The aim of this thesis was to extend existing imagery ability literature. After reviewing the literature in Chapter 1, Chapter 2 validated and modified the Movement Imagery Questionnaire-Revised to provide a more comprehensive assessment of movement imagery ability. Known as the Movement Imagery Questionnaire-3, it was employed in Chapter 3 to examine the influence of prior movement and prior o...

The purpose of this research was to amend the Vividness of Movement Imagery Questionnaire (VMIQ; Isaac, Marks, & Russell, 1986) in line with contemporary imagery modality and perspective conceptualizations, and to test the validity of the amended questionnaire (i.e., the VMIQ-2). Study 1 had 351 athletes complete the 3-factor (internal visual imagery, external visual imagery, and kinesthetic im...

Aims. While studies on healthy subjects have shown a partial overlap between the motor execution and motor imagery neural circuits, few have investigated brain activity during motor imagery in stroke patients with hemiparesis. This work is aimed at examining similarities between motor imagery and execution in a group of stroke patients. Materials and Methods. Eleven patients were asked to perfo...

The factors that influence whether an athlete chooses to engage in imagery are largely unknown. One reason may be the amount of confidence athletes have in their ability to image. The aim of this study was to examine the relationships among efficacy in using imagery, imagery use and imagery ability. Consistent with Bandura's (1986, 1997) theory, it was hypothesized that there would be a positiv...

It is well established that the mental simulation of actions involves visual and/or somatomotor representations of those imagined actions. To investigate whether the total absence of vision affects the brain activity associated with the retrieval of motor representations, we recorded the readiness potential (RP), a marker of motor preparation preceding the execution, as well as the motor imager...
