Timescale
This is the landing page for everything related to the timescales of constructs of interest.
To ensure the measurement of a process aligns with the theory and research questions we have, it is paramount to determine the timescale at which the process is assumed to unfold, and match this with the timescale at which we observe the process.
To illustrate the importance of considering the timescale of a process, consider:
- The answer to a research question may differ depending on the timescale considered.
Louise studies how specific actions from the parents affect the behavior of their children. When focusing on how to best handle the tantrums of a toddler who demands a cookie, it becomes clear that in the short-run, it is beneficial to give the toddler a cookie: They calm down and the tantrum seems to dissipate. But in the longer run, when the parent keeps offering cookies whenever the toddler is upset, the number of tantrums increases and the toddler is demanding cookies much more frequently and more fiercely. Thus, while providing a cookie represents an instant gratification at the lower timescale, repeatedly providing a cookie teaches the child to behave in a certain way to get it their way.
- Different research questions may require studies at different timescales, even if they are about the same general constructs.
- It may be the case that there are various processes that operate at different timescales, that all contribute to our measurements (whether we like it or not). For instance, at a shorter timescale (e.g., minute-to-minute), a regulatory process may be at play, while at a longer timescale (e.g., week-to-week), a developmental process may be taking place.
Steve is interested in studying the relation between accuracy and speed in a typing task. When considering the relation between accuracy and speed at a short timescale (minute to minute), it becomes clear that these variables are negatively correlated: Tasks on which a participant types faster are characterized by more mistakes. Yet, when allowing the participant to train a lot, it becomes clear that both speed and accuracy increase over time: This shows the effect of learning, which takes place at a longer timescale.
