Affect Heuristic
The affect heuristic is a heuristic, a mental shortcut that allows people to make decisions and solve problems quickly and efficiently, in which current emotion—fear, pleasure, surprise, etc.—influences decisions. In other words, it is a type of heuristic in which emotional response, or " affect" in psychological terms, plays a lead role. It is a subconscious process that shortens the decision-making process and allows people to function without having to complete an extensive search for information. It is shorter in duration than a mood, occurring rapidly and involuntarily in response to a stimulus. Reading the words "lung cancer" usually generates an affect of dread, while reading the words "mother's love" usually generates a feeling of affection and comfort. The affect heuristic is typically used while judging the risks and benefits of something, depending on the positive or negative feelings that people associate with a stimulus. It is the equivalent of "going with your ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heuristics In Judgment And Decision-making
Heuristics is the process by which humans use mental short cuts to arrive at decisions. Heuristics are simple strategies that humans, animals, organizations, and even machines use to quickly form judgments, make decisions, and find solutions to complex problems. Often this involves focusing on the most relevant aspects of a problem or situation to formulate a solution. While heuristic processes are used to find the answers and solutions that are ''most'' likely to work or be correct, they are not always right or the most accurate. Judgments and decisions based on heuristics are simply good enough to satisfy a pressing need in situations of uncertainty, where information is incomplete. In that sense they can differ from answers given by logic and probability. The economist and cognitive psychologist Herbert A. Simon introduced the concept of heuristics in the 1950s, suggesting there were limitations to rational decision making. In the 1970s, psychologists Amos Tversky and Daniel ...

Risk Perception
Risk perception is the subjective judgement that people make about the characteristics and severity of a risk. Risk perceptions are different for the real risks since they are affected by a wide range of affective (emotions, feelings, moods, etc.), cognitive (gravity of events, media coverage, risk-mitigating measures, etc.), contextual (framing of risk information, availability of alternative information sources, etc.), and individual (personality traits, previous experience, age, etc.) factors. Several theories have been proposed to explain why different people make different estimates of the dangerousness of risks. Three major families of theory have been developed: psychology approaches (heuristics and cognitive), anthropology/sociology approaches (cultural theory) and interdisciplinary approaches (social amplification of risk framework). Early theories The study of risk perception arose out of the observation that experts and lay people often disagreed about how risky various ...

Feeling
Feelings are subjective self-contained phenomenal experiences. According to the ''APA Dictionary of Psychology'', a feeling is "a self-contained phenomenal experience"; and feelings are "subjective, evaluative, and independent of the sensations, thoughts, or images evoking them". The term ''feeling'' is closely related to, but not the same as emotion. "Feeling" may for instance refer to the conscious subjective experience of emotions. The study of subjective experiences is referred to as phenomenology. The discipline of psychotherapy generally involves a therapist helping a client understand, articulate and learn to effectively regulate their own feelings and ultimately take responsibility for their experience of the world. Feelings are sometimes held to be characteristic of embodied consciousness. The English noun ''feelings'' may generally refer to any degree of subjectivity in perception or sensation. However, feelings often refer to an individual sense of well-being (perha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Effects Of Climate Change
The effects of climate change impact the physical environment, ecosystems and human societies. The environmental effects of climate change are broad and far-reaching. They affect the water cycle, oceans, sea and land ice (glaciers), sea level, as well as weather and climate extreme events. The changes in climate are not uniform across the Earth. In particular, most land areas have warmed faster than most ocean areas, and the Arctic is warming faster than most other regions. The regional changes vary: at high latitudes it is the average temperature that is increasing, while for the oceans and tropics it is in particular the rainfall and the water cycle where changes are observed. The magnitude of future impacts of climate change can be reduced by climate change mitigation and adaptation. Climate change has degraded land by raising temperatures, drying soils and increasing wildfire risk. Recent warming has strongly affected natural biological systems. Species worldwide are mig ...

Dual Process Theory
In psychology, a dual process theory provides an account of how thought can arise in two different ways, or as a result of two different processes. Often, the two processes consist of an implicit (automatic), unconscious process and an explicit (controlled), conscious process. Verbalized explicit processes or attitudes and actions may change with persuasion or education; though implicit process or attitudes usually take a long amount of time to change with the forming of new habits. Dual process theories can be found in social, personality, cognitive, and clinical psychology. It has also been linked with economics via prospect theory and behavioral economics, and increasingly in sociology through cultural analysis. History The foundations of dual process theory likely comes from William James. He believed that there were two different kinds of thinking: associative and true reasoning. James theorized that empirical thought was used for things like art and design work. For James, im ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Somatic Marker Hypothesis
The somatic marker hypothesis, formulated by Antonio Damasio and associated researchers, proposes that emotional processes guide (or bias) behavior, particularly decision-making. '' Descartes' Error'' "Somatic markers" are feelings in the body that are associated with emotions, such as the association of rapid heartbeat with anxiety or of nausea with disgust. According to the hypothesis, somatic markers strongly influence subsequent decision-making. Within the brain, somatic markers are thought to be processed in the ventromedial prefrontal cortex (VMPFC) and the amygdala. The hypothesis has been tested in experiments using the Iowa gambling task. Background In economic theory, human decision-making is often modeled as being devoid of emotions, involving only logical reasoning based on cost-benefit calculations. In contrast, the somatic marker hypothesis proposes that emotions play a critical role in the ability to make fast, rational decisions in complex and uncertain situation ...

Antonio Damasio
Antonio Damasio ( pt, António Damásio) is a Portuguese-American neuroscientist. He is currently the David Dornsife Chair in Neuroscience, as well as Professor of Psychology, Philosophy, and Neurology, at the University of Southern California, and, additionally, an adjunct professor at the Salk Institute. He was previously the chair of neurology at the University of Iowa for 20 years. Damasio heads the Brain and Creativity Institute, and has authored several books: his next to latest work, ''Self Comes to Mind: Constructing the Conscious Brain'' (2010), explores the relationship between the brain and consciousness. Damasio's research in neuroscience has shown that emotions play a central role in social cognition and decision-making. Life and work During the 1960s, Damasio studied medicine at the University of Lisbon Medical School, where he also did his neurological residency and completed his doctorate in 1974. For part of his studies, he researched behavioral neurology unde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Illogical
As the study of argument is of clear importance to the reasons that we hold things to be true, logic is of essential importance to rationality. Arguments may be logical if they are "conducted or assessed according to strict principles of validity", while they are rational according to the broader requirement that they are based on reason and knowledge. Logic and rationality have each been taken as fundamental concepts in philosophy. They are not one of the same thing. Philosophical rationalism in its most extreme form is the doctrine that knowledge can ultimately be founded on pure reason, while logicism is the doctrine that mathematical concepts, among others are reducible to pure logic. Forms of reasoning Deductive reasoning concerns the logical consequence of given premises. On a narrow conception of logic, logic concerns just deductive reasoning, although such a narrow conception controversially excludes most of what is called informal logic from the discipline. Other forms of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Judgment
Judgement (or US spelling judgment) is also known as ''adjudication'', which means the evaluation of evidence to decision-making, make a decision. Judgement is also the ability to make considered decisions. The term has at least five distinct uses. Aristotle suggested we think of the ''opposite'' of different uses of a term, if one exists, to help determine if the uses are really different. Some opposites will be included here to help demonstrate that their uses are really distinct: * Informal – opinions expressed as facts. * Informal and psychological – used in reference to the quality of Mind, cognitive faculties and adjudicational capabilities of particular individuals, typically called ''wisdom'' or ''discernment''. The opposites are ''foolishness'' or ''indiscretion''. * Formal - the mental act of affirming or denying one thing of another through comparison. Judgements are communicated to others using agreed-upon ''terms'' in the form of words or algebraic symbols as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theory
A theory is a rational type of abstract thinking about a phenomenon, or the results of such thinking. The process of contemplative and rational thinking is often associated with such processes as observational study or research. Theories may be scientific, belong to a non-scientific discipline, or no discipline at all. Depending on the context, a theory's assertions might, for example, include generalized explanations of how nature works. The word has its roots in ancient Greek, but in modern use it has taken on several related meanings. In modern science, the term "theory" refers to scientific theories, a well-confirmed type of explanation of nature, made in a way consistent with the scientific method, and fulfilling the criteria required by modern science. Such theories are described in such a way that scientific tests should be able to provide empirical support for it, or empirical contradiction ("falsify") of it. Scientific theories are the most reliable, rigorous, and compr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emotion
Emotions are mental states brought on by neurophysiological changes, variously associated with thoughts, feelings, behavioral responses, and a degree of pleasure or displeasure. There is currently no scientific consensus on a definition. Emotions are often intertwined with mood, temperament, personality, disposition, or creativity. Research on emotion has increased over the past two decades with many fields contributing including psychology, medicine, history, sociology of emotions, and computer science. The numerous theories that attempt to explain the origin, function and other aspects of emotions have fostered more intense research on this topic. Current areas of research in the concept of emotion include the development of materials that stimulate and elicit emotion. In addition, PET scans and fMRI scans help study the affective picture processes in the brain. From a mechanistic perspective, emotions can be defined as "a positive or negative experience that is as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Affection
Affection or fondness is a "disposition or state of mind or body" that is often associated with a feeling or type of love. It has given rise to a number of branches of philosophy and psychology concerning emotion, disease, influence, and state of being. "Affection" is popularly used to denote a feeling or type of love, amounting to more than goodwill or friendship. Writers on ethics generally use the word to refer to distinct states of feeling, both lasting and spasmodic. Some contrast it with '' passion'' as being free from the distinctively sensual element. Even a very simple demonstration of affection can have a broad variety of emotional reactions, from embarrassment, to disgust, pleasure, and annoyance. It also has a different physical effect on the giver and the receiver. Restricted definition More specifically, the word has been restricted to emotional states, the object of which is a living thing such as a human or animal. Affection is compared with passion, from th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
