問題 关于大小与距离知觉的相互关系問題,近年来有不少研究。继郝尔威和波林(A.H.Holway and E.G.Boring)关于大小知觉恆常性的著名研究之后,勃朗斯威克(E.Brunswik)、吉伯逊(J.J.Gibson)、吉林斯基(A.S.Gilinsky)等人,对此問題进行了大量研究。他们在很大范围应用并发展了a=A/D(网膜視象大小=知觉大小/知觉距离)这一公式,尝試以数学函数說明知觉大小与知觉距离之間的关系。海諾曼和納赫麦斯(E.G.Heinemannand J.Nachmias)根据控制眼球运动調节的研究,提出大小知觉恆常性并不依賴于距 相似文献

在航空事业发展的初期,最早建立空軍的一些国家,对飞行員的选拔沒有什么严格規定,只要对飞行有兴趣的人均可报名入伍。但是很快就暴露出一些严重的問題。据統計,在第一次世界大战期間,协約国的飞行員由飞机中弹而造成事故的仅占2%,由于机械故障而造成事故的占8%,而90%的事故是由于飞行員操纵錯誤所造成的。这样,关于飞行 相似文献

Psychological distress is particularly common with any cancer diagnosis. This paper examined the psychological distress in a cohort of women newly diagnosed with breast cancer and postulates on the underlying theory. A longitudinal study of a cohort of women (n = 147) diagnosed with breast cancer (within the past 1 year), was conducted at University Malaya Medical Centre, Kuala Lumpur. Data were collected at baseline and at post 4‐week intervention. Analysis of variance was conducted to examine for any significant differences in the change‐scores between the experimental group (n = 69) and the control group (n = 78). Using the change scores, analyses of variance showed significant differences between groups for stress, F(1, 140) = 13.68, p < .0001, anxiety F(1, 140) = 8.44, p < .004, and depression, F(1, 140) = 11.57, p < .0001. Levels of stress, anxiety and depression generally decreased significantly in the experimental groups, p < .05, but either maintained or increased in the control group. This study indicates that the level of psychological distress of women with breast cancer can be ameliorated with a 4‐week self‐management intervention. Lower stress levels were also found in women who reported engagement in higher physical activity than women with low physical activity. 相似文献
