An Investigation of Attentional and Inhibitory Processes During Active Visual Search in Humans

The goal of this study is to investigate the finding that there are large individual differences in how participants move their eyes during active visual search. For example, some individuals tend to fixate, that is point their eyes steadily at a single location, for longer than other individuals before moving to another location. This experiment will use behavioral tasks to measure an individual's attentional and inhibitory functioning, and then see how each of these contributes to between-participant variability in eye movement behavior during visual search.

Exploratory Randomized, Controlled, Dose-response Study on the Impact of Nicotine From Five Variants of a Nicotine Tablet (NICOTINE TABLET) on Attention

This study aims to provide initial insights into the impact of orally delivered nicotine on attentional performance in adult occasional users of nicotine pouches. Nicotine will be administered via a dissolvable tablet for approximately 10 minutes. The main objective of this exploratory study is to characterize the effect of nicotine on attentional performance, using metrics derived from Continuous Performance Test (CPT). Additionally, a second CPT assessment will be conducted two hours after the first administration to explore the potential sustained effects of nicotine on attention as an exploratory objective.

Neuropsychological Patterns of Suicide Ideators and Suicide Attempters

The present study consists of 3 projects in total and aims to investigate the (neuro-) psychological patterns from suicidal ideation to suicidal behavior as well as the effects and feasibility of ASSIP Home Treatment. The overall aim of project 1 is to determine (neuro-) psychological differences between suicide attempters, suicide ideators, a clinical control group, and healthy controls. Study participants in project 1 will participate in a one-time (neuro-) psychological assessment. Project 1 of this study is an observational cross-sectional study with four groups that will be conducted at the University Hospital of Psychiatry and Psychotherapy Bern (Switzerland): Patients with at least one suicide attempt in their past (SUAT), patients with suicidal ideation (SUID), patients from the same clinical cohort, without neither suicidal behavior or ideation (CLIN) and the healthy group (HLTH). The cohorts to be examined (SUAT \& SUID) will be compared to the two control groups (CLIN \& HLTH). Only people who have signed the informed consent and meet the eligibility criteria can participate in this study.

Cereboost (American Ginseng Extract) and Brain Function

The study will assess the immediate, short-term benefits of a single dose of a supplement containing 200mg of Panax quinquefolius (American Ginseng) on cognition (brain function) in healthy young adults. To understand the effect this product may have, the participants will complete a series of questionnaires and cognitive tests (tests of memory and brain function) at set intervals across a 6-hour period. Blood samples will also be collected to assess the impact of the study product on the participants.

Impact of Attentional Tunelling on a Population of French Practitioners

The tunnel effect, also known as attentional tunnelling, is a cognitive bias affecting all healthcare professionals, including odontologists. It is characterised by an excessive focus on a specific element of a clinical situation, which can alter the overall assessment and lead to errors in medical practice. This poses a particular risk to the quality of dental care, especially surgical care. Despite the importance of this risk, few studies have addressed this issue in dentistry. Therefore, raising the dental community's awareness of this phenomenon on a large scale is both justified and necessary.

The Effects of Breathing Exercises on Exam Anxiety, Attention Deficit, and Academic Achievement in Students Preparing for University Entrance Exams

This study investigates the effects of breathing exercises on exam anxiety, attention, and academic achievement in students preparing for university entrance exams. University entrance exams are significant milestones in students' educational and career paths, often causing high levels of stress and anxiety. These psychological pressures can negatively impact learning, focus, and overall academic performance. The study will involve students who volunteer to participate and meet the inclusion criteria. Participants will be guided through structured breathing exercises designed to reduce stress and enhance concentration. The program will be conducted over several sessions, during which students will practice specific breathing techniques under supervision. Primary outcomes of the study include the assessment of changes in exam anxiety levels, attention, and academic performance. Secondary outcomes may include students' self-reported stress management skills and overall well-being. Data will be collected using validated questionnaires, attention tests, and academic performance records. The purpose of this research is to determine whether regular practice of targeted breathing exercises can provide practical benefits for students, helping them manage anxiety, improve focus, and achieve better academic outcomes. Findings from this study may also offer guidance for educators, parents, and healthcare providers on effective, low-cost interventions to support students during high-pressure academic periods. Participants are encouraged to follow instructions carefully and attend all sessions to gain the full benefit of the intervention. Participation is voluntary, and students can withdraw at any time without any negative consequences. Confidentiality of all collected data will be strictly maintained. By contributing to this research, participants will help advance understanding of non-pharmacological methods to improve student mental health and academic performance, potentially shaping future educational and stress-management programs.

Effects of VR-based Respiratory Training on Motor Reaction Time and Correctness, Stress Levels, Attention, Motor Skills, Postural Stability and Sleep Quality in Shift Healthcare Workers

This study investigates the effects of virtual reality (VR)-based respiratory training on various physiological and cognitive functions in shift-working healthcare professionals, including paramedics and nurses. The research will evaluate how VR-guided breathing exercises influence: stress levels, motor reaction time and accuracy, attention and cognitive performance, motor skills and postural stability, sleep quality Participants will be divided into three groups: VR-based respiratory training group - performing guided breathing exercises in a VR environment. Music-based relaxation group - listening to relaxing music without structured breathing instructions. Control group - no intervention. The findings will help determine whether VR-based respiratory training is an effective method for improving stress resilience, cognitive function, and physical performance in shift-working healthcare professionals.

Restorative Environments for Gait Therapy with VR

The aim of our study is to investigate the effects of landscapes during gait therapy. The investigators will evaluate the impacts of restorative landscapes as they occur in urban, rural and forest environments. Older people will experience those landscapes using virtual reality (VR) goggles during their gait training. The investigators expect the landscapes to have an effect on the following three aspects: (1) stress reduction, (2) restoration of attention and (3) change in gait parameters. For this purpose, volunteers who are currently inpatient in one of our study centers and already participating in gait therapy will be assigned to a group. The control group will receive the standard therapy. The participants of the intervention groups will receive five additional VR training sessions to the standard therapy. In these sessions, the participants will walk through urban, rural and forest landscapes and perform balance improvement exercises. The five training sessions will take place within ten days. Allocation to the control or intervention groups and their landscapes is random. At the start and end of participation, tests defining stress levels and gait parameters are carried out so that comparisons can be made between before and after treatment. The goal of the study is to find out which type of landscape supports restoration and can therefore contribute to greater gait stability. The investigators expect that improved gait stability will be promoted by stress reduction and increased attention induced by the virtual environments. The investigators are investigating the consequences of repeated application of virtual landscapes and the relationship between the effect of the landscape and the preferences and habits of the study participants.

Probing the Role of Feature Dimension Maps in Visual Cognition: Manipulations of Relevant Locations on Salience Processing? (Expt 3.1 Pilot)

How do we know what's important to look at in the environment? Sometimes, we need to look at objects because they are 'salient' (for example, bright flashing lights of a police car, or the stripes of a venomous animal), while other times, we need to ignore irrelevant salient locations and focus only on locations we know to be 'relevant'. These behaviors are often explained by the use of 'priority maps' which index the relative importance of different locations in the visual environment based on both their salience and relevance. In this research, we aim to understand how these factors interact when determining what's important to look at. Specifically, we are evaluating the extent to which the visual system considers locations that are known to be irrelevant when considering the salience of objects. We're testing the hypothesis that the visual system always computes maps of salient locations within 'feature maps', but that activity from these maps is not read out to guide behavior for task-irrelevant locations. We'll have people look at displays containing colored shapes and/or moving dots and report aspects of the visual stimulus (e.g., orientation of a line within a particular stimulus). We'll measure response times across conditions in which we manipulate the presence/absence of salient distracting stimuli and provide various kinds of cues about the potential relevance of different locations on the screen. The rationale is that by measuring changes in visual search behavior (and thus inferring computations performed on brain representations), we will determine how these aspects of simplified visual environments impact the brain's representation of important object locations. This will support future studies using brain imaging techniques aimed at identifying the neural mechanisms supporting the extraction of salient and relevant locations from visual scenes, which can inform future diagnosis/treatment of disorders which can impact our ability to perform visual search (e.g., schizophrenia, Alzheimer's disease).

The Role of Attention in Modulating the Placebo Effect

This project aims to examine whether these forms of attention to sensory information can modulate the mind-body interaction. This will be demonstrated through a study focused on the placebo effect with attention manipulation. Specifically, the project will focus on the construct of mindful attention to increase the precision of the likelihood and reduce the effects of priors, and on directed attention to modify the position and precision of the likelihood, hypothetically modulating the placebo effect. The study involves recruiting 128 healthy individuals, who will be asked to cycle on an ergometer for approximately 60 minutes, with alternating phases in which attention will be manipulated. After an initial warm-up phase, they will receive a placebo drink, presented as "highly stimulating." An additional group of 32 participants will not receive either the placebo drink or the attentional stimuli, but will undergo the same training cycles. All participants will receive a pre-intervention assessment, and heart rate, emotions, and perceived fatigue will be monitored.

Intensive Music Therapy on Cognitive Function in Subacute Stroke Rehabilitation in Malaysia

The purpose of this study is to explore whether intensive music therapy can help improve cognitive functions like memory, attention, and decision-making skills in stroke patients who are undergoing rehabilitation. This is a feasibility study, meaning it's also designed to see how practical it is to include music therapy as part of stroke rehabilitation. The investigators want to learn how well patients can participate in and stick with this type of therapy, and whether it fits well with other treatments that stroke patients usually receive. By understanding this, the investigators can assess the resources, staff training, and planning needed for music therapy to be part of stroke recovery in the future. The study will also help the investigators estimate the effects of music therapy, which will be used to design a larger, more detailed study in the future.
