This study investigated the acute effects of passive whole body vibration (WBV) on executive functions in healthy young adults. Participants (112 females, 21 males; age: 20.5±2.2 years) underwent six passive WBV sessions (frequency 30 Hz, amplitude approximately 0.5 mm) and six non-vibration control sessions of two minutes each while sitting on a chair mounted on a vibrating platform. A passive...

PURPOSE The purpose of this study was to investigate the effect of Taekwondo exercise on Brain-derived neurotrophic factor and the Stroop test in undergraduate students. METHODS Fourteen male subjects participated in this study. They were separated into a Control group (N = 7) and an Exercise group (N = 7). Subjects participated in Taekwondo exercise training for 8 weeks. They underwent to Ta...

A growing number of human studies have reported the beneficial influences of acute as well as chronic exercise on cognitive functions. However, neuroimaging investigations into the neural substrates of the effects of acute exercise have yet to be performed. Using multichannel functional near-infrared spectroscopy (fNIRS), we sought cortical activation related to changes in the Stroop interferen...

OBJECTIVE To understand the relationships between brain structures and function (behavior and cognition) in healthy aging. METHOD The study group was composed of 56 healthy elderly subjects who underwent neuropsychological assessment and quantitative magnetic resonance imaging. Cluster analysis classified the cohort into two groups, one (cluster 1) in which the magnetic resonance imaging metr...

Prior research has demonstrated that explicit pre-cues informing participants of the proportion congruence of an upcoming list of Stroop trials affect performance in mostly congruent lists but not mostly incongruent lists. This pattern suggests a limited role for expectations in influencing Stroop performance. An alternative explanation, however, is that the effects of pre-cues may be masked by...

Models of attention and context effects in naming performance should be able to account for the time course of color-word Stroop interference revealed by manipulations of the stimulus onset asynchrony (SOA) between color and word. Prominent models of Stroop task performance (Cohen, Dunbar, & McClelland, 1990; Cohen & Huston, 1994; Phaf, Van der Heijden, & Hudson, 1990) fail to account for the f...

This study aims to examine the effects of 12 weeks physical-cognitive dual-task training on cognition, depression, sleep quality, and quality life in older women (n = 44; 66.20 ± 4.05 years). Of these, 22 were randomly allocated (DT) group, participated activities education control group (CG). Assessments performed at baseline, end intervention, after follow-up using following instruments: Trai...

The influence of word reading on Stroop color naming decreases as a function of the proportion of test items that are incongruent. This proportion-congruent effect is usually ascribed to strategies (e.g., maintaining task set) that operate at a general level to moderate the extent to which participants are influenced by word reading. However, in three experiments, effects at the level of specif...

Trail Making Test (TMT) has been widely used in Indonesia as an Executive Function (EF) test, however, no studies reported validity and reliability of the test. In this study, we analyzed TMT’s psychometric properties, including validity, effect demographic variables such education, age, sex on TMT, propose norm scores for urban population Java Island. Four hundred ninety persons (aged 16-80 ye...

BACKGROUND Investigators have used various experimental paradigms such as the Stroop colour naming test to study how adults with different emotional disorders process emotional information. However, to date, little research has been carried out on younger subjects. METHOD In the current experiment, children and adolescents with post-traumatic stress disorder (PTSD) and control subjects aged 9...
