Infant placement and language exposure in daily life

Children's daily contexts shape their experiences. In this study, we assessed whether variations in infant placement (e.g., held, bouncy seat) are associated with infants' exposure to adult speech. Using repeated survey sampling of mothers and continuous audio recordings, we tested whether the use of independence-supporting placements was associated with adult speech exposure in a Southeastern U.S. sample of 60 4- to 6-month-old infants (38% male, predominately White, not Hispanic/Latinx, from higher socioeconomic status households). Within-subject analyses indicated that independence-supporting placements were associated with exposure to fewer adult words in the moment. Between-subjects analyses indicated that infants more frequently reported to be in independence-supporting placements that also provided posture support (i.e., an exersaucer) were exposed to relatively fewer adult words and less consistent adult speech across the day. These findings indicate that infants' opportunities for exposure to adult speech ‘in the wild’ may vary based on immediate physical context.     

Reduction in chemistry - a second response to Scerri

In this rejoinder to Eric Scerri's response to my first comment on his paper on the reduction of chemistry to physics, the main point concerns laws in chemistry. But other themes touched upon include the assumptions involved in ab initio calculations, the question of what is reduced to what on Scerri's view, and the significance he attaches to the term “naturalism”.     

Cognitive Behavioral Treatment of PTSD with Comorbid Panic Attacks

Many individuals that experience traumatic events such as sexual and physical assault develop posttraumatic stress disorder (PTSD). More recently, research has indicated that a significant proportion of PTSD sufferers may also have comorbid panic attacks. Although there are several effective treatments that focus on alleviating PTSD symptoms, until now there were no treatments that focused on also treating comorbid panic attacks. Multiple channel exposure therapy (M-CET) is the first treatment developed to specifically treat comorbid PTSD and panic attacks. It is also unique in that it has been used to treat women who have multiple trauma histories as well as a wide range of different types of traumatic event exposure in a group format. This treatment is described in a session by session format and special considerations in implementing the treatment are discussed.     

Reliability and validity of a new scale to measure prejudice: The GRISMS

The goal of the present research was to assess the reliability and validity of the fiftyitem Modified Godfrey-Richman ISM Scale (M-GRISMS). The sample consisted of seventy-one female and sixty male introductory psychology students. Test items included various ethnic groups (Racism subscale), religious groups (Religion subscale), and the Heterosexist and Sexist subscales. Each of these was parsed into various subcategories, e.g., the Racism subscale assessed attitudes toward African-Americans, Asian-Americans, European-Americans, Hispanics, and Native Americans. The final version of the M-GRISMS (the M-GRISMS-M) was found to be highly reliable and valid. Eight independent factors traversed two or more “isms.”     

Asymmetries in finger-tapping interference produced by mental versus manual rotation of Shepard and Metzler type objects

Two experiments were conducted using dual-task finger-tapping procedures to examine cerebral hemisphere laterization for mental versus manual rotation. Actual three-dimensional block-designs based on Shepard and Metzler's (1971) abstract three-dimensional cubes were constructed. Forty-eight right-handed introductory psychology students participated in each study. The first experiment showed greater right-hand than left-hand interference for mental rotation implicating more left-hemisphere involvement. In contrast, more left-hand than right-hand finger-tapping disruption with manual rotation was observed suggesting more right-hemisphere involvement. A second experiment was conducted to determine if the right-hemisphere involvement found with manual rotation was due to the manual activity of handling and rotating the blocks. Results showed that dual-task interference produced by irrelevant manual rotation combined with mental rotation was not lateralized. Thus, the pattern of results indicate that the manipulospatial processing required in the first experiment was responsible for the asymmetry implicating right-hemisphere involvement.     

Further examination of the psychometric properties of the comprehensive effects of alcohol questionnaire

Although the expectancies component of the Comprehensive Effects of Alcohol Questionnaire has previously been shown to be factorially valid, the factor structure of its valuations component has not previously been examined. The aims of this paper were: (i) to replicate the factor structure of the expectancies items; (ii) to explore the factor structure of the valuations items; and (iii) to investigate the utility of using the Comprehensive Effects of Alcohol Questionnaire to predict drinking behavior. The questionnaire was administered to 1004 university students along with measures of quantity and frequency of alcohol consumption. Fromme, Stroot, and Kaplan's (1993) factor structure of the expectancies scales was replicated. The factor structures of the negative valuations scales were characterized by 2 rather than 3 factors. Negative expectancies improved upon the prediction of drinking quantity and frequency over-and-above positive expectancies, and valuations further improved prediction over-and-above expectancies. Theoretical and clinical implications are discussed.     

Social Control of Health Behaviors in Marriage1

Married couples (N= 69) reported on their use of social control strategies in attempting to modify each other's health behaviors, as well as their affective and behavioral responses to experiencing health‐related social control. Experiencing more negative social control was associated with the tendency to engage in potentially health‐compromising behaviors, whereas experiencing positive social control was associated with attempts to engage in the desired behavior. Most associations between experiencing social control and the target's behavioral responses could be accounted for, at least partially, by the target's affective responses to the social control attempts. These results suggest that current conceptualizations of the health‐relevance of social control are in need of revision. Implications of these results for social control measurement and theory are discussed.     

Qualitative Study of Suicidality and Help-Seeking Behaviors in African American Adolescents

This qualitative study explores adolescents’ perceptions of help-seeking behaviors in the context of a hypothetical suicide crisis. Cauce and colleague’s (2002, Journal of Consulting and Clinical Psychology, 70, 44–55) model was used to examine help-seeking behaviors in 3 domains: problem recognition, decision to seek help, and selection of helpers. Forty-two church-going African American adolescents participated in 1 of 6 focus groups that discussed ways to help a hypothetically suicidal student in a vignette. Findings suggest that although the majority of youth had been exposed to a suicidal peer (76%), they were unsure of the seriousness of suicide as a problem in the African American community. The findings suggest that youth were less comfortable with formal interventions in school, religious institutions or traditional mental health settings. However, youth were open to community-based programs that could be located in school, church or community settings if helpers were: young adults, empathic listeners, non-judgmental, maintained confidentiality, and viewed as “natural helpers”. Implications for developing church-based suicide interventions are discussed. This study was supported by a K-01 Career Development Award from NIMH
