The Insanity Defense Reform Act of 1984: Much ado about nothing

The Insanity Defense Reform Act of 1984(IDRA), passed in the wake of Hinckley (1981) and after two years of Senate and House testimony and debate, removed the “volitional” prong of the ALI test, leaving only the “cognitive” prong. Prior empirical research and speculation suggested that this corrective would not serve its intended purpose. In this experiment, 54 mock jurors received one of four insanity test instructions: IDRA, ALI, a wild beast/mens rea test, or no instructions. Results showed that the test instructions did not produce significantly different verdict patterns, or effect in any other way the relevant and determinative constructs that jurors used in four different insanity cases.     

Differential correlates of irrational belief

One hundred and ten students completed a battery which included Jones' Irrational Belief Test (IBT), and measures of subjective well-being, affect, alienation, personality, goal characteristics, and goat attainment. Correlations and canonical composites showed a general relationship between irrational beliefs and emotional difficulty, but the specific pattern differed for subgroups of IBT scales. Correlations supported the construct validity of IBT scales, but suggested they also reflect motives, conflicts, affects and personality characteristics. Interdependence of these processes was hypothesized and use of subscore composites rather than total IBT scores was suggested.     

Apple Picker: Computer software for studying human responding on concurrent and multiple schedules

Apple Picker, a software package for the Apple II microcomputer, is described. Subjects respond by searching for “apples” in two “orchards.” “Attempted pickings” may be reinforced according to random ratio or interval schedules. “Search” responses are recorded and may be examined either as rates of responding in the two orchards or visually as paths the subject has traced during the session.     

Fair equality of opportunity and decent minimums: a reply to Buchanan

Responding to criticism by Allen Buchanan in a Winter 1984 Philosophy and Public Affairs article on "The right to a decent minimum of health care," Daniels defends his thesis that if justice requires protecting equality of opportunity, then health care institutions should be governed by the principle of fair equality of opportunity because impairments of normal functioning, seen as impediments to opportunity, are obviated by good health care. He defines his concept of normal opportunity range, which is relative to certain social considerations, and shows that health care services affect the distribution of opportunity, but not the normal opportunity range, among individuals. He agrees with the criticism that his argument does not guarantee minimum health care or solve problems of resource allocation.     

Forgetting in retarded and nonretarded persons under conditions of minimal strategy use

Short-term memory processes of mentally retarded (mild, moderate, and severe) and nonretarded persons were compared in a delayed matching-to-sample task that minimized the use of verbal rehearsal. In addition to trials with delays up to 20 s, the inclusion of trials on which the sample and comparison stimuli occurred simultaneously made it possible to isolate memory and discriminability. Forgetting was most pronounced between the simultaneous and 0-s conditions, and nonretarded subjects forgot less than retarded subjects between these conditions. There were no group differences beyond the 0-s delay. Ease of strategy use failed to account for individual differences, and reported strategy use was not related systematically to performance. These findings are incompatible with the hypothesis that normal-retarded differences occur only on tasks involving effortful cognitive strategies. Differences between nonretarded and retarded groups in this study may be due to a failure in automatic encoding processes in retarded persons.     

Spirituality,health care,and bioethics

This article explores the relationship of spirituality to health care and bioethics in terms of the need and efforts of people to make sense of their lives in the face of illness, injury, or impending death. Moving beyond earlier associations with specific religious traditions, spirituality has come to designate the way in which people can integrate their experiences with their sense of ultimate meaning and related values. The holistic model of health care also affirms that one should not simply treat a body in pain, but respond to the suffering of the whole person within his or her full life. A narrative emphasis in ethics also maintains that ethical decisions occur within the framework of interacting life-stories, each of which embodies a certain core vision and set of values. In each instance it is the life stories of people, their lived narratives, that provide a common thread. The telling of these stories and the discernment of the lived spirituality they contain may assist persons in the process of achieving understanding, making decisions, and finding purpose in the experience of illness, injury, or disability.Maureen Muldoon, Ph.D., is Associate Professor in the Department of Religious Studies, University of Windsor, Windsor, Ontario, and Norman King, Ph.D., is Professor in the same department.     

The perception of 3-D structure from contradictory optical patterns

Two experiments investigated observers’ perceptions of 3-D structure when optical sources of information were contradictory. When motion and stereoscopic disparities specified different surfaces, the perceptual outcome depended strongly on the direction of curvature present within each modality. Previous research has shown that the perception of surface slant and curvature is anisotropic for both motion and stereo and that it depends on the direction in which it takes place. In the present experiments, the modality with the “effective” direction of curvature tended to dominate or suppress the perception of surfaces in the other modality with less effective curvatures. The results have implications for models which attempt to combine 3-D data from different optical sources.     

A general model for preferential and triadic choice in terms of centralF distribution functions

A model for preferential and triadic choice is derived in terms of weighted sums of centralF distribution functions. This model is a probabilistic generalization of Coombs' (1964) unfolding model and special cases, such as the model of Zinnes and Griggs (1974), can be derived easily from it. This new form extends previous work by Mullen and Ennis (1991) and provides more insight into the same problem that they discussed.
