BACKGROUND INFO
___________________________________________________________________________________________________________________
This script implements a variant of the Cued Recall Procedure. The Cued Recall Procedure was
introduced by Tolan & Tehan (1999) and was designed to study proactive interference effects on word retrieval.
The Inquisit script implements a variant of the design described in Friedman & Miyake (2004).

TASK DESCRIPTION
___________________________________________________________________________________________________________________
Participants view either one or two blocks of four words each and must retrieve the word from the most recent
block that belongs to a cued category.
___________________________________________________________________________________________________________________
DURATION
___________________________________________________________________________________________________________________
the default set-up of the script takes appr. 20 minutes to complete
___________________________________________________________________________________________________________________
DATA FILE INFORMATION
___________________________________________________________________________________________________________________
The default data stored in the data files are:
(1) Raw data file: 'cuedrecallprocedure_raw*.iqdat' (a separate file for each participant)*
build: The specific Inquisit version used (the 'build') that was run
computer.platform: the platform the script was run on (win/mac/ios/android)
date, time: date and time script was run
subject, group: with the current subject/groupnumber
session: with the current session id
blockcode, blocknum: the name and number of the current block (built-in Inquisit variable)
trialcode, trialnum: the name and number of the currently recorded trial (built-in Inquisit variable)
Note: trialnum is a built-in Inquisit variable; it counts all trials run; even those
that do not store data to the data file.
trialCount: custom trial counter (1-36)
trialCategory: 0 = practice trials
1 = 2block_target (runs foil word in block1; target word in block2)
2 = 2block_control (runs no foil words)
3 = 1block
(Note: the trials are run in a fixed order (that was determined randomly). To
change the order to a complete randomized order, go to 'list.testtrials' and follow instructions)
target: stores the selected target word for the current trial sequence
(target word = the word that needs to be entered into the textbox)
targetCategory: stores the category of the selected target word
foil: stores the foil word (if applicable for '2block_target' trials; otherwise empty)
Foil words come from the same category as the target words and are
presented during the first block in '2block' trials.
Foils are stronger representatives of the target category than the targets themselves
Example: category bird; target = penguin, foil = robin
foilBlockWords: stores the 4 words presented during the 'foil' block
Notes:
- the foil block contains non-target words:
=> it's the first block of 4 words for '2block' trials
=> no foil block for '1block' trials
- the words are stored in the order they appeared
targetBlockWords: stores the 4 words presented during the 'target' block
Notes:
- the target block contains the target word;
=> it's the second block of 4 words for '2block' trials
=> it's the only/first block for '1block' trials
- the words are stored in the order they appeared
2digitNumber: the 2digit number presented during distractor trial
response: the participant's response
distractor trial:
scancode of response button
31=S
38=L
recall trial:
the entered word as it was typed
recallResponse: the recall response in lower case letters only
correct: accuracy of response: 1 = correct response; 0 = otherwise
distractor trials:
1 = the presented number was correctly categorized
0 = otherwise
recall trial:
1 = the entered word was the target word
0 = otherwise
Note: it is recommended to manually check the responses as
spelling errors will be noted as '0'
latency: the response latency (in ms); measured from: onset of trial
recallRT: the duration (in ms) that it took participant to enter the recallSolution
(2) Summary data file: 'cuedrecallprocedure_summary*.iqdat' (a separate file for each participant)*
inquisit.version: Inquisit version run
computer.platform: the platform the script was run on (win/mac/ios/android)
startDate: date script was run
startTime: time script was started
subjectid: assigned subject id number
groupid: assigned group id number
sessionid: assigned session id number
elapsedTime: time it took to run script (in ms); measured from onset to offset of script
completed: 0 = script was not completed (prematurely aborted);
1 = script was completed (all conditions run)
Recall Performance:
propCorrect_overall: overall proportion correct recall (across all test trials)
meanCorrRT_overall: overall mean response time (in ms) of submitting correct recall response (across all test trials)
propCorrect_2block_target: proportion correct recall in 2block-foil/target condition
meanCorrRT_2block_target: mean response time (in ms) of submitting correct recall response in 2block-foil/target condition
propCorrect_2block_control: proportion correct recall in 2block-control condition (no foil is run)
meanCorrRT_2block_control: mean response time (in ms) of submitting correct recall response in 2block-control condition
propCorrect_1block: proportion correct recall in 1block-control condition
meanCorrRT_1block: mean response time (in ms) of submitting correct recall response in 1block-control condition
DistractorTask Performance:
propCorrect_DistractorTask_overall: overall proportion correct magnitude judgments (across all test trials)
meanCorrRT_DistractorTask_overall: overall mean response (in ms) of making correct magnitude judgments (across all test trials)
propCorrect_DistractorTask_2block_target: proportion correct magnitude judgments in 2block-foil/target condition
meanCorrRT_DistractorTask_2block_target: mean response (in ms) of making correct magnitude judgments in 2block-foil/target condition
propCorrect_DistractorTask_2block_control: proportion correct magnitude judgments in 2block-control condition
meanCorrRT_DistractorTask_2block_control: mean response (in ms) of making correct magnitude judgments in 2block-control condition
propCorrect_DistractorTask_1block: proportion correct magnitude judgments in 1block-control condition
meanCorrRT_DistractorTask_1block: mean response (in ms) of making correct magnitude judgments in 1block-control condition

EXPERIMENTAL SET-UP
___________________________________________________________________________________________________________________
(1) DEMO
2 demo trials to explain the procedure:
- 1block
- 2block (fixed sequence)
The demo trials provide more time to the participants for instructions, the distractor task
as well as the recall trials.
(2) TEST
1 test block of 36 trials (12 trials per 3 trialtypes): by default the order of the trials is fixed
(one random sequence has been determined a-priori, see list.testtrials)
General trial set-up:
-> get ready (2000ms)
-> instructions (aloud/silent) (1000ms)
-> block1 words (each of the 4 words is presented for 1000ms) -> 'foil' block
(word1 -> word2 -> word3 -> word4)
-> instructions (aloud/silent) (1000ms)
-> block2 words (each of the 4 words is presented for 1000ms) -> 'target' block
(word1 -> word2 -> word3 -> word4)
-> 8 distractor trials (magnitude trials; each 2 digit number is presented for 1000ms)
(number1 -> number2 -> number3 -> number4 -> number5 -> number6 -> number7 -> number8)
-> cued recall trial (presents target category; time limit = 5000ms)
(a) 12 '2block-target' trials:
- presents 2 blocks of 4 words:
- first block is referred to as the 'foil' block in this script; it contains the foil word
that is matched to the randomly selected target (they come from the same category),
the remaining three words are randomly selected filler words
(order of 4 words is randomly determined)
- second block is referred to as the 'target' block in this script; it contains
the randomly selected target word; the remaining three words are randomly selected
filler words
(order of 4 words is randomly determined)
- 'aloud' instructions are given to the first block (foil block);
'silent' instructions are given to second block (target block)
(b) 12 '2block-control' trials: same as above but instead of a foil word, a fourth filler word
is selected for the 'foil' block
(c) 12 '1block' trials:
- presents 1 block of words ('target block')
- all four words are randomly selected filler words
- order of words is randomly determined
- 'aloud' instructions are given to the block
Notes:
- no word is ever repeated in this experiment. Categories are only repeated for foil and target words.
- the target words/target categories are randomly selected for each trial.

STIMULI
___________________________________________________________________________________________________________________
provided by Millisecond Software - can be edited under section Editable Stimuli
36 Target/Foil Categories: selected from
McEvoy, C. L., & Nelson, D. L. (1982). Category name and instance norms for 106 categories of various sizes.
American Journal of Psychology, 95, 581-634.
Nairne, J. S. (1990). A feature model of immediate memory. Memory and Cognition, 18, 251-269.
Note: Foil words were always the words with a higher correlation with the target category compared to the
target words themselves.
Remaining filler words were taken from the above article as well as from everyday life.
Constraints: Filler words should never overlap with any of the selected target categories.
All words can easily be replaced under section Editable Stimuli.
