The journeys of life: Examining a conceptual metaphor with semantic and episodic memory recall

In four studies, we examine the "LIFE IS A JOURNEY" conceptual metaphor using as data output from semantic and episodic memory. In the first three studies output from semantic memory indicates that undergraduate samples, when primed to think in "LIFE" in terms of a course followed until one's 70th year, provided a set of events output in a sequential order and when compared to a second sample, showed high agreement on the ages in which the events would occur. These data were taken as supportive of a "JOURNEY" metaphor in which one progressed along a life path. Study 2 indicated that the "LIFE" events produced also aroused specific subthemes, consistent with the notion of the arousal of lower-level "LIFE-JOURNEY" metaphors (e.g., "LOVE IS A JOURNEY"). In a third study, we experimentally constrained the order of report from semantic memory. These data indicate that free output of events (as in Study 1) involves both a forward-temporal output, and clustering of life themes, but that forcing a forward-temporal order is indicative of the arousal of the superordinate conceptual metaphor but not the lower-level themes. Finally, in an episodic memory task one finds the reverse, namely arousal of the lower-level themes but not of the superordinate conceptual metaphor. Taken together, these findings indicate conditions under which the "LIFE IS A JOURNEY" metaphor is facilitated, and when lower-level metaphors are made more salient. In a more general way, the studies provide a new tool with which to study conceptual metaphors.
