Learning To Produce Speech With An Altered Vocal Tract: The Role Of Auditory Feedback, Jeffery A. Jones, Kevin Munhall
Learning To Produce Speech With An Altered Vocal Tract: The Role Of Auditory Feedback, Jeffery A. Jones, Kevin Munhall
Psychology Faculty Publications
Modifying the vocal tract alters a speaker’s previously learned acoustic–articulatory relationship. This study investigated the contribution of auditory feedback to the process of adapting to vocal-tract modifications. Subjects said the word /tɑs/ while wearing a dental prosthesis that extended the length of their maxillary incisor teeth. The prosthesis affected /s/ productions and the subjects were asked to learn to produce ‘‘normal’’ /s/’s. They alternately received normal auditory feedback and noise that masked their natural feedback during productions. Acoustic analysis of the speakers’ /s/ productions showed that the distribution of energy across the spectra moved toward that of normal, unperturbed production …
Sharing Power And Knowledge: Professional And Mental Health Consumer/Survivor Researchers Working Together In A Participatory Action Research Project, Joanna Ochocka, Rich Janzen, Geoffrey Nelson
Sharing Power And Knowledge: Professional And Mental Health Consumer/Survivor Researchers Working Together In A Participatory Action Research Project, Joanna Ochocka, Rich Janzen, Geoffrey Nelson
Psychology Faculty Publications
In this article we document and reflect on the process and outcomes of consumer/survivor researchers' involvement in a community mental health research project. The study used a participatory action research approach that challenges traditional assumptions of how to conduct research. Research roles and relationships were reexamined by both professional and consumer/survivor researchers. Four values were central to the research process: consumer/survivor empowerment, supportive relationships, learning as an ongoing process, and social justice. The benefits of this value-driven approach were seen in terms of positive impacts on the lives of individual researchers and also in the quality of the research itself. …
The Effect Of Repeated Experience On Children’S Suggestibility Across Two Question Types, Martine B. Powell, Kim P. Roberts
The Effect Of Repeated Experience On Children’S Suggestibility Across Two Question Types, Martine B. Powell, Kim P. Roberts
Psychology Faculty Publications
There is a discrepancy in the literature regarding the effect of repeated experience on children’s suggestibility. Some researchers have concluded that repeated experience increases children’s suggestibility for variable details whereas others have reported no detrimental effect. This study demonstrated that the type of question used to test memory (cued-recall vs. yes/no questions) could account for the different reported conclusions. Children aged 5-6 years took part in an event either once or four times. Three or 21 days later, they were given a suggestive interview about the single/final occurrence of the event during which half of the event details were inaccurately …
Children's Ability To Distinguish Between Memories From Multiple Sources: Implications For The Quality And Accuracy Of Eyewitness Statements, Kim P. Roberts
Children's Ability To Distinguish Between Memories From Multiple Sources: Implications For The Quality And Accuracy Of Eyewitness Statements, Kim P. Roberts
Psychology Faculty Publications
Identifying the sources of memories (e.g., who carried out an action, whether an event happened or was suggested, when an instance of a repeated event occurred) is an important skill in providing accurate accounts of events in forensic investigations. Sensitivity to the nature and development of children’s source-monitoring skills can inform interviewing practices. Five perspectives addressing alternate aspects of the development of children’s source monitoring are outlined (source-monitoring theory, fuzzy-trace theory, schema theory, the person-based perspective, and the mental-state reasoning model). Six main areas of empirical research stemming from these theories are then discussed with emphasis on how the findings …
The Effects Of Food Restriction On Wheel Running In Rats, Vanessa M. Lopak
The Effects Of Food Restriction On Wheel Running In Rats, Vanessa M. Lopak
Theses and Dissertations (Comprehensive)
The impact of food restriction and refeeding on wheel running was examined in 3 groups of rats: 55 day old male rats in Experiment 1; 140 day old male rats in Experiment 2; and 180 day old female rats in Experiment 3. After a baseline period of 24 to 40 days wheel experience with ad lib food access half of the animals were food restricted for 16 days by being given a limited amount of food daily to reduce (and maintain) their body weight at 85% of their baseline weight. After food restriction the rats were returned to ad lib …
