PROVIDING A LESS RESTRICTIVE ENVIRONMENT FOR PROFOUNDLY RETARDED PERSONS BY TEACHING INDEPENDENT WALKING SKILLS

A basic right of all handicapped persons is to live in the least restrictive environment possible. In this investigation, procedures were evaluated for teaching four institutionalized males with profound retardation necessary skills to increase their individual freedom of movement. Following baseline, a travel training program with a backward chaining format was implemented to teach each person to walk independently from his living area to school. Travel training included instructions, practice, praise, feedback, verbal reprimands, prompts, and edible reinforcers. Each resident began walking the entire distance to school independently during training and also began walking back to the living area, although the latter set of skills was not specifically trained. Following termination of the formal investigation, follow-up measures of 1 to 8 weeks showed the residents continued going to school independently. A survey of residential facilities in 43 states provided social validation for the seriousness of the problems associated with transporting seriously retarded persons to school. Also, time efficiency measures indicated that training independent travel resulted in reductions of staff time required in school transportation. Results were discussed in light of the potential contributions of behavior analysis in providing less restrictive environments for seriously handicapped persons.     

Less is not more: Further observations on nonlinguistic strategies

In an attempt to clarify the role of nonlinguistic preferences in children's responses to the words more and less, children 3–4 years of age were administered three tasks. Two of these required the child to indicate which of two arrays had more or less items, as instructed; the third task required the child to point to any one of two arrays. Children consistently selected the arrays with more items on all three tasks. The present finding of a response bias necessitates a reinterpretation of earlier studies of more and less. The results are discussed in terms of the full and partial semantics hypotheses as articulated by E. Clark.     

Availability and accessibility of information in the semantic memory of retarded and nonretarded adolescents

The availability of semantic information in storage and the accessibility of that information for retrieval were studied in retarded and nonretarded adolescents. In Experiment 1, 40 normal and 40 CA-equivalent (mean, 15 years) retarded subjects were required to retrieve information from semantic categories as well as to judge whether specific items were members of a given category. The results showed large IQ group differences on the retrieval task which could not be wholly accounted for by the items available in storage. Experiment 2 was designed as an attempt to remediate this retrieval deficit by introducing an organized retrieval plan consisting of subcategory cues. This organization facilitated retrieval as long as it was experimentally provided. Retrieval returned to its original level, however, when the cues were withdrawn. It was concluded that retarded persons had an accessibility deficit in addition to an availability deficit; one aspect of this accessibility deficit involved the failure to use spontaneously mnemonic strategies that were consistent with the semantic organization.     

Students' ratings of occupational dimensions of traditionally male and traditionally female occupations

The purpose of the present study was to investigate four traditionally male occupations and four traditionally female occupations on a number of dimensions which people use to judge the prestige or importance of a job. Workers were pictured on one form in their traditional roles and on a second form in nontraditional roles. Results indicated a tendency for subjects to give lower ratings to workers in nontraditional jobs. More importantly, for the two “objective” dimensions, money and education, boys and girls agreed on job ratings; however, on the two more “subjective” dimensions, respect and importance to the community, boys gave higher ratings to the male jobs, while girls gave higher ratings to the female jobs.     

Unweighting infants reveals hidden motor skills

We investigated the role of rate limiting factors in development using walking as a model system. The achievement of bipedal posture and locomotion are among the most significant achievements in an infant's first year, with poor balance and weak muscles long proposed as the rate limiting factors. Compensating for either may reveal upright motor skill that has not yet emerged in the infant's natural repertoire. To probe this question, we unweighted prewalking infants and measured their performance in various standing and walking behaviors while unweighted compared to baseline. Our secondary objective was to determine if the influence of unweighting was related to infants’ locomotor experience. Infants stood unsupported for longer durations with 20% or 40% unweighting. Infants took more independent steps and more steps with one hand held with 40% unweighting. No differences in transition to/from standing were observed. Locomotor experience was related to the influence of unweighting during cruising and walking with a push toy. This is the first report of more advanced motor skills—longer periods of unsupported standing and the emergence of independent walking—revealed by unweighting infants. We interpret our observations to suggest that the refinement of motor control needed to support bipedal posture and locomotion precedes the functional emergence of these skills in infants. In other words, the musculoskeletal components required for walking are slower to develop than the neurological factors – and consequently may be the rate limiters. We further suggest that training regimens including unweighting should be explored in infants with motor delays.     

Sexuality as an Integral Part of the Church's Being and Mission

The article draws on the experience of being part of the Reference Group on Human Sexuality and other debates on sexuality in the World Council of Churches to discuss the “Message of the 11th Assembly.” It makes explicit how issues of sexuality have been avoided and how they ground the understanding of theological perspectives and the church's being and mission. Finally, it presents alternatives to reclaim sexuality and make the movement of reconciliation grounded in a transformative and queer spirituality more concrete and truthful to people's lives – a sexy movement.

The equilibrium-point hypothesis is still doing fine

Within the present paper we provide the arguments that contradict Gottlieb's conclusions regarding the theoretical implications of kinematics of movements performed with unexpectedly changed inertial loads. First, the load associated changes in movement velocity presented by Gottlieb may be caused by apparent methodological differences, when compared to our earlier results. Moreover, the present data can be interpreted by the equilibrium-point hypothesis as well as by Gottlieb's hypothesis. Second, Gottlieb remains silent on findings related to the movement time and symmetry ratio that contradict predictions based on either torque control or Gottlieb's hypothesis. Therefore, we conclude that the data obtained on rapid movements performed with unexpected changes in inertial load support equilibrium-point hypothesis, rather that any of the torque control based models.
