Processes and outcomes in prevention-focused time-limited groups for girls

Processes and outcomes in 8-week prevention-focused, school-based groups for preadolescent girls were assessed in a naturalistic study. Specifically, whether such groups would facilitate their social-emotional development and whether affiliative processes in the groups were related to outcome were explored. In addition to expecting the groups to be effective, it was hypothesized that affiliative processes would be directly related to outcome and, more particularly, that increased positive affiliative feelings from the group toward the individual would be more predictive of positive treatment outcome than increased positive feelings from the individual toward the group. While findings did not support these hypotheses linking process to outcome, ancillary analyses revealed that different patterns of affiliation over time (i.e., U-shape pattern versus inverted U-shape pattern) distinguished the high- versus low-outcome participants, respectively.     

Age differences in contingency judgement linked to perceptual segregation

We demonstrate large differences in judging positive and null contingencies between younger and older adults with a task commonly used to explore cue competition in both contingency and causality judgements. The one-phase blocking task uses two cues, with separate contingencies with the same outcome. The age differences persisted even when participants knew in advance which of the two contingencies to judge. The age differences disappeared, however, when the stimulus display contained markers aiding perceptual segregation. We suggest that the age differences elicited in the one-phase blocking task are linked to decrements in perceptual segregation.     

Increased spatial salience in the social Simon task: A response-coding account of spatial compatibility effects

A spatial compatibility effect (SCE) is typically observed in forced two-choice tasks in which a spatially defined response (e.g., pressing a left vs. a right key) has to be executed to a nonspatial feature of a stimulus (e.g., discriminating red from green) that is additionally connoted by a spatial feature (e.g., the stimulus points to the left or the right). Responses are faster and more accurate when the response side and the spatial stimulus feature are compatible than when they are incompatible. Previous research has demonstrated that SCEs are diminished when stimuli from only one response category are responded to in individual go/no-go tasks, whereas SCEs reemerge when two participants work jointly on two complementary, individual go/no-go tasks in a joint go/no-go task setting. This social Simon effect has been considered evidence for shared task representations. We show that SCEs emerge in individual go/no-go tasks when the spatial dimension is made more salient, whereas SCEs are eliminated in joint go/no-go tasks when the spatial dimension is made less salient. These findings are consistent with an account of social Simon effects in terms of spatial response coding, whereas they are inconsistent with an account of shared task representations. The relevance of social factors for spatial response coding is discussed.     

Sorting the Liars from the Truth Tellers: The Benefits of Asking Unanticipated Questions on Lie Detection

We examined the effect of asking unanticipated interview questions on lie detection. We set up a room in which truth tellers (N = 40) performed five tasks. Liars (N = 40) observed the activity room through a window and were asked to generate a story in which they claim to have performed five tasks. The interview schedule included four thematically related pairs of questions. The first question of each pairing was easy for interviewees to anticipate, as it reflected how events are typically recalled. However, the second included a perspective shift (temporal or spatial), which made the question harder to anticipate. We also measured cognitive load via performance on an object sorting secondary task that interviewees undertook during interview. Compared with truth tellers, liars' verbal responses showed a greater decline in details across three out of four question pairs. Liars also sorted significantly fewer objects per minute on the secondary task. Copyright © 2012 John Wiley & Sons, Ltd.     

Stress and Well-Being Among Parents of Children with Potocki-Lupski Syndrome

Potocki-Lupski syndrome (PTLS) or duplication 17p11.2 syndrome is a newly characterized condition causing a variety of health problems with variable severity, including failure to thrive in infancy and childhood, hypotonia, structural heart anomalies, cognitive impairments, speech and learning difficulties, and autism. Due to its recent clinical characterization little is known about the psychosocial impact of this condition on patients and their families. This study evaluated whether parental psychosocial outcomes were associated with children’s PTLS disease severity. Parents of 58 children with PTLS completed a cross-sectional survey that assessed parental stress, quality of life, and coping skills. Parental functioning was associated with greater severity of feeding difficulty and with lower severity of a cardiovascular defect. Findings from this study highlight potential support needs of parents of children affected by PTLS and suggest ways in which these needs may be addressed.     

Hoping to Live a “Normal” Life Whilst Living with Unpredictable Health and Fear of Death: Impact of Cystic Fibrosis on Young Adults

This study aimed to explore the hopes and fears of young adults with cystic fibrosis (CF). Fifteen young adults with CF, aged 18–29, were interviewed about their hopes and fears using a grounded theory approach. Five themes were identified during the analysis: perceptions of living with unpredictable health and fear of death and dying; hopes for normality; hopes for a normal relationship and/or marriage; hopes for having children; and hopes for a normal work life. Participants feared the unpredictable nature of CF and the suffering that they believed they would have to endure due to ill health before premature death. Despite their fears, participants hoped to live a “normal” life by achieving their hopes of having long-lasting relationships, having children and pursuing a career. The findings highlight the need to help alleviate the fears of young adults with CF and to enable them to plan to achieve their hopes, hence giving them a sense of control over their condition.     

Analytical Problems and Suggestions in the Analysis of Behavioral Economic Demand Curves

Behavioral economic demand curves (Hursh, Raslear, Shurtleff, Bauman, & Simmons, 1988) are innovative approaches to characterize the relationships between consumption of a substance and its price. In this article, we investigate common analytical issues in the use of behavioral economic demand curves, which can cause inconsistent interpretations of demand curves, and then we provide methodological suggestions to address those analytical issues.

We first demonstrate that log transformation with different added values for handling zeros changes model parameter estimates dramatically. Second, demand curves are often analyzed using an overparameterized model that results in an inefficient use of the available data and a lack of assessment of the variability among individuals.

To address these issues, we apply a nonlinear mixed effects model based on multivariate error structures that has not been used previously to analyze behavioral economic demand curves in the literature. We also propose analytical formulas for the relevant standard errors of derived values such as P _max, O _max, and elasticity. The proposed model stabilizes the derived values regardless of using different added increments and provides substantially smaller standard errors. We illustrate the data analysis procedure using data from a relative reinforcement efficacy study of simulated marijuana purchasing.     

Emotional self‐efficacy,graduate employability,and career satisfaction: Testing the associations

Graduate employability has been the subject of little empirical research. There are a number of difficulties in defining and measuring graduate employability, which means that there is a paucity of research that looks at its predictors and outcomes. Previous work has proposed that emotional competence improves graduate employability, and this study further investigates this idea by examining the association between emotional self‐efficacy and employability. Also investigated is the association between employability and career satisfaction. Working graduates (N = 306) completed measures of emotional self‐efficacy, self‐perceived employability, and career satisfaction, and the data were analysed using structural equation modelling. We found emotional self‐efficacy to be an important predictor of graduate employability. Additionally, we found that graduate employability mediates the relationship between emotional self‐efficacy and career satisfaction. Some recommendations, in light of these findings, are discussed.     

Pointing and the interference effect in obsessive‐compulsive disorder (OCD)

The interference effect in obsessive‐compulsive disorder (OCD) was investigated in order to analyze cognitive aspects of motor stereotypy in OCD‐related compulsions. So far, the domain of cognitive control in compulsive behavior has been under‐investigated. Twelve participants (OCD patients and healthy controls) completed a newly created computer‐based pointing task as well as standard clinical and psychological background measures. Findings showed that the patients displayed a larger visual interference effect compared to the controls and pointing paths were longer in time as well as distance when a distractor stimulus was present. It is concluded that, for compensation, patients would need to generate excessive amounts of attentional resources not available to overcome motor rigidity on the one side and visual distraction on the other side.
