Since imagery is a unidimensional variable, all measures of imagery, both questionnaires and behavioral, should be correlated; this, however, has not been supported by earlier research. Therefore, a new questionnaire on mental imagery--the Differential Imagery Questionnaire (DIQ)--was developed which taps four types of imagery: word imagery (WI);…

In experiment 1, 22 undergraduates attended a lecture…

This dissertation presents the results of an investigation of visual mental imagery as a strategy hypothesized to increase the amount of interaction with content material and therefore the level of information processing and acquisition, and to assist information retrieval on posttests. Four treatments were used in a crossed, randomized two by two…
