Gestalt principles of form perception by Mads Soegaard


Gestalt psychology attempts to understand psychological phenomena by viewing them as organised and structured wholes rather than the sum of their constituent parts. Thus, Gestalt psychology dissociates itself from the more 'elementistic'/reductionistic/decompositional approaches to psychology like structuralism (with its tendency to analyse mental processes into elementary sensations) and it accentuates concepts like emergent properties, holism, and context.
In the 30javascript:void(0)s and 40s Gestalt psychology was applied to visual perception, most notably by Max Wertheimer, Wolfgang Köhler, and Kurt Koffka who founded the so-called gestalt approaches to form perception. Their aim was to investigate the global and holistic processes involved in perceiving structure in the environment (e.g. Sternberg 1996). More specifically, they tried to explain human perception of groups of objects and how we perceive parts of objects and form whole objects on the basis of these. The investigations in this subject crystallised into "the gestalt laws of perceptual organization." Some of these laws, which are often cited in the HCI or interaction design community, are as follows....

Targeting the Brain with Sound Waves - Technology Review


Ultrasound might provide a new, noninvasive way to control brain activity.


Ultrasound waves, currently used in medicine for prenatal scans and other diagnostic purposes, could one day be used as a noninvasive way to control brain activity. Over the past two years, scientists have begun experimenting with low-frequency, low-intensity ultrasound that can penetrate the skull and activate or silence brain cells. Researchers hope that the technology could provide an alternative to more-invasive techniques, such as deep-brain stimulation (DBS) and vagus nerve stimulation, which are used to treat a growing number of neurological disorders.
