Training flexible spatial-cognitive estimation strategies using augmented reality.

We investigated the potential for augmented reality (AR) as a training aid for spatial estimation skills. Though there are many tools to support spatial judgments, from measuring cups to rulers, not much is known about training spatial skills for retention and transfer. Display of AR was manipulated to train the spatial skill of portion estimation. In Experiment 1, an AR-aided strategy of creating smaller portions out of a larger example amount was compared to a no-AR control condition. This manipulation was based on previous non-AR experiments where amorphous foods were better estimated when divided into smaller portions. There was a significant benefit of estimating using a solid AR shape. In Experiment 2, cognitive anchoring was manipulated. Using meaningful AR anchors resulted in the best performance and most learning. We conclude that spatial estimation skills can be combined with mental strategies and trained via AR.

Various methods of providing augmented reality reference images were compared in the training of spatial estimation skills. Findings using AR reference images differed from previous research on portion estimation and providing solid, meaningful images resulted in the best performance and learning, as measured via retention and transfer.

The Relevance of Attention Control, Not Working Memory, in Human Factors.

OBJECTIVE: Discuss the human factors relevance of attention control (AC), a domain-general ability to regulate information processing functions in the service of goal-directed behavior. BACKGROUND: Working memory (WM) measures appear as predictors in various applied psychology studies. However, measures of WM reflect a mixture of memory storage and controlled attention making it difficult to interpret the meaning of significant WM-task relations for human factors. In light of new research, complex task performance may be better predicted or explained with new measures of attention control rather than WM. METHOD: We briefly review the topic of individual differences in abilities in Human Factors. Next, we focus on WM, how it is measured, and what can be inferred from significant WM-task relations. RESULTS: The theoretical underpinnings of attention control as a high-level factor that affects complex thought and behavior make it useful in human factors, which often study performance in complex and dynamic task environments. To facilitate research on attention control in applied settings, we discuss a validated measure of attention control that predicts more variance in complex task performance than WM. In contrast to existing measures of WM or AC, our measures of attention control only require 3 minutes each (10 minutes total) and may be less culture-bound making them suitable for use in applied settings. CONCLUSION: Explaining or predicting task performance relations with attention control rather than WM may have dramatically different implications for designing more specific, equitable task interfaces, or training. APPLICATION: A highly efficient ability predictor can help researchers and practitioners better understand task requirements for human factors interventions or performance prediction.

Acceptability of RealConsent: A Sexual Violence Web-Based Risk Reduction Program for College Women.

Acceptability of a sexual violence (SV) risk reduction program called RealConsent designed for first-year female college students was conducted as part of a larger, randomized controlled trial. RealConsent uses web-based and mobile technology to deliver four 45-minute theoretically and empirically derived modules designed to increase knowledge, affect attitudes and normative beliefs, increase bystander and other protective behaviors, and reduce alcohol misuse. Educational entertainment is used throughout the program to achieve these aims. A total of 444 first-year female college students recruited from three Southeastern universities who were eligible and provided informed consent were randomized to RealConsent. Acceptability was ascertained both quantitatively and qualitatively through a survey administered following the completion of each of four modules. Results suggest that overall, RealConsent was viewed as relatable, realistic, and relevant. Most participants rated modules as good/excellent in quality, in organization, and in the conveying of a high degree of knowledge regarding alcohol misuse, consent for sex, sexual communication, defense strategies, protective strategies, and intervening to prevent SV. Suggestions to improve RealConsent centered on having more content inclusive of sexual and gender-minoritized students. Results suggest that RealConsent is an acceptable SV risk reduction program among first-year female college students and may have advantages for dissemination over in-person programs due to its web-based and mobile technology.

Advancing a Comprehensive Multilevel Approach to Sexual Violence Prevention Using Existing Efficacious Programs.

ABSTRACT: Sexual violence (SV) is a serious and long-standing public health problem on college campuses. At institutions of higher education, campus administrators, activists, and practitioners have worked for decades to address campus SV. Despite federally mandated campus SV prevention programming, rates of campus SV remain unchanged. The purpose of this commentary is to outline a strategy for enhancing campus SV prevention efforts using a comprehensive multilevel approach utilizing existing efficacious programs. The following three strategies for implementing optimal campus SV prevention are proposed, which include (a) the need to prioritize efficacy, (b) targeting multiple levels of the social ecology, and (c) leveraging the benefits of in-person programming and technology-driven prevention. A call to action is included for both institutions of higher education administrators and practitioners to implement and invest in comprehensive multilevel interventions using existing, efficacious SV programs, ideally combining a technology-based program with an in-person component. Furthermore, a coordinated effort between prevention and response is needed to achieve successful prevention of campus SV and revictimization, including a connection with the community for postassault interventions. Thus, implementing multilevel interventions on college campuses using existing evidence-based programs in combination with a coordinated community response of postassault interventions can bring the campus community together and is optimal to moving the needle on rates of campus SV.

Study protocol for a randomized controlled trial of RealConsent2.0: a web-based intervention to promote prosocial alcohol-involved bystander behavior in young men.

BACKGROUND: Sexual violence (SV) is a significant, global public health problem, particularly among young adults. Promising interventions exist, including prosocial bystander intervention programs that train bystanders to intervene in situations at-risk for SV. However, these programs suffer from critical weaknesses: (1) they do not address the proximal effect of alcohol use on bystander decision-making and (2) they rely on self-report measures to evaluate outcomes. To overcome these limitations, we integrate new content specific to alcohol use within the context of prosocial bystander intervention into an existing, evidence-based program, RealConsent1.0. The resulting program, RealConsent2.0, aims to facilitate bystander behavior among sober and intoxicated bystanders and uses a virtual reality (VR) environment to assess bystander behavior in the context of acute alcohol use. METHODS: This protocol paper presents the design of a randomized controlled trial (RCT) in which we evaluate RealConsent2.0 for efficacy in increasing alcohol- and non-alcohol-involved bystander behavior compared to RealConsent1.0 or to an attention-control program ("Taking Charge"). The RCT is being implemented in Atlanta, GA, and Lincoln, NE. Participants will be 605, healthy men aged 21-25 years recruited through social media, community-based flyers, and university email lists. Eligible participants who provide informed consent and complete the baseline survey, which includes self-reported bystander behavior, are then randomized to one of six conditions: RealConsent2.0/alcohol, RealConsent2.0/placebo, RealConsent1.0/alcohol, RealConsent1.0/placebo, Taking Charge/alcohol, or Taking Charge/placebo. After completing their assigned program, participants complete a laboratory session in which they consume an alcohol (target BrAC: .08%) or placebo beverage and then engage in the Bystanders in Sexual Assault Virtual Environments (BSAVE), a virtual house party comprising situations in which participants have opportunities to intervene. Self-reported bystander behavior across alcohol and non-alcohol contexts is also assessed at 6- and 12-months post-intervention. Secondary outcomes include attitudes toward, outcome expectancies for, and self-efficacy for bystander behavior via self-report. DISCUSSION: RealConsent2.0 is the first web-based intervention for young men that encourages and teaches skills to engage in prosocial bystander behavior to prevent SV while intoxicated. This is also the first study to assess the proximal effect of alcohol on bystander behavior via a VR environment. TRIAL REGISTRATION: Clinicaltrials.gov, NCT04912492. Registered on 05 February 2021.

Hey ChatGPT, Let's Talk About Sexual Consent.

Access to sexual health education, such as education on sexual consent, is limited in the US. Artificial intelligence (AI), such as ChatGPT, provides a potential opportunity to increase access to sexual consent information and education. However, what ChatGPT knows about sexual consent and if this aligns with the current evidence-based literature on sexual consent is unclear. The goal of this research commentary was to explore what ChatGPT knows about sexual consent with a focus on: 1) the definition of consent, 2) how consent could be communicated, and 3) the impact that substances have on consent. We also examined the reliability of ChatGPT's responses by having three different researchers ask ChatGPT the same set of questions. Across our questions, ChatGPT provided similar and comprehensive responses that discussed key features of consent - that consent is freely given or reversible. ChatGPT provided examples of different verbal and nonverbal cues people can use to communicate and interpret consent and discussed the ways that substances can impact consent communication. Overall, ChatGPT could be a potential resource for educators and young people who seek information about sexual consent; however, we should proceed with caution. ChatGPT is not a replacement for an educator but rather a way to increase access to education.

A Web-Based Sexual Violence, Alcohol Misuse, and Bystander Intervention Program for College Women (RealConsent): Randomized Controlled Trial.

BACKGROUND: Sexual violence (SV) incidence among college women has been invariant for the past 20 years. Innovative prevention strategies that are low resource and technology driven but demonstrate efficacy are greatly needed. OBJECTIVE: The aim of this study was to determine the efficacy of a novel theoretically driven internet-based intervention for first-year college students who identify as women (RealConsent) in reducing their risk of exposure to SV and alcohol misuse as well as increasing alcohol protective and bystander behaviors. METHODS: This randomized controlled trial involved first-year college students who identified as women (n=881) attending 1 of 3 universities in the southeastern United States. Participants aged 18 to 20 years were randomized to RealConsent (444/881, 50.4%) or to an attention-matched placebo control (437/881, 49.6%). RealConsent is fully automated and consists of four 45-minute modules that incorporate entertainment-education media and proven behavior change techniques. The primary outcome was exposure to SV; the secondary outcomes were alcohol protective behaviors, dating risk behaviors, alcohol misuse, and bystander behavior. Study outcomes were assessed at baseline and 6-month follow-up. RESULTS: Among participants with some exposure to SV, those in the RealConsent group experienced less exposure to SV than the placebo group (adjusted incidence rate ratio 0.48, 95% CI 0.33-0.69; P=.002). Furthermore, participants in the RealConsent group engaged in more alcohol protective behaviors (adjusted odds ratio 1.17, 95% CI 0.12-2.22; P=.03) and were less likely to binge drink (adjusted incidence rate ratio 0.81, 95% CI 0.67-0.97; P=.003). Finally, participants in the RealConsent group who had 100% dosage were more likely to engage in bystander behavior than those with <100% dosage plus placebo group (adjusted odds ratio 1.72, 95% CI 1.17-2.55; P=.006). CONCLUSIONS: A comprehensive exposure to SV, alcohol use, and bystander educational program was successful in decreasing the occurrence of exposure to SV among those most at risk and in increasing alcohol protective behaviors. Because of its web-based and mobile technologies, RealConsent can be easily disseminated and holds potential for reducing campus SV.

Frequency of Visiting Alcohol-Serving Establishments, Bystander Efficacy, and Barriers to Sexual Aggression Bystander Intervention Among College Students.

Bystanders can play an important role in sexual aggression (SA) prevention, particularly those often present at bars and clubs where SA commonly occurs. Yet, more frequent patrons of bars and clubs may experience more barriers to intervening due to social norms that encourage aggression in these environments. Having greater confidence to intervene in SA may mitigate this relationship. This study examined these associations among 290 undergraduate students (Mage = 20.03; SDage = 20.03; 50% women) who completed measures of past semester bar and club attendance, bystander efficacy (i.e., confidence), and barriers to intervention. Moderation analyses using PROCESS indicated (1) a conditional main effect of bystander efficacy being associated with less failure to take intervention responsibility; (2) bar and club attendance was associated with less audience inhibition (i.e., failure to intervene due to concerns of looking foolish) among those higher (b = -0.30, p = 0.005), but not lower (b = 0.16, p = 0.183), in bystander efficacy. Bystander training programs should consider specifically targeting college students who attend bars and clubs more frequently, as they likely have more intervention opportunities, and provide them with skills to confidently intervene in SA while socializing in those settings.

Study protocol for the St James's Hospital, Tallaght University Hospital, Trinity College Dublin Allied Researchers' (STTAR) Bioresource for COVID-19.

Background: The current coronavirus disease 2019 (COVID-19) pandemic began in Ireland with the first confirmed positive case in March 2020. In the early stages of the pandemic clinicians and researchers in two affiliated Dublin hospitals identified the need for a COVID-19 biobanking initiative to support and enhance research into the disease. Through large scale analysis of clinical, regional, and genetic characteristics of COVID-19 patients, biobanks have helped identify, and so protect, at risk patient groups The STTAR Bioresource has been created to collect and store data and linked biological samples from patients with SARS-CoV-2 infection and healthy and disease controls. Aim: The primary objective of this study is to build a biobank, to understand the clinical characteristics and natural history of COVID-19 infection with the long-term goal of research into improved disease understanding, diagnostic tests and treatments. Methods: This is a prospective dual-site cohort study across two tertiary acute university teaching hospitals. Patients are recruited from inpatient wards or outpatient clinics. Patients with confirmed COVID-19 infection as well as healthy and specific disease control groups are recruited.  Biological samples are collected and a case report form detailing demographic and medical background is entered into the bespoke secure online Dendrite database. Impact: The results of this study will be used to inform national and international strategy on health service provision and disease management related to COVID-19. In common with other biobanks, study end points  evolve over time as new research questions emerge. They currently include patient survival, occurrence of severe complications of the disease or its therapy, occurrence of persistent symptoms following recovery from the acute illness and vaccine responses.

Diagnostic Performance of Xpert MTB/RIF Ultra Compared with Predecessor Test, Xpert MTB/RIF, in a Low TB Incidence Setting: a Retrospective Service Evaluation.

The aim of this study was to evaluate the performance of Xpert MTB/RIF Ultra (Ultra) compared with its predecessor, Xpert MTB/RIF (Xpert), in the diagnosis of tuberculosis (TB) in a low TB incidence country. Retrospective analysis was performed on 689 clinical samples received between 2015 and 2018, on which Xpert was performed, and on 715 samples, received between 2018 and 2020, on which Ultra was performed. Samples were pulmonary (n = 830) and extrapulmonary (n = 574) in nature, and a total of 264 were culture positive for Mycobacterium tuberculosis complex (MTBC). The diagnostic performance of both assays was analyzed using culture as the reference standard. The sensitivity of Ultra for culture positive (smear positive and smear negative) MTBC samples, was 93.2% (110/118) compared with 82.2% (120/146) for Xpert (P = 0.0078). In smear negative-culture positive samples, Ultra had a sensitivity of 74.2% (23/31) versus 36.11% (13/36) for Xpert (P = 0.0018). Specificity of both assays was comparable at 94.8% (566/597) for Ultra and 95.8% (520/543) for Xpert (P = 0.4475). The sensitivity of Ultra and Xpert assays among exclusively pulmonary samples was 95.3% (82/86) and 90.3% (84/93), respectively (P = 0.1955), and 87.5% (28/32) and 67.9% (36/53), respectively, among extrapulmonary samples (P = 0.0426). Ultra showed improved performance compared with Xpert in a low TB incidence setting, particularly in smear negative and extrapulmonary MTBC disease. The specificity of Ultra was lower than Xpert, however, this was not statistically significant. IMPORTANCE The study demonstrates the improved sensitivity of the Ultra compared with the Xpert, particularly in smear negative TB disease, for both pulmonary and extrapulmonary samples in a low TB incidence setting. Cycle threshold (Ct) value for both assays was found to positively correlate with time to TB culture positivity, suggesting that Ct and semiquantitative results could be used as indicators of sample MTBC bacillary burden, and thus, perhaps, of transmission potential. This may have implications for the designation of patient isolation precautions.

Severe COVID-19 is characterised by inflammation and immature myeloid cells early in disease progression.

SARS-CoV-2 infection causes a wide spectrum of disease severity. Identifying the immunological characteristics of severe disease and the risk factors for their development are important in the management of COVID-19. This study aimed to identify and rank clinical and immunological features associated with progression to severe COVID-19 in order to investigate an immunological signature of severe disease. One hundred and eight patients with positive SARS-CoV-2 PCR were recruited. Routine clinical and laboratory markers were measured, as well as myeloid and lymphoid whole-blood immunophenotyping and measurement of the pro-inflammatory cytokines IL-6 and soluble CD25. All analysis was carried out in a routine hospital diagnostic laboratory. Univariate analysis demonstrated that severe disease was most strongly associated with elevated CRP and IL-6, loss of DLA-DR expression on monocytes and CD10 expression on neutrophils. Unbiased machine learning demonstrated that these four features were strongly associated with severe disease, with an average prediction score for severe disease of 0.925. These results demonstrate that these four markers could be used to identify patients developing severe COVID-19 and allow timely delivery of therapeutics.

Alcohol use and alcohol-related consequences based on gender and sexual orientation among college students.

BACKGROUND AND OBJECTIVES: Research has not yet investigated how the association between alcohol and alcohol-related consequences differs across cisgender heterosexual women (CHW), cisgender heterosexual men (CHM), and sexual and gender minority (SGM) college students. METHODS: Participants were N = 754 college students (34.5% CHW [n = 260]; 34.5% CHM [n = 260]; 31.0% SGM [n = 234]) between the ages 18 and 25 who completed a survey on sexual orientation, gender identity, alcohol use (i.e., average drinks per week), and alcohol-related consequences. RESULTS: Among individuals who reported alcohol use, CHM reported significantly more drinks per week compared to CHW and SGM. The logistic model of a zero-inflated negative binomial regression indicated that excess zeros in the alcohol-related consequences were more likely among (1) nondrinkers and (2) SGM compared to CHM. The count portion of the model indicated that, among drinkers, there was a positive association between drinks per week and alcohol-related consequences. Estimated alcohol-related consequences per drink were 1.90% higher among CHW than CHM and 2.76% higher among SGM than CHM. Exploratory analyses did not find significant differences in outcomes between cisgender female and male sexual minority students. DISCUSSION AND CONCLUSION: Findings suggest that although CHW and SGM students consume less alcohol than CHM, these students experience more alcohol-related consequences per drink. SCIENTIFIC SIGNIFICANCE: This study advances the field's knowledge of alcohol use patterns and consequences among SGM college students. There is a need for alcohol education programming that is tailored to the unique experiences, identities, and minority stressors of SGM college students.

New developments in tuberculosis diagnosis and treatment.

Tuberculosis (TB) is a major cause of morbidity and mortality worldwide. It is estimated that 25% of the world's population are infected with Mycobacterium tuberculosis, with a 5-10% lifetime risk of progression into TB disease. Early recognition of TB disease and prompt detection of drug resistance are essential to halting its global burden. Culture, direct microscopy, biomolecular tests and whole genome sequencing are approved methods of diagnosis; however, their widespread use is often curtailed owing to costs, local resources, time constraints and operator efficiency. Methods of optimising these diagnostics, in addition to developing novel techniques, are under review. The selection of an appropriate drug regimen is dependent on the susceptibility pattern of the isolate detected. At present, there are 16 new drugs under evaluation for TB treatment in phase I or II clinical trials, with an additional 22 drugs in preclinical stages. Alongside the development of these new drugs, most of which are oral medications, new shorter regimes are under evaluation. The aim of these shorter regimens is to encourage patient adherence, and prevent relapse or the evolution of further drug resistance. Screening for TB infection, especially in vulnerable populations, provides an opportunity for intervention prior to progression towards infectious TB disease. New regimens are currently under evaluation to assess the efficacy of shorter durations of treatment in this population. In addition, there is extensive research into the use of post-exposure vaccinations in this cohort. Worldwide collaboration and sharing of expertise are essential to our ultimate aim of global eradication of TB disease. Educational aims: Differentiate between TB infection and TB disease.Understand the different methods of diagnosing TB disease and resistance.Recognise the different drugs and regimens currently in use for TB disease.Be able to discuss risk of TB disease in TB infection, and assist patients in making an informed decision on treatment for TB infection.

A Mixed Media Campaign to Promote Bystander Intervention and Reduce Alcohol Use Among College Students: A Pilot Study.

This study examined the limited efficacy of a mixed media campaign that promoted bystander intervention as a sexual violence (SV) prevention strategy and aimed to decrease alcohol use. A quasi-experimental design was used to assess the limited efficacy of the Be a Watch Dawg mixed media campaign implemented at a large Southeastern public university in 2017. Social marketing along with social cognitive theory, social norms theory, and theory of planned behavior were utilized as the framework for the campaign. Be a Watch Dawg promoted bystander intervention in SV risk situations and targeted bystanders' alcohol use via social media (e.g., Facebook, Instagram, and Twitter) and printed materials (e.g., posters, stickers, and handbills). Participants included 244 undergraduate students 18 to 24 years of age. Study outcomes included bystander intervention, intentions to intervene, and alcohol use. Adjusted linear regression and logistic regression models were used to examine differences in outcomes between pre and postcampaign samples as well as associations with campaign exposure. Significant increases in bystander intervention were observed between the pre and postcampaign samples. Campaign exposure was marginally related to intentions to intervene but was not significantly associated with bystander intervention. Social media analytics revealed that the campaign reached 39,466 social media users and received 50,854 impressions and 19,523 views. A mixed media campaign may be a promising and low-resource approach to increase bystander intervention as a strategy to combat campus SV.

Barriers to addressing alcohol use in college sexual assault prevention: Where we stand and future steps.

Purpose of Review: The aims of this paper are two-fold. First, we review the current evidence on sexual assault prevention programming that also targets alcohol. Second, we identify barriers to including alcohol use in sexual assault programs and provide recommendations to overcome these barriers. Recent Findings: We identified six sexual assault programs that also include alcohol use content, four of which have yet to be rigorously evaluated. To further refine sexual assault prevention efforts, we identified four barriers that need to be overcome including: (1) alcohol and sexual assault prevent efforts are currently siloed, (2) fear of victim blaming when integrating alcohol into programs for women, (3) a lack of evidence on how alcohol impacts bystanders, and (4) uncertainty about how to include content related to alcohol and sexual consent communicated. Summary: Researchers and preventionists with expertise in alcohol and/or sexual assault prevention need to work together with stakeholders and students on college campuses to overcome these barriers and address a key correlate of sexual assault.

ANCA associated glomerulonephritis in tuberculosis: a paradoxical reaction.

We present a case of antineutrophil cytoplasmic antibodies (ANCA)-associated rapidly progressive glomerulonephritis in the context of treatment of pulmonary tuberculosis (TB). A 42-year-old woman was treated for drug-susceptible pulmonary TB and represented with paradoxical worsening of symptoms and radiological features. She was HIV negative. A severe acute kidney injury with features of glomerulonephritis was evident on admission. Perinuclear ANCA and antimyeloperoxidase antibodies were present in serum and renal biopsy was consistent with ANCA-associated vasculitis. The patient was successfully treated with both antituberculous therapy and immunosuppression (corticosteroids and mycophenolate mofetil) with subsequent clinical improvement and amelioration of renal function. We propose this is the first case that describes the association between paradoxical reactions during TB treatment and ANCA-associated glomerulonephritis.

Division 21 has been devoted to human-centered design since the 1950s: Comment on Lyon, Brewer, and Areán (2020).

In the article, "Leveraging Human-Centered Design to Implement Modern Psychological Science," Lyon et al. (2020) presented a case for human-centered design without noting that this has been the focus of Division 21, Applied Experimental and Engineering Psychology, since its founding in 1957. Once acquainted with the work and expertise of Division 21 members, APA members will find the division is devoted to applications of psychological science in all areas of human-centered design and, with its collaborative and interdisciplinary focus, a force to reduce siloing in psychology.

Trends in Adolescent Rapid Repeat Pregnancy in Canada.

OBJECTIVE: Rapid repeat pregnancy (RRP), a birth occurring within 33 months of a previous birth, is associated with adverse neonatal outcomes. RRP occurs among 25%-35% of adolescents who become pregnant. The current study examines trends in and outcomes of adolescent RRP in the Canadian context. METHODS: Using population-based data from the Discharge Abstract Database, we linked maternal and newborn records from labour and delivery hospitalizations across Canada (excluding Québec) from fiscal years 2004/2005 to 2014/2015. Women were included if they were aged younger than 20 years at the index birth event and delivered an infant during the study period. We assessed absolute rates of RRP and differences between groups using χ2 tests. Linear tests for trend assessed change over time. Conditional logistic regression models assessed odds of adverse maternal and neonatal outcomes in RRPs compared with first pregnancies. RESULTS: Overall, we captured 67 957 adolescent pregnancies during the study period. Of these, 32.9% (95% CI 32.5%-33.2%) had an RRP. Rates of RRP were higher among 18- to 19-year-olds (34.1%; 95% CI 33.6%-34.5%) than 15- to 17-year-olds (30.4%; 95% CI 29.7%-31.0%). There was substantial variation in RRP rates across provinces and territories, from 24.5% (95% CI 23.6%-35.6%) in British Columbia to 47.3% (95% CI 46.1%-48.4%) in Manitoba. Generally, the odds of maternal or neonatal morbidity were similar in second pregnancies. However, adolescents had decreased odds of having a small-for-gestational-age infant in their second pregnancy (P < 0.001), affecting 0.4% (95% CI 0.3%-0.7%) of second pregnancies. CONCLUSIONS: Adolescents who experience a pregnancy are at high risk of experiencing an RRP; however, odds of maternal and neonatal morbidity were similar in second and first pregnancies.

Using Variable Priority Training to Examine Video Game-Related Gains in Cognition.

OBJECTIVES: Identify mechanisms associated with video-game-related gains in cognitive functioning. METHOD: Seventy-nine older adults (Mean age = 72.72, SD = 7.16) participated in a pretest-posttest intervention study. A video game that required four cognitive abilities was developed. The game had two modes: (1) variable priority training (VPT) and (2) single priority training (SPT). After a pretest session, participants completed a battery of cognitive tasks and 'were randomly assigned to either the VPT (n = 42) or the SPT mode (n = 37) for an average of 15.94 (SD = 2.15) one-hour game play sessions. Post-testing was administrated within one week after completion of training. RESULTS: Time (pretest/posttest) by game mode (VPT/SPT) interactions were examined using Multivariate Repeated Measure ANOVAs. No significant multivariate training effects were observed. DISCUSSION: Results suggest that VPT may not be the underlying mechanism responsible for video-game-related gains in cognition. Our results also cast doubts on whether playing video games could lead to cognitive enhancements in older adults.
