The modifications occurring in the brain during learning and memory are still poorly understood but may involve long-lasting changes in synaptic transmission (synaptic plasticity). In perirhinal cortex, a lasting decrement in neuronal responsiveness is associated with visual familiarity discrimination, leading to the hypothesis that long-term depression(More)
Nicolson and Fawcett (Cognition 1990; 35: 159-182) have suggested that a deficit in the automatization of skill learning could account for the general impairments found in dyslexia. Much of the evidence for their claims has been collected via a dual task paradigm, which might allow for alternative explanations of the data. The present study examines(More)
Dyslexia is widely considered to be associated with impaired performance on phonological awareness tasks. However, it is likely that orthographic knowledge also influences performance on these tasks. In this study, adult dyslexics, for whom reading is no longer a major problem, were compared to a control group on a measure of articulatory awareness, a task(More)
Parkinson's disease (PD) can cause both motor speech and cognitive deficits, with those affected perceiving a negative effect on their everyday experiences of communication. One specific concern reported by people with PD is that people "talk over" them. Psychosocial reactions to communication changes in PD are highly individualized and do not correlate(More)
Marine protected areas (MPAs) are an important ecosystem-based management approach to help improve the sustainability of the spiny lobster fishery (Panulirus argus), but information is lacking concerning levels of lobster population connectivity among MPAs. Given their prolonged (~6 months) pelagic larval duration, population connectivity must be considered(More)
Evidence suggests that subliminal stimuli can influence ostensibly volitional, executive processes but it is unclear whether this is highly task-specific. To address this we used a set-switching task. Volunteers saw a word pair and reported either if both words had the same number of syllables or if both were concrete. Task selection was random and(More)
The white-spotted sandbass (Paralabrax albomaculatus) is a commercially important species in the Galapagos Marine Reserve, but is classified as endangered in the IUCN Red List. For this study, 10 microsatellite loci were isolated and characterized using Illumina paired-end sequencing. These loci can be used for genetic studies of population structure and(More)
Microsatellites are useful tools for ecologists and conservationist biologists, but are taxa-specific and traditionally expensive and time-consuming to develop. New methods using next-generation sequencing (NGS) have reduced these problems, but the plethora of software available for processing NGS data may cause confusion and difficulty for researchers new(More)
We test whether there is an own-age advantage in emotion recognition using prototypical younger child, older child and adult faces displaying emotional expressions. Prototypes were created by averaging photographs of individuals from 6 different age and sex categories (male 5-8 years, male 9-12 years, female 5-8 years, female 9-12 years, adult male and(More)
