This study examined the association between victimization and victim blaming using a sample of n = 142 participants in a generalized linear mixed model (GLMM) with the influence of subject gender, victim stereotyping level, threat level, and victim gender for victim blaming. Belief in a just world was included in the model as a covariate. Mediation analyses were conducted with the degree of identifiability with the victim and attitudes toward traditional role models as explanatory approaches. In addition, acceptance of rape myths was considered. The GLMM analyses suggest that victim blaming by male subjects was significantly higher on average than by female subjects when all other predictors were held constant. As an explanatory approach for these effects of the subjects' gender on victim blaming, partial mediation was found with the degree of identification with the victim as a mediator. No main effects were found for the other influencing factors, but only a statistically significant three-way interaction. This indicates a differential effect of the level of stereotyping for male and female victims in conditions that end in high threat. The finding of the main effect of subjects' gender seems to be particularly important for the legal system, as it appears to make a difference in who is asked in terms of victim blameworthiness. This finding highlights the importance of considering a victim's personal characteristics and the need for future research with an additional focus on the characteristics of the sentencers to help clarify potential biases.

Previous research suggests that bystanders of conflicts use a range of intervention strategies. Yet, much less is known about other actions-beyond intervention-that bystanders might engage in during conflicts. Further, while prior studies reveal that gender differences emerge in bystander behavior, few studies have assessed the ecological validity of such potential differences in bystander actions during real-life conflicts. Addressing this concern, we systematically observed the diverse bystander behaviors of individuals presenting as men and women in real-life public conflicts captured on CCTV. We observed 67 public conflicts in the inner city of Amsterdam, the Netherlands. Using a qualitative approach, we first identified the broad spectrum of actions that bystanders engaged in. We then ran linear probability models to examine the relationship between bystander's gender presentation and bystanders' engagement in seven bystander actions (N = 1,959), followed by a multimodel analysis to test the robustness of these findings. Results indicate that bystanders engaged in a diversity of actions, ranging from inattentive (i.e., glancing while moving) and reactive actions (e.g., laughing) to physical forms of intervention. Unexpectedly, women were not more likely to engage in affiliative forms of intervention (e.g., calming hand gestures, non-forceful touching, and practical help). In addition to physical intervention, men were more likely to react to conflicts by laughing, filming, or cheering. The only type of action that was more typical among women than men was inattention (i.e., glancing while moving). Our results show that bystander behavior in public space is carried out in gendered ways, albeit in a less clear-cut manner than expected.

It is well known that sexual violence is a prevalent social problem that often results in numerous deleterious outcomes for victims and these outcomes are often influenced by rape acknowledgment (i.e., whether the rape victim acknowledges their experience as rape). Most research on rape acknowledgment examines acknowledgment as a dichotomous variable and comprises heterosexual cisgender women, revealing two gaps in the literature. To fill these gaps, this study used quantitative data that oversampled LGBTQ+ populations to examine three categories of rape acknowledgment (yes, no, uncertain) among a gender and sexually diverse sample (N = 817). Results indicate that 20% of the sample were uncertain as to whether they had been raped, 33% were unacknowledged victims, and 44% acknowledged their rape. Sexual minority transgender/nonbinary people had the highest prevalence of rape acknowledgment (56%), compared with four other groupings: heterosexual cis men and women as well as sexual minority cis men and women (28%-49%). Multivariate analysis revealed that when controlling for other factors, gender identity, but not sexual orientation, significantly predicts rape acknowledgment. Namely, sexual minority transgender/nonbinary people and cis women were more likely than cis men to acknowledge their rape. This study offers evidence to suggest that acknowledgment differs significantly by gender identity and is worth further inquiry. Limitations and suggestions for future research are discussed.

There are many commonalities between the clinical symptoms of dementia with Lewy bodies (DLB) and those of Alzheimer's disease (AD). The accurate differentiation of these two diseases is an important neuropsychological issue. The Mini-Mental State Examination (MMSE) is often used as a screening test for dementing disorders. We created evaluation items for the pentagon copy test of MMSE and developed a simple, highly accurate evaluation method for differentiating DLB in combination with conventional evaluation items such as the Qualitative Scoring MMSE Pentagon Test (QSPT). Subjects were divided into three groups: DLB (n = 119), AD (n = 50), and Normal (n = 26). The severities of DLB and AD ranged from mild cognitive impairment (MCI) to mild dementia. We compared the results of the pentagon copy test. We found that the rates of patients with abnormalities in "motor incoordination" and "gestalt destruction" were higher in the DLB group than the AD group. Furthermore, receiver operating characteristic curve analysis suggested the differentiation of DLB with high accuracy (sensitivity: 0.70, specificity: 0.78) using the criterion of patients meeting one of the following three characteristics: "the number of angles on QSPT: scores other than 4," "major tremor (Parkinsonism-related tremor) is present," and "gestalt destruction (distortion in overall coherence) is present." This evaluation method may be clinically useful for evaluating MCI to mild DLB patients because the burden on patients is low.

The present study focused on the emotional experience of anger among individuals with and without social anxiety disorder (SAD). Eighty-eight participants took part in the study, half (n = 44) met diagnostic criteria for SAD and half (n = 44) did not meet criteria for SAD. Participants completed a 21-day experience sampling measurement (ESM) in which they reported on daily social interactions and emotions. Using multilevel linear modeling we found that individuals with SAD experienced more anger compared to individuals without SAD. We also found a Diagnosis × Social Context interaction such that interactions with distant others were associated with elevated anger compared to interactions with close others for individuals with SAD but not for individuals without SAD. Finally, we found that for individuals with SAD (but not those without SAD) anger on a given day (day t) was associated with elevated anxiety on the following day (day t + 1), above and beyond previous anxiety, sadness and guilt (i.e. anxiety, sadness and guilt reported on day t). This suggests that anger may play a unique role in maintaining or exacerbating anxiety among individuals with SAD. Additional implications of our findings for models of psychopathology and for treatment of SAD are discussed.

Written exposure therapy (WET) is a five-session exposure-based protocol for treating post-traumatic stress disorder (PTSD). The brevity and tolerability of WET present the potential to overcome barriers in implementing evidence-based therapy for PTSD within the Korean mental healthcare system. This study investigated the effectiveness of WET in Korean patients with PTSD through a waitlist-controlled trial (KCT0008112). A total of 57 patients with PTSD were allocated non-randomly to either WET (n = 27) or treatment-as-usual waitlist groups (n = 30). Both groups were followed up until the twenty-fourth week after the initial session. Primary outcomes assessed included PTSD symptoms, depressive symptoms, and general function. In the WET group, significant improvements were observed in PTSD symptoms, depressive symptoms, and general function compared to the control group. After the waiting period, the waitlist group also participated in WET, and exhibited significant improvement in all scores. The between- and within-group effect sizes were large. The dropout rate in both groups was 10.9%, and the mean satisfaction ratings were 28.24 ± 3.33 (range 22-32; scale range 8-32). The present study provides evidence of WET successfully reducing PTSD and depressive symptoms and improving general function among Korean patients with PTSD. Moreover, WET was well tolerated and received by Korean patients with PTSD.

Academic AbstractProminent theories of belief and metacognition make different predictions about how people evaluate their biased beliefs. These predictions reflect different assumptions about (a) people's conscious belief regulation goals and (b) the mechanisms and constraints underlying belief change. I argue that people exhibit heterogeneity in how they evaluate their biased beliefs. Sometimes people are blind to their biases, sometimes people acknowledge and condone them, and sometimes people resent them. The observation that people adopt a variety of "metacognitive positions" toward their beliefs provides insight into people's belief regulation goals as well as insight into way that belief formation is free and constrained. The way that people relate to their beliefs illuminates why they hold those beliefs. Identifying how someone thinks about their belief is useful for changing their mind.Public AbstractThe same belief can be alternatively thought of as rational, careful, unfortunate, or an act of faith. These beliefs about one's beliefs are called "metacognitive positions." I review evidence that people hold at least four different metacognitive positions. For each position, I discuss what kinds of cognitive processes generated belief and what role people's values and preferences played in belief formation. We can learn a lot about someone's belief based on how they relate to that belief. Learning how someone relates to their belief is useful for identifying the best ways to try to change their mind.

In several highly publicized hearings, Dr. Christine Blasey Ford and Judge Brett Kavanaugh presented two opposing accounts of an alleged sexual assault. In the wake of these proceedings, partisans appeared similarly divided in how they regarded this political event. Using a U.S. national sample (N = 2,474) and a mixed-methods design, we investigated partisans' perceptions of, and responses to, the Ford-Kavanaugh hearings. Respondents reported their views of the hearings soon after they occurred. We used topic modeling to analyze these open-ended responses and found uniquely partisan topics emerged, including judicial impartiality and due process. Acute stress (AS) responses to the hearings were also related to partisan identities and perceptions; both Republicans (incidence rate ratio [IRR] = 0.81, 95% confidence interval [CI] = [0.78, 0.84]) and individuals who wrote more about Republican topics (IRR = 0.72, 95% CI = [0.56, 0.92]) reported lower AS than their Democratic counterparts. Results demonstrate different partisan perceptions with implications for mental health outcomes.

Background: Patients with extensive left hemisphere damage frequently have ideational apraxia (IA) and transcortical sensory aphasia (TSA). Difficulty with action coordination, phonological processing, and complex motor planning may not be indicative of higher-order motor programming or higher-order complex formation. We report on the effects of IA and TSA on the visual and motor skill of stroke patients.

Purpose: The study aims to address the question of whether IA and TSA in bilingual individuals are the results of an error of motor function alone or due to a combined motor plus and cognitive dysfunction effect.

Method: Twelve bilingual patients (seven males, and five females) were diagnosed with IA and TSA, and are divided into two groups of six patients. Then, 12 healthy bilingual controls were evaluated for comparing with both groups. Bilingual aphasia testing (BAT) and appropriate behavioral evaluation were used to assess motor skills, including coordination, visual-motor testing, and phonological processing.

Results: Findings (pointing skills) show that the performance of the L1 and L2 languages are consistently significant (p < 0.001) in healthy individuals compared to the IA and TSA groups. Command skills for L1 and L2 languages were significantly higher in healthy individuals compared to IA and TSA controls (p < 0.001). Further, the orthographic skills of IA and TSA vs controls in both groups were significantly reduced (p < 0.01). Visual skills in the L1 language were significantly improved (p < 0.05) in IA and TSA patients compared to healthy controls after 2 months. Unlike orthographic skills which were improved in IA and TSA patients, languages in bilingual patients did not simultaneously improve.

Conclusion: Dyspraxia is a condition that affects both motor and visual cognitive functions, and patients who have it often have less referred motor skills. The current dataset shows that accurate visual cognition requires both cognitive-linguistic and sensory-motor processes. Motor issues should be highlighted, and skills and functionality should be reinforced along with the significance of treatment between IA and TSA corresponding to age and education. This can be a good indicator for treating semantic disorders.

The Wechsler Memory Scale-I was published in 1945, although it had been used clinically since 1940. Since the original publication, there have been three major revisions. The Wechsler Memory Scale-Revised was published in 1987, the Wechsler Memory Scale-III in 1997, and the Wechsler Memory Scale-IV in 2009. It is significant to note that all official versions of the memory scale have remained in clinical and research use well into the second decade of the 20th century. Each version of the scale was designed to assess memory and attention dysfunction in various clinical populations by comparing the discrepancy between intelligence and memory test performance using age-corrected standard scores. It has long been known that intellectual and memory performance declines with age. Most psychologists, however, are likely unaware of the extent of the decline with age or how this decline is manifested in the various versions of the Wechsler Memory Scale. The purpose of this paper is to investigate what selected norms accompanying each official version of the Wechsler Memory Scale reveal about aging and memory performance and discuss the possible clinical implications of such.
