More general as well as specific theories explaining false memories are discussed, and we close with implications for practice. For example, hege and dodson 2004 explicitly shifted attention to perceptual details by presenting words in different fonts, thereby promoting an itemspecific processing of list items. In recent years there has been a blast of research on false memories in recalling events that did not happen. These results lead us to expect that positive affect may be functional in tasks where relational encoding is required, as in learning or to generate new ideas, but that negative affect may be functional in tasks requiring itemspecific encoding, as in. In contrast to arndt and reder 2003 and hege and dodson 2004, we presume that the constraint on false memory imposed by the variables we investigate is not due to impoverished relational processing, but instead we propose an explanation in which itemspecific and relational processing work in concert, resulting in distinctive processing that can reduce false memories. Schacter 0 1 0 this research was supported by national institute on aging grant ag08441 and by a grant from the human frontiers science program.

Nonruminative processing reduces overgeneral autobiographical memory retrieval in students. Type of encoding itemspecific or relational was manipulated between subjects in experiment 1 and within subjects in experiment 2. Whether encoding variability facilitates memory is shown to depend on whether itemspecific and relational processing are both performed across study blocks, and whether study items are weakly vs. One possible reason for age differences in false memory susceptibility is that older adults may not encode contextual information that allows them to distinguish between presented and nonpresented but internally activated items.
This generally occurs due to the constructive nature of memory, where a disruption of that process will result in distortion of the memory.

Alternatively, false memories can be reduced when individuals are oriented at retrieval to scrutinize their memory for specific source information or other itemspecific details. Memory based explanations predict reductions in false recognition in both designs, resulting from enhanced recollection of itemspecific details. The procedure typically involves the oral presentation of a list of related words.
