Frequency of occurrence and rankings for touch-related adjectives.

A three-phased study was conducted in order to develop a standardized list of touch-related adjectives. The final list consisted of 306 words that were categorized in 440 instances according to the Lederman and Klatzky (1987, 1990) dimensions of haptic properties (some words were classified in more than one dimension). The Kucera and Francis (1967) frequency of occurrence in written English for all words in the final list was also determined. A correlation was found between frequency of occurrence on the list and Kucera and Francis frequency. An analysis of the word dimensions and future applications are discussed.

Visual and Haptic influences on memory: age differences in recall.

Older (age 60-75) and younger adults (age 20-35) participated in a within-subject experiment. All participants were given four lists of 17 items, a recall test followed each list. Each participant was given a separate list under each of the following conditions, at the rate of 1 item every 10 s. (1) control: list of nouns; (2) visual-only: visually shown objects; (3) visual-and-haptic: given objects to hold and visually examine; (4) haptic-only: blindfolded, given objects to hold. A final surprise recall test was given of all items presented in the study. Data indicated that younger adults recalled more than older adults under all conditions. However, both age groups had the highest recall under the haptic conditions.
