Which technique of developmental researchers requires a significant expenditure of time as a researcher waits for the participants to get older? longitudinal research cross-sectional research applied research empirical research?

The correct answer is longitudinal research.

Longitudinal research is an observational research method in which data is collected from the same subjects repeatedly over a long period of time. As the participants get older, these projects can extend for years, or even decades.

Further explanation

Longitudinal research is one research design that has unique characteristics. Longitudinal research is carried out in a relatively long time. Costs are also often not insignificant because it involves monitoring developments or changes that occur in the study sample.

Longitudinal research is research that uses data with a long time span. How long is the length of time meant is very relative. However, the emphasis of actual longitudinal research is on the extension or extension of the survey conducted. The extension is periodic.

So, longitudinal research can also be understood as an extension of periodic survey research. At least, the survey was conducted twice with a timeframe determined from the beginning. Data collection techniques in this study usually use questionnaires or structured interviews. The researcher determines the time span between when the data was first taken from the sample, when the data was taken again, until the third time and so on depends on how long the time span is.

To conduct longitudinal research, we first conduct a survey with questionnaires and / or interviews with young people selected as samples. The participants or young people's identities are recorded carefully and neatly stored in the archives. The first survey was conducted with well-developed variables.

The results of the second, third and so forth surveys will show changes in what happens to these young people, which may be in the third survey and so on are no longer classified as young people. With this research design, changes in the characteristics of violence as the focus of the study are very likely to be known.

if interdependence implies a two-way dependence, and if each partner is equally dependent on the other for success, then there is an equal commitment to the making the partnership successful. the advantage is sustainability of the relationship, the disadvantage is that decisions are "democratic" and therefore may take longer to reach and more likely to be a compromise (which is not always the best solution). as the interdependence moves away from equality, the decisions become more influenced by the more independent partner. in the extreme the relationship becomes more dictatorial and more like "master-slave". generally the relationship has less commitment in both directions and is more likely to be temporary.

if one generalizes (and one shouldn't), equity partnerships, which is probably what is implied by interdependence, can be slow to progress or change but durable. the extreme alternative, independent-dependent partnerships tend to be efficient but more fragile.

hope this but you will have to site your own evidence. : )
