1. Introduction
Effectively managing talent has become crucial for organizations worldwide, serving as a key tool to gain a competitive advantage through human capital
. While the term 'talent' universally denotes a special natural ability or aptitude that sets individuals apart, the ongoing discourse among scholars centers on the dichotomy of innate versus acquired talent

. This critical debate not only shapes our understanding of the origin and development of talents but also underscores the complexity surrounding their definition and measurement in various fields. Recent theories propose a more nuanced perspective, suggesting that talents emerge through a complex interaction between inherent predispositions and environmental factors, introducing a continuum range from innate to acquired

. The correlation between brain activity and talents has been a subject of investigation, particularly with the advent of modern neuroscience techniques like EEG (Electroencephalogram) and fMRI (functional Magnetic Resonance Imaging)
. The human brain, comprised of over 100 billion neurons, communicates through electrical signals, giving rise to brain waves of different frequencies

The research presented aims to answer the following questions: Can neuroscience give us an indication of where our talents/abilities reside in the brain? Does expressing a talent mean activating a specific area of our brain? Our hypothesis is that there are significant correlations between the talents acted by the subjects and the EEG tracks. We chose to compare results obtained by the SEI test and the EEG measurements. The study concentrated on subject belonging to different working roles: the social/healthcare and non-healthcare (or administrative) workers. We believe this could be a useful tool both in the recruitment phase and in the training activities aimed at increasing talents/skills in subjects’ employees in organizational roles.
2. Materials and Methods
2.1. The Brain Talent Profile, SEI
This test is grounded in the Six Seconds model of Emotional Intelligence, a tripartite model developed in 1997 by Peter Salovey) and John Mayer
[29] | Mayer, J D & Salovey, P (1997). What is emotional intelligence? In P. Salovey & D. Sluyter (Eds). Emotional Development and Emotional Intelligence: Implications for Educators (pp. 3-31). New York: Basic Books. |
[29]
. One way to assess the reliability of a scale (a set of items in a questionnaire) is to calculate the internal consistency of the factors within it. Internal consistency measures how closely the items included in the scale are related to each other. Cronbach's Alpha coefficient was also used to calculate the reliability of the factors comprising the SEI. This index ranges from -1 to +1, and a coefficient with a positive value greater than 0.6 is considered statistically reliable in research.
2.2. Neuroanatomical Correlates Detection
Participants were asked to engage in various brief activities, such as watching a video and responding to questions, while performing these activities, they wore an EEG headband, suitable for both neurofeedback and brain activity measurements, in medical and psychological contexts. To improve conductivity and maintain high hygiene standards, a sponge soaked in a solution of water and alcohol was used between each electrode and the scalp. After mounting the headband and confirming that the signal was clear with no interference due to excessive hair or a sebum-rich scalp at the electrode sites, which could compromise signal detection, participants were instructed to relax, sit comfortably, and prepare for the beginning of the activities. The instrument has four channels, dry electrodes, a sampling frequency of 250 Hz, and a voltage range of ±0.4 V. It collects data that can be converted and interpreted using the BrainBit Inc. software, Version 2.2.15. The analysis was conducted by cross-referencing the Brain Brief Profile (BT) profiles with the responses to the questions and EEG measurements for each subject. During the research, the Brain Talent Profile was employed, along with three custom-prepared activities and the BrainBit EEG signal detection headband.
2.3. Experimental Operations
The research activities took place on March 14 and 15, 2022, at Villa Fiorita, a location made available by the Piccola Opera Charitas Foundation of Giulianova. The experimental operations were conducted in a room with a closed door, equipped with two workstations, tables, and chairs, to allow the four researchers to conduct EEG readings during the administration of the three tasks described earlier. Participants entered the room at scheduled times, and each operation on a participant lasted for about twenty minutes. To capture EEG readings, the BrainBit headset was applied to each subject. Participants were encouraged to respond calmly to the tasks and not to worry about their answers. The answers were confidential and could not be disclosed externally except in anonymous aggregate form. Each response had a pre-set time of three minutes, specifically designed to record adequate brain electrical activity and promote the expression of talents that the experimental tasks aimed to elicit.
Descriptive and inferential analyses were conducted to outline the demographic and professional profiles of the participants and investigate any relationships between the use of talents in the three macro areas during task completion and the electrocortical activation of the temporal or occipital lobes of the two hemispheres. These analyses were carried out using the Jamovi software
.
3. Results
The research unfolded in three phases: the first involved subject sample selection and Brain Talent Profile questionnaire administration; the second focused on detecting neuroanatomical correlates using the BrainBit helmet, and the third encompassed data analysis and report preparation. The Brain Brief Profile comprises three areas: Perception, Evaluation, and Action. Perception involves integrating cognitive and emotional information, Evaluation assesses the balance between risks and opportunities, and Action explores the motivation balance between short and long-term goals. Each area is subdivided into two parts, namely cognitive or emotional for Perception, reflective or innovative for Evaluation, and practical or idealistic for Action. The workflow of the research is presented in
Figure 1.
Figure 1. Workflow of the project.
3.1.1. Sample Selection and Characterization Based on Age, Gender, Education, Working Role
The research involved 60 employees of the Piccola Opera Caritas of Giulianova (TE) (hereinafter FPOC) of age, sex and mixed professions. The sample is made up of people aged 22 to 63, with an average age of 43 (
Figure 2A). The subjects who participated in the research were almost equally male and female, with a slight prevalence of women (
Figure 2B). The level of education of the sample is quite high: more than 55% have a university degree, while only 10.6% have attended compulsory school (
Figure 2C). The population is perfectly heterogeneous, evenly divided into Non Healthcare workers and Healthcare workers. The majority of graduates work in the healthcare sector, while in the Non-Healthcare area, there are mainly individuals with a diploma (
Figure 2D).
3.1.2. Talent Assessment Using the Sei Questionnaire
Subsequently, each participant was presented with the SEI questionnaire, from which it was possible to compile descriptive statistics on the detected profiles (Brain Talent Profile).
From the statistical analysis of contingency between the Roles and the Talents, for each question, no meaningful values have emerged that can justify the hypothesis that there is a relation between the two variables (χ
2 between 0.5 and 1,4 and p values >0.1), (
Figure 3,
Table A1).
The first part of the analysis, the socio-demographic descriptive data of the sample and the contingency relationships between the variables Education and Roles cross-referenced with the various Talents, did not reveal any evidence suggesting that the subjects had distinctive characteristics regarding roles they held.

Evidence of Neurophysiological Correlates, and Data Analysis
In this section we analyzed the neurophysiological correlates of the subjects in the sample while they were engaged in the three activities.
Activity 1: perception
The first activity is divided into three tasks and designed to bring out the talents belonging to the macro area of Perception. The exercise is structured to discern whether subjects are utilising skills from the Rational or Emotional Perception clusters.
Task 1.0 Viewing of a television commercials of a car brand, where the protagonist had the lion’s head. From the Analysis of the Variance between the activation of the four waves, in the temporal and occipital lobes and between the right and left hemispheres, have emerged clue values for a significant difference in brain activation of subjects operating in the non Healthcare workers and Healthcare workers. In particular, significant difference in hemispheres asymmetry in the activation of the four waves was observed (p. < 0.10), which could mean a different electrical brain pattern among subjects in different occupational areas (
Figure 4A, 4D).
Task 1.1 Question answering. Detection of correlates took place while the subjects were filling out the question "What impressed you most, after viewing the first video?”. From this analysis, no values emerged that could suggest a significant difference between the roles of Healthcare and Non Healthcare workers, or in brain activation between the 59% of the subjects who expressed a talent Rational compared to 31% of the subjects who expressed themselves in an emotional manner, (
Figures 4B, 4F, Figure A1). However, there was a small significant difference in the asymmetry between the hemispheres regarding the activation of theta waves (p. 0,68) in Rational subjects, circumstance that could mean a different electrical arrangement of the brain between subjects who express themselves with different talents (
Figure 4E). Incidentally, Theta waves are activated during the state of deep sleep, but if they appear with certain intensity during wakefulness, they are a sign of empathy and openness, to unconscious processes for solving problems. In this case, the viewing of the fantastic film could have induced a brain state of this type.
Task 1.2 Question answering. Detection of correlates took place while the subjects were filling out the answer to the question: how would you describe this spot with a sentence? From the statistical analysis no values emerged that could suggest a significant difference between the roles of Healthcare and Non Healthcare workers in brain activation among 56% of the subjects who expressed a talent Rationally compared to 35% of the subjects who expressed in an Emotional way, while 9% was not clearly defined in one of the two categories (
Figures 4C, 4G, Figure A2).

(B, F); Task 1.2 Question answering: how would you describe this spot with a sentence? (C, G). Asymmetry of theta waves (E).
Activity 2: evaluation
The second activity is tailored to unveil skills within the Evaluation macro-area, specifically assessing whether the individual evaluates the situation in an Innovative or Reflective manner.
Task 2.0 Watching a video in which the protagonist finds themself stranded on Mars in a difficult situation.
The analysis of this task revealed indicative values for a significant difference in the brain activation of individuals working in the Social and Health and Administrative fields. In particular, it was observed a significant difference (p. < 0.10) in the occipital lobes with high activation in the right cerebral hemisphere, for all four electrical waves (
Figure 5A, 5D, Figure A3). This circumstance could indicate a different electrical arrangement in the brains of individuals working in different occupational areas, particularly higher in the Social and Health role when involved in tasks representing critical situations. The reported activation of the occipital lobe may be related to the dominance of the visual modality, which predominantly activates these cortical areas. However, it remains not clear whether this activation is due to the characteristics of the individuals involved or if the role has somehow accentuated these characteristics compared to the Administrative role.

Activity 2: evaluation, Task 2.0 Watching a video in which the protagonist finds themself stranded on Mars in a difficult situation (A, D); Task 2.1 Answering to the question: How do you handle this situation? (B, F); Task 2.2 Answering to the question: How did you feel in this exercise? (C, G). Electrical activity of the right temporal lobe hemisphere (E).
Task 2.1 Question answering.
The assessment of the correlates took place while the subjects were engaged in answering the question "How do you handle this situation?" after viewing the second video. From the Analysis of Variance between the activation of the four waves in the temporal and occipital lobes and between the right and left hemispheres, no values emerged that could suggest a significant difference between the Social and Health and Administrative roles or in brain activation between the 40.4% of subjects who expressed a Reflective talent compared to the 26.3% of subjects who expressed themselves in an Innovative manner (
Figure 5B, 5F, Figure A4). However, significant findings did emerge in terms of asymmetry between the cerebral hemispheres in the group consisting of 20 subjects (33.3%) for whom it was not possible to assign them to either of the two predefined categories (Reflective/Innovative) (
Figure 5B). This group of 20 subjects comprises 14 females (8 in the Administrative role and 6 in the Social and Health role) and 6 males (2 in the Administrative role and 4 in the Social and Health role). The 6 males range in age from 25 to 50 years, while the ages of the females are distributed between 30 and 62 years.
Task 2.2 Question answering. The assessment of the correlates took place while the subjects were engaged in answering the question "How did you feel in this exercise?", after viewing the second video and responding to question 2.1. From the Analysis of Variance between the activation of the four waves in the temporal and occipital lobes and between the right and left hemispheres in relation to Talents, values emerged that could suggest a significant difference in brain activation between the 40.4% of subjects who expressed a Reflective talent and the remaining 26.3% of subjects who expressed themselves in an Innovative manner, and 33% who were not assigned to any category (
Figure 5C, G). The Reflective individuals showed greater activation of three out of the four waves (excluding Delta, a circumstance not explainable based on the available data) in the temporal lobe of the right hemisphere (as inferred from the positive sign of the mean indicating the right hemisphere, while the negative sign is related to the left hemisphere (
Figure 5E).

The subjects were engaged in reading an episode presenting a situation in which he/she must decide what to do regarding an incident that puts them in conflict between reporting an employee who has embezzled money from the company or keeping it silent (A, D); Answering to the question: what do you do, after reading the passage describing a critical situation? (B, F). Task 3.2 Answering to the question: and for what reasons?" after reading the passage describing a critical situation and responding to question 3.1 (C, F). Electrical activity of the right occipital lobe hemisphere (E).
Activity 3: action
The third activity of the research delves into the “Action” area, focusing on identifying which areas of practical or idealistic talents individuals deploy when taking action. This segment comprises three tasks to explore different facets of participants’ action-oriented skills.
Task 3.0 reading a scenario involving a conflict situation. The subjects were engaged in reading an episode presenting a situation in which he/she must decide what to do regarding an incident that puts them in conflict between reporting an employee who has embezzled money from the company or keeping it silent. Notably, during this task, distinct values emerged in the brain activation patterns of subjects in Administrative and Social/Health fields. Significant differences in the right cerebral hemisphere were observed across all four electrical waves (p < 0.10), suggesting a potential variation in the electrical arrangement of the brain based on occupational roles. This disparity was particularly pronounced in individuals with roles in Social and Health settings when confronted with decision-making tasks in conflict situations (
Figure 6A, 6D).
Task 3.1 Question answering. The subjects were engaged in answering the question "What do you do?", after reading the passage describing a critical situation. From the analysis values emerged that could suggest a significant difference in brain activation among the 52.6% of subjects expressing a Practical talent, compared to the 33.3% expressing an Idealistic talent, and the 14% who were not clearly classified into either category. In particular, the analyses highlight that subjects expressing a Practical talent exhibit greater, statistically significant (p<0.01) activation in the occipital lobe, with higher activation in the right hemisphere (as inferred from the positive sign of the mean indicating the right hemisphere, while the negative sign is related to the left hemisphere) in all four electrical waves (
Figure 6E). There is also a unique observation related to the activation of Delta waves in the parietal lobe in subjects classified as "unclassified," which could be explained by a brain configuration associated with deeper and more open problem-solving thinking (
Figure 6B, 6F).
Task 3.2 Question answering. The subjects were engaged in answering the question "And for what reasons?" after reading the passage describing a critical situation and responding to question 3.1. The data analysis revealed values that could suggest a significant difference in brain activation among subjects expressing a Practical or Idealistic talent, or were not clearly classified into either category (
Figure 6C, 6F). In particular, subjects expressing a Practical talent exhibit greater activation in the occipital lobe, with higher activation in the right hemisphere (
Figure 6E). There is also a unique observation related to the activation of Delta waves in the parietal lobe in subjects classified as "unclassified," similar to the findings in question 3.1.
4. Conclusions
The present research successfully addressed the initial question that prompted the study: whether different neurophysiological correlates are associated with the enactment of various talents. Two hypotheses were explored: the “null” hypothesis positing no differences in brain activation across different talents, indicating no significant distinctions in EEG patterns regardless of the task or talent. Conversely, the “alternative” hypothesis advocates that the expression of diverse talents would trigger distinct electrocortical patterns.
The research project was meticulously structured, enabling sample subjects to demonstrate a spectrum of talents within six distinct macro areas. This was achieved through their responses to stimulus tasks designed to elicit varied mental patterns, allowing for a comprehensive examination of potential differences.
The analysis of responses has uncovered profiles that align with the alternative hypothesis, indicating that the execution of specific talents elicits distinct electrocortical patterns. Particularly, in the first task involving watching a car brand’s TV commercial with a protagonist having a lion’s head, asymmetrical activation between cerebral hemispheres was noted, with greater activation in the right occipital lobe. This disparity was more pronounced in the group of subjects in the Social and Health care role compared to those in the Administrative role.
Similarly, a notable difference was observed during the second task involving the viewing of a video (depicting an astronaut stranded on Mars, after a space mission) and in the third task, which involved reading a passage where subjects had to decide how to respond to a conflict situation involving an employee stealing money from the company. These three tasks, designed to activate different talents in the areas of Perception, Processing, and Action, produced distinct electrocortical patterns as anticipated by the research objectives.
An intriguing observation arose from the results of task 2.1, where 20 subjects were not classified into “Reflective” or “Innovative” talent categories. These subjects exhibited significant activation in the right temporal lobe. Qualitative analysis of their responses uncovered an inclination towards indecision, favoring explicit displays of emotional states experienced in that situation. Emotional states are known to be influenced by complex neural networks that impact brain functions. In this instance, there was substantial activation in the right hemisphere, prompting an intriguing question: Can certain emotional states create a form of brain short-circuit that inhibits decision-making?
One last finding concerns the correlation that emerged in tasks 3.1 and 3.2 (answering the questions "What do you do?" and "For what reasons?" related to the theft of money from the company's cash registers) with the EEG patterns of the right occipital lobe in the groups of Administratives who exhibited a Practical talent, possibly more inclined to make normative decisions without the intrusion of emotional or idealistic motives.
In conclusion, despite the pilot nature of the study and the need for refinement in certain broad-brush aspects for future investigations, the obtained results provide confidence in rejecting the null hypothesis. The alternative hypothesis is supported, instead, indicating clear correlations between EEG patterns and the talents exerted by the subjects.
5. Discussion
Effective job performance relies not only on skills and goodwill but also on having the right tools. Expecting professionals to rely solely on goodwill is impractical in today's complex work environments. Predisposition, talent, and experience are essential pillars for success. Beyond physical tools, “soft skills” are crucial differentiators, shaping how individuals approach their roles. Imagine a healthcare professional lacking communication and empathy or an administrative worker with creativity but lacking analytical skills – the potential outcomes in their respective roles would vary significantly. Developing and understanding these mental and character tools is crucial for success in specific roles. Ensuring that individuals are well-equipped with the necessary skills and attributes not only benefits their own professional growth but also serves as a valuable contribution to the well-being of all stakeholders involved.
The present research was carried out within and on behalf of the Piccola Opera Charitas Foundation of Giulianova (hereinafter FPOC) - director: Domenico Rega - and Six Seconds Italy - director: Lorenzo Fariselli, and it originated from the idea of Tania Cariani, EQ (Emotional Quotient) Practitioner and Assessor. It should be considered a pilot study due to several conditions that characterized the research sample, the available measurement tools, and, most importantly, the research hypotheses aimed at verifying if there is a relationship between neurophysiological patterns and "talents' ' exhibited in specific situations. Although the study maintained an exploratory approach, it successfully outlined an indicative profile of the experimental variables and offered initial insights into the research questions. Notably, the study achieved a reliable differentiation of talents among the 60 subjects in the sample, considering factors such as roles, age, and education. Additionally, it identified neurophysiological patterns, revealing how subjects exhibited distinct brain electrical activation in response to specific tasks based on both their talents and roles. The prime condition that enabled the research to be carried out was the availability, support, and cooperation of the Piccola Opera Charitas Foundation in Giulianova. They facilitated the recruitment of the 60 sample subjects with specific socio-demographic characteristics necessary for the research analysis; provided an appropriate setting for the research, by making EEG recording spaces available for two workstations staffed by four researchers. They scheduled and coordinated the 60 research subjects' appointments with researchers for the neurophysiological pattern data collection, all within a short timeframe of just one and a half days. Moreover, they provided timely and motivated cooperation of the sample subjects during the data collection operations; hospitality and cordial reception provided by the Foundation's staff to the researchers, along with continuous support throughout the research activities. In addition to these strengths, which are not all mentioned here due to space constraints, there were other factors that contributed to the successful execution of the research, such as the availability of state-of-the-art portable EEG equipment provided by the “Università Cattolica del Sacro Cuore” in Milan and the University of Pavia, as well as the expertise of the research team in data collection and neurophysiological pattern analysis, which were essential to completing such a complex scientific endeavour.
Acknowledging the positive aspects highlighted, future research could benefit from considerations beyond the pilot study. The utilization of more advanced electroencephalographic equipment, featuring 32 or 64 channels, in collaboration with university laboratories, could enhance neurophysiological pattern recordings during cognitive tasks. Doubling the sample size would contribute to greater stability and interpretability of observed variations. Implementing a “double assessment control group” design, incorporating pre and post-assessments, would capture changes resulting from specific intervention protocols applied to the experimental group. This approach, involving practical and visual activities, not only aids in mapping brain areas related to talents but also detects changes arising from experimental interventions.
The obtained findings offer encouragement for additional research, suggesting the potential for future solid evidence. This evidence could prove valuable in recruiting individuals for diverse job roles and assessing the effectiveness of training activities aimed at enhancing competencies, especially in critical organizational roles.
