Blood pressure increases while signing in a deaf population.

Recent technologic advances have permitted the observation of rapid and significant increases in blood pressure (BP) during verbal communication. The magnitude of the increase in BP is influenced by rate of speech, audience size, status, affective content, environmental setting, and resting BP. The current study evaluates the effect of communicating without vocalizing in 38 deaf adults. Similar to speaking individuals, deaf individuals exhibited significant increases in BP and heart rate (HR) while signing, and the magnitude of the increases were related to resting BP levels. These findings suggest that communication, independent of vocalization, has significant effects on the cardiovascular system. Further studies are needed to explore other dimensions of cardiovascular-communication relationships in deaf populations.

Conference report: functional magnetic resonance imaging for beginners--a review of the fMRI experience IV, 13-14 May 2002, Natcher Conference Center, National Institutes of Health, Bethesda, MD.

The fourth fMRI Experience meeting was held at the Bethesda, Maryland campus of the National Institutes of Health on May 13th and 14th, 2002. The purpose of the meeting was to provide a platform for students working with functional magnetic resonance imaging (fMRI) to pres ent their research to an international audience of peers. This year"s meeting featured special lectures from Dr. Leslie Ungerleider ("Imaging Mechanisms of Visual Attention") and Dr. Daniel Weinberger ("Genetic Variation and fMRI Response").

Acquisition and cross modal generalization of receptive and expressive signing skills in a retarded deaf girl.

A transfer of stimulus control procedure was used to teach a retarded deaf girl manual signing skills. Eight manual signs were trained in the receptive modality; eight others in the expressive modality. Acquisition of receptive and expressive signing skills occurred for most signs after they had been trained in multiple baseline order. There was a marked difference in cross modal generalisation between each of the trained signing modalities. With some exception training of receptive sign discrimination had little effect on the expressive usage of these signs. In contrast, training in the expressive usage resulted in a near perfect acquisition of receptive sign discrimination.

The effect of two procedures on spontaneous signing with Down's syndrome children.

In this study, two procedural aspects were investigated with regard to their effect on spontaneous use of manual signs with three Down's syndrome children. First, two modes of presenting reinforcement for spontaneous sign requesting were compared. Second, the effect of a least-to-most prompting procedure was evaluated. Within a randomization design, a statistically significant difference was observed between the two modes in favour of the one in which only a part of the sign-requested reinforcement was initially presented. Within a mixed design of reversal and multiple baseline, introduction of the least-to-most prompting procedure resulted in an increase of the spontaneous use of the target signs, while withdrawal of the procedure resulted in a decrease.

Free recall of lists of word and sign labels by severely handicapped children.

Two experiments are reported which tested short-term recall of lists of four sign or four word labels by severely handicapped children. The findings suggest that the subjects were more efficient at processing words than signs in short-term memory, and that their organization of sign and word lists were affected by the length of time the material had to be held in short-term store. Both of these effects were influenced by whether or not the subjects had to use the stimuli as labels when making a response.

Restraint fading and the development of alternative behaviour in the treatment of self-restraint and self-injury.

Restraint fading and differential reinforcement were used to reduce the self-injurious behaviour (SIB) and self-restraint of a profoundly retarded man. The variables maintaining both behaviours could not be identified via pre-treatment functional analysis; however, self-restraint exerted at least some stimulus control over SIB. In Phase 1, the subject's topography of self-restraint (wrapping arms in shirt) was replaced with another topography (wrapping wrists in towel) that could be more easily faded to a headband. However, the subject's restraints could not be completely faded, and any movement was accompanied by SIB; thus, in Phase 2, a compliance training procedure was implemented to reduce his SIB while increasing time out of restraint. In Phase 3, the subject was taught to mand for edibles during training sessions. Results indicated that restraint fading combined with the development of alternative behaviour could be an effective treatment procedure for those who engage in both self-restraint and SIB.

A stimulus control procedure to increase requesting with individuals who are severely/profoundly intellectually disabled.

Various procedures have been used to establish and increase manual signed and spoken requesting with individuals who are intellectually disabled. A few studies have used the so-called blockable response conditioned establishing operation (BR-CEO) as a stimulus control procedure to increase requesting. A variation on the BR-CEO is the interrupted chain procedure, in which requesting for the activity that had been interrupted is reinforced by continuation of the activity. Rather than interrupting an ongoing activity, six individuals who are severely/profoundly intellectually disabled were studied with respect to the differential effectiveness of presenting them incomplete versus complete referents (i.e. activity and objects) as a consequence of their requesting on their rate of requesting. Data were collected within a reversal design. The results show that five out of six individuals more than doubled their rate of requesting. Incomplete presentation of referents may be a practical procedure to increase requesting.
