Richard Crutchfield
Richard Stanley Crutchfield (June 20, 1912 – July 19, 1977) was an American experimental, personality and social psychologist who, in the 1930s, was instrumental in moving psychology from a tradition of single-factor experiments to an experimental design based on analysis of variance and covariance. Crutchfield co-authored two influential texts with David Krech. The first is the very successful social psychology textbook ''Theory and Problems of Social Psychology'' (1948). The second was an introductory psychology text, first published in 1958, ''Elements of Psychology'', which has been widely used and has numerous editions and derivatives. In the 1950s, Crutchfield's work helped to establish the linkage between cognitive-perceptual processes and significant facets of personality. His best-known research was a series of investigations of the nature of conformity in interpersonal sphere of social psychology, which were published during the height of what is known in psychologi ...

David Krech
David Krech (March 27, 1909 – July 14, 1977) was a Polish-born American experimental and social psychologist who lectured predominately at the University of California, Berkeley. Throughout his education and career endeavors, Krech was with many psychologists including Edward Tolman, Karl Lashley, and Rensis Likert. Krech was born as Yitzhok-Eizik Krechevsky, but changed his name to Isadore Krechevsky upon emigration to the United States in 1913. His name was changed to David Krech in 1943 when he married Hilda Sidonie Gruenberg. Krech did this because he did not want his future son(s) to be labeled with a Jewish name that had held him back in both academic and career pursuits. Krech extensively researched rats in several university laboratories and found evidence that supported the localization theory of the brain. Later in his career, Krech became interested in the topic of Social Psychology which led him to publishing ''Theory and Problems of Social Psychology'' in 1948 wit ...

Experimental Psychologists
An experiment is a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in goal and scale but always rely on repeatable procedure and logical analysis of the results. There also exist natural experimental studies. A child may carry out basic experiments to understand how things fall to the ground, while teams of scientists may take years of systematic investigation to advance their understanding of a phenomenon. Experiments and other types of hands-on activities are very important to student learning in the science classroom. Experiments can raise test scores and help a student become more engaged and interested in the material they are learning, especially when used over time. Experiments can vary from personal and informal natural comparisons (e. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crutchfield Situation
The Crutchfield Situation was an experimental procedure and apparatus created by Richard Crutchfield, Richard S. Crutchfield in 1955 to study conformity. Essentially, the Crutchfield Situation was an attempt to improve upon the methodology employed in the Asch conformity experiments. One of the major criticisms concerning the Asch studies was the need for many accomplices (i.e., confederates) in order to study one participant. According to Forsyth, an additional criticism of Asch's design was that “participants in the Asch studies stated their choices aloud under the watchful eyes of all the other members, and this procedure likely increased their feelings of embarrassment and of being evaluated.” Crutchfield's design eliminated the need for many confederates, and protected against the potential of subjects’ feeling embarrassed by stating answers aloud, by placing participants into individual side-by-side cubicles. The partition walls in each cubicle blocked participants fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Tolman
Edward Chace Tolman (April 14, 1886 – November 19, 1959) was an American psychologist and a professor of psychology at the University of California, Berkeley. Through Tolman's theories and works, he founded what is now a branch of psychology known as purposive behaviorism. Tolman also promoted the concept known as latent learning first coined by Blodgett (1929). A ''Review of General Psychology'' survey, published in 2002, ranked Tolman as the 45th most cited psychologist of the 20th century. Tolman was one of the leading figures in protecting academic freedom during the McCarthy era in early 1950s. In recognition of Tolman's contributions to both the development of psychology and academic freedom, the Education and Psychology building on Berkeley campus, the "Tolman Hall", was named after him. Early life Born in West Newton, Massachusetts, brother of Caltech physicist Richard Chace Tolman, Edward C. Tolman studied at the Massachusetts Institute of Technology, receiving B.S. i ...

Interpersonal
The concept of interpersonal relationship involves social associations, connections, or affiliations between two or more people. Interpersonal relationships vary in their degree of intimacy or self-disclosure, but also in their duration, in their reciprocity and in their power distribution, to name only a few dimensions. The context can vary from family or kinship relations, friendship, marriage, relations with associates, work, clubs, neighborhoods, and places of worship. Relationships may be regulated by law, custom, or mutual agreement, and form the basis of social groups and of society as a whole. Interpersonal relationships are created by people's interactions with one another in social situations. This association of interpersonal relations being based on social situation has inference since in some degree love, solidarity, support, regular business interactions, or some other type of social connection or commitment. Interpersonal relationships thrive through equitable a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conformity
Conformity is the act of matching attitudes, beliefs, and behaviors to group norms, politics or being like-minded. Norms are implicit, specific rules, shared by a group of individuals, that guide their interactions with others. People often choose to conform to society rather than to pursue personal desires - because it is often easier to follow the path others have made already, rather than forging a new one. Thus, conformity is sometimes a product of group communication. This tendency to conform occurs in small groups and/or in society as a whole and may result from subtle unconscious influences (predisposed state of mind), or from direct and overt social pressure. Conformity can occur in the presence of others, or when an individual is alone. For example, people tend to follow social norms when eating or when watching television, even if alone. The Asch Conformity Experiment demonstrates how much influence conformity has on people. In a laboratory experiment, Asch asked 50 ma ...

Personality
Personality is the characteristic sets of behaviors, cognitions, and emotional patterns that are formed from biological and environmental factors, and which change over time. While there is no generally agreed-upon definition of personality, most theories focus on motivation and psychological interactions with the environment one is surrounded by. Trait-based personality theories, such as those defined by Raymond Cattell, define personality as traits that predict an individual's behavior. On the other hand, more behaviorally-based approaches define personality through learning and habits. Nevertheless, most theories view personality as relatively stable. The study of the psychology of personality, called personality psychology, attempts to explain the tendencies that underlie differences in behavior. Psychologists have taken many different approaches to the study of personality, including biological, cognitive, learning, and trait-based theories, as well as psychodynamic, and hum ...

Perceptual Psychology
Perceptual psychology is a subfield of cognitive psychology that concerns the conscious and unconscious innate aspects of the human cognitive system: perception. A pioneer of the field was James J. Gibson. One major study was that of affordances, i.e. the perceived utility of objects in, or features of, one's surroundings. According to Gibson, such features or objects were perceived as affordances and not as separate or distinct objects in themselves. This view was central to several other fields as software user interface and usability engineering, environmentalism in psychology, and ultimately to political economy where the perceptual view was used to explain the omission of key inputs or consequences of economic transactions, i.e. resources and wastes. Gerard Egan and Robert Bolton explored areas of interpersonal interactions based on the premise that people act in accordance with their perception of a given situation. While behaviour is obvious, a person's thoughts and feelings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Textbook
A textbook is a book containing a comprehensive compilation of content in a branch of study with the intention of explaining it. Textbooks are produced to meet the needs of educators, usually at educational institutions. Schoolbooks are textbooks and other books used in schools. Today, many textbooks are published in both print and digital formats. History The history of textbooks dates back to ancient civilizations. For example, Ancient Greeks wrote educational texts. The modern textbook has its roots in the mass production made possible by the printing press. Johannes Gutenberg himself may have printed editions of ''Ars Minor'', a schoolbook on Latin grammar by Aelius Donatus. Early textbooks were used by tutors and teachers (e.g. alphabet books), as well as by individuals who taught themselves. The Greek philosopher Socrates lamented the loss of knowledge because the media of transmission were changing. Before the invention of the Greek alphabet 2,500 years ago, knowledge ...

Covariance
In probability theory and statistics, covariance is a measure of the joint variability of two random variables. If the greater values of one variable mainly correspond with the greater values of the other variable, and the same holds for the lesser values (that is, the variables tend to show similar behavior), the covariance is positive. In the opposite case, when the greater values of one variable mainly correspond to the lesser values of the other, (that is, the variables tend to show opposite behavior), the covariance is negative. The sign of the covariance therefore shows the tendency in the linear relationship between the variables. The magnitude of the covariance is not easy to interpret because it is not normalized and hence depends on the magnitudes of the variables. The normalized version of the covariance, the correlation coefficient, however, shows by its magnitude the strength of the linear relation. A distinction must be made between (1) the covariance of two random ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
