Mnemonic devices may help brain-injured patients

Mnemonics are devices that allows for classification, organization, storage and recollection of information into and out of long-term memory. In Ancient Rome, orators used mnemonics to remember the points they wanted to make in a speech. The method of remembering they used is called the Method of Loci, invented by the Greek poet Simonides about 500 B.C. Simonides was asked to recite a poem at a banquet, given by one of his patrons, and after doing so the room fell in, burying all in its debris, and disfiguring the bodies so as to render identification impossible. Simonides, however, had noted the position each guest had occupied, and was thus able to point out the remains of each. (A.E. Middleton, All About Mnemonics, London, 1885).

Modern neurosciences have showed that effectiveness of visual imagery mnemonics like Method of Loci is based on the human capability to remember objects when they are placed in a visual structured context. The literature on the use of visual imagery as a mnemonic device has consistently shown that subjects who use visual imagery to help them learn verbal material do considerably better than subjects who attempt to learn the material using simple rote repetition. Brain imaging research has shown that when visual imagery is used to learn verbal material, subjects show brain activity in systems normally involved in processing visual stimuli. The implications of these findings point to the potential learning advantage of a complex imagination.

There is clinical evidence that visual imagery mnemonics are particularly useful in remediation of memory disorders in brain-damaged patients. In particular, research suggests that such techniques can lead to improved performance on formal testing in a number of neurologic disease populations and following lesions of either the left or right hemisphere.

2006 South African Conference on Positive Psychology

2006 South African Conference on Positive Psychology will be taking place in April of next year. The aim of the conference is to provide an update on theory, measurement and application in the domain of positive psychology in general, and in particular as pertains individual, social and work wellness in a multi-cultural context.

Does technology make us happy?

In this comment recently posted on Doors of Perception, design guru John Thackara criticizes EU's r&d programmes. According to Thackara, these programmes are too much technology-focused and don't put societal challenges at their centre. I fully agree with Thackara's criticism. My own experience with IST projects is that proposals that don't make technology the starting point have little chance of success...

 

As designers and social innovators, should we take any notice of technology policy? Wouldn't it be best to ignore the think-tanks and telcos, and concentrate on doing great projects in the real world? A 90% focus on projects would probably be healthy. But we also need to keep half an eye on policy making because that's where priorities for research spending - and hence the projects we are able to do - are made.
Tech policy is not a pretty picture right now. After a few years in which social issues were visible on the agenda, tech-push is fighting back. In the European Union, for example, the Information Society Technologies (IST) programme contains a lot of tech but not much soc. The IST's aim is to 'master technology and its applications, and help strengthen industrial competitiveness'. Documents mention the need to 'address the main European societal challenges' - but the advisory group that interprets that statement, ISTAG, consists wholly of Big Tech and Big Research interests. (To compound the imbalance, ISTAG comprises 29 men and just four women). There once existed a panel of High-Level Socio-Economic Experts but they quietly disappeared in 2003, supplanted by an entity called eEurope. The main job of eEurope is to 'develop modern public services and a dynamic environment for e-business through widespread availability of broadband access at competitive prices and a secure information infrastructure'. Once again: a lot about tech and not much about soc
