Purpose: When listening to speech under adverse conditions, older adults, even with "age-normal" hearing, face challenges that may lead to poorer speech recognition than their younger peers. Older listeners generally demonstrate poorer suprathreshold auditory processing along with aging-related declines in neurocognitive functioning that…

Purpose: This study sought to evaluate the effects of common hearing aid microphone technologies on speech recognition and listening effort, and to evaluate potential predictive factors related to microphone benefits for school-age children with hearing loss in a realistic listening situation. Method: Children (n = 17, ages 10-17 years) with…

The developmental trajectory of the use of morphemes is still unclear. We investigated the emergence of morphological effects on visual word recognition in German in a large sample across the complete course of reading acquisition in elementary school. To this end, we analyzed lexical decision data on a total of 1,152 words and pseudowords from a…

The genetic effects on individual differences in reading development were examined using genome-wide complex trait analysis (GCTA) in a twin sample. In unrelated individuals (one twin per pair, n = 2,942), the GCTA-based heritability of reading fluency was ~20%-29% at ages 7 and 12. GCTA bivariate results showed that the phenotypic stability of…

The effects of psycholinguistic variables are critical to the evaluation of theories about the cognitive reading system. However, reading research has tended to focus on the impact of key variables on average performance. We report the first investigation examining variation in psycholinguistic effects across the life span, from childhood into old…

Successful spoken language comprehension depends upon both sensory and cognitive processing. Since older adults often experience declines in one or both of these domains, and perform worse on some language processing tasks than younger listeners, an important question is how declines to both auditory perception and cognitive abilities affect…

Modern behavior-genetic studies of twins in the United States, Australia, Scandinavia, and the United Kingdom show that genes account for most of the variance in children's reading ability by the end of the 1st year of formal reading instruction. Strong genetic influence continues across the grades, though the relevant genes vary for reading words…

INDIVIDUAL DIFFERENCES WHICH AFFECT THE ABILITY TO ACQUIRE WORD UNDERSTANDING WERE INVESTIGATED. GROUPS OF EIGHT CHILDREN WERE ADMINISTERED THE "WORD CONTEXT TEST." TWELVE DIFFERENT GROUPS WERE FORMED BY VARYING GRADE LEVEL (THIRD VERSUS SIXTH), SEX, AND SOCIOECONOMIC STATUS (WHITE MIDDLE CLASS, NEGRO LOWER STATUS, AND WHITE LOWER…

Three experiments were conducted to explore the effect of word training on interference patterns in the picture-word task. Subjects were first and second graders. (MP)

Third- and fifth-grade children were presented with a picture-naming interference task to examine the effects of printing words in mixed typecase on children's automatic word processing. (Author/MP)

The amount of conceptual convergence for concepts of nine objects in elementary school children was investigated. Findings revealed substantial convergence on core meanings within and among age groups, and a steady expansion of meaning with age and experience, especially between grades one and three.

Four experiments examined the spelling capability of students in grades 1, 2, 3, 4, 7, and college. Results suggested that reading unit size increases with age and reading ability. Younger children, like adults, unitize common words, and unitization of less common words increases as word configurations become more familiar. (RWB)

Reading encompasses a wide range of verbal processes, among them such simple verbal processes as word decoding, letter recognition, name retrieval, and semantic access. The question is whether simple verbal processing differences are adequate to account for general reading ability differences. Across different verbal domains and different ages,…

The main hypotheses addressed in the research were (1) whether imprecision in the phonological representations of lexical items underlies the impaired expressive naming abilities of disabled readers, and (2) whether weak verbal memory might mediate the relationship between naming and reading skills. From samples of 93 first graders and 67 fourth…
