Developmental psychology is the scientific study of how and why human beings change over the course of their life. Originally concerned with infants and children, the field has expanded to include adolescence, adult development, aging, and the entire lifespan.

Developmental Psychology Studies Humans Across the Lifespan. Developmental psychologists focus on human growth and changes across the lifespan, including physical, cognitive, social, intellectual, perceptual, personality and emotional growth.

Life-span developmental theory concerns. the study of individual development, or ontogenesis, from conception to death. A key assumption of this theory is that develop- ment does not cease when adulthood is reached (Baltes, Lindenberger, & Staudinger, 1998, p. 1029)1.

A longitudinal study can be used to discover relationships between variables that are not related to various background variables. This observational research technique involves studying the same group of individuals over an extended period.

What is the microgenetic method? The microgenetic approach examines change as it occurs, thus attempting to identify and explain its underlying mechanisms. It involves taking repeated measurements from the same participants over the course of transition in the domain of interest.

The 1970 British Cohort Study, which has collected data on the lives of 17,000 Brits since their births in 1970, is one well-known example of a longitudinal study.

There are a range of different types of longitudinal studies: cohort studies, panel studies, record linkage studies. These studies may be either prospective or retrospective in nature.

A longitudinal study, like a cross-sectional one, is observational. So, once again, researchers do not interfere with their subjects. However, in a longitudinal study, researchers conduct several observations of the same subjects over a period of time, sometimes lasting many years.

The biggest problem in longitudinal research comes from changing historical context. Seeks to understand how and why people of all ages and circumstances change or remain the same over time. a time when a certain type of development is most likely, although it may still happen later.

However, the longitudinal survey also has significant problems, notably in confounding aging and period effects, delayed results, achieving continuity in funding and research direction, and cumulative attrition.

From Wikipedia, the free encyclopedia. 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).

Longitudinal studies are a method of observational research. The primary disadvantage of using longitudinal studies for research is that long-term research increases the chances of unpredictable outcomes. If the same people cannot be found for a study update, then the research ceases.

List of Advantages of Longitudinal Studies

• They are effective in determining variable patterns over time.
• They can ensure clear focus and validity.
• They are very effective in doing research on developmental trends.
• They are more powerful than cross-sectional studies.
• They are highly flexible.

They require enormous amounts of time. Another huge drawback to any longitudinal study is the great amount of time it needs to collect all the data that is needed. Usually, it takes a long period of time to gather results before you can start making patterns.

Longitudinal data enable us to: Track children’s development throughout childhood and teenage years, to adulthood and beyond – including influences, aspirations and cognitive outcomes. Study the links between family background, educational achievements and later outcomes.

A longitudinal study is a prospective observational study that follows the same subjects repeatedly over a period of time. Instead of following individuals, this study follows whole households of people through time.

Information gathered over the time of undertaking a longitudinal study will enable an early years practitioner to: find out about different aspects of a childs development. identify ways in which children learn. reflect on what providers must do to promote development and learning and, thus further develop good …

Types of surveys that use a longitudinal study Through these surveys, businesses or organizations can learn what customers want and what they will discard. This study can be carried over time to assess market trends repeatedly, as they are volatile and tend to change constantly.

Attrition is one of the major methodological problems in longitudinal studies. It can deteriorate generalizability of findings if participants who stay in a study differ from those who drop out.

Longitudinal studies can help researchers to distinguish between changes that happen as people get older, known as ‘age effects’, and generational differences that reflect the historical, economic and social context within which different cohorts grew up, known as ‘cohort’ or ‘generational’ effects.

Longitudinal research is occasionally used to study unique individual cases. Longitudinal case studies are studies that gather copious amounts of data on a single person or small group of people. For example, a five-year study of children learning to read would be a cohort longitudinal study.

What is another word for longitudinal?

Longitudinal study designs Repeated cross-sectional studies where study participants are largely or entirely different on each sampling occasion; Prospective studies where the same participants are followed over a period of time.

In prospective studies, individuals are followed over time and data about them is collected as their characteristics or circumstances change. Birth cohort studies are a good example of prospective studies. In retrospective studies, individuals are sampled and information is collected about their past.

Prospective Cohort Studies: The Framingham Heart Study, the Nurses Health Study, and the Black Women’s Health Study are good examples of large, productive prospective cohort studies. In each of these studies, the investigators wanted to study risk factors for common chronic diseases.

Retrospective example: a group of 100 people with AIDS might be asked about their lifestyle choices and medical history in order to study the origins of the disease. Prospective example: a group of 100 people with high risk factors for AIDS are followed for 20 years to see if they develop the disease.

The advantages of retrospective cohort studies are that they are less expensive to perform than cohort studies and they can be performed immediately because they are retrospective. Also due to this latter aspect, their limitation is: poor control over the exposure factor, covariates, and potential confounders.

Key Concept: The distinguishing feature of a retrospective cohort study is that the investigators conceive the study and begin identifying and enrolling subjects after outcomes have already occurred.

An example of a retrospective cohort study will be interviewing a cohort of people who are HIV positive, ask about their lifestyle choices and medical history to study the origins of the disease.

There are two types of retrospective study: a case–control study and a retrospective cohort study. A retrospective study design allows the investigator to formulate hypotheses about possible associations between an outcome and an exposure and to further investigate the potential relationships.
