These two processes are utilized throughout one’s life. In other words, when children learn a new concept, they first evaluate their existing understanding and then alter their expectations to integrate the new information. In assimilation, new information is taken in and integrated into preexisting mental models, whereas in accommodation, the preexisting mental model is adapted and changed in light of the new knowledge. Cognitive ProcessesĪccording to Piaget, children balance assimilation and accommodation when processing knowledge or a new experience. Their responses did not, according to Piaget, show a lack of intelligence due to inexperience, but rather he believed this was due to younger youngsters thinking differently. It occurred to him that younger children’s answers were markedly different from those of older children. Piaget developed an interest in children’s reasoning while working in a Parisian IQ testing facility. More than anything else, Piaget was interested in how children’s cognitive skills changed throughout their lives.
He felt that our capacity for “abstract symbolic reasoning” sets us apart from other species. By examining children’s memory processes, his goal was to document the stages of cognitive growth. Throughout his career, Piaget researched the development of logical reasoning in children. His early work focused on biology and philosophy, and he sought to investigate how an adult developed the ability to reason logically and form accurate judgments from facts. But ultimately, Oeberst hopes that these methods can help relieve the suffering often felt by those who believe in false memories and give them back control over their own story.Jean Piaget (1896 - 1980), a famous Swiss developmental psychologist, was one of the most prominent developmental researchers during the twentieth century. “It is well possible that (false) memories that have been held for longer (and that people are perhaps emotionally invested in) may be more difficult to reverse.”įor such long-held memories, Oeberst suggests that the reversal phase may need to be proportional in length. “There is not much research on the reversibility of distorted memories yet,” says Blank in an email. After following up with participants a year later, these belief levels had dropped even lower to just 5 percent.Įven with the success demonstrated in these trials, Hartmut Blank, co-author on the study and researcher of experimental and social psychology at the University of Portsmouth, said that the question still remains whether such methods could be used to reverse long-held false memories. When participants revisited their memories after experiencing both reversal methods, the researchers reported that belief in their false memories dropped to as low as 15 percent. With false memory sensitization, the researchers explained to participants that false memories can sometimes be created by repeatedly recalling memories-as they had been doing over their three memory interviews.
For source sensitization, a researcher prompted participants to remember that memories may not always be based on our lived experience but could instead come from a family photo album or another person’s narrative. The first reversal method was called “source sensitization” and second “false memory sensitization.”īoth methods relied on simply reminding patients about the unreliability of memory. With the participants thoroughly inoculated to their false memories, the research team then employed two methods to attempt to reverse the process they’d just set into motion. For example, that they had run away in the past or been in a car accident. To attempt to reverse these kinds of experiences in their study, Oeberst and colleagues recruited 52 young adult volunteers and (with the help of their parents) used suggestions to implant several false, yet plausible, memories. taking images from dreams or family narratives as actual recollections of own experiences).” the interviewer/parents/therapists) or even direct source confusions or source misattributions (e.g. In an email, Oeberst said that this “may lead to the retrieval of content without its correct source (e.g.
Part of what makes it so easy for our memories to be confused or fragmented in the first place, explained Aileen Oeberst, professor of psychology at the University of Hagen and first author on the paper, is that the content of a memory and the source of a memory are often stored separately in our minds. For the first time in a realistic setting, this research team showed that it is possible to implant false memories and then reverse them. But there may be hope yet for disentangling real memories from imposters thanks to new research published this month in the journal PNAS by psychologists from the U.K.
