Legria hf g10

A male speaker (MB) was recorded with a digital video camera (videos were framed as headshots) and its internal microphone (Canon Legria HF G10, 25 frames/s) while pronouncing /bi/ and /gi/. With FFmpeg, AV /bi/ and /gi/ video segments were extracted from the recordings, and sounds were extracted from the segments (and equated in maximum intensity). The first three and final two frames of the videos were faded in/out, and the videos were saved as bitmaps strings (30 bitmaps per video). AV stimulus presentations consisted of auditory /bi/ and /gi/ and a simultaneously presented /bi/ or /gi/ bitmap string (40 ms/bitmap, 520 ms of anticipatory motion before sound onset), resulting in two AV congruent stimuli (A_bV_b, A_gV_g), one fusion stimulus (A_bV_g) and one combination stimulus (A_gV_b). For V‐only presentations (V_b, V_g), the /bi/ and /gi/ bitmaps were delivered in silence, and for auditory‐only presentations (A_b, A_g), the bitmap string consisted of black images.

Forty adult A. amphalodes were collected at Amanzi in order to investigate the prey-capture behaviour of the spider. After transfer to the laboratory, adult spiders of both sexes were placed separately into an arena consisting of 250 ml plastic bottles (8 cm in diameter, 15 cm tall) containing a 3 cm layer of sand in the bottom. They were left for three days to settle down at room temperature (~25 °C) and a natural LD (12:12) regime, during which time they were starved. Spiders usually dug themselves into the sand immediately after being released into the arena. Hodotermes mossambicus termites from one nest were collected in a suburban grassland in Langenhoven Park, Bloemfontein and kept together in plastic containers (40 cm in diameter) filled with soil. Trials began when a termite was introduced to the arena occupied by a spider. The hunting sequence was observed and recorded using handycam Canon Legria HF G10. If the spider did not start hunting within one hour, the prey was removed. We measured the paralysis latency as the time between successful attack and termite immobilization. After the trial the whole body length of termites and prosoma length of the spider were measured with a Nikon SMZ800 stereomicroscope.

The conversations were recorded in a soundproof room at the Max Planck Institute for Psycholinguistics in Nijmegen, The Netherlands. Participants were seated facing each other at approximately 90 cm distance from the front edge of the seats (Figure 1).
Two video cameras (Canon XE405) were used to record frontal views of each participant, two cameras recorded each participant’s body from a 45 degree angle (Canon XF205 Camcorder), two cameras (Canon XF205 Camcorder) recorded each participant from a birds-eye view while mounted on a tripod, and finally one camera (Canon Legria HF G10) recorded the scene view, displaying both participant at the same time. All cameras were recorded at 25 fps. Audio was recorded using two directional microphones (Sennheiser me-64) for each participant (see the Appendix A for an overview of the set-up). Each recording session resulted in seven video files and two audio files, which were synchronised and exported as a single audio-video file for analysis in Adobe Premiere Pro CS6 (MPEG, 25 fps), resulting in a time resolution of approximately 40 ms, the duration of a single frame. For the coding of facial signals reported in the present study, only the face close-ups were used, one at a time for best visibility of detailed facial signals.
