In this review, we distinguish strong and weak forms of synesthesia. Strong synesthesia is characterized by a vivid image in one sensory modality in response to stimulation in another one. Weak synesthesia is characterized by cross-sensory correspondences expressed through language, perceptual similarity, and perceptual interactions during information processing. Despite important phenomenological dissimilarities between strong and weak synesthesia, we maintain that the two forms draw on…

Neuroscience of synesthesia and cross-modal associations
This review summarizes and reflects current knowledge concerning synesthesia in its various aspects, including its cognitive, neural, and behavioral aspects.
The Cognitive Processing Models of Synesthesia and Its Neuropsychological Mechanisms
Synesthesia is the simultaneous perception of different senses. There are strong synesthesia and weak synesthesia, with the former referring to explicit consciousness of a second sense perception and

By first appreciating the similarities between normal sensory perception and synesthesia, one can use what is known about synaesthesia, from behavioral and imaging studies, to inform the understanding of “normal” sensory perception.
Synesthesia, Then and Now
Puzzling in its diversity and resistant to simple theoretical accounts, synesthesia has been a subject of scrutiny and investigation for more than a century. Over 30 years ago, the present author

Synesthesia, the conscious, idiosyncratic, repeatable, and involuntary sensation of one sensory modality in response to another, is a condition that has puzzled both researchers and philosophers for

Synesthesia: A Union of the Senses
For decades, scientists who heard about synesthesia hearing colors, tasting words, seeing colored pain just shrugged their shoulders or rolled their eyes. Now, as irrefutable evidence mounts that
Synaesthesia: Prevalence and Familiality
There are no reliable prevalence or sex-ratio figures for synaesthesia, which is essential for establishing if the reported sex ratio (female bias) is reliable, and if this implicates a sex-linked genetic mechanism.

Pain affect encoded in human anterior cingulate but not somatosensory cortex.
These findings provide direct experimental evidence in humans linking frontal-lobe limbic activity with pain affect, as originally suggested by early clinical lesion studies.
Surreptitious observation of responses to hypnotically suggested hallucinations: a test of the compliance hypothesis.
Suggestions for arm levitation and for visual, auditory, tactile, and taste hallucinations were administered to a group of high suggestible students and low suggestible simulators and indicate that the responses of suggestible individuals reflect internally generated changes in experience and are not due to simple intentional compliance.
Perceiving similarity and comprehending metaphor.
Children of all ages and adults matched pitch to brightness and loudness to brightness, thereby showing that even very young children recognize perceptual similarities between hearing and vision.
Cross-modal equivalence in early infancy: Auditory–visual intensity matching.
It has been proposed that young infants are attentive to quantitative variations in stimulation to the exclusion of qualitative ones. To the extent that this is so, young infants should ignore

The results suggest that partly strategic and partly mandatory components may constitute overall performance and three alternative explanations of the color-pitch interaction--perceptual, semantic, and response based--are evaluated.
Dimensional interaction between color and pitch
In three experiments I investigated the nature of cross-modal dimensional interaction by testing speeded classification of the synesthetically corresponding dimensions of color (white-black) and
