Ethnicity and intelligence in children exposed to poverty environments: An analysis using the Oaxaca-Blinder decomposition

Neurodevelopmental assessments used to measure preschoolers' cognitive development in Latin America: a systematic review

OBJECTIVE

The objective of this study was to systematically review the standardized neurodevelopmental assessments used to study preschool-aged children's cognitive development in Spanish-speaking Latin America.

METHODS

The authors systematically searched PubMed, PsycINFO, and ERIC databases for peer-reviewed articles from Spanish-speaking Latin American countries. Articles were included if they measured cognitive development among children aged 2-6 years using at least one standardized assessment tool; 97 articles were included and reviewed in accordance with PRISMA guidelines to assess their use of these tools.

RESULTS

Ninety-seven studies across 13 countries used a total of 41 assessments to measure cognitive development; most widely used were the Wechsler intelligence scales (n = 46/97), particularly the Wechsler Preschool and Primary Scale of Intelligence and Wechsler Intelligence Scale for Children (n = 23 and 29, respectively). Other common assessments included the McCarthy Scales of Children's Abilities (n = 9), Raven's Progressive Matrices (n = 9), Child Neuropsychological Assessment (n = 8), and Peabody Picture Vocabulary Test (n = 7). In regions where normative data for a given assessment were unpublished, authors commonly used norms from the United States, Mexico, or Spain or did not report standard scores in their analyses.

CONCLUSIONS

The wide range of tools used in these studies presents a challenge for generalizing results when measuring the neurodevelopment of Latin American preschool-aged children. The low availability of normative data for specific regions reveals concerns if some tools are culturally and linguistically appropriate even when Spanish is a common language, particularly in low-resource settings. Future work to forge greater consistency in the use of validated measures, clarity in reporting research methods, and publication of regional normative data would benefit the field.

Psicología y Pueblos Indígenas

La pregunta sobre la existencia de características comunes inherentes a la psicología de los pueblos Indígenas de todo el mundo ha sido objeto de mucho debate. Nosotros argumentamos que los pueblos Indígenas comparten la experiencia de la colonización, así como sus consecuencias sociales y psicológicas. Desarrollamos este argumento en cuatro secciones: ( a) La historia global de la colonización y las desigualdades sociales; ( b) aspectos relativos a la identidad y los procesos grupales, incluidas la transmisión intergeneracional de valores compartidos, la conexión con la naturaleza y la promoción del cambio social; ( c) el prejuicio y la discriminación hacia los pueblos Indígenas y el rol que juegan los procesos psicológicos para promover relaciones positivas entre los pueblos Indígenas y no-Indígenas; y ( d) el impacto del trauma histórico y del colonialismo en la cognición, la salud mental y el bienestar de los pueblos Indígenas, así como la base para el desarrollo de intervenciones exitosas que integran los conocimientos Indígenas. Por último, abordamos los desafíos futuros de la investigación sobre estos temas.

Psychology and Indigenous People

Whether there are common features inherent to the psychology of Indigenous peoples around the globe has been the subject of much debate. We argue that Indigenous peoples share the experience of colonization and its social and psychological consequences. We develop this argument across four sections: (a) the global history of colonization and social inequalities; (b) aspects concerning identity and group processes, including the intergenerational transmission of shared values, the connection with nature, and the promotion of social change; (c) prejudice and discrimination toward Indigenous peoples and the role of psychological processes to improve relations between Indigenous and non-Indigenous peoples; and (d) the impact of historical trauma and colonialism on dimensions including cognition, mental health, and the well-being of Indigenous peoples as well as the basis for successful interventions that integrate Indigenous knowledge. Finally, we address future challenges for research on these topics. Expected final online publication date for the Annual Review of Psychology, Volume 73 is January 2022.
