Theories of Emotion

According to appraisal theory, our interpretation of a situation causes an emotional response that is based on that interpretation.

Introduction Obsessive-Compulsive Disorder OCD is characterized by the world health organization as a major cause of mental disturbance. Biological approach is one of the viewpoints in the field of etiology of psychological disorders, especially the OCD. Losing the interaction between the two systems can also result in a similar outcome. Hence, intermediary mechanisms such as disgust sensitivity have been proposed for a better understanding of the relationship between brain-behavioral systems and OCD. Disgust as a negative and inclusive emotion involves a feeling of intense hatred and reluctance, which encompasses different physiological, cognitive, and behavioral dimensions.

Simone G. Recent evidence suggests that there are two possible systems for empathy: a basic emotional contagion system and a more advanced cognitive perspective-taking system. However, it is not clear whether these two systems are part of a single interacting empathy system or whether they are independent. Additionally, the neuroanatomical bases of these systems are largely unknown. In this study, we tested the hypothesis that emotional empathic abilities involving the mirror neuron system are distinct from those related to cognitive empathy and that the two depend on separate anatomical substrates.

Thousands of answers have been offered—but surprisingly few by biologists, including brain scientists. While scientists regard other complex emotional states such as depression, anxiety, or fear as complex, but not unfathomable, love is relegated to the poets and songsters. Certainly such love can be a joyous state, but it is also capable of producing deeply disturbing, even dangerous results. At least 25 percent of homicides in the United States involve spouses, sexual partners, or sexual rivals. Each year, some one million American women are followed and harassed by rejected lovers; , men are stalked by former partners; and approximately 1. In fact, male sexual jealousy is the foremost cause of wife battering in cultures worldwide. Husbands, although to a lesser degree, are physically abused by wives.

Recent years have witnessed the emergence of powerful new tools for assaying the brain and a remarkable acceleration of research focused on the interplay of emotion and cognition. This work has begun to yield new insights into fundamental questions about the nature of the mind and important clues about the origins of mental illness. In particular, this research demonstrates that stress, anxiety, and other kinds of emotion can profoundly influence key elements of cognition, including selective attention, working memory, and cognitive control. Often, this influence persists beyond the duration of transient emotional challenges, partially reflecting the slower molecular dynamics of catecholamine and hormonal neurochemistry. In turn, circuits involved in attention, executive control, and working memory contribute to the regulation of emotion. Indeed, there is compelling evidence that brain territories and psychological processes commonly associated with cognition, such as the dorsolateral prefrontal cortex and working memory, play a central role in emotion. Furthermore, putatively emotional and cognitive regions influence one another via a complex web of connections in ways that jointly contribute to adaptive and maladaptive behavior.

Но стрелять не понадобилось. Халохот был мертв. Беккер отшвырнул пистолет и без сил опустился на ступеньку. Впервые за целую вечность он почувствовал, что глаза его застилают слезы, и зажмурился, прогоняя влажную пелену. Он знал, что для эмоций еще будет время, а теперь пора отправляться домой.

    Within the past decade or so, our knowledge regarding reward systems in the brain, the nature of their interactions with other brain systems, and their influence on a wide range of cognitive and emotional processes has grown substantially.
