Reducing skin picking via competing activities

This study examined the outcomes of a competing activities intervention to decrease skin picking exhibited by a 9-year-old student with comorbid diagnoses. Results of an ABCBAB design revealed that the use of student-selected manipulatives resulted in reduced skin picking.     

Behavioral consequences of radiation exposure to simulated space radiation in the C57BL/6 mouse: open field,rotorod, and acoustic startle

Two experiments were carried out to investigate the consequences of exposure to proton radiation, such as might occur for astronauts during space flight. C57BL/6 mice were exposed, either with or without 15-g/cm2 aluminum shielding, to 0-, 3-, or 4-Gy proton irradiation mimicking features of a solar particle event. Irradiation produced transient direct deficits in open-field exploratory behavior and acoustic startle habituation. Rotorod performance at 18 rpm was impaired by exposure to proton radiation and was impaired at 26 rpm, but only for mice irradiated with shielding and at the 4-Gy dose. Long-term (>2 weeks) indirect deficits in open-field activity appeared as a result of impaired experiential encoding immediately following exposure. A 2-week recovery prior to testing decreased most of the direct effects of exposure, with only rotorod performance at 26 rpm being impaired. These results suggest that the performance deficits may have been mediated by radiation damage to hippocampal, cerebellar, and possibly, forebrain dopaminergic function.     

Automatic activation of phonology in silent reading is parallel: evidence from beginning and skilled readers

The picture-word interference paradigm was used to shed new light on the debate concerning slow serial versus fast parallel activation of phonology in silent reading. Prereaders, beginning readers (Grades 1-4), and adults named pictures that had words printed on them. Words and pictures shared phonology either at the beginnings of words (e.g., DOLL-DOG) or at the ends of words (e.g., FOG-DOG). The results showed that phonological overlap between primes and targets facilitated picture naming. This facilitatory effect was present even in beginning readers. More important, from Grade 1 onward, end-related facilitation always was as strong as beginning-related facilitation. This result suggests that, from the beginning of reading, the implicit and automatic activation of phonological codes during silent reading is not serial but rather parallel.     

Young adolescents’ emotional and regulatory responses to positive life events: Investigating temperament,attachment, and event characteristics

Very little is known about what factors predict variations in responses to positive events among youth. Consequently, we examined young adolescents’ positive emotional reactions and their savoring and dampening responses to their most intense positive event across a four-day period. The investigated predictors were parent-reported adolescent temperament, adolescent-reported attachment security with mothers and fathers, and researcher-coded event characteristics. The sample was 56 youth (31 boys, 10–14 years of age). More support was found for temperament than attachment. Specifically, effortful control predicted more savoring and sustained positive affect (PA) about the events, whereas negative emotionality predicted more dampening. Adolescents’ reports of more secure attachment to fathers were marginally linked to more savoring of their positive event. Girls reported higher levels of initial PA yet endorsed more dampening responses than boys. Event type (interpersonal vs. not) was unrelated to responses to the events. Overall, this study offers new information on the development of PA regulation and responses to positive events in youth.     

The Pain of Endo Existence: Toward a Feminist Disability Studies Reading of Endometriosis

Disability scholars have critiqued medical models that pathologize disability as an individual flaw that needs treatment, rehabilitation, and cure, favoring instead a social‐constructionist approach that likens disability to other identity categories such as gender, race, class, and sexuality. However, the emphasis on social constructionism has left chronic illness and pain largely untheorized. This article argues that feminist disability studies (FDS) must attend to the common, chronic gynecological condition endometriosis (endo) when theorizing pain. Endo is particularly important for FDS analysis because the highly feminized and sexualized nature of endo pain is a major source of disability. Because medical treatments of endo enhance fertility rather than provide pain relief, those with endo must not only have access to medical services to manage their pain, but also demand better medical management of their pain as well as disability accommodations for their pain. Thus, I propose a pain‐centric model of disability that politicizes pain through social‐constructionist and medical models of disability by attending to the lived experiences of pain.

Generalized instruction following with pictorial prompts

The benefits of permanent pictorial prompts in enhancing maintenance and generalization are likely dependent on their degree of stimulus control and the extent to which their use is generalized. Although several studies on the use of pictorial prompts have demonstrated their efficacy (e.g., Pierce & Schreibman, 1994; Wacker & Berg, 1983; Wacker, Berg, Berrie, & Swatta, 1985), there is still some question regarding what ultimately controlled responding. The present study allowed an explicit examination of stimulus control by pictorial prompts. Three 4-year-old children with developmental disabilities were taught to complete 4 instructional sets (5 steps each) using pictorial prompts such that the prompts would control responding. All 3 participants showed generalization to the final set after training with 3 sets. These results suggest that training a single task sequence may not be sufficient for acquisition of generalized pictorial instruction following. However, establishing stimulus control by the pictorial prompts rather than teaching behavioral chains may facilitate acquisition of a generalized repertoire.     

Generalizability of Evidence-Based PTSD Psychotherapies to Suicidal Individuals: A Review of the Veterans Administration and Department of Defense Clinical Practice Guidelines

Posttraumatic stress disorder (PTSD) is strongly associated with suicide. The 2010 Department of Veterans Affairs/Department of Defense Clinical Practice Guidelines for PTSD (VA/DoD CPG) endorse cognitive therapy and its variants as empirically supported PTSD treatments. However, we lack an understanding about whether these treatments are generalizable to patients with suicidal ideation and/or behaviors. Randomized controlled trials (RCTs) cited in the VA/DoD CPGs were systematically reviewed for methodology, suicide-related content, and adverse event reporting. Thirty-eight RCTs were reviewed. Twenty-three reported suicide-related exclusion criteria, 15 made no mention of suicide-related inclusion/exclusion criteria. Thirty-six RCTs included depression assessments containing suicide-related items, but no suicide-relevant data were reported. Two RCTs outlined suicide risk monitoring procedures. Suicidal PTSD participants are underrepresented in PTSD RCTs and suicide risk assessment procedures were inconsistently reported. Standardized reporting of RCT methods pertaining to suicide risk to determine generalizability and safety of empirically supported PTSD treatments to this clinical population is needed.     

Emotional content of true and false memories

Many people believe that emotional memories (including those that arise in therapy) are particularly likely to represent true events because of their emotional content. But is emotional content a reliable indicator of memory accuracy? The current research assessed the emotional content of participants’ pre-existing (true) and manipulated (false) memories for childhood events. False memories for one of three emotional childhood events were planted using a suggestive manipulation and then compared, along several subjective dimensions, with other participants’ true memories. On most emotional dimensions (e.g., how emotional was this event for you?), true and false memories were indistinguishable. On a few measures (e.g., intensity of feelings at the time of the event), true memories were more emotional than false memories in the aggregate, yet true and false memories were equally likely to be rated as uniformly emotional. These results suggest that even substantial emotional content may not reliably indicate memory accuracy.
