The genesis of reading ability: What helps children learn letter-sound correspondences?

Knowledge of letter-sound correspondences underpins successful reading acquisition, and yet little is known about how young children acquire this knowledge and what prior information they bring to the learning process. In this study, we used an experimental training design to examine whether either prior letter awareness or prior phonemic awareness directly assists preliterate children in subsequently learning letter-sound correspondences. Here 76 preschoolers received 6 weeks of training in either letter awareness, phonemic awareness, or control tasks and then received a further 6 weeks of training in either letter-sound correspondences or control tasks. There was limited evidence that prior training in either phoneme or letter awareness directly assisted learning of letter-sound correspondences, although phonemically trained children appeared to show some advantage on recognition tasks. Overall, the data suggest that there is little value in training preschoolers in either letter forms or sounds in isolation in advance of providing instruction on the links between the two.     

Self-esteem depends on the beholder: Effects of a subtle social value cue

The idea that self-esteem functions as a gauge or “sociometer” of social value [Leary, M. R., Baumeister, R. F. (2000). The nature and function of self-esteem: Sociometer theory. In M. P. Zanna (Ed.), Advances in experimental social psychology (Vol. 32, pp. 1-62). San Diego: Academic Press] is supported by research on direct social feedback. To examine if the sociometer model is relevant to more subtle social value cues, the implicit self-esteem of women was assessed a week after an interaction with an experimenter. Consistent with the sociometer model, Week 2 self-esteem depended on a subtle social value cue encountered during Week 1. When the Week 1 experimenter wore a t-shirt celebrating larger bodies (i.e., “everyBODY is beautiful”), heavier women had higher self-esteem than lighter women in Week 2. As hypothesized, this effect was relationship-specific, occurring only when the same experimenter administered Week 1 and 2 sessions.

How predictable is spelling? Developing and testing metrics of phoneme-grapheme contingency

Prior research has purported to show that words with infrequent phoneme-grapheme correspondences are more difficult to spell than words with frequent phoneme-grapheme correspondences. Defining exactly what a phoneme-grapheme relationship is, however, is not necessarily straightforward. There are a number of different assumptions that can be made. In this study, we developed four metrics of sound-spelling contingency based on all monosyllabic English words, including those with complex morphology. These metrics differed in the extent to which they included assumptions about spelling. The psychological reality of these different metrics was evaluated against data from a large-scale study of skilled adult spelling and a nonword spelling experiment. The results suggest that when spelling, people are sensitive to positional information, morphological status, vowel type, and a number of more idiosyncratic constraints.     

Rubinstein-Taybi syndrome.

Rubinstein-Taybi Syndrome was first described in 1957 but only in 1963 as a distinguishable type of moderate mental retardation. The cause is still unknown although some type of genetic origin is possible. No consistent chromosomal abnormality has been demonstrated, the chromosomal analysis is normal, and cases are generally not considered hereditary. The recurrent risk for siblings is approximately 0.1% but may be as high as 50% for offspring of patients with the syndrome. The Rubinstein-Taybi syndrome is not at present detectable before birth and is evenly found in both males and females. The syndrome was thought to be rare but an increase in the number of reported cases each year suggests it is not as rare as estimated. It is thought to occur in about 1 in 300,000 births, and since it has become readily identifiable, more than 400 cases have been reported worldwide.     

Educational needs of school personnel regarding child abuse and/or neglect

From a review of literature a questionnaire was developed to identify problems related to child abuse/neglect in a rural school district. School administrators, regular and special education teachers, and counselors completed the survey to help establish more effective training programs. Analysis indicated that (1) school personnel need further assistance in dealing with problems pertaining to the maltreatment of students. (2) Formal, coordinated, workshop training for child abuse/neglect is needed. (3) Colleges and universities should offer instruction on abuse/neglect for persons preparing to work in schools. (4) School personnel need to be aware of and abide by the laws regarding reporting cases of abuse/neglect. (5) Improved communication among school, community, courts, and social service agencies is required for dealing wtih abuse cases. (6) School personnel should become more aware of what happens after abuse/neglect has been reported. Information from such analysis even for one school district can increase insight into problems.     

Iconic memory: A reply to Professor Holding

Professor Holding has argued that the partial report superiority normally taken as evidence for the existence of iconic memory might instead be due to cue anticipation or output interference. I have suggested that both of these alternative explanations are inconsistent with the finding that the partial report superiority diminishes rapidly with increasing cue delay. In addition, Sperling’s original partial report experiment was designed in such a way that cue anticipation could not have occurred; and both his results with selection by letter vs number and Averbach and Coriell’s bar-marker results indicate that output interference effects are absent or negligible in tachistoscopic experiments. Consequently, I have concluded that the partial report superiority, and especially its decline with increasing delay, remains as strong evidence in favor of the conventional view of iconic memory. Furthermore, if this view were wrong, there would remain no way of giving a satisfactory account of (a) Averbach and Coriell’s results, (b) “direct” investigations of visual persistence, or (c) integration and interruption effects in backward visual masking.
