Summary 1. Differences in phenomenal shape character exercise influence upon the fusion threshold. Phenomenal shape properties are critical factors in the determination of the CFF metric. 2. The relative psychophysical energies of various shapes can be measured by episcotister technique; phenomenal shapes may thereby be graded according to their relative energy levels, operationally. 3. Production of optimal gamma-motion is useful, in conjunction with CFF determinations, in the investigation of the relative psychophysical energies of phenomenal shapes. 4. There is an intimate relation between gamma-motion and fusion; gamma and CFF are in one and the same line of psychophysical development. 5. The experimental evidence strongly points to the factor of apparent figural equilibrium (unstable, stable, or neutral) as being of critical significance in connection with CFF and optimum gamma-motion. 6. It may not properly be asked, ‘For a visual stimulus, what is the minimum time interval between successive flashes at which succession is recognizable?’ Rather, the question should be framed thus: ‘What is the minimum time interval between successive flashes of a specific phenomenal shape at which succession is recognizable?’ 7. Phenomenal shape, Gestalt, is not an “Undverbindung” (something “additive”, an “and-combination”), but possesses autonomy as a functional entity and constitutes a psychophysical field force.
