New models in research and design: New concepts of unity in planning and policy-making

Van Lohuizen’s ideal of unity, must above all be seen as a challenge to attain the necessary integration of planning, research, and design to meet the requirements of a changing society. Though Van Lohuizen's ideas were influenced strongly by the rational and technical principles of the CIAM, he saw technology as a means to an end in an approach that is primarily based on humans and culture. In the ideas of Van Lohuizen, different dimensions can be traced. New developments in these dimensions are discussed in the article. There is no lack of innovative ideas and methods. Nearly all the ideas and methods discussed were developed in the forties, fifties, or sixties. On the basis of the incubation period required for introduction on a wider scale, it is now time for them to find greater favor with society. Following the years of a no-nonsense policy, it seems that in many fields there is a new need for a wider, more qualitative approach.

Analysis of the control exerted by a complex cooperation procedure

The study examined the effects of the availability of a non-cooperative response on cooperative responding when cooperation did not have to result in an equal distribution of work or reinforcers. Also, an attempt was made to determine if the cooperative responding was under the control of the cooperation procedure. Pairs of institutionalized retardates were tested in full view of each other. For each subject, reinforcers (money) were contingent upon responses on each of two panels: (1) a matching panel for working matching-to-sample problems, and (2) a sample panel for producing the sample stimulus. The matching panels of the two subjects were 6 m apart, but a subject's sample panel could be placed at different distances from his matching panel. For each subject, either his own or his partner's sample panel could be nearest his matching panel such that less walking was required to reach one sample panel than the other. Subjects could work either individually, by producing their own sample stimulus, or cooperatively, by producing the sample stimulus for their partner. Subjects selected whichever solution involved the least amount of walking. The importance of testing for control by the cooperation procedure was indicated by the findings that cooperative-like responses were not always under the control of the cooperation procedure.     

Testing measures of the quality of residential care: A pilot study

This paper summarizes the results from a pilot study, designed to test a method of measuring the quality of care provided in two residential units for severely mentally handicapped children. The overall aim has been to devise general measures of the learning conditions (the quality of care) within residential units, which relate to groups of clients, and which are equally applicable at different times of the waking day. Such measures will only constitute a helpful monitoring instrument if they are shown to be reliable; to have, at least, face-validity: to be based upon representative and accurate data; and if they differentiate between settings which, intuitively, appear to differ in the extent to which the clients' appropriate behaviour is prompted and reinforced.     

RECREATING THE SCENE: AN EFFECTIVE WAY TO PROVIDE DELAYED PUNISHMENT FOR INAPPROPRIATE MOTOR BEHAVIOR

A mediated punishment procedure that involved recreating a behavioral sequence by guiding the subject through the behavior in the situation in which it occurred was used to suppress several severe problem behaviors in two developmentally delayed children. The mediational procedure was first used with a 4-year-old autistic boy for biting and then for foot stomping. Next the procedure was used for stealing and hoarding behavior with a multiply handicapped 17-year-old girl. Results indicated that the procedure was effective and produced relatively rapid results. One advantage of the procedure is that it provides an opportunity for trained personnel to apply restrictive procedures to low frequency behavior that occurs in their absence rather than relying on less qualified staff to implement the procedure immediately after the behavior occurs.     

Cues-pause-point language training: Structuring trainer statements to provide students with correct answers to questions

This study assessed the applicability of Cues-Pause-Point language training procedures in teaching students to obtain information from the statements of others. Two mentally retarded subjects, one of whom was echolalic, received training on one set of stimuli but not on another. During training the subjects were encouraged to remain quiet before, during, and briefly after the presentation of statements and then verbalize (i.e., answer a question) using the verbal cue(s) that had been presented in the statement. Correct responding reached 100% to the trained stimuli and both subjects' responding improved to the untrained stimuli. Posttests revealed that subjects used the trainer's statements to answer novel questions. The results suggest that Cues-Pause-Point procedures may be useful in teaching severely retarded individuals the functional use of observing and listening to others' verbal behavior.     

A COMPARISON OF VIETNAMESE-AUSTRALIAN AND ANGLO-AUSTRALIAN MOTHERs' BELIEFS ABOUT INTELLECTUAL DEVELOPMENT*

Vietnamese- and Anglo-Australian mothers' beliefs about intelligence and its development were obtained through a structured interview. Twenty-five working-class Vietnamese, 32 working-class and 39 upper-middle-class Anglo mothers of five-year-old children were asked about the heritability and stability of intelligence, its importance in different life domains and the roles of parents and teachers in developing intelligence. Developmental timetables for the acquisition of certain intellectual abilities were also elicited. Culture emerged as a significant influence on mothers' beliefs considerably more than did social class or sex of their child. Vietnamese mothers perceived intelligence as more important than did Anglo mothers, had a more narrowly focused view of education and intellectual development, and expected later acquisition of intellectual abilities. These differences are consistent with traditional Vietnamese values.     

AN ANALYSIS OF SOME VARIABLES INFLUENCING THE EFFECTIVENESS OF REPRIMANDS

Although several studies have shown that social reprimands can function as punishers, no study reported to date has isolated any of the factors influencing reprimand efficacy. Three experiments were conducted to investigate several factors. Experiment 1 used an alternating treatments design and was conducted on two elementary school boys, one of whom was in a special education class. Results showed that verbal reprimands delivered with eye contact and firm grasp of the student's shoulders reduced disruptive behavior to a greater extent than did verbal reprimands delivered without eye contact and grasp. Both types of reprimand were more effective than a baseline condition during which disruptive behavior was ignored. Experiment 2 also used an alternating treatments design and was conducted on one elementary school boy. Results demonstrated that reprimands delivered from one meter away were considerably more effective than reprimands delivered from seven meters away. Experiment 3 used a reversal design and was conducted on two pairs of elementary school children, one a pair of boys and the other a pair of girls. Results demonstrated that reprimands delivered to just one member of the pair reduced the disruptive behavior of both members of the pair. Thus, the effects of reprimands “spilled” over to nonreprimanded students.     

Some implications for psychological research of early versus late term participation by college subjects

Several surveys of recent psychological literature have indicated that a large percentage of human subjects are introductory psychology students who are given the option of selecting when to participate in research which is either implicitly or explicitly required of them. The present study was conducted to investigate the possibility that those subjects who choose to participate early in the term differ in personality and in attitudes toward research from later term participants. Results indicated that early term males and females, as expected, were more academically oriented and more internally controlled than late term subjects; and early term males were more achievement oriented than their late term counterparts. Additionally, females were found to feel more positive toward research participation than males; while a large percentage of all subjects reported both suspiciousness of experimenter intent and a general and unexpected willingness to voluntarily participate as subjects. Possible effects of these findings on research results and conclusions were discussed, and suggestions for improvements aimed at reducing self-selection bias in college subject pools were made.     

LARGE-SCALE REDUCTIONS IN SPEEDING AND ACCIDENTS IN CANADA AND ISRAEL: A BEHAVIORAL ECOLOGICAL PERSPECTIVE

We assessed the effects of posted feedback and warning ticket programs on speeding and accidents in two cities. In Experiment 1, speeding feedback signs were effective even when 10 were used in Dartmouth, Nova Scotia, and reductions in speeding were associated with reductions in accidents. The effectiveness of the signs was correlated with the number of intersections and residences within 0.5 km beyond them, and the signs had no effect on untreated streets. In Experiment 2, posted feedback and a warning program reduced speeding and accidents on 14 streets in Haifa, Israel.
