false events (e.g., getting a rectal enema). A second experiment (Pezdek & Hodge, 1999)
found similar results: Children were significantly less likely to form a false memory for an
implausible false event than for a plausible false event.
The idea that only plausible events can become false memories runs contrary to the
earlier work of Loftus and colleagues and to research concerning some very implausible
false memories that have been successfully implanted, such as a memory for satanic rituals
and alien abductions (Mack, 1994). Loftus and colleagues (Mazzoni et al., 2001) conducted
several experiments in which they found that implausible events could be made more
plausible by having the experimenters provide false feedback to the participants, who read
articles telling of the implausible events as if they had actually happened to other people.
The false feedback involved telling the participants that their responses to a questionnaire
about fears were typical of people who had been through one of the false events (much as
a well-meaning therapist might suggest to a client that certain anxieties and feelings are
typical of someone who has been abused). These manipulations were so successful that
participants not only developed false memories for the events but also even contradicted
their own earlier statements in which they denied having these experiences in childhood.
The researchers concluded that there are two steps that must occur before people will be
likely to interpret their thoughts and fantasies about false events as true memories:
- The event must be made to seem as plausible as possible.
- Individuals are given information that helps them believe that the event could have
happened to them personally.
The personality of the individual reporting such a memory also matters, it seems. In
one study, people who claimed to have been abducted by aliens (an implausible event) were
compared to a control group with no such memories on a measure of false-memory recall
and false recognition. Those who reported recovered memories of alien abduction were far
more likely to recall or recognize items that were false than were the controls (Clancy et al.,
2002). Other variables that predicted a higher false recall and recognition response were sus-
ceptibility to hypnosis, symptoms of depression, and the tendency to exhibit odd behavior
and unusual beliefs (such as past-life regression or the healing ability of crystals).

automatic encoding
recall vs.
recognition
false positives can occur (e.g., eyewitness testimony)
strong emotional associations can lead to vivid and detailed “flashbulb” memories
more cues stored with a piece of information, the easier the retrieval
improved memory for information if physical surroundings
are similar to those when the memory was first formed
improved memory for information if physiological or
psychological state is similar to that when the memory
was first formed

recall: few or no external cues required
recognition: match incoming
sensory information (e.g., see or
hear) to what is already in memory
retrieval failure: (e.g., “tip of the tongue”)
serial position effect: memory improved for items
at beginning (primacy) and end (recency) of a list
constructive
processing
of memories
memories are rarely completely accurate and become less accurate over time
Loftus and others have suggested that memory retrieval is a constructive process;
memories are “built” at time of retrieval

can result from change
