Sexes could be discriminated in terms of their personality profiles—females being less toughminded than males and tending to be more emotional. None of the state factors were shown to be different between sexes. Factorial analysis revealed that the 15 state scales were intimately interrelated: the first two factors extracted resembled fairly closely, E and N. Canonical analysis showed that personality traits are good predictors of emotional state. Discrimination analysis demonstrated that stables and unstables were clearly distinguishable in terms of state profile (exhibiting 12 significant differences along the 15 state scales). 相似文献

Effects of environmental variables on performance may be mediated by individual stress states. In this study the effects of jet-aircraft engine noise and signal salience on vigilance performance and self-reported stress state were examined. One hundred and ninety-two (96 female and 96 male) participants were randomly assigned to four experimental conditions consisting of 48 participants each resulting from the factorial combination of signal salience (high and low salience signals) and noise (95 dBA intermittent aircraft noise or quiet). Performance metrics and self-reported stress state (Task Engagement, Distress, and Worry) were collected. Performance in the noise conditions was significantly better than in the quiet conditions. Performance in the high salience conditions was significantly better than the low salience conditions. Noise elevated Task Engagement and low signal salience elevated Distress. Moreover, structural equation model analyses were used to examine stress state mediation between the experimental variables and performance. These analyses indicated Engagement mediates between noise and vigilance performance. 相似文献

Observations made during two partial eclipses of the Sun show that the Mach bands on shadows cast by the Sun disappear and reappear asymmetrically as an eclipse progresses. These changes can be explained as due to changes in the shape of the penumbras of shadows as the visible portion of the Sun forms crescents of different orientation. 相似文献

Although Ernst Mach is widely recognized in psychology for his discovery of the effects of lateral inhibition in the retina ("Mach Bands"), his contributions to the theory of depth perception are not as well known. Mach proposed that steady luminance gradients triggered sensations of depth. He also expanded on Ewald Hering's hypothesis of "monocular depth sensations," arguing that they were subject to the same principle of lateral inhibition as light sensations were. Even after Hermann von Helmholtz's attack on Hering in 1866, Mach continued to develop theories involving the monocular depth sensations, proposing an explanation of perspective drawings in which the mutually inhibiting depth sensations scaled to a mean depth. Mach also contemplated a theory of stereopsis in which monocular depth perception played the primary role. 相似文献

The present paper studies a specific way of addressing the question whether the laws involving the basic constituents of nature
are statistical. While most German physicists, above all Planck, treated the issues of determinism and causality within a
Kantian framework, the tradition which I call Vienna Indeterminism began from Mach’s reinterpretation of causality as functional
dependence. This severed the bond between causality and realism because one could no longer avail oneself of a priori categories
as a criterion for empirical reality. Hence, an independent reality criterion had to be sought, a problem which all three
physicists to be studied solved in different ways that were mainly conditioned by their different concepts of probability.
In order to prevent a dissipation of intuited facts, Mach had to resort to a principle of unique determination as his reality
criterion, especially when discussing the Principle of Least Action. Giving theories more independence, Boltzmann understood
atomism as property reduction to precisely defined theoretical entities and their interactions. While this served as a relative
reality criterion, he also advocated a constructivist one because atomism was already implied by our finitary reasoning power.
Finally, Exner contemplated the idea that all apparently deterministic laws are only a macroscopic limit of an irreducible
indeterminism, because by adopting the frequency interpretation, observable collectives could be considered as the real basic
entities.
