Christensen JH., Bex PJ. & Fiser J. (2015) Prior implicit knowledge shapes human threshold for orientation noise. Journal of vision 15 (9), 24-24
Although orientation coding in the human visual system has been researched with simple stimuli, little is known about how orientation information is represented while viewing complex images. We show that, similar to findings with simple Gabor textures, the visual system involuntarily discounts orientation noise in a wide range of natural images, and that this discounting […]
Fiser J. & Aslin RN. (2005) Encoding multielement scenes: statistical learning of visual feature hierarchies. Journal of Experimental Psychology: General 134 (4), 521
The authors investigated how human adults encode and remember parts of multielement scenes composed of recursively embedded visual shape combinations. The authors found that shape combinations that are parts of larger configurations are less well remembered than shape combinations of the same kind that are not embedded. Combined with basic echanisms of statistical learning, this […]
Lengyel G., Nagy M., & Fiser J. (2021) Statistically defined visual chunks engage object-based attention. Nature communications 12 (1), pp. 1-12
Although objects are the fundamental units of our representation interpreting the environment around us, it is still not clear how we handle and organize the incoming sensory information to form object representations. By utilizing previously well-documented advantages of within-object over across-object information processing, here we test whether learning involuntarily consistent visual statistical properties of stimuli […]
Nemeth D., Janacsek K. & Fiser J. (2013) Age-dependent and coordinated shift in performance between implicit and explicit skill learning. Frontiers in computational neuroscience 7, 147
It has been reported recently that while general sequence learning across ages conforms to the typical inverted-U shape pattern, with best performance in early adulthood, surprisingly, the basic ability of picking up in an implicit manner triplets that occur with high vs. low probability in the sequence is best before 12 years of age and […]
Fiser J., Chiu C. & Weliky M. (2004) Small modulations of ongoing cortical dynamics by sensory input during natural vision, Nature 2004 Sep 30; 431:573-578.
During vision, it is believed that neural activity in the primary visual cortex is predominantly driven by sensory input from the environment. However, visual cortical neurons respond to repeated presentations of the same stimulus with a high degree of variability. Although this variability has been considered to be noise owing to random spontaneous activity within […]

The ability of developing complex internal representations of the environment is considered a crucial antecedent to the emergence of humans’ higher cognitive functions. Yet it is an open question whether there is any fundamental difference in how humans and other good visual learner species naturally encode aspects of novel visual scenes. Using the same modified […]

Fiser J., Bex PJ. & Makous W. (2003) Contrast conservation in human vision. Vision Research 43 (25), 2637-2648
Visual experience, which is defined by brief saccadic sampling of complex scenes at high contrast, has typically been studied with static gratings at threshold contrast. To investigate how suprathreshold visual processing is related to threshold vision, we tested the temporal integration of contrast in the presence of large, sudden changes in the stimuli such occur […]

What is the link between eye movements and sensory learning? Although some theories have argued for a permanent and automatic interaction between what we know and where we look, which continuously modulates human information- gathering behavior during both implicit and explicit learning, there exist surprisingly little evidence supporting such an ongoing interaction. We used a […]
