Preschool children favor copying a successful individual over an unsuccessful group

The human aptitude for imitation and social learning underpins our advanced cultural practices. While social learning is a valuable evolutionary survival strategy, blind copying does not necessarily facilitate survival. Copying from the majority allows individuals to make rapid judgments on the value of a trait, based on its frequency. This is known as the majority bias: an individual's tendency to copy the behavior elicited by the largest number of individuals in a population. An alternative approach is to follow those who are the most proficient. While there is evidence that children do show both processes, no study has directly pitted them against each other. To do this, in the current experiment 36 children aged between 4 and 5 years watched live actors demonstrate, as a group or individually, how to open novel puzzle boxes. Children exhibited a bias to the majority when group and individual methods were successful, but favored the individual if the group method was unsuccessful. Affiliating children with the unsuccessful majority group did not impact on this pattern.     

On the (non)persuasive power of a brain image

The persuasive power of brain images has captivated scholars in many disciplines. Like others, we too were intrigued by the finding that a brain image makes accompanying information more credible (McCabe & Castel in Cognition 107:343-352, 2008). But when our attempts to build on this effect failed, we instead ran a series of systematic replications of the original study—comprising 10 experiments and nearly 2,000 subjects. When we combined the original data with ours in a meta-analysis, we arrived at a more precise estimate of the effect, determining that a brain image exerted little to no influence. The persistent meme of the influential brain image should be viewed with a critical eye.     

Rayo’s Metametaphysics

Abstract

In his important book The Construction of Logical Space (Oxford: Oxford University Press, 2013), Agustín Rayo lays out a distinctive metametaphysical view and applies it fruitfully to disputes concerning ontology and concerning modality. In this article, I present a number of criticisms of the view developed, mostly focusing on the underlying metametaphysics and Rayo’s claims on its behalf.     

Reply to critics

ABSTRACT

In this reply to critics, I reply to Stephanie Leary’s, Kris McDaniel’s, Tristram McPherson’s and David Plunkett’s articles on my book Choosing Normative Concepts. One central theme in the replies concerns what is the best strategy for the so-called ardent realist when it comes to responding to the challenge I present in the book. Another central theme concerns the criticisms of my characterizations of what normative concepts and normative properties are.     

Pentecostal theology of mission in the making

While Pentecostals are known for productive and widespread mission work, theological reflection has not kept up with praxis. In recent years, however, a number of leading Pentecostal theologians have started to reflect on key issues such as what are the underlying motifs and distinguishing features as well as urgent challenges facing Pentecostal mission, social concern and relation to other religions, among others. This essays attempts to offer a state‐of‐art critical survey based on English speaking literature at the international level.     

Role clarity,role conflict,and vitality at work: The role of the basic needs

This study aimed to provide new information on the relationships between vitality at work and role clarity, role conflict, and psychological basic need satisfaction. Participants of the cross‐sectional study were 110 employees in a preventive intervention program. Associations between the focal constructs were examined with regression and bootstrapping analyses. The results suggest that the role clarity is associated with subjective vitality at work through higher autonomy and higher competence, and that role conflict is negatively associated with subjective vitality at work through lower autonomy and lower relatedness. Additionally, an interaction between the role characteristics was observed, suggesting that the strength of the association between role clarity and competence, and the strength of the indirect association between role clarity and vitality through competence may vary depending on the level of role conflict. The findings are consistent with the notion that that managers and co‐workers may affect the opportunities of individuals to achieve need satisfaction and feel energized by delineating and negotiating role‐related factors at work. Need satisfaction, in turn, is an antecedent of well‐being and motivation. Employees should feel able to clarify role ambiguities with their supervisor or co‐workers and thus reduce the role conflicts imposed by the expectations of various stakeholders. Limitations of the study include the self‐rating methodology, cross‐sectional design, and properties of the sample restricting generalizability.     

Mission in Pentecostal Theology

The purpose of this essay is to seek to discern as accurately as possible some key theological resources and impulses that stand behind global Pentecostal mission, whose tremendous growth has caught the attention of scholars and practitioners alike. After outlining a profile of key factors believed to be behind missionary enthusiasm and discerning the current state of the emerging Pentecostal missiological scholarship, the essay seeks to provide a fairly comprehensive theological analysis of leading motifs. The essay suggests that the following theological themes undergird Pentecostal missiology, namely a keen eschatological expectation, the pursuit of a distinctively Pentecostal “Full Gospel,” the vision of a holistic salvation, and the reliance on the power and energies of the Holy Spirit. Since Pentecostal theological analysis is still in the making, the current writing should be considered as an interim report.

Nausea During Pregnancy: Relation to Early Childhood Temperament and Behavior Problems at Twelve Years

Associations between maternal nausea during pregnancy and child behavioral outcomes were investigated in a large birth cohort. Generally, 2nd- and 3rd-trimester nausea were more predictive of child outcomes than 1st-trimester nausea. Children whose mothers reported nausea in middle or late pregnancy had lower sensory thresholds and higher levels of activity and emotional intensity in infancy and were reported to be lower in task persistence at age 5. At age 12, these children were viewed by teachers as more careless with their school work and as having more attentional and learning problems.
