The nature of phonological processing in oral reading: Evidence from surface dyslexia

Investigation of a neurological patient (PT) who presents with a relatively pure disorder of reading was carried out. His performance on a number of oral reading tasks was very similar to that of the surface dyslexic patient (HTR) reported by Shallice, Warrington and McCarthy (1983). Both patients showed an effect of “degree” of regularity in terms of accuracy of reading response. PT did not, however, show an effect of “typicality of divergence”, which was considered by Shallice and his colleagues to be responsible for the former effect. The size of orthographic-phonological unit operational in PT's oral reading was experimentally determined. PT appeared to rely on grapheme-phoneme correspondences that were assigned in a probabilistic rather than an “all-or-none” manner. No evidence for the existence of the sub-syllable as an independent unit was found. In contrast, this unit apparently mediated the performance of skilled adult readers. Implications of these results for models of the phonological route are discussed.     

Prior Health Care Utilization Patterns and Suicide Among U.S. Army Soldiers

Suicides among U.S. Army soldiers are increasing and, in January 2009, outpaced deaths due to combat. For this study, 1,873 army suicides identified through death, inpatient, and emergency room records were matched with 5,619 controls. In multivariate models, older, male, White, single, and enlisted soldiers with a prior injury (OR = 2.04, 95% CI = 1.64‐2.54), alcohol (OR = 3.41, 95% CI = 2.32‐4.99), or mental health hospitalization (OR = 6.62, 95% CI = 4.77‐9.20) were at increased risk for suicide. Risk was greatest immediately following diagnoses, but remained elevated even after 5 or more years of follow‐up. Most injury hospitalizations were unintentional but, nonetheless, significantly associated with suicide. Interactions indicate soldiers with both mental health and injury history are particularly vulnerable.     

Attentional set in pure- versus mixed-lists in a dichotic listening paradigm

An experiment was designed to assess the contribution of attentional set to performance on a forced choice recognition task in dichotic listening. Subjects were randomly assigned to one of three conditions: speech sounds composed of stop consonants, emotional nonspeech sounds, or a random combination of both. In the groups exposed to a single class of stimuli (pure-list), a REA (right ear advantage) emerged for the speech sounds, and a LE (left ear advantage) for the nonspeech sounds. Under mixed conditions using both classes of stimuli, no significant ear advantage was apparent, either globally or individually for the speech and nonspeech sounds. However, performance was more accurate for the left ear on nonspeech sounds and for the right ear for speech sounds, regardless of pure versus mixed placement. The results suggest that under divided attention conditions, attentional set influences the direction of the laterality effect.     

TEXT COMPREHENSION RESEARCH TO CLASSROOM APPLICATION: DEVELOPING AN INSTRUCTIONAL TECHNIQUE

Abstract

Reading comprehension skills are routinely taught and they are often learned to a point of “mastery” on criterion referenced tests; but students relatively seldom apply them effectively when they read content‐area materials. In this paper we argue that the problem can best be solved not by abandoning skill‐centered teaching but by discovering ways to help students make effective use of the skills they acquire through skill‐centered instruction. Our approach is to develop procedures for glossing expository text; that is, we are using marginal and other intratext notations‐‐gloss‐‐to direct students’ attention while they read in order to help them internalize, direct, and apply specific skills and strategies. We describe the purpose and rationale for our developmental approach and show how we are attempting to bring research implications to bear on our work.
