Ripple effects in memory: judgments of moral blame can distort memory for events.

Can judging an individual as being morally responsible for a negative act affect memory for details of the act? We presented participants with a story describing an individual (Frank) who committed a crime (he walked out on a restaurant bill). Some participants were told that the negative act was not intentional and that Frank was essentially a good person. Others were told that the negative act was intentional and that Frank actually enjoyed it. Control participants were given no extra information. All the participants then judged Frank's moral responsibility for walking out on the bill. When asked a week later to recall information about the event, the participants who had received negative information about Frank remembered that Frank had walked out on a larger restaurant bill than he actually had. Moreover, the degree of memory distortion was predicted by the degree of moral blame that had been attributed to Frank.

Susceptibility to memory distortion: how do we decide it has occurred?

When given suggestive information, some people can be led to believe that they had experiences that they did not actually have. For example, they may come to believe falsely that they got sick eating particular foods as children, and as a result of that belief they may avoid the foods. But how do we know that someone has developed a false belief or memory in this research? The criteria we choose when classifying whether someone has fallen for the suggestion are somewhat arbitrary. We reanalyze our prior data, using different criteria for deciding that a person fell for the suggestion (called a "believer") or did not (called a "non-believer"). Changing criteria obviously affects the percentage of people who are called susceptible and could conceivably affect the conclusions reached about that group. Comparisons between false memories and true memories could differ, too, depending on how memories are defined.

False beliefs about fattening foods can have healthy consequences.

We suggested to 228 subjects in two experiments that, as children, they had had negative experiences with a fattening food. An additional 107 subjects received no such suggestion and served as controls. In Experiment 1, a minority of subjects came to believe that they had felt ill after eating strawberry ice cream as children, and these subjects were more likely to indicate not wanting to eat strawberry ice cream now. In contrast, we were unable to obtain these effects when the critical item was a more commonly eaten treat (chocolate chip cookie). In Experiment 2, we replicated and extended the strawberry ice cream results. Two different ways of processing the false suggestion succeeded in planting the false belief and producing avoidance of the food. These findings show that it is possible to convince people that, as children, they experienced a negative event involving a fattening food and that this false belief results in avoidance of that food in adulthood. More broadly, these results indicate that we can, through suggestion, manipulate nutritional selection and possibly even improve health.

Traumatic memories are not necessarily accurate memories.

Some therapists, as well as other commentators, have suggested that memories of horrific trauma are buried in the subconscious by some special process, such as repression, and are later reliably recovered. We find that the evidence provided to support this claim is flawed. Where, then, might these memory reports come from? We discuss several research paradigms that have shown that various manipulations can be used to implant false memories--including false memories for traumatic events. These false memories can be quite compelling for those who develop them and can include details that make them seem credible to others. The fact that a memory report describes a traumatic event does not ensure that the memory is authentic.

Memory for thematically arousing events.

Many studies have indicated that emotional arousal improves memory for the center, or gist, of an event but undermines memory for the event's periphery. However, all of these studies have elicited emotion by showing participants some salient visual stimulus intended to arouse them (e.g., the sight of a wound). This stimulus may have served as an attention magnet, and this, not the arousal, may have been the cause of the observed narrowing of memory. In this article, we examine how participants remember events that involve thematically induced arousal, arousal produced by empathy, rather than by a visual emotional stimulus. The data show that emotionality improves memory for all aspects of these events, with no memory narrowing.
