TL;DR: Evidence is provided that the interaction between hemispheres is of particular importance in the early phase of command integration during acquisition of a novel bimanual task and it is proposed that the dynamic changes in interhemispheric interaction reflect the establishment of efficient bimanUAL 'motor routines'.

TL;DR: In this article, the Category (C)-Ratio (R) (CR) scaling methodology is presented together with a new CR scale: the CR100 scale, and it is shown that CR100 could make the predicted differentiation between sexes, whereas AME could not.

TL;DR: The correspondence of identified neuronal processes with functions of abstract models encourages the development of realistic computational models that can predict bimanual behavior on the basis of neuronal activity.

TL;DR: The efficacy of concurrently moving both arms, with and without a load added to the uninvolved arm, in facilitating the quality of movement of the involved side in individuals with moderate, chronic hemiplegia is addressed.

TL;DR: It was found that a to-be-executed response B was in general initiated more quickly when it resulted in the same effect as a concurrently prepared response A.

TL;DR: Parallel perceptual processing of target and flankers, followed by competition of responses to the target and to the incongruent flankers are suggested, suggesting that target selection may proceed during the saccade from SL to SR.

TL;DR: Results suggest that both stability and adaptability of coordination are reduced in prosthetic walkers but may be enhanced by training them to walk at higher velocities.

TL;DR: The results suggest that when learning bimanual coordination patterns, older adults are more sensitive to the structure of the practice conditions, particularly the availability of concurrent visual information.

TL;DR: Findings showed that central cost and pattern stability covary, suggesting that bimanual coordination and the attentional activity of the CNS involved in maintaining such a coordination bear on the same underlying dynamics.

TL;DR: In two experiments it is shown that the intention to produce a spatial consequence in the environment to an otherwise spatially neutral stimulus leads to a shorter response, if the responses and the intended consequences share relative positions compared to a situation where this is not the case.

TL;DR: This study examined states of awareness with the Remember/Know paradigm during verbal recognition memory in young and old adults to offer further support for the distinction between remembering and knowing and for the processing-resources hypothesis of aging.

TL;DR: A number of experiments have shown that the magnitude of the associative priming effect increases substantially when there is a high proportion of associatively related pairs in the list when the stimulus-onset asynchrony (SOA) between prime and target is long, but in the present series of experiments this effect is manipulated when the SOA was very brief.

TL;DR: Observations indicate that the upper limit for TI is a stable feature across the different age groups and an age-related modulation within the temporal window of the operating TI seems to be linked to cognitive development.

TL;DR: The questions to be answered are the following: Does the haptic perception of parallelity in the midsagittal plane also show systematic deviations from veridicality?

TL;DR: The findings indicate that when a word (animal name) is presented, its meaning is accessed automatically and part of this meaning relates to the size of the animal in real life.

TL;DR: In four experiments it is shown that even as many as 12 primes do not cause long-term semantic priming in visual word recognition, which is consistent with a number of other results showing that semantic information plays a minimal role in long- term priming.

TL;DR: It was taken to suggest that reduced readiness gives rise to more forceful responses that are then more difficult to inhibit.

TL;DR: The results indicate that an endogenous shift of attention precedes endogenous saccades, providing further support for theories of visual selection that assume a tight coupling between attention and saccade.

TL;DR: It was concluded that conversion paralysis is associated with a specific impairment in the explicit initiation of processes with a spatial and motor component.

TL;DR: The results show that spatial selection is impaired in peripheral vision, and that this is one important factor underlying lateral masking effects.

TL;DR: Time pressure increased the LRP amplitude during response preparation which is consistent with the view that response strategies generally influence movement preparation on a motoric level.

TL;DR: Evidence for the role of knowledge of results (KR) in the estimation of medium time intervals (4-12 s durations) is presented and the findings taken together converge on the interpretation that KR affects the reference memory (RM), rather than the other components of the model.

TL;DR: A historical note is provided on the evolution of the behavioral study of interlimb coordination and the reasons for its success as a field of investigation in the past decades and the main theme is centered on the brain basis of inter Limb coordination.

TL;DR: It is concluded that coupling may enhance the performance of the impaired arm in children with spastic hemiparesis, but only during symmetric bimanual coordination.

TL;DR: It is speculated that there may be a closed object advantage for detecting a difference in polarity which interferes with the task of detecting a regularity in shape, and evidence from the analysis of foil rejection trials supports such a speculation.

TL;DR: The characteristic profile of shift costs disappeared when long precue intervals (PCIs) were used, and this finding suggests that both switching and implementation operations are endogenously controlled.

TL;DR: In this paper, two transformationally related patterns forming rotation/reflection equivalence sets of different size's are presented, and two successively presented patterns are judged as same when they belonged to the same equivalence set and different otherwise.

TL;DR: Evidence is presented that advance information reducing the number of stimulus-response alternatives in a choice reaction time (RT) task can shorten the very latest motoric stages of RT.

TL;DR: Data analysis showed that matching of facial stimuli was faster, more accurate and more consistent under upright than under inverted orientations for all stimulus categories; mostly for full faces, and least for internal features.

TL;DR: Two experiments indicate that prospective judgments of a temporal target are influenced by nontarget temporal features, and show that the duration of an irrelevant cue can influence judgment of the target interval, as if it were also timed without appropriate control.
