Elastic Attention: Enhanced, then Sharpened Response to Auditory Input as Attentional Load Increases

A long debate in selective attention research is whether attention enhances sensory response or sharpens neural tuning by suppressing response to non-target input. In fact, both processes may occur as a function of load: an uncertain listener might use a broad attentional filter to enhance responses to all inputs (i.e., vigilance), yet employ sharpened tuning to focus on hard to discriminate ta...

Attention Response Functions Characterizing Brain Areas Using fMRI Activation during Parametric Variations of Attentional Load

We derived attention response functions for different cortical areas by plotting neural activity (measured by fMRI) as a function of attentional load in a visual tracking task. In many parietal and frontal cortical areas, activation increased with load over the entire range of loads tested, suggesting that these areas are directly involved in attentional processes. However, in other areas (FEF ...

Attentional Load Increases the Positivity of Self - Presentation

Recent research has addressed the role of attention in self-presentation. The present study examined the effects of allentional load on the positivity of selfdescriptions. Subjects rated themselves on 30 traits presented on a microcomputer. To create an allentionalload, we required subjects to monitor digits that appeared regularly on the screen. To manipulate the load, we varied the speed of d...

The strength of attentional biases reduces as visual short-term memory load increases.

Despite our visual system receiving irrelevant input that competes with task-relevant signals, we are able to pursue our perceptual goals. Attention enhances our visual processing by biasing the processing of the input that is relevant to the task at hand. The top-down signals enabling these biases are therefore important for regulating lower level sensory mechanisms. In three experiments, we e...

Auditory Working Memory Load Impairs Visual Ventral Stream Processing: Toward a Unified Model of Attentional Load

Attentional interference between tasks performed in parallel is known to have strong and often undesired effects. As yet, however, the mechanisms by which interference operates remain elusive. A better knowledge of these processes may facilitate our understanding of the effects of attention on human performance and the debilitating consequences that disruptions to attention can have. According ...
