Cognition encompasses all the fundamental mental processes that enable humans to make sense of the information they receive from their environment. Functions such as perception, attention, memory, problem solving, and decision making are the building blocks of the cognitive system. These processes determine the nature of an individual’s interaction with the world and underlie behavior. Memory is one of the most complex components of this structure because it not only stores information but also has a dynamic process that reorganizes information each time it is retrieved. This reconstructive nature of memory sometimes leads to error-prone results.
False Memories As A Cognitive Phenomenon
In this context, false memories are one of the most striking phenomena in memory science. A false memory is defined as the formation of a vivid representation in memory of an event that did not occur, or the recollection of a real event in a different way than it actually happened (Loftus, 2005). In other words, individuals interpret the information produced by their own memory as a record of the outside world and can speak about this information with great certainty. The striking aspect of false memories is not only that they are errors of recall, but also that individuals have a high level of confidence in these erroneous memories.
There are many examples of the formation of false memories from everyday life, legal proceedings, and clinical settings. For example, after hearing a misguided question about the moment of an event, it is quite likely that a witness will believe they saw a detail that did not actually exist. In therapeutic processes, some memories about the client’s past can be shaped through the therapist’s explanations or questions. Furthermore, memories related to childhood may change when recalled in adulthood due to the influence of interpretation and meaning-making processes. These examples show that memory is not merely a structure that stores information, but a system that is constantly reorganized through internal meaning-making processes.
Cognitive Mechanisms Underlying False Memories
Several cognitive mechanisms play a role in the emergence of false memories. First, memory often organizes information at the level of meaning rather than encoding it in detail. This leads to the general framework of an event being preserved while details become vague and gaps are automatically filled in over time. Additionally, association-based functioning causes related concepts to activate together in the mind. Thus, the mental re-enactment of an event or word can cause other representations associated with it, but not actually experienced, to become mixed into memory.
Errors in source monitoring processes also contribute to the formation of false memories; an individual may misinterpret the source of a thought, fantasy, or inference and evaluate it as a real experience. These mechanisms illustrate how memory errors are not random, but systematic outcomes of normal cognitive functioning.
The Deese–Roediger–McDermott (DRM) Paradigm
Experimental methods are needed to understand these cognitive mechanisms. The DRM Paradigm (Deese–Roediger–McDermott) is the most frequently used method in psychology for the controlled study of false memories (Deese, 1959; Roediger & McDermott, 1995). The DRM is based on presenting participants with lists of related words and then asking them to recall these words. The lists contain words that evoke a distinct theme, while the critical word at the center of this theme is deliberately omitted from the list.
For example, when a list consisting of words such as “pillow, bed, night, rest” is presented, a significant portion of participants report seeing the word “sleep,” which does not appear on the list at all. This false recall is a direct indicator of a false memory in experimental terms.
Why Is The DRM Paradigm So Powerful?
The DRM paradigm has gained a strong foothold in the literature due to several important reasons for its preference in false memory research. First, this method allows for the systematic production of false memories, providing reproducible findings in adults, adolescents, and different cultural samples. Second, DRM clearly demonstrates how suggestive processes and memory tracking mechanisms are prone to error. This makes it possible to test under which conditions false memories are more likely to occur.
Third, the method provides a suitable framework for evaluating the effects of variables such as arousal, attention, emotional state, or cognitive load on false memories. In this respect, DRM is considered one of the paradigms with the highest measurement power in cognitive psychology.
Cultural Validity And Research Findings
Studies conducted in Turkey also show that DRM is a valid measurement tool. Research using Turkish word lists has revealed that culturally adapted stimuli also produce a similarly strong false memory effect (Yüvrük et al., 2019). These findings are important in that they show that false memories can occur in every age group as a natural part of memory functioning, not just under specific conditions.
Conclusion
In conclusion, false memories are a striking demonstration of the fallibility of cognitive processes. The reconstructive nature of memory, automatic associations, and source tracking errors pave the way for the formation of false memories. The DRM paradigm is one of the most powerful tools that allows this process to be measured experimentally.
False memory research is critical in many areas beyond being merely an academic field of interest, ranging from education to law, clinical practice to social life. Knowing that memory does not always reflect reality increases individual awareness and contributes to the more reliable execution of social processes.
