Objective: To predict prodromal psychosis in adolescents with velocardiofacial syndrome (VCFS). Method: 70 youth with VCFS, 27 siblings of youth with VCFS and 25 community controls were followed from childhood (Mean age = 11.8 years) into mid-adolescence (mean age 15.0 years). Psychological tests measuring intelligence, academic achievement, learning/memory, attention and executive functioning as well as measures of parent and clinician ratings of child psychiatric functioning were completed at both time point. Results: Major depressive disorder, oppositional defiant disorder, and generalized anxiety disorder diagnoses increased in the VCFS sample. With very low false positive rates, the best predictor of adolescent prodromal …
Is It Abuse? Deaf Female Undergraduates' Labeling Of Partner Violence, Melissa Anderson, Caroline Kobek Pezzarossi
Is It Abuse? Deaf Female Undergraduates' Labeling Of Partner Violence, Melissa Anderson, Caroline Kobek Pezzarossi
Melissa L. Anderson
The current study investigated the labeling of abuse experiences in a sample of 97 Deaf female undergraduate students, exploring the following questions: What is the prevalence of violent behaviors experienced by Deaf female undergraduates in their past-year relationships, what proportion of these relationships are identified as "abuse," and what scripts and strategies do Deaf female undergraduates utilize to label their experiences of partner violence? Results indicated that over half of the sample chose not to label past-year experiences of psychological aggression, physical assault, and sexual coercion as abuse, even when these experiences included severe violence. Implications for the Deaf education …
Intimate Partner Violence Against Deaf Female College Students, Melissa Anderson, Irene Leigh
Intimate Partner Violence Against Deaf Female College Students, Melissa Anderson, Irene Leigh
Melissa L. Anderson
It has been estimated that roughly 25% of all Deaf women in the United States are victims of intimate partner violence (Abused Deaf Women's Advocacy Services [ADWAS]), a figure similar to annual prevalence rates of 16% to 30% for intimate partners in the general population. One goal of the present study was to ascertain the prevalence of intimate partner violence victimization in a sample of Deaf female college students. When comparing the prevalence of physical assault, psychological aggression, and sexual coercion victimization to hearing female undergraduates, the current sample was approximately two times as likely to have experienced victimization in …

Black Deaf Individuals' Reading Skills: Influence Of Asl, Culture, Family Characteristics, Reading Experience, And Education, Candace Myers, M. Diane Clark, Millicent Musyoka, Melissa Anderson, Gizelle Gilbert, Selina Agyen, Peter Hauser
Melissa L. Anderson
Previous research on the reading abilities of Deaf individuals from various cultural groups suggests that Black Deaf and Hispanic Deaf individuals lag behind their White Deaf peers. The present study compared the reading skills of Black Deaf and White Deaf individuals, investigating the influence of American Sign Language (ASL), culture, family characteristics, reading experience, and education. (The descriptor Black is used throughout the present article, as Black Deaf individuals prefer this term to African American. For purposes of parallel construction, the term White is used instead of European American.) It was found that Black Deaf study participants scored lower on …

Violence Against Deaf Women: Effect Of Partner Hearing Status, Melissa Anderson, Caroline Kobek Pezzarossi
Violence Against Deaf Women: Effect Of Partner Hearing Status, Melissa Anderson, Caroline Kobek Pezzarossi
Melissa L. Anderson
Using a sample of Deaf female undergraduate students, the current study sought to investigate the prevalence, correlates, and characteristics of intimate partner violence victimization in hearing-Deaf and Deaf-Deaf relationships. Initial results suggest that similarities in hearing status and communication preference are associated with increased levels of negotiation within these relationships. However, compatibility in these areas did not co-occur with significant decreases in physical, psychological, or sexual partner violence. Recommendations for future research as well as implications for clinical and educational practice are outlined.
Individual Characteristics And Their Effect On Predicting Mu Rhythm Modulation, Adriane Randolph, Melody Jackson, Saurav Karmakar
Individual Characteristics And Their Effect On Predicting Mu Rhythm Modulation, Adriane Randolph, Melody Jackson, Saurav Karmakar
Adriane B. Randolph
Brain-computer interfaces (BCIs) offer users with severe motor disabilities a nonmuscular input channel for communication and control but require that users achieve a level of literacy and be able to harness their appropriate electrophysiological responses for effective use of the interface. There is currently no formalized process for determining a user's aptitude for control of various BCIs without testing on an actual system. This study presents how basic information captured about users may be used to predict modulation of mu rhythms, electrical variations in the motor cortex region of the brain that may be used for control of a BCI. …

This study explores the effects of hearing status and bite blocks on vowel production. Normal-hearing controls and postlingually deaf adults read elicitation lists of /hVd/ syllables with and without bite blocks and auditory feedback. Deaf participants' auditory feedback was provided by a cochlear prosthesis and interrupted by switching off their implant microphones. Recording sessions were held before prosthesis was provided and one month and one year after. Long-term absence of auditory feedback was associated with heightened dispersion of vowel tokens, which was inflated further by inserting bite blocks. The restoration of some hearing with prosthesis reduced dispersion. Deaf speakers' vowel …

The relation between auditory acuity, somatosensory acuity and the magnitude of produced sibilant contrast was investigated with data from 18 participants. To measure auditory acuity, stimuli from a synthetic sibilant continuum ([s]-[ʃ]) were used in a four-interval, two-alternative forced choice adaptive-staircase discrimination task. To measure somatosensory acuity, small plastic domes with grooves of different spacing were pressed against each participant's tongue tip and the participant was asked to identify one of four possible orientations of the grooves. Sibilant contrast magnitudes were estimated from productions of the words "said," "shed," "sid," and "shid." Multiple linear regression revealed a significant relation indicating …
Effects Of Masking Noise On Vowel And Sibilant Contrasts In Normal-Hearing Speakers And Postlingually Deafened Cochlear Implant Users, Joseph Perkell, Margaret Denny, Harlan Lane, Frank Guenther, Melanie Matthies, Mark Tiede, Jennell Vick, Majid Zandipour, Ellen Burton
Effects Of Masking Noise On Vowel And Sibilant Contrasts In Normal-Hearing Speakers And Postlingually Deafened Cochlear Implant Users, Joseph Perkell, Margaret Denny, Harlan Lane, Frank Guenther, Melanie Matthies, Mark Tiede, Jennell Vick, Majid Zandipour, Ellen Burton
Harlan Lane
The role of auditory feedback in speech production was investigated by examining speakers' phonemic contrasts produced under increases in the noise to signal ratio (N/S). Seven cochlear implant users and seven normal-hearing controls pronounced utterances containing the vowels /i/, /u/, /ε/ and /æ/ and the sibilants /s/ and /ʃ/ while hearing their speech mixed with noise at seven equally spaced levels between their thresholds of detection and discomfort. Speakers' average vowel duration and SPL generally rose with increasing N/S. Average vowel contrast was initially flat or rising; at higher N/S levels, it fell. A contrast increase is interpreted as reflecting …
Note On The Variability Hypothesis In Category Scaling, B. Schneider, H. Lane
Note On The Variability Hypothesis In Category Scaling, B. Schneider, H. Lane
Harlan Lane
The "variability hypothesis" attributes the nonlinear relation between category and magnitude scales to the growth of variability along the psychological continuum. The findings of some earlier research seemed to contradict the hypothesis. Now, an alternative interpretation of these findings is presented.
Speech Deterioration In Postlingually Deafened Adults, Harlan Lane, Jane Webster
Speech Deterioration In Postlingually Deafened Adults, Harlan Lane, Jane Webster
Harlan Lane
Postlingually deafened adults reading the Rainbow Passage differed from hearing-control subjects in producing greater pitch variability and mean pitch on stressed and unstressed vowels, greater fluctuations in pitch within sentences, less correlation of intrinsic pitch with vowel height and slower temporal parameters. When reading the Phonetic Inventory Sentences, they revealed less differentiation of place of articulation in fricative and plosive consonants. The present findings, taken together with those of longitudinal and implant studies, are applied to constraining models of the role of self hearing in the elaboration of speech.
Changes In Voice-Onset Time In Speakers With Cochlear Implants, Harlan Lane, Jane Wozniak, Joseph Perkell
Changes In Voice-Onset Time In Speakers With Cochlear Implants, Harlan Lane, Jane Wozniak, Joseph Perkell
Harlan Lane
Voice-onset time (VOT) and syllable duration were measured for the English plosives in /Cɑd/ (C=consonant) context spoken by four postlingually deafened recipients of multichannel (Ineraid) cochlear implants. Recordings were made of their speech before, and at intervals following, activation of the speech processors of their implants. Three patients reduced mean syllable duration following activation. Using measures of VOT and syllable duration from speakers with normal hearing [Volaitis and Miller, J. Acoust. Soc. Am. 92, 723–735 (1992)] and from the subjects of this study, VOT is shown to vary approximately linearly with syllable duration over the ranges produced here. Therefore, the …

This study investigates the effects of speaking condition and auditory feedback on vowel production by postlingually deafened adults. Thirteen cochlear implant users produced repetitions of nine American English vowels prior to implantation, and at one month and one year after implantation. There were three speaking conditions (clear, normal, and fast), and two feedback conditions after implantation (implant processor turned on and off). Ten normal-hearing controls were also recorded once. Vowel contrasts in the formant space (expressed in mels) were larger in the clear than in the fast condition, both for controls and for implant users at all three time samples. …
