Introduction
Preliminary Results
Discussion
Results shown are mean ratings of the observers
for each model and ear worn device condition.
(e.g. CH Caucasian observer and Hispanic model,
HC Hispanic observer and Caucasian model, etc.)
Hispanics make up 14.8 of the total population
in the United States, 44.3 million people (Census
Bureau, 2005). The prevalence of hearing loss
among this population is estimated between 10
and 23. Of those that have a hearing loss of 40
dB HL or greater, only 12 use hearing aids
(Kennedy Deapen, 1991, Lee et. al
1991). According to Sergio Kochkin, in 2004 of
the 32.5 million people who had a hearing loss
only 23.5 had adopted the use of amplification.
There is a significant difference in the use of
hearing aids between the Hispanic population and
that of the national average a difference of
11.5. There are many different reasons that
contribute to the lack of adoption of hearing
aids among minorities in general. Such reasons
are cost (Franks, 1985), insurance (Lee et. al.,
1996) and low consumer awareness (Kennendy
Deapen, 1991). In 1977, Blood and colleagues
found the lack of hearing aid use was due to
cosmetic and perceived negative stigma. This was
defined as the hearing aid effect. There has
been extensive work looking at the hearing aid
effect in various populations. However, there
is relatively little empirical evidence of the
cultural stigmas that may exist between and
within the Hispanic population using different
ear worn devices which may be contributing
factors to the low adoption rate of hearing aid
use among the Hispanic population. The purpose of
this study was to examine how Hispanics
(primarily Mexican-American and South American),
as compared with Caucasians, judge members of
their own race and of a different race wearing
and not wearing different styles of ear worn
devices on the basis of appearance, personality,
assertiveness, and achievement.
Graphs shown are preliminary results
demonstrating interesting trends.
  • Between subjects, Caucasians were routinely rated
    higher in all 4 domains.
  • Between ear worn device style, with exception to
    the Bluetooth condition, the Hispanic models were
    routinely rated more negatively than their
    Caucasian counterpart (by both Caucasian and
    Hispanic raters).
  • The Bluetooth condition reveals in the
    Assertiveness and Achievement Domains the
    Hispanic models were routinely rated more
    positively, regardless of observer, compared to
    all other ear worn device conditions. The
    assessment of more positive character in the
    Domains of Assertiveness and Achievement can
    potentially be attributed to the use/adoption of
    new technology, otherwise known as the
    Technology Halo Effect. Perhaps the use of the
    Bluetooth by the Hispanic model lessens the
    negative self-image among Hispanics due to the
    Technology Halo Effect.
  • The Hispanic observers rated the Hispanic models
    more negatively in all ear worn device styles and
    in all 4 domains compared to the ratings by
    Caucasian observers. This suggests a more
    general culturally/racially mitigated self-image
    among the Hispanic sample.

Taking a closer look, the differences in observer
ratings between the most visible, FS-ITE, ear
worn device condition and the None ear worn
device condition show the following trends

Range maximum possible -3 to 3
  • The Caucasian observers rated the Hispanic models
    more negatively in the FS-ITE condition as
    compared to the None condition. Whereas, the
    Hispanic observers showed more positive judgments
    for Hispanic models in the FS-ITE condition.
  • The Hispanic observers varied greatly regarding
    their ratings as compared to the Caucasian
    observers in all 4 domains.

These pilot participants were not prompted to
look for models wearing and/or not wearing an ear
worn device. According to findings by Johnson
et. al., we would expect the OF condition and the
None condition to demonstrate comparable
results, however, preliminary results of this
investigation demonstrate no similar consistency
between these ear worn device conditions.
Although Caucasians models, rated by both
Caucasians and Hispanics, were rated more
positively in the Domains of Personality,
Assertiveness, and Achievement the ratings of
Hispanic models, by both Caucasian and Hispanic
raters, are not consistently in the same
direction. There is a more negative perception
of the Hispanic models regardless of the type of
ear worn device or race of the observer
(Caucasian or Hispanic). Future direction of the
study would be
Methods
Subjects 24 adult subjects. 11 Caucasian (6
Females, 5 Males) and 13 Hispanic (7 Females, 6
Males) with normal hearing and vision
participated in the study. Stimuli 11

Domain II
- Caucasians rated the Hispanic FS-ITE group more
negatively (-0.41) compared to the Hispanic None
group (0.13). - Preliminary trends reflect no
difference in judgment by Hispanic observers for
either group under the two conditions.
- Caucasians rated the Hispanic and Caucasian
FS-ITE group more negatively compared to the None
group respectively. - Hispanic observers rated
the Caucasian FS-ITE group (0.79) less compared
to the Caucasian None group (1.10).
  • Add to the instructions given to the observers
    that the models they will be looking at may or
    may not be wearing an ear worn device and to look
    for this before making their judgments regarding
    appearance, personality, assertiveness, and
    achievement.
  • Further research the impact of the Technology
    Halo Effect in mitigating cultural bias.
  • Examining greater specificity among subjects of
    their Hispanic cultural ID (e.g.
    Mexican-American, Cuban-American, etc.)

- No significant trend regarding judgment between
conditions for the Hispanic observers. -
Caucasian observers rated the FS-ITE models, both
Caucasian and Hispanic, more negatively than the
None models.
- Caucasians rated the Hispanic FS-ITE group more
negatively (-0.16) compared to the Hispanic None
group (0.31). - Hispanic observers rated the
FS-ITE models, both Caucasian and Hispanic, more
positively than the None models.
