Auditory-Motor Adaptation To Frequency-Altered Auditory Feedback Occurs When Participants Ignore Feedback, Dwayne Nicholas Keough, Colin Hawco, Jeffery A. Jones

Psychology Faculty Publications

Background

Auditory feedback is important for accurate control of voice fundamental frequency (F0). The purpose of this study was to address whether task instructions could influence the compensatory responding and sensorimotor adaptation that has been previously found when participants are presented with a series of frequency-altered feedback (FAF) trials. Trained singers and musically untrained participants (nonsingers) were informed that their auditory feedback would be manipulated in pitch while they sang the target vowel [/ɑ /]. Participants were instructed to either ‘compensate’ for, or ‘ignore’ the changes in auditory feedback. Whole utterance auditory feedback manipulations were either gradually presented …

Dynamics Of Vocalization-Induced Modulation Of Auditory Cortical Activity At Mid-Utterance, Zhaocong Chen, Jeffery A. Jones, Peng Liu, Weifeng Li, Dongfeng Huang, Hanjun Liu

Psychology Faculty Publications

Background: Recent research has addressed the suppression of cortical sensory responses to altered auditory feedback that occurs at utterance onset regarding speech. However, there is reason to assume that the mechanisms underlying sensorimotor processing at mid-utterance are different than those involved in sensorimotor control at utterance onset. The present study attempted to examine the dynamics of event-related potentials (ERPs) to different acoustic versions of auditory feedback at mid-utterance.

Methodology/Principal findings: Subjects produced a vowel sound while hearing their pitch-shifted voice (100 cents), a sum of their vocalization and pure tones, or a sum of their vocalization and white noise at …

The Impact Of The Criminalization Of Hiv Non-Disclosure On The Health And Human Rights Of “Black” Communities, Ciann L. Wilson

Psychology Faculty Publications

The criminalization of HIV non-disclosure has become a hot topic for discussion and debate amongst human rights advocates, HIV/AIDS service providers, and people infected and affected by HIV/AIDS. This paper explores the inherent problems with HIV non-disclosure laws. These laws are ambiguous and pose a serious threat to public health policy and programming by obstructing the fundamental human rights of people infected and affected by HIV/AIDS. Using a human rights framework, this paper explores the impact of non-disclosure laws on the health and rights of African, Caribbean, and Black-Canadian communities and proposes ways to address the shortcomings of HIV non-disclosure …

Gaze, Goals And Growing Up: Effects On Imitative Grasping, Sonja P. Brubacher, Kim P. Roberts, Sukhvinder S. Obhi

Psychology Faculty Publications

Developmental differences in the use of social-attention cues to imitation were examined among children aged 3- and 6-years old (n = 58) and adults (n = 29). In each of 20 trials, participants watched a model grasp two objects simultaneously and move them together. On every trial, the model directed her gaze towards only one of the objects. Some object pairs were related and had a clear functional goal outcome (e.g., flower, vase), while others were functionally unrelated (e.g., cardboard square, ladybug). Owing to attentional effects of eye gaze, it was expected that all participants would more faithfully …

Everyday Confrontation Of Discrimination: The Well-Being Costs And Benefits To Women Over Time., Mindi D. Foster

Psychology Faculty Publications

Taking action against discrimination has positive consequences for well-being (e.g., Cocking & Drury, 2004) but most of this research has focused on collective actions and has used methodologies assessing one point in time. This study therefore used a diary methodology to examine how women’s everyday confrontations of discrimination would affect measures of subjective and psychological well-being, and how these relationships would change over time. In a 28-day online diary study, women indicated their daily experience of discrimination, described their response, and completed measures of well-being. Results showed that at the beginning of the study, using indirect confrontation predicted greater well-being …

How Do Interviewers And Children Discuss Individual Occurrences Of Alleged Repeated Abuse In Forensic Interviews?, Sonja P. Brubacher, Lindsay C. Malloy, Michael E. Lamb, Kim Roberts

Psychology Faculty Publications

Police interviews (n = 97) with 5- to 13-year-olds alleging multiple incidents of sexual abuse were examined to determine how interviewers elicited and children recounted specific instances of abuse. Coders assessed the labels for individual occurrences that arose in interviews, recording who generated them, how they were used, and other devices to aid particularisation such as the use of episodic and generic language. Interviewers used significantly more temporal labels than did children. With age, children were more likely to generate labels themselves, but most children generated at least one label. In 66% of the cases, interviewers ignored or replaced …
