Visual imagery and perception share several functional properties and apparently share common underlying brain structures. A main approach to the scientific study of visual imagery is exploring the effects of mental imagery on perceptual processes. Previous studies have shown that visual imagery interferes with perception (Perky effect). Recently we have shown a direct facilitatory effect of vi...

Research has demonstrated the effectiveness of imagery use in sport, but only few studies have examined the theoretically connection between imagery and confidence in team sports. These neglect necessitated the need to examine imagery use as predictors of elite football players’ sport confidence. Descriptive data were collected from forty-three male and female football players from Nigeria usin...

This study was conducted to explore how the level of imagery in a radio advertisement affects the allocation of cognitive resources to encoding the message into memory. A within-subjects experiment was conducted in which participants listened to 24, 60-second radio advertisements that had been coded as either highor low-imagery messages. Secondary-task reaction time was obtained during exposure...

Visual- and motor imagery rely primarily on perceptual and motor processes, respectively. In healthy controls, the type of imagery used to solve a task depends on personal preference, task instruction, and task properties. But how does the chronic loss of proprioceptive and tactile sensory inputs from the body periphery influence mental imagery? In a unique case study, we investigated the image...

Biological motion perception is often claimed to support social cognition, and to rely upon embodied representations and motor imagery. Are people with higher levels of social traits or more vivid motor imagery better at biological motion perception? We administered four experiments measuring sensitivity in using (global) form and (local) motion cues in biological motion, plus well-established ...

OBJECTIVES Mental imagery abnormalities occur across psychopathologies and are hypothesized to drive emotional difficulties in bipolar disorder (BD). A comprehensive assessment of mental imagery in BD is lacking. We aimed to test whether (i) mental imagery abnormalities (abnormalities in cognitive stages and subjective domains) occur in BD relative to non-clinical controls; and (ii) to determin...

in this study mercury was determined in canned tuna fish produced and distributed in iran after digestion by the standard methods of aoac. mercury contents in fish and canned tuna fish were determined by cold vapor atomic absorption spectrophotometry. the metal contents expressed in mg/kg wet weight for mercury varied from 0.017 to 0.394 (average of 0. 089) and 0.023 to 0.529 (average of 0.146)...

Elasmobranchs, the taxonomic group comprising sharks, skates and rays, play important roles in society and marine ecology but several species in this subclass are under threat.  This collection aims to be an open access hub for articles concerning all areas of elasmobranch biology and conservation. The collection is indefinitely open to further submissions and so will continue to grow as additi...

If you're even remotely up-to-date on your nutrition-for-health reading, you're well aware of the benefits of fish oil. Moreover, if you're anything like me, you've also gone to great lengths--often to no avail--to convince people that they should be taking it even if it does sound "icky." In an effort to save you and I a lot of future time and energy, I've compiled the following for you to sha...
