ERPs and morphological processing: the N400 and semantic composition

Both behavioral and electrophysiological evidence suggests that fluent readers decompose morphologically complex words into their constituent parts. Previous event-related potential (ERP) research has been equivocal with regard to whether the N400 component indexes morphological decomposition or the integration of the products of decomposition, a process called semantic composition. In a visual lexical decision task with college students, we recorded ERPs to a well-controlled set of words and nonwords made up of bound morphemes (discern, predict; disject, percern) or free morphemes (cobweb, earring; cobline, bobweb) and monomorphemic control words and nonwords (garlic, minnow; gartus, buzlic). For each of the three morphological types, participants were faster to respond to words than to nonwords. Furthermore, for each of the three morphological types, the amplitude of the N400 was more negative to nonwords than to matched words, an effect indicating that the N400 is more sensitive to the lexicality of the whole stimulus than to the meaningfulness of the constituent parts of the stimulus. The N400 lexicality effect was not significantly different across the three morphological types. To our knowledge, this is the first ERP study to directly compare the processing of printed sets of words composed of bound and free morphemes and monomorphemic control stimuli in order to explore the relative sensitivity of the N400 to morphological decomposition (i.e., the status of the parts) and semantic composition (i.e., the status of the whole). Our findings are consistent with an interpretation of the N400 as an index of a process of semantic composition.     

Social dominance orientation predicts drive for muscularity among British men

The present study tested the hypothesis that men's drive for muscularity would be associated with their valuation of domination, power, status, and aggression over others. A community sample of 359 men from London, UK, completed measures of drive for muscularity, social dominance orientation, right-wing authoritarianism, trait aggression, and need for power, as well as their demographic details. Bivariate correlations showed that greater drive for muscularity was significantly correlated with most of the measures and their subscales. However, in a multiple regression analysis, the only significant predictor of drive for muscularity was support for group-based dominance hierarchies (Adj. R² = .17). These results suggest that men's drive for muscularity is associated with a socio-political ideology that favours social dominance.     

Conscious Evolution of Humanity: Using Systems Thinking to Construct Agoras of the Global Village. Announcing the 47th Annual Conference 2003 of the International Society for the Systems Sciences (ISS) www.isss.org

This article outlines the spiritual principles shared by Integral Science and the emerging Integral Spirituality. It includes a brief overview of past changes in spiritual consciousness, the role of science in the current shift, and why various beliefs are coalescing into a new Integral Spirituality. The author then explores the causes and possible effects of these changes, concluding that the motivations and transformations must come from a synthesis of all fields.     

Predicting Women's Persistence in Adult Literacy Classes with Dispositional Variables

Adult literacy programs offer individuals, particularly women, opportunities to improve their educational levels and economic circumstances; however, persistence in these programs is an issue for many. Two hundred forty five participants in a statewide adult literacy program took the Adult Education Persistence Scale, a measure of self-efficacy, resilience, attitudes toward school, and attributions, a measure we developed in an effort to identify dispositional variables that predict persistence. Results indicated that dispositional variables modestly predicted persistence, identifying high and low attendees with 69% accuracy. We recommend screening for dispositional variables to identify those at risk for dropout and to provide relevant support.     

Profiles of Three Preservice ESOL Teachers' Development of Instructional Scaffolding

This study explored English as a second language (ESOL) preservice teachers’ conceptions of and abilities to provide scaffolded instruction. In-depth study of three interns indicated that each was unique with respect to their views of scaffolding and in the degree to which their implementation of scaffolded instruction changed over the course of the year. Participants differed in the focus of scaffolding and in their attempts to scaffold within lesson frameworks, across sequential lessons, and through responsive instruction. Though some preservice teachers can develop complex conceptions of the process, scaffolding is closely linked to interns’ understanding of language and literacy development.     

Treatment of Adolescent Panic Disorder: A Nonrandomized Comparison of Intensive Versus Weekly CBT

This study compared the relative efficacy of intensive versus weekly panic control treatment (PCT) for adolescent panic disorder with agoraphobia (PDA). Twenty-six adolescents participated in weekly sessions and 25 received intensive treatment involving daily sessions. Both groups demonstrated significant and comparable reductions in panic disorder severity and general anxiety symptoms, which maintained over time. Participants receiving weekly treatment showed significant decreases in depressive symptoms, whereas those in the intensive program reported no change. Findings support the efficacy of the intensive approach for adolescent PDA, but suggest that adolescents receiving intensive treatment may benefit from a brief course of additional weekly sessions.     

A Decline in Creativity? It Depends on the Domain

Earlier studies using psychometric tests have documented declines in creativity over the past several decades. Our study investigated whether and how this apparent trend would replicate through a qualitative investigation using an authentic nontest measure of creativity. Three-hundred and fifty-four visual artworks and 50 creative writing works produced by adolescents between 1990–1995 and 2006–2011 were assessed. Products were analyzed using a structured assessment method based on technical criteria and content elements. Criteria included in the current investigation (e.g., genre, medium, stylistic approach) are relevant both to the specific media domains and to previously established dimensions of creativity, such as originality and complexity. Results showed strong domain differences: performance in visual arts increased on a variety of indices of complexity and technical proficiency, and performance in writing decreased on indices related to originality and technical proficiency. Findings highlight the value of analysing creativity across domains. The importance of considering cultural and technological changes in characterizing and understanding apparent trends in amount and types of creativity is discussed.     

Memory of myself: Autobiographical memory and identity in Alzheimer's disease

A number of theories posit a relationship between autobiographical memory and identity. To test this we assessed the status of autobiographical memory and identity in 20 individuals with Alzheimer's disease (AD) and 20 age‐matched controls, and investigated whether degree of autobiographical memory impairment was associated with changes in identity. Two tests of autobiographical memory (Autobiographical Memory Interview, autobiographical fluency) and two measures of identity (Twenty Statements Test, identity items of the Tennessee Self Concept Scale) were administered. AD participants exhibited significant impairments on both memory tests, and changes in the strength, quality, and direction of identity relative to controls. Impairments of some components of autobiographical memory, particularly autobiographical memory for childhood and early adulthood, were related to changes in the strength and quality of identity. These findings support the critical role of early adulthood autobiographical memories (16–25 years) in identity, and suggest autobiographical memory loss affects identity.     

The Effects of Hand Gestures on Verbal Recall as a Function of High- and Low-Verbal-Skill Levels

The author examined the effects of cueing for verbal recall with the accompanying self-generated hand gestures as a function of verbal skill. There were 36 participants, half with low SAT verbal scores and half with high SAT verbal scores. Half of the participants of each verbal-skill level were cued for recall with their own gestures, and the remaining half was given a free-recall test. Cueing with self-generated gestures aided the low-verbal-skill participants so that their retrieval rate equaled that of the high-verbal-skill participants and their loss of recall over a 2-week period was minimal. This effect was stable for both concrete and abstract words. The findings support the hypothesis that gestures serve as an auxiliary code for memory retrieval.
