The "Aesthetic" of the Blues Aesthetic

This study of the “Blues Aesthetic” both supplements and revises the now-dominant socio-aesthetic paradigm by introducing the perspectives of cognitive aesthetics to African-American vernacular literary criticism. New methods of scansion, informed by literary and linguistic prosody, are developed to measure previously neglected or misclassified innovations in verse practice. Chapter 1 argues that the versificational structures of the blues tradition, enriched by African-diasporic technique, cannot be measured adequately by existing systems of English prosody. Chapter 2 identifies figures of speech that developed during plantation slavery and considers their legacy in African-American literary verse. Chapter 3 examines the often-counterintuitive influence of racial caricature on the verse practices of black writers and performance artists in the blues tradition. Chapter 4, which builds on these insights, reassesses the formal practices of blues poets. Chiastic polyrhythms, blues-sonnet hybrids, and experimental uses of 12-bar phrasing are discovered and evaluated. Finally, several now-forgotten or misconstrued advances in vernacular aesthetic theory are recuperated. What emerges from this far-reaching intervention is a more interdisciplinary, stylistically complex, and demographically diverse map of the blues tradition as a category of literary art

Quantifying ADHD classroom inattentiveness, its moderators, and variability: a meta-analytic review

Background: Most classroom observation studies have documented significant deficiencies in the classroom attention of children with attention-deficit/ hyperactivity disorder (ADHD) compared to their typically developing peers. The magnitude of these differences, however, varies considerably and may be influenced by contextual, sampling, diagnostic, and observational differences. Methods: Meta-analysis of 23 between-group classroom observation studies using weighted regression, publication bias, goodness of fit, best case, and original metric analyses. Results: Across studies, a large effect size (ES =.73) was found prior to consideration of potential moderators. Weighted regression, best case, and original metric estimation indicate that this effect may be an underestimation of the classroom visual attention deficits of children with ADHD. Several methodological factors-classroom environment, sample characteristics, diagnostic procedures, and observational coding schema-differentially affect observed rates of classroom attentive behavior for children with ADHD and typically developing children. After accounting for these factors, children with ADHD were on-task approximately 75% of the time compared to 88% for their classroom peers (ES = 1.40). Children with ADHD were also more variable in their attentive behavior across studies. Conclusions: The present study confirmed that children with ADHD exhibit deficient and more variable visual attending to required stimuli in classroom settings and provided an aggregate estimation of the magnitude of these deficits at the group level. It also demonstrated the impact of situational, sampling, diagnostic, and observational variables on observed rates of on-task behavior. © 2007 The Authors

Are children with ADHD predominantly inattentive and combined subtypes different in terms of aspects of everyday attention?

The validity of the DSM-IV subtypes is a recurring diagnostic debate in attention deficit/hyperactivity disorder (ADHD). Laboratory measures, such as the test of everyday attention for children (TEA-Ch) can help us address this question. TEA-Ch is a test battery covering different aspects of everyday attention relating to selective and sustained attention and attentional control. The aim of the current study was to investigate whether this instrument can differentiate between combined (ADHD-C) and inattentive subtype (ADHD-I) of ADHD. Subjects were recruited from a multidisciplinary ADHD outpatient unit and tested free of medication. Sixty-four children with a diagnosis of ADHD were included (38 with ADHD-C; 26 with ADHD-I). The control group was 76 children recruited from primary and secondary schools. Children with ADHD performed worse than controls on 6 out of 9 TEA-Ch subtests. However a regression analysis revealed that TEA-Ch subtests made only a marginal contribution to the correct classification of ADHD, once the effects of IQ and age are controlled. Confirmatory factor analysis in our ADHD group demonstrated that the three factor structure achieved a poor fit. More detailed analysis suggested that inferior performance on the tasks designed to test vigilance was not the result of deficient-sustained attention. ADHD-C and ADHD-I showed very few differences across tasks. In conclusion, our results provided not much support for the value of the ADHD-C and ADHD-I distinction in predicting difficulties in everyday attention.<br/

Sleep habits in children with attention-deficit/hyperactivity disorder predominantly inattentive type and associations with comorbid psychopathology symptoms

OBJECTIVES: Much of what is currently known about the sleep functioning of children with attention-deficit/hyperactivity disorder (ADHD) is based on samples of children with ADHD Combined Type, and no study to date has examined the association between sluggish cognitive tempo (SCT) and sleep functioning in children diagnosed with ADHD. Accordingly, the objectives of this study were to (1) describe the sleep habits of children diagnosed with ADHD Predominantly Inattentive Type (ADHD-I), and (2) examine whether comorbid internalizing, oppositional, and/or sluggish cognitive tempo (SCT) symptoms are associated with poorer sleep functioning in children with ADHD-I. This study extends the current literature by using a large, clinical sample of children with ADHD-I to examine the association between SCT and other psychopathology symptoms with children’s sleep functioning. METHODS: Participants were 147 children (ages 6–11; 59% male; 55% White) diagnosed with ADHD-I using a semi-structured diagnostic interview. Parents completed measures assessing their child’s sleep habits as well as comorbid anxiety, depression, oppositionality, and SCT symptoms. RESULTS: Fourteen percent of children obtain less sleep than recommended and 31% have a sleep onset latency of greater than 20 minutes. The few children taking medication for ADHD had a longer sleep onset latency than unmedicated children. Twenty-seven percent of parents indicated that it is “difficult” to get their child out of bed on school days and 41% of parents indicated that their child needs to catch-up on sleep on the weekend “at least a little”. Regression analyses found anxiety and SCT sleepy/tired symptoms to be the most consistent dimensions of psychopathology associated with sleep functioning, with little support for depression or oppositionality being associated with sleep. CONCLUSIONS: A sizeable minority of children with ADHD-I experience impaired sleep. Comorbid anxiety, in addition to SCT sleepy/tired symptoms, were most consistently associated with poorer sleep functioning in children with ADHD-I. Importantly, SCT daydreaming and SCT working memory symptoms were unassociated with sleep functioning, and the size of the effects between SCT sleepy/tired and sleep functioning indicates that these are not overlapping constructs. Longitudinal studies are needed to evaluate the interrelations of sleep problems and comorbid psychopathology symptoms and their impact on the daytime functioning of children with ADHD-I
