Retinal and cortical patterns of spatial anisotropy in contrast sensitivity tasks
It has often been postulated that asymmetries in performance within the visual field (VF) are not characteristic of early visual processing. Here, human retinal (naso/temporal), cortical (left/right) and superior/inferior patterns of asymmetry were explored with achromatic contrast sensitivity (CS) tasks, that probed distinct spatiotemporal frequency channels. Low spatial, high temporal frequen...
متن کاملassessment of deep word knowledge in elementary and advanced iranian efl learners: a comparison of selective and productive wat tasks
testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
patterns and variations in native and non-native interlanguage pragmatic rating: effects of rater training, intercultural proficiency, and self-assessment
although there are studies on pragmatic assessment, to date, literature has been almost silent about native and non-native english raters’ criteria for the assessment of efl learners’ pragmatic performance. focusing on this topic, this study pursued four purposes. the first one was to find criteria for rating the speech acts of apology and refusal in l2 by native and non-native english teachers...

Running Head: SPATIAL CONTRAST SENSITIVITY IN AUTISM Spatial Contrast Sensitivity in Adolescents with Autism Spectrum Disorders
Adolescents with Autism Spectrum Disorders (ASD) and typically developing (TD) controls underwent a rigorous psychophysical assessment that measured contrast sensitivity to seven spatial frequencies (0.5 to 20 cycles/degree). A contrast sensitivity function (CSF) was then fitted for each participant, from which four measures were obtained: visual acuity, peak spatial frequency, peak contrast se...
