Abstract
Our main objective was to analyze the role of imageability in relation to the age of acquisition (AoA) of nouns and verbs in Spanish-speaking children with Down syndrome (DS) and their peers with typical development (TD). The AoA of nouns and verbs was determined using the MacArthur-Bates CDIs adapted to the profile of children with DS. The AoA was analyzed using a linear mixed-effect model, including factors of imageability, group, and word class, and controlling for word frequency and word length. This analysis showed that high imaginable and short words were acquired early. Children with DS acquired the words later than TD peers. An interaction between imageability and group indicated that the effect of imageability was greater in the DS group. We discuss this effect considering DS children's phonological memory difficulties. The overall results confirm the role that imageability and word length play in lexical acquisition, an effect that goes beyond word class.

Abstract
OBJECTIVES We completed a registered double-blind randomized control trial to compare acclimatization to two hearing aid fitting algorithms by experienced pediatric hearing aid users with mild to moderate hearing loss. We hypothesized that extended use (up to 13 months) of an adaptive algorithm with integrated directionality and noise reduction, OpenSound Navigator (OSN), would result in improved performance on auditory, cognitive, academic, and caregiver- or self-report measures compared with a control, omnidirectional algorithm (OMNI). DESIGN Forty children aged 6 to 13 years with mild to moderate/severe symmetric sensorineural hearing loss completed this study. They were all experienced hearing aid users and were recruited through the Cincinnati Children's Hospital Medical Center Division of Audiology. The children were divided into 20 pairs based on similarity of age (within 1 year) and hearing loss (level and configuration). Individuals from each pair were randomly assigned to either an OSN (experimental) or OMNI (control) fitting algorithm group. Each child completed an audiology evaluation, hearing aid fitting using physically identical Oticon OPN hearing aids, follow-up audiological appointment, and 2 research visits up to 13 months apart. Research visit outcome measures covered speech perception (in quiet and in noise), novel grammar and word learning, cognition, academic ability, and caregiver report of listening behaviors. Analysis of outcome differences between visits, groups, ages, conditions and their interactions used linear mixed models. Between 22 and 39 children provided useable data for each task. RESULTS Children using the experimental (OSN) algorithm did not show any significant performance differences on the outcome measures compared with those using the control (OMNI) algorithm. Overall performance of all children in the study increased across the duration of the trial on word repetition in noise, sentence repetition in quiet, and caregivers' assessment of hearing ability. There was a significant negative relationship between age at first hearing aid use, final Reading and Mathematical ability, and caregiver rated speech hearing. A significant positive relationship was found between daily hearing aid use and study-long change in performance on the Flanker test of inhibitory control and attention. Logged daily use of hearing aids related to caregiver rated spatial hearing. All results controlled for age at testing/evaluation and false discovery rate. CONCLUSIONS Use of the experimental (OSN) algorithm neither enhanced nor reduced performance on auditory, cognitive, academic or caregiver report measures compared with the control (OMNI) algorithm. However, prolonged hearing aid use led to benefits in hearing, academic skills, attention, and caregiver evaluation.
