Demand Transitions and Sustained Attention

The Journal of General Psychology, 1993
A recent report by the National Research Council (Huey & Wickens, 1993) has identified transitions in task demand as an important dimension for study in vigilance research. This experiment tested the possibility that the effects of such transitions follow a relatively simple psychophysical rule--they are characterized by contrast effects.

Attenuation of spatial attentional asymmetries with poor sustained attention

NeuroReport, 2004
The co-existence of deficits in sustained and spatial attention in patients with acquired damage to the right cerebral hemisphere has led to the proposition that sustained attention could be a marker for left spatial inattention, or neglect. We investigated the possibility that reductions in leftward spatial attentional asymmetries could arise from ...

Sustained Attention in Major Unipolar Depression

Perceptual and Motor Skills, 2007
Patients suffering from a major unipolar depression ( n = 17) and a normal control group ( n = 17) were compared on a noninterrupted vigilance task with a duration of 36 min. The performance decrement over time of the depressed group was indicative of a deficit in sustained attention.

Sustained Attention in Methadone Patients

International Journal of the Addictions, 1982
Sustained attention was examined in chronic, high-dose (70-120 mg) methadone patients with a modified Continuous Performance Test (Rosvold et al., 1956) 45 min in duration. Working and nonworking patient groups, and drug-free ex-addict and opiate-naive comparison groups were tested at high, moderate, and low signal rates.

Sustained attention and intelligence

Intelligence, 1990
Abstract The sustained attention of retarded and nonretarded adults was assessed during two 60-min vigilance tests that differed in memory demand. Subjects compared visually presented digit sets that were separated by 3 or 6 s; consecutive matching digit sets served as the target event.

Schizotypy and sustained attention.

Journal of Abnormal Psychology, 1991
We examined sustained attention in 32 schizotypic and 43 normal control subjects from a large, randomly ascertained nonclinical university population. Schizotypy status was determined with the Perceptual Aberration Scale. Sustained attention was measured with the Continuous Performance Test-Identical Pairs.

The Sustained Attention Test: a measure of attentional disturbance

Computers in Human Behavior, 1998
Abstract The Sustained Attention Test is a vigilance task designed to assess the ability of individuals with schizophrenia to sustain attention to visual stimuli. The task requires the subject to attend to two vertically adjacent squares on a computer monitor. Each square changes color at random intervals.

Sustained investor attention

Prior research on investor attention focuses primarily on whether investors access disclosures rather than how long they engage with them. We examine this latter dimension—sustained investor attention—using proprietary data from Quartr that allow us to measure how long investors listen to earnings conference calls.

Focused and Sustained Attention

2013
The selection of stimuli and responses for cognitive processing is an essential element of attention. As we have discussed in the preceding chapters, the processes underlying selective attention has been a primary emphasis. Yet, as the cognitive science of attention evolved, it became evident that it was necessary to account for other important aspects

Generating and Sustaining Attention

2009
A few years ago I would announce in my motivation classes that the study of curiosity had been neglected in the educational and psychological literature. But, that seems to have changed! Maybe it’s because of the re-emergence of interest in multimedia, increased concerns about decreases in invention and patent applications in our society, or just ...
