Bioecological Model
The bioecological model of development is a theoretical model of gene–environment interactions in human development. This model, first proposed by Urie Bronfenbrenner and Stephen J. Ceci, in 1994, is an extension of Bronfenbrenner's original theoretical model of human development, called ecological systems theory. Bronfenbrenner developed the bioecological model after recognizing that the individual was overlooked in other theories of human development, which were largely focused on the context of development (e.g., the environment). The bioecological model of human development can be applied to both children and maturing adults, and is thus a lifespan approach to development. The framework emphasizes the importance of understanding bidirectional influences between individuals’ development and their surrounding environmental contexts. In the bioecological model, in contrast to his earlier models, Bronfenbrenner also includes time (known as the chronosystem in his model) as an ...

Gene–environment Interaction
Gene–environment interaction (or genotype–environment interaction or G×E) is when two different genotypes respond to environmental variation in different ways. A norm of reaction is a graph that shows the relationship between genes and environmental factors when phenotypic differences are continuous. They can help illustrate GxE interactions. When the norm of reaction is not parallel, as shown in the figure below, there is a gene by environment interaction. This indicates that each genotype responds to environmental variation in a different way. Environmental variation can be physical, chemical, biological, behavior patterns or life events. Gene–environment interactions are studied to gain a better understanding of various phenomena. In genetic epidemiology, gene–environment interactions are useful for understanding some diseases. Sometimes, sensitivity to environmental risk factors for a disease are inherited rather than the disease itself being inherited. Individual ...

Kurt Lewin
Kurt Lewin ( ; 9 September 1890 – 12 February 1947) was a German-American psychologist, known as one of the modern pioneers of social, organizational, and applied psychology in the United States. During his professional career Lewin applied himself to three general topics: applied research, action research, and group communication. Lewin is often recognized as the "founder of social psychology" and was one of the first to study group dynamics and organizational development. A ''Review of General Psychology'' survey, published in 2002, ranked Lewin as the 18th-most cited psychologist of the 20th century. Biography Early life and education Lewin was born in 1890 into a Jewish family in Mogilno, County of Mogilno, Province of Posen, Prussia (modern Poland). It was a small village of about 5,000 people, about 150 of whom were Jewish. Lewin received an orthodox Jewish education at home. He was one of four children born into a middle-class family. His father owned a small gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecological Systems Theory
Ecological systems theory (also called development in context or human ecology theory) was developed by Urie Bronfenbrenner. It offers a framework through which community psychologists examine individuals' relationships within communities and the wider society. The theory is also commonly referred to as the ecological/systems framework. It identifies five environmental systems with which an individual interacts. The five systems * ''Microsystem'': Refers to the institutions and groups that most immediately and directly impact the child's development including: family, school, religious institutions, neighborhood, and peers. * ''Mesosystem:'' Consists of interconnections between the microsystems, for example between the family and teachers or between the child’s peers and the family. * ''Exosystem:'' Involves links between social settings that do not involve the child. For example, a child's experience at home may be influenced by their parent's experiences at work. A par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cross-sectional Data
Cross-sectional data, or a cross section of a study population, in statistics and econometrics, is a type of data collected by observing many subjects (such as individuals, firms, countries, or regions) at the one point or period of time. The analysis might also have no regard to differences in time. Analysis of cross-sectional data usually consists of comparing the differences among selected subjects. For example, if we want to measure current obesity levels in a population, we could draw a sample of 1,000 people randomly from that population (also known as a cross section of that population), measure their weight and height, and calculate what percentage of that sample is categorized as obese. This cross-sectional sample provides us with a snapshot of that population, at that one point in time. Note that we do not know based on one cross-sectional sample if obesity is increasing or decreasing; we can only describe the current proportion. Cross-sectional data differs from time ...

Longitudinal Study
A longitudinal study (or longitudinal survey, or panel study) is a research design that involves repeated observations of the same variables (e.g., people) over short or long periods of time (i.e., uses longitudinal data). It is often a type of observational study, although it can also be structured as longitudinal randomized experiment. Longitudinal studies are often used in social-personality and clinical psychology, to study rapid fluctuations in behaviors, thoughts, and emotions from moment to moment or day to day; in developmental psychology, to study developmental trends across the life span; and in sociology, to study life events throughout lifetimes or generations; and in consumer research and political polling to study consumer trends. The reason for this is that, unlike cross-sectional studies, in which different individuals with the same characteristics are compared, longitudinal studies track the same people, and so the differences observed in those people are less like ...

Ecological Validity
In the behavioral sciences, ecological validity is often used to refer to the judgment of whether a given study's variables and conclusions (often collected in lab) are sufficiently relevant to its population (e.g. the "real world" context). Psychological studies are usually conducted in laboratories though the goal of these studies is to understand human behavior in the real-world. Ideally, an experiment would have generalizable results that predict behavior outside of the lab, thus having more ecological validity. Ecological validity can be considered a commentary on the relative strength of a study's implication(s) for policy, society, culture, etc. This term was originally coined by Egon Brunswik and held a very narrow meaning that has since been conceptually modified. He regarded ecological validity as the utility of a perceptual cue in predicting a property (basically how informative the cue is). For example, the movement of leaves on trees is a perceptual cue to how windy it ... [...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] |
Observational Learning
Observational learning is learning that occurs through observing the behavior of others. It is a form of social learning which takes various forms, based on various processes. In humans, this form of learning seems to not need reinforcement to occur, but instead, requires a social model such as a parent, sibling, friend, or teacher with surroundings. Particularly in childhood, a model is someone of authority or higher status in an environment. In animals, observational learning is often based on classical conditioning, in which an instinctive behavior is elicited by observing the behavior of another (e.g. mobbing in birds), but other processes may be involved as well. Human observational learning Many behaviors that a learner observes, remembers, and imitates are actions that models display and display modeling, even though the model may not intentionally try to instill a particular behavior. A child may learn to swear, smack, smoke, and deem other inappropriate behavior acceptabl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Developmental Psychology
Developmental psychology is the science, scientific study of how and why humans grow, change, and adapt across the course of their lives. Originally concerned with infants and children, the field has expanded to include adolescence, adult development, aging, and the entire lifespan. Developmental psychologists aim to explain how thinking, feeling, and behaviors change throughout life. This field examines change across three major dimensions, which are physical development, cognitive development, and social emotional development. Within these three dimensions are a broad range of topics including motor skills, executive functions, morality, moral understanding, language acquisition, social change, personality, emotional development, self-concept, and identity formation. Developmental psychology examines the influences of nature ''and'' nurture on the process of human development, as well as processes of change in context across time. Many researchers are interested in the inter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lev Vygotsky
Lev Semyonovich Vygotsky (russian: Лев Семёнович Выго́тский, p=vɨˈɡotskʲɪj; be, Леў Сямёнавіч Выго́цкі, p=vɨˈɡotskʲɪj; – June 11, 1934) was a Soviet psychologist, known for his work on psychological development in children. He published on a diverse range of subjects, and from multiple views as his perspective changed over the years. Among his students was Alexander Luria and Kharkiv school of psychology. He is known for his concept of the zone of proximal development (ZPD): the distance between what a student (apprentice, new employee, etc.) can do on their own, and what they can accomplish with the support of someone more knowledgeable about the activity. Vygotsky saw the ZPD as a measure of skills that are in the process of maturing, as supplement to measures of development that only look at a learner's independent ability. Also influential are his works on the relationship between language and thought, the developmen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
