Vignette (psychology)
A vignette in psychological and sociological experiments presents a hypothetical situation, to which research participants respond thereby revealing their perceptions, values, social norms or impressions of events. Peter Rossi and colleagues developed a framework for creating vignettes by systematically combining predictor variables in order to dissect the effects of the variables on dependent variables. For example, to study normative judgments of family status, "there might be 10 levels of income; 50 head-of-household occupations, and 50 occupations for spouses; two races, white and black; and ten levels of family size". Since this approach can lead to huge universes of stimuli – half a million in the example – Rossi proposed drawing small random samples from the universe of stimuli for presentation to individual respondents, and pooling judgments by multiple respondents in order to sample the universe adequately. Main effects of predictor variables then can be assessed, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Social Psychology
Social psychology is the scientific study of how thoughts, feelings, and behaviors are influenced by the real or imagined presence of other people or by social norms. Social psychologists typically explain human behavior as a result of the relationship between mental states and social situations, studying the social conditions under which thoughts, feelings, and behaviors occur, and how these variables influence social interactions. History Although issues in social psychology have been discussed in philosophy for much of human history, the scientific discipline of social psychology formally began in the late 19th to early 20th century. 19th century In the 19th century, social psychology began to emerge from the larger field of psychology. At the time, many psychologists were concerned with developing concrete explanations for the different aspects of human nature. They attempted to discover concrete cause-and-effect relationships that explained social interactions. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dependent And Independent Variables
Dependent and independent variables are variables in mathematical modeling, statistical modeling and experimental sciences. Dependent variables receive this name because, in an experiment, their values are studied under the supposition or demand that they depend, by some law or rule (e.g., by a mathematical function), on the values of other variables. Independent variables, in turn, are not seen as depending on any other variable in the scope of the experiment in question. In this sense, some common independent variables are time, space, density, mass, fluid flow rate, and previous values of some observed value of interest (e.g. human population size) to predict future values (the dependent variable). Of the two, it is always the dependent variable whose variation is being studied, by altering inputs, also known as regressors in a statistical context. In an experiment, any variable that can be attributed a value without attributing a value to any other variable is called an in ...

Methods In Sociology
Method ( grc, μέθοδος, methodos) literally means a pursuit of knowledge, investigation, mode of prosecuting such inquiry, or system. In recent centuries it more often means a prescribed process for completing a task. It may refer to: *Scientific method, a series of steps, or collection of methods, taken to acquire knowledge *Method (computer programming), a piece of code associated with a class or object to perform a task *Method (patent), under patent law, a protected series of steps or acts *Methodology, comparison or study and critique of individual methods that are used in a given discipline or field of inquiry *''Discourse on the Method'', a philosophical and mathematical treatise by René Descartes * ''Methods'' (journal), a scientific journal covering research on techniques in the experimental biological and medical sciences Arts *Method (music), a kind of textbook to help students learning to play a musical instrument * ''Method'' (2004 film), a 2004 film directed by ...

Everyday Life
Everyday life, daily life or routine life comprises the ways in which people typically act, think, and feel on a daily basis. Everyday life may be described as mundane, routine, natural, habitual, or normal. Human diurnality means most people sleep at least part of the night and are active in daytime. Most eat two or three meals in a day. Working time (apart from shift work) mostly involves a daily schedule, beginning in the morning. This produces the daily rush hours experienced by many millions, and the drive time focused on by radio broadcasters. Evening is often leisure time. Bathing every day is a custom for many. Beyond these broad similarities, lifestyles vary and different people spend their days differently. For example, nomadic life differs from sedentism, and among the sedentary, urban people live differently from rural folk. Differences in the lives of the rich and the poor, or between laborers and intellectuals, may go beyond their working hours. Children an ...

Affect Control Theory
In control theory, affect control theory proposes that individuals maintain affective meanings through their actions and interpretations of events. The activity of social institutions occurs through maintenance of culturally based affective meanings. Affective meaning Besides a denotative meaning, every concept has an affective meaning, or connotation, that varies along three dimensions: evaluation – goodness versus badness, potency – powerfulness versus powerlessness, and activity – liveliness versus torpidity. Affective meanings can be measured with semantic differentials yielding a three-number profile indicating how the concept is positioned on evaluation, potency, and activity (EPA). Osgood demonstrated that an elementary concept conveyed by a word or idiom has a normative affective meaning within a particular culture. A stable affective meaning derived either from personal experience or from cultural inculcation is called a sentiment, or fundamental affective meaning, ...

Impression Formation
Impression formation in social psychology refers to the processes by which different pieces of knowledge about another are combined into a global or summary impression. Social psychologist Solomon Asch is credited with the seminal research on impression formation and conducted research on how individuals integrate information about personality traits. Two major theories have been proposed to explain how this process of integration takes place. The Gestalt approach views the formation of a general impression as the sum of several interrelated impressions. As an individual seeks to form a coherent and meaningful impression of another individual, previous impressions significantly influence the interpretation of subsequent information. In contrast to the Gestalt approach, the cognitive algebra approach asserts that individuals' experiences are combined with previous evaluations to form a constantly changing impression of a person. A related area to impression formation is the study of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Main Effect
In the design of experiments and analysis of variance, a main effect is the effect of an independent variable on a dependent variable averaged across the levels of any other independent variables. The term is frequently used in the context of factorial designs and regression models to distinguish main effects from interaction Interaction is action that occurs between two or more objects, with broad use in philosophy and the sciences. It may refer to: Science * Interaction hypothesis, a theory of second language acquisition * Interaction (statistics) * Interactions o ... effects. Relative to a factorial design, under an analysis of variance, a main effect test will test the hypotheses expected such as H0, the null hypothesis. Running a hypothesis for a main effect will test whether there is evidence of an effect of different treatments. However a main effect test is nonspecific and will not allow for a localization of specific mean pairwise comparisons (simple effects). A main e ...

Sample (statistics)
In statistics, quality assurance, and survey methodology, sampling is the selection of a subset (a statistical sample) of individuals from within a statistical population to estimate characteristics of the whole population. Statisticians attempt to collect samples that are representative of the population in question. Sampling has lower costs and faster data collection than measuring the entire population and can provide insights in cases where it is infeasible to measure an entire population. Each observation measures one or more properties (such as weight, location, colour or mass) of independent objects or individuals. In survey sampling, weights can be applied to the data to adjust for the sample design, particularly in stratified sampling. Results from probability theory and statistical theory are employed to guide the practice. In business and medical research, sampling is widely used for gathering information about a population. Acceptance sampling is used to determine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Factorial Experiment
In statistics, a full factorial experiment is an experiment whose design consists of two or more factors, each with discrete possible values or "levels", and whose experimental units take on all possible combinations of these levels across all such factors. A full factorial design may also be called a fully crossed design. Such an experiment allows the investigator to study the effect of each factor on the response variable, as well as the effects of interactions between factors on the response variable. For the vast majority of factorial experiments, each factor has only two levels. For example, with two factors each taking two levels, a factorial experiment would have four treatment combinations in total, and is usually called a ''2×2 factorial design''. In such a design, the interaction between the variables is often the most important. This applies even to scenarios where a main effect and an interaction is present. If the number of combinations in a full factorial design i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Social Psychology (sociology)
In sociology, social psychology (also known as sociological social psychology) studies the relationship between the individual and society. Although studying many of the same substantive topics as its counterpart in the field of psychology, sociological social psychology places relatively more emphasis on the influence of social structure and culture on individual outcomes, such as personality, behavior, and one's position in social hierarchies. Researchers broadly focus on higher levels of analysis, directing attention mainly to groups and the arrangement of relationships among people. This subfield of sociology is broadly recognized as having three major perspectives: Symbolic interactionism, social structure and personality, and structural social psychology. Some of the major topics in this field include social status, structural power, sociocultural change, social inequality and prejudice, leadership and intra-group behavior, social exchange, group conflict, impression ...

Peter Rossi
Peter Henry Rossi (December 27, 1921 – October 7, 2006) was a prominent sociologist best known for his research on the origin of homelessness, and documenting the changing face of American homelessness in the 1980s. Rossi was also known for his work devising ways to evaluate federally funded initiatives in education, health services, crime control, and housing. He influentially applied his sociological expertise to affect related policy-making and funding agencies. At his death, he was the Stuart A. Rice professor emeritus of Sociology and the director emeritus of the Social and Demographic Research Institute (SADRI) at the University of Massachusetts Amherst. Biography Rossi was born December 27, 1921, in Corona, Queens, New York City, New York, to Italian immigrant parents. He graduated from the City College of New York with a degree in sociology in 1943. After graduating, he intended on going into social work; however, he enlisted in the Army in 1943, and served in the 100th ...
