Orienting task effects on memory for presentation modality in children, young adults, and older adults.

Children (7 to 10 years), young adults (17 to 24 years), and older adults (55 to 77 years) were asked to learn three lists of words that were of mixed modality (half the words were visual, and half the words were auditory). With one list the subjects were asked a semantic orienting question; with another, a nonsemantic orienting question; and with a third, no orienting question. Half the subjects in each age group were also asked to remember the presentation modality of each word. Older adults remembered less information about modality than children and young adults did, and the variation in the type of orienting question--or the lack of one--affected modality identification. However, there was no Orienting Task x Age interaction for modality identification. The results of this study suggest that encoding modality information does not take place automatically--in any age group--but that explanations focusing on encoding strategies and effort are not likely to account for older adults' difficulties in remembering presentation modality.     

Personality and depression: a validation study of the Depressive Experience Questionnaire

This study investigated the validity of Blatt's model of depression as indicated by his operational measure of its constructs via the Depressive Experiences Questionnaire (DEQ; Blatt, D'Afflitti, & Quinlan, 1976). Hypothesized relations between the two relevant scales of the DEQ and Tellegen's (1982) Multidimensional Personality Questionnaire, (MPQ) were examined, Participants consisted of 195 women, including 67 hospitalized unipolar depressives, 77 never-hospitalized unipolar depressives, and 51 nonpsychiatric controls. Overall, the results partially supported the validity of the DEQ even though all participants were women and prior studies have indicated the DEQ's greater discriminative validity for men than for women. However, several of the most strongly predicted relations, such as between DEQ Self-Criticism and MPQ Achievement were not confirmed. Coherent, significant relations between scales of the two measures remained after partialling out the effects of severity of depression.     

Neuropsychological and MMPI correlates of patients' future employment characteristics

Previous research has suggested that patients' neuropsychological test scores correlate not only with neurologic status but also with their success in coping with some of the demands of daily living. This study investigated the utility of such laboratory test scores in predicting several vocational variables. Patients who had recieved neuropsychological evaluations were recontacted and questioned about their employment over the previous 6 mo. Of the 78 individuals who participated, 25 had been chronically unemployed. The remaining 53 were asked about job stability, hours worked, and wages earned, and were administered the Minnsota Job Requirements Questionnaire. Patients' scores on the Halstead-Reitan Battery, the WAIS and the MMPI were highly correlated with employment status (employed or chronically unemployed), income, and skills required on the jobs held. The results suggest that these tests may have clinical utility in assessing patients' employability, as well as the types of jobs for which they are suited.     

Negotiating false memories: interviewer and rememberer characteristics relate to memory distortion

In a recent study, more than half of the participants were led to create a partial or complete false memory for an emotional childhood event (e.g., serious animal attack). Using a subsample from that study, we examined the hypothesis that memory distortion is related to characteristics of interviewers and rememberers. The relations between susceptibility to memory distortion and (a) dissociation (Dissociative Experiences Scale) and (b) personality traits (NEO-Five Factor Inventory) were investigated. Results indicated that participants who exhibited memory distortion scored significantly higher on the dissociative scale than their counterparts who did not exhibit memory distortion. Further, susceptibility to memory distortion was associated with higher extraversion scores in interviewers and lower extraversion scores in participants. This pattern of findings suggests that false memories may derive from a social negotiation between particular interviewers and rememberers.     

Hunger, eating, and ill health

Humans and other warm-blooded animals living with continuous access to a variety of good-tasting foods tend to eat too much and suffer ill health as a result--a finding that is incompatible with the widely held view that hunger and eating are compensatory processes that function to maintain the body's energy resources at a set point. The authors argue that because of the scarcity and unpredictability of food in nature, humans and other animals have evolved to eat to their physiological limits when food is readily available, so that excess energy can be stored in the body as a buffer against future food shortages. The discrepancy between the environment in which the hunger and eating system evolved and the food-replete environments in which many people now live has led to the current problem of overconsumption existing in many countries. This evolutionary perspective has implications for understanding the etiology of anorexia nervosa.     

Electropalatographic and spectrographic descriptions of allophonic variants of /1/

Prevocalic and postvocalic /1/ were investigated in three adult subjects utilizing a combination of electropalatographic and acoustic techniques. Results indicated that prevocalic /1/ was characterized by both alveolar and lateral lingua-palatal contact, while postvocalic /1/ was primarily alveolar contact only. Acoustically, prevocalic /1/ had a lower first formant and higher second formant than postvocalic /1/. In addition, the second and third formants were often weak or absent for prevocalic but not postvocalic /1/. Vowel context had a greater effect on the electropalatographic and acoustic characteristics of prevocalic than postvocalic /1/. Models that relate physiological and acoustical aspects of speech were utilized to account for the observed results.     

Examining the Long-Term Effects of a Domestic Violence Training for Educators

Domestic violence affects not only the victims and perpetrators, but also children living in these households. This study examined the long-term effects of a training presented to all employees working in 22 different rural school districts (N = 556). Quantitative and qualitative data were collected to determine the long-term impact of the training. After approximately 4 years, the staff who had received the training reported that they had significantly more confidence in handling families dealing with domestic violence; however, both groups reported similar levels of general knowledge of the topic. Recommendations for training school personnel are provided along with key elements for replicating the training.     

Rethinking the biopsychosocial model of health: Understanding health as a dynamic system

The biopsychosocial model has dominated research and theory in health psychology. This article expands the biopsychosocial model by applying systems theories proposed by developmental scholars, including Bronfenbrenner's ecological models and Sameroff's transactional model, as well as contemporary philosophical work on dynamic systems. The proposed dynamic biopsychosocial model construes human health as a product of the reciprocal influences of biological, psychological, interpersonal, and macrosystem contextual dynamics that unfold over personal and historical time. The importance, or centrality, of these influences varies within a person over time. The model is explicated using two hypothetical case studies derived from existing interdisciplinary health research. Implications for health, theory, research, and policy are discussed.     

Transition from School to Adult Life: Empowering Youth Through Community Ownership and Accountability

The evolution of transition services for youth with disabilities illustrates the transformation that has occurred from a systems-driven to a youth-centered support approach. This article documents how this shift has occurred. We review research that has influenced the direction of national policies and practices. A chronology of the policies that best represent the seminal foundation for current transition best practices for youth with emotional disturbance (ED) is presented. The field of special education led the way toward articulating the new vision for providing transition support by defining services as the coordination of multiple systems to address life domains (e.g., post-secondary education, employment, independent living, and community adjustment). Promising practices, within the context of the conversion to an ecological model of support that contributes to youth self-determination, include utilization of a youth-centered, strengths-based approach to transition planning, beginning in the middle school years. There remain significant barriers to adoption of the practices that may best support the successful transition of youth. These include lack of coordinated efforts across systems, socioeconomic, and community factors. Committed actions by government, the business sector, and private citizens are essential to address these challenges.     

Neural bases of moderation of cortisol stress responses by psychosocial resources

Psychosocial resources have been tied to lower psychological and biological responses to stress. The present research replicated this relationship and extended it by examining how differences in dispositional reactivity of certain neural structures may underlie this relationship. Two hypotheses were examined: (a) psychosocial resources are tied to decreased sensitivity to threat and/or (b) psychosocial resources are associated with enhanced prefrontal inhibition of threat responses during threat regulation. Results indicated that participants with greater psychosocial resources exhibited significantly less cortisol reactivity following a stress task, as predicted. Analyses using functional magnetic resonance imaging revealed that psychosocial resources were associated with greater right ventrolateral prefrontal cortex and less amygdala activity during a threat regulation task but were not associated with less amygdala activity during a threat sensitivity task. Mediational analyses suggest that the relation of psychosocial resources to low cortisol reactivity was mediated by lower amygdala activity during threat regulation. Results suggest that psychosocial resources are associated with lower cortisol responses to stress by means of enhanced inhibition of threat responses during threat regulation, rather than by decreased sensitivity to threat.
