Stimuli and Sets
The app shows configurable sets of target stimuli. Each set has many configurable aspects: the trial endpoint, and the group of target or stimuli numbers that will be shown as trials in the set. After each set of trials, an option to continue to the next set is displayed for the experimenter, so that the number of sets can be adjusted for each child, based on either a predetermined design or on the child's performance. All aspects of the tests can also be pre-configured via iTunes.
The stimuli sets provided as app defaults increase in endpoint size, complexity and number of trials. These sets of default target stimuli were created to cover the full range of development: from the pre-kindergarten children (endpoints of 10) to older grades five and six students (endpoints of 100). Each set of stimuli can be modified to meet the experimenter's needs. The app randomly shuffles the target stimuli at the start of each set to randomize the display order of the trials. The end-points of the number lines for each set have default values of 10, 20, 100 and 100.
The app can be configured with many testing sequences. This can allow preparation for multiple ages of subjects, different languages of subjects, different types of tests and many other uses that can meet your testing needs.
