A sham drug improves a demanding prospective memory task

Every day, people rely on prospective memory—our ability to remember to perform a future action—to carry out myriad tasks. We examined how a sham cognitive enhancing drug might improve people's performance on a prospective memory task. We gave some people (but not others) the sham drug, and asked everyone to perform a high-effort prospective memory task. People who received the sham drug performed better on the prospective memory task. They also took longer to perform their ongoing task, suggesting that they increased their effortful monitoring. These results fit with research showing that suggestions can lead people to increase cognitive effort and increase memory performance.     

ABOLISHING AND ESTABLISHING OPERATION ANALYSES OF SOCIAL ATTENTION AS POSITIVE REINFORCEMENT FOR PROBLEM BEHAVIOR

Three participants whose problem behavior was maintained by contingent attention were exposed to 45‐min presessions in which attention was withheld, provided on a fixed‐time (FT) 15‐s schedule, or provided on an FT 120‐s schedule. Following each presession, participants were then tested in a 15‐min session similar to the social attention condition of an analogue functional analysis. The results showed establishing operation conditions increased problem behavior during tests and that abolishing operation conditions decreased problem behavior during tests.     

Stable individual differences in number discrimination in infancy

Previous studies have shown that as a group 6-month-old infants successfully discriminate numerical changes when the values differ by at least a 1:2 ratio but fail at a 2:3 ratio (e.g. 8 vs. 16 but not 8 vs. 12). However, no studies have yet examined individual differences in number discrimination in infancy. Using a novel numerical change detection paradigm, we present more direct evidence that infants' numerical perception is ratio-dependent even within the range of discriminable ratios and thus adheres to Weber's Law. Furthermore, we show that infants' numerical discrimination at 6 months reliably predicts their numerical discrimination abilities but not visual short-term memory at 9 months. Thus, individual differences in numerical discrimination acuity may be stable within the first year of life and provide important avenues for future longitudinal research exploring the relationship between infant numerical discrimination and later developing math achievement.     

Number knows no bounds

Is the approximate representation of large numbers in adult humans bound to a sensory modality or other aspects of the stimulus presentation, or are these non-verbal numerical representations abstract? A recent paper by Barth, Kanwisher and Spelke provides compelling evidence that non-verbal mental magnitudes are modality-independent.     

Incremental Validity of Situational Judgment Tests for Task and Contextual Job Performance

This paper has three goals. First, it responds to calls for additional research on subgroup differences in situational judgment tests. Second, it expands the cumulative knowledge on the incremental validity of situational judgment tests beyond cognitive ability and personality. Third, it examines the validity and incremental validity of various predictors for both task and contextual performance.     

Black Clergy in the 2000 Elections

Using survey data collected on African Methodist Episcopal and Church of God in Christ clergy, this article finds that black clergy are strongly supportive of their roles as community leaders. However, there are differences along denominational lines in terms of how they interpret their role, in their policy preferences, and in their activities both in and out of the pulpit. In total, this study reveals that there is diversity in black clergy attitudes and activities and that there is a need to examine further how these differences affect black political attitudes and activism.     

“Strengthening the Moral Compass”: The Effects of MDMA (“Ecstasy”) Therapy on Moral and Spiritual Development

This paper argues that therapy with the drug MDMA (also known as Ecstasy) can have positive results in pain reduction for post-traumatic stress disorder and can also encourage moral development and the growth of compassion as well as religious and spiritual insight. Today, small-scale drug trials of MDMA are being performed in a highly controlled clinical environment without any spiritual or moral interpretative framework to help the subjects understand their experiences. Such a framework could help patients integrate and find meaning in the intense, traumatic experiences they have undergone. Pastoral counselors, psychologists, and religious professionals might find it useful to explore this form of therapy further.     

Nurturing Environments for Boys and Men of Color with Trauma Exposure

Boys and men of color are exposed to traumatic experiences at significantly higher rates than are other demographic groups. To understand and address the mental and behavioral health effects of trauma, including violent incidents, on this population, we review the literature showing the context for, outcomes of, and potential responses to trauma exposure. We present the existing research about the unique challenges and associated negative outcomes for boys and men of color, as well as identify the gaps in the literature. We present the potential nurturing responses by systems such as schools, law enforcement, and communities to trauma-exposed boys and men of color, and we describe evidence-based programs and practices that directly address trauma. Finally, we argue that, rather than using a deficit model, a model of optimal development can be used to understand how to support and protect boys and men of color through nurturing environments.     

Effects of Response Instructions on Faking a Situational Judgment Test

A situational judgment test (SJT) and a Big 5 personality test were administered to 203 participants under instructions to respond honestly and to fake good using a within‐subjects design. Participants indicated both the best and worst response (i.e., Knowledge) and the most likely and least likely response (i.e., Behavioral Tendency) to each situation. Faking effect size for the SJT Behavioral Tendency response format was (d=.34) when participants responded first under honest instructions and (d=.15) when they responded first under faking instructions. Those for the Big 5 dimensions ranged from d=.26 to d=1.0. For the Knowledge response format results were inconsistent. Honest condition Knowledge SJT scores were more highly correlated with cognitive ability (r=.56) than were Behavioral Tendency SJT scores (r=.38). Implications for researchers and practitioners are discussed.
