Stimulus averaging and the context for judgment

Loudness judgments of stimulus sets composed of four bursts of noise were analyzed for two types of contextual effects: between-set and within-set. Experiment I demonstrated between-set effects for these four-component stimuli; they were shown to be similar to those found in previous work with single stimuli. Experiment 2 tested an averaging model for within-set contextual effects. The results were inconsistent with the model. One interpretation is that there are within-set effects and that these are caused by shifts in the effective range of stimuli. Alternative interpretations attribute the apparent contextual effects either to an averaging of physical values or to an inappropriate scale of judgment.     

Duty-Related Posttraumatic Stress Symptoms in 911 Telecommunicators: The Roles of Childhood Trauma Exposure and Emotion-Focused Coping

A history of childhood trauma exposure has been linked to the development of posttraumatic stress symptoms in adulthood following new exposure. Unhealthy coping behaviors that could develop or be utilized in response to early trauma could lend themselves to psychological issues in adulthood. Emotion-focused and problem-focused coping strategies in relation to stressful duty-related situations are examined as indirect pathways through which childhood trauma exposure could be associated with duty-related posttraumatic stress symptoms in 911 telecommunicators (N = 808). Multiple mediation models revealed that 3 of the 4 emotion-focused coping strategies, but not the problem-focused strategies, functioned as significant mediators in the association between childhood exposure and duty-related posttraumatic stress symptoms. Pairwise comparisons showed that self-controlling and escape-avoidance strategies were the strongest pathways of the indirect childhood trauma exposure–posttraumatic stress symptoms association. Implications of results regarding coping in response to new traumatic events in adulthood and potential research and intervention directions are discussed.     

Social–Emotional Factors and Academic Outcomes Among Elementary‐Aged Children

Social–emotional comprehension involves encoding, interpreting, and reasoning about social–emotional information, and self‐regulating. This study examined the mediating pathways through which social–emotional comprehension and social behaviour are related to academic outcomes in two ethnically and socioeconomically heterogeneous samples totaling 340 elementary‐aged children. In both samples, social–emotional comprehension, teacher report of social behaviour, and academic outcomes were measured in a single school year. In both samples, structural equation models showed that the relationship between social–emotional comprehension and reading was mediated by socially skilled behaviour. In one sample, but not the other, the relationship between social–emotional comprehension and math was mediated by socially skilled behaviour. This paper advances our understanding of the mechanisms through which social–emotional factors are associated with academic outcomes. Copyright © 2015 John Wiley & Sons, Ltd.     

The Munroe-Meyer Approach: Continuous Integration of Didactic Instruction,Research, and Clinical Practice

Increased demand for applied behavior analysis (ABA) services has increased the need for additional masters-level practitioners and doctoral-level academicians and clinical directors. Based on these needs, the University of Nebraska Medical Center’s (UNMC) Munroe-Meyer Institute has developed a PhD program. The academic structure at UNMC allowed us to create our PhD program in a relatively quick and efficient manner. Our PhD program has many unique features, including (a) close integration of didactic instruction with clinical and research training provided by leading experts in ABA in which students immediately apply concepts introduced in the classroom during coordinated clinical and research practica; (b) structured grant writing training in which students learn to write and submit an NIH-level grant; (c) financial support in the form of a stipend of $23,400 per year, free health benefits, and a full-tuition waiver for up to 12 credits per semester for UNMC courses (a benefits package worth approximately $50,000 per year for an out-of-state student); and (d) encouragement and financial support to present papers at local, regional, and national behavior analysis conferences.
