Conceptual illustration of how a verbal description such as “red car” could be projected through a generative hierarchical model to create a noisy visual instantiation.
An illustration showing one possible compositional visual representation of a car including its components, its overall shape, and the most prominent color. In our framework, a memory representation could access some combination of any or all of these depending on the task.
Illustration of the hypothesized flows of information between perception, memory and cognitive control in a conceptual model of working memory. Stimuli attributes are processed to varying degrees of abstraction and parts of these representations can be loaded into working memory under the guidance of cognitive control. Familiar stimuli such as the letter B activate visually abstract representations while less familiar stimuli are limited to sensory representations. Information can be shifted both up and down levels of the perceptual hierarchy to build either more or less abstract representations of either perceived or imagined stimuli. Working memories can be shifted into or out of the hierarchy as needed.

Line graph showing how each of the 4 passage lengths (10,20,30,50 words) were recalled at each level of approximation (0,1,2,3,4,5,7,text). Accuracy increases steadily as the list of words gets shorter, and also increases as the approximation gets closer to text. However it hits a ceiling at the 5th level and does improve beyond that point.. It's just flat across 5,7 and text

A poster that reads: "The attentional blink? More like the attentional myth. Brad Wyble wants you to believe your brain blinks and forgets the second target... But what if that's just bad science in disguise? Correlation isn't causation: Just because T2 drops in accuracy doesn't mean there's a blink, it could be interference, expectation or task design flaws. Alternative models exist: Have you head of the boost and bounce theory or object updating models? Brad conveniently doesn't mention them when pushing the blink. Cherry-picked data? Manyi AB studies rely on RSVP tasks that create the blink effect. real-world attention doesn't work in PowerPoint slides. Stop Blinking. Start Thinking. It's time to leave the Blink behind and demand a better model
Google search results for the attentional blink presents this summary "The attentional blink (AB) is a temporary inability to recognize a second target that appears very shortly after the first. It's a result of the brain's limited capacity to process information. How it happens The brain is processing information from the first target The second target appears too soon for the brain to process it The brain is unable to allocate enough resources to process both targets How it's studied The AB paradigm presents stimuli like letters, numbers, or pictures in rapid succession Participants are asked to report if they saw the second target Real-world consequences The AB can have serious consequences in real-world situations, like when a driver is unable to notice a deer in the road Related concepts Repetition blindness: The difficulty of recognizing a second target that is the same as the first in a rapid serial visual presentation task"

Text from Google's AI Gemini that reads "A resting heart rate of 100 beats per minute is considered "normal" for most adults, as a typical resting heart rate falls within the range of 60-100 beats per minute; however, if your resting heart rate consistently stays at or above 100, it could indicate a condition called tachycardia and you should consult a doctor to investigate potential causes"
