This study examines the interaction between two types of synesthesia: ordinal linguistic personification (OLP; the involuntary association of animate qualities such as gender/personality to linguistic units such as letters/numbers/days) and grapheme-color synesthesia (the involuntary association of colors to letters and/or numbers). By examining both variants in the same individual we aim to: (a) show that features of different synesthetic variants interact in cognitive tasks, (b) provide a… Expand
Ordinal Linguistic Personification as a Variant of Synesthesia
TLDR
It is argued that these shared characteristics of OLP suggest a unified underlying behavior, and propose OLP as a subtype of synesthesia. Expand
Implicit versus explicit interference effects in a number-color synesthete
TLDR
It is argued that distinguishing synesthesia from learned synesthesia-like associations (pseudosynesthesia) should depend primarily on the presence of subjective reports, validated by objective measures, and that consciously and unconsciously mediated interference may arise from qualitatively different mechanisms. Expand
Synesthesia and memory: color congruency, von Restorff, and false memory effects.
TLDR
Findings are consistent with the idea that color-grapheme synesthesia can lead people to place a greater emphasis on item-specific processing and surface form characteristics of words in a list relative to relational processing and more meaning-based processes. Expand
When Blue is Larger than Red: Colors Influence Numerical Cognition in Synesthesia
TLDR
It is shown that colors do implicitly evoke numerical magnitudes in color-grapheme synesthetes, but not in nonsynesthetic participants, and it is proposed that bidirectional co-activation of brain areas is responsible for the links between color and magnitude processing incolor-grapevine synesthesia and that unidirectional models of synesthesia might have to be revised.

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
Bidirectionality in synesthesia: evidence from a multiplication verification task.
TLDR
The current findings add two important notions to previous studies: (a) the influence of color on the processing of numerical information can be extended to multiplication verification tasks and (b) the perception of color can both facilitate and interfere with theprocessing of digit-related information.

Social responsiveness to inanimate entities: Altered white matter in a ‘social synaesthesia’
TLDR
This study is the first to show that unusual differences in white matter microstructure in these regions is associated with compelling feelings of social cohesion and personality towards non-animate entities, linking language and personality attributes in this surprising way. Expand
Reflections on Synesthesia, Perception, and Cognition
In this paper, we reflect on three long-standing problems: The relationship between the physical world and the perceived world, accounting for individual differences in the way in which we perceiveExpand
Cross-modal personality attributions in synaesthetes and non-synaesthetes.
Those variants of synaesthesia that trigger colour are well studied, although comparatively less is known about variants that involve cognitive constructs such as personality types. Here weExpand
Synaesthesia and Individual Differences
Synaesthesia is a fascinating cognitive phenomenon where one type of stimulation evokes the sensation of another. For example, synaesthetes might perceive colours when listening to music, or tastesExpand

Synaesthesia? A window into perception, thought and language
We investigated grapheme–colour synaesthesia and found that: (1) The induced colours led to perceptual grouping and pop-out, (2) a grapheme rendered invisible through ‘crowding’ or lateral maskingExpand
An Investigation of the Cognitive and Perceptual Dynamics of a Colour–Digit Synaesthete
TLDR
The clear pattern of response-time differences between L and the control group suggests that tasks designed to produce involuntary divisions of attention can be an effective means by which to demonstrate that synaesthetic experiences are involuntary but elicited. Expand
Unconscious priming eliminates automatic binding of colour and alphanumeric form in synaesthesia
TLDR
It is concluded that automatic binding of colour and alphanumeric form in synaesthesia arises after initial processes of letter and digit recognition are complete and that synaesthetic experiences can be prevented despite substantial processing of the sensory stimuli that otherwise trigger them. Expand
What is the relationship between synaesthesia and visuo-spatial number forms?
TLDR
The presence of synaesthetic colour sensations enhances the tendency to explicitly represent numbers in a visuo-spatial format although the two symptoms may nevertheless be logically independent (i.e. it is possible to have number forms without colour, and coloured numbers without forms). Expand
Synesthesia: when colors count.
TLDR
Evidence for an implicit co-activation of digits by colors is found in a random color generation task, a finding that constrains neurological theories concerning cross-modal associations in general and synesthesia in particular. Expand
Neurocognitive Mechanisms of Synesthesia
TLDR
Debates in the field relating to the neural basis of synesthesia are focused on, including the relationship between synesthesia and attention and the role of meaning in synesthetic colors. Expand
The perceptual reality of synesthetic colors
TLDR
The subject, in contrast to non-synesthetic subjects, accomplished the task with relative ease because the target of the search had a different synesthetic color from the distractors, indicating that synesthetic experiences appear to originate from a binding of color and form that takes place within central stages of visual processing. Expand
A systematic, large-scale study of synaesthesia: implications for the role of early experience in lexical-colour associations
TLDR
It is suggested that the development of lexical-colour synaesthesia in many cases incorporates early learning experiences common to all individuals, and that the learning of such sequences during an early critical period determines the particular pattern of lexicals-colour links and that this pattern then generalises to other words.
