What Automated Vocal Analysis Reveals About the Vocal Production and Language Learning Environment of Young Children with Autism

Abstract The study compared the vocal production and language learning environments of 26 young children with autism spectrum disorder (ASD) to 78 typically developing children using measures derived from automated vocal analysis. A digital language processor and audio-processing algorithms measured the amount of adult words to children and the amount of vocalizations they produced during 12-h recording periods in their natural environments. The results indicated significant differences between typically developing children and children with ASD in the characteristics of conversations, the number of conversational turns, and in child vocalizations that correlated with parent measures of various child characteristics. Automated measurement of the language learning environment of young children with ASD reveals important differences from the environments experienced by typically developing children.

Educational Diagnosticians’ Understanding of Phonological Awareness, Phonemic Awareness, and Reading Fluency

This article summarizes the results of a study involving 42 educational diagnosticians from North Texas. The study was conducted to determine diagnosticians’ perceived understanding of early literacy development and their ability to effectively choose and interpret assessments of phonological awareness, phonemic awareness, and reading fluency. The results suggested that the educational diagnosticians who participated in the study were not sufficiently knowledgeable in identifying the numerous components of reading (e.g., phonological awareness, phonemic awareness, and fluency); nor were they prepared to choose appropriate assessment instruments to assess selected components of reading.

They Read, but How Well Do They Understand?

Much of the literature on reading development focuses on measures of early literacy skills (e.g., phonological awareness, phonics, fluency). Elementary educators interested in improving students’ skills in these areas can draw on a wealth of research studies. However, many studies of early literacy skills have not addressed comprehension, obviously an important feature of literacy. The authors used a one-parameter Rasch model to examine the relative difficulty of different multiple-choice reading comprehension items assessing students’ literal, inferential, and evaluative comprehension of fictional narratives. They also examined the difficulty of questions derived from concepts identified by state content standards as important components of reading comprehension, such as character, prediction, and plot sequence. The findings suggest a curvilinear relationship between literal, inferential, and evaluative comprehension, with literal comprehension being the easiest and inferential and evaluative comprehension more challenging. The findings also indicate that assessment objectives differ on the basis of difficulty. Implications of these findings for practice are discussed.

Improved vocabulary production after naming therapy in aphasia: can gains in picture naming generalise to connected speech?

Background: Naming accuracy for nouns and verbs in aphasia can vary across different elicitation contexts, for example, simple picture naming, composite picture description, narratives, and conversation. For some people with aphasia, naming may be more accurate to simple pictures as opposed to naming in spontaneous, connected speech; for others, the opposite pattern may be evident. These differences have, in some instances, been related to word class (for example, noun or verb) as well as aphasia subtype. Given that the aim of picture-naming therapies is to improve word-finding in general, these differences in naming accuracy across contexts may have important implications for the potential functional benefits of picture-naming therapies.

Aims: This study aimed to explore single-word therapy for both nouns and verbs, and to answer the following questions. (1) To what extent does an increase in naming accuracy after picture-naming therapy (for both nouns and verbs) predict accurate naming of the same items in less constrained spontaneous connected speech tasks such as composite picture description and retelling of a narrative? (2) Does the word class targeted in therapy (verb or noun) dictate whether there is ‘carry-over’ of the therapy item to connected speech tasks? (3) Does the speed at which the picture is named after therapy predict whether it will also be used appropriately in connected speech tasks?

Methods & Procedures: Seven participants with aphasia of varying degrees of severity and subtype took part in ten therapy sessions over five weeks. A set of potentially useful items was collected from control participant accounts of the Cookie Theft Picture Description and the Cinderella Story from the Quantitative Production Analysis. Twenty-four of these words (twelve verbs and twelve nouns) were collated for each participant, on the basis that they had failed to name them in either simple picture naming or connected speech tasks (picture-supported narrative and unsupported retelling of a narrative). These were placed in a larger cohort of verb and noun sets for therapy. Post-therapy assessments examined naming accuracy and speed of target items in single-word picture-naming and naming accuracy in connected speech contexts.

Outcomes & Results: There was a step-wise decrement in naming accuracy over the three naming contexts following targeted therapy. Simple pictures elicited the most correct names, followed by picture-supported narratives and lastly unsupported narratives. Picture-naming accuracy significantly predicted naming in the connected speech contexts for the group as a whole. The speed of picture naming after therapy did not predict the extent to which items were named in composite picture description and narrative tasks.

Conclusions & Implications: The findings suggest that gains in naming accuracy obtained through picture-naming therapy may generalize to naming of the same items in more linguistically and cognitively demanding connected speech tasks. Demonstrating this generalization is methodologically challenging and the method utilized in this study may serve as one starting point for gathering a larger database in order to answer the question posed by this paper more robustly.

The Cultural Practice of Reading and the Standardized Assessment of Reading Instruction: When Incommensurate Worlds Collide

This article critiques the articles by Connor et al., Croninger and Valli, Pianta and Hamre, and Rowan and Correnti, which appeared in the March 2009 issue of Educational Researcher, by taking a cultural-historical perspective on reading and reading instruction. In this paradigm a number of those authors’ assumptions are seen as questionable, including the beliefs about reading that it is a self-evident construct, that it is a discrete act, and that it is an acultural act. The author of this critique presents evidence that challenges each of these assumptions and argues that by accepting them, the authors of the critiqued articles institute an order that values the system above relational aspects of schooling and teachers’ informed decision making.

Assessing speech perception in young children and relationships with language skills

Few materials are available to assess speech perceptual skills in young children without hearing impairments. However, children with a range of developmental conditions are at risk of speech discrimination deficits. Tasks that reliably assess speech perception skills are thus necessary for research and clinical practice. The development and application of two speech perception tests are described. Data were collected from 105 children, aged 4-5 years, attending mainstream schools, on two tasks, mispronunciation detection and non-word XAB, in quiet and in a background of multi-talker babble. Children’s receptive language skills were also measured. Performance on mispronunciation detection was significantly better than on the XAB non-word task, and significantly better in quiet than in babble. Performance significantly improved with age, and speech discrimination was significantly related to receptive language abilities. Scores obtained in quiet and in babble were highly correlated and findings suggest there may be no advantage to testing in noise, except to avoid ceiling effects on performance. These tasks prove useful in the assessment of young children who may have speech discrimination deficits.

Further Empirical Data on the Psychoeducational Profile-Revised (PEP-R): Reliability and Validation with the Vineland Adaptive Behavior Scales

Abstract The PEP-R (psychoeducational profile revised) is an instrument that has been used in many countries to assess abilities and formulate treatment programs for children with autism and related developmental disorders. To the end to provide further information on the PEP-R’s psychometric properties, a large sample (N = 137) of children presenting Autistic Disorder symptoms under the age of 12 years, including low-functioning individuals, was examined. Results yielded data of interest especially in terms of: Cronbach’s alpha, interrater reliability, and validation with the Vineland Adaptive Behavior Scales. These findings help complete the instrument’s statistical description and augment its usefulness, not only in designing treatment programs for these individuals, but also as an instrument for verifying the efficacy of intervention.

A Nonword Repetition Task for Speakers With Misarticulations: The Syllable Repetition Task (SRT)

Purpose: Conceptual and methodological confounds occur when non(sense) word repetition tasks are administered to speakers who do not have the target speech sounds in their phonetic inventories or who habitually misarticulate targeted speech sounds. In this article, the authors (a) describe a nonword repetition task, the Syllable Repetiton Task (SRT), that eliminates this confound and (b) report findings from 3 validity studies.

Method: Ninety-five preschool children with speech delay and 63 with typical speech completed an assessment battery that included the Nonword Repetition Task (NRT; C. Dollaghan & T. F. Campbell, 1998) and the SRT. SRT stimuli include only 4 of the earliest occurring consonants and 1 early occurring vowel.

Results: Study 1 findings indicated that the SRT eliminated the speech confound in nonword testing with speakers who misarticulate. Study 2 findings indicated that the accuracy of the SRT to identify expressive language impairment was comparable to findings for the NRT. Study 3 findings illustrated the SRT’s potential to interrogate speech processing constraints underlying poor nonword repetition accuracy. Results supported both memorial and auditory–perceptual encoding constraints underlying nonword repetition errors in children with speech-language impairment.

Conclusion: The SRT appears to be a psychometrically stable and substantively informative nonword repetition task for emerging genetic research and other research with speakers who misarticulate.

Level of Education and Category Fluency Task among Spanish Speaking Elders: Number of Words, Clustering, and Switching Strategies

It has been well documented that education influences the individual’s performance on category fluency tasks but it is still unclear how this effect may differ across the different types of category tasks (i.e., animals, fruits, vegetables and clothing). This study aims (1) to analyze the effect of the level of education on four different types of category fluency tasks among elder Hispanic Americans and (2) to provide normative information on a population with different education levels that was previously screened for neurological and psychiatric conditions. In addition this study examines the semantic strategies used by these individuals to complete the fluency tasks. The sample included 105 healthy Hispanic individuals (age 55-98; 29 males and 76 females) divided into three education groups (11 years of education). Results showed that after controlling for age and gender, education has a main effect and is a strong predictor of performance in verbal fluency for the categories animals and clothing with increasing educational attainment being associated with higher category fluency scores and with more switches between categories. These findings suggest that the category fruit is less influenced by level of education than the other three semantic categories and may be a more appropriate test across different educational groups. Results from this study provide a reference for clinicians assessing verbal fluency in Spanish speaking populations.

Girl friendly? Investigating the gender gap in national reading tests at age 11

Results: There were differences between boys’ and girls’ stated enjoyment of the texts in the test. There were differences in the extent to which boys and girls omitted items in the test, with boys, especially lower achieving boys, more likely to omit items than girls. Nine out of 32 items showed a significant differential functioning and there was some relationship between this and the text type to which the item referred.

Conclusions: This investigation suggests that there are differences between boys and girls in their preferences for different genres and in their test-taking strategies.

Learners’ and teachers’ perspectives on language online

This article examines the student and instructor satisfaction with the Language Online courses at Carnegie Mellon University from 2000-2002. These courses were designed with a hybrid format, including reduced face-to-face contact and online delivery of course materials. Quantitative and qualitative data were collected from students and instructors using surveys, interviews, and focus groups. Quantitative data from students indicates a trend of increasing satisfaction with the online courses compared with offline (traditional) courses. Qualitative data were analyzed using QSR NVivo software. Student themes centered on reactions to the reduced schedule of classes and the technology used in course delivery. For instructors, recurring themes included the need for training, control of course materials, and connections with students. The results provide valuable insight for a course format increasingly utilized in university-level language learning.
