Language and the young stutterer: A new look at old theories and findings

The major theories and research approaches as to the etiology and development of stuttering are reviewed from a historical perspective. Findings are drawn from different sources indicating that language deficits are an initial contributing factor and a continuing component of this disorder. Those subsets of children which constitute high-risk groups are identified. It is suggested that researchers begin investigating the underlying organic bases of stuttering and its relationship to stages of language development. Finally, clinicians are encouraged to employ a therapy program that is concerned with all areas of language, rather than emphasizing treating only the symptoms of stuttering behavior.     

The empirical status of empirically supported psychotherapies: assumptions, findings, and reporting in controlled clinical trials

This article provides a critical review of the assumptions and findings of studies used to establish psychotherapies as empirically supported. The attempt to identify empirically supported therapies (ESTs) imposes particular assumptions on the use of randomized controlled trial (RCT) methodology that appear to be valid for some disorders and treatments (notably exposure-based treatments of specific anxiety symptoms) but substantially violated for others. Meta-analytic studies support a more nuanced view of treatment efficacy than implied by a dichotomous judgment of supported versus unsupported. The authors recommend changes in reporting practices to maximize the clinical utility of RCTs, describe alternative methodologies that may be useful when the assumptions underlying EST methodology are violated, and suggest a shift from validating treatment packages to testing intervention strategies and theories of change that clinicians can integrate into empirically informed therapies.     

Autumn leaves and old photographs: The development of metaphor preferences

In order to determine the development of preferences for different types of metaphors, a metaphor preferences task was designed. Subjects at seven ages, from 6 through 20 years, received incomplete sentences followed by metaphorical and literal completions, and were asked to select their preferred completions. The pattern of preferences shifted with age. Metaphors based on grounds involving color or shape were preferred by the youngest subjects; metaphors based on movement or sound were preferred by subjects of intermediate age; and metaphors based on nonperceptual, conceptual grounds were preferred by the oldest subjects. At all ages the most frequently chosen metaphors were those based on a combination of two grounds (e.g., color and shape). Preference for literal completions declined with age, but there was an increase in literal selections in the 8th and 10th grades. This study demonstrates the systematic development of aesthetic preferences in the domain of figurative language.     

A unitary Neo-Piagetian/Neo-Eriksonian model of development: Fundamental assumptions and meta-issues

The article briefly reviews a stage model of change in human development that integrates a Neo-Piagetian model and a Neo-Eriksonian model into one unitary stage model across the lifespan (as presented in Young, 2011). The model suggests a generic model of stages in change. The article explores the fundamental assumptions underlying the model as well as considering meta-issues. The article adds to the book by describing the Neo-Eriksonian stages as reflections of a social “participatory” process. It adds to the change process in development by describing it as possibly reflecting “punctuated disequilibrium.” Finally, it adds a “multiple psychodynamics” model.     

Intelligence: new findings and theoretical developments

We review new findings and new theoretical developments in the field of intelligence. New findings include the following: (a) Heritability of IQ varies significantly by social class. (b) Almost no genetic polymorphisms have been discovered that are consistently associated with variation in IQ in the normal range. (c) Much has been learned about the biological underpinnings of intelligence. (d) "Crystallized" and "fluid" IQ are quite different aspects of intelligence at both the behavioral and biological levels. (e) The importance of the environment for IQ is established by the 12-point to 18-point increase in IQ when children are adopted from working-class to middle-class homes. (f) Even when improvements in IQ produced by the most effective early childhood interventions fail to persist, there can be very marked effects on academic achievement and life outcomes. (g) In most developed countries studied, gains on IQ tests have continued, and they are beginning in the developing world. (h) Sex differences in aspects of intelligence are due partly to identifiable biological factors and partly to socialization factors. (i) The IQ gap between Blacks and Whites has been reduced by 0.33 SD in recent years. We report theorizing concerning (a) the relationship between working memory and intelligence, (b) the apparent contradiction between strong heritability effects on IQ and strong secular effects on IQ, (c) whether a general intelligence factor could arise from initially largely independent cognitive skills, (d) the relation between self-regulation and cognitive skills, and (e) the effects of stress on intelligence.     

B-theory old and new: on ontological commitment

The most important argument against the B-theory of time is the paraphrase argument. The major defense against that argument is the “new” tenseless theory of time, which is built on what I will call the “indexical reply” to the paraphrase argument. The move from the “old” tenseless theory of time to the new is most centrally a change of viewpoint about the nature and determiners of ontological commitment. Ironically, though, the new tenseless theorists have generally not paid enough sustained, direct attention to that notion. I will defend a general criterion of ontological commitment and apply it to generate a version of the new tenseless theory of time. I will argue that many of the extant versions of the new tenseless theory of time (specifically, all those which seek to identify tenseless truth-conditions of tensed sentences as a way out of apparent ontological commitment to tensed features of reality) are unsatisfactory because their general criterion of ontological commitment is inadequate. Those versions of the new tenseless theory which are adequate (specifically, those which identify tenseless truthmakers for tensed sentences) actually entail the criterion of ontological commitment that I defend, despite appearances to the contrary.     

The old and thee, uh, new: disfluency and reference resolution

Most research on the rapid mental processes of on-line language processing has been limited to the study of idealized, fluent utterances. Yet speakers are often disfluent, for example, saying "thee, uh, candle" instead of "the candle." By monitoring listeners' eye movements to objects in a display, we demonstrated that the fluency of an article ("thee uh" vs. "the") affects how listeners interpret the following noun. With a fluent article, listeners were biased toward an object that had been mentioned previously, but with a disfluent article, they were biased toward an object that had not been mentioned. These biases were apparent as early as lexical information became available, showing that disfluency affects the basic processes of decoding linguistic input.     

Internal consistency of tests: Analyses old and new

A coefficient derived from communalities of test parts has been proposed as greatest lower bound to Guttman's immediate retest reliability. The communalities have at times been calculated from covariances between itemsets, which tends to underestimate appreciably. When items are experimentally independent, a consistent estimate of the greatest defensible internal-consistency coefficient is obtained by factoring item covariances. In samples of modest size, this analysis capitalizes on chance; an estimate subject to less upward bias is suggested. For estimating alternate-forms reliability, communality-based coefficients are less appropriate than stratified alpha.I thank Edward Haertel for comments and suggestions, and Andrew Comrey for data.     

The development of enemy images in Dutch children: Measurement and initial findings

While there is ample evidence that enemies and enemy images are prerequisites in preparedness for war, little information is available about children's understanding of enemies or the presence of enemy images. Based on a pilot study in which assessment instruments were developed and validated, the present study examined the understanding of enemies and the presence of enemy images in 221 Dutch children aged between 7 and 12 years. The instruments employed involved the request to draw an enemy and an individual interview. Contrary to the expectation that younger children's enemy images would consist primarily of fictitious, non-human figures, whereas older children's images would focus more on realistic others as enemies, the findings revealed an opposite developmental course: younger children perceived enemies more often as concrete others, while older children perceived enemies more often as non-human, fictitious others. In addition, an age-related increase in children's experienced threats that cannot be reduced to concrete external causes was observed. Taken together with a growing awareness that enemies are characterized primarily by internal personality characteristics, latent (undefined) enemy images may easily become concrete enemies when an external focus is provided.     

The introductory class in higher education: Some old problems and new considerations

The traditional text and lecture format has remained the norm in introductory college courses despite evidence, such as the personalized system of instruction, that other practices could improve what is learned and retained. The growth of distance learning provides new opportunities to implement effective teaching practices. Unfortunately, an adequate comparison of various teaching practices is not possible (even with regard to the teaching of behavior analysis). Few practices have been assessed with respect to course-end effects (final exam performance), and longer term effects remain almost wholly unexplored. Studies of the retention of academic materials, the practice required for mastery or fluency, and the relation between verbal repertoires and correspondent everyday behaviors suggest course outcomes more modest than those hoped for earlier. Suggestions for changing current practices have little credibility until the size of the gap between present and possible learning outcomes is much better known, and the personal, social, and economic consequences of bridging that gap (or not) are assessed.     

Neuropragmatism, old and new

Recent work in neurophilosophy has either made reference to the work of John Dewey or independently developed positions similar to it. I review these developments in order first to show that Dewey was indeed doing neurophilosophy well before the Churchlands and others, thereby preceding many other mid-twentieth century European philosophers’ views on cognition to whom many present day philosophers refer (e.g., Heidegger, Merleau-Ponty). I also show that Dewey’s work provides useful tools for evading or overcoming many issues in contemporary neurophilosophy and philosophy of mind. In this introductory review, I distinguish between three waves among neurophilosophers that revolve around the import of evolution and the degree of brain-centrism. Throughout, I emphasize and elaborate upon Dewey’s dynamic view of mind and consciousness. I conclude by introducing the consciousness-as-cooking metaphor as an alternative to both the consciousness-as-digestion and consciousness-as-dancing metaphors. Neurophilosophical pragmatism—or neuropragmatism—recognizes the import of evolutionary and cognitive neurobiology for developing a science of mind and consciousness. However, as the cooking metaphor illustrates, a science of mind and consciousness cannot rely on the brain alone—just as explaining cooking entails more than understanding the gut—and therefore must establish continuity with cultural activities and their respective fields of inquiry. Neuropragmatism advances a new and promising perspective on how to reconcile the scientific and manifest images of humanity as well as how to reconstruct the relationship between science and the humanities.     

Memorizing while walking: increase in dual-task costs from young adulthood to old age

The dual task of memorizing word lists while walking was predicted to become more difficult with age because balance and gait are in greater need of "attentional resources." Forty-seven young (ages 20-30 years), 45 middle-aged (40-50), and 48 old (60-70) adults were trained to criterion in a mnemonic technique and instructed to walk quickly and accurately on 2 narrow tracks of different path complexity. Then. participants encoded the word lists while sitting, standing, or walking on either track; likewise, speed and accuracy of walking performance were assessed with and without concurrent memory encoding. Dual-task costs increased with age in both domains; relative to young adults, the effect size of the overall increase was 0.98 standard deviation units for middle-aged and 1.47 standard deviation units for old adults. It is argued that sensory and motor aspects of behavior are increasingly in need of cognitive control with advancing age.     

Neural fetal tissue transplants: old and new issues

Abstract. Neural fetal tissue transplantation offers promise as a treatment for devasting neurologic conditions such as Parkinson's disease. Two types of issues arise from this procedure: those associated with the use of fetuses, and those associated with the use of neural tissue. The former issues have been examined in many forums; the latter have not. This paper reviews issues and arguments raised by the use of fetal tissue in general, but focuses on the implications of the use of neural tissue for basic concepts of personnood and personal identity.     

Early stage of walking: development of control in mediolateral and anteroposterior directions

The authors examined the changes in bipedal gait of toddlers in the anteroposterior (AP) and mediolateral (ML) directions, as a set, at the onset of independent gait and 1 month after onset. Two groups with distinctly different dynamic resources were studied: 8 toddlers with typical development (TD) and 8 toddlers with Down syndrome (DS). Three-dimensional kinematic data were collected, and gait parameters, such as walking speed, stride length, and stride frequency, as well as the ratio of exchange between potential energy and kinetic energy of the center of mass (COM), were calculated. Displacement of the COM in the AP and ML directions were also analyzed. For some gait variables, toddlers with DS seemed to show more mature values at walking onset than their peers with TD. Those group differences reversed and increased by Visit 2. When the authors considered the motion of the COM of the system, it became clear that the qualitative differences between those groups were characterized primarily by constraints in the ML direction. The authors propose that establishment of coupling between AP and ML oscillations is a key component for the emergence of independent bipedal walking for both populations.     

When everything new is well-forgotten old: Vygotsky/Luria insights in the development of executive functions

The concept of "extra-cortical organization of higher mental functions" proposed by Lev Vygotsky and expanded by Alexander Luria extends cultural-historical psychology regarding the interplay of natural and cultural factors in the development of the human mind. Using the example of self-regulation, the authors explore the evolution of this idea from its origins to recent findings on the neuropsychological trajectories of the development of executive functions. Empirical data derived from the Tools of the Mind project are used to discuss the idea of using classroom intervention to study the development of self-regulation in early childhood.
