Visual long-term memory has weaker fidelity than working memory

چکیده
Recent research suggests that visual long-term memory (VLTM) and visual working memory (VWM) possess similar resolution for feature memory. We investigated resolution in more holistic terms, exploiting a two alternative forced choice (2AFC) procedure and injecting noise into stimuli. Participants were exposed to two real-world objects per trial in a VWM experiment. One object was tested after a short delay. The other object (from each trial) was tested in a later session. We observed better performance for VWM, and the two systems were affected by noise in distinct ways. These results have broad implications for theories of visual memory.

Visual long-term memory has the same limit on fidelity as visual working memory.
Visual long-term memory can store thousands of objects with surprising visual detail, but just how detailed are these representations, and how can one quantify this fidelity? Using the property of color as a case study, we estimated the precision of visual information in long-term memory, and compared this with the precision of the same information in working memory. Observers were shown real-w...

متن کاملThe Effect of Working Memory Rehabilitation on Visual Memory and Memory Span
Introduction: Age-related cognitive decline or cognitive aging is largely the result of structural and functional decline in specific areas of the brain, but lifestyle also contributes to this cognitive decline. The aim of this study was to investigate the effect of working memory rehabilitation on visual memory and memory span in ageing. Methods: This was a quasi-experimental study with pret...
متن کاملTime Course of Fidelity and Contributing Factors to Long-Term Memory
Various models have been implemented to explain long-term memory (Brady, et al., 2013; Lew, et al., 2015), with some being derived from studies of visual working memory (Bays, et al. 2009; Zhang & Luck, 2008). The implicit assumption is that processes and mechanisms of working memory also exist in long-term memory. However, the findings of fidelity and contributing factors are highly varied (e....
