Research

My research interests are diverse and focus in two different fields of psychology: cognitive and social. In my primary field of research, cognitive psychology, I use methods of cognitive psychology, cognitive neuroscience and cognitive neuropsychology to study the relationship between working memory (WM), language and attention. In my secondary field of research, social psychology, I study gender discrimination. Specifically, I have worked on projects evaluating gender discrimination in medicine and science. I will discuss each of these in turn, with a focus on my primary field of research.

My research in cognitive psychology has focused on higher-level cognitive processes: WM, language and attention. While there are many theories of language, many theories of WM, and many theories of attention, few theories have looked at integrating these highly connected cognitive processes. My research is based in attempts to integrate these processes. I approach WM from a multiple capacities perspective-that is, WM can be subdivided in domain specific components, such as visual, semantic and phonological WM.  Specifically, my research investigates how semantic and phonological WM relate to language and how they might be impaired in a population of individuals with aphasia. Martin and colleagues proposed one of the primary models that have tried to integrate language and WM (Martin, Shelton & Yaffee, 1994; Martin, Lesch & Bartha, 1999).

In this field of research, I have: investigated the scope of planning in language production (e.g., Martin & Freedman, 2001; Smith & Wheeldon, 1999); evaluated dissociations in semantic and phonological WM deficits; examined the relationship of semantic and phonological WM to language production in acute and chronic aphasia patients;  tested the Dual Route Theory of Language (e.g., Hickok & Poeppel, 2001); investigated the relationship between WM and attention (i.e., attempts at integrating embedded-processes and multiple capacities approaches to WM); and performed a psychometric study evaluating a novel way to measure semantic WM.

As mentioned previously, I also do research in social psychology. Specifically, I have worked on projects evaluating gender discrimination in medicine and science. Many studies have shown that, even given the exact same information with only the first name changed to represent a male or female, women are rated as less competent, less likely to be hired and offered less money for the exact same job as compared to men. Research has also shown that in letters of recommendation, women are more likely to be described in communal terms whereas men are more likely to be described in agentic terms (Madera, Hebl & Martin, 2009) and that this was related to hiring decisions. It was hypothesized that this might contribute to the relative disparity between men and women in science fields. Current research is evaluating this hypothesis by looking at CV’s, letters of recommendation, cover letters, search committee comments and hiring decisions in medicine and science. This research is still in progress.

I plan to continue working in these two different fields of psychology for the entirety of my career. I will focus the bulk of my efforts in cognitive neuroscience while collaborating on  projects investigating discrimination.
