ON TOKEN REINFORCEMENT AND STUTTERING THERAPY: ANOTHER VIEW ON FINDINGS REPORTED BY HOWIE AND WOODS (1982)

Howie and Woods (1982) have provided data that, they claim, indicate that a token reinforcement system is redundant in instating and shaping fluent speech within a stuttering treatment program developed by Ingham and Andrews (1973a, b). However, there were substantial procedural differences between the treatment programs referred to in both studies, as well as methodological weaknesses in Howie and Woods' study. These factors provide ample sources of explanation for Howie and Woods' failure to demonstrate benefits from their token reinforcement system.     

Making Common Sense of Vaccines: An Example of Discussing the Recombinant Attenuated Salmonella Vaccine with the Public

Researchers have iterated that the future of synthetic biology and biotechnology lies in novel consumer applications of crossing biology with engineering. However, if the new biology’s future is to be sustainable, early and serious efforts must be made towards social sustainability. Therefore, the crux of new applications of synthetic biology and biotechnology is public understanding and acceptance. The RASVaccine is a novel recombinant design not found in nature that re-engineers a common bacteria (Salmonella) to produce a strong immune response in humans. Synthesis of the RASVaccine has the potential to improve public health as an inexpensive, non-injectable product. But how can scientists move forward to create a dialogue of creating a ‘common sense’ of this new technology in order to promote social sustainability? This paper delves into public issues raised around these novel technologies and uses the RASVaccine as an example of meeting the public with a common sense of its possibilities and limitations.     

Recipient design in tacit communication

The ability to design tailored messages for specific listeners is an important aspect of human communication. The present study investigates whether a mere belief about an addressee’s identity influences the generation and production of a communicative message in a novel, non-verbal communication task. Participants were made to believe they were playing a game with a child or an adult partner, while a confederate acted as both child and adult partners with matched performance and response times. The participants’ belief influenced their behavior, spending longer when interacting with the presumed child addressee, but only during communicative portions of the game, i.e. using time as a tool to place emphasis on target information. This communicative adaptation attenuated with experience, and it was related to personality traits, namely Empathy and Need for Cognition measures. Overall, these findings indicate that novel nonverbal communicative interactions are selected according to a socio-centric perspective, and they are strongly influenced by participants’ traits.     

Correctional treatment for co-occurring disorders: results of a national survey

The significant expansion of correctional populations in the last decade, coupled with the gradual erosion of community treatment infrastructure and health insurance, have brought greater attention to the needs of offenders who have co-occurring mental health and substance use disorders. Individuals with co-occurring disorders frequently cycle through acute care facilities in the community and increasingly are placed in jails or prisons. Approximately 16% of inmates in correctional facilities have major mental health disorders (Bureau of Justice Statistics, 1999), and a large majority of these inmates have co-occurring substance use disorders. Few studies have examined the effectiveness of correctional treatment for co-occurring disorders, and there is little information available regarding clinical and programmatic approaches used with this population. The current study provides findings from a comprehensive national survey of co-occurring disorder treatment programs in correctional settings. A total of 20 co-occurring disorder treatment programs from 13 state correctional systems were identified and surveyed. Many of the programs featured modified therapeutic communities, but there was significant diversity in the duration of treatment and type of services provided. Several unique structural and clinical modifications to treatment have been developed in these settings. Implementation of co-occurring disorder treatment programs has led to enhanced collaboration with prison health services and community supervision and treatment agencies, and greater use of interdisciplinary staff to provide outreach and case management services. Research is now being conducted to examine outcomes in several of these correctional treatment programs.     

Pronoun resolution and discourse models.

Psychological investigations of pronoun resolution have implicitly assumed that the processes involved automatically provide a unique referent for every pronoun. We challenge this assumption and propose a new framework for studying pronoun resolution. Drawing on advances in discourse representation and global memory modeling, this framework suggests that automatic processes may not always identify a unique referent for a pronoun. In 9 experiments, we demonstrate that, unlike noun anaphors, pronouns sometimes do not produce relative facilitation of their referents in comparison with nonreferents. We argue that research on pronoun resolution must consider the discourse contexts in which pronouns are likely to occur.     

Not so fast: Rethinking the effects of action video games on attentional capacity

Considerable excitement has been generated by recent studies showing that video gaming alters fundamental aspects of attention. We tested the claim that people who frequently play action video games (video game players (VGPs)) have a greater capacity of attention than those who rarely play video games (non‐video game players (NVGPs)). We first attempted to replicate previous findings by comparing VGPs and NVGPs on a flanker compatibility task (Experiment 1). In contrast with previous studies, VGPs did not demonstrate greater intrusion from distractors, calling into question the reliability of previous findings. In Experiment 2, we manipulated the eccentricity of flankers in an Eriksen flanker task to examine the extent to which VGPs and NVGPs processed irrelevant peripheral stimuli. No attentional differences emerged in the conditions tested, with both groups displaying compatibility effects at all eccentricities. Together these results raise doubts that video game playing increases attentional capacity.
