This study aimed to examine the characteristics of handedness in Japanese adults based on gender differences, the presence of left-handed (LH) relatives and experiences with the forced conversion of handedness. Subjects were comprised of 4668 Japanese adults ranging from 15 to 29 years of age (3127 males 18.8±1.8 years old and 1541 females 18.8±1.4 years old). We investigated their subjective handedness, the presence and type of LH relatives, and their experiences with forced conversion of handedness. Although there was no gender difference in the incidence of “innate LH (a subject who had experienced forced conversion of handedness, or a LH subject without experience in the forced conversion)”, females underwent more forced conversion of handedness and had a higher incidence of subjects whose handedness changed from LH to RH. There was no significant difference in the proportion of forced conversion based on the presence of LH relatives, but the incidence of innate LH was higher in subjects with LH relatives and the proportion of LH subjects who remained unchanged after forced conversion was also higher in subjects with LH relatives. Among the subjects with LH relatives, the incidence of current LH was significantly higher in subjects with LH grandparents or parents than siblings. These findings may suggest that forced conversion may influence a gender difference in the incidence of LH. In addition, the presence of LH relatives genetically and environmentally (imitation) influences handedness, and the influence is greater in parents than siblings.

新入生に対し、大学に対する不本意感および学業へのつまずき感に関する調査を2回(入学当初および1年終了時)実施し、追跡が可能であった1,411 名を対象に、その特徴を検討した。1年次春の時点で大学への不本意感は約1割、学業へのつまずき感は約2割の学生が有していた。これらの割合は冬の調査時点でも同等であったが、構成している学生の約半数は入れ替わっていた。大学への不本意感が春から冬にかけて生じた学生は、受験の失敗に対する思いが再燃し、自身の理想とする大学像とのギャップや授業内容・カリキュラムに対する不満が高まっていた。同様に、学業へのつまずき感が春から冬にかけて生じた学生は、課題遂行の困難さや学業への不向きさを自覚しながら、単位取得・留年・卒業への不安が高まる傾向にあった。;This study researched the characteristics of the university freshmen who are unwilling to join the university and who feel anxiety about academic learning for 1,411 university freshmen. A biannual survey on the unwillingness to join the university community and anxiety about academic learning was conducted in spring (the end of May) and winter (December to February). About 10 % of the freshmen were unwilling to join the university, and about 20% of them had anxiety about academic learning in the spring. Although these percentages did not change in the winter, half of the persons with the unwillingness or anxiety was replaced by another persons. The students, who were unwilling to join the university during the spring and winter months, reignite a sense offailing to enter university, and more dissatisfied with academic curriculum or lesson contents. Similarly, the students, who feel anxiety about academic learning during the spring and winter months, realized difficulty to class assignments and unfit for academic learning, and increased anxiety about acquisition of academic credit, graduation, and staying back a year.
