Music in the moment? Revisiting the effect of large scale structures.
2007
The psychological relevance of large-scale musical structures has been a matter of debate in the music community. This issue was investigated with a method that allows assessing listeners' detection of musical incoherencies in normal and scrambled versions of popular and contemporary music pieces. Musical excerpts were segmented into 28 or 29 chunks. In the scrambled version, the temporal order of these chunks was altered with the constraint that the transitions between two chunks never created local acoustical and musical disruptions. Participants were required (1) to detect on-line incoherent linking of chunks, (2) to rate aesthetic quality of pieces, and (3) to evaluate their overall co…
Attachment anxiety and avoidance and perceptions of group climate: an actor-partner interdependence analysis.
2012
There is a lack of research examining group members’ attachment styles and group climate perceptions in the context of the attachment styles and group climate perceptions of the other group members. In the current study, the actor–partner interdependence model (APIM) was used to examine the relationships among (a) a group member’s attachment pattern, (b) the aggregated attachment patterns of the other group members, (c) a group member’s perceptions of the group’s climate, and (d) the aggregated group climate perceptions of the other group members. One hundred ten Italian graduate students in six 10-session interpersonal growth groups were studied. Group members filled out the Attachment Sty…
Parental modeling, education and children's sports and TV time: The ENERGY-project
2014
Abstract Objective We assessed whether differences in children's sports participation and television time according to parental education were mediated by parental modeling. Moreover, we explored the differences between parental and child reports on parental sports participation and television time as potential mediators. Methods 5729 children and 5183 parents participating in the EuropeaN Energy balance Research to prevent excessive weight Gain among Youth (ENERGY-project) during 2010 in seven European countries provided information on sports participation and television time using validated self-report questionnaires. Multilevel country-specific mediation models analyzed the potential med…
Struggling for inclusive education in the North and the South: educators' perceptions on inclusive education in Finland and Zambia.
2003
A survey assessed the perceptions of 1350 Zambian teachers and parents and 512 Finnish teachers regarding inclusive education and consequently the best placement for children with different disabilities. On the whole, perceptions varied but were quite critical. On inclusion in general, the regular (also termed "ordinary") Finnish teachers were the most critical group and the Finnish special education teachers the most optimistic. Most respondents felt that inclusive education enhances social justice. However, the pursuit of inclusion in practice, especially the guarantee of good and effective education for all, was seen as problematic. Compared with Finnish respondents, the Zambian responde…
Self-Perceptions of Sicilian Male Youth
1972
An Italian version of the AVA was included in the test battery for a pilot study of Project Talent in Sicily. Ss were 395 male students attending a public technical school in Palermo, Sicily. Profiles of basic self and social self-concepts, as well as the composite self-concept yielded by the AVA, were analyzed for the Sicilian sample. The latter were also compared with those for an American normative sample ( N = 7732). Two heavily concentrated clusters were noted in the self-perceptions of the Sicilians in contrast to those of the American sample which are more evenly distributed throughout the personality spheroid comprising the AVA model.
Visual simulation through different intraocular lenses using adaptive optics: Effect of tilt and decentration
2011
Purpose To analyze visual quality differences between intraocular lenses (IOLs) and assess the impact of IOL decentration and tilt on visual quality. Setting University of Valencia, Valencia, Spain. Design Cohort study. Methods The crx1 adaptive optics visual simulator was used to simulate the wavefront aberration pattern of 2 commercially available aspheric aberration-correcting IOLs (Acrysof IQ SN60WF and Tecnis ZA9003) and 2 spherical IOLs (Akreos Adapt and Triplato) in 5 situations: centered, decentered 0.2 mm and 0.4 mm, and tilted 2 degrees and 4 degrees. Monocular distance visual acuity at 100%, 50%, and 10% contrast and the depth of focus were measured. Results Ten eyes of 10 patien…
Simulated prototype of posterior chamber phakic intraocular lens for presbyopia correction.
2014
Purpose To evaluate the visual impact of adding different spherical aberration values to an Implantable Collamer Lens phakic intraocular lens (pIOL) to increase the depth of focus using an adaptive optics visual simulator. Setting University of Valencia, Valencia, Spain. Design Experimental study. Methods Wavefront aberrations in −3.00 D and −6.00 diopter (D) pIOLs were measured in vitro. Afterward, different simulated pIOL experimental prototypes were created along with variances in the spherical aberration. An adaptive optics visual simulator was used to simulate vision after the implantation of the different pIOL prototypes from their wavefront aberrations. The corrected distance visual …
Depth of focus through different intraocular lenses in patients with different corneal profiles using adaptive optics visual simulation
2011
PURPOSE: To evaluate the depth of focus with monofocal intraocular lenses (IOLs) in patients with different corneal profiles using adaptive optics (AO) visual simulation. METHODS: An AO visual simulator (crx1, Imagine Eyes) was used to simulate the aberration pattern of three monofocal IOLs (Acrysof IQ SN60WF [Alcon Laboratories Inc]; Akreos Adapt AO [Bausch & Lomb]; and Triplato [AJL Ophthalmic]) of different optic designs. Five groups were considered: patients without any corneal refractive surgery (normal cornea group) and with prior low and high myopic and hyperopic ablations (low myopic ablation, high myopic ablation, low hyperopic ablation, and high hyperopic ablation groups). De…
Caffeine Increases Strength and Power Performance in Resistance-trained Females During Early Follicular Phase
2020
The effects of 4 mg·kg−1caffeine ingestion on strength and power were investigated for the first time, in resistance-trained females during the early follicular phase utilizing a randomized, double-blind, placebo-controlled, crossover design. Fifteen females (29.8 ± 4.0 years, 63.8 ± 5.5 kg [mean ± SD]) ingested caffeine or placebo 60 minutes before completing a test battery separated by 72 hours. One-repetition maximum (1RM), repetitions to failure (RTF) at 60% of 1RM, was assessed in the squat and bench press. Maximal voluntary contraction torque (MVC) and rate of force development (RFD) were measured during isometric knee extensions, while utilizing interpolated twitch technique to measu…
Emotion recognition, emotional awareness and cognitive bias in individuals with bulimia nervosa
2008
Difficulties recognizing emotion have been reported for eating disordered individuals in relation to perception of emotions in others and emotional self-awareness. It remains unclear whether this is a perceptual or cognitive-affective problem. Clarification is sought and the question of a cognitive bias is addressed when interpreting facially expressed emotions. Twenty participants with bulimia nervosa (BN) and 20 normal controls (NC) were assessed for ability to recognize emotional and neutral expressions. Emotional self-awareness was also assessed. Significant differences were found for emotional self-awareness. For emotional faces, only a poorer recognition of the emotion, surprise, for …
