Early Negative Affect Predicts Anxiety, not Autism, in Preschool Boys with Fragile X Syndrome

Children with fragile X syndrome (FXS) face high risk for anxiety disorders, yet no studies have explored FXS as a high-risk sample for investigating early manifestations of anxiety outcomes. Negative affect is one of the most salient predictors of problem behaviors and has been associated with both anxiety and autistic outcomes in clinical and non-clinical pediatric samples. In light of the high comorbidity between autism and anxiety within FXS, the present study investigates the relationship between longitudinal trajectories of negative affect (between 8 and 71 months) and severity of anxiety and autistic outcomes in young males with FXS (n?=?25). Multilevel models indicated associations between elevated anxiety and higher fear and sadness, lower soothability, and steeper longitudinal increases in approach. Autistic outcomes were unrelated to negative affect. These findings suggest early negative affect differentially predicts anxiety, not autistic symptoms, within FXS. Future research is warranted to determine the specificity of the relationship between negative affect and anxiety, as well as to explore potential moderators. Characterizing the relationship between early negative affect and anxiety within FXS may inform etiology and treatment considerations specific to children with FXS, as well as lend insight into precursors of anxiety disorders in other clinical groups and community samples.     

Mood-congruent true and false memory: Effects of depression

The Deese/Roediger-McDermott paradigm was used to investigate the effect of depression on true and false recognition. In this experiment true and false recognition was examined across positive, neutral, negative, and depression-relevant lists for individuals with and without a diagnosis of major depressive disorder. Results showed that participants with major depressive disorder falsely recognised significantly more depression-relevant words than non-depressed controls. These findings also parallel recent research using recall instead of recognition and show that there are clear mood congruence effects for depression on false memory performance.     

A Randomized Trial of Two Promising Computer-Based Interventions for Students with Attention Difficulties

Few studies have examined whether attention can be improved with training, even though attention difficulties adversely affect academic achievement. The present study was a randomized-controlled trial evaluating the impact of Computerized Attention Training (CAT) and Computer Assisted Instruction (CAI) on attention and academic performance in 77 inattentive first graders. Students receiving either intervention were more likely than controls to show a moderate decline in teacher rated attention problems in first grade. Students receiving CAI also showed gains in reading fluency and in teacher ratings of academic performance. Intervention effects for attention were absent by second grade largely because attention problems declined in all groups. However, post hoc analyses indicated potential longer-term benefits for children with 6 or more inattentive symptoms at baseline. Persistent attention problems were associated with poorer academic performance in multiple domains. Results provide initial evidence that CAT and CAI can improve children’s attention in the classroom - and support additional studies to determine whether more clinically significant benefits are attainable.     

First Annual Diversity Challenge: “How to Survive Teaching Courses on Race and Culture”

The authors discuss the highlights of the 1st annual Diversity Challenge held October 11–12, 2001, at Boston College, Boston, MA. The Challenge's general focus was preparing educators to cope with the resistances encountered when they teach about race and ethnic culture. This introduction (a) provides an overview of the proceedings, (b) summarizes themes of presentations and articles selected, and (c) offers recommendations for subsequent events. Los autores analizan el primer Reto de Diversidad, que tuvo lugar del 11 al 12 de octubre, 2001, en Boston College, Boston, Massachusetts. El próposito del reto fue preparar a los profesores para que puedan enfrentar las dificultades que resultan de enseñar los temas de la raza y la cultura étnica. Esta introducción (a) da un breve resumen de los procedimientos, (b) resume los temas de las presentaciones y los ensayos seleccionados, y, (c) sugiere recommendaciones para eventos posteriores.     

Modern Molar Behaviorism And Theoretical Behaviorism: Religion And Science.

Baum and staddon disagree on the status of internal states in behavior analysis. Baum advocates molar behaviorism, treating behavior in temporally extended segments and so avoiding the need for internal states. Staddon argues that internal states merely represent the effects of different histories and that their use brings behavior analysis in line with the established sciences. The dispute is one form of the age‐old molar—molecular controversy that characterized Aristotle's disagreement with Plato. Both molar and molecular analyses have their place, but molar behaviorism may apply more naturally to a variety of phenomena, ranging from the matching law and avoidance learning to socalled “higher mental processes.” When molecular analysis involves internal states, as in Staddon's Theoretical Behaviorism (or New Behaviorism), misunderstanding will be inevitable and behaviorism will be seen as one more instance of the mediational theories in which psychology has long been mired. Such theories have long dominated the physical sciences, where their usefulness is indisputable, but psychology is far behind the physical sciences and nonmediational molar behaviorism better suits a discipline that lacks the methods and the data of the established sciences.     

Etiological contributions to heavy drinking from late adolescence to young adulthood

The authors examined genetic and environmental contributions to stability and change in heavy drinking from late adolescence to young adulthood in a sample of 1,152 twin pairs. In men, heavy drinking was similarly heritable at ages 17 (h2=.57) and 20 (h2=.39), and its stability owed primarily to common genetic factors. In women, heavy drinking was less heritable than in men at ages 17 (h2=.18) and 20 (h2=.30) and its stability was primarily due to enduring shared environmental influences. P3 amplitude, an event-related brain potential marker of alcoholism risk, was less predictive of heavy drinking in women than in men, providing further support for the proposition that biological factors have less impact on heavy drinking in young adult women than in young adult men.     

Measuring direct and indirect aggression: behavior of is there a response bias?

Critics of self-report methods suggest that participants are likely to underreport their own negative behaviors given concerns about social desirability. The current study examined the problem of self-report bias by comparing individuals' estimates of their own and others' aggressive behavior. Undergraduate students (95 women, 50 men) completed the Richardson Conflict Response Questionnaire with regard to either their own behavior or that of another person of the same sex. As expected, participants reported significantly less aggression for themselves than for others. However, self and other ratings showed the same pattern of sex differences. These results suggest that, although individuals may underreport their own aggressive behaviors, this tendency may not affect relationships among variables.     

A 12-Year Prospective Study of Patterns of Social Information Processing Problems and Externalizing Behaviors

This study investigated how discrete social information processing (SIP) steps may combine with one another to create distinct groups of youth who are characterized by particular patterns of SIP. SIP assessments were conducted on a community sample of 576 children in kindergarten, with follow-up assessments in grades 3, 8, and 11. At each age, four profiles were created, representing youth with no SIP problems, with early step SIP problems (encoding or making hostile attributions), with later step SIP problems (selecting instrumental goals, generating aggressive responses, or evaluating aggression positively), and with pervasive SIP problems. Although patterns of SIP problems were related to concurrent externalizing during elementary school, the consistency between cognition and future externalizing behavior was not as strong in elementary school as it was between grades 8 and 11. In some cases, youth characterized by the co-occurrence of problems in early and later SIP steps had higher externalizing scores than did youth characterized by problems in just one or the other.
