rightArrow
Experiments
rightArrow sets the text label displayed under a fixed right-pointing arrow image during CFPT sorting trials (test column equal to CFPT). Together with leftArrow it labels the two ends of the sortable stimulus row (for example “most similar” / “least similar”). It is decorative/instructional text, not a response option, and it only has an effect on CFPT trials, whether their stimuli are images or words. On every other trial type the column is ignored.
Syntax
Section titled “Syntax”Type the label you want under the right arrow, for example least similar.
Any free text is accepted, and HTML markup in the cell is rendered as markup.
Dynamic %...% variables are not substituted in this column: they would appear on screen exactly as typed.
Options
Section titled “Options”| Value | Effect |
|---|---|
| any non-empty text (or HTML) | Rendered as the label under the right arrow image on CFPT trials |
| empty cell | No label; the space under the right arrow stays empty. The arrow images still appear |
There are no keywords: whatever you type is shown as text.
Defaults & missing values
Section titled “Defaults & missing values”Leave the column out of the trial file, or leave a cell empty, and no label is drawn under the right arrow. On CFPT trials the arrow image itself still appears, just without text underneath.
Column headers are matched case-insensitively, so rightarrow works too.
Works with
Section titled “Works with”test: only trials set toCFPTshow the arrows. Trials set toCFPT2ignore this column.leftArrow: the label for the other end of the row, shown alongside this one.presTime: sets the CFPT countdown displayed in the top-right corner while the arrows are visible. The arrows disappear when the trial ends.- Position and size are fixed: the arrow image sits in the lower part of the display with its label just underneath, both aligned to the right edge. You cannot move or resize either from the trial file.

Tips & gotchas
Section titled “Tips & gotchas”- No variable substitution:
%response%and similar would display literally. - The arrows appear only on CFPT trials presented on a single screen. A CFPT trial split across several screens never shows them.
