This thesis focuses on the mapping of the microphone array’s response to match the characteristics of a human subject’s Head-Related Transfer Function (HRTF). The mapping of the response is first explored with a ‘monaural HRTF matching’ that filters the response independent of the arrival angles. For arbitrary array geometry with the listener external to the acoustic, the monaural HRTF matching did not provide listeners with enough spatial information to precisely localize sound sources. To correct this, a preprocessor control algorithm was added to the HRTF matching, a ‘binaural HRTF matching’ process. The binaural HRTF matching increased the listeners’ performance in perceiving the location of a sound source. With the addition of simulated head movement, the listeners’ perception increased by 20%. An issue with this approach is the use of HRTFs other than the listeners’ measured HRTF, creating a psychoacoustic based error in localization, i.e., front/back confusion. / Master of Science

Despite this, the speaker's behavior has been more emphasized and studied The aim of this study was to analyze the bibliographic production carried out by behavior analysts about the listener's behavior, as a mediator of consequences and while audience to the speaker's behavior, from the year of publication of Verbal Behavior and work through both articles published in international journals as JEAB, JABA, The Behavior Analyst and TAVB as in national journals as REBAC and RBTCC. It was analyzed 70 articles, of which 62 dealt with the listener as a mediator of consequences, while 7 audience and one treated both concepts. It was observed that articles about the listener's behavior (listener and audience) began to markedly small measure, the first published 26 years after the Verbal Behavior. Over the years the publications of articles geared to the study of these concepts have been increasing, as a result of the contribution of authors like Caio F. Miguel, R. Douglas Greer and Anna Ingeborg Petursdottir. With regard to the type of research, it was noted a balance between theoretical and conceptual research and experimental research and among the experimental research it was observed that the listener's behavior has been studied both as an independent variable as the dependent variable. Moreover, in both types of research the listener's behavior was studied more as a central object than a secondary object. Finally, there is the listener's behavior was notorious presence on subject-matters such as the relationship between the repertoire of the listener and the speaker, stimulus equivalence, verbal operant tact and naming. Summarizing the development of this field of research, it highlights two assertions of Skinner himself (1957/1992) regarding the understanding of verbal behavior that influenced a timid start, but also contributed to advances in research: on the one hand, verbal behavior was to focus the explicit individual speaker and postulated by Skinner (19957/1992), on the other hand, there is the need for the listener's behavior be closely analyzed so that a complete understanding of verbal behavior is achieved / Em Verbal Behavior (1957), B. F. de Skinner propõe uma análise minuciosa do comportamento verbal especificando a relação entre o comportamento do falante e o comportamento do ouvinte. Apesar disto, o comportamento do falante tem sido mais enfatizado e estudado O objetivo do presente estudo foi o de analisar a produção bibliográfica realizada pelos analistas do comportamento acerca do comportamento do ouvinte, enquanto mediador de consequências e enquanto audiência para o comportamento do falante, a partir do ano de publicação da obra Verbal Behavior e através dos artigos publicados tanto em periódicos internacionais como JEAB, JABA, The Behavior Analyst e TAVB como em periódicos nacionais como REBAC e RBTCC. Foram analisados 70 artigos, dos quais 62 trataram do ouvinte enquanto mediador de consequências, 7 enquanto audiência e 1 tratou em ambos os conceitos. Observou-se que artigos a respeito do comportamento do ouvinte (ouvinte e audiência) iniciaram-se de forma marcadamente acanhada, sendo o primeiro publicado 26 anos após o Verbal Behavior. No decorrer dos anos as publicações de artigos voltados ao estudo desses conceitos vêm aumentando, resultado este devido a contribuição de autores como Caio F. Miguel, R. Douglas Greer e Anna Ingeborg Petursdottir. No que diz respeito ao tipo de pesquisas, notou-se um equilíbrio entre pesquisas teórico-conceituais e pesquisas experimentais e dentre as pesquisas experimentais observou-se que o comportamento do ouvinte vem sendo estudado tanto como variável independente quanto como variável dependente. Além disso, em ambos os tipos de pesquisas o comportamento do ouvinte foi estudado mais como objeto central do que como objeto secundário. Por fim, destaca-se que o comportamento do ouvinte foi presença notória em temas como relação entre o repertório do ouvinte e do falante, equivalência de estímulos, operante verbal tato e nomeação. Sumarizando o desenvolvimento deste campo de investigação, destacam-se duas asserções do próprio Skinner (1957/1992) com relação a compreensão do comportamento verbal que influenciaram um início tímido, mas que também contribuíram para os avanços das pesquisas: se por um lado, o comportamento verbal teve como enfoque o falante individual explícito e postulado por Skinner (19957/1992), por outro lado, há a necessidade de o comportamento do ouvinte ser analisado de perto para que uma compreensão completa do comportamento verbal seja alcançada

We see an inclusion of the listener in the construction of programs, is exposing their life stories, commenting on facts, answering questions, choosing subjects and participating in some form of radio programming. This insertion of the listener in radio programs is generally thought of as a constituent element of the message. This study aims to analyze the participation of the listener and the forms of interaction in the " Debates of the People" that thirty- past two years is the schedule for CBN Fortaleza. The investigation was conducted through observation in studio, interview, transcription, content analysis and association analysis. This is a qualitative and quantitative research while. We found that the listeners of the program had no acceptance of interactive tools such as the Internet and social networks to make their holdings. In clipping analyzed, we noted that the participation of the listener was selected according to their relationship and proximity to the topic discussed. Also detected that the opinion is superior to the listener questions on the topic. The presenter has the function to put the questions in the listener program. Among the public comments are questions and opinions on the subject and speaks of the debaters.

Syftet med uppsatsen är att få en grundligare kunskap om berättande. I uppsatsen kan man läsa om vad författare anser om berättandets betydelse, medias påverkan på fantasin och vilka skyldigheter pedagoger har. Jag har även intervjuat tre pedagoger, från förskolan och skolans yngre år. Pedagogerna har givit en förståelse om hur berättande kan användas i praktiken och vilken betydelse de anser att berättande har för barnen. Jag har kommit fram till att berättande används i alla dess former ute i de verksamheter jag har besökt och är uppskattat från både lärare och barn. Jag kom också fram till att berättande hjälper barn att utveckla sitt språk, minne och fantasi. Men att viss media, d.v.s. dator och television, kan göra fantasin lat och hämma den språkliga utvecklingen. / The purpose of the essay is to get a thorough knowledge about narration. You can read about different authors’ opinions about narration, its significance, and the influence media has on the imagination and the duties educationists have. I’ve also interviewed three different educationists, from both pre-school and the early ages of school. They have provided insights about how to use narration in school, and the importance they think narration has for the children. The results show that narration is used in many forms an appreciated by both teachers and children. I’ve also discovered that narration helps children to develop their language skills, their memory and their imagination. But some media, like the computer and the television, could make the imagination lazy and obstruct the linguistic development.
