60 (-.10) .44 (-.26) .70 Dual processing systems The evidence indicates that "imag ery" effects in memory are not con sonant with a strictly verbal encoding view. The viewpoint that currently holds sway (for instance, Atwood 1969 ; Bower in press; Paivio 1969) is that nonverbal imagery and verbal sym bolic processes are the two major components of thinking. These com ponents are distinguished b...

219 Abstract— The principle of contralateral organization of the visual and motor systems was exploited to investigate contributions of the cerebral hemispheres to the mental representation of prehension in healthy, right-handed human subjects. Graphically rendered dowels were presented to either the left or right visual field in a variety of different orientations, and times to determine wheth...

To investigate the effect of negative motor imagery on corticospinal excitability, we performed transcranial magnetic stimulation (TMS) studies in seven healthy subjects during imagination of suppressing movements. Subjects were asked to imagine suppression of TMS-induced twitching movement of their nondominant left hands by attempting to increase the amount of relaxation after receiving an aud...

This study had two purposes. First, in order to address the controversy regarding activation of the primary visual area (PVA) during visual mental imagery, regional cerebral blood flow (rCBF) was recorded while subjects performed a task that required high-resolution visual mental imagery. Second, in order to discover whether verbal descriptions can engage visual mechanisms during imagery in the...

The ability to form positive mental images may be an important aspect of mental health and well-being. We have previously demonstrated that the vividness of positive prospective imagery is increased in healthy older adults following positive imagery cognitive training. The rostral anterior cingulate cortex (rACC) is involved in the simulation of future affective episodes. Here, we investigate t...

One application that merits closer examination is the use of SPOT panchromatic imagery (10 meter resolution) to detect and monitor troops massing along an international border, near a demarcation line, or at key transportation nodes deep within a country. If commercial imagery acquired by the SPOT satellites or by comparable remote sensing systems could be used for such a purpose, the analysis ...

Editorial on the Research Topic Mental Imagery in Clinical Disorders Mental imagery refers to the simulation or recreation of perceptual experience across different sensory modalities (1, 2). The study of mental imagery has clinical relevance because such imagery has been increasingly shown to play a key role across various psychological disorders (3, 4). The current research topic presents a d...

In two studies, we examined the strength of relationship between internal and external visual imagery with kinaesthetic imagery. In Study 1, 56 participants completed the Vividness of Movement Imagery Questionnaire and the Movement Imagery Questionnaire. Pearson's product-moment correlations failed to reveal a significant correlation between external visual imagery and kinaesthetic imagery. How...

It has been reported that congenital prosopagnosics may have a general imagery deficit or an imagery deficit specific to faces. However, much of this evidence is based on self-report questionnaires, rather than experimentally based testing (Grüter et al., 2007, 2009). This study tested face and non-face based imagery in a case series of congenital prosopagnosics, utilising both questionnaire ba...

The functional mechanisms and the neural correlates of visual mental imagery (the faculty whereby we can use our "mind's eye" to visualize objects in their absence) are at the centre of a lively debate in cognitive neuroscience. Neurocognitive models have proposed a functional equivalence between visual perception and visual mental imagery, which would be subserved by common neural substrates, ...
