Articulatory coding and phonological judgements on written words and pictures: The role of the phonological output buffer

Abstract

The ability of Italian subjects to make phonological judgements was investigated in three experiments. The judgements comprised initial sound similarity and stress assignment on pain of both written words and pictures. Stress assignment on both words and pictures as well as initial sound similarity on pictures required the activation of phonological lexical representations, but this was not necessarily the case for initial sound similarity judgements on word pairs. The first study assessed the effects of concurrent articulatory suppression on the judgements. Experiment 2 used a concomitant task (chewing), which shares with suppression the use of articulatory components but does not involve speech programming and production. The third experiment investigated the effects of unattended speech on the phonological judgements. The results of these three experiments showed that articulatory suppression had a significant disrupting effect on accuracy in all four conditions, while neither articulatory non-speech (chewing) or unattended auditory speech had any effect on the subjects' performance. The results suggest that these phonological judgements involve the operation of an articulatory speech output component, which is not implemented peripherally and does not require the involvement of a non-articulatory input system.     

Chapter 9: A Christian Education for the Spiritual Growth of Senior Adults

SUMMARY

Spiritual maturity among older adults is not automatic. The achievement of this most significant and worthy goal is, in part, an individual's choice. However, it is assisted by the deliberate efforts of Christian education, as a church seeks to meet the needs of seniors by appealing to their life concerns. How this is done may vary, but the needs and interests of senior adults dictate that it must be done. This article provides an overview of older adults' needs as they relate to spiritual development, and then offers some general suggestions a church might consider for guiding them toward spiritual maturity.     

Dynamic binding of identity and location information: a serial model of multiple identity tracking

Tracking of multiple moving objects is commonly assumed to be carried out by a fixed-capacity parallel mechanism. The present study proposes a serial model (MOMIT) to explain performance accuracy in the maintenance of multiple moving objects with distinct identities. A serial refresh mechanism is postulated, which makes recourse to continuous attention switching, a capacity-limited episodic buffer for identity-location bindings, indexed location information stored in the visuospatial short-term memory, and an active role of long-term memory. As identity-location bindings are refreshed serially, a location error is inherent for all other targets except the focally attended one. The magnitude of this location error is a key factor in predicting tracking accuracy. MOMIT’s predictions were supported by the data of five experiments: performance accuracy decreased as a function of target set-size, speed, and familiarity. A mathematical version of MOMIT fitted nicely to the observed data with plausible parameter estimates for the binding capacity and refresh time.     

语文学习困难儿童的短时记忆、工作记忆和加工速度

短时记忆、工作记忆和加工速度反映了不同的认知加工.采用多因素混合实验设计,在严格控制条件下,比较了语文学习困难和控制组儿童的工作记忆、短时记忆和加工速度的差异.结果发现,与控制组相比,语文学习困难儿童在工作记忆、短时记忆和加工速度方面均存在明显的不足,但短时记忆和加工速度不能解释不同能力组之间的差异,语文学习困难儿童的缺陷在于工作记忆能力的下降.工作记忆的缺陷在于言语工作记忆的不足,与视空间工作记忆能力无关,语文学习困难与特定的工作记忆(言语工作记忆)能力的不足有关.工作记忆缺陷的原因在于存储能力的不足,而不是加工效率的缺陷造成的.     

The Gift Economy of Direct Transnational Civic Action: How Reciprocity and Inequality Are Managed in Religious “Partnerships”

How does religion help facilitate civic action in transnational contexts characterized by material inequality and spatial separation? Short‐term mission (STM) travel, a popular activity among U.S. religious groups, exemplifies a recently emerged form of transnational civic action characterized by face‐to‐face, decentralized, pragmatic activity. Our research analyzes how participants in STM‐based relationships manage inequality while pursuing an ideal of partnership across distance. We match data from a mixed methods study of Arizona congregations that produce STM travel with interview data from foreign religious organizations that host STM travelers in El Salvador. We engage gift exchange theory (GET) to show how a discursive repertoire combines with organized gift exchange practices to manage inequality and produce partnership in STM‐based relationships. Our data provide evidence of a unique cultural process, the spiritualization of reception, which emerges during gift reciprocation. This process converts unequal material gifts from foreign hosts into spiritual understanding among STM travelers, stabilizing status indebtedness that could threaten a partnership. This research increases knowledge of STM travel, shows how gift exchange structures can facilitate transnational religious partnerships, and suggests ways to use GET to understand transnational civic action in general.

Components of Short-Term Memory and Their Relation to Language Processing

Abstract— Verbal working memory consists of separable capacities for the retention of phonological and semantic information. Within the phonological domain, there are independent capacities for retaining input-phonological codes and output-phonological codes. The input-phonological capacity does not appear to be critical for language comprehension but is involved in verbatim repetition and long-term learning of new words. The semantic capacity is critical for both comprehension and production and for the learning of new semantic information. Different neural structures appear to underlie these capacities, with a left-parietal region involved in input-phonological retention and a left-frontal region involved in semantic retention.

Attentional modulation of perceptual comparison for feature binding

We investigated the neural correlates of attentional modulation in the perceptual comparison process for detecting feature-binding changes in an event-related functional magnetic resonance imaging (fMRI) experiment. Participants performed a variant of a cued change detection task. They viewed a memory array, a spatial retro-cue, and later a probe array. Their task was to judge whether the cued item had changed between the two arrays. Change type was manipulated to be a color-location binding or a color feature change. The retro-cue onset time in the retention interval was manipulated to be early or late. As a consequence of strong inter-item competition, we found strong prefrontal activation for late cues when contrasting the binding-change with the color-change condition. In contrast, we observed a comparable behavioral and neural effect between the two types of change detection when retro-cue was presented early. More importantly, we demonstrated a significant inter-regional correlation between the prefrontal and parietal regions in both binding- and color-change conditions for late cues. In addition, extensive prefrontal-parietal-visual functional connectivity was showed for detecting binding changes in the late-cueing condition. These results support the critical role in prefrontal-parietal-visual functional coupling for resolving strong inter-item competition during the comparison process in the binding-change condition. We provide direct evidence that attention modulates neural activity associated with perceptual comparison, biasing competition in favour of the task-relevant information in order to detect binding changes.     

Conduction aphasia, sensory-motor integration, and phonological short-term memory - an aggregate analysis of lesion and fMRI data

Conduction aphasia is a language disorder characterized by frequent speech errors, impaired verbatim repetition, a deficit in phonological short-term memory, and naming difficulties in the presence of otherwise fluent and grammatical speech output. While traditional models of conduction aphasia have typically implicated white matter pathways, recent advances in lesions reconstruction methodology applied to groups of patients have implicated left temporoparietal zones. Parallel work using functional magnetic resonance imaging (fMRI) has pinpointed a region in the posterior most portion of the left planum temporale, area Spt, which is critical for phonological working memory. Here we show that the region of maximal lesion overlap in a sample of 14 patients with conduction aphasia perfectly circumscribes area Spt, as defined in an aggregate fMRI analysis of 105 subjects performing a phonological working memory task. We provide a review of the evidence supporting the idea that Spt is an interface site for the integration of sensory and vocal tract-related motor representations of complex sound sequences, such as speech and music and show how the symptoms of conduction aphasia can be explained by damage to this system.
