Visual short-term memory load strengthens selective attention.
Perceptual load theory accounts for many attentional phenomena; however, its mechanism remains elusive because it invokes underspecified attentional resources. Recent dual-task evidence has revealed that a concurrent visual short-term memory (VSTM) load slows visual search and reduces contrast sensitivity, but it is unknown whether a VSTM load also constricts attention in a canonical perceptual...
متن کاملAttention and short-term memory: crossroads.
Selective attention and short-termmemory are staple, core psyhological constructs, which have been investigated from the first mpirical steps of our discipline (Ebbinghaus, 1885; Helmholtz, 867/1924). Everyone agrees they are intimately connected, but etting their boundaries and mapping their interrelationships emains challenging. This special issue of Neuropsychologia is ntended to provide a c...
متن کاملAttention gating in short-term visual memory.
Subjects first detected a target embedded in a stream of letters presented at the left of fixation and then, as quickly as possible, shifted their attention to a stream of numerals at the right of fixation. They attempted to report, in order, the four earliest occurring numerals after the target. Numerals appeared at rates of 4.6, 6.9, 9.2, and 13.4/s. Scaling analyses were made of(a) item scor...
متن کاملThe attention-weighted sample-size model of visual short-term memory: Attention capture predicts resource allocation and memory load
We investigated the capacity of visual short-term memory (VSTM) in a phase discrimination task that required judgments about the configural relations between pairs of black and white features. Sewell et al. (2014) previously showed that VSTM capacity in an orientation discrimination task was well described by a sample-size model, which views VSTM as a resource comprised of a finite number of no...
متن کاملL-carnosine Improves Short-Term Spatial Recognition Memory and Passive Avoidance Learning and Memory in Streptozotocin-Diabetic Rats
Background and Objective: Diabetes mellitus (DM) affects synaptic plasticity in the hippocampus, leading to impairments in learning and memory. L-carnosine, an endogenous dipeptide, is reported to exhibit anti-diabetic and antioxidant effects. Therefore, this study was designed to evaluate its effect on learning and memory in diabetic rats. Materials and Methods: In the present study, male Wis...
