School Readiness in Preschool-Age Children with Critical Congenital Heart Disease.

This study examined the nature, variability, and predictors of school readiness difficulties in young children with critical congenital heart disease (CCHD). We hypothesized that, compared to a community control (CC) group, children with CCHD would score less well on measures of readiness and that readiness would be associated with CCHD-related risk factors. Children (60 CCHD and 60 CC) were 4 to 5 years of age and not yet attending kindergarten. Readiness measures included tests of cognition, executive function, motor ability, and pre-academic skills. Caregivers provided child behavior ratings. Analyses examined group differences in readiness, readiness profiles, and associations of readiness with CCHD-related medical risk factors. The CCHD group had lower scores than the CC group on testing and higher caregiver ratings of problems in social communication, as well as higher rates of deficits on several of the measures. Latent class analysis provided evidence for different readiness profiles, with more children with CCHD displaying profiles characterized by weaknesses in readiness. CCHD-related medical risk factors associated with readiness problems in the CCHD group included a co-morbid genetic disorder, postnatal diagnosis of CCHD, major perioperative complication, and longer periods of hospitalizations, cardiopulmonary bypass, and aortic cross-clamp placements. Findings document multiple problems in school readiness in young children with CCHD. Deficits vary across individuals and are associated with higher medical risk. Results confirm the importance of screening for school readiness in these children and suggest areas to target in designing screening measures and providing early childhood interventions.

Choke or thrive? The relation between salivary cortisol and math performance depends on individual differences in working memory and math-anxiety.

In the current study, we explored how a person's physiological arousal relates to their performance in a challenging math situation as a function of individual differences in working memory (WM) capacity and math-anxiety. Participants completed demanding math problems before and after which salivary cortisol, an index of arousal, was measured. The performance of lower WM individuals did not depend on cortisol concentration or math-anxiety. For higher WM individuals high in math-anxiety, the higher their concentration of salivary cortisol following the math task, the worse their performance. In contrast, for higher WM individuals lower in math-anxiety, the higher their salivary cortisol concentrations, the better their performance. For individuals who have the capacity to perform at a high-level (higher WMs), whether physiological arousal will lead an individual to choke or thrive depends on math-anxiety.

The neural substrates of action identification.

Mentalization is the process by which an observer views a target as possessing higher cognitive faculties such as goals, intentions and desires. Mentalization can be assessed using action identification paradigms, in which observers choose mentalistic (goals-focused) or mechanistic (action-focused) descriptions of targets' actions. Neural structures that play key roles in inferring goals and intentions from others' observed or imagined actions include temporo-parietal junction, ventral premotor cortex and extrastriate body area. We hypothesized that these regions play a role in action identification as well. Data collected using functional magnetic resonance imaging (fMRI) confirmed our predictions that activity in ventral premotor cortex and middle temporal gyrus near the extrastriate body area varies both as a function of the valence of the target and the extent to which actions are identified as goal-directed. In addition, the inferior parietal lobule is preferentially engaged when participants identify the actions of mentalized targets. Functional connectivity analyses suggest support from other regions, including the medial prefrontal cortex and amygdala, during mentalization. We found correlations between action identification and Autism Quotient scores, suggesting that understanding the neural correlates of action identification may enhance our understanding of the underpinnings of essential social cognitive processes.

The role of thought suppression in building mental blocks.

This research examined the role of thought suppression in the formation of mental blocks. In Experiment 1, participants were asked to generate a series of creative associates for two target words after initially suppressing a word that was semantically related to one of the two target words. Participants produced fewer responses, and experienced a greater sensation of being mentally blocked, when attempting to produce associates for the target word that was semantically related to the suppressed word. In Experiment 2, participants either thought about or suppressed a series of words prior to completing a word fragment completion task. Each word either corresponded exactly to one of the word fragment solutions (target primes) or resembled one of the solutions but was slightly different in its orthographic properties (negative primes). Participants performed most poorly on the items for which they had initially suppressed negative primes.

Accurate identification of fear facial expressions predicts prosocial behavior.

The fear facial expression is a distress cue that is associated with the provision of help and prosocial behavior. Prior psychiatric studies have found deficits in the recognition of this expression by individuals with antisocial tendencies. However, no prior study has shown accuracy for recognition of fear to predict actual prosocial or antisocial behavior in an experimental setting. In 3 studies, the authors tested the prediction that individuals who recognize fear more accurately will behave more prosocially. In Study 1, participants who identified fear more accurately also donated more money and time to a victim in a classic altruism paradigm. In Studies 2 and 3, participants' ability to identify the fear expression predicted prosocial behavior in a novel task designed to control for confounding variables. In Study 3, accuracy for recognizing fear proved a better predictor of prosocial behavior than gender, mood, or scores on an empathy scale.

What do I think you're doing? Action identification and mind attribution.

The authors examined how a perceiver's identification of a target person's actions co-varies with attributions of mind to the target. The authors found in Study 1 that the attribution of intentionality and cognition to a target was associated with identifying the target's action in terms of high-level effects rather than low-level details. In Study 2, both action identification and mind attribution were greater for a liked target, and in Study 3, they were reduced for a target suffering misfortune. In Study 4, it was again found that action identification and mind attribution were greater for a liked target, but like that for the self or a liked other, positive actions were identified at higher levels than negative actions, with the reverse being true for disliked others. In Study 5, the authors found that instructing participants to adopt the target's perspective did not affect mind attribution but did lead to higher level identifications of the target's actions.

Dream rebound: the return of suppressed thoughts in dreams.

People spent 5 min before sleep at home writing their stream of thought as they suppressed thoughts of a target person, thought of the person, or wrote freely after mentioning the person. These presleep references generally prompted people to report increased dreaming about the person. However, suppression instructions were particularly likely to have this influence, increasing dreaming about the person as measured both by participants' self-ratings of their dreams and by raters' coding of mentions of the person in written dream reports. This effect was observed regardless of emotional attraction to the person.
