medication error (me) is the most common preventable cause of adverse drug events which negatively affects patient safety. inadequate, low-quality studies plus wide estimation variations in me from developing countries including iran, decreases the reliability of me evaluations. to clarify sources, underreporting reasons and preventive measures of mes, we reviewed iran current available literat...

Sensorimotor adaptation, the process that reduces movement errors by learning from sensory feedback, is often studied within a session of about half an hour. Within such a single session, adaptation generally reaches plateau before errors are completely removed. However, adaptation may complete on longer timescales: the slow components of error-based adaptation are associated with good retentio...

We investigated the relative contributions of perception and reference memory to behavioural variability in a temporal discrimination with human subjects. We used two temporal bisection tasks. In both tasks each trial consisted of a sequential presentation of three intervals, two standards, and a probe, and subjects were asked to judge the similarity of each probe against the two standards. In ...

From the perspective of an agent the input output behavior of the environment in which it is embedded can be described as a dynamical system Inputs correspond to the actions executable by the agent in making transitions between states of the environment Outputs correspond to the perceptual information available to the agent in particular states of the environment We view dynamical system identi...

Visual errors in the perception of written drug names can reflect orthographic similarity amongst certain names. Drug names are typically printed in lowercase text. 'Tall Man' lettering, the capitalisation of the portions that differ amongst orthographically similar drug names, is employed in the field of medication labelling and prescribing to reduce medication errors by highlighting the area ...

Misidentifications are a common phenomenon in unfamiliar face processing, but little is known about the underlying cognitive and neural mechanisms. We used the face identity-sensitive N250r component of the event-related brain potential as a measure of identity-sensitive face matching process in visual working memory. Two face images were presented in rapid succession, and participants had to j...

This study examines the relationship between speech perception and speech production in children with speech delay (SD). Sixtythree children who participated in the Nemours Genetics of Speech Delay Project were categorized as either typically developing (TD) or SD. The children with SD were subgrouped by their articulation errors on the /s/ and // sounds tested in a perception experiment. An i...

There are many instances in which human observers are the final judges of the quality of a compressed image. In such situations, it is useful to incorporate a model of the human visual system (HVS) into th e image compression system in order to reduce or even eliminate the visual distortions introduced to the reconstructed image. A compressed image is said to be perceptually lossless for a spec...

this study was an attempt to shed light on the relationship between perceptual learning styles and perceptual teaching styles of iranian efl learners and teachers. it further investigated the relationship between perceptual learning style and the age, gender, and proficiency of iranian efl learners. a total of 112 students and 23 teachers participated in this study. the data was collected using...

We propose a novel scheme to embed an invisible signature into an image to check image integrity and measure its distortion. The technique is based on the pseudo noise sequences and visual masking eeects. The values of an image are modiied by a pseudo noise signature which is shaped by the perceptual thresholds from masking eeects. The method is robust and can gauge errors accurately up to half...
