In vowel discrimination, commonly found discrimination patterns are directional asymmetries where discrimination is faster (or easier) if differing vowels are presented in a certain sequence compared to the reversed sequence. Different models of speech sound processing try to account for these asymmetries based on either phonetic or phonological properties. In this study, we tested and compared two of those often-discussed models, namely the Featurally Underspecified Lexicon (FUL) model (Lahiri and Reetz, 2002) and the Natural Referent Vowel (NRV) framework (Polka and Bohn, 2011). While most studies presented isolated vowels, we investigated a large stimulus set of German vowels in a more n…

Assessing attention allocation toward threat-related stimuli: a comparison of the emotional Stroop task and the attentional probe task

2003

This study examined the association of two widely used measures of attention allocation toward or away from threat-related stimuli: The emotional Stroop task and the attentional probe task. Fifty-three participants responded to computer versions of both tasks where stimuli were presented both subliminally and supraliminally. Thus, four indexes indicating attention allocation were computed for each participant. A correlation analysis showed that the attentional probe index and the emotional Stroop index were associated within each presentation mode while all other relations were nonsignificant. These results are discussed in terms of a distinction between preattentive and attentional process…

Children’s Emotions in Educational Settings: Teacher Perceptions from Australia, China, Finland, Japan and Spain

2019

The transition to formal education is a critical transition in children’s lives that has importance for socio-emotional and behavioral functioning. In the transition process, teachers are key players who work intensively with children and their families. This article focuses on teachers’ perceptions of children´s socio-emotional behavior during the transition from preschool to primary school. We collected qualitative teacher interviews from 112 teachers from five different countries—Australia, China, Finland, Japan and Spain. The research questions were: (1) How do teachers in the five countries perceive children’s abilities in expressing and regulating emotions. (2) How are children’s emot…

Découverte d'Arthropodes et de bivalves inédits dans le Permien continental (Lodévois, France)

1997

Resume Des Triopsides, Conchostraces, Insectes, Bivalves, pistes et terriers d'Arthropodes sont decouverts dans le Groupe saxonien considere longtemps comme quasi azoique. Ces fossiles sont pour la plupart inedits, au niveau de l'espece, de la famille et de l'ordre. Chez les Insectes, de nouveaux taxons comblent des lacunes temporelles considerables, allant du Jurassique au Permien. Les informations recueillies vont permettre de rediscuter certaines phylogenies et de reapprecier l'impact de la crise fini-permienne sur cette classe. La repartition des Insectes et des Conchostraces suggere de donner un âge Koungourien a Tatarien (Leonardien a Capitanien) au ≪ Saxonien ≫.

RESEARCH PAPER: Multiple Sexual Ornamentation Signals Male Quality and Predicts Female Preference in Minnows

2010

Sexual ornamentation often consists of multiple components. Different sexual signals may indicate different aspects of mate quality or reflect quality in different time scales. On the other hand, same signals can have a dual function and are used both in male–male competition and courtship. Many fish species are capable of rapidly altering their colouration (ephemeral colour changes), but this capability is usually ignored in sexual selection studies. Here, we used experimentally manipulated social environments to study the ephemeral colour changes in multicomponent sexual signals of male minnows (Phoxinus phoxinus) during male–male competition and female choice. We found that the dominant …

Intraguild interactions between egg parasitoids: window of opportunity and fitness costs for a facultative hyperparasitoid.

2013

We investigated intraguild interactions between two egg parasitoids of Nezara viridula (L.) (Heteroptera: Pentatomidae), Ooencyrtus telenomicida (Vassiliev) (Hymenoptera: Encyrtidae) and Trissolcus basalis (Wollaston) (Hymenoptera: Platygastridae), as the former has the potential to be a facultative hyperparasitoid of the latter. We assessed the suitability of N. viridula eggs for the development of O. telenomicida as a function of egg age when they were unparasitized, or had been attacked by T. basalis at different times prior to exposure to O. telenomicida females. Ooencyrtus telenomicida can exploit healthy N. viridula host eggs up to 5 days of age, just prior to the emergence of N. viri…

Ambiente comunitario y actitud hacia la autoridad: relaciones con la calidad de las relaciones familiares y con la agresión hacia los iguales en adol…

2014

El objetivo del presente estudio es explorar las relaciones entre la calidad de las relaciones familiares, la percepción del ambiente comunita-rio y la actitud de los adolescentes hacia la autoridad (policía, profesores) y normas sociales, en la predicción del bienestar subjetivo y un problema conductual de actualidad como es la agresión hacia los iguales. Para poner a prueba estas relaciones múltiples se ha utilizado una muestra de 554 adoles-centes de ambos sexos con edades comprendidas entre los 12 y los 16 años. Los datos se recogieron en dos tiempos con un intervalo temporal de 6 me-ses y se analizaron mediante el cálculo de modelos de ecuaciones estructu-rales, incluyendo un análisis …

Teachers’ Ability to Identify Children at Early Risk for Reading Difficulties in Grade 1

2017

The aim of the study was to investigate what kinds of assessment practices classroom teachers and special educational needs (SEN) teachers use in assessing first grade students' pre-reading skills (letter knowledge and phonological skills). Further, we investigated to what extent teachers were able to identify difficulties in pre-reading skills of the children with the lowest achievement scores. The accuracy of teacher ratings of students' pre-reading skills was studied by comparing teacher ratings to actual test scores. The data from two Finnish longitudinal studies were used: JLD sample (class teachers, n = 91; SEN teachers, n = 51; 200 students) and First Steps sample (class teachers, n …

Reading and Writing Skills in Adolescents With Autism Spectrum Disorder Without Intellectual Disability.

2021

The purpose of this study is to extend the knowledge about academic achievement in individuals with autism spectrum disorder (ASD). To this end, first, we analyzed differences in a wide range of reading and writing skills in adolescents with ASD without intellectual disability (ASD-WID) and adolescents with typical development (TD). Second, these two groups were compared on academic outcomes in core subjects and indicators of successful transition to secondary school. Third, the potential contribution of literacy skills to academic outcomes was examined in the two groups. Participants were 56 adolescents between 12 and 14 years old, 30 with ASD-WID and 26 with TD. Results showed no signific…

Task-related variation in communication of mothers and their sons with learning disability

1995

The purpose of the present study was to examine whether mother-child communication patterns vary as a function of the type of the task. Groups of learning disabled (LD=30) and normally achieving boys (NLD=30) were videotaped interacting with their mothers in two different tasks. The children were matched for age (8 to 11 year-olds) and for parent’s SES. The results indicated that the teaching task differentiated the groups more than did the story task. Academic character of the teaching task increased mothers’ task involvement in both groups. Mothers of the LD group showed, however, significantly more dominance and expressed less emotionality while teaching their child. Mothers’ interaction…
