Advances in the pharmacological treatment of pathological gambling

In the present paper we discuss the current status of drug treatment for pathological gambling and the scientific rationales underlying the various pharmacological approaches. Specifically, we summarize the treatment study results of serotonin reuptake inhibitors, mood stabilizers, opioid antagonists, and atypical antipsychotics in pathological gambling. We also discuss dosage strategies, the duration of treatment, issues surrounding medication compliance, and approaches to treatment-refractory pathological gambling, such as pharmacological and behavioral augmentation.     

Neurodevelopment,impulsivity, and adolescent gambling

The prevalence of problem and pathological gambling in adolescence and young adulthood has been found to be two- to fourfold higher than in adulthood. Given that these high rates might predict future increases across all age groups, it is important to explore the causes of the elevated rates of problem and pathological gambling among youths. This article reviews evidence for a neurobiological basis for adolescent vulnerability to problem and pathological gambling behaviors. We propose that a common trait motif of impulsivity might underlie phenomenology of pathological gambling, commonly comorbid psychiatric disorders, and related aspects of adolescent behavior. Recent advances in understanding the brain mechanisms involved in motivation, reward, and decision-making allow a discussion of neural circuitry underlying impulsivity. Emerging data indicate that important neurodevelopmental events during adolescence occur in brain regions associated with motivation and impulsive behavior. We hypothesize that immaturity of frontal cortical and subcortical monoaminergic systems during normal neurodevelopment underlies adolescent impulsivity as a transitional trait-behavior. While these neurodevelopmental processes may confer advantage by promoting a learning drive for optimal adaptation to adult roles, they may also confer an increased vulnerability to addictive behaviors such as problem and pathological gambling. An exploration of the developmental changes in neural circuitry involved in impulse control has significant implications for understanding adolescent behaviors and treating problem and pathological gambling among youths.     

Prosody–face Interactions in Emotional Processing as Revealed by the Facial Affect Decision Task

Previous research employing the facial affect decision task (FADT) indicates that when listeners are exposed to semantically anomalous utterances produced in different emotional tones (prosody), the emotional meaning of the prosody primes decisions about an emotionally congruent rather than incongruent facial expression (Pell, M. D., Journal of Nonverbal Behavior, 29, 45–73). This study undertook further development of the FADT by investigating the approximate timecourse of prosody–face interactions in nonverbal emotion processing. Participants executed facial affect decisions about happy and sad face targets after listening to utterance fragments produced in an emotionally related, unrelated, or neutral prosody, cut to 300, 600, or 1000 ms in duration. Results underscored that prosodic information enduring at least 600 ms was necessary to presumably activate shared emotion knowledge responsible for prosody–face congruity effects. Marc D.

Unleashing the power of community to strengthen the well-being of children, youth, and families: an asset-building approach

Search Institute's decade-plus emphasis on the elements of positive human development and community approaches to asset building can make a meaningful contribution to the field of child welfare. The institute's framework of developmental assets identifies a set of interrelated experiences, relationships, skills, and values that are associated with reduced high-risk behaviors and increased thriving behaviors. Its community-building work emphasizes the human relations and developmental infrastructure children, youth, and families require for their health and well-being.     

Characteristics of Gambling Helpline Callers with Self-Reported Gambling and Alcohol Use Problems

The characteristics of problem gamblers calling the Connecticut Council on Problem Gambling (CCPG) gambling helpline during the years 2000–2001 (n = 960) were examined based on the presence or absence of self-reported alcohol use problems. A relatively low proportion of callers reported a problem with alcohol use (173/960 or 18.0%), and of those acknowledging an alcohol use problem, the majority reported a past rather than current problem (143/173 or 82.7%). A logistic regression analysis found that, as compared with problem gamblers denying any alcohol use problems, those reporting past or current alcohol use problems were more likely to be male and more frequently acknowledged problems with more forms of gambling, suicide attempts related to gambling, arrests secondary to gambling, daily tobacco use, drug use problems, prior substance abuse treatment, and family histories positive for alcohol and drug use problems. The findings highlight the strong relationship between alcohol use problems and other substance use problems, and suggest that problem gamblers with as compared with those without alcohol use problems demonstrate greater problems in multiple areas (arrest, attempted suicide) linked by impaired impulse control.Please address correspondence to Marc N.

Social and Didactic Parenting Behaviors and Beliefs Among Japanese American and South American Mothers of Infants

Mothers of Japanese or South American ancestry living in the United States participated. Similarities and differences in mothers' social and didactic parenting behaviors and beliefs, and direct relations between behaviors and beliefs in these 2 domains of interaction, are reported. In accordance with a common collectivist orientation, Japanese American and South American mothers reported that they engaged in more social than didactic interactions with their infants, and South American mothers more than Japanese American mothers. However, in actuality, both of these acculturating groups engaged in more didactic than social behaviors with their infants and did so for longer periods of time. Not surprisingly, no belief‐behavior relations emerged in either group.     

Covariance Models For Latent Structure In Longitudinal Data

We present several approaches to modeling latent structure in longitudinal studies when the covariance itself is the primary focus of the analysis. This is a departure from much of the work on longitudinal data analysis, in which attention is focused solely on the cross-sectional mean and the influence of covariates on the mean. Such analyses are particularly important in policy-related studies, in which the heterogeneity of the population is of interest. We describe several traditional approaches to this modeling and introduce a flexible, parsimonious class of covariance models appropriate to such analyses. This class, while rooted in the tradition of mixed effects and random coefficient models, merges several disparate modeling philosophies into what we view as a hybrid approach to longitudinal data modeling. We discuss the implications of this approach and its alternatives especially on model interpretation. We compare several implementations of this class to more commonly employed mixed effects models to describe the strengths and limitations of each. These alternatives are compared in an application to long-term trends in wage inequality for young workers. The findings provide additional guidance for the model formulation process in both statistical and substantive senses.     

Prospect theory for continuous distributions

We extend the original form of prospect theory by Kahneman and Tversky from finite lotteries to arbitrary probability distributions, using an approximation method based on weak-⋆ convergence. The resulting formula is computationally easier than the corresponding formula for cumulative prospect theory and makes it possible to use prospect theory in future applications in economics and finance. Moreover, we suggest a method how to incorporate a crucial step of the “editing phase” into prospect theory and to remove in this way the discontinuity of the original model.
