Programming and reprogramming sequence timing following high and low contextual interference practice.
Individuals practiced two unique discrete sequence production tasks that differed in their relative time profile in either a blocked or random practice schedule. Each participant was subsequently administered a "precuing" protocol to examine the cost of initially compiling or modifying the plan for an upcoming movement's relative timing. The findings indicated that, in general, random practice facilitated the programming of the required movement timing, and this was accomplished while exhibiting greater accuracy in movement production. Participants exposed to random practice exhibited the greatest motor programming benefit, when a modification to an already prepared movement timing profile was required. When movement timing was only partially constructed prior to the imperative signal, the individuals who were trained in blocked and random practice formats accrued a similar cost to complete the programming process. These data provide additional support for the recent claim of Immink & Wright (2001) that at least some of the benefit from experience in a random as opposed to blocked training context can be localized to superior development and implementation of the motor programming process before executing the movement.

Apraxia of speech: an overview.
Apraxia of speech (AOS) is a motor speech disorder that can occur in the absence of aphasia or dysarthria. AOS has been the subject of some controversy since the disorder was first named and described by Darley and his Mayo Clinic colleagues in the 1960s. A recent revival of interest in AOS is due in part to the fact that it is often the first symptom of neurodegenerative diseases, such as primary progressive aphasia and corticobasal degeneration. This article will provide a brief review of terminology associated with AOS, its clinical hallmarks and neuroanatomical correlates. Current models of motor programming will also be addressed as they relate to AOS and finally, typical treatment strategies used in rehabilitating the articulation and prosody deficits associated with AOS will be summarized.

Observations from Ground Zero at the World Trade Center in New York City, Part II: Theoretical and clinical considerations.
Part I of this series discussed our observations of Ground Zero of the World Trade Center (WTC) immediately after the attack on September 11, 2001, as well as the stress-response of police officers on site. This paper offers a variety of clinical techniques for emergency mental health practitioners and first responders for use with victims of critical incidents. The suggested interventions are based on the theory and clinical practice of Emergency Medical Hypnosis, Neuro-Linguistic Programming, and Ericksonian Psychotherapy. Specific examples of how they were applied with police personnel following the World Trade Center attack are provided along with specific clinical guidelines. These interventions are designed to augment and enhance standard CISM, mental health, and medical practice in the field.

A biologically inspired neural network for dynamic programming.
An artificial neural network with a two-layer feedback topology and generalized recurrent neurons, for solving nonlinear discrete dynamic optimization problems, is developed. A direct method to assign the weights of neural networks is presented. The method is based on Bellmann's Optimality Principle and on the interchange of information which occurs during the synaptic chemical processing among neurons. The neural network based algorithm is an advantageous approach for dynamic programming due to the inherent parallelism of the neural networks; further it reduces the severity of computational problems that can occur in methods like conventional methods. Some illustrative application examples are presented to show how this approach works out including the shortest path and fuzzy decision making problems.

Intuition in nursing relationships: the result of 'skills' or 'qualities'?
Maintaining the scientific orientation of health and nursing care systems has resulted in a lack of focus on nurses' intuitive knowledge base. Consequently, confusion exists as to whether intuition in nursing is the result of acquired skills, or is dependent upon the inherent qualities of the individual. In deconstructing the apparently intuitive process of building rapport, neuro-linguistic programming (NLP) can offer insight, suggesting that rapport building depends on learnt skills that have moved into unconscious competence. The examination of nurses' intuitive knowledge, in order to identify underlying skills, needs to be just as rigorous as the acquisition of scientific knowledge. Examining intuitive knowledge can be achieved within a framework of reflective practice to counter the inherent dangers of an increasingly scientific approach operating within a caring profession.

Our personal space.
Neuro Linguistic Programming (NLP) as a model of human behaviour is presented. Its basic tenets and the factors that give rise to the physiological and emotional response to an external event are described. A number of psychotherapeutic interventions are also described, along with the influence of NLP on sporting and academic success. Finally, an exploration of these ideas for the purpose of contributing to personal well-being is given.

Maternal programming of defensive responses through sustained effects on gene expression.
There are profound maternal effects on individual differences in defensive responses and reproductive strategies in species ranging literally from plants to insects to birds. Maternal effects commonly reflect the quality of the environment and are most likely mediated by the quality of the maternal provision (egg, propagule, etc.), which in turn determines growth rates and adult phenotype. In this paper we review data from the rat that suggest comparable forms of maternal effects on defensive responses stress, which are mediated by the effects of variations in maternal behavior on gene expression. Under conditions of environmental adversity maternal effects enhance the capacity for defensive responses in the offspring. In mammals, these effects appear to 'program' emotional, cognitive and endocrine systems towards increased sensitivity to adversity. In environments with an increased level of adversity, such effects can be considered adaptive, enhancing the probability of offspring survival to sexual maturity; the cost is that of an increased risk for multiple forms of pathology in later life.

Lateralization of cognitive processes in the brain.
The lateralization of cognitive processes in the brain is discussed. The traditional view of a language-visuo/spatial dichotomy of function between the hemispheres has been replaced by more subtle distinctions. The use of magnetic resonance imaging (MRI) to study brain morphology has resulted in a renewed focus on the relationship between structural and functional asymmetry. Focus has been on the role played by the planum temporale area in the posterior part of the superior temporal gyrus for language asymmetry, and the possible significance of the larger left planum. The dichotic listening technique is used to illustrate the difference between bottom-up, or stimulus-driven laterality versus top-down, or instruction-driven laterality. It is suggested that the hemispheric dominance observed at any time is the sum result of the dynamic interaction between bottom-up and top-down processing tendencies. Stimulus-driven laterality dominance is always monitored and modulated through top-down cognitive processes, like shifting of attention and changes in arousal. A model of top-down modulation of bottom-up laterality is presented with special reference to the understanding of psychiatric disorders.

The cognitive neuroscience of signed language.
The present article is an assessment of the current state of knowledge in the field of cognitive neuroscience of signed language. Reviewed lesion data show that the left hemisphere is dominant for perception and production of signed language in aphasics, in a fashion similar to spoken language aphasia. Several neuropsychological dissociations support this claim: Non-linguistic visuospatial functions can be dissociated from spatial functions and general motor deficits can be dissociated from execution of signs. Reviewed imaging data corroborate the lesion data in that the importance of the left hemisphere is re-confirmed. The data also establish the role of the right hemisphere in signed language processing. Alternative hypotheses regarding what aspects of signed language processing are handled by the right hemisphere are currently tested. The second section of the paper starts by addressing the role that early acquisition of signed and spoken language play for the neurofunctional activation patterns in the brain. Compensatory cognitive and communicative enhancements have also been documented as a function of early sign language use, suggesting an interesting interaction between language and cognition. Recent behavioural data on sign processing in working memory--a cognitive system important for language perception and production suggest e.g. phonological loop effects analogous to those obtained for speech processing. Neuroimaging studies will have to address this potential communality.

Is there a natural order for expressing semantic relations?
All languages rely to some extent on word order to signal relational information. Why? We address this question by exploring communicative and cognitive factors that could lead to a reliance on word order. In Study 1, adults were asked to describe scenes to another using their hands and not their mouths. The question was whether this home-made "language" would contain gesture sentences with consistent order. In addition, we asked whether reliance on order would be influenced by three communicative factors (whether the communication partner is permitted to give feedback; whether the information to be communicated is present in the context that recipient and gesturer share; whether the gesturer assumes the role of gesture receiver as well as gesture producer). We found that, not only was consistent ordering of semantic elements robust across the range of communication situations, but the same non-English order appeared in all contexts. Study 2 explored whether this non-English order is found only when a person attempts to share information with another. Adults were asked to reconstruct scenes in a non-communicative context using pictures drawn on transparencies. The adults picked up the pictures for their reconstructions in a consistent order, and that order was the same non-English order found in Study 1. Finding consistent ordering patterns in a non-communicative context suggests that word order is not driven solely by the demands of communicating information to another, but may reflect a more general property of human thought.

Challenging the widespread assumption that connectionism and distributed representations go hand-in-hand.
One of the central claims associated with the parallel distributed processing approach popularized by D.E. Rumelhart, J.L. McClelland and the PDP Research Group is that knowledge is coded in a distributed fashion. Localist representations within this perspective are widely rejected. It is important to note, however, that connectionist networks can learn localist representations and many connectionist models depend on localist coding for their functioning. Accordingly, a commitment to distributed representations should be considered a specific theoretical claim regarding the structure of knowledge rather than a core principle, as often assumed. In this paper, it is argued that there are fundamental computational and empirical challenges that have not yet been addressed by distributed connectionist theories that are readily accommodated within localist approaches. This is highlighted in the context of modeling word and nonword naming, the domain in which some of the strongest claims have been made. It is shown that current PDP models provide a poor account of naming monosyllable items, and that distributed representations make it difficult for these models to scale up to more complex language phenomena. At the same time, models that learn localist representations are shown to hold promise in supporting many of the core reading and language functions on which PDP models fail. It is concluded that the common rejection of localist coding schemes within connectionist architectures is premature.

The recognition of gender-marked nouns and verbs in Polish-speaking aphasic patients.
In the present study, we investigated the on-line recognition of gender-marked lexical items by three aphasic patients and eighteen matched control participants, all native speakers of Polish. Polish is unique in that it allows investigating grammatical gender across the major categories of nouns and verbs. Patients and their controls were tested using a simple visual lexical decision paradigm in which gender, number and grammatical category were manipulated. Results show that, while response latencies were markedly slower for aphasic patients, gender did not yield differential results in either grammatical category, for both patients and control participants. Plural forms, on the other hand, showed significantly slower response latencies than singular forms in both brain-damaged and unimpaired participants, but only for nouns. We interpret these findings in terms of the inherent vs. contextual, i.e. underspecified, nature of gender and number in the two grammatical categories. This study suggests that while gender can be impaired in off-line performance in aphasia, on-line recognition patterns parallel the performance of non-brain-damaged individuals, confirming the preservation of access procedures in automatic word recognition.

From monkey-like action recognition to human language: an evolutionary framework for neurolinguistics.
The article analyzes the neural and functional grounding of language skills as well as their emergence in hominid evolution, hypothesizing stages leading from abilities known to exist in monkeys and apes and presumed to exist in our hominid ancestors right through to modern spoken and signed languages. The starting point is the observation that both premotor area F5 in monkeys and Broca's area in humans contain a "mirror system" active for both execution and observation of manual actions, and that F5 and Broca's area are homologous brain regions. This grounded the mirror system hypothesis of Rizzolatti and Arbib (1998) which offers the mirror system for grasping as a key neural "missing link" between the abilities of our nonhuman ancestors of 20 million years ago and modern human language, with manual gestures rather than a system for vocal communication providing the initial seed for this evolutionary process. The present article, however, goes "beyond the mirror" to offer hypotheses on evolutionary changes within and outside the mirror systems which may have occurred to equip Homo sapiens with a language-ready brain. Crucial to the early stages of this progression is the mirror system for grasping and its extension to permit imitation. Imitation is seen as evolving via a so-called simple system such as that found in chimpanzees (which allows imitation of complex "object-oriented" sequences but only as the result of extensive practice) to a so-called complex system found in humans (which allows rapid imitation even of complex sequences, under appropriate conditions) which supports pantomime. This is hypothesized to have provided the substrate for the development of protosign, a combinatorially open repertoire of manual gestures, which then provides the scaffolding for the emergence of protospeech (which thus owes little to nonhuman vocalizations), with protosign and protospeech then developing in an expanding spiral. It is argued that these stages involve biological evolution of both brain and body. By contrast, it is argued that the progression from protosign and protospeech to languages with full-blown syntax and compositional semantics was a historical phenomenon in the development of Homo sapiens, involving few if any further biological changes.

Thematic relations in adults' concepts.
Concepts can be organized by their members' similarities, forming a kind (e.g., animal), or by their external relations within scenes or events (e.g., cake and candles). This latter type of relation, known as the thematic relation, is frequently found to be the basis of children's but not adults' classification. However, 10 experiments found that when thematic relations are meaningful and salient, they have significant influence on adults' category construction (sorting), inductive reasoning, and verification of category membership. The authors conclude that concepts function closely with knowledge of scenes and events and that this knowledge has a role in adults' conceptual representations.

Models of phonology in the education of speech-language pathologists.
We discuss developments in theoretical phonology and, in particular, at the divide between theories aiming to be adequate accounts of the data, as opposed to those claiming psycholinguistic validity. It would seem that the latter might have greater utility for thye speech-language pathologist. However, we need to know the dominant models of clinical phonology, in both clinical education and practise, before we can promote other theoretical approaches. This article describes preliminary results from a questionnaire designed to discover what models of phonology are taught in institutions training speech-language pathologists in the United States. Results support anecdotal evidence that only a limited number of approaches (phonemic, distinctive features, and processes) are taught in many instances. They also demonstrate that some correspondents were unable to distinguish aspects of theoretical phonology from similar sounding (but radically different) models of intervention. This ties in with the results showing that some instructors of phonology courses have little or no background in the subject.
