This study explores the concept of spiritual intelligence from an evolutionary perspective, providing a comprehensive and updated definition. A concept analysis was conducted following Rodgers’ Evolutionary Method, supported by a scoping review in accordance with the Joanna Briggs Institute methodology. Studies explicitly addressing spiritual intelligence, regardless of population, setting, or discipline, were included across quantitative, qualitative, mixed-methods, and review designs. Four databases—PsycINFO, PubMed Central, Scopus, and Web of Science—were searched for publications up to 15 December 2025, using the term “spiritual intelligence.” One-hundred-twelve articles met inclusion criteria and were analyzed through narrative synthesis and inductive analytical processing. Spiritual intelligence emerged as a construct encompassing adaptive cognition, higher consciousness, problem management, and personal growth, often referred to as Spiritual Quotient or Existential Intelligence. Antecedents included self and transcendental awareness, existential questioning, and search for meaning and purpose, while consequents comprised enhanced health, performance, self-awareness, and humanitarian orientation. Defining attributes were equanimity, life-wisdom, transcendental awareness, spiritual consciousness, meaning and purpose creation, and existential questioning. This evolutionary analysis traced the concept from theory to application, revealing its positive influence in daily life. Equanimity and life-wisdom were identified as core attributes, highlighting implications for training and integration of spiritual care in professional practice.

The ATHENA (Advanced Tool for Holistic Evaluation and Nurturing of Abilities) competency framework proposes a multidimensional approach to human performance structured around five interdependent dimensions (cognition, conation, knowledge, emotion, and sensori-motion), operationalized through 60 fine-grained facets. Although ATHENA is grounded in contemporary psychological theory and supported conceptually by multivariate research in intelligence, creativity, and skill acquisition, empirical evidence regarding the clarity and practical comprehensibility of its facets remains limited. This study investigates the extent to which instructional designers and human resource development (HRD) professionals—two groups who routinely operationalize competencies for learning, assessment, and workforce development—understand and evaluate the semantic clarity and usability of the 60 facets. Seventy-five practitioners completed a structured evaluation of the ATHENA framework facets, which are designed to be used in a hybrid intelligence system for competency management. This article presents the theoretical background, methodological design, and results concerning users’ comprehension of the framework’s components. The findings support, in general, the compatibility of ATHENA’s facets and practitioners’ conceptions.

Working memory capacity (WMC) has long served as a central indicator of individual differences in complex cognition. However, growing evidence suggests that a substantial portion of its predictive power may reflect attention control (AC)—including goal maintenance, interference management, and inhibition—rather than storage capacity alone. This review synthesizes findings across six domains: (1) perception and sensory discrimination, (2) learning and problem solving, (3) cognitive control and decision making, (4) retrieval and memory performance, (5) multitasking and real-world performance, and (6) clinical applications. Across these areas, WMC-related effects frequently align with demands on AC, though the strength and nature of this alignment vary by domain. We highlight the importance of incorporating reliable AC measures and recommend latent-variable approaches to more clearly separate storage, control, and representational processes underlying complex performance.
