Size (mostly) doesn’t matter: the role of set size in object substitution masking

Conscious detection and discrimination of a visual target stimulus can be prevented by the presentation a spatially nonoverlapping, but temporally trailing, visual masking stimulus. This phenomenon, known as object substitution masking (OSM), has long been associated with spatial attention, with diffuse attention seemingly being key for the effect to be observed. Recently, this hypothesis has been questioned. We sought to provide a definitive test of the involvement of spatial attention in OSM by using an eight-alternative forced choice task under a range of mask durations, set sizes, and target/distractor spatial configurations. The results provide very little evidence that set size, and thus the distribution of spatial attention, interacts with masking magnitude. These findings have implications for understanding the mechanisms underlying OSM and the relationship between consciousness and attention.     

Personality Process-Structure Duality: Reply to Two Commentaries

In two commentaries, Kostromina and Grishina (2018) and Mironenko (2018) offered constructive thoughts and questions in response to an article by Giordano (2018, Culture & Psychology, 23, 502–518) on the merits of an approach to understanding individual personality that focuses on the processes rather than structures of personality. In this reply, the authors seek to clarify some of the points made in the original article. The authors also describe a personality process-structure duality, whereby personality is conceptualized in terms of processes or structures based on the methods used to study it. If the goal is to understand the dynamic and emergent properties of individual personality, the authors continue to argue for the merits of a process-centric approach and the avoidance of structural thinking.
