THE FLICKER RESPONSE CONTOUR FOR THE ISOPOD ASELLUS
The flicker response contour for the isopod Asellus is a simple probability integral (F - log I) over the whole determinable range (F = 1 to 51). This contrasts with the "distorted" asymmetricalExpand

ON CRITICAL FREQUENCY AND CRITICAL ILLUMINATION FOR RESPONSE TO FLICKERED LIGHT
The curve of mean critical flicker frequency as a function of illumination has been determined for the reaction of the sunfish Lepomis to flicker. It exhibits expected quantitative disagreements withExpand

CRITICAL ILLUMINATION AND FLICKER FREQUENCY, AS A FUNCTION OF FLASH DURATION: FOR THE SUNFISH
From the relations between critical illumination in a flash (Im) and the flash frequency (F) for response of the sunfish to visual flicker when the proportion of light time to dark time (tL/tD) in aExpand

THRESHOLD INTENSITY OF ILLUMINATION AND FLICKER FREQUENCY FOR THE EYE OF THE SUN-FISH
The sun-fish Lepomis responds to a moving system of stripes by a motion of its body. By changing the velocity of motion of the stripe system different flicker frequencies can be produced and thus theExpand

INTENSITY AND CRITICAL FREQUENCY FOR VISUAL FLICKER
Using the rotating striped cylinder device previously employed for determination of the flicker response function with lower animals, corresponding measurements have been made with human observers.Expand

THE FLICKER RESPONSE FUNCTION FOR THE TURTLE PSEUDEMYS
1. At constant temperature, with a fixed proportion of light time in a flash cycle (namely, tL/tD = 1), the mean critical intensity for motor response to visual flicker by the turtle PseudemysExpand

REACTIONS OF LIMULUS TO ILLUMINATED FIELDS OF DIFFERENT AREA AND FLICKER FREQUENCY
In phototropic tests with young Limulus, the phototropic reactions to flickering fields were studied. If the two fields are equal in area and brightness but different in flicker frequency, the numberExpand

TEMPERATURE AND CRITICAL ILLUMINATION FOR REACTION TO FLICKERING LIGHT
The curve connecting mean critical illumination (Im) and flicker frequency (F) for response of the sunfish Lepomis (Enneacanthus gloriosus) to flicker is systematically displaced toward lowerExpand

CRITICAL ILLUMINATION AND CRITICAL FREQUENCY FOR RESPONSE TO FLICKERED LIGHT, IN DRAGONFLY LARVAE
Curves relating flicker frequency (F) to mean critical illumination (Im) for threshold response to flickered light, with equal durations of light and no light intervals, and relating illumination (I)Expand

CRITICAL INTENSITY AND FLASH DURATION FOR RESPONSE TO FLICKER: WITH ANAX LARVAE
Determinations of the flicker response curve (F – log Im) with larvae of Anax junius (dragonfly) for various ratios tL/tD of light time to dark time in a flash cycle provide relations between tL/tDExpand
