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.

Detection of letter repetition in words and nonwords: the effect of opposite-case distractors.

This study tested whether it is the repetition of the letter's name and not its shape that is detected faster in a word than in a nonword (Krueger, 1989). Ss judged whether the same letter shape or the same letter name was repeated in a 6-letter word or nonword. When the shape was repeated, the word advantage was nearly as large (about 50 ms) when Ss looked for a physical match as when they looked for a name match. When the 2 repeated letters differed in case, however, the word advantage was very large (208 ms) when Ss looked for a name match and were thus rewarded for nonvisual coding, but the advantage vanished ((-35)-ms word deficit) when Ss looked for a physical match and were thus penalized for nonvisual coding. This indicates that letter names are much more accessible in words than in nonwords, and that words are primarily encoded nonvisually.

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.

The effect of goal-setting and feedback on age differences in secondary memory.

Goal-setting and feedback have been found to improve performance on a variety of tasks. The present study applied this finding to an examination of adult age differences in secondary memory. Elderly and young adults completed a free-recall task in which one subgroup established a performance goal for blocks of trials and received feedback on a trial-by-trial basis. A second, comparison subgroup completed the same task without setting goals or receiving feedback. Results indicated that the use of the motivational technique of goal-setting and feedback increased memory performance of both age groups beyond that obtained under standard recall conditions.
