The Fareri Lab

for Social Neuroscience and Decision-Making

Welcome to the Fareri Lab at Adelphi University, directed by Dr. Dominic Fareri. We are located in the Derner School of Psychology. Our lab investigates how social factors such as who we know and what we know about them change the way in which we learn, place value on others and social experiences and make decisions.


Research in the lab broadly focuses on understanding the way in which the social environment influences neural mechanisms that underlie our choices and ability to learn about others. We employ behavioral, computational (reinforcement learning), psychophysiological (skin conductance) and functional neuroimaging (fMRI) techniques to address these issues. Current and future work in the lab is centered around a few related areas of interest.

Social Relationships

Social psychological theories posit humans are intrinsically motivated to form close social connections with others. These close connections can occur within caregiving contexts (i.e., parents) or with peers (i.e., best friends) that we have come to know well over time (Fareri & Delgado, 2014, The Neuroscientist.). Evidence indicates that positive experiences both shared with others (Fareri*, Niznikiewicz* et al., 2012, Journal of Neuroscience) and earned in competition against others (Fareri & Delgado, 2014, Social Cognitive and Affective Neuroscience) may be more highly valued and informative when interacting with close friends compared with strangers, as represented by differential encoding in the brain's reward circuit. Successful social interactions (i.e., collaborations) with close others are indeed associated with a computational social reward value signal that scales with the value of a social relationship (Fareri*, Chang* & Delgado, 2015, Journal of Neuroscience). Current work in the lab is exploring how constructs such as perceived social support influences the value assigned to social experiences and how the value of close relationships changes in aging samples.

Decisions in Social Contexts

Many of the decisions we make occur within social contexts (e.g., deciding whether someone is trustworthy, choosing whether to make a risky or a safe choice). We often bring to such decisions important prior knowledge about interaction partners that is based on assumptions about social groups (Stanley, Sokol-Hessner, Fareri et al., 2012, Philosophical Transactions of the Royal Society of London: Biological Sciences), or previous experience from other situations that can impact the way in which we learn about their reputations (Fareri et al., 2012, Frontiers in Decision Neuroscience). Current studies in the lab are investigating how one's propensity to engage in risky choice may change depending on social context, and how positive and negative social experiences can change preferences for immediate gratification.

Atypical Experiences

Early & atypical life experiences can have a significant impact on brain development and future social and emotional behavior (Fareri & Tottenham, 2016, Developmental Cognitive Neuroscience). Indeed, a lack of stable caregiving and social support early in life can profoundly alter connectivity in neural networks important for processing reward and social value, which in turn is associated with increased levels of social difficulties (Fareri et al., 2017, Development and Psychopathology). Current work in the lab is beginning to investigate how interpersonal trauma (e.g., posttraumatic stress) influences the ability to derive reward value from social interactions and from social support figures.

Dominic is an Assistant Professor in the Derner School of Psychology at Adelphi University and is the Director of the undergraduate Neuroscience program. He is a Visiting Research Professor at the City College of New York and an affiliate of the Rutgers Center of Alcohol and Substance Use Studies. His research broadly focuses on understanding how the social world influences brain function and connectivity to shape the way in which we interact with others and develop relationships. Dominic received his Ph.D. in Psychology from Rutgers University, where he trained with Mauricio Delgado. He then completed postdoctoral training with Nim Tottenham at UCLA and Columbia University. In his spare time, Dominic enjoys spending time with his family and rooting for the Yankees.

Interested in participating in a study? We are currently recruiting healthy individuals between the ages of 18-35 for a number of paid studies. Contact us at farerilab [at]

Additionally, Drs. Dominic Fareri and Laura Brumariu are conducting a study to understand how children's close relationships shape the development of positive traits, such as being thankful and the ability to forgive. Families are compensated $40 for each child who participates and are entered in a raffle to win a $100 Amazon gift card! We are generally scheduling on weekdays after 3:30pm, and after 10am on Saturdays. Feel free to email or call 516-877-4822 if you have any questions!

  • We are seeking help from families with children between the ages of 9-14.
  • During the visit, children and parents will be asked to complete separate questionnaires that ask about their relationships, characteristics, and feelings.
  • Parents and children will be also interviewed separately that will be audiotaped.
  • We will also take a facial photo of the child and parent separately to be used in computer tasks, similar to playing a short game. We will delete both pictures at the end of the session and they will not be saved to any device!
  • Finally, the parent and child will be videotaped together discussing different topics and doing things together like playing a game and having conversations about common topics between parents and children (for example, discussing happy moments).
  • Importantly, your participation in this project would be voluntary, and all of the information you provide would remain confidential.
  • Due to the COVID-19 pandemic, we are taking extra precautions since everyone's safety is our top priority! Precautions include COVID-19 screeners, having temperatures taken, face masks, social distancing, disinfecting all surfaces in rooms, etc.

If you are an undergraduate student at Adelphi enrolled in General Psychology (PIA 101) or Psychological Research (PIA 245) and need to participate in experiments for credit, please visit the Adelphi Sona Systems site to view studies in our lab currently being run for credit.

If you are interested in gaining research experience and learning more about our work, we are always looking for motivated volunteers! Please send an email to Dr. Fareri at dfareri [at]
