ABSTRACT

Introduction: Spelling is an essential foundation for reading and writing. However, many children leave school with spelling difficulties. By understanding the processes children use when they spell, we can intervene with appropriate instruction tailored to their needs. Methods: Our study aimed to identify key processes (lexical-semantic and phonological) by using a spelling assessment that distinguishes different printed letter strings/word types (regular and irregular words, and pseudowords). Misspellings in the test from 641 pupils in Reception Year to Year 6 were scored using alternatives to binary correct versus incorrect scoring systems. The measures looked at phonological plausibility, phoneme representations and letter distance. These have been used successfully in the past but not with a spelling test that distinguishes irregularly spelled words from regular words and pseudowords. Results: The findings suggest that children in primary school rely on both lexical-semantic and phonological processes to spell all types of letter string, but this varies depending on the level of spelling experience (younger Foundation/Key stage 1 and older Key stage 2). Although children in younger year groups seemed to rely more on phonics, based on the strongest correlation coefficients for all word types, with further spelling experience, lexical processes seemed to be more evident, depending on the type of word examined. Discussion: The findings have implications for the way we teach and assess spelling and could prove to be valuable for educators.

ABSTRACT

BACKGROUND: Despite the fact that literacy instruction is a main focus of primary education, many children struggle to meet nationally set standards. AIMS: We aimed to test which components of a comprehensive reading programme (ABRACADABRA: https://eur03.safelinks.protection. OUTLOOK: com/?url=https%3A%2F%2Fdoi.org%2F10.1186%2FISRCTN18254678&data=04%7C01%7Cjanet.vousden%40ntu.ac.uk%7C880280e0b00749df855308d94068a0bb%7C8acbc2c5c8ed42c78169ba438a0dbe2f%7C1%7C0%7C637611640381216902%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=%2B4U9sGfofkyCPEY7lWz8n3TPoMOAeJMXyFwdhW6EpUw%3D&reserved=0) mediated the effect of the programme on nationally assessed literacy outcomes. SAMPLE: Following blind allocation, 516 Year 1 pupils from 40 schools were randomized to the programme group, and 908 Year 1 pupils, to a control condition. METHODS: Pupils in the programme completed 20 weeks of instruction in grapheme/phoneme knowledge, decoding, and comprehension. Control children received regular classroom instruction. RESULTS: Children in the programme group were significantly better at these taught skills after the programme finished (effect sizes: grapheme/phoneme knowledge, ß = .33, 95% CI [0.09-0.57]; decoding, ß = .26, 95% CI [0.09-0.43]; and comprehension, ß = .26, 95% CI [0.05-0.47]). Improvements in the programme group's decoding and comprehension skills fully mediated the improvements in national literacy assessments serving as a delayed post-test 12 months after the programme. Programme group pupils were 2.3 (95% CI [1.4-4.1]) times more likely to achieve/exceed the expected standard in reading, and 1.8 (95% CI [1.2-2.6]) times more likely to achieve/exceed the expected standard in writing due to an increase in the trained skills. CONCLUSIONS: These results provide strong evidence that a programme that incorporates decoding and comprehension instruction for typically developing beginning readers improves distal educational outcomes in reading and writing through increasing proficiencies targeted by the reading programme.

ABSTRACT

Debates concerning the types of representations that aid reading acquisition have often been influenced by the relationship between measures of early phonological awareness (the ability to process speech sounds) and later reading ability. Here, a complementary approach is explored, analyzing how the functional utility of different representational units, such as whole words, bodies (letters representing the vowel and final consonants of a syllable), and graphemes (letters representing a phoneme) may change as the number of words that can be read gradually increases. Utility is measured by applying a Simplicity Principle to the problem of mapping from print to sound; that is, assuming that the "best" representational units for reading are those which allow the mapping from print to sounds to be encoded as efficiently as possible. Results indicate that when only a small number of words are read whole-word representations are most useful, whereas when many words can be read graphemic representations have the highest utility.

ABSTRACT

Classical amnesia involves selective memory impairment for temporally distant items in free recall (impaired primacy) together with relative preservation of memory for recency items. This abnormal serial position curve is traditionally taken as evidence for a distinction between different memory processes, with amnesia being associated with selectively impaired long-term memory. However recent accounts of normal serial position curves have emphasized the importance of rehearsal processes in giving rise to primacy effects and have suggested that a single temporal distinctiveness mechanism can account for both primacy and recency effects when rehearsal is considered. Here we explore the pattern of strategic rehearsal in a patient with very severe amnesia. When the patient's rehearsal pattern is taken into account, a temporal distinctiveness model can account for the serial position curve in both amnesic and control free recall. The results are taken as consistent with temporal distinctiveness models of free recall, and they motivate an emphasis on rehearsal patterns in understanding amnesic deficits in free recall.

ABSTRACT

Patients with schizophrenia display numerous cognitive deficits, including problems in working memory, time estimation, and absolute identification of stimuli. Research in these fields has traditionally been conducted independently. We examined these cognitive processes using tasks that are structurally similar and that yield rich error data. Relative to healthy control participants (n = 20), patients with schizophrenia (n = 20) were impaired on a duration identification task and a probed-recall memory task but not on a line-length identification task. These findings do not support the notion of a global impairment in absolute identification in schizophrenia. However, the authors suggest that some aspect of temporal information processing is indeed disturbed in schizophrenia.
