Vision and Computational Cognition

Our research

We are able to recognize objects, people, and places without effort and effectively interact with our visual world. This ability is remarkable, as it requires us to map ever-changing visual input to our knowledge of the regularities of the world and the repertoire of actions we can apply to it. But how is the light that hits our retina transformed into representations that enable us to recognize and interact with our environment? And how can we capture visual representations in a way that takes into account the complexities of the visual world and at the same time gives us an understanding of the regularities and laws that govern our visual system? In the Vision and Computational Cognition Group at the Max Planck Institute for Human Cognitive and Brain Sciences, we aim to answer these fundamental questions, using a combination of research tools from psychology, neuroscience, and computer science.


Our approach

Our research aims at understanding vision from three perspectives. From a data science perspective, we collect and analyze large-scale representative datasets in both human behavior and neuroimaging (functional MRI, magnetoencephalography), allowing us to capture much of the complexity of our visual worlds and identify key characteristics that underlie our mental and neural representations. From a cognitive neuroscience perspective, we link these large-scale datasets to hypothesized representational properties and computational models, and we conduct targeted experiments testing the properties of visual recognition we have identified. From a computational perspective, we apply computational models of vision and semantics (deep neural networks, semantic embeddings), multivariate pattern analysis, and advanced machine learning methods to characterize representations in the human brain and behavior and identify interpretable representations in humans and artificial intelligence. To address longstanding questions about vision and computation in the brain, we develop novel analysis tools for a deeper, more powerful, and more fine-grained analysis of behavioral and neuroimaging data.

This Is Us

As an interdisciplinary team, we are spanning a broad bandwidth of science, from Psychology over Cognitive Neuroscience to Computer Science.

We have three new lab members: Ülkü Tonbuloglu and Carina Daun will be starting as research assistants, and Julia Norman will be starting as an intern and research assistant! Welcome to the VICCo group!

Johannes Roth leaves our lab!

There is another Johannes leaving our lab: Johannes Roth completed his Master's project on creating synthetic stimuli that maximally activate individual voxels in the human visual system. Having completed his Master's, he will continue working in his recently founded startup on data analysis and web development. We wish him all the best for his future!

Johannes Singer leaves our lab!

Johannes Singer completed his Master's project on the representation of object drawings in deep neural networks and has started a PhD in the group of Radek Cichy. We wish him all the best! The good news: We collected MEG and fMRI data and will continue to collaborate on this ongoing project. Yay!

The representation of object drawings and sketches in deep convolutional neural networks

Singer, J., Seeliger, K., & Hebart, M. N.

2020, NeurIPS Workshop SVRHM

Drawings are universal in human culture and serve as tools to efficiently convey meaning with little visual information. Humans are adept at recognizing even highly abstracted drawings of objects, and their visual system has been shown to respond similarly to different object depictions. Yet, the processing of object drawings in deep convolutional neural networks (CNNs) has yielded conflicting results. While …


Revealing the multidimensional mental representations of natural objects underlying human similarity judgements

Hebart, M. N., Zheng, C. Y., Pereira, F., & Baker, C.I.

2020, Nature Human Behaviour

Objects can be characterized according to a vast number of possible criteria (such as animacy, shape, colour and function), but some dimensions are more useful than others for making sense of the objects around us. To identify these core dimensions of object representations, we developed a data-driven computational model of similarity judgements for real-world images of 1,854 objects. The model …


THINGS: A database of 1,854 object concepts and more than 26,000 naturalistic object images

Hebart, M.N., Dickter, A.H., Kidder, A., Kwok, W.Y., Corriveau, A., Van Wicklin, C., & Baker, C.I.

2019, PloS one

In recent years, the use of a large number of object concepts and naturalistic object images has been growing strongly in cognitive neuroscience research. Classical databases of object concepts are based mostly on a manually curated set of concepts. Further, databases of naturalistic object images typically consist of single images of objects cropped from their background, or a large number …
