Square Shape Focus Reaction Test
The Square Shape Focus Drill measures selective attention and response inhibition, the ability to locate a specific target quickly while ignoring distractions. Each gate’s LED display shows a geometric shape in a random colour. The athlete must find and trigger only the gate showing a small filled square. Large squares, hollow squares, other shapes and all colours are distractors and must be ignored. Because the target position and the distractors change every round, the athlete cannot anticipate where to go and must focus strictly on shape. It requires V3 Timing Gates.
Position: Mount the gates upright magnetically to a suitable surface, or lay them flat on the floor facing upward, depending on the space available and the demand you want. Gate placement sets the emphasis of the drill. Close together, the drill tests visual discrimination and response inhibition with minimal movement. Spread further apart, the athlete must scan, turn their head and travel between gates, adding a movement and decision-making demand. Set the athlete up centrally, ready and facing the gates.
Cue: “Each gate shows a shape. Find the small filled square and trigger it as fast as you can. Ignore large squares, hollow squares and every other shape. Ignore the colours completely, they mean nothing. Only the shape matters. Triggering the wrong gate counts as an error. Reset and get ready for the next one straight away.”
Step 1: Position your V3 Timing Gates, either mounted upright magnetically or laid flat on the floor facing upward. Set them close together to emphasise visual discrimination, or spaced further apart to add movement and head turning. Ensure all gates are powered on.
Step 2: Open the app and select the Square Shape Focus Drill.
Step 3: On the Gate Setup screen, tap Scan to connect your gates. Allocate a master gate by pressing the button on the side of that gate. Once allocated, it appears at the top of the Gate Layout list marked as Master, and the remaining gates are numbered in order (2, 3 and so on) as they connect.
Step 4: Confirm the gate order. Use the drag handles beside each gate to reorder them so the numbering matches your physical layout. Use Settings to adjust the drill configuration if required.
Step 5: Tap Start Drill. Position the athlete ready and facing the gates.
Step 6: During the drill, every gate displays a shape in a random colour. One gate shows the small filled square. The athlete triggers that gate as quickly as possible to clear the round. Triggering any other gate is recorded as an error. The shapes, colours and target position then change for the next round. This repeats for the set number of rounds.
Step 7: When the session is complete, review the results screen. The app displays:
- Rounds completed, shown as Session Complete.
- Hits, the number of times the athlete correctly triggered the small filled square.
- Misses, the number of rounds where the athlete failed to trigger the target in time.
- Errors, the number of times the athlete triggered a distractor gate.
- Avg Reaction, the athlete’s average reaction time in milliseconds.
- Reaction Distribution, a bar chart of reaction time (ms) for each round.
- Round Analysis, a round-by-round list of individual reaction times and any errors.
Step 8: After reviewing:
- Tap Save Trial to store the result.
- Tap Redo to retest without saving.
Interpreting the results
Average reaction time gives the headline number. Read it alongside errors. A fast average with multiple errors indicates the athlete is responding before confirming the shape, so the result reflects impulsivity rather than true processing speed. A slow average with zero errors indicates a cautious strategy. The best outcome is fast reactions with few or no errors.
Compare the athlete’s Square Shape Focus reaction time with their Simple Reaction Drill result. The difference between the two shows the time cost of filtering out distractors. A large gap suggests visual discrimination and inhibition, not raw reaction speed, is the limiting factor.
Results are influenced by fatigue, arousal, familiarity with the drill and gate spacing. Compare an athlete to their own baseline across sessions using the same layout, rather than to an external standard. Allow a familiarisation trial before recording data you intend to track.
Using the Square Shape Focus in rehab and performance
In a performance setting, the drill trains the ability to pick out relevant information and ignore everything else. This reflects game situations where athletes must identify a teammate, an opponent or a space among visual clutter, and resist reacting to misleading cues such as dummies, feints or crowd movement. Comparing Simple Reaction, Numbers 1-9 and Square Shape Focus results helps separate raw reaction speed, sequencing ability and selective attention.
In a rehab and return to sport setting, run the drill with close gate spacing early on to train attention and response inhibition while physical load is restricted. As the athlete progresses, widen the spacing to add movement demand. Monitor whether rising physical load or fatigue increases reaction times or errors. Rising errors under fatigue indicate that inhibitory control is degrading before physical output, which is relevant to injury risk, since poor decisions under fatigue often precede poor movement.
