PROMPTED VOIDING TO REDUCE INCONTINENCE IN COMMUNITY-DWELLING OLDER ADULTS

In-home caregivers were taught to implement a prompted voiding procedure with 2 older adults with cognitive impairments and urinary incontinence. Results suggested that the procedures can be implemented by family caregivers, and the intervention reduced incontinence for both participants.     

"Don't try this at home": toddlers' imitation of new skills from people on video

Imitation of people on educational television is a potential way for very young children to learn new skills. Although toddlers in previous studies exhibited a “video deficit” in learning, 24-month-olds in Study 1 successfully reproduced behaviors modeled by a person who was on video as well as they did those modeled by a person who was present in the room (even after a 24-h delay). Neither displaced filming context nor cuts between actions affected toddlers’ imitation from video. Shortening the demonstration in Study 2 affected imitation in the video condition but not in the live condition. In Study 3, 24-month-olds who viewed the original longer videos on their family TV screens (with which they had a viewing history) imitated significantly less than those who viewed the videos on the laboratory monitor. Imitation of a live modeler was the same across settings (home or lab). Implications for toddlers’ judgments of reliable information sources and for the design of educational television programs are discussed.     

THE EFFECTS OF BEHAVIORAL SKILLS TRAINING ON CAREGIVER IMPLEMENTATION OF GUIDED COMPLIANCE

The effectiveness of a behavioral skills training package that consisted of modeling, rehearsal, and feedback was evaluated to increase correct implementation of guided compliance by caregivers of 3 children who exhibited noncompliance. Results showed that the training package improved performance of guided compliance. Generalization probes indicated that the skills learned were exhibited in different settings 3 to 6 weeks after training ended.     

Sex, Lies, and Video Games: The Portrayal of Male and Female Characters on Video Game Covers

Two hundred twenty-five console video game covers obtained from online retail sites were examined for portrayals of men and women. We hypothesized that males would be portrayed more often, but that females would be portrayed in a more hyper-sexualized manner. Male characters were almost four times more frequently portrayed than female characters and were given significantly more game relevant action. However, in spite of their less frequent appearance, female characters were more likely to be portrayed with exaggerated, and often objectified, sexiness. Further, violence and sexiness was paired more frequently for female characters than violence and muscular physiques for the male characters. The potential influence these negative portrayals could have on gamers is discussed.     

Enhancing early communication through infant sign training

Existing research suggests that there may be benefits to teaching signing to hearing infants who have not yet developed vocal communication. In the current study, each of 4 infants ranging in age from 6 to 10 months was taught a simple sign using delayed prompting and reinforcement. In addition, Experiment 1 showed that 2 children independently signed in a variety of novel stimulus conditions (e.g., in a classroom, with father) after participating in sign training under controlled experimental conditions. In Experiment 2, crying and whining were replaced with signing when sign training was implemented in combination with extinction.     

Evaluation of a Video Prompting and Fading Procedure for Teaching Dish Washing Skills to Adults with Developmental Disabilities

We evaluated a video prompting and fading procedure for teaching three adults with developmental disabilities to wash dishes. Video prompting involved showing video clips depicting each step of the task. All three adults reached 90–100% correct when video prompting was implemented. Following acquisition, video prompting was withdrawn, but performance deteriorated. Subsequently, a 3-step fading procedure was implemented in which the separate video clips were merged to form larger, multi-step segments of video. Performance reached 80–100% correct as the video prompts were re-applied and then faded. Performance decreased at the 3-month follow-up when prompting was removed, but stabilized at 80–90% correct when the third step in the fading sequence was reinstated. These data suggest a promising approach for fading video prompts.     

Gaming magazines and the drive for muscularity in preadolescent boys: a longitudinal examination

The development of a drive for muscularity among boys has been linked to various cultural influences, one of which is exposure to mass media depicting the muscular male body ideal. We sought to determine whether self-reported exposure to four ideal-body magazine genres (health/fitness, fashion, sports, and gaming) predicted an increased drive for muscularity 1 year later. A sample of 104 Black and 77 White preadolescent boys (mean age 8.77) participated in a 2-wave longitudinal panel study. Controlling Wave 1 grade, perceived thinness/adiposity, and drive for muscularity, exposure to video gaming magazines predicted a significant increase in Wave 2 drive for muscularity, but only for White boys. Discussion calls for the inclusion of video gaming magazine exposure measures in future research on print media and male body ideals, along with empirical exploration of racial themes in gaming magazines.     

亲社会性视频游戏对内隐攻击性认知抑制效应的实验

利用亲社会性视频游戏和IAT测验,从内隐社会认知的角度研究亲社会性视频游戏对高中生内隐攻击性认知的影响,并分析影响是否具有性别差异和攻击特质差异。结果表明:(1)亲社会性视频游戏对高中生内隐攻击性认知的抑制效应显著;(2)游戏类型和性别对内隐攻击性认知的交互作用显著,亲社会性视频游戏更容易对女生的内隐攻击性认知产生抑制效应;(3)攻击特质对高中生的内隐攻击性认知的主效应显著,并且游戏类型和攻击特质对高中生内隐攻击性认知的交互作用显著,亲社会性视频游戏更容易对低攻击特质学生产生抑制效应。由此可见,亲社会性视频游戏能够有效抑制高中生的内隐攻击性认知水平。     

An evaluation of speed management measures in Bangladesh based upon alternative accident recording,speed measurements,and DOCTOR traffic conflict observations

With 21,000 people annually killed in road traffic (estimated figure by World Health Organization), Bangladesh has one of the highest fatality rates in the world. Vulnerable road users (VRUs) account for over 50% of road traffic casualties, and 70% of casualties occur in rural areas. As in many Low and Middle Income Countries (LMICs), the official road accident statistics are incomplete and biased.Safe Crossings (Netherlands) and the Centre for Injury Prevention and Research Bangladesh (CIPRB) (Bangladesh) received permission from the Bangladesh government in 2014 to design and implement an integrated speed management program (consisting of a combination of small-scale infrastructural measures, active community involvement and road user education) at three locations where a national highway intersects small communities. The infrastructural countermeasures to improve road safety consisted of speed humps, rumble strips, signs and road markings and were designed following the Dutch road design guidelines. In a Before–After study design, we used a combination of three research methods to monitor and evaluate the road safety interventions. We created our own traffic accident recording system with trained local record keepers, we conducted laser-gun speed measurements of motorized traffic (both at intervention and control locations), and we applied the Dutch Objective Conflict Technique for Operation and Research (DOCTOR) for observing serious traffic conflicts at the intervention locations. The latter was based upon DOCTOR scores from video recordings of the behaviour at the three experimental locations Before and After the interventions.Prior to installing the intervention program, the three locations combined had, on average, about 100 serious accidents, 10 deaths, and 200 injured people on a yearly basis. In April 2015, all infrastructural measures were completed. In the after period (till the end of January 2016), the alternative accident recording system showed a 66% reduction in the number of serious accidents, a 73% reduction in the number of injured people, and a 67% reduction in the number of people killed.The unobtrusive laser-gun speed measurements resulted in a net reduction of 13.3 km/h (or 20% in relative terms) on average at the intervention locations by taking the general speed development at the control locations into account. According to Nilsson’s power law this would result in a 59% reduction of the number of people killed, well in line with the actual accident figures.The total number of serious conflicts (only DOCTOR scores 3, 4, and 5) was significantly reduced from 64 serious conflicts per location in a 4.5 h period Before to 29 serious conflicts in the After period, on average (Poisson distributed variable, p < 0.01), or a 55% reduction in relative terms. By including the traffic volumes, the reduction in conflict risk overall is 54%. Moreover, the severity of conflicts was reduced in the After period with only one most severe conflict (DOCTOR score 5) left. Buses represent the largest portion of road users involved in serious conflicts at all three locations, followed by cars and CNGs (Compressed Natural Gas vehicle). By far, the most frequently occurring conflict is of the type head-on conflict between an overtaking bus or car that is encountering a road user in opposite direction (for the greater part a CNG).All three evaluation measures point to a similar impact of the intervention program and unveil an improvement in road safety between 54% and 60%. The speed-reducing measures indeed considerably reduce the speed of motorized traffic, both the mean speed and 85th percentile values, both the number and severity of serious conflicts are reduced, and the actual number of accidents has decreased. It appears that Nilsson’s power law for the relation between a difference in mean speed and the change in the number of accidents also applies to LMICs.Speed management measures as common in high-income countries appear to be also effective in LMICs. For evaluation purposes of road safety impacts, a Traffic Conflicts Technique approach (also developed in high-income countries) seems valid and effective as well for application in LMICs.As there are thousands of traffic black spots with similar characteristics as the three intervention locations in Bangladesh, this integrated approach may well offer similar road safety improvements elsewhere.     

The impact of physical load on duration estimation in sport

We investigated whether physical load has an influence on the accuracy of duration estimation of sporting activities presented in real time and slow motion. 86 participants were studied in two single sessions of 45 min each.Our results showed no general effects for physical load, when comparing physical load versus rest. However, we could replicate findings of past research (Schütz et al., 2021), showing that the duration of sports performance is estimated more accurately when presented in real time compared to slow motion. Further we found, that under physical load, participants perceiving the physical exercise as hard (RPE ≥15) estimated time significantly shorter and more accurately compared to participants perceiving the physical exercise as light or moderate (RPE <15).Thus, our results suggest that using slow motion may worsen the assessment of sports performance. Additionally, we could show that intense physical exertion contributes to reducing the overestimation of time.
