Additive Effects of Certainty,Severity, and Celerity of Punishment on Judgments of Crime Deterrence Scale Value1

The certainty and severity of punishment for crimes are commonly given credence as determinants of deterrence value, whereas celerity of punishment is not. Moreover, data are sparse and divided on the question of how certainty and severity components combine algebraically. Two experiments inspected the effects of certainty, severity and celerity of hypothetical punishments on judged deterrence value, and the form of their factorial combination. Judged deterrence scale values were obtained for eight hypothetical conditions of punishment for serious crimes. These conditions of punishment consisted of orthogonal combinations of two levels each of certainty, severity, and celerity and were administered to independent subjects. Strong effects of certainty and severity and moderate effects of celerity were found, and there were no interactions among the three variables. Thus, celerity is pertinent to judged deterrence value, and the three components of punishment clearly combine additively rather than multiplicatively. It is argued that despite the empirical results, certainty, severity, and celerity must, however, ultimately be showp to combine according to a multiplying rule. The Discussion centers largely on an analysis and justification for that argument.     

Timmermann,Forschler, and The Attempt to Bridge the Kantian‐Consequentialist Gap

Scott Forschler defends R. M. Hare's rationalist‐universalizing‐utilitarian moral approach against Jens Timmermann's critique of it. He argues that Timmermann fails to see that Kant's ethical rationalism might be consistent with utilitarianism, and argues that Timmermann merely assumes that Kant's deontology follows logically from his ethical rationalism. In Forschler's estimation, it has not been established that either Kant's or Hare's ethical rationalism is inconsistent with utilitarianism. This article, however, argues that, in his response to Timmermann on behalf of Hare's rationalist‐universalizing‐utilitarian approach, Forschler has overlooked something very significant at the foundational level of Hare's moral approach, and that this oversight undercuts his response to Timmermann. The analysis also invites a metaethical investigation of preference satisfaction as it is found in Hare's moral approach. The article uncovers some fundamental metaethical presuppositions in Hare's normative approach, presuppositions overlooked by Forschler.     

Paradigms and Personhood: A Deepening of the Dilemmas in Ethics and Medical Ethics

There are many calls for a definitions personhood, but also many logical and Wittgensteinian reasons to think fulfilling this is unimportant or impossible. I argue that we can consider many contexts as language-games and consider the person as the key player in each. We can then examine the attributes, presuppositions and implications of personhood in those contexts. I use law and therapeutic psychology as two examples of such contexts or language-games. Each correlates with one of the classic “theories” of ethics-deontology and consequentialism. But each is a large enough cluster to consider them as paradigms in a sense related to Thomas Kuhn's notion in The Structure of Scientific Revolutions. Showing the presuppositions about and “takes” on personhood together with the connections involved in the paradigms deepens the dilemmas we already know to be present.

Simultaneously contrasting anchors

Subjects were required to judge a series of weights in the presence of two opposing anchor weights, one heavier and one lighter than the series members. It was predicted that the anchors would enhance each other’s effectiveness (contrast). The findings are similar to that found for the single-anchor experiment, with the exception that, and contrary to prediction, the heavier-weight anchor reduced the effectiveness of the lighter-weight anchor. The opposite effect was not true. It is suggested that a pair of opposing anchors could be identified that would completely cancel each other’s effectiveness.     

Value and uncertainty as weighting factors in impression formation

An experiment was conducted to compare mathematical models describing how people combine information to form an impression of another person. Subjects rated how much they would like stimulus persons described by one or two adjectives. Subjects also reported their level of uncertainty about each evaluation. Models using the uncertainty measures to predict integration weights were no more successful than the equal weight averaging model. There was no evidence that extreme adjectives were given high weight. Information integration was best described by a model in which the more negative adjective in a pair is given more weight than the other adjective.     

Menatal addition: A test of three verification models

Three explanations of adults’ mental addition performance, a counting-based model, a direct-access model with a backup counting procedure, and a network retrieval model, were tested. Whereas important predictions of the two counting models were not upheld, reaction times (RTs) to simple addition problems were consistent with the network retrieval model. RT both increased with problem size and was progressively attenuated to false stimuli as the split (numerical difference between the false and correct sums increased. For large problems, the extreme level of split (13) yielded an RT advantage for false over true problems, suggestive of a global evaluation process operating in parallel with retrieval. RTs to the more complex addition problems in Experiment 2 exhibited a similar pattern of significance and, in regression analyses, demonstrated that complex addition (e.g., 14+12=26) involves retrieval of the simple addition components (4+2=6). The network retrieval/decision model is discussed in terms of its fit to the present data, and predictions concerning priming facilitation and inhibition are specified. The similarities between mental arithmetic results and the areas of semantic memory and mental comparisons indicate both the usefulness of the network approach to mental arithmetic and the usefulness of mental arithmetic to cognitive psychology.     

Secondary reinforcement and number of primary reinforcements

Pigeons' pecks on either of two concurrently available response keys produced secondary reinforcers according to independent one-minute variable-interval schedules. Different secondary reinforcers, in the presence of which the rates of primary reinforcement were equal, were associated with each key. The rate of pecking maintained by each secondary reinforcer varied directly, but nonproportionally, with the number of primary reinforcements given in the presence of the secondary reinforcer.     

Integration of Intention and Outcome Information by Students and Circuit Court Judges: Design Economy and Individual Differences1

In two experiments the subjects, who included State Circuit Court Judges, assigned a quantitative judgment of blame to hypothetical offenders as a function of level of intention and seriousness of outcome. In accordance with the findings of numerous other investigators using the Intent x Damage paradigm, averaged subjects appeared to follow an adding rule for the integration of intention and outcome damage information. Furthermore, and in keeping with a key methodological purpose of the research, equivalent averaged results were observed whether student subjects made just one judgment of a single Level of Intention x Level of Outcome Damage treatment combination (independent groups design) or multiple judgments of all possible such factorial treatment combinations (repeated measures design). However, statistical analysis of individual students' and individual judges' repeated measures showed that about half of them adopted an adding rule whereas the judgments of others conformed to an intention-only rule. Some implications of the findings are: (a) in critical respects students' results are quite generalizable since there were no striking student versus judge differences; (b) averaged outcomes conceal important interpretable individual differences in information processing that are highly commensurate for students and judges; and (c) there is thus a defensible and pragmatically desirable economy in the adoption of repeated measures designs for the study of individual persons in such less accessible categories as the Judiciary.     

British parents' beliefs about the causes of three forms of childhood psychological disturbance

Parents were asked to rate which of 40 items were likely causes of one of three types of psychological disturbance common among 9-year-old children, the symptoms of which were outlined in vignettes. Parents' accounts were consistent and coherent. Symptoms of hyperactivity were linked to poor diet, antisocial conduct to a lack of discipline and unhappiness at school, and emotional problems to breakdowns in interpersonal relations and unhppiness at school. However, a number of factors (socioeconomic difficulties, attachment risks, and organic dysfunction) that research suggests are risks to development were rated by parents as unlikely causes of problems. The implications of this mismatch between lay and expert views is examined.We would like to thank Dr. Margaret Thompson for her clinical advice as well as the parents who took part in the study.
