Number sequences will be displayed on the screen.
A number sequence is a list of numbers that are linked by a rule. If you work out the rule, you can work out the next numbers in the sequences.
In some tasks, the numeric value of the digit is crucial, while in some the context where the digit is located is crucial.
Pay attention to the position of the "?" because it is not always at the end of a series of numbers.
The Progress bar will show how many items are left until the end of the task.
Since demo mode is enabled, solutions to all tasks will be available.
Application settings:
Number of items:The number of stimuli in the task
Stimulus generator type:DefaultPseudorandomStimuli will be generated in the default type.
There are 56 basic types of items (stimuli). Items are always generated by pseudo-random numbers according to a certain set of rules. After 56 stimuli, 55 item types are repeated with (new) pseudo-random numbers.
Timer is enabledNo
Total task time (seconds):00:10:00
Enable backward - display the button for the previous item:Yes
Answer is not required - display the button for the next item:Answer to each item is not required.
Keyboard: if you allow scrolling through items (backward or forward), you can use the ENTER or Page Down keys to go forward, and the Page Up key to go back.
Progress bar shows:ItemsTimeNothing
Table format at the end of the task:SummarizeDetailsTable containing summarized results for: number of correct answers, number of errors and number of missing values
Show solution of each task (demo):No
Legend:
a[n] = member of a numeric sequence at position n (n = 1,2,3,..)
Dyad = two members of a numerical sequence one after the other. a[n], a[n+1],..
Triad = three members of a numerical sequence one after the other. a[n], a[n+1], a[n+2],..
Tetrad = four members of a numerical sequence one after the other. a[n], a[n+1], a[n+2], a[n+3],..
c = const = constant
Note: As all items are generated by random numbers, in a very small percentage of cases it is possible to create a random combination of numbers that will create a new logical rule (new solution). In that case the same item will have multiple solutions and such new solutions will not be properly evaluated by this application. Although the use of complex arithmetic operations (+, -, *, /) with large numbers (eg 3-digit) was avoided, in rare cases, due to the use of random numbers, this could not be avoided.
