People often make use of a spatial “mental time line” to represent events in time. We investigated whether the eyes follow such a mental time line during online language comprehension of sentences that refer to the past, present, and future. Participants' eye movements were measured on a blank screen while they listened to these sentences. Saccade direction revealed that the future is mapped higher up in space than the past. Moreover, fewer saccades were made when two events are simultaneously taking (...) place at the present moment compared to two events that are happening in different points in time. This is the first evidence that oculomotor correlates reflect mental looking along an abstract invisible time line during online language comprehension about time. Our results support the idea that observing eye movements is likely to “detect” invisible spatial scaffoldings which are involved in cognitively processing abstract meaning, even when the abstract meaning lacks an explicit spatial correlate. Theoretical implications of these findings are discussed. (shrink)

Clinical reports suggest that children with autism spectrum disorder (ASD) struggle with time perception, but few studies have investigated this. This is the first study to examine these children’s understanding of before and after. These temporal conjunctions have been argued to require additional cognitive effort when conjoining two events in a clause order that is incongruent with their order in time. Given the suggested time perception impairment and well-established cognitive deficits of children with ASD, we expected them to have difficulties (...) interpreting temporal conjunctions, especially in an incongruent order. To investigate this, the interpretation of before and after in congruent and incongruent orders was examined in 48 children with ASD and 43 typically developing (TD) children (age 6–12). Additional tasks were administered to measure Theory of Mind (ToM), working memory (WM), cognitive inhibition, cognitive flexibility, IQ, and verbal ability. We found that children with ASD were less accurate in their interpretation of temporal conjunctions than their TD peers. Contrary to our expectations, they did not have particular difficulties in an incongruent order. Furthermore, older children showed better overall performance than younger children. The difference between children with ASD and TD children was explained by WM, ToM, IQ, and verbal ability, but not by cognitive inhibition and flexibility. These cognitive functions are more likely to be impaired in children with ASD than in TD children, which could account for their poorer performance. Thus, the cognitive factors found to affect the interpretation of temporal language in children with ASD are likely to apply in typical development as well. Sufficient WM capacity and verbal ability may help children to process complex sentences conjoined by a temporal conjunction. Additionally, ToM understanding was found to be related to children’s interpretation of temporal conjunctions in an incongruent order, indicating that perspective taking is required when events are presented out of order. We conclude from this that perspective-taking abilities are needed for the interpretation of temporal conjunctions, either to shift one’s own perspective as a hearer to another point in time, or to shift to the perspective of the speaker to consider the speaker’s linguistic choices.

This article introduces the theory of cognitive spacetime. This account allows us to go beyond the space–time dichotomy that is commonly employed in psychology and cognitive science. Linguistic analysis and experimental review is provided to support the notion that what is commonly referred to as spatial cognition (or mental space) in the cognitive sciences always contains time, and that what is commonly referred to as temporal cognition (or mental time) always contains space. For “spatial cognition” the term object-spatiotemporal cognition (or (...) object spacetime) and for “temporal cognition” the term event-spatiotemporal cognition (or event spacetime) is introduced. In order to exemplify the virtue of the new spacetime account (with its two subdomains, object spacetime and event spacetime) with a specific example, it is investigated how this new notion can substantially refine our understanding of space–time conceptual metaphor. A new conceptual-metaphor spacetime typology for cognitive processing underlying fictive motion and non-fictive motion is also proposed. Implications of the new spacetime account are discussed for metaphorically mapped mental perspective, metaphorically mapped embodiment, and cognitive science in general. Finally, specific reasons are given why the current proposal of cognitive spacetime cannot be equated with the concept of spacetime in modern physics. (shrink)
