• Human subjects position the LO independent of its shape.
• When positioning the LO near to the RO, human subjects are not affected by boundary effects. However if the positioning is to be done far from the RO boundary effects become prominent.
• The way human subjects position the LO depends on size of the RO, boundary effects, scale effects.
• When combining orthogonal prepositions human subjects tend to assign equal weightage to each preposition.
• When asked to position the LO between two RO's human subjects position the LO at the centre of the available space between the two RO's.

• We could not completely show the independence of positioning of the LO w.r.t. orientation of LO.
• We could not draw conclusive results for the effect of size of LO for the positioning. However, the data hints at an effect of size of LO on positioning.

• One question as yet unanswered is whether the centre of a polygon should be defined as the centroid or the mean of its maximum and minimum coordinates. We think that the answer to this question depends on the shape of the polygon and is thus difficult to characterise.
• In case of combination of orthogonal prepositions is the positioning done with respect to the boundary of the RO or the centre of the RO ?
