Children Expressing Mixed Emotion in a Nonsocial Context

Abstract

Efforts to demonstrate children’s ability to report experiencing mixed emotions have typically used an allocentric approach, asking children to report on emotions of other individuals in response to stories or movie clips demonstrating social themes. In contrast, literature examining children’s personal experiencing and understanding of their own mixed emotions, typified as an egocentric approach, in nonsocial situations remains underdeveloped. The current study examined the development of children’s reported understanding and experience of mixed emotions egocentrically. By examining a nonsocial context, this investigation extends existing gender- and age-related research on expressing egocentric mixed emotion. Using a computerized game with a disappointing wins paradigm, egocentric mixed emotional experience was elicited in 142 children (80 boys, 62 girls) aged 6 to 12?years. Results revealed that age, but not gender, was a statistically significant predictor of expressing egocentric mixed emotion experience and understanding. When studying mixed emotion development in a nonsocial context, gender did not contribute to differences in child reports. A significant positive relationship between egocentric mixed emotion experiencing and understanding also emerged. These findings contribute to our understanding of children’s emotion development and offer future directions for examining the broad domain of nonsocial contexts in youth expression of mixed emotions.     

A discriminated rapid-acquisition laboratory procedure for human continuous choice

Previous continuous choice laboratory procedures for human participants are either prohibitively time-intensive or result in inadequate fits of the generalized matching law (GML). We developed a rapid-acquisition laboratory procedure (Procedure for Rapidly Establishing Steady-State Behavior, or PRESS-B) for studying human continuous choice that reduces participant burden and produces data that is well-described by the GML. To test the procedure, 27 human participants were exposed to 9 independent concurrent random-interval random-interval reinforcement schedules over the course of a single, 37-min session. Fits of the GML to the participants' data accounted for large proportions of variance (median R²: 0.94), with parameter estimates that were similar to those previously found in human continuous choice studies [median a: 0.67; median log(b): -0.02]. In summary, PRESS-B generates human continuous choice behavior in the laboratory that conforms to the GML with limited experimental duration.     

The Effects of Accuracy Motivation on Children's and Adults' Event Recall,Suggestibility, and Their Answers to Unanswerable Questions

This study investigated children's and adults' event recall accuracy and suggestibility effects when participants' accuracy motivation was manipulated. A total of 240 participants (6-, 7-, and 8-year-olds, and adults) were shown a video and later asked 4 types of questions: answerable questions, both open-ended and strongly misleading, and unanswerable questions, both open-ended and strongly misleading. Participants were either (a) rewarded with a token for every correct answer (high accuracy motivation, Free Report Plus Incentive condition), (b) explicitly given the option of answering with "don't know" when unsure (medium accuracy motivation, Free Report condition), or (c) asked to provide an answer to every question, even when they were not sure or had to guess or both (low accuracy motivation, Forced Report condition). The condition with the high accuracy motivation yielded the highest recall accuracy scores for answerable open-ended and misleading questions. For unanswerable questions, even the youngest age group was able to increase the number of appropriate "don't know" answers when highly motivated to be accurate, but a misleading question format undermined these abilities. The results highlight important interactions between social (accuracy motivation) and cognitive factors (metacognitive monitoring processes) in children's formal interviewing.     

Cellular site and molecular mode of synapsin action in associative learning

Synapsin is an evolutionarily conserved, presynaptic vesicular phosphoprotein. Here, we ask where and how synapsin functions in associative behavioral plasticity. Upon loss or reduction of synapsin in a deletion mutant or via RNAi, respectively, Drosophila larvae are impaired in odor-sugar associative learning. Acute global expression of synapsin and local expression in only the mushroom body, a third-order "cortical" brain region, fully restores associative ability in the mutant. No rescue is found by synapsin expression in mushroom body input neurons or by expression excluding the mushroom bodies. On the molecular level, we find that a transgenically expressed synapsin with dysfunctional PKA-consensus sites cannot rescue the defect of the mutant in associative function, thus assigning synapsin as a behaviorally relevant effector of the AC-cAMP-PKA cascade. We therefore suggest that synapsin acts in associative memory trace formation in the mushroom bodies, as a downstream element of AC-cAMP-PKA signaling. These analyses provide a comprehensive chain of explanation from the molecular level to an associative behavioral change.     

Disaffected Pollyannas: The influence of positive affect on salary expectations,turnover, and long‐term satisfaction

Using a longitudinal sample of MBA graduates, the present study investigates why employees who are high in positive affect (PA) sometimes display higher rates of turnover, as well as the consequences of frequent turnover for long‐term satisfaction. Results show that high PA employees had higher salary expectations than other employees, and that the relationship between low salary and frequent turnover in the 4 years following graduation was stronger among employees higher in PA. High PA employees who changed organizations more frequently in the first 4 years following graduation reported lower job satisfaction and lower life satisfaction 8 years into their careers, a trend that was reversed for low PA employees.     

Extent-of-motion thresholds under subject-relative and object-relative conditions

The experiment was designed to discover the threshold extent of motion at medium speeds amounting to 41, 82, and 164 min./sec., and to compare the perception of motion arising from subject-relative displacement with the perception of motion arising from object-relative displacement. Extent thresholds were found while velocity was kept constant. Different groups of ten Ss were used for each displacement velocity, and for each S the extent threshold was twice obtained by the method of constant stimuli, once under subjectrelative and once under object-relative displacement conditions. Sensitivity to brief displacements of a continuously visible target was high; average thresholds ranged from 1.0 to 4.4 min. under the various conditions employed. The thresholds were higher for subject-relative conditions and the slower displacement velocities and lower for objectrelative conditions and faster displacements.     

Procreative liberty, biological connections, and motherhood.

Given the complex and dramatic array of issues currently facing us in reproductive ethics, bioethicists working on the topic might be forgiven feelings of trepidation when they cast their minds toward the next century. Currently, technologies such as artificial insemination by donor (AID), once the source of intense controversy, are used on a routine basis; mainstream newspapers carry advertisements offering "excellent compensation" to ova "donors;" courts are arguing whether women who serve as gestational or "surrogate" mothers have any parental rights; and proposals resurface to jail pregnant women who take street drugs. Sorting out which developments are to be welcomed and which are to be resisted -- and why -- will require us not only to clarify some of our most basic value commitments, but also to reflect on our understanding of concepts, such as motherhood, that we previously had the luxury of thinking obvious. Let me highlight two issues I think we will be forced to confront as we try to navigate the ethics of reproduction into the twenty-first century -- namely, the value of biological connection and the meaning of motherhood.     

Learning in a task of complex auditory streaming and identification

Adult humans were studied for improvements in their ability to segregate natural whole speech in background noise, in 6 test sessions spaced with a very wide range of inter-session interval (ISI) ranging from minutes to weeks apart so as to examine the effect of this parameter on initial (early) and late components of perceptual learning. Improvements were found even with spacings of 3 weeks between the punctate task sessions. All subjects showed similar total learning amounts but there were sex- and ISI-dependent differences in learning patterns, which we indexed by dividing the overall exponentially-decreasing learning pattern into an early phase between the first two sessions and a later phase between the second and sixth sessions. Males tested at all ISIs and females tested at short (2, 5 and 15 min) and long (1–21 days) ISIs showed small amounts of early-phase learning and large amounts of late-phase learning. However, females tested at intermediate (30 min and 1 h) ISIs showed only early learning, i.e., faster learning given that the total learning was the same. This sex- and ISI-specific deviant pattern could be changed to the standard pattern by interposing an overnight interruption that included sleep amongst test sessions. Thus, improvement in this complex auditory streaming and identification task can occur even with very brief and widely-spaced exposure, generally through a standard pattern of slower overall learning, but also through a sex- and ISI-specific deviant pattern of very rapid early learning which can be modulated by interposed delay unlike the standard pattern.     

Five Dimensions of Faith and Spiritually of Older African American Women Transitioning Out of Homelessness

Background Homelessness among older African American women is emerging as a serious social problem. The increasing cost of living, diminishing community resources, and shrinking retirement benefits, as well as reduced social services are resulting in greater numbers of older minority women becoming homeless. Aims This investigation explores the relevance of faith and spirituality to an advocacy assessment designed to help participants resolve issues that operate as barriers to their leaving and staying out of homelessness. Methods A substudy of a larger research and development project was undertaken, in which qualitative interview methods were used to illuminate the role of faith and spirituality resources in the lives of 84 older homeless African American women. Comparative thematic analysis of illustrative cases was undertaken to better understand the role of faith and spirituality in the women’s lives and in how they used faith and spirituality in coping with homelessness. Findings Five dimensions of faith and spirituality, (a) identity and beliefs; (b) affiliation and membership; (c) involvement; (d) practices; and (e) benefits, served as promising resources in understanding life spaces of homeless minority women and identified promising advocacy strategies. Two cases describe the realities of homelessness for older minority women endeavoring to transition out of homelessness and illustrate how faith and spirituality can buffer stress, facilitate coping, and sustain motivation. Conclusions How older homeless African American women use their faith and spiritual resources to cope with demands of homelessness, challenges of transition, and recovery from the multiple traumas resulting from being homeless makes the assessment of faith and spirituality an important part of the advocacy process.
