Normal blinking prevents dry eyes and helps the patient to relax and concentrate during examination. With Octopus Blink Control, you need never worry again about missing a stimulus presented in static perimetry. Stimuli interrupted by the patient’s blinking are automatically repeated later during the test. Given that stimuli moving toward individuals generally capture attention (e.g., Lin, Franconeri, & Enns, ), and that static images of African American males have already been shown to spontaneously capture attention to the extent that people associate Blacks with threat (Trawalter et al., ), Whites who feel anx-.

We calculated the responses to static and moving faces and objects in a group analysis (Fig. 2 a) and identified the separate contributions of the factors: shape category (face vs object), motion (moving vs static), and their interaction (Fig. 2 b) in a two-way ANOVA. With regard to the effect of visual information in audiovisual spatiotemporal interactions, some studies have reported that visual stimuli changed the percept of a static sound as moving .

Subitization and attentional engagement by transient stimuli. Alston L(1), Humphreys GW. Author information: (1)Centre for Cognition and Neuroimaging, Department of Human Sciences, Brunel University, Uxbridge, UK.
A series of experiments investigated the visual selection of moving and static items during by: The data suggest that the processes supporting subitization are highly sensitive to dynamic stimuli and depend on the ease of segmentation between static and moving arrays. Do you want to read the.
In support of this, subitization of static items improved as the movement speed of the distracters increased.
The data suggest that the processes supporting subitization are highly sensitive to dynamic stimuli and depend on the ease of segmentation between static and moving by: The general formula for the Gabor stimuli was as follows: L (x, y) = L m [1 + sin (2 π xf s + ϕ)] × exp [-(x 2 + y 2) / (2 σ 2)] Dynamic stimuli were identical to static stimuli in every respect except that the sine wave function was temporally modulated, creating an associated translation of the grating within the Gaussian by: Timing studies have reported a lengthening of the perceived time for moving as opposed to static stimuli and for stimuli of higher as compared to lower amounts of implied : Jennifer Freyd.
The different sensitivities of these two types of channels are held to Subitization of moving and static stimuli book responsible for the difference between the CSF obtained with static stimuli and that obtained with temporally modulated or moving patterns (Robson, ): in particular, the sensitivity of the transient channels reduces or abolishes the low spatial-fre- quency cut in the.
Subitizing is studied using habituation and familiarization, visual expectation and enumeration paradigms. In the habituation paradigm changes in viewing time are considered a measure of habituation to repeated presentations and dishabituation to novel stimuli.

A number of psychophysical studies have shown that moving stimuli appear to last longer than static stimuli. Here, we report that the perceived duration for slow moving stimuli can be shorter than for static stimuli under specific circumstances.
Observers were tested using natural movies presented at various speeds (× = static, × = slow, or × = fast, relative to original speed. Static stimuli implying motion (e.g., an image of a hand dropping a mug) have been found not only to lead to RM effects (Freyd ; Freyd et al.
) but also to significantly increase metabolic. First, the authors replicated earlier findings. Subjects adapted to two moving gratings placed on either side of fixation, and brain activity was measured with functional MRI (fMRI) in a delayed test phase when two static gratings were ty in V5/MT was elevated when an MAE was perceived (after adaptation to unidirectional motion), compared to a control condition when no MAE.
Moreover, V1–TMS induced a temporally unspecific interference with visual processing as it impaired the processing of both motion and static stimuli at the same delays. These results are in accordance with fast moving stimuli reaching V5 through a different route than slow moving stimuli.

Static stimuli were then created from a screenshot of the final frame of each expression and speech. Seventy additional participants from the psychology undergraduate student population were recruited to rate both the video stimuli and their static exemplars to ensure that these stimuli depicted recognizable emotional expressions.
Participants then view a similar test stimulus: the stripes are either stationary, moving downward, or moving upward. Participants are asked to report whether the stripes are moving.
When participants respond that the stripes are moving, they are additionally asked to report the direction of motion. In the Static condition, movies were generated by replicating the last frame from each corresponding Dynamic movie 30 times (Figure 2).In the Shuffled condition, a set of 10 different random frame permutations was generated and these orders were applied to each of the Dynamic movies, producing a total of temporally shuffled movies (see the “Ideal observer” section below for more.
We are running a visual discrimination study in the peripheral vision of patients with partial cortical blindness that uses moving and static visual stimuli (real motion) in different orientations. The aperture problem is the fact that when a moving object is viewed through an aperture (or a receptive field), the direction of motion of a local feature or part of the object may be ambiguous.
The solution to this problem is to have another set of neurons listen to the V1 neurons and integrate the potentially conflicting signals. A group of stimuli that share specified common elements along formal, temporal, and/or functional dimensions.
