Precocial avian hatchlings are typically highly social and show strong species-typical preferences for the maternal calls of their own species. The influence of social contingencies on the acquisition of species-specific preferences has, however, largely been neglected. We found that exposing bobwhite (BW) quail chicks to a Japanese quail (JQ) call contingent on their own vocalizations for 5 min was sufficient to eliminate their species-typical preference for the BW maternal call. Yoked, noncontingent exposure had no such effect. The introduction of variability to the contingency, but not a lengthening of the training session, was found to engender even higher preferences for the JQ call. Chicks provided with contingent exposure to the JQ call on a variable ratio schedule showed a significant preference for the JQ over the BW maternal call, whereas chicks provided with equivalent fixed ratio exposure did not. These results highlight the role that social interaction and contingency can play in the acquisition and maintenance of species-specific auditory preferences in precocial avian species.
Objective The purpose of this study was to investigate the prevalence of Emotional Intelligence (EI) research among 19 Latin American countries. Participants and Method Respective to each country, Total Life Science publications and Psychology publications were gathered from “UNESCO Science Report Towards 2030.” Population and GDP statistics pertaining to each country were derived from CIA Factbook. Mean education and percentage of GDP allocated for education were gathered from UNESCO Institute for Statistics. The databases SciELO and Redalyc were used to exhume the number of published Emotional Intelligence articles. The term “inteligencia emocional” was used. Findings were filtered to meet inclusion criteria: peer-reviewed, published between 2008-2018, corresponding to a Psychology related subject. Duplicate articles, those that did not contain the term “inteligencia emocional” in the abstract and articles that were not listed under the Psychology category were excluded. Results Data analysis of 19 countries from 2008-2014 revealed the mean number of Emotional Intelligence published articles to be 2.65 (SD = 5.54) articles per country - with a maximum of 22 and a minimum of 0. The percent of articles featuring EI in relation to Total Psychology articles published had a mean of 7% - with Minimum of 0% and Maximum of 60%. Bolivia has the highest percentage of articles on EI (60%), whereas Colombia the highest total number of articles published (n = 41). Population was significantly correlated with Total Articles Published and Total Psychology Articles Published. Conclusions Emotional Intelligence in Latin American countries is not widely investigated. Findings revealed 12 out of 19 Latin American countries had one or more publications related to Emotional Intelligence. While population was shown to be related to the number of articles published in Life Sciences and Psychology, it did not reveal a correlation with the publication of studies regarding EI. Furthermore, education and GDP were not related to the overall publication of articles.
Objective Traumatic brain injuries (TBIs) are not uniformly represented across monolinguals and bilinguals. Processing speed is often impacted as a result of a TBI. The objective of this study is to examine how processing speed is influenced by linguistic abilities after sustaining a TBI. Hypothesis: bilinguals will perform better than monolinguals on measures of processing speed. Method A total of 89 subjects, 36 monolinguals with a mean age of 37.83 (SD = 13.25) and 53 bilinguals with a mean age of 37.74 (SD = 13.53) were grouped based on language ability and performance was compared on the Trail Making Test, Part-A (TMT-A), Processing Speed Index (PSI) of the Wechsler Adult Intelligence Scale, 4th Edition (WAIS-IV), and the Symbol Search (SS) and Coding (CD) subtests of the PSI. Results An independent samples t-test revealed a significant different between bilinguals and monolinguals on TMT-A [t (87) = .154, p = .003], CD subtest [t (87) = −.823, p = .008], and PSI [t (87) = −2.10, p = .014]. There was not a significant difference observed on the SS subtest [t (87) = −2.71, p = .364]. Conclusion This study revealed that bilinguals demonstrated better performance on measures that emphasize scanning, cognitive flexibility, sequencing abilities, and visual–spatial functioning. These data suggest that bilinguals perform at an average level while monolinguals perform on a low average level regarding processing speed after sustaining a TBI.
Objective This review examines studies that have identified both social and “cold” cognition in moderating emotional functioning as an outcome in individuals post-traumatic brain injury (TBI). Data Selection A systematic search of the literature was conducted using the keywords: social cognition, hot cognition, cognitive processes, emotions, emotional functioning, TBI, ABI, brain injury. The search included five databases: (1) EBSCOhost, (2) Google Scholar, (3) ScienceDaily, (4) PubMed, (5) World Health Organization. Inclusion criteria consisted of peer-reviewed articles published in English between 2013–2019 that utilized measures examining aspects of “cold cognition,” measures that investigated social cognition, and, outcome measures of emotional functioning in individuals who sustained a TBI. Data Synthesis A total number of 27 studies were identified through database searching with 16 papers selected. Three studies explained the function and implication of social cognition in individuals post-TBI. Additionally, 4 articles integrated statistical and demographic analyzes on individuals who suffered a TBI, and 9 studies exposed the relationship between “hot” and “cold” cognitions after sustaining a TBI. Conclusions Our results suggest that individuals with a TBI often exhibit difficulties in social cognition that is linked to changes in emotional functioning. Several studies pointed to the limbic system as an area influenced by both social and “cold” cognition regarding emotional output and experiences. Conversely, this system is often impacted in TBI. Other studies emphasized the relationship between attention and perception regarding one’s ability to adequately engage in empathy, emotional resonance, and sensitivity. Additionally, these studies outlined how impaired executive functioning influences empathy, attention, decision-making, and Theory of Mind.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
