Follow-up on welfare benefits received by Job Club clients

A follow-up was made of the welfare payments received by AFDC clients who had received job-finding counseling. At the 6th-month follow-up, welfare payments had been reduced by about one-half for the Job Club clients vs 15% for the control group.     

Science and behavior therapy: A survey of research in the 1970s

A representative sample of a decade of contributors to the journals Behavior Therapy, Behaviour Research and Therapy, Journal of Applied Behavior Analysis and the Journal of Behavior Therapy and Experimental Psychiatry was asked to report on their motivations for conducting studies that had been published in that journal. Results indicated that the primary motivation of behavioral researchers was to build on prior research through gathering and analysis of data to illuminate applied-clinical issues and validate treatment procedures. Few researchers reported consultation arrangements or efforts to replicate as their motivation for research. Most respondents described the training model in which they had received their doctoral education as oriented toward a scientist-practitioner approach rather than one that focused primarily on research, therapy or assessment training. Most respondents noted that their philosophy of behavior therapy at the time of the study in question to be applied behavior analysis or social-learning theory with far less being affiliated with a neobehavioristic mediational S-R model or cognitive behavior modification. These results are discussed within the context of the relevance of clinical research in behavior therapy and professional psychology.     

The effects of sex and fear level of subjects on the snake approach behaviour of dyads

Dyads, differing in composition in terms of sex and fear level of subjects, were video-recorded whilst interacting with a harmless snake. Approach measures were taken for all subjects in the form of latency of first touch, percentage time in contact with snake and intensity of interaction from no touching at all through to picking up. As hypothesized, ‘fearless’ subjects showed more approach than ‘fearful’, with latency giving the most significant difference. Male and female scores were not significantly different on any measure, although there was a significant interaction on latency between sex and fear level, due to the performance of fearful females. Contrary to hypothesis there was no evidence that males regardless of fear level showed any more approach when paired with a female partner. There was evidence in line with hypothesis that fearless females showed more approach when paired with other females. Fearless males showed more approach when paired with fearful partners and fearful females when paired with fearless partners. These results are discussed in terms of the literature on the laboratory study of human fear and therapeutic modeling.     

The air gap phenomenon in children's landscape drawings

The “air gap” phenomenon was found to be very common in the free landscape drawings of middle and later childhood. Three experiments are reported in which the contextual cues for such drawings were systematically manipulated. When subjects were supplied with drawing sheets constructed to imply the absence of the air gap, the phenomenon was eliminated in most of their drawings. When supplied with sheets constructed to imply its presence, most subjects produced air gap drawings using contextually provided reference lines. There were no consistent transfer effects across different cuing orders. The susceptibility of the air gap phenomenon to modification by task manipulation suggests that it results from problems of production rather than from defects in the child's internal representation of the world.     

Exercise, changes in aerobic capacity, and changes in self-perceptions: An experimental investigation

Subjects in an exercise training condition participated in a 10-week aerobic exercise class, whereas subjects in waiting-list control and independent control conditions did not. The results indicated that subjects in the training condition evidenced reliably greater improvements in physical fitness (aerobic capacity) and reported reliably greater improvements in their abilities and confidence in both the physical area (e.g., ability to run distances) and nonphysical area (e.g., frustration tolerance) than did subjects in the control conditions. On the other hand, improvements in physical fitness were not related to reported improvements in abilities and confidence. These findings are of interest because they indicate that some of the important personal changes that are associated with physical fitness training are not due to changes in fitness, but appear to be due to other factors (e.g., group participation and expectancies).     

History,knowledge, and essence in the early Marx

A careful study of the concept of essence which is found in Marx's early writings will show that his theory of knowledge does not involve, as is often claimed, the acceptance of an unknown thing-in-itself and does not imply that we can only know objects as they have been constituted for-us. We can know things as they are in-themselves. To show this will also require that we recognize and explain how the early Marx can hold that the object of knowledge is both constituted and that it reflects or copies things as they are in-themselves.     

Time-interval acquisition on a 6502-based microcomputer

A versatile machine language subroutine and accompanying interface circuitry enable a 6502-based computer to collect time intervals between data events that can be represented by voltage transients. Intervals within the range of 150 microsec to 13.98 min can be collected with a resolution of ±25 microsec. Electrical interface circuitry includes signal conditioning and optical isolation and also allows user-specification of threshold levels on the data line. The machine language software timing routine and sequential interval handler include a 24-bit interval timer, a 16-bit interval counter, user-specified number and length of acquisition periods, and an out-of-memory tester. Although presented for implementation on the Apple II series of microcomputers, the transportability of the routine to other 6502-based machines is addressed.     

Head-injury prevalence among community college students.

835 community college students were surveyed to establish the prevalence of head injury or illness. Results are compared to prevalence rates among 4-year college students.     

Radical Behaviorism,Stimulus Equivalence,and Human Cognition

The current paper represents an attempt to clarify the nature of the radical behaviorist’s perspective on human cognition. This attempt will involve an examination of recent behavioral research into the relationship between stimulus equivalence phenomena and symbolic behavior, and language more generally. This form of behavior analysis is offered as an alternative to, but not a replacement for, other methodological and conceptual approaches to psychology.
