The effect of a fading procedure upon the acquisition of control by an overshadowed auditory feature

Pigeons' key-pecking responses were reinforced in the presence of a compound stimulus that consisted of an auditory feature (a tone) and a visual feature (a light) and non-reinforced in the presence of a compound stimulus that was either a noise and a dark key, or noise and a light. In the condition where reinforcement trials differed from non-reinforcement trials on the basis of both auditory and visual features, the tone exerted very little control over responding on test. In the condition where reinforcement differed from non-reinforcement trials solely on the basis of the auditory features, an abrupt and a gradual introduction of the visual feature of the negative stimulus, a light, were compared for their effect upon control in the compounds. The tone acquired strong control in both cases. Evidence indicated that the tone had acquired control in the gradual condition without the occurrence of responses to the negative stimulus. An incidental finding was that when the negative stimulus consisted of a noise and a light, which was introduced abruptly, responding over the light dimension with tone, on test, was peaked at a point other than that light value used as positive and negative during training.     

Free-operant avoidance in the pigeon using a treadle response

A free-operant avoidance schedule was used to establish and maintain foot-treadle responding by two Homing, one White King, and two Carneaux pigeons. In the absence of responding, the interval between shocks equaled 10 sec. Each time a treadle response occurred the shock was postponed for 32 sec. Pigeons appear to learn the treadle response more quickly and use it to avoid shock more successfully than do rats bar pressing on similar schedules. The treadle response becomes highly stereotyped and interresponse time distributions obtained from terminal behavior appear very similar to data obtained from rats. It is concluded that the difficulty in training pigeons to avoid electric shock is not in establishing avoidance behavior but in attempting to evaluate such behavior with the key-peck response.     

The counselor's role in collective negotiations

The impact of professional negotiations on the current educational scene is examined and related to clarification of the school counselor role. Role confusion continues in the school situation, and negotiations may well be the way to bring about a change in the status quo. Negotiations for counselors are explored from the standpoints of dimensions of negotiations, implementation of negotiations, and attitude of professional associations. Conclusions are that negotiations have significant implications for counselor role delineation.     

Getting black kids into college

The gap between black and white in college enrollment is widening. The guidance counselor plays a key role in the drive to eliminate the differences between the races in preparation for college and to secure the scholarships and grants necessary for enrollment. Comparability in enrollment means about 850,000 black students on college campuses; about 400,000 are there now. Comparability in 1976 will mean about a million black students enrolled. Master Counselors are required for this job, both to work with the children and to press for more federal aid in this area.     

Characteristics of Schizogenic Families During a Joint Story-Telling Task

For a joint family story-telling task, families with a schizophrenic offspring were compared to normal families on the completeness and clarity of the final composite stories and on their interactional behavior. The composite stories from schizogenic families were more “vague and confused”, fragmented, and less complete as to the five components required to satisfy the task instructions. Schizogenic families displayed more conflict, failure, and confusion during the interactional task than control families, and, fathers and mothers of schizophrenic offspring displayed more “anxiety and tension”, “depressive mood”, “evasiveness” and “lack of interest” than fathers and mothers of normal families. Mothers of schizophrenic offspring were also described as more “hostile” than control mothers. Comparing schizogenic families from which the patient was absent during the task with schizogenic families with the patient present, and with control families, indicated that the central findings were not attributable to the immediate presence and participation of the schizophrenic member.
