in the affective sphere of efl learning especially with regard to teaching/learning situations in iran, one deterrent element seizes particular attention and that is inhibition self-imposed restraint on or abstinence from learning due to academic and non-academic variables such as culture, gender, psyche, extreme emotions, etc. it is related to language ego permeability hypothesis (leph) which ...

Perceptual learning of motion direction discrimination is generally thought to rely on the middle temporal area of the brain (MT/V5). A recent study investigating learning of motion discrimination when MT was psychophysically suppressed found that learning was possible with suppressed MT, but only when the task was sufficiently easy [Lu, H., Qian, N., Liu, Z. (2004). Learning motion discriminat...

We studied perceptual learning in motion discrimination when the brain's middle temporal area (MT/V5) was functionally suppressed. This was achieved by using the "paired-dots" motion stimulus where the two dots in a pair always move in counter-phase over a short distance [J. Neurosci. 14 (1994) 7357]. The motion directional signal of the stimulus is therefore always 0 on average. As a result, t...

abstract alzheimer’s disease (ad) is the most common form of dementia has become one of the most severe progressive socio-economical and medical burdens facing countries all over the world. the drugs are currently available just able to delay the symptom progression of disease. this study try to evaluate protein profile of the effects of aqueous extract of lavender ( lavandula angustifolia ) on...

to explore the function of light-harvesting complex protein (lhcp) in arabidopsis growth and development, the leclere and bartel seed collection was screened. in this collection randomly cloned cdnas are expressed under the camv35s promoter. a pale green line has been identified and characterized in more details. analysis of the inserted cdna in the pale green line showed it encodes lhcb1 prote...

In the present study, the effects of morphine sensitization on morphine-induced impairment of memory formation and the state-dependent retrieval of a passive avoidance task learned under morphine influence have been investigated in mice. Pre-training administration of morphine (0.5, 2.5 and 5 mg/kg) dose dependently suppressed the learning of one-trial passive avoidance task. Pre-test administr...
