test

Experiments Surveys & forms The CFPT sorting modes apply to experiment trials only; on other rows the value is a plain label echoed to the results.

test is a labeling column for the results file. Nothing groups, filters or orders trials by it. Its only behavioral role is as a mode switch: the exact values CFPT and CFPT2 put the trial into the drag and drop sorting task instead of the standard test display. Use it as a free form experiment or task label for analysis, and use CFPT/CFPT2 only when you actually want the sorting paradigm.

Syntax

Type any label you like, for example the name of the task or experiment. It is saved with your results and changes nothing about the trial.

Two values are special: CFPT and CFPT2 switch the trial to the drag and drop sorting task. The whole cell must be exactly one of those two words, spelled with capitals; every other value is just a label.

Options

Value	Effect
CFPT	Shows the drag and drop sorting task instead of the standard image or word display. When the trial is advanced, the final sort order (; separated stim ids) is recorded as the response and the summed positional error score is recorded in the correct column. Button 1 is pinned to top: 85%. A countdown timer turns red under 10 s and shows “Time up!” then disables sorting when it expires. Trial text is positioned relative to the sorting area. The presTime driven hide of screen 1 is skipped.
CFPT2	Shows the second sorting display and is excluded from the standard test display.
any other string	Pure metadata, copied into the results row.
empty	No effect.

Defaults & missing values

An absent column or a blank cell leaves the trial as a normal trial, since neither matches the sorting task values.

The test column only appears in the results file when it is present in your trial file.

Works with

• type must be test for a CFPT trial to be saved; on any other trial type nothing is recorded.
• stim1..N and sort1..N: the sorting task reads the sort columns, and the standard image or word display is bypassed on CFPT and CFPT2 rows.
• button1 is repositioned on CFPT trials.
• Results: the cell value is copied into the test column of the results file for every saved trial.

Examples

test	subtest	type	trialNo	stimFormat	stim1	stim2	key
stroop	block1	test	1	word	RED;GREEN		1

test is a plain label saved with the results.

test	type	stimFormat	target	stim1	sort1	sort2
CFPT	test	.jpg	face_target	face_a	3	1

test=CFPT switches the trial to the face sorting task; the final sort order is saved as the response and the positional error score is saved in the correct column.

Tips & gotchas

• The column name itself is matched case insensitively, but cell values are kept exactly as you wrote them apart from trimming.
• A presTime on a CFPT2 row still hides the first screen when it elapses; on a CFPT row it does not.
• Older documentation called this the “primary experiment identifier”, but nothing groups, filters or orders trials by it. It is a label, plus the sorting-task switch.

Caution

The sorting task values are case sensitive: cfpt or Cfpt do not trigger it, only CFPT and CFPT2 do.
