title: Tactile measures in the structure of intelligence.
abstract: This study investigated the relationship of tactile abilities within the framework of a hierarchical structure of mental abilities. Data were analysed from 229 participants who were administered tactile measures from the Dean-Woodcock Sensory Motor Battery along with a battery of conormed cognitive measures representative of the Cattell-Horn-Carroll (CHC) model of intelligence. Multiple measures of tactile performance were used including Palm Writing and Object Identification, and each measure included a lateralized measure (i.e., right/left). Factor analytic results suggest tactile measures have a significant relationship with measures of cognitive ability. In this study, tactile measures involving object identification were more related to cognitive measures of visual processing-speed and overall processing speed; whereas, tactile measures involving the recognition of numbers written on the palm of the hand produced high loadings on a separate factor. Results from this study suggest different tactile measures may differentially load on cognitive factors depending on the common processing demands of the tactile and cognitive measures. Suggestions for differentiating common processing demands between tactile and cognitive measures are discussed.
