Edwin Hutchins (born 1948) is a professor and former department head of cognitive science at the University of California, San Diego . Hutchins is one of the main developers of distributed cognition .
41-521: Hutchins was a student of the cognitive anthropologist Roy D'Andrade and has been a strong advocate of the use of anthropological methods in cognitive science . He is considered the father of modern cognitive ethnography . His early work involved studies of logic in legal discourse among people of the Trobriand Islands , Papua New Guinea . For a time he worked in the Navy doing research on how crews of

Also, note that factor scores are usually provided as standardized variables (mean of zero), but may be transformed back to your original data collection units. When used as a method for analysis, the cultural consensus theory allows the following: the determination whether the observed variability in knowledge
123-409: A best estimate of the “true” answers nor do they estimate competence of the raters. Cultural consensus theory can estimate competence from the agreement between subjects and then, answers are estimated by “weighting” individual responses by competence prior to aggregation. A very important feature in the aggregation of responses is that the combined responses of individuals will be more accurate than
164-420: A factor analysis procedure, requesting the minimum-residual (principal axis factoring) algorithm method that solves for the missing diagonal without rotation. When factor analysis is used for consensus applications, ~~the data must be transposed, so that questions are the unit of analysis (the rows in a data matrix) and people are the variables~~ (the columns in the data matrix). An advantage of cultural consensus
205-432: A framework for estimating cultural beliefs. A formal model is based on the decision-making process model of how questions are answered (with parameters for competence, response bias, and guessing). The model proceeds from axioms and uses mathematical proofs to arrive at estimates of competence and answers to a series of questions. The informal model is a set of statistical procedures that provides similar information. Given
246-605: A greater insight into cognitive motivations, hence the field’s similarity to linguistic relativism . To advocates, the mind is a cultural facet (as is kinship to the pioneering cultural anthropologist) that generates language, which provides insight into human cognition. Other advocates for cognitive anthropology’s categorization with cognitive science have pointed out that cognitive psychology fails to encompass several fields that cognitive anthropology does, hence its pivotal role in cognitive science. Professor of Psychology at University of Connecticut , James S. Boster, points out in
287-414: A series of related questions, the agreement between people's reported answers is used to estimate their cultural competence. Cultural competence is how much an individual knows or shares group beliefs. Since the extraction of individual competencies depends upon having a single factor solution, the ratio of the first and second eigenvalues (> 3:1) serves as a goodness-of-fit indicator that a single factor
328-612: A ship can function as a distributed machine, offloading the cognitive burden of ship navigation onto each member of the crew. He was a recipient of the prestigious MacArthur "Genius Grant" . In 1995, Hutchins published Cognition in the Wild , a detailed study of distributed cognitive processes in a navy ship (an Iwo Jima -class amphibious assault ship ); like other works related to distributed cognition, it criticizes disembodied views of cognition and proposes an alternative which looks at cognitive systems that may be composed of multiple agents and
369-401: A single response pattern. Individual competence values are used to weight the responses and estimate the culturally correct answers. In the formal model, a confidence level ( Bayesian adjusted probabilities ) is obtained for each answer from the pattern of responses and the individual competence scores. In the informal model, responses are also weighted, using a linear model . When factoring
410-458: A single set of shared answers and then estimating the answers and individual cultural competence in answering the questions. The theory is designed for the estimation of “culturally correct” answers to questions that are unknown a priori to the researcher, as well as item response effects (e.g., knowledge level, response biases, item difficulty). Cultural consensus models do not create consensus or explain why consensus exists; they simply facilitate
451-755: A subset of the psychological sciences, focus on common narratives throughout different cultures rather than on the individual mind, and difficulty of getting published. "They strive for insights that explain something about the human mind in general and therefore consider cross‐cultural comparisons as just one means to test assumptions on universals." Critics have also disputed the scientific nature of cognitive anthropology in general and argued that it studies content of thought rather than process, which cognitive science centers on. Resistance from more established subfields of cultural anthropology has historically restricted resources and tenure for cognitive anthropologists. Consensus analysis Cultural consensus theory

Cognitive anthropology Cognitive anthropology is an approach within cultural anthropology and biological anthropology in which scholars seek to explain patterns of shared knowledge, cultural innovation , and transmission over time and space using the methods and theories of the cognitive sciences (especially experimental psychology and cognitive psychology ) often through close collaboration with historians, ethnographers , archaeologists, linguists, musicologists , and other specialists engaged in
533-421: Is a common understanding of what the world and society are all about. Since the amount of information in a culture is too large for any one individual to master, individuals know different subsets of the cultural knowledge and vary in their cultural competence. Cultural beliefs are beliefs held by a majority of culture members. Given a set of questions, on the same topic, shared cultural beliefs or norms regarding
574-490: Is an approach to information pooling (aggregation, data fusion) which supports a framework for the measurement and evaluation of beliefs as cultural ; shared to some extent by a group of individuals. Cultural consensus models guide the aggregation of responses from individuals to estimate (1) the culturally appropriate answers to a series of related questions (when the answers are unknown) and (2) individual competence (cultural competence) in answering those questions. The theory
615-429: Is applicable when there is sufficient agreement across people to assume that a single set of answers exists. The agreement between pairs of individuals is used to estimate individual cultural competence. Answers are estimated by weighting responses of individuals by their competence and then combining responses. Cultural consensus theory assumes that cultural beliefs are learned and shared across people and that there
656-446: Is cultural; the measurement of cultural competence that each individual possesses; and, the determination of culturally correct knowledge. Cultural Consensus analyses may be performed with software applications. The formal consensus model is currently only available in the software packages ANTHROPAC or UCINET . Analysis procedures for the informal model are available in most statistical packages. The informal model can be run within
697-491: Is linked to psychology because studying the way social groups reason and categorize raises questions about the basic nature of cognitive processes. Advocate and presidential researcher Giovanni Bennardo put forth three categories of data in 2013 that warrant this grouping. Cognitive anthropologists gather ethnographic, linguistic, and experimental data, which is then analyzed quantitatively. For example, medical rituals provide more direct data that informs linguistic analysis and
738-406: Is preferred, but principal axis factoring can be used as well.) To determine whether the solution meets cultural consensus criteria, that only a single factor is present, a goodness of fit rule is used. If the ratio of the first to second eigenvalues is large with subsequently small values and all first factor loadings are positive, then it is assumed that the data contain only a single factor or
779-645: Is seen as too quantitative and scientific for the prevailing post‐modern aesthetic, while at the same time seen as too ethnographic and natural historical for the tastes of CP." Some cognitive scientists have devalued anthropology's influence in the cognitive sciences, which was extensively discussed by Sieghard Beller, Andrea Bender, and Douglas Medin in the Journal of the Cognitive Science Society. In their widely cited journal article, they attribute this rejection to cognitive anthropology's lack of credibility as
820-442: Is separated in two categories, thought in society/culture and language. Thought is concerned with the procedure and outcome of thoughts. The thinking process in cognitive anthropology puts the importance of culture at the center of examining thoughts. Cognitive anthropologists believe that cultural meanings arise when people learn, create, interpret and apply these collective representations. Reapplication and representations reinforce
861-414: Is the availability of necessary sample size information and that necessary sample sizes do not need to be very large. Sample size determination in a consensus analysis is similar to other types of analyses; namely, that when variability is low, power is high and small samples will suffice. Here, variability is the agreement (competence) among subjects. For the formal model, sample size can be estimated from

#1732858958865902-506: The Journal of the Cognitive Science Society that while cognitive psychology studies a human’s thought process, cognitive anthropology studies what exactly different humans ponder—what they sense and perceive of their own culture and surroundings in different settings. There has been longtime conflict between cognitive scientists and cognitive anthropologists on the intersection of their respective fields. The grouping has received much backlash in
943-479: The Spearman–Brown prophecy formula (applied to people instead of items). For a relatively low level of agreement (an average correlation of .25 between people, comparable to an average competence of .50) and a high degree of desired validity (.95 correlation between the estimated answers and the true answers), a study would require a minimum sample size of 30 subjects. In summary, cultural consensus theory offers
984-463: The 1950s spearheading the effort to approach cognition in cultural contexts, rather than as an effort to identify or assume cognitive universals. Cognitive anthropology became a current paradigm of anthropology under the new ethnography or ethnoscience paradigm that emerged in American anthropology toward the end of the 1950s. Cognitive anthropology studies a range of domains including folk taxonomies,
1025-454: The accuracy of reported information. One specific method of the formal version used in the analysis of data is the mathematical model, which is a set of logical axioms as well as derived propositions and assumptions that explain how empirical variables fit in the model's parameters. The informal model, on the other hand, uses reliability analysis. Cultural competence is estimated from the similarity in responses between pairs of subjects since
1066-404: The agreement between a pair of respondents is a function of their individual competencies. In the formal model, the similarity is the probability that matched responses occur (match method. or the probability of particular response combinations occur (covariance method ). Simple match or covariance measures are then corrected for guessing and the proportion of positive responses, respectively. In
1107-452: The answers can be estimated by aggregating the responses across a sample of culture members. When an agreement is close to absolute, estimating answers is straightforward. The problem addressed by cultural consensus theory is how to estimate beliefs when there is some degree of heterogeneity present in responses. In general, cultural consensus theory provides a framework for determining whether responses are sufficiently homogeneous to estimate
1148-537: The decision-making process for answering questions. This version is limited to categorical-type responses: multiple-choice type questions (including those with dichotomous true/false or yes/no responses) and responses to open-ended questions (with a single word or short phrase response for each question). This version of the model has a series of additional assumptions that must be met, i.e., no response bias. The formal model has direct parallels in signal detection theory and latent class analysis. An informal version of
1189-458: The description and interpretation of cultural forms. Cognitive anthropology is concerned with what people from different groups know and how that implicit knowledge, in the sense of what they think subconsciously, changes the way people perceive and relate to the world around them. Cognitive anthropology arose as part of efforts designed to understand the relationship between language and thought, with linguistic anthropologists of North America in
1230-463: The discovery and description of possible consensus. A high degree of agreement among raters must be present in responses to use consensus theory – only with high agreement does it make sense to aggregate responses to estimate beliefs of the group. Although there are statistical methods to evaluate whether agreement among raters is greater than chance ( Binomial test , Friedman test , or Kendall's coefficient of concordance ), these methods do not provide
1271-536: The experienced patterns through the process of implementing appropriateness and relevance, contain the elements for cognitive reorganization and creativity in behavior and understanding. In cognitive anthropology language is seen as an important source for analyzing thinking processes. Cognitive anthropology analyzes cultural views with lexicons as the primary source of data that researches search for definite beliefs, implicit understandings and category systems. Cognitive anthropology uses quantitative measures as well as

1312-400: The informal model, similarity is calculated with a Pearson correlation coefficient . A matrix of agreement coefficients between all pairs of subjects is then factored with a minimum residual factoring method ( principal axis factoring without rotation ) to solve for the unknown competence values on the main diagonal. (For the informal model, the maximum likelihood factor analysis algorithm
1353-451: The interaction of language and thought, and cultural models. From a linguistics stand-point, cognitive anthropology uses language as the doorway to study cognition. Its general goal is to break language down to find commonalities in different cultures and the ways people perceive the world. Linguistic study of cognitive anthropology may be broken down into three subfields: semantics , syntactics , and pragmatics . Cognitive anthropology

Similarly, sample size can be estimated with reliability theory and

The informal model parallels a factor analysis on people (without rotation) and thus has similarities to Q factor analysis (as in Q Methodology) . The informal version of the model can accommodate interval estimates and ranked response data. Both approaches provide estimates of the culturally correct answers and estimates of individual differences in
1558-453: The number of subjects and the average Pearson correlation coefficient between all pairs of subjects (across questions). To use cultural consensus theory, at least three assumptions must be met: Cultural consensus theory encompasses formal and informal models. Practically speaking, these models are often used to estimate cultural beliefs, including the degree to which individuals report such beliefs. The formal cultural consensus model models
1599-414: The reflexive nature of their study. Instead of analyzing facets of culture as they appear to the anthropologist, they place special emphasis on emic viewpoints of culture to understand what motivates different populations, eventually coming to an understanding of universal cognition. These goals form the basis of the argument merging cognitive anthropology and cognitive science . Cognitive anthropology
1640-428: The responses of each individual included in the aggregation. Reliability theory in psychology (specifically, the reliability coefficient and the Spearman–Brown prediction formula ) provides a mathematical estimate of the accuracy or validity of aggregated responses from the number of units being combined and the level of agreement among the units. In this case, the accuracy of aggregated responses can be calculated from
1681-778: The traditional ethnographic methods of cultural anthropology in order to study culture. Because of the field's interest in determining shared knowledge, consensus analysis has been used as its most widely used statistical measure. One of the techniques used is Cultural Network Analysis , the drawing of networks of interrelated ideas that are widely shared among members of a population. Recently there has been some interchange between cognitive anthropologists and those working in artificial intelligence. Cognitive anthropology intersects with several other fields within its parent cultural anthropology sphere. Whereas cultural anthropologists had always sought to identify and organize certain salient facets of culture, cognitive anthropologists appreciate
