Non-aversive reduction of cigarette smoking in two adult men in a residential setting.

Two middle-aged men with mental retardation, addicted to smoking cigarettes, operated spinners that determined the probability with which they could obtain cigarettes and other items. Absence of several maladaptive behaviors permitted the operation of the spinners hourly (i.e., DRO 60 min), 16 h per day, 7 days per week. The actual frequencies of obtaining cigarettes followed the theoretical probabilities of obtaining cigarettes in all phases of the study. Presumed smoking frequencies were reduced by about 50% with associated medical benefits. Low frequencies of maladaptive behaviors were maintained throughout.

Applications of SNMS in archaeometry.

The recently developed High Frequency Mode HFM of electron gas SNMS allows investigations on insulating samples with the well known advantages of the SNMS Direct Bombardment Mode DBM for the analysis of conducting samples. HFM has been applied to analyses of different historic ceramic and glass samples in order to demonstrate the possibilities of SNMS in this field. It is shown that manufacturing places of ceramic samples could be distinguished by SNMS mass spectra ("fingerprints"). Furthermore questions of the constituents of colour remains on a painted ceramic ("Kaisermedaillon") could be answered by our SNMS analyses. SNMS investigations have been also applied to corrosion phenomena on different glass samples.

Observation and measurement of drooling by people with mental retardation.

Four brief observational surveys were used to score residents of a state institution for people with mental retardation as drooling/not drooling. An average of 14% of the population was identified as drooling on the occasion of any of the surveys; the accumulated proportion of clients reported as drooling was 28%. In a second study, the drooling of 2 of the clients identified in the first study was sampled within and across days. These clients drooled different amounts both within and between days, which validated their presence and classifications in the first study.

Cyclical self-injurious behavior, contingent water mist treatment, and the possibility of rapid-cycling bipolar disorder.

Cyclical self-injurious behavior (SIB) in the form of self-slapping was treated in a 45-year-old, profoundly retarded woman who had a life-long history of SIB. Her SIB alternated between high (mean = 8.54 responses per min; SD = 6.77 and low (mean = 0.05 responses per min; SD = 0.20) frequencies every 8 weeks on average. Instances of self-slapping produced water mist treatment paired with a verbal command, "No hitting". Absence of self-slapping and/or completion of a work task led to a variety of outcomes, including brief back rubs, sips of water, small edibles, and praise. Water mist treatment reduced the frequency of SIB within treatment days during high frequency periods, but produced no reduction across treatment days. Treatment onset was associated with a slight increase in the frequency of SIB during three of the five low frequency periods. However, water mist treatment suppressed SIB completely in sessions during low frequency periods and the suppression continued across treatment days. Water mist treatment produced no discernible changes in the length of the high and low frequency periods of SIB.

The use of contingent water misting in the treatment of self-choking.

A 25-year-old, deaf-blind, mentally retarded male was treated for chronic self-choking using water mist treatment and positive reinforcement. During pre-treatment baseline, self-chokes occurred at a rate of 2.09 per minute. During treatment sessions each self-choke was followed by water misting of the subject's face paired with a forceful "No!". Periods of 20 sec absent of self-chokes were positively reinforced with liquids and/or social contacts. Treatment procedures were generalized from the initial therapists, location, and absence of other clients and staff to other locations, and the presence of other clients and staff. Water mist treatment was associated with at least a 10-fold and as much as a 100-fold reduction of self-choking (i.e. to 0.02-0.20 self-chokes per min) across treatment and generalization phases. Eight-month follow-up observations showed that self-choke rates were at zero.

Family co-operation programme description.

Current parenting practices indicate a continuing trend towards less family interaction. Institutional attempts to intervene with parents often fail. The 'Family Co-operation Programme' provides a tangible method for families and schools to work together in preventing alcohol and drug abuse, by utilising the positive influence of the home and strengthening family relationships. The Board of Education for the State of Utah has tested and is currently implementing a unique, low-cost, alternative to impact on the home. Utilising a K-12 alcohol/drug abuse school-based curriculum, the child, based on his/her inclass training, becomes the resource for family co-operation activities. These include training in coping skills, decision-making, resistance to peer persuasion, increased self-esteem and alcohol/drug information. Grade level materials go home with the child, who returns a requested parent evaluation. Data for over one thousand families show the positive impact of the activities.
