The present systems and methods provide a mechanism to assess viewer behavior, features of stimuli, and the interaction between viewer behavior and stimuli. The systems and methods described herein for quantifying blink response and blink inhibition provide moment-by-moments measurements of viewer engagement by measuring what is or is not engaging enough to warrant viewers' inhibition of blinking. The present disclosure describes measures of visual scanning, eye movements, blink data, and blink timing data to derive a measure of how engaged a person is with what he or she is looking at. Blink-related data as a measure of viewer engagement provides a mechanism for determining the most engaging spatial and temporal aspects of a stimulus.

1. A method for displaying visual engagement over time of a plurality of individuals with respect to a dynamic visual stimulus, comprising the steps of: receiving blink data indicative of blink responses to the dynamic visual stimulus for each of the plurality of individuals;retrieving, via software executing on a processor, control blink data from a database, wherein the control blink data comprises at least one randomized pattern of blinking associated with each of the plurality of individuals;comparing, via software executing on the processor, the received blink data to the control blink data to identify one or more differences between the received blink data and the control blink data; andgenerating, via software executing on the processor, a display of the one or more differences between the received blink data and the control blink data. 2. The method of claim 1, wherein the blink data for each of the plurality of individuals corresponds to a rate of change for each individual's pupil size. 3. The method of claim 1, wherein the blink data for each of the plurality of individuals corresponds to eyelid closure. 4. The method of claim 1, further comprising the step of converting, via software executing on the processor, the blink data to binary format for comparison purposes. 5. The method of claim 1, further comprising the step of aggregating, via software executing on the processor, the blink data for the plurality of individuals. 6. The method of claim 1, wherein the control blink data further comprises an average blink rate for the plurality of individuals when no dynamic visual stimulus is present. 7. The method of claim 1, wherein the control blink data further comprises an average blink rate for a group of individuals different from the plurality of individuals when no dynamic visual stimulus is present. 8. The method of claim 1, wherein the control blink data further comprises a probability distribution of average blink rates for the plurality of individuals as obtained by permuting the blink data of the plurality of individuals. 9. The method of claim 8, wherein the step of permuting the data of the plurality of individuals comprises circular shifting with respect to an original timing of blink data collection. 10. The method of claim 8, wherein the step of permuting the data of the plurality of individuals comprises randomizing an order of blinks and inter-blink intervals for each individual. 11. The method of claim 1, wherein the one or more differences between the received blink data and the control blink data comprise one or more of the following: increased blink rate as compared to the control blink data, decreased blink rate as compared to the control blink data, lack of blinks within a predetermined time period, exceeding a predetermined number of blinks within a predetermined time period. 12. The method of claim 1, wherein the one or more differences between the received blink data and the control blink data is a marker of a developmental, cognitive, or mental disorder. 13. The method of claim 12, further comprising the step of using the display of the one or more differences between the received blink data and the control blink data in connection with a diagnosis of an individual. 14. The method of claim 1, further comprising the steps of: synchronizing, via software executing on the processor, the received blink data with the dynamic visual stimulus; andgenerating, via software executing on the processor, a display of the one or more differences between the received blink data and the control blink data in connection with the dynamic visual stimulus. 15. A system for displaying visual engagement over time of a plurality of individuals with respect to a dynamic visual stimulus, comprising: a processor;software executing on the processor for receiving blink data indicative of blink responses to the dynamic visual stimulus for each of the plurality of individuals;software executing on the processor for retrieving control blink data from a database, wherein the control blink data comprises at least one randomized pattern of blinking associated with each of the plurality of individuals;software executing on the processor for comparing the received blink data to the control blink data to identify one or more differences between the received blink data and the control blink data; andsoftware executing on the processor for generating a display of the one or more differences between the received blink data and the control blink data. 16. The system of claim 15, wherein the blink data for each of the plurality of individuals corresponds to a rate of change for each individual's pupil size. 17. The system of claim 15, wherein the blink data for each of the plurality of individuals corresponds to eyelid closure. 18. The system of claim 15, further comprising software executing on the processor for converting the blink data to binary format for comparison purposes. 19. The system of claim 15, further comprising software executing on the processor for aggregating the blink data for the plurality of individuals. 20. The system of claim 15, wherein the control blink data further comprises an average blink rate for the plurality of individuals when no dynamic visual stimulus is present. 21. The system of claim 15, wherein the control blink data further comprises an average blink rate for a group of individuals different from the plurality of individuals when no dynamic visual stimulus is present. 22. The system of claim 15, wherein the control blink data further comprises a probability distribution of average blink rates for the plurality of individuals as obtained by permuting the blink data of the plurality of individuals. 23. The system of claim 22, wherein the step of permuting the data of the plurality of individuals comprises circular shifting with respect to an original timing of blink data collection. 24. The system of claim 22, wherein the step of permuting the data of the plurality of individuals comprises randomizing an order of blinks and inter-blink intervals for each individual. 25. The system of claim 15, wherein the one or more differences between the received blink data and the control blink data comprise one or more of the following: increased blink rate as compared to the control blink data, decreased blink rate as compared to the control blink data, lack of blinks within a predetermined time period, exceeding a predetermined number of blinks within a predetermined time period. 26. The system of claim 15, wherein the one or more differences between the received blink data and the control blink data is a marker of a developmental, cognitive, or mental disorder. 27. The system of claim 26, further comprising software executing on the processor for using the display of the one or more differences between the received blink data and the control blink data in connection with a diagnosis of an individual. 28. The system of claim 15, further comprising: software executing on the processor for synchronizing the received blink data with the dynamic visual stimulus; andsoftware executing on the processor for generating a display of the one or more differences between the received blink data and the control blink data in connection with the dynamic visual stimulus.
