Phonemic awareness refers to sensitivity and intentional control over the smallest speech sounds, i.e., phonemes. Visual attention span refers to the amount of distinct visual elements (letters) that can be processed simultaneously within a given set. There are hardly any studies on these two skills and their role in reading performance among Brazilian Portuguese speakers. This study aims at verifying (1) the existence of relationships between the skills of VAS and phonemic awareness and their relations with the reading performance of Brazilian children and (2) whether these relations would modify during their schooling years. The sample was made up of 48 students (1st, 3rd and 5th grade) from a public elementary school in Sao Paulo (Brazil). Children were assessed in three sessions through a battery of tasks which included single word reading, phonemic awareness, VAS, nonverbal IQ, verbal short-term memory and letter identification threshold. Results showed that VAS and phonemic awareness correlated with performance in reading of regular and irregular words and nonwords from 1st to 5th grade of elementary school. They also indicated that VAS and phonemic awareness play a more important role at the beginning of the learning of reading, i.e., in 1st grade, but continue to be of importance to reading ability in 3rd and 5th grade especially in reading of nonwords. It was also observed that there is a development of reading skills, phonemic awareness and visual attention span with the progress in schooling / Estudos anteriores demonstraram que o desempenho em leitura depende das habilidades de consciência fonêmica e de amplitude visuo-atencional (AVA). A consciência fonêmica se refere à sensibilidade e controle intencional dos menores sons da fala, isto é, os fonemas. A amplitude visuo-atencional se refere à quantidade de elementos visuais distintos (letras) que podem ser processados simultaneamente dentro de um conjunto. Ainda são escassas as pesquisas sobre essas duas habilidades e seu papel no desempenho em leitura em falantes do português do Brasil. No presente estudo, verificou-se (1) a existência de relações entre as habilidades de AVA e de consciência fonêmica e o desempenho em leitura em crianças brasileiras e (2) se essas relações se modificavam com o progresso na escolarização. Participaram desse estudo 48 alunos do 1º ano, 3º ano e 5º ano do ensino fundamental de uma escola pública de São Paulo. As crianças foram avaliadas em três sessões por meio de uma bateria que incluía tarefas de leitura de palavras isoladas, tarefas de consciência fonêmica, tarefas de EVA, Q.I. não verbal, memória verbal de curto prazo e limiar de identificação de letras. Demonstrou-se que a AVA e a consciência fonêmica se correlacionam com o desempenho em leitura de palavras regulares, irregulares e pseudopalavras desde o 1º até o 5º ano do ensino fundamental. Os resultados indicam que a AVA e a consciência fonêmica desempenham um papel mais importante no 1º ano da aprendizagem da leitura, mas continuam tendo um papel relevante no 3º ano e no 5º ano principalmente na leitura de pseudopalavras. Observou-se também que ocorre uma evolução das habilidades de leitura, consciência fonêmica e amplitude visuoatencional com o progresso na escolarização

The world of digital marketing is advancing at a rapid rate, an ever so increasing number of individuals are connected to the world wide web and subsequently being exposed to marketing messages in the thousands each day. For marketers this poses a unique challenge when it comes to creating a marketing segment which conveys their message effectively by attaining the attention of the consumer. This in turn means that their marketing efforts may be lost in the digital sea of millions other impressions being thrown at the daily user. The purpose of this research paper is to therefore explore and gain greater understanding on how companies’ perception about consumer attention span could be, to then provide a perspective on how the modern marketer can work to incorporate this as a factor in their marketing. This research study was conducted through a qualitative methodology with a deductive approach which meant that theories were first gathered to then be compared with the empirical evidence consisting of three semi-structured interviews with chosen companies. The research indicated that modern marketers could benefit from understanding their target audience and catering their marketing message to suit their needs and values. Furthermore, constant measurement and analysis proved to be important in creating the best type of advertisement which captured the attention of the consumer. / Modern digital marknadsföring utvecklas i en väldigt snabb takt, allt fler individer är idag kopplade till internet och blir därigenom exponerade för tusentals marknadsföringsmeddelanden varje dag. För marknadsförare skapar detta en unik utmaning när det kommer till att skapa marknadsföring som förmedlar ett budskap effektivt genom att fånga konsumentens uppmärksamhet. Om marknadsföraren misslyckas här kan det leda till att deras meddelande försvinner bland de miljontals andra meddelanden som slängs mot konsumenten i den enorma digitala världen. Syftet med den här studien är därmed utforska och anskaffa mer förståelse gällande hur företags uppfattning om konsumenters uppmärksamhetsförmåga ser ut för att sedan erbjuda ett perspektiv för den moderna marknadsföraren om hur denne kan arbeta för att integrera detta som en faktor i sin marknadsföring. Den här forskningen genomfördes genom en kvalitativ metodologisk design där deduktiv ansats användes. Detta innebar att författarna först samlade teori som sedan jämfördes och analyserades tematiskt med den insamlade empirin som bestod av semi-strukturerade intervjuer av tre företag. Studien visade att den moderna marknadsföraren kan gynnas av att ha en djup förståelse av sin målgrupp för att kunna utforma marknadsföringssegment på ett sätt som passar deras behov och värderingar. Vidare påvisades även att det kan vara fördelaktigt att ständigt mäta och analysera marknadsföringsinsatser för att kunna förstå vad som fungerar och vad som borde förändras i framtiden just för att skapa marknadsföring som bättre fångar konsumenters uppmärksamhet.

Short attention spans are a growing phenomenon, impacting users in their daily interactions with technology. While there have been studies in the field of HCI on how to design for directing or maximizing user attention, few have focused on users with short attention spans and their felt experiences. To fill this research gap, this study employed a user-centered design approach involving a pre-study and a workshop concerning web design. A thematic analysis of the data revealed ten themes which, among other things, dealt with web navigation, overwhelming interfaces and distractions. The results showed that attention is an embodied experience and relying solely on quantitative data, such as eye tracking, may not provide a complete understanding of it. Therefore, involving those affected in the design process can assist designers in creating the best possible experience, aligning with the end-users’ own definition of what constitutes a good experience. Additionally, designers should adapt to minimalist design principles to meet the needs of this user group. This paper contributes to research by giving in-depth insights into the felt experiences of short attention spans, and how these experiences may be designed for. / Korta uppmärksamhetspann är ett växande fenomen som påverkar användare i deras dagliga interaktioner med teknologi. Även om det har gjorts studier inom HCI om hur man designar för att rikta eller maximera användares uppmärksamhet, har få fokuserat på användare med korta uppmärksamhetspann och deras erfarenheter. För att bidra med kunskap inom detta område, använde denna studie en användarcentrerad designmetodik som innefattade en förstudie och en workshop om webdesign. En tematisk analys av datan resulterade i tio teman som bland annat handlade om webnavigering, överväldigande gränssnitt och distraktioner. Resultatet visade att uppmärksamhet är en förkroppsligad upplevelse och att enbart förlita sig på kvantitativ data såsom eye-tracking inte nödvändigvis ger en fullständing representation. Involvera de berörda i designprocessen kan därför hjälpa designers att skapa den bästa möjliga upplevelsen, i linje med slutanvändarnas egen definition av vad som utgör en god upplevelse. Dessutom bör designers använda sig av minimalistiska designprinciper för att tillgodose behoven hos denna användargrupp. Denna artikel bidrar till forskningen genom att ge inblickar i de upplevda erfarenheterna av korta uppmärksamhetspann och hur dessa erfarenheter kan designas för.

Afrikaans text / Die doel van hierdie studie was om te bepaal wat die invloed van motoriese oefening op die leervermoë van die leerder in die grondslagfase is. Vyf en twintig leerders is ewekansig verdeel in `n eksperimentele en kontrole groep. Oor `n tydperk van vyf weke, voor die aanvang van elke leerafdeling, het die eksperimentele groep, saam met die onderwyseres, klaskamer gebaseerde motoriese oefeninge verrig terwyl die kontrole groep geen intervensie ontvang het nie. Die Copeland’s checklist for Attention Deficit Disorder vraelys is as voor- en natoets gebruik. Na die afloop van die empiriese ondersoek het die eksperimentele groep `n verbetering getoon in onoplettendheid/afleibaarheid, impulsiwiteit, ooraktiwiteit/hiperaktiwiteit, onderaktiwiteit en aandagvermoë, terwyl die kontrole groep oor dieselfde tydperk verswak het of onveranderd gebly het. Die veranderinge was egter nie statisties betekenisvol (p≤0.05) nie. Hierdie resultaat dui slegs op „n tedens dat motoriese oefening 'n positiewe effek op die leerders se leervermoë in die grondslagfase het. / Educational Studies / M. Ed. (Educational Studies)

Abstracts in Afrikaans and English / Inklusiewe onderrig ondersteun die insluiting van alle leerders met verskillende behoeftes en vaardighede in klaskamers, wat baie keer te groot, of te verskillend vir doeltreffende onderrig is. Beweging as deel van ‘n vroeë leerervaring is noodsaaklik vir optimale neurale ontwikkeling. Dit beïnvloed organisasie en stimuleer die spesifieke neurologiese sisteme nodig vir optimale funksionering en ontwikkeling van die brein. Sensoriese integrasie disfunksie word gesien as die wortel van baie leerprobleme. Die vestibulêre sisteem is direk verbind met die sensoriese en motoriese sisteme. ‘n Sensoriese integrasie disfunksie het ‘n duidelike invloed op die vestibulêre sisteem. Die vestibulêre sisteem het baie interkonneksies met baie dele in die brein, byvoorbeeld propriosepsie en die tassisteem. Doeltreffende funksionering van die sensoriese, motoriese en vestibulêre sisteme word verlang vir ‘n hoë vlak van prestasieverrigting in sport en akademie. Wanneer die vestibulêre sisteem gestimuleer word, het dit ‘n direkte positiewe invloed op die sensoriese en motoriese ontwikkeling van leerders. Die doel van hierdie studie was om te bepaal wat die persepsie van grondslagfase-onderwysers en ouers is oor die rol en voordele wat vestibulêre oefeninge te weeg kan bring in die motoriese en sensoriese ontwikkeling van leerders. Leerders in graad 1 van ‘n privaatskool, asook van grade 2 en 3 van ‘n plaasskool is gekies as deelnemers in die studie. Die keuse van leerders was op grond van die bereidwilligheid van hulle en hul ouers om aan die studie deel te neem. Leerders het ‘n vestibulêre oefenprogram drie maal per week gedoen vir die tydperk van agt weke. Observasie-vraelyste is deur onderwysers en ouers ingevul na afloop van die derde sessie elke week. Vir die vraelys het ouers en onderwysers gekyk na die verbetering in aandagspan, konsentrasie, luistervaardigheid, oogkontak, sosiale interaksie en samewerking. Onderhoude is met ouers en onderwysers gedoen na aanleiding van die observasievraelyste wat vir die agt weke voltooi is. Transkripsies van die onderhoude is gedoen en afleidings is gemaak deur analise van die observasie-vraelyste en die getranskribeerde onderhoude. Al ses die ontwikkelingsareas by beide skole het verbetering getoon oor die agt weke. Dit dui daarop dat vestibulêre oefeninge wel ‘n invloed op die sensoriese en motoriese ontwikkeling het. / Inclusive education promotes the inclusion of learners with different needs and capabilities in classes which are often too big and diverse for effective teaching. Movement as an early learning experience is necessary for optimal neural development. It influences organisation and stimulates the specific neurological systems required for optimal functioning and development of the brain. Sensory integrative dysfunction is believed to be at the root of many learning disorders. The vestibular system is directly connected with the sensory and motor systems. The vestibular system will be directly affected when a sensory integrations dysfunction presents. In fact, the vestibular system has many interconnections with almost every other part of the brain like proprioception and the tactile system. Proper functioning of the sensory, motor and vestibular systems is required for higher level performance in sport and academics. When the vestibular system is stimulated, it will result in a positive influence on the sensory and motor development of learners. The aim of this study is to determine the perceptions of foundation phase teachers and parents regarding the role or benefits of vestibular exercises in promoting learners’ motor and sensory development. Learners in Grade 1 of a private school and Grade 2 and 3 learners of a farm school in the northern Free State were selected as participants in the research. Learners were selected on the basis of the willingness of them and their parents to participate in the research. The participants did exercise sessions three times a week for thirty minutes over a period of eight weeks. Observation sheets were completed for all eight weeks, for the duration of the exercise program, by teachers and parents. These sheets were completed weekly after the third sessions in that week. The observation sheets listed concentration, attention span, listening, eye contact, cooperation, social interaction and self-esteem as developmental areas. Interviews were done after the period of eight weeks with the parents and teachers. The interviews conducted with both parties were taped and meticulously transcribed. This helped the researcher to get a better understanding of the study and to analise data and draw conclusions.All six areas of development showed improvement at both schools over the period of eight weeks. This indicates that stimulating the vestibular system promotes sensory and motor development. / Inclusive Education / M. Ed. (Inklusiewe Onderwys)
