The effect of aging on human brain spatial processing performance
Bibliographic record
Abstract
Cognitive abilities similar to other mental or physical abilities develop and change during the course of life. Spatial processing is a cognitive ability, which has been suggested to deteriorate by age. The focus of this paper is to study the change of real time egocentric spatial processing in humans by age. For this, an interactive computer game played with a 2DOF manipulandum was designed. The game consists of goal-oriented motor tasks, in which the player must move the robot arm toward a desired spatial cue in a virtual 2D environment in every trial for a total number of 72 trials. The spatial cues are four final destinations and a starting location, which change their position in every new trial of the game. 37 individuals with no cognitive impairment were split into 3 groups according to different age range (children, young, and elderly) and participated in this experiment. Their spatial processing ability was assessed and compared between the age groups. The results show the children (7-12 y) and elderly (65(+) y) performed very similar and significantly worse than the young adult participants.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
