Retroactive raising of a sensory threshold by a contralateral stimulus

In an experiment designed to extend Howarth and Treisman's recent observations on the lowering of the visual and auditory threshold produced by a warning stimulus, it has been found that the threshold to electrical stimulation of one forearm is raised by a similar stimulus on the other forearm. As in the earlier experiments the “warning” was effective if it came 100 millisec. before or after the threshold stimulus. The effect increased with increasing warning strength over the range of five near-threshold strengths used.

These results appear to be inconsistent with the explanation previously proposed to account for the retroactive lowering of threshold. This suggested that the warning was acting simply as a marker, reducing the subject's uncertainty as to when the stimulus was coming. The fact that the rise in threshold was also induced retroactively shows that some interaction must be occurring in the central processes concerned in perception, and that it cannot be explained in terms of attenuation of the afferent volley.

Exploratory behaviour in elevated and enclosed mazes

Rats given daily exploratory trials in a simple enclosed maze showed a decline in activity from day to day, while animals exploring an elevated maze showed no decline between days. In a further experiment exploration of either an elevated or an enclosed maze was found to cease after about 15 min. The implications of these findings are discussed.     

Exploring the complexities of value creation: The role of engagement strength

Regulatory engagement theory (Higgins, E. T. (2006). Value from hedonic experience and engagement. Psychological Review, 113, 439–460; Higgins, E.T. &; Scholer, A.A. (2009). Engaging the consumer: The science and art of the value creation process. Journal of Consumer Psychology) proposes that engagement strength plays a critical role in the creation of value intensity. We discuss the ways in which engagement, in this model, can be distinguished from arousal, motivation to act, and experienced difficulty. We distinguish between the mechanisms and predictions made by regulatory engagement theory versus cognitive dissonance theory and a goal systems approach. We also describe the complexities and conditions under which some sources of engagement strength (e.g., regulatory fit) may relate to value creation. For instance, while regulatory fit has more typically been associated with increased engagement strength, regulatory nonfit may also sometimes increase engagement by serving as an obstacle to be overcome. We review existing evidence and highlight open questions related to the role of engagement strength in creating value.     

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.     

Counselor Empathy; Religiosity; and Lesbian,Gay, and Bisexual Perspectives

Values-based conflicts, such as between counselor religiosity and ability to work with lesbian, gay, and bisexual (LGB) clients, can present a challenge for counselors and trainees who seek to provide ethical and competent care. Because empathy can facilitate understanding a client's frame of reference, the authors examined the relationships between counselor religiosity, empathy, and LGB perspectives, as well as the potential mediating effects of empathy on values conflicts. The authors discuss implications for counselor education and practice.     

Financial product sensitivity predicts financial health

Recent research has aimed to understand how people consider financial decisions because they have important consequences for well-being. Yet existing research has largely failed to examine how attitudes and behaviors vary as a function of the specific financial product (e.g., debt type). We ask to what extent people differentiate between similarly categorized financial products (e.g., debt or investment) as a function of their terms (e.g., interest costs and expected returns) and whether such differentiation predicts financial health. Across four studies, we find not only that there are individual differences in attitudes toward similar financial products (e.g., two distinct loans), but also that the extent to which a consumer is averse to high-cost versus low-cost products predicts financial health. This relationship cannot be fully explained by financial literacy, numeracy, or intertemporal discounting. In addition, nudging people toward differentiating between financial products promotes decisions that are aligned with financial health.     

Supportive adult relationships and the academic engagement of Latin American immigrant youth

The central aim of this study was to explore the academic engagement trajectories of a sample of recently arrived immigrant students from Latin America. Using an analytic framework that can dynamically model time-sensitive fluctuations (HLM; [Raudenbush, S. W., & Bryk, A. S. (2002). Hierarchicical Linear Models: Applications and Data Analysis Methods (2nd Edition ed.). Thousand Oaks, CA: Sage Publications]), we explored how initial engagement, gender, and support from caring adults at school shaped youths' engagement over time. Students reported a range of engagement trajectories, with gender and support emerging as important predictors of youths' engagement trajectories. Additionally, perceptions of support fluctuated from year to year, and these fluctuations were linked to youths' academic engagement. The findings point to associations between support perceptions and engagement, including links between students' current academic motivation and effort and their current connections with adults. Taken together, the findings present a nuanced portrait of academic engagement and suggest how relationships at school might facilitate positive academic adjustment among Latin American immigrant students over time. Implications for future research, public policy, and practice are discussed.     

Keeping up impressions: Inferential rules for impression change across the Big Five

Not all first impressions have equal longevity. Which kinds of impression have the greatest mobility—downward and upward—over the course of acquaintanceships? In this article, we propose an inferential account of impression maintenance across Big Five trait domains. With data from field and laboratory studies, we provide evidence that positive impressions of agreeableness (A), conscientiousness (C), and emotional stability (ES) are especially vulnerable to small amounts of contrary evidence, whereas positive first impressions of extraversion (E) and openness (O) are more resistant to contrary information. Impressions of E and O demonstrated minimal susceptibility to negativity effects in a longitudinal study of college roommate impressions (Study 1), in a study of perceivers’ implicit theories about different trait domains (Study 2), and in an experimental study of manipulated impression change (Study 3).
