在现代社会,有人认为缺乏儿童发展知识或没有受过有关方面训练的人也能够成为一个好父亲(母亲).然而,父母们很快就会知道要做合格的父母是生活中最艰难复杂的任务之一.在过去,也就是在社会人员流动较小的时代,通常由大家族的成员们——如祖父母,父辈亲属或堂兄弟——为刚作父母的年轻人传授作父母的实际知识(Bronfenbrenner,1970)但是在现代工业技术高度发展的社会,迫切需要进行父母教育的新方法(Henry,1981). 相似文献

在历史上,伦理学以什么途径和渠道对人们的道德产生过影响?在当今条件下,它还可能继续产生影响吗? 提出这个问题的本身就为在伦理学与其研究对象的相互作用上区分“现存的东西”和“应有的东西”的必要性奠定了基础。由于这种区分具有具体历史的制约性,所以它不仅取决于伦理或道德方面的可能和需要,而且更加取决于理论的完备,即不是简单地追随着精神生活,而是要“超前反映”人类的精神生活,从而使伦理道德理论成了“宁静日常生活的干涉者”,积极参与着对道德生活进程的指导。 相似文献

对那些不清楚拉丁美洲思想特殊发展的人来说,拉丁美洲哲学是否存在是他们要提出的第一个问题:“存在拉美哲学这种东西吗?”或者“所指的拉美哲学是什么意思?”产生这些问题,是因为哲学一般地讲并不限定是属于哪种民族和文化的。即使用这样限定的话,一般也不是我们在这里所说的,即“拉丁美洲”,这种限定。哲学一般认为是仅 相似文献

1.问题在最近几个世纪中,一种自豪和乐观的精神使西方文化闻名于世:对作为人理解和驾驭自然界的手段的理性的自豪;对实现人类最渴求的希望即为最大多数人取得最大幸福的乐观。人的自豪是有道理的。他凭借着理性创造出一个物质世界,其现实甚至胜过了各种神话故事和乌托邦的梦想与幻想。他利用了各种物质能力,它们将使人类能保证获得有尊严和生产性的存在所必不可少的物质条件,尽管他的许多目的还未达到,但几乎毫无问题,这些目的是能够达到的。生产的问题(这是个老问题)原则上解决了。现在,人在他的历史上第一次能够感觉到,人类统一和为人而征服自然的思想不再是一种梦幻,而是一种现实的可能性。难道他没有理由感到自豪,自信并对人类的将来充满信心吗? 相似文献

“人”的概念是西方哲学中的最中心概念之一,但是毫无疑问,它并不是一个人们具有统一意见并且得到明确定义的对象。这个概念的出现乃是由于人(不论是个人还是人类这一物种)的一种需要:把他们自己理解为一种特殊的和与众不同的东西。并且,这种不同的性质既是形而上学的又是伦理学的。关于人格(personhood)的形而上学的问题乃是何种特质和属性从本质上把人同所有其他类型的实体区分开来的问题;伦理学的问题乃是人的何种东西使得他们既具有道德价值(因此不应该以某些方式对待他们)又具有道德责任(因此对他们的行动能合理地进行褒、贬、奖、罚)的问题。人的形而上学的概念同伦理学概念之间的关系并不总是清楚的:它们是否是相同的概念、相同的实体概念、抑或一个是另一个的充分必要 相似文献

Fixed-ratio pausing: Joint effects of past reinforcer magnitude and stimuli correlated with upcoming magnitude 总被引:8,自引:8,他引:0 下载免费PDF全文
Pigeons responded on fixed-ratio schedules ending in small or large reinforcers (grain presentations of different duration) interspersed within each session. In mixed-schedule conditions, the response key was lit with a single color throughout the session, and pausing was directly related to the past reinforcer (longer pauses after large reinforcers than after small ones). In multiple-schedule conditions, different colors accompanied the ratios ending in small and large reinforcers, and pausing was affected by the upcoming reinforcer as well as the past one. Pauses were shorter before large reinforcers than before small ones, but they continued to be longer after large reinforcers than after small ones. The influence of the past reinforcer was modulated by the magnitude of the upcoming reinforcer; in the presence of the stimulus before the small reinforcer, the effect of the past reinforcer was enhanced relative to its effect in the stimulus before the large reinforcer. These results show that pausing between ratios is jointly determined by two competing factors: past conditions of reinforcement and stimuli correlated with upcoming conditions. 相似文献

Three rats earned their daily food ration by responding during individual trials either on a lever that delivered one food pellet immediately or on a second lever that delivered three pellets after a delay that was continuously adjusted to ensure substantial responding to both alternatives. Choice of the delayed reinforcer increased when the number of trials per session was reduced. This result suggests that models seeking closure on choice effects must include a parameter reflecting how preference changes with sessionwide income. Moreover, models positing that reinforcer probability and immediacy (1/delay) function equivalently in choice are called into question by the finding that probability and immediacy produce opposing effects when income level is changed. 相似文献

The construct accessibility model (CAM) holds that constructs are most likely to influence behavior when they are accessible in memory. While the theory of reasoned action sees intention as an important determinant of behavior, the CAM predicts that the intention to act upon a given health behavior is not likely to be acted upon unless the intention is in an accessible state. Therefore, people who frequently talk about or think about using condoms are likely to have condom related constructs available and use them when needed. This paper reports findings from the pilot phase of a project to identify beliefs which influence condom use in Hispanic and African-American youth living in Detroit. 15 male and 15 female Hispanics and 17 male and 17 female African-Americans aged 15-21 years of mean and median age 18.5, were interviewed face-to-face in 1989 with the goal of identifying condom beliefs which may influence their condom use. 80-82% of male participants, 53% of Hispanic females, and 100% of Black females had experienced sexual intercourse, with age at first intercourse ranging between 13.1 and 16.5 years. 88% of Black women and 7% of Hispanic women were pregnant at the interview. Regarding participants' level of preventive knowledge, all but 1 recently immigrated Hispanic female knew HIV was transmitted by needles and sexual intercourse. 87% of Hispanics and 94% of African-Americans responded that condoms protect against AIDS, but only 13% of Hispanics and 47% of African-Americans knew that nonlatex condoms do not. Some participants expressed concern that condoms reduce sensitivity and/or break during intercourse. Controlling for sexual activity, 25% of Hispanic females, 83% of Hispanic males, 71% of African-American females, and 80% of African-American males had ever used a condom; no Hispanic and 14% of Blacks reported using them consistently in the 12 month period preceding the interview. With 100% of African-American males and 97% of Black females reporting thinking about using condoms compared to 80% of Hispanics, the study findings suggest that condom intentions are more accessible in African-Americans than among Hispanics. 相似文献
