A naturalistic study of the word frequency effect in episodic recognition

In order to separate the effects of experience from other characteristics of word frequency (e.g., orthographic distinctiveness), computer science and psychology students rated their experience with computer science technical items and nontechnical items from a wide range of word frequencies prior to being tested for recognition memory of the rated items. For nontechnical items, there was a curvilinear relationship between recognition accuracy and word frequency for both groups of students. The usual superiority of low-frequency words was demonstrated and high-frequency words were recognized least well. For technical items, a similar curvilinear relationship was evident for the psychology students, but for the computer science students, recognition accuracy was inversely related to word frequency. The ratings data showed that subjective experience rather than background word frequency was the better predictor of recognition accuracy.     

Sexual Risk-Taking Behaviors Among Adolescents with Severe Emotional Disturbance

We investigated the sexual risk-taking behaviors of adolescents with severe emotional disturbance (SED). Subjects (N = 70) were clients of the South Carolina Continuum of Care. Information on sexual intercourse, sexual risk-taking, aggressive behaviors, substance use, and suicidal behavior was gathered using a modified version of the US Centers for Disease Control and Prevention self-report Youth Risk Behavior Survey. Forty-two percent of each race-gender group reported first intercourse before age 13, except for African American females at 63%. Seventy-five to 79% of all race-gender groups reported first sexual intercourse by age 18. Drinking alcohol before age 13 and carrying a weapon in the past 30 days were associated with first intercourse before age 13. Youth reporting first intercourse between ages 13 and 18 were about 12 times more likely to report suicide ideation than those youth who reported never having sexual intercourse. Youth with SED reporting first intercourse before age 13 appear to have an increased risk for unintended pregnancy and for contracting a sexually transmitted disease compared to youth with SED reporting first intercourse after age 13.     

Worlds within Worlds: Kabbalah and the New Scientific Paradigm

Beginning with relativity and quantum theory, the deterministic view that has dominated and shaped Western culture for more than 2,500 years has begun to unravel, leading to the emergence of a new paradigm. This new paradigm effectively reformulates the project of science, conceiving of existence as an interpenetrating web of coevolving, cocreative relationships. By exploring Kabbalah and the new scientific paradigm within the context of shared evolutionary principles, I seek to demonstrate a viable alternative to the prevailing deterministic worldview. By going beyond the limits of determinism and re–visioning existence as an evolutionary, emergent phenomenon, we can establish a new basis for an authentic dialogue between science and religion.     

Intersensory redundancy accelerates preverbal numerical competence

Intersensory redundancy can facilitate animal and human behavior in areas as diverse as rhythm discrimination, signal detection, orienting responses, maternal call learning, and associative learning. In the realm of numerical development, infants show similar sensitivity to numerical differences in both the visual and auditory modalities. Using a habituation-dishabituation paradigm, we ask here, whether providing redundant, multisensory numerical information allows six-month-old infants to make more precise numerical discriminations. Results indicate that perceptually redundant information improved preverbal numerical precision to a level of discrimination previously thought attainable only after additional months of development. Multimodal stimuli may thus boost abstract cognitive abilities such as numerical competence.     

Using full matching to estimate causal effects in nonexperimental studies: examining the relationship between adolescent marijuana use and adult outcomes

Matching methods such as nearest neighbor propensity score matching are increasingly popular techniques for controlling confounding in nonexperimental studies. However, simple k:1 matching methods, which select k well-matched comparison individuals for each treated individual, are sometimes criticized for being overly restrictive and discarding data (the unmatched comparison individuals). The authors illustrate the use of a more flexible method called full matching. Full matching makes use of all individuals in the data by forming a series of matched sets in which each set has either 1 treated individual and multiple comparison individuals or 1 comparison individual and multiple treated individuals. Full matching has been shown to be particularly effective at reducing bias due to observed confounding variables. The authors illustrate this approach using data from the Woodlawn Study, examining the relationship between adolescent marijuana use and adult outcomes.     

Approaching math increases math = me and math = pleasant

In two studies, we examined the effect of extensive practice in approaching math on implicit identification with math, implicit math attitudes, and behavior during a math test. The results from Study 1 demonstrated that women trained to approach math showed more identification with and positive implicit attitudes toward math than women trained to avoid math. Notably, this latter pattern of findings was only evident for women low in initial identification with this field. The results from Study 2 replicated these findings by showing that women who were initially low in math identification and trained to approach math showed more implicit identification with math and attempted more items on a math test than women trained to respond to math in a neutral way. The implications of these findings for current theorizing on the gender gap in women’s representation in math related careers are discussed.     

Associations between social capital and health status in an Australian population

This study investigated the association between social capital and health related quality of life in a sample of Australian adults. Information was collected from a sample of adults in Queensland, Australia relating to health status, health related quality of life and related social determinants of health by computer-assisted-telephone-interview survey. Significant associations were observed between social capital and physical health when adjusting for selected demographic measures. No significant association was observed between social capital and mental health. The research produced equivocal results regarding the associations between social capital and the selected measures of health-related quality of life. Evidence is presented in support of the association between social capital and physical health status, whereas no associations were observed between mental health status and social capital. The role and relationship between health and social capital remains elusive. More work is required to clearly support social capital's role in physical and mental health and well-being.     

Docile Bodies and Heteronormative Moral Subjects: Constructing the Child and Sexual Knowledge in Schooling

This paper explores the complex relationship between childhood and sexuality by identifying prevailing discourses underpinning the repression and regulation of children’s knowledge of sexuality in Australia since the 1950’s. Examining several primary schooling Health Curricula, and Professional Development, Health and Physical Education Syllabi from the 1950’s to the turn of the new century, we trace the construction of the child and children’s knowledge of sexuality in early childhood (K-6). We believe that teaching sexual knowledge within schooling culture needs to be better aligned with the changing lives of children so as to adequately address different and diverse family experiences.

Gender differences in health anxiety: An investigation of the interpersonal model of health anxiety

Health anxiety (HA) involves persistent worry about one’s health and beliefs one has an illness or may contract a disease. In the present study, gender differences in Noyes et al.’s (2003) interpersonal model of health anxiety (IMHA) were examined. Using a sample of 950 undergraduates (674 women; 276 men), multigroup confirmatory factor analyses suggested the measurement model for key dimensions of the IMHA (i.e., reassurance-seeking, alienation, worry, and absorption) were invariant across gender. This suggests key dimensions of this model are applicable to and generalizable across women and men. Coefficients alpha for and bivariate correlations between these IMHA dimensions were also roughly comparable across women and men. As hypothesized, mean levels of reassurance-seeking and worry were significantly higher in women compared to men. No gender differences were observed in mean levels of alienation or absorption. Reassurance-seeking and worry appear salient in the interpersonal behavior and emotional life of women with HA. The present study helps to clarify gender differences in the IMHA and other HA models involving similar variables.     

Predictors of Recent Mental Health Service Use in a Medical Population: Implications for Integrated Care

This study investigated the relationship between physical and mental health and psychosocial variables and recent (within the last 12 months) mental health service use among 240 medical patients recruited from general and specialty outpatient clinics at an academic medical center. Results indicated 43.3% of the participants had recently received mental health services in the form of psychotropic medication (75%), psychotherapy (2%), or a combination of these treatments (20.2%). Among patients with moderate to severe symptoms of anxiety or depression, approximately two-thirds were receiving mental health treatment. Moreover, four variables (healthcare provider referral for mental health services, perceived need for mental health services, prior use of mental health services, and frequency of medical appointments) were significant unique predictors of recent mental health service use. This suggests collaborative/integrated medical care may increase needed mental health service use.
