SURFACE COLOURATION, LETTERING AND REFERENTIAL DIMENSION OF TRAFFIC MARKER PERCEPTION

FIVE EXPERIMENTAL TRAFFIC MARKERS DIFFERENTIATED WITH RESPECT TO COLORATION AND LETTERING WERE EACH PRESENTED AT 7 ANGLES OF ORIENTATION RANDOMLY REPEATED 5 TIMES. FIVE GROUPS COMPRISING 15 DRIVERS PER GROUP GAVE JUDGMENTS OF SHAPE AND SLANT. IT WAS FOUND THAT SIGNALLING ASPECTS OF THE MARKER (FORM, COLORATION AND LETTERING) PRODUCED SIGNIFICANT DIFFERENCES UPON APPARENT SHAPE. DIFFERENCES IN SLANT PERCEPTION WERE NOT DEPENDENT UPON THE THREE SIGNALLING CHARACTERISTICS. CONSISTENT WITH PRIOR RESEARCH, THE REFERENCE ASPECT OF THE MARKER (ANGLE OF ORIENTATION) PRODUCED LARGE ERRORS OF UNDERESTIMATION PARTICULARLY AT THE MOST ACUTE ANGLES. THE PERCEPTUAL FUNCTIONS SUGGESTED THAT SYSTEMATIC DIFFERENCES SEPARATE PHYSICAL AND PSYCHOLOGICAL SPACES. /AUTHOR/
