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

Psychology Faculty Publications

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

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 …

The Role Of Executive Function In Children's Source Monitoring With Varying Retrieval Strategies, Kim P. Roberts, Becky Earhart

Psychology Faculty Publications

Previous research on the relationship between executive function and source monitoring in young children has been inconclusive, with studies finding conflicting results about whether working memory and inhibitory control are related to source-monitoring ability. In this study, the role of working memory and inhibitory control in recognition memory and source monitoring with two different retrieval strategies were examined. Children (N = 263) aged 4–8 participated in science activities with two sources. They were later given a recognition and source-monitoring test, and completed measures of working memory and inhibitory control. During the source-monitoring test, half of the participants were asked …

Tms-Induced Neural Noise In Sensory Cortex Interferes With Short-Term Memory Storage In Prefrontal Cortex, Tyler D. Bancroft, Jeremy Hogeveen, William E. Hockley, Philip Servos

Psychology Faculty Publications

In a previous study, Harris et al. (2002) found disruption of vibrotactile short-term memory after applying single-pulse transcranial magnetic stimulation (TMS) to primary somatosensory cortex (SI) early in the maintenance period, and suggested that this demonstrated a role for SI in vibrotactile memory storage. While such a role is compatible with recent suggestions that sensory cortex is the storage substrate for working memory, it stands in contrast to a relatively large body of evidence from human EEG and single-cell recording in primates that instead points to prefrontal cortex as the storage substrate for vibrotactile memory. In the present study, we …

-Heroines’ Journey- Emerging Story By Refugee Women During Group Analytic Music Therapy, Heidi Ahonen, Antoinetta Mongillo Desideri

Music Faculty Publications

There has been some evidence of the benefits of participating in group analytic music therapy with traumatized people. This pilot clinical project investigates the impact of a combination of narrative therapy and group analytic music therapy on refugee/newcomer women in Canada. An ongoing therapy group met for a period of 8 sessions, to share stories and feelings of past experiences and of resettlement. The focus of this group was emotional expression (verbal and musical). Musical listening, improvisation, art, writing, clay-work, and relaxation techniques were used. Several consistent themes re-emerged, including feelings around loneliness, fear guilt, and loss.

Condoms And Contradictions: Assessing Sexual Health Knowledge In Lesbian, Gay, Bisexual, Trans, And Queer Youth Labelled With Intellectual Disabilities, Ciann L. Wilson

Psychology Faculty Publications

Background: Accessible, culturally relevant data collection tools to assess the sexual health knowledge of lesbian, gay, bisexual, trans, queer and questioning (LGBTQ) young people labelled with intellectual disabilities are sparse.

Materials and Methods: Using community-based participatory research (CBPR) we piloted a variety of interactive activities designed to assess the sexual health knowledge and decision making skills of LGBTQ young people with intellectual disabilities.

Results: Posters created by youth participants suggested substantial sexual health knowledge and empowerment, while individual knowledge assessment scores indicated a range in understanding of risks and strategies to avoid pregnancy, HIV and herpes.

Conclusions: These findings reinforce …

The Relationship Between Collective Action And Well-Being And Its Moderators: Pervasiveness Of Discrimination And Dimensions Of Action, Mindi D. Foster

Psychology Faculty Publications

Given the negative impact of perceiving gender discrimination on health (e.g., Pascoe & Smart Richman, 2009), there is a need to develop interventions to attenuate this effect; collective action may be one such intervention. Study 1 (N = 185) used an experimental paradigm to investigate whether undergraduate women in Waterloo, Ontario, Canada perceived pervasiveness of discrimination would interact with their collective action-taking to predict negative mood and well-being. Results showed that among those perceiving pervasive gender discrimination, informing friends/family and informing the media led to greater well-being than doing nothing, whereas among those perceiving gender discrimination as isolated, doing nothing …

Subjective And Non-Subjective Information In Children’S Allegations Of Abuse, Jennifer E. Newman, Kim P. Roberts

Psychology Faculty Publications

In this study, we were interested in how interviewers elicit subjective information in investigations of child abuse (e.g., descriptions of thoughts, emotions, opinions). Sixty-one interviews of children aged 4-12 years old were analyzed to determine the amount of subjective information versus non-subjective event details reported, and the type of question that elicited the information. Interviewers elicited more non-subjective than subjective information, although there was more focus on subjective information in the rapport-building phase than in the substantive phase when the allegations were elicited. Interviewer prompts and child responsiveness was congruent such that non-subjective questions elicited more non-subjective information, and subjective …

Recommendations For Interviewing Children About Repeated Experiences, Martine B. Powell, Sonja P. Brubacher, Kim P. Roberts

Psychology Faculty Publications

For just over two decades, researchers have been conducting empirical studies devoted to understanding children’s memory for, and ability to describe, individual occurrences of events they have experienced repeatedly. This knowledge is critical because children making allegations of repeated abuse are required to provide details particular to an individual incident in many jurisdictions internationally. Based on this theoretical foundation, we provide specific suggestions to practitioners to assist children in reporting as much information as possible about individual occurrences and techniques that may assist them in doing so accurately. These recommendations cover both presubstantive (i.e., “practice”) and substantive phases of the …

Children’S Use Of A ‘Time Line’ To Indicate When Events Occurred, Leanne L. Gosse, Kim P. Roberts

Psychology Faculty Publications

Children who allege abuse are often asked to provide temporal information such as when the events occurred. Yet, young children often have difficulty recalling temporal information due to their limited knowledge of temporal patterns and linguistic capabilities. As time is an abstract concept (we cannot see it), some investigators have begun to use ‘time-lines’ or pictorial representations of time to aid children. Yet, there is no published research testing whether children are able to use time-lines and whether they can provide adequate temporal information using them. We tested whether children could indicate the time-of-day of events using a pictorial time-line …

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 …

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 …

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 …

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 …

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 …

Retrieval Of Episodic Versus Generic Information: Does The Order Of Recall Affect The Amount And Accuracy Of Details Reported By Children About Repeated Events?, Sonja P. Brubacher, Kim P. Roberts, Martine B. Powell

Psychology Faculty Publications

Children (N = 157) 4- to 8-years old participated 1 (single) or 4 times (repeated) in an interactive event. Across each condition, half were questioned a week later about the only or a specific occurrence of the event (Depth-first), and then about what usually happens. Half were prompted in the reverse order (Breadth-first). Children with repeated experience who first were asked about what usually happens reported more event-related information overall than those asked about an occurrence first. All children used episodic language when describing an occurrence; however children with repeated-event experience used episodic language less …

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 …

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 …

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 …

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 …

The Use Of Paraphrasing In Investigative Interviews, Angela Evans, Kim P. Roberts, Heather L. Price, Candyce P. Stefek

Psychology Faculty Publications

Objective

Young children’s descriptions of maltreatment are often sparse thus creating the need for techniques that elicit lengthier accounts. One technique that can be used by interviewers in an attempt to increase children’s reports is ‘paraphrasing’, or repeating information children have disclosed. Although we currently have a general understanding of how paraphrasing may influence children’s reports, we do not have a clear description of how paraphrasing is actually used in the field.

Method

The present study assessed the use of paraphrasing in 125 interviews of children aged 4 to 16 years conducted by police officers and social workers. All interviewer …
