purpose: to determine the correlation between hand dominancy and eye dominancy with visual acuity and refraction in subjects with refractive errors. methods: this cross-sectional study includes 620 patients undergoing lasik. their refractive error (dry and cycloplegic), hand dominancy, eye dominancy (by hole-in-the-hand method) and visual acuity were determined. exclusion criteria were monocula...

The present study examined the acquisition of anaphora in English by Iranian EFL learners as well as Persian speaking children. To do so, the study was conducted in three phases. In the first phase, 40 intermediate female and male EFL learners were selected from Puyan Institute in Takestan, Iran. Then, an off-line based Grammatical Judgment Task was administered. In the second phase, 40 female ...

purpose: the traditional view regards limb selection in reaching a hemispheric specialization and an permanent biological phenomenon. however, recent studies have questioned this idea. instead, they suggest that the task conditions is also an effective factor. the present study includes two experiments in right and left handed children examining the effect of object location as a task condition...

The P3(00) event-related potential (ERP) was elicited in 80 normal, right-handed male subjects using a simple auditory stimulus discrimination task, with electroencephalographic (EEG) activity recorded at 19 electrodes. P300 amplitude was larger over the right compared to left hemisphere electrode sites primarily at anterior-medial locations (F3/4, C3/4) for both target and standard stimuli. Th...

Low perceptual familiarity with relatively rarer left-handed as opposed to more common right-handed individuals may result in athletes' poorer ability to anticipate the former's action intentions. Part of such left-right asymmetry in visual anticipation could be due to an inefficient gaze strategy during confrontation with left-handed individuals. To exemplify, observers may not mirror their ga...

BACKGROUND/AIM Central venous catheters (CVC) are at the crucial importance, particulary in the intensive therapy units. In order to handle a CVC safely, nursing students need to acquire theoretical and practical knowledge during the course of their studies. The aim of the study was to establish theoretical knowledge of nursing students about the procedures of nurses in placing and removing a c...
