Cognition and Emotion
Decision making involves choosing among alternatives and judgment play a very important role in this process.Mood states influence an individual’s attitude towards risk-taking and this in turn affects their decisions.Anxiety is associated with concerns and worries about future threats.Sadness is associated with an absence of positive affect to a greater extent when compared to anxiety.Schwarz concluded that being in a sad mood causes people to use a processing strategy in which much attention is paid to details.De Vries et al. hypothesized that people are most satisfied with their decision making when they have made use of their preferred processing strategy.Individuals in a positive or good mood exhibit a stronger optimistic bias than those in a neutral or negative mood.Cognitive neuroscience provides an alternative way of understanding the role played by emotional factors in judgment and decision making.Esterbrook’s Hypothesis proposes that the range of environmental cues reduces as arousal or anxiety increases leading to what is commonly referred to as tunnel vision.According to Levine and Edelstein emotion enhances our memory for information central to our current goals but impairs it for peripheral or unimportant information.Most people find themselves recalling far more negative or unpleasant memories when in a negative mood and positive or pleasant memories when they are in a positive mood.Flashbulb memories seem especially vivid because they typically refer to distinctive events and they suffer little interference from other memories.The strong effects of emotion memory are mediated by several different regions of the brain, most importantly the amygdala.The Urbach-Wiethe Disease is a disease in which the amygdala and the adjacent areas of the brain are destroyed and there is a reduction in the intensity of emotional experiences.The amygdala is involved in memory for positive information as well as negative information.
