The BD-rates, which provide the relative coding
gain between two methods based on the average difference between their RD-curves, are commonly measured for objective quality evaluation by adopting HM as the anchor and utilizing quantization parameters of 22, 27, 32, and 37.
In relative coding of position the items are coded with reference to both the start and end of a sequence and therefore named as start-end model (Henson 1999).
Six items were selected for temporal coding of position, eighteen items comprising three lists were selected for absolute coding of position, and for relative coding of position two lists of five items were selected.
* In relative coding of position two lists were shown each having five items.
In the present research 3x3 factorial design was used having two independent variables each with three levels .The first independent variable was serial learning with its three manipulated levels i.e, temporal, absolute and Relative coding of positions.
Normal group performed better on relative coding of position, supporting the earlier study conducted by Henson (1998).While both experimental and control group remained sensitive to temporal model which is based on clock analogy of Oscillators-based Associative recall (OSCAR) model and required active exercise of cognitive functioning.
