Perception of emotional expression in musical performance

Expression in musical performance is largely communicated by the manner in which a piece is played; interpretive aspects that supplement the written score. In piano performance, timing and amplitude are the principal parameters the performer can vary. We examined the way in which such variation serves to communicate emotion by manipulating timing and amplitude in performances of classical piano pieces. Over three experiments, listeners rated the emotional expressivity of performances and their manipulated versions. In Experiments 1 and 2, timing and amplitude information were covaried; judgments were monotonically decreasing with performance variability, demonstrating that the rank ordering of acoustical manipulations was captured by participants' responses. Further, participants' judgments formed an S-shaped (sigmoidal) function in which greater sensitivity was seen for musical manipulations in the middle of the range than at the extremes. In Experiment 3, timing and amplitude were manipulated independently; timing variation was found to provide more expressive information than did amplitude. Across all three experiments, listeners demonstrated sensitivity to the expressive cues we manipulated, with sensitivity increasing as a function of musical experience.     

Factors Affecting Mental Health of North Indian Adolescents

The study explored the different factors that affect mental health of adolescents. A total of 1209 adolescents participated of which 591 adolescents responded in English and 618 adolescents responded in Hindi. The participants were given a language choice. About 1089 adolescents were attending school and 120 adolescents were school dropouts. In the current study, original tripartite structure of Hindi-translated Mental Health Continuum Short Form was confirmed. The measurement invariance results indicated that Mental Health Continuum Short Form is a valid scale in English and Hindi languages. Multivariate results indicated age group (early vs. middle vs. late), type of school (government vs. private), place of residence (urban vs. rural), ability to express thoughts and opinion in front of parents, presence of relaxed environment at home and satisfaction with dressing style affected adolescent’s mental health. Adolescents attending school displayed better mental health functioning than drop outs.     

Individual differences,aging, and IQ in two-choice tasks

The effects of aging and IQ on performance were examined in three two-choice tasks: numerosity discrimination, recognition memory, and lexical decision. The experimental data, accuracy, correct and error response times, and response time distributions, were well explained by Ratcliff’s (1978) diffusion model. The components of processing identified by the model were compared across levels of IQ (ranging from 83 to 146) and age (college students, 60–74, and 75–90 year olds). Declines in performance with age were not significantly different for low compared to high IQ subjects. IQ but not age had large effects on the quality of the evidence that was obtained from a stimulus or memory, that is, the evidence upon which decisions were based. Applying the model to individual subjects, the components of processing identified by the model for individuals correlated across tasks. In addition, the model’s predictions and the data were examined for the “worst performance rule”, the finding that age and IQ have larger effects on slower responses than faster responses.     

A Review of Symptoms Commonly Associated with Menopause: Implications for Clinical Neuropsychologists and Other Health Care Providers

Menopause is a process, either naturally or medically induced, that occurs in nearly all women at some point in life. Some of the most commonly reported symptoms associated with menopause are hot flushes/flashes, fatigue, headaches, irritability, insomnia, and depression. These symptoms overlap with symptoms commonly reported in Traumatic Brain Injury (TBI) as well as postconcussive syndrome. This overlap between symptoms commonly associated with menopause and neuropsychological conditions makes it necessary to have the base rates of these symptoms and conditions available. The purpose of the present review was to consolidate the clinical literature on the most commonly reported menopausal symptoms and to calculate the base rates associated with these symptoms.     

Application of the diffusion model to two-choice tasks for adults 75-90 years old

The effects of aging on simple 2-choice decision making was investigated with the diffusion model (R. Ratcliff, 1978). Data for 75- to 90-year-olds were collected and compared with previous data from 60- to 75-year-olds and college students for 5 tasks: a signal detection-like task, letter and brightness discrimination with masking, recognition memory, and lexical decision. The model fit the data well and therefore allows components of processing to be examined as a function of age. Compared with decision-making processes in college students, decision criteria and nondecision components of processing increased with participants' age. However, the quality of the evidence on which decisions were based decreased with age only for letter and brightness discrimination.     

Motivation for and commitment to social values: The roles of age and gender

The primary aim of this study was to examine how motives and commitment to social values influence well-being in men and women of different ages. College students and older adults in the community reported on their motivational orientation (intrinsic vs. extrinsic), behavioral commitment to idiographic social values, and their current well-being (satisfaction with life, positive and negative affect). We tested a series of path models with motivational orientation mediating the relationship between commitment to values and well-being. Consistent with self-determination theory, we found that behavioral commitment to intrinsically motivating social values was related to greater life satisfaction and positive affect, whereas being committed to extrinsically motivating values was related to greater negative affect. While age and gender did not moderate these relationships, meaningful age and gender differences emerged across value-based motivations, commitment, and indices of well-being. This work adds to our understanding of how values are a guiding influence for successful navigation of one’s social world.     

Gender Ideology and Social Transformation: Using Mixed Methods to Explore Processes of Ideological Change and the Promotion of Women’s Human Rights in Tanzania

Despite growing international interest in policies and practices to enhance women’s status and well-being in the Global South, ideological constraints to structural transformation and increasing opportunities available to women are widespread. There is thus considerable need to examine how ideological processes surrounding women’s status and value can be challenged. In the current study we used mixed method analyses to examine a process of deideologization—the contestation and transformation of traditional ideology—among a group of Maasai women in northern Tanzania. First, thematic analysis was used to analyze qualitative interviews conducted with 16 Maasai women. Themes involving traditional ideology, the value of popular education, and components of a deideologization process were identified and assessed. Second, quantitative structural equation modeling was used to test a process model connecting women’s participation in popular education classes to increased political efficacy, decreased discomfort speaking at community meetings, and, in turn, deceased patriarchal beliefs about women. Overall, findings provided evidence for an iterative deideologization process catalyzed by popular education that led to improvements in women’s lives. The importance of promoting processes of deideologization via locally driven efforts to improve the status and well-being of women are discussed.
