Development Of A New Experiment Demonstrating Categorical Perception, Kelsey Montzka
Development Of A New Experiment Demonstrating Categorical Perception, Kelsey Montzka
Student Research Initiative
In this project, we have created an online portal containing a multi-faceted demonstration of categorical perception. We utilized the 2I2AFC (two-interval, two alternative forced choice) stimulus presentation method which should elicit more categorical results from students, helping to better demonstrate the phenomenon (Gerrits & Schouten, 2004), and provided different acoustic cues illustrating CP. In addition to illustrations of CP for F2 formant transition, the new online portal is used to illustrate voice onset timing (VOT; the cue that distinguishes between the sounds [b] and [p]), as well as how contextual factors and participants’ linguistic backgrounds affect CP. The contextual factors …
Semantic And Phonological False Memories In Adults' First And Second Language, Amber Victoria Sapp
Semantic And Phonological False Memories In Adults' First And Second Language, Amber Victoria Sapp
Undergraduate Honors Thesis Collection
I explored second language acquisition in adults by examining false memories for semantically and phonologically related word lists in both the participants' first language and second language. I expected less proficient bilinguals who are initially acquiring their second language would make more phonological false memory errors, like children learning their first language. In contrast, I anticipated that more proficient bilinguals would make more semantic false memory errors in the DRM paradigm as the semantic stores for their two languages overlap more fully. Forty-one English-Spanish bilinguals (High Proficiency: n = 17; Low Proficiency: n = 24) completed a false memory task …
Acoustic And Perceptual Measurements Of Prosody Production On The Profiling Elements Of Prosodic Systems In Children By Children With Autism Spectrum Disorders, Joshua John Diehl, Rhea Paul
Acoustic And Perceptual Measurements Of Prosody Production On The Profiling Elements Of Prosodic Systems In Children By Children With Autism Spectrum Disorders, Joshua John Diehl, Rhea Paul
Communication Disorders Faculty Publications
Prosody production atypicalities are a feature of autism spectrum disorders (ASDs), but behavioral measures of performance have failed to provide detail on the properties of these deficits. We used acoustic measures of prosody to compare children with ASDs to age-matched groups with learning disabilities and typically developing peers. Overall, the group with ASD had longer utterance durations on multiple subtests on a test of prosodic abilities, and both the ASD and learning disabilities groups had higher pitch ranges and pitch variance than the typically developing group on one subtest. Acoustic differences were present even when the prosody was used correctly.These …
