Some years ago Cheung et al. (2008) proposed the complete design (CD) for measuring the failure of selective attention in composite objects. Since the CD is a fully balanced design, analysis of response bias may reveal potential effects of the experimental manipulation, the stimulus material, and/or attributes of the observers. Here we used the CD to prove whether external features modulate perception of internal features with the context congruency paradigm (Nachson et al., 1995; Meinhardt-Injac et al., 2010) in a larger sample of N = 303 subjects. We found a large congruency effect (Cohen's d = 1.78), which was attenuated by face inversion (d = 1.32). The congruency relation also strongly…

Influencia de la velocidad de nombramiento en el inicio de la lectura

2016

Abstract:The analysis of the cognitive processes that are the basis of reading skill has detected some predictors of the development of phonological-orthographic skills necessary in learning it and has identified the naming speed as a good predictor of deficit related to reading difficulties. The objective of this study is to analyze the relationship between naming speed and initial learning of literacy through the analysis of aspects such as the influence of the reading habits, age of onset of literacy or participation in specific learning methods as Kumon. The study involved 289 children aged 4 to 6 years. Results showed naming speed correlates with phonological awareness, predicts readin…

Relative age and perceptions of soccer specific skills among elite youth players in Norway

2019

One common feature among the selected players in talent development programs are the well-known relative age effect (RAE), characterized by a skewed birth distribution among selected players with an over-representation of players born early in the selection year. The aim of the present study was to examine potential differences in soccer-specific skills between players selected for national talent program born in the first half of the year compared to the players born in the second half of the year. A total of 753 elite male U 14 (N = 363) and U 13 players (N = 390) from 16 of 18 soccer regions in Norway participated. The results showed players born early in the selection year considered th…

Covariation between reading and arithmetic skills from grade 1 to grade 7

2017

This study examined the extent to which reading and arithmetic skills show covariation at Grade 1 and at Grade 7, to what extent this covariation is time-invariant or time-specific, and to what extent different antecedents will predict these time-invariant and time-specific portions of the covariation. The reading and arithmetic skills of a total of 1335 Finnish children were assessed at the end of Grade 1 and then again at the end of Grade 7. Phonological awareness, letter knowledge, rapid automatized naming (RAN), counting, and parental education levels were measured in kindergarten; working memory at Grade 1 and nonverbal reasoning at Grade 3. The results showed that reading and arithmet…

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…

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…

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

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…
