Individual Differences In Video Game Experience: Cognitive Control, Affective Processing, And Visuospatial Processing, Kira Bailey Jan 2009

Individual Differences In Video Game Experience: Cognitive Control, Affective Processing, And Visuospatial Processing, Kira Bailey

Graduate Theses and Dissertations

Independent groups of researchers have investigated video game effects on cognitive control (Mathews et al., 2005), affective processing (Kirsh & Mounts, 2007), and visuospatial processing (Green & Bavelier, 2003). However, no published research has studied all three domains in the same sample of gamers and non-gamers. In the current study nonviolent and violent gamers, and non-gamers performed two tasks tapping each of these three domains; the Stroop and N-back tasks for cognitive control, the picture rating and emotion search tasks for affective processing, and the enumeration and the visual short-term memory tasks for visuospatial processing. Consistent with past research (Bailey, West, & Anderson, 2009), there was a negative relationship between video game experience and proactive cognitive control that was more pronounced in the violent gamers than nonviolent gamers. There was a fundamental shift in the processing of violent and positive affective information in the violent gamers relative ...


Comprehension Of Tools By Orangutans: Causality, Tool Properties, And Manufacture, Kristina Ralene Walkup Jan 2009

Comprehension Of Tools By Orangutans: Causality, Tool Properties, And Manufacture, Kristina Ralene Walkup

Graduate Theses and Dissertations

The study of orangutan (Pongo spp.) cognitive complexity regarding tool use and manufacture is essential for accurate modeling of hominid evolution. Orangutans demonstrated comprehension of causal relations in four studies of tool use and manufacture. Study subjects were 3 captive orangutans (Great Ape Trust, Des Moines, IA). The distinction between rigid and flimsy tools was explored in the first study. The apes demonstrated comprehension by choosing the rigid tools significantly more than the flimsy tools to solve a problem. In the second study, the results provide support for orangutan comprehension of tool and apparatus properties in an extension of the ...


Conceptualizing Design Affordances From A Cognitive Perspective, Jeremiah D. Still Jan 2009

Conceptualizing Design Affordances From A Cognitive Perspective, Jeremiah D. Still

Graduate Theses and Dissertations

The term affordance carries multiple meanings for designers. Traditionally, affordances were discussed within a Gibsonian framework as arising from direct perception of physical constraints. However, some authors extended the meaning to include learned cultural constraints, leading to a theoretical debate about whether designers should draw a distinction between perceptual affordances and learned cultural conventions. In this dissertation it is suggested that a broader meaning of affordance is more appropriate for designers and that a unified account of affordances can be achieved using a cognitive conceptualization of perceived affordances. Within this cognitive framework, perceived affordances arise from automatic processes in the ...
