Description
Multimodal presentations have been found to facilitate learning, however, may be a disadvantage for low spatial ability students if they require spatial visualization. This disadvantage stems from their limited capacity to spatially visualize and retain information from both text and diagrams for integration. Similarly, working memory capacity (WMC) likely plays a key role in a learner's ability to retain information presented to them via both modalities. The present study investigated whether or not the act of self-explaining helps resolve deficits in learning caused by individual differences in spatial ability, working memory capacity, and prior knowledge when learning with text, or text and diagrams. No interactions were found, but prior knowledge consistently predicted performance on like posttests. The author presents methodological and theoretical explanations as to the null results of the present study.

Description
The unpleasant bitter taste found in many nutritious vegetables may deter people from consuming a healthy diet. We investigated individual differences in taste perception and whether these differences influence the effectiveness of bitterness masking. To test whether phenylthiocarbamide (PTC) `supertasters' also taste salt and sugar with greater intensity, as suggested by Bartoshuk and colleagues (2004), we infused strips of paper with salt water or sugar water. The bitterness rating of the PTC strip had a significant positive linear relationship with ratings of both the intensity of sweet and salt, but the effect sizes were very low, suggesting that the PTC strip does not give a complete picture of tasting ability. Next we investigated whether various seasonings could mask the bitter taste of vegetables and whether this varied with tasting ability. We found that sugar decreased bitterness and lemon decreased liking for vegetables of varying degrees of bitterness. The results did not differ by ability to taste any of the flavors. Therefore, even though there are remarkable individual differences in taste perception, sugar can be used to improve the initial palatability of vegetables and increase their acceptance and consumption.

Description
Previous research has shown that training visual attention can improve golf putting performance. A technique called the Quiet Eye focuses on increasing a player’s length of fixation between the ball and the hole. When putting, the final fixation is made on the ball before executing the stroke leaving players to rely on their memory of the hole’s distance and location. The present study aimed to test the effectiveness of Quiet Eye training for final fixation on the hole. Twelve Arizona State University (ASU) students with minimal golf experience putted while wearing eye tracking glasses under the following conditions: from three feet with final fixation on the ball, from six feet with final fixation on the ball, from three feet with final fixation on the hole and from six feet with final fixation on the hole. Participant’s performance was measured before training, following quiet eye training, and under simulated pressure conditions. Putting performance was not significantly affected by final fixation for all conditions. The number of total putts made was significantly greater when putting from three feet for all conditions. Future research should test the effects of this training with expert golfers whose processes are more automatic compared to novices and can afford to look at the hole while putting.

Description
Political party identification has an immense influence on shaping individual attitudes and processes of reasoning to the point where otherwise knowledgeable people endorse political conspiracies that support one's political in-group and simultaneously disparage an out-group. Although recent research has explored this tendency among partisans, less is known about how Independents respond in comparison. Previous research fails to identify the Independent as a unique type of voter, but rather categorizes this group as ostensibly partisan, not a separate phenomenon to investigate. However, most Independents purport neutrality and, by recent polls, are becoming a substantial body worthy of concerted focus. Many questions arise about who Independents really are. For example, do all who identify as Independent behave in a similar manner? Are Independents ideologically different than what is represented by a partisan label? Is the Independent category a broad term for something entirely misunderstood? A thorough investigation into the greater dynamics of the political environment in the United States is an enormous undertaking, requiring a robust interdisciplinary approach beyond the focus and intent of this study. Therefore, this study begins the journey toward understanding these phenomena; do Independents, as a whole, uniformly respond to statements about political conspiracy theories? To explore these possibilities, explicit responses are bypassed to evaluate the implicit appeal of political conspiracy theories. An action dynamics (mouse-tracking) approach, a data rich method that records the response process, demonstrates Independents are not in fact a homogeneous group, but rather seem to fall into two groups: non-partisan leaning and partisan leaning. The analysis exposes that relative to the baseline and control stimuli: (1) Non-leaning Independents reveal an increased susceptibility to implicitly endorse bi-partisan directed conspiracy theories when compared to leaners. (2) Republican-leaners demonstrate a stronger susceptibility to endorse right-wing aligned conspiracy theories (against Barack Obama), similar to Republican partisans. (3) Democrat-leaners, unlike Democrat partisans, do not demonstrate any particular susceptibility to implicitly endorse either right/left-wing aligned conspiracy theories (against Barack Obama or George W. Bush). Drawing from major theories from social, political, and cognitive psychology will contribute to an understanding of these phenomena. Concluding remarks include study limitations and future directions.

Description
Magnocellular-Dorsal pathway’s function had been related to reading ability, and visual perceptual learning can effectively increase the function of this neural pathway. Previous researches training people with a traditional dot motion paradigm and an integrated visual perceptual training “video game” called Ultimeyes pro, all showed improvement with regard to people’s reading performance. This research used 2 paradigms in 2 groups in order to compare the 2 paradigms’ effect on improving people’s reading ability. We also measured participants’ critical flicker fusion threshold (CFFT), which is related to word decoding ability. The result did not show significant improvement of reading performance in each group, but overall the reading speed improved significantly. The result for CFFT in each group only showed significant improvement among people who trained with Ultimeyes pro. This result supports that the beneficial effect of visual perceptual learning training on people’s reading ability, and it suggests that Ultimeyes pro is more efficient than the traditional dot motion paradigm, and might have more application value.
