Presentation and validation of the Radboud Faces Database

Many research fields concerned with the processing of information contained in human faces would benefit from face stimulus sets in which specific facial characteristics are systematically varied while other important picture characteristics are kept constant. Specifically, a face database in which displayed expressions, gaze direction, and head orientation are parametrically varied in a complete factorial design would be highly useful in many research domains. Furthermore, these stimuli should be standardised in several important, technical aspects. The present article presents the freely available Radboud Faces Database offering such a stimulus set, containing both Caucasian adult and children images. This face database is described both procedurally and in terms of content, and a validation study concerning its most important characteristics is presented. In the validation study, all frontal images were rated with respect to the shown facial expression, intensity of expression, clarity of expression, genuineness of expression, attractiveness, and valence. The results show very high recognition of the intended facial expressions.

Effects of dopamine transporter and receptor polymorphisms on smoking cessation in a bupropion clinical trial.

This study examined the role of dopaminergic genes in prospective smoking cessation and response to bupropion treatment in a placebo-controlled clinical trial. Smokers of European ancestry (N=418) provided blood samples for genetic analysis and received either bupropion or placebo (10 weeks) plus counseling. Assessments included the dopamine D2 receptor (DRD2) genotype, dopamine transporter (SLC6A3) genotype, demographic factors, and nicotine dependence. Smoking status was verified at the end of treatment (EOT) and at 6-month follow-up. The results provided evidence for a significant DRD2 * SLC6A3 interaction effect on prolonged smoking abstinence and time to relapse at EOT, independent of treatment condition. Such effects were no longer significant at 6-month follow-up, however. These results provide the first evidence from a prospective clinical trial that genes that alter dopamine function may influence smoking cessation and relapse during the treatment phase.     

“Me”, “We”, and Materialism: Associations between Contingent Self-Worth and Materialistic Values across Cultures

Abstract

Individuals with high levels of externally contingent self-worth tend to base their self-esteem on factors such as appearance, competitive success, and others’ approval. Such tendencies might also elevate people’s focus on material possessions. However, cultural moderation of these associations has yet to be explored. A cross-cultural survey among Chinese and Dutch college students examined the link between externally-based contingent self-worth and materialistic values, as well as the mediating roles of need to belong and need for self-enhancement. An initial multi-group path analysis indicated a stronger link between externally contingent self-worth and materialism for Chinese students than for Dutch students. For both Chinese and Dutch students, externally contingent self-worth was positively related to materialistic values, need to belong, and need for self-enhancement. Need to belong and need for self-enhancement were positively linked with materialism, and need to belong and need for self-enhancement mediated the link between externally contingent self-worth and materialism. Though the indirect effect via self-enhancement was somewhat stronger among Chinese participants, this research demonstrates that people’s externally contingent self-worth might be a factor predicting materialism across cultures, with need to belong and need for self-enhancement playing similar roles as underlying processes in different societies.
