Writing skills typically develop over a course of more than two decades as a child matures and learns the craft of composition through late adolescence and into early adulthood. The novice writer progresses from a stage of knowledge-telling to a stage of knowledgetransforming characteristic of adult writers. Professional writers advance further to an expert stage of knowledge-crafting in which representations of the author's planned content, the text itself, and the prospective reader's interpretation of the text are routinely manipulated in working memory. Knowledge-transforming, and especially knowledge-crafting, arguably occur only when sufficient executive attention is available to provide a high degree of cognitive control over the maintenance of multiple representations of the text as well as planning conceptual content, generating text, and reviewing content and text. Because executive attention is limited in capacity, such control depends on reducing the working memory demands of these writing processes through maturation and learning. It is suggested that students might best learn writing skills through cognitive apprenticeship training programs that emphasize deliberate practice.

The ensemble hypothesis proposes that language is but one of five cognitive capacities that separate human cognition qualitatively from other animal cognition as a result of their interactions. The ensemble consists of an episodic memory capable of mental time travel, mentalizing to augment social cognition, language for overt communication, advanced executive attention for governing working memory, and inner speech for thinking in the form of causal inference. The order in which each of these components arose in hominin evolution is addressed here. It is proposed that the flourishing of symbolic artifacts during the Upper Paleolithic occurred because, for the first time, all five components were in place and interacting in anatomically modern Homo sapiens.

Previous studies have suggested that both automatic and intentional processes contribute to the learning of grammar and fragment knowledge in artificial grammar learning (AGL) tasks. To explore the relative contribution of automatic and intentional processes to knowledge gained in AGL, we utilized dual-task methodology to dissociate automatic and intentional grammar- and fragment-based knowledge in AGL at both acquisition and at test. Both experiments used a balanced chunk strength grammar to assure an equal proportion of fragment cues (i.e., chunks) in grammatical and nongrammatical test items. In Experiment 1, participants engaged in a working memory dual-task either during acquisition, test, or both acquisition and test. The results showed that participants performing the dual-task during acquisition learned the artificial grammar as well as the single-task group, presumably by relying on automatic learning mechanisms. A working memory dual-task at test resulted in attenuated grammar performance, suggesting a role for intentional processes for the expression of grammatical learning at test. Experiment 2 explored the importance of perceptual cues by changing letters between the acquisition and test phase; unlike Experiment 1, there was no significant learning of grammatical information for participants under dual-task conditions in Experiment 2, suggesting that intentional processing is necessary for successful acquisition and expression of grammar-based knowledge under transfer conditions. In sum, it appears that some aspects of learning in AGL are indeed relatively automatic, although the expression of grammatical information and the learning of grammatical patterns when perceptual similarity is eliminated both appear to require explicit resources.

We examined whether an automated essay feedback system could improve the writing performance of college students. Students in a freshmen composition course received no feedback or varying amounts of formative feedback on their first drafts of three practice essays (none, intermittent, or continuous). The students wrote a first and then a revised final draft of an essay in a writing lab held once per week. After a retention interval of 2 weeks, a test essay was written without the use of feedback to assess transfer of learning. Holistic scores showed no reliable gains, but the transfer test showed that students learned to reduce errors of mechanics, usage, grammar, and style. The benefit was found for continuous but not intermittent feedback. (Contains 3 tables and 1 figure.)

The development of advanced writing skills has been neglected in schools of the United States, with even some college graduates lacking the level of ability required in the workplace (National Commission on Writing, 2003, 2004). The core problem, we argue, is an insufficient degree of appropriate task practice distributed throughout the secondary and higher education curriculum. We draw on the power law of skill acquisition, the role of deliberate practice in expert performance, and the uniquely intensive demands that advanced written composition place on working memory to make this case. A major impediment to assigning enough writing tasks is the time and effort involved in grading papers to provide feedback. We close by considering possible solutions to the grading problem.

Two experiments examined whether text composition engages verbal, visual, and spatial working memory to different degrees. In Experiment 1, undergraduate students composed by longhand a persuasive text while performing a verbal, visual, or spatial concurrent task that was presented visually. In Experiment 2, participants performed a verbal or spatial concurrent task that was aurally presented. Writing performance was not disrupted differentially across the three tasks. Performance on all concurrent tasks showed fewer correct responses and longer RTs relative to single-task, baseline data. However, the demands on visual working memory were as high as those on verbal working memory, whereas demands on spatial working memory were minimal. The findings help to delineate the roles of the verbal, visual, and spatial working memory in written composition.

The contributions of verbal, visual, and spatial working memory to written language production were investigated. Participants composed definitions for nouns while concurrently performing a task which required updating, storing, and retrieving information coded either verbally, visually, or spatially. The present study extended past findings by showing the linguistic encoding of planned conceptual content makes its largest demand on verbal working memory for both low and high frequency nouns. Kellogg, Olive, and Piolat in 2007 found that concrete nouns place substantial demands on visual working memory when imaging the nouns' referents during planning, whereas abstract nouns make no demand. The current study further showed that this pattern was not an artifact of visual working memory being sensitive to manipulation of just any lexical property of the noun prompts. In contrast to past results, writing made a small but detectible demand on spatial working memory. DOI 10.2466/PMS.110.1.229-244

The ensemble hypothesis proposes that uniquely human cognitive abilities depend on more than just language. Besides overt language, inner speech, and causal interpretations, executive attention, mental time travel, and theory of mind abilities are essential parts that combine additively and even multiplicatively. In this review, we consider the implications of the ensemble hypothesis for the psychopathologies of anxiety and depression. Generalized anxiety disorder (GAD) and major depressive disorder (MDD) are two of the most common mental disorders worldwide. The mechanisms that differentiate them are difficult to identify, however. Mental time travel has been implicated in models of depressive and anxiety disorders, but here we argue that at least two other ensemble components, namely, interpreter biases and executive attention, must also be considered. Depressive and anxiety disorders have both been found to show impairments in all three of these components, but the precise relationships seem to distinguish the two kinds of disorders. In reviewing the literature, we develop models for depression and anxiety that take into account an ensemble of mental components that are unique for each disorder. We specify how the relations among mental time travel, interpreter biases, and executive attentional control differ in depression and anxiety. We conclude by considering the implications of these models for treating and conceptualizing anxiety and depression. [ABSTRACT FROM AUTHOR]

Examines whether the cognitive strategies of outlining and draft writing enhance college students' writing performance. Reports that outlines improved the quality of writing, but did not enhance efficiency. Rough drafts did not affect quality or efficiency. A survey of faculty revealed that outlines correlated positively with productivity, whereas drafting did not. (SKC)

Unilateral hand contractions increase activation in the motor cortex of the contralateral hemisphere, providing a means to alter the relative degree of activation in the right hemisphere versus the left hemisphere through spreading activation. Prior research reported enhanced verbal creativity as measured by performance on remote associate problems in Hebrew from left-hand contractions (right-hemisphere activation). We sought to extend the previous findings to English problems and to homograph interpretation. In Experiment 1, unilateral hand contractions in fact altered performance on the English remote associates, but in the direction of improved performance following right-hand contractions and left-hemisphere activation. In Experiment 2, the probability of retrieving atypical interpretations of homographs with multiple meanings was least likely for left-hemisphere dominant strong right handers, but the hand contraction manipulation had no effect.

The career of metaphor hypothesis suggests that novel metaphors are understood through a search for shared features between the topic and vehicle, but with repeated exposure, the figurative meaning is understood directly as a new category is established. The categorization hypothesis argues that instead good or apt metaphors are understood through a categorization process, whether or not they are familiar. Only poor metaphors ever invoke a literal comparison. In Experiment 1, with aptness equated, we found that high familiarity speeded comprehension time over low-familiarity metaphors. In Experiment 2a, providing a literal prime failed to facilitate interpretation of low-familiarity metaphors, contrary to the career of metaphor hypothesis. In Experiment 2b, with familiarity equated, high- and low-aptness metaphors did not differ, contrary to the categorization hypothesis. [ABSTRACT FROM AUTHOR]

Planning a sentence with concrete concepts whose referents can be mentally imaged has been shown in past work to require the limited resources of visual working memory. By contrast, grammatically encoding such concepts as lexical items in a syntactic structure requires verbal working memory. We report an experiment designed to demonstrate a double dissociation of these two stores of working memory by manipulating the difficulty of (1) planning by comparing related concepts to unrelated concepts and (2) grammatical encoding of an English sentence in active voice versus the more complex structure of the passive voice. College students (N = 46) composed sentences that were to include two noun prompts (related versus unrelated) while concurrently performing either a visual or a verbal distracting task. Instructions to produce either active or passive sentences were manipulated between groups. The results surprisingly indicated that the supposedly easier planning with related concepts made a large demand on verbal working memory, rather than unrelated concepts demanding more visual working memory. Thie temporal dynamics of the sentence production process appear to best account for the unexpected findings. [ABSTRACT FROM AUTHOR]

While psychoanalytic and behavioral theorists have provided us with a variety of contradictory theories and problem-ridden empirical research related to consciousness, cognitive theorists have focused on the structural and procedural aspects of cognition and have tended to ignore questions related to how consciousness and the brain interact. In ''A Cognitive Theory of Consciousness'' (1988), Bernard J. Baars attempts to explain consciousness by proposing a theoretical framework in which consciousness involves a central information exchange area which he calls the global workspace. To be a part of conscious awareness, a thought or image must gain access to this area. Then, the central information exchange broadcasts messages to the entire mind-body system. Message broadcasting is achieved by 'specialized processors.' Each processor is thought of as a special skill which is highly practiced, automatic and unconscious. Baars cites evidence related to research on the development of automaticity with practice, and on research related to errors in perception, memory, language and knowledge. His conclusion is that while unconscious specialized processors mediate many cognitive abilities, they fail when faced with new, harmful or ambiguous situations. At such times, it is thought that the global workspace allows many processors to cooperate. These cooperative dynamics are described as being ruled by competition versus cooperation (inhibition versus neural excitation). Many phenomena that are well known in the areas of sensation, perception, learning, abstraction, language, thinking and problem solving are interpreted in terms of the global workspace model. Although the reader is not offered any alternative explanations for such phenomena, Baars' theory offers a novel and challenging contribution to cognitive theory.

A model of how working memory, as conceived by Baddeley (1986), supports the planning of ideas, translating ideas into Written sentences, and reviewing the ideas and text already produced was proposed by Kellogg (1996). A progress report based on research from The past 17 years shows strong support for the core assumption that planning translating, and reviewing are all dependent on the central executive. Similarly, the translation of ideas mio a sentence does in faci require also verbal working memory, but the claim that editing makes no demands on the phonological loop is tenuous. As predicted by the model, planning also engages the visuo-spatial sketchpad. However, it turns out to do so only in planning with concrete concepts that elicit mental imagery. Abstract concepts do not require visuo-spatial resources, a point not anticipated by the original model. Moreover, it is unclear the extent to which planning involves spatial as opposed to visual working memory. Contrary to Baddeley's original model, these are now known to be independent stores of working memory; the specific role of the spatial store in writing is uncertain based on the existing literature. The implications of this body of research for the instruction of writing are considered in the final section of the paper. [ABSTRACT FROM AUTHOR]

Note taking is a complex activity that requires comprehension and selection of information and written production processes. Here we review the functions, abbreviation procedures, strategies, and working memory constraints of note taking with the aim of improving theoretical and practical understanding of the activity. The time urgency of selecting key points and recording them while comprehending new information at the same time places significant demands on the central executive and other components of working memory. Dual- and triple-task procedures allow the measurement of the momentary cognitive effort or executive attention allocated to note taking. Comparative data show that note taking demands more effort than reading or learning. However, it requires less effort than the creative written composition of an original text.

Preparing a written outline during prewriting and composing a rough rather than a polished first draft are cognitive strategies that may lessen a writer's work load. The present laboratory and field research examined whether these strategies enhance writing performance. In an experiment, I manipulated the use of these strategies by college students in a letter writing task. The students' writing process, efficiency, and quality were examined. The results showed that preparing a written outline, compared with not doing so, increased the time spent translating ideas into text, improved the quality of letters, and failed to enhance overall efficiency. The use of rough versus polished drafts affected when the students reviewed their work, as expected, but had no influence on quality or efficiency. A survey of science and engineering faculty revealed that the frequency of using written outlines correlated positively with writing productivity, whereas use of polished drafts was uncorrelated with productivity.
