The role of lexical competition and acoustic-phonetic structure in lexical processing: evidence from normal subjects and aphasic patients

This study examined the effects that the acoustic-phonetic structure of a stimulus exerts on the processes by which lexical candidates compete for activation. An auditory lexical decision paradigm was used to investigate whether shortening the VOT of an initial voiceless stop consonant in a real word results in the activation of the lexical-semantic network of its voiced competitor, i.e., does acoustically modified time prime penny via dime. Results for normal subjects showed semantic priming for related pairs and mediated priming for voiced competitors, consistent with cascade models of language processing allowing for interaction between phonological and semantic levels of processing. Although Broca's aphasics showed semantic priming (dime primed penny), they failed to show priming in the context of a lexical competitor. These results are consistent with the hypothesis that these patients have a lexical processing deficit characterized by an overall reduction in lexical activation.     

Savoring with Intent: Investigating Types of and Motives for Responses to Positive Events

To contribute to a growing literature on positive affect (PA) regulation, we report on two studies investigating college students’ responses to hypothetical positive events using a new measure, the Positive Events and Responses Survey (PEARS). The PEARS includes various responses, including savoring (up-regulating PA) and dampening strategies (down-regulating PA), and novel responses (e.g., mass-sharing using Facebook). We examined its convergent and concurrent validity, its relationship with the value of happiness, and motives underlying savoring. Factor analyses supported a 3-factor model: natural savoring (e.g., expressing PA), intentional savoring (e.g., reflecting on the self), and dampening (e.g., minimizing the event). Both natural and intentional savoring were linked to other savoring behaviors, but only natural savoring was linked to perceived savoring ability and (in some bivariate results) to well-being. In contrast, dampening was consistently linked to less savoring and more dampening on other measures, lower well-being, and more depressive symptoms. People reporting valuing happiness more reported higher likelihood of all three types of responses. Qualitative data provided partial support for the hypothesis that intentional savoring strategies are more often used for instrumental reasons (e.g., boosting self-esteem), whereas natural savoring responses may sometimes be more automatic or stem from feeling PA. These studies validate a new measure and suggest that reasons underlying people’s savoring matter.     

A meta‐analytic review of the relationship between emotional dissonance and emotional exhaustion

This meta‐analysis examined the relationship between emotional dissonance and burnout. We collected 57 independent samples that included self‐report measures of emotional dissonance and emotional exhaustion from 16,165 employees. As predicted, a reliable relationship (r = .34) between the two variables was found, indicating that employees who “fake” their emotions at work also suffer from emotional exhaustion, a key component of job burnout. Moderation analyses indicate that effect sizes strengthen as an increasing function of publication year, and are strongest in police work, compared with other service job types. As predicted from a gender role perspective, effect sizes are more pronounced as the percentage of women increases in a sample. Results suggest that emotional dissonance may be added to the growing list of job stressors that lead to emotional exhaustion.     

Selective copying of the majority suggests children are broadly “optimal‐” rather than “over‐” imitators

Human children, in contrast to other species, are frequently cast as prolific “over‐imitators”. However, previous studies of “over‐imitation” have overlooked many important real‐world social dynamics, and may thus provide an inaccurate account of this seemingly puzzling and potentially maladaptive phenomenon. Here we investigate this topic using a cultural evolutionary approach, focusing particularly on the key adaptive learning strategy of majority‐biased copying. Most “over‐imitation” research has been conducted using consistent demonstrations to the observer, but we systematically varied the frequency of demonstrators that 4‐ to 6‐year‐old children observed performing a causally irrelevant action. Children who “over‐imitate” inflexibly should copy the majority regardless of whether the majority solution omits or includes a causally irrelevant action. However, we found that children calibrated their tendency to acquire the majority behavior, such that copying did not extend to majorities that performed irrelevant actions. These results are consistent with a highly functional, adaptive integration of social and causal information, rather than explanations implying unselective copying or causal misunderstanding. This suggests that our species might be better characterized as broadly “optimal‐” rather than “over‐” imitators.     

The Nurturing Program: An Intervention for Parents of Children with Special Needs

Evidence-based psychosocial family interventions enhancing empathy and empowerment are particularly beneficial to families of children who have developmental disabilities. This study assessed the effectiveness of an intervention called the Nurturing Program for Parents and Their Children with Special Needs and Health Challenges (SNHC). Eighty-seven families were enrolled and randomly assigned to a control or treatment group. Forty-six families in the control group received individualized case management (CM) services and forty-one families in the treatment group were assigned to 12 sessions of the SNHC curriculum along with case management services. Before and after the intervention, participants in both conditions completed the Adult and Adolescent Parenting Index-2 assessing parents’ attitudes toward child rearing and the Family Empowerment Scale (FES) measuring family empowerment. Caregivers in the intervention condition improved in empathy towards children’s needs, F(1, 54)?=?4.52, p?=?.04; and all families, both control group and treatment group, improved their attitudes towards the use of corporal punishment by posttest, F(1, 54)?=?6.56, p?=?.013. Also, all caregivers increased in their empowerment over the course of the intervention, F(1, 50)?=?13.28, p?=?.001. Attrition, 22–26% among CM and 51–56% among SNHC+CM, limited generalizability as did participants not completing all SNHC sessions. Despite these limitations, findings suggest that early interventions catering to families of children with developmental disabilities have a positive impact on parenting. To varying degrees, both conditions provided caregivers with tools that positively affected the quality of the parent–child relationships and promoted empowerment.     

Mothers' Ideal Positive Affect Predicts their Socialization of Children's Positive Affect

Parents generally want their children to be happy, but little is known about particular types of positive affect (PA) that parents want their children to experience. Tsai's (2007) affect valuation theory offers a useful framework to understand how parents' emotional goals may shape the socialization of particular types of PA (e.g., excitement vs. relaxation). Participants were 96 mothers and their 7- to 12-year-old children. Results indicated that mothers endorsed similar levels of ideal PA (IPA) for low-, moderate-, and high-arousal PA for both themselves and for their child, suggesting that mothers desire the same type of PA for their children as they want for themselves. In support of the study's main hypothesis, mothers' IPA for their children predicted specific socialization responses that would encourage that type of PA (e.g., mothers' high-arousal IPA predicted greater encouragement of their child to celebrate, whereas mothers' low-arousal IPA predicted encouragement of affection). The findings extend affect valuation theory and emotion socialization research by indicating that parents' emotional goals (i.e., IPA) for their children may contribute to their socialization of children's PA.
