A theoretician and experimentalist in neuroscience, Ezequiel Morsella investigates the neural differences between the conscious and unconscious aspects of human action control. Such control requires a medley of high-level, executive functions. All of his publications, experimental paradigms, and theoretical developments concern the nature of involuntary (versus voluntary) "entry into consciousness."
He carried out Ph.D. training at Columbia University and postdoctoral training at Yale University. Since his pre-college days, he has been focusing on the nature of the conscious (e.g., urges and working memory) and unconscious brain mechanisms in human action control. Morsella uses 'response interference paradigms,' including the Reflexive Imagery Task, to learn about the subjective aspects of action production (e.g., entry of urges into consciousness). He also uses 'delayed action tasks' to learn about the subjective aspects of working memory-based action control (e.g., imagery, sense of agency).
In all of his projects, Morsella has examined the mechanisms underlying the involuntary entry of information into consciousness (“involuntary entry”, for short). He developed the Reflexive Imagery Task in order to illuminate the nature of such entry.
In collaboration with Adam Gazzaley, Morsella is evaluating theoretical developments (e.g., Passive Frame Theory) regarding consciousness and the brain using behavioral and neuroimaging techniques. (Passive Frame Theory was introduced to the literature as a target article in Behavioral and Brain Sciences [see publication below].) In addition, with the assistance of the neurologist Stephen Krieger and colleagues at the UCSF Memory and Aging center, he is examining the implications of the theory for the study of disorders of awareness and disorders involving action selection (e.g., frontotemporal dementia).
