“…In addition to fMRI, electroencephalography (EEG) has been used to study mental representations as expressed through electrical neural activity (e.g., Shourie et al, 2014 ). Research in object-related mental imagery using EEG is comparatively scarce, but the work that has been done has been successfully used to decode motor imagery for the purpose of brain–computer interface control (e.g., Townsend et al, 2004 ; see Choi, 2013 for review), suggesting EEG is capable of distinguishing amongst general categories of imagined actions.…”

One of the fundamental goals of object recognition research is to understand how a cognitive representation produced from the output of filtered and transformed sensory information facilitates efficient viewer behavior. Given that mental imagery strongly resembles perceptual processes in both cortical regions and subjective visual qualities, it is reasonable to question whether mental imagery facilitates cognition in a manner similar to that of perceptual viewing: via the detection and recognition of distinguishing features. Categorizing the feature content of mental imagery holds potential as a reverse pathway by which to identify the components of a visual stimulus which are most critical for the creation and retrieval of a visual representation. This review will examine the likelihood that the information represented in visual mental imagery reflects distinctive object features thought to facilitate efficient object categorization and recognition during perceptual viewing. If it is the case that these representational features resemble their sensory counterparts in both spatial and semantic qualities, they may well be accessible through mental imagery as evaluated through current investigative techniques. In this review, methods applied to mental imagery research and their findings are reviewed and evaluated for their efficiency in accessing internal representations, and implications for identifying diagnostic features are discussed. An argument is made for the benefits of combining mental imagery assessment methods with diagnostic feature research to advance the understanding of visual perceptive processes, with suggestions for avenues of future investigation.

“…Complexity measures has been used in different studies to measure levels of creativity before (Jaušovec and Jaušovec, 2000b;Shourie et al, 2014). Approximate Entropy is a measure of signal regularity which that explores the time ordering of data points by calculating the log likelihood that runs of pattern which are close remain close for incremental comparison (Pincus, 1995).…”

Two stages of the creative writing process were characterized through mobile scalp electroencephalography (EEG) in a 16-week creative writing workshop. Portable dry EEG systems (four channels: TP09, AF07, AF08, TP10) with synchronized head acceleration, video recordings, and journal entries, recorded mobile brain-body activity of Spanish heritage students. Each student's brain-body activity was recorded as they experienced spaces in Houston, Texas (“Preparation” stage), and while they worked on their creative texts (“Generation” stage). We used Generalized Partial Directed Coherence (gPDC) to compare the functional connectivity among both stages. There was a trend of higher gPDC in the Preparation stage from right temporo-parietal (TP10) to left anterior-frontal (AF07) brain scalp areas within 1–50 Hz, not reaching statistical significance. The opposite directionality was found for the Generation stage, with statistical significant differences (p < 0.05) restricted to the delta band (1–4 Hz). There was statistically higher gPDC observed for the inter-hemispheric connections AF07–AF08 in the delta and theta bands (1–8 Hz), and AF08 to TP09 in the alpha and beta (8–30 Hz) bands. The left anterior-frontal (AF07) recordings showed higher power localized to the gamma band (32–50 Hz) for the Generation stage. An ancillary analysis of Sample Entropy did not show significant difference. The information transfer from anterior-frontal to temporal-parietal areas of the scalp may reflect multisensory interpretation during the Preparation stage, while brain signals originating at temporal-parietal toward frontal locations during the Generation stage may reflect the final decision making process to translate the multisensory experience into a creative text.

“…Los datos recopilados de imágenes de resonancia magnética functional (IRMf) se han utilizado para decodificar con éxito tanto la identidad del objeto como la clasificación de categorías, no solo de estímulos percibidos visualmente, sino también de imágenes generadas mentalmente (Thirion et al, 2006;Reddy et al, 2010). Además de la técnica fMRI, la electroencefalografía (EEG) se ha utilizado para estudiar las representaciones mentales expresadas a través de la actividad neural eléctrica (por ejemplo, Shourie, Firoozabadi, & Badie, 2014). Incluso, una tecnología relativamente nueva, la espectroscopia de infrarrojo cercano funcional (fNIRS) está ganando rápidamente popularidad debido a la portabilidad y flexibilidad de la aplicación experimental.…”

Características de la imaginación en distintos campos creativos

La imaginación constituye una base importante de la vida psíquica, actúa como soporte del pensamiento e interviene en los procesos de conocimiento. Una de las características más interesantes de la imaginación es su capacidad evocadora que permite al individuo liberarse del entorno inmediato del mundo físico y construir un mundo interior distanciado de la realidad. Así podemos fantasear, soñar y crear. El objetivo de este trabajo fue hacer una revisión de los últimos descubrimientos sobre la implicación de los distintos estilos cognitivos en diferentes campos creativos. Partiendo de la definición de las imágenes mentales como fruto de imaginación, se hizo un recorrido por distintas medidas de las imágenes mentales, desde los cuestionarios subjetivos, fruto de la introspección, pasando por las medidas objetivas, ligadas fundamentalmente a habilidades espaciales, para finalizar con los métodos fisiológicos y las nuevas medidas de la neurociencia. Se dedicó un epígrafe a los estilos de procesamiento de información: Imagen de objeto, espacial y verbal, que caracterizan los tipos de imaginación en distintos ámbitos del conocimiento, y se analizaron los estudios llevados a cabo en diferentes ámbitos profesionales y titulaciones universitarias. Los resultados de estudios previos, lejos de dar respuesta a las múltiples cuestiones, abren nuevas vías de investigación, tanto acerca de la necesidad de crear nuevas medidas de habilidad de imagen, como la forma de abordar las habilidades de imagen en los distintos ámbitos.
