Observational research and verbal protocol methods

This paper describes observational research and verbal protocols methods, how these methods are applied and integrated within different contexts, and how they complement each other. The first case study focuses on nurses’ interaction during bandaging of patients’ lower legs. To maintain research rigor a triangulation approach was applied that links observations of current procedures, ‘talk-aloud’ protocol during interaction and retrospective protocol. Maps of interactions demonstrated that some nurses bandage more intuitively than others. Nurses who bandage intuitively assemble long sequences of bandaging actions while nurses who bandage less intuitively ‘focus-shift’ in between bandaging actions. Thus different levels of expertise have been identified. The second case study consists of two laboratory experiments. It focuses on analysing and comparing software and product design teams and how they approached a design problem. It is based on the observational and verbal data analysis. The coding scheme applied evolved during the analysis of the activity of each team and is identical for all teams. The structure of knowledge captured from the analysis of the design team maps of interaction is identified. The significance of this work is within its methodological approach. The maps of interaction are instrumental for understanding the activities and interactions of the people observed. By examining the maps of interaction, it is possible to draw conclusions about interactions, structure of knowledge captured and level of expertise. This research approach is transferable to other design domains. Designers will be able to transfer the interaction maps outcomes to systems and services they design.

Relationship between emotional climate and the fluency of classroom interactions

This study examined emotional climate in relation to the teaching and learning of grade 7 science. A multi-method and multi-theoretic approach used sociocultural frameworks as a foundation for interpretive research, conversation analysis, prosody analysis, and studies of nonverbal conduct. Emotional climate varied continuously throughout a lesson. Dialogues occurred and afforded learning when interactions between the teacher and students were fluent and included humour and collective effervescence. Emotional climate was negatively valenced when the teacher and/or students endeavoured to establish and maintain power by restricting others’ participation to spectator roles. The teacher’s endeavours to maintain and establish control over students were potentially detrimental to teaching and learning, teachers and learners. This type of teaching gradually evolved into a form we referred to as cranky teaching, whereby the teacher and her students showed signs of frustration and the enacted teaching and learning roles lacked fluency. The methods we pioneered in the present study might be helpful for other teachers who wish to participate in research on their classes to ascertain what works and should be strengthened, and identify practices and rituals that are deleterious and in need of change.

Dissociating verbal and nonverbal audiovisual object processing

This fMRI study investigates how audiovisual integration differs for verbal stimuli that can be matched at a phonological level and nonverbal stimuli that can be matched at a semantic level. Subjects were presented simultaneously with one visual and one auditory stimulus and were instructed to decide whether these stimuli referred to the same object or not. Verbal stimuli were simultaneously presented spoken and written object names, and nonverbal stimuli were photographs of objects simultaneously presented with naturally occurring object sounds. Stimulus differences were controlled by including two further conditions that paired photographs of objects with spoken words and object sounds with written words. Verbal matching, relative to all other conditions, increased activation in a region of the left superior temporal sulcus that has previously been associated with phonological processing. Nonverbal matching, relative to all other conditions, increased activation in a right fusiform region that has previously been associated with structural and conceptual object processing. Thus, we demonstrate how brain activation for audiovisual integration depends on the verbal content of the stimuli, even when stimulus and task processing differences are controlled.

Comparison of IQS and verbal-performance IQ discrepancies estimated from two seven-subtest short forms of the WAIS-R

The present study compared IQs and Verbal-Performance IQ discrepancies estimated from two seven-subtest short forms of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) in a sample of 100 subjects referred for neuropsychological assessment. The short forms of Warrington, James, and Maciejewski (1986) and Ward (1990) yielded similar correlation coefficients and absolute error rates with respect to WAIS-R IQs, although the Warrington short form requires more time to administer and score. Both short forms were able to detect significant Verbal-Performance IQ discrepancies 70% of the time. However, they incorrectly yielded significant discrepancies for approximately 25% of the sample who did not have significant differences on the full WAIS-R. The results do not support reporting and interpreting significant Verbal-Performance IQ discrepancies estimated from these short forms.

Cerebral regions associated with verbal response initiation, suppression and strategy use

Cerebral activation associated with performance on a novel task involving two conditions was investigated with functional magnetic resonance imaging (fMRI). In the response initiation condition, subjects nominated the general superordinate category to which each of a series of exemplars (concrete nouns) belonged. In the response suppression condition, subjects were required to nominate a general superordinate category to which each exemplar did not belong, with the instruction that they were not to nominate the same category response twice in a row. Both conditions produced distinct patterns of activation relative to an articulation control condition employing identical stimuli. When initiation and suppression conditions were directly compared, response suppression produced activation in the right frontal pole, orbital frontal cortex and anterior cingulate, left dorsolateral prefrontal cortex and posterior cingulate, and bilaterally in the precuneus, visual association cortex and cerebellum. Response latencies were significantly longer in the suppression condition. Two broadly-defined strategies associated with the correct production of words during the suppression condition were a self-ordered selection from among the superordinate categories identified during the first section of the task and the generation of novel category responses. The neuroanatomical correlates of response initiation, suppression and strategy use are discussed, as are the respective roles of response suppression and strategy generation.

Climbing skill and complexity of climbing wall design: Assessment of jerk as a novel indicator of performance fluency

This study investigated a new performance indicator to assess climbing fluency (smoothness of the hip trajectory and orientation of a climber using normalized jerk coefficients) to explore effects of practice and hold design on performance. Eight experienced climbers completed four repetitions of two, 10-m high routes with similar difficulty levels, but varying in hold graspability (holds with one edge vs holds with two edges). An inertial measurement unit was attached to the hips of each climber to collect 3D acceleration and 3D orientation data to compute jerk coefficients. Results showed high correlations (r = .99, P < .05) between the normalized jerk coefficient of hip trajectory and orientation. Results showed higher normalized jerk coefficients for the route with two graspable edges, perhaps due to more complex route finding and action regulation behaviors. This effect decreased with practice. Jerk coefficient of hip trajectory and orientation could be a useful indicator of climbing fluency for coaches as its computation takes into account both spatial and temporal parameters (ie, changes in both climbing trajectory and time to travel this trajectory)

Semantic Fluency in Mild and Moderate Alzheimer's Disease

Alzheimer's disease (AD) is characterized by an impairment of the semantic memory responsible for processing meaning-related knowledge. This study was aimed at examining how Finnish-speaking healthy elderly subjects (n = 30) and mildly (n=20) and moderately (n = 20) demented AD patients utilize semantic knowledge to performa semantic fluency task, a method of studying semantic memory. In this task subjects are typically given 60 seconds to generate words belonging to the semantic category of animals. Successful task performance requires fast retrieval of subcategory exemplars in clusters (e.g., farm animals: 'cow', 'horse', 'sheep') and switching between subcategories (e.g., pets, water animals, birds, rodents). In this study, thescope of the task was extended to cover various noun and verb categories. The results indicated that, compared with normal controls, both mildly and moderately demented AD patients showed reduced word production, limited clustering and switching, narrowed semantic space, and an increase in errors, particularly perseverations. However, the size of the clusters, the proportion of clustered words, and the frequency and prototypicality of words remained relatively similar across the subject groups. Although the moderately demented patients showed a poor eroverall performance than the mildly demented patients in the individual categories, the error analysis appeared unaffected by the severity of AD. The results indicate a semantically rather coherent performance but less specific, effective, and flexible functioning of the semantic memory in mild and moderate AD patients. The findings are discussed in relation to recent theories of word production and semantic representation.

Colours as Non-Verbal Signs on Packages

Colour is an essential aspect of our daily life, and still, it is a neglected issue within marketing research. The main reason for studying colours is to understand the impact of colours on consumer behaviour, and thus, colours should be studied when it comes to branding, advertising, packages, interiors, and the clothes of the employees, for example. This was an exploratory study about the impact of colours on packages. The focus was on low-involvement purchasing, where the consumer puts limited effort into the decision-making. The basis was a scenario in which the consumer faces an unpredictable problem needing immediate action. The consumer may be in hurry, which indicate time pressure. The consumer may lack brand preferences, or the preferred brand may be out of stock. The issue is that the choice is to be made at the point of purchase. Further, the purchasing involves product classes where the core products behind the brands are indistinguishable from each other. Three research questions were posed. Two questions were answered by conjoint analysis, i.e. if colours have an impact on decision-making and if a possible impact is related to the product class. 16 hypothetical packages were designed in two product classes within the healthcare, i.e. painkillers and medicine against sore throats. The last research question aimed at detecting how an analysis could be carried out in order to understand the impact of colours. This question was answered by conducting interviews that were analysed by applying laddering method and a semiotics approach. The study found that colours do indeed have an impact on consumer behaviour, this being related to the context, such as product class. The role of colours on packages was found to be threefold: attention, aesthetics, and communication. The study focused on colours as a means of communication, and it proposes that colours convey product, brand, and product class meanings, these meanings having an impact on consumers’ decision-making at the point of purchase. In addition, the study demonstrates how design elements such as colours can be understood by regarding them as non-verbal signs. The study also presents an empirical design, involving quantitative and qualitative techniques that can be used to gain in depth understanding of the impact of design elements on consumer behaviour.

Formas inter-comunicacionais em Pedro Nava: o signo verbal e o pictórico

Esta pesquisa, contribuindo para os estudos em Literatura Comparada, evidencia a correlação entre Literatura e Artes Plásticas, que tem sido vista desde a Antigüidade quando ícones da analogia entre o verbal e o pictórico deixaram suas marcas na correspondência entre as artes. Tal correlação atravessou vários períodos da História e continua presente em inúmeras pesquisas, na época contemporânea. Este trabalho examina a especificação teórica de vários escritores relacionados ao tema e enfoca principalmente as formas como Pedro Nava (1903-1984) utilizou os artifícios verbal e pictórico ao lidar com duas artes distintas

O aspecto verbal em Vidas Secas: subsídios gramaticais para o estudo da construção narrativa

Esta pesquisa tem como objetivo investigar a categoria do tempo interno ou aspecto verbal na organização narrativa do romance Vidas Secas, de Graciliano Ramos. Repassa-se criticamente, com base na leitura de algumas obras representativas, a contribuição tradicional ao estudo desse conceito, mesmo nos casos em que não é identificado pelo termo aspecto. Em seguida, foram abordados a conceituação da categoria do aspecto verbal e alguns conceitos sobre a semântica do perfectivo e do imperfectivo segundo estudos empreendidos por linguistas diversos. Abordou-se ainda a variedade de meios de expressão do aspecto: o lexical, o sintático, o derivacional e o flexional. No segundo momento, procedeu-se a uma análise da funcionalidade textual do aspecto como recurso de organização do texto narrativo. Para tanto, foram levados em conta os conceitos de gênero textual e de modo de organização do discurso. Estes comentários tiveram por objeto o primeiro e o nono capítulos do romance, respectivamente Mudança e Baleia

A leitura da tira de quadrinhos: para uma gramática contrastiva do não verbal com o verbal

O objetivo desta tese foi sugerir à prática didática subsídios que possam contribuir com a condução da leitura de Tiras de Quadrinhos. Promove-se a ideia de que é possível elaborar uma gramática contrastiva do não verbal a partir da gramática do verbal, na consideração de que a leitura da imagem deve estar maciçamente atrelada à vivência diária do ser humano. Perspectivas da Linguística textual, da Semiótica peirceana e da Gramática tradicional foram entrelaçadas para obter-se um suporte teórico julgado eficaz na sustentação da hipótese de que a leitura multifacetada oferecida pela Tira de Quadrinhos é promissora quanto à formação de leitores proficientes. Fazem parte dessa conjuntura a Análise da conversação, a Organicidade do tópico discursivo, a Iconicidade diagramática e focalizações fonéticas, morfológicas e sintáticas envolvidas pelo semântico. No amálgama da tradição com a modernidade, sugeriram-se análises e interpretações da imagem no contexto linguístico-textual. O corpus é constituído de Tiras de Quadrinhos, publicadas diariamente no jornal O Globo, referentemente ao período de cinco anos, de 2005 a 2009

Processamento mental da concordância verbal em estruturas do português brasileiro: investigação de possível interferência em sentenças com elemento movido sintaticamente

Muitos trabalhos têm buscado compreender como se dá o processamento da concordância entre sujeito e verbo e investigar fatores que possam influenciar a produção correta da concordância, gerando os chamados erros de concordância verbal. Franck et al (2010) realizaram pesquisa na língua francesa e encontraram interferência devido a elemento movido sintaticamente na produção da concordância verbal. Se faz necessário investigar se o fenômeno envolvendo movimento é o mesmo em sentenças do português brasileiro. Sendo assim, nosso objetivo foi investigar uma possível interferência de cópia de número plural entre sujeito e verbo (em relação de concordância) de elemento movido sintaticamente em construção de árvore sintática do PB, observando a origem do erro e tentando mostrar se há autonomia do formulador sintático. Ao propormos o diálogo entre Teoria Linguística e Psicolinguística utilizando o Programa Minimalista, versão mais atual do Gerativismo de Chomsky, a fim de observar a derivação sintática e o processamento das sentenças, acreditamos que o estudo de formulação sintática e um olhar por meio de um modelo de processamento, que abarquem tanto a formulação como a produção, esclareceriam a nós pontos importantes sobre o funcionamento da concordância verbal. A nossa hipótese é a de que um erro de concordância verbal não ocorra devido ao formulador sintático em estruturas de PB, buscaremos respostas para isso no modelo MIMC (Modelo Integrado Misto da Computação On-Line) (Corrêa & Augusto, 2007). No entanto, por outro lado, se um erro de concordância ocorre, tentaremos encontrar uma outra explicação que não proveniente da sintaxe, tal como, por exemplo, devido a aspecto de ordem morfofonológica e devido a tamanho da sentença, como colocado pelo modelo PMP (Modelo de Processamento Monitorado por parser (Rodrigues, 2006). À medida que realizamos dois experimentos com sentenças declarativa e interrogativa com o movimento do elemento DP e QU, os resultados mostram que o tamanho da sentença e fatores morfofonológicos podem produzir interferência devido ao tipo de elemento movido. Os resultados cedem terreno para assumir um formulador sintático autônomo e abre caminho para próximas investigações sobre o processamento da concordância verbal e possíveis interferências durante a sua produção
