Aging and variety seeking

The authors examined the influence of age on variety seeking in 3 experiments. When given choices among jellybeans or music, age differences in variety seeking emerged. Younger adults selected similar levels of variety when choosing what to consume immediately and what to consume later. In contrast, older adults consistently chose less variety when making choices to be consumed at a later time than when making choices to be consumed immediately. This pattern may be related to an increased focus on regulating future emotional experience that is associated with age.     

Developing Dialogic Argumentation Skills: A 3-year Intervention Study

Argumentation is increasingly recognized as a fundamental intellectual skill, but evidence suggests that few adolescents or adults are skilled arguers. This article reports on an extended (3-year, twice weekly) intervention designed to afford dense practice in dialogic argumentation to middle-school students from traditionally academically disadvantaged backgrounds, with the goal of supporting development of argumentation skills. Students collaborated with peers who shared their positions on a series of social issues, both in small-group argument-building and reflective activities and in electronic dialogues with a succession of opposing-side peers. Annual assessments of individual argumentative skills on new topics showed students gaining in argumentative discourse skills across all 3 years of the intervention. Continued gains during the 3rd year, however, were concentrated among students who began with the least skill, highlighting the potentially equalizing role of such an intervention.     

Privilege and Oppression in Counselor Education: An Intersectionality Framework

Multiculturalism and social justice are considered major forces in the counseling profession, revolutionizing the complexity of social identity, cultural identity, and diversity. Although these major forces have influenced the profession, many challenges exist with their implementation within counselor education curriculum and pedagogy. A major challenge is the complex dynamics of privilege and oppression that both counselor educators and counseling students face. This article discusses the use of intersectionality to approach counselor education pedagogy and practice. El multiculturalismo y la justicia social están considerados como fuerzas importantes con las que la profesión de la consejería está revolucionando la complejidad de la identidad social, la identidad cultural y la diversidad. Aunque estas fuerzas importantes han influido en la profesión, existen desafíos relacionados con su implementación en los planes curriculares y pedagogía de la educación de consejeros. Un desafío significativo es la compleja dinámica entre privilegio y opresión que enfrentan tanto los formadores de consejeros como los estudiantes de consejería. Este artículo discute el uso de la interseccionalidad para enfocar la pedagogía de la educación de consejeros y la práctica.     

Which one made it go? The emergence of diagnostic reasoning in preschoolers

We evaluate the hypothesis that children's diagnostic causal reasoning becomes more sophisticated as their understanding of uncertainty advances. When the causal status of candidate causes was known, 3- and 4-year-olds were capable of diagnostic inference (Experiment 1) and could revise their beliefs when told their initial diagnosis was incorrect (Experiment 2). In Experiments 3 and 4, only 4-year-olds made successful inferences when the causal status of candidate causes was uncertain. The results suggest that by age 3, children appreciate that an effect can have multiple candidate causes, but it is not until age 4 that they begin to reason correctly when the causal status of candidate causes is unknown.     

Functional brain activation to emotional and nonemotional faces in healthy children: Evidence for developmentally undifferentiated amygdala function during the school-age period

The amygdala is a key region in emotion processing. In particular, fMRI studies have demonstrated that the amygdala is active during the viewing of emotional faces. Previous research has consistently found greater amygdala responses to fearful than to neutral faces in adults, convergent with a focus in the animal literature on the amygdala’s role in fear processing. Studies have shown that the amygdala also responds differentially to other facial emotion types in adults. Yet the literature regarding when this differential amygdala responsivity develops is limited and mixed. Thus, the goal of the present study was to examine amygdala responses to emotional and neutral faces in a relatively large sample of healthy school-age children (N?=?52). Although the amygdala was active in response to emotional and neutral faces, the results did not support the hypothesis that the amygdala responds differentially to emotional faces in 7- to 12-year-old children. Nonetheless, amygdala activity was correlated with the severity of subclinical depression symptoms and with emotional regulation skills. Additionally, sex differences were observed in frontal, temporal, and visual regions, as well as effects of pubertal development in visual regions. These findings suggest important differences in amygdala reactivity in childhood.     

The Role of Evidence Diversity and Explanation in 4- and 5-Year-Olds’ Resolution of Counterevidence

Three experiments examined whether 4- and 5-year-olds can explicitly revise uncertain beliefs in light of disconfirming evidence. We considered 2 factors that might influence belief revision: a) the type and variability of evidence provided, and b) whether children generated an explanation of their initial hypothesis. When provided with limited observed evidence, children revised their belief about their initial guess greater than chance expectations, but differences were not observed when the quality of the explanation was considered (Experiment 1). In a similar paradigm, children revised their beliefs more often than chance when asked to explain or describe their initial belief when shown more diverse counterevidence (Experiment 2) or when told that their initial belief was incorrect (Experiment 3). Overall, these data suggest that preschoolers have nascent capacities for explicit belief revision in light of counterevidence.     

Healthy Nests Transition to Parenthood Program: A Mixed-Methods Study

Intimate partner relationship distress is associated with a wide range of negative adult and child outcomes. The transition to parenthood is often a time in the life of a couple where relationship distress increases and satisfaction and intimacy decrease and thus is an ideal time for targeted intervention. The Healthy Nests (HN) intervention is a three-meeting, strength-focused couples intervention for first-time parents designed to decrease maladaptive relationship conflict and increase couple well-being. The authors conducted a mixed-methods exploratory study investigating participants' overall experiences with the HN intervention and measured outcomes associated with relationship satisfaction, help seeking, father involvement, substance use, and depression. A total of 130 parents (65 dyads) participated in a randomized intervention and educational materials–only alternative intervention. Twenty dyads were interviewed as a part of the qualitative portion of the study. While the authors did not find significant quantitative effects on key outcomes, the qualitative findings suggested that participants had a positive experience with the HN intervention and indicated it was useful to have designated time and space to communicate as a couple. Qualitative findings also suggest that the focus on “aspects of strength” and “areas of change” in their relationship was useful. Implications for practice, research, and training are discussed.     

Schemas Mediate the Link Between Procrastination and Depression: Results from the United States and Pakistan

The current study extended the Procrastination-Health model by examining a multiple mediation model, with two cognitive schemas (defectiveness; insufficient self-control) serving as mediators. The models were as follows: procrastination → defectiveness → depression; procrastination → insufficient self-control → depression. Participants included 412 (271 women, 141 men) United States (US) and 240 (107 women, 133 men) Pakistani college students, who responded via self-report questionnaires. In the US sample, results revealed a non-significant direct effect between procrastination and depression after consideration for the two cognitive schemas, suggesting the schemas completely mediated the model. Both defectiveness and insufficient self-control schemas were significant individual mediators. In the Pakistani model, results revealed a significant direct effect and indirect effect through the two cognitive schemas, indicating partial mediation. Only the indirect path through defectiveness schemas was significant in the Pakistani model. Given slight differences in the two models, a moderated-mediation model was analyzed to determine if the strength of the direct and indirect effects varied by nationality. The strength of the direct and indirect effects was not moderated by nationality. Overall, this is the first study to identify cognitive mediators in the procrastination-depression relationship. Such findings represent a significant extension of the Procrastination-Health model and offer some unique cognitive insights into culturally sensitive conceptualizations and treatments for depression.     

Amazon Mechanical Turk in Organizational Psychology: An Evaluation and Practical Recommendations

Purpose

Amazon Mechanical Turk is an increasingly popular data source in the organizational psychology research community. This paper presents an evaluation of MTurk and provides a set of practical recommendations for researchers using MTurk.

Design/Methodology/Approach

We present an evaluation of methodological concerns related to the use of MTurk and potential threats to validity inferences. Based on our evaluation, we also provide a set of recommendations to strengthen validity inferences using MTurk samples.

Findings

Although MTurk samples can overcome some important validity concerns, there are other limitations researchers must consider in light of their research objectives. Researchers should carefully evaluate the appropriateness and quality of MTurk samples based on the different issues we discuss in our evaluation.

Implications

There is not a one-size-fits-all answer to whether MTurk is appropriate for a research study. The answer depends on the research questions and the data collection and analytic procedures adopted. The quality of the data is not defined by the data source per se, but rather the decisions researchers make during the stages of study design, data collection, and data analysis.

Originality/Value

The current paper extends the literature by evaluating MTurk in a more comprehensive manner than in prior reviews. Past review papers focused primarily on internal and external validity, with less attention paid to statistical conclusion and construct validity—which are equally important in making accurate inferences about research findings. This paper also provides a set of practical recommendations in addressing validity concerns when using MTurk.

     

Are pro-social or socially aversive people more physically symmetrical? Symmetry in relation to over 200 personality variables

Symmetry on bilateral body parts indicates evolutionary fitness. Thus, traits positively associated with symmetry are thought to have conferred fitness in evolutionary history. Studies of the relationships between personality traits and symmetry have been narrow and have produced inconsistent findings. In our study, we relate both body symmetry and facial symmetry to 203 personality variables and to the Big Five. Our results demonstrate that (a) symmetry is related to personality traits beyond chance, (b) socially aversive traits, such as aggression and Neuroticism are positively related to symmetry, and (c) pro-social traits such as empathy and Agreeableness are negatively related to symmetry. Such trait levels may developmentally adjust in response to symmetry or may be inherited with symmetry (i.e., dual inheritance).
