Distinct consolidation outcomes in a visuomotor adaptation task: Off-line leaning and persistent after-effect

Consolidation is a time-dependent process responsible for the storage of information in long-term memory. As such, it plays a crucial role in motor learning. In two experiments, we sought to determine whether one’s performance influences the outcome of the consolidation process. We used a visuomotor adaptation task in which the cursor moved by the participants was rotated 30° clockwise. Thus, participants had to learn a new internal model to compensate for the rotation of the visual feedback. The results indicated that when participants showed good adaptation in the first session, consolidation resulted in a persistent after-effect in a no-rotation transfer test; they had difficulty returning to their normal no-rotation internal model. However, when participants showed poor adaptation in the first session, consolidation led to significant off-line learning (between sessions improvement) but labile after-effects. These observations suggest that distinct consolidation outcomes (off-line learning and persistent after-effect) may occur depending on the learner’s initial performance.

Urban residents' subtle prejudice towards rural‐to‐urban migrants in China: The role of socioeconomic status and adaptation styles

The household registration system (Hukou) implemented by the Chinese government divides the Chinese society into two groups: urban residents and rural residents. Since the 1980s, millions of rural residents have migrated to cities without official permission. In this paper, we investigate urban residents' subtle prejudice towards rural‐to‐urban migrants. Specifically, the impacts of urban residents' socioeconomic status (SES) and their perception of migrants' adaptation styles are examined. A sample including 457 Chinese urban residents is taken from four cities in China. Educational and occupational levels are used to indicate urban residents' SES. Four adaptation styles (integration, assimilation, separation and marginalization) are manipulated by using vignettes. The results show that SES has a negative impact on urban residents' subtle prejudice. This link is further moderated by urban residents' perceptions of migrants' adaptations: the negative effect of SES on subtle prejudice holds only under a perception of integration or assimilation and disappears under a perception of separation or marginalization.

A retrospective longitudinal study of cognitive and language skills in poor reading comprehension

Fifty‐six specific poor reading comprehenders (SPRC) were selected in Grade 4 and retrospectively compared to good comprehenders at preschool (age 5) and at the end of kindergarten, Grade 1, and Grade 2. The results revealed deficits in vocabulary, grammar, verbal memory and early deficits in phonological awareness in most of the SPRC sample, beginning in preschool. The reading comprehension deficits in children with SPRC were not as marked in earlier assessments in Grade 1 and 2, probably because of the greater dependence on word decoding in reading comprehension in the early grades.     

The impact of value-directed remembering on the own-race bias

Learners demonstrate superior recognition of faces of their own race or ethnicity, compared to faces of other races or ethnicities; a finding termed the own-race bias. Accounts of the own-race bias differ on whether the effect reflects acquired expertise with own-race faces or enhanced motivation to individuate own-race faces. Learners have previously been motivated to demonstrate increased recall for highly important items through a value-based paradigm, in which item importance is designated using high (vs. low) point values. Learners receive point values by correctly recalling the corresponding items at test, and are given the goal of achieving a high total point score. In two experiments we examined whether a value-based paradigm can motivate learners to differentiate between other-race faces, reducing or eliminating the own-race bias. In Experiment 1, participants studied own- and other-race faces paired with high or low point values. High point values (12-point) indicated that face was highly important to learn, whereas low point values (1-point) indicated that face was less important to learn. Participants demonstrated increased recognition for high-value own-race (but not other-race) faces, suggesting that motivation alone is not enough to reduce the own-race bias. In Experiment 2, we examined whether participants could use value to enhance recognition when permitted to self-pace their study. Recognition did not differ between high-value own- and other-race faces, reducing the own-race bias. Such data suggest that motivation can influence the own-race bias when participants can control encoding.     

Rebuild or Relocate? Resilience and Postdisaster Decision‐Making After Hurricane Sandy

Hurricane Sandy struck the east coast of the United States on October 29, 2012, devastating communities in its path. In the aftermath, New York implemented a home buyout program designed to facilitate the permanent relocation of residents out of areas considered to be at risk for future hazards. While home buyout programs are becoming popular as policy tools for disaster mitigation, little is known about what factors influence homeowners to participate in or reject these programs. This study used mixed methods to assess the relationship between community resilience and the relocation decision in two heavily damaged communities in which the majority of residents made different decisions regarding whether or not to pursue a buyout. The sample was composed of residents from Oakwood Beach and Rockaway Park, both working‐class communities in New York City, who participated via a community survey (N = 133) and/or in‐depth interviews (N = 28). Results suggested that community resilience moderated the relationship between community of residence and the buyout decision, leading to opposite responses on the buyout decision. Contextual community factors, including the history of natural disasters, local cultural norms, and sense of place, were instrumental in explaining these different responses. Implications for disaster policy are discussed.     

Emergence of amae crying in early infancy as a possible social communication tool between infants and mothers

Amae is defined as “wishing to be loved (Scheidlinger (1999). The Journal of the American Academy of Psychoanalysis, 27(1), p. 91)”. Amae crying is known as crying of infants when seeking intimate emotional communication with caregivers. The objective of this study was to delineate when and how amae crying emerges in early infancy. Crying episodes of four infants were observed bimonthly, in the natural context of their homes, from birth to 6 months of age, for approximately 60 min per session. Crying episodes (total = 275) as determined by two coders were analyzed with respect to several behavioral measures. Results indicated that amae crying emerged at the age of 2 months, and consistently accounted for 30–40% of the total crying episodes after the ages of 3 months. Amae crying could be accurately identified when infants were not in acute discomfort and had already got the attention of their mothers. At such times, infants did not shed tears, cried with a fussy voice, and frequently looked at their mothers. Mothers responded to amae crying more promptly than they did to other types of crying behaviors. It is concluded that 3 months of age, when infants probably begin to use crying as a social communication tool is a major turning point for crying behavior from the perspective of its biological and social roles. It is suggested that amae crying might play an important role in strengthening and encouraging mother–infant interactions.     

Relationship between self-esteem and depressive mood in old age: Results from a six-year longitudinal study

The reciprocal nature of the relationship between depression and personality traits (e.g., self-esteem, neuroticism) is still elusive (e.g., vulnerability and scar models). The aim of this study was to examine the longitudinal reciprocal effects between self-esteem and depressive mood in older adults. 757 participants aged 64–97 years assessed 4 times over a six-year period. Cross-lagged models were estimated using SEM. Our findings showed a relative stability over a six-year period of both self-esteem and depressive mood. There were no cross-lagged reciprocal effects between self-esteem and depressive mood over time, thereby rejecting both vulnerability and scar models. It means that self-esteem and depressive mood do not predate each other in old age. These results suggest a developmental phenomenon in which self-esteem and depressive mood follow two parallel and stable developmental trajectories through old age.     

Private Investigations of White‐Collar Crime Suspicions: A Qualitative Study of the Blame Game Hypothesis

The activity of private investigations by fraud examiners is a business of lawyers, auditors, and other professionals who investigate suspicions of financial crime by white‐collar criminals. This paper presents results from an empirical study of investigation reports. The available sample consists of 28 reports written mostly by auditing firms such as Deloitte, Ernst & Young, and PwC. The blame game can occur at two stages in a private investigation. First, the mandate formulated by a client may point investigators in a specific direction. Next, investigators sometimes suffer from a tunnel view of predetermined opinions. In the sample of 28 investigations reports, more than half of them involve potential blame game victims.
