Why so confident? The influence of outcome desirability on selective exposure and likelihood judgment

Previous studies that have directly manipulated outcome desirability have often found little effect on likelihood judgments (i.e., no desirability bias or wishful thinking). The present studies tested whether selections of new information about outcomes would be impacted by outcome desirability, thereby biasing likelihood judgments. In Study 1, participants made predictions about novel outcomes and then selected additional information to read from a buffet. They favored information supporting their prediction, and this fueled an increase in confidence. Studies 2 and 3 directly manipulated outcome desirability through monetary means. If a target outcome (randomly preselected) was made especially desirable, then participants tended to select information that supported the outcome. If made undesirable, less supporting information was selected. Selection bias was again linked to subsequent likelihood judgments. These results constitute novel evidence for the role of selective exposure in cases of overconfidence and desirability bias in likelihood judgments.     

Maternal Psychopathology and Early Child Temperament Predict Young Children’s Salivary Cortisol 3 Years Later

Neuroendocrine dysfunction is hypothesized to be an early emerging vulnerability marker for depression. We tested whether the main and interactive effects of maternal psychopathology and early child temperamental vulnerability for depression assessed at age three predicted offspring’s basal cortisol function at age 6 years. 228 (122 males) children participated in the baseline and follow-up assessments. At age three, maternal lifetime psychopathology was assessed with a diagnostic clinical interview, and child temperamental positive affectivity (PA) and negative affectivity (NA) were assessed using laboratory observations. At age six, children’s waking and evening cortisol were assessed on 2 days. Maternal lifetime anxiety predicted offspring’s higher morning cortisol at age six. Child temperamental NA at age three predicted higher evening cortisol at age six. There was a significant interaction between maternal lifetime depression and child temperamental PA at age three in predicting offspring’s morning cortisol at age six. For the offspring of mothers with lifetime depression, higher PA at age 3 predicted lower morning cortisol at age 6. These findings highlight the importance of examining the main and interactive effects of maternal psychopathology and early child temperamental vulnerability in predicting the development of offspring’s stress physiology. Findings hold significance in identifying etiological mechanisms of risk and delineating the complex developmental pathways to psychopathology.     

Trauma Exposure in Anxious Primary Care Patients

The present study examined rates of trauma exposure, clinical characteristics associated with trauma exposure, and the effect of trauma exposure on treatment outcome in a large sample of primary care patients without posttraumatic stress disorder (PTSD). Individuals without PTSD (N?=?1,263) treated as part of the CALM program (Roy-Byrne et al., Journal of the American Medical Association 303(19)1921–1928, 2010) were assessed for presence of trauma exposure. Those with and without trauma exposure were compared on baseline demographic and diagnostic information, symptom severity, and responder status six months after beginning treatment. Trauma-exposed individuals (N?=?662, 53 %) were more likely to meet diagnostic criteria for Obsessive Compulsive Disorder and had higher levels of somatic symptoms at baseline. Individuals with and without trauma exposure did not differ significantly on severity of anxiety, depression, or mental health functioning at baseline. Trauma exposure did not significantly impact treatment response. Findings suggest that adverse effects of trauma exposure in those without PTSD may include OCD and somatic anxiety symptoms. Treatment did not appear to be adversely impacted by trauma exposure. Thus, although trauma exposure is prevalent in primary care samples, results suggest that treatment of the presenting anxiety disorder is effective irrespective of trauma history.     

Confirmatory and Exploratory Factor Analyses of Parental Authority Questionnaire in Urban India

The present study examined the factor structure of a widely used measure of parenting style in three samples from Northwestern India. College Students (n = 195) completed Parental Authority Questionnaire (PAQ; Buri in J Pers Assess 57:110–119, 1991), and mothers of children attending high-school (n = 275), and middle-school (n = 145) completed its parent-report version Parental Authority Questionnaire-Revised (PAQ-R; Reitman et al. in J Psychopathol Behav Assess 24:119–127, 2002). Preliminary findings revealed that across three samples Cronbach’s alpha values ranged from poor to acceptable, with permissive parenting subscale of the PAQ/PAQ-R having the lowest value, whereas the authoritarian parenting had the highest value. Confirmatory factor analysis revealed that none of the models achieved satisfactory fit (i.e., CFI > .90). Exploratory factor analysis revealed that a two factor structure (with first component consisting of authoritative and permissive items, and the second component consisting of authoritarian items) rendered Cronbach’s alpha in the acceptable range. Only PAQ/PAQ-R authoritarian scale was correlated with youth adjustment problems across all three samples, while findings concerning authoritative and permissive scales were mixed. The findings suggest that only PAQ/PAQ-R authoritarian scale is reliable and valid in urban, middle-class, educated families in India, and encourage researchers to develop culturally relevant measures of parenting for this population.     

Stroop Interference,Practice, and Aging

We report two experiments that investigate practice effects on Stroop color-word interference in older and younger adults. Both experiments employed a computerized, single-item version of the Stroop task with a voice response, and both involved practice over hundreds of trials. Both experiments showed generally similar practice patterns, including a practice-related reduction in the size of the color-word interference effect. However, the older group continued to show a larger interference effect throughout practice. These findings indicate that older adults show the same trend in practice-related improvement on the Stroop task as younger adults.     

Body size dissatisfaction and avoidance behavior: How gender,age, ethnicity,and relative clothing size predict what some won’t try

Sixty-eight percent of U.S. adults are overweight/obese, and this epidemic has physical, psychosocial, and behavioral consequences. An internet sample of adults (N = 2997) perceiving themselves as larger than ideal in clothing size reported their body mass index (BMI), relative clothing size (RS; discrepancy between current and ideal size), and avoidance behaviors. Exploratory factor analysis of 10 avoidance items produced social avoidance and body display avoidance factors. A relative importance analysis revealed RS as a better predictor than BMI for avoidance. A hierarchical multivariate analysis of covariance found RS to predict both avoidance constructs. The relationship between RS and both avoidance constructs was stronger for women than men, and for younger as compared to older participants. Caucasians reported more body display avoidance than African Americans. This suggests that personal dissatisfaction with body size may deter involvement in varied life events and that women are especially avoidant of activities that entail displaying their bodies.     

Frequency judgements: the problem of defining a perceptual event

In four experiments the conditions under which frequency judgments reflect the relative frequency of complex perceptual events were explored. Subjects viewed a series of 4 x 4 grids each containing seven items, which were letters and numbers in one of four typefaces. Later judgments of the relative frequency with which particular letters appeared in particular typefaces were unaffected by a warning about an upcoming frequency judgment task, but were affected by both the time available for processing the stimuli and the nature of the cover task subjects engaged in while viewing the grids. Frequency judgments were poor when exposure durations were less than 2 s and when the cover task directed subjects' attention merely to the locations of the items within the grids. Frequency judgments improved when the cover task directed subjects' attention to the identity of the stimuli, especially to the conjunction of letter and typeface. The results suggest that frequency estimation of complex stimuli may be possible only for stimuli that have been processed as phenomenal objects.
