Thereβs a lovely experiment from 1929 (Jersild) that compares the effectiveness of common speaking techniques--(or "vividness devices" (67)--on the retention of meaningful information including slowing down and repetition.
Contrary to common habit, speaking slowly is ineffective, because βno active review of a statement can take place until the last word has been spoken, since not until then will the content of the statement be known.β (68) That is, people process and understan

Whilst researching on the extended mind, I came upon this passage by Plato on writing, knowledge and memory

Saccades are the voluntary movements of the eyes which serve to bring a new part of the visual field into the foveal region. Saccadic eye movements can reveal global aspects of perception, such as the scan patterns and fixation locations of subjects inspecting human faces.

At the heart of cognitive science is the notion of a representation: How the mind represents the world during perception and how we relate to these representations when we think.
Representations are the objects of thought, the building blocks of mental experience. Representations have been considered imagist

Mock-up of what Phylomon might look like.
I'm intrigued by The Phylomon Project. In the year of biodiversity, the Science Creative Quarterly (SCQ) are compiling a bunch of cards with the key statistics of species on them, emulating Pokemon. Apparently primary school kids can remember 120+ types of Pokemon creatures, but know less than 50% of common wildlife species. My concern with the project is that they have missed out on the fun.

Slide from Eric Mazur's lecture, "Confessions of a Converted Lecturer"[.pdf]
On Thursday 14th January I attended a lecture "Confessions of a Converted Lecturer"[.pdf], by physicist and learning pioneer, Eric Mazur at the University of Queensland. Mazur says:
I thought I was a good teacher until I discovered my students were just memorizing information rather

In my previous blog post I discussed Locke's CommonPlace book and information overload in the 16th century. Now, my attention turns to what we use today.
Whilst Google manages our common knowledge extremely well, it does not help us remember the most basic and arguably important data for success, people's names.

Locke's Common-place book
Between 1500-1700 the amount of available knowledge increased dramatically and the lack of an ordered system for cataloging this information frightened scholars [1]. Initially ideas were grouped together in notebooks by subject, but this system was supplanted by Locke's new method, that indexed memorable ideas via alphabetic order, rather than by relevant heading. This method increased one's capacity to store ideas whilst simultaneously reducing search

In the recent Extended Mind debate, it can be easy to forget how long discussions of 'artificial' memory have been in existence. I don't normally quote great swathes of text, but this single sentence from 1200AD, expresses such a richness of content that I couldn't resist:

The Dream, Henri Rosseau, (1910) MoMA
Source Monitoring was first described as a framework for understanding how people attribute the source of mental experiences in 1993 (Johnson, Hastroudi & Lindsay, see also Johnson & Raye). The Source Monitoring Framework (SMF) has been used by many labs in the last 15 years to investigate how the subjective experience affects memory judgments. Features that make up complex e

Sleep
A recent Harvard experiment (Payne et. al., 2009) shows that an afternoon nap selectively increases false recall of semantically similar critical words to presented words [see DRM paradigm]. This is because sleep plays an active rather than a merely passive role in memory consolidation. Upon waking, experimenters found that subjects remember the gist of the presented items more easily than specific words,

Figure 1: Imagining a healing white light might actually precipitate the body's own capacity to deliver pain relief (e.g. opioids), but won't reduce the size of a cancerous tumour.
Placebo-activated opioids, for example, not only relieve pain; they also modulate heart rate and respiration. The neurotransmitter dopamine, when released by placebo treatment, helps improve motor function in Parkinson's patients. Mechanisms like these can elevate mood, sharpen cognitive ability, allevi

Helen Keller is famous for being a tremendously successful deaf, blind and mute writer and activist. She is also central to one of the most famous cases of cryptomnesia, a circumstance when a person utilizes implicit information whilst experiencing no phenomenal familiarity with the content. In this case, Helen wrote the story The Frost King and was accused of plagiarizing The Frost Fairies by Margaret Canby.
In the history of analytic philosophy, there is much debate abo

TITLE: The Danger of the Extended Mind
ABSTRACT: This paper accepts three claims of the Extended Mind Hypothesis (EMH): 1) External elements form part of the machinery of cognition, insofar as they causally interact with mental states. 2) The meaning of our thoughts is partly explained by reference to the external world (content e

...it’s very important to use your brain, to keep challenging your mind, but all mental activities may not be equal. We’re seeing some evidence that a social component may be crucial... The evidence suggests that people who spend long stretches of their days, three hours and more, engrossed in some mental activities like cards may be at reduced risk of developing dementia. Researchers are trying to tease apart cause from effect: Are they active because they are sharp, or sharp be

The Waters of Lethe, Thomas Benjamin Kennington
...the river of Unmindfulness, whose water no vessel can hold; of this they were all obliged to drink a certain quantity, and those who were not saved by wisdom drank more than was necessary; and each one as he drank forgot all things. Plato
