Bedding down new words: Sleep promotes the emergence of lexical competition in visual word recognition

Lexical competition processes are widely viewed as the hallmark of visual word recognition, but little is known about the factors that promote their emergence. This study examined for the first time whether sleep may play a role in inducing these effects. A group of 27 participants learned novel written words, such as banara, at 8 am and were tested on their learning at 8 pm the same day (AM group), while 29 participants learned the words at 8 pm and were tested at 8 am the following day (PM group). Both groups were retested after 24 hours. Using a semantic categorization task, we showed that lexical competition effects, as indexed by slowed responses to existing neighbor words such as banana, emerged 12 h later in the PM group who had slept after learning but not in the AM group. After 24 h the competition effects were evident in both groups. These findings have important implications for theories of orthographic learning and broader neurobiological models of memory consolidation.     

Infants’ ability to associate motion paths with object kinds

The goal of the present research was to examine whether infants associate different paths of motion with animate beings and inanimate objects. An infant-controlled habituation procedure was used to examine 10–20-month-old infants’ ability to associate a non-linear motion path (jumping) with animals and a linear (rebounding) motion path with vehicles (Experiment 1) and furniture (Experiment 2). During the habituation phase, infants saw a dog jumping over a barrier and either a vehicle or a piece of furniture rebounding off the barrier. In the test phase, infants looked longer when another inanimate object jumped rather than rebounded, but showed no such differential looking in the case of another animate object. The ability to restrict the animate motion path of jumping to animate beings was present by 10 months of age. The present findings support the hypothesis that motion path is associated with the animate–inanimate distinction early in infancy.     

Perfectionism, Coping, Social Support, and Depression in Maltreated Adolescents

The current study examined the associations among dimensions of perfectionism, coping, social support, and depression in 58 adolescents with a history of maltreatment. Participants completed the Child-Adolescent Perfectionism, multidimensional measures of coping and social support, and the CES-D Depression Scale. Correlational analyses showed that depression was associated with socially prescribed perfectionism, internalized emotion-oriented coping, avoidant-oriented distancing, and low family support and peer support. Analyses of coping responses and perfectionism established links between self-oriented perfectionism and internalized emotion-oriented coping responses and self-reliant problem-solving. Socially prescribed perfectionism was associated with avoidance-oriented coping (i.e., distancing). While self-oriented perfectionism and social support were unrelated, socially prescribed perfectionism was associated with reduced levels of family support. Collectively, the findings highlight the roles of poor coping and social support as contributors to the emotional distress experienced by maltreated adolescents. Moreover, it is suggested that the distress experienced by perfectionistic youth with a history of maltreatment reflects, in part, the role of maladaptive coping styles and coping resource deficits. Our findings support further consideration of personality dimensions such as perfectionism as contributors to poor functioning among maltreated youth.

Psychological Foundations of Financial Planning for Retirement

Little is known about the psychological mechanisms that underlie financial planning for retirement. Most studies of financial planning and investing have used demographic indicators (e.g., age, gender, income) to predict individual differences in saving. In the present study, a model of planning is tested in which psychological indicators (future time perspective, retirement goal clarity, and self-rated financial knowledge) are posited to mediate the relationship between demographic indicators and saving behaviors. Path-analytic techniques were used to test the model, based on data from 265 middle-aged working adults. Analyses revealed substantial support for the role of psychological factors in the retirement planning process. Findings have theoretical implications for the development of psychologically based models of planning, as well as applied implications for those who seek to understand the psychomotivational forces that underlie tendencies to plan and save.

Early Childhood Anxious Solitude and Subsequent Peer Relationships: Maternal and Cognitive Moderators

It was hypothesized that the relation between early anxious solitude and subsequent peer relations would be moderated by early relational (maternal sensitivity) and individual factors (child school readiness). Participants were 1364 children from the National Institute of Child Health and Human Development's Study of Early Child Care and Youth Development. Anxious solitude was assessed by child care providers from 2 to 4.5 years, maternal sensitivity was observed during mother–child interactions from 2 to 4.5 years, school readiness was tested at 3 years, children's interactions with a friend were observed at 4.5 years, and friendship quantity and peer rejection were assessed by first grade teachers. Results indicate that anxious solitary children who had experienced high versus low early maternal sensitivity contributed significantly more actively to positive interaction and less actively to negative interaction with a friend at 4.5 years (these results were contingent on school readiness), and had more friends and were less rejected by peers in first grade. Although high school readiness predicted interactive competency and positive peer relationships in children low in anxious solitude, these benefits were suppressed in anxious solitary children.     

The impact of uncertainty and communal coping on mental health following natural disasters

Feelings of uncertainty are a central feature of the disaster experience. Surprisingly, though, there is very little systematic quantitative research about the impact of uncertainty on disaster survivors. Moreover, communal coping has increasingly received attention as a potential buffer of the negative effects of stressors but that literature is also limited in its application to disasters. This investigation applies research in the domain of uncertainty, together with the Theoretical Model of Communal Coping to better understand the experience of a community exposed to three wildfires in a one year period. A random-digit dialing procedure was used to gather data from 402 individuals. Participants completed measures of mental health, uncertainty, and communal coping in the context of their experience with the most personally stressful of the three wildfires. All analyses were examined separately for those who were evacuated and those who were not. Results support the negative impact of uncertainty across both evacuated and nonevacuated sub-samples and show a strong buffering role for communal coping among those who evacuated. The implications of these findings for the understanding of wildfire survivors' experiences are noted and future directions are proposed.     

A Test of the Testing Effect: Acquiring Problem‐Solving Skills From Worked Examples

The “testing effect” refers to the finding that after an initial study opportunity, testing is more effective for long‐term retention than restudying. The testing effect seems robust and is a finding from the field of cognitive science that has important implications for education. However, it is unclear whether this effect also applies to the acquisition of problem‐solving skills, which is important to establish given the key role problem solving plays in, for instance, math and science education. Worked examples are an effective and efficient way of acquiring problem‐solving skills. Forty students either only studied worked examples (SSSS) or engaged in testing after studying an example by solving an isomorphic problem (STST). Surprisingly, results showed equal performance in both conditions on an immediate retention test after 5 min, but the SSSS condition outperformed the STST condition on a delayed retention test after 1 week. These findings suggest the testing effect might not apply to acquiring problem‐solving skills from worked examples.
