The development of emotional intelligence in childhood: associations with general developmental abilities

Emotional intelligence in young children does not develop in a vacuum, according to a comprehensive new cross-sectional study published in Frontiers in Psychology. Researchers from the University of Málaga and the University of Granada have uncovered critical links between performance-based emotional intelligence (EI) and broader cognitive and communicative milestones in children aged four to six. The findings suggest that a child’s ability to perceive, understand, and manage emotions is deeply intertwined with their general cognitive and language development, challenging historical models that treated emotional and intellectual growth as entirely separate domains.

For decades, developmental psychology has compartmentalized human growth, separating cognition, motor skills, language, and emotional competence into discrete buckets. While this siloed approach allowed researchers to dissect specific milestones with surgical precision, it obscured the synergistic ways children actually learn and grow. Recognizing this gap, a research team led by Rosario Cabello and Pablo Fernández-Berrocal set out to investigate how emotional abilities interact with general developmental domains during early childhood education, a formative window that has seen surprisingly little empirical research using objective tools.

Assessing Young Minds: Methodology and Sample Characteristics

To overcome the historical lack of objective measurement tools for early childhood emotional intelligence, the researchers deployed a specialized evaluation framework. The study examined a community sample of 377 Spanish children, consisting of 172 boys (45.6%) and 205 girls (54.4%), ranging in age from 48 to 83 months (averaging roughly six years old). The participants were recruited from six public nursery and primary schools across Málaga under strict ethical guidelines approved by the Research Ethics Committee of the University of Granada.

Each child underwent individual evaluations in quiet, distraction-free school settings using two primary standardized instruments. General developmental status was measured using the Battelle Developmental Inventory (BDI), focusing specifically on cognitive, communication, and motor domains. Meanwhile, emotional intelligence was evaluated using the Emotional Intelligence Test of the Botín Foundation for Children (TIEFBI). Grounded in the classic ability model of emotional intelligence, the TIEFBI uses a visual, hands-on format—incorporating photographs, stories, and vignettes—to bypass the linguistic limitations of young children. It evaluates three distinct sub-abilities: Catch the Emotion (perception), In Search of the Lost Emotion (understanding), and The Emotional Detective (management).

Key Findings: Gender Nuances and Age Trajectories

The analysis revealed several distinct patterns concerning age, gender, and developmental overlap. When examining gender differences through independent-samples t-tests, boys scored significantly higher on cognitive abilities (mean score of 107.27 versus 104.97 for girls, yielding a small effect size of $d = 0.27$). Conversely, girls outscored boys in emotion perception, averaging 104.35 compared to the boys’ 101.34 ($d = -0.24$). No statistically significant gender gaps emerged in communication, motor skills, emotion understanding, or emotion management.

These findings indicate that the well-documented emotional advantages often observed among adolescent and adult females do not fully manifest across all EI dimensions in early childhood. The isolated gender gap in perception points to a subtle, early divergence that warrants further tracking.

Regarding age progression, the data demonstrated robust positive associations across all developmental domains and EI metrics. As children aged from 48 to 83 months, their raw scores increased across the board. However, regression models determined that these age-related differences followed a predominantly linear trajectory rather than a complex quadratic pattern. Interestingly, when researchers controlled for general developmental factors, chronological age lost its predictive power over emotion understanding and management. This shift indicates that a child’s growing emotional competence at this stage is largely propelled by concurrent advancements in cognitive and communication resources rather than age alone.

Multivariable Predictors of Emotional Competence

To untangle the overlapping influences of age, gender, and general development, the research team conducted hierarchical stepwise regression analyses for each emotional intelligence dimension. The resulting models offered clear empirical boundaries for how cognitive and communication domains support emotional growth.

For emotion perception, age and gender entered the model first, but cognitive ability emerged as a significant independent predictor ($beta = 0.177, p = 0.004$), contributing to a final model that explained 8.1% of the total variance. Communication ability played a different role, acting as the sole independent predictor of emotion understanding ($beta = 0.181, p = 0.002$), accounting for 4.4% of the variance while washing out the direct effect of age.

Most notably, cognitive ability demonstrated the strongest predictive power for emotion management ($beta = 0.322, p < 0.001$), explaining 7.2% of additional variance above age and pushing the total explained variance for the management model to 9.6%. Motor skills, by contrast, made no unique contribution in the multivariate models, suggesting their bivariate correlations with emotional intelligence were largely shared with age and general cognition.

Educational Implications and Future Directions

The implications of these findings extend directly into early childhood classrooms. Because interpreting emotional cues, selecting regulation strategies, and understanding feelings are tied so closely to cognitive and communicative faculties, educational strategies should evolve to reflect this interconnectedness.

The study’s authors propose that early educational settings could significantly benefit from integrated curricula that weave emotional learning directly into cognitive and language-based activities. For instance, emotion recognition exercises can be structured to sharpen children’s attentional and discriminative cognitive processes. Similarly, communication-heavy, interactive storytelling can provide the linguistic scaffolding children need to articulate and process complex emotional states.

While the study’s cross-sectional design and modest overall variance explained (ranging from 4.4% to 9.6%) point to the influence of unmeasured external variables—such as parenting styles, home environments, and temperament—the research establishes a vital baseline. By proving that performance-based emotional intelligence forms an active component of broader developmental processes, the Málaga and Granada research teams have provided a foundation for future longitudinal and intervention studies aimed at optimizing socio-emotional resilience in the earliest years of education.
