Full-term neonates from 37 pairs of same-sex twins, either small or appropriate for gestational age (SGA/AGA), were observed during the first sleep cycle after feeding to determine if behavioral indices of central nervous system (CNS) functioning were related to risk for the SGA infants. No differences were observed between groups for time spent…

Diminished responses to stimuli defined as habituation can serve as a gating mechanism for repetitive environmental cues with little predictive value and importance. We demonstrate that wild-type animals diminish their responses to electric shock stimuli with properties characteristic of short- and long-term habituation. We used spatially…

This paper presents an integrative perspective on infant development (based on a consideration of developmental data) which focuses on the function of the smile. From the earliest spontaneous smiles of the newborn period to mature smiling and laughter, a central role was revealed for an excitation (tension)-relaxation process in producing smiles.…

This study hypothesizes that negation and finiteness are linked in the development of foreign language acquisition in comparable ways to their development in first language acquisition. By contrasting synchronic intrapersonal variability data with change occurring in the diachronic data about negation, this article shows how adult learners of…

Functional imaging studies of single word production have consistently reported activation of the lateral prefrontal and cingulate cortex. Its contribution has been shown to be sensitive to task demands, which can be manipulated by the degree of response specification. Compared with classical verbal fluency, free word association relies less on…

With recent developments in assessment and syllabus formats in Ireland, the foreign language classroom has changed considerably, especially in the promotion of oral skills at the upper levels. Differences are found in the variety of classroom activities, with the emphasis now on group activities, and in the organization of learning and…

Speech conditions of emission can result in influences on the speaker, leading to dramatic changes in the speaker's speech production. However, most studies performed on the "speaking styles" restrict their observations to very contrasted situations and compare so-called "spontaneous" speech to the "laboratory"…

We studied how category typicality and out-of-category relatedness affect speeded category verification (vote ''yes'' if pictured object is clothing) in typically developing 4- to 14-year-olds and adults. Stimuli were typical and atypical category objects (e.g., pants, glove) and related and unrelated out-of-category objects (e.g., necklace,…

This booklet is a printed edition of a talk given to parents of children at The Aquinas Montessori School (Alexandria, Virginia) in 1966, when the school was newly opened. Later, at the request of parents, the booklet was prepared and used for parent education and information by many other Montessori schools and organizations. The booklet…

The field manual for a series of coordinated studies of the spontaneous acquisition of a second language by adult immigrant workers provides a theoretical and practical framework for the entire project and a source of information about it for other researchers. Chapters 1 and 2 describe the project's objectives and organization. Chapter 3 reviews…

Presented are the results of a project to test and evaluate the Conscious Synthesis of Development (CSD) method for treating stuttering which concentrates on both psychological and physiological aspects of the disorder. The report is organized into the following divisions: definition and psychophysiology of stuttering; historical overview; review…

The accomplishments of the York International Conference on the Teaching and Learning of English held in 1971 are presented as the work of six commissions made up of conference participants. The participants were 100 Americans, 100 Canadians, and 250 British. Commission One addressed itself to English in the secondary school, ages 11-18;…

Service-user groups whose goals include the promotion of self-advocacy for people with an intellectual disability aim, among other things, to encourage service users to identify problems and find solutions. However, service users' contributions to group sessions may not always be full and spontaneous. This presents a dilemma to the facilitator. In…

This thesis provides a comprehensive account of the intonational phonology of Lakota, an indigenous North American language of the Siouan family. Lakota is predominantly a verb final language, characterized by complex verbal morphology. The phonological description of Lakota intonation and prosody presented here is based on acoustic analysis of…

EEG correlates of intellectual functioning in academically handicapped and talented adolescents were investigated. Data from Ertl's Brainwave Analyzer were factor analyzed and used to predict verbal, numerical, reasoning, and spatial abilities and reading and mathematics achievement. Correlational patterns differed by group. Implications for…
