Chronotype, Time of Day, and Children's Cognitive Performance in Remote Neurops...
Bettencourt, Catarina; Pires, Luís Miguel; Almeida, Filipa; Vilar, Manuela; Cruz, Hugo; Leitão, José; Gomes, Ana AllenResearch on the influence of chronotype and time of day (TOD) on cognitive performance, especially in children, is limited. We explored potential interactive effects, hypothesizing that performance differs when comparing preferred vs. non-preferred TOD. In total, 76 morning-type (MT = 37) or evening-type (ET = 39) children from the third and fourth grades (48.7% girls; M age = 8.05; SD age = 0.51), identified t...
Downy mildew evaluation in wild rocket genotypes (<i>Diplotaxis tenuifolia</i> ...
Coelho, P. S.; Pereira, A. L.; Reis, João; Carranca, C.; Lopes, V. R.; Leitão, JoséWild rocket downy mildew (DM) is a foliar disease caused by the oomycete Hyaloperonospora spp. that limits the production of brassicas, especially in temperate climates, infecting plants at all growth stages. During 2021 autumn season, a field trial (polytunnel) with a set of 40 wild rocket accessions from different origins (harvest missions, gene banks, commercial cultivars) was installed in a commercial enter...
Processing Underpinnings of Chronotype x Time-of-Day Interactions: A Study of a...
Leitão, José; Pires, Luís; Santos, Isabel; Guerrini, Chiara; Gomes, AnaChronotype and time-of-day interactions are often manifest in differences between performance at times-of-day matching the individual's chronotype (on-peak) and off-peak performance. However, it is not clear which processing variables determine whether on- or off-peak benefits/costs will occur. We hypothesized that only processes entangled by conditional automaticity (CA) would manifest (a)synchrony effects: on...
Conditional Automaticity and Age-related Modulations of (A)synchrony Effects in...
Leitão, JoséChronotype and time-of-day interactions are often manifest in differences between performance at times-of-day matching the individual's chronotype (on-peak) and off-peak performance. However, it is not clear which processing variables determine whether on- or off-peak benefits/costs will occur, nor how does ageing (young adult vs older adult) affect chronotype and time-of-day interactions. In this study, we use...
Momentary emotional states in primary school children: combined effects of chro...
Almeida, Filipa; Pires, Luís; Bettencourt, Catarina Carreiro; Almeida, Rita; Ruivo Marques, Daniel; Leitão, José; Gomes, Ana Cardoso AllenSynchrony effects regarding mood diurnal fluctuations (i.e., better mood at optimal and worse mood at suboptimal times-of-day, corresponding to the interaction between chronotype* time-of-day) have been studied in adolescents and adults. However, evidence in children is lacking. We investigated the interactive effect of chronotype and time-of-day on primary school children’s momentary emotional states, in a nat...
Downy mildew resistance and genetic variability in a wild rocket germplasm coll...
Coelho, Paula S.; Reis, João M.; Pereira, Ana L.; Vairinhos, Aliana; Lopes, Violeta; Leitão, JoséOne hundred accessions of a "core collection" of Diplotaxis tenuifolia (L.) DC. and Eruca spp. were screened at seedling stage for resistance to downy mildew. Accessions tested at the seedling stage were assigned to 0-6 interaction phenotypes. All cultivated rocket (Eruca spp.) accessions exhibited a resistant (R) response both in cotyledons and in young leaves. The wild rocket (D. tenuifolia) accessions exhibi...
Assessment of Wild Rocket (Diplotaxis tenuifolia (L.) DC.) Germplasm accessions...
Reis, João M.; Pereira, Ricardo; Coelho, Paula S.; Leitão, JoséRocket is the common designation for two baby-leaf salad crops of the Brassicaceae family: Eruca sativa (L.) Cav., usually referred to as annual garden rocket, and Diplotaxis tenuifolia (L.) DC. commonly named to as perennial wild rocket. E. sativa is used for human consumption since antiquity. However, the growing consumer preference for D. tenuifolia is being accompanied by the fast increase in its production...
A Non-rogue mutant line induced by ENU mutagenesis in paramutated rogue peas (P...
Pereira, Ricardo; Leitão, JoséThe spontaneously emerging rogue phenotype in peas (<i>Pisum sativum</i> L.), characterized by narrow and pointed leaf stipula and leaflets, was the first identified case of the epigenetic phenomenon paramutation. The crosses of homozygous or heterozygous (e.g., F1) rogue plants with non-rogue (wild type) plants, produce exclusively rogue plants in the first and all subsequent generations. The fact that the wil...
Abstracts of the 25th Congress of the European Sleep Research Society, 22-24 Se...
Pires, Luis; Couto, Diana; Cruz, Hugo Miguel Fernandes; Bettencourt, Catarina; Leitão, José; Azevedo, Maria Helena; Marques, Daniel RuivoObjectives/Introduction: IQ tests are extensively used in school settings to evaluate children's specific cognitive deficits that may contribute to low academic achievement. Some studies found that IQ assessments’ results can vary according to testing time and chronotype. The present study aimed to probe potential chronotype X time of day (ToD) interactive effects on children's IQ results. Methods: Sixty-eight ...
O contributo do associativismo para a valorização da Educação Física no Estado ...
Alencar, Dioniso; Leitão, José; Oliveira, António; Lima, Danilo; Pereira, AntoninoDurante o percurso de criação dos primeiros cursos de Educação Física no Estado do Ceará - Brasil e da expansão da intervenção profissional surge a necessidade dos Professores de Educação Física se organizarem em associações, surgindo o associativismo na Educação Física do Estado do Ceará. O objeto de estudo desta pesquisa foram as Associações de Professores/Profissionais de Educação Física do Estado do Ceará, ...
