Memory Revision Notes

What is Reconstructive Memory?

The reconstructive memory theory posits that memory is an active process of piecing together stored information, rather than a passive retrieval of exact records. Each time a memory is recalled, it is reconstructed based on fragments of information, previous knowledge, expectations, and personal biases. This implies that memory is not fixed and can be altered or distorted during retrieval. Unlike a video recording, memory is more like an ongoing story that we update and embellish, sometimes incorporating information that wasn't originally present.

The Role of Schemas

Schemas are mental frameworks or organised packets of information about objects, events, or people, developed through experience. According to the reconstructive memory theory, schemas play a crucial role in how we perceive, store, and recall information. When we recall an event, our schemas help us fill in missing details or make sense of ambiguous information, often leading to 'remembering' things that fit our expectations rather than what actually happened. For example, a 'classroom' schema might lead someone to recall seeing a chalkboard, even if there wasn't one, because chalkboards are typical of classrooms.

How Memory Can Be Distorted (Elizabeth Loftus)

Elizabeth Loftus's research is central to understanding reconstructive memory, particularly her work on eyewitness testimony. She demonstrated that memories can be easily influenced by post-event information, such as leading questions. For instance, in her car crash experiments, participants who were asked about cars 'smashing' into each other estimated higher speeds and were more likely to report seeing broken glass (even when there wasn't any) compared to those asked about cars 'hitting' each other. This highlights how external factors can distort existing memories or even implant false ones, illustrating the active and vulnerable nature of reconstruction.

Aim and Design of Braun, Ellis and Loftus (2002)

The primary aim of Braun, Ellis and Loftus (2002) was to investigate whether misleading advertisement could create false memories in individuals. Specifically, they wanted to see if exposure to an ad suggesting an encounter with a non-Disney character (Bugs Bunny) or a character outside their usual context (Ariel) at Disneyland would lead people to falsely remember such an event. The study used an experimental design, where different groups of participants were exposed to either a control advertisement or an advertisement containing misleading information about a visit to Disneyland. This allowed for a direct comparison of memory recall between those who received the suggestion and those who did not, helping to establish a cause-and-effect relationship between the misleading information and the formation of false memories.

Methodology and Participants

The methodology involved participants viewing a fictional advertisement for Disneyland. One group saw an ad depicting Bugs Bunny, a Warner Bros. character, at Disneyland, while another group saw an ad with Ariel (a Disney character, but the ad implied an unusual meeting scenario). A control group viewed an ad without these specific misleading elements. After viewing the advertisements, participants were asked questions about their childhood visits to Disneyland, including whether they had shaken hands with Bugs Bunny or met Ariel. The participants were college students, which is a common demographic in psychological research, but also a potential limitation regarding generalisability to other age groups. The use of questionnaires helped to systematically collect data on their reported memories.

Key Findings and Conclusion

The significant finding was that participants exposed to the misleading advertisements were considerably more likely to report having had a false memory of interacting with Bugs Bunny or Ariel at Disneyland. For instance, a notable percentage of those shown the Bugs Bunny ad claimed to have met him at Disneyland. This clearly demonstrated that post-event information, specifically through advertising, can successfully implant false memories. The study concluded that memory is highly reconstructive and susceptible to suggestion. It is not always an accurate recording of past events but can be actively shaped and distorted by information encountered after the event itself. This has important implications for understanding how memory works and its vulnerability to manipulation.

Evaluation of the Study

A strength of this study is its clear experimental design, allowing researchers to control variables and infer cause-and-effect relationships between the misleading ad and false memory creation. The real-world relevance to advertising and eyewitness testimony is also a significant strength. However, a limitation is that the study was conducted in a laboratory setting, which may reduce its ecological validity; remembering meeting a fictional character might differ from remembering a critical real-life event. Also, the participants were college students, meaning the results might not generalise to other populations, such as children or older adults who might have different susceptibility to suggestion. The ethical implications of implanting false memories, even non-traumatic ones, also raise considerations about psychological harm, although participants were debriefed.
