Abstract Background: The association of attention-deficit/hyperactivity disorder (ADHD) and tic disorder (TD) is frequent and clinically important. Very few and inconclusive attempts have been made to clarify if and how the combination of ADHD+TD runs in families. Aim: To determine the first time in a large-scale ADHD sample whether ADHD+TD increases the risk of ADHD+TD in siblings and, also the first time, if this is independent of their psychopathological vulnerability in general. Methods: The study is based on the International Multicenter ADHD Genetics (IMAGE) study. The present sub-sample of 2815 individuals included ADHD-index patients with co-existing TD (ADHD+TD, n=262) and without …

Wearing glasses to hear differently? Aftereffects of visuomanual prismatic adaptation on auditory perception

2022

Sensorimotor plasticity is defined as the ability to produce an appropriate motor response face to environmental or bodily changes. The classical experimental paradigm to study sensorimotor plasticity is prism adaptation, which consists of pointing to visual targets while wearing prisms that shift the visual field laterally or vertically. Its aftereffects are not restricted to sensorimotor behavior but extend to sensorial modalities not directly involved during prism exposition, such as audition. There exists a mental representation of auditory frequencies in which low auditory frequencies are associated with the left part of space and high auditory frequencies with the right part of space.…

Effort in Semi-Automatized Subtitling Processes

2020

The presented study investigates the impact of automatic speech recognition (ASR) and assisting scripts on effort during transcription and translation processes, two main subprocesses of interlingual subtitling. Applying keylogging and eye tracking, this study takes a first look at how the integration of ASR impacts these subprocesses. 12 professional subtitlers and 13 translation students were recorded performing two intralingual transcriptions and three translation tasks to evaluate the impact on temporal, technical, and cognitive effort, and split-attention. Measures include editing time, visit count and duration, insertions, and deletions. The main findings show that, in both tasks, ASR…

A multicentre randomized controlled trial on trans-generational attention deficit/hyperactivity disorder (ADHD) in mothers and children (AIMAC): an e…

2018

Abstract. Objective: We examined predictors and moderators of treatment outcome in mothers and children diagnosed with ADHD in a large multicentre RCT. Method: In total, 144 mother-child dyads with ADHD were randomly assigned to either a maternal ADHD treatment (group psychotherapy and open methylphenidate medication, TG) or to a control treatment (individual counselling without psycho- or pharmacotherapy, CG). After maternal ADHD treatment, parent-child training (PCT) for all mother-child dyads was added. The final analysis set was based on 123 dyads with completed primary outcome assessments (TG: n = 67, CG: n = 56). The primary outcome was the change in each child’s externalizing sympto…

Increase in rear-end collision risk by acute stress-induced fatigue in on-road truck driving.

2021

Increasing road crashes related to occupational drivers’ deteriorating health has become a social problem. To prevent road crashes, warnings and predictions of increased crash risk based on drivers’ conditions are important. However, in on-road driving, the relationship between drivers’ physiological condition and crash risk remains unclear due to difficulties in the simultaneous measurement of both. This study aimed to elucidate the relationship between drivers’ physiological condition assessed by autonomic nerve function (ANF) and an indicator of rear-end collision risk in on-road driving. Data from 20 male truck drivers (mean ± SD, 49.0±8.2 years; range, 35–63 years) were analyzed. Over …

Attention deficit hyperactivity disorder subtypes: Are there differences in academic problems?

1995

This article addresses the relationship between attention deficit hyperactivity disorder (ADHD) and academic problems. The development of diagnostic categories of attention deficits from the Diagnostic and Statistical Manual of Mental Disorders (3rd ed.) to the Diagnostic and Statistical Manual of Mental Disorders (4th ed.) is briefly reviewed. Forty‐five Chilean children demonstrating symptoms of either ADHD Combined Type, ADHD Predominantly Inattentive Type, or ADHD Predominantly Hyperactivity‐Impulsive Type are compared with each other and with a clinical control group on the prevalence of academic achievement problems. The data show that academic problems are more common among ADHD Comb…

Organizational and activational effects of testosterone in two populations with high androgenization susceptibility = Efectos organizadores y activad…

2013

Los esteroides sexuales como la testosterona (T) producen una organización y/o modificaciones relativamente permanentes de la estructura y función del sistema nervioso central. Una alta exposición prenatal a la T podría estar relacionada con una mayor sensibilidad a los efectos activadores de dicha hormona durante la edad adulta. Por otra parte, las fluctuaciones en los niveles endógenos de T pueden modificar transitoriamente las capacidades socio-cognitivas. Así, la conducta y los procesos cognitivos podrían ser el resultado de la interacción entre los efectos hormonales organizadores y activadores. La T podría ser considerada como un predictor de rasgos masculinizados tales como los rasgo…

ADHD and DAT1: Further evidence of paternal over-transmission of risk alleles and haplotype

2010

Contains fulltext : 87259.pdf (Publisher’s version ) (Closed access) We [Hawi et al. (2005); Am J Hum Genet 77:958-965] reported paternal over-transmission of risk alleles in some ADHD-associated genes. This was particularly clear in the case of the DAT1 3'-UTR VNTR. In the current investigation, we analyzed three new sample comprising of 1,248 ADHD nuclear families to examine the allelic over-transmission of DAT1 in ADHD. The IMAGE sample, the largest of the three-replication samples, provides strong support for a parent of origin effect for allele 6 and the 10 repeat allele (intron 8 and 3'-UTR VNTR, respectively) of DAT1. In addition, a similar pattern of over-transmission of paternal ri…

Project DyAdd: Non-linguistic Theories of Dyslexia Predict Intelligence

2020

Two themes have puzzled the research on developmental and learning disorders for decades. First, some of the risk and protective factors behind developmental challenges are suggested to be shared and some are suggested to be specific for a given condition. Second, language-based learning difficulties like dyslexia are suggested to result from or correlate with non-linguistic aspects of information processing as well. In the current study, we investigated how adults with developmental dyslexia or ADHD as well as healthy controls cluster across various dimensions designed to tap the prominent non-linguistic theories of dyslexia. Participants were 18–55-year-old adults with dyslexia (n = 36), …

Regulating the blink: Cognitive reappraisal modulates attention

2014

Our brain is unable to fully process all the sensory signals we encounter. Attention is the process that helps selecting input from all available information for detailed processing and it is largely influenced by the affective value of the stimuli. This study examined if attentional bias towards emotional stimuli can be modulated by cognitively changing their emotional value. Participants were presented with negative and neutral images from four different scene-categories depicting humans (‘Reading’, ‘Working’, ‘Crying’ and ’Violence’). Using cognitive reappraisal subjects decreased and increased the negativity of one negative (e.g., ‘Crying’) and one neutral (e.g., ‘Reading’) category res…
