The task involving the most cognitive processes was the rule match task in which subjects had to determine whether the two letters presented both were vowels or not vowels. The physical match task was the most simple; subjects had to encode the letters, compare them to each other, and make a decision.
The task requires the subject to connect 25 consecutive targets on a sheet of paper or a computer screen, in a manner to like that employed in connect-the-dots exercises. There are two parts to the test. In the first, the targets are all the whole numbers from 1 to 25, and the subject must connect them in numerical order.
Mental rotation has been studied to try to figure out how the mind recognizes objects in their environment. Researchers generally call such objects stimuli. Mental rotation is one cognitive function for the person to figure out what the altered object is. Mental rotation can be separated into the following cognitive stages: [2]
Mental folding in tasks usually require a series of mental rotations to sequentially fold the object into a new one. Classic mental folding tests are the Paper folding task which is similar to Origami. Origami also requires mental folding by assessing folding a 2D paper enough times to create a 3D figure. [21] Visual penetrative ability is ...
Visual object recognition refers to the ability to identify the objects in view based on visual input. One important signature of visual object recognition is "object invariance", or the ability to identify objects across changes in the detailed context in which objects are viewed, including changes in illumination, object pose, and background context.
Researchers often use "filtering" tasks to study the role of covert attention of selecting information. These tasks often require participants to observe a number of stimuli, but attend to only one. The current view is that visual covert attention is a mechanism for quickly scanning the field of view for interesting locations.
Mental effort is used while engaging in performing any mental task, [29] and the greater the complexity, the greater the effort needed to solve a task. Kahneman believes there are three basic conditions which needed to be met for proper completion of a task. [ 29 ]
Visual search is a type of perceptual task requiring attention that typically involves an active scan of the visual environment for a particular object or feature (the target) among other objects or features (the distractors). [1] Visual search can take place with or without eye movements.
