The Relative Importance of Local and Global Structures in Music Perception

2004

Research in experimental psychology has emotion in music is developed by L. B. Meyer.2 shown two paradoxes in music perception. By According to Meyer, listeners are not passive, mere exposure to musical pieces, Western lis- but rather constantly develop perceptual expectteners acquire sensitivity to the regularities ancies about the possible evolution of the underlying tonal music. This implicitly acquired music. Emotions arise from the way the comknowledge allows listeners to perceive subtle poser (or the improvising performer) fulfills relations between musical events and permits or frustrates these expectancies. To some musically untrained listeners to behave as music- extent, music perc…

Do happy faces really modulate liking for Jackson Pollock art and statistical fractal noise images?

2017

Flexas et al. (2013) demonstrated that happy faces increase preference for abstract art if seen in short succession. We could not replicate their findings. In our first experiment, we tested whether valence, saliency or arousal of facial primes can modulate liking of Jackson Pollock art crops. In the second experiment, the emphasis was on testing another type of abstract visual stimuli which possess similar low-level image features: statistical fractal noise images. Pollock crops were rated significantly higher when primed with happy faces in contrast to neutral faces, but not differently to the no-prime condition. Findings of our study suggest that affective priming with happy faces may be…

Encoding into Visual Working Memory: Event-Related Brain Potentials Reflect Automatic Processing of Seemingly Redundant Information.

2013

Encoding and maintenance of information in visual working memory in an S1-S2 task with a 1500 ms retention phase were investigated by means of event-related brain potentials (ERPs). Participants were asked to decide whether two visual stimuli were physically identical (identity comparison (IC) task) or belonged to the same set or category of equivalent patterns (category comparison (CC) task). The stimuli differ with regard to two features. (1) Each pattern can belong to a set of either four (ESS 4) or eight (ESS 8) equivalent patterns, mirroring differences in the complexity with regard to the representational structure of each pattern (i.e., equivalence set size (ESS)). (2) The set of pat…

The Adequate Stimulus

2008

The term adequate stimulus describes that class of environmental phenomena that requires the least amount of energy to elicit a percept mediated by a particular sensory system, implying that the receptive organs of that sensory system are specialized to detect those phenomena. It was difficult to transfer this concept to the perception of pain and to the nociceptive system. Many different stimuli may cause pain (pin prick, burn injury, freeze injury, inflammation, etc.), none of which needs particularly low amounts of energy. The common denominator of those stimuli is that they threaten to cause tissue damage (in Greek: νoξη Noxe). Hence the adequate stimulus to elicit pain is traditionally…

Is it Quantum Sentience or Quantum Consciousness? A Review of Social Behaviours Observed in Primitive and Present-Day Microorganisms

2015

Social and intelligent behavioural designs have been observed in primitive and present day microorganisms in all three kingdoms of life. These behavioural patterns help microorganisms, to understand, evaluate and judge their constantly varying environment. Behaviour is represented as conscious moment, which occurs due to an event, which may be intentional or unintentional. Microorganisms have the capability of displaying behaviours, which can be compared to cognitive actions of the neural system in higher organisms. This review is a collection of social behaviours observed in present-day microorganisms as well as predicted behaviours in microfossils that have been studied so far. The intent…

Impact of training on beer flavor perception and description: Are trained and untrained subjects really different?

2001

This study examines the effect of beer assessment training on verbal and nonverbal performance. Two groups of subjects are asked to sort, match, and describe a set of 12 beers (6 supplemented and 6 commercial beers). Subjects from the first group are enrolled in a beer-training program. Subjects in the second group are untrained beer consumers. Results show that although both groups perform the matching task equally well, trained subjects performed better on supplemented beers and untrained subjects on commercial beers. Examination of the generated vocabulary shows that 44% of the terms are common to trained and untrained subjects. However, an analysis of the terms' efficiency shows that wh…

The effect of texture on face identification and configural information processing

2014

Shape and texture are an integral part of face identity. In the present study, the importance of face texture for face identification and detection of configural manipulation (i.e., spatial relation among facial features) was examined by comparing grayscale face photographs (i.e., real faces) and line drawings of the same faces. Whereas real faces provide information about texture and shape of faces, line drawings are lacking texture cues. A change-detection task and a forced-choice identification task were used with both stimuli categories. Within the change detection task, participants had to decide whether the size of the eyes of two sequentially presented faces had changed or not. After…

Exploring relationships between pianists’ body movements, their expressive intentions, and structural elements of the music

2011

Body movements during music performance have been found to be indicative of the performer’s musical intentionality, and contribute to an observer’s perception of expressive playing. This study investigates the effect of structural elements of the score, and the playing of different levels of expression on body movements during a piano performance. Pianists were required to play the same piece in four different performance conditions. Their movements were tracked by an optical motion capture system, and the comparisons that were made between specific parts of the body used, performance condition, and musical score locations were subsequently statistically examined. We found that the head an…

An eye tracking comparison of external pointing cues and internal continuous cues in learning with complex animations

2010

Abstract Two experiments used eye tracking to investigate a novel cueing approach for directing learner attention to low salience, high relevance aspects of a complex animation. In the first experiment, comprehension of a piano mechanism animation containing spreading-colour cues was compared with comprehension obtained with arrow cues or no cues. Eye tracking data revealed differences in learner attention patterns between the different experimental conditions. The second experiment used eye tracking with synchronized and non-synchronized cues to investigate the role of dynamic direction of attention in cueing effectiveness. Results of Experiment 1 showed that spreading-colour cues resulted…
