Stanciu O., & Fiser J. (2024) Does active learning lead to better teaching of novel perceptual categories? Proceedings of the Annual Meeting of the Cognitive Science Society (46) [Abstract]
To be efficient, both active learners and teachers need to be able to judge the relative usefulness of a piece of information for themselves or for their students, respectively. The current study assessed whether experience of active learning facilitates subsequent teaching from imperfect knowledge. Following a visual category learning task, dyads (N=40) of active and yoked […]

Transfer learning, the re-application of previously learned higher-level regularities to novel input, is a key challenge in cognition. While previous empirical studies investigated human transfer learning in supervised or reinforcement learning for explicit knowledge, it is unknown whether such transfer occurs during naturally more common implicit and unsupervised learning and if so, how it is […]
Jellinek, S. & Fiser, J. (2024) Neural correlates tracking different aspects of the emerging representation of novel visual categories. Cerebral Cortex, 2024 (1), pp. bhad544
Current studies investigating electroencephalogram correlates associated with categorization of sensory stimuli (P300 event-related potential, alpha event-related desynchronization, theta event-related synchronization) typically use an oddball paradigm with few, familiar, highly distinct stimuli providing limited insight about the aspects of categorization (e.g., difficulty, membership, uncertainty) that the correlates are linked to. Using a more complex task, we […]

Perceptual learning is the process by which experience alters how incoming sensory information is processed by the brain to give rise to behavior—it is critical for how humans educate children, train experts, treat diseases, and promote health and well-being throughout the lifespan. Knowledge of perceptual learning requires basic and applied research in humans and nonhuman […]
Fiser J. & Garami L. (2023) Modality-independent biases in temporal processing. Journal of Vision 23 (9), 5430-5430 [Abstract]
The brain encodes dynamic sensory information along different modalities effectively and accurately into structured representations by relying on various biases of different complexities. While the ultimate representation is multimodal, the biases used for encoding have been defined at the level of individual modalities despite a growing body of evidence showing that integration is already present […]
Garber D. & Fiser J. (2023) The effect of consolidation and explicitness on learning and transferring higher-level structural knowledge in vision. Journal of Vision 23 (9), 5308-5308 [Abstract]
While studies on visual statistical learning focus on how specific chunks based on co-occurrence of observable elements are learned, they typically neglect exploring the role of knowledge about the higher-level structure of these chunks in learning. We studied this role of structural knowledge by investigating how first being exposed to only horizontal or vertical shape-pairs […]
Magas D. & Fiser J. (2023) Probabilistic encoding and well-calibratedness of long-term episodic memory. VSS 2023, Journal of Vision 23 (9), 5325-5325 [Abstract]
Accumulating behavioral and neural evidence suggests that incoming sensory input is represented and combined with generalized semantic knowledge in a fundamentally probabilistic way during perceptual processes. Recently we provided evidence that human perceptual decision making is fully probabilistic (encodes uncertainty of all internal variables) rather than task-dependently probabilistic (encoding uncertainty only at the level of […]

What is the link between eye movements and sensory learning? Although some theories have argued for an automatic interaction between what we know and where we look that continuously modulates human information gathering behavior during both implicit and explicit learning, there exists limited experimental evidence supporting such an ongoing interplay. To address this issue, we […]

We analyze multiunit recordings from linear arrays of 16 electrodes spanning 3 or 9 mm in awake ferret V1, as in Fiser et al. Nature 431:573 (2004). Recordings were made at ages ranging from 29 to 168 days postnatal. Fiser et al. 2004 found that activity from P30 to P90 was dominated by similar activity […]
