Three experiments investigated the learning of simple associations in a color-word contingency task. Participants responded manually to the print colors of 3 words, with each word associated strongly to 1 of the 3 colors and weakly to the other 2 colors. Despite the words being irrelevant, response times to high-contingency stimuli and to…

This article examines how probability (lexical frequency and previous mention), speech style, and prosody affect word duration, and how these factors interact. Participants read controlled materials in clear and plain speech styles. As expected, more probable words (higher frequencies and second mentions) were significantly shorter than less…

In the present study, we have applied a word association procedure for assessing conceptual change in science education, leaning on the presuppositions of the theory of social representations. The proposed method was applied both before and after a university population ecology course. Our results have shown that the teaching procedure can change…
