Tactual performance test (TPT) Halstead-Reitan neuropsychological test battery for adults (HRNTB)

The TPT employs a version of the Seguin-Goddard form board, a flat wooden puzzle board into which differently-shaped blocks can be placed. Without using vision (usually a blind-fold is used) the subject must place the blocks in the board board using the dominant, non-dominant, and both hands. The time to complete each of these tasks serves as a score and their sum gives the TPT-Total time (TPT-T) score. Afterward, the sbuject is asked to recall the shape and location of the blocks. These yield TPT-memory (TPT-M) and TPT-Localization (TPT-L) scores.

This test provides a variety of measures, particularly manual dexterity, spatial memory, tactile discrimination. Note that Lezak (1995, p. 493) argues that this tests administration procedures are particularly discomforting and distressing to individuals with brain injuries or among the elderly. She argues that it should only be given under special circumstances.
