Recall of unpleasant emotion using memory-enhancing principles

Abstract

Two experiments are presented to examine the issue of memory for past emotions. Participants rated their emotional reactions on the occasion of watching a film, and in a subsequent session, they were asked to recall and rate the emotion as experienced when viewing it. In the first experiment, participants underestimated unpleasant emotion at recall, but their recall was improved with the presentation of a visual cue pertaining to the emotion-inducing film event. In the second experiment, participants were assisted in probing perceptual aspects of the event by means of memory-enhancing instructions underlying the Cognitive Interview. These participants consistently recalled emotional intensity, as compared to participants in the unassisted recall condition who underestimated prior emotion. This research suggests that ratings of prior emotion are easily influenced by features of the retrieval context, and that consistent recall may be achieved by memory-enhancing principles of the Cognitive Interview.     

Effects of Mug Book Size and Computerized Pruning on the Usefulness of Dynamic Mug Book Procedures

Abstract

A recurrent problem for the legal system is persons claiming memory loss in relation to crime events of which they are suspected. In the present study, individuals were tested as perpetrators having first read a story about “themselves” stabbing another man to death. Participants' memory of the story was tested at three sessions (30 minutes, one week and three weeks later). The genuine memory of one group was tested at all three sessions, whilst a second group simulated memory impairments at the first session and a third group simulated memory impairments at the first two sessions. At the third test session, all three groups were tested on what they actually remembered. Results showed a decrease in memory after simulation of impaired memory, as compared with the controls, but repeated simulation did not seem to be of importance for free recall and recognition. It is suggested that people have specific ideas and conceptions about how memory and forgetting work, ideas that might be used when simulating memory impairments in order to deny guilt. Although one should be cautious when generalizing the findings to real life events, the results are considered to be of relevance within both the legal- and the memory theoretical frameworks.     

The cognitive interview and its effect on misleading postevent information

Abstract

The present study investigated the effectiveness of the cognitive interview on reducing the impact of the misinformation effect. A 2×2 between-groups design was used, with interview type (cognitive or structured) and narrative type (misleading or neutral) as the independent variables. Adults (n=40) viewed video footage depicting a bank robbery and then received either a misleading or neutral postevent narrative. Participants were interviewed with either a cognitive or a structured interview regarding their memory for the original footage. The cognitive interview produced significantly more correct pieces of information than the structured interview, without an increase in errors or confabulations. An anomalous significant interaction was found regarding the number of incorrect pieces of information, where recipients of the structured interview made more recall errors when receiving neutral postevent information compared to neutral postevent information. A misinformation effect was successfully achieved but the enhancing effects of the cognitive interview were unable to reduce it. Results are discussed within the misinformation effect theoretical framework. The limitations of the present study are also discussed.     

Mighty Morphin’ age progression: how artist,age range,and morphing influences the similarity of forensic age progressions to target individuals

When children go missing, authorities sometimes release age progressed images that are intended to approximate the person's current appearance. The current studies measured the influence of the range between the time when the child went missing and the age portrayed in the age progression on the similarity between the progressions and current images of the targets. Experiment 1 examined whole face images and Experiment 2 examined internal features only. Eight artists were recruited to produce progressions at three age ranges. Also included were averaged (morphed) images made of progressions of the same individual at a given range by different artists. Progressions across shorter ranges produced images more similar than those across longer ranges, and target comparisons yielded higher similarity ratings than foil comparisons. Although there was much variability among artists, the morphed images performed better than the average rating given to all age progressions.     

The effects of target discriminability and criterion placement on accuracy rates in sequential and simultaneous target-present lineups

Abstract

Participants attempted to select previously studied faces from lineups that were administered either sequentially (test faces presented one at a time) or simultaneously (test faces presented altogether). Target discriminability was manipulated by varying the number of facial features that could be used to distinguish the study face from the other test faces (foils) or by varying study face exposure duration. In addition, decision criterion level was manipulated via an instruction manipulation. Results indicated that sequential participants adopted a stricter decision standard under high criterion instructions compared to simultaneous participants. Under liberal criterion setting instructions, the rate at which the target was selected was comparable across lineup procedures. Target discriminability affected target selections to a greater extent in simultaneous compared to sequential lineups. We discuss the applied implications that these findings have regarding correct identifications from lineups.     

The relationship between intelligence,memory and interrogative suggestibility in young offenders

Abstract

The study investigated the relationship between interrogative suggestibility and relevant cognitive factors as proposed by Gudjonsson and Clark (1986). The subjects were fifty-eight adolescent young offenders resident in a national children's centre with secure facilities. All were administered the Gudjonsson Suggestibility Scale and the Wechsler Intelligence Scale for Children. Interrogative suggestibility correlated negatively with intelligence and recall memory. Limited evidence of range effects was found for the relationship between intelligence and suggestibility, but not for the relationship between recall memory and suggestibility.     

Mental reinstatement of context with child witnesses: does it matter whether context is reinstated ‘out loud’?

Abstract

In this study we examined the impact of two types of mental reinstatement of context instructions in facilitating children's recall of a staged event across two stages of development. Specifically, a 2 × 3 factorial design was utilised incorporating two age groups (6- and 12-year-olds) and three interview conditions (standard recall, mental reinstatement where the child was instructed to reinstate the context ‘out loud’, and mental reinstatement without the explicit ‘out loud’ instruction). Overall, mental reinstatement instruction led to more correct and fewer incorrect responses than the standard recall instruction. The effect of mental reinstatement was similar across the age groups and irrespective of whether the child was asked to reinstate ‘out loud’. Beneficial effects of the technique, however, were only evident for cued-recall questions as opposed to free-narrative responses. The implications of these findings and directions for future research are discussed.     

Gender effects in eyewitness accounts of a violent crime

Abstract

This research examined two aspects of gender effects in eyewitness accounts: whether there are gender differences in memory for a violent crime and how gender of perpetrator/victim affect witnesses' evaluations of perpetrator/victim behavior. Eighty male and 84 female university students saw a film showing a simulated manslaughter with either a male or female perpetrator stabbing a male or female victim. A female advantage was found in overall memory of the crime, and both a male perpetrator and a male victim were assigned more culpability than their female counterparts. It is suggested that females may have more elaborated categories for person information than males, which should facilitate female accuracy in person memory. Alternatively, the present findings may reflect a more general female advantage in episodic memory performance. Stereotype assimilation is suggested to account for the differential evaluations of a male and female perpetrator/victim.     

How reliable are eyewitness memories? Effects of retention interval,violence of act,and gender stereotypes on observers' judgments of their own memory regarding witnessed act and perpetrator

An experiment was conducted to evaluate the effects of (i) stimulus person's gender, (ii) type of act (neutral or violent), and (iii) retention interval (short or long) on observers' memory of a stimulus person. Participants were presented with one of two acts: neutral (walking around in a store) or violent (robbing a store). The retention interval was 10 minutes or one–three weeks. The dependent variables were questionnaire items concerning the participants' memory of (1) the stimulus person's appearance and (2) the event, and (3) rating scales where the participants were asked to evaluate the stimulus person's aggressiveness, insensitivity, and other personality traits as well as characteristics of the act. Results showed that when the act was violent, and a long retention interval was used, a female, but not a male, stimulus person was evaluated less harshly than with a short retention interval (enhancement of gender stereotype); a stimulus person was seen as behaving in a more masculine way when performing a violent rather than a neutral act; witnessing the violent act resulted in better self-rated memory of the stimulus person; and with increasing retention interval, the violent act was seen as less negative and the neutral act as more negative (regression toward the mean).     

Nostalgias

Abstract

This paper launches a thought experiment the aim of which is to recover and defend an idea of nostalgia as something other than merely maudlin yearning after the days of yore. Much critical comment on nostalgia, in everyday parlance and in academic debate, begins from the standpoint that the time longed for was never really as it is now, nostalgically, imagined. The force and validity of this jibe is admitted in this paper, but it argues that the concept of nostalgia can be reshaped and turned in quite different less reactive directions. A distinction between Nostalgia and nostalgias is coined in order to introduce a plural and critical version of nostalgic memory. The play of memory in nostalgias is exemplified through a focus on four topoi of experience which are strained, possibly even shattered, by the digitalisation and rationalisation of contemporary culture and society. Nostalgias of and for the body, nature, thought, and modernity itself are explored by comparison to themes of melancholy and utopia which arise in Frankfurt School critical theory as responses to a similarly perceived trauma and triumph of instrumental reason. I argue that ultimately the distinction between nostalgias and Nostalgia cannot be maintained - nostalgias are rather types or tropes of Nostalgia. However, through thinking Nostalgia along the lines of this neologism (nostalgias) we might come to see its dynamic and critical mnemonic potencies. Hence, the paper concludes that nostalgia ought not be simply contemned and dismissed as the conservative freezing of memories and images of a fake past.
