Background: The Positive Affect and Negative Affect Schedule (PANAS) has been used worldwide as a valid and consistent instrument to investigate the bidimensional structure of affect. Researchers can adapt PANAS from English to other languages by developing a new scale or translating directly from the original. This review describes and evaluates t...

This study presents the development of the Brazilian-Portuguese Affect Scale based on the development procedures of the PANAS (Positive Affect and Negative Affect Schedule). We applied psycholinguistic and validity procedures to reduce an affective Brazilian lexicon with 404 words. The reduction was based on familiarity, state/trait categorization...

Attention is a basic human function underlying every other cognitive process. It is demonstrated in the functional Magnetic Resonance Imaging literature that frontoparietal networks are involved with attentive performance while default mode networks are involved with inattentive performance. Yet, it is still not clear whether similar results would...

Social distancing in response to the COVID-19 pandemic brought several modifications in our daily lives. With these changes, some people have reported alterations in their feelings of how fast time was passing. In this study, we assessed whether and how social distancing and the evolution of the COVID-19 pandemic influenced participants' time aware...

The investigation of time-related activity in human electrophysiological activity has recently expanded from signals during the estimated interval to post-interval activity. Previous findings show timing-associated event-related potentials (ERPs) in both early (~150ms) and late positive components (LPC; ~300ms) post-interval signals. However, it is...

Social distancing in response to the Covid-19 pandemic brought several modifications in our daily lives. With these changes, some people have reported alterations in their feelings of how fast time was passing. In this study, we assessed whether and how social distancing influenced participants' time awareness and production of time intervals. Part...

We examined equivalence-based N400 effects by comparing EEG data from participants with different experiences with equivalence testing. Before a priming task used in EEG measurement, Group 1 was given only matching-to-sample training trials whereas Group 2 was exposed to matching-to-sample training and equivalence probe trials. We asked whether exp...

Here we advance the proposal that in addition to the importance of emotion words, the dynamics of allostatic regulation play a central role in emotion concept development. We argue for a comprehensive extension of constructed emotion theory to emotional development. To do so, we emphasize possible mechanisms for emotion concept differentiation that...

Dense longitudinal experience sampling studies with adults have shown that high emotional granularity scores are associated with better emotion regulation skills and lower prevalence of some psychiatric symptoms and disorders. Given the inherent difficulty in data acquisition, investigations applying this same methodology during development are sti...

This paper aimed to verify evidences of validity and reliability of Luria-Nebraska Test for Children (TLN-C, in Portuguese). Three hundred eighty-seven students aged 6–13 years old, with learning difficulties, comprised the study. They were assessed with the Wechsler Intelligence Scale for Children (WISC-III) and TLN-C; and effect of age difference...

This study sought evidences of validity of the Luria-Nebraska Test for Children (TLN-C) in its relation to education and intelligence. The participants were 120 children with learning difficulties (2st to 6th grades) assessed with the TLN-C and the Wechsler Intelligence Scale for Children-Third Revision. Results showed influence of education and in...
