We introduce a biologically motivated, formal framework or “ontology” for dealing with many aspects of action discovery which we argue is an example of intrinsically motivated behaviour (as such, this chapter is a companion to that by Redgrave et al. in this volume). We argue that action discovery requires an interplay between separate internal forward models of prediction and inverse models ma...

Noises made before the acoustic onset of speech are typically ignored, yet may reveal aspects of speech production planning and be relevant to discourse turn-taking. We quantify the nature and timing of such noises, using an experimental method designed to elicit naturalistic yet controlled speech initiation data. Speakers listened to speech input, then spoke when prompt material became visible...

This paper deals with a prosodic comparison of spontaneous and read-aloud speech. More speci cally, the study reports data on F0 declination in these two speaking modes using Swedish materials. For both speaking styles the analysis revealed negative slopes, a steepness-duration dependency with declination being less steep in longer utterances than in shorter ones and resetting at utterance boun...

Speech communication is embedded in many daily activities. In this paper we investigate the effect of biking on respiratory and speech parameters. Breathing and speech production were recorded in eleven subjects while speaking alone and while speaking and biking with different rates. Breathing frequency, speaking rate, speech and pause intervals, overall intensity and f0 were analyzed for the d...

Salim El Rouayheb and Kannan Ramchandran introduced the concept of fractional repetition (FR) code. In their article it remained unsolved when we can find such codes. Here we give an exact characterization of situations when it is possible to find an FR code. I. THE EXISTENCE OF FR CODES The definition of fractional repetition code, introduced in [1], is the following. Definition 1.1: A Fractio...

after weakening of traditional presence of rhythm and rhyme in poem and introducing of new issues and challenges, the necessity of using the capacity and various tools for indicating concepts received more attention. poets by using different elements struggled to communicate with their audience properly. one of these elements derived from music is repetition which is so brilliant in ahmad matar...

Repetition suppression in fMRI studies is generally thought to underlie behavioural facilitation effects (i.e., priming) and it is often used to identify the neuronal representations associated with a stimulus. However, this pays little heed to the large number of repetition enhancement effects observed under similar conditions. In this review, we identify several cognitive variables biasing re...

Numerous studies have shown that repetition of search-relevant attributes facilitates visual search performance. For example, Maljkovic and Nakayama (1994) showed that when observers search for a target defined by its color and report its shape, repetition of the target color speeds search, an effect known as priming of pop-out. While intertrial feature priming in search was initially thought t...

In four experiments, a total of 384 undergraduates incidentally learned a list of 24 nouns twice in the same context (same-context repetition) or different contexts (different-context repetition). Free recall was measured in a neutral context. Experiments 1, 2, and 3 used a context repetition (same- or different-context repetition) × inter-study and retention intervals (10 min or 1 day) between...

Repeating an item in a brief or rapid display usually produces faster or more accurate identification of the item (repetition priming), but sometimes produces the opposite effect (repetition blindness). We present a theory of short-term repetition effects, the competition hypothesis, which explains these paradoxical outcomes. The central tenet of the theory is that repetition produces a represe...
