On separability of and interference between tracking dimensions in dual-axis tracking

Time-shared tasks may conceivably be separable or integral. A case in which the question of separability seems quite relevant is dual-axis tracking. To test the interaction between tracking dimensions, we first studied whether they interfere with each other. Practiced subjects performed tracking on one or two axes, with or without feedback indicators and with or without a requirement to allocate resources unevenly between axes. They also performed with or without a concurrent binary classification of visually presented digits which were presented within a moving square that served as the target for tracking. Small deficits were found in the performance of both tracking and digit classification when performed together. However, the conditions of tracking did not have a discernible effect on either tracking or digit classification. Hence, the introduction of a second tracking axis probably does not have harmful consequences either on tracking itself or on any other task time-shared with tracking. Further studies were conducted to examine whether the absence of an effect of number of tracking axes is dues to their integrality. Ordinary position tracking was paired either with another similar task on the other axis or with a novel sort of tracking in which subjects had to continually match sizes of moving rectangles. Tasks were paired under both divided-attention and focused-attention instructions. No interference on position tracking was observed even when the types of task on the two axes differed, and no other evidence for integrality of the homogeneous task pairs was found.

Performance of retarded adolescents and nonretarded children on one- and two-bit logical problems

Groups of adolescents of retarded and borderline intelligence, ranging in IQ from 44 to 80 and in mean MA (mental age) from 8 to 12 yr, and groups of nonretarded children ranging in mean MA from 6 to 12 yr, were given logical problem solving tasks. In the nonretarded groups, on a one-bit problem only the kindergarten children (mean MA = 6 yr) failed to perform above chance, and were not tested further. On a two-bit problem, only the first graders (mean MA = 7 yr) failed to perform above chance.Conversely, in the low IQ groups, only the borderline group (mean MA = 12 yr) performed reliably above chance on the one-bit problem, and none performed above chance on the two-bit problem. There is a profound deficiency in low IQ individuals on certain tasks requiring logic and foresight, and MA markedly over-estimates their performance relative to the performance of nonretarded individuals.     

Sweet Gifts: A Jewish Response to Gilbert Meilaender

Judaism, like Gilbert Meilaender, analogizes food and sex. Traditionally, Judaism saw the primary purpose of sex as procreation, the fulfillment of a Biblical mandate. It did not, however, link sex to the Garden of Eden story, and it acknowledged that sex was also important for couples' bonding. While Meilaender sees bonding as a value co-equal with procreation, Judaism traditionally kept procreation as the primary goal. Couples were encouraged to have sex when infertile and were permitted contraception when pregnancy endangered life, but whenever possible, they were directed to also have sex for procreation. Many modern rabbis, in agreement with Meilaender, permit contraception in order to foster bonding as a separate goal of sex. However, reproductive technology is seen, in Judaism, as partnership with God, allowing for a process of birth that is as natural as the process of producing food by farming. Last, when sex is permitted, Judaism celebrate the joy attendant to sex as a Divine gift.     

Intensive Gestalt Group Therapy with Schizophrenics

Abstract

Teaching group therapy is an essential aspect of graduate studies within the helping professions. Existing models discuss four basic elements required for such training: experience, observation, supervised practice, and theory. The present paper offers a model for a group therapy seminar based on these four elements and organized along developmental concepts. Clinical observations of 120 psychology students who participated in the seminar were gathered over a five-year period. Teaching techniques included supervised observation, fish-bowl, one-way mirror, and a final paper integrating theory and practice. The seminar enabled students to practice and to theorize about group processes, both as participants and as co-leaders. Seminar outcomes and conclusions are discussed.
