  • Effects of emotional response on the S troop‐like task in preschool children and young adults

    Open AccessYoshifumi Ikeda, Hideyuki Okuzumi et al.ARTICLEJapanese Psychological Research2014

    This study investigated the effects of emotional response on an inhibitory task, the S troop‐like day‐night task, in which participants are presented with two pictures. They are then requested to inhibit naming what the card shown to them represents and instead state what the other card represents. Specifically, 35 4‐ to 6‐year‐old children and 15 young adults were administered the emotion‐related happy‐sad task and the emotion‐unrelated up‐down …

  • Target-to-Distractor Ratio Effects on Decision Time in the Orderly Array Shape Cancellation Task

    Open AccessYoshimi Nakajima, Yoshifumi Ikeda et al.ARTICLEPsychological Reports2013

    The cancellation task is a paper-and-pencil test commonly used to assess attention or planning. This study investigated whether the decision time performance on the task was influenced by the number of targets and distractors. This study reduced the demand of planning and used an index of the decision time, an estimate of the time taken to decide whether to mark a stimulus. Forty healthy adults (M age = 21.3 yr., SD = 1.5) performed five cancella…

  • Age-Related Trends of Interference Control in School-Age Children and Young Adults in the Stroop Color–Word Test

    Open AccessYoshifumi Ikeda, Hideyuki Okuzumi et al.ARTICLEPsychological Reports2011

    In this cross-sectional study, differences in interference control, one component of executive function, were investigated among three age groups, 15 early childhood (7- to 8-yr.-olds), 25 middle childhood (9- to 12-yr.-olds), and 20 young adults (21- to 30-yr.-olds). Participants were administered a computer version of the Stroop color-word test with an oral response; correct responses, response time (RT), and the interference ratio were examine…

  • Developmental Changes of Speed-accuracy Trade-offs in Manual Skills

    Open AccessHideyuki Okuzumi, Mitsuru Kokubun et al.ARTICLEAnthropological Science2007References: 1

    本研究では,3つの手指運動課題を小学生と成人に行ない,学童期における道具操作の発達的変化を検討した。評価の観点は課題遂行速度と正確性であった。被験者は,小学生1年生~6年生60名(各学年10名)と成人大学生10名である。なぞり書き課題,折り紙課題,シール貼り課題という3つの課題を行い,それぞれ課題遂行時間(運動速度)と正確性を求めた。結果は以下の通りである。(1)幼児期においては運動の正確性は速度よりも発達的に先行した。(2)折り紙課題は全課題の中で最も早く発達的画期を示し,シール貼り課題はなぞり書き課題よりも発達的画期が先行した

  • Motor ability in adults with mental retardation evaluated by 7-item physical performance test

    Open AccessHideyuki Okuzumi, Michio Ushiyama et al.ARTICLEAnthropological Science2000

    According to the motor ability model (Nagasaki et al., 1995) constructed three factors (hand power, balance, and walking), a 7-item physical performance test (grip strength, tapping, one-leg standing with eyes open and with eyes closed, beam walking, preferred speed walking and maximum speed walking) was administered to 217 adults with mental retardation (age 18-68 years).(1) The relationships between chronological age and all of the physical per…

  • Sex Differences in Facial Skin Temperature When Exposed to Darkness With and Without Warning

    Atsushi Tanaka, Hideyuki Okuzumi et al.ARTICLEPsychological Reports1998

    The changes in skin temperature under anxiety were investigated by noninvasive measurements. The nasal skin temperature of 20 subjects was assessed by thermography. The measurement of the skin temperature by thermistor causes stress in subjects. The primary advantages of a thermography over use of a thermistor are noninvasive and accurate. Each subject was made anxious under the 2 conditions of sudden darkness (Sudden darkness condition) or exper…

    Open AccessIwao Kobayashi, Atsushi Tanaka et al.ARTICLEPsychological Reports1996

    In a school for the blind, computer use and feelings toward computers by 34 visually impaired students receiving secondary education and by their 42 teachers were investigated with a questionnaire.
