We explored the intergenerational transmission effects of maternal adverse childhood experiences (ACEs) and infant neglect from multiple perspectives. The study included a sample of postpartum mothers and infants (N = 550) from the outpatient child health care department of a tertiary hospital in Jinan, Shandong Province, China. Our investigation followed three main lines of inquiry. First, the association of overall maternal ACEs with infant neglect was estimated. Secondly, the cumulative and independent effects of maternal ACEs on infant neglect were explored using the Adverse Childhood Experience Questionnaire-Revised (ACEQ-R) with 14 types of ACEs. Finally, the different patterns of 14 maternal ACEs were identified, and the association between the different patterns and infant neglect was explored. There were three main findings. First, infants born to mothers with ACEs experienced higher levels of neglect compared to those born to mothers without ACEs. Second, infants born to mothers with three or more subtypes of ACEs experienced the greatest levels of neglect, with maternal childhood physical neglect emerging as a particularly influential factor. Third, infants in the "median maternal ACEs" and "high maternal neglect and poor peer relationship" groups experienced more severe neglect than those in the "low maternal ACEs" group. These results suggest that early life experiences substantially shape future parenting behaviors, such as infant neglect.

Intimate partner or marital/spousal rape is a phenomenon with unique characteristics and dynamics. Furthermore, it is an under-explored, under-defined, under-reported, and widely tolerated phenomenon. Gender-based violence and intimate partner violence are the main topics of the present study. The study aimed at exploring the trends in reported intimate partner and marital/spousal rape, within the wider context of reported domestic violence during the years 2020 and 2021 in Greece. Statistical analysis has not indicated positive correlation between the rate of reported domestic violence per year and the rate of reported domestic rape per year, with the former following an upward trend and the latter maintaining an almost steady course. Similarly, the rate of reported victims of intimate partner rape per year remained almost stable within in the 2 years. Importantly however, in 2021, the rate of reported victims of marital rape per year increased remarkably compared to 2020. In 2021, the rates of reported domestic violence per month and reported domestic rape per month indicated remarkable increase over the period May to December 2021. Notwithstanding, the rates mentioned above remained almost stable over the year 2020, showing an upward trend during the summer months. In August 2020 and 2021 the abovementioned rates reached their peak. In both years, the vast majority of victims of domestic rape were females, mostly between 30 and 45 years of age. The present study indicated an increase in rates of reported domestic violence and reported domestic rape per month after the lockdowns, especially after the second long-lasting lockdown that ended in May 2021. This increase, however, might be only apparent. Further research is needed to study the epidemiology of intimate partner and marital rape over a much longer timespan to provide further insight into the dynamics surrounding a public health concern.

Objective: In usability studies, the subjective component of usability, perceived usability, is often of interest besides the objective usability components, efficiency and effectiveness. Perceived usability is typically investigated using questionnaires. Our goal was to assess experimentally which of four perceived-usability questionnaires differing in length best reflects the difference in perceived usability between systems.

Background: Conventional measurement wisdom strongly favors multi-item questionnaires, as measures based on more items supposedly yield better results. However, this assumption is controversial. Single-item questionnaires also have distinct advantages and it has been shown repeatedly that single-item measures can be viable alternatives to multi-item measures.

Method: N = 1089 (Experiment 1) and N = 1095 (Experiment 2) participants rated the perceived usability of a good or a poor web-based mobile phone contract system using the 35-item ISONORM 9241/10 (Experiment 1 only), the 10-item System Usability Scale (SUS), the 4-item Usability Metric for User Experience (UMUX), and the single-item Adjective Rating Scale.

Results: The Adjective Rating Scale represented the perceived-usability difference between both systems at least as good as, or significantly better than, the multi-item questionnaires (significantly better than the UMUX and the ISONORM 9241/10 in Experiment 1, significantly better than the SUS in Experiment 2).

Conclusion: The single-item Adjective Rating Scale is a viable alternative to multi-item perceived-usability questionnaires.

Application: Extremely short instruments can be recommended to measure perceived usability, at least for simple user interfaces that can be considered concrete-singular in the sense that raters understand which entity is being rated and what is being rated is reasonably homogenous.

Objective: The counterintuitive "Union Jack"-inspired turn signals on versions of BMW's Mini vehicles was investigated to reveal potential impacts on human performance.

Background: When some Mini drivers indicate a change in direction, they do so with an oppositely oriented arrow. This conflict, between the task-irrelevant spatial shape and task-relevant location of the signal, mimics a "converse" spatial-Stroop effect that, in combination with the ubiquitous use of arrows on road signs, may be confusing.

Method: Participants (n = 30) responded-via right and left keypresses-to the directions of road signs and turn signals in both pure and mixed blocks. Reaction times and accuracies were recorded to determine performance in each condition (compatible, neutral, incompatible).

Results: Performance suffered when the location and direction of the stimuli did not correspond. When responding to turn signals the cost to performance was especially salient in mixed blocks. Thus, when driving on roads where the meanings of arrows on road signs is important, turn signals pointing in a direction opposite from the directional intention indicated by the signals' location are likely to be confusing.

Conclusion: The design of some Mini's "Union Jack" style taillights opposes well-established principles of cognitive functioning, caused confusion in our laboratory study and therefore may be a safety hazard-a possibility that ought to be explored in more realistic (e.g., driving simulator) situations.

Application: BMW designers should consider universally adopting the neutral, "horizontal line," illumination style that is currently available in the aftermarket.

Previous research shows that large, densely populated urban areas have higher rates of child victimization that have persisted over time. However, few investigations have inquired about the processes that produce and sustain hot and cold spots of child victimization. As a result, the mechanisms that produce the observed spatial clustering of child victimization, and hence "why" harms against children tend to cluster in space, remains unknown. Does the likelihood of being a victim of violence in one location depend on a similar event happening in a nearby location within a specified timeframe? Rather, are child victims of violence more likely to reside in suboptimal neighborhood conditions? This paper aims to present an analytical and theoretical framework for distinguishing between these locational (point) processes to determine whether the empirical spatial patterns undergirding child victimization are more reflective of the "spread" via contagion (i.e., dependency) or whether they are produced by neighborhood structural inequality resulting from spatial heterogeneity. To detect spatial dependence, we applied the inhomogeneous K-function to Los Angeles Medical Examiner data on child homicide victim locations while controlling for regional differences in victimization events (i.e., heterogeneity). Our analysis found strong evidence of spatial clustering in child victimization at small spatial scales but inhibition at larger scales. We further found limited support for the spatiotemporal clustering of child victimization indicative of a contagion effect. Overall, our results support the role of neighborhood structural vulnerability in the underlying mechanisms producing patterns of child victimization across Los Angeles County. We conclude by discussing the policy implications for understanding this spatial patterning in geographical context and for developing effective and targeted preventive interventions.

Objective: Examine patterns and predictors of skill learning during multisession Enhanced FOrward Concentration and Attention Learning (FOCAL+) training.

Background: FOCAL+ teaches teens to reduce the duration of off-road glances using real-time error learning. In a randomized controlled trial, teens with ADHD received five sessions of FOCAL+ training and demonstrated significant reductions in extended glances (>2-s) away from the roadway (i.e., long-glances) and a 40% reduced risk of a crash/near-crash event. Teens' improvement in limiting long-glances as assessed after each FOCAL+ training session has not been examined.

Method: Licensed teen (ages 16-19) drivers with ADHD (n = 152) were randomly assigned to five sessions of either FOCAL+ or modified standard driver training. Teens completed driving simulation assessments at baseline, after each training session, and 1 month and 6 months posttraining. Naturalistic driving was monitored for one year.

Results: FOCAL+ training produced a 53% maximal reduction in long-glances during postsession simulated driving. The number of sessions needed to achieve maximum performance varied across participants. However, after five FOCAL+ training sessions, number of long-glances was comparable irrespective of when teens achieved their maximum performance. The magnitude of reduction in long-glances predicted levels of long-glances during simulated driving at 1 month and 6 months posttraining but not naturalistic driving outcomes. FOCAL+ training provided the most benefit during training to teens who were younger and had less driving experience.

Conclusion: FOCAL+ training significantly reduces long-glances beginning at the 1st training session.

Application: Providing five FOCAL+ training sessions early on during teen driving may maximize benefit.

Objective: We examined whether active head aiming with a Helmet Mounted Display (HMD) can draw the pilot's attention away from a primary flight task. Furthermore, we examined whether visual clutter increases this effect.

Background: Head up display symbology can result in attentional tunneling, and clutter makes it difficult to identify objects.

Method: Eighteen military pilots had to simultaneously perform an attitude control task while flying in clouds and a head aiming task in a fixed-base flight simulator. The former consisted of manual compensation for roll disturbances of the aircraft, while the latter consisted of keeping a moving visual target inside a small or large head-referenced circle. A "no head aiming" condition served as a baseline. Furthermore, all conditions were performed with or without visual clutter.

Results: Head aiming led to deterioration of the attitude control task performance and an increase of the amount of roll-reversal errors (RREs). This was even the case when head aiming required minimal effort. Head aiming accuracy was significantly lower when the roll disturbances in the attitude control task were large compared to when they were small. Visual clutter had no effect on both tasks.

Conclusion: We suggest that active head aiming of HMD symbology can cause attentional tunneling, as expressed by an increased number of RREs and less accuracy on a simultaneously performed attitude control task.

Application: This study improves our understanding in the perceptual and cognitive effects of (military) HMDs, and has implications for operational use and possibly (re)design of HMDs.

Many individuals with intellectual and developmental disabilities (DD) encounter difficulties in performing daily living skills, which limits their self-sufficiency and autonomy. Caregivers, such as parents, are often the individuals who interact with individuals with DD the most during daily living skills routines. Therefore, it is critical to teach caregivers to implement daily living skills interventions with their children. A systematic review of the literature related to caregiver-implemented daily living skills interventions yielded 38 articles. Of those, 20 articles, with 21 experiments, were rated as high quality based on What Works Clearinghouse design standards. Behavior skill training was the most common strategy used to teach caregivers to implement interventions. Common daily living skills interventions included prompting, reinforcement, and task analysis. The most common form of prompting was verbal prompting, and the most common schedule of reinforcement was a continuous schedule of reinforcement. Of the 21 high-quality experiments, 86% demonstrated caregiver-implemented interventions yielded improvements in daily living skills. Several studies demonstrated generalization and maintenance of daily living skills. Implications for research and practice are discussed.

Objective: To evaluate a personalized adaptive training program designed for stress prevention using graduated stress exposure.

Background: Astronauts in the high-risk space mission environment are prone to performance-impairing stress responses, making preemptive stress inoculation essential for their training.

Methods: This work developed an adaptive virtual reality-based system that adjusts environmental stressors based on real-time stress indicators to optimize training stress levels. Sixty-five healthy subjects underwent task training in one of three groups: skill-only (no stressors), fixed-graduated (prescheduled stressor changes), and adaptive. Psychological (subjective stress, task engagement, distress, worry, anxiety, and workload) and physiological (heart rate, heart rate variability, blood pressure, and electrodermal activity) responses were measured.

Results: The adaptive condition showed a significant decrease in heart rate and a decreasing trend in heart rate variability ratio, with no changes in the other training conditions. Distress showed a decreasing trend for the graduated and adaptive conditions. Task engagement showed a significant increase for adaptive and a significant decrease for the graduated condition. All training conditions showed a significant decrease in worry and anxiety and a significant increase in the other heart rate variability metrics.

Conclusion: Although all training conditions mitigated some stress, the preponderance of trial effects for the adaptive condition supports that it is more successful at decreasing stress.

Application: The integration of real-time personalized stress exposure within a VR-based training program not only prepares individuals for high-stress situations by preemptively mitigating stress but also customizes stressor levels to the crew member's current state, potentially enhancing resilience to future stressors.

Being trans is stigmatized and can make it difficult to fit into the job market in South Korean society. This study explored trans individuals' job-seeking experience and the impact of gender identity on their career choices and development using a qualitative approach. In-depth interviews were conducted with 20 trans adults with job-seeking experiences who were recruited through purposive and snowball sampling in South Korea. Ten subthemes were identified in three overarching themes: (a) limiting myself in job search; (b) challenges in the job application and interview process; and (c) having a desire to build a meaningful career. Participants limited their choices for employment in favor of gender-neutral jobs or trans-inclusive work environments. In the job-seeking process, they faced challenges due to society's rigid binary gender roles and the negative stereotypes about trans identities. Despite stress and identity-related conflict, participants expressed a desire to overcome challenges, build a meaningful career, and flourish at work without compromising their gender identity. This study highlights the experiences of trans individuals in their job-seeking journey. Psychosocial interventions and career support services could help trans individuals in the job-seeking process by identifying their unique challenges to employment and providing assistance to cope with stigma and oppression.
