Personality and Health, Subjective Well-Being, and Longevity

ABSTRACT Personality traits can be employed to guide understanding of trajectories to health and longevity, but long-term longitudinal study and multifaceted assessment of healthy aging are crucial. Following up on the life span study initiated by Lewis Terman, we assessed 4 validated factors of personality in young adulthood in 1940, constructed a multifactor measure of participants' healthy aging in 1986, and collected death certificates through 2007 (to determine longevity) on a sample of 1,312 Terman participants (732 men). Neuroticism predicted worse physical health and subjective well-being in old age and, for women, higher mortality risk, but for men, neuroticism predicted decreased mortality risk. For both sexes, extraversion predicted old-age social competence, whereas conscientiousness predicted men's old-age productivity. Differential patterns of association between personality traits and healthy aging components are informative about individual personality characteristics and long-term health outcomes.     

Evolutionary psychology and developmental dynamics: comment on Lickliter and Honeycutt (2003)

Evolutionary psychology provides a cogent metatheory for psychological science. It has furnished compelling theories of major domains of human functioning, including mating, parenting, kinship, morality, cooperation, conflict, aggression, and aesthetics. It has produced hundreds of empirical discoveries missed entirely by prior psychologists. Developmental dynamics, properly conceived, can add to the theoretical foundation of evolutionary psychology. But it has not provided alternative theories capable of explaining the many detailed empirical discoveries made by evolutionary' psychologists. Nor has it generated a comparable bounty of new empirical discoveries. By critical scientific standards--theoretical cogency, predictive accuracy, interdisciplinary consistency, and empirical harvest--modern evolutionary psychology fares well compared with alternatives.     

Psychometric evaluation of the outcome based performance measures

The Outcome Based Performance Measures are widely used to evaluate and accredit organizations providing services to persons with disabilities. This study evaluated the interrater reliability, levels of difficulty for items, and factor groupings of this measure with 448 Nevadans with mental retardation. Results supported the measure's reliability and most of the items' levels of difficulty. Factor analysis yielded seven factors with item loadings that varied moderately from prior reports, tending to coincide with the original measure's logically-based groupings. Revisions to the measure are suggested.     

Classroom-based functional and adjunctive assessments: proactive approaches to intervention selection for adolescents with attention deficit hyperactivity disorder.

The present investigation evaluated the utility of classroom-based functional and adjunctive assessments of problem behaviors for 2 adolescents who met diagnostic criteria for attention deficit hyperactivity disorder (ADHD) and comorbid oppositional defiant disorder (ODD). For children with ADHD-ODD, environmental classroom variables, when systematically manipulated by teachers, were related to the occurrence and nonoccurrence of problem behaviors. Classroom interventions derived from information that was obtained during functional and adjunctive assessments and from subsequent analyses resulted in substantial reductions in problem behaviors. Teacher and student consumer satisfaction ratings indicated that the interventions were effective and feasible in the classroom setting.     

Impulsivity and speed-accuracy tradeoffs in information processing

Despite its theoretical importance for such areas of research as reflection-impulsivity (Kagan, 1966), there is little evidence to support the assumption that individual differences in the personality trait of impulsivity are associated with differences in the willingness to sacrifice accuracy for speed of information processing. The present studies explored this association further. In Experiment 1, high, medium, and low impulsives (identified by self-report) performed a visual-comparison task under conditions differing in the monetary payoff for speed relative to accuracy. High impulsives were consistently faster and less accurate than other subjects. However, an analysis based on Sternberg's (1969) additive-factor method indicated that high impulsives performed at least one stage of information processing as slowly and accurately as other subjects. In Experiment 2, it was found that high impulsives were actually more accurate than low impulsives when all subjects were required to process information extremely rapidly. Experiment 3 identified the response execution stage as one that high impulsives carry out just as slowly and accurately as other individuals. The data from these experiments pose problems for a simple speed-accuracy tradeoff model of impulsive cognitive functioning.     

THE EFFECTS OF INTERSPERSED MAINTENANCE TASKS ON ACADEMIC PERFORMANCE IN A SEVERE CHILDHOOD STROKE VICTIM

We examined the effects of task-sequencing variables on the academic performance of an 8-year-old severe stroke victim. Within a multiple baseline design, previously acquired (maintenance) task trials were systematically interspersed at designated points in treatment among new (acquisition) task trials. The results showed improvements in both academic responding and subjective ratings of motivation in each of four treated areas (spelling, reading, word-finding, and memory). Social validation data obtained from standardized school placement examinations suggested marked improvement in a variety of related areas of academic functioning. Results suggest that children suffering severe strokes may be capable of learning more than has previously been suspected, and that behavioral treatments may improve such children's functioning.     

A COMPARISON OF SIMULTANEOUS AND DELAYED REINFORCEMENT AS TREATMENTS FOR FOOD SELECTIVITY

This study compared the relative efficacy of providing simultaneous or delayed reinforcement on food acceptance during meals. The participant was a 7-year-old boy with pervasive developmental disorder and a history of food selectivity. Results indicated that both procedures were effective in increasing acceptance; however, the simultaneous reinforcement procedure produced more rapid behavior change and a higher overall percentage of food acceptance.     

Some properties of binormamin

Three properties of the binormamin criterion for analytic transformation in factor analysis are discussed. Particular reference is made to Carroll's oblimin class of criteria.The research reported in this note was supported in part by the Program in Applied Mathematics and Statistics. National Science Foundation, and by the National Institute of Education, Department of Health, Education, and Welfare.     

FUNCTIONAL ANALYSIS AND INTERVENTION FOR BREATH HOLDING

We conducted a functional analysis of breath-holding episodes in a 7-year-old girl with severe mental retardation and Cornelia-de-Lange syndrome. The results showed that breath holding served an operant function, primarily to gain access to attention. The intervention, consisting of extinction, scheduled attention, and use of a picture card communication system, resulted in decreased breath holding.     

IMPROVING THE PEER INTERACTIONS OF STUDENTS WITH EMOTIONAL AND BEHAVIORAL DISORDERS THROUGH SELF-EVALUATION PROCEDURES: A COMPONENT ANALYSIS AND GROUP APPLICATION

We conducted two experiments examining the effects of a self-evaluation package on the peer interactions of students described as emotionally or behaviorally disordered. Experiment 1 assessed the additive effects of various components of a self-evaluation package on the frequency of inappropriate and appropriate peer interactions. The components assessed were rewards alone, rewards plus discussion, and self-evaluation plus rewards. Results showed limited effectiveness when rewards alone and rewards plus discussion were implemented. However, substantial improvements in peer interactions were observed when the self-evaluation component was added. Experiment 2 examined the efficacy and feasibility of the procedures when implemented in a group setting. Students in three classrooms served as participants. Direct observation data collected for 8 of the participants showed the procedures to be effective in improving peer interactions when implemented in a group context.
