An Experimental Computer-Based Educational and Career Exploration System

A major objective of the student guidance and counseling centers in high schools, junior colleges, and universities is to provide individualized aid to each student to help him reduce the uncertainty of his educational and vocational plans. Frequently, this objective is not fully satisfied because of information-handling problems. Two such problems are: (a) the fallibility of both counselor and student in memorizing, associating, and selectively recalling educational and vocational facts; and (b) the inability of the counselor and the student to devote sufficient time, patience, and energy to performing the enormous number of clerical steps involved in relating educational and occupational facts to pertinent information about the student. Computer-based information systems may be able to reduce these deficiencies considerably. This paper describes an experimental information system designed to be used by students as part of the total guidance services offered in schools. Such systems may aid both the student and the counselor.     

Responsibility diffusion and drive enhancement effects on risky shift1

Discussion produced expected risky and cautious shifts on choice dilemma items It was predicted from responsibility diffusion theory that, compared with low-anxious, high-defensive groups, high-anxious, low-defensive groups produce greater risky shift It was predicted from drive enhancement theory that, compared with low-anxious groups, high-anxious groups produce greater risky shift on risk-dominant items and greater cautious shift on caution-dominant items The results of two experiments failed to confirm either interpretation Surprisingly, significant shifts were obtained in a control condition     

Relationships among vocational training,income, and job complexity of high school dropouts and high school graduates

High school dropouts (N = 100) and high school graduates (N = 100), of which half of each group had received vocational training and the other half had not, were compared on data taken from the inactive employment applications of the Fort Walton Beach, Florida State Employment Office. The sample (N = 200) consisted of an equal number of males and females while 30% were minority group members. A two-way analysis of variance showed that completing vocational training was positively correlated with higher income and job complexity level. The existence or absence of vocational training was a more potent influence on income level and job complexity than was completion of high school.     

Reviewing the literature: A comparison of traditional methods with meta-analysis1

Meta-analysis is the name given to a set of techniques for reviewing research in which the data from different studies are statistically combined. Meta-analysts have criticized the more traditional qualitative methods of review on three principal grounds: (1) that relevant information is ignored in favor of a simplistic box count of the number of studies in which a particular relationship is and is not statistically significant; (2) that the sample of studies for review often contains important biases; and (3) that box counts ignore statistical interactions. Our discussion suggests that these criticisms are not intrinsic to qualitative reviews, but rather represent poor practices by reviewers using traditional methods. Moreover, although meta-analysis has some advantages, it is not without its unique limitations. Our comparison of both methods is applied to the qualitative literature review of Zuckerman (1979) and the meta-analysis of Arkin, Cooper, and Kolditz (1980) which reached different conclusions about the “existence” of self-serving attributions in studies of interpersonal influence.     

Interference and facilitation effects of primes upon verification processes

Priming effects on sentence verification were investigated. The semantic relation of the prime and the probe, and the interval between prime and probe presentation (SOA), were varied for both ambiguous and unambiguous sentences. Reaction time to decide that a sentence was true or false was longer if the preceding prime was a word that was unrelated to the probe than if the prime was the word “blank.” In contradiction of Posner and Snyder’s (1975) claim that conscious processes develop slowly, this result was found at SOAs as short as 250 msec. Verification performance was facilitated for both sentence types when the prime word was the first of the to-be-presented probe sentence, but the magnitude of the facilitation effects depended upon the truth value of the probe, the associative strength of the subject and predicate of the probe sentence, and upon SOA. These findings indicate that priming affects the processing of relations among concepts in semantic memory, as well as the encoding of the probe.     

Punishment of self-injurious behavior in natural settings using contingent aromatic ammonia

Contingent aromatic ammonia suppressed the self-injurious behavior (SIB) of two retarded children in clinic, home and school settings. In Study 1. several reversals demonstrated the effectiveness of a 3-s ammonia contingency in the deceleration of hair-pulling in the clinic after a momentary ammonia contingency was shown to be no different from differential reinforcement of other behavior (DRO). Family members and school personnel suppressed the behavior in the home, grandparents' home and school in multiple baseline fashion. Difficulties in long term maintenance were encountered and discussed. In Study 2, a multiple baseline across Trainers 1 and 2 in a preschool setting and mother at home demonstrated the effectiveness of response-duration ammonia in eliminating hand-biting. Complete suppression was maintained at a 1-year follow-up. These studies replicated the suppressive effects of aromatic ammonia, extended the findings to children with different SIBs in natural settings with family members and teachers as therapists, demonstrated the necessity for different durations of ammonia, and suggested that maintenance must be assessed and programmed rather than assumed.     

THE EFFECTIVENESS OF VERBAL INSTRUCTION ON TEACHING BEHAVIOR-MODIFICATION SKILLS TO NONPROFESSIONALS1

The effectiveness of a mastery criterion, lecture-based training program for teaching behavior modification to sheltered workshop personnel was evaluated. Staff performance was assessed in terms of: (1) verbal proficiency, as determined from a pre- and posttraining written exam, and (2) application proficiency, as measured by the frequency and appropriateness of staff responses to client behaviors. A direct count was made of the number of positive, negative, and neutral statements following client appropriate and inappropriate behaviors, and the number and type of client behaviors ignored. Thus, it was possible to determine the extent of generalization from classroom to applied settings, as well as the appropriateness of lectures for training specific performance skills. Lecture units introduced stimulus control procedures, shaping-chaining, and contingency management. Characteristic features of the training program were frequent testing, study objectives, immediate remediation, and contingent reinforcement. Verbal instruction was shown to be effective in improving subjects' verbal skills concerning behavior-modification principles, while only partially effective in improving application skills. There was an increase in the total number of staff-client interactions observed for all subjects, but only two of the response classes emphasized in the training program (reinforcing desirable client behavior and ignoring undesirable behavior) showed considerable improvement over pretraining levels. Despite this partial improvement, verbal instruction alone was shown to be insufficient for teaching the full range of behavior-modification skills required to function effectively in applied settings.     

Resistance to satiation of consummatory and instrumental performance

In three experiments rats received training in a straight alley under high hunger and then were tested satiated. Both eating and running continued to occur under satiation, but the two responses were not completely correlated, and continued running did not depend upon continued eating. Further, groups differed in their eating behavior, although all experienced the same satiation procedure, suggesting that eating under satiation is not just a reflection of incomplete satiation. Resistance to satiation of the running response was greater following partial reward than following consistant reward and tended to be greater following small reward training than large reward training, regardless of schedule of reward. Eating during satiation was greater following partial than following consistent reward and was greater if the same reward magnitude was given in satiation as in acquisition than if a different reward magnitude was given. It was suggested that resistance to satiation is an associative phenomenon. Eating and running occur during satiation because the stimuli present during satiation continue to elicit them. The differences between results using rewarded satiation and results using high drive extinction as measures of persistence were attributed to satiation being nonfrustrating.     

Field-dependence, sensation-seeking, and preference of paintings

College students (122 males and 88 females) completed the Group Embedded Figures Test measure of field-dependence, and Sensation-Seeking Scale, and performed preference ratings on 40 slides of paintings. Factor analysis revealed six hypothesized and one unhypothesized preference dimensions that underlay preference ratings of paintings. It was hypothesized that the cognitive structuring ability associated with field-dependence would result in certain relationships between field-dependence and preference for paintings. Further, it was hypothesized that preference for novel, complex, and dynamic experiences, associated with sensation-seeking, would result in certain relationships between sensation-seeking and preference for paintings. For the full sample, three of five hypothesized relationships between field-dependence and preference for paintings were obtained, while three of four hypothesized relationships were found between sensation-seeking and preference for paintings.
