Chapter One introduces the field of evolutionary psychology as well as provides a review of factors influencing facial attractiveness. Chapter Two presents empirical evidence that online studies may provide a distorted perspective on cross-cultural face preferences since online samples are not representative of the populations in developing countries. In El Salvador, participants without internet access preferred more feminine men as well as heavier and more masculine women when compared to participants with internet access. One possible explanation for such findings is that the level of harshness in the environment may be influencing preferences. One individual difference that is influenced by environmental harshness is age of menarche. Chapter Three thus provides exploratory evidence that age of menarche also influences masculinity preferences. Chapter Four further examines this environmental harshness hypothesis by repeatedly testing students undergoing intensive training at an army camp. Increases in the harshness of the environment led to an increased male attraction to cues of higher weight in female faces. Such changes in preferences may be adaptive because they allow for more opportunities to form partnerships with individuals who are better equipped to survive. An alternative explanation for the empirical findings in Chapters Two and Four is that familiarity may also influence preferences. Chapter Five tests this familiarity hypothesis by examining the faces of participants in different areas of El Salvador and Malaysia. Rural participants preferred heavier female faces than urban participants. Additionally, the faces of female participants from rural areas were rated as looking heavier. This finding suggests that familiarity may indeed influence attractiveness perceptions. Lastly, Chapter Six draws conclusions from the empirical findings reported in Chapters Two-Five and lists proposals of future research that could further enhance our understanding of what we find attractive.

Both response to intervention (RTI) and recognition and response systems recommend the use of evidence-based teaching strategies and individualized data collection to monitor the students' response to such strategies. In addition to the efficacy of interventions, individual stakeholders should have a voice in which intervention is implemented. Constant prompt delay and progressive prompt delay procedures have been routinely implemented and have been proven to be effective at teaching important skills to a variety populations; however, no objective data has been reported on the stakeholders' preference for such procedures. Thus, the purpose of the present study was to evaluate the relative efficacy of as well as the relative preference for prompt delay procedures. Four preschool children experienced three teaching conditions: constant prompt delay, progressive prompt delay, and a control condition. A multi-element design was used to evaluate the relative efficacy of the prompt delay procedures at teaching pre-academic tasks while a modified concurrent chains arrangement was used to evaluate each child's relative preference for each teaching strategy. The results for efficacy of and preference for prompt delay procedures were idiosyncratic for all participants. These results as well implication of the results are discussed.

Siblings of children who have been diagnosed with autism can play important roles in the lives of their brothers or sisters. Previous literature shows that siblings can effectively change behavior and can increase play interactions. Furthermore, the use of preferred materials may enhance social interactions between the siblings. The purpose of this study was to determine, the effects that material preferences and choices have on sibling social bids and cooperative play during a sibling training program. There were two main objectives. The first objective was to evaluate the effects of teaching with the high preference toy of the neuro-typical sibling during sibling training. The second objective was to determine if the training would produce different effects across four different toy conditions. Measures included social bids made by each of the siblings and cooperative play. Results indicate that teaching with the neuro-typical siblings' high preference toy during sibling training can be an effective method to increase social bids and cooperative play. The results of this study are discussed in the contexts of preference and choice selections, physical environments, motor skills, carry over effects, and participations based on gender.
