Greater reinforcement rate during training increases spontaneous recovery

Spontaneous recovery occurs when a previously reinforced and recently extinguished response reemerges over the course of time, often at the beginning of a new session of extinction. Spontaneous recovery could underlie instances of treatment relapse that threaten otherwise effective behavioral interventions for problem behavior. In two experiments, we arranged multiple schedules with pigeons and a human child to assess the effects of different training reinforcer rates on spontaneous recovery. In both experiments, responding was both more resistant to extinction and more likely to relapse following training with greater reinforcement rates upon returning to extinction after time off from extinction testing. A quantitative model based on behavioral momentum theory accounted well for the data, which suggests reexposure to the extinction context following time off during extinction resulted in (1) the failure of extinction learning to generalize, and (2) greater generalization of original learning during training. The present model attempts to quantify theories attributing spontaneous recovery to changes in temporal context.

Evidence for the Trait-Impulsivity Etiological Model in a Clinical Sample: Bifactor Structure and Its Relation to Impairment and Environmental Risk

The trait-impulsivity etiological model assumes that a general factor (trait-impulsivity) underlies attention-deficit/hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), and other externalizing disorders. We investigated the plausibility of this assumption by testing the factor structure of ADHD and ODD in a bifactor framework for a clinical sample of 1420 children between 6 and 18 years of age (M = 9.99, SD = 3.34; 85% male). Further, the trait-impulsivity etiological model assumes that ODD emerges only if environmental risk factors are present. Our results support the validity of the trait-impulsivity etiological model, as they confirm that ADHD and ODD share a strong general factor of disruptive behavior (DB) in this clinical sample. Furthermore, unlike the subdimensions of ADHD, we found that the specific ODD factor explained as much true score variance as the general DB factor. This suggests that a common scale of ADHD and ODD may prove to be as important as a separate ODD subscale to assess externalizing problems in school-age children. However, all other subscales of ADHD may not explain sufficient true score variance once the impact of the general DB factor has been taken into consideration. In accordance with the trait-impulsivity model, we also showed that all factors, but predominantly the general factor and specific inattention factor, predicted parent-rated impairment, and that predominantly ODD and impulsivity are predicted by environmental risk factors.     

Counterfactual Discourse in Context

The classic Lewis‐Stalnaker semantics for counterfactuals captures that Sobel sequences are consistent sequences, for example:

• a. If Sophie had gone to the parade, she would have seen Pedro dance.
• b. But if Sophie had gone to the parade and been stuck behind someone tall, she would not have seen Pedro dance.

But reverse a sequence like this one and it no longer sounds so good, which is surprising on the classic semantics. This observation motivated Kai von Fintel (2001) and Thony Gillies (2007) to propose dynamic semantic accounts of counterfactual conditionals. Subsequently, Sarah Moss (2012) defended the classic semantics against the charge that it need be abandoned in the face of these order effects, arguing that the infelicity of the reverse sequences is pragmatic. I argue that both accounts are ultimately untenable, but each account has strengths. Seeing what works and what doesn't in each account points the way to the right positive view. With this in mind, I defend a contextualist account of counterfactuals that takes conversational relevance to play a central role.     

The Development and Initial Validation of a Measure of Coaching Behaviors in a Sample of Army Recruits

In this article we outline a model of coaching that is conceptually grounded in workplace and sport coaching literature and present 2 studies conducted to test this model: the extent that coaching behaviors are present in a military training setting, and their association with performance-related outcomes. Following an extensive review of literature and rigorous development and validation procedures the 28-item Military Coaching Behavior Scale was tested. The measure showed good content and predictive validity for 2 dependent variables (satisfaction and resilience). We concluded that the Military Coaching Behavior Scale offers a psychometrically sound, brief, and easy-to-administer measure of high-performance coaching behavior.     

Further evaluation of latency measures in the assessment and treatment of severe self‐injurious behavior

Recent research has demonstrated the utility of latency measures during the functional analysis of problem behavior; however, few studies have evaluated the utility of latency measures during subsequent treatment analyses. The current study seeks to extend the literature on the use of latency measures during the treatment of severe self‐injurious behavior (SIB). Following a latency‐based functional analysis, a treatment analysis was conducted using a hybrid procedure in which baseline sessions were terminated following the first instance of SIB, and test sessions ended after a fixed length of time. Latency to SIB was compared across conditions, whereas latency and rate measures for both SIB and functional communication responses were compared for the functional communication training condition. Results suggest that latency measures may be too sensitive during treatment analyses and that it is beneficial to use a hybrid procedure that allows for both latency and rate comparisons.     

Pick Your Poison: Choice of Activity Determines Mood Management Following a Stressful Task

People routinely seek out activities they believe will relieve stress. There has always been debate regarding the extent to which different activities, particularly those with aggressive content, successfully manage mood or worsen it. It is routinely believed that engaging in highly aggressive activities after becoming stressed worsens mood. However, unlike experiments, in real life people generally select activities that match their interests. In the present study, 105 university students were exposed to an acute stressor then randomized to either (a) a time filler control task; (b) to hit a bobo doll; or (c) given a choice of five different activities, some aggressive, some not. Results indicated that those who were given a choice of activities experienced the greatest reductions in stress and hostility. Furthermore, evidence did not suggest that more aggressive activities made participants more hostile, stressed, or aggressive.
