Hierarchical perception of melody
2009
Two experiments were designed to investigate the hierarchical perception of melodies. The hierarchical structure of tonal melodies is formally described in Lerdahl and Jackendoff's Generative Theory of Tonal Music (GTTM). The experiments were designed to assess different aspects of GTTM time span reduction quantitatively. Subjects were presented with pairs of melodies in a same-different task. A short novel and a longer original tonal melody could differ within the harmonic context at single tones on one of four time span reduction levels. It was found that detection rate of the melodic deviances correlated strongly with time span level. The same method was employed on an atonal and a poorl…
Improving Hand Hygiene Behavior Using a Novel Theory-Based Intervention During the COVID-19 Pandemic
2022
Abstract Background Promoting the adoption of personal hygiene behaviors known to reduce the transmission of COVID-19, such as avoiding touching one’s face with unwashed hands, is important for limiting the spread of infections. Purpose We aimed to test the efficacy of a theory-based intervention to promote the avoidance of touching one’s face with unwashed hands to reduce the spread of COVID-19. Methods We tested effects of an intervention employing imagery, persuasive communication, and planning techniques in two pre-registered studies adopting randomized controlled designs in samples of Australian (N = 254; Study 1) and US (N = 245; Study 2) residents. Participants were randomly assigned…
Funktionskreis e Gestaltkreis: la metafora del circolo nella biologia teoretica
2014
This paper aims to examine the use of the circle metaphor within the functionalist perspective by Jakob von Uexküll and the morphological perspective by Viktor von Weizsäcker. Whereas the functionalist theory dissolves the unity of the organism in the multiplicity of functional relationships, Weizsäcker’s morphology recognizes the fundamental unity of the biological act, leading to a new concept of the living organism.
Pseudo-relatives, gerunds and infinitives in Romance: (only) superficial resemblances and structural connections
2013
L'argomento di questa monografia è un confronto tra i costrutti predicativi di tipo frasale nelle diverse varietà romanze. Mentre le pseudorelative sono diffuse pressoché in tutta la Romània, con qualche variazione parametrica minore, i gerundi predicativi e gli infiniti preposizionali sono usati solo in alcune varietà. Negli studi linguistici sull'argomento è mancata finora l'ottica comparativa, sia tra varietà diverse, sia tra costrutti predicativi diversi. Il mio lavoro si prefissa lo scopo di colmare questa lacuna, senza ignorare però i costrutti percettivi composti da un infinito semplice, che da parte della letteratura sono stati paragonati alle strutture predicative delle pseudorelat…
Investigating teachers’ dyadic self-efficacy and its correlations to students’ perceptions of teacher efficacy and student well-being
2022
Most studies, to date, have ignored variance in teachers’ self-efficacy (TSE) in relation to teaching individual students (i.e., student-specific self-efficacy). However, TSE and teacher efficacy differ among students. Thus, this study examines dyadic TSE in four domains and their correlations with students’ perceptions of teacher efficacy and student academic self-concept and well-being. Results of a paper–pencil survey involving 29 teachers and 469 students (39.9% girls, aged 10–17 years) from German secondary schools reveal a moderate overlap between dyadic TSE and students’ perceptions of teacher efficacy. Furthermore, they reveal variance in how teachers’ and students’ ratings are rela…
Isomorphism and Mirror Neurons
2007
This paper aims to give a constructive contribution to Eagle & Wakefield's con-tention ( Gestalt Theory 29, 59-64) that the Gestaltists' hypotheses regarding isomorphism andphenomenological direct access to other's mind anticipate recent accounts of mind-readingability. I attempt to specify the extent to which Gestalt psychology might be seen to be consistentunder certain respects with mirror neurons system theory and embodied simulation theory,claimed to be founding the aforementioned ability. Therefore, empirical and theoretical issues such as the neurobiological features of the mirrorneuron system, the psychological explanation of its functions, and the features of the embodied simulatio…
Tapology: A Game-Based Platform to Facilitate E-Health and E-Inclusion
2014
Published version of a chapter in the book: Universal Access in Human-Computer Interaction. Aging and Assistive Environments. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-319-07446-7_36 We have developed a tablet computer game app for low vision users that can be used to introduce a platform for gaming, internet and visual rehabilitation to older users who have not had prior experience with information communication technology (ICT). Our target user group is people diagnosed with Age Related Macular Degeneration (AMD). The primary goal of the app is to present a fun and engaging means for participants to engage with Information Communication Technology (ICT). A long…
An Empirical Examination of the Economics of Mobile Application Security
2021
The growth of mobile devices coupled with the advances in mobile technologies has resulted in the development and widespread use of a variety of mobile applications (apps). Mobile apps have been developed for social networking, banking, receiving daily news, maintaining fitness, and for job-related tasks. The security of the apps is an important concern. However, in some cases, the app developers may be less interested to invest in the security of the apps, if users are unwilling to pay for the added security. In this paper, we empirically examine whether consumers are less willing to pay for security features than for usability features. In addition, we examine whether a third-party certif…
Lost or not? : designing and evaluating user interfaces of mobile map services : the viewpoint of supporting users' location awareness
2016
The motivation for this thesis arose from the problem of people getting lost, both with and without mobile maps. I will answer a primary research question: 1) How can we support users’ location awareness with mobile map applications? As an ad-dition to this, I have the following sub-questions: a) Why do people get lost even when using a mobile map application? b) What are the best practices to support navigation? c) How can we research what the important objects in the natural environment are that should be emphasized in mobile maps? d) How do we prevent the user from focusing on the map service at the expense of perceiving the location in the real environment? e) What would a good mobile m…
Customers' Perceived Risk and Trust in Using Mobile Money Services—an Empirical Study of Ghana
2019
Although mobile money (MM) has been explored in the existing literature, the roles of trust and risk in MM use have received little attention from researchers. Furthermore, many of the existing studies have treated these constructs as unidimensional. The extant literature also shows that perceived risk has received little attention from researchers who have conducted studies on MM. Thus, the objective of this study is to examine the roles of trust and perceived risk in customers' intent to adopt MM services in Ghana. Both trust and perceived risk were broken down into various dimensions. The study involved 671 respondents who were selected via an intercept approach and an online survey. Str…
