Urgency Is A Non-Monotonic Function Of Pulse Rate, Frank A. Russo, Jeffery A. Jones
Urgency Is A Non-Monotonic Function Of Pulse Rate, Frank A. Russo, Jeffery A. Jones
Psychology Faculty Publications
Magnitude estimation was used to assess the experience of urgency in pulse-train stimuli (pulsed white noise) ranging from 3.13 to 200 Hz. At low pulse rates, pulses were easily resolved. At high pulse rates, pulses fused together leading to a tonal sensation with a clear pitch level. Urgency ratings followed a nonmonotonic (polynomial) function with local maxima at 17.68 and 200 Hz. The same stimuli were also used in response time and pitch scaling experiments. Response times were negatively correlated with urgency ratings. Pitch scaling results indicated that urgency of pulse trains is mediated by the perceptual constructs of speed …
Speech Disruption During Delayed Auditory Feedback With Simultaneous Visual Feedback, Jeffery A. Jones, Danielle Streimer
Speech Disruption During Delayed Auditory Feedback With Simultaneous Visual Feedback, Jeffery A. Jones, Danielle Streimer
Psychology Faculty Publications
Delayed auditory feedback (DAF) regarding speech can cause dysfluency. The purpose of this study was to explore whether providing visual feedback in addition to DAF would ameliorate speech disruption. Speakers repeated sentences and heard their auditory feedback delayed with and without simultaneous visual feedback. DAF led to increased sentence durations and an increased number of speech disruptions. Although visual feedback did not reduce DAF effects on duration, a promising but nonsignificant trend was observed for fewer speech disruptions when visual feedback was provided. This trend was significant in speakers who were overall less affected by DAF. The results suggest the …
Particularisation Of Child Abuse Offences: Common Problems When Questioning Child Witnesses, Martine B. Powell, Kim P. Roberts, Belinda Guadagno
Particularisation Of Child Abuse Offences: Common Problems When Questioning Child Witnesses, Martine B. Powell, Kim P. Roberts, Belinda Guadagno
Psychology Faculty Publications
Prosecuting child abusers is often difficult due to lack of particularising details. Two possible ways of addressing this difficulty are: (a) to change the justice system to better serve prosecution for repeated offences (i.e., allow generic testimony), and (b) to bolster children's testimony. As this article has illustrated, there is still considerable potential for increasing (b). Given the low prosecution rates of child abuse offences, the need for exceptional interviewer training programs coupled with resources for ongoing supervision is now critical. While there have been some major improvements in child witness investigative interviews over the past two decades, there are …
Strengthening Ontario's System Of Housing For People With Serious Mental Illness, John Sylvestre, Lindsey George, Tim Aubry, Janet Durbin, Geoffrey Nelson, John Trainor
Strengthening Ontario's System Of Housing For People With Serious Mental Illness, John Sylvestre, Lindsey George, Tim Aubry, Janet Durbin, Geoffrey Nelson, John Trainor
Psychology Faculty Publications
This article describes recent work to support recommendations for improving Ontario’s system of housing for people with serious mental illness. This multifaceted project engaged stakeholders in discussions concerning strategies for improving the system based on (a) values that underlie housing programs, (b) evidence of effective housing practices, (c) the current status of the system, and (d) international practices for monitoring community mental health systems. Stakeholders reviewed summaries of the work and discussed implications for improving the provincial system of housing and supports. Recommendations are made for improving the system, focusing on both regional and provincial level actions.

Les 25 Ans De La Revue Canadienne De Santé Mental Communautaire: Observations Et Perspectives, Geoffrey Nelson
Psychology Faculty Publications
En tant qu’ancien rédacteur de la Revue canadienne de santé mentale communautaire (RCSMC), membre de longue date de son comité de rédaction et collaborateur régulier, j’ai accepté avec plaisir de commenter l’analyse de contenu de la RCSMC faite par Fortin-Pellerin, Pouliot-Lapointe, Thibodeau et Gagné. Je tiens d’abord à préciser que je ne prétends pas ici faire un compte rendu objectif, non seulement à cause de mon profond investissement dans la Revue, mais aussi à cause de ma partialité, de mes valeurs et de ma position privilégiée, tant personnelles que professionnelles, qui m’empêchent d’être totalement objectif. Je peux toutefois offrir, en …

25 Years Of The Canadian Journal Of Community Mental Health: Reflections And Future Directions, Geoffrey Nelson
Psychology Faculty Publications
As a former senior editor, a long-term member of the editorial board, and a regular contributor to the Canadian Journal of Community Mental Health (CJCMH), I am delighted with the invitation to comment on the 25-year review of the contents of CJCMH by Fortin-Pellerin, Pouliot-Lapointe, Thibodeau, and Gagné. I want to begin by acknowledging that I cannot pretend to give an objective account of CJCMH, not only because of my deep investment in it, but also because of my personal and professional biases, values, and position of privilege. What I can offer are some reflections on CJCMH, as well as …
The Impact Of Experienced Versus Non-Experienced Suggestions On Children’S Recall Of Repeated Events, Martine B. Powell, Kim Roberts, Donald M. Thomson, Stephen J. Ceci
The Impact Of Experienced Versus Non-Experienced Suggestions On Children’S Recall Of Repeated Events, Martine B. Powell, Kim Roberts, Donald M. Thomson, Stephen J. Ceci
Psychology Faculty Publications
Three experiments were conducted to test the proposition that children’s suggestibility about an occurrence of a repeated event is heightened when an interviewer suggests false details that were experienced in non-target occurrences of the event as opposed to new details that never occurred. In each experiment, children participated in a repeated event during which specific items varied each time (e.g., the children always got a sticker but the theme of the sticker was different in each occurrence). Separate biasing and memory interviews were then conducted. In Experiment 1, the interviewer merely suggested that the false details might have occurred in …
