Tracking independence and merging of prosodic and phonemic processing across infancy

Recent evidence suggests division of labor in phonological analysis underlying speech recognition. Adults and children appear to decompose the speech stream into phoneme‐relevant information and into syllable stress. Here we investigate whether both speech processing streams develop from a common path in infancy, or whether there are two separate streams from early on. We presented stressed and unstressed syllables (spoken primes) followed by initially stressed early learned disyllabic German words (spoken targets). Stress overlap and phoneme overlap between the primes and the initial syllable of the targets varied orthogonally. We tested infants 3, 6 and 9 months after birth. Event‐related potentials (ERPs) revealed stress priming without phoneme priming in the 3‐month‐olds; phoneme priming without stress priming in the 6‐month‐olds; and phoneme priming, stress priming as well as an interaction of both in 9‐month‐olds. In general the present findings reveal that infants start with separate processing streams related to syllable stress and to phoneme‐relevant information; and that they need to learn to merge both aspects of speech processing. In particular the present results suggest (i) that phoneme‐free prosodic processing dominates in early infancy; (ii) that prosody‐free phoneme processing dominates in middle infancy; and (iii) that both types of processing are operating in parallel and can be merged in late infancy.     

Comparing What to What,on What Scale? The Impact of Item Comparisons and Reference Points in Communicating Risk and Uncertainty

The mandated public availability of individual hospital's audit data for children's heart surgery in the UK creates a challenging scenario for communicating these complex and sensitive data to diverse audiences. On the basis of this scenario, we conducted three experiments with the aim of understanding how best to help lay people understand these data and the practical goal of improving the public presentation of these data. The experiments compared different outcome measures for displaying the survival rate (percentage scale versus the ratio of the predicted/observed rates) and presentation formats (individual hospital versus all hospitals shown) for outcomes data presented relative to prediction intervals generated by a risk model that adjusts for case mix. Our data highlight how easily inappropriate comparisons can influence evaluations of complex data: for instance, both a survival ratio of 1 and the presence of other hospitals seemingly provided reference points that resulted in inappropriately harsh evaluations of some hospitals. By drawing on evaluability theory, we demonstrate how to enhance people's understanding of these complex data while also discouraging inappropriate comparisons, which has implications for communicating risk and uncertainty and for choice architecture design in a range of contexts.

Knowing when to move on: cognitive and perceptual decisions in time

We investigated people's ability to decide how much time to spend on the task at hand. To make such decisions well, one must take into account, among other things, the cost of failing and how one's task performance changes as a function of time. We first investigated timing decisions when the underlying task was perceptual. Decisions were highly efficient and suggested that people can make good use of perceptual knowledge and abstract reward information. Previous studies have found that perceptual decisions are generally optimal, but that cognitive decisions are generally suboptimal--a perception-cognition gap. Does a similar gap exist for timing decisions? We compared timing decisions for a perceptual task with timing decisions for more cognitive tasks. Performance was highly similar across the tasks, which suggests that knowledge can be acquired, and used to make timing decisions, in an equally efficient way regardless of whether that knowledge is derived through perceptual or cognitive experience.     

Out of Sight Is Not Out of Mind: Developmental Changes in Infants' Understanding of Visual Perception During the Second Year

Three experiments investigated 14-, 18-, and 24- month-old infants' understanding of visual perception. Infants viewed films in which a protagonist was either able to view the location of a hidden object (Visual Access condition) or was blindfolded when the object location was revealed (No Visual Access condition). When requested to find the object, the protagonist pointed either at the correct location or at the incorrect location. Across experiments, 18-month-olds looked longer at the unexpected action (e.g., person pointing at the incorrect location in the Visual Access condition). By 24 month of age, infants could infer the correct search behavior from gaze alone. These findings suggest that by the middle of the second year of life, infants understand the psychological relation between an observer and an object, even if the object is no longer visible.     

Longitudinal Changes in Memory Performance and Processing Speed in Old Age abstract Keywords

The speed theory of cognitive aging posits that an age-related slowing of processing speed leads to impairments in higher order cognitive functions, such as memory. However, only few studies have examined the relationship between longitudinal changes in processing speed and longitudinal changes in memory performance. In the present study, data of 474 older adults (T1: 59–65 years) from the Interdisciplinary Longitudinal Study on Adult Development (ILSE) were used to investigate whether changes in speed and in memory were associated over a 4-year period. Performance changes in both constructs were analyzed using latent change factor models. Results show that latent changes in processing speed and latent changes in memory performance correlated with 0.61. This association is considerably lower than what would have been expected from cross-sectional data. Our longitudinal results suggest that although speed changes explain a substantial proportion of variance in memory changes, additional explanatory factors must be taken into consideration.     

Similarity chains in the transformational paradigm

Rips’ (1989) results with the transformational paradigm have often been cited as supporting accounts of categorisation not based on similarity, such as involving necessary or sufficient features (or a belief in such features), which guarantee a categorisation outcome once their presence has been established. We discuss a similarity account of the transformational paradigm based on similarity chains, which predicts that when the transformation is more gradual the identity of the transformed object is less likely to change. Conversely, we suggest that an essentialist approach to categorisation predicts that essences are more likely to change in gradual transformations, across generations, as is the case with evolutionary change of species. In two experiments we examined the scope of the similarity versus the essentialist account in the transformational paradigm. With space aliens, the similarity account was superior to the essentialist one, but the converse was true with earth creatures. We suggest that an essentialist mode of categorisation is more likely than a similarity one for stimuli that are in better correspondence with our naïve understanding of the world.     

Musiktherapie in der deutschen Psychosomatik

The authors report about the clinical implementation of music therapy in psychosomatic hospitals in FRG based on a survey among practising music therapists: attending especially to the qualification of music therapists, their integration and the problem of indication. The coverage of music therapy in the standard textbooks on psychosomatic medicine is discussed.Finally the state of research on music therapy in psychosomatic hospitals is reviewed.     

Emotion regulation through listening to music in everyday situations

Music is a stimulus capable of triggering an array of basic and complex emotions. We investigated whether and how individuals employ music to induce specific emotional states in everyday situations for the purpose of emotion regulation. Furthermore, we wanted to examine whether specific emotion-regulation styles influence music selection in specific situations. Participants indicated how likely it would be that they would want to listen to various pieces of music (which are known to elicit specific emotions) in various emotional situations. Data analyses by means of non-metric multidimensional scaling revealed a clear preference for pieces of music that were emotionally congruent with an emotional situation. In addition, we found that specific emotion-regulation styles might influence the selection of pieces of music characterised by specific emotions. Our findings demonstrate emotion-congruent music selection and highlight the important role of specific emotion-regulation styles in the selection of music in everyday situations.     

From Nehemia Americanus to Indianized Jews

This article explores the entangled history of transnational race discourses in the colonialism of early Puritan settlers in New England. Retracing the complexity of discursive intersections between proto-racist, anti-Judaic and pro-Judaic rhetoric within Puritan minority narratives, it asks how these discourses changed when theological concepts around Self and Other, Old and New Israel, were translated from Europe to the North American colonies. The settlers’ millenarian theology forged an eschatological link between the American wilderness and the religious and political heterotopia of a New Jerusalem; Cotton Mather's Magnalia Christi Americana (1702), for example, idealized the figure of the colonial founding father as an American Nehemiah or Moses. In the settlers’ vision, the Puritans stood in competition with Old Israel, aiming to assume its role and basing their apocalyptic interpretations of the flight from Europe on its exodus. At the same time, they transferred images of Europe's “internal colonized”—the Jews—to the indigenous population. In the frontier zone of colonial contact, the Puritans combined older anti-Judaic with their own millenarian pro-Judaic ideas in new ways, a process that converged in the notion that the “Indians” were descendants of the 10 lost tribes of Israel and their religion was similar to that of the biblical Israelites.
