The present study assessed how the effects of perceptual load on distractibility in … WebUnder high perceptual load, fearful faces, but not contemptuous faces, elicited increased activity in frontal and temporal areas, and in the cerebellum. Interestingly, temporal and frontal activation was also modulated by coping style. Individuals with a disposition to cognitively avoid anxiety-inducing information showed decreased brain ...

The influence of schizotypal traits on attention under high perceptual load

WebPerceptual load is divided into three categories: low, moderate, and high. Driving without an urgent event, such as driving on an empty road, falls into the low perceptual load category.

WebHigh perceptual load in a task is known to reduce the visual perception of unattended items (e.g., Lavie, Beck, & Konstantinou, 2014). However, it remains an open question whether perceptual load in one modality (e.g., vision) can affect the detection of stimuli in another modality (e.g., hearing). WebFor example, high perceptual load (increased task demands) is associated with reduced interference (Lavie, 1995), as is a temporal separation between distractor and target (Kahneman, Treisman & Burkell, 1983;Watson & Humphreys, 1997) and the peripheral (compared with foveal) presentation of distractors (Beck & Lavie, 2005). WebJan 1, 2024 · There was no significant difference between low and high perceptual load conditions in terms of physical demand (z = − 1.94, p = 0.05, d = 0.33) and frustration ratings (z = − 0.94, p = 0.35, d = 0.16). These results provide further evidence that the chosen perceptual load task successfully created two distinct conditions. optometrist in spring hill tn

Weba high-load display invokes an early selection mode of attention. Lavie (1995) tested whether the ability to ignore dis-tractors in a choice response task could indeed be deter-mined by the perceptual load of the display.
