Models of sustained attention

Current Opinion in Psychology, 2019
Attention is not constant, but fluctuates from moment-to-moment. Multiple neurocognitive factors contribute to these fluctuations, acting to help us get 'in the zone' as well as pulling us away from this optimal and fleeting state. Models of arousal, mind wandering, cognitive resource allocation, and effort have consequences for this fundamental ...

Sustained Attention and Pervasive Hyperactivity

Journal of Child Psychology and Psychiatry, 1991
Abstract A sustained attention deficit is defined as a significant decrement in task performance with task duration (time‐on‐task). Time‐on‐task effects are reported using a self‐paced paper and pencil cancellation test (PPCT) in normals and in subgroups of pervasively hyperactive children.

Sustained attention and the experience of flow

Psychological Research, 2020
The state of flow-often referred to as being "in the zone"-is characterized by the experience of deep, effortless concentration on the activity one is engaged in. While much of the flow literature seems to imply a tight link between flow and attention processes, relatively little work has assessed this question empirically.

Effects of goal-setting on sustained attention and attention lapses

Attention, Perception, & Psychophysics, 2023
In three experiments, we examined the effects of goal-setting on sustained attention and attention lapses. We measured both behavioral task performance and subjective attentional states during a four -choice reaction time task (Experiments 1 and 2 administered online; Experiment 3 conducted in-person).

The multiple dimensions of sustained attention

Cortex, 2008
Sustained counting (or temporal numerosity judgements) has been one of the key means of investigating anterior attentional processes. Forty-three patients with localised lesions to the frontal lobes were assessed on two tests of the ability to count the number (8-22) of stimuli presented at either a slow (roughly one per 3 sec) or fast (roughly three ...

Sustained Attention and Grade Retention

Perceptual and Motor Skills, 1994
Two studies are reported which explore the possible relationship between academic failure, as measured by grade retention, and the capacity to sustain attention on a computerized continuous performance task. In a nonreferred sample, 89 children who had been retained at some point in their academic careers showed a higher frequency of abnormal scores on

Sustained division of the attentional spotlight

Nature, 2003
By voluntarily directing attention to a specific region of a visual scene, we can improve our perception of stimuli at that location. This ability to focus attention upon specific zones of the visual field has been described metaphorically as a moveable spotlight or zoom lens that facilitates the processing of stimuli within its 'beam'. A long-standing

Sustained attention in children with autism

Journal of Autism and Developmental Disorders, 1990
Although many children with early infantile autism cannot maintain attention to externally imposed tasks, they may continue a repetitive behavior of their own choosing for long periods of time. This study examined the performance of autistic and mental age matched normal children on a Continuous Performance Test of sustained attention.

Frontal lesions and sustained attention

Neuropsychologia, 1987
Neurological patients were presented with a succession of 2-11 stimuli which they were required to count, reporting the number in the series when it finished. The stimuli were binaural clicks, or pulses on the right or on the left index finger. Regardless of stimulus modality or lateralization, patients with lesions involving the right frontal lobe ...

Sustained Attention in Remitted Schizophrenics

Archives of General Psychiatry, 1973
Sixteen drug-free discharged remitted schizophrenics and twenty control subjects were tested on the Continuous Performance Test (CPT), a test of sustained attention. Following baseline testing, a distraction condition consisting of auditory and visual distractors was introduced.
