Online Adaptation to Altered Auditory Feedback Is Predicted by Auditory Acuity and Not by Domain-General Executive Control Resources

2018

Published: 12 March 2018 When a speaker's auditory feedback is altered, he adapts for the perturbation by altering his own production, which demonstrates the role of auditory feedback in speech motor control. In the present study, we explored the role of auditory acuity and executive control in this process. Based on the DIVA model and the major cognitive control models, we expected that higher auditory acuity, and better executive control skills would predict larger adaptation to the alteration. Thirty-six Spanish native speakers performed an altered auditory feedback experiment, executive control (numerical Stroop, Simon and Flanker) tasks, and auditory acuity tasks (loudness, pitch, and …

Viittomantunnistuksen automaattisuuden mittaaminen Stroopin testillä suomalaisessa viittomakielessä

2017

Tämä pro gradu -tutkimus tarkastelee viittomantunnistuksen automaattisuutta suomalaisessa viit- tomakielessä. Tutkimuksen tarkoituksena on selvittää, miten varhainen viittomakielen omaksu- minen ja kuulostatus vaikuttavat viittomantunnistuksen automaattisuuteen. Tutkimuksessa verra- taan kolmea ryhmää, jotka eroavat toisistaan sekä kuulostatuksiltaan että viittomakielen omaksu- misen ajankohdiltaan. Tutkimusmenetelmänä käytetään Stroopin testiä, joka on laajalti käytössä oleva toiminnanohjauksen testi. Tutkimusta varten testistä laadittiin versio suomalaiselle viitto- makielelle. Testissä ärsykkeinä ovat väriviittomat, jotka on testivideolla värjätty viittoman mer- …

Best not to bet on the horserace: A comment on Forrin and MacLeod (2017) and a relevant stimulus-response compatibility view of colour-word contingen…

2018

International audience; One powerfully robust method for the study of human contingency learning is the colour-word contingency learning paradigm. In this task, participants respond to the print colour of neutral words, each of which is presented most often in one colour. The contingencies between words and colours are learned, as indicated by faster and more accurate responses when words are presented in their expected colour relative to an unexpected colour. In a recent report, Forrin and MacLeod (2017b, Memory & Cognition) asked to what extent this performance (i.e., response time) measure of learning might depend on the relative speed of processing of the word and the colour. With keypr…

Transcranial random noise stimulation over the primary motor cortex in PD-MCI patients: a crossover, randomized, sham-controlled study

2020

AbstractMild cognitive impairment (MCI) is a very common non-motor feature of Parkinson’s disease (PD) and the non-amnestic single-domain is the most frequent subtype. Transcranial random noise stimulation (tRNS) is a non-invasive technique, which is capable of enhancing cortical excitability. As the main contributor to voluntary movement control, the primary motor cortex (M1) has been recently reported to be involved in higher cognitive functioning. The aim of this study is to evaluate the effects of tRNS applied over M1 in PD-MCI patients in cognitive and motor tasks. Ten PD-MCI patients, diagnosed according to the Movement Disorder Society, Level II criteria for MCI, underwent active (re…

Patients with minimal hepatic encephalopathy show impaired mismatch negativity correlating with reduced performance in attention tests

2012

Attention deficit is an early event in the cognitive impairment of patients with minimal hepatic encephalopathy (MHE). The underlying mechanisms remain unclear. Mismatch negativity (MMN) is an auditory event-related potential that reflects an attentional trigger. Patients with schizophrenia show impaired attention and cognitive function, which are reflected in altered MMN. We hypothesized that patients with MHE, similarly to those with schizophrenia, should show MMN alterations related with attention deficits. The aims of this work were to assess whether (1) MMN is altered in cirrhotic patients with MHE, compared to those without MHE, (2) MMN changes in parallel with performance in attentio…

Attentional Biases and Vulnerability to Depression

1999

This study was designed to examine selective processing of emotional information in depression. It focuses on possible attentional biases in depression, and whether such biases constitute a cognitive vulnerability factor to suffer from the disorder or, on the contrary, they reflect a feature associated exclusively with the clinical level of depression. 81 participants were included in the study: 15 with a diagnosis of Major Depression; 17 were diagnosed as Dysthymia; 11 participants scored over 18 in the Beck Depression Inventory (Beck, Rush, Shaw, & Emery, 1979); 15 participants, in whom a sad mood state was induced by an experimental mood induction (Velten technique + music, or biographic…

The Effect of an enriched sport program on children's executive functions: the ESA program

2020

Purpose: The effects of physical exercise on executive functions (EFs) are well documented. EFs are involved in daily activities, and their development determines the quality of people’s future life, both in terms of mental health and quality of life. The purpose of the current paper is to evaluate the effects of a physical education program, elaborated within the Enriched Sports Activity Program (ESA Program), an Erasmus + Project, on EFs, namely, visuospatial working memory, inhibitory control, cognitive flexibility, and task switching. Method: Data were collected on November 2017 (t1) and May 2018 (t2). At t1, a sample of 357 children from four European countries (Italy, Germany, Lithuan…

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…

Modulation of higher-order olfaction components on executive functions in humans

2015

The prefrontal (PFC) and orbitofrontal cortex (OFC) appear to be associated with both executive functions and olfaction. However, there is little data relating olfactory processing and executive functions in humans. The present study aimed at exploring the role of olfaction on executive functioning, making a distinction between primary and more cognitive aspects of olfaction. Three executive tasks of similar difficulty were used. One was used to assess hot executive functions (Iowa Gambling Task-IGT), and two as a measure of cold executive functioning (Stroop Colour and Word Test-SCWT and Wisconsin Card Sorting Test-WCST). Sixty two healthy participants were included: 31 with normosmia and …
