Lack of semantic parafoveal preview benefit in reading revisited
No full textIn contrast to earlier research, evidence for semantic preview benefit in reading has been reported by Hohenstein and Kliegl (Experimental Psychology: Learning, Memory, and Cognition, 40, 166–190, 2013) in an alphabetic writing system; they also implied that prior demonstrations of lack of a semantic preview benefit needed to be reexamined. In the present article, we report a rather direct replication of an experiment reported by Rayner, Balota, and Pollatsek (Canadian Journal of Psychology, 40, 473–483, 1986). Using the gaze-contingent boundary paradigm, subjects read sentences that contained a target word (razor), but different preview words were initially presented in the sentence. The preview was identical to the target word (i.e., razor), semantically related to the target word (i.e., blade), semantically unrelated to the target word (i.e., sweet), or a visually similar nonword (i.e., razar). When the reader’s eyes crossed an invisible boundary location just to the left of the target word location, the preview changed to the target word. Like Rayner et al. (Canadian Journal of Psychology, 40, 473–483, 1986), we found that fixations on the target word were significantly shorter in the identical condition than in the unrelated condition, which did not differ from the semantically related condition; when an orthographically similar preview had been initially present in the sentence, fixations were shorter than when a semantically unrelated preview had been present. Thus, the present experiment replicates the earlier data reported by Rayner et al. (Canadian Journal of Psychology, 40, 473–483, 1986), indicating evidence for an orthographic preview benefit but a lack of semantic preview benefit in reading English

The effect of high- and low-frequency previews and sentential fit on word skipping during reading
No full textIn a previous gaze-contingent boundary experiment, Angele and Rayner (2013) found that readers are likely to skip a word that appears to be the definite article the even when syntactic constraints do not allow for articles to occur in that position. In the present study, we investigated whether the word frequency of the preview of a 3-letter target word influences a reader’s decision to fixate or skip that word. We found that the word frequency rather than the felicitousness (syntactic fit) of the preview affected how often the upcoming word was skipped. These results indicate that visual information about the upcoming word trumps information from the sentence context when it comes to making a skipping decision. Skipping parafoveal instances of the therefore may simply be an extreme case of skipping high-frequency words
Verdazyl radicals as mediators in living radical polymerisation and dopamine end-functionalised polymers for application as friction modifiers
No full textVerdazyl Radicals as Mediators in Living Radical Polymerisation:
The aim of this work was to investigate verdazyl radicals as an alternative to
nitroxides as mediators in stable free radical polymerisation. Verdazyl radicals and
their unimolecular initiators were synthesised and utilised in the polymerisation of
styrene and n-butyl acrylate. Varying degrees of success was observed in the
polymerisations depending on the structure of the verdazyl radical. The
polymerisation of methyl methacrylate and the copolymerisation of styrene and
methyl methacrylate were also investigated. Correlations between observed
molecular weight and theoretical molecular weight were poor but may be improved
by optimisation of the reaction conditions. Electron paramagnetic resonance was
used to elucidate the radical structure as well as to confirm the living nature of the
polymerisation technique. Electron paramagnetic resonance was also utilised to
provide an insight into radical stability and reactivity in the various reactions
undertaken.
Dopamine End-Functionalised Polymers for Application as Friction
Modifiers:
The aim of this work was to synthesise oil soluble dopamine end-functionalised
polymers for mechanical testing to determine if the polymers can reduce friction by
film formation at a surface. A dopamine based initiator was synthesised and used in Cu(I) and Cu(0) mediated polymerisations with little success and the dopamine
catecholic end-group could not be identified as the polymer end-group. To enable a
successful living polymerisation, the catechol groups on dopamine required
protection. Complete deprotection of the catechol group can be achieved post
polymerisation. The polymerisation of lauryl methacrylate was achieved using a
polymerisation method designed for the long chain, non-polar molecule which
utilised Cu(I)Cl. The polymerisations were scaled up to obtain a baseline, protected
dopamine and deprotected dopamine polymers for mechanical testing. A reduction
in friction and wear observed for the deprotected dopamine polymer, however,
corrosion was also observed and may have affected the results

Eye movement sequences during simple versus complex information processing of scenes in autism spectrum disorder
No full textMinshew and Goldstein (1998) postulated that autism spectrum disorder (ASD) is a disorder of complex information processing. The current study was designed to investigate this hypothesis. Participants with and without ASD completed two scene perception tasks: a simple “spot the difference” task, where they had to say which one of a pair of pictures had a detail missing, and a complex “which one's weird” task, where they had to decide which one of a pair of pictures looks “weird”. Participants with ASD did not differ from TD participants in their ability to accurately identify the target picture in both tasks. However, analysis of the eye movement sequences showed that participants with ASD viewed scenes differently from normal controls exclusively for the complex task. This difference in eye movement patterns, and the method used to examine different patterns, adds to the knowledge base regarding eye movements and ASD. Our results are in accordance with Minshew and Goldstein's theory that complex, but not simple, information processing is impaired in ASD.<br/

Global analysis of night marine air temperature and its uncertainty since 1880: the HadNMAT2 Dataset
No full textAn updated version of the Met Office Hadley Centre’s monthly night marine air temperature dataset is presented. It is available on a 5? latitude-longitude grid from 1880 as anomalies relative to 1961-1990 calendar-monthly climatological average night marine air temperature (NMAT). Adjustments are made for changes in observation height; these depend on estimates of the stability of the near surface atmospheric boundary layer. In previous versions of the dataset, ad hoc adjustments were also made for three periods and regions where poor observational practice was prevalent. These adjustments are re-examined. Estimates of uncertainty are calculated for every grid box and result from: measurement errors; uncertainty in adjustments applied to the observations; uncertainty in the measurement height and under-sampling. The new dataset is a clear improvement over previous versions in terms of coverage because of the recent digitization of historical observations from ships' logbooks. However, the periods prior to about 1890 and around World War 2 remain particularly uncertain and sampling is still sparse in some regions in other periods. A further improvement is the availability of uncertainty estimates for every grid box and every month. Previous versions required adjustments that were dependent on contemporary measurements of sea surface temperature (SST); to avoid these, the new dataset starts in 1880 rather than 1856. Overall agreement with variations of SST is better for the updated dataset than for previous versions, maintaining existing estimates of global warming and increasing confidence in the global record of temperature variability and change

No full textThis report describes the mooring operations conducted during RV Ronald H. Brown cruiseRB0901 between 15 April and 5 May 2009.These mooring operations were completed as part of the United Kingdom Natural EnvironmentResearch Council (NERC) funded RAPID-WATCH Programme to monitor the AtlanticMeridional Overturning Circulation at 26.5°N. The primary purpose on this cruise for the UKteam was to service the RAPID Western Boundary moorings while the US team worked on theWestern Boundary Time Series project.Cruise RB0901 was from Charleston, South Carolina to Charleston, South Carolina andcovered the Western Boundary moorings deployed on cruises SJ08 and RB0701. This cruisewas the seventh annual refurbishment of the Western Boundary section of an array of mooringsdeployed across the Atlantic in order to continuously observe the Atlantic MeridionalOverturning Circulation (MOC). This array will be further refined and refurbished duringsubsequent years.The instruments deployed on the array consist of a variety of current meters, bottom pressurerecorders, and CTD loggers, which, combined with time series measurements of the FloridaChannel Current and wind stress estimates, will be used to determine the strength and structureof the MOC at 26.5°N.(http://www.noc.soton.ac.uk/rapid
