ASSESSING AND PROGRAMMING GENERALIZED BEHAVIORAL REDUCTION ACROSS MULTIPLE STIMULUS PARAMETERS

Generalization across three stimulus parameters was examined for 5 individuals whose self-injurious behavior was maintained by escape from task demands. Prior to treatment, three stimulus parameters (therapist, setting, and demands) were systematically varied across baseline sessions. These variables were held constant during treatment, which consisted of escape extinction. When treatment was completed, three novel stimulus parameters were probed. If the rate of self-injury was high during this probe, treatment was reimplemented with one new stimulus parameter (the other two were the same as in the original treatment condition). Following this second treatment, another probe with three novel stimuli was conducted. If the rate of self-injury was again high, treatment was implemented again while a second stimulus parameter was changed. This sequence continued until generalization was observed across the three parameters. Results showed idiosyncratic differences in generalization. The behavior of 2 subjects showed complete generalization during the first novel probe. A 3rd subject's behavior showed generalization following treatment across two stimulus parameters (setting and therapist). The behavior of the 2 remaining subjects showed a complete lack of generalization across the three parameters; both subjects required training for novelty by randomly varying the stimulus parameters for a substantial number of sessions.     

Role of Attention and Perceptual Grouping in Visual Statistical Learning

Statistical learning has been widely proposed as a mechanism by which observers learn to decompose complex sensory scenes. To determine how robust statistical learning is, we investigated the impact of attention and perceptual grouping on statistical learning of visual shapes. Observers were presented with stimuli containing two shapes that were either connected by a bar or unconnected. When observers were required to attend to both locations at which shapes were presented, the degree of statistical learning was unaffected by whether the shapes were connected or not. However, when observers were required to attend to just one of the shapes' locations, statistical learning was observed only when the shapes were connected. These results demonstrate that visual statistical learning is not just a passive process. It can be modulated by both attention and connectedness, and in natural scenes these factors may constrain the role of stimulus statistics in learning.     

The Structure of Grandparental Role Meaning

The present study explored the viability of Kivnick's 5-factor model of grandparental meaning (Kivnick, 1983), wherein this model was tested and subsequently refined on a sample of traditional grandparents (N = 102), and then cross-validated using a sample of custodial grandparents (N = 101). The data suggested that Kivnick's model of grandparental meaning was untenable in both grandparent samples. Instead, a single-factor model was supported in both samples. This suggests that grandparental meaning is best understood without regard to Kivnick's distinctions (Kivnick, 1983). This may reflect a cohort effect in the meaning of grandparenting, as evidenced in the diversity of roles into which grandparents are thrust, increased role confusion, as well as the idiosyncratic manner in which grandparents are often forced to define their roles in today's society.     

Moderate Aerobic Exercise, T'ai Chi, and Social Problem-Solving Ability in Relation to Psychological Stress

This study evaluated the importance of exercise mode, social problem-solving ability, gender, and age in relation to anxiety and perceived daily hassles. Adult participants were classified as moderate aerobic exercisers, T'ai Chi exercisers, or sedentary via completion of a questionnaire. Social problem-solving ability, state and trait anxiety, and frequency and severity of daily hassles were measured. As predicted, scores indicating effective social problem-solving ability were associated with fewer reported severe daily hassles and with lower scores on state and trait anxiety. For state and trait anxiety, a main effect of exercise mode emerged after age and gender were controlled. A 3-way interaction involving age, gender, and exercise mode suggested that age and gender moderate the effects of exercise on anxiety, that is, the stress-reducing efficacy of different exercise modes may be dependent on a person's age and/or gender. Implications for theory, research, and practice are discussed.     

Defensive self-esteem and aggression in childhood

Research examining the association between self-esteem (SE) and aggressive behavior in childhood has produced mixed findings. Some of the confusion may stem from the fact that researchers have relied on explicit measures of SE, thus conflating two distinct types of positive self-regard: secure SE (characterized by high levels of explicit and implicit SE), and defensive SE (characterized by high levels of explicit but low levels of implicit SE). The current study tested the hypothesis that children with high levels of defensive, but not secure, SE would engage in higher levels of aggressive behavior. Ninety-three children completed measures of both explicit and implicit SE. Teachers assessed children’s level of physical and relational aggression in the school setting. As predicted, there was a positive association between explicit SE and aggression when levels of implicit SE were low, but not when levels of implicit SE were high.     

Situating Work–Family Negotiations Within a Life Course Perspective: Insights on the Gendered Experiences of NCAA Division I Head Coaching Mothers

Despite the progress women have made since the inception of Title IX, many still face discrimination in the sport workplace. Given the assumption that time-use is gendered, the traditional culture of US intercollegiate sport stands in sharp contrast to the evolving notion of work-life balance. This study employed a qualitative life course perspective to examine the experiences of seventeen head coach mothers in NCAA institutions. Results focus on the participants’ historical/social context, biography, relationships, interplay between these factors, and most importantly the role of administrators as life linkages. The results suggest that it is insufficient for managers to view the employee in isolation or to neglect the organizational culture in athletics. Supervisor attention to this, while time and effort-intensive, can impact employee well-being.     

Engaging African Americans in Therapy: Integrating a Public Policy and Family Therapy Perspective

The field of marriage and family therapy faces a growing imperative to reach historically underserved populations. African Americans are a prime example of a minority group in the United States that continues to be underserved by the current mental health system. We integrate Andersen’s (1995, Journal of Health and Social behavior, 36, 1–10) public policy model of health service use with Fox et al. (1995, Journal of Health Care for the Poor and Underserved, 6, 434–468) revision of the rural de facto mental health services model (Regier and Goldberg, 1978, Archives of General Psychiatry, 35, 685–693) to develop a more inclusive and culturally sensitive framework that captures salient factors influencing African Americans’ entry into and engagement in therapy. Recommendations for overcoming barriers and suggestions for future research are presented.     

Attention Bias Modification Treatment for Adolescents With Social Anxiety Disorder

Social anxiety disorder (SAD) tends to emerge during the early teenage years and is particularly refractory to change even when standard evidence-based CBT treatments are delivered. Efforts have been made to develop novel, mechanistic-driven interventions for this disorder. In the present study, we examined Attention Bias Modification Treatment (ABMT) for youth with SAD. Participants were 58 adolescents (mean age = 14.29 years) who met diagnostic criteria for SAD and who were randomized to ABMT or a placebo control condition, Attention Control Training (ACT). We predicted that ABMT would result in greater changes in both threat biases and social anxiety symptoms. We also explored potential moderators of change including the severity of social anxiety symptoms, the level of threat bias at pretreatment, and the degree of temperament-defined attention control. Contrary to our hypotheses, changes in attention bias were not observed in either condition, changes in social anxiety symptoms and diagnosis were small, and significant differences were not observed between the ABMT and ACT conditions. Little support for the proposed moderators was obtained. Reasons for our failure to find support for ABMT and its potential moderators are explored and recommendations for changes in the ABMT paradigm are suggested.     

Performance on phonological and grammatical awareness metalinguistic tasks by children who stutter and their fluent peers

This study was undertaken to examine the performance of 23 children who stutter (CWS) and 23 children who do not stutter (CWNS) on three metalinguistic tasks. These included two phonological awareness assessment procedures (The Lindamood Auditory Conceptualization Test (LAC) and a Phoneme Reversal Task) and one modified Grammar Judgments Task where syntactic and semantic appropriateness of sentences was evaluated. Differences between groups were significant for the grammar judgment task, where CWNS outperformed CWS in judging syntactically and semantically anomalous sentences. Group differences were not significant for the phonological awareness tasks. The results underscore the importance of examining metalinguistic abilities of CWS through a variety of tasks. EDUCATIONAL OBJECTIVES: The reader will learn about and be able to: (1) recognize the relevance of examining metalinguistic abilities within the context of research on language-stuttering dynamics; and (2) identify measures of metalinguistic abilities that can be used to compare the performances of CWS and CWNS.
