Error Management
Error management theory (EMT) is an approach to perception and cognitive bias, cognition biases originally coined by David Buss and Martie Haselton. Error management training is a related area that uses this theory. The objective of it is to encourage trainees to make errors and encourage them in reflection to understand the causes of those errors and to identify suitable strategies to avoid making them in future. Various biases in thinking and decision-making have been highlighted by Daniel Kahneman and have been shown to cause cognitive errors in psychological and economic decisions. Cognitive biases in error management theory refer to biases and heuristics that have undergone positive selection because they confer evolutionary benefits. According to this theory, recurrent cost asymmetries between two types of errors Type 1 and 2 over evolutionary time should result in a bias to make the less costly error (i.e., adaptive rationality leads to cognitive biases).

Cognitive Bias
A cognitive bias is a systematic pattern of deviation from norm (philosophy), norm or rationality in judgment. Individuals create their own "subjective reality" from their perception of the input. An individual's construction of reality, not the Objectivity (philosophy), objective input, may dictate their behavior in the world. Thus, cognitive biases may sometimes lead to perceptual distortion, inaccurate judgment, illogical interpretation, and irrationality. While cognitive biases may initially appear to be negative, some are adaptive. They may lead to more effective actions in a given context. Furthermore, allowing cognitive biases enables faster decisions which can be desirable when timeliness is more valuable than accuracy, as illustrated in Heuristic (psychology), heuristics. Other cognitive biases are a "by-product" of human processing limitations, resulting from a lack of appropriate mental mechanisms (bounded rationality), the impact of an individual's constitution and bi ...

Postmenopausal
Menopause, also known as the climacteric, is the time when menstrual periods permanently stop, marking the end of the reproductive stage for the female human. It typically occurs between the ages of 45 and 55, although the exact timing can vary. Menopause is usually a natural change related to a decrease in circulating blood estrogen levels. It can occur earlier in those who smoke tobacco. Other causes include surgery that removes both ovaries, some types of chemotherapy, or anything that leads to a decrease in hormone levels. At the physiological level, menopause happens because of a decrease in the ovaries' production of the hormones estrogen and progesterone. While typically not needed, measuring hormone levels in the blood or urine can confirm a diagnosis. Menopause is the opposite of menarche, the time when periods start. In the years before menopause, a woman's periods typically become irregular, which means that periods may be longer or shorter in duration, or be ...

Evolutionary Psychology
Evolutionary psychology is a theoretical approach in psychology that examines cognition and behavior from a modern evolutionary perspective. It seeks to identify human psychological adaptations with regard to the ancestral problems they evolved to solve. In this framework, psychological traits and mechanisms are either functional products of natural selection, natural and sexual selection in human evolution, sexual selection or non-adaptive Spandrel (biology), by-products of other adaptive traits. Adaptationist thinking about Physiology, physiological mechanisms, such as the heart, Lung, lungs, and the liver, is common in evolutionary biology. Evolutionary psychologists apply the same thinking in psychology, arguing that just as the heart evolved to pump blood, the liver evolved to detoxify poisons, and the kidneys evolved to filter turbid fluids there is modularity of mind in that different psychological mechanisms evolved to solve different adaptive problems. These evolutionary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evolution & Human Behavior
''Evolution and Human Behavior'' is a bimonthly peer-reviewed academic journal covering research in which evolutionary perspectives are brought to bear on the study of human behavior, ranging from evolutionary psychology to evolutionary anthropology and cultural evolution. It is primarily a scientific journal, but articles from scholars in the humanities are also published. Papers reporting on theoretical and empirical work on other species may be included if their relevance to the human animal is apparent. The journal was established in 1980, and beginning with Volume 18 in 1997 has been published by Elsevier on behalf of the Human Behavior and Evolution Society. The editor-in-chief is Debra Lieberman ( University of Miami). Among more than 300 other psychology and medical journals, ''Evolution and Human Behavior'' has adopted result-blind peer review (i.e. where studies are accepted not on the basis of their findings and after the studies are completed, but before the studi ...

Reinforcement Learning
Reinforcement learning (RL) is an interdisciplinary area of machine learning and optimal control concerned with how an intelligent agent should take actions in a dynamic environment in order to maximize a reward signal. Reinforcement learning is one of the three basic machine learning paradigms, alongside supervised learning and unsupervised learning. Reinforcement learning differs from supervised learning in not needing labelled input-output pairs to be presented, and in not needing sub-optimal actions to be explicitly corrected. Instead, the focus is on finding a balance between exploration (of uncharted territory) and exploitation (of current knowledge) with the goal of maximizing the cumulative reward (the feedback of which might be incomplete or delayed). The search for this balance is known as the exploration–exploitation dilemma. The environment is typically stated in the form of a Markov decision process (MDP), as many reinforcement learning algorithms use dyn ...

Animistic Fallacy
The animistic fallacy is the informal fallacy of arguing that an event or situation necessarily arose because someone intentionally acted to cause it. While it could be that someone set out to effect a specific goal, the fallacy appears in an argument that states this ''must'' be the case. The name of the fallacy comes from the animistic belief that changes in the physical world are the work of conscious spirits. __NOTOC__ Examples Thomas Sowell in his book '' Knowledge and Decisions'' (1980) presents several arguments as examples of the animistic fallacy: * that people earn wealth always because of superior choices * that central planning is necessary to prevent chaos in society Sowell repeatedly dismisses the necessity that order comes from design, and notes that fallacious animistic arguments tend to provide explanations that require comparatively little time to implement. In this light he contrasts the six-day creation of the world described in the Bible to the developme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Speed Dating
Speed dating is a formalized matchmaking process with the purpose of encouraging eligible singles to meet new potential partners in a very short period of time, so that interested pairs can continue meeting each other after the event. Organization Usually, advance registration is required for speed dating events. Participants are rotated to meet each other over a series of short "Dating, dates" typically lasting from three to eight minutes depending on the organization running the event. At the end of each interval a signal (e.g., a ringing bell, glass clinks or a whistle blow) is given to alert participants to move on to the next date. When the event concludes, participants can submit a list to the organizers of candidates they would like to share their contact information with. The organizers will forward the contact information if both participants included each other on the list. Contact information cannot be exchanged during the initial meeting to reduce pressure when acc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sexual Harassment
Sexual harassment is a type of harassment based on the sex or gender of a victim. It can involve offensive sexist or sexual behavior, verbal or physical actions, up to bribery, coercion, and assault. Harassment may be explicit or implicit, with some examples including making unwanted sexually colored remarks, actions that insult and degrade by gender, showing pornography, demanding or requesting sexual favors, offensive sexual advances, and any other unwelcome physical, verbal, or non-verbal (sometimes provocative) conduct based on sex. Sexual harassment includes a range of actions from verbal transgressions to sexual abuse or sexual assault, assault.Dziech, Billie Wright; Weiner, Linda. ''The Lecherous Professor: Sexual Harassment on Campus''. Chicago Illinois: University of Illinois Press, 1990. ; Boland, 2002 Harassment can occur in many different social settings such as the workplace, the home, school, or religious institutions. Harassers or victims can be of any gender. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mate Choice
Mate choice is one of the primary mechanisms under which evolution can occur. It is characterized by a "selective response by animals to particular stimuli" which can be observed as behavior.Bateson, Paul Patrick Gordon. "Mate Choice." Mate Choice, Cambridge University Press, 1985 In other words, before an animal engages with a potential mate, they first evaluate various aspects of that mate which are indicative of quality—such as the resources or phenotypes they have—and evaluate whether or not those particular Phenotypic trait, trait(s) are somehow beneficial to them. The evaluation will then incur a response of some sort. These mechanisms are a part of evolutionary change because they operate in a way that causes the qualities that are desired in a mate to be more frequently passed on to each generation over time. For example, if female peacocks desire mates who have a colourful plumage, then this trait will increase in frequency over time as male peacocks with a colourful ...

David Buss
David Michael Buss (born April 14, 1953) is an American evolutionary psychologist at the University of Texas at Austin, researching human sex differences in mate selection. He is considered one of the founders of evolutionary psychology. Biography Buss earned his PhD in psychology at University of California, Berkeley in 1981. Before becoming a professor at the University of Texas, he was assistant professor for four years at Harvard University and a professor at the University of Michigan for eleven years. The primary topics of his research include male mating strategies, conflict between the sexes, social status, social reputation, prestige, the emotion of jealousy, homicide, anti-homicide defenses, and—most recently—stalking. All of these are approached from an evolutionary perspective. Buss is the author of more than 200 scientific articles and has won many awards, including an APA Distinguished Scientific Award for Early Career Contribution to Psychology in 1988 and ...

False Negative
A false positive is an error in binary classification in which a test result incorrectly indicates the presence of a condition (such as a disease when the disease is not present), while a false negative is the opposite error, where the test result incorrectly indicates the absence of a condition when it is actually present. These are the two kinds of errors in a binary test, in contrast to the two kinds of correct result (a and a ). They are also known in medicine as a false positive (or false negative) diagnosis, and in statistical classification as a false positive (or false negative) error. In statistical hypothesis testing, the analogous concepts are known as type I and type II errors, where a positive result corresponds to rejecting the null hypothesis, and a negative result corresponds to not rejecting the null hypothesis. The terms are often used interchangeably, but there are differences in detail and interpretation due to the differences between medical testing and sta ...
