Assessing Malleability of Spatial Abilities in Down Syndrome

Study Summary

Based on available literature and our own preliminary research, the researchers have concluded that persons with Down syndrome (DS) exhibit difficulties in utilizing the specific spatial abilities of mental rotation and perspective taking and performing complex spatial tasks such as wayfinding and environmental learning. A weakness in spatial abilities may have many direct applications to daily life, ranging from activities such as tying shoes to using hand tools and navigating the environment. Spatial abilities also serve as a cognitive foundation for many other complex skills such as solving mathematical problems and using spatial language for giving and receiving directions. Moreover, spatial abilities are used in a variety of specialty jobs such as grocery stocking, packaging, and assembling, which are among the most commonly reported jobs for adults with DS. Hence, a new focus on spatial ability and its modifiability in persons with DS is clearly warranted. The primary goal of the research proposed in this application is to evaluate the malleability of mental rotation and perspective taking in people with DS through providing intentional experience with numerous spatial activities. Two groups of participants will be tested over the course of the project: adolescents and young adults with DS and typically developing (TD) children. Following an initial evaluation of performance on the two abilities, participants will receive up to eight sessions of spatial activity experience utilizing puzzle construction, block building, and computer search tasks. Following the experience sessions, spatial abilities of participants will be re-evaluated. These data will be used to investigate two specific aims. First, the researchers investigate whether spatial abilities of persons with DS can be modified by experience with spatial activities. Second, the researchers investigate whether the degree of modification observed for persons with DS can reduce performance differences bet

Primary Outcome

The Mental Rotation Assessment was used to assess ability to match objects rotated at varying degrees from a standard. Number of correct matches out of 18 possible matches over all rotations (excluding 0 degrees) was used as a measure of performance. Minimum score = 0. Maximum score = 18. Higher scores reflect better performance. Change in Mental Rotation Ability was calculated by subtracting Baseline (Time 1) Assessment scores from 8 Week (Time 2) Assessment scores.
