selectionrate attribute

The selectionrate attribute determines how frequently a new item should be selected from the pool.

Member of

<counter> <list>

Syntax

/ selectionrate = rate

Parameters

rate One of the following values:
Value Description
always Select a new item everytime.
trial Select a new item once per trial.
block Select a new item once per block.
experiment Select a new item once per experiment.

Remarks

Consider an example where multiple stimuli share a given counter. This attribute can be used to determine whether the same item is selected for each stimulus on a given trial or block, or whether a new item is selected for each stimulus.

The default setting is 'trial', which selects a single new item on each trial.

Examples

The following counter randomly selects a new item for each stimulus that references it:

<counter>
/ selectionrate = always
/ items = (1, 2, 3, 4, 5)
</counter>
