Subjects were 101 Mexican-American adults (53 females, 48 males), age range 17-72, and most often were in the blue-collar job level. Instructions were that (a) 18 pairs of slides would be shown; (b) each slide would be projected for 15 seconds; (c) each of the two models was to be judged on intelligence, attractiveness, friendliness, happiness, and success; and (d) the rating scale would be marked corresponding to the left or right slide. Results indicated the lighter-skinned models were judged more favorably than the darker ones on all five dimensions. To the extent this study sheds light on an important cultural value, it is hoped the treatment of Mexican-Americans in therapy will be facilitated and improved.

Intersectional analyses have made clear that Black women as a group fare far worse in employment outcomes than their race and gender counterparts. However, there is little research that examines differences among Black women. The purpose of this dissertation is to examine how Black women are perceived intra-intersectionally, or within the intersection of race and gender. Black women are not monolithic and it is important to illuminate how they are perceived differently from one another. This dissertation explores the effects of differences in skin tone and hair texture among Black women seeking a management position. It was hypothesized that Black women with lighter skin and/or straight hair would be characterized more positively than Black women with darker skin and/or kinky hair; this hypothesis was not supported. However, for negative characteristics, the hypothesis that Black women with darker skin would be characterized more negatively than Black women with lighter skin was confirmed. Further, it was found that hair texture significantly interacts with skin tone such that darker-skinned Black women with kinky hair were characterized more negatively than light-skinned women with kinky hair. There were no significant differences found between the skin tone and hair texture of Black women on salary offers, but there was a marginally significant skin tone effect for perceptions of success in that lighter-skinned Black women are perceived to be more successful than darker-skinned Black women. This study sheds light on the need to look at the intersection of both skin tone and hair texture in order to fully understand how negative stereotypes apply to Black women.

Poor diet precipitates significant social and economic burden, necessitating effective and economical dietary intervention strategies. Current population-level campaigns provide guidelines for living healthily and focus on the impact of lifestyle on chronic disease risk. Behavioural interventions which capitalise on individuals' existing cognitions are likely to be more effective. A programme of work is presented here which evaluates the feasibility and efficacy of an appearance-based dietary intervention approach. This project aims to improve fruit and vegetable consumption by illustrating the associated benefits to skin appearance. The impact of fruit and vegetable consumption on skin colour is assessed (Chapter 6), corroborating previous between-subjects evidence which finds that dermal yellowness (CIE b*) is positively associated with fruit and vegetable intake. This work also discovers that modest within-subject dietary change is sufficient to perceptibly alter skin colour within six weeks (Chapter 7). Perceptual preferences are examined (Chapters 5 to 9), finding that optimally healthy skin colouration is that associated with increased fruit and vegetable consumption. Two behavioural intervention trials are conducted (Chapters 6 and 9) to evaluate whether visualising the impact of fruit and vegetable consumption on skin colour motivates dietary improvement. Relative to control groups, participants receiving an appearance-based intervention (in which the above effects are illustrated and explained) reported improvements in diet, particularly when illustrations were performed upon images of one's own face. It may be valuable to disseminate such an intervention at a population level, though a number of further longitudinal studies are necessary to determine the wider effectiveness of this approach.
