Perception and Cognition (PAC) Lab focuses on normal and pathological cognitive mechanisms that govern our behavior. We use digital and extended reality interfaces to simulate physical reality and associated conditions and ask participants to perform tasks using a given virtual interface. We engage with young adults between 18-35 years and use cross-sectional and longitudinal experimental designs. We examine qualitative and quantitative responses using survey, interview, behavioral, psychophysical, eye-tracking, and physiological methods.
For example, we investigate the role of emerging technologies like extended reality in shaping our perception, cognition, and action; the relationship between embodied experience in extended reality and perception and construction of reality; how VR can enable us to experience self and emotion; how depression and associated comorbidities are related to concept coding; the relation between depression and cognitive functions; the association between auto-immune diseases and cognitive, social, and psychological health; the role of modality in concept formation and creative production; or how user interface design or mental model influences user's action/ responses to name few.

Priyanka Srivastava, PI, delivered an invited talk, titled, What Do Head Scans Reveal About Depression? Insights from VR 3600 Psychomotor Assessment. at 76th Annual National Conference of the Indian Psychiatric Society (ANCIPS) 2025, 22-25 January, 2025.
Priyanka Srivastava, PI, co-lead a session on art and science titled The multiverse of the Eye, at the Hyderabad Literary Festival, 2025. She collaborated with vision scientist, Dr. Shrikanth Bharadwaj from LVPEI (https://www.lvpei.org/about-us/our-team/research/shrikant-bharadwaj) and two artists, Priyanka Aelay and Sameera Maruvada to explore rich interdiscplinary dialgoues through the lenses of Art, Vision Science, and Psychology, and Emotion. https://www.hydlitfest.org/ .
Warm wishes and congratulations to PAC members Nishanth Arcot and Pragya Singhal on receiving their MS degree during the 2024 Convocation 👏
Pragya's research presented first study on understanding cognitive and psychological health issues associated with Lupus diesease in Indian patients. We have successfully completed phase I.
Additionally, Manas Kabre has submitted his thesis in July 2024.
PAC team had a visitor, Prof. Greg Seigle, Pittsburg University, to discuss their research on depression and emotion.
Figure: Comparative VR 3600 exploration of pleasant [(a), (e)] and unpleasant [(d), (h)] affective video experiences. The video names with their indices are as follows: (a) “Getting licked by a cow in Ireland (26)”, (e) “Tahiti Surf (70)”, (d) “Abandoned City (3)”, and (h) ”Zombie Apocalypse Horror (21)”. (b), (f), (c) & (g): Corresponding 3D region-wise plots of VR head-movement data while exploring VR 360° videos by normal healthy participants (blue = region 1, yellow = region 2, green = region 3, red = region 4).
FEEL Project aims to understand the relationship between emotion-attention-and-depression and develop a unifying model for cognition and depression. We use multiple modalities, like digital and VR technologies, smart watches or physiological sensors, and eye-tracking to analyse and identify depression proneness or risk for depression. We use the bio-psycho-social model (NIMH, US) of mental health assessment, treatment, and research perspectives.
Digital Health Screening project aims to develop a ‘cognitive and psychological screening battery’ to screen cognitive and psychological health. Currently, we are using some digital tests to characterize direct and indirect impact of COVID on individual psychological and cognitive wellbeing; and to characterize social, psychological, and cognitive dysfunctions associated with autoimmune diseases like systemic Lupus Erythematosus (Lupus). (See right for example)
Enhance Vision project aimed to evaluate the effect of virtual 360-degree display designs on constructing as real as possible local area and local situational awareness around the remote unmanned vehicle or robot.
The project had two major goals:
1.Evaluate the effect of 360-degree display designs on constructing remote local area awareness - funded by CSRI, DST.
2.Assess Soldiers’ Cognitive and Ergonomic Profile and develop intervention protocols for effective training to use the optimal 360-degree user-interface- funded by INMAS, DRDO.
Creative Cognition investigates the relation between intelligence, abstraction, and creative thinking. The projects focus on role of abstract thinking, mental representation, mental flexibility, concept coding, and attention in creative thinking. Currently, the ongoing projects aim to understand the role of modality in concept formation, abstraction, and creative thinking; role of attention flexibility on creative reasoning; and role of cognitive strategies on creative reasoning.
