The present study was an attempt to provide a psycholinguistic account of cognitive processes underlying responding and questioning. It also strived to identify the potential differences between responding and questioning cognitive processes in Target Language Use Situation tasks. To accomplish the objectives, 65 Iranian general IELTS applicants from two foreign language learning instit...

objectives: this study aimed to compare elderly fallers and non fallers by balance test under dual tasks conditions. methods & materials: this study was a analyse-comparative study. subjects were chosen from three parks of tehran. subjects were 20 older adults with no history of falls (aged 72.60±5years) and 21 older adults with a history of 2 or more falls in the last one year (aged 74.50±6 ye...

Head motion is a fiequent problem in functional magnetic resonance imaging (fMRI) studies due to long expriment times, srnail signal changes associated with brain activation, and head motion produced by behavioural tasks. Current rnethods to minimize and correct for head movement do not completely solve the problem, particularly for specific patient populations. Head motion characteristics of s...

Simultaneous execution of cognitive and sensorimotor tasks is critical in daily life. Here, we examined whether dexterous manipulation, a highly habitual and seemingly automatic behavior, involves high order cognitive functions. Specifically, we explored the impact of reducing available cognitive resources on the performance of a precision grip-lift task in healthy participants of three age gro...

The expectancy versus pharmacological effects of alcohol have been primarily studied in relation to social and affective behaviors. The present study extended this type of investigation to perceptual, cognitive, and motor behaviors and utilized two alcohol dosages. Forty-two male undergraduate social drinkers, ages 18 to 25 years, were led to expect either alcohol or tonic. After actually consu...

Cognitive decline is apparent in the early stages of Huntington's disease and progressively worsens throughout the course of the disease. Expression of the human Huntington's disease mutation in mice (R6/2 line) causes a progressive neurological phenotype with motor symptoms resembling those seen in Huntington's disease. Here we describe the cognitive performance of R6/2 mice using four differe...

Cognitive and motor processes are essential for optimal athletic performance. Individuals trained in different skills and sports may have specialized cognitive abilities and motor strategies related to the characteristics of the activity and the effects of training and expertise. Most studies have investigated differences in motor-related cortical potential (MRCP) during self-paced tasks in ath...

Using motor imagery, we investigated brain activation in simple and complex walking tasks (walking forward and backward on a treadmill) and analyzed if the motor status of older adults influenced these activation patterns. Fifty-one older adults (64-79 years of age) were trained in motor execution and imagery and then performed the imagination task and two control tasks (standing, counting back...

The present study investigated the interactions between motor action and cognitive processing with particular reference to kanji-culture individuals. Kanji-culture individuals often move their finger as if they are writing when they are solving cognitive tasks, for example, when they try to recall the spelling of English words. This behavior is called kusho, meaning air-writing in Japanese. How...
