Resumen
Los monos rhesus demuestran una comprensión del orden numérico, representando numerosidades del 1 al 9 en una escala ordinal. Este estudio revela su capacidad para la cognición numérica y la detección de disparidad ordinal.
Área de la Ciencia:
- Ciencias Cognitivas Ciencias Cognitivas.
- Comportamiento animal Comportamiento animal.
- La neurociencia es la neurociencia.
Sus antecedentes:
- Una pregunta clave en la ciencia cognitiva es si los animales pueden representar y usar computacionalmente información numérica.
- La multiplicidad se refiere a la cantidad de elementos dentro de un estímulo.
Objetivo del estudio:
- Para investigar si los monos rhesus pueden representar y ordenar estímulos visuales basados en la numerosidad.
- Para determinar si los monos rhesus pueden detectar disparidad ordinal en secuencias numéricas.
Principales métodos:
- Dos monos rhesus fueron entrenados para reconocer las numerosidades 1-4 en orden ascendente.
- Los ejemplares de estímulo variaron en tamaño, forma y color para controlar las señales no numéricas.
- Los monos fueron probados en nuevas cantidades de 5 a 9 sin recompensa para evaluar su capacidad de ordenar.
Principales resultados:
- Ambos monos ordenaron con éxito numerosidades novedosas (5-9) en una secuencia ascendente.
- Los monos demostraron la capacidad de generalizar su comprensión del orden numérico a cantidades no entrenadas.
- El rendimiento indicó el control de las características no numéricas de los estímulos.
Conclusiones:
- Los monos rhesus representan numerosidades en una escala ordinal del 1 al 9.
- Estos hallazgos apoyan la presencia de representación numérica y cognición ordinal en primates no humanos.
- El estudio proporciona evidencia de un sofisticado procesamiento numérico en monos rhesus.

How Data are Classified: Numerical Data
Data that are countable or measurable in specific units are called numerical or quantitative data. Quantitative data are always numbers. Quantitative data are the result of counting or measuring the attributes of a population. Amount of money, pulse rate, weight, number of people living in a town, and number of students who opt for statistics are examples of quantitative data.
Quantitative data may be either discrete or continuous. All quantitative data that take on only specific numerical...

Ordinal Level of Measurement
The way a set of data is measured is called its level of measurement. Correct statistical procedures depend on a researcher being familiar with levels of measurement. For analysis, data are classified into four levels of measurement—nominal, ordinal, interval, and ratio.
Data measured using an ordinal scale are similar to nominal scale data, but there is one major difference. The ordinal scale data can be ordered. An example of ordinal scale data is a list of the top five national parks in the...

Orders of Magnitude
The order of magnitude of a number is the power of 10 that most closely approximates it. Thus, the order of magnitude estimates the scale (or size) of its value. To find the order of magnitude of a number, take the base-10 logarithm of the number and round it to the nearest integer. Then the order of magnitude of the number is simply the resulting power of 10.
The order of magnitude is simply a way of rounding numbers consistently to the nearest power of 10. This makes doing rough mental math...

Percentile
A percentile indicates the relative standing of a data value when data are sorted into numerical order from smallest to largest. It represents the percentages of data values that are less than or equal to the pth percentile. For example, 15% of data values are less than or equal to the 15th percentile. Low percentiles always correspond to lower data values. High percentiles always correspond to higher data values.Percentiles divide ordered data into hundredths. To score in the...
Real Number Operations
The concept of real numbers includes all the values that can be represented on a continuous number line. The system began with basic counting values used for enumeration. It later expanded to include values that represent the absence of quantity and opposites of the counting values. When situations required expressing parts of a whole or dividing quantities evenly, values capable of representing such proportions were developed. When written using decimal notation, these values can end or repeat...
Arithmetic Sequences
An arithmetic sequence is a structured arrangement of numbers where each term is derived by adding a constant value, known as the common difference, to the previous term. This consistent pattern allows for the efficient computation of any term within the sequence as well as the cumulative sum of multiple terms. The formula for finding the nth term of an arithmetic sequence is:Here, aₙ represents the nth term of the sequence, a is the first term, d is the common difference, and n is the term...
