Quick Answer: What Is A Sequential Study In Psychology?

A research method that combines cross-sectional and longitudinal research by considering a number of different age groups and examining them at several points in time is called sequential research.

What is sequential research example?

For example, an investigator using a cross-sequential design to evaluate children’s mathematical skills might measure a group of 5-year-olds and a group of 10-year-olds at the beginning of the research and then subsequently reassess the same children every 6 months for the next 5 years.

What is the difference between cross-sectional and sequential?

With cross-sectional, we look at a whole bunch of groups right now. With sequential, we look at a whole bunch of groups over time.

What is a cohort sequential study in psychology?

an experimental design in which multiple measures are taken over a period of time from two or more groups of different ages (birth cohorts). Such studies essentially are a combination of a longitudinal design and a cross-sectional design. Also called accelerated longitudinal design.

What is time sequential study?

an experimental design to separate age effects from time-of-measurement and cohort effects (i.e., to determine if the results obtained are age-related only). In a time-sequential design, a second age group is added to a time-lag design, and two or more cross-sectional comparisons are made at different times of testing.

What is a longitudinal study example?

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 longitudinal design in psychology?

A longitudinal design is one that measures the characteristics of the same individuals on at least two, but ideally more, occasions over time. In following a group of individuals over time, one might choose to study a particular birth cohort, so that all the research subjects share a single age and historical context.

What is sequential research explain?

Definition (1): A research method that combines cross-sectional and longitudinal research by considering a number of different age groups and examining them at several points in time is called sequential research.

Why is a sequential design desirable when possible?

Sequential designs are also appealing because they allow researchers to learn a lot about development in a relatively short amount of time. In the previous example, a four-year research study would provide information about 8 years of developmental time by enrolling children ranging in age from two to ten years old.

What are the strengths and weaknesses of cross sequential study?

Strengths & Weakness of Sequential Study

  • Strength: Mitigated Cultural Variations. By consistently studying the same group of people, researchers are able to eliminate cultural or demographic factors from their findings.
  • Weakness: Participant “Mortality”
  • Strength: Observing Changes.
  • Weakness: Poor Causational Analysis.

What is an accelerated longitudinal design?

An accelerated longitudinal design (ALD) is a more structured multiple cohort design that takes multiple single cohorts, each one starting at a different age. Figure 1 represents an ALD covering ages 0–7 with three cohorts, four annual measurements per subject and an overlap of two measurements between cohorts.

What is a cross-sectional study in psychology?

A cross-sectional study involves looking at data from a population at one specific point in time. For example, researchers studying developmental psychology might select groups of people who are different ages but investigate them at one point in time.

Is longitudinal and cohort study the same?

Longitudinal research is a type of correlational research that involves looking at variables over an extended period of time. Cohort study is a particular type of longitudinal study which involves comparison groups (exposed group vs non-exposed group to the factor in question).

What is meant by the term longitudinal?

1: placed or running lengthwise The insect’s back is black with yellow longitudinal stripes. 2: of or relating to length or the lengthwise dimension the longitudinal extent of the building.

How long is a cross sequential study?

Rather than studying particular individuals across that whole period of time (e.g. 20–60 years) as in a longitudinal design, or multiple individuals of different ages at one time (e.g. 20, 25, 30, 35, 40, 45, 50, 55, and 60 years) as in a cross-sectional design, the researcher chooses a smaller time window (e.g. 20

How long do longitudinal studies last?

How long is a longitudinal study? No set amount of time is required for a longitudinal study, so long as the participants are repeatedly observed. They can range from as short as a few weeks to as long as several decades. However, they usually last at least a year, oftentimes several.
