Children’S Episodic And Generic Reports Of Alleged Abuse, Luke Schneider, Heather L. Price, Kim Roberts, Amy M. Hedrick

Psychology Faculty Publications

With the present data, we explored the relations between the language of interviewer questions, children’s reports, and case and child characteristics in forensic interviews. Results clearly indicated that the type of questions posed by interviewers – either probing generic or episodic features of an event – was related to the specificity of information reported by children. Further, interviewers appeared to adjust their questioning strategies based on the frequency of the alleged abuse. Children alleging single instances of abuse were asked more episodic questions than those alleging multiple abuses. In contrast, children alleging multiple incidents of abuse were asked a greater …

Auditory Feedback Control Of Vocal Pitch During Sustained Vocalization: A Cross-Sectional Study Of Adult Aging, Peng Liu, Zhaocong Chen, Jeffery A. Jones, Dongfeng Huang, Hanjun Liu

Psychology Faculty Publications

Background: Auditory feedback has been demonstrated to play an important role in the control of voice fundamental frequency (F₀), but the mechanisms underlying the processing of auditory feedback remain poorly understood. It has been well documented that young adults can use auditory feedback to stabilize their voice F₀ by making compensatory responses to perturbations they hear in their vocal pitch feedback. However, little is known about the effects of aging on the processing of audio-vocal feedback during vocalization.

Methodology/Principal Findings: In the present study, we recruited adults who were between 19 and 75 years of age and …

Mechanisms Of Interference In Vibrotactile Working Memory, Tyler D. Bancroft, Philip Servos, William E. Hockley

Psychology Faculty Publications

In previous studies of interference in vibrotactile working memory, subjects were presented with an interfering distractor stimulus during the delay period between the target and probe stimuli in a delayed match-to-sample task. The accuracy of same/different decisions indicated feature overwriting was the mechanism of interference. However, the distractor was presented late in the delay period, and the distractor may have interfered with the decision-making process, rather than the maintenance of stored information. The present study varies the timing of distractor onset (either early, in the middle, or late in the delay period), and demonstrates both overwriting and non-overwriting forms of …

The Effects Of An Intensive Training And Feedback Program On Investigative Interviews Of Children, Heather L. Price, Kim P. Roberts

Psychology Faculty Publications

In the present study, we assessed the effectiveness of an extensive training and feedback program with investigative interviewers of child victims of alleged abuse and neglect in a large Canadian city. Twelve investigative interviewers participated in a joint training initiative that lasted eight months and involved classroom components and extensive weekly verbal and written feedback. Interviewers were significantly more likely to use open-ended prompts and elicited more information from children with open-ended prompts following training. These differences were especially prominent following a subsequent ‘refresher’ training session. No negative effects of training were observed. Clear evidence was found of the benefits …

The Effect Of Event Repetition On The Production Of Story-Grammar In Children’S Event Narratives, Brooke B. Feltis, Martine B. Powell, Kim P. Roberts

Psychology Faculty Publications

Objective: This study examined the effect of event repetition on the amount and nature of story grammar produced by children when recalling the event.

Method: Children aged 4 years (N = 50) and 7 years (N = 56) participated in either one or six occurrences of a highly similar event where details varied across the occurrences. Half the children in each age and event group recalled the last/single occurrence 5-6 days later and the other half recalling the last/single occurrence after 5-6 weeks (the final and single occurrence was the same). Children’s free recall responses were classified according …

Effects Of Practicing Episodic Versus Scripted Recall On Children’S Subsequent Narratives Of A Repeated Event, Sonja P. Brubacher, Kim P. Roberts, Martine B. Powell

Psychology Faculty Publications

Children (N = 240) aged 5 to 8 participated in 1 or 4 activity sessions involving interactive tasks (e.g., completing a puzzle); children with single-event participation served as a control group. One week after their last/only session, all children were practised in episodic recall of unrelated experiences by asking about either 1) a single-experience event, 2) a specific instance of a repeated event, or 3) scripted recall of a series of events. Children were subsequently interviewed in an open-ended, non-suggestive manner about one of the activity sessions; children with repeated experience were permitted to nominate the session they wanted …

Using Spaced Learning Principles To Translate Knowledge Into Behavior: Evidence From Investigative Interviews Of Alleged Child Abuse Victims, Alexis E. Rischke, Kim P. Roberts, Heather L. Price

Psychology Faculty Publications

The present study assessed the progress of 13 investigative interviewers (child protection workers and police officers) before, during, and after an intensive training program (n = 132 interviews). Training began with a 2-day workshop covering the principles of child development and child-friendly interviewing. Interviewers then submitted interviews on a bi-weekly basis to which they received written and verbal feedback over an 8-month period. A refresher session took place two months into training. Interestingly, improvements were observed only after the refresher session. Interviews conducted post-refresher training contained proportionally more open-ended questions, more child details in response to open-ended questions, and proportionally …

Children’S Ability To Recall Unique Aspects Of One Occurrence Of A Repeated Event, Sonja P. Brubacher, Una Glisic, Kim P. Roberts, Martine B. Powell

Psychology Faculty Publications

Preschool and school-age children’s memory and source monitoring were investigated by questioning them about one occurrence of a repeated lab event (n = 39). Each of the four occurrences had the same structure, but with varying alternatives for the specific activities and items presented. Variable details had a different alternative each time; hi/lo details presented the identical alternative three times and changed once. New details were present in one occurrence only and thus had no alternatives. Children more often confused variable, lo, and new details across occurrences than hi details. The 4- to 5-year-oldchildren were less …

The Role Of Taste And Calories In Access-Induced Excessive Sweets Consumption By The Rat, Adam Celejewski

Theses and Dissertations (Comprehensive)

For individuals diagnosed with Binge Eating Disorder (BED) or Bulimia Nervosa (BN) eating is often manifested in intermittent bouts of gorging, a behaviour that is similar to excessive consumption of rewarding drugs in addiction (American Psychiatric Association, 2000; Corwin & Grigson, 2009; Epstein & Shaham, 2010). Our laboratory has found that sucrose solution intake by rats escalates markedly when provided on Discontinuous Access (DisA; 24h once every 3 or 4 days) schedules but is maintained at lower, stable levels with Continuous Access (ConA; ad lib) schedules (Hewitt & Eikelboom, 2008). Once DisA/ConA consumption differences are established, they persist even …
