophrenia. METHOD: High-spatial-resolution MRI was used to measure gray matter volume in the inferior, middle, and superior temporal gyri in 20 patients with first-episode schizophrenia, 20 patients with first-episode affective psychosis, and 23 healthy comparison subjects. RESULTS: Gray matter volume in the middle temporal gyrus was smaller bilaterally in patients with first-episode schizophrenia than in comparison subjects and in patients with first-episode affective psychosis. Posterior gray matter volume in the inferior temporal gyrus was smaller bilaterally in both patient groups than in comparison subjects. Among the superior, middle, and inferior temporal gyri, the left posterior superior temporal gyrus gray matter in the schizophrenia group had the smallest volume, the greatest percentage difference, and the largest effect size in comparisons with healthy comparison subjects and with affective psychosis patients. CONCLUSIONS: Smaller gray matter volumes in the left and right middle temporal gyri and left posterior superior temporal gyrus were present in schizophrenia but not in affective psychosis at first hospitalization. In contrast, smaller bilateral posterior inferior temporal gyrus gray matter volume is present in both schizophrenia and affective psychosis at first hospitalization. These findings suggest that smaller gray matter volumes in the dorsal temporal lobe (superior and middle temporal gyri) may be specific to schizophrenia, whereas smaller posterior inferior temporal gyrus gray matter volumes may be related to pathology common to both schizophrenia and affective psychosis.
