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...

Research indicates that calculus students often imagine objects losing a dimension entirely when a limit is taken, and that this image serves as an obstacle to their understanding of the fundamental theorem of calculus. Similar imagery, in the form of “indivisibles”, was similarly unsupportive of the development of the fundamental theorem in the mid-1600s, unlike the more powerful subsequent im...

Objectives: This study examined the effects of exercise imagery on implicit and explicit attitudes towards exercise and the moderating effect of exercise status. It was predicted that exercise imagery would activate a pattern of positive automatic associations with exercise that would be reflected in more positive implicit attitudes. Corresponding effects were expected for explicit affective at...

OBJECTIVE To investigate, using PET and H2(15)O, brain activation abnormalities of patients with PD during motor imagery. To determine whether motor imagery activation patterns depend on the hand used to complete the task. BACKGROUND Previous work in PD has shown that bradykinesia is associated with slowness of motor imagery. METHODS The PET study was performed in eight patients with PD wit...

Brain-computer interface (BCI) technology has the prospects of helping stroke survivors by enabling the interaction with their environ ment through brain signals rather than through muscles, and restoring motor function by inducing activity-dependent brain plasticity. This paper presents a clinical study on the extent of detectable brain signals from a large population of stroke patients in usi...

In this paper, we address a method for motor imagery feature extraction for brain computer interface (BCI). The wavelet coefficients were used to extract the features from the motor imagery EEG and the linear discriminant analysis was utilized to classify the pattern of left or right hand imagery movement and rest. The performance of the proposed method was evaluated using EEG data recorded by ...

Mental imagery, seeing with the mind's eyes, can induce stronger positive as well as negative affect compared to verbal processing. Given this emotion-amplifying effect, it appears likely that mental images play an important role in affective disorders. According to the subcomponents model of depression, depressed mood is maintained by both negative imagery (which amplifies negative mood) and l...

the hyrcanian forests have been highly exploited in recent decades by human impacts. easy access, abundance and variety of valuable forest yields have led to population growth density, creation of new residential areas and deforestation activities. change detection is one of the main methods of management and evaluation of natural resources. we investigated forest changes in southern surroundin...

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...

Activation of motor-related areas has consistently been found during various motor imagery tasks and is regarded as the central mechanism generating motor imagery. However, the extent to which motor execution and imagery share neural substrates remains controversial. We examined brain activity during preparation for and execution of physical or mental finger tapping. During a functional magneti...
