Sensation seeking (SS) has traditionally been viewed as a phenomenon of the appetitive motivational system. The limited SS research exploring contributions from the aversive motivational system reveals greater anxious reactivity to dangerous activities among low sensation seekers. The present study extends this line of work by comparing levels of fear and anxiety during anticipation of predictable and unpredictable aversive stimuli across high- and low-SS groups. Low sensation seekers displayed greater fear-potentiated startle (FPS) to predictable aversive stimuli, and only those low on SS showed FPS and skin conductance response effects during experimental contexts in which aversive stimuli were delivered unpredictably. Findings implicate enhanced apprehensive anticipation among those low on SS as a potential deterrent for their participation in intense and threatening stimulus events. 相似文献

This article examines whether various cognitive abilities are associated with symptoms of ADHD. Cognitive ability is conceptualized using Cattell-Horn-Carroll (CHC) theory as measured using the Woodcock-Johnson Tests of Cognitive Ability (3rd ed.). This article also examines whether test session behavior mediates the association between cognitive ability and ADHD. Participants are children ages 6 to 12 with (n= 33) and without (n= 19) ADHD. Results show that inattentive symptoms of ADHD are significantly related to the CHC ability of processing speed above and beyond the effect of test session behavior. Symptoms of ADHD (both inattention and hyperactivity/impulsivity) are also significantly associated with visual spatial processing, but this is completely mediated by test session behavior. It is concluded that inattentive symptoms of ADHD are associated with slower processing speed and that this relationship is not explained by test session behavior. 相似文献

Anxiety disorders are currently one of the most common health concerns in the United States. Overall, they are the single largest cost to the healthcare system. They are also underdiagnosed and undertreated. Selective serotonin reuptake inhibitors and benzodiazepines appear to be the most common pharmacologic treatment approaches. Unfortunately, not all patients respond to these treatments. Many augmentation strategies have been tried in the past with varying levels of success or safety. This article describes a safe and highly effective augmentation technique in patients suffering from some of the most serious and debilitating forms of anxiety disorders, namely obsessive-compulsive disorder and panic disorder. 相似文献

The Emotional Foundation of Political Cognition: The Impact of Extrinsic Anxiety on the Formation of Political Tolerance Judgments 总被引:1,自引:0,他引:1
George E. Marcus John L. Sullivan Elizabeth Theiss-Morse Daniel Stevens 《Political psychology》2005,26(6):949-963
Common sense recognizes emotion's ability to influence judgments. We argue that affective processes, in addition to generating feeling states, also influence how political cognition is manifested. Drawing on the theory of affective intelligence, we examine the role that anxiety plays in how and when people rely on predispositions and when they rely on contemporaneous information in making political tolerance judgments. We report on two experimental studies to test our arguments. In the first study we find that extrinsic anxiety generates a resistance response among subjects who hold a strong predisposition and a receptive response among those who do not. In the second study we present subjects with explicit "frames" exposing them to a pro- or anti-free speech message. We find that extrinsic anxiety enhances responsiveness to frames while an absence of anxiety diminishes the impact of these frames. Taken together these results show that affective processes shape how people make political judgments. 相似文献

This article develops the cognitive—emotional forager (CEF) model, a novel application of a neural network to dynamical processes in foraging behavior. The CEF is based on a neural
network known as the gated dipole, introduced by Grossberg, which is capable of representing short-term affective reactions in a manner similar to Solomon
and Corbit’s (1974) opponent process theory. The model incorporates a trade-off between approach toward food and avoidance
of predation under varying levels of motivation induced by hunger. The results of simulations in a simple patch selection
paradigm, using a lifetime fitness criterion for comparison, indicate that the CEF model is capable of nearly optimal foraging
and outperforms a run-of-luck rule-of-thumb model. Models such as the one presented here can illuminate the underlying cognitive
and motivational components of animal decision making. 相似文献

This paper presents conceptual arguments to suggest that trust within organizations and trustworthiness of organizations are
built through ethical governance mechanisms. We ground our analysis of trust, trustworthiness, and stewardship in the business
literature and provide the context of business school governance as the focus of our paper. We present a framework that highlights
the importance of knowledge, resources, performance focus, transparency, authentic caring, social capital and citizenship
expectations in creating a basis for the ethical governance of organizations.
A version of this paper was presented at the European Academy of Management, 2005. 相似文献

Widows, women, and the bioethics of care must be understood within an authentic Christian ontology of gender. Men are men and women are women, and their being is ontologically marked in difference. There is an ontology of gender with important implications for the role of women in the family and the Church. The Christian Church has traditionally recognized a role for widows, deaconesses, and female monastics, which is not that of the liturgical priesthood, but one with a special relationship to care and therefore with particular implications for health care and a Christian bioethics of care in the twenty-first century. In the shadow of early male mortality, women as wives should turn to support their husbands and as widows to support those in need. Widows, in becoming authentic Christian monastics, can bring into the world an icon of rightly ordered women providing rightly ordered Christian care for those in need. They can enter the moral vacuum created by misunderstandings of the place of women and the service vacuum created by a disappearance of religious nuns in Western health care facilities with a presence that is at one with the Church of the Fathers. 相似文献
