Comparison of Video Prompting with and Without Voice‐Over Narration: A Replication with Young Children with Autism

We compared the effects of video prompting (VP) with and without voice‐over narration on the play skills of two young children with autism spectrum disorder using an adapted alternating treatment design. The results showed increases in play skills when using VP with and without voice‐over narration for both participants. These results suggest that the difference in effectiveness between VP with and without voice‐over narration may be negligible for some children with autism. Implications for the use of VP without additional teaching strategies and the need for additional component analyses are discussed. Copyright © 2016 John Wiley & Sons, Ltd.     

A Comparison of the Effects of Ethics Training on International and US Students

As scientific and engineering efforts become increasingly global in nature, the need to understand differences in perceptions of research ethics issues across countries and cultures is imperative. However, investigations into the connection between nationality and ethical decision-making in the sciences have largely generated mixed results. In Study 1 of this paper, a measure of biases and compensatory strategies that could influence ethical decisions was administered. Results from this study indicated that graduate students from the United States and international graduate students studying in the US are prone to different biases. Based on these findings, recommendations are made for developing ethics education interventions to target these decision-making biases. In Study 2, we employed an ethics training intervention based on ethical sensemaking and used a well-established measure of ethical decision-making that more fully captures the content of ethical judgment. Similar to Study 1, the results obtained in this study suggest differences do exist between graduate students from the US and international graduate students in ethical decision-making prior to taking the research ethics training. However, similar effects were observed for both groups following the completion of the ethics training intervention.     

Using spatial terms to select an object

Our interactions with the world often involve selecting one object from a cluttered array of objects. One way to accomplish this is with language. For example, spatial terms, such as above, guide selection by specifying the position of one object (the located object) with respect to a second object (the reference object). Most of the work on the apprehension of spatial terms has examined displays that contain only these two objects. In the present paper, we examine how the presence of an extra object (a distractor) in the display impacts apprehension. Consistent effects of distractor presence were obtained across acceptability-rating and speeded sentence/picture verification tasks. Importantly, these effects were independent of the placement of the distractor. These results suggest that the distractor has its influence during processes that spatially index and identify the located and reference objects and that processes involved in computing the spatial term operate only on these objects.     

Stress Management with Law Enforcement Personnel: A Controlled Outcome Study of EMDR Versus a Traditional Stress Management Program

Eye Movement Desensitization and Reprocessing (EMDR) has been shown to be effective for treating posttraumatic stress disorder, but its efficacy as a stress management tool for normal individuals in highly stressful occupations has not been demonstrated. Sixty-two police officers were randomly assigned to either EMDR or a standard stress management program (SMP), each consisting of 6 hours of individualized contact. At completion, officers in the EMDR condition provided lower ratings on measures of PTSD symptoms, subjective distress, job stress, and anger; and higher marital satisfaction ratings than those in SMP. The effects of EMDR were maintained at the 6-month follow-up, indicating enduring gains from a relatively brief treatment regimen for this subclinical sample of officers who were experiencing some level of stress from their job.     

Research on social class and intolerance in the context of American history and ideology

This article examines the trends reported in empirical investigations of the relationship between social class and intolerance over the last three decades in the light of American history and ideology. Two key studies are cited as landmark works: The Authoritarian Personality and Communism, Conformity, and Civil Liberties. The author notes that findings from both works, as well as conclusions drawn from related studies, have been interpreted as supporting an essentially negative view of the lower classes with regard to tolerance of nonconformity. A brief critique of research findings is presented.     

Post-stop-signal slowing: strategies dominate reflexes and implicit learning

Control adjustments are necessary to balance competing cognitive demands. One task that is well-suited to explore control adjustments is the stop-signal paradigm, in which subjects must balance initiation and inhibition. One common adjustment in the stop-signal paradigm is post-stop-signal slowing. Existing models of sequential adjustments in the stop-signal paradigm suggest that post-stop-signal slowing may be based solely on the events of the previous trial, suggesting that post-stop-signal slowing is a reflexive byproduct of a stop signal. Alternatively, post-stop-signal slowing could be the result of implicit learning or strategic adjustment. The authors report three experiments that manipulated the probability of stop trial repetition and found that these contingencies eliminate, reverse, or greatly increase post-stop-signal slowing. When the contingency was not instructed or cued, modest adjustments of post-stop-signal slowing occurred, suggesting implicit learning. When the contingency was cued, performance adjustments occurred on the next trial, suggesting that strategies dominated post-stop-signal slowing. These results show that post-stop-signal slowing is not a reflexive byproduct of the stop signal. The large changes in strategy accompany large changes in task factors, suggesting that the modest post-stop-signal slowing usually observed may be a result of the relatively static task environment that does not encourage large strategic changes.     

Post-stop-signal adjustments: inhibition improves subsequent inhibition

Performance in the stop-signal paradigm involves a balance between going and stopping, and one way that this balance is struck is through shifting priority away from the go task, slowing responses after a stop signal, and improving the probability of inhibition. In 6 experiments, the authors tested whether there is a corresponding shift in priority toward the stop task, speeding reaction time to the stop signal. Consistent with this hypothesis, stop-signal reaction time (SSRT) decreased on the trial immediately following a stop signal in each experiment. Experiments 2-4 used 2 very different stop signals within a modality, and stopping improved when the stop stimulus repeated and alternated. Experiments 5 and 6 presented stop signals in different modalities and showed that SSRT improved only when the stop stimulus repeated within a modality. These results demonstrate within-modality post-stop-signal speeding of response inhibition.
