(2010). The ESSENCE in Child Psychiatry: Early Symptomatic Syndromes Eliciting Neurodevelopmental Clinical Examinations. Research in Developmental Disabilities: A Multidisciplinary Journal, v31 n6 p1543-1551 Nov-Dec. Co-existence of disorders–including attention-deficit/hyperactivity disorder, oppositional defiant disorder, tic disorder, developmental coordination disorder, and autism spectrum disorder–and sharing of symptoms across disorders (sometimes referred to as comorbidity) is the rule rather than the exception in child psychiatry and developmental medicine. The acronym ESSENCE refers to Early Symptomatic Syndromes Eliciting Neurodevelopmental Clinical Examinations. It is a term I have coined to refer to the reality of children (and their parents) presenting in clinical settings with impairing child symptoms before age 3 (-5) years in the fields of (a) general development, (b) communication and language, (c) social inter-relatedness, (d) motor coordination, (e) attention, (f) activity, (g) behaviour, (h) mood, and/or (i) sleep. Children with major difficulties in one or more (usually several) of these fields, will be referred to and seen by health visitors, nurses, social workers,… [Direct]
(2008). The Role of Structural Position in L2 Phonological Acquisition: Evidence from English Learners of Spanish as L2. Foreign Language Annals, v41 n2 p347-363 Sum. In this pilot study, the speech of 12 adult native speakers of English with intermediate to intermediate-high proficiency in Spanish as a second language (L2) was analyzed to determine whether L2 learners rely on distributional information in the process of L2 speech learning and if so, if similar or dissimilar distributional patterns of sounds are more easily acquired. The parameter for (dis)similarity was set around the notion of structural position in combination with native language (L1) and L2 phonemic inventories. The results show that the subjects were consistently more successful in producing the phonemes with overlapping distributional patterns in L1 and L2 than phonemes whose distribution differed in L1 and L2 as well as novel L2 contrasts.

(2010). Mirror Neurons, the Representation of Word meaning, and the Foot of the Third Left Frontal Convolution. Brain and Language, v112 n1 p77-84 Jan. Previous neuroimaging research has attempted to demonstrate a preferential involvement of the human mirror neuron system (MNS) in the comprehension of effector-related action word (verb) meanings. These studies have assumed that Broca's area (or Brodmann's area 44) is the homologue of a monkey premotor area (F5) containing mouth and hand mirror neurons, and that action word meanings are shared with the mirror system due to a proposed link between speech and gestural communication. In an fMRI experiment, we investigated whether Broca's area shows mirror activity solely for effectors implicated in the MNS. Next, we examined the responses of empirically determined mirror areas during a language perception task comprising effector-specific action words, unrelated words and nonwords. We found overlapping activity for observation and execution of actions with all effectors studied, i.e., including the foot, despite there being no evidence of foot mirror neurons in the monkey or human… [Direct]
(2010). Attentional Regulation in Young Twins with Probable Stuttering, High Nonfluency, and Typical Fluency. Journal of Speech, Language, and Hearing Research, v53 n5 p1147-1166 Oct. Purpose: Using a sample of 20,445 Dutch twins, this study examined the relationship between speech fluency and attentional regulation in children. A secondary objective was to identify etiological overlap between nonfluency and poor attention using fluency-discordant twin pairs. Method: Three fluency groups were created at age 5 using a parent questionnaire: (a) probable stuttering (PS; N = 826; 4.0%), highly nonfluent (HNF; N = 547; 2.7%), and typically fluent (TF; N = 19,072; 93%). Multiple scales assessing attention, primarily self-regulation/inhibition, were obtained from both parents when children were ages 5 and 7 and from teachers when children were age 7. Results: When compared with the TF controls, both the PS and HNF children received higher (i.e., more problematic) scores on parental attention ratings at both ages (p less than 0.002). Effect sizes were moderate for both groups. Teacher and parent ratings were generally comparable. The discordant co-twin analyses suggested… [Direct]
(2008). Speech Perception by 6- to 8-Month-Olds in the Presence of Distracting Sounds. Infancy, v13 n5 p421-439 Sep. The role of selective attention in infant phonetic perception was examined using a distraction masker paradigm. We compared perception of /bu/ versus /gu/ in 6- to 8-month-olds using a visual fixation procedure. Infants were habituated to multiple natural productions of 1 syllable type and then presented 4 test trials (old-new-old-new). Perception of the new syllable (indexed as novelty preference) was compared across 3 groups: habituated and tested on syllables in quiet (Group 1), habituated and tested on syllables mixed with a nonspeech signal (Group 2), and habituated with syllables mixed with a non-speech signal and tested on syllables in quiet (Group 3). In Groups 2 and 3, each syllable was mixed with a segment spliced from a recording of bird and cricket songs. This nonspeech signal has no overlapping frequencies with the syllable; it is not expected to alter the sensory structure or perceptual coherence of the syllable. Perception was negatively affected by the presence of the… [Direct]
(2010). A Model of Mandarin Tone Categories–A Study of Perception and Production. ProQuest LLC, Ph.D. Dissertation, The University of Iowa. The current study lays the groundwork for a model of Mandarin tones based on both native speakers' and non-native speakers' perception and production. It demonstrates that there is variability in non-native speakers' tone productions and that there are differences in the perceptual boundaries in native speakers and non-native speakers. There are four experiments in this study. Experiment 1 utilizes native speakers' production data from a published speech database to explore the features of tone production by native speakers. Inter-speaker normalization is used to analyze the data. Experiment 2 synthesizes 81 tones that are carried by four sentences to measure perception by native and non-native speakers. The intra-speaker and inter-speaker normalization is used to investigate the perceptual space of T1, T2, T3, and T4. The researcher also explores the salient features distinguish native speakers' and non-native speakers' perception of the four principal tones. Experiment 3 uses… [Direct]
(2009). Response to Intervention: Implications for Early Childhood Professionals. Language, Speech, and Hearing Services in Schools, v40 n4 p424-434 Oct. Purpose: The purpose of this article is to discuss the importance of building strong early childhood communities of interdisciplinary practice in the application of a comprehensive curriculum framework. A curriculum framework is proposed as a means of applying and extending the principles of response to intervention (RtI) to early childhood education providers working with young children, including speech-language pathologists (SLPs). The article presents information regarding the elements of a curriculum framework and suggestions for practice. Method: Literature related to RtI was reviewed to identify common principles of practice. The resulting principles were then aligned to early childhood education recommended practices in order to illustrate the overlapping beliefs. Rationale and support for a curriculum framework as an early childhood education RtI model was then gathered to identify appropriate practices for working with young children who are served in a variety of early… [Direct]
(2007). Contribution of Two Sources of Listener Knowledge to Intelligibility of Speakers with Cerebral Palsy. Journal of Speech, Language, and Hearing Research, v50 n5 p1228-1240 Oct. Purpose: This study examined the independent and combined effects of two sources of linguistic knowledge (alphabet cues and semantic predictability) on the intelligibility of speakers with dysarthria. The study also examined the extent to which each source of knowledge accounted for variability in intelligibility gains. Method: Eight speakers with cerebral palsy and dysarthria contributed speech samples, and 128 listeners transcribed the speech samples (16 listeners per speaker) in 4 different conditions (no cues and unpredictable sentences; no cues and predictable sentences; alphabet cues and unpredictable sentences; alphabet cues and predictable sentences). Listener transcription results were the dependent variable and were scored as the percentage of words identified correctly by listeners. Results: Both alphabet cues and semantic predictability made independent and overlapping contributions to intelligibility. In addition, alphabet cues accounted for more of the variability in… [Direct]

(1990). The Bulge: A Theory of Speech Behavior and Social Distance. Penn Working Papers in Educational Linguistics, v2 n1 p55-83. A discussion of speech behavior and social distance outlines the major ways in which the study of rules of speaking can provide insights into the norms and values of a speech community. It shows ways in which the same material can provide information about the interaction process and the situations in which interlocutors negotiate their relationships with one another, and then advances a theory concerning patterns of interaction within a general middle class American speech community. Speech behavior is shown to be a reflection of cultural values, and various examples of compliments and apologies in American English illustrate the concept. Speech behavior is also related to the negotiation of rules. The \bulge\ theory is proposed based on the way the frequencies of certain types of speech behavior plot out on a diagram, with the two extremes showing similar patterns as opposed to the middle section, which displays a characteristic bulge. That is, there is a qualitative difference…
(1986). Turn and Control in Puerto Rican Spanish Conversation. An investigation of Puerto Rican Spanish conversational strategies involved analysis of recorded conversations for the amount of simultaneous speech, its context, and the turn-taking used. Overlapping and interruption were distinguished from cooperative (supportive) simultaneity of speech, and a \turn\ was defined as a recognized utterance. The primary finding was a high degree of simultaneous speech, with over 90 percent of turns having some form of overlap or interruption. The conversational characteristics revealed in this analysis were compared to the characteristics of separate English and Spanish conversations between Spanish-English bilinguals, in which more simultaneous speech was found during the Spanish conversations. The contrast in conversational strategies underlines the different cultural perceptions of simultaneous speech as polite or impolite, and it suggests a need for a definition of \turn\ that accommodates simultaneous speech differently and a need for further… [PDF]
(1977). Black Dialect: Myth and Reality. Based on transcribed conversations with black children in kindergarten and the intermediate grades, a study was devised to determine whether black urban children from lower socioeconomic areas speak a systematic, consistent form of nonstandard English, and if so, to provide a syntactical analysis of the dialect of nonstandard speakers. Speech samples from five groups of black children (kindergarten children, low achieving readers, better achieving readers, lower socioeconomic children, and higher socioeconomic children) were coded and tabulated according to the frequency and relative percentage of use of seven standard and eight nonstandard speech characteristics. No support was found for the notion that black nonstandard English was used consistently or that it provided a separate dialect. There was considerable overlapping in the use of both standard and nonstandard speech in the groups, and standard usage was dominant. (A transcribed and coded speech sample and the guide for…
(2006). Cross-Modal Reorganization and Speech Perception in Cochlear Implant Users. Brain, v129 n12 p3376-3383 Dec. Recent work suggests that once the auditory cortex of deaf persons has been reorganized by cross-modal plasticity, it can no longer respond to signals from a cochlear implant (CI) installed subsequently. To further examine this issue, we compared the evoked potentials involved in the processing of visual stimuli between CI users and hearing controls. The stimuli were concentric circles replaced by a different overlapping shape, inducing a shape transformation, known to activate the ventral visual pathway in human adults. All CI users had their device implanted for greater than 1 year, but obtained different levels of auditory performance following training to establish language comprehension. Seven of the 13 patients showed good capacities for speech recognition with the CI (good performers) while the six others demonstrated poor speech recognition abilities (poor performers). The evoked potentials of all patients showed larger amplitudes, with different distributions of scalp… [Direct]
(2007). Amnesic H.M. Exhibits Parallel Deficits and Sparing in Language and Memory: Systems versus Binding Theory Accounts. Language and Cognitive Processes, v22 n3 p377-452 Apr. This study examines sentence-level language abilities of amnesic H.M. to test competing theoretical conceptions of relations between language and memory. We present 11 new sources of experimental evidence indicating deficits in H.M's comprehension and production of non-cliche sentences. Contrary to recent claims that H.M.'s comprehension is unimpaired at grammatical levels, H.M. performed 2-6 standard deviations worse than controls matched for age, IQ and education in seven tasks: detecting grammatical errors, repairing sentences identified as containing an error, answering questions about who did what to whom in sentences, multiple-choice recognition of possible versus impossible interpretations of sentences containing ambiguities and figurative speech, discrimination between grammatical versus ungrammatical sentences, and describing the meanings of ambiguous sentences, phrases, and words. However, H.M.'s deficits were selective, e.g., sparing comprehension of familiar but not… [Direct]
(1980). From Reading to Writing Acts. An approach to the teaching of writing to English as a Second Language (ESL) students at Queen's College (City University of New York) is described. Starting from the observation of the learners' difficulties as well as their other learning activities, especially reading, a methodology is proposed based on the training already in progress in reading comprehension and speech acts. Examples are given of the categories that are used in the methodology and proposed exercises are described. In a final section, a constructive critique of the method is proposed: the incomplete nature of the analysis, a high level of abstraction, and an overlapping among the categories. (Author/AMH)…
