Abstract:
Three empirical studies and one analysis of pre-existing data were performed to determine the everyday meanings of time, a major component of phenomenological analyses of human experience. To this end, participants in Studies 1 and 2 sorted time related words into groups having similar meanings, with these groups then evaluated by hierarchical clustering procedures. Results of Studies 1 and 2 produced similar clustering patterns suggesting it was possible to define the everyday meanings of time in terms of experiences of change and continuity, linear organization, tempo, and boundaries. Results of Study 3 indicated little or no effect on clustering patterns of time words when space words also were included in the set of items to be sorted. Concerns about the size and representativeness of the words used as stimuli in Studies 1, 2 and 3 led to an analysis of over 2,000 words falling under the general heading of Time in Roget's Thesaurus. Results of this analysis revealed that clusters comparable to those obtained in the other three studies also appeared in these data. These results were discussed in terms of their implications for the way in which "invisible" concepts such as time are thought about and used, particularly as related to figurative expression.
