Assessing team performance: Moderating roles of transactive memory,hypercompetition, and emotional regulation

This study proposes a model based on transactive memory theory to analyze team performance. In the proposed model, team performance is influenced by hypercompetition and emotional regulation directly and indirectly via the mediation of transactive memory and knowledge sharing. According to the model, the direct effect of knowledge sharing on team performance is moderated by both hypercompetition and emotional regulation. Empirical testing of this model, using team personnel in banking, insurance, and financing firms, confirmed the applicability of the transactive memory theory among these service firms’ work teams. Managerial implications and research limitations are discussed.     

Suicide acceptability is related to suicide planning in U.S. adolescents and young adults

The association between adolescents' and young adults' attitudes toward suicide and their own suicidality across five racial-ethnic classifications was studied in a nationally representative sample of 3,301 youth ages 14 to 22 years from the National Annenberg Risk Survey of Youth. Results indicate that adolescents and young adults who most strongly believe that it is acceptable to end one's life are more than fourteen times more likely to make a plan to kill themselves as those who do not have such beliefs (p < .001). Future behavioral prevention and intervention research should take into consideration adolescents' and young adults' approval of suicide as a risk factor for taking their own lives.     

Heart rate variability reflects self-regulatory strength, effort, and fatigue

Experimental research reliably demonstrates that self-regulatory deficits are a consequence of prior self-regulatory effort. However, in naturalistic settings, although people know that they are sometimes vulnerable to saying, eating, or doing the wrong thing, they cannot accurately gauge their capacity to self-regulate at any given time. Because self-regulation and autonomic regulation colocalize in the brain, an autonomic measure, heart rate variability (HRV), could provide an index of self-regulatory strength and activity. During an experimental manipulation of self-regulation (eating carrots or cookies), HRV was elevated during high self-regulatory effort (eat carrots, resist cookies) compared with low self-regulatory effort (eat cookies, resist carrots). The experimental manipulation and higher HRV at baseline independently predicted persistence at a subsequent anagram task. HRV appears to index self-regulatory strength and effort, making it possible to study these phenomena in the field as well as the lab.     

The effects of reinforcer pairing and fading on preschoolers' snack selections

The effects of reinforcement pairing and fading on preschoolers' snack selections were evaluated in a multiple baseline design. Baseline preferences for snack options were assessed via repeated paired-item preference assessments. Edible, social, and activity-based reinforcers were then exclusively paired with a less preferred snack option. Once the snack paired with reinforcement was selected most frequently, the three types of reinforcement were systematically faded. Frequent selections of the previously less preferred snack option were produced with paired reinforcement, but were disrupted for all children as the paired reinforcement was reduced to low levels. These data showed that paired reinforcement was initially effective in increasing preference for the originally less preferred snack options, but more permanent changes in the value of the snack options were not achieved. Conditions for producing persistent changes in children's snack choices are discussed.     

Effects of D-cycloserine on extinction of learned fear to an olfactory cue

D-cycloserine (DCS), a partial NMDA receptor agonist, facilitates extinction of learned fear in rats and has been used to treat anxiety disorders in clinical populations. However, research into the effects of DCS on extinction is still in its infancy, with visual cues being the primary fear-eliciting stimuli under investigation. In both human and animal subjects odors have been found to associate strongly with aversive events. Therefore, this study examined the generality of the effects of DCS on extinction by testing odor cues. Sprague-Dawley rats were conditioned and extinguished to an odor using varying parameters, injected with either saline or DCS (15 mg/kg) following extinction, and then tested for a freezing response 24 h later. Experiment 1 demonstrated that after 3 odor-shock pairings, rats did not display short-term extinction and DCS had no effect on long-term extinction. Experiment 2 demonstrated that after 3 odor-noise pairings, rats displayed significant short-term extinction and DCS significantly facilitated long-term extinction. Following 2 odor-shock pairings in Experiment 3, half the rats displayed short-term extinction ("extinguishers") and half did not ("non-extinguishers"). DCS facilitated long-term extinction in the "extinguishers" condition but not in the "non-extinguishers" condition. In Experiment 4, following 2 odor-shock pairings and an extra extinction session, DCS had a significant facilitatory effect on long-term extinction. Thus, extinction of freezing to an odor cue was facilitated by systemic injections of DCS, but only when some amount of within-session extinction occurred prior to injection.     

Distinct mechanisms in visual category learning

The ways in which visual categories are learned, and in which well-established categories are represented and retrieved, are fundamental issues of cognitive neuroscience. Researchers have typically studied these issues separately, and the transition from the initial phase of category learning to expertise is poorly characterized. The acquisition of novel categories has been shown to depend on the striatum, hippocampus, and prefrontal cortex, whereas visual category expertise has been shown to involve changes in inferior temporal cortex. The goal of the present experiment is to understand the respective roles of these brain regions in the transition from initial learning to expertise when category judgments are being made. Subjects were explicitly trained, over 2 days, to classify realistic faces. Subjects then performed the categorization task during fMRI scanning, as well as a perceptual matching task, in order to characterize how brain regions respond to these faces when not explicitly categorizing them. We found that, during face categorization, face-selective inferotemporal cortex, lateral prefrontal cortex, and dorsal striatum are more responsive to faces near the category boundary, which are most difficult to categorize. In contrast, the hippocampus and left superior frontal sulcus responded most to faces farthest from the category boundary. These dissociable effects suggest that there are several distinct neural mechanisms involved in categorization, and provide a framework for understanding the contribution of each of these brain regions in categorization.     

The relation of cultural context and social relationships to career development in middle school

This study examined the role of supportive relationships (i.e., family, teacher, and peer) and agency (i.e., self-efficacy, motivation, and goal-setting orientation) on three outcomes: academic grades, distress, and career decidedness. Data from 588 middle school youth from Northern (N = 322) and Southern (N = 266) Italy were analyzed using path modeling. Results indicated that across gender and region, agency was consistently related to academic grades and career decidedness. However, the role of supportive relationships was found to differ across gender and region. For both boys from Northern Italy and girls from Southern Italy, the impact of family support on academic grades and career decidedness was mediated by agency. For girls from Northern Italy, family support related directly to academic grades and career decidedness. Implications for practice were described.     

Optimism and College Retention: Mediation by Motivation,Performance, and Adjustment1

Although higher education has been linked to better income, longer life expectancy, and better health, about 25–45% of incoming college freshmen never graduate. The current study examined whether optimistic expectancies are associated with college retention. Participants (N = 2,189) were given surveys when entering college, and academic records were attained after freshman year completion. Dispositional and academic optimism were associated with less chance of dropping out of college, as well as better motivation and adjustment. Academic optimism was also associated with higher grade point average (GPA). Structural equation models revealed that dispositional optimism predicted retention through motivation and adjustment, which in turn predicted retention. Academic optimism, on the other hand, predicted retention through its effect on GPA, motivation, and adjustment.     

Well-being, Happiness and Why Relationships Matter: Evidence from Bangladesh

Although Bangladesh is known as one of the poorest and most densely populated countries in the world, qualitative research and anecdotal evidence suggests its people report levels of happiness that are higher than those found in many other countries. This includes ‘developed’ countries where people have larger per capita incomes and can access a wider range of public services and goods. The paper explores this apparent paradox by analysing primary quantitative and qualitative data, and engaging with existing literature on happiness and objective wellbeing in Bangladesh. The data and analysis presented makes an original and timely contribution to the limited knowledge we have of the construction and experience of happiness and life satisfaction in contexts of extreme and persistent economic poverty. It identifies and offers insights into the ‘personal’ as well as social or ‘relational’ values and goals that people in Bangladesh consider important to achieve happiness in life. It also reflects on how different people experience these values and goals in very different ways. This, we argue, leads to a better understanding of the influence of the social and cultural context in the construction of people’s happiness. In the conclusion, we reflect on the policy implications of our findings.

“Do human values matter for promoting brands on social media? How social media users' values influence valuable brand‐related activities such as sharing,content creation,and reviews”

Companies consider social media‐based consumer engagement behaviors such as sharing, content creation, and reviews for brands as more valuable than “liking” or consuming brand content. Studies show that branded content shared or created by consumers on social media may drive more brand awareness and loyalty than “likes” (Adweek, 2013). Global companies are increasingly focusing their efforts on motivating consumer‐driven content creation (e.g., Coca‐Cola #shareacoke and Apple #ShotoniPhone; Sprout Index, 2018). However, marketing practitioners are only recently beginning to understand social media audiences who engage in such activities (Adweek, 2018). This study posits that human values can be used to identify and segment audiences for social media‐based valuable brand activities. Three online surveys were conducted with Facebook, Twitter, and Instagram users (ages 18–34) on Amazon Mechanical Turk (N = 491). The relationship between social media users' values and their reported social media activities was examined. Findings indicate that the human values examined (conservation, self‐enhancement, openness to change and self‐transcendence) are significant drivers of valuable brand‐related social media activities. Companies should address conservation‐driven users in order to elicit brand sharing and creation activities. Companies should target conservation‐driven users for sharing promotions, self‐enhancement‐driven users for sharing informational content and writing of product reviews, and openness to change‐driven users for user‐generated content. Bussinesses should further highlight their corporate social responsibility efforts as a negative relationship is found between users' self‐transcendence values and brand activities. Recommendations are provided on how brandscan address users' values in their social media marketing to motivate sharing of branded content and content creation.
