The adequacy of a role play of a previous event as affected by high and low social anxiety and rehearsal

This study was designed as a preliminary step in evaluating the adequacy of a role play of a previous event. Sixty undergraduate males, high or low in social anxiety, interacted with a female assistant. Two groups of subjects then rehearsed this conversation overtly or covertly, while a third group became involved in a distraction task. Finally, all subjects role played the initial interaction with a second female assistant. Individual Pearson product-moment correlations between the initial and the role-play sessions yielded moderate, but significant correlations for most of the rated behaviors. Canonical correlations for the verbal and for the nonverbal ratings showed the two sessions, as a whole, highly related. Two (high-versus low-social anxiety group) × three (overt, covert, or no rehearsal) analyses of variance were performed on four measures. Significant results were found only for the anxiety group effect and rehearsal group effect on one rating, anxiety behaviors. The implications of the modest individual correlations suggest that estimation of specific levels of behavior is not appropriate from a role play of a previous event. However, the use of such a role play to make global distinctions of relative competence may be appropriate. The results of this study are consonant with earlier studies on role-play assessment.This article is based on a master's thesis completed by the first author in partial fulfillment of the requirements for the Master of Science degree at Ohio University.     

The executive control of mnemonic activity

The present study focused on the executive monitoring of a rehearsal strategy by sixth (11 years 5 months), tenth (15 years 8 months), and twelfth (17 years 9 months) graders and adults (27 years 4 months). The results showed that all of the adults spontaneously adopted an “optimal” strategy and generalized it to a second task. However, none of the sixth graders and only two tenth and three twelfth graders did so. All of the school subjects subsequently trained to rehearse, maintained the strategy without prompting, and showed evidence of transfer. In comparison to adults, the trained subjects' generalized routines became more similar to the adults' as grade increased. This study supports the notion that efficient executive functioning includes the case where continued use of a mnemonic routine is a reasonable response to an objective change in an information-processing task.     

Manipulation of response-contingent unconditioned-stimulus intensity in human eyelid conditioning: A two-phase model analysis

Four groups of human subjects were given 360 classical eyeblink conditioning trials. All groups received the same UCS (unconditioned stimulus) intensity on[Formula: see text] (nonconditioned response) trials but differed in the intensity presented on CR trials. Response probability increased as a positive function of UCS intensity on CR trials. Phase 1 of the two-phase model was longer when no UCS was presented on CR trials, but did not differ in duration among the remaining three groups. Most subjects could be described with a single operator in Phase 2, the operator limit increasing as a positive function of CR-contingent UCS intensity. For subjects requiring different operator limits on CR and[Formula: see text] trials, the latter was lower with high CR-trial intensities but higher with low CR-trialintensities. The results were interpreted to be more consistent with drive theory than with "law-of-effect" or two-factor theories.     

Defensive burying, nest relocation, and pup transport in lactating female rats

A wire-wrapped wooden dowel was inserted through the wall of the nest compartment of a two-compartment box. There were four conditions. Some lactating female rats were shocked by the dowel when they first touched it, and some were not, after which the dowel was either immediately withdrawn from the chamber or left in place for the duration of the ensuing 30-min test period. Three defensive behaviours were observed during the tests: the mothers buried the shock source with bedding from the floor of the chamber, they transported their pups to the adjoining “safe” chamber, and they built a new nest in the safe chamber from material salvaged from their original nest. The shocked mothers that were confronted with the shock source throughout the test period displayed significantly more of each of these three defensive behaviours than did the mothers in the other three conditions. The methods used in this study provide a simple, reliable, safe paradigm for studying maternal defensive behaviour; the results indicate that the defensive capacities of the rat extend far beyond stereotypical flight, freeze, and fight responses, which have been the focus of most research on rodent defense.     

Understanding the Progression from Early Alcohol Use Experimentation to Alcohol Use Disorder: Testing Vulnerability by Experience Interactions Using a Two-Part Latent Growth Curve Model

Most adolescents experiment with alcohol, but a smaller percentage advance to heavy alcohol use (AU) and AU disorder (AUD). Understanding for whom and how early risk leads to AUD is of interest to prevention, treatment, and etiology of AUD. Informed by developmental and behavioral neuroscience theory, the current study tested whether temperament (effortful control, surgency, and negative affect), peer AU (multi-reporter), and AU with parents’ permission interacted to distinguish youth who experiment with alcohol from those who escalate to AUD. Community adolescents (N?=?765, 53% female) were assessed annually for seven years (M_age?=?11.8, range: 10–13 at Year 1; M_age?=?18.7; range?=?17–20 at year 7). Temperament by early experience interactions were expected to predict amount of AU. Amount of AU was expected to mediate the relationship between the interactions and AUD symptoms (assessed at Years 3 and 7, M_age?=?13.8 and 18.7) above and beyond a range of confounds (e.g., problem behavior and parental AU and AUD). Supporting hypotheses, effortful control and surgency interacted with AU with parents’ permission and peer AU, respectively, to predict higher amount of AU (R²?=?0.47) and AUD symptoms (R²?=?0.03). Results support developmental and behavioral neuroscience theory. High surgency and low effortful control in conjunction with peer AU and AU with parents’ permission were associated with large effects on AU and moderate mediated effects through AU to AUD. AU with parents’ permission was risky at low and high effortful control and protective when peers used alcohol.

     

To Be or Not: A Brief History of the Health Humanities Consortium

The Health Humanities Consortium (HHC) was established in 2015 to “promote health humanities scholarship, education, and practice through transdisciplinary methods and theories that focus on the intersection of the arts and humanities, health, illness, and healthcare.” As the founding co-chairs of the HHC, we provide a history of the founding of this organization in this article, describing the journey of its creation, the choices and challenges it faced as a new organization, and our hopes for a rich future.

     

Comparison of contingent and noncontingent access to therapy dogs during academic tasks in children with autism spectrum disorder

This study compared contingent and noncontingent access to therapy dogs during educational tasks for children with autism spectrum disorder using a multielement design. The experimenters assessed whether initial preference for the dog predicted reinforcer efficacy and how preference changed across time. A higher response rate during contingent dog sessions than baseline sessions occurred for 4 out of 5 participants, suggesting that the dog functioned as a reinforcer. One participant engaged in a high rate of responding in both contingent and noncontingent dog conditions. Preference assessments revealed idiosyncrasies, suggesting that further research is needed into the predictive nature of initial preference assessments with animals as part of the stimulus array. The experimenters also analyzed salivary cortisol before and after sessions to determine if learning about the upcoming interaction with a dog reduced salivary cortisol in children. Cortisol was variable across participants, with only some deriving a potential physiological benefit from expecting to interact with the dog.     

A preliminary evaluation of treatment duration on the resurgence of destructive behavior

Quantitative models of resurgence (e.g., Behavioral Momentum Theory, Resurgence as Choice) suggest that resurgence is partly a function of the duration of extinction exposure, with longer histories of extinction producing less resurgence. This prediction is supported by some laboratory research and has been partially supported by clinical translations that did not isolate the effects of extinction exposure prior to testing for resurgence. The degree to which different histories of extinction impact the likelihood of treatment relapse in therapeutic applications of differential reinforcement is of great interest to the clinical community, including insurance carriers and other financial providers. In the present study, we isolated the effects of extinction history for severe destructive behavior across 6 participants referred for treatment services and examined resurgence of destructive behavior when alternative reinforcement terminated. Our within-subject evaluation showed no difference in the level of resurgence or persistence of destructive behavior following short and long exposures to differential reinforcement with extinction. We discuss our failure to replicate in relation to experimental-design considerations for investigating this and other relapse phenomena in future research with clinical populations.     

Re-exposure to reinforcement in Context A during treatment in Context B reduces ABC renewal

Previous work from our laboratory showed that intermittently re-exposing rats to reinforcement for lever pressing in a training (A) context, while eliminating lever pressing in a second (B) context, increased ABA renewal of lever pressing relative to rats that experienced only Context B during response elimination. In the current study, we replicated these procedures while assessing renewal in the presence of a novel context (i.e., ABC renewal). Unlike the findings described above, renewal was reduced in the group that experienced re-exposure to Context A during lever-press elimination relative to rats that experienced only Context B. These findings suggest that alternating between contexts associated with reinforcement and extinction during treatment reduces the probability that organisms will respond in novel contexts. These outcomes may be the result of discrimination and/or generalization processes. Moreover, this training procedure may offer a potential mitigation strategy for ABC renewal.
