Templates
Pre-configured study templates across all seven paradigms. Start in 30 seconds, customize from there.
Blind Taste Test
Compare food or beverage samples without brand bias. Balanced presentation order and cleansing protocols.
Design A/B Test
Split-test two design variants with random assignment. Measure preference, usability, or conversion.
Stroop Task
Classic interference paradigm. Measure reaction time to congruent vs. incongruent color-word stimuli.
Portfolio Ranking
Blind ranking of creative works. ELO-based scoring eliminates order and position bias.
Likert Scale Survey
Structured attitude measurement with randomized item order and reverse-coded items.
Sensory Threshold
Adaptive staircase method to estimate perceptual thresholds with precision.
Vignette Study
Scenario-based judgement study. Pinned scenario + multiple items per vignette with optional AI-generated illustrations and narration.
Simon task
Classic spatial-compatibility RT task. Stimulus side vs response side; the Simon effect = incompatible − compatible mean RT.
Colour match-to-sample
Winawer-style categorical colour perception. CIE Lab swatches at fixed L*, uniform ΔE between adjacent stimuli, within- vs cross-category trials.
Color Phi illusion
Two alternating coloured dots at controlled ISI. Below threshold you see one dot moving; above it, two dots flickering. Adaptive staircase finds each participant’s threshold ISI.
Reverse-phi motion
Contrast-inverting dots produce perceived motion opposite to physical displacement. Same renderer as Color Phi, with contrast polarity flipped.
Müller-Lyer illusion
Adjust the variable line until it matches the reference. Illusion magnitude = adjustable − reference (px). Classic length-illusion paradigm.
Ebbinghaus illusion
Adjust the central circle to match the reference. Surrounding satellite size biases perceived central size.
Ponzo illusion
Two converging depth lines bias perceived length. Adjust the “far” line to match the “near” one.
Vertical-horizontal illusion
Adjust the horizontal line to match the vertical reference. Vertical lines are perceived as longer than physically equal horizontal lines.
Lexical decision
Classic RT task: distinguish real words from non-words. Reveals semantic priming and word-frequency effects.
Flanker task
Eriksen flanker: identify a central target surrounded by compatible/incompatible flankers. Measures conflict resolution.
Go / no-go
Respond to Go trials, withhold on no-go. Measures response inhibition and prepotent-response control.
Implicit association (IAT-lite)
Categorize stimuli with shared vs conflicting response mappings. Classic measure of implicit associations.
Moral dilemma vignette
Trolley-problem family. Two versions manipulate means/side-effects; participants rate acceptability on a Likert scale.
Hiring scenario vignette
Between-subjects hiring decision with manipulated applicant cues. Reveals implicit bias and norm anchoring.
Clinical judgement vignette
Patient case with manipulated symptom framing. Clinicians rate likelihood of diagnosis / treatment on Likert.
Wine tasting ranking
Blind pairwise ranking of wine samples — labels hidden, positions randomized. Produces an ELO-ranked leaderboard.
Packaging preference A/B
Between-subjects split on packaging variants. Measures purchase intent + perceived quality with attention check.
Logo concept A/B
Present two logo concepts between subjects. Measures memorability, fit-to-brand, and aesthetic rating.
ESM mood diary
Daily experience-sampling diary. 3-6 prompts/day across 2 weeks. PWA push + email by default; participants can swap to Telegram or WhatsApp.
ESM stress + affect
Random-window experience-sampling for stress + PANAS-short affect. Configure prompt windows + channel preferences in the Schedule step.
MTurk-ready Stroop
Classic Stroop wired for MTurk. Server-side completion code mints on the thank-you page after attention checks pass.
Prolific-ready Likert
Likert-scale instrument wired for Prolific. PANEL_PER_SESSION completion codes; redirect URL pre-formatted with cc= query string.
Bakker-ready vignette
Scenario-judgement study wired for Bakker recruitment. PANEL_JWT completion code with the panel participant ID embedded.
