Effect of trait and state approach motivation on aggressive inclinations

Research has suggested that individual differences in behavioral approach sensitivity (BAS) are related to state and trait anger [Carver, C. S. (2004). Negative affects deriving from the behavioral approach system. Emotion, 4, 3–22; Harmon-Jones, E. (2003a). Clarifying the emotive functions of asymmetrical frontal cortical activity. Psychophysiology, 40, 838–848; Harmon-Jones, E. (2003b). Anger and the behavioural approach system. Personality and Individual Differences, 35, 995–1005]. The present research sought to extend this past work by testing whether individual differences in BAS would relate to aggressive inclinations, particularly when approach motivation was situationally primed. Results supported predictions, and thus suggest, contrary to several perspectives (e.g., [Gray, J. A. (1990). Brain systems that mediate both emotion and cognition. Cognition & Emotion, 4(3), 269–288; Watson, D. (2000). Mood and temperament. New York: Guilford Press]), that BAS is involved in more than just positive emotional experiences and behaviors.     

Anxiety symptom focus in sessions of cognitive therapy for depression

The comorbid patient presents an especially difficult problem to a therapist who is attempting to implement a short-term, focused therapy. The current study investigates the effect of comorbid anxiety on cognitive therapy for depression. Participants were a subset of patients (N=24) assigned to the cognitive therapy arm of a large, randomized, controlled trial of treatment for depression. From intake assessments, patients were classified as having low or high levels of comorbid anxiety. Two videotapes of each patient's therapy sessions were coded. Irrespective of intake anxiety level, more time and effort spent addressing anxiety in session was found to predict less improvement in both depression and anxiety symptoms over the course of treatment.     

Appearance-based comments, body dissatisfaction and drive for muscularity in males

This study examined the role of positive and negative appearance-based comments on body dissatisfaction and drive for muscularity among young adult males. The direct and moderating effect of self-esteem were also investigated; and BMI, age, and social desirability were included as covariates. The participants were 214 males aged between 18 and 30 years. More frequent negative comments were associated with higher body dissatisfaction whilst more frequent positive comments were associated with lower body dissatisfaction. However, both frequent negative and positive commentary were associated with higher drive for muscularity. Self-esteem was also associated with both body dissatisfaction and the drive for muscularity, but it did not moderate that influence of either positive or negative messages. Longitudinal research is now needed to determine the directionality of these relationships. Further research is required to establish the contexts in which positive and negative messages are associated with body dissatisfaction and the drive for muscularity.     

Attentional guidance in singleton search: An examination of top-down,bottom-up,and intertrial factors

While it is clear that the goals of an observer change behaviour, their role in the guidance of visual attention has been much debated. In particular, there has been controversy over whether top-down knowledge can influence attentional guidance in search for a singleton item that is already salient by a bottom-up account (Theeuwes, Reimann, & Mortier, 2006). One suggestion is that passive intertrial priming accounts for what has been called top-down guidance (e.g., Maljkovic & Nakayama, 1994). In the present study, participants responded to the shape of a singleton target among homogenous distractors in a trial-by-trial cueing design. We examined the influence of target expectancy, trial history, and target salience (which was manipulated by changing the number of distractors). Top-down influence resulted in fast RTs that were independent of display size, even on trials that received no priming. Our findings show there is a role for top-down guidance, even in singleton search. The designation of intertrial priming as a bottom-up factor, rather than an implicit top-down factor (Wolfe, Butcher, Lee, & Hyle, 2003), is also discussed.     

Study strategies and beliefs about learning as a function of academic achievement and achievement goals

Prior research by Hartwig and Dunlosky [(2012). Study strategies of college students: Are self-testing and scheduling related to achievement? Psychonomic Bulletin &; Review, 19(1), 126–134] has demonstrated that beliefs about learning and study strategies endorsed by students are related to academic achievement: higher performing students tend to choose more effective study strategies and are more aware of the benefits of self-testing. We examined whether students’ achievement goals, independent of academic achievement, predicted beliefs about learning and endorsement of study strategies. We administered Hartwig and Dunlosky’s survey, along with the Achievement Goals Questionnaire [Elliot, A. J., &; McGregor, H. A. (2001). A 2 × 2 achievement goal framework. Journal of Personality &; Social Psychology, 80, 501–519] to a large undergraduate biology course. Similar to results by Hartwig and Dunlosky, we found that high-performing students (relative to low-performing students) were more likely to endorse self-testing, less likely to cram, and more likely to plan a study schedule ahead of time. Independent of achievement, however, achievement goals were stronger predictors of certain study behaviours. In particular, avoidance goals (e.g., fear of failure) coincided with increased use of cramming and the tendency to be driven by impending deadlines. Results suggest that individual differences in student achievement, as well as the underlying reasons for achievement, are important predictors of students’ approaches to studying.     

Willingness to Falsely Take Blame among Friends: Closeness,Reporting Wrongdoing,and Identity

This study examined people’s willingness to falsely take the blame for a friend’s offense. We sought to identify whether friendship closeness and individual differences would predict false blame-taking. Participants were randomly assigned to think of either a close or casual friend engaging in driver negligence and indicated their willingness to falsely take responsibility. Although self-construal was unrelated to willingness, oneness mediated the relationship between friendship closeness and blame-taking willingness. Negative attitudes about reporting wrongdoing predicted a greater willingness, and men were more willing to take the blame than women. Results may help those in the legal system to better identify false confessions.     

Variations in the Gender-Stereotyped Content of Children's Television Cartoons Across Genres

This study examined the gender-stereotyped content of children's TV network cartoons across 4 genres: traditional adventure (e.g., "Spiderman"), nontraditional adventure (e.g., "Reboot"), educational/family (e.g., "Magic School Bus"), and comedy ("Animaniacs"). Acting negatively, showing physical aggression, and being a victim were significantly less likely in the educational/family genre cartoons than any of the other three genres. Demonstrating romantic behavior was significantly more likely in the traditional adventure and the comedy genres than the other genres. Male characters were represented in cartoons significantly more than were female characters, but only in the traditional adventure and the comedy genres. Male characters were more likely than were female characters to use physical aggression, but only in the traditional adventure genre. Behaviors that were relatively more likely among female characters across genres included showing fear, acting romantic, being polite, and acting supportive. Most of the significant differences were also associated with very large effect sizes.     

Non‐generalized and generalized conditioned reinforcers: establishment and validation

Conditioned reinforcers, or tokens, are frequently used in clinical settings; however, little applied research has focused on establishing and validating their effectiveness. Following pairing of a novel token with an edible reinforcer in the present study, preference and reinforcer assessments verified that the tokens functioned as conditioned reinforcers. Results indicated that the tokens were established as conditioned reinforcers that matched the reinforcer value of the primary reinforcers with which they had been paired. The effects of motivating operations (MOs) on the effectiveness of these conditioned reinforcers were then evaluated. Conditioned reinforcer effectiveness decreased during satiation conditions. Subsequently it was found that increasing the number of backup reinforcers with which the token was paired resulted in the effectiveness maintaining during satiation conditions.
