Casting Off the Perishable

In this narrative, the author, a physician, recounts her mother's courageous, controversial final decisions and the interior struggles that subsequently confront the daughter-doctor. Family dynamics are outlined in this journalistic format, and tensions including the daughter's commitment to defending her mother's choice and the daughter's own grief, are presented.     

Rejection sensitivity and disruption of attention by social threat cues

Two studies tested the hypothesis that Rejection Sensitivity (RS) increases vulnerability to disruption of attention by social threat cues, as would be consistent with prior evidence that it motivates individuals to prioritize detecting and managing potential rejection at a cost to other personal and interpersonal goals. In Study 1, RS predicted disruption of ongoing goal-directed attention by social threat but not negative words in an Emotional Stroop task. In Study 2, RS predicted attentional avoidance of threatening but not pleasant faces in a Visual Probe task. Threat-avoidant attention was also associated with features of borderline personality disorder. This research extends understanding of processes by which RS contributes to a self-perpetuating cycle of interpersonal problems and distress.     

Modeling the Bullying Prevention Program Preferences of Educators: A Discrete Choice Conjoint Experiment

We used discrete choice conjoint analysis to model the bullying prevention program preferences of educators. Using themes from computerized decision support lab focus groups (n = 45 educators), we composed 20 three-level bullying prevention program design attributes. Each of 1,176 educators completed 25 choice tasks presenting experimentally varied combinations of the study’s attribute levels. Latent class analysis yielded three segments with different preferences. Decision Sensitive educators (31%) preferred that individual schools select bullying prevention programs. In contrast, Support Sensitive educators (51%) preferred that local school boards chose bullying prevention programs. This segment preferred more logistical and social support at every stage of the adoption, training, implementation, and long term maintenance processes. Cost Sensitive educators (16%) showed a stronger preference for programs minimizing costs, training, and implementation time demands. They felt prevention programs were less effective and that the time and space in the curriculum for bullying prevention was less adequate. They were less likely to believe that bullying prevention was their responsibility and more likely to agree that prevention was the responsibility of parents. All segments preferred programs supported by the anecdotal reports of colleagues from other schools rather than those based on scientific evidence. To ensure that the bullying prevention options available reflect the complex combination of attributes influencing real world adoption decisions, program developers need to accommodate the differing views of the Decision, Support, and Cost Sensitive segments while maximizing the support of parents and students.     

Chronic glucocorticoid hypersecretion in Cushing’s syndrome exacerbates cognitive aging

Cumulative exposure to glucocorticoid hormones (GC) over the lifespan has been associated with cognitive impairment and may contribute to physical and cognitive degeneration in aging. The objective of the present study was to examine whether the pattern of cognitive deficits in patients with Cushing’s syndrome (CS), a disorder characterized by chronic exposure to elevated levels of glucocorticoids (GC), is similar to that observed in older individuals. Ten subjects with CS were compared to sex-, age-, and education-matched healthy controls and older subjects (age of CS subjects + 15 yr). All participants were administered tests to assess attention, visuospatial processing, learning and memory, reasoning, concept formation and verbal fluency. MANCOVAs with depression scores as covariate and polynomial contrasts revealed that the age-matched control group performed better than the CS and older subject groups in visual target detection, trail making test, stroop task, digit symbol substitution, block design, object assembly, visual reproduction, spatial memory and similarities. The CS and older subjects performed similarly on these tasks. Further, a principal component analysis revealed two significant factors, representing general cognitive function and verbal memory explaining 39.9% and 10.0% of the variance, respectively. Additional MANCOVAs with depression as a covariate revealed that CS and older control subjects showed impaired performance on general cognitive function compared to age-matched controls. These results suggest that hypersecretion of GCs has “aging-like” effects on cognitive performance in individuals with CS.     

Integration of weight and distance information in young children: The role of relational complexity

Young children's integration of weight and distance information was examined using a new methodology that combines a single-armed apparatus with functional measurement. Weight and distance values were varied factorially across the item set. Children estimated how far the beam would tilt when different numbers of weights were placed at different distances from the pivot. There was a developmental progression from non-systematic responding (3-year-olds) to responding based on a single variable, usually weight (4-year-olds) to responding based on integration of weight and distance (5-, 6- and 7-year-olds). Individual analyses revealed additive and multiplicative integration rules in children aged from 5 years. Weight–distance strategy complexity increased with age and was associated with better performance on independent measures of relational processing, especially the more complex items. Thus weight–distance integration involves processing of complex relational information. The findings enhance the explanatory power of Relational Complexity theory as a domain-general approach to cognitive development.     

Vacuuming with my mouth?: Children's ability to comprehend novel extensions of familiar verbs

Can 6- and 8-year-olds (and adults) comprehend common instrument verbs when extended to novel situations? Participants heard eight unusual extensions of common verbs and were asked to paraphrase the verbs’ meanings. Half of the verbs used were specified instrument verbs that include the name of the instrument used to perform the action (e.g., a vacuum is used to vacuum); the other half were open instrument verbs (e.g., write) whose function can be performed with a range of objects. Results suggest that children's ability to interpret verb extensions increases with age, that open instrument verb extensions were more difficult to comprehend than specified instrument verb extensions and that performance on verb extension correlates with scores on a standardized test of language acquisition. Verb knowledge continues to develop well beyond the preschool years.     

Memory for disguised same- and cross-race faces: The eyes have it

According to research on the cross-race effect, through experience, observers learn which diagnostic facial features are important for recognizing same-race compared to cross-race faces. These diagnostic facial features differ across racial groups; whereas the upper facial region is more diagnostic for White faces, the lower facial region is more diagnostic for Black faces. We tested how disguises at encoding (sunglasses [upper region] or bandana [lower region]) affect White and Black observers’ recognition memory for White and Black faces. We found that disguises override the diagnosticity of race-specific regions and have similar effects on recognition of same- and cross-race faces. Relative to no disguise, recognition memory was impaired more by disguising upper (sunglasses) than lower (bandana) facial regions. This supports the hypothesis that facial features trump race-specific diagnostic regions, and the eye region provides relatively more diagnostic information than lower facial features.     

Perceptions of Disability as Related to Medical and Social Factors

This study addressed self-perception of disability and the belief that others perceive one to have a disability. Factors from the medical and social models of disability were tested to determine if social factors still play a role in such perceptions when controlling for medical factors. Cross-sectional data from the 1994–1995 National Health Interview Study on Disability (NHIS-D) provided a stratified random sample of 25,805 noninstitutionalized adults. Logistic regression models were used to demonstrate that even controlling for medical factors (e.g., particular disabling conditions and restrictions in activities of daily living), social and vocational factors were significant predictors of disability perception. Ramifications for the theoretical study of disability, social psychology, and disability policy are discussed.     

Utility of personality measurement of clinic patients with insomnia

An assessment study examining the relationship between sleep quality and personality style in individuals presenting to a sleep clinic with symptoms of insomnia was conducted. The protocol entailed standard clinical interviews conducted by a board certified sleep physician and licensed clinical psychologist. Participants were then assessed using a standard interview and the Millon Clinical Multi-axial Inventory III (MCMI-III) A follow-up appointment was conducted to provide interpretation and treatment recommendations from the interview and testing data. The results from a review of 210 cases are presented in terms of their sleep quality and dominant MCMI-III patterns. Preliminary multivariate analyses indicated two common profiles that correspond to the presentation of insomnia symptomology. These clusters were termed "avoidant" and "anxious" profiles, accordingly. Item content analyses were conducted via the Noteworthy Item classification in the MCMI-III manual to determine the viability of a category determined by the authors called Sleep Behavior Preoccupation. Of this sample 17% fit into the category.
