Training Of Working Memory Impacts Neural Processing Of Vocal Pitch Regulation, Weifeng Li, Xiangqian Guo, Jeffery A. Jones, Xiyan Huang, Xi Chen, Peng Liu, Shaozhen Chen, Hanjun Liu Nov 2015

Training Of Working Memory Impacts Neural Processing Of Vocal Pitch Regulation, Weifeng Li, Xiangqian Guo, Jeffery A. Jones, Xiyan Huang, Xi Chen, Peng Liu, Shaozhen Chen, Hanjun Liu

Working memory training can improve the performance of tasks that were not trained. Whether auditory-motor integration for voice control can benefit from working memory training, however, remains unclear. The present event-related potential (ERP) study examined the impact of working memory training on the auditory-motor processing of vocal pitch. Trained participants underwent adaptive working memory training using a digit span backwards paradigm, while control participants did not receive any training. Before and after training, both trained and control participants were exposed to frequency-altered auditory feedback while producing vocalizations. After training, trained participants exhibited significantly decreased N1 amplitudes and increased P2 amplitudes …


Transfer Effect Of Speech-Sound Learning On Auditory-Motor Processing Of Perceived Vocal Pitch Errors, Zhaocong Chen, Francis C.K. Wong, Jeffery A. Jones, Weifeng Li, Peng Liu, Xi Chen, Hanjun Liu Aug 2015

Transfer Effect Of Speech-Sound Learning On Auditory-Motor Processing Of Perceived Vocal Pitch Errors, Zhaocong Chen, Francis C.K. Wong, Jeffery A. Jones, Weifeng Li, Peng Liu, Xi Chen, Hanjun Liu

Speech perception and production are intimately linked. There is evidence that speech motor learning results in changes to auditory processing of speech. Whether speech motor control benefits from perceptual learning in speech, however, remains unclear. This event-related potential study investigated whether speech-sound learning can modulate the processing of feedback errors during vocal pitch regulation. Mandarin speakers were trained to perceive five Thai lexical tones while learning to associate pictures with spoken words over 5 days. Before and after training, participants produced sustained vowel sounds while they heard their vocal pitch feedback unexpectedly perturbed. As compared to the pre-training session, the …


Beyond The Colonial Divide: African Diasporic And Indigenous Youth Alliance Building For Hiv Prevention, Ciann L. Wilson Jan 2015

Beyond The Colonial Divide: African Diasporic And Indigenous Youth Alliance Building For Hiv Prevention, Ciann L. Wilson

Psychology Faculty Publications

African diasporic and North American Indigenous communities have both been greatly impacted by the colonization of the Americas. Historic and contemporary relations between these communities have been fraught with complex commonalities, contradictions and conflicts. These communities have remained connected across time and space through their shared and distinct histories of resistance and oppression. Both communities have suffered the embodiment of systemic violence in the form of elevated rates of communicable and chronic diseases such as HIV. This paper examines the decolonizing potential of collaboration between these two communities in their response to HIV. It begins by unpacking the history of …


Tweeting About Sexism: The Well-Being Benefits Of A Social Media Collective Action., Mindi D. Foster Jan 2015

Tweeting About Sexism: The Well-Being Benefits Of A Social Media Collective Action., Mindi D. Foster

Psychology Faculty Publications

Although collective action has psychological benefits in non-gendered contexts (e.g., Drury et al., 2005), the benefits for women taking action against gender discrimination are unclear. This study examined how a popular, yet unexplored potential form of collective action, namely tweeting about sexism, affects women’s well-being. Women read about sexism and were randomly assigned to tweet, or to one of three control groups. Content analyses showed tweets exhibited collective intent and action. Analyses of linguistic markers suggested public tweeters used more cognitive complexity in their language than private tweeters. Profile analyses showed that compared to controls, only public tweeters showed decreasing …


Developmental Differences In The Ability To Provide Temporal Information About Repeated Events, Kim P. Roberts, Sonja P. Brubacher, Donna M. Drohan-Jennings, Una Glisic, Martine B. Powell, William J. Friedman Jan 2015

Children (n = 372) aged 4 - 8 years participated in 1 or 4 occurrences of a similar event and were interviewed 1 week later. Compared to 85% of children who participated once, less than 25% with repeated experience gave the exact number of times they participated, although all knew they participated more than once. Children with repeated experience were asked additional temporal questions and there were clear developmental differences. Older children were more able than younger children to judge relative order and temporal position of the four occurrences. They also demonstrated improved temporal memory for the first and …


Observations From Canadian Practitioners About The Investigation And Prosecution Of Crimes Involving Child And Adult Witnesses, Sean Curtis Cameron, Kim P. Roberts Jan 2015

Observations From Canadian Practitioners About The Investigation And Prosecution Of Crimes Involving Child And Adult Witnesses, Sean Curtis Cameron, Kim P. Roberts

Psychology Faculty Publications

Hundreds of scientific studies on the competencies and limitations of eyewitnesses have been published, but few have sought input from front-line forensic interviewers. In the current study, a research agenda was established with in-depth input from 13 forensic interviewers. Interviewers indicated which techniques they use most often, rated the usefulness of various interview techniques, and disclosed common challenges when interviewing. Although many recommended techniques were used (e.g., the Cognitive Interview and Rapport Building), some techniques shown to be effective in eliciting quality testimony in scientific studies were not always used or considered useful by front-line interviewers (e.g., permission to correct …

This article reviews an evidence-based tool for training child forensic interviewers called the NICHD Protocol, and the relevant research on: children’s memory development; communication; suggestibility; the importance of open-prompts, and challenges associated with interview training. We include international contributions from experienced trainers, practitioners, and scientists, who are already using the Protocol or whose national or regional procedures have been directly influenced by the NICHD Protocol research (Canada, Finland, Israel, Japan, Korea, Norway, Portugal, Scotland, and United States). Throughout the review, these experts comment on: how and when the Protocol was adopted in their country; who uses it; challenges to implementation …
