Eyewitness memory: The impact of a negative mood during encoding and/or retrieval upon recall of a non-emotive event

The police often appeal for eyewitnesses to events that were unlikely to have been emotive when observed. An eyewitness, however, may be in a negative mood whilst encoding or retrieving such events as mood can be influenced by a range of personal, social, and environmental factors. For example, bad weather can induce a negative mood. This experiment compared the impact of negative and neutral moods during encoding and/or retrieval upon eyewitness recall of a non-emotive event. A negative mood during encoding had no impact upon the number of correct details recalled (provided participants were in a neutral mood at retrieval) but a negative mood during retrieval impaired the number of correct details recalled (provided participants were in a neutral mood at encoding). A negative mood at both time points enhanced the number of correct details recalled, demonstrating a mood-dependent memory enhancement. The forensic implications of these findings are discussed.     

Cortisol response and psychological distress predict susceptibility to false memories for a trauma film

For eyewitness testimony to be considered reliable, it is important to ensure memory remains accurate following the event. As many testimonies involve traumatic, as opposed to neutral, events, it is important to consider the role of distress in susceptibility to false memories. The aim of this study was to investigate whether cortisol response following a stressor would be associated with susceptibility to false memories. Psychological distress responses were also investigated, specifically, dissociation, intrusions, and avoidance. Participants were allocated to one of three conditions: those who viewed a neutral film (N?=?35), those who viewed a real trauma film (N?=?35), and a trauma “reappraisal” group where participants were told the film was not real (N?=?35). All received misinformation about the film in the form of a narrative. Participants provided saliva samples (to assess cortisol) and completed distress and memory questionnaires. Cortisol response was a significant predictor of the misinformation effect. Dissociation and avoidance were related to confabulations. In conclusion, following a stressor an individual may differ with regard to their psychological response to the event, and also whether they experience a cortisol increase. This may affect whether they are more distressed later on, and also whether they remember the event accurately.     

An examination of the roles of trauma exposure and posttraumatic stress disorder on emotion regulation strategies of Operation Iraqi Freedom,Operation Enduring Freedom,and Operation New Dawn veterans

Theories of posttraumatic stress disorder (PTSD) implicate emotional processes, including difficulties utilizing adaptive emotion regulation strategies, as critical to the etiology and maintenance of PTSD. Operation Iraqi Freedom, Operation Enduring Freedom, and Operation New Dawn (OIF/OEF/OND) veterans report high levels of combat exposure and PTSD. We aimed to extend findings suggesting that emotion regulation difficulties are a function of PTSD, rather than combat trauma exposure or common comorbidities, to OIF/OEF/OND veterans, in order to inform models of PTSD risk and recovery that can be applied to returning veterans. We tested differences in emotion regulation, measured with the Difficulties in Emotion Regulation Scale and Emotion Regulation Questionnaire, among trauma-exposed veterans with (n = 24) or without PTSD (n = 22) and healthy civilian comparison participants (n = 27) using multivariate analyses of covariance, adjusting for major depressive disorder, anxiety disorders, and demographic variables (age, sex, and ethnicity). Veterans with PTSD reported more use of expressive suppression and more difficulties with emotion regulation than veterans without PTSD and healthy comparison participants. Groups did not differ on cognitive reappraisal. Findings suggest the key role of PTSD above and beyond trauma exposure, depression, and anxiety in specific aspects of emotion dysregulation among OIF/OEF/OND veterans. Interventions that help veterans expand and diversify their emotion regulation skills may serve as helpful adjunctive treatments for PTSD among OIF/OEF/OND veterans.     

Associations between parental gendered attitudes and behaviours and children’s gender development across middle childhood

The present study used a longitudinal, multi-informant approach to examine which specific elements of parents’ gendered attitudes and behaviours were predictive of multiple dimensions of children’s gender development. One hundred and six families with two children (older sibling M = 7.45 years and younger sibling M = 5.19 years at Time 1) were assessed at two time points four to five years apart. At Time 1, parents reported on division of household labour, their own gender-role attitudes (GRAs), and children’s gendered preferences. At Time 2, children reported on their gendered preferences, GRAs and gendered personality traits. Results from multilevel modelling showed that fathers’ egalitarian GRA and egalitarian division of household tasks were predictive of egalitarian child GRA and outcomes, but child sex did not moderate these relationships. As some gender measures were more strongly correlated than others, these findings highlight the importance of examining multiple dimensions of both children’s and parents’ gendered attitudes and behaviours.     

A Method for Analyzing Videotaped Genetic Counseling Sessions

This study describes the development and evaluation of a multi-item scale for analyzing the genetic counseling process, the Manchester Observation Code (MOC) for genetic counseling. The instrument is specific to the field of genetic counseling and is designed for analysis of the communication between counselor and client. Coding is done directly from videotaped sessions. Because communication is the means by which genetic counseling is accomplished, the method measures four relevant components of communication: (1) grammatical form, (2) purpose, (3) subject, and (4) cue source. The instrument enables an observer to code the counselor's statements into these four components. Three videotaped sessions were used to measure interrater reliability, or the consistency of rating for each of the four communication domains using this method. Three videotaped sessions were also used to measure test-retest reliability, or the consistency of the designed method from one time to another. A total of 21 videotaped sessions were tested using the method. A statistical measure of reliability established consistency of the designed method; Cohen's kappa yielded 0.7 for interrater reliability and 0.79 for test-retest reliability. These findings suggest this instrument may be used to identify important elements of the genetic counseling process.     

Assessing the generality and durability of interview‐informed functional analyses and treatment

Due to the limited research demonstrating socially valid outcomes of function‐based treatments in ecologically relevant environments (Santiago, Hanley, Moore, & Jin, 2016), we replicated and extended the effects of the interview‐informed functional analysis and skill‐based treatment procedure described by Hanley, Jin, Vanselow, and Hanratty (2014) with two children diagnosed with autism in a home setting. The assessment and treatment was implemented by a home‐based service provider and treatment was extended to the participants’ parents. Following the interview‐informed functional analyses, we taught the participants functional communication responses and to engage in less‐preferred activities when functional communication outcomes were delayed. We observed large reductions in problem behavior following the introduction of the function‐based treatment. The effects extended to novel settings, stimuli, and caregivers and the results maintained at 6‐week follow‐ups.     

How fair versus how long: An integrative theory-based examination of procedural justice and procedural timeliness

Although studies have linked procedural justice to a range of positive attitudes and behaviors, the focus on justice has neglected other aspects of decision-making procedures. We explore one of those neglected aspects: procedural timeliness—defined as the degree to which procedures are started and completed within an acceptable time frame. Do employees react to how long a procedure takes, not just how fair it seems to be? To explore that question, we examined the potential effects of procedural timeliness using six theories created to explain the benefits of procedural justice. This integrative theory-based approach allowed us to explore whether “how long” had unique effects apart from “how fair.” The results of a three-wave, two-source field study showed that procedural timeliness had a significant indirect effect on citizenship behavior through many of the theory-based mechanisms, even when controlling for procedural justice. A laboratory study then replicated those effects while distinguishing procedures that were too fast versus too slow. We discuss the implications of our results for research on fostering citizenship behavior and improving supervisors’ decision-making procedures.     

No evidence that alcohol intoxication impairs judgments of learning in face recognition

Alcohol use is frequently involved in crime, making it crucial to understand the role of alcohol in facial recognition to maximize correct perpetrator identifications. Although the majority of the alcohol and face recognition research has investigated recognition with retrospective confidence judgments, we examined the effects of alcohol intoxication on face recognition with prospective metacognitive judgments. Participants (N = 54 university students without a history of hazardous alcohol/substance use) consumed either alcohol (mean breath alcohol concentration of 0.06 at pretest and 0.07 at post‐test) or a non‐alcoholic placebo drink. Participants then studied unfamiliar male and female faces and made judgments of learning (JOLs) for each face (i.e., predicted the likelihood of recognizing that face on a future memory test). After a brief distractor task, participants completed an old–new recognition test on which they attempted to distinguish the studied faces from new faces. It was found that the alcohol manipulation had minimal effect on face recognition performance or judgments of learning. Our results suggest that theory‐based cues about the effects of alcohol might play a greater role in retrospective judgments than prospective judgments. Although not a primary focus of the study, face recognition was better for male faces than female faces, and this occurred for both female and male participants. Limitations and implications of the research are discussed.
