As Time Goes By: Car Radio and the Travel Experience in Twentieth-Century America
Since its invention nearly a century ago, the car radio has found its way into over ninety-five percent of vehicles on the road. Modern day radio programming is tailored to suit a mobile audience, and many listeners view car radios as an essential part of the driving experience. Yet within the scope of scholarly studies on this subject, the questions addressed are so focused on the mechanical problems of how radios were integrated into automobiles that there is substantially less research examining why radios were first imported into the car. What was the inspiration for such a combination? And how did it affect the travel experience for car users?
Expanding upon current scholarship related to mobile sound technologies and their influence on the experience of mechanized travel, I argue that the conditions individually brought about by the radio and the automobile mutually reinforced one another: both worked together to alter the perceived passage of time and space for their users. Given that these developments directly reflect similar shifts in the perception of space and time occurring with the invention of older travel technologies such as the railroad half a century earlier, the application of radio to the car can be understood as just one more manifestation of the new spatiotemporal paradigm gripping the post-industrial West in the first half of the twentieth century
The phonological representations hypothesis of dyslexia : consequences for the formation of associations
Linking memory and language : Evidence for a serial-order learning impairment in dyslexia
The present study investigated long-term serial-order learning impairments, operationalized as reduced Hebb repetition learning (HRL), in people with dyslexia. In a first multi-session experiment, we investigated both the persistence of a serial-order learning impairment as well as the long-term retention of serial-order representations, both in a group of Dutch-speaking adults with developmental dyslexia and in a matched control group. In a second experiment, we relied on the assumption that HRL mimics naturalistic word-form acquisition and we investigated the lexicalization of novel word-forms acquired through HRL. First, our results demonstrate that adults with dyslexia are fundamentally impaired in the long-term acquisition of serial-order information. Second, dyslexic and control participants show comparable retention of the long-term serial-order representations in memory over a period of one month. Third, the data suggest weaker lexicalization of newly acquired word-forms in the dyslexic group. We discuss the integration of these findings into current theoretical views of dyslexia.Peer reviewedFinal Accepted Versio
Encoding order and developmental dyslexia:a family of skills predicting different orthographic components
We investigated order encoding in developmental dyslexia using a task that presented nonalphanumeric visual characters either simultaneously or sequentially—to tap spatial and temporal order encoding, respectively—and asked participants to reproduce their order. Dyslexic participants performed poorly in the sequential condition, but normally in the simultaneous condition, except for positions most susceptible to interference. These results are novel in demonstrating a selective difficulty with temporal order encoding in a dyslexic group. We also tested the associations between our order reconstruction tasks and: (a) lexical learning and phonological tasks; and (b) different reading and spelling tasks. Correlations were extensive when the whole group of participants was considered together. When dyslexics and controls were considered separately, different patterns of association emerged between orthographic tasks on the one side and tasks tapping order encoding, phonological processing, and written learning on the other. These results indicate that different skills support different aspects of orthographic processing and are impaired to different degrees in individuals with dyslexia. Therefore, developmental dyslexia is not caused by a single impairment, but by a family of deficits loosely related to difficulties with order. Understanding the contribution of these different deficits will be crucial to deepen our understanding of this disorder

The phonological representations hypothesis of dyslexia : consequences for the formation of associations
Orthographic context and the acquisition of orthographic knowledge in normal and dyslexic readers
We tested the hypothesis that the acquisition of orthographic knowledge of novel words that are presented in an indistinct context, that is a context with many orthographically similar words, would be more difficult for dyslexic than for normal readers. Participants were 19 Dutch dyslexic children (mean age 10;9 years), 20 age-matched and 20 reading-age-matched normal readers. During training the children repeatedly read a series of nonwords in a distinct (KWOG with KWES and SNAR) and an indistinct (KWOG with KWOS and KROG) orthographic context. At posttest, the dyslexic children were slower but more accurate in the reading of nonwords if these had been acquired in an indistinct than in a distinct training context. In normal readers context did not have an effect. We argue that dyslexic children's sensitivity to orthographic context is due to their problems in the acquisition of fully specified orthographic representations causing interference by similar words
Word, nonword and visual paired associate learning in Dutch dyslexic children
Verbal and non-verbal learning were investigated in 21 8-11-year-old dyslexic children and chronological-age controls, and in 21 7-9-year-old reading-age controls. Tasks involved the paired associate learning of words, nonwords, or symbols with pictures. Both learning and retention of associations were examined. Results indicate that dyslexic children had difficulty with verbal learning of both words and nonwords. In addition, analysis of the errors made during nonword learning showed that both phonological errors and general learning errors were distributed similarly for the reading groups. This suggests that nonword learning in dyslexics is slower, but not qualitatively different from normal readers. Furthermore, no differences were found between the dyslexics and age-matched normal readers on non-verbal learning. Long-term retention of the learned visual verbal associations (both words and nonwords) was not impaired in dyslexic children as compared to normal readers. Finally, phonological awareness ability was assessed. It was found that dyslexics performed worse than age-matched normal readers, but similar to reading-age controls.
