习得性无助面面观

<正>习得性无助是指个人经历了挫折与失败后,在面临问题时产生的无能为力之感。1975年,美国心理学家、积极心理学之父马丁·塞利格曼(Martin E.P.Seligma)用狗做实验,生动地演示了"无助感"形成的过程。自塞利格曼提出后,习得性无助现象受到了心理学家的广泛关注。塞利格曼:绝望的狗塞利格曼在实验中把狗分为实验组和控制组。首先把实验组放进一个设有电击装置但又无法逃脱的笼子里。然后给狗施加电击,电击的强度足以引起狗的痛苦体验。实验者发     

习得无助理论模型的演变与争议

习得无助理论是由美国心理学家马丁．塞里格曼于上世纪60年代提出、而后在美国以至全世界引起广泛研究热潮的一种心理学理论,围绕着习得无助产生的机制及实验操作中的关键变量,形成了许多有价值的理论模型。该研究介绍了这些理论模型的起源、发展与演变．以及无助现象对人们的认知、情绪和动机造成的损害,为我们在临床上诊断和治疗抑郁提供了一个新的视角,同时为预测和矫治学生的习得无肋感提供了方法上的借鉴。     

习得无助感理论发展研究的简评

习得无助感 (ｌｅａｒｎｅｄｈｅｌｐｌｅｓｓｎｅｓｓ)是近年来西方动机研究中的一个焦点 ,它指有机体经历了某种学习后 ,在情感、认知和行为上表现出的消极的特殊的心理状态。自六十年代Ｓｅｌｉｇｍａｎ提出后就引起了许多心理学家的关注 ,并在多个领域开展了研究。1　以控制性为基础的早期理论在Ｓｅｌｉｇｍａｎ提出“习得无助感”之前 ,已有心理学家发现了这种特殊的心理现象 ,并把这种现象当作一种烦恼或动物病理看待。它的提出源于Ｓｅｌｉｇｍａｎ＆Ｍａｉｅｒ(1967)对狗的实验 ,后来在其他动物和人类身上也发现了这种现象 ,发现了…

从习得无助、习得乐观到积极心理学—— Seligman对心理学发展的贡献

Seligman先生开创了习得无助和习得乐观的研究领域。20世纪末他树立起积极心理学的大旗,将心理学引向探索和促进人类性格力量发展和美德完善的轨道,反转了20世纪中后期心理学过分关注人性的消极面和弱点的研究取向,界定了积极心理学三个明确的研究领域：积极的情感、积极的特征和积极的社会制度。他提出幸福的三要素原则,并运用幸福理论治愈抑郁和提升人们的幸福感。近年来他致力于研究人类的美德和优势,并提出运用美德和优势治疗心理疾病的积极心理治疗理论（PPT）     

信息反馈不一致导致习得无助机制的实验研究

研究以90名大学生为被试,探讨认知活动中,信息反馈不一致性和操作成绩评价反馈导致大学生无助现象的机制。结果表明:认知活动中,信息反馈不一致,损害了被试的认知和情绪,对动机的损害没有达到显著性水平;实验中是否给予被试操作成绩评价,对被试的动机、认知和情绪影响不显著。说明在认知活动中,信息反馈不一致,是导致习得无助的关键因素,是否对被试的操作成绩给予评价反馈,不会导致习得无助,验证了习得无助的信息加工理论模型。实验也表明,信息反馈不一致不会形成被试反应性的抑郁。     

习得性无力感理论浅析

习得性无力感,简称为无力感,是learned helplessness 一语的意译,指的是一种通过某种学习经验而形成的会给以后学习带来消极影响的特殊心理状态。从六十年代后期开始,国外对此问题进行了大量研究,最初以动物为实验对象,后来扩展到以人为研究对象,并形成了系统的理论。现在这一理论经常被用于说明人类的丧失信心、自甘暴弃等行为的形成和抑郁症的产生。本文拟就对这方面的研究和理论作一简括的介绍和分析。     

评述基于认知加工的第二语言习得研究

认知加工研究范式是第二语言习得内在因素研究的一个重要方法,它代表第二语言习得向计量研究发展的方向。这一范式注重研究习得动态过程,不仅关注学习者习得什么和为什么能习得,更关注学习者是怎样掌握目标语规则的过程。除了计量研究特点外,该范式还从语言本体研究范式合理吸收了有关理论和方法,这些对汉语作为第二语言习得研究都具有借鉴意义。

Learned helplessness in the rat.

Four experiments attempted to produce behavior in the rat parallel to the behavior characteristic of learned helplessness in the dog. When rats received escapable, inescapable, or no shock and were later tested in jump-up escape, both inescapable and no-shock controls failed to escape. When bar pressing, rather than jumping up, was used as the tested escape response, fixed ratio (FR) 3 was interfered with by inescapable shock, but not lesser ratios. With FR-3, the no-shock control escaped well. Interference with escape was shown to be a function of the inescapability of shock and not shock per se: Rats that were "put through" and learned a prior jump-up escape did not become passive, but their yoked, inescapable partners did. Rats, as well as dogs, fail to escape shock as a function of prior inescapability, exhibiting learned helplessness.     

Learned helplessness and learned effectiveness: effects of explicit response cues on individuals differing in personal control expectancies

Female undergraduates (n = 62) who scored as extreme internals or externals on the Mirels Personal Fate Control Scale participated in a partial replication of Hiroto's learned helplessness experiment. Lights were added to the treatment apparatus, which made explicit to subjects the contingency or noncontingency between their responses and the termination of an aversive tone. As predicted, the performance of internals was significantly impaired by uncontrollability (learned helplessness), while that of externals was facilitated by controllability (learned effectiveness). Externals performed as well as internals in the "escapable" condition, but their performance was inferior to that of internals in the control condition. Following "inescapable" treatment, internals performed worse than externals. These results are supportive of Lefcourt's theory of cue explication. Implications for locus of control and learned helplessness research are discussed.     

Immunization against learned helplessness in the cockroach (Periplaneta americana)

Cockroaches exposed to one day of escapable shock prior to three days of inescapable shock did not become helpless on a shuttlebox-escape task. Like dogs and rats, cockroaches are immunized against learned helplessness by prior experience with escapable shock.     

Therapy and immunization of long-term analgesia in rats

Three experiments are reported which examine the effects of experience with escapable shock either subsequent to (Experiment 1) or prior to (Experiments 2 and 3) a session of inescapable shock on the subsequently produced long-term analgesic reaction in rats. Experment 1 demonstrated that experience with escapable shock 4 hr after a session of inescapable tail shock completely reverses the analgesic response that is normally observed 24 hr later upon reexposure to shock. The escapability of the shock was shown to be the important factor in reversing the analgesic reaction, since subjects given inescapable shock in amounts equivalent to escape subjects exhibited no reduction in analgesia. Experiment 2 showed that experience with escapable shock 4 hr prior to a session of inescapable tail shock could also completely eliminate the long-term analgesic reaction. Experiment 3 replicated the results of Experiment 2, but employed a different escape task and temporal parameters in order to extend the generality of the findings, and to more closely match the procedures employed in behavioral experiments reported by J. L. Williams and S. F. Maier (Journal of Experimental Psychology: Animal Behavior Processes, 1977, 3, 240–253). The implications of these results for the areas of pain control and learned helplessness were discussed.     

Frustation and learned helplessness.

This article reports the transfer of learned helplessness from one aversive motivator, shock to another, frustration. In experiment 1, animals were trained to approach food in a runway and concomitantly exposed to either escapable, inescapable, or no shock in a different situation. Extinction was conducted in the runway, and subsequently the animals were tested for hurdle-jump escape from the frustrating goal box. Inescapably shocked rats failed to learn to hurdle-jump, whereas escapably or nonshocked animals learned the frustration escape response. Experiment 2 replicated the basic finidngs of Experiment 1 and showed transfer of learned helplessness from shock to frustration when no running response had been first acquired in the runway.     

Learned helplessness in high school students following experience of noncontingent rewards

High school students differing in achievement motivation were subjects in a learned helplessness experiment using a yoked triadic design with noncontingent rewards. A strong helplessness effect was observed in both high- and low-achievement motivation groups. A postexperimental questionnaire revealed that perceived response-outcome independence was induced under the noncontingent reinforcement condition, but was not associated with perceived failure. The results were seen as strong support for the original learned helplessness model in two important respects. First they refute recent claims that learned helplessness depends on aversive outcomes, and second they show that human helplessness can be distinguished from experimenter-induced failure.     

Learned helplessness,depression and the perception of reinforcement

Depressed and nondepressed subjects were given escapable, inescapable, or no noise. Then, their perceptions of reinforcement contingencies in skill and chance tasks were assessed. Depressed-no noise and nondepressed-inescapable noise subjects exhibited smaller decreases in expectancy following failure in skill, but not in chance, than nondepressed-no noise subjects. So, depression and inescapable noise both produced perception of failure in skill as response-independent. Contrary to predictions, neither depression nor inescapable noise had a significant effect on increases in expectancy after success. These results partially support the learned helplessness model of depression which claims that a belief in independence between responding and reinforcement is central to the etiology and symptoms of depression in man.     

Learned helplessness as a schedule-shift effect

The essentials of learned helplessness theory are described and supporting evidence surveyed. It is shown that two main empirical phenomena are associated with learned helplessness: a low rate of responding in laboratory animals following numerous discrete trials with continuous free relief and in human subjects following continuous nonrelief/reward or traditional extinction. The explanation Seligman and Maier give for these findings is critically analyzed and found to be unsupported at several critical points. The “patchwork” nature of the theory and observations is considered and it is contended that what is new in learned helplessness research is a schedule-shift effect like that observed when extinction follows partial reinforcement. A schedule-shift discrimination theory of “learned helplessness” effects is offered which is closely parallel to a widely accepted explanation of other schedule-shift effects, notably the partial reinforcement extinction effect. Although the behavioral effects of some schedule shifts resemble clinical depression, the latter is a more complex behavioral phenomena than the former which in turn has broader relevance to human behavior than just depression.
