Four studies investigated how general mental imagery might be involved in mediating the phenomenon of 'synaesthetic' spatial forms - i.e., the experience that sequences such as months or numbers have spatial locations. In Study 1, people with spatial forms scored higher than controls on visual imagery self-report scales. This is consistent with the(More)
Two experiments compared the SNARC effect for calendar months (January-December) in 16 normal controls against four participants reporting a common but little-studied variety of synaesthesia where ordinal sequences are explicitly experienced in elaborate spatially extended patterns (spatial forms). The SNARC effect (spatial-numerical association of response(More)
We first describe how the concept of "fringe consciousness" () can characterise gradations of consciousness between the extremes of implicit and explicit learning. We then show that the NEO-PI-R personality measure of openness to feelings, chosen to reflect the ability to introspect on fringe feelings, influences both learning and awareness in the serial(More)
Sequence-space synaesthesia is a type of visuo-spatial imagery in which numbers or calendar units are experienced to occupy locations in space. Previous studies have claimed that these synaesthetes (1) have stronger self-reported visual (but not spatial) imagery and (2) perform unusually well on mental rotation tasks that are usually taken to reflect(More)
In the current paper, we first evaluate the suitability of traditional serial reaction time (SRT) and artificial grammar learning (AGL) experiments for measuring implicit learning of social signals. We then report the results of a novel sequence learning task which combines aspects of the SRT and AGL paradigms to meet our suggested criteria for how implicit(More)
In response to concerns with existing procedures for measuring strategic control over implicit knowledge in artificial grammar learning (AGL), we introduce a more stringent measurement procedure. After two separate training blocks which each consisted of letter strings derived from a different grammar, participants either judged the grammaticality of novel(More)
Sequence-space synesthetes experience some sequences (e.g., numbers, calendar units) as arranged in spatial forms, i.e., spatial patterns in their mind's eye or even outside their body. Various explanations have been offered for this phenomenon. Here we argue that these spatial forms are continuous with varieties of non-synesthetic visuospatial imagery and(More)
Spatial forms are a salient, common, but poorly understood individual difference in the conscious representation of sequences such as numbers, days, months, or historical dates. For some people, thinking about members of one of these sequences is involuntarily accompanied by the additional visuo-spatial experience that the sequence member occupies a precise(More)
For many people, thinking about certain types of common sequence – for example calendar units or numerals – elicits a vivid experience that the sequence members occupy spatial locations which are in turn part of a larger spatial pattern of sequence members. Recent research on these visuospatial experiences has usually considered them to be a variety of(More)
