(Skill Area) Skill	Example of situations and questions or tasks
(M)Visual discrimination	Objects are shown in front of the camera, with some shown more than once. Task: Detect which objects were shown multiple times.
(M) Change detection	The camera is filming a table, then looks away for a few seconds, then looks back at the table. Some changes may have occurred. Task: Explain what changed.
(M) Sequencing	Objects are put in a backpack. Task: List their order.
(M) Event recall	A person indicates a region on the table with the hand, then puts objects inside and outside the region. Task: List the objects put inside the region.
(A) Object, action & event counting	A person turns a lamp on and off. Task: Count the number of times the illumination changed in the scene.
(A) Feature matching	A person puts wooden letters on the table. Task: Which letters have the same colour?
(A) Pattern discovery	Geometric shapes are shown in a pattern. Task: What shape will be shown next?
(A) Pattern breaking	A person puts multiple cups all facing upwards and one facing downwards. Task: Indicate the object that breaks the pattern.
(P) Object permanence	A person plays a cups-game with 3-4 cups by hiding a small object under one of the cups, then shuffles the cups. Task: Predict where is the hidden object after shuffling.
(P) Spatial relations & containment	A person puts a bookmark in a book, then puts the same or another book in a backpack. Task: Where is the bookmark at the end?
(P) Object attributes	A person writes on a piece of paper. Task: Is the paper lined or plain?
(P) Motion & occluded interactions	A person moves an occluder object in front of a small object, sometimes moving also the small (occluded) object. Task: Was the small object moved?
(P) Solidity & collisions	A person launches objects against a blocker object, sometimes removing the blocker. Task: Does the object fall off the table?
(P) Conservation	A person pours an equal amount of water in 2 identical glasses, then pours all or part of the water from one glass in a taller or wider glass. Task: How much water is in the last glass?
(P) Stability	A person puts objects on top of each other in a stable or unstable configuration. Task: Predict if the configuration will be stable after placing the last object.
(S) Distractor actions & objects	A person makes tea, and does also some distractor actions unrelated to making tea, e.g. rotating a knife. Task: Identify the distractor action(s).
(S) Task completion & adversarial actions	A person ties shoe laces, but sometimes pretends to tie, or ties the lace of one shoe to the lace of the other shoe. Task: Detect if the action is done correctly.
(S) Object & part recognition	A person conceals a small object in one of their hands, then shuffles the hands. Task: Identify in which hand is the object held.
(S) Action & sound recognition	All scripts. Task: Detect the actions and sounds in the video from a pre-defined list.
(S) Place recognition	All scripts. Task: Detect where is the action taking place.
(S) State recognition	A person uses an electric device. Task: Indicate if the device is on.
(S) General knowledge & Language	Some objects are shown to the camera, some multiple times. Task: Given a list of arbitrary statements or word puzzles, some requiring general knowledge to solve, select the statement that contains a reference to the second distinct object shown.
