Reactive and proactive aggression: stability of constructs and relations to correlates

The authors examined short-term temporal stability of reactive and proactive aggression, as well as short-term consistency of differential relations of reactive versus proactive aggression to 4 correlates. The authors used parent, teacher, peer, and self-report measures twice across 1 year to assess reactive aggression, proactive aggression, hyperactivity, social skills, anger expression, and depressive symptoms of 2nd-grade boys and girls (N = 57). Both subtypes of aggression remained stable across the year, even when the other subtype of aggression was explained at each assessment. Reactive aggression, but not proactive aggression, was consistently positively related to hyperactivity, poor social skills, and anger expression at each assessment.     

Processing Speed Deficits in Attention Deficit/Hyperactivity Disorder and Reading Disability

The goal of the current study was to test whether deficits in processing speed (PS) may be a shared cognitive risk factor in reading disability (RD) and Attention Deficit/Hyperactivity Disorder (ADHD), which are known to be comorbid. Literature on ADHD and RD suggests that deficits on tasks with a speeded component are seen in both of these disorders individually. The current study examined a wide range of speeded tasks in RD, ADHD, comorbid RD+ADHD, and a control group to test whether RD and ADHD have similar profiles of PS deficits, and whether these deficits are shared by the two disorders. The results suggest that a general PS deficit exists in both clinical groups compared to controls, although children with RD demonstrate greater PS deficits than children with ADHD. Two tests (underadditivity and partial correlations) were conducted to test whether these PS deficits are shared. Since we found that PS deficits were underadditive in the comorbid group and that partialling PS reduced the correlation between RD and ADHD, it appears that PS is a shared cognitive risk factor that may help explain the comorbidity of these two disorders.     

A cognitive architecture that combines internal simulation with a global workspace

This paper proposes a brain-inspired cognitive architecture that incorporates approximations to the concepts of consciousness, imagination, and emotion. To emulate the empirically established cognitive efficacy of conscious as opposed to non-conscious information processing in the mammalian brain, the architecture adopts a model of information flow from global workspace theory. Cognitive functions such as anticipation and planning are realised through internal simulation of interaction with the environment. Action selection, in both actual and internally simulated interaction with the environment, is mediated by affect. An implementation of the architecture is described which is based on weightless neurons and is used to control a simulated robot.     

Anxiety symptomatology: the association with distress tolerance and anxiety sensitivity

Research focused on psychological risk factors for anxiety psychopathology has led to better conceptualization of these conditions as well as pointed toward preventative interventions. Anxiety sensitivity (AS) has been well-established as an anxiety risk factor, while distress tolerance (DT) is a related construct that has received little empirical exploration within the anxiety psychopathology literature. The current investigation sought to extend the existing literature by examining both DT and the relationship between DT and AS across a number of anxiety symptom dimensions, including panic, generalized anxiety, social anxiety, and obsessive-compulsive anxiety. Participants (N = 418) completed a number of measures that assessed DT, AS, anxiety symptomatology, and negative affect. Findings indicated that DT was uniquely associated with panic, obsessive compulsive, general worry, and social anxiety symptoms, but that DT and AS were not synergistically associated with each of these symptom dimensions. These findings indicate that an inability to tolerate emotional distress is associated with an increased vulnerability to experience certain anxiety symptoms.     

Does Childhood Executive Function Predict Adolescent Functional Outcomes in Girls with ADHD?

We prospectively followed an ethnically and socioeconomically diverse sample of preadolescent girls with ADHD (n = 140) and matched comparison girls (n = 88) over a period of 5 years, from middle childhood through early/mid-adolescence. Our aim was to examine the ability of measures of childhood executive function (EF) to predict functional outcomes in adolescence. Measures of neuropsychological functioning comprised the childhood predictors, with academic, social, and global functioning serving as adolescent criterion measures. Results indicated that childhood EF predicted (a) academic achievement and social functioning across our entire sample (independent of diagnostic group status) and (b) global functioning only in girls with ADHD (independent of IQ). These results highlight the non-specificity of EF deficits and suggest the importance of assessing and developing interventions that target EF impairments, particularly in those at high-risk for negative outcomes, in order to prevent long-term difficulties across a range of important functional domains.     

Too exhausted to remember: Ego depletion undermines subsequent event‐based prospective memory

Past research has consistently found that people are likely to do worse on high‐level cognitive tasks after exerting self‐control on previous actions. However, little has been unraveled about to what extent ego depletion affects subsequent prospective memory. Drawing upon the self‐control strength model and the relationship between self‐control resources and executive control, this study proposes that the initial actions of self‐control may undermine subsequent event‐based prospective memory (EBPM). Ego depletion was manipulated through watching a video requiring visual attention (Experiment 1) or completing an incongruent Stroop task (Experiment 2). Participants were then tested on EBPM embedded in an ongoing task. As predicted, the results showed that after ruling out possible intervening variables (e.g. mood, focal and nonfocal cues, and characteristics of ongoing task and ego depletion task), participants in the high‐depletion condition performed significantly worse on EBPM than those in the low‐depletion condition. The results suggested that the effect of ego depletion on EBPM was mainly due to an impaired prospective component rather than to a retrospective component.     

Learning how to help others: Two-year-olds’ social learning of a prosocial act

Engaging in prosocial behaviors (acts that benefit others) is associated with many positive outcomes in children, including the development of positive peer relationships, academic achievement, and good psychological functioning. This study examined the social learning mechanisms toddlers use to acquire prosocial behaviors. This brief report presents a new experimental procedure in which 2-year-olds (28–32 months, N = 30) saw a video of an adult performing a novel prosocial behavior in response to another person’s distress. Children then had the opportunity to imitate and implement the behavior in response to their own parent’s physical distress. Children who saw the video were more likely to perform the novel action and to display non-demonstrated prosocial behaviors relative to (a) children who did not view the video but saw a parent in distress and (b) children who saw the video but witnessed their mother engage in a neutral activity. These results suggest that toddlers imitate and emulate prosocial behaviors for social interaction and that children can apply such behaviors in appropriate situations.     

The Push for More Challenging Texts: An Analysis of Early Readers’ Rate,Accuracy, and Comprehension

The purpose of the study was to examine the relationship between the challenge level of text and early readers’ reading comprehension. This relationship was also examined with consideration to students’ word recognition accuracy and reading rate. Participants included 636 students, in Grades 1–3, in a southeastern state. Results suggest that students reading texts well above their actual grade levels, even with sufficient accuracy scores, scored significantly lower on comprehension than students reading texts at their actual grade level. This result also held regardless of students’ reading rates. Findings signal the importance of considering text level during instruction and suggest some caution is warranted when pushing students into texts well above their grade levels.     

SEQUENTIAL APPLICATION OF CAREGIVER TRAINING TO IMPLEMENT PEDIATRIC FEEDING PROTOCOLS

The purpose of this study was to evaluate the effectiveness of current caregiver training practices by implementing training components sequentially, to teach parents mealtime protocols. A multiple baseline design was implemented across two caregiver dyads. Therapist‐fed meals were conducted prior to training to identify an effective intervention to increase food acceptance and decrease food refusal. The package consisted of seven components: observation, written and verbal protocol review, video review, structured observation, modeling, role play, and immediate feedback. Correct implementation of mealtime protocols, by caregivers, were evaluated throughout the training process by having caregivers conduct meal sessions following each training component to determine if additional training was necessary. Results showed that the training procedures were effective in teaching caregivers to implement mealtime protocols, and systematic introduction of the training components produced systematic and incremental changes in correct caregiver implementation. In addition, all participants completed training without requiring all seven training components. Copyright © 2012 John Wiley & Sons, Ltd.
