Integrating the dynamics of personality and close relationship processes: methodological and data analytic implications

A common theme that has emerged from classic and contemporary theoretical work in both the fields of personality and relationship science is a focus on process. Current process-focused theories bearing on personality invoke a view of the individual in ongoing action and interaction with the environment, reflecting a flow of experience rather than a static depiction. To understand the processes by which personality interacts with the social environment (particularly dyads), investigations must capture individuals interacting in multiple interpersonal situations, which likely necessitates complex study designs and corresponding data analytic strategies. Using an illustrative simulated data set, we focus on diary methods and corresponding individual and dyadic multilevel models to capture person-situation interaction within the context of processes in daily close relationship life. Finally, we consider future directions that conceptualize personality and close relationship processes from a dynamical systems theoretical and methodological perspective.     

Serotonin transporter polymorphism interacts with childhood adversity to predict aspects of impulsivity

The serotonin transporter polymorphism has been linked--often in interaction with environmental adversity--to a variety of outcomes, including affective disorders. This polymorphism is widely viewed as relating to anxiety traits. A different view is that it relates instead to impulsivity (vs. control) in reacting to emotions. In a test of the latter view, 303 students were genotyped on this polymorphism and completed self-reports bearing on impulsive reactions to emotions (including both negative and positive emotions in separate measures), impulsive tendencies that do not stem from emotions, and childhood adversity. The impulsivity measures reflected three latent variables: pervasive influence of feelings, feelings (including positive feelings) triggering action, and failure to carry through on intentions (with no mention of emotion). Interactions between genotype and adversity emerged for both emotion-related aspects of impulsivity. Theoretical implications of the findings are discussed.     

Effects of viewing ordered pictorial reminders on long-term memory in the first year of life

Previous research has shown that reminders can be effective for extending and enhancing a variety of kinds of memory in infants. We investigated the effects of viewing pictorial representations of actions that were included in imitation events used to measure long-term memory in young infants. Infants who saw the pictures of actions displayed in the order in which they comprised events showed evidence of memory for the events. Infants who saw the actions presented randomly did not. These results suggest that pictures presented during the consolidation and storage phase of memory formation can be effective reminders of events for young infants.     

Optimism, coping, and health: assessment and implications of generalized outcome expectancies

This article describes a scale measuring dispositional optimism, defined in terms of generalized outcome expectancies. Two preliminary studies assessed the scale's psychometric properties and its relationships with several other instruments. The scale was then used in a longitudinal study of symptom reporting among a group of undergraduates. Specifically, respondents were asked to complete three questionnaires 4 weeks before the end of a semester. Included in the questionnaire battery was the measure of optimism, a measure of private self-consciousness, and a 39-item physical symptom checklist. Subjects completed the same set of questionnaires again on the last day of class. Consistent with predictions, subjects who initially reported being highly optimistic were subsequently less likely to report being bothered by symptoms (even after correcting for initial symptom-report levels) than were subjects who initially reported being less optimistic. This effect tended to be stronger among persons high in private self-consciousness than among those lower in private self-consciousness. Discussion centers on other health related applications of the optimism scale, and the relationships between our theoretical orientation and several related theories.     

Physical aggression as a function of objective self-awareness and attitudes toward punishment

Based on a theory of self-awareness, it was hypothesized that subjects would use their attitudes to determine their behaviors when (a) that attitude was salient and (b) their attention was directed toward themselves. Subjects, who on questionnaires had indicated that they opposed or condoned the use of punishment, were given the opportunity to shock a male confederate in two (bogus) learning experiments. Each subject was instructed to use his own attitude in choosing shocks to punish incorrect responses. Self-awareness was increased among half the subjects by the presence of a mirror. In each experiment a Punitiveness by self-awareness interaction resulted: High Punitive-Mirror subjects shocked higher than Low Punitive-Mirror subjects, but their respective No Mirror controls did not differ from each other.     

Facilitation of physical aggression through objective self-awareness

Based on a theory of self-awareness it was hypothesized that induced attention to the self would facilitate aggression if the salient standard of behavior was one in which high aggression was positively valued. Female subjects were given an opportunity to shock a male confederate of the experimenter in a presumed learning experiment. Self-awareness was induced in half the subjects by the presence of a mirror. The Mirror group delivered significantly higher shocks to the confederate than did the No-Mirror control group.     

Outcome expectancy,locus of attribution for expectancy,and self-directed attention as determinants of evaluations and performance

Are internal versus external attributions of responsibility for prior outcomes important determinants of subsequent performances? or is their effect limited to influencing the affective and evaluative experiences that are associated with the task outcomes? Recent theoretical statements appear to differ on this issue. The present study examined the question, while at the same time testing the influence of self-directed attention on the process under investigation. Subjects attempted a series of mazes in collaboration with an ostensible cosubject (actually a confederate). The pair experienced either three consecutive sucesses or three consecutive failures. Subjects were led to perceive the responsibility for these outcomes as residing primarily with themselves or primarily with their partner. Self-focus was manipulated (by a mirror) prior to attempting a fourth maze and completing a set of rating scales. Success-condition subjects performed better on the fourth maze in the mirror's presence than in its absence, whereas failure-condition subjects tended to perform more poorly in the mirror's presence than in its absence. The manipulation of internal versus external attributions did not influence behavior, but did influence subjects' affective and evaluative reactions to themselves and their partner. Discussion centers on the relationship between these findings and other recent findings in the areas of attribution and achievement-related behavior.     

Generalization, Adverse Events, and Development of Depressive Symptoms

Many diathesis-stress models have been proposed in which cognitive processes of various types are presumed to represent vulnerabilities to development of depressive symptoms. This study tested three potential vulnerabilities as prospective predictors of such symptoms: the holding of especially high standards, the tendency to be self-critical after failure, and the tendency to generalize from a single failure to the broader sense of self-worth. At the start of a semester, college students completed a measure of these cognitive tendencies and a measure of depressive symptoms. Six weeks later they completed the same measure of depressive symptoms and a brief measure of intervening life events. Hierarchical regression analysis yielded evidence that Generalization interacted with adverse events to predict subsequent depressive symptoms. Self-Criticism also tended to predict later symptoms, but only if the symptoms were present initially. High Standards had no adverse effect.     

Effects of amount of attention allocated to the location of visual stimulus pairs on perception of simultaneity

This study examined whether a change in the amount of attention equally allocated to two locations affects judgments of the simultaneity or successiveness of stimuli presented at those locations. Observers were cued to expect two brief flashes either to the left and right of fixation or above and below fixation. Stimulus onset asynchrony was randomly varied. On a small proportion of trials, the stimuli appeared at the unexpected locations. Observers were more likely to report the stimuli as simultaneous when they appeared in the unexpected locations. A model proposed to account for the data assumes that a brief stimulus event is represented by a probability distribution reflecting the uncertainty in determining the time of the event’s occurrence, and two events are judged to be simultaneous if they are perceived to fall within some critical temporal interval, c, which is a function of the amount of attention allocated to the task.     

Self-focused attention and the placebo effect: Fooling some of the people some of the time

An experiment tested the hypothesis that mirror-induced self-awareness would minimize a “placebo” effect. Some subjects were led to believe that a drug that they were about to ingest would produce arousal symptoms as a side effect. Self-aware subjects in this condition subsequently reported experiencing less arousal from the placebo, and fewer of the side effects ascribed to it, than did less self-aware subjects. Discussion centered on the implications of these findings for placebo research and implications for two common alternative interpretations of self-awareness effects.
