Discrepancy detection in the retrieval-enhanced suggestibility paradigm

Retrieval-enhanced suggestibility (RES) refers to the finding that immediately recalling the details of a witnessed event can increase susceptibility to later misinformation. In three experiments, we sought to gain a deeper understanding of the role that retrieval plays in the RES paradigm. Consistent with past research, initial testing did increase susceptibility to misinformation – but only for those who failed to detect discrepancies between the original event and the post-event misinformation. In all three experiments, subjects who retrospectively detected discrepancies in the post-event narratives were more resistant to misinformation than those who did not. In Experiments 2 and 3, having subjects concurrently assess the consistency of the misinformation narratives negated the RES effect. Interestingly, in Experiments 2 and 3, subjects who had retrieval practice and detected discrepancies were more likely to endorse misinformation than control subjects who detected discrepancies. These results call attention to limiting conditions of the RES effect and highlight the complex relationship between retrieval practice, discrepancy detection, and misinformation endorsement.     

Towards a new way of healing: experienced counsellors’ perceived influences of ch’i-related experiences on counselling practice in Taiwan

This narrative study explored how the experienced counsellors utilised the idea and practice of ch’i during counselling sessions. The data were co-constructed between the researcher and 12 senior counsellors with substantial ch’i-related experiences using a semi-structured in-depth interview method and were analysed employing a narrative analysis approach. The core themes emerging from the study were (a) an embodiment, which included two sub-themes: ch’i as a way of expressing health and illness and ch’i-related exercise lived out as an embodiment, and (b) ch’i as a way of understanding. The findings pointed to ‘a new way of healing’, which involves perceiving, containing and conveying ch’i and requires counsellors to empty themselves, and remain in a state of non-action and wholeness.     

A Systematic Review of the Posttraumatic Stress Disorder Checklist (PCL)

In this systematic review, the authors analyzed 336 published articles and dissertations that used the Posttraumatic Stress Disorder Checklist (PCL) to determine the reliability and validity of scores on 3 different versions: PCL–Specific, PCL–Military, and PCL–Civilian. Results confirmed Weathers, Litz, Herman, Huska, and Keane's ( 1993 ) claim that the PCL has adequate psychometric properties and appears to support the construction of a new version, the PCL‐5, as a population‐nonspecific instrument.     

Do Smarter People Employ Better Decision Strategies? The Influence of Intelligence on Adaptive Use of the Recognition Heuristic

Within the adaptive toolbox approach, it has repeatedly been shown that, on average, people tend to adapt their decision strategies to the decision context. Building upon these results, we investigated whether individuals systematically differ in their ability to successfully adapt to the situation when applying the fast‐and‐frugal recognition heuristic (RH). In decisions between recognized and unrecognized choice objects, individuals can base their choices solely on recognition, as predicted by the RH, or they can use further knowledge retrieved from memory. Since intelligence has been conceived as the ability to successfully adapt to different situations, we expected intelligence to influence the degree of adaptive use of the RH. To test this hypothesis, we first re‐analyzed data that referred to a decision domain for which RH‐use is known to perform well. As expected, individual RH‐use increased with general intelligence. Next, we designed an experiment addressing individual RH‐use in two new decision domains, one domain for which RH‐use was less effective than knowledge‐use and another domain for which both strategies were about equally effective. In addition, we tested whether fluid or crystallized intelligence best predicts adaptive use of the RH. RH‐use was found to decrease with fluid but not crystallized intelligence when RH‐use was less effective than use of further knowledge. In contrast, there was no significant association between either type of intelligence and RH‐use when none of the two strategies was optimal. We conclude that adaptive use versus non‐use of the RH is moderated by fluid intelligence. Copyright © 2017 John Wiley & Sons, Ltd.     

Measurement Error-Corrected Estimation of Clinically Significant Change Trajectories for Interventions Targeting Comorbid PTSD and Substance Use Disorders in OEF/OIF Veterans

In randomized control trials (RCTs), a focus on average differences between treatment arms often limits our understanding of whether individuals show clinically significant improvement or deterioration. The present study examined differences in individual-level clinical significance trajectories between Concurrent Treatment of PTSD and Substance Use Disorders Using Prolonged Exposure (COPE) and Relapse Prevention (RP). Eighty-one treatment-seeking veterans with a comorbid PTSD/SUD diagnosis were randomized to COPE or RP; data from an additional n = 48 patients who did not meet criteria for both disorders was used to establish a normative threshold. A newly developed, modernized approach to the Jacobson and Truax (1991) clinically significant change framework, using (a) moderated nonlinear factor analysis (MNLFA) scale scoring and (b) measurement error-corrected multilevel modeling (MEC-MLM) was used; this approach was compared to other approaches using conventional total scores and/or assuming no measurement error. Using a conventional approach to estimating the Reliable Change Index (RCI) yielded no differences between COPE and RP in the percentage of patients achieving statistically significant improvement (SSI; 88.9% for both groups). However, under MNLFA/MEC-MLM, higher percentages of patients receiving COPE (75.0%) achieved SSI compared to RP (40.7%). Findings suggest that, even though COPE and RP appear to reduce the same number of PTSD symptoms, MNLFA scoring of outcome measures gives greater weight to interventions that target and reduce “hallmark” PTSD symptoms.     

A scoping review of predictors of driving under the influence of cannabis (DUIC) in young drivers

BackgroundRecreational and medical legalization of cannabis or marijuana use in countries and states continues to increase. Young adults aged 16–24 years have the highest prevalence rates of cannabis use. Young driver cannabis use is an incompletely understood traffic safety issue.ObjectivesThe purposes of this scoping review were to characterize the predictors of driving under the influence of cannabis (DUIC) among healthy young drivers and to identify research gaps.Inclusion criteriaA self-reported measure of DUIC and a correlation (r, odds ratio, risk ratio) to demographic or behavioral variables such as age, gender and frequency of use was required for inclusionSources of evidenceAPA PsycInfo, SPORTDiscus, Academic Search Complete, Google Scholar, MEDLINE Complete, Scopus, Embase, ERIC, TRID and POPLINE databases were searched using an a priori protocol.MethodsThe PRISMA-ScR methods and checklist were used to conduct the scoping review. After the removal of duplicates, abstract screening (N = 999), and full-text review (N = 173), 19 primary studies met inclusion criteria. Predictors were coded and mapped into four primary thematic categories: social, individual, driving and substance use.ResultsOf the included studies, a total of 52,197 respondents were surveyed in-person or online and 51.8 percent were males. The predominant predictors of DUIC included being a male, high school senior, with lower grades, having a younger ‘age of first cannabis use’, a higher frequency of consumption, a reduced perception of danger, repeatedly binge drinking, a history of driving under the influence of alcohol and living with fewer parents.Research gapsIdentified research gaps include methods used to study young drivers, cannabis edibles, chronic user tolerance, driver adaptation, passengers of drivers who consumed cannabis, combined use with other legal and illicit drugs, and combined smartphone and cannabis use.ConclusionThe results of this scoping review can be used to develop and target general and specific predictors of DUIC in novice, teen and young drivers. Additional research designs will be required to gain a more complete evidence-based understanding of the effects of cannabis on young drivers.

Analyse du cadre réglementaire des certificats médicaux demandés par une municipalité en 2019

Medical certificates have a regular place in general medicine consultation. Since 2011, the french law has highlighted the absence of regulatory support of certain certificates, in particular of public services. The objective of this study was to find out which regulatory texts were based on the medical certificates required by a municipal administration, 8 years after the 2011 rationalization circular?Material and methodQualitative study by observation and critical analysis of certificates by literature reviews according to the main PRISMA quality criteria (Preferred Reporting Items for Systematic Reviews and Meta-Analyzes). The first step consisted of the exhaustive collection of the medical certificates provided by the municipality, for the citizens or the employees of the city. The origin of one of the municipal services was the only criterion for inclusion. The second stage consisted in analyzing the certificates according to the law by using databases classified depending on their level, taking their regulatory value into account as a priority. The research equations were constructed with an inductive process as the certificates were collected.ResultsForty-two certificates were collected and analyzed. Twenty-seven had regulatory support, two of which (not concerned in general medicine) complied with its content. No regulatory support was found for the 15 other certificates. The regulatory vagueness around sports accidents, or even the abuse of authority, are explanations for these certificates without existing or respected regulatory support.ConclusionThe general practitioner is put in a difficult and ambivalent position. A major institutional commitment should be considered for the rationalization of medical certificates, in particular through medical education, health education for users and law enforcement.     

Computational modeling of organisational learning by self-modeling networks

Within organisational learning literature, mental models are considered a vehicle for both individual learning and organizational learning. By learning individual mental models (and making them explicit), a basis for formation of shared mental models for the level of the organization is created, which after its formation can then be adopted by individuals. This provides mechanisms for organizational learning. These mechanisms have been used as a basis for an adaptive computational network model. The model is illustrated by a not too complex but realistic case study.
