Differential impacts of age of acquisition on letter and semantic fluency in Alzheimer's disease patients and healthy older adults

The degree to which the typical age of acquisition (AoA) of words and word frequency have separable influences on verbal production tasks has been strongly debated. To examine the overlap between these factors in verbal fluency tasks, the performance of Alzheimer's disease (AD) patients (N = 34) and normal elderly controls (N = 36) was compared on semantic (e.g., vegetables) and letter (e.g., words that begin with F) fluency tasks. These comparisons revealed that words generated for the semantic fluency task had an earlier AoA while words generated for the letter fluency task had a higher word frequency. Differences in AoA between AD patients and controls were larger for semantic than letter fluency. These results suggest that AoA has an effect on verbal production that is independent of word frequency and that AoA has a semantic locus.     

Prior and future withdrawal and performance: A meta-analysis of their relations in panel studies

While consensus exists among researchers that withdrawal and performance are related, the ordering of these constructs in proposed models frequently varies based on the theoretical focus of the study. Specifically, several extant well-being theories predict employee withdrawal will affect future performance while several turnover theories predict employee performance will affect future withdrawal. This study systematically addresses these complementary theories by conducting a meta-analysis of panel studies measuring both withdrawal and performance at two or more time periods. After accounting for sampling and measurement error, meta-analytic regression results indicate that performance is significantly negatively related to future withdrawal (ρ = − .19) even after accounting for prior withdrawal (β = − .03). However, the relationship between withdrawal and future performance (ρ = − .20) disappeared after accounting for prior performance (β = .00), although burnout did predict future performance even after accounting for prior performance (β = − .07).     

An Analysis of Natural Mentoring Relationship Profiles and Associations with Mentees’ Mental Health: Considering Links via Support from Important Others

We explored associations between natural mentoring relationship profiles and young adults’ life satisfaction and symptoms of depression via participants’ perceived support from important others accounting for participants’ perceived support and mental health prior to the onset of their natural mentoring relationships. Participants included 396 young adults (57 % female; mean age = 30.97, SD = .6), the majority of whom identified as Black or African American (79 % Black, 18 % White, 3 % Biracial). Most participants had completed high school but few participants (13 %) had completed degrees from 4 year institutions. We used a latent profile approach to identify natural mentoring relationship profiles and employed structural equation modeling to test our study hypotheses. Slightly over half of study participants (53 %) reported the presence of a natural mentor in their lives since the age of 14. Results suggest that natural mentoring relationships characterized by high levels of relational closeness and either extended relationship duration or frequent contact may promote improvements in psychological well-being among mentees over time via greater experiences of social support from important others.     

Effects of hearing and vision impairments on the Montreal Cognitive Assessment

Many standardized measures of cognition include items that must be seen or heard. Nevertheless, it is not uncommon to overlook the possible effects of sensory impairment(s) on test scores. In the current study, we investigated whether sensory impairments could affect performance on a widely used screening tool, the Montreal Cognitive Assessment (MoCA). Three hundred and one older adults (mean age = 71 years) completed the MoCA and also hearing and vision tests. Half of the participants had normal hearing and vision, 38% impaired hearing, 5% impaired vision, and 7% had dual-sensory impairment. More participants with normal sensory acuity passed the MoCA compared to those with sensory loss, even after modifying scores to adjust for sensory factors. The results suggest that cognitive abilities may be underestimated if sensory problems are not considered and that people with sensory loss are at greater risk of cognitive decline.     

Acts of Remembering: Relationship in Feminist Therapy

This article is an act of remembering. In the first part of this article, the author remembers and reflects upon her own journey of being and becoming a feminist, healer and clinical psychologist in training. She then shares some of the most meaningful lessons on 1) the therapeutic alliance, 2) transference and countertransference, 3) the nature of change, and 4) cultural competence that she has learned from her sister of the heart relationship with the brilliant spirit and work of Black lesbian, feminist, warrior poet, and activist, Audre Lorde. In each of these lessons the author reflects on her efforts to translate her conceptual or applied practice as a feminist student therapist. It is her hope to invite exploration of new bridges and paths by which other feminist psychologists may connect more deeply and meaningfully to our work both professionally and personally. The author closes with some reflections on the path ahead for feminist psychology.     

The Effects of Object Weight on the Kinematics of Prehension

The purpose of these experiments was to determine the effects of object weight and condition of weight presentation on the kinematics of human prehension. Subjects performed reaching and grasping movements to metal dowels whose visible characteristics were similar but whose weight varied (20, 55, 150, 410 g). Movements were performed under two conditions of weight presentation, random (weight unknown) and blocked (weight known). Three-dimensional movements of the thumb, index finger, and wrist were recorded, using a WATSMART system to obtain information regarding the grasp and transport components. The results of the first experiment indicated that object weight and condition of presentation affected the temporal and kinematic measures for both the grasp and transport components. In conjunction with the results of a second experiment, in which time in contact with the dowel was measured, it was shown that the free-motion phase of prehension (i.e., up to object contact) was invariant over the different conditions, however. The changes were observed in the finger-object interaction phase (when subjects applied forces after contact with the dowel), prior to lift-off. These results were interpreted as indicating (a) object weight does not influence the planning and execution of the free-motion phase of prehension and (b) there are at least two motor control phases involved in prehension, one for making contact with the object and the other for finger-object interaction. The changing contributions of visual, kinesthetic, and haptic information during these two phases is discussed.     

Predictive Criterion-Related Validity of Observer Ratings of Personality and Job-Related Competencies Using Multiple Raters and Multiple Performance Criteria

The purpose of this study was to assess the predictive validity of observer ratings of personality and job-related competencies in a selection setting. Based on ratings from multiple raters of both the predictors and the criteria in a sample of MBA students, results indicated that observer ratings of Conscientiousness, Emotional Stability, leadership, and interpersonal skills predicted work performance, team performance, and academic performance. For work performance and team performance, a composite of the four predictors had incremental predictive validity over general mental ability, even after controlling for how well the rater knew the ratee.     

Natural Mentors, Mental Health, and Risk Behaviors: A Longitudinal Analysis of African American Adolescents Transitioning into Adulthood

Patterns of substance use are examined in a sample of over 1,200 youth in a non-metropolitan region of New England. Self-reported history and frequency of alcohol, tobacco, marijuana, inhalants, pain medications, and other hard drug use was assessed for 9th and 10th grade students. Latent class analyses identified four patterns of substance use: non-users (22%), alcohol experimenters (38%), occasional polysubstance users (29%), and frequent polysubstance users (10%). Contextual risk and protective factors in the individual, family, peer, and community domains predicted substance use patterns. Youth report of peer substance use had the largest effects on substance use class membership. Other individual characteristics (e.g., gender, antisocial behavior, academic performance, perceived harm from use), family characteristics (e.g., parental drinking, parental disapproval of youth use), and community characteristics (e.g., availability of substances) demonstrated consistent effects on substance use classes. Implications for prevention are discussed from a social-ecological perspective.     

Alcohol Availability and Violence among Inner-City Adolescents: A Multi-Level Analysis of the Role of Alcohol Outlet Density

Researchers recognize that the connection between alcohol and peer violence may relate to community level ecological factors, such as the location of businesses that sell alcohol. Building on previous research among adults, this study examines the relationship between alcohol outlet density and violent behaviors among adolescents, taking into account demographic characteristics, individual alcohol use, and neighborhood level socioeconomic indicators. Data drawn from a diverse Emergency Department based sample of 1,050 urban adolescents, combined with tract level data from the state liquor control commission and U.S. Census, were analyzed. Results of multivariate multi-level regression analysis indicate that alcohol outlet density is significantly related to adolescents’ violent behaviors, controlling for demographic characteristics and individual alcohol use. Census tract level socioeconomic indicators were not significantly associated with youth violence. Findings suggest that alcohol outlet density regulation should be considered as part of broader violence prevention strategies for urban adolescents.
