Game changer? Cognitive-motor effects of VR exergaming compared to video-based training.

BACKGROUND/OBJECTIVE: Virtual reality (VR) exergaming enhances several cognitive domains through multisensory engagement. Acute cognitive benefits of VR are established, but evidence for direct comparisons with non-immersive controls is limited. This study aimed to determine whether VR exercise provides additional cognitive and cognitive-motor benefits beyond a matched non-immersive active stick-fight video (SFV) intervention, and whether effects persist after training. METHODS: In this randomized quasi-experimental study, N&#x2009;=&#x2009;55 healthy adults (VR: n&#x2009;=&#x2009;30; SFV: n&#x2009;=&#x2009;25; 25.5&#x2009;&#xb1;&#x2009;7.1&#x2009;years; 41.8% female) completed an 8-week program (2&#x2009;&#xd7;&#x2009;30&#x2009;min/week), of VR or SFV matched in movement patterns, frequency, intensity and duration. Measurements included reaction time (RT), Stroop Test (versions 1-3), Letter Cancellation Test (LCT), Trail Making Test (TMT), Trail Walking Test (TWT) and Fitts task (difficulty level 1-4). Data were analyzed using mixed-design ANOVAs. RESULTS: Improvements were observed in Stroop reading (F(1,53) = 14.84, p < .001, &#x3b7;2 = 0.219), Stroop inhibition (F(1,53) = 10.99, p = .002, &#x3b7;2 = 0.172), and LCT (F(1,53) = 4.57, p = .037, &#x3b7;2 = 0.079). A time&#x2009;&#xd7;&#x2009;group interaction was found for TMT (F(1,53) = 6.55, p = .031, &#x3b7;2 = 0.110), indicating greater changes following VR training. Both groups improved cognitive-motor performance (TWT: F(1,25) = 55.32, p < .001, &#x3b7;2 = 0.689; Fitts3: F(1,53) = 44.97, p < .001, &#x3b7;2 = 0.459), with greater gains for VR in Fitts3 (p = .006). CONCLUSION(S): Eight weeks of VR and SFV enhanced cognitive and cognitive-motor performance. VR provided domain-specific advantages in executive function, but these effects were not uniformly persistent. SFV sustained more improvements in real-world-relevant cognitive-motor tasks.

Aerobic fitness reduces brain tissue loss in aging humans.

BACKGROUND: The human brain gradually loses tissue from the third decade of life onward, with concomitant declines in cognitive performance. Given the projected rapid growth in aged populations, and the staggering costs associated with geriatric care, identifying mechanisms that may reduce or reverse cerebral deterioration is rapidly emerging as an important public health goal. Previous research has demonstrated that aerobic fitness training improves cognitive function in older adults and can improve brain health in aging laboratory animals, suggesting that aerobic fitness may provide a mechanism to improve cerebral health in aging humans. We examined the relationship between aerobic fitness and in vivo brain tissue density in an older adult population, using voxel-based morphometric techniques. METHODS: We acquired high-resolution magnetic resonance imaging scans from 55 older adults. These images were segmented into gray and white matter maps, registered into stereotaxic space, and examined for systematic variation in tissue density as a function of age, aerobic fitness, and a number of other health markers. RESULTS: Consistent with previous studies of aging and brain volume, we found robust declines in tissue densities as a function of age in the frontal, parietal, and temporal cortices. More importantly, we found that losses in these areas were substantially reduced as a function of cardiovascular fitness, even when we statistically controlled for other moderator variables. CONCLUSIONS: These findings extend the scope of beneficial effects of aerobic exercise beyond cardiovascular health, and they suggest a strong solid biological basis for the benefits of exercise on the brain health of older adults.

Alprazolam 0.125 mg twice a day improves aspects of psychometric performance in healthy volunteers.

The effects of alprazolam (0.125 mg) taken twice a day on several cognitive and performance tasks (Pictures test, Digit-Symbol Substitution Test, Choice Reaction Time [CRT], Critical Flicker Fusion [CFF]) were investigated in healthy students. A double-blind, independent group design was used to compare placebo with alprazolam (32 volunteers in each group). After random assignment, all subjects received placebo for 3 days (D) followed by 14 days of treatment with either alprazolam or placebo. Subjects completed a battery of tests at D0, D3, D7, D10, and D14. D3 performance was poorer in the alprazolam group except for CFF values (ascending values and total values), and the only significant improvement was in total reaction time on the CRT test. However, a significant improvement in performance (except in recognition reaction time) was shown at D7, D10, and D14 in the alprazolam group compared with the control group results. This study shows that repeated low doses of alprazolam produce small improvements in some aspects of psychomotor and cognitive functions. Training effect, tolerance effect, anxiolytic effect, and changes in receptor function and/or number are discussed to explain the performance improvement.

How specifically do we learn? Imaging the learning of multiplication and subtraction.

The present functional magnetic resonance imaging (fMRI) study investigates modifications of brain activation patterns related to the training of two different arithmetic operations, multiplication and subtraction. Healthy young adults were trained in five sessions to answer multiplication and subtraction problems. In the following fMRI session, trained and new untrained problems closely matched for difficulty were presented in blocked order. Contrasts between untrained and trained operations showed stronger activation of inferior frontal and parietal regions, especially along the banks of the intraparietal sulcus. The reverse contrasts, trained minus untrained operations, yielded significantly higher activation in the left angular gyrus for multiplication but no significantly activated area for subtraction. This suggests that training leads to a reduction of general purpose processes, such as working memory and executive control in both operations, indicated by the decrease of activation in inferior frontal areas. For multiplication, however, the increase of activation in the left angular gyrus indicates a switching of cognitive processes. Trained subtraction therefore seems to lead to faster and more efficient strategies, while trained multiplication showed a shift from quantity-based processing (supported by the areas along the intraparietal sulci) to more automatic retrieval (supported by the left angular gyrus). The same training method caused changes in brain activation patterns that depended on the given operation. The effects of learning on the brain therefore seem not only to depend on the method of learning but also on its content.

[Psychoeducational-psychotherapeutic treatment of schizophrenic patients and their caregivers. II. Supplementary findings at a 2-year follow-up].

In this study we investigated whether, in conjunction with neuroleptics, a psychoeducational and cognitively oriented treatment for schizophrenic outpatients and their key-persons can improve the course of schizophrenic illness within a 2-year follow-up. This prospective randomized study covered a total of 191 schizophrenic patients (according to DSM-III-R) and comprised a psychoeducational training and cognitive psychotherapy for patients and counseling for their key persons in various combinations. Patients were examined before, immediately after and 2 years after the end of the intervention. Patients in the treatment groups reduced their overall psychopathology and their attention deficit. For patients receiving all three treatment conditions, there was a relevant preventive effect with regard to the rehospitalization rate appearing during the second year of the follow-up. We conclude that in the mid-term, a combination of psychoeducational and cognitively oriented therapy for patients and their keypersons can improve the course of schizophrenic illness.

Use of wearable technologies for physical activity promotion in older adults: A systematic review.

This systematic review, conducted according to PRISMA guidelines and registered in PROSPERO (CRD420251055299), examined the use of wearable technologies for promoting physical activity (PA) in adults aged 60 years and older. Searches across five databases (PubMed, Scopus, Web of Science, CINAHL, Cochrane) identified 2438 records, of which only six randomized controlled trials published between 2021 and 2025 met inclusion criteria, with sample sizes ranging from 36 to 551 participants and mean ages between 65 and 79 years. Given the small number of included studies, findings should be interpreted as preliminary. The studies ranged from the standalone use of commercial trackers (Fitbit, Polar, ActiGraph) to multicomponent interventions combining wearables with physiotherapist feedback, telephone counseling, web-based platforms, or interactive cognitive-motor training. Wearables used alone, as in the REACT trial, produced small or non-significant PA effects. In contrast, interventions integrating devices with personalized feedback, professional support, or digital platforms, such as PROMOTE and TASMANIA, were associated with more consistent improvements in PA, physical function, and cognitive outcomes. Multicomponent programs, such as PEER and ICMT, reported broader benefits, including cognition, balance, and reductions in sedentary behavior, though these findings derive from individual trials and require replication. Risk of bias, assessed with the Cochrane Risk of Bias tool version 2 (RoB 2.0), was rated as "some concerns" for five studies and low for only one, mainly due to gaps in randomization reporting, missing data, and lack of preregistration. Tentatively, and based on a very limited evidence base, wearables may have greater impact when embedded within broader behavioral systems, incorporating feedback, coaching, or interactive components, rather than when used in isolation as passive monitoring tools. Adherence and psychosocial outcomes appeared related to comfort and perceived usefulness among older adults, though larger and more robust trials are needed to confirm these patterns.

Social problem solving training: a follow-up study of cognitive and behavioral effects.

The long term effects of Spivack and Shures' social problem-solving training were assessed and compared to an attention-placebo control. Thirty-seven preschool age children were involved in this year's long intervention project and six month follow-up. All subjects received 46 sessions of intervention by specially trained assistants. Support was found for the cognitive effectiveness of social problem-solving training with aberrant children at post test in that they gained significantly in their ability to generate alternative solutions to interpersonal problems. This differential effect was not sustained at follow-up. Blind teacher ratings of behavioral adjustment and independent observers' ratings of behavior (using a naturalistic observation scale developed for this study) revealed no significant behavioral training effects at post test or at follow-up. Findings are discussed with the suggestion that behavior change in young children may not be mediated through a strictly cognitive intervention, and may more logically require an integration of behavioral and cognitive techniques.

Examining rhythm and melody processing in young children using FMRI.

While it is often reported that musical experience can have positive effects on cognitive development in young children, the neural basis of such potential effects remains relatively unexplored. Employing functional magnetic resonance imaging (fMRI) for such research presents as many challenges as possibilities, not least of which is the fact that young children can find it difficult to remain still and attentive for long periods of time. Here we describe an fMRI scanning protocol designed specifically for young children using short scanning runs, a sparse temporal sampling data acquisition technique, simple rhythmic and melodic discrimination tasks with a button-press response, and a child-oriented preparation session. Children were recruited as part of a large-scale longitudinal study examining the effects of musical training on cognitive development and the structure and function of the growing brain. Results from an initial analysis of 33 children and from the first five children to be re-scanned after musical training indicate that our scanning protocol is successful and that activation differences can be detected both between conditions and over time.

Historical review of computer-assisted cognitive retraining.

OBJECTIVES: This article details the introduction and development of the use of microcomputers as adjuncts to traditional cognitive rehabilitation of persons with acquired brain injury. SUMMARY: The initial application of video games as therapeutic recreation in the late 1970s was soon followed in the early 1980s by the use of the first personal computers and available educational software. By the mid-1980s, both the IBM PC and Macintosh platforms were established, along with simplified programming languages that allowed individuals without extensive technical expertise to develop their own software. Several rehabilitation clinicians began to produce and market specially written cognitive retraining software for one or the other platform. Their work was detailed and reviewed, as was recently released software from commercial sources. The latter discussion included the latest developments in the rehabilitation applications of personal digital assistants and related organizing, reminding, and dictation devices. A summary of research on the general and specific efficacy of computer-assisted cognitive retraining illustrated the lingering controversy and skepticism that have been associated with this field since its inception. CONCLUSIONS: Computer-assisted cognitive retraining (CACR) can be an effective adjunct to a comprehensive program of cognitive rehabilitation. Training needs to be focused, structured, monitored, and as ecologically relevant as possible for optimum effect. Transfer or training or generalizability of skills remains a key issue in the field and should be considered the key criterion in evaluating whether to initiate or continue CACR.

Cognitive therapy, analytic psychotherapy and anxiety management training for generalised anxiety disorder.

BACKGROUND: We test the hypotheses that (a) cognitive therapy is of comparable efficacy to psychodynamic psychotherapy, (b) 8-10 sessions of therapy is as effective as 16-20 sessions, and (c) brief therapist training is as effective as intensive training. METHOD: Of 178 out-patients referred to a clinical trial of psychological treatment for generalised anxiety, 110 patients met DSM-III-R criteria for generalised anxiety disorder and were randomly assigned to three different forms of psychotherapy. The main comparison was between cognitive therapy and analytic psychotherapy, delivered by experienced therapists at weekly or fortnightly intervals over six months. A third treatment, anxiety management training, was delivered at fortnightly intervals by registrars in psychiatry after a brief period of training. Eighty patients completed treatment and were assessed before treatment, after treatment, and at six-month follow-up. RESULTS: Cognitive therapy was significantly more effective than analytic psychotherapy, with about 50% of patients considerably better at follow-up. Analytic psychotherapy gave significant improvement but to a lesser degree than cognitive therapy. There was no significant effect for level of contact. Patients receiving anxiety management training showed similar improvements to cognitive therapy after treatment, with rather lower proportions showing clinically significant change. CONCLUSIONS: Cognitive therapy is likely to be more effective than psychodynamic psychotherapy with chronically anxious patients. Significant improvements in symptoms can be achieved by trainee psychiatrists after only brief instruction in behaviourally based anxiety management. However, the superiority of cognitive therapy at follow-up suggests that the greater investment of resources required for this approach is likely to pay off in terms of more sustained improvement. There is no evidence that 16-20 sessions of treatment is more effective, on average, than 8-10 sessions.

Cognitive task analyses for decision centred design and training.

This paper presents three case studies of Cognitive Task Analysis (CTA) for defining systems design and training requirements. The approach taken involves a modification of the critical decision method of Klein et al. The authors utilized the revised CDM to obtain information from expert white-water rafting guides, general aviation pilots, and emergency ambulance dispatchers. The information obtained was used to develop multi-media tools for training rafting guides and general aviation pilots, and to redesign the VDU display requirements for the ambulance dispatchers. The examples demonstrate the utility of an approach to CTA that is closely based on relevant theory, and provides guidance to practitioners wishing to apply CTA techniques.

Randomized controlled evaluation of the effects of cognitive-behavioral stress management on cortisol responses to acute stress in healthy subjects.

Psychosocial stress is a potent activator of the hypothalamus-pituitary-adrenal (HPA) axis. While neuroendocrine stress responses are essential for the maintenance of homeostasis, evidence suggests that excessive activation of the HPA axis constitutes a risk for disease and psychopathology. The purpose of the present study was to assess the effect of cognitive-behavioral stress management training on endocrine stress responses and cognitive appraisal under acute psychosocial stress among healthy young subjects. Forty-eight healthy, non-smoking male students without acute or chronic medical or psychiatric disorder on self report were randomly assigned to receive group-based cognitive-behavioral stress management training either before or after a standardized psychosocial stress test (Trier Social Stress Test, TSST). Endocrine and psychological stress responses were assessed with salivary free cortisol response and cognitive appraisal processes to the TSST. In comparison with the control group, subjects in the treatment group showed an attenuated endocrine response (F (2.55/117.41) = 3.81; P = 0.02; effect size f(2) = 0.35) to the TSST. In addition, subjects in the SIT group had lower stress appraisal and higher control expectancies (F (2/45) = 6.56; P = 0.003, effect size f(2) = 0.29) compared to controls. Short group-based cognitive-behavioral stress management training reduces the neuroendocrine stress response to an acute stressor in healthy subjects. Therefore, stress management training may prove useful in preventing detrimental effects of stress-induced neuroendocrine activation

Therapy for youths with anxiety disorders: a second randomized clinical trial.

Ninety-four children (aged 9-13 years) with anxiety disorders were randomly assigned to cognitive behavioral treatment or waiting-list control. Outcomes were evaluated using diagnostic status, child self-reports, parent and teacher reports, cognitive assessment and behavioral observation: maintenance was examined using 1-year follow-up data. Analyses of dependent measures indicated significant improvements over time, with the majority indicating greater gains for those receiving treatment. Treatment gains returned cases to within nondeviant limits (i.e., normative comparisons) and were maintained at 1-year follow-up. Client age and comorbid status did not moderate outcomes. A preliminary examination of treatment segments suggested that the enactive exposure (when it follows cognitive-educational training) was an active force in beneficial change. Discussion includes suggestions for future research.

Effectiveness of a CD-ROM multimedia tutorial in transferring cognitive knowledge essential for laparoscopic skill training.

BACKGROUND: Computer-assisted instruction (CAI) can benefit surgical education by improving efficiency, effectiveness, standardization, and access. This study compares knowledge gains for laparoscopic skill acquisition following a standardized tutorial delivered via CD-ROM versus live instructor. METHODS: A standardized tutorial was written and subsequently converted to multimedia CD-ROM format by its author (JR). During a laparoscopic development course, experienced US-trained surgeons (n = 52) participated in the tutorial delivered live by the author. The CD-ROM tutorial replaced the instructor for the following groups: (1) experienced US-trained surgeons (n = 27); (2) US-trained surgical residents (n = 59); and (3) Greek surgeons (n = 63). A 51-item knowledge test was administered before and after tutorial instruction. RESULTS: The mean increase in scores between pretest and posttest was significant (P <0.01) and of similar magnitude in each group, with nonsignificant posttest mean differences among US-trained groups. CONCLUSIONS: The CD-ROM tutorial effectively transfers cognitive information necessary for skill development. Distance learning modes of this tutorial program may be feasible.

Psychoneuroimmunology update.

Psychoneuroimmunology is the scientific field that investigates linkages between the brain, behavior, and the immune system and the implications of these linkages for physical health and disease. Recent evidence suggests that both naturalistic and laboratory stressors can alter enumerative and functional aspects of the human immune system. Chronic stress may increase vulnerability to infectious disease; however, the role of stress in the course of inflammatory bowel disease remains unclear. Because there are large individual differences in psychological response to stress, it is important to consider the role of cognitive and affective responses to stress. Depression has been associated with functional immune decrements and immune overactivation. Cognitive states such as perceived control, views of the self, and views of the future have been associated with immune parameters and health in some studies. Very few controlled clinical trials have been conducted to determine if psychosocial interventions can impact the immune system and the progression of medical conditions. There is suggestive evidence for the health benefits of relaxation training, cognitive-behavioral stress management, and support groups; but, there is little research on many other psychosocial interventions in widespread use for medical conditions. An evidence-based discussion of this research literature with interested patients may help them make informed decisions regarding adjunctive treatments.

A comparison of EMG feedback and alternative anxiety treatment programs.

Four cohorts of 40 subjects each were randomly assigned to 1 of 10 treatment conditions utilizing EMG feedback, cognitive monitoring training, systematic desensitization, high expectancy discussion group, or waiting list controls either in isolation or in various combinations. A three-way ANOVA for repeated measures indicated that significant anxiety reductions were experienced in all noncontrol treatment conditions. Treatment groups employing EMG feedback demonstrated significantly greater anxiety decrements on Cattell's IPAT Self-Analysis Form, and baseline frontalis EMG. Adding desensitization or cognitive monitoring to EMG feedback did not produce a more powerful effect than using EMG feedback alone. Sex and age differences were also observed. Some implications are discussed.
