Psychological research and practice

There is an extremely intricate relationship between psychological research and practice. Psychology borrowed scientific methodology to study non-animate objects like rocks for the exploration of the human mind, akin to natural sciences (Giorgi, 1970; Valle & Halling, 1989). However, this mainstream tradition encountered many difficulties because, unlike other disciplines such as physics, psychologists encounter “very messy” data sets due to substantial individual differences in their research. Furthermore, psychology is currently experiencing what is known as a “replication crisis” (Amrhein et al., 2019; Earp & Trafimow, 2015; Maxwell et al., 2015; Shrout & Rodgers, 2018; Stroebe & Strack, 2014), where the replicability of famous experiments that underpinned the theories taught in psychology textbooks is being questioned.

This crisis prompts us, as science-practitioners, to reconsider the trade-off between experimental control and real-world application, also known as ecological validity (Matthews, 2000). Often, the more relatable a psychological phenomenon is to everyday life, the less replicable it becomes in a laboratory setting because our daily lives are filled with numerous latent variables that potentially create different relationships among them (e.g., additive, interactive, correlating, etc.). Thus, the replicability of the investigated phenomena significantly improves when we focus on “dry” topics, such as the millisecond bottleneck of visual selective attention (Raymond et al., 1992).

Despite the current state of affairs, I am cautiously optimistic that the deliberate shift towards experimental control will reveal more about the causality of pressing mental health issues than ecological validity theory suggests. For instance, we are beginning to reexamine how we analyze data even for highly replicated phenomena, such as attentional capture (Turatto, 2023). This trend might help us better understand the origins of critical individual differences in how we interpret the world, as seen in cases like autism (Sinha et al., 2014).

Please stay tuned for the latest developments in research on this front. I believe that a careful return to basic science will help unravel some of the puzzling phenomena we encounter in everyday life.
