Self-generated stimuli have been found to elicit a reduced sensory response compared with externally-generated stimuli. However, much of the literature has not adequately controlled for differences in temporal predictability and control In two experiments, we N1 (and P2) components auditory-evoked potential self- tones that differed respect these factors. Experiment 1 (n = 42), increasing amplitude manner may often account observed reduction self-generated sounds. We also reducing over...

Abstract While volitional movement is thought to be initiated based on its anticipated capacity achieve sensory goals, stimulus-driven may generated with less regard for specific effects. Sensorimotor processes that make use of action-effect predictions therefore differ between these forms movement, including attenuation and the detection mispredicted motor In this study, we explored by comparing evoked response externally-generated tones those produced participants (n = 61), both according...

A 1 year study of the (4–1) and (5–2) hydroxyl bands in night airglow near μ has revealed a non-uniform rotational temperature across P branch each band. The increases with K′ value. There is pronounced seasonal variation showing summer minimum winter maximum. average measured brightness for band 4.6 kR (winter) 3.5 (summer), 5.8 4.3 (summer). It shown that time-averaged total intensity fluctuations during single are quite large, sometimes factor 2, not definitely correlated same period.

Ground based measurements of stratospheric NO 2 , using four different established methods on twilight sky observations in the spectral region 437.0–451.0 nm have been made at two locations: Primrose Lake (54.78°N, 110.05°W) and Priddis (50.86°N, 114.29°W), Alberta, Canada, during March April 1979. The differ from one another basis of: (a) whether or not ozone is taken into account, (b) a continuous absorption spectrum just few discrete wavelengths used for analysis, (c) assumed altitude...

A rocket-borne cooled (S-1) filter photometer was flown from Resolute Bay, Northwest Territories 75° N during geomagnetically quiet conditions. The derived altitude profile of the (6–2) hydroxyl band emission shows a peak at 95 km. An airglow background 2.7 R −1 or less 8380 is reported for altitudes above 125

Research into juror perceptions regarding the impact of intoxication on eyewitness memory and credibility is scarce for substances other than alcohol. However, jurors are frequently told to draw their personal beliefs experience with intoxicating infer case. It therefore important investigate laypeople's witness victim across a range substances, whether these associated substance familiarity. Participants (n = 470) completed survey assessing familiarity use different as well effects...

Ground based measurements of stratospheric nitrogen dioxide during morning and evening twilight have been made at Lauder, New Zealand, 169°40′E longitude 45°04′S latitude January February 1979. The analysis shows that ozone absorption overlying the bands cannot be ignored. After correcting for mean vertical column abundance was found to 2.9 × 10 15 cm −2 (evening, solar zenith angle = 90°) 1.1 (morning, 90°).

During the summer of 1968, observations were made auroral spectrum at 27 Å spectral resolution between 1.02 μ and 1.13 μ. Absolute brightnesses estimated from spectra for N 2 + Meinel (0–0) band, 1PG band D 0 – P (N I) line after subtraction background night airglow correcting atmospheric extinction. Simultaneous measurements 1NG O I 5577 have facilitated reduction infrared to equivalent international brightness coefficient III brightnesses.

Abstract Action-effect predictions are believed to facilitate movement based on its association with sensory objectives and suppress the neurophysiological response self- versus externally generated stimuli (i.e. attenuation). However, research is needed explore theorized differences in use of action-effect prediction whether uncued volitional) or external cues stimulus-driven). While much attenuation literature has examined effects involving auditory N1, evidence also conflicted regarding...

Noncoherent scattering of solar radiation, resulting in the filling-in Fraunhofer lines, has been observed day sky spectrum from 3855 to 4455 Å. The filling shows a continuous and almost constant effect over wavelength range covered, although there is tendency for magnitude decrease at shorter wavelengths. Observations taken different terrains times year show that tends be higher high ground albedo winter small zenith angles.
