Individual Differences Associated with Emotional and Behavioral Responses to Ambiguous Social Situations in which Rejection Might be Inferred

This study sought to examine the extent to which undergraduates' experiences with and attitudes relevant to rejection may be associated with their emotional and behavioral responses to ambiguous social situations in which rejection might be inferred. Undergraduate students completed questionnaires that assessed their experiences with and attitudes relevant to being rejected. Next, each participant read six hypothetical scenarios that described various situations that could be interpreted as interpersonal rejection. Following each scenario, participants completed questionnaires that assessed their emotional and behavioral responses to the hypothetical situation. Analyses revealed that the participants' experiences with rejection (and, to a lesser extent, their rejection-relevant attitudes) were associated with a negative emotional response and some negative behavioral responses. In sum, when another individual's interpersonal behavior has an uncertain intent, undergraduates' prior experiences with rejection may be especially important in determining the extent to which they feel and act as if they have been rejected.     

A Cross-Cultural Investigation of Relational and Social Aggression in Female College Students from Puerto Rico and the United States

Researchers compared scores on a self-report measure of relational and social aggression using 2 groups, European American female university students (M = 20.23 years, SD = 3.88) from the mid-Atlantic region of the United States and Hispanic females from Puerto Rico (M = 19.34 years, SD = 1.26). Results indicate that cultural differences were evident in the use of relational and social aggression. The exclusively Hispanic Puerto Rican sample reported being more socially aggressive than the European American, mid-Atlantic sample. In contrast, the European American sample identified as being more relationally aggressive in their relationships than the Hispanic Puerto Rican sample. This distinction allows us to consider potential cultural differences in interpersonal relations in college-age females.     

Interactive Effects of Team and Task Shared Mental Models as Related to Air Traffic Controllers' Collective Efficacy and Effectiveness

We assessed the influence of task and team shared mental models (SMMs) on team effectiveness, as mediated by collective efficacy. Using a sample of 422 air traffic controllers representing 43 Navy teams from land-based towers, task SMMs exhibited a significant linear relationship with team effectiveness, whereas team SMMs did not. Moreover, the interaction of team and task SMMs was positively related to team effectiveness. Collective efficacy was found to mediate the relationship between task SMMs (but not team SMMs or their interaction) and team effectiveness. Results are discussed in terms of the complex nature of SMMs and team outcomes.     

Anxiety sensitivity and distress tolerance typologies and relations to posttraumatic stress disorder: A cluster analytic approach

A growing literature suggests a relationship between a high anxiety sensitivity (AS; the fear of anxiety and its related consequences)/low distress tolerance (DT; the capacity tolerate internal negative states) profile and posttraumatic stress disorder (PTSD) symptoms. However, specific profiles have not been identified or examined specifically in Veteran samples. Thus, the aims of the present study were to establish empirically derived profiles created from response patterns on the Anxiety Sensitivity Index and Distress Tolerance Scale and to examine associations with PTSD symptom clusters among a sample of combat-exposed Veterans (N = 250). A cluster analytic approach was used to identify AS/DT profiles, and a series of multivariate analyses of variance with post hoc analyses was conducted to examine the relationship between each AS/DT profile and each PTSD symptom cluster. Results indicated a 3-cluster solution including a high AS/low DT “at risk” profile, a low AS/high DT “resilient” profile, and an average AS/DT “intermediate” profile. The at-risk profile was associated with significantly greater symptoms in each PTSD cluster (i.e., hyperarousal, avoidance, re-experiencing) when compared to the other two profiles. The at-risk profile was also associated with greater depressive symptoms and lower self-reported resilience. These findings extend the previous literature by identifying a high AS/low DT “at risk” profile and its associations with PTSD symptoms, underscoring the potential utility in targeting these affect-regulation constructs for clinical intervention.     

Item method directed forgetting diminishes false memory

Directed forgetting may reduce the ORM false memory illusion by interfering with meaning processing. Participants were presented with a list composed of six 10-word semantically associated sub-lists, and they were either (a) asked to remember a ll list it ems or (b) asked to remember all associates from sub-lists and to forget all associates from other sub-lists. All participants were requested to recall and recognise list items. Although directed forgetting effects have been previously reported only for true responses in the ORM paradigm with the list method, we also found directed forgetting for false responses with the item method. Such forgetting instructions reduced both verbatim and meaning processing, decreasing both the intrusion and the false alarm rate. These results are consistent with two-process explanations of DRM false memories, such as fuzzy-trace theory, and add to our understanding of false memory editing.     

A dyadic examination of the role of relationship characteristics and age on relationship satisfaction in a formal mentoring programme

Research was conducted to test ideas derived from Wanberg, Welsh, and Hezlett's (2003) dynamic process model of formal mentoring to examine (1) the role of respect and communication in mentorship relationship satisfaction, and (2) whether the age of the mentor or the protégé would impact those relationship qualities. The sample was comprised of 117 matched mentor–protégé pairs from an organization's formal mentoring programme. We received survey data from both partners and used the Actor–Partner Interdependence Model to examine individual and dyadic effects. Data suggest that protégés' respect for the mentor and communication quality, as perceived by both partners, were independent predictors of mentorship relationship satisfaction. Protégés rated their relationships as more satisfying than did their mentors. Hypotheses regarding age differences in relational qualities were not supported. We suggest that researchers continue to examine formal relationships at the dyadic level, and that practitioners designing formal mentoring programmes consider interventions to enhance communication and respect.     

What does rapid automatized naming measure? A new RAN task compared to naming and lexical decision

The present research investigated the relationship between Rapid Automatized Naming (RAN) performance, letter-string reading measures of sight vocabulary (SV) and phonetic decoding (PD), and lexical decision. Criterion-based naming rates were obtained from three types of RAN tasks: digits, letters, and letter sounds. Latency measures were obtained from the naming of regular words, exception words, nonwords and pseudohomophones; as well as button press and verbal lexical decision tasks. Regression analyses supported the hypotheses that RAN-Letters latency reflects SV processing in that its variance is uniquely accounted for by exception word naming latency and button press lexical decision latency, and that RAN-Letter Sounds latency best reflects PD processing in that its variance is uniquely accounted for by pseudohomophone and nonword naming latency. Findings are discussed in light of what the RAN tasks are measuring, implications involving visual word recognition models of reading, and the utility of the new RAN-Letter Sounds task with respect to diagnostic and remediation applications.     

Self-verification and contextualized self-views

Whereas most self-verification research has focused on people's desire to verify their global self-conceptions, the present studies examined self-verification with regard to contextualized selfviews-views of the self in particular situations and relationships. It was hypothesized that individuals whose core self-conceptions include contextualized self-views should seek to verify these self-views. In Study 1, the more individuals defined the self in dialectical terms, the more their judgments were biased in favor of verifying over nonverifying feedback about a negative, situation-specific self-view. In Study 2, consistent with research on gender differences in the importance of relationships to the self-concept, women but not men showed a similar bias toward feedback about a negative, relationship-specific self-view, a pattern not seen for global self-views. Together, the results support the notion that self-verification occurs for core self-conceptions, whatever form(s) they may take. Individual differences in self-verification and the nature of selfhood and authenticity are discussed.     

The role of neuropeptide Y in the amygdala on corticotropin-releasing factor receptor-mediated behavioral stress responses in the rat

Neuropeptide Y (NPY) is one of the most abundant peptides in the brain and has been shown to be a critical regulator of emotionality, most notably for its effect in decreasing anxiety-like behaviors. The stress response in both humans and animals has been shown to involve a cascade of biological events initiated by corticotropin releasing factor (CRF), another centrally acting peptide. Interestingly, NPY and CRF are present in similar brain regions mediating stress responses and may act in an opposing fashion. The basolateral nucleus of the amygdala (BLA) is a distinct division of the amygdala and contains CRF receptors and the highest concentration of NPY neurons. The current study investigates the behavioral effects in rodents when NPY is injected directly into the BLA prior to the pharmacological stressor, urocortin I (Ucn; a CRF receptor agonist) or the emotional stressor, restraint. The animals that underwent restraint were evaluated in the social interaction (SI) test, while those injected with Ucn into the BLA were assessed in the two floor choice test, a modified version of the conditioned-place avoidance paradigm. The results showed that injections of NPY into the BLA prior to Ucn significantly blocked the development of the avoidance behavior in the two floor choice test and the decrease in SI time that is usually seen following restraint stress. These results provide further support that an interaction between NPY and CRF within the BLA may be critical for maintaining a normal homeostatic emotional state.     

Bimodal score distributions and the Myers-Briggs Type Indicator: fact or artifact?

We examined Myers-Briggs Type Indicator (MBTI) score distributions computed using item response theory (IRT) to assess the generalizability of earlier bimodality reports that have been cited in support of the "type" versus "trait" view of personality. Using the BILOG IRT program to score a sample of approximately 12,000 individuals who participated in leadership development programs, theta score distributions for the 4 dimensions of the MBTI computed using 10 (the BILOG default) versus 50 quadrature points were compared. Results indicated that past reports of bimodality were artifacts caused by BILOG's default use of a small number of quadrature points; when larger numbers of points were used, score distributions became strongly center-weighted. Although our findings are not supportive of the "type"-based hypothesis, the extremely high correlations between theta scores (rs > .996) suggest that no practical differences would be expected as a function of the number-of-quadrature-points decision.
