The French version of the 24-item VMIQ uses a 5-point Likert-type scale to measure the imagery vividness of a movement in two conditions.
During the baseline phase, measures of softball players' vividness of movement imagery were collected once a week through the administration of the French version of the VMIQ (see Figure 1).
To control individual differences in movement imagery abilities, the participants were selected as in the pilot study using the VMIQ
. Forty normal imagers were thus selected and assigned to five groups.
Finally, the VMIQ
and manipulation check were administered after all treatments.
RM-ANOVAs for each of the VMIQ sections (over four trials) have indicated that the three treatment groups did not differ significantly from each other during the four trials.
The RM-ANOVAs applied to the VMIQ sections of imaging one-self's body parts, the movement of body parts, and the movement of the whole body, have shown trial effects F(3,30)=3.39; p [is less than] .03, F(3,30)=6.97; p [is less than] .001, and F(3,27)=3.74; p [is less than] .02 respectively.
The mean VMIQ
imagery ability scores were IVI = 92.33 (N = 9), EVI = 89.33 (N = 9) for each group.
5 = no image at all, you only 'know' that you are thinking of an object (VVIQ) the skill (VMIQ
In addition to the VVIQ and VMIQ
items, subjects were also asked three questions related specifically to imagery in cricket.
In the second experiment EEG was recorded while subjects generated images of movements in response to items from the VMIQ
. The EEG recorded during each experiment was subsequently analysed to determine whether differences exist at specific cortical loci during imagery and between good and poor imagers as measured by VMIQ
and by MRT scores.
Finally, the Vividness of Movement Imagery Questionnaire (VMIQ
) (Isaac et al., 1986) is a kinesthetic version of Marks' (1973) VVIQ.
The test-retest (three-week interval) reliabilities for a group of 57 children were 0.87 for the VVIQ and 0.86 for the VMIQ
. An alternate halves reliability computed on 100 randomly selected participants revealed the following: VVIQ (using items 1-8 vs.
