Personality disorders and personality dimensions in anorexia nervosa

Information on the relationship between anorexia nervosa (AN) and personality disorders (PDs) and dimensions of temperament and character (measured by the Temperament and Character Inventory [TCI; Cloninger, Przybeck Svrakic, & Wetzel, 1994]) is limited. This study examines the predictive validity of the TCI for PD diagnoses assessed by the International Personality Disorder Examination-ICD-10 (IPDE-ICD-10; Loranger, Janca, & Sartorius, 1997) interviews of 46 women with DSM-IV-defined AN. Patients with a PD reported higher levels of harm-avoidance and lower levels of self-directedness than those without a PD. Scores on the TCI were predictive of the number of PD features present, particularly for those PDs in the anankastic, anxious, and dependent groups accounting for 40% to 51% of the variance. Cluster analysis based on scores on the TCI identified a subgroup of patients characterized by low levels of novelty seeking, self-directedness, and cooperativeness and high levels of harm avoidance. This cluster included the majority of those with avoidant, anxious, or dependent PDs. Assessment of particular personality dimensions was able to predict PDs in an anorexic sample. Since normal personality dimensions have greater validity than the categorical PDs, a consideration of normal temperament and character may assist in clinical decisionmaking and considerations concerning treatment.     

Birth order effects in dominance: failure to support Sulloway's view

Contrary to Sulloway's 1996 assertion that firstborns should score higher than laterborns on measures of dominance, the dominance scores for 76 firstborn undergraduate students (50 women, 26 men) did not differ significantly from the scores of 75 laterborn students (48 women, 27 men) on the 16PF dimension of Dominance vs Submissiveness (Factor E). Further research into possible differences in performance strategies between laterborns and firstborns in childhood vs adulthood is necessary to evaluate Sulloway's theory of ordinal position definitively.     

Differential risks of covarying and pure components in mother and teacher reports of externalizing and internalizing behavior across ages 5 to 14

In a sample of 585 children assessed in kindergarten through 8th grade, we fit a confirmatory factor model to both mother- and teacher-reported symptoms on the Achenbach checklists (CBCL, TRF) and determined that a covariation factor of externalizing and internalizing behaviors existed, in addition to the pure-form factors of externalizing and internalizing for each reporter. In 3 structural equation models, between 8 and 67% of the variance in these 6 latent factors was accounted for by a set of antecedent child, sociocultural, parenting, and peer risk variables. Each of the 6 latent factors, taken 2 at a time, was predicted by a unique set of risk variables; however, there were some patterns that held for both mother- and teacher-report symptom factors: Child temperamental unadaptability and female gender were predictors of higher internalizing symptoms; child temperamental resistance to control, parental harsh punishment, male gender, low SES, and peer rejection were related to higher externalizing symptoms whereas child temperamental unadaptability was related to lower externalizing symptoms; and peer rejection and family stress were also related to the covarying, externalizing-plus-internalizing component of both mother and teacher reports.     

Goal-specific influences on the representation of spatial perspective

In two experiments, subjects learned an unfamiliar campus environment, either by studying a map or by navigating. During acquisition, the subjects had one of two spatial goals: to learn the layout of the building (survey goal) or to learn the fastest routes between locations (route goal). Spatial memory was tested with several tasks, some assessing survey perspective processing and some assessing route perspective processing. Results indicate multiple influences on the representation of spatial perspective. Learning condition influenced performance. Individuals studying maps gave more accurate responses to some survey perspective tasks, whereas individuals navigating gave more accurate responses to some route perspective tasks. Spatial goals also influenced performance. Having a route goal enhanced performance on route perspective tasks; having a survey goal enhanced performance on survey perspective tasks. These findings are discussed in the context of research indicating flexibility when processing spatial perspective. Individuals can use spatial information from different perspectives, often doing so in a goal-directed manner.     

The Supervisory Working Alliance,Trainee Self-Efficacy,and Satisfaction

Theoretically, when the supervisory working alliance is strong, the trainee and supervisor share a strong emotional bond and agree on the goals and tasks of supervision. Tested was Bordin's (1983) proposition that changes in counselor trainees' perceptions of the supervisory alliance over the course of supervision would predict supervisory outcomes. A national sample of beginning practicum- to intern-level trainees were assessed at the beginning and end of an academic semester. Contrary to predictions, changes in the alliance were not predictive of changes in trainees' self-efficacy. However, improvements in the emotional bond between the trainees and supervisors were associated with greater satisfaction.     

Gender,Race, and Performance Expectations of College Students

Women often have low performance expectations for themselves but expect other women to succeed. We found minority students think not only that they will do worse than other minority group members, but also that their group will do poorly. Low individual and group success expectations make the results for minorities doubly troubling.     

Advantages of heterogeneous therapy groups in the psychotherapy of the traumatically abused: treating the problem as well as the person.

The authors combine a social-constructionist perspective with a psychodynamic one in discussing the problem of trauma and its treatment. They argue that effective treatment of traumatic physical, sexual, and psychological abuse must do more than alleviate the pain of the sufferer. Factors that cause and perpetuate abuse must be addressed by the abused person in conjunction with other nontraumatized persons who may have been abusive or passive in the face of abuse. An argument is made for heterogeneous therapy groups as a context for this to occur.     

Medical Students' Perceptions of and Willingness to Treat Patients Who Are HIV Infected1

The purpose of this study is to examine the independent and joint influences of a patient's mode of acquisition of illness (blood transfusion vs. multiple sexual partners), attributions of responsibility (self-blame vs. chance blame), and sexual orientation (homosexual vs. heterosexual) on female and male medical students' attitudes toward and willingness to treat a patient who is HIV infected. One hundred nineteen 1st through internship-year medical students were randomly assigned to read and respond to case vignettes. Greater consistency between attribution of blame and mode of acquisition was related to more positive perceptions. Furthermore, the patient's sexual orientation influenced the providers' willingness to offer treatment, particularly for male medical students. Implications concerning health practices and medical education are considered.     

Storage of verbal associations is sufficient to activate the left medial temporal lobe

Neuroimaging studies have shown that memory encoding activates the medial temporal lobe (MTL). Many believe that these activations are related to novelty but it remains unproven which is critical - novelty detection or the rich associative encoding it triggers. We examined MTL activation during verbal associative encoding using functional magnetic resonance imaging. First, associative encoding activated left posterior MTL more than single word encoding even though novelty detection was matched, indicating not only that associative encoding activates the MTL particularly strongly, but also that activation does not require novelty detection. Moreover, it remains to be convincingly shown that novelty detection alone does produce such activation. Second, repetitive associative encoding produced less MTL activation than initial associative encoding, indicating that priming of associative information reduces MTL activation. Third, re-encoding familiar associations in a well-established way had a minimal effect on both memory and MTL activation, indicating that MTL activation reflects storage of associations, not merely their initial representation.
