Differential Effects of Divided Attention on Object Representations
… two stages: a pre-attentive stage and a focused attention stage. It is during the focused attention stage that a representation of the perceived object is formed. Theories such as Object File Theory account for the maintenance of these object representations following their creation. Evidence for …

The influence of divided attention on directed forgetting
… Previous research suggests that dividing attention during List 2 learning eliminates DF thereby serving as a boundary condition for obtaining DF (e.g., Conway et al., 2000). This study re-examined this claim, and included additional conditions not previously employed in prior research. In …

The contribution of divided attention to tripping while walking
… tripping on seen obstacles) has received more attention. The primary aim of this research was to examine foot motion during long-term (e.g., 30 minutes) continuous treadmill walking by measuring minimum toe clearance (MTC), the very small distance the foot clears the ground during swing phase …

The Relationship Between Self-reported Chronic Stress And Divided Attention Performance
… examining the relationship with performance on divided attention tasks. Fifty-four university undergraduates, who self-reported a wide range of perceived chronic stress (10-item Perceived Stress Scale), completed the Trail-Making Test and a dual (auditory and visual) Continuous Performance Test …

The Effects of Task Preference on Speech and Motor Performance Under Divided Attention Conditions
… study, task preference was investigated under divided attention conditions in order to determine what effect preference had on task performance. Twenty young adults took part in this study and were randomly assigned into two groups. Each group was experimentally motivated to favor one of the …

Video game playing: its effects on divided attention, encoding and retrieval processes of human memory
Skills of divided attention are important to perform a multitude of tasks. However, there is a dearth of previous research that has investigated means to improve these skills. The present study investigated the use of video games as a training tool to enhance skills of divided attention, explored …

The Effects of Divided Attention on Speech Motor, Verbal Fluency and Manual Motor Task Performance
Research in dual task performance varies widely in its methodology and results. The present study employed three different types of activity to provide insights into the interference that occurs in dual task performance. Twenty young adults completed a speech task (repeating a sentence), a verbal …

A divided-attention timed stepping accuracy task as a procedural learning intervention improves balance and functional performance in healthy older adults
… can affect balance and functional outcomes. The divided-attention timed stepping accuracy task required participants to step to and from 16 targets in a random order as quickly and accurately as possible. The physical stepping task was performed simultaneously with a cognitive …

A DIMENSIONAL APPROACH TO ASSESSING ASPECTS OF ATTENTION AMONG CHILDREN WITH AND WITHOUT SYMPTOMS OF ATTENTION-DEFICIT/HYPERACTIVITY DISORDER AND/OR ANXIETY
… examined the relationship between parent-rated attention problems, anxiety, and hyperactivity/impulsivity symptoms and children’s performance on various attention domains, including selective, sustained, and divided attention and executive functioning, specifically related to set-shifting and …

The Effects of Distraction on Confidence Rating Reactivity During Cued-Recall
… reactivity patterns under conditions of full or divided attention. Compared to full attention, divided attention was expected to reduce test-based memory monitoring, thereby reducing or eliminating reactivity patterns relative to a no-CR control group. However, results showed no significant …

Cognitive training with casual video games: the effects of working memory and reasoning related games on the cognitive abilities of younger and older adults
… pre and post-training performance on tests of attention, episodic memory, perceptual speed, reasoning and working memory. Groups of younger (Baniqued et al., 2014) and older adults were trained with casual games that were correlated with working memory and reasoning abilities. Younger adults …

Investigations of the cognitive and neural processes supporting memory for neutral and emotional words
… detail, of information encoded. In Chapter 1, a divided attention paradigm was used to examine memory formation when resources are (a) devoted primarily to encoding and (b) directed away from encoding, and toward a secondary task. In condition (b) the memories formed often lacked vividness. The …

Conformal Flight Path Symbology for Head-Up Displays: Defining the Distribution of Visual Attention in Three-Dimensional Space
Theories of allocation of attention were used to interpret the experimental findings. Attention was found to be more widely distributed in X-Y space when the pilots were flying with the conformal, tunnel-in-the-sky as compared to the partially conformal ILS (instrument landing system) symbology …

Configural Displays: The effects of salience on multi-level data extraction
… displays are effective in supporting focus and divided attention tasks through the use of emergent features. Emergent features are highly salient and are generally used to support divided attention task However, due to the salience of emergent features, a potential performance costs to focused …

Effects of Brain Injury Severity and Effort on Neuropsychological Tests of Attention
Attention impairment is one of the most common complaints following Traumatic Brain Injury (TBI). Multiple studies have shown that performance on neuropsychological tests of attention is affected by many factors, including injury severity and effort. The aim of this study was to determine the …

Pain and Principle: The Effects of Nociceptive Stimuli on Moral Decision Making
… autonomic activation. This suggests that while divided attention or occupation of WM resources does effect patterns of moral decision making, this is not reliant on a nociceptive stimulus.

The Differential Effects of Mental Fatigue and Alcohol on Selective Attention
Decrements in selective attention are a commonly experienced phenomenon that has practical implications for many industries. Two causes of such deficits are mental fatigue and alcohol intoxication, which impair selective attention by decreasing the efficiency of inhibitory processes. The present …

Sleep inertia and alcohol impairment in young adults: neurocognitive effects and interactions Implications for fire escape behaviours
… working memory and sustained, selective, and divided attention functions were assessed for performance decrements and reference to speed-accuracy trade-off effects. Participants were 24 young adults (18-26 years) who participated in a repeated-measures study over 2 nonconsecutive nights; 1 …

Investigating the Effect of Attentional Control on Source Monitoring and DRM Memory Performance
… DRM paradigms have highlighted the importance of attentional control (AC), with divided attention (DA) during encoding leading to impaired source detail recollection. This thesis examined how AC affected the accuracy of source monitoring and susceptibility to false memories based on list type. …

Implementation of an attention training program with children with attention deficit hyperactivity disorder in South Africa
Attention Deficit/Hyperactivity Disorder (ADHD) is a group of behavioural symptoms that include inattentiveness, hyperactivity and impulsiveness and tends to be the most commonly diagnosed childhood behavioural disorder. The aim of this study was to determine the feasibility of the Pay Attention! …
