A01. Human Vision and Psychophysics

Five connected studies move human vision and psychophysics from direct observation and explanation through controlled experiment, application and critique. Five active studies connect evidence, experiment, application and critique.

Observe → Understand → Experiment → Apply → Critique and record

• Detection Thresholds

  Begin Human Vision and Psychophysics with detection thresholds: observe directly and record the conditions before interpreting the result.

• Contrast Sensitivity

  Within Human Vision and Psychophysics, build a working explanation of contrast sensitivity, keeping the model distinct from the appearance it describes.

• Adaptation

  In Human Vision and Psychophysics, test adaptation by changing one controlled variable and comparing the evidence.

• Observer Variation

  Apply observer variation within Human Vision and Psychophysics to a practical color decision, preserving both the reasoning and its constraints.

• Controlled Perception Experiment

  In Human Vision and Psychophysics, critique controlled perception experiment against evidence, exceptions and failure conditions before carrying it forward.
