Time pressure in acquisition negotiations: Its determinants and effects on parties’ negotiation behaviour choice

2008

Abstract Although negotiation literature suggests that time pressure influences negotiation behaviour, and in strategy literature, time appears as a key factor in acquisition formation, its impact on negotiation behaviour choice has not been the subject of a great deal of in-depth research. This paper focuses on the determinants of the amount of time pressure perceived by negotiation parties during acquisition negotiations and the impact on communication. The effect of cultural differences in both relationships is also analysed. The theoretical model proposed is explored by examining three acquisition negotiation cases involving Spanish firms. The evidence suggests that, contrary to expecta…

The effect of choice complexity on perception of time spent choosing: When choice takes longer but feels shorter

2009

Two studies examine the effect of the complexity of the choice environment on the perceived duration of the time spent choosing. The experiments demonstrate that the estimation of the time spent making a decision is affected by the number of options available in the choice set. In Experiment 1, participants having to choose 1 of 24 mobile phones tended to underestimate the time spent whereas participants confronted with the choice of 6 mobile phones tended to overestimate the actual time spent. Experiment 2 corroborates this finding, in the presence of varying degrees of attribute correlation. We conclude with theoretical and practical implications for marketers. © 2009 Wiley Periodicals, I…

Autocorrelation in meter induction: the role of accent structure.

2006

The performance of autocorrelation-based meter induction was tested with two large collections of folk melodies, consisting of approximately 13 000 melodies for which the correct meters were available. The performance was measured by the proportion of melodies whose meter was correctly classified by a discriminant function. Furthermore, it was examined whether including different melodic accent types would improve the classification performance. By determining the components of the autocorrelation functions that were significant in the classification it was found that periodicity in note onset locations was the most important cue for the determination of meter. Of the melodic accents includ…

T-pattern analysis for the study of temporal structure of animal and human behavior : a comprehensive review

2014

A basic tenet in the realm of modern behavioral sciences is that behavior consists of patterns in time. For this reason, investigations of behavior deal with sequences that are not easily perceivable by the unaided observer. This problem calls for improved means of detection, data handling and analysis. This review focuses on the analysis of the temporal structure of behavior carried out by means of a multivariate approach known as T-pattern analysis. Using this technique, recurring sequences of behavioral events, usually hard to detect, can be unveiled and carefully described. T-pattern analysis has been successfully applied in the study of various aspects of human or animal behavior such …

Musicians--same or different?

2009

In the neuroscience of music, musicians have traditionally been treated as a unified group, as if the demands set by their musical activities would be more or less equal in terms of perceptual, cognitive, and motor functions. However, obviously, their musical preferences differentiate them to a higher degree, for instance, in terms of the instrument they choose and the music genre they are mostly engaged with as well as their practicing style. This diversity in musicians' profiles has been recently taken into account in several empirical endeavors. The present contribution will review the evidence available about the various neurocognitive profiles these different kinds of musicians display.

Neuropharmacology of vision in goldfish: A review

2009

AbstractThe goldfish is one of the few animals exceptionally well analyzed in behavioral experiments and also in electrophysiological and neuroanatomical investigations of the retina. To get insight into the functional organization of the retina we studied color vision, motion detection and temporal resolution before and after intra-ocular injection of neuropharmaca with known effects on retinal neurons. Bicuculline, strychnine, curare, atropine, and dopamine D1- and D2-receptor antagonists were used. The results reviewed here indicate separate and parallel processing of L-cone contribution to different visual functions, and the influence of several neurotransmitters (dopamine, acetylcholin…

Neural networks engaged in milliseconds and seconds time processing: evidence from transcranial magnetic stimulation and patients with cortical or su…

2009

Here, we review recent transcranial magnetic stimulation studies and investigations in patients with neurological disease such as Parkinson's disease and stroke, showing that the neural processing of time requires the activity of wide range-distributed brain networks. The neural activity of the cerebellum seems most crucial when subjects are required to quickly estimate the passage of brief intervals, and when time is computed in relation to precise salient events. Conversely, the circuits involving the striatum and the substantia nigra projecting to the prefrontal cortex (PFC) are mostly implicated in supra-second time intervals and when time is processed in conjunction with other cognitiv…

Behavioral and physiological bases of relaxing and stimulating effects of odors and music

2021

This doctoral thesis examines the psychological and physiological mechanisms as well as the factors involved in the relaxing and stimulating effect (emotional activation) of pleasant odors, building on research work from the music domain. In Studies 1a and 1b, we observed that the modulation of the activation induced by odors influenced temporal information processing by speeding-up or slowing-down the rate of the internal clock pacemaker, similarly to what was previously reported using musicalstimuli. Moreover, prior verbalsuggestion attributing incongruent activation properties to the odors eliminated these effects, highlighting the importance of a priori expectancies on olfactory-induced…

T cell-independent joint destruction

1998

Rheumatoid Arthritis (RA) is a chronic systemic disorder of unknown etiology. Although, early and late stages of the disease may be driven by different processes, affected joints are characterized by inflammation, synovial hyperplasia, and abnormal immune responses [1]. The abundance of T cells within the rheumatoid synovium as well as the association of certain major histocompatibility complex (MHC) class II molecules with RA [2] implied a central role for T cells in the pathophysiology of the disease. However, recent advances in molecular biology have fostered new concepts for the pathogenesis of RA. Specifically, the investigation of early stages of disease, the development of novel anim…
