Interactive braille output for blind computer users

Blind readers were tested using two methods of reading text displayed by an Apple microcomputer. The first method employed an Optacon system, a device that displays tactile representations of single characters, and the second used an interactive single electronic braille cell that displayed grade 1 braille characters. The results demonstrated no difference in accuracy or reading speed between these two methods. Thus, the serial presentation of braille characters at a single position appears to be a viable method of information transfer between computers and braille readers.     

Instructional programs for psychology: A review and analysis

This paper presents 10 general observations about current software for instruction in psychology and examines selected examples employing four instructional techniques for computer-assisted instruction. We find that although the number of programs employing experimental or data-oriented approaches to psychology as a primary vehicle of instruction is increasing, tutorial drill and practice programs and gaming are not well represented.     

FORTRAN subroutine for an EEG feedback digital filter

A method of constructing digital filters is outlined and illustrated in an application for research uses of EEG feedback. The method is based on least squares estimation with geometric weighting. Old data in the time series are discounted according to age, as new data arrive. Recurrence relations are used, allowing the computations to be performed in real time. A FORTRAN digital filter is formulated that simultaneously estimates (1) the spectral power in a band centered at a target frequency, (2) the total spectral power, and (3) the dominant frequency.     

The family void: treatment and theoretical aspects of the synchronous family paradigm

The synchronous paradigm is a model of families whose members remain uninvolved and disconnected from each other yet somehow maintain relatively unvarying or even rigid patterns of behavior. In the synchronous paradigm, calm agreement and harmonious unity of action are valued above all. The concept of synchronous operation was first formulated by Constantine to solve certain theoretical problems growing out of the work of Kantor and Lehr. The theory has been elaborated upon through linkages established with other clinical and theoretical models of family dysfunction. Clinical experience in treating synchronous families has now contributed more detailed and practical understanding. Clinically, disabled synchronous families may present as bland, boring, or even death-like. They may have considerable difficulty accommodating to necessary developmental changes or to the demands of life crises, employing a variety of strategies to maintain the appearance of synchrony at the expense of adaptation. Their ability to ignore change and to absorb interventions can tax the abilities of even the most creative and energetic therapist. On the other hand, the quiet efficiency of the family and the social sensitivity of its members can be strong assets. Awareness of their strengths and special vulnerabilities can help the family therapist work more effectively with synchronous families.     

Twenty years of family therapy in Israel: a personal journey

This article is a personal statement of my beliefs and practice of family therapy, from the time I first introduced the concept to Israel over twenty years ago to the present day. It reflects the evolution and changes in my clinical work against the background of major developments in the field of family therapy.
