Research

There are various projects done in the lab, which collectively focus on the topics of cognitive control, cognitive training, and the use of mobile, ecological tools to assess cognitive function, mood and behavior. Studies are done in the lab but also in the field, using mobile phone apps, smart tracking bands, and wearable devices. Some of the studies use EEG to measure brain activity and track correlates of cognitive and mood states.

The link between depression, inhibitory control, and daily mood variability- Inhibitory control training for depression

 

Major depressive disorder (MDD) is a chronic condition, characterized by emotional, physical, motivational and cognitive symptoms. In terms of cognitive abilities, inhibitory control, the executive function process which allows us to maintain goal-directed behavior while ignoring distractions, is considered a key, and even causal factor, in depression. Despite its significance for depression, we still lack the knowledge about the variation in inhibitory control in daily life, and the link between inhibitory control and ecological, daily variations, in mood.

The current project will use a mobile app (‘Moodify’) to monitor and track, ecologically, participants’ mood, and measure the link between mood variations and inhibitory control. Inhibitory control is measured using various tasks, including multiple object tracking, Stroop task and a Go/No-Go task.

Inhibitory control training for depression

 

Given that inhibitory control seems key in depression, the current project aims at testing whether adaptive, mobile training of inhibitory control abilities can reduce depressive symptoms in those suffering from various mental health conditions. Training is performed using an app installed on the participant's mobile device, and varies adaptively based on individual performance. Cognition, depression, anxiety and function is measured at baseline, immediately following training and after a few weeks (follow up). The study is conducted on a sample of youth at a mental health facility in Nes Ziona.

Improving cognition and function in cancer survivors

Between 30-50% of cancer survivors report cognitive decline, which may result from the malignancy itself or is a by-product of treatments (chemotherapy, radiation). The current pilot study will test the effectiveness of a combined treatment approach, which includes remote cognitive training and functional treatment using tele-rehabilitation. We will assess cognitive function, quality of life and daily function in adult cancer survivors.

The link between mood, emotion and empathy

Our ability to empathize with others is affected by our mood and the intensity of our emotional experience. In the current study, we examine the effects of mood on our ability to emphasize.

Monitoring and building resilience of male and female warriors in IDF, using ecological, mobile tools

Resilience is an important factor determining how well warriors can cope with stressors during their military service. However, the factors affecting resilience and its manifestation in daily life is not well understood. In the current research, we will use a mobile application and a smart tracking watch to monitor resilience of male and female warriors during their training, and then measure how inhibitory control training improves resilience in these populations. We will also study the differences in resilience and coping with challenges between male and female warriors.

The DiSCoVeR Project: Examining the synergistic effects of a cognitive control videogame and a home-based, self-administered non-invasive brain stimulation on alleviating depression

In this collaborative EU project, we will apply a combined remote intervention to treat major depression: a novel cognitive control videogame and at-home non-invasive brain stimulation (NIBS). During the last 2 years of the project we will conduct a multi-site RCT in Germany, Latvia and Israel to test the feasibility and efficacy of this technology.

ADHD through the lifespan

List of studies on the subject

Ecologically tracking the link between emotion regulation and cognitive control in ADHD

Emotional dysregulation is considered key in ADHD. Yet, measuring emotion dysregulation using a one-time measurement in the lab is difficult. In addition, the link between emotion dysregulation and executive function, which is also compromised in ADHD, is still not understood. In the current study, we use ecological monitoring – using mobile apps and smart watches – to measure daily variations in emotion regulation and in executive function, and measure their co-variation over time.

The effect of non- invasive brain stimulation on pediatric ADHD

Deficits in executive functions, the cognitive processes underlying goal-directed behaviors, are considered a core mechanism in ADHD. Since current treatment options have limited effectivity, there is a pressing need for novel, efficacious interventions that target executive functions directlyWe will examine the feasibility and efficacy of a novel treatment approach, combining two treatments targeting executive functions directly: Non-Invasive Brain Stimulation (NIBS) over prefrontal cortex, and cognitive control training (CCT). ADHD symptoms, executive functions and neural signals will be measured before and after treatment.

According to the literature, the results of studies regarding EEG indices as neuronal markers for ADHD are controversial. As part of the study, we will examine whether there is a difference between the ADHD groups and a control group without ADHD in executive function indices as well as in neuronal indices - using EEG tests, where the focus is on Beta , Theta and the beta-beta ratio (TBR). We will also examine whether there is a correlation between the neuronal indices and the executive functions and whether the relationship in these indices differs between the two groups (ADHD versus the control group).
