Executive functioning and psychological adjustment in children and youth with spina bifida

Children and adolescents with spina bifida are at risk for poor neuropsychological functioning and psychological outcomes. The relationship between executive functioning and psychological adjustment is an area worthy of investigation in this population. The current study assessed executive functioning and psychological outcomes in a group of children and adolescents with spina bifida (SBM) (n = 51) and nondisabled controls (n = 45). A mediation model was hypothesized, such that Metacognition, as measured by the Behavior Rating Inventory of Executive Function (BRIEF), mediated the relationship between group status (spina bifida versus nondisabled controls) and psychological outcomes. Results indicated that metacognitive skills fully explained the relationship between group and internalizing and depressive symptoms as reported by mothers. In particular, specific components of the BRIEF Metacognition composite were most responsible for this relationship, including Initiate, Working Memory, and Plan/Organize. The study limitations include its cross-sectional nature that precludes drawing conclusions about causality. The results have implications for treatment interventions for children and adolescents with spina bifida and typically developing individuals.     

The cost of callousness: regulating compassion influences the moral self-concept

It has often been argued that compassion is fundamental to morality. Yet people often suppress compassion for self-interested reasons. We provide evidence that suppressing compassion is not cost free, as it creates dissonance between a person's moral identity and his or her moral principles. We instructed separate groups of participants to regulate their compassion, regulate their feelings of distress, or freely experience emotions toward compassion--inducing images. Participants then reported how central morality was to their identities and how much they believed that moral rules should always be followed. Participants who regulated compassion-but not those who regulated distress or experienced emotions--showed a dissonance-based trade-off. If they reported higher levels of moral identity, they had a greater belief that moral rules could be broken. If they maintained their belief that moral rules should always be followed, they sacrificed their moral identity. Regulating compassion thus has a cost of its own: It forces trade-offs within a person's moral self-concept.     

Neuropsychological Sequelae of PTSD and TBI Following War Deployment among OEF/OIF Veterans

Posttraumatic stress disorder (PTSD) and mild traumatic brain injury (mTBI) are highly prevalent among Veterans of the conflicts in Iraq and Afghanistan. These conditions are associated with common and unique neuropsychological and neuroanatomical changes. This review synthesizes neuropsychological and neuroimaging studies for both of these disorders and studies examining their co-occurrence. Recommendations for future research, including use of combined neuropsychological and advanced neuroimaging techniques to study these disorders alone and in concert, are presented. It is clear from the dearth of literature that addiitonal studies are required to examine and understand the impact of specific factors on neurocognitive outcome. Of particular relevance are temporal relationships between PTSD and mTBI, risk and resilience factors associated with both disorders and their co-occurrence, and mTBI-specific factors such as time since injury and severity of injury, utilizing comprehensive, yet targeted cognitive tasks.     

Comma N' cents in pricing: The effects of auditory representation encoding on price magnitude perceptions

Numbers and prices can be processed and encoded in three different forms: 1) visual [based on their written form in Arabic numerals (e.g., 72)], 2) verbal [based on spoken word-sounds (e.g., “seventy” and “two”), and 3) analog (based on judgments of relative “size” or amount (e.g., more than 70 but less than 80)]. In this paper, we demonstrate that including commas (e.g., $1599 vs. $1599) and cents (e.g., $1599.85 vs. $1599) in a price's Arabic written form (i.e., how it is perceived visually) can change how the price is encoded and represented verbally in a consumer's memory. In turn, the verbal encoding of a written price can influence assessments of the numerical magnitude of the price. These effects occur because consumers non-consciously perceive that there is a positive relationship between syllabic length and numerical magnitude. Three experiments are presented demonstrating this important effect.     

Emerging narrative discourse skills 18 months after traumatic brain injury in early childhood

This study examined the longer term effect of traumatic brain injury (TBI), approximately 18 months post-injury, on emerging narrative discourse skills of 85 children with orthopaedic injury (OI), 43 children with moderate TBI, and 19 children with severe TBI who were between 3 years and 6 years 11 months at injury. Children with TBI performed worse than children with OI on most discourse indices. Children with severe TBI were less proficient than children with moderate TBI at identifying unimportant story information. Age and pragmatic skills were predictors of discourse performance.     

How psychological momentum changes in athletes during a sport competition

ObjectivesThe present research sought to examine changes in psychological momentum (PM) during sport competitions through the lens of a dynamical systems approach.DesignMale regional-level cyclists competed in cycling duels on home trainers.MethodImages of moving avatars of the cyclists were projected on a wall, and were manipulated so that one cyclist was exposed to an ascending performance scenario (i.e., positive momentum) and the other to a descending performance scenario (i.e., negative momentum). Every 3 min, the cyclists answered PM items by using a keyboard that was placed on the handlebars of their bicycles. Additionally, exerted power was continuously recorded.ResultsResults revealed an asymmetrical critical boundary pattern for PM perceptions indicating that negative PM was triggered more easily than positive PM. Exerted power was generally higher during the negative momentum scenario than during the positive momentum scenario. In addition, exerted power slowly decreased over both momentum scenarios, and this decrease was faster at the very beginning of the negative momentum scenario.ConclusionResults indicate that PM perceptions possess the dynamical properties of nonlinearity and history-dependence. Moreover, the finding that exerted power was higher in the negative momentum scenario was interpreted as a resistance behavior that occurs while experiencing negative momentum. The anticipated decreases in both exerted power and PM perceptions in the negative momentum scenario converge to support the notion that negative PM is a stronger attractor than positive PM. The present study confirms that PM is a dynamical phenomenon and offers fruitful avenues for future research.     

Expressed Emotion,Appraisal and Coping by Patients with Recent-onset Schizophrenia: A Pilot Investigation

This pilot study sought to follow up on indications that patients from households with high levels of expressed emotion (EE) differ from those from households with low levels of EE in ways not assessed in typical symptom rating profiles. We examined how patients appraised and coped with a prominent societal stressor. Soon after the start of the Gulf War, 22 patients with recent-onset schizophrenia living in Los Angeles appraised the stressor and completed a coping questionnaire. Results indicated that patients from high-EE homes were likely to use emotion-based confrontational methods to cope with the crisis, while patients from low-EE environments were likely to use avoidance and denial. Patients from high-EE homes thus coped with this non-familial, societal stressor in a way similar to the way in which they have been observed to cope with family conflict: they more readily expressed their anger and frustration than patients from low-EE homes. These pilot data suggest that increased attention should be directed toward those patient behaviours that may be associated with either an increase or decrease in negative affective behaviour from relatives. It may also be fruitful to consider more broadly the adaptive and maladaptive features of the preferred coping strategies of patients from high-EE and low-EE environments.     

On Berliner's Thinking in Jazz: The Infinite Are of Improvisation

In order to characterize divergent thinking, the author performed self-organization feature mapping on the multidimensional data of Williams's (1980) Creative Thinking Tests. The resultant population map of cluster was obtained. Principal-components analysis was also applied to determine the most significant features characterizing divergent thinking. Using the two most significant features to define a 2-dimensional space, the author ascertained characterizations of each cluster over the population map. The results obtained compared favorably with the topological structure of the population map. A secondary differentiation was found in the divergent thinking test. The topological structure for divergent thinking should prove useful for characterization of creative thinking.     

Combat exposure,psychological symptoms,and marital satisfaction in National Guard soldiers who served in Operation Iraqi Freedom from 2005 to 2006

Abstract

In current military operations in Iraq and Afghanistan, US National Guard (NG) troops are serving longer deployments than ever before. Little is known, however, about how such deployments affect this population of individuals, relative to active component (AC) troops. This study investigated the extent of combat exposure, severity of post-deployment psychological symptoms, and general interpersonal functioning, as well as the interrelationships of these variables, in 50 NG soldiers who served a 12-month deployment in Iraq from 2005 to 2006. The results indicate that combat exposure and post-deployment post-traumatic stress symptoms in this sample are greater than those in NG veterans of past military operations, and similar to those of full-time soldiers in current operations. Furthermore, the patterns of interrelationships between combat exposure, psychological symptoms, and interpersonal variables were similar to those detected in prior research on AC troops. These results suggest that NG veterans of current military operations may require similar services as active duty veterans. Given that NG troops are less integrated into the military structure, specific outreach efforts may be needed to help NG veterans to receive such services.     

Cross-sectional and longitudinal confirmatory factor models for the german test anxiety inventory: A construct validation

Construct validity of the German Test Anxiety Inventory (TAI-G) was tested in two respects. Firstly, the purported four-dimensional structure of the TAI-G (comprising subscales Emotionality, Worry, Interference, and Lack of Confidence) as well as relations of the test anxiety dimensions to self-efficacy were tested. Secondly, the trait conception of the TAI-G was tested within the framework of Latent State-Trait theory. The TAI-G was given to a student sample (N=302) on three occasions with a time interval of 2 weeks along with a study-specific self-efficacy scale on occasion 1. Dimensionality assumptions as well as relations with self-efficacy were tested using cross-sectional second-order confirmatory factor analysis. The trait conception was tested separately for TAI-G subscales by specifying longitudinal confirmatory factor models (Latent State-Trait models) and by calculating variance proportions of manifest variables (Latent State-Trait coefficients) referring to different sources of systematic variance (person, situation, and method) based on parameter estimates of the models. Results were supportive of both the purported four-dimensional structure and hypothesized relationships to self-efficacy (i.e., acceptable model fit) as well as of the trait conception of test anxiety (i.e., acceptable model fit and high proportion of variance due to person component). Implications for further validation studies were discussed.
