However, it may in practice buy sildenafil online australia be difficult to distinguish between differences in neural activity related to variable task difficulty and differences due to the resultant increased retrieval monitoring, or retrieval orientation, discussed below. Then, the effects of retrieval effort on the processing of retrieval cues could be distinguished from fluctuations due to various products of retrieval associated with different response types during postretrieval processing. Another approach would be to contrast conditions of varying difficulty separately for different response types (i.e., hits, misses, correct rejections, and false alarms). It may be hard buy sildenafil online australia to assess the level of difficulty of a retrieval effort elicited by a particular retrieval cue, however. Behavioral measures such as response latencies and accuracy rates may provide estimates for degree of difficulty of the retrieval task.
Retrieval Orientation A third and final proposed preretrieval process, retrieval orientation (Johnson, 1990. Rugg & Wilding, 1996), refers to “the specific form of the processing that is applied to a retrieval cue” (Rugg & Wilding, 1999, p.
