Libraries

PsyScript allows you to make “script libraries collections of handlers
and properties that you can use over again. These are full objects, so you can
create multiple instances in your experiments, for instance to maintain two
parallel adaptive staircases, just make two staircase objects.

If you have suggestions for changing these libraries, or if you make new libraries
yourself, please submit them to me.

Contents

FileHandler: A collection of handlers useful in every
script. This does lists, initializes file paths, randomises items etc.

Staircase: An adaptive staircase object.

Eyelink.lib: Acollection of handlers to help
you write Eyelink applications.

RB.lib: Acouple of handlers created for doing funny things
in terms of creating masks out of single characters and controlling their length
etc.

Using a Library

To use the library load it at the top of your script.

set helper
to load script
file (“”& Psyscript
base folder &” libraries:file.lib”)

Then call the handlers you need using the following three equivalent forms:

libraryName ‘s handler
()

e.g set
newList to
helper’s removeItem
( 3 , {1,2,3,4,5,6})

handler of
libraryName

e.g. set newList
to removeItem
( 3 , {1,2,3,4,5,6})
of helper

tell library
to handlerName
()

e.g. tell helper
to removeItem ( 3
, {1,2,3,4,5,6})
