Mental training affects distribution of limited brain resources. (1/71)

The information processing capacity of the human mind is limited, as is evidenced by the so-called "attentional-blink" deficit: When two targets (T1 and T2) embedded in a rapid stream of events are presented in close temporal proximity, the second target is often not seen. This deficit is believed to result from competition between the two targets for limited attentional resources. Here we show, using performance in an attentional-blink task and scalp-recorded brain potentials, that meditation, or mental training, affects the distribution of limited brain resources. Three months of intensive mental training resulted in a smaller attentional blink and reduced brain-resource allocation to the first target, as reflected by a smaller T1-elicited P3b, a brain-potential index of resource allocation. Furthermore, those individuals that showed the largest decrease in brain-resource allocation to T1 generally showed the greatest reduction in attentional-blink size. These observations provide novel support for the view that the ability to accurately identify T2 depends upon the efficient deployment of resources to T1. The results also demonstrate that mental training can result in increased control over the distribution of limited brain resources. Our study supports the idea that plasticity in brain and mental function exists throughout life and illustrates the usefulness of systematic mental training in the study of the human mind.  (+info)

Enhanced identification of smoking-related words during the attentional blink in smokers. (2/71)

The attentional blink (AB) occurs when ongoing processing of one target (T1) in a series of rapidly presented stimuli impairs processing of a subsequently presented second target (T2), such that T2 cannot be consciously perceived or reported. There is evidence that the AB can be influenced by the emotional or motivational salience of T2. We examined whether the AB could be attenuated by smoking-related stimuli in smokers. Heavy smokers (N=55) performed an AB task on two occasions, once following 12-h of abstinence and once following ad libitum smoking. T2s were either smoking-related or neutral (household-related) words, and lagged T1 by 0 to 7 distracter words. T1s were all neutral words. Each word was presented for 130 ms. Subjects were required to recall T1 and T2 immediately after each trial. There was a significant word type by lag interaction, whereby smoking-related T2s were recalled better than neutral T2s at early, but not late, lags. The word type effect at early lags was significantly associated with attentional bias assessed on the smoking Stroop task, but was not significantly moderated by abstinence. These data indicate that, in heavy smokers, smoking-related stimuli are more likely to engage conscious awareness than neutral words under conditions of limited attentional resources.  (+info)

Attentional blinks as errors in temporal binding. (3/71)

In the attentional blink [Raymond, J. E., Shapiro, K. L., & Arnell, K. M. (1992). Temporary suppression of visual processing in an RSVP task: An attentional blink? Journal of Experimental Psychology: Human Perception and Performance, 18(3), 849-860.], the second of two targets in a Rapid Serial Visual Presentation (RSVP) stream is difficult to detect and identify when it is presented soon but not immediately after the first target. We varied the Stimulus Onset Asynchrony (SOA) of the items in the stream and the color of the targets (red from gray or vice versa), and looked at the responses to the second target. Exact responses to the second target (zero positional error) showed a typical attentional blink profile, with a drop in performance for an interval of 200-500 ms after the first target. Approximate responses (positional error no greater than 3 frames) showed no such drop in performance, although results were still dependent on color (better for red) and increased with increasing SOA. These findings are consistent with a two-stage model of visual working memory, where encoding of the first target disrupts attention to (and temporal binding of) the second target. We suggest that this disruption occurs within a certain time (approximately 0.5 s) after the first target, during which period salient distractors are as likely as the second target to enter working memory.  (+info)

The blinking spotlight of attention. (4/71)

Increasing evidence suggests that attention can concurrently select multiple locations; yet it is not clear whether this ability relies on continuous allocation of attention to the different targets (a "parallel" strategy) or whether attention switches rapidly between the targets (a periodic "sampling" strategy). Here, we propose a method to distinguish between these two alternatives. The human psychometric function for detection of a single target as a function of its duration can be used to predict the corresponding function for two or more attended targets. Importantly, the predicted curves differ, depending on whether a parallel or sampling strategy is assumed. For a challenging detection task, we found that human performance was best reflected by a sampling model, indicating that multiple items of interest were processed in series at a rate of approximately seven items per second. Surprisingly, the data suggested that attention operated in this periodic regime, even when it was focused on a single target. That is, attention might rely on an intrinsically periodic process.  (+info)

Noradrenergic neuromodulation of human attention for emotional and neutral stimuli. (5/71)

INTRODUCTION: Norepinephrine (NE) has a regulatory role in human attention. OBJECTIVE: To examine its role in emotional modulation of attention, we used an attentional blink (AB) paradigm, in the context of psychopharmacological manipulation, where targets were either emotional or neutral items. RESULTS AND DISCUSSION: We report behavioural evidence that beta-adrenergic blockade with propranolol impairs attention independent of target valence. Furthermore, this effect is centrally mediated as administration of the peripheral beta-adrenergic antagonist nadolol did not impair attention. By contrast, increasing NE tone, using the selective NE reuptake inhibitor reboxetine, improves detection of emotional stimuli. CONCLUSION: In line with theoretical and animal models, these findings provide human behavioural evidence that the adrenergic system has a modulatory influence on selective attention that in some instances depends on item valence.  (+info)

Attentional blink (AB) is a phenomenon that reflects the temporal costs in the allocating selective attention. The AB is typically measured by using rapid serial visual presentation (RSVP) tasks, where participants often fail to detect a second salient target occurring in succession if it is presented between 180-450 ms after the first one. Also, the AB has been observed using two backward-masked targets and auditory stimuli. The term attentional blink was first used in 1992, although the phenomenon was probably known before. The precise adaptive significance behind the attentional blink is unknown, but it is thought to be a product of a two-stage visual processing system attempting to allocate episodic context to targets. In this two-stage system, all stimuli are processed to some extent by an initial parallel stage, and only salient ones are selected for in-depth processing, in order to make optimum use of limited resources at a late serial stage. One curious aspect of attentional blink is ...
North Korea has warned Japan that Tokyo would be the first target in the event of a war on the Korean Peninsula, as it increased threats of an attack.
Various psychophysical techniques have been proven successful tools to render visual inputs subjectively invisible. For example, backward masking obstructs the awareness of a prior stimulus, and the masked stimulus remains invisible even with full attention at the correct spatiotemporal location. In contrast, observers would miss the presence of a strong stimulus if their attention were not directed to the stimulus. These two examples both demonstrate observers failure to detect a stimulus. However, it remains unknown whether the nature of unawareness between those techniques is the same. Here we developed a method for classifying different types of psychophysical blinding techniques such as in current study, backward masking and attentional blink (AB). In experiment 1, we impaired the visibility of a target luminance blob by presenting a mask immediately after. The observers detection accuracy deteriorated as a function of ISI between the target and the mask. In experiment 2, we used AB to ...
Weve discussed attentional blink several times on CogDaily. Its a fascinating phenomenon: if you see a series of images flashing by rapidly, you can normally pick out one of the images (for example, a banana in series of pictures of familiar objects). But if a second such image (another piece of fruit, like an apple) appears shortly after the first, youll probably miss it. The one exception in many cases is faces. This video illustrates the point:. Click here to play the movie. You probably spotted both the piece of fruit and the face in the second sequence, but you may have missed the watch in the first sequence.. The first sequence is a classic attentional blink: If the second image they are looking for flashes between 200 and 400 milliseconds after the first, people dont seem to notice it. Its as if theres a literal blink in our attention to the pictures. While faces have some immunity to attentional blink, that immunity can be overcome if both of the pictures being searched for are ...

The first target of antimicrobial peptides (AMPs) is the bacterial membrane. In the case of Gram-negative bacteria this is the outer membrane (OM), the lipid composition of which is extremely asymmetric: Whereas the inner leaflet is composed of a phospholipid mixture, the outer leaflet is made up solely from lipopolysaccharides (LPSs). LPS, therefore, represents the first target of AMPs. The binding and intercalation of polycationic AMPs is driven by the number and position of negatively charged groups of the LPS. Also, proteins other than cationic AMPs can interact with LPS, e.g. leading eventually to a neutralization of the endotoxic effects of LPS. We compared different biophysical techniques to gain insight into the properties of the electrical surface potentials of lipid monolayers and aggregates composed of LPSs and various phospholipids and their interaction with peptides and proteins. The net negative charge calculated from the chemical structure of the phospholipid and LPS molecules is linearly
It is a rare thing indeed for me to visit a park and actually be less interested in the coasters than the other attractions, but Sea Paradise was one such place. The park had caught my imagination from the day I first heard about Blue Fall, an absolutely enormous giant drop ride, stretching some 351ft into the air. This put it head and shoulders above any other such ride I had tried, and with wristband in place it was my first target. Ascending the tower is an experience in itself. On more than one occasion I was absolutely convinced that we must have reached the top, but no, the ascent kept on going. Disappointment set in when I realised that the ride had a countdown at the top, but it was soon forgotten after the mechanism released and we fell about ten feet, paused briefly, and then fell the remaining distance.. Falling from that height was an incredible rush, marred only by some very serious vibration towards the bottom of the tower. This is a new one to me; a ride that only goes up and down ...

SAMUEL H. SHAPIRO was born Israel Shapiro in Estonia and immigrated to the United States at a young age. After graduating from the University of Illinois College of Law, he practiced in Kankakee. He went on to win election as states attorney (county prosecutor) of Kankakee County. He was also a member of the Illinois House of Representatives from 1947 to 1961.Shapiro was elected Lieutenant Governor in 1960 and reelected in 1964. He became governor when Otto Kerner Jr. resigned to accept appointment to the federal appellate court. In 1968, Shapiro ran for election to a full term of his own but was narrowly defeated by his Republican opponent, Richard Ogilvie. An alumnus of the Alpha Epsilon Pi fraternity, Shapiro led the effort to establish a permanent headquarters for the fraternitys national offices.

A range of techniques has been used to probe non-spatial or non-directional deficits. The attentional blink paradigm has revealed a profound and long-lasting deficit in the temporal dynamics of visual processing for stimuli presented at fixation in right-hemisphere neglect patients (Husain et al., 1997). When attention is engaged on one item, such patients have difficulty in attending to subsequent items for ,1 second, even when items are presented centrally, a finding reminiscent of non-spatial extinction in parietal patients (Humpreys et al. 1994). Bilateral deficits (i.e. on both sides of space) have also been reported in parietal patients, with reduced capacity to encode visual stimuli presented transiently in either visual field (Duncan et al., 1999; Batelli et al., 2001). Several groups have also reported impaired ability to sustain attention or maintain vigilance over protracted periods of time in patients with neglect, even for central auditory stimuli (see Robertson, 2001). Others have ...

A multi-density polymeric interbody spacer formed from biocompatible material for osteoconductivity includes multiple density regions of different porosity to provide both strength and osteoconductivity. An interface region is formed between the density regions to provide both direct adhesion and mechanical interlocking between the different density regions to increase the strength of the multi-density polymeric interbody spacer. A method for forming the multi-density polymeric interbody spacer includes curing a first density region to achieve a first target porosity. A second density region may then be molded to the first density region to achieve a second target porosity. A portion of the second density region partially flows into pores of the first density region, providing direct adhesion and mechanical interlocking between the first and second density regions.
TY - JOUR. T1 - The effect of temporal asynchrony on the multisensory integration of letters and speech sounds. AU - van Atteveldt, N.M.. AU - Formisano, E.. AU - Blomert, L.P.M.. AU - Goebel, R.W.. PY - 2007/1/1. Y1 - 2007/1/1. N2 - Temporal proximity is a critical determinant for cross-modal integration by multisensory neurons. Information content may serve as an additional binding factor for more complex or less natural multisensory information. Letters and speech sounds, which form the basis of literacy acquisition, are not naturally related but associated through explicit learning. We investigated the relative importance of temporal proximity and information content on the integration of letters and speech sounds by manipulating both factors within the same functional magnetic resonance imaging (fMRI) design. The results reveal significant interactions between temporal proximity and content congruency in anterior and posterior auditory association cortex, indicating that temporal synchrony ...
