We consider the duration of face orientation towards the robot from the first observation time to time τ as (f_{_{textit {robot}}}^{tau }), and the duration of the face orientation to others as (f_{_{textit {other}}}^{tau }).
Conversely, given the large drop in audibility associated with off-axis listening in directional mode, we expected to observe dramatic changes in the complexity and duration of head orientation movements with listeners using the directional mode.
This study investigated the effects of exposure duration and orientation of an ignored prime on subsequent naming of an upright object, in order to test whether the early stages of object processing (i.e., prior to encoding and consolidation in VSTM) are sensitive to the image-plane orientation of the object.
The duration of overlapping face orientation between humans is directly related to how much humans were going to approach each other.
(2) The duration of long-range orientation flights declined from the first to the fourth flight because the bees spent less time inspecting the immediate surroundings of the hive.
A description of behavioural measures is given in Table 3.> To test whether bark origin would have an effect on the strength of response, we used a general linear mixed model (GLMM) with Gaussian error structure to assess differences in the duration of subjects' first orientation towards the playback speaker, and a GLMM with Poisson error structure to assess differences in initial displacement.
And, if not, determining whether contrast adaptation, a relatively slow phenomenon compared to fixation duration, contributes to contrast-invariance of orientation tuning.
Videos were subsequently imported into Adobe Premiere Pro CS4 with a time resolution of 25 frames/s, and frame-by-frame analysis of videos was used to score the duration of the subject's first orientation towards the speaker, defined as an orientation within 45° of the direction indicated in the film footage.
Radar and satellite telemetry have been used to analyse the orientation and duration of long migrating flights (Casement 1966; Butler et al. 1998; Hays et al. 2001), but none provided detailed information about flights of shorter duration.
The duration of the subject's first orientation towards the speaker was significantly longer in response to unknown conspecific calls than to known conspecific calls, strongly suggesting that adult male vervets differentiate between the calls of known and unknown males and are more attentive to the presence of "strangers".
