    Form with simple survey-style questions

  • Stimulus Form

    Survey-style form repeated for each stimulus

  • Label

    Each stimulus is given a description.

Rating & Similarity

  • Multi Arrangement

    The relationship between stimuli, such as their similarity, is indicated by their proximity

  • Drag & Rate

    Stimuli are given a rating and associated confidence, by dragging them to a position

  • Card Sorting

    A category is chosen for each stimulus by placing it in the corresponding zone

  • Triplet Choice

    One of three presented stimuli is chosen as the odd one out

  • Order Sort

  • Match-to-Sample

    Which of two stimuli matches the target

  • Gallery Select

    Stimulus is picked from several displayed

    A category is chosen for each stimulus by placing it in the corresponding circle

  • Preference Elicitation

    Voting among stimulus options

Rapid Serial Visual Presentation

  • Cued Imagery

    One of two stimuli is retro-cued to be imagined, and the vividness rated

  • Timed Keyboard Response

    Presents each stimulus, and records the reaction time of a keyboard response.

  • Attentional Blink

    An RSVP paradigm where an item following another may be masked

  • Visual Search

    Participant selects the target among a number of distractors

Checks & Calibration
