...Journal of Abnormal Psychology 1978, Vol. 87, No. 1, 49-74 Learned Helplessness in Humans: Critique and Reformulation Lyn Y. Abramson and Martin E. P. Seligman University of Pennsylvania John D. Teasdale Oxford University, England The learned helplessness hypothesis is criticized and reformulated. The old hypothesis, when applied to learned helplessness in humans, has two major problems: (a) It does not distinguish between cases in which outcomes are uncontrollable for all people and cases in which they are uncontrollable only for some people (univervsal vs. personal helplessness), and (b) it does not explain when helplessness is general and when specific, or when chronic and when acute. A reformulation based on a revision of attribution theory is proposed to resolve these inadequacies. According to the reformulation, once people perceive noncontingency, they attribute their helplessness to a cause. This cause can be stable or unstable, global or specific, and internal or external. The attribution chosen influences whether expectation of future helplessness will be chronic or acute, broad or narrow, and whether helplessness will lower self-esteem or not. The implications of this reformulation of human helplessness for the learned helplessness model of depression are outlined. Over the past 10 years a large number of experiments have shown that a variety of organisms exposed to uncontrollable events often exhibit subsequent disruption of behavior (see Maier & Seligman...

...138 IEEE TRANSACTIONS ON INDUSTRIAL INFORMATICS, VOL. 8, NO. 1, FEBRUARY 2012 A Fusion Approach for Efficient Human Skin Detection Wei Ren Tan, Chee Seng Chan, Member, IEEE, Pratheepan Yogarajah, and Joan Condell Abstract—A reliable human skin detection method that is adaptable to different human skin colors and illumination conditions is essential for better human skin segmentation. Even though different human skin-color detection solutions have been successfully applied, they are prone to false skin detection and are not able to cope with the variety of human skin colors across different ethnic. Moreover, existing methods require high computational cost. In this paper, we propose a novel human skin detection approach that combines a smoothed 2-D histogram and Gaussian model, for automatic human skin detection in color image(s). In our approach, an eye detector is used to refine the skin model for a specific person. The proposed approach reduces computational costs as no training is required, and it improves the accuracy of skin detection despite wide variation in ethnicity and illumination. To the best of our knowledge, this is the first method to employ fusion strategy for this purpose. Qualitative and quantitative results on three standard public datasets and a comparison with state-of-the-art methods have shown the effectiveness and robustness of the proposed approach. Index Terms—Color space, dynamic threshold, fusion strategy, skin detection. ...
