An accidental view of an object is where:

We interpret a 3D object as a 3D one when it is partially occluded.

We interpret a 3D object as a 2D one because we can only see one face, which is an improbable view.

We interpret a 2D object as a 3D one by inferring the information we cannot see directly.

We interpret a 2D object as a 3D one because it is unlikely to be anything else.

A cube is seen behind another rounder object that partially occludes it. This is best explained because:

It exhibits good continuation

It generates T-junctions at a common edge in the image

It has a different colour

It has straight edges, and these edges are in plain view

A researcher wishes to investigate the effectiveness of a new, promising treatment versus the standard treatment. However, they preferentially recruit more severe cases to trial the new treatment. This is a form of:

Selection sampling bias

Allocation bias

100%

Maturation bias

Attrition bias
