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...

background and aim: research shows that 13-18 percent of the people suffer from tinnitus, almost 5 percent of which, have chronic or bothersome tinnitus. chronic tinnitus may be accompanied by anxiety, depression, insomnia, and impairment in cognitive functions such as memory and attention. the purpose of this study was to compare the verbal auditory memory and divided attention between individ...

The effects of incentive and preparation on performance and classification accuracy of standard and malingering-specific tests were investigated in a simulation study using a 2 (no incentive vs. a $20 incentive) x 2 (immediate vs. delayed preparation) factorial design. Eighty undergraduate students and 15 individuals with traumatic brain injury were administered standard (viz., Digit Span and V...

Studies using dichotic listening tasks have reported findings suggestive of alterations of cerebral laterality in schizophrenia and affective disorders. In a review of these findings, an effort was made to take into account four factors: (1) type of dichotic listening task; (2) performance level; (3) clinical state of patients at the time of testing; (4) diagnostic subtype of patients. A conver...

In previous behavioral studies, a prime syllable was presented just prior to a dichotic syllable pair, with instructions to ignore the prime and report one syllable from the dichotic pair. When the prime matched one of the syllables in the dichotic pair, response selection was biased towards selecting the unprimed target. The suggested mechanism was that the prime was inhibited to reduce confli...
