Memory conformity: can eyewitnesses influence each other's memories for an event?

The current study investigated memory conformity effects between individuals who witness and then discuss a criminal event, employing a novel procedure whereby each member of a dyad watches a different video of the same event. Each video contained unique items that were thus seen only by one witness. Dyads in one condition were encouraged to discuss the event before each witness (individually) performed a recall test, while in a control condition dyads were not allowed to discuss the event prior to recall. A significant proportion (71%) of witnesses who had discussed the event went on to mistakenly recall items acquired during the discussion. There were no age‐related differences in susceptibility to these memory conformity effects in younger (18–30 years) as compared to older (60–80 years) participants. Possible social and cognitive mechanisms underlying the distortions of memory due to conformity are discussed. Copyright © 2003 John Wiley & Sons, Ltd.     

Bioethicists Can and Should Contribute to Addressing Racism

The problems of racism and racially motivated violence in predominantly African American communities in the United States are complex, multifactorial, and historically rooted. While these problems are also deeply morally troubling, bioethicists have not contributed substantially to addressing them. Concern for justice has been one of the core commitments of bioethics. For this and other reasons, bioethicists should contribute to addressing these problems. We consider how bioethicists can offer meaningful contributions to the public discourse, research, teaching, training, policy development, and academic scholarship in response to the alarming and persistent patterns of racism and implicit biases associated with it. To make any useful contribution, bioethicists will require preparation and should expect to play a significant role through collaborative action with others.     

Intersectionality in Clinical Medicine: The Need for a Conceptual Framework

Intersectionality has become a significant intellectual approach for those thinking about the ways that race, gender, and other social identities converge in order to create unique forms of oppression. Although the initial work on intersectionality addressed the unique position of black women relative to both black men and white women, the concept has since been expanded to address a range of social identities. Here we consider how to apply some of the theoretical tools provided by intersectionality to the clinical context. We begin with a brief discussion of intersectionality and how it might be useful in a clinical context. We then discuss two clinical scenarios that highlight how we think considering intersectionality could lead to more successful patient–clinician interactions. Finally, we extrapolate general strategies for applying intersectionality to the clinical context before considering objections and replies.     

Post‐identification feedback,confidence and recollections of witnessing conditions in child witnesses

Eyewitness confidence and detailed memory reports are often considered reliable indicators of the credibility of the eyewitness testimony. This study investigated how feedback concerning the accuracy of a lineup identification influences witnesses' confidence in the accuracy of their identification decision and their judgements concerning the witnessing experience. Fifty‐seven children (11–12 years) and 55 adults (17–39 years) viewed a video of a robbery and attempted to identify the culprit from a photo lineup. The culprit was not present. Participants received confirming feedback, disconfirming feedback, or no feedback on the accuracy of their identification. The confidence judgements and recollections of witnessing conditions of both children and adults were influenced by confirming and in some instances, disconfirming feedback. These findings imply that confidence and memory reports are easily distorted by non‐specific feedback and investigators should be sensitive to this particularly when dealing with vulnerable witnesses such as children.

The effects of social influence on children's memory reports: the omission and commission error asymmetry

Children in two age groups (7 vs. 12 yrs, N= 174) individually interacted with a stranger and were later interviewed about this event. Right before the interview, each child encountered the stranger once again and he engaged in a conversation where he either suggested that a (central or peripheral) detail originally present in the event had actually not been there or that an originally non-present (central or peripheral) detail had in fact been there. It was hypothesized that the two types of misinformation would result in omission and commission errors respectively. The results showed that the social influence resulted in an asymmetric effect (i.e., more commission than omission errors). Importantly, we also found that the children made more errors with respect to the peripheral detail (a suitcase), compared to the central detail (a passenger). Younger children did not make more errors (neither omission nor commission errors) than older children.     

Tracking conversational repetition: an evaluation of target monitoring ability

The ability to track who one tells information to (target monitoring) is evaluated in the present study. Participants shared personal information with target persons across four sessions spaced one day apart, and were instructed not to duplicate information to the same person over successive conversations. Target monitoring success was evaluated both on‐line, during the information sharing sessions, and retrospectively, following the final session. On‐line monitoring, or avoiding telling someone what you told them before, was very good with only one prior shared fact (Sessions 2 and 3), but declined with two prior shared facts (Session 4). Retrospective monitoring, or remembering prior fact‐to‐person assignments, was most accurate for Session 1, but dropped off sharply for Session 2 and remained constant through Session 4. Temporal errors in retrospective fact‐to‐person assignment tend to shift forward in days (telescoping). Further research is needed on the complex interrelationship of source and target information exchanges. Copyright © 2006 John Wiley & Sons, Ltd.     

Infant-mother attachment can be improved through group intervention: a preliminary evaluation in Spain in a non-randomized controlled trial

The quality of infant-mother attachment has been linked to competence in different domains of child development. Research indicates that early intervention can enhance the quality of infant-mother attachment, though its efficacy in a group format has yet to be evaluated. The current study is aimed at examining the usefulness of a group intervention in enhancing infant-mother attachment. An intervention aimed at addressing aspects such as maternal responsivity, sensitivity and childrearing behaviour was developed by the researchers and experienced psychologists. The intervention spanned a period of 14 months starting from the third quarter of pregnancy. The intervention was evaluated among 24 mothers from the Basque region of Spain. The sample consisted of children of both genders in a similar proportion: 45.8% were boys and 54.2% were girls. The children in this sample were full-term born and did not present symptoms of any serious pre- or postnatal complications. The intervention had a statistically non-significant medium effect. Infants whose mothers had received the intervention showed higher rates of secure attachment compared to children from the control group, as assessed by the Strange Situation observation procedure. A potentially significant confounding variable, maternal attachment, was balanced across the intervention and comparison groups. We can tentatively point out that a group intervention may enhance the quality of infant-mother attachment. Nevertheless, because the study design was not randomized, the results of this study remain preliminary and need replication in a full randomized controlled trial designed study.     

I saw it for longer than you: the relationship between perceived encoding duration and memory conformity

The memory conformity effect is when people's memories become similar to one another's following a discussion. The present study examined whether an individual's beliefs in the quality of their memory, relative to another person's, mediates susceptibility to memory conformity. Perceived encoding duration was manipulated by telling dyad members that one person had encoded a set of pictures for either half or twice as long as their partner. In fact, actual encoding duration was the same for all participants. Dyad members each encoded slightly different versions of otherwise identical pictures and discussed them prior to an individual free recall test. Participants who believed that they had encoded the pictures for half as long as their partner were more susceptible to memory conformity, as indicated by their increased tendency to report errant items at test that had been encountered from their partner rather than items that they had actually seen. This effect of perceived encoding duration on memory conformity was mediated through response order. A source monitoring test found that these unseen items were errantly attributed to the pictures approximately 50% of the time. The findings are discussed in relation to the role of metamemory in susceptibility to memory conformity.
