Repeated reminders inrease the speed of memory retrieval by 3‐month‐old infants

In two experiments, we examined the effect of repeated reminder treatments on the speed of memory retrieval by 3‐month‐old human infants. Infants were trained for two consecutive days to kick their feet to produce movement in an overhead mobile. Infants in the one‐reminder condition received a 3 min reminder treatment 13 days after the conclusion of training. Infants in the two‐reminder condition received one 3 min reminder treatment 6 days after the conclusion of training and a second reminder treatment 7 days later (i.e. 13 days following the conclusion of training). Infants in the no‐reminder control condition were not exposed to the reminder prior to the long‐term retention test. In the absence of a reminder treatment, infants exhibited complete forgetting during the long‐term test. Infants exposed to one reminder exhibited retention when tested 24 h after their only reminder, but not when tested earlier. Infants exposed to two reminder treatments, on the other hand, exhibited retention when tested 1, 4 or 24 h after their second reminder treatment. We conclude that the opportunity to retrieve the memory on a prior occasion facilitated subsequent memory retrieval.     

Less exploring by mouth occurs in newborns of depressed mothers

Twenty‐four newborns (M age = 12 days) of depressed and nondepressed mothers were assessed for oral perception of a nubby and smooth texture. Both groups of newborns discriminated between these textures and showed a sucking preference for the smooth texture. However, the newborns of depressed mothers spent 50% less time orally exploring the stimuli, one‐third less time exploring the more novel nubby texture, and 59% less time mouthing the smooth texture. Newborns of depressed mothers may have biological differences that affect their emotional arousal and emotional regulation (e.g., capacity for self‐soothing). © 2000 Michigan Association for Infant Mental Health.     

Collective guilt,moral outrage,and support for helping the poor: A matter of system versus in‐group responsibility framing

We examined how the framing of responsibility for reducing socio‐economic inequality affects individuals' emotional reactions towards the poor and the willingness to engage in prosocial actions. Attribution of responsibility to either the system (government and institutions), the less deprived in‐group, or the disadvantaged out‐group (poor) was measured (Study 1) and manipulated (Study 2). Consistent with our hypotheses, moral outrage was higher than collective guilt when system responsibility for inequalities was put forth, but collective guilt arose to reach the level of moral outrage when in‐group responsibility was emphasized. Moreover, distinguishing between collective guilt for action and for inaction, we found guilt for inaction more difficult and thus less likely to arise, unless responsibility was put on the in‐group. Collective emotions were also found to be negatively linked to system justification motivation illustrating the palliative function of legitimization processes. Finally, moral outrage predicted the willingness to act upon socio‐economic inequalities both when the system's and in‐group's responsibility was emphasized, whereas collective guilt for action (but not for inaction) predicted support for prosocial actions only when the in‐group's responsibility was engaged. These findings suggest that the specific group‐based emotions in response to poverty depend on whether the system or the in‐group is held responsible and differentially predict individuals' commitment to act.     

When Consumers Prefer Bundles with Noncomplementary Items to Bundles with Complementary Items: The Role of Mindset Abstraction

Past research shows that consumers evaluate bundles with complementary items more favorably than they evaluate bundles with noncomplementary items. In a series of four experiments that involve evaluation, willingness to pay, and real choice, we show that this well‐established effect is moderated by the level of mindset abstraction. Complementarity (vs. noncomplementarity) among bundle items prompts relatively concrete (vs. abstract) thinking (study 1). Consequently, consumers evaluate complementary (vs. noncomplementary) bundles more favorably when they think in more concrete (vs. abstract) terms (study 2) or when the consumption context involves lower (vs. higher) spatial (study 3) or temporal (study 4) distance. These effects are mediated by consumers’ heightened sense of “feeling right” during decision making under construal fit (study 4). Finally, the level of complementarity among bundle items differentially influences mental abstraction because of consumers’ tendency to perceive bundles as a single inseparable unit. Therefore, the effect attenuates when consumers adopt a separating—rather than a connecting—mindset (study 3). Overall, this work significantly extends past research on product bundles and offers several managerial implications.     

Under what conditions do U.S. and Taiwanese late adolescents feel victimized by their peers?

This study investigates whether cultural differences exist between the ways U.S. and Taiwanese college students perceive peer victimization using both an experimental vignette method and an open‐ended question format. A total of 1,125 college students (53% female) from the United States (n = 535) and Taiwan (n = 590) read and responded to vignettes which depicted peer interactions in the college context. The peer interactions varied along three factors expected to be associated with differentiating victimization from affiliative teasing: hostility, playfulness, and relationship closeness. Controlling for individual factors of sex, prior victimization, prior teasing, and emphasis on interpersonal harmony, students perceived more victimization when both hostility and a lack of playfulness were present. Culture interacted with the situational factors such that both hostility and lack of playfulness were stronger predictors of perceived victimization for Taiwanese than for U.S. college students. In open‐ended responses about sensitive topics, “Ability and academic performance” and “Self/thoughts/characters/habits” were more indicative of victimization for Taiwanese college students. “Health and disability” was more salient as indicative of victimization for U.S. college students. Findings from this study are among the first to evaluate signals of peer victimization with a cultural comparison; they can be used to inform victimization intervention programs or socioemotional curriculums in late adolescence to be culturally relevant.     

Constructing who can be Japanese: A study of social markers of acceptance in Japan

Social markers of acceptance are socially constructed indicators of adaptation (e.g., language skills or adherence to social norms) that recipient nationals use in deciding whether to view an immigrant as a host community member. This study had two objectives: (a) to distill the markers considered important by Japanese undergraduates to accept immigrants in Japanese society and (b) to test the premises of integrated threat and social identity theories by ascertaining the effects on marker endorsement of perceived immigrant threat, contribution, relative social status, and intergroup permeability. Native‐born Japanese (the term “native‐born Japanese” is used throughout this article to refer to people born as Japanese citizens—differentiating them from immigrants who are Japanese citizens naturalized after birth) from 12 Japanese universities (N = 428) completed an online survey. Marker importance ratings were factor‐analyzed, and three latent dimensions were found representing sociolinguistic, ethnic, and socioeconomic markers. Multiple hierarchical regressions discerned the main effects of immigrants’ perceived threat and contribution on social markers as well as their interactions with intergroup permeability and immigrant relative status. The results underscored perceived threat’s consistent role in increasing marker importance and suggested divergent paths to acceptance: Immigrants perceived as “low‐status” were expected to conform to sociolinguistic and ethnic markers, whereas socioeconomic markers were stressed more for “high‐status” immigrants when perceived immigrant threat increased and intergroup boundaries were considered less permeable.     

Seeking harmony in Chinese families: A dyadic analysis on Chinese parent‒child relations

Based on Leung, Koch, and Lu’s (2002) dualistic harmony model, we examined the relations of two harmony‐seeking behaviors—harmony enhancement and disintegration avoidance—to family functioning among 177 Hong Kong Chinese adolescent?parent dyads. Structural equation modeling results showed that adolescent‐rated harmony enhancement was positively related to adolescent‐rated family functioning whereas parent‐rated harmony enhancement was positively related to parent‐rated family functioning. Disintegration avoidance, however, was not related to family functioning in the two samples. Furthermore, no significant cross‐path association between harmony‐seeking behaviors and family functioning was identified, meaning that the harmony‐seeking behaviors of adolescents and their parents did not relate to each other’s perception of family functioning. Implications of these findings to our understanding of family in Chinese culture are discussed.     

Children's understanding of habitual behaviour

Research into the development of Theory of Mind (ToM) has shown how children from a very early age infer other people's goals. However, human behaviour is sometimes driven not by plans to achieve goals, but by habits, which are formed over long periods of reinforcement. Habitual and goal‐directed behaviours are often aligned with one another but can diverge when the optimal behavioural policy changes without being directly reinforced (thus specifically hobbling the habitual learning strategy). Unlike the flexibility of goal‐directed behaviour, rigid habits can cause agents to persist in behaviour that is no longer adaptive. In the current study, all children predict agents will tend to behave consistently with their goals, but between the ages of 5 and 10, children showed an increasing understanding of how habits can cause agents to persistently take suboptimal actions. These findings stand out from the typical way the development of social reasoning is examined, which instead focuses on children's increasing appreciation of how others' beliefs or expectations affect how they will act in service of their goals. The current findings show that children also learn that under certain circumstances, people's actions are suboptimal despite potentially ‘knowing better.’     

Individual differences in neonatal “imitation” fail to predict early social cognitive behaviour

The influential hypothesis that humans imitate from birth – and that this capacity is foundational to social cognition – is currently being challenged from several angles. Most prominently, the largest and most comprehensive longitudinal study of neonatal imitation to date failed to find evidence that neonates copied any of nine actions at any of four time points (Oostenbroek et al., [2016] Current Biology, 26, 1334–1338). The authors of an alternative and statistically liberal post‐hoc analysis of these same data (Meltzoff et al., [2017] Developmental Science, 21, e12609), however, concluded that the infants actually did imitate one of the nine actions: tongue protrusion. In line with the original intentions of this longitudinal study, we here report on whether individual differences in neonatal “imitation” predict later‐developing social cognitive behaviours. We measured a variety of social cognitive behaviours in a subset of the original sample of infants (N = 71) during the first 18 months: object‐directed imitation, joint attention, synchronous imitation and mirror self‐recognition. Results show that, even using the liberal operationalization, individual scores for neonatal “imitation” of tongue protrusion failed to predict any of the later‐developing social cognitive behaviours. The average Spearman correlation was close to zero, mean r_s = 0.027, 95% CI [?0.020, 0.075], with all Bonferroni adjusted p values > .999. These results run counter to Meltzoff et al.'s rebuttal, and to the existence of a “like me” mechanism in neonates that is foundational to human social cognition.
