As we were interested in naturalistic dog - and adult - directed speech,
the stimuli used in this experiment varied in both content and prosody.
For
the stimuli used in experiment 2, some dog content was repeated in ADS, and some adult content was removed in DDS.

My

Whereas animal studies have suggested that both cutaneous and proprioceptive percepts can be evoked
using this approach, the perceptual quality of the
stimuli can not be measured
in these
experiments.
The scientists
used the following arrangement for their
experiments: Over a period of ten minutes, 41 participants
in the study were given painful heat
stimuli to the hand which varied
in intensity throughout the duration of the
experiment.
To test this hypothesis, Roberts and colleagues
used an approach common
in psychophysics
experiments — estimating relative magnitudes — to gauge how people's moment - to - moment experiences vary when they view different types of
stimuli.
In this context, the use of live stimuli in laboratory experiments only permits minimal flexibility for controlling and dissecting specific behavioral response

In order to investigate further the alarm call system of the African elephant, we conducted a new series of
experiments with the same methodology, but
using a different threatening
stimulus, the voices of Samburu tribesmen.
In one
experiment we
used movies as a coarse proxy to examine dynamic formation of memories with rich
stimuli.
In particular pupils will be expected to respond to a
stimuli,
experimenting with the
use of symbolic and representational movements, explore differing types of travelling and transitional pathways with a Cyber theme along with performance skills within their set motifs.
As the same scripts were
used in both
experiments, this result also highlights that the preference shown
in experiment 1 could not be explained by the
use of specific words
in the content of the original
stimuli, such as «walk» or «dog», for example.
This supports the
use of these
stimuli and highlights that the null result found
in this
experiment is unlikely to be due to failures
in producing authentic DDS or ADS when the content is reversed.
Generalised linear mixed models (GLMMs) were
used to assess the effect of prosody (dog - directed / adult - directed); content (dog / adult) and content — prosody matching (matched (
experiment 1) / mismatched (
experiment 2)-RRB- on the acoustic measurements of
stimuli in experiments 1 and 2.
In a first
experiment, we
used the ventral caudate as a measure of intrinsic reward value and compared activation to conditioned
stimuli that predicted food, praise or nothing.
For the purpose of indexing intrusive memories of the
stimuli presented
in this
experiment, we
used selected items from the Intrusion subscale that directly pertained to the occurrence of unwanted memories of the target event (e.g «Pictures about it popped into mind»).
