The Attentional Blink
0 Views •
2023
Source: Laboratory of Jonathan Flombaum—Johns Hopkins University In order for recognition of a certain stimulus to take place, visual attention needs to be directed towards said stimulus. To the earliest parts of the visual system, objects are not objects, they are collections of visual features-lines, corners, changes in texture, color, and light. Attention is the resource that is necessary for later processing in order to recognize what a given bundle of features adds up to. This makes...

A Dual Task Procedure Combined with Rapid Serial Visual Presentation to Test Attentional Blink for Nontargets

This paper describes a novel dual task procedure combined with Rapid Serial Visual Presentation to look at attentional blink at varied stimulus onset asynchronies. This experimental procedure differed from others in that it tested attentional blink for nontargets.

Tip-of-the-Tongue Phenomenon

2025
The tip-of-the-tongue (TOT) phenomenon is a cognitive experience characterized by a temporary inability to retrieve specific information from memory despite having a strong feeling of knowing the information. Although individuals cannot access the target word or detail, they frequently recall related elements, such as its initial letter, syllable count, or context. This partial retrieval often causes frustration, as one might recognize a familiar face or know that a name starts with a specific...

Measurement of Neurophysiological Signals of Ignoring and Attending Processes in Attention Control

Attention control comprises enhancement of target signals and attenuation of distractor signals. We describe an approach to measure separately but concurrently, the neurophysiology of attending and ignoring in sustained intermodal attention, utilizing a passive control condition during which neither process is continuously engaged.

Visual Attention: fMRI Investigation of Object-based Attentional Control

Source: Laboratories of Jonas T. Kaplan and Sarah I. Gimbel— University of Southern California The human visual system is incredibly sophisticated and capable of processing large amounts of information very quickly. However, the brain's capacity to process information is not an unlimited resource. Attention, the ability to selectively process information that is relevant to current goals and to ignore information that is not, is therefore an essential part of visual perception. Some aspects of...
FAQs
The first target does more than capture visual attention: identifying it engages working memory and response-selection processes. These operations temporarily occupy resources needed to process another target, reducing the likelihood that the second item will be detected when it arrives soon afterward. This makes the phenomenon useful for examining how attention and cognition interact over time.
The attentional blink is especially associated with a second target appearing roughly 200–500 milliseconds after the first. This interval identifies a period in which processing the initial target leaves fewer attentional resources available. Varying the temporal separation between targets therefore helps researchers examine how quickly attention can support successive visual events.
It demonstrates that seeing a visual event does not guarantee that a nearby event will also reach awareness or be identified. By showing reduced access to a second target during rapid processing, the effect provides evidence about limits in temporal attention, visual awareness, and information processing. These findings also contribute to broader models of cognition.
Researchers commonly present visual items in rapid serial visual presentation, a sequence in which stimuli appear one after another at high speed. Participants identify a first target and attempt to detect a second target presented soon afterward. Researchers then examine second-target detection in relation to its timing after the first target.
A missed second target can indicate that processing the first target temporarily consumed resources needed for subsequent identification. The result is interpreted within the timing of the sequence rather than as a general inability to see visual information. Across trials, this pattern helps researchers study temporal limits on attention and response selection.
Fast-moving environments may present important visual events in close succession, creating conditions in which one event receives processing priority and a later event is missed. Studying the attentional blink helps explain this vulnerability in driving, monitoring, and digital interfaces. The phenomenon therefore connects laboratory research on temporal attention with situations requiring rapid visual awareness.
