Yet ignoring the displacement effects is exactly what Paul Krugman and Dean Baker have done in their praise of recent studies that use "cross-state variation in stimulus spending per capita to estimate the employment effects of the stimulus," studies comparing states that received more stimulus to states that received less.
Electrical stimulus studies have been used to examine what causes the chromatophore to expand, but little is known about how chromatophores actually behave in intact squid, especially during chromatic pattern expression.
In pre/post stimulus studies in which the transcriptional response is monitored at one specific time instant after a prolonged insulin exposure, genes showing a transient response followed by a return to the pre-stimulus expression or a systematic, but small in magnitude, change in the expression, are likely to be missed [11].
Along with the oncogenic stimulus, studies have demonstrated that the cell of origin also can dictate pathological features observed in tumours.
Instead of using a single exercise stimulus, studies from our laboratory detected the accumulative effects of intensive exercise on hepcidin expression by having the rats take strenuous treadmill running for 5 weeks.
Increases in progesterone during the luteal phase were associated with increased accuracy in decoding facial expressions (Study 1) and increased attention to social stimuli (Study 2).
We empirically integrate these principles to gauge their unique contribution to the aesthetic experience, using two distinct surveys (study 1 300 respondents and 20 stimuli, study 2 60 respondents and 24 stimuli).
Study 1 establishes effects by employing psychometric measures and abstract stimuli; study 2 corroborates findings with another product category and realistic stimuli; and study 3 complements psychometric measures with eye tracking data to demonstrate that visually more complex contexts divert viewer attention, hereby lowering processing fluency and target attractiveness.
Besides the scientific stimuli, studying human dispersal across the continent brings some academic pleasures.
In conclusion, the man-made stimuli studied, which were presumably produced to evoke pleasant and/or enjoyable visual perception in human observers, form a subset of all images and share statistical properties in their Fourier power spectra.
