Automatic processing of number identity and place-value in multi-digit numbers
García-Orza, Javier
; Álvarez-Montesinos, Juan Antonio; Estudillo, Alejandro; Calleja-Reina, Marina; Rodríguez-Santos, José Miguel (2016-09-27)
The Arabic numerical system employs two dimensions to create multi-digit numbers: digits symbols and place-value. The present research explores in two numerical Stroop experiments to which extent number identity and number ... -
Do we compute the exact number of digits in the string when comparing different-length numbers?
Recent studies have shown that, when comparing multidigit numbers that differ in length (e.g., 2384-107), a decision is made considering length but also other attributes like the value of the initial digits (i.e., left-most ... -
High-frequency transcranial random noise stimulation enhances unfamiliar face matching of high resolution and pixelated faces
Estudillo, Alejandro; Lee, Ye Ji; Álvarez-Montesinos, Juan Antonio; García-Orza, Javier (Elsevier, 2023-02)
Face identification is useful for social interactions and its impairment can lead to severe social and mental problems. This ability is also remarkably important in applied settings, including eyewitness identification and ... -
How many digits are there in a multi-digit number?
García-Orza, Javier; Álvarez-Montesinos, Juan Antonio; Montenegro, Ismael R.; Cuadra Jaime, Marina (2017-09-15)
The processing of multi-digit numbers have been usually studied comparing numbers with the same number of digits. In these cases, deciding which number is bigger simply requires comparing the leftmost digit of each number. ... -
Individual differences in arithmetic fluency
García-Orza, Javier; Rodríguez-Santos, José Miguel; Calleja-Reina, Marina; Iza-Miqueleiz, Mauricio; Álvarez-Montesinos, Juan Antonio (2016-05-10)
Este estudio contrasta la hipótesis de que las dificultades que tienen algunos sujetos en el dominio de las tablas de multiplicar se deban a su incapacidad para afrontar la interferencia. Los resultados no muestran diferencias ... -
Length is not all that matters: testing the role of number identity and the ratio of fillers in comparisons of multi-digits with different digit length
García-Orza, Javier; Gutiérrez-Cordero, Ismael; Larios, Carlos; Csilinkó, Anikó; Álvarez-Montesinos, Juan Antonio (Springer, 2022-02-18)
Research in multi-digit number comparison usually considers stimuli with the same number of digits (e.g., 3452 vs. 7831). Surprisingly, there is almost no research on the comparison of numbers that differ in length (e.g., ... -
Struggling with single-digit multiplications: testing several hypotheses
Álvarez-Montesinos, Juan Antonio; Rodríguez-Montenegro, Ismael; Cuadra Jaime, Marina; García-Orza, Javier (2018-06-05)
Between 5-10% of children suffer big difficulties in learning single-digit multiplications (Geary, 2011). In accordance with previous studies, difficulties in learning multiplications would be related with interference-control ... -
The moderating role of mathematical skill level when using curricular methods to learn multiplication tables
García-Orza, Javier; Álvarez-Montesinos, Juan Antonio; Luque-Liñán, María Luisa; Matas, Antonio (Colegío oficial de la Psicología de Madrid, 2021)
The present study explores the effect of two instructional methods for children with different levels of mathematical skills. One of these methods uses a conventional approach to learning multiplication and emphasizes the ... -
Writing 1-to-3 digit numerals to dictation in Spanish: predictors and error analysis.
García-Orza, Javier; Gutiérrez-Cordero, Ismael; Gutiérrez-Fernández, Cristina; Álvarez-Montesinos, Juan Antonio; Cuadra Jaime, Marina (2023)
Mastering number transcoding demands from children the acquisition of the complexities of the Arabic place-value system and the specific rules of multi-digit numbers of their language. The present research explores the ...
