meditationKozhevnikov, Louchakova, Josipovic, & Motes (2009) examined the effects of meditation on mental imagery, evaluating Buddhist monks’ reports concerning their extraordinary imagery skills. Practitioners of Buddhist meditation were divided into two groups according to their preferred meditation style: Deity Yoga (focused attention on an internal visual image) or Open Presence (evenly distributed attention, not directed to any particular object). Both groups of meditators completed computerized mental-imagery tasks before and after meditation. Their performance was compared with that of control groups, who either rested or performed other visuospatial tasks between testing sessions. The results indicate that all the groups performed at the same baseline level, but after meditation, Deity Yoga practitioners demonstrated a dramatic increase in performance on imagery tasks compared with the other groups. The results suggest that Deity meditation specifically trains one’s capacity to access heightened visuospatial processing resources, rather than generally improving visuospatial imagery abilities.

Maria Kozhevnikov was featured in the Association for Psychological Science press release announcing her paper: The Enhancement of Visuospatial Processing Efficiency Through Buddhist Deity Meditation.

Visual-Spatial Processing in Different Domains

Our research on visual-spatial processing in different domains follow three directions:

In our research, we investigate visualization processing and visual representations in different specialization domains such as physics and visual art. A separate line of research examined visualization in meditation, and its the effects on mental imagery abilities, evaluating Buddhist monks’ reports concerning their extraordinary imagery skills.

The research in the Mental Imagery lab focuses on investigating visualization processes and individual differences in mental imagery in cognitive style. In particular, we examine how individual differences in visualization ability affect more complex activities, such as spatial navigation, learning and problem solving in mathematics, science and art. We also explore ways to train visual-object and visual-spatial imagery skills and design three-dimensional immersive virtual environments that can accommodate individual differences and learning styles.

The Mental Imagery and Human-Computer Interaction lab research focuses in five main directions:

Our approach integrates qualitative and quantitative behavioral research methods, as well as neuroimaging techniques (EEG, fMRI). Furthermore, we develop and validate assessment and training paradigms for visualization ability, using  3D immersive virtual reality.

Based on behavioral and neuroscience evidence, we formulated a theoretical framework of individual differences in visual imagery, and suggested that visualization ability is not a single undifferentiated construct, but rather is divided into two main dimensions: object and spatial, and that the spatial dimension is further divided into allocentric and egocentric dimensions. All these visualization abilities underlie success at different complex, real-world tasks, and predict specialization in different professional and academic domains.
