The Access to Literacy Assessment System for Phonological Awareness: An Adaptive Measure of Phonological Awareness Appropriate for Children With Speech and/or Language Impairment.

Purpose The Access to Literacy Assessment System-Phonological Awareness (ATLAS-PA) was developed for use with children with speech and/or language impairment. The subtests (Rhyming, Blending, and Segmenting) are appropriate for children who are 3-7 years of age. ATLAS-PA is composed entirely of receptive items, incorporates individualized levels of instruction, and is adaptive in nature. Method To establish the construct validity of ATLAS-PA, we collected data from children with typical development (n = 938) and those who have speech and/or language impairment (n = 227). Results Rasch analyses indicated that items fit well together and formed a unidimensional construct of phonological awareness. Differential item functioning was minimal between the two groups of children, and scores on ATLAS-PA were moderately to strongly related to other measures of phonological awareness. Information about item functioning was used to create an adaptive version of ATLAS-PA. Conclusions Findings suggest that ATLAS-PA is a valid measure of phonological awareness that can be used with children with typical development and with speech and/or language impairment. Its adaptive format minimizes testing time and provides opportunities for monitoring progress in preschool and early elementary classrooms.

Crossing to the other side: Language influences children's perception of event components.

Infants appear to progress from universal to language-specific event perception. In Japanese, two different verbs describe a person crossing a bounded ground (e.g., street) versus an unbounded ground (e.g., field) while in English, the same verb - crossing - describes both events. Interestingly, Japanese and English 14-month-old infants form categories of Japanese ground distinctions in nonlinguistic events while by 20 months, only Japanese-reared infants retain this ability. Five experiments were conducted to investigate the role that language plays in children's ability to form categories of Japanese ground-path distinctions. Experiments 1a and 1b first replicated and extended prior research (Göksun et al., 2011) by showing that 14-month-old English-reared children formed categories of Japanese ground-path while 23-month-old children did not in the presence of general language. Experiment 2a paired a single novel word with different Japanese ground categories and found that language weakened 14-month-old infants' categorization abilities. Experiment 2b showed that labeling these event types differentially allowed 23-month-olds to recognize the Japanese ground-path distinctions that they otherwise would not have detected. To assess whether language uniquely encouraged categorization of Japanese ground-path in Experiment 2b, two different tones were paired with ground-path categories in Experiment 3. The results of Experiments 2b and 3 suggested that language but not tones encouraged ground-path categorization. This study is among the first to show that language can be used to heighten and weaken children's categorization of "non-native" event components.

Novel word learning at 21 months predicts receptive vocabulary outcomes in later childhood.

Several aspects of early language skills, including parent-report measures of vocabulary, phoneme discrimination, speech segmentation, and speed of lexical access predict later childhood language outcomes. To date, no studies have examined the long-term predictive validity of novel word learning. We examined whether individual differences in novel word learning at 21 months predict later childhood receptive vocabulary outcomes rather than generalized cognitive abilities. Twenty-eight 21-month-olds were taught novel words using a modified version of the Intermodal Preferential Looking Paradigm. Seventeen children (range 7-10 years) returned to participate in a longitudinal follow-up. Novel word learning in infancy uniquely accounted for 22% of the variance in childhood receptive vocabulary but did not predict later childhood visuospatial ability or non-verbal IQ. These results suggest that the ability to associate novel sound patterns to novel objects, an index of the process of word learning, may be especially important for long-term language mastery.

An Eye-Tracking Study of Receptive Verb Knowledge in Toddlers.

Purpose: We examined receptive verb knowledge in 22- to 24-month-old toddlers with a dynamic video eye-tracking test. The primary goal of the study was to examine the utility of eye-gaze measures that are commonly used to study noun knowledge for studying verb knowledge. Method: Forty typically developing toddlers participated. They viewed 2 videos side by side (e.g., girl clapping, same girl stretching) and were asked to find one of them (e.g., "Where is she clapping?"). Their eye-gaze, recorded by a Tobii T60XL eye-tracking system, was analyzed as a measure of their knowledge of the verb meanings. Noun trials were included as controls. We examined correlations between eye-gaze measures and score on the MacArthur-Bates Communicative Development Inventories (CDI; Fenson et al., 1994), a standard parent report measure of expressive vocabulary to see how well various eye-gaze measures predicted CDI score. Results: A common measure of knowledge-a 15% increase in looking time to the target video from a baseline phase to the test phase-did correlate with CDI score but operationalized differently for verbs than for nouns. A 2nd common measure, latency of 1st look to the target, correlated with CDI score for nouns, as in previous work, but did not for verbs. A 3rd measure, fixation density, correlated for both nouns and verbs, although the correlation went in different directions. Conclusions: The dynamic nature of videos depicting verb knowledge results in differences in eye-gaze as compared to static images depicting nouns. An eye-tracking assessment of verb knowledge is worthwhile to develop. However, the particular dependent measures used may be different than those used for static images and nouns.

TODDLERS' USE OF GESTURE AND SPEECH IN SERVICE OF EMOTION REGULATION DURING DISTRESSING ROUTINES.

Research on the intersections of young children's emerging communication skills and emotion regulation has increased, following recognition of the link between these skills as they emerge in toddlerhood and the long-term impact of these skills on academic success. However, little is known about how toddlers use gesture and emerging language for emotion regulation. The current study describes toddlers' use of both words and gestures in naturally occurring distressing routines in childcare (diaper change, separation from parents). Seventeen toddlers between 11 and 28 months old were observed over the course of 3½ months in a childcare setting where symbolic gestures ("infant signs") were used as part of daily routines. Results show that toddlers communicated more frequently using gestures than speech, and used a greater range of self-regulatory strategies through gesture than through speech. Moreover, older, verbal toddlers continued to use gestures during heightened distress when they could not find their words. Findings suggest that toddlers use symbolic communication to implement complex and diverse emotion regulation strategies during distressing daily routines, and that gestures provide children with opportunities to employ more diverse emotion regulation strategies than does speech alone, which may ultimately enhance children's abilities to regulate their emotions.

Categorization of dynamic realistic motion events: Infants form categories of path before manner.

Acquiring verbs and prepositions requires categorization of spatial relations. This study examined whether a ground object differentially influences 13- to 15-month-old English-learning infants' categorization of a figure's path (e.g., around; Experiment 1) and manner (e.g., hopping; Experiment 2) of motion in non-linguistic dynamic realistic events. Furthermore, we tested whether categorizing path is "easier" than categorizing manner. Results revealed that infants categorized path only in the presence of a ground object, validating Talmy's definition of path. In contrast, infants categorized manner only in the absence of a ground object. Finally, infants categorizing path showed stronger novelty preferences than those categorizing manner, supporting a primacy of path. Infants showed sensitivity to event components lexicalized in relational terms.

Individual differences in nonlinguistic event categorization predict later motion verb comprehension.

This study probes how individual differences in early event perception predict later verb knowledge. At Time 1, when infants were 13 to 15months of age, they saw videotaped silent scenes performed by a human actor. The goal was to see whether infants could form categories of path (a figure's trajectory with respect to a ground object) and manner (how an action is performed). Infants either saw the same manner (e.g., jogging) taking place across three different paths (around, through, and behind) or saw the same path (e.g., around a tent) taking place across three different manners (running, crawling, and walking). After familiarization, either the path or the manner was changed and visual fixation was monitored using preferential looking. At Time 2, the same children were tested on their comprehension of verbs in a two-choice pointing task showing two simultaneous actions (e.g., running vs. jumping). Success at categorization of path and manner at Time 1 predicted verb comprehension at Time 2, even when taking language knowledge at both time points into account. These preliminary results represent headway in identifying the factors that may contribute to children's language learning. They suggest that skill in categorizing semantic components present in nonlinguistic events is predictive of children's later verb vocabulary.

Six principles of language development: implications for second language learners.

The number of children growing up in dual language environments is increasing in the United States. Despite the apparent benefits of speaking two languages, children learning English as a second language (ESL) often face struggles, as they may experience poverty and impoverished language input at home. Early exposure to a rich language environment is crucial for ESL children's academic success. This article explores how six evidenced-based principles of language learning can be used to provide support for ESL children.

Who is crossing where? Infants' discrimination of figures and grounds in events.

To learn relational terms such as verbs and prepositions, children must first dissect and process dynamic event components. This paper investigates the way in which 8- to 14-month-old English-reared infants notice the event components, figure (i.e., the moving entity) and ground (i.e., stationary setting), in both dynamic (Experiment 1) and static representations of events (Experiment 2) for categorical ground distinctions expressed in Japanese, but not in English. We then compare both 14- and 19-month-old English- and Japanese-reared infants' processing of grounds to understand how language learning interacts with the conceptualization of these constructs (Experiment 3). Results suggest that (1) infants distinguish between figures and grounds in events; (2) they do so differently for static vs. dynamic displays; (3) early in the second year, children from diverse language environments form nonnative - perhaps universal - event categories; and (4) these event categories shift over time as children have more exposure to their native tongue.
