The effects of video feedback on running form

Correct running form is important for injury prevention; as such, correct form promotes continued engagement in running as a long-term form of exercise. Researchers have shown video feedback to be an effective strategy to improve athletic form for a variety of sports, but it has not been evaluated in any behavior analytic research as a method for improving running form. The purpose of this study is to evaluate the effectiveness of video feedback to improve running form for regular runners. During baseline, each participant was video recorded while running without any feedback (verbal or video). During intervention, the researcher recorded the participant, then showed them the video and provided feedback on correct or incorrect form, according to a 9-step task analysis. Results show that all three participants achieved 100% correct steps on the task analysis when video feedback was used to maintain their form during follow-up.     

A new Big Five: fundamental principles for an integrative science of personality

Despite impressive advances in recent years with respect to theory and research, personality psychology has yet to articulate clearly a comprehensive framework for understanding the whole person. In an effort to achieve that aim, the current article draws on the most promising empirical and theoretical trends in personality psychology today to articulate 5 big principles for an integrative science of the whole person. Personality is conceived as (a) an individual's unique variation on the general evolutionary design for human nature, expressed as a developing pattern of (b) dispositional traits, (c) characteristic adaptations, and (d) self-defining life narratives, complexly and differentially situated (e) in culture and social context. The 5 principles suggest a framework for integrating the Big Five model of personality traits with those self-defining features of psychological individuality constructed in response to situated social tasks and the human need to make meaning in culture.     

Predicting eating disorder group membership: an examination and extension of the sociocultural model

The purpose of this research was to examine and extend portions of the sociocultural model of bulimia nervosa (Stice, E. (1994). Review of the evidence for a sociocultural model of bulimia nervosa and an exploration of the mechanisms of action. Clinical Psychology Review, 14, 633-661; Stice, E., & Agras, W. S. (1998). Predicting onset and cessation of bulimic behaviors during adolescence: A longitudinal grouping analysis. Behavior Therapy, 29, 257-276). Participants were women who reported engaging in binge eating at baseline and the 1-year follow-up (n = 26), women who began binge eating between these 2 points (n = 25), and women who did not report binge eating during the course of the study (n = 199). Results of the first discriminant function analysis provided support for the sociocultural model. However, the results of subsequent analyses suggest that additional variables, including stress, escape-avoidance coping, and interoceptive awareness, emerged as important. Implications of these findings for our understanding of the development and maintenance of binge eating are discussed.     

Mental reinstatement of context and return of fear in spider-fearful participants

Extant findings in the animal and human conditioning literature demonstrate that renewal, termed return of fear in studies with humans, occurs when reexposure to a previously feared phobic stimulus occurs in a context different than the one present during extinction. The present study investigated whether mental reinstatement of the treatment context at follow-up could attenuate context-based return of fear. Forty-eight spider-fearful individuals received exposure therapy in one of two contexts, and were followed-up 1 week later in the treatment or a new context. Half of the participants received instructions to mentally reinstate the treatment context before the follow-up test. Self-report data replicated previous research on contextually driven return of fear. Furthermore, participants who mentally reinstated the treatment context, before encountering the phobic stimulus in a new context at follow-up, had less return of fear than those who did not. Limitations of the current study, as well as implications for phobia treatment, are discussed.     

Preschool children master the logic of number word meanings

Although children take over a year to learn the meanings of the first three number words, they eventually master the logic of counting and the meanings of all the words in their count list. Here, we ask whether children's knowledge applies to number words beyond those they have mastered: Does a child who can only count to 20 infer that number words above 'twenty' refer to exact cardinal values? Three experiments provide evidence for this understanding in preschool children. Before beginning formal education or gaining counting skill, children possess a productive symbolic system for representing number.     

Non-symbolic arithmetic in adults and young children

Five experiments investigated whether adults and preschool children can perform simple arithmetic calculations on non-symbolic numerosities. Previous research has demonstrated that human adults, human infants, and non-human animals can process numerical quantities through approximate representations of their magnitudes. Here we consider whether these non-symbolic numerical representations might serve as a building block of uniquely human, learned mathematics. Both adults and children with no training in arithmetic successfully performed approximate arithmetic on large sets of elements. Success at these tasks did not depend on non-numerical continuous quantities, modality-specific quantity information, the adoption of alternative non-arithmetic strategies, or learned symbolic arithmetic knowledge. Abstract numerical quantity representations therefore are computationally functional and may provide a foundation for formal mathematics.     

Is extracurricular participation associated with beneficial outcomes? Concurrent and longitudinal relations

The authors examined the relations between participation in a range of high school extracurricular contexts and developmental outcomes in adolescence and young adulthood among an economically diverse sample of African American and European American youths. In general, when some prior self-selection factors were controlled, 11th graders' participation in school clubs and organized sports was associated with concurrent indicators of academic and psychological adjustment and with drug and alcohol use. In addition, participation in 11th grade school clubs and prosocial activities was associated with educational status and civic engagement at 1 year after high school. A few of the concurrent and longitudinal relations between activity participation and development were moderated by race and gender. Finally, breadth of participation, or number of activity contexts, was associated with positive academic, psychological, and behavioral outcomes.     

The pursuit of self-esteem: contingencies of self-worth and self-regulation

Successful self-regulation is defined as the willingness to exert effort toward one's most important goals, while taking setbacks and failures as opportunities to learn, identify weaknesses and address them, and develop new strategies toward achieving those goals. Contingencies of self-worth can facilitate self-regulation because people are highly motivated to succeed and avoid failure in domains of contingency. However, because boosts in self-esteem are pleasurable and drops in self-esteem are painful, protection, maintenance, and enhancement of self-esteem can become the overriding goal. Several pitfalls for self-regulation can result, especially when tasks are difficult and failure is likely. In this article, we describe a program of research examining these self-regulation pitfalls associated with contingent self-worth and suggest that learning orientations, particularly the willingness to embrace failure for the learning it affords, foster successful self-regulation even in people with highly contingent self-esteem.     

Effects of writing about emotions versus goals on psychological and physical health among third-year medical students

A randomized, controlled trial compared writing about emotional topics (EMO) to writing about goals as the "best possible self" (BPS; after King, 2001) and evaluated emotional approach coping, i.e., efforts to cope through processing and expressing emotion, as a moderator of writing effects on psychological and physical health in 64 third-year medical students. In participants with higher baseline hostility, the EMO condition was associated with less hostility at 3 months compared to the BPS and control conditions. Emotional processing (EP) and emotional expression (EE) moderated the effect of experimental condition on depressive symptoms at 3 months; high EP/EE participants reported fewer depressive symptoms in the EMO condition, whereas low EP/EE individuals reported fewer depressive symptoms in the BPS condition compared to the EMO and control conditions. A moderating effect of EP on physical health was also identified, such that low EP individuals who wrote about goals (BPS) had fewer health care visits at 3 months compared to low EP participants in the EMO and control conditions.     

Positive affect and the experience of meaning in life

Six studies examined the role of positive affect (PA) in the experience of meaning in life (MIL). Study 1 showed strong relations between measures of mood, goal appraisals, and MIL. In multivariate analyses, PA was a stronger predictor of MIL than goal appraisals. In Study 2, the most consistent predictor of the experience of meaning in a day was the PA experienced that day. Later, global MIL was predicted by average daily PA, rather than average daily MIL. Study 3 demonstrated no prospective relations between measures of MIL and PA over 2 years. In Study 4, priming positive mood concepts enhanced MIL. In Study 5, manipulated positive mood enhanced ratings of MIL for those who were not given an attributional cue for their moods. In Study 6, PA was associated with a high level of distinction between meaningful and meaningless activities. Results indicate that positive moods may predispose individuals to feel that life is meaningful. In addition, positive moods may increase sensitivity to the meaning-relevance of a situation.
