MTurk Worker Annotations

We now show the responses from five crowdworkers used to annotate this class-feature pair as core or spurious. Workers first denote if the focus of the image is on the main object (core), or a separate or background object (spurious). They also mark their confidence on a scale of 1 to 5, and provide written explanations for their annotation.

Separate Object	5	The focus of the red region in the highlighted visual attributes is on the keyboard is not a part of a desk.
Main Object	5	The focus is on structures's whole body
Separate Object	4	Focus seems to be on computer peripherals like keyboards, monitors etc. amplified photos seem to back this up.
Main Object	5	The main object is a desk. the focus of the red region on the highlighted visual attributes is on the desk's structure, showing its main parts. because of that, i choose that focus is on some part of the main object.
Main Object	5	Heat map suggest the focus is on keyboard
