Neural mechanisms of attention become more specialised during infancy: Insights from combined eye tracking and EEG
No full textThe Fixation Shift Paradigm (FSP) measures infants' ability to shift gaze from a central fixation stimulus to a peripheral target (e.g. Hood & Atkinson, 1993: Infant Behavior and Development, 16(4), 405-422). Cortical maturation has been suggested as crucial for the developing ability to shift attention. This study investigated the development of neural mechanisms by combining EEG with simultaneous eye tracking during FSP testing, in typically developing infants aged between 1 and 8 months. The most prominent neural response was a frontal positivity which occurred only in the hemisphere contralateral to the target in the youngest infants but became more ipsilateral with age. This changing lateralisation was associated with improving ability to shift attention (decreasing saccade latencies and fewer 'sticky fixations'-failures to disengage attention from the central target). These findings suggest that the lateralisation of neural responses develops during infancy, possibly due to developing intracortical connections, allowing infants to shift attention more efficiently.DAAD; Leverhulme Trus
Where Oliver Fits by C. Atkinson
No full textAtkinson, Cale. Where Oliver Fits. Toronto, Tundra Books, 2017.
Oliver is a unique little puzzle piece with a cute round head smattered with blue and orange. He wants to be part of a bigger picture and goes on a journey to find where he fits. As he finds different puzzles, he discovers that the other puzzle pieces are not like him at all. Some puzzle pieces complain that he does not have enough of the right colour to fit properly. Others say that he is not the right shape. Determined to find his place in the world, he decides that he needed to be more like others in order to be accepted.
He uses creative strategies to change his shape and colour, however, after continuing to be rejected, he becomes desperate enough to create a disguise to finally fit into a puzzle. Although he finally finds his fit, Oliver begins to question whether or not it was right to pretend he was someone else and learns that it is better to be himself.
This is a wonderful story of imagination. Children learn through the eyes of Oliver that it is better to be one’s true self rather than changing to fit in. The illustrations are bright, colourful, and capture all the conflicting emotions that Oliver goes through. Designed for children ages 3-7, this book provides a good moral lesson in a fun and creative way.

The Extended Atkinson Family and Changes in the Expenditure Distribution: Spain 1973/74-2003
No full textThis paper emphasizes the properties of a family of inequality measures which extends the Atkinson indices and is axiomatically characterized by a multiplicative decomposition property where the withingroup component is a generalized weighted mean with weights summing exactly to 1. This family contains canonical forms of all aggregative inequality measures, each bounded above by 1, has a useful and intuitive geometric interpretation and provides an alternative dominance criterion for ordering distributions in terms of inequality. Taking the Spanish Household Budget Surveys (HBS) for 1973/74, 1980/81, and 1990/91 and the more recent Continuous HBS for 2003, we show the advantages and possibilities of this extended family in regard to completing and detailing information in studies of inequality focussing on the tails of the distribution and on the changes in the distribution when the population is partitioned into population subgroups.inequality measurement, Atkinson indices

Relation Between Event-Related Potential Latency and Saccade Latency in Overt Shifts of Attention
No full textNeural Differences between Covert and Overt Attention Studied using EEG with Simultaneous Remote Eye Tracking
No full textResearch on neural mechanisms of attention has generally instructed subjects to direct attention covertly while maintaining a fixed gaze. This study combined simultaneous eye tracking and electroencephalogram (EEG) to measure neural attention responses during exogenous cueing in overt attention shifts (with saccadic eye movements to a target) and compared these with covert attention shifts (responding manually while maintaining central fixation). EEG analysis of the period preceding the saccade latency showed similar occipital response amplitudes for overt and covert shifts, although response latencies differed. However, a frontal positivity was greater during covert attention shifts, possibly reflecting saccade inhibition to maintain fixation. The results show that combined EEG and eye tracking can be successfully used to study natural overt shifts of attention (applicable to non-verbal infants) and that requiring inhibition of saccades can lead to additional frontal responses. Such data can be used to refine current neural models of attention that have been mainly based on covert shifts.Open-Access-Publikationsfonds 201

Military Life at Fort Atkinson 1819-1827
No full textThis thesis uses an in depth examination of documents and other archeological finds in order to give an accurate description of military life at Fort Atkinson from 1819-1827.During the summer of 1956, the Nebraska State Historical Society Field Party, conducted by Marvin F. Kivett, Director of the Museum, excavated a portion of the site of the fort, near Fort Calhoun, Nebraska.The author was granted access to the material recovered by this archeological field party for the writing of this thesis.
The author first gives an examination of the background behind For Atkinson, including a description of the Yellowstone Expedition and the expedition for Council Bluffs.The author then goes on to discuss the construction of the fort, the general routines of those who lived at Fort Atkinson, the quartermaster and their duties, the medical department and even details of the musicians and band that worked at the fort.The author also wrote of the relations Fort Atkinson had with neighboring Indian tribes and finally discusses the reasons behind the decision to abandon Fort Atkinson and the overall significance of Fort Atkinson.
