where V[A.sub.t] is the simplified symbol of VA([I.sub.t]), which is computed in Section 3.1, BRt denotes the general region (namely, nonattention
region), V[A.sub.t] [union] B[R.subt] = [I.sub.t], and A[R".sub.t] (2v+1, 2y+1) and B[R'.sub.t](2x+1, 2y+1) denote the interpolated pixels in V[A.sub.t] and B[R.sub.t], respectively.
These findings of the present research are not readily explained by extant theories of discrimination learning: response strategy or response pattern theory (Hall, 1973a, 1973b, 1974; Mandler, 1966, 1968; Mandler & Hooper, 1967), selective attention theory (Mackintosh, 1965a), analyzer hierarchy theory (Sutherland & Mackintosh, 1971), and nonattention theory (Anderson, Kemler, & Shepp, 1973).
These findings are in line with the expectation according to selective attention theory (Mackintosh, 1965a) and nonattention theory (Anderson et al., 1973) but not with the expectation according to response strategy or response pattern theories (Hall, 1973a, 1973b, 1974; Mandler, 1966, 1968; Mandler & Hooper, 1967).
But the later compilers of the Prajnaparamita-sutra feared that the paradoxical expression "the recollection of dharmas is a nonrecollection and nonattention
(asmrty-amanasikaro hi dharmanusrmrti[h])" would be misunderstood, and they accordingly added the above explanatory comment in accordance with their own understanding of this passage.
