SINCE I addressed a preliminary memoir to you on this subject,1 so much curious matter has reached me that I trust you will permit me to state my views afresh, and to deduce some inferences. Many of my readers do not and cannot visualise, and few have the habit in a pronounced degree. I must, however, beg them not to consider their own minds as identical with those of every other sane and healthy person. Psychologists ought to inquire into the mental habits of other men with as little prejudice… Expand
Images of numbers, or “when 98 is upper left and 6 sky blue”
TLDR
The authors first review Galton's observations, and then present their own, and discuss the relevance of these visuo-spatial representations of numbers in relation to contemporary debates on number representation and calculation. Expand
Not all synesthetes are alike: spatial vs. visual dimensions of sequence-space synesthesia
TLDR
A possible systematization for one area of these individual differences—the visual and spatial qualities of SSS is explored, suggesting this can help to classify synesthetes as experimental participants and perhaps explain some inconsistencies in published data. Expand
Effects of synaesthetic colour and space on cognition
A small proportion of the population experiences synaesthesia, in which a stimulus (the inducer) causes a percept (the concurrent) in its own sensory domain, and in another domain, or anotherExpand
Visualising numerals: An ERPs study with the attentional SNARC task
TLDR
It is shown that imagining the position of Arabic numbers on a horizontal mental number line speeds up the detection of targets appearing at corresponding positions in visual space, and imagery enhanced electrophysiological activity in the extrastriate cortex contralateral to the imagined number position. Expand
Czym jest liczba
The concept of number is an abstract concept. Numbers do not exist itself in the nature. On the other hand, they carry a wide variety of significant information about the environment and are presentExpand
The role of numerical magnitude and order in the illusory perception of size and brightness
TLDR
It is suggested that, while only numerical magnitude, and not letters, elicits a bias in size perception, the concurrent processing of magnitude and brightness does not bring about the same illusion, supporting the idea of a relative independence in the processing of these two dimensions. Expand
Anomalous perception in synaesthesia: A cognitive neuroscience perspective
TLDR
The latest findings on synaesthesia are reviewed, and its possible genetic, neural and cognitive bases are considered, and a neurocognitive framework for understanding anomalous perceptual experiences is proposed. Expand
Numbers and space: a cognitive illusion?
TLDR
The view that the core representation of number meaning is spatially organized as a mental number line seems to operate in a categorical fashion (“small/large”), and to be congruent with the assumption that relatively large numbers are associated with the right side of a mental representational space. Expand
The impact of visuo-spatial number forms on simple arithmetic
TLDR
If people with number forms rely more heavily on visual-spatial strategies than verbal ones then multiplication may be disproportionately affected by this strategy relative to subtraction, and this was found. Expand
A foundation for savantism? Visuo-spatial synaesthetes present with cognitive benefits
TLDR
The study shows that time-space synaesthetes' performance was superior to the control population in every assessment, but was not superior in tasks that do not draw upon abilities related to their mental calendars. Expand
