Cognitive Mechanisms of Control:
Our research aims to understand how our cognitive system helps us control our behavior to meet our goals. We focus on the processes that enable flexible and goal-directed behavior, specifically examining the relationship between working memory and cognitive control. Additionally, we explore how these capacities contribute to higher-order cognition.

Development of Self Control:
As individuals transition from pre-adolescence to adulthood, noteworthy transformations occur in the neural systems that underpin cognitive control. These alterations contribute to enhancements in the capacity for deliberate, goal-directed behavior. Our laboratory investigates the dynamics of decision-making by studying the asynchronous development of cognitive control and affective processing. We specifically concentrate on understanding the nuanced interplay between these systems to examine how the psychosocial context modulates their interaction.

In the context of an increasing prevalence of digital media technologies, including smartphones and social media, concerns have emerged regarding their potential impact on cognitive faculties and developmental processes. Our research encompasses a comprehensive examination of the intricate interplay among age, individual differences, and psychological and neurobiological functioning in the context of interactions with digital technology. Notably, our laboratory distinguishes itself by incorporating advanced measurements to systematically assess novel technology engagements.

Our research investigates the potential enhancement of adaptive functioning through interventions aimed at augmenting working memory capacity and refining attentional control. While previous studies imply task-specific gains with practice, emerging evidence suggests that systematic training in working memory and attention control may yield broader, more generalizable improvements. Within our laboratory, we employ novel, theory-driven methodologies for training these fundamental cognitive faculties. Our investigations assess the efficacy and extent of generalization resulting from diverse training modalities, advancing scientific understanding of heightened adaptive functioning through targeted cognitive interventions.

We are conducting a long-term study to explore how psychological and cognitive factors relate to smartphone and social media (SSM) use across different age groups. Our goal is to understand how these habits connect to decision-making, emotional development, and overall mental health. The study involves two main parts: first, we’re gathering initial insights during two in-person visits where participants will play psychology games, answer surveys, and undergo an MRI. Then, we’ll conduct follow-up assessments every 15 months to track changes over time.
We are currently recruiting participants and invite families to join our research. Your participation would contribute valuable insights.
Individuals vary in their sensitivity to social feedback, such as peer acceptance and/or rejection. Moreover, sensitivity to social feedback also changes over the course of development and is associated with psychiatric conditions like social anxiety and autism spectrum disorder. Remembering the peers one interacts with, in addition to the social feedback received from those peers, is therefore important, but remains an underexplored area of research. This project led by Ph.D. student Büşra Tanriverdi explores 1) how the brain responds differently to social acceptance and rejection, as well as social ambiguity, from peers, 2) how these neural signals of social feedback sensitivity change over the course of development, and 3) whether the neural markers of social sensitivity are related to how social information about the (accepting and/or rejecting) peers is later remembered. To study these questions, Büşra is using both behavioral and functional MRI (fMRI) experiments as well as self-report measurements such as Resistance to Peer Influence (RPI) and Rejection Sensitivity Questionnaire (RSQ).
Emerging generative AI models like ChatGPT have raised concerns about whether people can differentiate human and non-human (i.e., AI) content. Ongoing work seeks to examine whether people can differentiate between human and AI-generated (i.e., ChatGPT) content and whether psychological qualities such as fluid intelligence, response competition, empathy, and digital media habits relate to the ability to differentiate between human and AI materials. This project is led by Ph.D. student Steven Martinez.
Negative life experiences tend to remain strong in our memories, with potential to have detrimental effects on our mental health. The series of studies led by Ph.D. student Büşra Tanriverdi explores 1) how human hippocampus and cortex continues to process aversive versus neutral experiences after encoding, 2) how these experiences are then transformed into long-term representations in the brain, and 3) whether the differential processing of aversive and neutral experiences in the brain could help us understand the individual differences in experiences of traumatic symptoms, such as flashbacks and intrusions. To study these questions, Büşra is using both behavioral and functional MRI (fMRI) experiments as well as self-report measurements such as PTSD Check List for DSM-5 (PCL-5), emotion regulation and intolerance of uncertainty.
This project, led by Ph.D. student Steven Martinez, investigates the influence of memory accuracy on how memories are communicated. Research on subjective markers of memory has long established that confidence is often a poor marker of memory accuracy, but less is known about how linguistic patterns (i.e., word choice) relate to memory accuracy. Ongoing work uses natural language processing tools to characterize memory communication styles and determine whether these communication styles relate to memory accuracy. Relatedly, do memory communication styles influence perceptions of veracity, such as accuracy or honesty? We also explore how unique communication styles may be linked to perceptions of accuracy and honesty.
