Evaluation of context effects in dynamic touch

Previous research has shown that the inertia tensor underlies the perceptio n of an object's magnitudes by dynamic touch. This research was directed at whether the tensor consistently constrains perception across variations in presentation conditions. In experiments in which participants wielded rods with or without attached weights, the tenser's influence on perceived leng th was unaffected by an uneven distribution of rod lengths (Experiment 1) a nd by different adaptation levels within a narrow (Experiment 2) or wide (E xperiment 3) range. Traditional context manipulations are motivated by conc erns extrinsic to the type of system underpinning perception by wielding; g iven the dynamical nature of this perceptual system, potential contextual i nfluences may have to be sought in manipulations that are dynamically motiv ated.
