Ikoniska auktoriteter är personer som tillskrivs sådan betydelse att de kommit att symbolisera delar eller aspekter av samhällslivet eller epoker i historien och som kan sägas ha haft ett betydande inflytande på samhället och kulturen. I studien undersöktesom ikoniska auktoriter påverkar oss mer eller annorlunda än andra källor. I ett experiment fick högskolestudenter uppdelade i fyra grupper läsa en text under hög elaboration om en psykologisk teori där variablerna ikonisk auktoritet och personligrelevans manipulerades. Deltagarna ombads sedan skatta vilken trovärdighet de ansåg att teorin hade. Studien ställde upp två hypoteser: att hög ikonisk aukto-ritet skulle öka den skattade trovärdigheten och personlig relevans minska den. Resultatet gav inte stöd åt någon av hypoteserna men en interaktionseffekt visade att texten vid låg personlig relevans uppfattades som mer trovärdig av de deltagare som exponerades för låg ikonisk auktoritet än de deltagare som exponerades för hög ikonisk auktoritet. Det föreslås att interaktionen beror på en backlash-effekt.

This study investigated the influence of semantic complexity treatment in individuals with fluent aphasia on discourse performance. Semantic treatment is an effective way to improve semantically based word retrieval problems in aphasia. Treatment focused on the semantic application of the Complexity Account of Treatment Efficacy (CATE) (Thompson, Shapiro, Kiran, & Sobecks, 2003) promotes training of complex items resulting in generalization to less complex, untrained items. In addition, research has shown that the personal relevance of treatment material can increase treatment efficacy. This study investigated the effect of semantic treatment of atypical personally relevant items among individuals with aphasia on discourse performance. Two treatment phases were applied to examine the influence of personally relevant and non-relevant treatment material on discourse performance. In addition, generalization from trained atypical items to untrained typical items was investigated. Methods and procedures were partially replicated from Kiran, Sandberg, & Sebastian (2011) examining semantic complexity within goal-derived (ad hoc) categories. Three participants with fluent aphasia were trained on three semantic tasks including category sorting, semantic feature generation/selection, and Yes/No feature questions. A generative naming task was used for probe data collection every second session. Stimuli consisted of atypical items only. The hypothesis that semantic complexity training of personally relevant items from ad hoc categories will produce greater generalization to associated, untrained items than training of non-relevant items and consequently increase discourse performance was not supported. The findings revealed a failure to replicate the magnitude and type of improvements previously reported for the typicality effect in generative naming. Clinical significance was found for personally relevant and non-relevant discourse performance. However, no consistent pattern was found within and across participants. In addition, effect size for generalization from trained atypical to untrained typical items was not significant. Limitations of this study lead to future directions to further specify participation selection, such as cognitive abilities, procedural changes, and the inclusion of discourse performance as an outcome measure. Overall, the results of this study provide weak support for replicating semantic treatment of atypical exemplars in ad-hoc categories and hence demonstrate the critical role of replication across labs to identify key issues in the candidacy, procedures, and outcome measurement of any developing treatment.

The purpose of this study is to use a constructivism as a referent to investigate how students learn physics in a Taiwanese career college classroom. Forty-nine first year, engineering major first students participated in this study of teaching and learning in my college level classroom. The theoretical framework for the study was based on the five dimensions of the Constructivist Learning Environment Survey (CLES) (Taylor & Fraser, 1991: Taylor, Fraser & White, 1994; Taylor, Fraser & Fisher, 1997), namely Personal Relevance, Student Negotiation, Shared Control, Critical Voice, and Uncertainty. These dimensions were employed as analytic themes to examine the qualitative data. / A total of six lessons were observed: two lecture classes, two laboratory practice sessions, and two group discussion sessions. My qualitative observations, supplemented by video- and audio-recordings, of these six lessons were used to produce six classroom narratives. These six narratives were analyzed individually and then comparatively using a cross case analysis whereby the five dimensions of the CLES were employed as analytic themes. The CLES questionnaire was administered at the commencement of the semester and again at the end of the semester in order to determine any quantitative changes in students’ perceptions of their classroom environment. The various analyses were used to make several propositions about the constructivist nature of my classroom. I conclude the study with a discussion of the implications of the study and my reflections on the thesis experience. / The study found that, in my Taiwanese career college physics classroom, (a) the teacher plays a central role in establishing the overall classroom learning environment, (b) student group dynamics are important in the classroom learning environment, (c) the central role of content often works against the establishment of a constructivist classroom, (d) cultural factors play a large role in determining the constructivist nature of the classroom, (e) language plays an important role in the construction of the learning environment, and (f) the students’ learning attitude affected the classroom environment.

Information seeking and information avoidance are the mechanisms humans natural used for coping with uncertainties and adapting to environmental stressors. Uncertainties are rooted in knowledge gaps. In social sciences, the relationship between knowledge gaps and perceived risk have received little attention. A review of the information science literature suggests that few studies have been devoted to the investigation of the role of this relationship in motivating information-seeking behavior. As an effort to address the lack of theory building in the field of information science, this study attempts to construct a model of information seeking under risk (MISR) by examining the relationships among perceived risk, knowledge gap, fear arousal, risk propensity, personal relevance, and deprivation and interest curiosity as antecedents to motivation to seek information. An experimental approach and a scenario-based survey method are employed to design the study. Partial least square structural equation modeling (PLS-SEM) analysis was conducted to test the relationships in the proposed model. Perceived risk was found to be a highly significant predictor of information seeking in moderately high-risk situations. Similarly, personal relevant has a significant negative effect on perceived risk and its interaction with knowledge gap motivates information seeking.
