What constrains children's learning of novel shape terms?

In this study, 3-year-olds matched on vocabulary score were taught three new shape terms by one of three types of linguistic contrast: corrective, semantic, or referential. A 5-week training paradigm implemented four training sessions and four assessment sessions. Corrective contrast ("This is concave, it is not square," where square is the child's label for the target) produced more learning than did either semantic or referential contrast. In addition, regardless of group, more was learned about those targets that were classified more variably at pretest. Avoidance of lexical overlap (i.e., using more than one term for the same dimension) might make it more difficult for children to learn new dimensional adjectives, and a "shape bias" might make learning shape terms easier. However, children's expectations about the speaker's communicative intent interacted with the potential benefits of contrast in the semantic condition, and children in that group learned no more than did controls.     

How do Relationship Stability and Quality Affect Wellbeing?: Romantic Relationship Trajectories,Depressive Symptoms,and Life Satisfaction across 30 Years

Lifecourse theory scholars focus on how individuals traverse social roles, such as marriage, parenthood, and employment, in similar and different ways across their lives. This study examined one specific role trajectory: romantic relationships. This study examined men’s and women’s (N?=?3617) relationship status and quality across approximately 30 years. Using second-order latent class analysis, results showed four predominant relationship role trajectories: (a) Multiple Transitions, (b) Stable Marriage with High Conflict, (c) Stable Marriage with High Satisfaction, and (d) Marriage to Divorce/cohabitation. These relationship role trajectories differed on two aspects of quality of life: life satisfaction and depressive symptoms. Individuals in the Multiple Transitions trajectory consistently reported poorest quality of life; however, those in the Multiple Transitions and Stable Marriage with High Conflict trajectories were the only that reported decreases in depressive symptoms over 30 years. Relationship satisfaction poorly differentiated the trajectories compared to relationship conflict and stability.     

Does Self-Compassion Protect Adolescents from Stress?

The aim of this study was to determine whether adolescents who were high in self-compassion self-reported different levels of emotional wellbeing than adolescents who were low in self-compassion, and to determine whether those high in self-compassion responded differently under a lab social stressor than those low in self-compassion. In a lab setting, participants (age 13–18; n = 28) completed the Trier Social Stress Test (TSST) and physiological stress was assessed via salivary cortisol, heart rate, blood pressure, and heart rate variability at baseline, during the TSST, and during recovery. After completing the lab protocol, an email was sent to participants that provided a link to an online survey which was composed of emotional wellbeing measures including perceived stress, life satisfaction, positive and negative affect. After conducting repeated measure ANOVAS to determine that the TSST induced a significant stress response, the sample was split at the median of self-compassion. T tests were conducted to determine meaningful differences (Hedges’ g > .20) between the groups. Findings indicated that those in the high self-compassion group (≥the median) self-reported greater emotional wellbeing than those in the low self-compassion group (<the median). Overall, those in the high self-compassion group also had a lower physiologic stress response when exposed to the TSST than those in the low self-compassion group. Regression analyses were also conducted; baseline self-compassion predicted self-reported emotional wellbeing, but did not predict physiological response to the TSST. Findings support the potential buffering effect that self-compassion may have in protecting adolescents from social stressors; yet more research needs to be conducted in larger samples to confirm and replicate these findings.     

Mental rotation: cross-task training and generalization

It is well established that performance on standard mental rotation tasks improves with training (Peters et al., 1995), but thus far there is little consensus regarding the degree of transfer to other tasks which also involve mental rotation. In Experiment 1, we assessed the effect of mental rotation training on participants' Mental Rotation Test (MRT) scores. Twenty-eight participants were randomly assigned to one of three groups: a "One-Day Training," "Spaced Training," or "No Training" group. Participants who received training achieved higher scores on the MRT, an advantage that was still evident after 1 week. Distribution of training did not affect performance. Experiment 2 assessed generalization of mental rotation training to a more complex mental rotation task, laparoscopic surgery. Laparoscopic surgical skills were assessed using Fundamentals of Laparoscopic Surgery (FLS) tasks. Thirty-four participants were randomly assigned to a "Full Mental Rotation Training, MRT and FLS," "MRT and FLS," or "FLS-only" group. MRT results from Experiment 1 were replicated and mental rotation training was found to elicit higher scores on the MRT. Further, mental rotation training was found to generalize to certain laparoscopic surgical tasks. Participants who obtained mental rotation training performed significantly better on mental-rotation dependent surgical tasks than participants who did not receive training. Therefore, surgical training programs can use simple computer or paper-based mental rotation training instead of more expensive materials to enhance certain aspects of surgical performance of trainees.     

What’s in the name? Categorical perception for unfamiliar faces can occur through labeling

The conditions under which categorical perception (CP) occurs for unfamiliar faces are unclear. Although CP is generally found only for familiar faces, it has been reported for unfamiliar faces after brief training (Levin & Beale, 2000) or even without any learning of the original faces (Campanella, Hanoteau, Seron, Joassin, & Bruyer, 2003). Three experiments investigated whether CP can be observed for an unfamiliar morphed face continuum without preexposure to the endpoints of the continuum (Experiment 1); with brief exposure to the endpoints (Experiment 2); or with exposure to named endpoints (Experiment 3). CP was always observed for matched pairs of famous faces. However, CP for unfamiliar faces was induced only when participants observed names paired with the endpoint faces before the start of the experiment. The results suggest that CP effects for unfamiliar faces can be observed extremely rapidly when clear category labels are presented.     

Of Men and Money: Characteristics of Occupations that Affect the Gender Differentiation of Children’s Occupational Interests

Occupational interests become gender differentiated during childhood and remain so among adults. Two characteristics of occupations may contribute to this differentiation: the gender of individuals who typically perform the occupation (workers’ gender) and the particular goals that the occupation allows one to fulfill, such as the opportunity to help others or acquire power (value affordances). Two studies tested hypotheses about whether U.S. 6- to 11-year-olds show gender differences in their interest in novel jobs that were depicted as (a) being performed by men versus women and (b) affording money, power, family, or helping values. In Study 1, 98 children rank-ordered their preferences for experimentally-manipulated novel jobs, and they answered questions about their occupational values and the value affordances of jobs in which men and women typically work. In Study 2, a second sample of 65 children was used to test the replicability of findings from Study 1. As hypothesized, children were more interested in jobs depicted with same- than other-gender workers in both studies. Boys showed greater interest than did girls in novel jobs depicted as affording money in Study 1, but not Study 2. Explicit knowledge that men and women typically work in jobs that afford differing values increased with participants’ age.     

Categorical perception effects reflect differences in typicality on within-category trials

Many studies have shown better discrimination of two stimuli that cross a category boundary than of two stimuli belonging to the same category. This finding, known as categorical perception, is generally assumed to reflect consistently good performance on cross-category trials, relative to within-category trials. However, Roberson, D., Damjanovic, L., and Pilling, M. (Memory & Cognition, 35, 1814-1829, 2007) revealed that performance on within-category pairs of morphed facial expressions matched performance on cross-category trials when the target was a good exemplar of its category. Here, we investigate the generality of that finding by conducting new analyses of data from a series of studies of categorical perception in facial identity and color domains with speakers of different languages. Consistent with Roberson et al. (2007), the new analyses demonstrate that performance for central targets on within-category trials is as good as performance on cross-category trials. Participants perform badly on within-category items only when the target is closer to the category boundary than is the distractor. These results provide no support for the view that categorical perception is associated with increased perceptual sensitivity at category boundaries.     

Examining How Romantic Relationship Quality Influences Individual Psychological Distress Over Time for Men and Women

Poor relationship quality can increase an individual’s psychological distress. There is substantial debate regarding the influence of relationship quality for men and women. Some have found that women’s psychological distress is affected more by poor relationship quality compared to men. Others have found that psychological distress is equally affected for men and women, but it may look different—depressive symptoms for women and total alcohol consumption for men. In this study we examined how men and women differed in changes in relationship quality and changes in psychological distress. Then, we examined how changes in one manifestation of psychological distress and changes in relationship quality were related and how this association differed for men and women. Women reported lower initial relationship quality and total alcohol consumption but higher initial depressive symptoms. Men and women only differed on changes in total alcohol consumption, with women decreasing less than men over 25 years. Finally, both changes in total alcohol consumption and changes in depressive symptoms were related to changes in relationship quality for women, but not men. The reverse direction did not differ by gender, although change in depressive symptoms was related to change in relationship quality. Implications for future research are discussed.     

Participant differentiation of nonclinical fear and anxiety

Participants in four studies rated remembered experiences of fear and anxiety on scales reflecting characteristics postulated to distinguish anxiety from fear. Similarities and differences were found in ratings of the two emotion situations. Some obtained rating contrasts might indicate only quantitative differences, but many were consistent with qualitative distinctions in clinical and theoretical literatures and were interpreted as providing consensual validation for them. While both emotions involved pain, threat, uncertainty, and arousal, anxiety entailed greater future orientation, duration, frequency of occurrence, temporal uncertainty, inhibition, and sensitivity of self-concept to evaluation by self and others. A few rating contrasts appeared to contradict theoretical claims: e.g., noxiousness, helplessness, and response unavailability were greater with fear. It was suggested that some qualitative criteria for differentiating the two emotions are context-sensitive and may interact with a quantitative criterion.
