2.0: Colon Syntax

Description

This sample shows you how to use the colon syntax feature. The colon syntax feature will pull multiple items from one List, allowing you to show multiple stimuli from the same List on one Slide.

Abstract

By using the colon syntax feature, E-Prime will pull two items from the same List that is being referenced. This allows the program to display two stimuli at once.
In the TrialList for this sample, there are two columns that represent the stimuli that will be displayed in the following Text Slide marked “Stimulus” and “Stimulus2”. In the column marked Stimulus2, there are a few cells that contain not only an attribute reference, but also a colon and number inside of it. A typical attribute reference (e.g. [StimList]) has a standard value of “:0” which means only one item from the List will be displayed. In this sample however, there are several cells with a “:1” inside the attribute reference (e.g. [StimList:1]). This allows two words to be pulled from the List referenced inside the attribute reference. The nested List, called StimulusList, is where the stimuli that are being referenced are stored. In this sample, the colon syntax feature is used to choose words from a List called StimulusList in order to create dissimilar pairings of words. The word that the colon syntax feature chooses from StimulusList is a random selection from StimulusList. This is because, in the Selection tab of the Property Pages of TrialList, the order is set to Random Selection. Otherwise, if the list were set for Sequential Selection, the colon syntax feature would simply select the next word in the List. This method can be applied to as many samples and stimuli as necessary.
