“…Cada etapa evolutiva del sujeto tiene unas características determinadas frente al desempeño de tareas creativas, de esta manera, tal desempeño no es igual en el niño que en el adulto, y a su vez se manifiestan diferencias entre las edades similares, puesto que, la experiencia brinda más elementos para producir alternativas más elaboradas y novedosas, aunque también podrían obedecer al uso de diferentes estrategias (Privodnovaa y Volf, 2016). Por otra parte, se manifiesta que la creatividad puede disminuir notablemente durante la vejez, aunque, no antes de los 70 años pues es durante el lapso de los 40 hasta los 70 años donde se estabiliza el pensamiento divergente, aun, cuando la producción creativa no tenga esta misma medida, se reconoce que durante la vejez el desempeño creativo general puede disminuir (Palmiero et al, 2014), aunque, de igual manera esto depende de variables como la salud, la cognición, la actitud, el tipo de tarea, nivel educativo, el dominio,… (por ejemplo, Elisondo y Donolo, 2018).…”

edad, haciendo especial énfasis en las diferencias que se presentan entre cada etapa evolutiva del desarrollo humano, comprobando si existe disminución de esta capacidad a lo largo de la vida. Se realizó una revisión bibliográfica en las bases de datos, Web of Science, Scopus y PsycINFO, tomando en cuenta publicaciones realizadas entre 2010 y 2017 en español o inglés. Se seleccionaron 25 artículos que se analizaron en base a diferentes características como los instrumentos empleados. Los resultados muestran heterogeneidad en los hallazgos y se discuten los resultados tratando de arrojar luz sobre la comprensión de los mismos.

“…The frequency-band specificity of the creativity-related functional connectivities that we observed in this study requires further discussion. Several EEG studies using power spectrum analysis have shown enhancements of neural activity in the alpha band during the performance of creative tasks (Grabner et al, 2007;Fink et al, 2009;Privodnova and Volf, 2016;Privodnova et al, 2017). Using event-related synchronization methods, Grabner et al (2007) and Fink et al (2009) revealed that alphaband activity becomes significantly stronger in the right cerebral cortex during divergent thinking tasks.…”

“…Accumulating evidence suggests that high creativity leads to mental well-being in older individuals (Flood and Scharer, 2006;Flood and Phillips, 2007;Roskos-ewoldsen et al, 2008;Leon et al, 2014;Palmiero et al, 2014Palmiero et al, , 2017, which resulted in increased interest in the role of the neural activity underpinning creative functions in the aging process (Ueno et al, 2015;Privodnova and Volf, 2016;Privodnova et al, 2017;Privodnova, 2018;Adnan et al, 2019). Early studies on creativity and aging found an agerelated decline in creative ability (Alpaugh and Birren, 1977;McCrae et al, 1987), while more recent findings suggest the long-term preservation of creative activity by the aging process (Roskos-ewoldsen et al, 2008;Leon et al, 2014;Palmiero et al, 2014Palmiero et al, , 2017.…”

In older participants engaged in creative tasks, Privodnova and Volf (2016) and Privodnova et al (2017) found task-related enhancements of theta activity in anterior brain areas in the initial stage of task performance, and in the final stage, taskrelated enhancement of alpha activity in the parieto-occipital area and reduction of beta activity in posterior areas. An fMRI study on creative activity and aging revealed that during creative tasks, the functional connectivity of the brains of older participants with high creativity increased significantly, including that of the default network (Adnan et al, 2019).…”

Despite growing evidence that high creativity leads to mental well-being in older individuals, the neurophysiological bases of creativity remain elusive. Creativity reportedly involves multiple brain areas and their functional interconnections. In particular, functional magnetic resonance imaging (fMRI) is used to investigate the role of patterns of functional connectivity between the default network and other networks in creative activity. These interactions among networks play the role of integrating various neural processes to support creative activity and involve attention, cognitive control, and memory. The electroencephalogram (EEG) enables researchers to capture a pattern of band-specific functional connectivity, as well as moment-to-moment dynamics of brain activity; this can be accomplished even in the resting-state by exploiting the excellent temporal resolution of the EEG. Furthermore, the recent advent of functional connectivity analysis in EEG studies has focused on the phase-difference variable because of its fine spatio-temporal resolution. Therefore, we hypothesized that the combining method of EEG signals having high-temporal resolution and the phase synchronization analysis having high-spatio-temporal resolutions brings a new insight of functional connectivity regarding high creative activity of older participants. In this study, we examined the resting-state EEG signal in 20 healthy older participants and estimated functional connectivities using the phase lag index (PLI), which evaluates the phase synchronization of EEG signals. Individual creativity was assessed using the S-A creativity test in a separate session before the EEG recording. In the analysis of associations of EEG measures with the S-A test scores, the covariate effect of the intelligence quotient was evaluated. As a result, higher individual S-A scores were significantly associated with higher node degrees, defined as the average PLI of a node (electrode) across all links with the remaining nodes, across all nodes at the alpha band. A conventional power spectrum analysis revealed no significant association with S-A scores in any frequency band. Older participants with high creativity exhibited Nobukawa et al.Phase Synchronization With High Creativity high functional connectivity even in the resting-state, irrespective of intelligence quotient, which supports the theory that creativity entails widespread brain connectivity. Thus, PLIs derived from EEG data may provide new insights into the relationship between functional connectivity and creativity in healthy older people.

“…Additionally, due to their larger vocabulary, (2) older adults should be more accurate in deciding on the plausibility of a presented solution during encoding. Similarly, following a study showing a broader semantic knowledge of older compared to young participants ( Privodnova and Volf, 2016 ), we further hypothesized that (3) older adults may have an advantage in solving new items during the memory test, reflected by higher solution rates for new CRA items. On the other hand, the young have higher cognitive flexibility and can access their knowledge faster in addition to faster average reaction times (e.g., Kray and Lindenberger, 2000 ).…”

Several cognitive functions show a decline with advanced age, most prominently episodic memory. Problem-solving by insight represents a special associative form of problem-solving that has previously been shown to facilitate long-term memory formation. Recent neuroimaging evidence suggests that the encoding network involved in insight-based memory formation is largely hippocampus-independent. This may represent a potential advantage in older adults, as the hippocampus is one of the earliest brain structures to show age-related volume loss and functional impairment. Here, we investigated the potential beneficial effects of learning by insight in healthy older (60–79 years) compared to young adults (19–28 years). To this end, we compared later memory performance for verbal riddles encoded incidentally via induced insight-like sudden comprehension in both age groups. We employed a variant of the Compound Remote Associate Task (CRAT) for incidental encoding, during which participants were instructed to judge the solvability of items. In a 24-h delayed surprise memory test, participants attempted to solve previously encountered items and additionally performed a recognition memory test. During this test, older adults correctly solved an equal proportion of new CRA items compared to young adults and both age groups reported a similar frequency of Aha! experiences. While overall memory performance was better in young participants (higher proportion of correctly solved and correctly recognized old CRA items), older participants exhibited a stronger beneficial effect of insight-like sudden comprehension on later recognition memory for CRA items. Our results suggest that learning via insight might constitute a promising approach to improve memory function in old age.
