Daniel R. Berry, Ph.D.

I joined the psychology faculty at California State University San Marcos in the fall of 2017 after completing my Ph.D. in social psychology at Virginia Commonwealth University. My program of research adopts a multiple methodologies approach to understand the role of attention and awareness in social well-being. My most recent projects examine how mindfulness training enhances empathy and prosociality. I address these questions through lab-based and diary indicators of in vivo social behavior and through the lens of psychophysiology (i.e., EEG/ERP).

Welcome to the Social and Affective Psychophysiology Lab!   saplab

Our research program: Mindfulness has a number of definitions, but most converge to suggest that it is a receptive quality of attention to what one is presently experiencing. The SAP Lab implements a social and affective neuroscience approach to studying the wholesome social outgrowths of mindfulness and its training. Within this line of inquiry we have a number of research foci.

  • Does mindfulness training promote prosocial responsiveness toward others?  Kindness begins by paying attention to others in need, and contemplative traditions have long regarded mindfulness and related forms of mental training as promoters of virtuous behavior. Recent research from multiple labs that use secularized derviations of these trainings shows them to predict prosocial behaviors. Little is known, however, about what ingredients in these trainings promote prosociality. For example, some trainings include explicit instruction intended to cultivate compassion and care for others, making it difficult to isolate the effects of mindfulness itself. To address this question, we are conducting a meta-analysis that asks does mindfulness training without ethics-laden instruction promote prosocial behaviors? Related to this, recent work that Dr. Berry conducted while a graduate student suggests that short-term (4-day) mindfulness training, relative to sham-mindfulness medtiation training, increases real-world helping behavior toward racial outgroup members. This is important because despite our best efforts to promote intergroup harmony, interracial helping behavior continues to lag behind that directed twoard racial ingroup members. 

  • How does mindfulness training promote helping behavior toward others? Perhaps our most active line of inquiry focuses on the mechanisms of mindfulness in prosocial resposniveness. We have already conducted several experiments that suggest brief mindfulness training promotes helping behavior toward ostracized strangers and racial outgroup members, and do so because they feel concerned for them. We are currently conducting follow-up experiments to isolate motivations underlying mindfulness-induced helping behavior. Also, an ongoing experiment is examining whether mindfulness training modulates scalp-recorded event-related potentials to emotional face stimuli.

Other ongoing lines of inquiry include.

  • Can mindful attention promote intergroup prosociality?
  • Hypoegoic responses to social and existential threats

Dr. Berry encourages his graduate students and research assistants to form their own programmatic interests. Research questions on social and affective neuroscience, prosocial emotions and behaviors, mindfulness and its training, hypo-egoic phenomena, intergroup processes and relations, and stress resiliency are encouraged!

Please contact Dr. Berry directly ( for more information about graduate study in the SAP Lab.

Research Assistants: The SAP Lab is committed to the education and training of bright, motivated undergraduate and postbaccalaureate students; we depend heavily upon your hard work to complete lab studies. Our current research is focused on how practicing mindfulness can lead to more wholesome social relationships with others, particularly by promoting empathy and kindness. We use a multimethod approach in the lab to research these topics including EEG, behavioral, daily diary, and subjective responses. Getting involved as a volunteer or PSYC 498/499 student is a great way to see if psychological science is the right career path for you. As part of your training, we host workshops to help you gain admission into psychology graduate programs, medical school, and other professional training programs. The SAP Lab accepts new researchers each semester and carries between 10 - 20 students in total. Each research assistant given opportunity to help conduct 2 to 4 research projects a semester, and are offered a variety of tasks to choose from. Students can serve as experimenters, record and manipulate psychophysiological data, code and analyze data, conduct literature searches for meta-analyses, and even design and lead their own studies. If you are interested in the lab, please apply!.
