What is the attentional network test?

What is the attentional network test?

The ANT is a task designed to test three attentional networks in children and adults: alerting, orienting, and executive control. Efficiency of the alerting network is examined by changes in reaction time resulting from a warning signal.

What is the attentional network task?

The Attention Network Test (ANT) is a task designed to test three attentional networks: (1) alerting, (2) orienting, and (3) executive control. Each network is assessed via reaction times (RTs).

What is the ANT test?

Objective: The Attention Network Test (ANT) is a tool used to assess the efficiency of the 3 attention networks-alerting, orienting, and executive control.

How do attentional networks operate?

We view attention in terms of three interrelated neural networks in the human brain. These networks carry out the specific functions of developing and maintaining the alert state, orienting to sensory input, and executive control. The ANT can also serve as an endophenotype for genetic studies on attentional networks.

What is Attention Network?

Attention network may refer to: Dorsal attention network, a network of brain regions involved in control of attention. Ventral attention network, a network of brain regions involved in detection of stimuli. Artificial neural networks used for attention (machine learning)

What is the executive attention network?

An executive attention network, also called the cingulo-opercular network, allows voluntary control of behavior in accordance with goals.

What is Ant in automation?

Apache Ant is a software tool for automating software build processes which originated from the Apache Tomcat project in early 2000 as a replacement for the Make build tool of Unix. Unlike Make, which uses the Makefile format, Ant uses XML to describe the code build process and its dependencies.

What are the four types of attentional control?

Definition of Attention While it involves our tending to facets of our environment, the nature of our attention can vary from event to event. There are four main types of attention that we use in our daily lives: selective attention, divided attention, sustained attention, and executive attention.

What part of the brain controls attention?

frontal lobe
The front of the brain behind the forehead is the frontal lobe. The frontal lobe is the part of the brain that helps people to organize, plan, pay attention, and make decisions.

What are attention layers?

At both the encoder and decoder LSTM, one Attention layer (named “Attention gate”) has been used. So, while encoding or “reading” the image, only one part of the image gets focused on at each time step. And similarly, while writing, only a certain part of the image gets generated at that time-step.

How is attention calculated?

The attention weights are calculated by normalizing the output score of a feed-forward neural network described by the function that captures the alignment between input at j and output at i.

What is executive attention example?

Imagine leaving a parking lot to drive home in the evening. If your usual routine is to drive straight home, then executive attention is needed to intervene and activate the thought of going first to, say, a grocery store . The automatic response of driving home must be inhibited or else it will control behaviour.

What kind of test is the attention network test?

The Attention Network Test (ANT; Fan et al., 2002). The ANT is an individually administered computer-based test that provides measures of the alerting, orienting, and executive attention networks within a single task. The test combines a spatial cueing task (Posner & Cohen, 1980) and a flanker task (Eriksen & Eriksen, 1974).

Are there any clinical studies of the attention network?

A range of experimental, neuroimaging, and clinical studies have supported the theory [ 2 – 4] and Berger and Posner [ 5] as well as Fan et al. [ 6] have argued that the attention network model is of special interest in studies of attentional disorders, e.g. the Attention Deficit Hyperactivity Disorder (ADHD).

Who is the creator of the attentional network task?

The Attentional Network Task as originally developed by Fan et al (2002). Download Test The revised version of the ANT as described in Fan et al (2009). Download Test The revised version of the ANT using mouse tracking as described in Yamauhi et al (2019).

Which is better for attention ant or RT?

In a randomized study, we found that even a few hours of mindfulness meditation (integrative body–mind training, IBMT®) improves executive attention as measured by the Attention Network Test (ANT) compared to relaxation training (RT), see Fig. 3.1.
