In the present study, the speech-recognition performance of 50 subjects aged 63 to 83 years was measured for a wide range of materials (nonsense syllables, monosyllabic words, sentences) and listening conditions (presentation levels of 70 and 90 dB SPL, both in quiet and in a noise background). In addition to complete audiologic evaluations, measures of auditory processing (the Test of Basic Au...

Abstract Introduction Adenotonsillectomy (AT) is the most common surgical treatment for pediatric obstructive-sleep-apnea (OSA) with fair effectiveness. There are still controversies about improvement of neurocognitive function after AT. This study investigates changes AT in preschool and school age children OSA, including intelligence attention, explore inconsistent improvements by comparing d...

The study compared performance of 23 adolescents with ID on the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV), one of the most widely used intelligence tests, and thr...

There is some evidence that insufficient effort may be common in schizophrenia, posing significant threats to the validity of neuropsychological test results. Low effort may account for a significant proportion of variance in neuropsychological test scores and the generalized cognitive deficit that characterizes the disorder. The current study evaluated clinical predictors of insufficient effor...

What's the neurocognitive deficit as an endophenotype to familial schizophrenia? Here, we investigate the neurocognitive endophenotype in first-episode patients with familial schizophrenia (FS) and sporadic schizophrenia (SS), and their parents. 98 FS patients and their 105 parents; 190 SS patients and their 207 parents; 195 controls matched with patients, and 190 controls matched with the pati...

PURPOSE This study examined the prediction of performance on measures of the Story Goodness Index (SGI; Lê, Coelho, Mozeiko, & Grafman, 2011) from executive function (EF) and memory measures following traumatic brain injury (TBI). It was hypothesized that EF and memory measures would significantly predict SGI outcomes. METHOD One hundred sixty-seven individuals with TBI participated in the st...

This study investigated the concurrent validity of the Wechsler Intelligence Scale for Children— Third Edition (WISC-III; Wechsler, 1991) and Form 6 of the Cognitive Abilities Test (CogAT6; Lohman & Hagen, 2001a).
