The role of implicit motivation in hot and cold goal pursuit: Effects on goal progress, goal rumination, and emotional well-being

Two cross-sectional studies examined the role of implicit motivational needs in the association between personal goal pursuits and depressive symptoms and affect. Replicating and extending on findings reported by Brunstein et al. [Brunstein, J. C., Schultheiss, O. C., & Grässmann, R. (1998). Personal goals and emotional well-being: The moderating role of motive dispositions. Journal of Personality and Social Psychology, 75(2), 494–508], both studies provided evidence that goal progress significantly accounted for variations in depressive symptoms and happiness only in individuals with high levels of implicit motivation, but not in individuals low in implicit motivation. Moreover, in the absence of a strong sense of goal commitment, high levels of implicit motivation were associated with high goal progress in both studies and low levels of goal rumination in Study 2. These findings are interpreted within a dual-systems framework of motivation that distinguishes an implicit, intuitive, and hedonically driven from an explicit, effortful-analytical, and non-hedonic mode of goal pursuit.     

Right hemisphere metaphor processing? Characterizing the lateralization of semantic processes

Previous laterality studies have implicated the right hemisphere in the processing of metaphors, however it is not clear if this result is due to metaphoricity per se or another aspect of semantic processing. Three divided visual field experiments varied metaphorical and literal sentence familiarity. We found a right hemisphere advantage for unfamiliar sentences containing distant semantic relationships, and a left hemisphere advantage for familiar sentences containing close semantic relationships, regardless of whether sentences were metaphorical or literal. This pattern of results is consistent with theories postulating predominantly left hemisphere processing of close semantic relationships and predominantly right hemisphere processing of distant semantic relationships.     

Social anxiety and interpretation biases for facial displays of emotion: emotion detection and ratings of social cost

The current study assessed the processing of facial displays of emotion (Happy, Disgust, and Neutral) of varying emotional intensities in participants with high vs. low social anxiety. Use of facial expressions of varying intensities allowed for strong external validity and a fine-grained analysis of interpretation biases. Sensitivity to perceiving negative evaluation in faces (i.e., emotion detection) was assessed at both long (unlimited) and brief (60 ms) stimulus durations. In addition, ratings of perceived social cost were made indicating what participants judged it would be like to have a social interaction with a person exhibiting the stimulus emotion. Results suggest that high social anxiety participants did not demonstrate biases in their sensitivity to perceiving negative evaluation (i.e. disgust) in facial expressions. However, high social anxiety participants did estimate the perceived cost of interacting with someone showing disgust to be significantly greater than low social anxiety participants, regardless of the intensity of the disgust expression. These results are consistent with a specific type of interpretation bias in which participants with social anxiety have elevated ratings of the social cost of interacting with individuals displaying negative evaluation.     

Posttraumatic stress disorder symptoms, physiological reactivity, alcohol problems, and aggression among military veterans

This study examined the association between posttraumatic stress disorder (PTSD) symptomatology and aggressive behavior among a sample of male Vietnam veterans (N = 1,328). Results indicated that the hyperarousal PTSD symptom cluster evidenced the strongest positive association with aggression at the bivariate level when compared with the other PTSD symptom clusters. When the PTSD symptom clusters were examined together as predictors, hyperarousal symptoms evidenced a significant positive relationship with aggression, and avoidance/numbing symptoms were negatively associated with aggression. Examination of potential mediators indicated that hyperarousal symptoms were directly associated with aggression and indirectly related to aggression via alcohol problems. Reexperiencing symptoms were associated with aggression only indirectly and through their positive association with physiological reactivity and negative association with alcohol problems. Study results highlight the complexity of the relationship between PTSD symptoms and aggression, and suggest possible mechanisms explaining this association.     

Too much to count on: impaired very small numbers in corticobasal degeneration

Patients with corticobasal degeneration (CBD) have calculation impairments. This study examined whether impaired number knowledge depends on verbal mediation. We focused particularly on knowledge of very small numbers, where there is a precise relationship between a cardinality and its number concept, but little hypothesized role for verbal mediation. We evaluated accuracy and reaction time (RT) for matching dot arrays and Arabic numerals involving smaller (2-4) and larger (5-9) cardinalities in non-aphasic patients with CBD (n=16), frontotemporal dementia (FTD; n=23), and healthy controls (n=15). CBD were less accurate and slowed at judging smaller Arabic numeral-dot array stimuli compared to FTD patients and controls. Moreover, only CBD showed longer RTs judging successively larger number-dot array pairs among the smaller cardinalities. Difficulty judging very small numbers is impaired in CBD, suggesting degraded representation of precise number knowledge that does not depend on language functioning.     

Risk‐taking and the adolescent brain: who is at risk?

Relative to other ages, adolescence is described as a period of increased impulsive and risk-taking behavior that can lead to fatal outcomes (suicide, substance abuse, HIV, accidents, etc.). This study was designed to examine neural correlates of risk-taking behavior in adolescents, relative to children and adults, in order to predict who may be at greatest risk. Activity in reward-related neural circuitry in anticipation of a large monetary reward was measured with functional magnetic resonance imaging, and anonymous self-report ratings of risky behavior, anticipation of risk and impulsivity were acquired in individuals between the ages of 7 and 29 years. There was a positive association between accumbens activity and the likelihood of engaging in risky behavior across development. This activity also varied as a function of individuals' ratings of anticipated positive or negative consequences of such behavior. Impulsivity ratings were not associated with accumbens activity, but rather with age. These findings suggest that during adolescence, some individuals may be especially prone to engage in risky behaviors due to developmental changes in concert with variability in a given individual's predisposition to engage in risky behavior, rather than to simple changes in impulsivity.     

Court populations in need of services: defining the court's role

Court populations frequently include individuals in need of educational, employment, health, housing, mental health, social, and other types of services that are not commonly provided by the judicial system. Courts vary in the ways they address the service needs of these individuals based on a variety of factors specific to their respective jurisdiction. Following a discussion of some of these approaches, the article offers a framework, based on Bronfenbrenner's human development paradigm and its focus on environmental contexts, to help courts more systematically and comprehensively define their role in service issues within the legal and service parameters of their own jurisdiction. © 1998 John Wiley & Sons, Ltd.     

Parental Influence on Children with Attention-Deficit/Hyperactivity Disorder: II. Results of a Pilot Intervention Training Parents as Friendship Coaches for Children

We report findings from a pilot intervention that trained parents to be “friendship coaches” for their children with Attention-Deficit/Hyperactivity Disorder (ADHD). Parents of 62 children with ADHD (ages 6–10; 68% male) were randomly assigned to receive the parental friendship coaching (PFC) intervention, or to be in a no-treatment control group. Families of 62 children without ADHD were included as normative comparisons. PFC was administered in eight, 90-minute sessions to parents; there was no child treatment component. Parents were taught to arrange a social context in which their children were optimally likely to develop good peer relationships. Receipt of PFC predicted improvements in children’s social skills and friendship quality on playdates as reported by parents, and peer acceptance and rejection as reported by teachers unaware of treatment status. PFC also predicted increases in observed parental facilitation and corrective feedback, and reductions in criticism during the child’s peer interaction, which mediated the improvements in children’s peer relationships. However, no effects for PFC were found on the number of playdates hosted or on teacher report of child social skills. Findings lend initial support to a treatment model that targets parental behaviors to address children’s peer problems.     

Moral credentialing by association: the importance of choice and relationship closeness

People express more prejudice if they have established their "moral credentials." Five studies explored the acquisition of moral credentials through associations with racial minorities, particularly close relationships that are personally chosen. Participants choosing to write about a positive experience with a Black person (Study 1) or Hispanic person (Study 2) subsequently expressed more preference for Whites and tolerance of prejudice than did other participants. In Study 3, the credentialing effect of choice was diminished when participants were given an incentive for that choice. Participants in Study 4 who wrote about a Black friend were more credentialed than those who wrote about a Black acquaintance, regardless of whether the experience was positive or negative. Study 5 suggested that participants strategically referred to close associations with minorities when warned of a future situation in which they might appear prejudiced.
