Getting Luck Properly Under Control

This article proposes a new account of luck and how luck impacts attributions of credit for agents' actions. It proposes an analogy with the expected value of a series of wagers and argues that luck is the difference between actual outcomes and expected value. The upshot of the argument is that when considering the interplay of intention, chance, outcomes, skill, and actions, we ought to be more parsimonious in our attributions of credit when exercising a skill and obtaining successful outcomes, and more generous in our attributions of credit when exercising a skill but obtaining unsuccessful outcomes. Furthermore, the article argues that when agents skillfully perform an action, they deserve the same amount of credit whether their action is successful or unsuccessful in achieving the goal.     

What makes labour and birth traumatic? A survey of intrapartum ‘hotspots’

Evidence suggests between 1% and 6% of women develop post-traumatic stress disorder (PTSD) after childbirth. ‘Hotspots’ are moments of extreme distress during traumatising events that are implicated in symptoms of PTSD. This cross-sectional internet survey of hotspots examined (1) the content of intrapartum hotspots and (2) whether particular events, cognitions or emotions during hotspots are related to PTSD. Women (N?=?675) who experienced a difficult or traumatic birth completed a questionnaire composed of a validated measure of PTSD, questions concerning the existence of hotspots, and a newly developed measure of emotions and cognitions during hotspots. The majority of women (67.4%) reported at least one hotspot during birth and 52.9% had re-experiencing symptoms of these hotspots. Women were more likely to have PTSD if hotspots involved fear and lack of control (odds ratio (OR) 1.30, 95% CI 1.17–1.43) or intrapartum dissociation (OR 1.12, 95% CI 1.05–1.19). Risk of PTSD was higher if hotspots concerned interpersonal difficulties (OR 4.34, 95% CI 2.15–8.77) or obstetric complications (OR 3.35, 95% CI 1.64–6.87) compared to complications with the baby.     

Processing emotional stimuli: Comparison of saccadic and manual choice-reaction times

We compared the speed of discrimination for emotional and neutral faces in four experiments, using a forced-choice saccadic and manual reaction time task. Unmasked, brief (20 ms) bilateral presentation of schematic (Exp. 1) or naturalistic (Exp. 2) emotional/neutral face pairs, led to shorter discrimination of emotional stimuli in saccadic localisation task. When the effect of interference from emotional stimuli is ruled out by showing a pairing of the emotional or neutral face with an outline face, faster saccadic discrimination was obtained for fearful facial expression only (Exp. 3). The manual discrimination reaction time was not significantly different for emotional versus neutral stimuli. To explore the absence of a manual RT effect we manipulated the stimulus duration (20 ms vs. 500 ms: Exp. 4). Faster saccadic discrimination of emotional stimuli was observed at both durations. For manual responses, emotional bias was observed only at the longest duration (500 ms). Overall, comparison of saccadic and manual responses shows that faster discrimination of emotional/neutral stimuli can be carried out within the oculomotor system. In addition, emotional stimuli are processed preferentially to neutral face stimuli.     

Removing the own-race bias in face recognition by attentional shift using fixation crosses to diagnostic features: An eye-tracking study

Hills and Lewis (2011) have demonstrated that the own-race bias in face recognition can be reduced or even removed by guiding participants' attention and potentially eye movements to the most diagnostic visual features. Using the same old/new recognition paradigm as Hills and Lewis, we recorded Black and White participants' eye movements whilst viewing Black and White faces following fixation crosses that preceded the bridge of the nose (between the eyes) or the tip of the nose. White faces were more accurately recognized when following high fixation crosses (that preceded the bridge of the nose) than when following low fixation crosses. The converse was true for Black faces. These effects were independent of participant race. The fixation crosses attracted the first fixation but had less effect on other eye-tracking measures. Furthermore, the location of the first fixation was predictive of recognition accuracy. These results are consistent with an attentional allocation model of the own-race bias in face recognition and highlight the importance of the first fixation for face perception (cf. Hsiao & Cottrell, 2008).     

Cognitive Behavioral Therapy for Bariatric Surgery Patients: Preliminary Evidence for Feasibility,Acceptability, and Effectiveness

Bariatric surgery is the most effective treatment for extreme obesity; however, 20% to 50% of patients begin to regain their weight within the first 1.5 to 2 years following surgery. Despite some psychosocial factors predicting postoperative weight loss and weight regain, psychosocial interventions are not routinely offered in bariatric surgery programs. In this paper, we describe a 6-session cognitive behavioral therapy (CBT) intervention for preoperative and postoperative bariatric surgery patients with maladaptive eating behaviors or thought patterns, which can be delivered either in person or by telephone. In addition, we describe a small pilot study (n = 8) designed to examine the feasibility and acceptability of the CBT intervention, as well as its effectiveness in improving eating pathology and psychosocial functioning. Most pilot study participants reported improvements in binge eating severity, emotional eating, and depression from pre- to posttreatment, and all participants provided positive qualitative feedback regarding the intervention.     

Social problem-solving among adolescents treated for depression

Studies suggest that deficits in social problem-solving may be associated with increased risk of depression and suicidality in children and adolescents. It is unclear, however, which specific dimensions of social problem-solving are related to depression and suicidality among youth. Moreover, rational problem-solving strategies and problem-solving motivation may moderate or predict change in depression and suicidality among children and adolescents receiving treatment. The effect of social problem-solving on acute treatment outcomes were explored in a randomized controlled trial of 439 clinically depressed adolescents enrolled in the Treatment for Adolescents with Depression Study (TADS). Measures included the Children's Depression Rating Scale-Revised (CDRS-R), the Suicidal Ideation Questionnaire - Grades 7-9 (SIQ-Jr), and the Social Problem-Solving Inventory-Revised (SPSI-R). A random coefficients regression model was conducted to examine main and interaction effects of treatment and SPSI-R subscale scores on outcomes during the 12-week acute treatment stage. Negative problem orientation, positive problem orientation, and avoidant problem-solving style were non-specific predictors of depression severity. In terms of suicidality, avoidant problem-solving style and impulsiveness/carelessness style were predictors, whereas negative problem orientation and positive problem orientation were moderators of treatment outcome. Implications of these findings, limitations, and directions for future research are discussed.     

Extreme thinking in clinically depressed adolescents: Results from the Treatment for Adolescents with Depression Study (TADS)

The purpose of this report is to examine relations between extreme thinking, as measured by the Dysfunctional Attitudes Scale, and the maintenance of gains among adolescents who participated in the Treatment for Adolescents with Depression Study (TADS). We examine extreme thinking among 327 adolescents (mean age = 14.56, 57% female, 75% White) who received cognitive behavior therapy (CBT), fluoxetine (FLX), or a combination of CBT and FLX (COMB). Among those who met remission status on the Children’s Depression Rating Scale - Revised (CDRS-R ≤ 28; 56 at week 12, 79 at week 18) extreme thinking did not predict failure to maintain remission. This is in contrast to findings with depressed adults. Treatment influenced level of extreme thinking, and this appeared to be driven by greater endorsement of positively valenced beliefs as opposed to a decrease in negatively valenced beliefs. Developmental or investigation characteristics may account for the discrepancy in findings.     

Fiction, Fashion, and Function Revisited: An Introduction to the Special Issue on Gendered Body Image, Part II

Continuing the theme of our special issue (Calogero and Tylka, Sex Roles, 63, 1-5. 2010), we present a collection of novel studies that detail how gendered experiences of the body constrain and impact body image. Specifically, Part II of the special issue explores gendered body image from vantage points of intersectionality and diversity—importantly recognizing that culturally-prescribed appearance ideals for women and men combine with multiple individual variables and identities (e.g., gender role identification, developmental stage, culture and cultural identification, family environment, sexual orientation, and personality) to mold body image. Each study advances our understanding of how individual difference and identity variables, such as the above, shape the experience of gendered body messages in western societies. To facilitate the presentation of the studies, we organized this research into three streams. The first stream explores how gendered messages are inscribed onto the body in childhood and speaks to the stability of gendered body image throughout adolescence and adulthood. The second stream investigates macro- (culture) and micro- (family environment) level body and appearance ideals that tend to shape body-related self-perceptions. The third stream illustrates the complex connection between gendered body ideals, the adoption of these ideals as a personal standard, and behaviors geared toward altering the body to become more consistent with these ideals. Part II concludes with a discussion of how these papers may be used to promote positive body image for girls/women and boys/men.
