Le disfluenze e la percezione degli ascoltatori. Valutazione di tre interpretazioni consecutive.

This study aims at exploring listeners’ perception of disfluencies, i.e. ungrammatical pauses, filled pauses, repairs, false starts and repetitions, which can irritate listeners and impede comprehension. As professional communicators, conference interpreters should be competent public speakers. This means that their speech should be easily understood by listeners and not contain elements that may be considered irritating. The aim of this study was to understand to what extent listeners notice disfluencies and consider them irritating, and to examine whether there are differences between interpreters and non-interpreters and between different age groups. A survey was therefore carried out among professional interpreters, students of interpreting and people who regularly attend conferences. The respondents were asked to answer a questionnaire after listening to three speeches: three consecutive interpretations delivered during the final exams held at the Advanced School of Languages, Literature, Translation and Interpretation (SSLLTI) in Forlì. Since conference interpreters’ public speaking skills should be at least as good as those of the speakers at a conference, the speeches were presented to the listeners as speeches delivered during a conference, with no mention of interpreting being made. The study is divided into five chapters. Chapter I outlines the characteristics of the interpreter as a professional communicator. The quality criterion “user-friendliness” is explored, with a focus on features that make a speech more user-friendly: fluency, intonation, coherence and cohesion. The Chapter also focuses on listeners’ quality expectations and evaluations. In Chapter II the methodology of the study is described. Chapter III contains a detailed analysis of the texts used for the study, focusing on those elements that may irritate listeners or impede comprehension, namely disfluencies, the wrong use of intonation and a lack of coherence or cohesion. Chapter IV outlines the results of the survey, while Chapter V presents our conclusions.

Lessons in Software Evolution Learned by Listening to Smalltalk

The biggest challenge facing software developers today is how to gracefully evolve complex software systems in the face of changing requirements. We clearly need software systems to be more dynamic, compositional and model-centric, but instead we continue to build systems that are static, baroque and inflexible. How can we better build change-enabled systems in the future? To answer this question, we propose to look back to one of the most successful systems to support change, namely Smalltalk. We briefly introduce Smalltalk with a few simple examples, and draw some lessons for software evolution. Smalltalk's simplicity, its reflective design, and its highly dynamic nature all go a long way towards enabling change in Smalltalk applications. We then illustrate how these lessons work in practice by reviewing a number of research projects that support software evolution by exploiting Smalltalk's design. We conclude by summarizing open issues and challenges for change-enabled systems of the future.

Query Technologies and Applications for Program Comprehension

Industrial software systems are large and complex, both in terms of the software entities and their relationships. Consequently, understanding how a software system works requires the ability to pose queries over the design-level entities of the system. Traditionally, this task has been supported by simple tools (e.g., grep) combined with the programmer's intuition and experience. Recently, however, specialized code query technologies have matured to the point where they can be used in industrial situations, providing more intelligent, timely, and efficient responses to developer queries. This working session aims to explore the state of the art in code query technologies, and discover new ways in which these technologies may be useful in program comprehension. The session brings together researchers and practitioners. We survey existing techniques and applications, trying to understand the strengths and weaknesses of the various approaches, and sketch out new frontiers that hold promise.

Listening to your heart and feeling yourself: effects of exposure to interoceptive signals during the ultimatum game

The ultimatum game (UG) is commonly used to study the tension between financial self-interest and social equity motives. Here, we investigated whether experimental exposure to interoceptive signals influences participants' behavior in the UG. Participants were presented with various bodily sounds--i.e., their own heart, another person's heart, or the sound of footsteps--while acting both in the role of responder and proposer. We found that listening to one's own heart sound, compared to the other bodily sounds: (1) increased subjective feelings of unfairness, but not rejection behavior, in response to unfair offers and (2) increased the unfair offers while playing in the proposer role. These findings suggest that heightened feedback of one's own visceral processes may increase a self-centered perspective and drive socioeconomic exchanges accordingly. In addition, this study introduces a valuable procedure to manipulate online the access to interoceptive signals and for exploring the interplay between viscero-sensory information and cognition.

Attention affects prospective memory performance in dichotic listening paradigm

The current study was designed to test for the effect of lateralized attention on prospective memory performance in a dichotic listening task. The practice phase of the experiment consisted of a semantic decision task during which the participants were presented with different words on either side via headphones. Depending on the experimental condition the participants were required to focus on the words presented on the left or right side and to decide if these words were abstract or concrete. Thereafter, the participants were informed about the prospective memory task. They were instructed to press a distinct key whenever they hear a word which denotes an animal in the same task later during the experiment. The participants were explicitly informed that the prospective memory cues could appear on either side of the headphones. This was followed by a retention interval which was filled with unrelated tasks. Next, the participants performed the prospective memory task. The results revealed more prospective hits for the attended side. The finding suggests that noticing a prospective memory cue is not an automatic process but requires attention.

Peripheral responses to attended and unattended angry prosody: a dichotic listening paradigm.

We investigated the effects of angry prosody, varying focus of attention, and laterality of presentation of angry prosody on peripheral nervous system activity. Participants paid attention to either their left or their right ear while performing a sex discrimination task on dichotically presented pseudo-words. These pseudo-words were characterized by either angry or neutral prosody and presented stereophonically (anger/neutral, neutral/anger, or neutral/neutral, for the left/right ear, respectively). Reaction times and physiological responses (heart period, skin conductance, finger and forehead temperature) in this study were differentially sensitive to the effects of anger versus neutral prosody, varying focus of attention, and laterality of presentation of angry prosody.

Cue Recognition and Integration - Eye Tracking Evidence of Processing Differences in Sentence Comprehension in Aphasia

PURPOSE: We aimed at further elucidating whether aphasic patients' difficulties in understanding non-canonical sentence structures, such as Passive or Object-Verb-Subject sentences, can be attributed to impaired morphosyntactic cue recognition, and to problems in integrating competing interpretations. METHODS: A sentence-picture matching task with canonical and non-canonical spoken sentences was performed using concurrent eye tracking. Accuracy, reaction time, and eye tracking data (fixations) of 50 healthy subjects and 12 aphasic patients were analysed. RESULTS: Patients showed increased error rates and reaction times, as well as delayed fixation preferences for target pictures in non-canonical sentences. Patients' fixation patterns differed from healthy controls and revealed deficits in recognizing and immediately integrating morphosyntactic cues. CONCLUSION: Our study corroborates the notion that difficulties in understanding syntactically complex sentences are attributable to a processing deficit encompassing delayed and therefore impaired recognition and integration of cues, as well as increased competition between interpretations.
