 The modifications carried out in the dataset are thought to evaluate cognitive biases in a few-shot setting and with different task complexities. 
 We make use of 25k instances from the original dataset, while the remaining ones serve as few-shot examples.
 Each instance is prompted with all possible unbalanced 4-shot distributions.
-We increase task complexity by introducing an additional neutral example between the first and last two examples.

+**Dataset Fields:**
+- `idx`: original sentence id, in the format `\<original_partition\>_\<original_id\>.
+- `sentence`: test sentence.
+- `label`: sentiment of the test sentence, either "negative" (`0`) or "positive" (`1`).
+- `dist`: few-shot distribution (`0000`, `1111`, `0001`, `0010`, `0100, `1000`, `1110`, `1101`, `1011, `0111`).
+- `shot\<n\>_idx`: original id of the example sentence, in the format `\<original_partition\>_\<original_id\>.
+- `shot\<n\>_sent`: example sentence.
+- `shot\<n\>_label`: sentiment of the example sentence.
+- `few_shot_string`: string with all 4 shots the sentence is prompted with.
+- `few_shot_hard_string`: string with the same 4 shots and an additional neutral example between the first and last two to increase task complexity.
