Corpus callosum function in verbal dichotic listening: inferences from a longitudinal follow-up of Relapsing-Remitting Multiple Sclerosis patients.

2009

This study conducted a follow-up of 13 early-onset slightly disabled Relapsing-Remitting Multiple Sclerosis (RRMS) patients within an year, evaluating both CC area measurements in a midsagittal Magnetic Resonance (MR) image, and Dichotic Listening (DL) testing with stop consonant vowel (C-V) syllables. Patients showed a significant progressive loss of posterior CC areas (isthmus and splenium) related to increasing EDSS scores and an enhancing right ear advantage (REA) over time. A significant correlation between posterior CC areas and DL scores emerged in both evaluations, being negative for the right and positive for the left ear. The pattern of correlations suggests that the CC can serve …

The P600-as-P3 hypothesis revisited: single-trial analyses reveal that the late EEG positivity following linguistically deviant material is reaction …

2014

The P600, a late positive ERP component following linguistically deviant stimuli, is commonly seen as indexing structural, high-level processes, e.g. of linguistic (re)analysis. It has also been identified with the P3 (P600-as-P3 hypothesis), which is thought to reflect a systemic neuromodulator release facilitating behavioural shifts and is usually response time aligned. We investigated single-trial alignment of the P600 to response, a critical prediction of the P600-as-P3 hypothesis. Participants heard sentences containing morphosyntactic and semantic violations and responded via a button press. The elicited P600 was perfectly response aligned, while an N400 following semantic deviations …

G×E Interaction Influences Trajectories of Hand Grip Strength.

2016

Age-related decline in grip strength predicts later life disability, frailty, lower well-being and cognitive change. While grip strength is heritable, genetic influence on change in grip strength has been relatively ignored, with non-shared environmental influence identified as the primary contributor in a single longitudinal study. The extent to which gene-environment interplay, particularly gene-environment interactions, contributes to grip trajectories has yet to be examined. We considered longitudinal grip strength measurements in seven twin studies of aging in the Interplay of Genes and Environment across Multiple Studies consortium. Growth curve parameters were estimated for same-sex …

Greater university identification - but not greater contact - leads to more life satisfaction: evidence from a Spanish longitudinal study

2018

Background: A growing body of literature has highlighted the relationship between group identification (a subjective sense of belonging to one’s social group, coupled with a subjective sense of commonality with the group’s members) and wellbeing. However, little of this work is longitudinal, and few studies address reciprocal causality or control for intensity of contact with fellow group members.\ud \ud Method: We investigated the effect of university identification on satisfaction with life (SWL) over time (and vice versa) in 216 Spanish undergraduates, with seven months between T1 and T2. \ud Results: While greater university identification T1 predicted higher SWL T2, SWL T1 did not pred…

The associations of emotion regulation and dysregulation with the metabolic syndrome factor

2005

Abstract Objective Emotion regulation has been associated with good, and dysregulation with poor subjective health; but it is unclear if emotion regulation is related to metabolic syndrome. Methods Associations between the metabolic syndrome factor (systolic and diastolic blood pressure, waist circumference, high-density lipoprotein, triglycerides, and glucose), emotion regulation (the strategies of repair and maintenance, self-perceived emotion regulation) and dysregulation (emotional ambivalence); and subjective health (self-rated health and psychosomatic symptoms) were studied using a structural equation modelling (SEM) approach. The participants (96 women, 85 men) were drawn from the Jy…

Dark shadows of rumination: Finnish young adults' identity profiles, personal goals and concerns

2016

Young adults actively construct their identity by exploring and committing to opportunities through the setting of personal goals. Typically personal goal contents are related to young adults' developmental tasks but sometimes goals are self-focused. This longitudinal study explored personal goal and concern contents in relation to identity profiles among young Finns (N = 577) followed from age 23 to 25. Applying the Dimensions of Identity Development Scale, identity formation was measured at age 23. Latent Profile Analysis yielded five profiles: moderate achievement, moderate diffusion, achievement, diffused diffusion, and reconsidering achievement. Two “dark side” identity profiles, chara…

Has life satisfaction in Norway increased over a 20-year period? Exploring age and gender differences in a prospective longitudinal study, HUNT.

2017

Aim: The aim of the present study was to investigate the change in overall life satisfaction for different age groups and between genders over a 20-year period. Methods: Data from 1984 to 2008 were extracted from a large prospective longitudinal health study of Nord-Trøndelag (HUNT), Norway. The study included more than 176,000 participants ranging from 20 to 70+ years of age. Data were analysed using logistic regression and adjusted for gender. Results: The analyses revealed an increase in life satisfaction for all age groups from 1984–1986 (HUNT 1) to 1995–1997 (HUNT 2), with the highest levels being reached at 2006–2008 (HUNT 3). For all age groups, the data showed an increase of about …

Accommodative stimulus-response curves to low-pass filtered natural images

2018

To assess how the monocular steady-state accommodative stimulus-response curve is modified when viewing low-pass filtered natural images. Eighteen adult subjects participated in the study. The accommodative stimulus-response curve was objectively assessed by means of a Hartmann-Shack wavefront sensor. Measurements were taken at different accommodative demands. Target images were low-pass filtered versions of a natural image that were obtained applying different digital spatial filters that limited the spatial frequency content of the natural image. Cutoff spatial frequencies were set at 30, 21, and 15 cycles per degree (cy/deg). Mean data obtained for each target were fitted to linear model…

Reversibility in Chinese word formation influences target identification.

2011

We recorded event-related brain potentials during the processing of visually presented compound words in Mandarin Chinese. We capitalized on a particular characteristic of Chinese word formation, where two constituents can be combined in two different orders (A+B or B+A), yielding distinct meanings-so-called "reversible words". By investigating the impact of structural reversibility on the processing of compounds in Chinese during a lexical decision task, the present study revealed a pronounced difference between reversible and non-reversible words. Analyses revealed a more enhanced negativity (N400) for reversible words, reflecting demands during semantic processing, followed by a P300-lik…
