An economical,humane, and effective method for short—term suppression of hand mouthing

Self-injurious behavior (SIB) is a serious health hazard, especially among individuals with severe and profound mental retardation, sometimes leading to drastic therapeutic measures. Environments in which there are long periods with minimal opportunities for constructive activity are conducive to the development of SIB, but even highly motivated, hard-working caregivers sometimes have difficulty providing sufficient personal interactions to prevent it. In this case study, one person's self-injurious hand mouthing was significantly reduced by analyzing her toy play and consistently providing her with preferred toys. The results showed that careful and consistent attention to assuring that preferred materials are available for self-entertainment may be an effective and efficient method for managing some cases of SIB during times when other activities and treatments are unavailable.     

An automated sound-localization chamber

A completely automated free-field sound-localization apparatus is described along with a behavioral technique that provides several advantages over previously available methods. With the apparatus, the ability to localize the source of a sound has been tested in a wide variety of mammals including cats, rats, squirrel monkeys, hedgehogs, and tree shews.     

Metatechnology: A technollogy for the safe,effective, and economical use of technology

Alarmed by Three Mile Island, Love Canal, and other disastrous deployments of new technologies, the public is demanding more voice in the decision-making on technology. To make this possible, it is proposed that metatechnology be evolved that will provide a practical technology for the safe, effective, and economical use of technology. A case history of a specific metatechnology is presented. Here the metatechnology enabled a realistic balancing of the benefits of mass screening of women by mammography against the hazards from the X-rays. By showing that the screening of women under 50 was counterproductive, this metatechnology helped to ban such screening in a program involving a quarter of a million women. The strategic mistake in setting up this and other technological programs was that the decisions were made by the technologists. They benefited the technologists but were not beneficial to the women. One of the potentials of metatechnology is that in its fully computerized versions it could be used directly by the public for decision-making on the deployment of technologies.     

THRIFTNET: An economical software package for interprocessor communications

THRIFTNET is a collection of programs created in response to the need to share computer resources across computer systems on the campus of the University of Mississippi. Using THRIFTNET, files may be transferred between machines so that devices and programs available on only selected systems may be used to process information collected on any machine. File transfer is accomplished in small blocks of 128 data bytes embedded in a modified bisynch protocol that checks for transmission errors. The direction of transfer is dictated by the user, so files on small machines may be sent to large machines and files on large machines may be received by small machines.     

An evolutionary perspective on effective vs. ineffective pick-up lines

This experiment examined women's impressions of men using various "pick-up" lines. Seventy women imagined being approached by a man using a flippant and flirtatious "pick-up" line, a direct complimentary line, or an innocuous line that masks his interest. His attractiveness varied too. They then considered him for long-term or short-term relationships. Matching a "good dad" hypothesis, they favored him for a long-term relationship if he used a direct or innocuous line instead of the flippant line, because the latter conveyed lower trustworthiness and intelligence. Matching a "good genes" hypothesis, they favored him for a short-term relationship if he was attractive instead of unattractive, regardless of his pick-up line, presumably because attractiveness signals heritable fitness. Limitations and theoretical implications are discussed.     

Teaching oddity and insertion to Head Start children: An economical cognitive intervention

Two interventions were offered to Head Start preschoolers. Half of the children played numerous learning set games designed to teach the children (1) the oddity principle and (2) how to insert objects into a series. Mastery of these concepts is theoretically an important aspect of school readiness. The other half of the children engaged in the I Can Problem Solve (ICPS) exercises, a program designed to increase the children's competency in recognizing and responding to other people's feelings. The children who played the learning set games became superior at oddity and insertions with manipulable objects, and generalized these games to workbook-like formats resembling those encountered in kindergarten. They also scored higher on the numeracy and memory scales of the McCarthy Scales of Children's Abilities, indicating that mastery of oddity and insertions may have served as foundations for further cognitive growth. The children who participated in the ICPS exercises became superior at creating solutions to interpersonal problems, as measured by the Preschoolers Interpersonal Problem Solving Scale. The differences in the outcomes indicate that both interventions were successful in their own domains. The advantage the cognitive intervention produced on the McCarthy Scales suggests that oddity and insertion abilities may be a foundation in fact as well as in theory for general cognitive growth at this age.     

An economical system incorporating obsolete computers in an operant conditioning laboratory

A variety of obsolete computers were used with a commercial interface device (Alpha Bus) to control animal (rat) operant chambers. Original 28VDC electromechanical equipment was also used in conjunction with the interface to reduce initial equipment costs and maintain broad compatibility. Effective response counting and event control in three separate operant chambers was achieved through the use of secondary processing available on the current interface device. Advantages of the present systems include low initial and maintenance costs, expandability, and adaptability to different computers and applications.     

An economical dispenser to improve control of food reinforcement in the rat

A hopper dispenser designed for the study of food reinforcement in rats is described. By using ordinary rat chow, it significantly reduces the cost of reinforcing rats with food. By preventing stockpiling, it also guarantees control of the accessibility, as well as the presentation of food.     

Storytelling: An enjoyable and effective therapeutic tool

Storytelling has great potential for stimulating insight and behavior change, particularly when client and clinician seem to have reached an impasse, as is frequently the case with adolescent clients. The storytelling process provides a viable alternative to the traditional therapeutic communication style in which the client is the only storyteller. It provides a means to circumvent client resistance and present new concepts and paradigms for healthy behavior. This paper provides a practical guide for the use of therapeutic metaphors and storytelling as an intervention technique, provides examples of successful interventions made through the storytelling process with both adolescent and adult clients, and outlines suggestions for the effective use of storytelling as a therapeutic tool.Joyce Divinyi, MS, a licensed professional counselor, is a consultant with The Wellness Connection, Peachtree City, Georgia, providing wellness education and mental health training programs and individual and family counseling services.

An inexpensive operant chamber interface for the VIC 20 microcomputer

An inexpensive interface to connect the VIC 20 (or other Commodore microcomputer) to a single operant chamber is described. This interface is equipped to accept as inputs three separate switch closures and produces five outputs, including one to elevate a food hopper. The uses of this interface for controlling experimental events and acquiring data in real time are discussed.     

An economical microcomputer design for the generation and display of timed visual stimuli: The TDL VDB

Recent developments in microprocessor-based technology should be of particular interest to psychologists concerned with perceptual and cognitive processes. This paper describes the advantages of a Z-80-based system that uses the Technical Design Labs video display board (VDB) for the generation and control of visual stimuli.     

An effective fixed-point theorem in intuitionistic diagonalizable algebras

Summary Within the technical frame supplied by the algebraic variety of diagonalizable algebras, defined by R. Magari in [2], we prove the following:LetT be any first-order theory with a predicate Pr satisfying the canonical derivability conditions, including Löb's property. Then any formula inT built up from the propositional variables q, p₁, ..., p_n, using logical connectives and the predicate Pr, has the same fixed-points relative to q (that is, formulas (p₁ ..., p_n) for which for all p₁, ..., p_n T((p₁, ..., p_n), p₁, ..., p_n) (p₁, ..., p_n)) of a formula ^* of the same kind, obtained from in an effective way.Moreover, such ^* is provably equivalent to the formula obtained from substituting with ^* itself all the occurrences of q which are under Pr. In the particular case where q is always under Pr in , ^* is the unique (up to provable equivalence) fixedpoint of .Since this result is proved only assumingPr to be canonical, it can be deduced that Löb's property is, in a sense, equivalent to Gödel's diagonalization lemma.All the results are proved more generally in the intuitionistic case.The algebraization of the theories which express Theor, IXAllatum est die 19 Decembris 1975     

An exploration of women's expectations of effective male and female leadership

University women (N=188) of varying ages (19–53) and work experience described their behavioral expectations of an effective male and female leader for levels of Consideration, Initiating Structure, Role Assumption, and Production Emphasis. In line with a sex role congruency view, it was hypothesized that an effective female leader would be expected to exhibit higher levels of Consideration behaviors, while an effective male leader would be expected to exhibit more Initiating Structure, Role Assumption, and Production Emphasis behaviors. The results provided only partial support for the sex role congruency hypothesis since an effective female leader was expected to exhibit higher levels of Consideration as well as higher levels of Initiating Structure. No sex differences were detected for Role Assumption or Production Emphasis behaviors. Further, while many similarities were noted among the women in their views of effective leadership, there were also systematic age-related differences among the women in their expectations, particularly with regard to their views of effective female leadership.Portions of this paper were presented at the annual meeting of the Southeastern Psychological Association, Orlando, Florida, March, 1986.     

An economical modification of radial immunodiffusion for the determination of immunoglobulins in the cerebrospinal fluid]

In a total of fifty cerebrospinal fluids, such immunoglobulins as IgG, IgA, and IgM were quantitatively determined in a parallel manner on LC partigen plates and on slides (SEVAC set of means of testing). The comparability of the two methods of test proved excellent with good precision. The sensitivity of IgA determination on slides was made higher, the measurability of all precipitates was improved, and the economic advantage increased by cutting the cost of one determination fifteen times.     

Studying reaction time with nonaging intervals: An effective procedure

The nonaging-intervals procedure, in which momentary probability of stimulus occurrence remains constant, is preferable in principle to varied or constant intervals for double-stimulation experiments on reaction time (RT). However, elevation of RT has uniformly been found at short waiting intervals on single-stimulation baseline tasks. Effects attributable to the first stimulus on double-stimulation tasks would thus be confounded. The required level baselines were obtained for both simple and choice reactions by combining the transit-signal method with nonaging intervals. Possible reasons for this success were the elimination of timekeeping error and psychological refractoriness. Results with precued full response information show the expected decline of RT with increase of precue-to-stimulus interval. Suggestions are given for the use of nonaging intervals for studying the attentional demands of movements and the influence of level of momentary probability on basic RT effects.
