Abstract: Wynn’s (1992) seminal research reported that infants looked longer at stimuli representing “incorrect” versus “correct” solutions of basic addition and subtraction problems and concluded that infants have innate arithmetical abilities. Since then, infancy researchers have attempted to replicate this effect, yielding mixed findings. The present meta-analysis aimed to systematically compile and synthesize all of the primary replications and extensions of Wynn (1992) that have been conducted to date. The synthesis included 12 studies consisting of 26 independent samples and 550 unique infants. The summary effect, computed using a random-effects model, was statistically significant, d = +0.34, p < .001, suggesting that the phenomenon Wynn originally reported is reliable. Five different tests of publication bias yielded mixed results, suggesting that while a moderate level of publication bias is probable, the summary effect would be positive even after accounting for this issue. Out of the 10 metamoderators tested, none were found to be significant, but most of the moderator subgroups were significantly different from a null effect. Although this meta-analysis provides support for Wynn’s original findings, further research is warranted to understand the underlying mechanisms responsible for infants’ visual preferences for “mathematically incorrect” test stimuli.

Status goods: experimental evidence from platinum credit cards
Bursztyn, Leonardo A.; Ferman, Bruno; Fiorin, Stefano; Kanz, Martin; Rao, Gautam. 2017. Status goods: experimental evidence from platinum credit cards. Policy Research working paper; no. WPS 8064. Washington, D.C.: World Bank Group. http://documents.worldbank.org/curated/en/432691494944222346/Status-goods-experimental-evidence-from-platinum-credit-cards
This paper provides novel evidence on status goods, using a series of field experiments with an Indonesian bank that markets platinum credit cards to high-income customers. In a first experiment, the paper shows that demand for the platinum card greatly exceeds demand for a nondescript control product with identical benefits, suggesting demand for the pure status aspect of the card. Transaction data reveal that platinum cards are more likely to be used in social contexts, implying social image motivations. Combining price variation with information on the use of the card sheds light on the magnitude of the demand for social status. A second experiment provides evidence of positional externalities from the consumption of these status goods. The final experiment shows that increasing self-esteem causally reduces demand for status goods. This suggests that part of the demand for status is psychological in nature, and that social image is a substitute for self-image.

The smartphone and the driver’s cognitive workload: A comparison of Apple, Google, and Microsoft’s intelligent personal assistants
Strayer, D. L., Cooper, J. M., Turrill, J., Coleman, J. R., & Hopman, R. J. (2017). The smartphone and the driver’s cognitive workload: A comparison of Apple, Google, and Microsoft’s intelligent personal assistants. Canadian Journal of Experimental Psychology/Revue canadienne de psychologie expérimentale, 71(2), 93-110. http://dx.doi.org/10.1037/cep0000104
Abstract: The goal of this research was to examine the impact of voice-based interactions using 3 different intelligent personal assistants (Apple’s Siri, Google’s Google Now for Android phones, and Microsoft’s Cortana) on the cognitive workload of the driver. In 2 experiments using an instrumented vehicle on suburban roadways, we measured the cognitive workload of drivers when they used the voice-based features of each smartphone to place a call, select music, or send text messages. Cognitive workload was derived from primary task performance through video analysis, secondary-task performance using the Detection Response Task (DRT), and subjective mental workload. We found that workload was significantly higher than that measured in the single-task drive. There were also systematic differences between the smartphones: The Google system placed lower cognitive demands on the driver than the Apple and Microsoft systems, which did not differ. Video analysis revealed that the difference in mental workload between the smartphones was associated with the number of system errors, the time to complete an action, and the complexity and intuitiveness of the devices. Finally, surprisingly high levels of cognitive workload were observed when drivers were interacting with the devices: “on-task” workload measures did not systematically differ from that associated with a mentally demanding Operation Span (OSPAN) task. The analysis also found residual costs associated using each of the smartphones that took a significant time to dissipate. The data suggest that caution is warranted in the use of smartphone voice-based technology in the vehicle because of the high levels of cognitive workload associated with these interactions

Genetic and environmental sources of individual differences in views on aging
Kornadt, A. E., & Kandler, C. (2017). Genetic and environmental sources of individual differences in views on aging. Psychology and Aging, 32(4), 388-399. http://dx.doi.org/10.1037/pag0000174
Abstract: Views on aging are central psychosocial variables in the aging process, but knowledge about their determinants is still fragmental. Thus, the authors investigated the degree to which genetic and environmental factors contribute to individual differences in various domains of views on aging (wisdom, work, fitness, and family), and whether these variance components vary across ages. They analyzed data from 350 monozygotic and 322 dizygotic twin pairs from the Midlife Development in the U.S. (MIDUS) study, aged 25–74. Individual differences in views on aging were mainly due to individual-specific environmental and genetic effects. However, depending on the domain, genetic and environmental contributions to the variance differed. Furthermore, for some domains, variability was larger for older participants; this was attributable to increases in environmental components. This study extends research on genetic and environmental sources of psychosocial variables and stimulates future studies investigating the etiology of views on aging across the life span.

Investigating the origins of political views: Biases in explanation predict conservative attitudes in children and adults
Investigating the origins of political views: Biases in explanation predict conservative attitudes in children and adults. Larisa Hussak and Andrei Cimpian. Developmental Science, http://internal.psychology.illinois.edu/~acimpian/reprints/HussakCimpian_DevSci.pdf
Abstract: We tested the hypothesis that political attitudes are influenced by an information-processing factor - namely, a bias in the content of everyday explanations. Because many societal phenomena are enormously complex, people's understanding of them often relies on heuristic shortcuts. For instance, when generating explanations for such phenomena (e.g., why does this group have low status?), people often rely on facts that they can retrieve easily from memory - facts that are skewed toward inherent or intrinsic features (e.g., this group is unintelligent). We hypothesized that this bias in the content of heuristic explanations leads to a tendency to (1) view socioeconomic stratification as acceptable and (2) prefer current societal arrangements to alternative ones, two hallmarks of conservative ideology. Moreover, since the inherence bias in explanation is present across development, we expected it to shape children's proto-political judgments as well. Three studies with adults and 4- to 8-year-old children (N = 784) provided support for these predictions: Not only did individual differences in reliance on inherent explanations uniquely predict endorsement of conservative views (particularly the stratification-supporting component; Study 1), but manipulations of this explanatory bias also had downstream consequences for political attitudes in both children and adults (Studies 2 and 3). This work contributes to our understanding of the origins of political attitudes.

http://dx.doi.org/10.1037/edu0000166
Abstract
Research has found that peers influence the academic achievement of children. However, the mechanisms through which peers matter remain underexplored. The present study examined the relationship between peers’ reading skills and children’s own reading skills among 4,215 total second- and third-graders in 294 classrooms across 41 schools. One innovation of the study was the use of social network analysis to directly assess who children reported talking to or seeking help from and whether children who identified peers with stronger reading skills experienced higher reading skills. The results indicated that children on average identified peers with stronger reading skills and the positive association between peer reading skills and children’s own reading achievement was strongest for children with lower initial levels of reading skills. The study has implications for how teachers can leverage the advantages of peers via in-class activities

The costs and benefits of sexual communal motivation for couples coping with vulvodynia
Muise, A., Bergeron, S., Impett, E. A., & Rosen, N. O. (2017). The costs and benefits of sexual communal motivation for couples coping with vulvodynia. Health Psychology, 36(8), 819-827.
http://dx.doi.org/10.1037/hea0000470
Abstract: Objective: Most women with vulvodynia—a prevalent, chronic, vulvovaginal pain condition—engage in intercourse with their partners despite experiencing pain. Their motivation for doing so appears to be interpersonally oriented (e.g., to meet their partners’ sexual needs), but the costs and benefits of such motivations are unknown. We tested whether sexual communal strength (being responsive to a partner’s sexual needs) and unmitigated sexual communion (focusing on a partner’s sexual needs to the exclusion of one’s own needs) were associated with sexual function, and sexual and relationship satisfaction in couples with coping with vulvodynia. Method: In an 8-week daily experience study, 95 women diagnosed with vulvodynia and their partners reported on sexual communal strength, unmitigated sexual communion, sexual function, and sexual and relationship satisfaction on days when sexual activity occurred. Results: On days when women reported higher sexual communal strength, both they and their partners reported greater sexual function and satisfaction, and their partners reported greater relationship satisfaction. When women’s partners reported higher sexual communal strength, both they and the women reported better sexual function, partners reported greater sexual satisfaction, and women reported greater relationship satisfaction. On days when women reported higher unmitigated sexual communion, they reported poorer sexual function and lower sexual satisfaction, and both the women and partners reported lower relationship satisfaction. When women’s partners reported higher unmitigated sexual communion, they reported poorer sexual function. Conclusions: These novel aspects of sexual motivation should be targeted in psychological interventions aimed to improve the sexual and relationship well-being of affected couples.

A large-scale horizontal-vertical illusion produced with small objects separated in depth
Li, Z., & Durgin, F. H. (2017). A large-scale horizontal-vertical illusion produced with small objects separated in depth. Journal of Experimental Psychology: Human Perception and Performance, 43(8), 1473-1479. http://dx.doi.org/10.1037/xhp0000426
Abstract: We conducted two experiments (total N = 81) to investigate the basis for the large-scale horizontal-vertical illusion (HVI), which is typically measured as 15%–20% and has previously been linked to the presence of a ground plane. In a preliminary experiment, vertical rods of similar angular extents that were either large (4.5–7.5 m) and far, or small (0.9–1.5 m) and near, were matched to horizontal extents in a virtual environment by adjustment of horizontal gaps or rods. Large/far objects showed a larger HVI (∼13%) than did small objects (∼7%), as has been shown before, but the horizontal gap normally used to measure the large-scale HVI was not the source of the larger bias. In the second experiment, we found that simply separating the comparison rod in depth from the vertical rod (thus forcing an evaluation of size at a distance) was sufficient to produce a large HVI (17%), even with small rods. The results are interpreted in light of evidence that the large-scale HVI is dependent on ground plane orientation and may be related to differential angular expansion in the visual coding of elevation and azimuth.

http://dx.doi.org/10.1037/str0000036
Abstract: According to Israeli law, citizens aged 20–40 are obligated to fulfill military reserve duty in the Israeli Defense Forces (IDF). Guided by the theory of conservation of resources (COR; Hobfoll, 2001), this study examined the association of resource loss and gain (economic, time, familial, work, and personal resources) with level of reserve combat soldiers’ distress and satisfaction with their service following the termination of their reserve duty. The sample consisted of 139 male Israeli citizens, ages 23–40, serving as reserve soldiers in the IDF. Using an Internet-based questionnaire, prior to the start of their reserve duty (Time 1), the respondents completed questionnaires assessing psychological traits, social support, and psychological distress. Following the reserve service period (Time 2), the respondents completed a short inventory of resource loss and gain related to the service, and assessments of psychological distress and satisfaction with the service. The main results showed that resource loss was higher on average than resource gain and was associated positively with distress and negatively with satisfaction with the service, whereas resource gain was positively associated with satisfaction only. The findings are compatible with COR theory and point to areas in which reserve soldiers could be assisted in fulfilling the task of maintaining national security while simultaneously preserving personal well-being.

The development of real-time stability supports visual working memory performance: Young children’s feature binding can be improved through perceptual structure
Simmering, V. R., & Wood, C. M. (2017). The development of real-time stability supports visual working memory performance: Young children’s feature binding can be improved through perceptual structure. Developmental Psychology, 53(8), 1474-1493.
http://dx.doi.org/10.1037/dev0000358
Abstract: Working memory is a basic cognitive process that predicts higher-level skills. A central question in theories of working memory development is the generality of the mechanisms proposed to explain improvements in performance. Prior theories have been closely tied to particular tasks and/or age groups, limiting their generalizability. The cognitive dynamics theory of visual working memory development has been proposed to overcome this limitation. From this perspective, developmental improvements arise through the coordination of cognitive processes to meet demands of different behavioral tasks. This notion is described as real-time stability, and can be probed through experiments that assess how changing task demands impact children’s performance. The current studies test this account by probing visual working memory for colors and shapes in a change detection task that compares detection of changes to new features versus swaps in color-shape binding. In Experiment 1, 3- to 4-year-old children showed impairments specific to binding swaps, as predicted by decreased real-time stability early in development; 5- to 6-year-old children showed a slight advantage on binding swaps, but 7- to 8-year-old children and adults showed no difference across trial types. Experiment 2 tested the proposed explanation of young children’s binding impairment through added perceptual structure, which supported the stability and precision of feature localization in memory—a process key to detecting binding swaps. This additional structure improved young children’s binding swap detection, but not new-feature detection or adults’ performance. These results provide further evidence for the cognitive dynamics and real-time stability explanation of visual working memory development

http://dx.doi.org/10.1037/dev0000330
Abstract: Wynn’s (1992) seminal research reported that infants looked longer at stimuli representing “incorrect” versus “correct” solutions of basic addition and subtraction problems and concluded that infants have innate arithmetical abilities. Since then, infancy researchers have attempted to replicate this effect, yielding mixed findings. The present meta-analysis aimed to systematically compile and synthesize all of the primary replications and extensions of Wynn (1992) that have been conducted to date. The synthesis included 12 studies consisting of 26 independent samples and 550 unique infants. The summary effect, computed using a random-effects model, was statistically significant, d = +0.34, p < .001, suggesting that the phenomenon Wynn originally reported is reliable. Five different tests of publication bias yielded mixed results, suggesting that while a moderate level of publication bias is probable, the summary effect would be positive even after accounting for this issue. Out of the 10 metamoderators tested, none were found to be significant, but most of the moderator subgroups were significantly different from a null effect. Although this meta-analysis provides support for Wynn’s original findings, further research is warranted to understand the underlying mechanisms responsible for infants’ visual preferences for “mathematically incorrect” test stimuli.

Catching fire and spreading it: A glimpse into displayed entrepreneurial passion in crowdfunding campaigns
Li, J. (J.), Chen, X.-P., Kotha, S., & Fisher, G. (2017). Catching fire and spreading it: A glimpse into displayed entrepreneurial passion in crowdfunding campaigns. Journal of Applied Psychology, 102(7), 1075-1090. http://dx.doi.org/10.1037/apl0000217
Abstract: Crowdfunding is an emerging phenomenon that enables entrepreneurs to solicit financial contributions for new projects from mass audiences. Drawing on the elaboration likelihood model of persuasion and emotional contagion theory, the authors examined the importance of displayed entrepreneurial passion when seeking resources in a crowdfunding context. They proposed that entrepreneurs’ displayed passion in the introductory video for a crowdfunding project increases viewers’ experienced enthusiasm about the project (i.e., passion contagion), which then prompts them to contribute financially and to share campaign information via social-media channels. Such sharing further facilitates campaign success. In addition, the authors proposed that perceived project innovativeness strengthens the positive effect of displayed passion on social-media exposure and the funding amount a project garners. They first tested their hypotheses in 2 studies using a combination of survey and archival data from the world’s 2 most popular crowdfunding platforms: Indiegogo (Study 1) and Kickstarter (Study 2). They then conducted an experiment (Study 3) to validate the proposed passion contagion process, and the effect of displayed entrepreneurial passion at the individual level. Findings from these 3 studies significantly supported their hypotheses. The authors discuss the theoretical and practical implications of their findings.

Robin Hood effects on motivation in math: Family interest moderates the effects of relevance interventions

http://dx.doi.org/10.1037/dev0000337
Abstract: Using a cluster randomized field trial, the present study tested whether 2 relevance interventions affected students’ value beliefs, self-concept, and effort in math differently depending on family background (socioeconomic status, family interest (FI), and parental utility value). Eighty-two classrooms were randomly assigned to either 1 of 2 intervention conditions or a control group. Data from 1,916 students (Mage = 14.62, SDage = 0.47) and their predominantly Caucasian middle-class parents were obtained via separate questionnaires. Multilevel regression analyses with cross-level interactions were used to investigate differential intervention effects on students’ motivational beliefs 6 weeks and 5 months after the intervention. Socioeconomic status, FI, and parental utility values were investigated as moderators of the intervention effects. The intervention conditions were especially effective in promoting students’ utility, attainment, intrinsic value beliefs, and effort 5 months after the intervention for students whose parents reported lower levels of math interest. Furthermore, students whose parents reported low math utility values especially profited in terms of their utility and attainment math values 5 months after the intervention. No systematic differential intervention effects were found for socioeconomic status. These results highlight the effectiveness of relevance interventions in decreasing motivational gaps between students from families with fewer or more motivational resources. Findings point to the substantial importance of motivational family resources, which have been neglected in previous research.

Abstract: Using a cluster randomized field trial, the present study tested whether 2 relevance interventions affected students’ value beliefs, self-concept, and effort in math differently depending on family background (socioeconomic status, family interest (FI), and parental utility value). Eighty-two classrooms were randomly assigned to either 1 of 2 intervention conditions or a control group. Data from 1,916 students (Mage = 14.62, SDage = 0.47) and their predominantly Caucasian middle-class parents were obtained via separate questionnaires. Multilevel regression analyses with cross-level interactions were used to investigate differential intervention effects on students’ motivational beliefs 6 weeks and 5 months after the intervention. Socioeconomic status, FI, and parental utility values were investigated as moderators of the intervention effects. The intervention conditions were especially effective in promoting students’ utility, attainment, intrinsic value beliefs, and effort 5 months after the intervention for students whose parents reported lower levels of math interest. Furthermore, students whose parents reported low math utility values especially profited in terms of their utility and attainment math values 5 months after the intervention. No systematic differential intervention effects were found for socioeconomic status. These results highlight the effectiveness of relevance interventions in decreasing motivational gaps between students from families with fewer or more motivational resources. Findings point to the substantial importance of motivational family resources, which have been neglected in previous research.
