## Dataset Overview
- 34 participants, each with 1 session

---

## Experimental Design
The EEG experiment used a stimulus set of 242 images (121 “challenge” and 121 “control” images) derived from comparisons between human behavioural performance and AlexNet.

- **Main task:** Each trial consisted of a single image presented for 200 ms followed by a 100 ms blank. Trials were grouped into sequences of 14 images. At the end of each sequence, participants reported whether a paper clip appeared anywhere in that sequence.

## Derivatives
The derivatives/ folder contains outputs from the decoding analyses, including time-resolved decoding accuracy matrices for object identity.
