The Facts on Aging Quiz 2 was given to 20 undergraduate majors in communicative disorders, 20 first-semester graduate students, and 20 final-semester graduate students. All groups scored barely above the guessing level, suggesting that the facts on aging are not being learned through an infusion approach as students progress through their training.
Professionals in four health-care disciplines were given the Facts on Aging and Mental Health Quiz to assess their knowledge in these areas. All groups scored means above 70%, indicating considerable knowledge which would help in their provision of services to older adults.
Eighteen school children with unilateral hearing loss were compared to their peers through administration of the Screening Instrument for Targeting Educational Risk (SIFTER) to their teachers. Results indicate that children with unilateral hearing loss are given SIFTER scores significantly lower than their peers in all five SIFTER areas of academics, attention, communication, participation, and behavior. Such results support previous findings regarding teachers' attitudes toward students with unilateral hearing loss and indicate a need for in-service education for the classroom teacher and special attention to the educational risks of such children.

The effects of three instructional sets (conventional Carhart-Jerger, strict, and lax) and of two stimulus presentation methods (continuous tones, pulsed tones) on pure-tone thresholds and false-alarm responses were determined for 20 male subjects. False alarms were tallied during hearing measurement periods and during 30-second time-out periods totaling nine minutes of time-out per subject. Results showed that 50% of the subjects made false-alarm responses to some extent at 250, 1000, and 4000 Hz. Instructions and stimulus mode, along with frequency, affected the number of false alarms, but thresholds under the experimental conditions were unchanged. It is suggested that a method for assessing and controlling false alarms is an important clinical consideration.

The purpose of this investigation was to select a list of spondees from the CID W-1 spondee word list that eliminates the need for familiarization but produces spondee thresholds equivalent to those obtained with familiarization. Forty-eight subjects with normal hearing responded to familiarized and unfamiliarized spondee words at their familiarized spondee threshold levels. Spondee words that were correctly identified most often without prior familiarization or whose correct response rates were least altered by familiarization were selected for the final list. Seventeen words were selected from the criteria of the present study; two of these words were excluded from the final list since they did not fall within the recommended 4-dB range. The 15 remaining spondee words without familiarization produced spondee thresholds equivalent to the entire CID W-1 list with familiarization in a direct comparison of the two lists in 20 subjects with normal hearing.

Differences in the Bekesy tracking levels of continuous (C) and interrupted (I) tones at both threshold and most comfortable loudness (MCL) were determined in a large clinical sample of persons with hearing loss. Results indicate small but significant C-I differences not only at the two levels separately but also in the tracking of C and I tones at threshold relative to MCL, regardless of frequency or hearing loss severity. Such results may have implications for both diagnostic and rehabilitative audiology.
A survey of communications problems among elderly persons was conducted to determine the perceived incidence, the number of agencies that provide various services, provision/nonprovision of speech and hearing services, and need for in-service training in the area of communications disorders. Results indicate that older persons with communications disorders are underestimated and underserved. A majority of the additional in-service training in the areas of communications and communications disorders.
