This pioneering investigation is based on a longitudinal research, expanding over a 3 year period, exploring the Psychological and Social aspects of infertility and infertility treatment on Persian (henceforth referred to as Iranian) infertile couples attending infertility clinics in Tehran. In phase 1 of the investigation an 85-item questionnaire in Farsi (Persian) was developed and validated, based on a four point Likert-type scale measuring the following factors: Psychological Distress, Social Extroversion, Marital Satisfaction, Attitudes Towards Modem Medicine and Religious Beliefs. In phase 2 of the investigation, lasting over a period of two years, the above 85-item questionnaire was administered at three time phases, namely: initial assessment (when patients first attended the clinic for the purpose of diagnosis of their problem), during In Vitro Fertilisation (IVF) treatment (24 hours before egg collection), and a week after an unsuccessful treatment cycle. The same questionnaire was also administered to fertile couples (the control group) attending the clinics for routine and non-fertility related treatment at three time phases (about three weeks between each administration). The data from the patient group (n = 37 couples) and control group (n = 10 couples), together with data obtained from the general population (n = 197) i.e. those who responded to the items for the purpose of validating the questionnaire (norms), was subjected to statistical analysis. In comparison to norms and control group, infertile patients were more psychologically distressed. This finding is true for both men and women investigated. The degree of this psychological distress, however, is significantly greater for women than for men. Standard Multiple Regression Analyses of the infertile patients' data showed that the main predictors of psychological distress were gender, marital satisfaction, attitudes towards modem medicine, and religious beliefs. F or female patients, marital satisfaction was a significant predictor of their psychological distress. Marital satisfaction was the main contributing factor to the socially withdrawn behaviour of the patients. In phase 3 of the investigation, a year after data collection, examination of patients' notes showed that 7 out of the 37 infertile couples eventually had successful IVF with a term pregnancy. Results of a Stepwise Regression Analysis showed that the degree of psychological distress was the main predictor of pregnancy. In particular, couples who eventually conceived scored lower on psychological distress measures than those who did not. These findings are discussed in line with comparable reported literature on a mainly Western population, and implications of the findings for future research and counselling of infertile patients are outlined.

Research in cultural psychology suggests that East Asians are more likely than North Americans to be sensitive to contextual information. By contrast, much evidence suggests that even North Americans judgments are influenced by affective priming information, the effect of which can be seen as another type of contextual cue. However, the magnitude of such priming effect has not been tested in a cross-cultural context. Using the methodology of the affective priming paradigm, we conducted two studies, in which we manipulated (a) the timing of priming information (simultaneous vs. sequential) and (b) the type of affective information (background landscape vs. background human figures), in which European Canadians and Japanese judged either happy or sad facial expressions in the focal area of the scene. The results indicate that the two cultural groups are similar when contextual information is salient, but only Japanese remain sensitive to context with subtle cues.

Using a mixed methods approach, this dissertation included two studies exploring procrastination and academic motivation beliefs of adolescents from Canada and Thailand. Study 1 examined the relationships between procrastination, motivation beliefsself-efficacy, self-efficacy for self-regulated learning, self-esteem, and test anxietyand academic performance and explored significant predictors of adolescent procrastination across two cultures. In this study, 312 Canadian and 401 Thai adolescents from secondary schools in an urban area in western Canada and an urban area in North-Eastern Thailand completed a 47-item survey containing procrastination and four motivation measures. In Study 2, semi-structured interviews were conducted with 14 Thai adolescents representing low and high achieving students, to provide additional information about the role of motivation on adolescent procrastination and investigate academic procrastination of Thai adolescents in more depth. The quantitative findings demonstrated that all motivation variables significantly predicted procrastination, with self-efficacy for self-regulated learning strongly influencing adolescents across cultures. Findings from the qualitative study revealed six themes pertaining to academic procrastination: a) definitions of procrastination, b) antecedents of procrastination, c) consequences of procrastination, d) overcoming procrastination, e) the role of motivation, and f) the role of cultures on motivation, achievement, and procrastination. Quantitative and qualitative findings were integrated and discussed in order to provide insights into adolescent procrastination. Theoretical and educational implications as well as suggestions for future research were also provided. / Psychological Studies in Education

Products are designed to satisfy user needs. Thus, industrial designers are expected to have a thorough understanding of user needs and to incorporate those understandings into the design of products; however, it is not a straightforward task for designers to translate their conditional understanding into a product. The gap between product and user can be even wider when latent user needs, such as cultural ones, are calculated into the problem. Therefore the meanings and functions imbued in products by the designer may not be recognized and acknowledged by users, due to the differences in cultural preferences of designers and users from separate cultures. In spite of the fact that user satisfaction has been extensively supported in the design literature, it seems that such an approach allows only a passive role for designers, who actually act as cultural intermediaries; that is, the designers' role is merely presumed to catalyze the process and match user requirements to the end product. Thus, the impact of designers' cultural preferences is considered as incidental, or at least overlooked. A content analysis method was triangulated to collect and analyze diverse visual and textual data relating to the concept generation stage of the product development process. To collect data, professional industrial designers in the two culturally diverse countries of Australia and Iran were recruited to participate in half-hour design exercise sessions to sketch to a design brief, followed by responding to an interview questionnaire. The analysis of data revealed that: (1) designers' cultural preferences do influence their approaches toward tackling the design problem; (2) there are nexuses between the design aspects of the concepts generated and the cultural dimensions of the values of the societies in which the designers were born and has lived, and; (3)potential users can unconsciously comprehend the meaning invested in the product by the designer. This thesis breaks new ground for further advancing the study of the Designer-Precedent Approach (DPA) in other cultural and social contexts, while it challenges the conventional approaches of user-centered design (UCD) broadlyperceived as the ultimate method of incorporating users' wants into products.
