Psychological and health problems in a geographically proximate population time-sampled continuously for three months after the September 11th, 2001 terrorist incidents

This study assessed the mental and physical health status and psychological problems related to the September 11th terrorist incidents among a representative sample of adults living near New York City, using continuously time-sampled data collected throughout 2001. Prevalence estimates for poor mental or physical health after September 11th (October through December) were comparable to those for the entire year of 2001 (i.e. approximately 33%). Psychological problems related to the terrorist incidents were reported by more than half of the respondents, and appeared to peak in prevalence approximately two to three months following the incidents, followed by a decline in the next month and subsequent year. Poor mental health, female gender, media re-exposure, and ongoing or increased alcohol use were risk factors for psychological problems, while older age (65+ years old) and being married were protective factors. Risk factors for poor physical and mental health or psychological problems were generally stable over the three-month period following September 11th, but some changes were identified consistent with stage models of post-disaster psychological adjustment. Implications are discussed for using continuous time-sampling as a strategy to research patterns of relatively acute stress-related sequelae of terrorism in populations whose members are affected despite primarily not having been at the disaster epicenter.     

Recommendations from Multi-disciplinary Focus Groups on Cascade Testing and Genetic Counseling for Fragile X-associated Disorders

The purpose of this paper is to report the outcome of a collaborative project between the Fragile X Research and Treatment Center at the Medical Investigation of Neurodevelopmental Disorders (M.I.N.D.) Institute at the University of California at Davis, the National Fragile X Foundation (NFXF), and the Centers for Disease Control and Prevention (CDC). The objective of this collaboration was to develop and disseminate protocols for genetic counseling and cascade testing for the multiple disorders associated with the fragile X mental retardation 1 (FMR1) mutation. Over the last several years, there has been increasing insight into the phenotypic range associated with both the premutation and the full mutation of the FMR1 gene. To help develop recommendations related to screening for fragile X-associated disorders, four, two day advisory focus group meetings were conducted, each with a different theme. The four themes were: (1) fragile X-associated tremor/ataxia syndrome (FXTAS); (2) premature ovarian failure (POF) and reproductive endocrinology; (3) psychiatric, behavioral and psychological issues; and (4) population screening and related ethical issues.     

Separating cognitive capacity from knowledge: a new hypothesis

We propose that working memory and reasoning share related capacity limits. These limits are quantified in terms of the number of items that can be kept active in working memory, and the number of interrelationships between elements that can be kept active in reasoning. The latter defines the complexity of reasoning problems and the processing loads they impose. Principled procedures for measuring, controlling or limiting recoding and other strategies for reducing memory and processing loads have opened up new research opportunities, and yielded orderly quantification of capacity limits in both memory and reasoning. We argue that both types of limit might be based on the limited ability to form and preserve bindings between elements in memory.     

The long‐term effects of institutional rearing,foster care intervention and disruptions in care on brain electrical activity in adolescence

Exposure to early psychosocial deprivation as a result of institutional care disrupts typical brain development. The Bucharest Early Intervention Project (BEIP) is the first longitudinal study to investigate the neurodevelopment of institutionalized infants randomized to a foster care (FCG) intervention versus care as usual (CAUG). Here, we present findings from a follow‐up assessment of brain electrical activity as indexed by resting EEG at age 16 years. In addition, we examined the effects of disruption of foster care placement (e.g. the number of moves among foster care placements) on brain electrical activity. Resting‐state EEG was collected from 48 CAUG, 46 FCG and 48 never institutionalized (NIG) control participants. Absolute (µV²) and relative (proportion) power were computed from eyes closed, resting EEG data for theta, alpha and beta frequency bands. The CAUG displayed higher relative theta and lower relative alpha power compared to the FCG at 16 years of age. The FCG showed brain activity comparable to the NIG. The results further showed that disruptions following the original foster care placement had an adverse effect on brain electrical activity. Within the foster care group, there were no effects of age of placement on EEG power. Placement of children who have experienced early institutional rearing into stable foster care settings ensure long‐term improvement in brain functioning.     

Motivational systems of agonistic behavior in muroid rodents: A comparative review and neural model

The data on agonistic behavior of muroid rodents that have been obtained from field observations and laboratory experiments are reviewed and compared in terms of a hypothetical model of the neural organization of these behaviors. The neural model has been presented elsewhere and is used here only as a way to organize the data. The data are organized in terms of four hypothetical motivational systems: Offense, defense, submission, and patrol/marking. The various behaviors are considered as motor patterns and are compared and analyzed in terms of the proposed motivating, releasing, and directing stimuli of the motivational systems. Interactions and overlaps between the motivational systems are also considered. It is concluded that the organization of agonistic behavior may be similar across all species of muroid rodents. Generalizations are complicated by the profound effects of ontogenetic factors. Four categories of behaviors differ from species to species: Scent-marking, submissive behaviors, threat behaviors, and alarm signals. The possible phylogenetic and ontogenetic factors in these differences are considered.     

Task instructions for persons with severe intellectual disability: reducing the number of instruction occasions after the acquisition phase

During the first part of the study, eight tasks were taught to four participants with severe intellectual disability. A portable computer‐aided system was used that presented one pictorial instruction per task step, individually. During the second part of the study, the same computer‐aided system was used but the number of instruction occasions available for the tasks was reduced. In one condition, the system presented all the step instructions but mostly in small clusters rather than individually. In another condition, the system presented only some of the instructions. Data for the first part of the study showed that the participants managed to perform 83–97% of the task steps correctly. Data for the second part of the study showed that the condition in which instructions were clustered was more effective in maintaining high percentages of correct performance. Implications of the findings are discussed. Copyright © 1999 John Wiley & Sons, Ltd.     

Emotional content of talk to the fetus and healthy coping behaviors during pregnancy

This study examined whether the emotional content of talk to the self and to the fetus were related to health behaviors and psychosocial factors during pregnancy. One hundred fifty-two third-trimester pregnant women attending childbirth preparation classes completed a survey containing the Intrapersonal Communication Questionnaire, which sampled spontaneous talk to the self (self-talk) and to the fetus (baby-talk), and which yielded ratings of emotional valence of talk quotations into positive, negative, neutral, and mixed categories; the Rosenberg Self-Esteem Scale; and indices for life stress, social support, and consumption behaviors. Baby-talk was more positive whereas self-talk was more negative, or emotionally distressed. More mixed baby-talk occurred with more medicine consumption, and medicine consumption was also related to lower self-esteem and more life stress. More negative baby-talk occurred when cigarette and caffeine consumption was higher. Emotional content of maternal talk to the fetus might indicate development of maternal bonding, and specific emotional contents might be related to health-relevant coping behaviors, for example, consumption of cigarettes and caffeine. Clinical implications for maternal behaviors after birth are discussed.
