Aerobic fitness and the attentional blink in preadolescent children
… neuroelectric and behavioral measures under the attentional blink task to examine this relationship. Using a cross-sectional design, response accuracy and event-related brain potentials were assessed for preadolescent children with different levels of aerobic fitness. Results indicated that …

The Effects of Video Games and Age on Attentional Blink Magnitude
… video games (AVGs) has been linked to improved attentional functioning. The present study examined whether age and AVG experience were associated with differences in the attentional blink (AB). This 2x2 cross-sectional study assigned participants (N = 25) to four groups based on their age and …

An electrophysiological investigation into the influence of affect on the attentional blink
… 500 ms of the first target (TI) - an attentional blink (AB). Affect has previously been shown to influence the magnitude of the AB such that positive affect (PA) is associated with smaller ABs. To account for these findings, Olivers and Nieuwenhuis (2005) proposed an overinvestment …

An Electrophysiological Investigation into the Role of Cognitive Control in the Attentional Blink
… 500 ms of the first target (T1) – an attentional blink (AB). Early models explained the AB in terms of attentional limitations creating a processing bottleneck such that T2 processing would be impaired while T1 processing was ongoing. Theoretical models of the AB have more recently …

Non-Target Emotional Stimuli Must Be Highly Conspicuous in Order to Break through the Attentional Blink
In the attentional blink (AB), the second of two targets (T2) separated by a short lag in a rapid serial visual presentation (RSVP) stream is difficult to report. The AB is typically thought of as a top-down effect because it is triggered when the first target (T1) matches a search template. …

The Impact of a Single Session of Mindfulness Meditation on the Attentional Blink in Non-Meditators
<p>Attentional resources are limited therefore a stimulus can go undetected if it closely follows another target by 200-500ms. This phenomenon is known as the attentional blink. Mindfulness meditation has been shown to be beneficial in target detection and in decreasing the attentional blink. Since …

Dual-Task Attentional Limitations in Anxiety: Examined with the Attentional Blink Paradigm and the Beck Anxiety Inventory
… knowledge about anxiety when examined with the Attentional Blink (AB) paradigm. It was believed that an increase in anxiety would lead to an increase in the ABs. Due to high comorbidity of anxiety and depression, both constructs were measured and hypotheses were formulated to predict if the …

SURPRISE-INDUCED DEAFNESS -- TEMPORAL CHARACTERISTICS OF A STIMULUS-DRIVEN LIMITATION IN AUDITORY SELECTIVE ATTENTION
… onto goal-directed limitation – i.e., auditory attentional blink or AAB. The result suggested that SiD indeed taps onto the stimulus-driven limitation in auditory selective attention.

Pulsed out of awareness: EEG alpha oscillations represent a pulsed inhibition of ongoing cortical processing
… for many common cognitive phenomena, such as the attentional blink, and seems to indicate that our visual experience may at least some times be coming through in waves. Chapter 1 contains a review of evidence that 8-12 Hz oscillations in the brain have a general inhibitory role in cognitive …

The effects of mindfulness meditation on attention regulation
… Network Test (ANT), or a reduction in the attentional blink (AB) effect, measured using a Rapid Serial Visual Presentation (RSVP) task. Chapter 1 reviews the relevant literature. Chapters 2 and 3 report five experiments which tested the effects of Focused Attention Meditation (FAM) on the …

Spatial and temporal processing biases in visual working memory in specific anxiety
… anxiety. Moreover, a temporal VWM paradigm - an attentional blink task - was applied to assess whether a biased encoding of spider images in spider fearfuls would occur at the expense of non-threatening items undergoing concurrent processing, and whether this effect was specific to spiders, but …
