Laboratory of Comparative Human Cognition (LCHC) [1] is a social science laboratory located at the University of California, San Diego (UCSD) since 1978. Scholars at LCHC pursue research focused on understanding the complex relationship between cognition and culture in individual and social development. Such research requires collaboration among scholars from a variety of research disciplines, including cognitive science, education, linguistics, psychology, anthropology, and sociology. LCHC also functions as a research and training institution, arranging for pre-doctoral, doctoral, and post-doctoral training, as well as research exchanges with scholars throughout the world. In addition, LCHC sponsors a journal, Mind, Culture and Activity: An International Journal (MCA), [2] and an open internet discussion group, XMCA. [3]
The LCHC is rooted in several research traditions and interests, beginning with cross-cultural research in Africa and Mexico on the developmental impact of indigenous practices, literacy, and schooling. The methodological approach of this research was a blend of experimental psychology and cognitive ethnography that highlighted the roles of cultural contexts and the need to carefully study local practices and local people's interpretations of those practices. As this research developed, it drew inspiration from Soviet psychology, [4] cultural psychology, Black psychology, cultural anthropology, distributed cognition, actor-network theory, and American pragmatism. LCHC has also been strongly influenced by ideas from developmental psychology and takes a strong multidisciplinary, “theory and practice” approach to the social sciences and humanities. [5]
Of the influences mentioned above, Soviet psychology, cultural anthropology, and American pragmatism have been particularly important to the intellectual formation of members of the LCHC. From Soviet psychology—specifically the work of cultural-historical psychologist Lev Vygotsky (1896–1934) and Vygotsky-inspired cultural-historical activity theory (CHAT), [6] LCHC researchers inherited an interest in cultural mediation—the idea that humans use cultural artifacts to control both their environments and their own actions. This interest in mediation was coupled with a concern for the activities that cultural artifacts mediate. From this combined approach, LCHC researchers seek to make visible for analysis those processes "that realize a person’s actual life in the objective world by which he is surrounded, his social being in all the richness and variety of its forms" (A.N. Leont’ev, 1977 [7] ). From cultural anthropology (e.g., Gregory Bateson, Roy D'Andrade, Clifford Geertz) and American pragmatism (e.g., John Dewey, George Mead, Charles Peirce) LCHC adopted both methods for the analysis of behavior in situ (ethnography, the comparative method, modes of discourse analysis) and theoretical guidance for thinking about the co-constitution of persons and their environments, and the histories of the cultural practices through which they lead their lives.
Taken together, these domains of social science theory and methodology have informed the diverse research projects of the members of the LCHC. By integrating these approaches, LCHC researchers combine cultural-historical psychologists’ insistence on historical/developmental analysis [8] (influenced by Marxism) with anthropologist's/pragmatist's emphasis on the analysis of concrete activity systems and the diversity of such systems within and between societies.
The LCHC emerged during the Civil Rights Movement, a time when issues regarding education and employment for minorities were being sharply debated. On a world scale, groups such as UNESCO were concerned with how to improve education throughout the developing world. This historical context motivated foundations to give grants to LCHC to conduct research on apparent cultural variations in cognitive development and their significance for maximizing success in schooling. [9]
LCHC was originally based at Rockefeller University in New York City from 1971 to 1978 and has been based at the UC San Diego (UCSD) from 1978 to the present. When the LCHC relocated from New York to California, it changed both its university and departmental setting, with its new base of operations now in the Department of Communication. [10] This institutional relocation permitted the LCHC to: 1) expand its research concerns to include the use of new communication technologies in various settings; 2) forge community partnerships in the racially, economically, and politically diverse border-city of San Diego; and 3) situate LCHC research within the discipline of communication studies, for which mediation is a central, constitutive, concept. [11]
The LCHC has participated in key cross-cultural studies, such as research projects with the Kpelle people and the Vai people (both of Liberia), and rural residents in Yucatan, Mexico. These studies were instrumental in formulating a critique of contemporaneous methods of cross-cultural and developmental psychology. LCHC researchers argued that studies of human cognitive activity must be grounded in the actual materials and processes of people's daily lives (ecological validity). Using this approach, they demonstrated that years of schooling strongly influence performance on many common cognitive tasks, but that such influences do not support the conclusion of a general cognitive impact of schooling on cognitive development. [12] This work called into question the use of cognitive tasks to measure school achievement by showing that schooled children scored better on psychological tests while performing far below expectations on their schoolwork.[ citation needed ] This finding refocused research attention to the link between activities that children engaged in outside of formal schooling and their performance in the classroom.[ citation needed ] The interplay between informal and formal educational activities continues to concern LCHC researchers today.
LCHC has been noted for conducting comparative developmental studies in a number of domains of social practice in the United States, including: comparative studies of language and cognitive development [13] among children of different ethnicities and social classes or with differing forms of apparent learning disability; building model activity systems[ citation needed ] to promote learning and development, such as Playworlds [14] and the Fifth Dimension; [15] and studies of development in work settings. [16]
Current active topics of research at LCHC include: adult-child fantasy play worlds as media for inter-generational development; [17] intervention research using methods of design research, [18] formative experiments,[ citation needed ] and studies of the micro-genesis of developmental change mediated by new technologies.
The LCHC's physical location on the UCSD campus is rarely the site of data collection because of LCHC's methodological imperative: to observe cognition and other psychological phenomena in everyday activities, then to use the structure of that activity as a template for creating experiments, conceived of as model activity systems.
LCHC research programs strive to meet the practical need for developing democratic collaborations. On the one hand, this need requires local community members to participate in the activities of the laboratory, creating partnerships between academics and non-academics referred to as UCLinks. [19] On the other hand, within the academic community, democratic collaboration requires faculty, graduate, and undergraduate students share responsibility for the implementation of research, creating a multi-generational system of joint activities.
Internationalism in research efforts has been a hallmark of the LCHC since its inception. Of special note in this regard is the VelHam Project, [20] which was an ambitious attempt to link Soviet and U.S. educationalists and children engaged in common after-school activities through satellite feeds during the 1980s, and XMCA, a network of scholars seeking to develop the general set of ideas which underpin LCHC's reason for being.
The LCHC has a tradition of using modern communication and computer technologies in its research work. This tradition stemmed from a focus on the cultural tools (mediational means) that are central to all culturally organized human activity, and from efforts to extend the scholarly community that pursued issues of mutual concern to members of the LCHC. The role of digital technologies in settings for education, work, and play has and continues to influence the LCHC's research and intervention agenda, as evidenced by the Fifth Dimension [21] and UCLinks [22] projects. LCHC researchers also use digital audio- and video-recording technology for data collection, recording real-time interaction that can be analyzed later at multiple levels.
The LCHC has been directly and indirectly involved with many kinds of publication projects. It created LCHC Newsletter [23] (1976 to 1993) to initiate an international discussion about culture in development, followed by the refereed academic journal MCA [24] (1994 to present). It began sponsoring a listserv in the early 1980s (formerly XLCHC, now called XMCA [25] ) where scholars from all over the world discuss the issue of culture and development in a broad, interdisciplinary manner, communicating about topics such as cultural psychology, Vygotsky, cultural-historical activity theory, [26] and more.
Owing to its basic philosophy of research, the LCHC is notable for collaboration with a wide range of researchers in different disciplines and parts of the world. Of special note is the close collaboration between the LCHC and the Center for Research on Activity, Development and Learning (CRADLE) [27] (was Center for Activity Theory and Developmental Work Research), and its long-term support of ISCAR (International Society for Cultural and Activity Research). [28]
Hundreds of researchers have been associated with LCHC over the years and remain associated through its networking system.
Educational psychology is the branch of psychology concerned with the scientific study of human learning. The study of learning processes, from both cognitive and behavioral perspectives, allows researchers to understand individual differences in intelligence, cognitive development, affect, motivation, self-regulation, and self-concept, as well as their role in learning. The field of educational psychology relies heavily on quantitative methods, including testing and measurement, to enhance educational activities related to instructional design, classroom management, and assessment, which serve to facilitate learning processes in various educational settings across the lifespan.
Lev Semyonovich Vygotsky was a Soviet psychologist, best known for his work on psychological development in children and creating the framework known as cultural-historical activity theory.
Alexander Romanovich Luria was a Soviet neuropsychologist, often credited as a father of modern neuropsychology. He developed an extensive and original battery of neuropsychological tests during his clinical work with brain-injured victims of World War II, which are still used in various forms. He made an in-depth analysis of the functioning of various brain regions and integrative processes of the brain in general. Luria's magnum opus, Higher Cortical Functions in Man (1962), is a much-used psychological textbook which has been translated into many languages and which he supplemented with The Working Brain in 1973.
Intercultural relations, sometimes called intercultural studies, is a relatively new formal field of social science studies. It is a practical, multi-field discipline designed to train its students to understand, communicate, and accomplish specific goals outside their own cultures. Intercultural relations involves, at a fundamental level, learning how to see oneself and the world through the eyes of another. It seeks to prepare students for interaction with cultures both similar to their own or very different from their own. Some aspects of intercultural relations also include, their power and cultural identity with how the relationship should be upheld with other foreign countries.
Aleksei Nikolayevich Leontiev, was a Soviet developmental psychologist and philosopher and a founder of activity theory.
Activity theory is an umbrella term for a line of eclectic social-sciences theories and research with its roots in the Soviet psychological activity theory pioneered by Sergei Rubinstein in the 1930s. It was later advocated for and popularized by Alexei Leont'ev. Some of the traces of the theory in its inception can also be found in a few works of Lev Vygotsky. These scholars sought to understand human activities as systemic and socially situated phenomena and to go beyond paradigms of reflexology and classical conditioning, psychoanalysis and behaviorism. It became one of the major psychological approaches in the former USSR, being widely used in both theoretical and applied psychology, and in education, professional training, ergonomics, social psychology and work psychology.
The psychology of learning refers to theories and research on how individuals learn. There are many theories of learning. Some take on a more behaviorist approach which focuses on inputs and reinforcements. Other approaches, such as theories related to neuroscience and social cognition, focus more on how the brain's organization and structure influence learning. Some psychological approaches, such as social constructivism, focus more on one's interaction with the environment and with others. Other theories, such as those related to motivation, like the growth mindset, focus more on individuals' perceptions of ability.
Cognitive development is a field of study in neuroscience and psychology focusing on a child's development in terms of information processing, conceptual resources, perceptual skill, language learning, and other aspects of the developed adult brain and cognitive psychology. Qualitative differences between how a child processes their waking experience and how an adult processes their waking experience are acknowledged. Cognitive development is defined as the emergence of the ability to consciously cognize, understand, and articulate their understanding in adult terms. Cognitive development is how a person perceives, thinks, and gains understanding of their world through the relations of genetic and learning factors. There are four stages to cognitive information development. They are, reasoning, intelligence, language, and memory. These stages start when the baby is about 18 months old, they play with toys, listen to their parents speak, they watch tv, anything that catches their attention helps build their cognitive development.
The zone of proximal development (ZPD) is a concept in educational psychology. It represents the space between what a learner is capable of doing unsupported and what the learner cannot do even with support. It is the range where the learner is able to perform, but only with support from a teacher or a peer with more knowledge or expertise. The concept was introduced, but not fully developed, by psychologist Lev Vygotsky (1896–1934) during the last three years of his life. Vygotsky argued that a child gets involved in a dialogue with the "more knowledgeable other" such as a peer or an adult and gradually, through social interaction and sense-making, develops the ability to solve problems independently and do certain tasks without help. Following Vygotsky, some educators believe that the role of education is to give children experiences that are within their zones of proximal development, thereby encouraging and advancing their individual learning such as skills and strategies.
Group cognition is a social, largely linguistic phenomenon whereby a group of people produce a sequence of utterances that performs a cognitive act. That is, if a similar sequence was uttered or thought by an individual it would be considered an act of cognition or thinking. The group can be a small group, such as 3–5 people talking together or working together online. The group can also be a larger collective, such as a classroom of students or a global community contributing asynchronously to an extended discourse on a problem or topic or to a knowledge repository like Wikipedia. The theory of group cognition is a postcognitivism philosophy, which considers a larger unit of analysis than an individual mind as a producer of cognitive activities such as creative problem solving.
The Kharkov school of psychology is a tradition of developmental psychological research conducted in the paradigm of Lev Vygotsky's "sociocultural theory of mind" and Leontiev's psychological activity theory.
Cultural-historical psychology is a branch of psychological theory and practice associated with Lev Vygotsky and Alexander Luria and their Circle, who initiated it in the mid-1920s–1930s. The phrase "cultural-historical psychology" never occurs in the writings of Vygotsky, and was subsequently ascribed to him by his critics and followers alike, yet it is under this title that this intellectual movement is now widely known. The main goal of Vygotsky-Luria project was the establishment of a "new psychology" that would account for the inseparable unity of mind, brain and culture in their development in concrete socio-historical settings and throughout the history of humankind as socio-biological species. In its most radical forms, the theory that Vygotsky and Luria were attempting to build was expressed in terms of a "science of Superman", and was closely linked with the pronouncement for the need in a new psychological theory of consciousness and its relationship to the development of higher psychological functions. All this theoretical and experimental empirical work was attempted by the members of the Vygotsky Circle.
Private speech is speech spoken to oneself for communication, self-guidance, and self-regulation of behaviour. It is between the ages of two and seven that children can be observed engaging in private speech. Although it is audible, it is neither intended for nor directed at others. Private speech was first studied by Lev Vygotsky (1934/1986) and Jean Piaget (1959); in the past 30 years private speech has received renewed attention from researchers. Researchers have noted a positive correlation between children's use of private speech and their task performance and achievement, a fact also noted previously by Vygotsky. It is when children begin school that their use of private speech decreases and "goes underground".
Cultural mediation describes a profession that studies the cultural differences between people, using the data in problem solving. It is one of the fundamental mechanisms of distinctly human development according to cultural–historical psychological theory introduced by Lev Vygotsky and developed in the work of his numerous followers worldwide.
Infant cognitive development is the first stage of human cognitive development, in the youngest children. The academic field of infant cognitive development studies of how psychological processes involved in thinking and knowing develop in young children. Information is acquired in a number of ways including through sight, sound, touch, taste, smell and language, all of which require processing by our cognitive system.
Katherine Nelson was an American developmental psychologist, and professor.
The Mental and Social Life of Babies is a 1982 book by Kenneth Kaye. Integrating a contemporary burgeoning field of research on infant cognitive and social development in the first two years of life with his own laboratory's studies at the University of Chicago, Kaye offered an "apprenticeship" theory. Seen as an empirical turning point in the investigation of processes in early human development, the book's reviews welcomed its reliance on close process studies of a large sample of infants and mothers (50) recorded longitudinally. It was republished in England, Japan, Spain, Italy, and Argentina.
In the framework of the Cultural-Historical Activity Theory (CHAT) the leading activity is the activity, or cooperative human action, which plays the most essential role in child development during a given developmental period. Although many activities may play a role in a child's development at any given time, the leading activity is theorized to be the type of social interaction that is most beneficial in terms of producing major developmental accomplishments, and preparing the child for the next period of development. Through engaging in leading activities, a child develops a wide range of capabilities, including emotional connection with others, motivation to engage in more complex social activities, the creation of new cognitive abilities, and the restructuring of old ones.
Cultural-historical activity theory (CHAT) is a theoretical framework which helps to understand and analyse the relationship between the human mind and activity. It traces its origins to the founders of the cultural-historical school of Russian psychology L. S. Vygotsky and Aleksei N. Leontiev. Vygotsky's important insight into the dynamics of consciousness was that it is essentially subjective and shaped by the history of each individual's social and cultural experience. Especially since the 1990s, CHAT has attracted a growing interest among academics worldwide. Elsewhere CHAT has been defined as "a cross-disciplinary framework for studying how humans purposefully transform natural and social reality, including themselves, as an ongoing culturally and historically situated, materially and socially mediated process". Core ideas are: 1) humans act collectively, learn by doing, and communicate in and via their actions; 2) humans make, employ, and adapt tools of all kinds to learn and communicate; and 3) community is central to the process of making and interpreting meaning – and thus to all forms of learning, communicating, and acting.
Vera (Veronka) John-Steiner was a Hungarian-American educational psychologist and activist. She was known for her work on creative collaboration, and her contributions to psycholinguistics, cultural-historical activity theory, cross-cultural education, bilingualism, psychology of women, and cognitive psychology. Her theoretical framework was heavily influenced by the work of Lev Vygotsky. In 2007, the American Educational Research Association honored her with its Lifetime Achievement Award.
