Dichotic word recognition was evaluated in free-recall, directed-attention right, and directed-attention left response conditions. All participants were right-handed and included a group of young adults with normal hearing and two groups of older adults with sensorineural hearing loss. Dichotic word recognition performance was best for young adults and decreased for each older group. A right-ea...

Objective: The aim of this study was to investigate whether people exposed to the Chinese Famine in fetal period or in multiple stages of childhood are associated with cognitive decline in adulthood. Furthermore, the nutritional environment of adulthood was explored as an important factor in this correlation. Methods: 1162 adults born between 1952 and 1964 were recruited. They were divided into...

This project focused on the individual differences underlying observed variability in temporal processing among older listeners. Four measures of vowel temporal-order identification were completed by young (N=35; 18-31 years) and older (N=151; 60-88 years) listeners. Experiments used forced-choice, constant-stimuli methods to determine the smallest stimulus onset asynchrony (SOA) between brief ...

Dichotic Interaural Intensity Difference (DIID) training was designed to address deficits in dichotic processing. The present review describes the theoretical and physiologic bases for this procedure, highlighting the available efficacy data that are currently available. Additionally, a new approach to the DIID (i.e., DIID II) is presented in which interaural timing deficits are utilized during...

OBJECTIVE In this study, different kinds of memory were evaluated using Rey Auditory Verbal Learning (RAVLT) test and were compared between two groups of typical and gifted students using Digit Span test. Finally, we determined if working memory interfered with scores in different Rey stages or not. MATERIAL & METHODS This study was conducted in Tehran City, Iran in 2013. Scores on RAVLT were...

Test of digit retention was carried out to investigate if the usually accepted norm of 7 forward digit retention holds true in our population. The highest mean score of 8.85 was obtained by executives. Professionals scored a mean of 8.08 followed by students (7.81). Housewives, skilled workers and unskilled workers scored less than the accepted norm of 7 digit forward retention. A strong influe...
