سرعة التعرف البصري على الحروف العربية إستنادا إلى الخصائص المميزة لنمطها الإدراكي : دراسة تجريبية
The purpose of this study was to determine the relative speed of recognition of Arabic letters and Arabic non-words recognition. Distinguishing features of letters studied were the presence or absence of dots on letters, the number of dots, and the position of dots (above or below the letter). The way the letter is written was also studied i.e. whether it is connected or disconnected to another letter. Letter patterns were also studied relative to their position to the line (on, above, or below the line). Participants were composed of (120) male and female Jordanian university students who volunteered for this study. Participants were divided into three groups i.e. (60) male and female students for each experiment. Non-words composed of four letters were exposed on a lap-top screen for a duration of (50) milliseconds. Exposure was repeated until S's were able to read the non-word. Word stimuli were composed of (40) minimum pairs in the 1st experiment, (26) in the 2nd experiment. Speed of recognition was measured by the number of exposures required to read the non-words correctly. Results indicated that letters without dots were the easiest to recognize. One and two dotted letters were recognized faster than three dotted letters. Letters with dots below were easier to recognize than letters with dots above. Separate letters were recognized more quickly than connected letters, letters written above the line or below were recognized more easily than letters written on the line. (Published abstract)
