- In an event-related potentials (ERP) study, twenty-month-old children (n = 37) were presented with pseudowords to map to novel object referents in five presentations. Quicker attenuation of the visual Negative central component (Nc) to novel objects predicted a larger difference in N400 amplitude between congruous and incongruous presentations of pseudowords at test. Furthermore, better initial recognition of familiar objects (Nc difference between familiar and novel objects) predicted the strength of the N400 incongruity effect to the verbal labels of these real objects. This study presents novel evidence for a link between efficient visual processing of objects and word learning ability. © 2016 Kristina Borgström, Janne von Koss Torkildsen, and Magnus Lindgren.

Tidskriftsartikel (refereegranskat)abstract
- This study examined the predictive relations from symptoms of Attention-deficit/hyperactivity disorder (ADHD) and executive functioning (EF) to social and school functioning in 112 (62 girls) school children. High levels of teacher and parent ratings of ADHD symptoms at the ages of 8-8 1/2 years, and poor EF measured at the age of 8 1/2, were associated with poor social functioning measured by peer nominations and poor teacher ratings of school functioning at the age of 9 1/2. ADHD symptoms independently predicted social and school functioning, whereas EF independently predicted only school functioning. Interaction effects between ADHD and EF and between EF and gender were found: At high levels of symptoms of inattention, the poorer the EF, the greater the need for special education. At high levels of symptoms of hyperactivity/impulsivity, the poorer the EF, the higher the levels of physical aggression. Girls with poor EF were less accepted by peers than equivalent boys.

Developmental progression and side specialization in upper-limb movements from 4 to 8 years in children born preterm and fullterm
- 2018

Tidskriftsartikel (refereegranskat)abstract
- This study investigated developmental changes and differences in upper-limb movement organization from 4 to 8 years of age in children born preterm (PT) and fullterm (FT). Kinematic recordings of precision-demanding unimanual movements and lateral assessments were carried out in 37 children (18 PT). All children, particularly children born PT, displayed considerable gain in movement kinematics. Contrary to controls, children born PT displayed persistently less-evident side preference. Gestational age (GA) contributed significantly to kinematic differences shown, with larger upper-limb deviances in the lowest GAs, in agreement with cross-sectional findings of altered hemispheric connections and delayed side-specialization among children born very PT.

Independent contributions of cognitive functioning and social risk factors to symptoms of ADHD in two Nordic population-based cohorts

Tidskriftsartikel (refereegranskat)abstract
- This study examined independent contributions of executive functioning (EF), state regulation (SR), and social risk factors to symptom dimensions of attention deficit hyperactivity disorder (ADHD) in two cohorts, which included 221 Norwegian children and 294 Finnish adolescents. Independent contributions of EF and SR were shown in the Norwegian cohort and EF contributed independently in the Finnish cohort. When controlling for each symptom dimension, cognitive functioning and social risk factors were differentially associated with inattention and hyperactivity/impulsivity symptoms. The results show the need to include both social risk factors and cognitive functioning to obtain a better understanding of ADHD symptoms.

- The current review offers a unique introduction to the use of corneal reflection eye tracking in infancy research. We provide a detailed description of how to calibrate, collect, and analyze infants' gaze in a series of experimental paradigms, focusing specifically on the analysis of visual tracking, point of gaze, and the latency of gaze shifts (prediction and reactive gaze shifts). The article ends with a critical discussion about the pros and cons of corneal reflection eye tracking.

Cognitive Sex Differences Are Not Magnified as a Function of Age, Sex Hormones, or Puberty Development During Early Adolescence
- 2013

- Are cognitive sex differences magnified by individual differences in age, sex hormones, or puberty development? Cross-sectional samples of 12- to 14-year-old boys (n = 85) and girls (n = 102) completed tasks assessing episodic memory, face recognition, verbal fluency, and mental rotations. Blood estradiol, free testosterone, and self-rated puberty scores were obtained. Sex differences were found on all cognitive measures. However, the magnitude was not larger for older children, hormones and cognitive performance were not associated, and early maturers did not perform better than late maturers. Thus, cognitive sex differences were not associated with age, levels of sex hormones, or puberty development.

Neurocognitive test profiles of extremely low birth weight five-year-old children differ according to neuromotor status

- The neurocognitive outcome of children born with extremely low birth weight (ELBW) is highly variable due to the complexity of morbidity. So far, no study has compared comprehensive neuropsychological test profiles in groups with different neuromotor status. In a national cohort of ELBW children neuropsychological test profiles were assessed in 4 groups defined according to a neurological examination at 5 years of age: normal neuromotor status (N = 56). motor coordination problems (N = 32), Multiple Subtle neuromotor signs including, both motor coordination problems and deviant reflexes (N = 20), and spastic diplegia (N = 12). The neurocognitive assessment included a test of intelligence. the Wechsler Primary and Preschool Scale of Intelligence-Revised (WPPSI-R) and 14 subtests of attention and executive functions, verbal functions, Manual motor functions, visuoconstructional functions and verbal learning (NEPSY). The children with normal neuromotor status performed within the average range: children with motor coordination problems had widespread impairment and children with spastic diplegia and children with multiple minor neuromotor(Or Signs had uneven test profiles with stronger verbal results but weaknesses in attention and executive functions, and in manual motor and visuoconstructional tasks. In conclusion, very preterm children with neuromotor signs, including motor coordination problems, are at risk for neurocognitive impairment. in spite of average intelligence. More impaired children have more irregular test profiles. Follow-up and neuropsychological assessment of very preterm children with minor neuromotor signs are therefore indicated.
