Summary
This study addresses acalculia, an acquired calculation disorder typically linked to left parietal lobe damage. It proposes clinical interventions for both primary (anarithmetia) and secondary acalculia types.
Area of Science:
- Neuroscience
- Cognitive Psychology
- Clinical Neurology
Background:
- Acalculia is an acquired disorder affecting calculation abilities.
- It is commonly associated with damage to the left posterior parietal lobe.
- Two main types are recognized: primary acalculia (anarithmetia) and secondary acalculia.
Purpose of the Study:
- To propose clinical interventions for rehabilitation of acquired acalculia.
- To differentiate between primary and secondary acalculia.
- To outline strategies for addressing calculation deficits.
Main Methods:
- Review of existing literature on acalculia.
- Analysis of cognitive and neurological underpinnings of calculation disorders.
- Development of a framework for clinical intervention.
Main Results:
- Primary acalculia (anarithmetia) involves a loss of numerical concepts affecting oral and written calculations.
- Secondary acalculia results from other cognitive disturbances (aphasia, alexia, agraphia, executive dysfunction, visuospatial difficulties) impacting mathematical skills.
- The proposed interventions aim to address the specific deficits of each acalculia type.
Conclusions:
- Effective rehabilitation requires understanding the distinct mechanisms of primary and secondary acalculia.
- Tailored clinical interventions can improve calculation abilities in individuals with acquired acalculia.
- Further research is needed to validate proposed rehabilitation strategies.

02:26Ecological Disturbance
20.8K
An ecological disturbance is a temporary disruption in the environment resulting from abiotic, biotic, or anthropogenic factors, causing a pronounced change in an ecosystem. The impact of an ecological disturbance, which can depend on its intensity, frequency, and spatial distribution, plays a significant role in shaping the species diversity within the ecosystem.

2.7K
Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow heart...

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

02:46Calculating the Equilibrium Constant
37.6K
The equilibrium constant for a reaction is calculated from the equilibrium concentrations (or pressures) of its reactants and products. If these concentrations are known, the calculation simply involves their substitution into the Kc expression.
For example, gaseous nitrogen dioxide forms dinitrogen tetroxide according to this equation:

02:49Calculating Standard Free Energy Changes
24.8K
The free energy change for a reaction that occurs under the standard conditions of 1 bar pressure and at 298 K is called the standard free energy change. Since free energy is a state function, its value depends only on the conditions of the initial and final states of the system. A convenient and common approach to the calculation of free energy changes for physical and chemical reactions is by use of widely available compilations of standard state thermodynamic data. One method involves the...

02:45Calculating pH Changes in a Buffer Solution
57.8K
A buffer can prevent a sudden drop or increase in the pH of a solution after the addition of a strong acid or base up to its buffering capacity; however, such addition of a strong acid or base does result in the slight pH change of the solution. The small pH change can be calculated by determining the resulting change in the concentration of buffer components, i.e., a weak acid and its conjugate base or vice versa. The concentrations obtained using these stoichiometric calculations can be used...
