Scientific research on verbal fluency tests: A bibliometric analysis

Normative Data Estimation in Neuropsychological Tests: A Systematic Review

“…Price’s law ( Price, 1963 ) is the most widely used indicator of the productivity and growth of a specific field or country ( Villalobos et al., 2022 ). This productivity growth can be graphically synthetized by applying linear and exponential trend lines to a chronological distribution of the literature.…”

“…Additionally, doubling time and annual growth rate were also calculated, as they are related to the growth of the field. To estimate the doubling time ( D ) of the scientific literature, the equation \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{upgreek} \usepackage{mathrsfs} \setlength{\oddsidemargin}{-69pt} \begin{document} $D=\frac{LN(2)}{LN\ (g)}$\end{document} was used ( Villalobos et al., 2022 ). The growth rate equation was \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{upgreek} \usepackage{mathrsfs} \setlength{\oddsidemargin}{-69pt} \begin{document} $C(t)={cg}^t$\end{document} ( Egghe & Ravichandra Rao, 1992 ), where C ( t ) is the total number of papers produced at time t and c and g were the estimated constants of the data.…”

“…It is calculated by dividing the number of citations in particular year by the total number of articles published in the two previous years ( Garfield, 1979 ). This indicator is frequently used for ranking, evaluating, and comparing journals ( Garfield, 1979 ; Villalobos et al., 2022 ). Although it is a controversial indicator (because it is calculated using as the numerator the total number of citations received by the journal, including news citations, editorials, and letters to the editor), it is still a benchmark index of the impact of journals ( Villalobos et al., 2022 ).…”

“…A bibliometrics approach allows one to examine research activity and evolution in a given topic using diverse quantitative indices (e.g., doubling time, form of growth, Bradford zones, impact factor, etc.) that describe both the performance analysis of the general characteristics of publications and scientific mapping ( Villalobos et al., 2022 ).…”

Symptoms of ADHD and Autism Spectrum Disorder Interactively Predict Children’s Verbal Fluency

“…Verbal fluency involves naming unique items from a designated semantic category (i.e., semantic fluency; e.g., “tell me all the animals you can think of”) or starting with a certain letter (i.e., letter fluency; e.g., “tell me all the words that start with the letter A”) within a limited timeframe (Federmeier et al, 2010; Randolph et al, 1998; Regard et al, 1982; Shao et al, 2014; Villalobos et al, 2022). Verbal fluency has been shown to predict a variety of cognitive and life outcomes, such as reading and handwriting performance in typically developing (TD) individuals, those with dyslexia (Rodríguez-Aranda, 2003; Shareef et al, 2019, and those with autism spectrum disorder (ASD; Chan et al, 2022).…”
