Domain-general learning

Last updated

Domain-general learning theories of development suggest that humans are born with mechanisms in the brain that exist to support and guide learning on a broad level, regardless of the type of information being learned. [1] [2] [3] Domain-general learning theories also recognize that although learning different types of new information may be processed in the same way and in the same areas of the brain, different domains also function interdependently. Because these generalized domains work together, skills developed from one learned activity may translate into benefits with skills not yet learned. [4] Another facet of domain-general learning theories is that knowledge within domains is cumulative, and builds under these domains over time to contribute to our greater knowledge structure. Psychologists whose theories align with domain-general framework include developmental psychologist Jean Piaget, who theorized that people develop a global knowledge structure which contains cohesive, whole knowledge internalized from experience, and psychologist Charles Spearman, whose work led to a theory on the existence of a single factor accounting for all general cognitive ability.

Domain-general learning theories are in direct opposition to domain-specific learning theories, also sometimes called theories of Modularity. Domain-specific learning theories posit that humans learn different types of information differently, and have distinctions within the brain for many of these domains. Domain-specific learning theorists also assert that these neural domains are independent, purposed solely for the acquisition of one skill (i.e. facial recognition or mathematics), and may not provide direct benefits in the learning of other, unrelated skills.

Piaget’s Theory of Cognitive Development

Jean Piaget

Developmental psychologist, Jean Piaget, theorized that one's cognitive ability, or intelligence – defined as the ability to adapt to all aspects of reality – evolves through a series of four qualitatively distinct stages (the sensorimotor, pre-operational, concrete operational and formal operational stages). [5] Piaget's theory describes three core cognitive processes that serve as mechanisms for transitioning from one stage to the next.

Piaget's core processes for developmental change:

However, these processes are not the only processes responsible for progressing through Piaget's developmental stages. Each stage is differentiated based upon the types of conceptual content that can be mastered within it. [6] Piaget's theory holds that transitioning from one stage of development to the next is not only a result of assimilation, accommodation, and equilibration, but also a result of developmental changes in domain-general mechanisms. As humans mature, various domain-general mechanisms become more sophisticated, and thus, according to Piaget, allow for growth in cognitive functioning. [6]

For example, Piaget's theory notes that the humans transition into the concrete operation stage of cognitive development when they acquire the ability to take perspective, and no longer have egocentric thinking (a characteristic of the pre-operational stage). [5] [6] This change can be viewed as the result of developmental changes in information processing capacity. [6] Information processing is a mechanism that is used across many different domains of cognitive functioning, and thus can be seen as a domain-general mechanism.

Psychometric Theories of Intelligence

Psychometric analysis of measurements of human cognitive abilities (intelligence) may suggest that there is a single underlying mechanism that impacts how humans learn. In the early 20th century, Charles Spearman noticed that children's scores on different measures of cognitive abilities were positively correlated. Spearman believed that these correlations could be attributed to a general mental ability or process that is utilized across all cognitive tasks. Spearman labeled this general mental ability as the g factor, and believed g could represent an individual's overall cognitive functioning. The presence of this g factor across different cognitive measures is well-established and uncontroversial in statistical research. It may be that this g factor highlights domain-general learning (cognitive mechanisms involved in all cognition), and that this general learning accounts for the positive correlations across seemingly different cognitive tasks. It is important to note, however, there currently is no consensus to what causes the positive correlations.

The broad abilities recognized by the model are fluid intelligence (Gf), crystallized intelligence (Gc), general memory and learning (Gy), broad visual perception (Gv), broad auditory perception (Gu), broad retrieval ability (Gr), broad cognitive speediness (Gs), and processing speed (Gt). Carroll regarded the broad abilities as different "flavors" of g. Carroll three stratum model of human Intelligence.png

Carroll regarded the broad abilities as different "flavors" of g.

Spearman's work was expanded upon by Raymond B. Cattell, who broke g into two broad abilities: fluid intelligence (Gf) and crystallized intelligence (Gc). Cattell's student, John Horn, added additional broad abilities to Cattell's model of intelligence. In 1993, John B. Carroll added more specificity to Cattell and Horn's Gf-Gc model by adding a third layer of human intelligence factors. Carroll named these factors “narrow abilities”. Narrow abilities are described as abilities that do not correlate with skills outside their domain, following more along the lines of domain-specific learning theories.

Despite breaking g into more specific areas, or domains of intelligence, Carroll maintained that a single general ability was essential to intelligence theories. This suggests that Carroll, to some extent, believed cognitive abilities were domain-general.

Skills That May Be Acquired via Domain-General Mechanisms

As discussed above, Piaget's theory of cognitive development posits that periods of major developmental change come about due to maturation of domain-general cognitive mechanisms. However, although Piaget's theory of cognitive development can be credited with establishing the field of cognitive development, some aspects of his theory have not withstood the test of time.

Despite this, researchers that call themselves "neo-Piagetians" have often focused on the role domain-general cognitive processes in constraining cognitive development. [6] It had been found that many skills humans acquire require domain-general mechanisms rather than highly specialized cognitive mechanisms for development. Namely, memory, executive functioning, and language development.

Memory

One theory of memory development suggests that basic (domain-general) memory processes become more superior through maturation. [5] In this theory, basic memory processes are frequently used, rapidly executed memory activities. These activities include: association, generalization, recognition, and recall. The basic processes theory of memory development states that these memory processes underlie all cognition, as it holds that all more complex cognitive activities are built by combining these basic processes in different ways. [5] Thus, these memory basic processes can be seen as domain-general processes that can be applied across various domains.

Domain general processes in memory development:

In addition to these general processes, working Memory in particular has been extensively studied as it relates and functions as a domain-general mechanism to constraints on cognitive development. [7] For example, researchers believe that with maturation, one is able to hold more complex structures in their working memory, which results in an increase of possible computations that underlie inference and learning. [7] Thus, working memory can be viewed as a domain-general mechanism that aids development across many different domains.

Executive Functions

Researchers have expanded the search for domain-general mechanisms that underlie cognitive development beyond working memory. The advancement in cognitive neuroscience technology is credited as making this expansion possible. [7] Within the last decade, researchers have begun to focus on a group of cognitive mechanisms, collectively named Executive Functions. Mechanisms commonly labeled executive functions include: working memory, inhibition, set shifting, as well as higher-order mechanisms that involve combinations of the prior (planning, problem-solving, reasoning). [7]

Piagetian tasks – tasks that measure behaviors that relate to cognitive abilities associated with Piaget's developmental stages – have been used in studies of cognitive neuroscience to investigate whether executive functions relate to cognitive development. [6] Such studies revealed that the maturation of the prefrontal cortex (an area of the brain identified to underlie the development of executive functions such as working memory and inhibition) may relate to success on tasks that measure the Piagetian concept of object permanence. [6] [8] Thus, this research supports Piaget's notion that developmental changes in domain-general mechanisms promote cognitive development.

Language

The general cognitive processes perspective of language development emphasizes characteristics of the language learner as the source of development. The general cognitive processes perspective states that the broad cognitive processes are sufficient for a child to learn new words. These broad cognitive processes include: attending, perceiving, and remembering. [5] Important to this perspective is the idea that such cognitive processes are domain-general, and are applied to learning many different kinds of information in addition to benefiting word acquisition. [5] This perspective contrasts the grammatical cues perspective, which emphasizes characteristics of the language input as a source of development. Furthermore, the general cognitive processes perspective also contrasts the constraints perspective of language development, in which children are said to be able to learn many words quickly because of constraints that are specialized for language learning. [5]

Opposing Theories

The relationship between domain general learning and domain specific learning (also known as the modularity debate or modularity of mind) has been an ongoing debate for evolutionary psychologists. [7]

The modularity of mind or modularity debate states that the brain is constructed of neural structures (or modules) which have distinct functions. Jerry Fodor, an American philosopher and cognitive scientist, stated in his 1983 book that brain modules are specialized and may only operate on certain kinds of inputs. [9] According to Fodor, a module is defined as “functionally specialized cognitive systems”. These modules are said to be mostly independent, develop on different timetables, and are influenced by a variety of different experiences an individual may have. [10] Some argue that Piaget's domain general theory of learning undermines the influence of socio-cultural factors on an individual's development. More specifically, the theory does not explain the influence of parental nurture and social interactions on human development.

Domain-specific learning is a theory in developmental psychology that says the development of one set of skills is independent from the development of other types of skills. This theory suggests that training or practice in one area may not influence another. [11] Domain-specificity has been defined by Frankenhuis and Ploeger as that “a given cognitive mechanism accepts, or is specialized to operate on, only a specific class of information”. [12] Furthermore, domain-specific learning prescribes different learning activities for students in order to meet required learning outcomes. [13]

Modern cognitive psychologists suggest a more complex relationship between domain-generality and domain-specificity in the brain. Current research suggests these networks may exist together in the brain, and the extent to which they function in tandem may vary by task and skill-level. [4] [14]

Possible Applications

Workplaces

Technology advancements and changes in the labor market show the need for workers/employees to be adaptive. This may suggest that school curricular should incorporate activities focusing on developing the necessary skills for dynamic environments. People tend to use domain-general learning processes when initially learning how to perform and complete certain tasks, and less so once these tasks become extensively practiced. [15]

Early Childhood Education

Problem solving is considered to be an individual's ability to partake in cognitive processing in order to understand and solve problems where a solution may not be immediately apparent. Domain-specific problem solving skills may provide students with narrow knowledge and abilities. Because of this, school teachers, policy makers and curriculum developers may find it beneficial to incorporate domain general skills (such as time management, teamwork or leadership) in relation to problem solving into school curriculum. Domain general problem solving provides students with cross-curricular skills and strategies that can be transferred to multiple different situations/environments/domains. Examples of cross-curricular skills include, but are not limited to: information processing, self-regulation and decision making.

Language Development

Additionally, linguistic knowledge and language development are examples of domain-general skills[ citation needed ]. Infants can learn rules and identify patterns in stimuli which may imply learning and generalizable knowledge. This means parents of young children and early childhood educators may want to consider its application while supporting language development.

Human intelligence is the intellectual capability of humans, which is marked by complex cognitive feats and high levels of motivation and self-awareness. Using their intelligence, humans are able to learn, form concepts, understand, and apply logic and reason. Human intelligence is also thought to encompass our capacities to recognize patterns, plan, innovate, solve problems, make decisions, retain information, and use language to communicate.

In cognitive psychology, information processing is an approach to the goal of understanding human thinking that treats cognition as essentially computational in nature, with the mind being the software and the brain being the hardware. It arose in the 1940s and 1950s, after World War II. The information processing approach in psychology is closely allied to the computational theory of mind in philosophy; it is also related to cognitivism in psychology and functionalism in philosophy.

Modularity of mind is the notion that a mind may, at least in part, be composed of innate neural structures or mental modules which have distinct, established, and evolutionarily developed functions. However, different definitions of "module" have been proposed by different authors. According to Jerry Fodor, the author of Modularity of Mind, a system can be considered 'modular' if its functions are made of multiple dimensions or units to some degree. One example of modularity in the mind is binding. When one perceives an object, they take in not only the features of an object, but the integrated features that can operate in sync or independently that create a whole. Instead of just seeing red, round, plastic, and moving, the subject may experience a rolling red ball. Binding may suggest that the mind is modular because it takes multiple cognitive processes to perceive one thing.

The concepts of fluid intelligence (gf) and crystallized intelligence (gc) were introduced in 1963 by the psychologist Raymond Cattell. According to Cattell's psychometrically-based theory, general intelligence (g) is subdivided into gf and gc. Fluid intelligence is the ability to solve novel reasoning problems and is correlated with a number of important skills such as comprehension, problem-solving, and learning. Crystallized intelligence, on the other hand, involves the ability to deduce secondary relational abstractions by applying previously learned primary relational abstractions.

Piaget's Theory of Cognitive Development, or his "genetic epistemology," is a comprehensive theory about the nature and development of human intelligence. It was originated by the Swiss developmental psychologist Jean Piaget (1896–1980). The theory deals with the nature of knowledge itself and how humans gradually come to acquire, construct, and use it. Piaget's theory is mainly known as a developmental stage theory.

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 Cattell–Horn–Carroll theory, is a psychological theory on the structure of human cognitive abilities. Based on the work of three psychologists, Raymond B. Cattell, John L. Horn and John B. Carroll, the Cattell–Horn–Carroll theory is regarded as an important theory in the study of human intelligence. Based on a large body of research, spanning over 70 years, Carroll's Three Stratum theory was developed using the psychometric approach, the objective measurement of individual differences in abilities, and the application of factor analysis, a statistical technique which uncovers relationships between variables and the underlying structure of concepts such as 'intelligence'. The psychometric approach has consistently facilitated the development of reliable and valid measurement tools and continues to dominate the field of intelligence research.

Domain-specific learning theories of development hold that we have many independent, specialised knowledge structures (domains), rather than one cohesive knowledge structure. Thus, training in one domain may not impact another independent domain. Domain-general views instead suggest that children possess a "general developmental function" where skills are interrelated through a single cognitive system. Therefore, whereas domain-general theories would propose that acquisition of language and mathematical skill are developed by the same broad set of cognitive skills, domain-specific theories would propose that they are genetically, neurologically and computationally independent.

Neurodevelopmental framework for learning, like all frameworks, is an organizing structure through which learners and learning can be understood. Intelligence theories and neuropsychology inform many of them. The framework described below is a neurodevelopmental framework for learning. The neurodevelopmental framework was developed by the All Kinds of Minds Institute in collaboration with Dr. Mel Levine and the University of North Carolina's Clinical Center for the Study of Development and Learning. It is similar to other neuropsychological frameworks, including Alexander Luria's cultural-historical psychology and psychological activity theory, but also draws from disciplines such as speech-language pathology, occupational therapy, and physical therapy. It also shares components with other frameworks, some of which are listed below. However, it does not include a general intelligence factor, since the framework is used to describe learners in terms of profiles of strengths and weaknesses, as opposed to using labels, diagnoses, or broad ability levels. This framework was also developed to link with academic skills, such as reading and writing. Implications for education are discussed below as well as the connections to and compatibilities with several major educational policy issues.

Educational neuroscience is an emerging scientific field that brings together researchers in cognitive neuroscience, developmental cognitive neuroscience, educational psychology, educational technology, education theory and other related disciplines to explore the interactions between biological processes and education. Researchers in educational neuroscience investigate the neural mechanisms of reading, numerical cognition, attention and their attendant difficulties including dyslexia, dyscalculia and ADHD as they relate to education. Researchers in this area may link basic findings in cognitive neuroscience with educational technology to help in curriculum implementation for mathematics education and reading education. The aim of educational neuroscience is to generate basic and applied research that will provide a new transdisciplinary account of learning and teaching, which is capable of informing education. A major goal of educational neuroscience is to bridge the gap between the two fields through a direct dialogue between researchers and educators, avoiding the "middlemen of the brain-based learning industry". These middlemen have a vested commercial interest in the selling of "neuromyths" and their supposed remedies.

Childhood memory refers to memories formed during childhood. Among its other roles, memory functions to guide present behaviour and to predict future outcomes. Memory in childhood is qualitatively and quantitatively different from the memories formed and retrieved in late adolescence and the adult years. Childhood memory research is relatively recent in relation to the study of other types of cognitive processes underpinning behaviour. Understanding the mechanisms by which memories in childhood are encoded and later retrieved has important implications in many areas. Research into childhood memory includes topics such as childhood memory formation and retrieval mechanisms in relation to those in adults, controversies surrounding infantile amnesia and the fact that adults have relatively poor memories of early childhood, the ways in which school environment and family environment influence memory, and the ways in which memory can be improved in childhood to improve overall cognition, performance in school, and well-being, both in childhood and in adulthood.
