Positive overgeneralization and Behavioral Approach System (BAS) sensitivity interact to predict prospective increases in hypomanic symptoms: a behavioral high-risk design

Recent work has identified Behavioral Approach System (BAS) sensitivity as a risk factor for the first onset and recurrence of mood episodes in bipolar disorder, but little work has evaluated risk factors for the prospective development of hypomanic symptoms in individuals at risk for, but without a history of, bipolar disorder. The present study used a prospective behavioral high-risk design to evaluate the impact of positive overgeneralization, a cognitive correlate of risk for hypomania, on hypomanic symptoms in individuals with high vs. moderate BAS sensitivity, but without a history of mood elevation. Hierarchical linear regressions indicated that upward positive overgeneralization and BAS sensitivity interacted to predict increased levels of hypomanic symptoms at follow-up, controlling for initial hypomanic symptoms. The pattern of this interaction was such that positive overgeneralization predicted higher levels of hypomanic symptoms among high-BAS, but not moderate-BAS, individuals. Thus, the self-reported tendency to experience grandiose increases in confidence following success may confer additional risk for mood elevation among individuals already at risk for developing bipolar disorder. Potential implications for prevention and treatment are discussed.     

Forest before trees? It depends where you look

Because it may be deduced from the more elementary principles of visual processing, global precedence (Navon, 1977) is not a primary perceptual principle. Subjects were presented with a large letter made out of small ones and asked to make an identification response on the basis of either the large or small letter. When fixation was controlled to provide adequate stimulation from the small letter, there was no difference in reaction time (RT) between the large and small targets. Also, there was no difference in interference due to response incompatibility of the unattended letter based on target size. However, when the stimulus was presented peripherally, unpredictably to the right or left of fixation, RT was faster to the large target and interference was substantially greater for the small target. Functions for the development of associative strength and associative interference are presented. Global precedence is dependent on factors tending to degrade small stimuli more than large ones.     

Relationships among accumulated lifetime life events,prosocial skills,and behavior problems in elementary school children

Relationships among life events, prosocial skills, and behavior problems for 91 first through fourth grade children were examined. The data were based on mothers' reports of their children's lifetime life events, current prosocial skills, and current behavior problems. Higher prosocial skills scores significantly predicted lower Externalizing behavior problem scores. Higher weighted life events scores significantly predicted higher Internalizing behavior problem scores. The weighted life event scores×prosocial skills scores interaction did not significantly predict either Externalizing or Internalizing behavior problem scores. The more parsimonious main effects conceptualization suggests that life events and prosocial skills are orthogonal in young, elementary school children.     

A test of an interactive model of bulimic symptomatology in adult women

An interactive model of bulimic symptom development, first suggested by Vohs et al. (1999), was tested in adult women (mean age = 45.19). The following hypothesis was examined in a longitudinal design over 2.5 years: Women high in perfectionism, low in self-esteem, and who perceive themselves as overweight would be the most likely to experience an increase in bulimic symptoms. Results supported the model with regard to maintenance and exacerbation, but not onset, of bulimic symptoms. Furthermore, the interactive model was tested to see if it showed specificity to bulimic, versus depressive or anxious, symptoms. Some support for the model's specificity to bulimic symptoms was observed; however, the increase of anxious symptoms was also observed. Clinical and theoretical implications are discussed.     

Scale structure: processing minimum standard and maximum standard scalar adjectives

Gradable adjectives denote a function that takes an object and returns a measure of the degree to which the object possesses some gradable property [Kennedy, C. (1999). Projecting the adjective: The syntax and semantics of gradability and comparison. New York: Garland]. Scales, ordered sets of degrees, have begun to be studied systematically in semantics [Kennedy, C. (to appear). Vagueness and grammar: the semantics of relative and absolute gradable predicates. Linguistics and Philosophy; Kennedy, C. and McNally, L. (2005). Scale structure, degree modification, and the semantics of gradable predicates. Language, 81, 345-381; Rotstein, C., and Winter, Y. (2004). Total adjectives vs. partial adjectives: scale structure and higher order modifiers. Natural Language Semantics, 12, 259-288.]. We report four experiments designed to investigate the processing of absolute adjectives with a maximum standard (e.g., clean) and their minimum standard antonyms (dirty). The central hypothesis is that the denotation of an absolute adjective introduces a 'standard value' on a scale as part of the normal comprehension of a sentence containing the adjective (the "Obligatory Scale" hypothesis). In line with the predictions of Kennedy and McNally (2005) and Rotstein and Winter (2004), maximum standard adjectives and minimum standard adjectives systematically differ from each other when they are combined with minimizing modifiers like slightly, as indicated by speeded acceptability judgments. An eye movement recording study shows that, as predicted by the Obligatory Scale hypothesis, the penalty due to combining slightly with a maximum standard adjective can be observed during the processing of the sentence; the penalty is not the result of some after-the-fact inferencing mechanism. Further, a type of 'quantificational variability effect' may be observed when a quantificational adverb (mostly) is combined with a minimum standard adjective in sentences like "The dishes are mostly dirty", which may receive either a degree interpretation (e.g., 80% dirty) or a quantity interpretation (e.g., 80% of the dishes are dirty). The quantificational variability results provide suggestive support for the Obligatory Scale hypothesis by showing that the standard of a scalar adjective influences the preferred interpretation of other constituents in the sentence.     

The ABCs of depression: integrating affective, biological, and cognitive models to explain the emergence of the gender difference in depression

In adulthood, twice as many women as men are depressed, a pattern that holds in most nations. In childhood, girls are no more depressed than boys, but more girls than boys are depressed by ages 13 to 15. Although many influences on this emergent gender difference in depression have been proposed, a truly integrated, developmental model is lacking. The authors propose a model that integrates affective (emotional reactivity), biological (genetic vulnerability, pubertal hormones, pubertal timing and development) and cognitive (cognitive style, objectified body consciousness, rumination) factors as vulnerabilities to depression that, in interaction with negative life events, heighten girls' rates of depression beginning in adolescence and account for the gender difference in depression.     

Is there a universal positivity bias in attributions? A meta-analytic review of individual, developmental, and cultural differences in the self-serving attributional bias

Researchers have suggested the presence of a self-serving attributional bias, with people making more internal, stable, and global attributions for positive events than for negative events. This study examined the magnitude, ubiquity, and adaptiveness of this bias. The authors conducted a meta-analysis of 266 studies, yielding 503 independent effect sizes. The average d was 0.96, indicating a large bias. The bias was present in nearly all samples. There were significant age differences, with children and older adults displaying the largest biases. Asian samples displayed significantly smaller biases (d = 0.30) than U.S. (d = 1.05) or Western (d = 0.70) samples. Psychopathology was associated with a significantly attenuated bias (d = 0.48) compared with samples without psychopathology (d = 1.28) and community samples (d = 1.08). The bias was smallest for samples with depression (0.21), anxiety (0.46), and attention-deficit/hyperactivity disorder (0.55). Findings confirm that the self-serving attributional bias is pervasive in the general population but demonstrates significant variability across age, culture, and psychopathology.     

Group Intervention Studies in the Cognitive Rehabilitation of Individuals with Traumatic Brain Injury: Challenges Faced by Researchers

There are many factors to consider in designing and interpreting group studies. These include both analytic considerations, such as the selection of valid and reliable outcome measures, and subjective considerations, such as the selection of outcomes that are perceived to be important to participants and researchers. In this paper, we review key issues to consider in the design of group studies in neurorehabilitation, using problem-solving studies in traumatic brain injury as an example.     

Role of Parenting and Maltreatment Histories in Unipolar and Bipolar Mood Disorders: Mediation by Cognitive Vulnerability to Depression

In this article, we review empirical research on the role of individuals' parenting and maltreatment histories as developmental antecedents for symptoms and diagnosable episodes of unipolar and bipolar spectrum disorders. Our review is focused on the following three overarching questions: (1) Do negative parenting and a history of maltreatment contribute risk to symptoms or diagnosable episodes of unipolar and bipolar disorders? (2) Are the associations of negative parenting and maltreatment histories with bipolar disorders similar to those for unipolar depression? and (3) Are the associations between negative parenting and maltreatment histories and unipolar and bipolar symptoms or disorders mediated by cognitive vulnerability to depression? We begin by discussing the methodological requirements for demonstrating a psychosocial risk factor and the methodological issues that plague the parenting and maltreatment literatures. Next, we review the extant studies on the role of parenting histories in unipolar and bipolar disorders. We consider the specificity and possible moderators of the parenting-mood disorder relationship, as well as cognitive vulnerability to depression as a mediator of this relationship. Then, we review studies on the association of maltreatment histories with unipolar and bipolar disorders and the role of cognitive vulnerability to depression as a mediator of this association. We conclude with an assessment of the state of the parenting and maltreatment literatures in unipolar and bipolar disorder with regard to our guiding questions.
