Assessing categorization performance at the individual level: a comparison of Monte Carlo simulation and probability estimate model procedures

Two analytical procedures for identifying young children as categorizers, the Monte Carlo Simulation and the Probability Estimate Model, were compared. Using a sequential touching method, children aged 12, 18, 24, and 30 months were given seven object sets representing different levels of categorical classification. From their touching performance, the probability that children were categorizing was then determined independently using Monte Carlo Simulation and the Probability Estimate Model. The two analytical procedures resulted in different percentages of children being classified as categorizers. Results using the Monte Carlo Simulation were more consistent with group-level analyses than results using the Probability Estimate Model. These findings recommend using the Monte Carlo Simulation for determining individual categorizer classification.     

The Association Between Religious Beliefs and Practices and End-of-Life Fears Among Members of the Presbyterian Church (U.S.A)

This study examines the association between various religious beliefs and practices and fears pertaining to death and dying in a national sample of liberal Protestant U.S. adults. Data were analyzed from a 2002 survey of members and elders of the Presbyterian Church (U.S.A) (N = 935). Four measures of religion were tested together in models predicting four end-of-life fears. Church attendance (p < .01), other church involvement (p < .05), and belief in life after death (p < .001) had negative associations with the fear of what happens after death. Private devotion was inversely related to the fear of dying in pain (p < .05). Involvement in church activities (p < .05), aside from religious services, was inversely related to the fear of leaving loved ones behind. Females tended to be more fearful than males of dying alone and dying in pain and older adults tended to be less fearful than younger adults of the unknown and of leaving loved ones behind.     

Preliminary Efficacy of an Intervention to Reduce Psychosocial Stress and Improve Coping in Low-Income Families

This article reports pre-post intervention results from a randomized controlled trial evaluating the initial efficacy of a couples-based intervention aimed at teaching skills for coping with stress and improving relationship skills in a sample of 173 ethnically diverse low-income co-resident mothers and fathers who were raising at least one child together. Couples were randomly assigned to one of three interventions or to an assessment-only control condition. The Fatherhood, Relationship, and Marriage Education (FRAME) intervention is a 14-h psychoeducation intervention developed specifically to strengthen the ability of low-income mothers and fathers to reduce conflict, cope with stress, and co-parent effectively. Three versions of FRAME were assessed: a men-only group, a women-only group, and a couple's group. The pre-post intervention analyses revealed reductions in financial stress, disengagement coping, and involuntary disengagement responses, as well as improvements in problem solving. These pre-post changes on stress and coping variables were both statistically significant and reliable as assessed by the Reliable Change Index (Jacobson and Truax 1991). Results were particularly strong for the couples' and women's groups. In addition, positive pre-post changes on stress and coping variables were associated with pre-post reductions on symptoms of depression for participants assigned to an intervention. The results demonstrate that participants in FRAME acquire some of the key skills taught in the intervention, and skills acquisition appears to translate into symptom reduction. In addition, this study highlights the value of an intervention aiming to improve the capacity of parents with economic hardship to cope effectively with stress.     

Impact of Stress Reduction Interventions on Hostility and Ambulatory Systolic Blood Pressure in African American Adolescents

This study examined the impact of breathing awareness meditation (BAM), life skills (LS) training, and health education (HE) interventions on self-reported hostility and 24-hour ambulatory blood pressure (ABP) in 121 African American (AA) ninth graders at increased risk for development of essential hypertension. They were randomly assigned to BAM, LS, or HE and engaged in intervention sessions during health class for 3 months. Before, after, and 3 months following intervention cessation, self-reported hostility and 24-hour ABP were measured. Results indicated that between pre- and postintervention, BAM participants displayed significant reductions in self-reported hostility and 24-hour systolic ABP. Reductions in hostility were significantly related to reductions in 24-hour systolic ABP. Between postintervention and follow-up, participants receiving LS showed a significant reduction in hostility but not in 24-hour ABP. Significant changes were not found for the HE group in 24-hour ABP or self-reported hostility, but these change scores were significantly correlated. The implications of the findings are discussed with regard to behavioral stress reduction programs for the physical and emotional health of AAs.     

The role of inhibitory control in behavioral and physiological expressions of toddler executive function

A total of 81 toddlers (24-27 months of age) participated in a biobehavioral investigation of inhibitory control. Maternal report measures of inhibitory control were related to laboratory tasks assessing inhibitory abilities under conditions of conflict, delay, and compliance challenge as well as toddler verbal ability. In addition, unique variance in inhibitory control was explained by task-related changes in brain electrical activity at lateral frontal scalp sites as well as concurrent inhibitory task performance. Implications regarding neural correlates of executive function during early development and a central organizing role of inhibitory processing during toddlerhood are discussed.     

Perception of object-context relations: eye-movement analyses in infants and adults

Twenty-eight 4-month-olds' and twenty-two 20-year-olds' attention to object-context relations was investigated using a common eye-movement paradigm. Infants and adults scanned both objects and contexts. Infants showed equivalent preferences for animals and vehicles and for congruent and incongruent object-context relations overall, more fixations of objects in congruent object-context relations, more fixations of contexts in incongruent object-context relations, more fixations of objects than contexts in vehicle scenes, and more fixation shifts in incongruent than congruent vehicle scenes. Adults showed more fixations of congruent than incongruent scenes, vehicles than animals, and objects than contexts; equal fixations of animals and their contexts but more fixations of vehicles than their contexts; and more shifts of fixation when inspecting animals in context than vehicles in context. These findings for location, number, and order of eye movements indicate that object-context relations play a dynamic role in the development and allocation of attention.     

Where's the Action? Understanding What Works and Why in Relationship Education

The field of couples relationship education has come to a critical junction. We have generally demonstrated that our interventions work (at least in the short run) but to what extent have we shown that the skills and processes we teach are in fact responsible for the success of the intervention? In this paper we review progress made in understanding mechanisms of change in relationship education, explore limitations of this body of research, explicate the barriers that interfere with progress in understanding mechanisms of change in intervention research, and present recommendations on how to proceed from here. Although our goal in this paper is to focus more on issues in the field rather than to present a comprehensive review of the literature, we provide overarching research summaries to illustrate some of our points. We conclude with offering recommendations for the next generation of research in the couples relationship education field.     

Passive coping response to depressive symptoms among low-income homebound older adults: Does it affect depression severity and treatment outcome?

Due to their homebound state, lack of financial resources, and/or other life demands, a significant proportion of depressed, low-income homebound older adults experience depression. Because of their limited access to psychotherapy, most of these older adults self-manage their depressive symptoms. The purposes of this study were to examine (1) the relationship between homebound older adults' coping responses to depressed mood and the severity of their depressive symptoms at baseline (n = 121), and (2) the moderating effect of passive coping responses on the relationship between participation in problem-solving therapy (PST: in-person or telehealth delivery) and depressive symptoms at 12- and 24-week follow-ups. Controlling for the effects of demographic and disability characteristics, cognitive passive coping was significantly associated with baseline depressive symptoms, while behavioral passive coping was not. The main effect of baseline cognitive passive coping response was also significant in mixed-effects regression analysis, but the interaction between coping pattern and group was not significant. The results point to a possibility that cognitive passive copers may have benefited as much from PST as the rest of the PST participants. Further research needs to examine the moderating effect of coping responses to depressive symptoms on treatment efficacy of PST and other psychosocial interventions for late-life depression.
