One needs to look no further than the rich set of articles in this special issue to know that Feature Integration Theory (FIT) continues to be one of the most influential sets of ideas in cognitive psychology. From research on multi-sensory integration to depression, the seeds of Anne Treisman’s theory have spread far and wide.

However, there is one paper I would like to highlight that, rather than reviewing the research that has come from FIT, describes the research that inspired it – putting it in an ‘academically historical’ context, if you will. First, I will summarize some key insights from the paper. Following this, I will utilize my perspective as a current graduate student to ask an important question: what can young scientists gain from learning about the historical academic context in their own lives and careers?

In their 2019 AP&P paper, Kristjánsson and Egeth detail the many different lines of research that laid the groundwork for Anne Treisman’s proposal of FIT. Take attention, for example. FIT proposes that focal attention acts as the “glue” that binds individual features (e.g., shape, color) of an item together into one holistic representation. Kristjansson and Egeth explain that this innovative idea was inspired at least in part by research that emerged from the cognitive revolution in the 1950s, including Broadbent’s proposal of attention as a filter 20 years before FIT emerged (and interestingly, Broadbent’s proposal in and of itself was a response to problems faced by radio operators during WWII).

Another central tenet of FIT – the idea that we process certain features in parallel – was inspired by the pioneering work in visual neurophysiology by Hubel and Wiesel. These researchers, and others, showed that certain brain areas respond preferentially not only to particular features (i.e. orientation), but to feature properties and location (i.e. this specific orientation in this location). An additional significant yet lesser-known influence on FIT was Garner’s investigation of which features could be processed independently and which could not. In another example, Kristjánsson and Egeth traced back the seemingly ubiquitous concept of sequential stages of processing, to earlier work by Sternberg, who was himself influenced by Donders back in the mid-late 19^th century. Clearly, FIT did not arise ‘out of the blue,’ but rather from a rich history of research that preceded it.

Rarely does one come across a paper dedicated entirely to the etiology of one particular idea. It is this very concept that makes this paper so insightful and applicable to young scientists and graduate students such as myself. The context that the authors lay out usually only comes after studying and researching in the field for many years if not decades. If graduate students – who are essentially children in the academic timeline of their careers – want to learn about the historical academic context that led to their own research ideas and that of others, then we must purposefully invest our time and commit to reading the works of scholars such as Kristjánsson and Egeth who have such extensive knowledge of the field.

Drawing upon the foundations of this paper, I will next outline two arguments for why busy grad students (myself included) would benefit from adding “learn historical academic context” to their ‘to do’ list. Specifically, I argue that reading papers such as these can both teach us where Big Ideas come from and help us find our own research trajectory.

Context teaches where Big Ideas come from

Like many aspiring young scientists, I have lofty goals to publish in journals with names that even my grandmother would recognize or to develop the next theory to send waves throughout the field. Many of us, perhaps, are guilty of hoping that the next Big Idea will come to us in our dreams or in the shower. However, in 99% of cases (i.e. unless you’re Srinivasa Ramanuja), that’s not how it works. That being said, we can glean from Kristjánsson and Egeth’s paper how one might generate an influential idea by looking at the context in which such an idea arose.

First of all, the authors remind us that no idea is isolated. FIT – one of the most influential ideas to hit cognitive psychology – wasn’t created within a vacuum. In fact, quite the opposite was the case. The theory was a very active response to the conceptual and experimental findings of the last several decades. Kristjánsson and Egeth go so far as to say the plethora of discoveries leading up to that moment “cried out for an encompassing framework,” which FIT provided.

Therefore, as grad students, or for that matter as anyone who wants to know where Big Ideas like FIT come from, this paper provides a roadmap for doing just that. By cultivating both a deep understanding of the developments around and before us, as well as the skills to be able to synthesize that information, we can equip ourselves with the tools to uncover the next Big Idea.

Context helps to form a personal research trajectory

Kristjánsson and Egeth’s paper beautifully depicts the trajectory of Anne Treisman’s work as it led to FIT, weaving together key insights from others on the way. As graduate students just starting to pave our own paths, wielding knowledge of the stepping stones available in the field helps us to mentally organize our place in the narrative unfolding around us. Visualizing research in terms of exponential growth, where one idea leads to many more, which in turn leads to many more, offers a path forward that makes sure our research is at the forefront of what is being done while also taking into account and respecting what has been done in the past.

Anne Treisman was a pioneering figure in cognitive psychology. She was also known as a caring mentor and friend to many. As the next generation of scientists, one way we can honor that legacy is to make a point to seek out and understand where people’s ideas come from and how the past has influenced them. I think this practice will serve to benefit us as scientists, and as future leaders and mentors, too.
