Memory for spatial location in retarded and nonretarded persons.
Item memory and memory for spatial location were examined in college students, mildly retarded persons and moderately retarded persons. They performed under semantic or nonsemantic encoding instructions to remember pictures presented in a large book. Recall and relocation (unexpected) tests followed immediately after studying the pictures and, again, 24 h later. Mildly retarded persons were deficient in memory for items (effortful processing), but not in memory for location (automatic processing). Moderately retarded persons were deficient in both types of memory. Additionally, there were IQ-related differences in the long-term memory of location information, as well as item information. Location memory, as opposed to item memory, was shown to be (1) sensitive to encoding instruction, (2) insensitive to differences in intelligence, and (3) more sensitive to long-term forgetfulness.
