Attentional blink
Attentional Blink
Attentional blink (pronunciation: /əˈtenʃənəl blɪŋk/) is a psychological term that refers to the phenomenon where a person fails to recognize a second stimulus that follows closely after the first one. This phenomenon is often observed in rapid serial visual presentation (RSVP) tasks.
Etymology
The term "attentional blink" was coined by psychologists Raymond, Shapiro, and Arnell in 1992. The term is derived from the English words "attention" and "blink", metaphorically suggesting a momentary lapse or "blink" in attention.
Definition
In the field of Psychology, attentional blink refers to a period of time when the brain is unable to process a second or subsequent stimuli if they are presented in close temporal proximity to the first stimulus. This typically occurs for stimuli presented between 200-500 milliseconds after the first stimulus.
Related Terms
- Rapid Serial Visual Presentation (RSVP): A method used in cognitive research to present stimuli in quick succession.
- Temporal Resolution: The ability of the sensory system to perceive changes in a stimulus over time.
- Visual Perception: The ability to interpret the surrounding environment using light in the visible spectrum reflected by the objects in the environment.
Research
Research on attentional blink has implications for understanding the limitations of human attention and perception. It has been used to study various aspects of cognition, including the speed of information processing, the role of attention in perception, and the mechanisms underlying temporal integration.
