Summary
Individuals with high math anxiety exhibit increased gamma-band activity, a neural marker linked to threat perception and attention. This neurophysiological finding suggests a bias towards numerical stimuli in those with math anxiety.
Area of Science:
- Neuroscience
- Cognitive Psychology
- Educational Psychology
Background:
- Gamma-band activity (40-100 Hz) is associated with threat perception, attention, and anxiety.
- Math anxiety research indicates involvement of attention and threat processing, but lacks neurophysiological investigation.
- Previous studies link gamma modulation to heightened anxiety responses.
Purpose of the Study:
- To investigate the neurophysiological underpinnings of math anxiety using electroencephalography (EEG).
- To examine gamma-band activity differences in individuals with high versus low math anxiety during numerical task processing.
Main Methods:
- Two electroencephalography (EEG) studies were conducted.
- Study 1 measured gamma-band differences during complex addition and multiplication stimuli.
- Study 2 replicated Study 1, incorporating a non-numerical control condition to isolate numerical processing effects.
Main Results:
- Significantly greater gamma power was observed in high math anxiety individuals compared to low math anxiety individuals during numerical tasks.
- This heightened gamma activity in high math anxiety individuals was specific to numerical stimuli, not observed in the non-numerical control condition.
- Results indicate an attentional bias and threat perception towards numerical stimuli in high math anxiety individuals, as reflected by gamma power.
Conclusions:
- This study provides the first neurophysiological evidence of elevated gamma-band activity in individuals with high math anxiety.
- Findings suggest that gamma-band activity serves as a neural index for attentional bias and threat perception in math anxiety.
- Establishes a foundation for further research into gamma activity patterns associated with math anxiety.

When two or more atoms come together to form a molecule, their atomic orbitals combine and molecular orbitals of distinct energies result. In a solid, there are a large number of atoms, and therefore a large number of atomic orbitals that may be combined into molecular orbitals. These groups of molecular orbitals are so closely placed together to form continuous regions of energies, known as the bands.
The energy difference between these bands is known as the band gap.

1.8K
Drug design is a dynamic field that involves discovering and developing new medications based on specific biological targets. This process heavily relies on structure-activity relationships (SAR) and quantitative structure-activity relationships (QSAR) to guide the design and optimization of efficient drugs.
SAR studies the intricate relationship between a drug's chemical structure and biological activity. It focuses on understanding how modifications to a drug's structure can influence...

01:18Anxiety: Overview
1.0K
Anxiety is a common mental disorder featuring excessive worry, fear, and apprehension, significantly affecting daily life. People with anxiety disorders experience persistent and intense anxiety, interrupting their everyday functioning.
Individuals with anxiety often experience a range of physical and emotional symptoms, including sweating, trembling, tachycardia, and disturbances in sleep patterns. These symptoms vary in intensity and frequency but are generally disruptive and distressing.

6.6K
Local anesthetics (LAs) are drugs that induce a temporary loss of sensation in a limited body area, preventing pain. Cocaine was the first local anesthetic discovered in the late 19th century. Cocaine is a benzoic acid ester obtained from the leaves of coca shrubs and was often used for its psychotropic effects. Cocaine was first isolated in 1860 by Albert Niemann. Sigmund Freud studied the physiological actions of cocaine. Carl Koller later introduced it into clinical practice in 1884 as a...

In any LTI (Linear Time-Invariant) system, the convolution of two signals is denoted using a convolution operator, assuming all initial conditions are zero. The convolution integral can be divided into two parts: the zero-input or natural response and the zero-state or forced response, with t0 indicating the initial time.
To simplify the convolution integral, it is assumed that both the input signal and impulse response are zero for negative time values. The graphical convolution process...

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...
