Previous work suggests that both concrete (e.g., hat, shoes) and abstract (e.g., god, devil) concepts with spatial associations engage attentional mechanisms, affecting subsequent target processing above or below fixation. Interestingly, both facilitatory and inhibitory effects have been reported to result from compatibility between target location and the meaning of the concept. To determine the conditions for obtaining these disparate effects, we varied the task (detection vs. discrimination), SOA, and concept type (abstract vs. concrete) across a series of experiments. Results suggest that the nature of the concepts underlies the different attentional effects. With abstract concepts, facilitation was observed across tasks and SOAs. With concrete concepts, inhibition was observed during the discrimination task and for short SOAs. Thus, the particular perceptual and metaphorical associations of a concept mediate their subsequent effects on visual target processing.

Due to the increasing diversity of mathematics classrooms today, teachers need guidance on how to support English Learners (ELs) in mathematics classes in a way that situates language learning within mathematical activity. Unfortunately, neither mathematics education research nor EL education research is sure how to navigate the complexity of teaching ELs mathematics while supporting both their language development and their mathematical development through their participation in mathematical activity. This study examined ELs' participation in mathematical Discourse, investigating both the mathematical purposes ELs accomplished by using multiple symbol systems, and the way ELs used non-English language (NEL) symbol systems to support their spoken English. The participants were college-aged ELs beginning their studies at the English Learning Center at an American university. The students all had fluency with basic conversational English, and had many different levels of mathematical experience. I identified five categories of purposes in which ELs engaged during mathematical Discourse. I also developed the Replace Augment Learn (RAL) framework that describes how ELs used NEL symbol systems to make up for their decreased English literacy and facilitate their participation in mathematical Discourse. Analysis of the data suggests ELs' use of NEL symbol systems (1) played a significant role in achieving many of the purposes associated with mathematical Discourse, and (2) opened up a space for effective language acquisition. These findings indicate that authentic mathematical activity can be a productive site for language development, and that ELs with basic conversational English and literacy with a variety of symbol systems can participate meaningfully in mathematical Discourse.

Drawing is valued as a non-verbal assessment tool to measure children's conceptual development and emotional state. Drawing has also been described as a problem-solving activity and unique symbol system. Although drama has been known to facilitate learning in other symbol systems, such as reading and writing, and to bring about advances in perspective taking and understanding of emotion, its impact on drawing has not been previously examined. In this study, Kindergarten and first grade children were instructed to draw a happy tree, sad tree, and angry tree before and after a 10-hour drama intervention. Half of the children participated in the intervention while the remaining children were members of a control group who participated in the regular school program. Consistent with expectations, children who participated in the drama program showed significantly greater improvement from pretest to posttest in drawing emotion compared to control children. Their drawings of emotion improved in clarity, that is, they depicted more clearly the emotion they were instructed to convey. Participants in the drama program also used significantly more highter level drawing strategies. The results suggest that the experience in emotional perspective taking provided by dramatic play may generalize to the domain of drawing and enhance expression.

Cross-cultural differences in the perception of pictorial material has long been established and documented. In the Republic of South Africa, which is increasingly globalized, and where it is appealing from financial, economic and training perspectives, the temptation is to use Western-based AAC symbol systems and strategies in intervention with clients from other language and cultural orientations. The aim of this study was to determine the translucency ratings of specific Blissymbols as rated by six-to seven-year-old Setswana-speaking children. A secondary aim was to determine whether the ratings changed after second and third exposures in order to determine the learnability of these symbols. A brief comparison was made between the results of the current study and the results reported in the Quist et al., study (1998). Thirty-five Setswana learners were exposed to 93 selected Blissymbols, based on a study by Quist et al., (1998). A three-point semantic differential scale, consisting of three faces accompanied each Blissymbol. Participants marked the face that best described his/her perception of the specific symbol’s iconicity. This procedure was repeated over a period of three days. The results indicated that the translucency ratings of the majority of the Blissymbols ranged from moderate to high. The research further demonstrated significant differences in translucency ratings between the first and second exposures, suggesting learning of the symbols. A smaller difference was noted between Days 2 and 3. A correlation in findings was noted between the current study and the Dutch and US studies (Quist et al., 1998). / Dissertation (M (Augmentative and Alternative Communication))--University of Pretoria, 2007. / Centre for Augmentative and Alternative Communication (CAAC) / MA / unrestricted

Summaries in Afrikaans and English / The transformative mission of the White Paper on Education (1995: 19) states that the South African education system is moving towards a single, national, non-racial system where all people are offered equil opportunities. Demographic and other changes make particular demands on the education system. The HSRC (1987:54) claim that distance edcation is increasingly viewed as a possible solution for educational problems. The literature study aims to motivate, from an andragogic-didactical perspective, the use of two-dimensional silent images in study material. A literature study was also undertaken on the perception of silent images and the elements involved in the perception of depth, movement, size, colour, etc., from which certain didactic guidelines were deducted with a view to the design of silent images. The ability of distance education students to identify the elements above, was emperically researched. The validity of the didactic guidelines were verified in this phase. / Die transformatiewe missie van die Witskrif vir Onderwys (1995: 19) stel dit dat die Suid-Afrikaanse onderwysstelsel oorgaan na 'n "enkele nasionale, nie-rassige stelsel" waar daar gelyke geleenthede vir aile mense gebied word.
