Cognitive Social Structures
Cognitive social structures (CSS) is the focus of research that investigates how individuals perceive their own social structure (e.g. members of an organization, friend group, hierarchy, company employees, etc.). It is part of social network research and uses social network analysis to understand how various factors affect one's cognitive representation of the network (i.e. the individual's belief of who is connected to whom). Importantly, an individual's perception of the network may be different than reality. In fact, these differences between the perceived network and the actual network are the focus of many studies that seek insight into how we think about others and our relationships. Overview In 1987, David Krackhardt discussed the study of cognitive social structures in an article that defined the term and outlined its uses in social network research. Social structures are defined by a set of individual members and the relations between those members. The study of cogn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Social Structure
In the social sciences, social structure is the aggregate of patterned social arrangements in society that are both emergent from and determinant of the actions of individuals. Likewise, society is believed to be grouped into structurally related groups or sets of roles, with different functions, meanings, or purposes. Examples of social structure include family, religion, law, economy, and class. It contrasts with "social system", which refers to the parent structure in which these various structures are embedded. Thus, social structures significantly influence larger systems, such as economic systems, legal systems, political systems, cultural systems, etc. Social structure can also be said to be the framework upon which a society is established. It determines the norms and patterns of relations between the various institutions of the society. Since the 1920s, the term has been in general use in social science, especially as a variable whose sub-components needed to be disti ...

Small-world Network
A small-world network is a type of mathematical graph in which most nodes are not neighbors of one another, but the neighbors of any given node are likely to be neighbors of each other and most nodes can be reached from every other node by a small number of hops or steps. Specifically, a small-world network is defined to be a network where the typical distance ''L'' between two randomly chosen nodes (the number of steps required) grows proportionally to the logarithm of the number of nodes ''N'' in the network, that is: :L \propto \log N while the global clustering coefficient is not small. In the context of a social network, this results in the small world phenomenon of strangers being linked by a short chain of acquaintances. Many empirical graphs show the small-world effect, including social networks, wikis such as Wikipedia, gene networks, and even the underlying architecture of the Internet. It is the inspiration for many network-on-chip architectures in contempo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Network For Social Network Analysis
The International Network for Social Network Analysis (INSNA) is a professional academic association of researchers and practitioners of social network analysis. Members have interests in social networks as a new theoretical paradigm, in methodological developments, and in a variety of applications of different types of social networks approaches, social network software, and social networking. History INSNA was founded in 1977 by Barry Wellman, a sociologist. A key function of the organization was to provide a sense of identity for a set of researchers who were widely dispersed geographically and across scientific disciplines. Wellman served as "coordinator" of INSNA until 1988, when he passed the baton to Al Wolfe, an anthropologist at the University of South Florida. Wolfe in turn passed the leadership to Steve Borgatti, who served from 1993 to 1999. Borgatti incorporated INSNA as a legal entity, creating bylaws and establishing the positions of President, Vice-President and Tre ...

Collective Network
A collective network is a set of social groups linked, directly or indirectly, by some common bond. According to this approach of the social sciences to study social relationships, social phenomena are investigated through the properties of relations among groups, which also influence the internal relations among the individuals of each group within the set. Overview A collective network may be defined a set of social groups linked, directly or indirectly, by some common bond, shared group status, similar or shared group functions, or geographic or cultural connection; the intergroup links also reinforce the intragroup links, hence the group identity. In informal types of associations, such as the mobilisation of social movements, a collective network may be a set of groups whose individuals, though not necessarily knowing each other or sharing anything outside the organising criteria of the network, are psychologically bound to the network itself and are willing to maintain it indef ...

Social Network Analysis
Social network analysis (SNA) is the process of investigating social structures through the use of networks and graph theory. It characterizes networked structures in terms of ''nodes'' (individual actors, people, or things within the network) and the ''ties'', ''edges'', or ''links'' (relationships or interactions) that connect them. Examples of social structures commonly visualized through social network analysis include social media networks, memes spread, information circulation, friendship and acquaintance networks, business networks, knowledge networks, difficult working relationships, social networks, collaboration graphs, kinship, disease transmission, and sexual relationships. These networks are often visualized through ''sociograms'' in which nodes are represented as points and ties are represented as lines. These visualizations provide a means of qualitatively assessing networks by varying the visual representation of their nodes and edges to reflect attributes of in ...

Social Network
A social network is a social structure made up of a set of social actors (such as individuals or organizations), sets of dyadic ties, and other social interactions between actors. The social network perspective provides a set of methods for analyzing the structure of whole social entities as well as a variety of theories explaining the patterns observed in these structures. The study of these structures uses social network analysis to identify local and global patterns, locate influential entities, and examine network dynamics. Social networks and the analysis of them is an inherently interdisciplinary academic field which emerged from social psychology, sociology, statistics, and graph theory. Georg Simmel authored early structural theories in sociology emphasizing the dynamics of triads and "web of group affiliations". Jacob Moreno is credited with developing the first sociograms in the 1930s to study interpersonal relationships. These approaches were mathematically formalize ...

Self-monitoring
Self-monitoring, a concept introduced in the 1970s by Mark Snyder (psychologist), Mark Snyder, describes the extent to which people monitor their self-presentations, expressive behavior, and nonverbal affective displays. Snyder held that human beings generally differ in substantial ways in their abilities and desires to engage in expressive controls (see Dramaturgy (sociology), dramaturgy).Snyder, 1974 Self-monitoring is defined as a personality trait that refers to an ability to regulate behavior to accommodate social situations. People concerned with their expressive self-presentation (see impression management) tend to closely monitor their audience in order to ensure appropriate or desired public appearances. Self-monitors try to understand how individuals and groups will perceive their actions. Some personality types commonly act spontaneously (low self-monitors) and others are more apt to purposely control and consciously adjust their behavior (high self-monitors). Recent stud ...

Need For Affiliation
The need for affiliation (N-Affil) is a term that was popularized by David McClelland and describes a person's need to feel a sense of involvement and "belonging" within a social group; McClelland's thinking was strongly influenced by the pioneering work of Henry Murray who first identified underlying psychological human needs and motivational processes (1938). It was Murray who set out a classification of needs, including achievement, power and affiliation—and placed these in the context of an integrated motivational model. People with a high need for affiliation require warm interpersonal relationships and approval from those with whom they have regular contact. Having a strong bond with others make a person feel as if they are a part of something important that creates a powerful impact. People who place high emphasis on affiliation tend to be supportive team members, but may be less effective in leadership positions. A person who takes part in a group, whether it be a movement ...

Need For Achievement
Need for achievement (N-Ach) is an individual's desire for significant accomplishment, mastering of skills, control, or high standards. The term was first used by Henry Murray and associated with a range of actions. These include: "intense, prolonged and repeated efforts to accomplish something difficult. To work with singleness of purpose towards a high and distant goal. To have the determination to win". The concept of N-Ach was subsequently popularized by the psychologist David McClelland.D. C. McClelland. (1961). The Achieving Society. Free Press, New York __TOC__ Overview This personality trait is characterized by an enduring and consistent concern with setting and meeting high standards of achievement. This need is influenced by internal drive for action (intrinsic motivation), and the pressure exerted by the expectations of others (extrinsic motivation). Measured with the thematic apperception test (TAT), need for achievement motivates an individual to succeed in competition ...

Heuristics
A heuristic (; ), or heuristic technique, is any approach to problem solving or self-discovery that employs a practical method that is not guaranteed to be optimal, perfect, or rational, but is nevertheless sufficient for reaching an immediate, short-term goal or approximation. Where finding an optimal solution is impossible or impractical, heuristic methods can be used to speed up the process of finding a satisfactory solution. Heuristics can be mental shortcuts that ease the cognitive load of making a decision. Examples that employ heuristics include using trial and error, a rule of thumb or an ansatz, educated guess. Heuristics are the strategies derived from previous experiences with similar problems. These strategies depend on using readily accessible, though loosely applicable, information to control problem solving in human beings, machines and abstract issues. When an individual applies a heuristic in practice, it generally performs as expected. However it can alternati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Priming (psychology)
Priming is a phenomenon whereby exposure to one stimulus influences a response to a subsequent stimulus, without conscious guidance or intention. The priming effect refers to the positive or negative effect of a rapidly presented stimulus (priming stimulus) on the processing of a second stimulus (target stimulus) that appears shortly after. Generally speaking, the generation of priming effect depends on the existence of some positive or negative relationship between priming and target stimuli. For example, the word ''nurse'' is recognized more quickly following the word ''doctor'' than following the word ''bread''. Priming can be perceptual, associative, repetitive, positive, negative, affective, semantic, or conceptual. Priming effects involve word recognition, semantic processing, attention, unconscious processing, and many other issues, and are related to differences in various writing systems. Research, however, has yet to firmly establish the duration of priming effects, yet th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
