Grasping Type Affects Configural Encoding In Visual Working Memory, Shinhae Ahn
Grasping Type Affects Configural Encoding In Visual Working Memory, Shinhae Ahn
Arts & Sciences Electronic Theses and Dissertations
Previous research has shown that different grasping actions selectively influence the processing of simple visual features based on their relevance to the specific action. However, it remains uncertain if this interaction extends to abstract and higher-order information, such as global configuration extracted from an array of visual objects. The present study aimed to investigate the impact of different grasping types on the processing of configural shape information in visual working memory (VWM). In Experiment 1, participants engaged in a VWM change detection task while adopting either power- or precision-grasping postures. The availability of configural shape information was manipulated through the …
Discounting Of Delayed And Probabilistic Outcomes Across The Adult Lifespan, Haoran Wan
Discounting Of Delayed And Probabilistic Outcomes Across The Adult Lifespan, Haoran Wan
Arts & Sciences Electronic Theses and Dissertations
Intertemporal and risky decision-making predicts many problem behaviors that also decline with age, raising the question: Do intertemporal and risky decisions change with age? Despite the theoretical and empirical importance, the literature under both rubrics reveals inconsistent findings. Some studies suggest that these inconsistencies may be due to the presence of unassessed demographic differences. The present study examined age differences, evaluating the role of demographic variables in intertemporal and risky choice of gains and losses using the discounting framework. Four experiments were conducted, each with one of the four types of discounting: discounting of delayed gains, discounting of delayed losses, …
