This human neuroimaging review aims to determine the degree to which visual memory evokes activity in neural regions that have been associated with visual perception. A visual perception framework is proposed to identify cortical regions associated with modality-specific processing (i.e., visual, auditory, motor, or olfactory), visual domain-specific processing (i.e., "what" versus "where," or ...

Visual working memory plays a central role in most models of visual search. However, a recent study showed that search efficiency was not impaired when working memory was filled to capacity by a concurrent object memory task (Woodman, Vogel, & Luck, 2001). Objects and locations may be stored in separate working memory subsystems, and it is plausible that visual search relies on the spatial subs...

there are strong relationship and common neural mechanism between working memory, short term storage, executive attention and fluid intelligence.  therefore we can consider these constructs as integrated construct as fluid cognition. to verify this claim, we implemented forward and backward digit and letter spam, visual memory spam. counting spam, stroop, wisconsin card, keep track and cattle i...

In her Multiple-Entry, Modular Memory (MEM) model on human cognition, Marcia Johnson differentiated perceptual subsystems that interact directly with the external environment and reflective subsystems that operate in the absence of external input (Johnson, 1992). Visual memory is an example of processes that are situated at the border between these two. Short-term visual memory directly bridges...

How much visual information can we hold in mind at once? A large body of research has attempted to quantify the capacity of visual working memory by focusing on how many individual objects or visual features can be actively maintained in memory. This thesis presents a novel theoretical framework for understanding working memory capacity, suggesting that our memory representations are complex an...

Previous research has shown a systematic relationship between phonological working memory capacity and second language proficiency for alphabetic languages. However, little is known about the impact of working memory processes on second language learning in a non-alphabetic language such as Mandarin Chinese. Due to the greater complexity of the Chinese writing system we expect that visual worki...

Brain-derived neurotrophic factor (BDNF) is involved in numerous cognitive functions including learning and memory. BDNF plays an important role in synaptic plasticity in humans and rats with BDNF shown to be essential for the formation of long-term memories. We previously identified a significant association between the BDNF Val66Met polymorphism (rs6265) and long-term visual memory (p-value =...
