Working Memory- Sternberg Paradigm
Working Memory: Definition
Working memory is the short-term system that temporarily holds and manipulates information for quick mental tasks.

Sternberg Task- Definition:
? In the Sternberg paradigm, the computer first shows participants a short list of items (the memory set).

? After a short delay, a single item (the probe) appears on screen.

? The participant presses one key if the probe was in the memory set (positive probe) and another key if it was not (negative probe).

For tech team's reference:

1. Task Overview
? Main rounds: 15 sets of stimuli presented sequentially.

? Probe Rounds: 30-65 per memory set depending on span and population.

Main Trials (Learning Rounds)-Definition:

? These are the "study" or "learning" rounds of the task.

? In each main trial, participants see a short list (set) of items one after another and are asked to remember them.

? Example: They might see A ? D ? F (for adolescents) or K7 ? C9
? R2 (for adults).

Probe Trials (Testing Rounds)- Definition:

? These are the "testing" rounds that come after each main round.

? Participants are shown single items (probes) one by one and must decide whether the item was in the memory set or not.

? For each probe:

? If it was in the memory set ? Positive probe (press "Yes")

? If it was not in the memory set ? Negative probe (press "No")

Examples:

? Memory set = A, D, F ? Probe = D ? Positive

? Memory set = A, D, F ? Probe = G ? Negative

2. Main Rounds Stimuli
? Adolescents: Letters only (A-Z), memory set sizes = 1, 3, 5 letters, sequential & alternating presentation (1?3?5)

? Adults: Alphanumeric (e.g., K7, C9), memory set sizes = 2, 4, 6 digits, sequential & alternating presentation (2?4?6)
3. Probe Round Numbers by Span
? Adolescents:

? 1-letter ? 30 probe trials

? 3-letter ? 50 probe trials

? 5-letter ? 50 probe trials

? Adults:

? 2-alphanumeric digits ? 30 probe trials

? 4-alphanumeric digits ? 65 probe trials

? 6-alphanumeric digits ? 65 probe trials


4. Rounds Flow
1. The participant first reads the Main Task Instructions.
Adolescents ( 14 to 18):

"Welcome to the Memory Challenge Game! You will see a set of letters appear on the screen one by one. After a short pause, you will be shown a letter and need to decide whether it was part of the set you just saw. If you saw it before, press Yes; if not, press No.Take your time and try to respond as quickly as you can. Don't worry if it seems tricky at first - we'll start with a few practice rounds to get you ready."

Adults ( 18 to 22):

"Welcome to the Memory Challenge Game! You will see sequences of letter-number pairs ( for example: A1, C3) appear on the screen one by one. After a few seconds, you will be shown a series of letter-number pairs and need to decide if it was part of the sequence you just saw. if you saw it before, press Yes; if not, press No. This is just a practice round, so relax and get used to how the game works!"

2. Participants complete practice trials
Practice Task Trial Flow - Adolescents (14-18 years)

? Memory Set Spans: 1-letter

? Presentation: Letters will be presented one by one.
? Trial Steps:

1. Fixation Cross: "+" for 0.3 s

2. Memory Set: Present a 1, letter stimuli for 1.1s

3. Retention Interval: Blank screen for 1 s

4. Probe Display: Centered letter with Yes/No buttons, remains visible until response or time-out each for 6 seconds.

a) Participant Response: Chosen option highlighted in light blue

b) No Response: Display "Time is up!" for 1 s

5. Fixation Cross: "+" for 0.3 s
6. Next :


¦ Repeat steps 4-5 for all probe trials of the current stimuli.

Feedback Rules for practice task:

(a) Correct Response (Probe matches memory set and participant presses correctly):

? Show message: "Correct! You remembered it right."

? Duration: 1 s


(b) Incorrect Response (Pressed wrongly or missed correct probe):

? Show message: "That's okay-try to remember the set carefully."

? Duration: 1.5 s


(c) No Response / Delay Alert:
If no response within the allowed response window (2.5 s for adolescents, 2 s for adults):

? Play soft alert tone

? Show text: "Please press your choice quickly!"

? Duration: 1 s


4. General Feedback Between Practice Blocks

After each practice block (e.g., 10-12 trials):

? If accuracy = 70%:
Show: "Great work! You're getting the hang of it."

? If accuracy < 70%:
Show: "Let's try again! Focus and respond a bit faster."


Duration: 2 s before moving to the next block.

5. After the participant completes all the blocks, we would give instructions that emphasize the end of this task.
Adolescents (14-18 years)

"Awesome work! You've completed this challenge - stay sharp, the next one is coming up!"

Adults (18-22 years)

"Well done! You've successfully finished this task - let's move on to the next part."

5. Implementation Notes
? Each span runs all its probe trials before moving to the next span

? Sequential & Alternating Presentation: Memory set spans alternate throughout the task (1?3?5 or 2?4?6)

? Probe remains visible until response

? Inter-Round Interval (ITI): 300 ms recommended

6. Scoring Instruction Manual for tech team:

Data Columns Required (will not be shown to participants for interpretation):
? Round Number: Sequential number identifying each round.
? Memory Set Size: Number of items in the memory set for that round.

? Probe Item: The item presented for recognition in the round.
? Probe Type: Indicate whether the probe is a Target (included in the memory set) or a Non-Target (not included).
? Participant Response: Indicate whether the participant responds 'Yes' (recognizing the probe as in the memory set) or 'No'.
? Response Accuracy: Score 1 if the participant correctly identifies the probe ("Yes" for Target, "No" for Non-Target), otherwise 0.
? Reaction Time (RT): Time in milliseconds from probe presentation to participant response.

Scoring Instructions:
? When the participant correctly recognizes the probe item as a member (for Targets) or non-member (for Non-Targets), assign a score of 1 (Correct Response).
? When the participant incorrectly responds (e.g., 'Yes' to Non-Target or 'No' to Target), assign a score of 0 (Incorrect Response).
? Record Reaction Time (RT) only for trials where the participant responded.

Additional Scoring Parameters:
? Total Rounds Answered: Count of all probe rounds where participants responded.
? Total Rounds Not Answered: Count of all probe rounds with no response.
? Correct Responses: Sum of all probe rounds with correct response (score = 1).
? Incorrect Responses: Sum of all probe rounds with incorrect response (score = 0).
? Accuracy Rate:
? Accuracy = Correct Responses/ Total Rounds Answered×100.
? Mean Reaction Time: Average RT across all correctly answered rounds.
