Photographs and the Misinformation Effect: A Boundary Condition of Truthiness
Photographs have been shown to increase “truthiness” across several domains. This study explores the presentation of nonprobative photographs in a misinformation study. A robust replication of the misinformation effect was observed, but photographs did not increase “true” responses in this paradigm, demonstrating a boundary condition for the truthiness effect.

Internal Consistency When Collapsing Different Alcoholic Beverage Types Into One Image Category
In researching valence/arousal of alcohol images, it is unknown whether combining of different alcohol images is appropriate. College students (n=83) participated in a beverage picture viewing task. High internal consistency (alphas > .95 for valence and arousal) supports combining beer, wine, and liquor images in the study of alcohol appetitiveness. Kelsey M. Krueger, Lauri D. Rosario, Randall S. Jorgensen, Stephen A. Maisto Syracuse University

The Influence of Dental Anxiety on Oral Hygiene Practices
The present study explored the effects of dental anxiety on frequency of brushing and flossing. Results indicate that dental anxiety is associated with frequency of flossing but not brushing. Dental professionals may consider implementing anxiety reducing techniques and further emphasize to patients the value of flossing on a daily basis. Michael A. DeDonno Barry University

Investigating the (Neglected) Role of Personality in Testing
Institutional accountability assessments are common in higher education, and most have no personal consequences for students. Importantly, research has shown that in low-stakes testing environments, test-taking motivation is related to test performance (i.e., lower motivation is associated with lower test performance — e.g., Wolf & Smith, 1995). Liu, Bridgeman, and Adler’s (2012) recent work showed that the addition of personal consequences in a low-stakes testing environment increased both students’ test-taking motivation and student’s test performance.
