9、我们有一个虚无假设。另一位科学哲学家 （英）伊姆雷拉卡托斯，提出理论首先要证实它们自己的正确性，这样才能够发展进步。 Lakatos 建议，无论是理论还是范式都应该有一帮中坚分子坚定地保护重要假设和一条辅助假设，而这一保护带在某种程度上要支持被证实其虚假性，然而，这一保护带应该保持理论的真实性和可信性。 Lakatos 补充说，一个好的理论还应该有正面的启发式论据未来的研究计划，以产生新的假设，产生意想不到的结果。理论可以提供一定的法则和原理来预测未来，当然，它是建立在以下条件基础上的predict the future,butthis can onlyoccur ifa. a determi

11、 we can never prove that our next observation will not refute our law . Induction is the basis for inferential statistics which talk about the probability of chance factors causing the results.3 Control theories should be useful and have practical implications, such as solving problems and improving

12、 the human condition. However , complete control may be impossible in practice , due to the complexity of situations and the probabilistic nature of scientific laws . Knowing the high probability that something will occur 99 will not guarantee that it will occur on a certain occasion .Ethical issues

15、PSYCHOLOGICAL THEORIES AND HYPOTHSISThe different approaches to psychology fulfill these principles to varying degrees ：（ 1 ） Psychoanalysis has great explanatory power and understanding of behaviour ,but has been accused of only explaining behaviour after the event ,not predicting what will happen

16、in advance and of being unfalsifiable/unrefutable .Some have argued that psychoanalysis has approached the status more of a religion than a science, but it is not alonein being accused of being unfalsifiable（ evolutionary theory has too why isanything the way it is？because it has evolved that way ！）

17、 and like that all theories that are difficult to refute the possibility exists that it is actuallyright .Kline(1984) argues that psychoanalytic theory can be broken down into testable hypotheses and tested科学的方法论科学应该以公正客观的方式测试它的假设，这就意味着其条款应该具有可操作性及其方法应标 准 化 、具有可控 性和可 验 证性 。心 理理 论与 假设心理学不同的方法在不同程度上践行

18、着这些原则（ 1）精神分析学 对人的行为有很好的解释和理解，但它只能用来描述事件发生后的行为表现，而无法提前预测未来发展，也不具有可证伪性和反驳性。有的人认为精神分析学在地位上更接近一种宗教而非科学，当然像这样被认为不可证伪的理论不止它一个，像所有很难被驳倒的理论一样，也有可能存在着 , 事实证明确实如此。（进化论也是这样事情为什么是这样的呢？因为它就是这样进化的） ，像那些所有难以批驳的理论一样可能它们本来就是完全正确的。卡尔认为 , 精神分析理论可以被分解为能够检验的假设并得到科学的检验。例如， Scodel 假定口唇依赖的人更偏好大的乳房（正相关），但事实上发现是显著的负相关，尽管弗洛伊

19、德理论也可以用来解释了这一结果，但是卡尔却指出，既然没有显著性的关联，就应该拒绝理论。（ 2）人本主义刻意与科学的观点保scientifically. For example ,Scodel(1957) postulated that orally dependent man would prefer larger breasts（a positive correlation ） ,but in fact found significantly the opposite（ a negative correlation）.Although Freudian theory could also b

25、determination from the environment （it was only when this assumption faced overwhelming criticism by the cognitiveand ethological theories that behaviourist paradigm was overthrown）. Behaviorists firmly believed in the scientific principles of determinism and orderliness, and thus came up with fairl

26、y consistent predictions about when an animal was likely to respond （although they admitted that perfect prediction for any individual was impossible） . The behaviorists used their predictions to control the behavior of both animals（ pigeons trained to detect life jackets）and humans（behavioral therapies）and indeed Skinner , in his book Walden(3)行为主义有简洁的学习理论，用一些简单的规则（如强化、行为塑造、概括化等）来解释大量行为，从语言学习到道德发展。它提出了大胆精确的抗辩假说使其拥有一个核心的假设，比如环境决定论 (只有当这一理论假设面对认知和习性学理论者如此猛烈的批评时，行为主义者范式才被推翻 )。行为主义者坚定相信决定论和整齐性的科学准则 ,并且也因此提出什么时候动物可能进行反应的相当稳定地预测的方法（虽然他们承认 ,完美的预测 ,对任何个人是不可能的）。行为学家使用他们的预测来控制动物 ( 如鸽子训练来侦测救生衣 )和
