The purpose of this study was the examination of age bias in social work professionals who have direct and influential contact with a growing segment of the population: older adults. Those who work most closely with older people may be at risk for age bias, although much of the research on age bias has been conducted with students rather than with those who work with older people. This study adds to the research on prejudice; the sources from which attitudes, values, prejudices, and stereotypical thinking arise were addressed. Key experiences with older individuals were found to predict age bias. Because social work ethical principles closely align with conditions known to reduce prejudice, it was hypothesized that higher ethics adherence would be associated with less age bias. Specific experiential factors were found to influence prejudice toward older people. Influences from family beliefs and from television and other media were associated with a non-biased attitude, as were influences from caregiving to older people. These sources of one's values and beliefs about older individuals were also found to predict the extent of one's knowledge of aging processes. Although ethics adherence was not a predictor of age bias, the discovery of the influence of family beliefs, media portrayals, and caregiving experiences revealed a need for awareness of ageist beliefs in a professional population that works extensively with older adults. / Ph.

Basic facial emotion recognition is suggested to be negatively affected by puberty onset reflected in a “pubertal dip” in performance compared to pre- or post-puberty. However, findings remain inconclusive. Further, research points to an own-age bias, i.e., a superior emotion recognition for peer faces. We explored adolescents’ ability to recognize specific emotions. Ninety-five children and adolescents, aged 8–17 years, judged whether the emotions displayed by adolescent or adult faces were angry, sad, neutral, or happy. We assessed participants a priori by pubertal status while controlling for age. Results indicated no “pubertal dip”, but decreasing reaction times across adolescence. No own-age bias was found. Taken together, basic facial emotion recognition does not seem to be disrupted during puberty as compared to pre- and post-puberty.
