Contemporary research on emotions (“dispositions to action,” Lang, 1995), primarily
focuses on emotion regulation (McRae and Gross, 2020), emotional intelligence (Gong
and Jiao, 2019), and the relationship between emotion and social cognition (Stevens
and Jovanovic, 2019). Technological advances have allowed researchers to identify
the neurobiological processes underlying the emotions, in particular, functional magnetic
resonance imaging (fMRI, Weber-Goericke and Muehlhan, 2019), electrophysiological
techniques (Gantiva et al., 2019), and virtual reality (Wechsler et al., 2019). Notwithstanding
these major progresses, there is awareness of the need to continue developing methodologies
that further integrate behavioral measures and increase ecological validity. For example,
using dynamic stimuli (e.g., videos) and not just photographs, as well as combining
recording techniques that allow to understand neuronal activity underlying emotion
over the course of time (e.g., EEG in conjunction with fMRI, Pavlova, 2017).
The study of emotions is currently one of the more developed fields in behavioral
sciences, which is showing a high potential for integration across disciplines and
research areas, for example trough computational models and creation of virtual reality
environments (de Gelder, 2017). Basic and applied efforts to understand the interplay
of emotion and learning are two of those fruitful areas of interaction (Hascher, 2010;
Tyng et al., 2017; Wortha et al., 2019). Mounting evidence indicates that emotion
modulates encoding and helps retrieval of information efficiently. Also, now there
is evidence that emotion strongly affects attentional and executive processes (e.g.,
modulating selectivity of attention and motivating to action), which in turn are intimately
linked to learning processes (Tyng et al., 2017).
Aligned with this global trend in research on emotion and learning, an important number
of Latin American scientists have developed fruitful research agendas over the last
decades. Their efforts have focused on basic and/or translational research with humans
and other animal models, and on implementing diverse methodologies (Ardila et al.,
2005; Annicchiarico et al., 2013; Robayo-Castro et al., 2016; Forero et al., 2020).
Notwithstanding these important contributions, and efforts to develop regional and
international networking systems (e.g., Red Latinoamericana de Ciencias del Comportamiento—https://redlacc.org;
Sociedade Brasileira de Neurociências e Comportamento—http://www.sbnec.org.br/site/
and Asociación Latinoamericana de Neurociencias Aplicadas—http://www.neurolatam.org/index.php/en/),
Latin American research on emotion and learning has followed the overall trend of
other research fields throughout the region; namely, remaining partially hidden from
the large scientific community of the world.
Although Latin America has increased its share of world scientific publications by
nearly 2-fold during the last two decades, moving from ~2 to 4%, its output remains
below the expected level based on its proportion of world population and Gross Domestic
Product (GDP)—i.e., 5 to 6% (Van Noorden, 2014; Ciocca and Delgado, 2017). Moreover,
recent analyses show that this growth has not been equally distributed across the
region. While Brazil, Mexico, Argentina, Chile, and Colombia combined contribute to
more than 90% of all scientific publications in the region, other neighboring countries
remain behind the rest of the world (Huete-Perez, 2013). Ultimately, the scholarly
impact of scientific research produced in the region remains below world average (e.g.,
citation rate remains below 1.0; Van Noorden, 2014). Two major interrelated factors
that have contributed to this situation are that (a) most research groups tend to
work in isolation or in local sporadic collaboration, and (b) results are often published
in journals that are not indexed in key citation databases (e.g., SCOPUS or Web of
Science; Van Noorden, 2014; Ciocca and Delgado, 2017).
In view of this situation, the present special issue entitled Research on Emotion
and Learning: Contributions from Latin America aimed to engage researchers from the
region to share empirical and conceptual work on emotion and learning in the journals
Frontiers in Psychology and Frontiers in Education; two outlets that have high impact
across different disciplines (emotion science, neuroscience, educational psychology,
comparative psychology, health psychology, clinical psychology, and cognition). This
effort was expected to result in strengthening and integrating our regional community
of experts, enhancing global networking, and establishing new challenges and developments
for future investigation.
The response to this initiative in the academic community was quite positive. Forty-six
articles were submitted between November of 2017 and 2018, of which 33 were finally
published. Most of these manuscripts were classified as original research (22); the
remaining were distributed across brief research reports (5), conceptual analyses
(2), reviews (2), book reviews (1) and technology reports (1).
An analysis of the published manuscripts keywords (Figure 1) indicates relationships
to a wide range of topics. We observed differentiated emotion- and learning-related
areas, covering basic and applied research with human and non-human species (e.g.,
rats, gerbils, birds, dogs) and expanding across various methodologies (e.g., psychophysiology,
animal models, computer modeling). Worth noting is the fact that emotion-related topics
were predominant, ranging from socially relevant areas, such as conflict and emotion
regulation, to clinically and health-related areas, such as stress and psychopharmacology.

Figure 2 shows the affiliation's country of published manuscripts and collaboration
networks. Brazil, Argentina, Chile, Mexico, and Colombia were the only countries with
contributions from Latin America. Unfortunately, this replicates the unequal pattern
of scientific publications output previously identified in the region (Huete-Perez,
2013). In terms of collaboration, it practically only occurred between researchers
with Latin American affiliations and institutions in other regions (e.g., United States,
Canada, Spain, and Portugal). Collaboration between Latin American institutions was
only observed in one instance (Colombia-Mexico). Both of these findings are aligned
with previously reported patterns of collaboration (i.e., typically with non-Latin
American institutions), which have been explained by the need of better visibility,
research quality, impact factors, or international recognition (García et al., 2017).

Regarding financial support, 85.29% of the published studies in this special issue
reported funding by different sources, of which 65.51% corresponded to Latin-American
Governmental agencies. In terms of authorship indicators, a total of 140 authors participated
in the Research Topic. Only four papers were authored by a single person, and the
rest (29) included two or more authors, with a mean of 4 authors per article (an additional
indicator of collaboration).
Concerning the number of citations, as of January 2020 the average per manuscript
published in the special issue was 0.7, which impressively approached citation's average
worldwide (1.0) in a short period of time (Van Noorden, 2014). The top-three cited
papers in the Research Topic came from authors of Brazil, Chile, Spain, Belgium, and
the Netherlands. The first two were related to positive psychology and well-being,
while the third one was related to defensive emotional reactions to violent video
games.
Finally, an additional indicator of visibility is the total number of views that the
articles included in the special issue have reached. In that regard, for instance,
as of January 2020, Torres-Berrio et al.'s was positioned at the first quartile of
visibility with up to 6,600 views in <2 years since the publication of that study.
Ten other papers were positioned in quartile two, 13 papers in quartile three, and
10 papers in quartile 4 (Frontiers Loop®-https://loop.frontiersin.org/).
Conclusions
When proposed, the aim of the present Research Topic was “to increase the visibility
of Latin-American research on emotion and learning,” something that has been achieved
in a relatively brief period of time. Researchers from Latin-American countries like
Brazil, Chile, Colombia, Argentina, and Mexico, mainly (but not uniquely) interested
in emotions and learning, shared on a large scale contemporary and relevant research
across a wide range of basic, applied, and translational fields. They also showed
a very representative net of collaborations between countries known for a strong tradition
of research in North America, Europe, and Asia.
Another important aspect evidenced in the present special issue relates to the limited
investment in science in Latin America. Funding information on the published manuscripts
indicates that near half of the reported studies were supported with governmental
resources. This somewhat resembles the low percentage of spending in Research and
Development (R&D) in Latin-American countries (with the exception of Brazil, most
countries in the region allocate on average <0.7% of the GDP—UNESCO Institute for
Statistics—http://bit.ly/1USVQIP), as compared to that of developed countries in North
America and Europe (beyond 2%—UNESCO Institute for Statistics—http://bit.ly/1USVQIP).
This is a key point of interest for Latin-American researchers and their governmental
agencies; namely, despite the low access to resources, researchers in the region are
still capable of producing high-quality science. This is something that experts working
on public policies need to “keep on the table” in order to continue advocating for
increments in the resources that are greatly needed to support science in our countries.
Lastly, an aspect to highlight is the impact and visibility that most of the published
articles are showing shortly after being released. This is aligned with previously
reported growth in Latin-American science, as well as the recognition of its quality
and applicability in other regions (Huete-Perez, 2013; Van Noorden, 2014; Ciocca and
Delgado, 2017). Less than 1 year after the completion of the Research Topic, average
citation per article is very close to reach worldwide standards (1.0 citation per
article; Van Noorden, 2014).
