Empirically Identifying and Computationally Modeling the Brain–Behavior Relationship for Human Scene Categorization

Agnessa Karapetian,
Antoniya Boyanova,
Muthukumar Pandaram
et al.

Abstract: Humans effortlessly make quick and accurate perceptual decisions about the nature of their immediate visual environment, such as the category of the scene they face. Previous research has revealed a rich set of cortical representations potentially underlying this feat. However, it remains unknown which of these representations are suitably formatted for decision-making. Here, we approached this question empirically and computationally, using neuroimaging and computational modelling. For the empirical part, we … Show more

“…This is consistent with the observation that masking reduces firing duration in single cells in monkey IT 100,101 , and that masking reduces persistence in the visual representations of occluded objects in humans 9 . Together this supports the view that recurrence plays an active role in accruing and maintaining important information online for further processing and decision making 45,[102][103][104][105][106] .…”

“…One participant was excluded from the analyses due to incidental findings consistent with a recognized neurological disorder, resulting in a final sample of 29 participants (mean age = 24.4, SD=3.7, 21 female, 8 male). The final sample size is comparable or larger than previous studies using decoding approaches for relating brain data to behavioral data (Carlson et al, 2014;Grootswagers et al, 2018;Karapetian et al, 2023;Ritchie & Op de Beeck, 2019). The study was approved by the ethics committee of Freie Universität Berlin and was conducted in accordance with the Declaration of Helsinki.…”

“…C) Behavioral paradigm. Behavioral data was acquired with different sets of participants in either a previous experiment (Karapetian et al, 2023) or in an independent behavioral experiment with analogous trial structure but a different behavioral task. In a given trial, a scene image was presented for 500ms, overlaid with a blue or green fixation cross (only for the manmade/natural and fixation tasks), followed by the presentation of a white fixation cross for a variable time between 500-700ms.…”
