“…The present study extended our previous findings about vertical tongue loading (Leung and Ciocca, 2004) to determine whether altered perception of tongue height affects during vowel production. The tongue-loading paradigm was originally developed by Grover and Craske (1991).…”

“…A headset incorporated with a padded nose bar, a chinrest, a pair of adjustable cheek pads, and a head-strap were used to keep the subject's head in position during the experiment (Leung and Ciocca, 2004). A 30-g weight was attached with a nylon thread to a plastic tongue holder (see Fig.…”

“…After completing the last trial of a loading direction, the subject exited the headset. Although the aftereffect of tongue loading only lasts about 75 s after the removal of the tongue holder (Grover and Craske, 1991;Leung and Ciocca, 2004), speakers took a break of at least 30 min before the beginning of the next block of trials to ensure that the aftereffect of loading did not affect the next block of trials. Each experimental session, including two loading directions and two masking conditions (with and without masking noise) took about 2 h to complete.…”

“…All speakers were naive about the aims of the experiment. Six out of nine speakers had taken part in a previous tongue loading study by Leung and Ciocca (2004); none of these speakers had any knowledge about the outcome of the previous tongue-loading study. Informed consent was obtained from the speakers prior to their participation in the study.…”

“…The tongue-loading paradigm was originally developed by Grover and Craske (1991). In this paradigm, a weight of 30 g is applied to a plastic tongue holder attached to speakers' tongues; a pulley system is then used to exert either a horizontal (left or right) or a vertical (upward or downward) loading force for 30 s. Tongue loading produces an aftereffect such that the judgment of the straight-ahead position of the tongue is typically shifted toward the direction opposite to the direction of loading, either along the horizontal axis (Grover and Craske, 1991) or the vertical axis (Leung and Ciocca, 2004). For example, after an upward tongue loading, speakers place their tongue at a lower position along the vertical axis than they did prior to tongue loading.…”

This study investigated the role of sensory feedback during the production of front vowels. A temporary aftereffect induced by tongue loading was employed to modify the somatosensory-based perception of tongue height. Following the removal of tongue loading, tongue height during vowel production was estimated by measuring the frequency of the first formant (F1) from the acoustic signal. In experiment 1, the production of front vowels following tongue loading was investigated either in the presence or absence of auditory feedback. With auditory feedback available, the tongue height of front vowels was not modified by the aftereffect of tongue loading. By contrast, speakers did not compensate for the aftereffect of tongue loading when they produced vowels in the absence of auditory feedback. In experiment 2, the characteristics of the masking noise were manipulated such that it masked energy either in the F1 region or in the region of the second and higher formants. The results showed that the adjustment of tongue height during the production of front vowels depended on information about F1 in the auditory feedback. These findings support the idea that speech goals include both auditory and somatosensory targets and that speakers are able to make use of information from both sensory modalities to maximize the accuracy of speech production.

We examined the involuntary isotonic muscle aftercontraction which follows a 1-min voluntary contraction at 60% of maximum voluntary force. Aftercontractions provide a unique paradigm for investigating the automatic postural control of the upper limb in man. Previous work has shown that the strength of these contractions in m. deltoid is linearly dependent on the inclination of the subject's body in the gravitational field. The current experiments were designed to test if this was due to the gravitational loading on the arm as this also changes with body inclination. The subject sat with the head stationary to prevent changes in vestibular orientation. Aftercontractions in m. deltoid were evoked with the normal weight of the arm present and also with arm loadings equal to 0, 25, 50 and 75% of this value. These reductions were produced by a counter lever apparatus. The results showed that the EMG amplitude of this involuntary contraction depended linearly on the loading of the arm. This is interpreted as being the result of positive load feedback. Aftercontraction EMG amplitude at 100% load was 2.7 times greater than at 0% load. The results are discussed in the context of recent work on positive load feedback in man and animals.

We investigated the impact of food deprivation on oral and manual haptic size perception of food and non-food objects. From relevant theories (need-proportional perception, motivated perception, frustrative nonreward, perceptual defence, and sensory sensitisation) at least four completely different competing predictions can be derived. Testing these predictions, we found across four experiments that participants estimated the length of both non-food and food objects to be larger when hungry than when satiated, which was true only for oral haptic perception, while manual haptic perception was not influenced by hunger state. Subjectively reported hunger correlated positively with estimated object size in oral, but not in manual, haptic perception. The impact of food deprivation on oral perception vanished after oral stimulations even for hungry individuals. These results favour a sensory sensitisation account maintaining that hunger itself does not alter oral perception but the accompanying lack of sensory stimulation of the oral mucosa. Both oral and manual haptic perception tended to underestimate actual object size. Finally, an enhancing effect of domain-target matching was found, ie food objects were perceived larger by oral than by manual haptics, while non-food objects were perceived larger by manual than by oral haptics.
