New Publications

Just updated my CV - here's a few new publications and conferences! The weird thing about the automatic CV updater I wrote is that you can't really predict what order the same year publications are going to be in - not that it matters in general, but it's an interesting side effect.

Also, super proud - both of these are student theses turned papers:

Maxwell, N.P. & Buchanan, E.M. (2019).Investigating the interaction of direct and in-direct relation on memory judgments and retrieval.Cognitive Processing, X, XX–XX. doi:10.1007/s10339-019-00935-w [https://osf.io/fcesn/]

Abstract: This study examined the interactive relationship between two measures of association (direct and indirect associations) when predicting relatedness judgments and cued-recall performance. Participants were recruited from Amazon's Mechanical Turk and were given word pairs of varying relatedness to judge for their semantic, thematic, and associative strength. After completing a distractor task, participants then completed a cued recall task. First, we sought to expand previous work on judgments of associative memory (JAM) to include semantic and thematic based judgments (judgments of relatedness, JOR), while also replicating bias and sensitivity findings. Next, we tested for an interaction between direct and indirect association when predicting participant judgments while also expanding upon previous work by examining that interaction when predicting recall. The interaction between direct and indirect association was significant for both judgments and recall. For low indirect association, direct association was the primary predictor of both judgment strength and recall proportions. However, this trend reversed for high indirect association, as higher levels of indirect relation decreased the effectiveness of direct relation as a predictor. Overall, our findings indicate the degree to which the processing of similarity information impacts cognitive processes such as retrieval and item judgments, while also parsing apart the underlying, interactive relationship that exists between the norms used to represent concept information.

Herr, D. & Buchanan, E.M. (2019).Generativity and other buffers of death awareness in first responders with PTSD.Anxiety, Stress, & Coping, X, XX–XX. [https://osf.io/dp3jz/]

Abstract:

Background and Objectives: Anxiety buffer disruption theory (ABDT) is an application of terror management theory to posttraumatic stress disorder (PTSD). ABDT predicts that posttraumatic stress reactions occur when buffers of awareness of death, such as meaning in life, self-esteem, and social intimacy, fail to suppress overwhelming death-anxiety. In this study, we hypothesized that generativity may also serve as an effective buffer of awareness of death and PTSD.

Design: The present study investigated the presence of anxiety buffering disruption in first responders with a spectrum of posttraumatic stress via a mediation path model of self-report measures of PTSD symptoms, anxiety buffer variables, and death-though accessibility.

Methods: To investigate the role of anxiety buffering in PTSD, a sample of 986 first responders completed self-report measures of PTSD symptoms and anxiety buffer variables in randomized order, and a death-thought accessibility measure following random assignment to mortality salience (n = 290) or control (n = 302) conditioning.

Results and Conclusion: While results indicate PTSD symptoms have a small relation to increased awareness of death, results indicate anxiety buffering variables did not mediate the relation between PTSD symptoms and awareness of death. Nonetheless, generativity and meaning in life, self-esteem, and social support were significant predictors of lower levels of PTSD.
