Does The Presence Of A Non-Coincident Visual Spatial Pattern Facilitate Spatial Pattern Learning? Implications For A Dedicated Spatial Pattern Learning System, Scott Katz
Electronic Theses and Dissertations
Spatial pattern learning is defined as an ability to learn spatial relationships of objects in space without the use of discrete visual landmarks or environmental geometry (Brown & Terrinoni, 1996). Spatial pattern learning has been suggested to be a distinct form of learning because it is not affected by cue competition and has been shown to occur in the absence of discrete landmarks and environmental geometry (Brown, Yang, & DiGian, 2002; Sturz Brown, & Kelly, 2009). In the proposed study, the distinctness of spatial pattern learning was investigated. Specifically, human participants searched in an interactive 3-D computer generated virtual environment …
Evaluating The Utility Of A Virtual Environment For Childhood Social Anxiety Disorder, Nina Sarver
Evaluating The Utility Of A Virtual Environment For Childhood Social Anxiety Disorder, Nina Sarver
Electronic Theses and Dissertations
Objective: Two significant challenges for the dissemination of social skills training programs are (a) the need to provide sufficient practice opportunities to assure skill consolidation and (b) the need to assure skill generalization (i.e., use of the skills outside the clinic setting). In the case of social anxiety disorder, virtual environments may provide one strategy to address these issues. This investigation describes the development of an interactive skills-oriented virtual school environment and evaluated its utility for the treatment of social anxiety disorder in preadolescent children (Study 1). This environment included both in-clinic and at-home solutions. In addition, a pilot replication/extension …
Inescapable Aversive Stimulus Decreases Subsequent Escape Responding In Humans: An Investigation Of The Learned Helplessness Effect In A 3d Virtual Environment, Zachary Kilday
Electronic Theses and Dissertations
Exposure to an inescapable aversive stimulus decreases escape responses to subsequent escapable aversive stimuli. This is known as the learned helplessness effect. In the present experiment, human participants were trained in an immersive, 3D virtual environment analog of an operant chamber using an inescapable aversive stimulus, an escapable aversive stimulus, or no aversive stimulus. Then, all participants were tested using an immersive, 3D virtual environment analog of a shuttle box using an escapable aversive stimulus. Participants trained with an inescapable aversive stimulus were slower to escape during testing than participants trained with an escapable aversive stimulus. The current results demonstrate …
