An inexpensive 28-V timer circuit using solid state and relay devices

An easily constructed 28-V dc timer circuit is described. The circuit is as precise, reliable, and versatile as some commercially available units, but is much less expensive to construct.     

A biphasic 60-Hz synchronizer circuit for the recording of visually evoked responses in high-noise environments

A simple synchronizer clock circuit is described that aids in the rejection of 60-Hz noise from evoked potential measurements.     

A device for presenting attack opportunity as a reinforcer for operant behavior

A device is described which automatically measures barpresses reinforced by short opportunities to attack male mice. Data on barpress rates indicate rapid and reliable acquisition of preferences for reinforcer bars and rapid abolition of this preference when the reinforcement contingency is subsequently eliminated. The data are less reliable for reversal learning.     

Development of an on-line problem-oriented system for the evaluation of mental health treatment services

Current on-line assessment applications are limited to mimicking instruments designed for paper and pencil. The development of an instrument designed specifically for on-line technology is described. The instrument provides research data on treatment effectiveness, clinical information for treatment planning, and management information for resource allocation.     

Minicomputer presentation of speech stimuli

A brief introduction to minicomputer control of speech stimuli is presented. Several techniques that have proven useful in this area are described.     

Adaptation to delayed auditory feedback

Delayed auditory feedback disrupts the production of speech, causing an increase in speech duration as well as many articulatory errors. To determine whether prolonged exposure to delayed auditory feedback IDAFI leads to adaptive compensations in speech production, 10 subjects were exposed in separate experimental sessions to both incremental and constantdelay exposure conditions. Significant adaptation occurred for syntactically structured stimuli in the form of increased speaking rates. After DAF was removed, aftereffects were apparent for all stimulus types in terms of increased speech rates. A carry-over effect from the first to the second experimental session was evident as long as 29 days after the first session. The use of strategies to overcome DAF and the differences between adaptation to DAF and adaptation to visual rearrangement are discussed.     

Law enforcement and crisis intervention services: a critical relationship

Law-enforcement officers tend to look at traditional mental health services as being of little help to them in dealing with persons they encounter experiencing emotional emergencies. They are frequently skeptical that emergency mental health programs offer more than they deliver. Because of their traditional base as the primary, and frequently only, available emergency "field" service in a community, a mental health emergency program must have a cooperative working relationship with law enforcement to serve a community successfully. This paper describes the development and maintenance of such a relationship, designed to increase the police case-finding potential.     

The decision to return to college: Role concepts,personality, attitudes,and significant others

In two studies, personality, role concepts, and attitudes distinguished wives and mothers who decided to resume college from those who did not. College women and women about to resume college had more self-actualizing, achievement-oriented, and dominant personalities (California Psychological Inventory); broader, more personalized role concepts; more liberal attitudes; better educated husbands; and fewer children than housewives. Measurements before college return and during the second year at college indicated that college exposure did not significantly affect these variables. The single exception was that after college exposure, women no longer saw society as supporting their efforts to actualize their potentials.A version of this paper was presented at the 83rd Annual Convention of the American Psychological Association, Chicago, August 31, 1975.
