Cued vs voluntary task switching is a contrast between two ways of changing mental tasks: in cued switching, an external signal tells you which task to perform next, while in voluntary switching, you decide for yourself when to switch. Cognitive scientists study both because they reveal different parts of how the brain organizes, prepares for, and moves between rules. In a cued version, the stimulus changes — a color appears and you must now name colors, then a shape appears and you must now classify shapes — so the stimulus itself does the switching work. In a voluntary version, the stimulus stream stays the same but the participant presses a button or follows an internal intention to move from one task to the next. Published work, including Gollan, Kleinman, and Wieren's 2014 paper on bilingual language switching, contrasts the two formats and reports that they engage different preparatory processes. A free browser game called the Task Switching Game implements the cued format only, using a fixed thirteen-row route where a visible color-or-shape rule appears on every row.
Defining Cued and Voluntary Task Switching
Both formats ask the same underlying question — how does the mind shift from one rule to another — but they put the switching decision in different hands. In a cued task-switching paradigm, the screen tells the participant which rule applies next, often through a symbol, a word, or a change in the stimulus itself. The participant reacts quickly and correctly to whatever cue appears, and the timing cost of switching is measured by comparing switch trials against repeat trials within the same block. In a voluntary task-switching paradigm, no external rule change occurs; the participant sees the same stimulus stream throughout but at any moment may press a button or follow an internal intention to switch to the other task. The cost of switching is then measured by comparing trials the participant classified as a switch against trials they classified as a repeat, usually with a post-hoc decision record.
The two formats are not interchangeable. Cued switching taxes the ability to reconfigure a task set on the fly when an unexpected rule arrives. Voluntary switching taxes the ability to plan, prepare, and self-initiate a reconfiguration before the next stimulus appears. Researchers often pair the two paradigms in a single study because their switch-cost patterns reveal whether preparation, stimulus-driven reconfiguration, or both drive the observed behavior.
| Dimension | Cued format | Voluntary format |
|---|---|---|
| Who decides the switch | External stimulus or screen cue | The participant's own intention |
| Stimulus stream | Changes to signal the new rule | Stays the same throughout |
| Preparation window | None before the cue appears | Possible before the self-initiated switch |
| Control pathway taxed | Rapid on-line reconfiguration | Planning and intention |
| Typical switch-cost source | Stimulus-driven task-set shift | Intention-triggered reconfiguration |
Why Researchers Compare the Two Formats
The comparison matters because voluntary switches can be prepared in advance, while cued switches cannot. A line of electrophysiology work summarized in the literature shows preparatory reconfiguration before voluntary task switches but not before cued task switches, suggesting that internal intention triggers an early readiness signal that an external cue alone does not. Other work on action-effect associations has compared cued and voluntary switching under conditions where a button press produces a predictable outcome, finding that the learning history of an action modulates voluntary switching more strongly than cued switching. Together these studies argue that voluntary switching is not just a harder version of cued switching — it draws on a partly separate control pathway that benefits from intention and prior experience.
In the bilingual literature, Gollan, Kleinman, and Wieren directly asked which format is easier and reported a voluntary-over-cued advantage for some language-switching conditions, with cued switching imposing a larger on-line cost. The point for a casual reader is straightforward: the cued format isolates fast, reactive control, the voluntary format isolates self-initiated control, and combining both in one study separates the contribution of each.
How the Task Switching Game Uses the Cued Format
The Task Switching Game is built strictly around the cued format. There is no voluntary switching mode, no internal-intention button, and no way to decide for yourself when the rule changes. Instead, the game shows the current rule on screen before every row, and the rule can flip from Colour to Shape or from Shape to Colour only when the fixed route dictates. The rule is always visible, so the task does not ask you to remember an unseen instruction or to infer a secret mapping — the cue is right there in front of you.
Each row displays a single stimulus: an amber circle, a violet circle, an amber square, or a violet square. Under the Colour rule, F means amber and J means violet. Under the Shape rule, F means circle and J means square. You choose the labelled side with a button click, a touch tap, or the F and J keys on a keyboard. Because the rule is visible and the mapping is shown alongside it, every row is a pure cued trial. The browser game records the explicit choice you make for each displayed stimulus and times the visible response interval between row presentation and your first valid input. You can run the full cued route at the Task Switching Game, where the route, the row order, the F and J mapping, and the scoring method are all product-authored browser fixtures you can inspect in plain language.
This game sits in a small family of transparent browser cognitive exercises. A close cousin, the congruent vs incongruent Stroop trials game, explores a different axis of cognitive control — interference within one task rather than switching between two — but uses the same visible-rule, fixed-route philosophy. If you want to feel the voluntary side of the cued-versus-voluntary contrast, you would need a different paradigm entirely; this game does not provide one.
How to Run Through the Thirteen Rows
The route is fixed and short, so a single play-through takes a minute or two. Follow these steps in order:
- Open the page and read the description box. Confirm that the current row's rule is shown above the stimulus — either Colour or Shape — and that the F and J mapping is visible directly below the rule.
- Look at the stimulus in the centre of the row. It will be one of four combinations: amber circle, violet circle, amber square, or violet square.
- Apply the rule. If the rule is Colour, decide whether the stimulus is amber (press F or click the left button) or violet (press J or click the right button). If the rule is Shape, decide whether the stimulus is a circle (press F) or a square (press J).
- Submit exactly one response per row. Repeated key events, clicks that come in after the page moves on, and input after the thirteenth row cannot register a second answer.
- Read the completion panel. It shows accuracy, the average visible response time for the six repeat-rule rows, the average visible response time for the six switch-rule rows, and a switch cost defined as switch average minus repeat average.
| Row position | Role | Counts in averages? |
|---|---|---|
| Row 1 | Starter row, Colour rule | No — no prior rule to repeat or switch from |
| Rows 2–13 (12 rows) | Comparison rows | Yes |
| — 6 of those 12 | Repeat-rule rows (rule matches previous row) | Yes, into repeat average |
| — 6 of those 12 | Switch-rule rows (rule changes from previous) | Yes, into switch average |
| Total | 13 rows, fixed order | — |
The first row is a starter row and is excluded from both averages because it has no preceding rule to repeat or switch from. Twelve comparison rows remain: six repeat the previous rule and six switch from Colour to Shape or from Shape to Colour. That 6-6 balance is built into the route and is disclosed because the completion panel compares only those two groups inside this one game.
What the Summary Numbers Show — and Don't Show
Four numbers appear at the end. Accuracy counts the explicit choices that matched the visible rule. Repeat-rule average is the mean visible response time of the six comparison rows whose rule matched the previous row's rule. Switch-rule average is the mean visible response time of the six comparison rows whose rule changed. Switch cost is switch-rule average minus repeat-rule average.
Switch cost formula
For a single worked example, suppose your repeat-rule average is 850 milliseconds and your switch-rule average is 1100 milliseconds. The switch cost for this attempt is 1100 minus 850, which equals 250 milliseconds. A positive switch cost means switch rows took longer on average than repeat rows on this route; a negative value means the opposite; a value of zero means the two averages matched.
These numbers are summary statistics from one fixed route on your device. They are not a percentile, an attention score, an executive-function diagnosis, a grade, a readiness measure, a benchmark, or a prediction about another task. Screen size, pointer versus touch versus keyboard input, browser timing, interruptions, familiarity with the rule, language, accessibility settings, and ordinary day-to-day variation can all shift one attempt by a wide margin. The summary is reproducible because the route is fixed, but reproducibility of the route does not turn the result into a personal ability measure.
What This Game Does Not Measure
Because the game is purely cued, it cannot tell you anything about voluntary switching. It does not contain a self-initiated switch button, a post-hoc decision record, or a confidence rating. If you want to feel the voluntary side of the contrast, you need a different paradigm.
The game also does not diagnose attention, measure intelligence, show whether your brain has improved, or claim any health, educational, professional, screening, or treatment value. There is no norm table, no clinical cutoff, no population reference, no standardized protocol, and no external benchmark. The shared game shell can retain a best local points total in browser storage, but there is no account requirement, no online leaderboard, and no score sent to any server. A best local total on this private browser fixture is not a clinical or cognitive measure.
The hidden-tab safeguard is also worth describing: if the browser tab becomes hidden during a row, the visible interval pauses, and Resume begins a fresh visible response interval for the same row. This prevents time spent on another app, notification, call, or background tab from being reported as if you were still considering the displayed rule. The safeguard makes the local timer less confusing; it does not make it a controlled or standardized timer. If you need evaluation or support for health, learning, work, or accessibility, an appropriate qualified service is the right route rather than this browser game.
