BACKGROUND INFO
___________________________________________________________________________________________________________________
This script implements the Adaptive Composite Complex Span Test (ACCES); an adaptive test of working memory
with visuospatial ("symmetry span test"), mathematical ("operation span test") and verbal subtests
("reading span test").
The ACCES was developed by Gonthier et al (2018). According to the authors "the test presents a fixed number
of trials to all participants, allows for partial credit scoring, and can be used with children regardless
of ability level. The ACCES demonstrated satisfying psychometric properties in a sample of 268 children
aged 8–13 years." (p.910)
All materials for the ACCES – including the stimuli, an open source implementation
of the task script under PsychoPy (Peirce, 2007), and all validation data – can be accessed via the Open Science
Framework platform at https://osf.io/bk7pm/.

TASK DESCRIPTION
___________________________________________________________________________________________________________________
Participants work on 6 reading span test trials. Levels for each trial (after the first) are adapted
based on performance.
Reading Span Test: a dual task involving the evaluation of simple sentences while
also recalling a sequence of digits for a later recall test:
Evaluation of Sentence -> Digit Learning -> Evaluation of Sentence -> Digit Learning.....-> Digit Recall
The number of 'sentence-evaluations/digit learning' combos depends on the level of difficulty (=span size)
of the current test trial. All participants start at level 4. Depending on performance they move up,
stay on the same level, or go down a level. The lowest level tested is level 2; the highest level tested
is level 8.
The task provides 3 practice session before the actual 6 test trials are run:
Practice 1: training of the digit recall task
Practice 2: training of the sentence evaluation task
Practice 3: dual training of the combined task

___________________________________________________________________________________________________________________
EXPERIMENTAL SET-UP
___________________________________________________________________________________________________________________
Note: level = span size
4 phases:
PHASE 1: Practice 1 -Digit Recall Training ("Memory Task")
Participants work on 2 trials (level 2, followed by level 3) with a fixed set of stimuli for each round.
During this phase, they only work on the digit recall task (no sentences are presented)
Trial Sequence:
blank (700ms)->Start Fixation Cross (presented for 1200ms) -> blank (for 500ms) ->
Digit (800ms) -> Blank (800ms) -> Digit (800ms) -> Blank (800ms) -> .......-> Blank (700ms)
-> Recall Screen (as long as needed, corrections possible) -> Feedback (3000ms)
At the end of Practice1, recall performance is analyzed and the practice block is repeated
IF mean recall performance is under 70% correct.
(recall performance: the number of digits correctly recalled in the exact position of presentation)
PHASE 2: Practice 2 - Sentence Evaluation Training ("Processing Task")
Participants work on 10 sentences (e.g. "Fish live on land") and evaluate them to be 'true' or 'false'.
The sentences are the same for each participant and are presented in fixed order.
No digit recall task is run.
Trial Sequence:
blank (700ms)->Start Fixation Cross (presented for 1200ms) -> blank (for 500ms) ->
Sentence (max. 8000ms) -> Feedback (3000ms) -> Blank (150ms) -> Sentence (max. 8000ms) -> Feedback (3000ms)....
At the end of this practice round, evaluation performance is analyzed and the practice block is repeated
if the proportion correctly evaluated sentences is under 70% correct.
Furthermore, the duration of the sentence presentation for the test trials is calculated:
median time (in ms) the problems were answered + 2.5 x Median Absolute Deviation (MAD).
(Range: 2000ms - 8000ms)
PHASE 3: Practice 3 - Dual Task Training
Participants work on 2 combined trials (level 2, level 3). The stimuli are the same for all participants
and are presented in fixed order.
Trial Sequence:
blank (700ms)->Start Fixation Cross (presented for 1200ms) -> blank (for 500ms) ->
Sentence (calculated presentation time during practice 2) -> Blank (150ms) ->
Digit (800ms) -> Blank (800ms) ->
Sentence (calculated presentation time during practice 2) -> Blank (150ms) ->
Digit (800ms) -> Blank (800ms) -> .....
Digit (800ms) -> Blank (700ms) -> Recall Screen
At the end of this practice round, performance is analyzed and feedback is provided.
PHASE 4: Test (Dual Task)
Participants work on 6 combined trials (starting level = 4; levels are adjusted based on performance
thereafter). Each trial (1-6) presents the stimuli from the same stimuli lists in the same order
(though not all participants will work on all the possible stimuli of a particular trial as this is
level dependent). No more feedback is provided.
Trial Sequence:
blank (700ms)->Start Fixation Cross (presented for 1200ms) -> blank (for 500ms) ->
Sentence (calculated presentation time during practice 2) -> Blank (150ms) ->
Digit (800ms) -> Blank (800ms) ->
Sentence (calculated presentation time during practice 2) -> Blank (150ms) ->
Digit (800ms) -> Blank (800ms) -> .....
Digit (800ms) -> Blank (700ms) -> Recall Screen
During each round, the computer calculates
a. processing task performance (here: sentence evaluation performance)
b. recall performance
- the number of correctly recalled digits
- the total number of correctly recalled digits
At the end of each round, the next level is determined based on recall performance:
1. levels goes down by 1 for recall performance less than 60%
2. levels stay the same for 60% <= recall performance < 100%
3. levels go up by 1 for perfect recall performance (100% correct)

TASK DESCRIPTION
___________________________________________________________________________________________________________________
Participants work on 6 symmetry span test trials. Levels for each trial (after the first) are adapted
based on performance.
Symmetry Span Test: a dual task involving the evaluation of simple symmetry problems while
also trying to remember spatial location in a 4x4 matrix:
Evaluation of Symmetry Problem -> Matrix Position Learning -> .....-> Matrix Positions Recall
The number of 'symmetry-evaluations/spatial position learning' combos depends on the level of difficulty
(=span size) of the current test trial. All participants start at level 4. Depending on performance
they move up, stay on the same level, or go down a level. The lowest level tested is level 2;
the highest level tested in the SSPAN is level 7.
The task provides 3 practice session before the actual 6 test trials are run:
Practice 1: training of the spatial location recall task
Practice 2: training of the symmetry evaluation task
Practice 3: dual training of the combined task

___________________________________________________________________________________________________________________
EXPERIMENTAL SET-UP
___________________________________________________________________________________________________________________
Note: level = span size
4 phases:
PHASE 1: Practice 1 -Matrix position Recall Training ("Memory Task")
Participants work on 2 trials (level 2, followed by level 3) with a fixed set of stimuli for each round.
During this phase, they only work on the Matrix position Recall task (no symmetry problems are presented)
Trial Sequence:
blank (700ms)->Start Fixation Cross (presented for 1200ms) -> blank (for 500ms) ->
Matrix position (800ms) -> Blank (800ms) -> Matrix position (800ms) -> Blank (800ms) -> .......-> Blank (700ms)
-> Recall Screen (as long as needed, corrections possible) -> Feedback (3000ms)
At the end of Practice1, recall performance is analyzed and the practice block is repeated
IF mean recall performance is under 70% correct.
(recall performance: the number of Matrix positions correctly recalled in the exact position of presentation)
PHASE 2: Practice 2 - Symmetry Problem Evaluation Training ("Processing Task")
Participants work on 10 Symmetry Problems and evaluate them to be 'true' (when symmetric) or 'false' (when asymmetric).
The Symmetry Problems are the same for each participant and are presented in fixed order.
No Matrix position Recall task is run.
Trial Sequence:
blank (700ms)->Start Fixation Cross (presented for 1200ms) -> blank (for 500ms) ->
Symmetry Problem (max. 8000ms) -> Feedback (3000ms) -> Blank (150ms) -> Symmetry Problem (max. 8000ms) -> Feedback (3000ms)....
At the end of this practice round, symmetry performance is analyzed and the practice block is repeated
if the proportion correctly evaluated Symmetry Problems is under 70% correct.
Furthermore, the duration of the symmetry problem presentation for the test trials is calculated:
median time (in ms) the problems were answered + 2.5 x Median Absolute Deviation (MAD).
(Range: 2000ms - 8000ms)
PHASE 3: Practice 3 - Dual Task Training
Participants work on 2 combined trials (level 2, level 3). The stimuli are the same for all participants
and are presented in fixed order.
Trial Sequence:
blank (700ms)->Start Fixation Cross (presented for 1200ms) -> blank (for 500ms) ->
Symmetry Problem (calculated presentation time during practice 2) -> Blank (150ms) ->
Matrix position (800ms) -> Blank (800ms) ->
Symmetry Problem (calculated presentation time during practice 2) -> Blank (150ms) ->
Matrix position (800ms) -> Blank (800ms) -> .....
Matrix position (800ms) -> Blank (700ms) -> Recall Screen
At the end of this practice round, performance is analyzed and feedback is provided.
PHASE 4: Test (Dual Task)
Participants work on 6 combined trials (starting level = 3; levels are adjusted based on performance
thereafter). Each trial (1-6) presents the stimuli from the same stimuli lists in the same order
(though not all participants will work on all the possible stimuli of a particular trial as this is
level dependent). No more feedback is provided.
Trial Sequence:
blank (700ms)->Start Fixation Cross (presented for 1200ms) -> blank (for 500ms) ->
Symmetry Problem (calculated presentation time during practice 2) -> Blank (150ms) ->
Matrix position (800ms) -> Blank (800ms) ->
Symmetry Problem (calculated presentation time during practice 2) -> Blank (150ms) ->
Matrix position (800ms) -> Blank (800ms) -> .....
Matrix position (800ms) -> Blank (700ms) -> Recall Screen
During each round, the computer calculates
a. processing task performance (here: symmetry performance)
b. recall performance
- the number of correctly recalled Matrix positions
- the total number of correctly recalled Matrix positions
At the end of each round, the next level is determined based on recall performance:
1. levels goes down by 1 for recall performance less than 60%
2. levels stay the same for 60% <= recall performance < 100%
3. levels go up by 1 for perfect recall performance (100% correct)

EXPERIMENTAL SET-UP
___________________________________________________________________________________________________________________
Note: level = span size
4 phases:
PHASE 1: Practice 1 -Letter Recall Training ("Memory Task")
Participants work on 2 trials (level 2, followed by level 3) with a fixed set of stimuli for each round.
During this phase, they only work on the letter recall task (no math problems are presented)
Trial Sequence:
blank (700ms)->Start Fixation Cross (presented for 1200ms) -> blank (for 500ms) ->
Letter (800ms) -> Blank (800ms) -> Letter (800ms) -> Blank (800ms) -> .......-> Blank (700ms)
-> Recall Screen (as long as needed, corrections possible)
-> Feedback (3000ms)
At the end of Practice1, recall performance is analyzed and the practice block is repeated
IF mean recall performance is under 70% correct.
(recall performance: the number of letters correctly recalled in the exact position of presentation)
PHASE 2: Practice 2 - Math Statement Evaluation Training ("Processing Task")
Participants work on 10 math statements (e.g. "2 + 2 = 6") and evaluate them to be 'true' or 'false'.
The math statements are the same for each participant and are presented in fixed order.
No letter recall task is run.
Trial Sequence:
blank (700ms)->Start Fixation Cross (presented for 1200ms) -> blank (for 500ms) ->
Math Statement (max. 8000ms) -> Feedback (3000ms) -> Blank (150ms) -> Math Statement (max. 8000ms) -> Feedback (3000ms)....
At the end of this practice round, evaluation performance is analyzed and the practice block is repeated
if the proportion correctly evaluated math statements is under 70% correct.
Furthermore, the duration of the math problem presentation for the test trials is calculated:
median time (in ms) the problems were answered + 2.5 x Median Absolute Deviation (MAD).
(Range: 2000ms - 8000ms)
PHASE 3: Practice 3 - Dual Task Training
Participants work on 2 combined trials (level 2, level 3). The stimuli are the same for all participants
and are presented in fixed order.
Trial Sequence:
blank (700ms)->Start Fixation Cross (presented for 1200ms) -> blank (for 500ms) ->
Math Statement (calculated presentation time during practice 2) -> Blank (150ms) ->
Letter (800ms) -> Blank (800ms) ->
Math Statement (calculated presentation time during practice 2) -> Blank (150ms) ->
Letter (800ms) -> Blank (800ms) -> .....
Letter (800ms) -> Blank (700ms) -> Recall Screen -> Summary Feedback (3000ms)
PHASE 4: Test (Dual Task)
Participants work on 6 combined trials (starting level = 4; levels are adjusted based on performance
thereafter). Each trial (1-6) presents the stimuli from the same stimuli lists in the same order
(though not all participants will work on all the possible stimuli of a particular trial as this is
level dependent). No more feedback is provided.
Trial Sequence:
blank (700ms)->Start Fixation Cross (presented for 1200ms) -> blank (for 500ms) ->
Math Statement (calculated presentation time during practice 2) -> Blank (150ms) ->
Letter (800ms) -> Blank (800ms) ->
Math Statement (calculated presentation time during practice 2) -> Blank (150ms) ->
Letter (800ms) -> Blank (800ms) -> .....
Letter (800ms) -> Blank (700ms) -> Recall Screen
During each round, the computer calculates
a. processing task performance (here: math performance)
b. recall performance
- the number of correctly recalled letters
- the total number of correctly recalled letters
At the end of each round, the next level is determined based on recall performance:
1. levels goes down by 1 for recall performance less than 60%
2. levels stay the same for 60% <= recall performance < 100%
3. levels go up by 1 for perfect recall performance (100% correct)

BACKGROUND INFO
___________________________________________________________________________________________________________________
This script is run as a final data saving script for the acces.iqjs, Millisecond Software's implementation of
the Adaptive Composite Complex Span Test (ACCES); an adaptive test of working memory
with visuospatial ("symmetry span test"), mathematical ("operation span test") and verbal subtests
("reading span test").
The ACCES was developed by Gonthier et al (2018). According to the authors "the test presents a fixed number
of trials to all participants, allows for partial credit scoring, and can be used with children regardless
of ability level. The ACCES demonstrated satisfying psychometric properties in a sample of 268 children
aged 8–13 years." (p.910)
All materials for the ACCES – including the stimuli, an open source implementation
of the task script under PsychoPy (Peirce, 2007), and all validation data – can be accessed via the Open Science
Framework platform at https://osf.io/bk7pm/.
