TY - CONF T1 - 24. Long-Term Memory Recall and Mental Rotation Accuracy within an Augmented Reality Sandbox AU - Patton, Nathaniel Thomas Ignacio AU - Mittelman, Emily AU - Neese, Sydney AB - We examined the accuracy of mental rotation and spatial recall within an augmented reality sandbox to study the effects of two-dimensional and three-dimensional learning. The goal of the study was to gain feedback about the ability to use an augmented reality sandbox for learning spatial relationships and testing spatial memory. Using Piaget’s Three Mountain Task (Robinson & Robinson, 1983) as a basis for our study, at encoding participants were shown either a two-dimensional image of a landscape or a three-dimensional landscape created in the sandbox, both the same scale (2x3 feet). Participants were given 30 seconds to commit the landscape to memory. Participants then engaged in a distractor task for 3 minutes to clear their short-term memory. Participants were then asked to recreate the landscape that was provided but from a rotated point of view. We found that correctly created scenes from three-dimensional encoding recreations (M=4.50 SD=1.27) contain more accurately placed features than the two-dimensional recall (M=2.42 SD=.90), t(20)=4.50, p DA - 2017-3-24 PY - 2024 PB - unav N1 -
