The role of prosodic boundaries in the resolution of lexical embedding in speech comprehension

Participants' eye movements were monitored as they heard sentences and saw four pictured objects on a computer screen. Participants were instructed to click on the object mentioned in the sentence. There were more transitory fixations to pictures representing monosyllabic words (e.g. ham) when the first syllable of the target word (e.g. hamster) had been replaced by a recording of the monosyllabic word than when it came from a different recording of the target word. This demonstrates that a phonemically identical sequence can contain cues that modulate its lexical interpretation. This effect was governed by the duration of the sequence, rather than by its origin (i.e. which type of word it came from). The longer the sequence, the more monosyllabic-word interpretations it generated. We argue that cues to lexical-embedding disambiguation, such as segmental lengthening, result from the realization of a prosodic boundary that often but not always follows monosyllabic words, and that lexical candidates whose word boundaries are aligned with prosodic boundaries are favored in the word-recognition process.     

Cognitive change and enhanced coping: missing mediational links in cognitive behavior therapy with anxiety-disordered children

In this review, we examine the recent cognitive behavior therapy (CBT) outcome literature with anxiety-disordered children and, specifically, explore the status of cognitive change and increased coping ability as (1) specific treatment effects, and (2) possible mediators of the efficacy of CBT. In the past decade, the number of controlled CBT studies with clinically diagnosed anxiety-disordered children has increased substantially. CBT aims to restructure distorted or maladaptive cognitions and teach the anxious child to effectively use diverse coping strategies. Our review shows that in recent CBT research with anxiety-disordered children the use of domain-specific measures like cognitive and coping measures is, unfortunately, not common practice. Furthermore, only one study examined the issue of treatment mediation. Generally, recent CBT research has not been designed to test mediational issues and does not clarify whether cognitive change and enhanced coping—the presumed central components of CBT—are in fact responsible for its efficacy. Implications for the direction of future CBT research with anxiety-disordered children are discussed.     

Effects of prosodically modulated sub-phonetic variation on lexical competition

Eye movements were monitored as participants followed spoken instructions to manipulate one of four objects pictured on a computer screen. Target words occurred in utterance-medial (e.g., Put the cap next to the square) or utterance-final position (e.g., Now click on the cap). Displays consisted of the target picture (e.g., a cap), a monosyllabic competitor picture (e.g., a cat), a polysyllabic competitor picture (e.g., a captain) and a distractor (e.g., a beaker). The relative proportion of fixations to the two types of competitor pictures changed as a function of the position of the target word in the utterance, demonstrating that lexical competition is modulated by prosodically conditioned phonetic variation.     

Body–Mind Integrality: Remarks on the Nature and Origin of Universe and Life

This article summarizes scientific knowledge in the fields of quantum physics and medical science regarding the origin and the nature of the universe and life. The recent discoveries in the fields of biophysics, genetics, epigenetics, neuroscience, and psychosomatics describe the universe and life as highly coherent systems where information is a key factor. In this concept living systems are cognitive networks in a dynamic relationship with their environment. Health in this context is a dynamic balance in a subject in which the information flows functionally. Disease is identified as a pathology of information that can be classified in a new way, considering two different codes of meaning—the semiotic and the symbolic.     

Can Motivation Normalize Working Memory and Task Persistence in Children with Attention-Deficit/Hyperactivity Disorder? The Effects of Money and Computer-Gaming

Visual-spatial Working Memory (WM) is the most impaired executive function in children with Attention-Deficit/Hyperactivity Disorder (ADHD). Some suggest that deficits in executive functioning are caused by motivational deficits. However, there are no studies that investigate the effects of motivation on the visual-spatial WM of children with- and without ADHD. Studies examining this in executive functions other than WM, show inconsistent results. These inconsistencies may be related to differences in the reinforcement used. The effects of different reinforcers on WM performance were investigated in 30 children with ADHD and 31 non-ADHD controls. A visual-spatial WM task was administered in four reinforcement conditions: Feedback-only, 1 euro, 10 euros, and a computer-game version of the task. In the Feedback-only condition, children with ADHD performed worse on the WM measure than controls. Although incentives significantly improved the WM performance of children with ADHD, even the strongest incentives (10 euros and Gaming) were unable to normalize their performance. Feedback-only provided sufficient reinforcement for controls to reach optimal performance, while children with ADHD required extra reinforcement. Only children with ADHD showed a decrease in performance over time. Importantly, the strongest incentives (10 euros and Gaming) normalized persistence of performance in these children, whereas 1 euro had no such effect. Both executive and motivational deficits give rise to visual-spatial WM deficits in ADHD. Problems with task-persistence in ADHD result from motivational deficits. In ADHD-reinforcement studies and clinical practice (e.g., assessment), reinforcement intensity can be a confounding factor and should be taken into account. Gaming can be a cost-effective way to maximize performance in ADHD.     

Rediscovering Meaning

The present crisis of the Western countries involves not just the world of politics, finance, and the economy, but also the ecosystem balance, the world of the values on which the model of social organization and economic development is based. The crisis is therefore systemic, epoch-making, and overcoming it will require radical changes, above all in the way we think, in our scale of values, and therefore our culture. On the other hand, for decades the world—in particular the West—has been experiencing a cultural sea-change that is challenging many of the pillars of society that have stood for centuries. The young people of today and their use of technological social networks to develop non-profit initiatives for social change may create a more positive future while maintaining our human values.     

Simulating Ordinal Data

The increasing use of ordinal variables in different fields has led to the introduction of new statistical methods for their analysis. The performance of these methods needs to be investigated under a number of experimental conditions. Procedures to simulate from ordinal variables are then required. In this article, we deal with simulation from multivariate ordinal random variables. We propose a new procedure for generating samples from ordinal random variables with a prespecified correlation matrix and marginal distributions. Its features are examined and compared with those of its main competitors. A software implementation in R is also provided along with examples of its application.     

A Different Approach to Dependence Analysis

This article focuses on a statistical tool for dependence analysis in scientific research. Starting from a recent index of concordance for a multiple linear regression model, a coefficient suitable in catching any monotonic dependence relationship between a dependent variable and an independent variable is derived and discussed. Given its interpretation in terms of monotonic dependence, it is called monotonic dependence coefficient (MDC). It is appropriate to all contexts where the dependent variable is quantitative (continuous or discrete) and the independent variable is at least of ordinal nature; tied data are also allowed. MDC’s adequacy is validated through Monte Carlo simulations led by taking into account different scenarios of dependence. Finally, an application to real data is provided to stress MDC’s capability of detecting dependence relationships between two variables, even if some pieces of information about original data are lost.     

The effects of ongoing activity on time estimation in prospective remembering

Two experiments examined whether time‐based prospective memory performance is influenced by the continuous or discontinuous nature of an ongoing activity. The first experiment demonstrated that prospective memory performance was not influenced by the engagement in continuous or discontinuous ongoing activity. The second experiment demonstrated that a discontinuous ongoing activity negatively affected prospective memory performance when participants had to execute two time‐based tasks for which the retention intervals partially overlapped. The results suggest that when individuals are engaged in multiple time‐based tasks, a general timing disruption occurs, with a proactive interference effect resulting in costs that are detrimental to prospective timing.
