Some punishing effects of response-force

The present experiment explored the punishing effect of different response-force requirements by means of a two-operant design analogous to a two-component chain schedule. The first component of the chain required a lever pull through 0.25 in. (0.64 cm) at 1 lb (4.45 N) of force. The second component required a lever pull through an additional 0.75 in. (1.90 cm) with the force varied between sessions from 1 lb to 50 lb (4.45 N to 223 N). Completion of the second component of the chain was reinforced after variable intervals averaging 1 min. The average rate of first-component response decreased as the force requirement for second-component responses was increased. This rate reduction did not appear to be due to increased response duration, “fatigue”, or differing rates of reinforcement. If the force requirement for the second-component response is viewed as a consequence for the first-component response, then the results of the experiment show that a high force requirement is a punisher.     

Reinforcing self-help group activities of welfare recipients

The attendance rates of welfare recipients at self-help group meetings was compared when supplementary reinforcement was given for attending and when it was not. Reinforcers included donated items, such as clothing and household goods, and information about welfare services. It was found that the attendance at meetings averaged three recipients per meeting without reinforcement and 15 recipients per meeting with reinforcement. There was evidence that attendance was associated with participation in other self-help activities. It was concluded that practical forms of reinforcement can be found to maintain the participation of severely disadvantaged populations in self-help groups.     

The Development of an SVIB Interest Scale for School Counselors

A professional school counselor key was developed on the Strong Vocational Interest Blank using Campbell's revised procedures. Of the 403 counselors initially contacted, 340 responded. Of this number, 203 were identified as professional counselors and were included in the professional school counselor scale. Each of these individuals was fully certified, possessed three or more years' experience as a counselor, was a member of a professional guidance association, and was thoroughly satisfied with his job as a counselor. Differences between professional counselors and non-professional counselors seemed to indicate a greater people-orientation in the professional counselor group. This was further supported by relationships of the professional counselor key with other scales on the SVIB.
