This article offers an account of the 50th Ghanaian independence-day celebrations during March 2007. The multi-perspective approach examines how celebrations were experienced in the Ghanaian capital Accra by the political elite and the grass roots at a variety of official and unofficial events that took place on 5 and 6 March 2007. During the festivities the authors accompanied Ghanaian friends from different political factions and thus provide close-hand accounts of political controversies over issues regarding how the nation ought to organise and celebrate its Independence Day, controversies which provide important insights into Ghanaian political culture. From this it is clear that the celebrations not only serve as expressions of national pride but also moments of critical reflection on the nation, national values and socio-political unity. These reflections, manifest as disputes about national and ethnic symbols, centre on the conditions and limits of political, social, ethnic and regional inclusiveness. At the same time, underlying such disputes are commonalities resting not on substantive symbols, cultural traits or other objectifiable characteristics, but on a Ghanaian consensus to agree on the issues at stake and on the rules of debate. Controversy thus functions not to divide but rather to strengthen national consciousness and deepen a sense of commonality that Ghanaians generally express as their commitment to ‘unity in diversity’.

Purpose: Several studies have documented that people's ability to correctly report details of witnessed events is enhanced when they merely close their eyes. Yet closing one's eyes in front of a stranger could sometimes create social discomfort, which other studies suggest can impair memory reports. This paper reports two experiments exploring the extent to which the memory benefits of eyeclosure are enhanced when efforts are taken to build interviewer/witness rapport, thus potentially reducing discomfort. Methods: In both studies participants observed filmed events and, afterwards, half underwent a basic rapport-building exercise with an interviewer. All participants then answered closed questions about specific details of the event, and half were instructed to close their eyes throughout this questioning. We recorded the proportion of questions answered correctly, incorrectly, or with 'don't know' responses. Results: Both eyeclosure and rapport-building separately enhanced correct responding. The data offer no evidence, though, that rapport-building moderated this eyeclosure benefit. This is despite the fact that rapport-building did appear to moderate the effect of eyeclosure on participants' self-reported comfort during the interviews. Conclusions: These studies give us initial cause for doubt over a hypothesized - but heretofore untested - social psychological constraint on the benefits of eyeclosure.

Eyewitnesses have always played a fundamental role in the legal process. However, eyewitness evidence is not always as reliable or as accurate as one might hope, given the weight that decision-makers often ascribe to it. In this article, we review some of the many factors that can determine the reliability of witness testimony, including factors that are, and those that are not, within the control of investigative and judicial processes. In doing so, we consider how policies might assist in ensuring that witness testimony can play the most effective and informative role in the legal process as possible.

False information can influence people's beliefs and memories. But can fabricated evidence induce individuals to accuse another person of doing something they never did? We examined whether exposure to a fabricated video could produce false eyewitness testimony. Subjects completed a gambling task alongside a confederate subject, and later we falsely told subjects that their partner had cheated on the task. Some subjects viewed a digitally manipulated video of their partner cheating; some were told that video evidence of the cheating exists; and others were not told anything about video evidence. Subjects were asked to sign a statement confirming that they witnessed the incident and that their corroboration could be used in disciplinary action against the accused. See-video subjects were three times more likely to sign the statement than Told-video and Control subjects. Fabricated evidence may, indeed, produce false eyewitness testimony; we discuss probable cognitive mechanisms. Copyright © 2009 John Wiley & Sons, Ltd.

In attempting to impeach eyewitnesses, attorneys often highlight inconsistencies in the eyewitness's recall. This study examined the differential impact of types of inconsistent testimony on mock-juror decisions. Each of 100 community members and 200 undergraduates viewed one of four versions of a videotaped trial in which the primary evidence against the defendant was the testimony of the eyewitness. I manipulated the types of inconsistent statements given by the eyewitness in the four versions: (1) consistent testimony, (2) information given on-the-stand but not given during the pre-trial investigation, (3) contradictions between on-the-stand and pre-trial statements, and (4) contradictions made on the witness stand. Subjects exposed to any form of inconsistent testimony were less likely to convict and found the defendant less culpable and the eyewitness less effective. These effects were larger for contradictions than for information given on the stand but not during pre-trial investigations. ^

Mistaken eyewitness identifications of innocent lead to more false convictions in the United States than any other cause. In response to concerns about the reliability of eyewitness evidence, the National Institute of Justice (NIJ) in 1999 published a Guide for the gathering and preservation of eyewitness evidence by law enforcement personnel. Previous research has shown that eyewitness identifications are more accurate when obtained using procedures recommended in the NIJ Guide. This experiment assessed whether informing jurors about the Guide can improve their ability to discriminate between eyewitness identifications likely to be accurate and those likely to be inaccurate and, if so, how to most effectively provide jurors with such information. ^ Seven hundred sixteen U.S. citizens who reported for criminal jury duty participated. Half of the participant jurors read a summary of an armed robbery trial in which the police followed the NIJ Guide when obtaining an eyewitness identification of the defendant. The other half read about an identical case in which the police did not follow the Guide. Jurors received information about the Guide from a court-appointed expert witness, one of the attorneys in the case, the trial judge, the judge in combination with one of the attorneys, or from no one (in the control groups). Jurors then rendered a verdict in the case and answered questions about the evidence in the case. ^ When an expert witness or the judge (either alone or in combination with one of the attorneys) informed jurors about the Guide, the jurors voted to convict defendants likely to be guilty and to acquit defendants likely to be innocent more often than did uninformed jurors assigned to a control group. These data suggest that informing jurors about the NIJ Guide using expert testimony or instructions from a judge will improve the quality and accuracy of jurors' verdict decisions in cases involving eyewitness identification evidence. However, more research is needed to determine whether the judge will remain an effective source of information about the Guide in a longer, more detailed trial scenario and to learn more about the underlying psychological processes governing the effects observed in this experiment. ^

Historically, memory has been evaluated by examining how much is remembered, however a more recent conception of memory focuses on the accuracy of memories. When using this accuracy-oriented conception of memory, unlike with the quantity-oriented approach, memory does not always deteriorate over time. A possible explanation for this seemingly surprising finding lies in the metacognitive processes of monitoring and control. Use of these processes allows people to withhold responses of which they are unsure, or to adjust the precision of responses to a level that is broad enough to be correct. The ability to accurately report memories has implications for investigators who interview witnesses to crimes, and those who evaluate witness testimony. ^ This research examined the amount of information provided, accuracy, and precision of responses provided during immediate and delayed interviews about a videotaped mock crime. The interview format was manipulated such that a single free narrative response was elicited, or a series of either yes/no or cued questions were asked. Instructions provided by the interviewer indicated to the participants that they should either stress being informative, or being accurate. The interviews were then transcribed and scored. ^ Results indicate that accuracy rates remained stable and high after a one week delay. Compared to those interviewed immediately, after a delay participants provided less information and responses that were less precise. Participants in the free narrative condition were the most accurate. Participants in the cued questions condition provided the most precise responses. Participants in the yes/no questions condition were most likely to say “I don’t know”. The results indicate that people are able to monitor their memories and modify their reports to maintain high accuracy. When control over precision was not possible, such as in the yes/no condition, people said “I don’t know” to maintain accuracy. However when withholding responses and adjusting precision were both possible, people utilized both methods. It seems that concerns that memories reported after a long retention interval might be inaccurate are unfounded. ^
