A global initiative bringing together researchers using the same image database to collect and share behavioral and neuroscience data in object recognition and understanding.

How are we able to make sense of the objects around us, recognize them, and act on them in a meaningful way? These are challenging questions that require a concerted effort across disciplines. The THINGS initiative was born out of the idea that we can overcome these challenges by working on a shared set of objects, allowing us to bridge the gap between brain and behavior, recording techniques, species, and artificial intelligence. Many laboratories around the world have started collecting data with THINGS images. Anyone can be part of the initiative.

THINGS concepts and images

Martin Hebart, Adam Dickter, Alexis Kidder, Wan Kwok, Anna Corriveau, Caitlin Van Wicklin, Chris Baker

A freely available database of 26,107 high quality, manually-curated images of 1,854 diverse object concepts, curated systematically from the everyday American English language and using a large-scale web search. Includes 27 high-level categories, semantic embeddings for all concepts, and more metadata.

THINGS similarity

Martin Hebart, Charles Zheng, Francisco Pereira, Chris Baker

More than 4.70 million triplet odd-one-out similarity judgments for 1,854 object images, plus a 66d interpretable embedding. A previous set of 1.46 million triplets served to identify 49 interpretable object dimensions predictive of behavior and similarity (Hebart et al., 2020, Nat Hum Behav).

New THINGS metadata, with 53 high-level categories, typicality ratings, nameability scores for all images, size ratings, and ratings along several dimensions (e.g. animacy, manipulability, valence, arousal, preciousness, etc.). In addition, 1,854 license-free images were collected that can be used and reproduced (e.g. in publications) without any restriction.


Lukas Muttenthaler, Martin Hebart

Streamlines the extraction of neural network activations by providing a simple wrapper for extracting activations from a wide range of commonly used deep convolutional neural network architectures.

THINGS memorability

Max Kramer, Martin Hebart, Chris Baker, Wilma Bainbridge

Memorability scores for all 26,107 object images, collected in a large sample of >13,000 participants. Offers a systematic evaluation of memorability across a wide range of natural object images, object concepts, and high-level categories.

THINGS feature norm

Hannes Hansen, Martin Hebart

Feature production norms for all 1,854 object concepts in THINGS, generated with the natural language model GPT-3, developed by OpenAI.


Hebart Lab, Baker Lab

Event-related functional MRI data in 3 subjects for 8,640 images (720 categories, 12 images per category), collected over the course of 12 sessions. Includes extensive anatomical scans, population receptive field mapping, and functional localizers. Optimized for studying object recognition with a broad and systematic range of object categories.

Event-related functional MRI data at 3T in 8 subjects for 4,320 images (720 categories, 6 images per category, 3 repeats per image), using a memory paradigm. Optimized for the study of object recognition for hypothesis-based analyses, data-driven analyses, and representational similarity analysis.

data collection completed


Baker Lab, Hebart Lab

Magnetoencephalography (MEG) data in 4 subjects for 22,248 images (1,854 categories, 12 images per category), collected over the course of 12 sessions. Optimized for studying object recognition with a broad and systematic range of object categories.

Tijl Grootswagers, Ivy Zhou, Amanda Robinson, Martin Hebart, Thomas Carlson

Electroencephalography responses in 50 subjects for 22,248 images (1,854 concepts, 12 images per category), collected in a single session per participant using an RSVP paradigm.


Alessandro Gifford, Kshitij Dwivedi, Gemma Roig, Radoslaw Cichy

Freie Universität Berlin, Goethe Universität, Frankfurt am Main

Raw and preprocessed EEG recordings of 10 participants, each with 82,160 trials spanning 16,740 image conditions coming from the THINGS database.


Jaan Aru, Kadi Tulver, Tarun Khajuria

A dataset of "constellation" images that can be used to study inference in human vision and AI. The images are stripped of local details creating a dotted outline of the object that can be inferred from the local pattern. The dataset includes 3533 image sets of a total of 1215 common objects from the THINGS dataset. A selected set of 481 top constellation images and the code to generate more constellation images from photos are also included.
