A horizontal–vertical anisotropy in spatial short-term memory

نویسندگان

چکیده

Visual perception and saccadic eye-movements are more precise when directed at isoeccentric locations along the horizontal compared to vertical meridian. This effect is known as horizontal-vertical anisotropy (HVA). Given that eye-movement system plays an important role in spatial short-term memory (STM) it was hypothesized STM would also show a anisotropy. Consistent with this hypothesis online experiment revealed significant HVA (Experiment 1). persisted even were precluded by using very short display durations 2). However, there no colour span or orientation change detection task. It argued may result from greater imprecision representation of meridian relative maps underpinning STM, bilateral field advantage, some combination these mechanisms.

L-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...

Spatial Attention can Bias Search in Visual Short-Term Memory

Whereas top-down attentional control is known to bias perceptual functions at many levels of stimulus analysis, its possible influence over memory-related functions remains uncharted. Our experiment combined behavioral measures and event-related potentials (ERPs) to test the ability of spatial orienting to bias functions associated with visual short-term memory (VSTM), and to shed light on the ...

Life-span Changes in Visuo-spatial Short Term Memory

Several experiments are presented to evaluate the development of visuo-spatial short term memory from childhood to old age (from five-year-olds to about 70-year-olds). Visuospatial short term memory was assessed through transformational imagery tasks. The first set of experiments (chapters 3, 4 and 5) concerned the development of mental rotation abilities. A review of the literature suggested t...
