To verify whether hesitation phenomena are distributed periodically in spontaneous speech, twenty speech samples produced by five male adults were analyzed. Spectral analysis allowed for three main findings. First, hesitations present stationary behavior, which implies they did not accumulate in the beginning, in the middle, or in the end of speech samples. Second, periodic cycles of hesitation...

The current work deals with the modelling of one type of disfluency, hesitations. A perceptual experiment using speech synthesis was designed to evaluate two duration features found to be correlates to hesitation, pause duration and final lengthening. A variation of F0 slope before the hesitation was also included. The most important finding is that it is the total duration increase that is the...

Can we assign attitudes to a computer based on its beeps? If so, which kinds of beeps are perceived as specific attitudes, such as " disagreement " , " hesitation " or " agreement " ? To examine this issue, I carried out an experiment to observe how participants perceive or assign an attitude to a computer according to beeps of different durations and F0 con-tour's slopes. The results revealed ...

| 2017 | 1 To conclude, considering the fact that getting immunized with a vaccine can be a difference between life and death, it is quite essential that we provide people with the reliable information on vaccination safety, especially through Internet, as it is the most preferred source of option accessed by people in the current era. This will neutralize all incidents of vaccine hesitancy and...

This systematic review describes the current relationship between health literacy (HL) and vaccination (including attitude to vaccines, intention to vaccinate, and vaccine uptake). The aim is to comprehend the role of HL as a determinant of vaccine hesitancy. For this purpose, the following databases were explored from 1 January 2007 to 15 January 2017: PubMed, Embase, PsycINFO, ERIC, Health Ev...

We ask whether lexical hesitations in spontaneous speech tend to precede words that are difficult to predict. We define predictability in terms of both transition probability and entropy, in the context of an N-gram language model. Results show that transition probability is significantly lower at hesitation transitions, and that this is attributable to both the following word and the word hist...

In this study, we used a case study approach to obtain an in-depth understanding of the change process of two university instructors who were involved with redesigning a biology course. Given the hesitancy of many biology instructors to adopt evidence-based, learner-centered teaching methods, there is a critical need to understand how biology instructors transition from teacher-centered (i.e., ...
