The program for academic survival skills (pass): Effects on student behavior and achievement

The effects of the Program for Academic Survival Skills (PASS), a group behavior management program, on behavioral observation data and standardized achievement test measures were investigated. Fifty-four of the 96 selected low-achieving, low-survival-skill students of normal IQ were assigned to an experimental condition in which their teachers used PASS. The remaining 42 were assigned to a control condition. Results indicated PASS produced significant gains in survival skills during its operation and one week following program termination in both reading and mathematics periods across grades 1–3. Findings for achievement indicated a significant gain for first-grade experimentals only in reading, with a similar but nonsignificant gain for first-grade mathematics.     

Grouping strategies, peer influence, and free time as classroom management techniques with first- and third-grade children

This study systematically investigated the effects of different procedures on classroom behaviors ranging from teacher designated seating groups and seating groups based on sociometric data to peer encouragement and free time reinforcers. Subjects were first- and third-grade children in classrooms using a Follow Through program model. Data were taken on the attending behavior of the children in small groups arranged by the teacher. The level of appropriate attending behavior was low and did not increase when the groups were restructured based on sociometric data. The introduction of instructions to the peer groups to help the child with his or her work brought about a major increase in the third-grade subjects' appropriate behavior. Appropriate attending behavior for the first-grade children did not increase to the predetermined acceptable level until a free time period for each peer group was made contingent upon the appropriate behavior of the subject in each group. Frequencies of verbal interactions suggested peer attention has an effect on the appropriateness of peer interactions.     

Job-finding club: A group-assisted program for obtaining employment

Although joblessness is a major problem, no method of job-counseling has been demonstrated to be superior to usual job-finding practices. The present study describes a new type of program, which has now been evaluated experimentally in a matched-control design. The new program was conducted in a group and stressed such distinctive techniques as mutual-assistance among job-seekers, a ‘buddy’ system, family support, and sharing of job leads. In addition, the program arranged special ways of using such common practices as searching want-ads, role-playing, telephoning, motivating the job-seeker, constructing a resume and contacting friends. Within 2 months 90 per cent of the counseled job-seekers had obtained employment vs. 55 per cent of the non-counseled job-seekers. All clients who attended the program regularly obtained employment. After 3 months, 40 per cent of the non-counseled job-seekers were still unemployed. The average starting salary was about a third higher for the counseled job-seekers. The present procedure appears to be an effective method of assisting a greater proportion of the unemployed to obtain jobs and more quickly, and at a higher salary than they could obtain when they used the usual job finding procedures.     

Child performance on discrimination tasks: Effects of amount of stimulus variation

Two independently conducted studies investigated stimulus variation effects on children's discrimination learning. The stimuli in the first study were generated by a conjunctive rule and were presented in pairs. Mean trials to criterion was significantly lower for the single-feature change treatment (17.4) than for the multiple-feature change treatment (29.9). Single-feature change-treatment transfer scores were significantly higher only for stimuli that differed in terms of one of the features. The second study not only replicated the initial finding concerning the single-feature change treatment but also found that students made more errors in reaching criterion when stimuli were generated by an exclusive disjunctive rule and were presented singly. For all tasks, the single-feature change treatment with stimuli presented in pairs was accompanied by fewer errors to criterion than the other treatments.     

Do the mentally retarded have poor memory?

The hypothesis that mentally retarded persons have a short-term memory deficit whixh is due to inadequate rehearsal strategies is reexamined. A reevaluation of results of a number of experiments suggests that normal and retarded persons differ on short-term memory tasks, and the superiority of normals is present from the time of initial stimulus exposure. While some evidence for slope differences in retention curves is found in a few tasks, it is not strong support for memory differences. The hypothesis that “memory” differences are due to differential encoding as a result of more adequate rehearsal by the normal subjects is unacceptable. If this were the case, some differences in slope of retention curves could be expected unless rehearsal beyond the encoding stage was totally precluded. The review points to a need for an empirical reevaluation of the issue with a full recognition that deficits in particular processes may characterize some retarded persons and not others.     

A test of causal sequences in two models for development of career-orientation in women

To evaluate the tenability of two causal orderings of variables in the development of career-orientation, responses of 92 college senior women to Need Achievement, Dating Frequency, and Career-Orientation items were analyzed. The postulated orderings were derived from two models: a compensatory model implying that failure in a woman's heterosexual affiliation leads to high nAch which, in turn, produces high C-O; an enrichment model suggesting that a woman's high nAch may lead to high C-O which, in turn, decreases heterosexual affiliation. Criteria for temporal sequences as per the Simon-Blalock correlational procedures rendered the enrichment model more tenable.     

On the formation of personal space and self-boundary structures in early human development: The case of infant stranger reactivity

Personal space and self-boundary are, respectively, sociological and intra-psychological concepts that refer to a complex of behavioral and subjective events between and within individuals. While there are large bodies of literature concerned with each of these concepts, literature that cuts across many disciplines of study, there has never been an integration of these concepts around specific human developmental issues. The present article focuses upon human infancy as a period in which both personal space and self-boundary phenomena can be observed. Developmental links between personal space and self-boundary phenomena in infancy and adulthood are outlined and discussed.     

The effects of parent-presented models and praise on the vocal behavior of their children

The combined and separate effects of parent-presented models and praise on specific vocalizations of three children (15, 17, and 20 months old) were investigated. The frequency of a specific vocalization was higher when parents modeled and praised it than when they did not. In addition, modeling and praise, when used in combination, had a greater effect on the frequency of specific vocalizations than when used separately. Three additional parents were asked to attempt, by any means they wished, to increase the frequency of a specific vocalization by their children. These parents used modeling almost, exclusively, and the children did not exhibit the specific vocalizations as frequently as did the children whose parents were instructed both to model and praise specific vocalizations.     

Quasireinforcement: Control of behavior by second-order interval schedules

Pigeons were trained on a variable-interval 66-sec schedule of reinforcement that was segmented into either fixed- or variable-interval 10-sec components. Three-second access to food followed some components according to the overall VI 66-sec schedule, but 3-sec periods of nonreinforcement followed the other components. With both FI 10-sec and VI 10-sec segments, overall response rates were generally higher when the completion of unreinforced segments was signaled by a red key (never paired with food) than when it was unsignaled. Response rates during the red-key periods dropped to zero. Brief presentations of the red key engendered the distinctive (FI or VI) patterns of responding which would be expected if each segment were followed by food. These data demonstrate behavioral control by brief stimuli which are not paired with primary reinforcement and show that such control may develop even when the sequences of behavior required to produce food or brief stimuli are variable in duration.     

Stimulus control and delayed reinforcement

Pigeons were tested for generalization along the line-orientation dimension, after being trained on various two-component multiple schedules. The first component contained either a variable-interval 1-min schedule of immediate reinforcement or an extinction schedule and was associated with a plain white key (S1). The second component contained a variable-interval 1-min schedule of delayed reinforcement and was associated with a black line on a white background (S2). The major results showed that (a) decremental gradients were obtained around the stimulus associated with the delayed reinforcement component when S1 was associated with extinction, but that incremental gradients were obtained when S1 was associated with immediate reinforcement, (b) the subjects' pretraining did not affect the generalization gradients if sufficient training on the terminal multiple schedule was provided, and (c) changing the S1 schedule from immediate reinforcement to extinction produced behavioral contrast if reinforcement was delayed for 10 sec during S2, but not if it was delayed for 20 sec.     

POLITICS: Automated ideological reasoning

POLITICS is a system of computer programs which simulates humans in comprehending and responding to world events from a given political or ideological perspective. The primary theoretical motivations were: (1) the implemention of a functional system which applies the knowledge structures of Schank and Abelson (1977) to the domain of simulating political belief systems; (2) the development of a tentative theory of intentional goal conflicts and counterplanning. Secondary goals of the POLITICS project include developing a representation for belief systems, investigating cognitive processes such as goal-directed inferencing, and the integration of several types of knowledge representations into a functional system.
