A cycle-averaged pupillary response balance and a luminance ratio are computed for each presentation of a stimulus pair.

A stimulus pair response curve is computed by fitting cycle-averaged pupillary response balances to a sigmoid function of the luminance ratios.

Create familiarization videos that pair the auditory stimuli with the visual stimuli as appropriate for each condition.

A cycle-averaged pupillary response balance and a luminance ratio are computed for each presentation of a stimulus pair.

A stimulus pair response curve is computed by fitting cycle-averaged pupillary response balances to a sigmoid function of the luminance ratios.

These chosen stimuli make up the test stimuli.

Each pair of lines provides a pair of ports.

Provide caregivers with a pair of blacked-out sunglasses to wear so they cannot see the stimuli.

A first pair of transistors is coupled as a first differential pair, and a second pair of transistors is coupled as a second differential pair.

The black makes a strong and striking combination, careful not to promote an excess of stimuli with the pair.

The plurality of slots include a pair of slots orthogonal to the pair of frame arms and the deflector includes a pair of apertures radially inward of the pair of slots and orthogonal to the pair of frame arms.

At least one of the pairs of conductors comprises a twisted pair.

A second pair of signal sources connected to the second pair of capacitors.

In the pyrrole-imidazole polyamide, a Py/Im pair corresponds to a C-G base pair, an Im/Py pair corresponds to a G-C base pair, and a Py/Py pair corresponds to both an A-T base pair and a T-A base pair.

The stimulus can be heat, vibration, or electrical stimulus, or any combination thereof.
