T1  - The value of a smile: Facial expression affects ultimatum-game responses
JF  - Judgment and Decision Making
N2  - In social interaction, the facial expression of an opponent contains information that may influence the interaction. We asked whether facial expression affects decision-making in the ultimatum game. In this two-person game, the proposer divides a sum of money into two parts, one for each player, and then the responder decides whether to accept the offer or reject it. Rejection means that neither player gets any money. Results of a large-sample study support our hypothesis that offers from proposers with a smiling facial expression are more often accepted, compared to a neutral facial expression. Moreover, we found lower acceptance rates for offers from proposers with an angry facial expression.

T1  - Does social desirability compromise self-reports of physical activity in web-based research?
JF  - International Journal of Behavioral Nutrition and Physical Activity
N2  - Background: 

This study investigated the relation between social desirability and self-reported physical activity in web-based research. 

Findings: 

A longitudinal study (N = 5,495, 54% women) was conducted on a representative sample of the Dutch population using the Marlowe-Crowne Scale as social desirability measure and the short form of the International Physical Activity Questionnaire. Social desirability was not associated with self-reported physical activity (in MET-minutes/week), nor with its sub-behaviors (i.e., walking, moderate-intensity activity, vigorous-intensity activity, and sedentary behavior). Socio-demographics (i.e., age, sex, income, and education) did not moderate the effect of social desirability on self-reported physical activity and its sub-behaviors. 

Conclusions: 

This study does not throw doubt on the usefulness of the Internet as a medium to collect self-reports on physical activity.
