Educating jurors about eyewitness testimony in criminal cases with circumstantial and forensic evidence.

We investigated whether the Interview-Identification-Eyewitness factors (I-I-Eye) educational aid could sensitize mock jurors to the quality of eyewitness evidence in criminal cases which also contained circumstantial and forensic evidence. After participants were randomly assigned to read either the I-I-Eye or a control aid, they read a trial transcript containing either strong or weak eyewitness evidence. The police consistently followed scientific interviewing and identification procedures in the strong case, but not in the weak case. In two experiments, the I-I-Eye participants were approximately three times more likely than the control participants to enter guilty verdicts in the strong case than in the weak case. Thus the I-I-Eye educational aid increased participants' sensitivity to the eyewitness evidence. The I-I-Eye method provides a valuable analytical framework for evaluating eyewitness evidence in criminal cases. It may be capable of becoming "a standard feature for criminal cases" with eyewitness evidence.

Retrospective Appraisals Mediate the Effects of Combat Experiences on PTS and Depression Symptoms in U.S. Army Medics.

A life-threatening traumatic experience can cause physical and psychological distress, but it can also be remembered with pride from having demonstrated one's courage and abilities under severe circumstances. Characteristics of the event, early response, as well as later personal reflection, together determine the individual's response to a traumatic event. We investigated how traumatic combat experiences and retrospective appraisals of those experiences affected reports of symptoms of posttraumatic stress and depression in 324 U.S. Army medics. Higher levels of combat experiences were associated with both appraisals of threat to life (r = .40) and appraisals of personal benefit of the deployment (r = .15). Threat appraisals were associated with increases (r = .33 and .29), whereas benefit appraisals were associated with decreases (r = -.28 and -.30, respectfully), in symptoms of posttraumatic stress and depression. These opposing mediation pathways led to weak or nonsignificant total effects, which concealed the effects of combat intensity on posttraumatic stress (R(2) = .28) and depression (R(2) = .24). Acknowledging the beneficial effects that a combat experience had on one's life was associated with less intense behavioral health symptoms and offset the detrimental effects of traumatic combat experiences.

Forgetting feelings: Opposite biases in reports of the intensity of past emotion and mood.

Memory for feelings is subject to fading and bias over time. In 2 studies, the authors examined whether the magnitude and direction of bias depend on the type of feeling being recalled: emotion or mood. A few days after the U.S. Presidential elections in 2008 and 2012, participants reported how they felt about the election outcome (emotion) and how they felt in general (mood). A month after the elections, participants recalled their feelings. The intensity of past emotion was recalled more accurately than the intensity of past mood. Participants underestimated the intensity of emotion but overestimated the intensity of mood. Participants' appraisals of the importance of the election, which diminished over time, contributed to underestimating the intensity of emotion. In contrast, participants' strong emotional response to the election contributed to overestimating the intensity of mood. These opposing biases have important implications for decision making and clinical assessment.

An examination of the causes and solutions to eyewitness error.

Eyewitness error is one of the leading causes of wrongful convictions. In fact, the American Psychological Association estimates that one in three eyewitnesses make an erroneous identification. In this review, we look briefly at some of the causes of eyewitness error. We examine what jurors, judges, attorneys, law officers, and experts from various countries know about eyewitness testimony and memory, and if they have the requisite knowledge and skills to accurately assess eyewitness testimony. We evaluate whether legal safeguards such as voir dire, motion-to-suppress an identification, cross-examination, jury instructions, and eyewitness expert testimony are effective in identifying eyewitness errors. Lastly, we discuss solutions to eyewitness error.

Like Schrödinger's cat, the impact bias is both dead and alive: reply to Wilson and Gilbert (2013).

In their comment on our article on affective forecasting (Levine, Lench, Kaplan, & Safer, 2012), Wilson and Gilbert (2013) criticized the meta-analysis, proposed alternative explanations for the empirical studies, and concluded that the impact bias is alive and well. Our reply demonstrates that, irrespective of the exclusion of effects and selective recoding of effects recommended for the meta-analysis, the pattern of results remains the same: Study participants' forecasts are more accurate when they report their feelings about a focal event, or immediately after a focal event, than when they report their feelings in general after a delay. New analyses rule out individual differences and focalism as alternative explanations for the results of our empirical studies. These studies show that people can accurately predict the intensity of their feelings about events. People overestimate in predicting the impact of events on their emotional state in general, but clarifying the meaning of the forecasting question reduces the magnitude of this bias. We conclude that the impact bias, which encompasses overestimating the intensity of feelings about events and overestimating the intensity of feelings in general, is both dead and alive. The importance of predicting feelings about events for decision making and the reasons people predict some features of emotion more accurately than others are discussed.

What Italian Defense Attorneys Know about Factors Affecting Eyewitness Accuracy: A Comparison with U.S. and Norwegian Samples.

We surveyed 100 Italian defense attorneys about their knowledge and beliefs about factors affecting eyewitness accuracy. The results of similar surveys show that U.S. defense attorneys were significantly more knowledgeable than other legal professionals, including U.S. prosecutors and U.S. and European judges. The present survey of Italian defense attorneys produced similar results. However, the results suggest that the defense attorney's superior performance may be due at least in part to their skepticism of eyewitness testimony rather than their greater knowledge of eyewitness factors.

Aging and long-term memory for emotionally valenced events.

In 2008, 1103 ardent Boston Red Sox fans answered questions about their team's 2003 loss and 2004 win in baseball championship games with archrival New York Yankees. Contrary to predictions based on socioemotional selectivity theory, there were no significant interactions of age and event valence for accuracy in remembering event details, or for self-reported subjective vividness and rehearsal of the memories. Fans 65 years and older tended to remember feeling only sad about the 2003 loss, whereas fans 25 years and under tended to remember feeling both sad and angry. Individuals may remember emotional feelings based on remembered goals about an event.

Accuracy and artifact: reexamining the intensity bias in affective forecasting.

Research on affective forecasting shows that people have a robust tendency to overestimate the intensity of future emotion. We hypothesized that (a) people can accurately predict the intensity of their feelings about events and (b) a procedural artifact contributes to people's tendency to overestimate the intensity of their feelings in general. People may misinterpret the forecasting question as asking how they will feel about a focal event, but they are later asked to report their feelings in general without reference to that event. In the current investigation, participants predicted and reported both their feelings in general and their feelings about an election outcome (Study 1) and an exam grade (Study 3). We also assessed how participants interpreted forecasting questions (Studies 2 and 4) and conducted a meta-analysis of affective forecasting research (Study 5). The results showed that participants accurately predicted the intensity of their feelings about events. They overestimated only when asked to predict how they would feel in general and later report their feelings without reference to the focal event. Most participants, however, misinterpreted requests to predict their feelings in general as asking how they would feel when they were thinking about the focal event. Clarifying the meaning of the forecasting question significantly reduced overestimation. These findings reveal that people have more sophisticated self-knowledge than is commonly portrayed in the affective forecasting literature. Overestimation of future emotion is partly due to a procedure in which people predict one thing but are later asked to report another.

Effects of event valence on long-term memory for two baseball championship games.

We investigated how event valence affected accuracy and vividness of long-term memory for two comparable public events. In 2008, 1,563 fans answered questions about objective details concerning two decisive baseball championship games between the Yankees (2003 winners) and the Red Sox (2004 winners). Both between- and within-groups analyses indicated that fans remembered the game their team won significantly more accurately than the game their team lost. Fans also reported more vividness and more rehearsal for the game their team won. We conclude that individuals rehearse positive events more than comparable negative events, and that this additional rehearsal increases both vividness and accuracy of memories about positive events. Our results differ from those of prior studies involving memories for negative events that may have been unavoidably rehearsed; such rehearsal may have kept those memories from fading. Long-term memory for an event is determined not only by the valence of the event, but also by experiences after the event.

Focalism and the underestimation of future emotion: when it's worse than imagined.

People typically exaggerate the emotional impact of future events. This occurs because of focalism, the tendency to focus on one event and neglect to consider how emotion will be mitigated by the surrounding context. Neglecting context, however, should lead people to underestimate future emotion when context focuses attention on the event. In Study 1, participants underestimated the intensity of their future negative emotions when they reported reactions to a romantic break-up on Valentine's Day versus 1 week before. This relationship was mediated by how frequently they thought about the break-up. In Study 2, participants underestimated the emotional impact of a lost prize when the experimental context forced them to focus on the prize versus when the prize was less evident. Thus, failing to account for the extent to which context would focus attention on the event, a form of focalism, led to underestimation of emotional reactions to a negative event.

Killing versus witnessing in combat trauma and reports of PTSD symptoms and domestic violence.

Active participation in combat trauma increased reports of posttraumatic stress disorder (PTSD) symptoms over passive witnessing of trauma. Using archival data from 376 U.S. soldiers who took part in the family interview component of the 1988 National Vietnam Veteran Readjustment Study (NVVRS), findings are that even after statistically accounting for witnessing combat trauma, U.S. soldiers who likely killed enemy soldiers in combat reported elevated levels of PTSD symptoms. Both inference and direct self-reports were used to measure killing in combat, and both measures accounted equally well for variance in PTSD symptoms. The likelihood of a soldier killing enemy combatants was also weakly related to his spouse's report of physical domestic violence in the past year. Diagnosing the mental health symptoms of combat soldiers should specifically assess whether they actively participated in wounding or killing the enemy.

The Psychology of Referencing in Psychology Journal Articles.

Citation statistics can affect major professional decisions, but little is known about how important a particular reference is to the citing document. We asked 49 psychologists to rate the importance of every reference in their own empirical paper and to indicate the primary citation reason. References cited for conceptual ideas or to justify methods and data analyses were regarded as more important than references cited for general background, limitations, or future research. The location, frequency, and length of a citation predicted its importance, but such relationships were weaker for self-citations. We make suggestions about referencing for authors, editors, and bibliographic database designers.

The impact of suicidal rock music lyrics on youth: an investigation of individual differences.

This study attempted to predict reactions after listening to music with lyrics about suicide. One hundred and twenty-six volunteers completed self-reports of personality and mood, and then listened to the music. Afterwards, they completed projective stories, self-reports of moods and reactions, and a memory test for the lyrics. Low openness to experience, and to a lesser extent, high neuroticism and low self-esteem predicted higher levels of suicide-related content in projective story-writing, as did knowing a suicide victim. Both the personality measures and post-listening mood predicted remembering too many nihilistic lyrics. Surprisingly, 68% of participants wrote at least one projective story with altruistic content. Individual differences were modestly associated with suicidal thoughts after listening to the music.

Long-term memory for the emotional gist and the emotional essence of an experience.

We investigated accuracy in recalling past emotional behaviours and emotionality. Male couples discussed the history of their relationship, and coders rated the extent to which each partner engaged in behaviours such as complimenting or criticising. These ratings were combined into dimensions representing the deeper, emotional essence of that partner's discussion (expressions of We-ness, Fondness, Negativity, and Disappointment). Four years later, participants accurately recalled some of their own and some of their partner's emotional gist-level behaviours, but their answers indicated that they also remembered the emotional essence of the conversation. We conclude that individuals can retain the emotional essence of an experience for a long time, and that they may use this memory to infer, in part, gist-level details of the experience.

The value of forgetting suicidal thoughts and behavior.

This is a prospective longitudinal study examining recollections of suicidal content and correlates of accurate and inaccurate recollection. A primarily at-risk group of young adults (N = 78) who were initially assessed for suicidal ideation and behavior in adolescence, were asked to recall whether they had reported sui- cidal ideation or behavior about six years earlier. In recalling the previous inter- view, the majority of the participants provided consistent reports. However, with regard to those who had previously reported suicidal ideation or behavior, 38% failed to recall prior adolescent suicidal reports. Those who provided accurate reports of prior suicidal content were more symptomatic and were functioning more poorly than those who failed to recall past suicidal content. The implications for clinical assessment practices, research, and theory development are discussed.

The impact of rock videos and music with suicidal content on thoughts and attitudes about suicide.

In Experiment 1, 133 college student volunteers watched a rock music video with or without suicidal content and then completed written measures assessing mood, priming of suicide-related thoughts, perceptions of personal risk, sensitivity to suicidality in others, and attitudes/beliefs about suicide. In Experiment 2, 104 college student volunteers listened to rock music with either suicidal or neutral content and then completed measures similar to Experiment 1, with the addition of a hopelessness measure. In both experiments, participants exposed to suicidal content wrote more scenarios with suicide-related themes in a projective storytelling task than those exposed to nonsuicidal content. However, there were virtually no group differences on explicit measures of affect, attitudes, and perceptions. Music and videos with suicide content appeared to prime implicit cognitions related to suicide but did not affect variables associated with increased suicide risk.

Individual differences in misremembering pre-psychotherapy distress: personality and memory distortion.

In 2 studies, clients were asked, after terminating psychotherapy, to complete a measure of symptomatic distress exactly as they had in their pre-therapy assessment. Most clients overestimated their pre-therapy distress, which may lead to an illusion of positive change. A 3rd study found no overestimation of previously reported distress in a control sample. The degree of overestimation for psychotherapy clients was positively correlated with anxiety, depression, and neuroticism, and negatively correlated with ego strength, self-deception, and lying. Distress levels at termination mediated these effects of individual differences. Individual differences were also correlated with specific types of recall error, such as adding to, exaggerating, omitting, and minimizing previously reported symptoms. Misremembering prior emotions may both reflect and create individual differences.

The meaning of pain: cancer patients' rating and recall of pain intensity and affect.

The present study investigated the influence of an increase in present pain intensity on the rating and recall of the intensity and affective dimensions of clinical pain. Thirty-two cancer patients who reported that movement caused or exacerbated their pain rated their present pain intensity and affect before and after a session of physical therapy. Subjects also rated their usual, highest and lowest pain intensity and pain affect for the previous 3 days, and were randomly assigned to make these ratings either before or after the physical therapy session. Physical therapy increased the intensity (P < 0.01) but not the unpleasantness of the pain (P > 0.05), thus demonstrating a dissociation between pain intensity and pain affect. Beliefs about pain etiology also influenced post-therapy pain ratings. Subjects (N = 11) who believed that their pain was due to cancer, rated their post-therapy pain intensity and pain affect significantly higher than those subjects (N = 21) who did not believe their pain was due to cancer (both P < 0.05). For all subjects, recall of past pain intensity and affect was positively correlated with present levels of pain intensity and pain affect (P < 0.01). Thus, recall was assimilated to present pain levels. The results demonstrate the importance of rating both the intensity and affective dimensions of pain, and suggest that the significance of clinical pain influences pain ratings. These results also suggest that research on the rating and recall of pain, particularly the affective dimension of pain, should use actual patients who are experiencing changes in their naturally occurring pain.

Effects of present pain level on recall of chronic pain and medication use.

The present study experimentally manipulated pain intensity in chronic pain patients to evaluate whether the present pain level influenced the recall of past pain and medication use. For 1 week 30 chronic pain patients recorded every change in their pain levels and every use of medication on an electronic diary. At the end of the week, we evaluated recall of pain level and medication use for the previous day and week either before (control group, n = 15) or immediately after a physical therapy (PT) session (PT group, n = 15). As expected, the PT patients reported a significantly lower present pain level than did the control patients. More importantly, the PT patients recalled their usual and their highest levels of pain for the previous day and week to be less severe than did the control patients; furthermore, they significantly underestimated these levels as compared to their diary. In contrast, the control patients significantly overestimated their lowest and highest levels of pain for the previous day and their usual and lowest levels of pain for the previous week. In addition, PT patients recalled taking significantly less medication than they had recorded in their diaries, and less than the control patients. Our results demonstrate clearly that chronic pain patients recall their pain and medication use for the previous day and week in a way that is congruent with their present pain intensity.
