Does orthographic processing emerge rapidly after learning a new script?
2021
Epub 2020 Aug 11 Orthographic processing is characterized by location-invariant and location-specific processing (Grainger, 2018): (1) strings of letters are more vulnerable to transposition effects than the strings of symbols in same-different tasks (location-invariant processing); and (2) strings of letters, but not strings of symbols, show an initial position advantage in target-in-string identification tasks (location-specific processing). To examine the emergence of these two markers of orthographic processing, we conducted a same-different task and a target-in-string identification task with two unfamiliar scripts (pre-training experiments). Across six training sessions, participants …
Sport participation and vigilance in children: Influence of different sport expertise
2018
PURPOSE: The present study aimed to investigate the relationship between different types of sport expertise (externally-paced vs. self-paced sports) and vigilance performance in children by evaluating the cardiovascular fitness level of the participants. METHODS: Three groups of children (11.0 ± 0.2 years) differentiated in terms of their regular sport participation (football players, n = 20; track and field athletes, n = 20; non-athletic controls, n = 20) took part in the study. In one session, participants performed the Leger Multi-stage fitness test to estimate their aerobic fitness level. In another session, participants completed the Psychomotor Vigilance Task (PVT) to evaluate their v…
The relationship between observed and perceived assessments of the coach-created motivational environment and links to athlete motivation
2016
Abstract Objectives The majority of research examining the relationship between the coach-created motivational and athlete motivation has relied on self-report measures. Grounded in Duda’s (2013) theoretically integrated model, the present study examined: (1) athletes', coaches' and observers' reports of the multidimensional motivational coaching environment in four European countries, (2) the interrelationships of these different perspectives of the motivational environment, and (3) links between the multidimensional environment and athletes' autonomous, controlled and amotivation. Design We employed a cross-sectional study design and utilized mixed methods to tap the variables of interest…
What drives increases in hindsight impressions after the reception of biased media content?
2021
Prior research has shown that reading biased media content (e.g., Wikipedia articles) can increase recipients' hindsight bias. It remained unclear, however, which features of the biased texts led to such an increase. We examined this question in a longitudinal experimental study (N = 190). Specifically, we tested whether repeated exposure to already known information (H₁), a more coherent presentation of the information (H₂), or the presentation of novel information (H₃) affected readers' hindsight impressions of likelihood, inevitability, and foreseeability. To this end, participants initially learned about an event by reading several short news, and, 1 week later, received one of several …
Speech technology as an experimental science: towards the comparative dynamics of Sprechkunde in Germany and Russia in the late nineteenth to early t…
2016
The article examines various resonances of the “speech technology” (Sprechkunde) current in German and Russian-Soviet context of 1900–1920s. It contains first of all a brief history of the techniques of speech in Germany, an inquiry into some psychophysical sources of the “speech technology” and a survey of the contribution of German “new rhetoric” to this movement. The Russian counterparts of this trend include the Institute of the Living Word (Institut živogo slova, 1918–1923), some Russian formalists, the scenic speech specialists and the theatre pedagogues. The conclusion summarises the historical significance of “speech technology” and its common features in Germany and Russia. It turn…
Human Sensorimotor Communication: A Theory of Signaling in Online Social Interactions
2013
Although the importance of communication is recognized in several disciplines, it is rarely studied in the context of online social interactions and joint actions. During online joint actions, language and gesture are often insufficient and humans typically use non-verbal, sensorimotor forms of communication to send coordination signals. For example, when playing volleyball, an athlete can exaggerate her movements to signal her intentions to her teammates (say, a pass to the right) or to feint an adversary. Similarly, a person who is transporting a table together with a co-actor can push the table in a certain direction to signal where and when he intends to place it. Other examples of ``si…
Questions raised in science education : a Colombian-Spanish comparative study
2016
RESUMEN: La formulación de preguntas es un potente recurso para el aprendizaje de las ciencias. El objetivo del presente trabajo fue evaluar el desarrollo de la competencia metacognitiva por medio de la formulación de preguntas. En este estudio se usaron dos dispositivos experimentales de ciencias con un comportamiento inesperado. Se pidió a los participantes realizar preguntas destinadas a comprender su funcionamiento. La evaluación contrastó el desempeño de estudiantes colombianos con estudiantes españoles equivalentes. Los resultados mostraron que los colombianos formulan significativamente más preguntas en general, y más preguntas de alta calidad, que los estudiantes españoles. Se concl…
Levels of cognitive congruence between managers and team members’ perceptions of cooperation at work
2019
Much of the research on the psychological dynamics of performance teams suffers from the following limitations: consideration of only one theoretical framework and analysis of just one perspective (e.g., manager&ndash
Measuring music-induced emotion: A comparison of emotion models, personality biases, and intensity of experiences
2011
Most previous studies investigating music-induced emotions have applied emotion models developed in other fields to the domain of music. The aim of this study was to compare the applicability of music-specific and general emotion models – namely the Geneva Emotional Music Scale (GEMS), and the discrete and dimensional emotion models – in the assessment of music-induced emotions. A related aim was to explore the role of individual difference variables (such as personality and mood) in music-induced emotions, and to discover whether some emotion models reflect these individual differences more strongly than others. One hundred and forty-eight participants listened to 16 film music excerpts a…
A functional MRI study of happy and sad emotions in music with and without lyrics
2011
Musical emotions, such as happiness and sadness, have been investigated using instrumental music devoid of linguistic content. However, pop and rock, the most common musical genres, utilize lyrics for conveying emotions. Using participants’ self-selected musical excerpts, we studied their behavior and brain responses to elucidate how lyrics interact with musical emotion processing, as reflected by emotion recognition and activation of limbic areas involved in affective experience. We extracted samples from subjects’ selections of sad and happy pieces and sorted them according to the presence of lyrics. Acoustic feature analysis showed that music with lyrics differed from music without lyric…
