Affective personality differences in neural processing efficiency confirmed using fMRI

To test for a relation between individual differences in personality and neural-processing efficiency, we used functional magnetic resonance imaging (fMRI) to assess brain activity within regions associated with cognitive control during a demanding working memory task. Fifty-three participants completed both the self-report behavioral inhibition sensitivity (BIS) and behavioral approach sensitivity (BAS) personality scales and a standard measure of fluid intelligence (Raven’s Advanced Progressive Matrices). They were then scanned as they performed a three-back working memory task. A mixed blocked/ event-related fMRI design enabled us to identify both sustained and transient neural activity. Higher BAS was negatively related to event-related activity in the dorsal anterior cingulate, the lateral prefrontal cortex, and parietal areas in regions of interest identified in previous work. These relationships were not explained by differences in either behavioral performance or fluid intelligence, consistent with greater neural efficiency. The results reveal the high specificity of the relationships among personality, cognition, and brain activity. The data confirm that affective dimensions of personality are independent of intelligence, yet also suggest that they might be interrelated in subtle ways, because they modulate activity in overlapping brain regions that appear to be critical for task performance.     

Neurofibromatosis Type 1 in Genetic Counseling Practice: Recommendations of the National Society of Genetic Counselors

The objective of this document is to provide recommendations for the genetic counseling of patients and families undergoing evaluation for neurofibromatosis type 1 (NF1) or who have received a diagnosis of NF1. These recommendations are the opinions of a multi-center working group of genetic counselors with expertise in the care of individuals with NF1. These recommendations are based on the committee’s clinical experiences, a review of pertinent English language medical articles, and reports of expert committees. These recommendations are not intended to dictate an exclusive course of management, nor does the use of such recommendations guarantee a particular outcome. These recommendations do not displace a health care provider’s professional judgment based on the clinical circumstances of an individual patient. Both Heather B. Radtke and Courtney D. Sebold contributed equally to this document.     

The dynamics of empirically derived factors in the therapeutic relationship

The therapeutic relationship is the source of major concepts in psychoanalytic clinical theory. Such concepts as resistance, transference, countertransference, and the alliance are fundamental, even though there may be shifts in meaning between theoretical schools and clinical contexts. In the clinical psychoanalytic literature, disagreement exists over the nature of the alliance and its essential components. Empirical studies using reliable patient, therapist, and observer scales to assess the alliance demonstrate a correlation with psychotherapeutic gains. In the study reported here, thirteen patients were followed for 6 to 33 months of psychodynamic psychotherapy, during which time their views of the therapeutic relationship were assessed, and several experiential measures taken, all on a weekly basis. Statistical analyses reveal that the therapeutic relationship, as reflected in the patients' weekly responses to the St. Louis Therapeutic Relationship Rating Scale, has four distinct components: therapeutic alliance, resistance, transference love, and negative transference. On a week-by-week basis, the therapeutic alliance was the strongest predictor of improvement in patient-reported general adjustment, as reflected in such areas as self-esteem, positive affect, social relations, work productivity, satisfaction, and optimism. Time plots of the variables show the typical time course for the components of the therapeutic relationship, as well as for improvement on the experiential variables. Results indicate that the therapeutic alliance, transference, and resistance are central components of the psychotherapeutic relationship, which in turn predict the ongoing life experience of the patient.     

EVALUATIONS OF SEXY WOMEN IN LOW- AND HIGH-STATUS JOBS

We hypothesized that women who dress in a sexy versus business-like manner evoke negative emotions and perceptions of lesser competence if employed in high- (but not low-) status jobs. Male and female undergraduates evaluated a videotaped female target whose physical attractiveness was held constant, but who was (a) dressed in sexy or business-like attire and (b) allegedly either a manager or a receptionist. Participants exhibited more negative affect toward the sexily attired manager and rated her as less competent than the neutrally attired manager. This effect was fully mediated by emotional reactions. In contrast, the appearance manipulation had no effect on emotions toward or competence ratings of the receptionist. These findings suggest that a sexy self-presentation harms women in high-, but not low-, status jobs.     

Scarcity,engagement, and value

Scarcity has been found to intensify value, positive or negative, rather than simply enhancing it. Some researchers have proposed that scarcity affects value by increasing how much attention is paid to a stimulus. We conceptualized sustained attention as stronger engagement and operationalized a situation of scarcity by telling participants who were choosing between two objects that the object that was chosen would then be replaced (Replenish) or not replaced (Scarce). To distinguish sustained attention-stronger engagement in a situation of scarcity from grabbing attention (salience from distinctiveness), the choice was between one option with a single instance (solitary-high salience) and a second option with several duplicates (abundant-low salience). We predicted that stronger engagement from a situation of scarcity would, first, intensify the value of the chosen item regardless of whether it was solitary or abundant, with positive items becoming more positive and negative items becoming more negative, and second, the stronger engagement from the situation of scarcity would transfer intensification to another separate object in the same setting. The results of Studies 1 and 2 supported both of these predictions. Study 3 tested a boundary condition for these scarcity–engagement effects in terms of how real participants experienced the choice items to be, where ‘realness’ is another source of engagement strength. As expected, the scarcity–engagement effect on intensifying value was replicated for participants who experienced the activity as real but was eliminated for those who did not.
