The soundslide report : innovative journalism or misplaced works of art?
2014
Published version of an article in the journal: Nordicom Review. Also available from the publisher at: http://dx.doi.org/10.2478/nor-2014-0007 Open Access The audio slideshow-or soundslide report-represents a new format for journalistic reporting on online news sites. It is not very widely used, but it has certain discursive and aesthetic potentials indicating that it could contribute substantially to the ecology of journalistic genres. The article offers an illustration and discussion of these potentials, asking how the format communicates and how it affects journalism in general. Starting out with a close reading of a sample text and a discussion of the format's position in a network of g…
The Mona Lisa effect: Neural correlates of centered and off-centered gaze
2014
The Mona Lisa effect describes the phenomenon when the eyes of a portrait appear to look at the observer regardless of the observer's position. Recently, the metaphor of a cone of gaze has been proposed to describe the range of gaze directions within which a person feels looked at. The width of the gaze cone is about five degrees of visual angle to either side of a given gaze direction. We used functional magnetic resonance imaging to investigate how the brain regions involved in gaze direction discrimination would differ between centered and decentered presentation positions of a portrait exhibiting eye contact. Subjects observed a given portrait's eyes. By presenting portraits with varyin…
Transposed-Letter Priming Effects for Close Versus Distant Transpositions
2009
Transposing two internal letters of a word produces a perceptually similar item (e.g., CHOLOCATE being processed as CHOCOLATE). To determine the precise nature of the encoding of letter position within a word, we examined the effect of the number of intervening letters in transposed-letter effects with a masked priming procedure. In Experiment 1, letter transposition could involve adjacent letters (chocloate-CHOCOLATE) and nonadjacent letters with two intervening letters (choaolcte-CHOCOLATE). Results showed that the magnitude of the transposed-letter priming effect – relative to the appropriate control condition – was greater when the transposition involved adjacent letters than when it i…
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…
Position Coding in Two-Digit Arabic Numbers
2011
Digit position coding in two-digit Arabic numbers was examined in two masked priming experiments. In Experiment 1, participants had to decide whether the presented stimulus was a two-digit Arabic number (e.g., 67) or not (e.g., G7). Target stimuli could be preceded by a prime which (i) shared one digit in the initial position (e.g., 13-18), (ii) shared one digit but in a different position (83-18), and (iii) was a transposed number (81-18). Two unrelated control conditions, equalized in terms of the distance between primes and targets with the experimental conditions, were also included (e.g., 79-18). Results showed a priming effect only when prime and target shared digits in the same posi…
Vetting and verifying multimodal false information. A challenge for democratic societies
2021
The rapid proliferation of fake news is a challenge for free societies, founded on freedom of expression and information, endangering their democratic systems through audience confusion. Fake news is a type of disinformation with the ability to alter the logical orientation of readers, and as evidenced in different academic publications, it can radicalize the citizen and favour violence. This news is also created to confuse audiences and reinforce certain trends. This is important enough to produce a scientific interest in information science studies and urge the creation of tools capable of detecting and identifying this type of news, especially those disseminated by social networks, where…
Educación XX1 : revista de la Facultad de Educación
2018
La siguiente investigación pretende analizar en qué medida los recursos educativos, en este caso los libros de texto, contribuyen a la alfabetización visual del alumnado de Educación Primaria en Ciencias Sociales. Este tipo de alfabetización es un aspecto fundamental en cualquier etapa educativa tal y como ha venido confirmando la investigación hasta fechas muy recientes. Para ello se han seleccionado los manuales más utilizados en un determinado espacio geográfico desde 2006 y se han analizado siguiendo un método de investigación que combina procedimientos cuantitativos (ex post-facto) y cualitativos (análisis mediante categorías conceptuales) aplicándolos sobre las actividades relacionada…
