The influence of a gender system in a language on perception was examined in a cross-cultural study. Participants were from two language groups, one with a gender system, Spanish, and the other with a limited gender system, English. In each language group, participants were from three age groups: 5-7 years old, 8-10 years old, and adult. In one experiment, participants were asked to put a typical male or female name to 20 objects. In another experiment, participants were asked to assign attributes to the objects. Language gender tags influenced the Spanish adults and the 8- to 10-year-olds in their choice of gender assignment, whereas perceived attributes influenced the younger Spanish children and English speakers (both adults and children). It appears that in a language with a grammatical gender system, such as Spanish, the gender system creeps into perception after the gender tags have been acquired.

Objectives: The objectives of this study were to (1) evaluate the extent to which school-age children benefit from fundamental frequency (F0) differences between target words and competing two-talker speech, and (2) assess whether this benefit changes with age. It was predicted that while children would be more susceptible to speech-in-speech masking compared to adults, they would benefit from differences in F0 between target and masker speech. A second experiment was conducted to evaluate the relationship between frequency discrimination thresholds and the ability to benefit from target/masker differences in F0. Design: Listeners were children (5-15 years) and adults (20-36 years) with normal hearing. In the first experiment, speech recognition thresholds (SRTs) for disyllabic words were measured in a continuous, 60-dB-SPL two-talker speech masker. The same male talker produced both the target and masker speech (average F0 = 120 Hz). The level of the target words was adaptively varied to estimate the level associated with 71% correct identification. The procedure was a four-alternative forced-choice with a picture-pointing response. Target words either had the same mean F0 as the masker or it was shifted up by 3, 6 or 9 semitones. To determine the benefit of target/masker F0 separation on word recognition, masking release was computed by subtracting thresholds in each shifted-F0 condition from the threshold in the unshifted-F0 condition. In the second experiment, frequency discrimination thresholds were collected for a subset of listeners to determine whether sensitivity to F0 differences would be predictive of SRTs. The standard was the syllable /ba/ with an F0 of 250 Hz; the target stimuli had a higher F0. Discrimination thresholds were measured using a three-alternative, three-interval forced choice procedure. Results: Younger children (5-12 years) had significantly poorer SRTs than older children (13-15 years) and adults in the unshifted-F0 condition. The benefit of F0 separations generally increased with increasing child age and magnitude of target/masker F0 separation. For 5-to 7-year-olds, there was a small benefit of F0 separation in the 9-semitone condition only. For 8-to 12-year-olds, there was a benefit from both 6-and 9-semitone separations, but to a lesser degree than what was observed for older children (13-15 years

Frequency discrimination was measured in 5- to 11-year-olds and adults with normal hearing. The standard stimulus was either a 250-Hz tone or the syllable /ba/ with a fundamental frequency (F0) of 250 Hz. Target stimuli were higher in frequency than the standard, and the threshold for frequency discrimination was determined adaptively for each of the two stimulus types separately. For both the tone and /ba/ stimuli, thresholds improved approximately linearly with the log of child age, reaching adult levels by 11.5 years of age. There was no evidence of an effect of stimulus type.

Hearing parents of deaf children face stresses and demands related to parenting a deaf child, including difficult choices about language, technologies, education and identity for their children (Marschark, 1997). To date, few researchers have discussed the unique challenges faced by this group. Through a series of semistructured, in-depth interviews with 18 parents, this study investigated the experiences of hearing parents of deaf children spanning various life stages. A phenomenological approach identified 5 themes most pertinent to understanding their experiences. Each theme offers insight, particularly for professionals, into the distinctive issues that might arise at the time of diagnosis of deafness and reveals the challenges hearing parents face when confronted with a barrage of decisions, including choice of oral or sign language, mainstream or special deaf education, and identity with the hearing or Deaf community. The central message from this work is to inform hearing parents of deaf children and professionals working with these parents of the likely challenges that they may face.

Purpose The purpose of this study was to evaluate speech-in-noise and speech-in-speech recognition associated with activation of a fully adaptive directional hearing aid algorithm in children with mild to severe bilateral sensory/neural hearing loss. Method Fourteen children (5–14 years old) who are hard of hearing participated in this study. Participants wore laboratory hearing aids. Open-set word recognition thresholds were measured adaptively for 2 hearing aid settings: (a) omnidirectional (OMNI) and (b) fully adaptive directionality. Each hearing aid setting was evaluated in 3 listening conditions. Fourteen children with normal hearing served as age-matched controls. Results Children who are hard of hearing required a more advantageous signal-to-noise ratio than children with normal hearing to achieve comparable performance in all 3 conditions. For children who are hard of hearing, the average improvement in signal-to-noise ratio when comparing fully adaptive directionality to OMNI was 4.0 dB in noise, regardless of target location. Children performed similarly with fully adaptive directionality and OMNI settings in the presence of the speech maskers. Conclusions Compared to OMNI, fully adaptive directionality improved speech recognition in steady noise for children who are hard of hearing, even when they were not facing the target source. This algorithm did not affect speech recognition when the background noise was speech. Although the use of hearing aids with fully adaptive directionality is not proposed as a substitute for remote microphone systems, it appears to offer several advantages over fixed directionality, because it does not depend on children facing the target talker and provides access to multiple talkers within the environment. Additional experiments are required to further evaluate children's performance under a variety of spatial configurations in the presence of both noise and speech maskers.
