A Woman's Choice? — On Women, Assisted Reproduction and Social Coercion

This paper critically discusses an argument that is sometimes pressed into service in the ethical debate about the use of assisted reproduction. The argument runs roughly as follows: we should prevent women from using assisted reproduction techniques, because women who want to use the technology have been socially coerced into desiring children--and indeed have thereby been harmed by the patriarchal society in which they live. I call this the argument from coercion. Having clarified this argument, I conclude that although it addresses important issues, it is highly problematic for the following reasons. First, if women are being coerced to desire to use AR, we should eradicate the coercive elements in pro-natalist ideology, not access to AR. Second, the argument seems to have the absurd implication that we should prevent all women, whether fertile or not, to try to have children. Third, it seems probable that women's welfare will be greater if we let well informed and decision-competent women decide for themselves whether they want to use AR.     

Testing unidimensionality in polytomous Rasch models

A fundamental assumption of most IRT models is that items measure the same unidimensional latent construct. For the polytomous Rasch model two ways of testing this assumption against specific multidimensional alternatives are discussed. One, a marginal approach assuming a multidimensional parametric latent variable distribution, and, two, a conditional approach with no distributional assumptions about the latent variable. The second approach generalizes the Martin-Löf test for the dichotomous Rasch model in two ways: to polytomous items and to a test against an alternative that may have more than two dimensions. A study on occupational health is used to motivate and illustrate the methods.The authors would like to thank Niels Keiding, Klaus Larsen and the anonymous reviewers for valuable comments to a previous version of this paper.

What is it for a Life to go Well (or Badly)?: Some Critical Comments on Wayne Sumner’s Theory of Welfare

In an effort to construct a plausible theory of experience-based welfare, Wayne Sumner imposes two requirements on the relevant kind of experience: the information requirement and the autonomy requirement. I argue that both requirements are problematic. First, I argue (very briefly) that a well-know case like ‘the deceived businessman’ need not support the information requirement as Sumner believes. Second, I introduce a case designed to cast further doubt on the information requirement. Third, I attend to a shortcoming in Sumner’s theory of welfare, namely that it is unclear which of later and informed assessments are to be treated as authoritative when it comes to the evaluation of a person’s welfare. Finally, I suggest that, in combination with ‘welfarism’ (to which Sumner subscribes, and which has it that welfare is all that matters from a moral viewpoint), the information requirement entail morally troublesome conclusions: e.g. the conclusion that, from a moral point of view, we should, other things being equal, only to be concerned with the alternative that makes one person slightly better off in respect of welfare instead of also being morally concerned with the alternative that makes one person very happy.     

Odor production and utilization under conditions of nonreward and small reward

A series of five experiments was conducted to examine odor production and utilization under conditions of contrasting large and small reward. Using daily, eight-trial double-alternation sequences of reward (L)-nonreward (N) or small reward (S), i.e., LLNNLLNN and LLSSLLSS, appropriate patterning was shown only when an empty goalbox was initially encountered on N or S trials (Experiments 1–5). Manipulations designed to increase frustration, for example, preceding double-alternation training with a block of large-reward trials in Experiment 2, or increasing the L vs S ratio in Experiment 3, failed to yield patterning when small reward was presented at the start of the S-trial confinement period. Patterning was shown when small reward was presented at the end of the S-trial confinement (Experiments 4 and 5). Immediate vs delayed (30 sec) S or N trial goalbox removal failed to result in differences in patterning (Experiments 1 and 2). To distinguish odor production from odor use, subjects trained on an LLSSLLSS pattern preceded subjects trained on an LLNNLLNN pattern (Experiment 5). Because patterning failed to develop in the LLSSLLSS subjects and the first subject in the LLNNLLNN group, it was concluded that a discriminably different cue was not produced on S trials under the LLSSLLSS sequence when small reward was delivered at the beginning of the goalbox confinement period. Shifting small-reward delivery to the end of goalbox confinement resulted in the immediate display of patterning by the first LLNNLLNN subject, and the subsequent development of patterning by the LLSSLLSS subjects.     

Absolute auditory thresholds in three Old World monkey species (Cercopithecus aethiops, C. neglectus, Macaca fuscata) and humans (Homo sapiens)

We investigated the absolute auditory sensitivities of three monkey species (Cercopithecus aethiops, C. neglectus, and Macaca fuscata) and humans (Homo sapiens). Results indicated that species-typical variation exists in these primates. Vervets, which have the smallest interaural distance of the species that we tested, exhibited the greatest high-frequency sensitivity. This result is consistent with Masterton, Heffner, and Ravizza's (1969) observations that head size and high-frequency acuity are inversely correlated in mammals. Vervets were also the most sensitive in the middle frequency range. Furthermore, we found that de Brazza's monkeys, though they produce a specialized, low-pitched boom call, did not show the enhanced low-frequency sensitivity that Brown and Waser (1984) showed for blue monkeys (C. mitis), a species with a similar sound. This discrepancy may be related to differences in the acoustics of the respective habitats of these animals or in the way their boom calls are used. The acuity of Japanese monkeys was found to closely resemble that of rhesus macaques (M. mulatta) that were tested in previous studies. Finally, humans tested in the same apparatus exhibited normative sensitivities. These subjects responded more readily to low frequencies than did the monkeys but rapidly became less sensitive in the high ranges.     

Schedule-induced polydipsia in rats living in an operant environment

The effect of variations in interreinforcement interval on the temporal and distributional relation between feeding and drinking was continuously monitored. Rats were housed continuously in an operant chamber in which water was freely available, but lever pressing was required to obtain food (45-mg pellets). Initially, pellets were delivered on a fixed-ratio 1 schedule of reinforcement, which was followed by testing on response-initiated fixed-interval 15-, 30-, and 60-second schedules. The total number of discrete, daily meals (a period in which several pellets were earned in succession) was slightly higher during the fixed-interval schedules than during the fixed-ratio 1, but there was no systematic effect of fixed-interval length on meal frequency. Total water consumption, in contrast, increased dramatically as the interval was lengthened: both subjects consumed two to three times as much water on the fixed-interval 60-second schedule as on the fixed-ratio 1. The increased water consumption was the result of an alteration in the distribution of drinking relative to eating. During the fixed-ratio 1 condition, drinking occurred infrequently following individual food pellets and represented the smallest percentage of total drinking; drinking occurred predominantly just before or after a meal. As the fixed interval was lengthened, however, the frequency of postpellet drinking gradually increased and eventually comprised the largest proportion of daily drinking.     

Genetic Counseling Outcomes: Perceived Risk and Distress After Counseling for Hereditary Colorectal Cancer

Genetic counseling may turn risk information into cancer prevention behavior by modifying health beliefs and cancer-related distress. We assessed the effect of genetic counseling on these factors in 101 adult first-degree-relatives of colorectal cancer patients from families with known or suspected hereditary nonpolyposis colorectal cancer. Before counseling and once afterward, subjects completed self-report measures of perceived lifetime risk and cancer-distress. Most persons overestimated their cancer risk, and higher perceived risk was associated with believing that colorectal cancer cannot be prevented. Individual perceived risk changed after counseling, although mean perceived risk was unchanged. After adjusting for baseline risk, older persons and those with higher estimated objective cancer risk had larger postcounseling decreases. Distress after counseling was positively correlated with baseline distress and anxiety symptoms, and inversely correlated with tolerance for ambiguity. The findings suggest counseling interventions that should increase the likelihood of screening and offer hypotheses for future research.     

Moralizing the COVID-19 Pandemic: Self-Interest Predicts Moral Condemnation of Other's Compliance,Distancing, and Vaccination

The emergence of the novel coronavirus has put societies under tremendous pressure to instigate massive and rapid behavior change. Throughout history, an effective strategy to facilitate novel behaviors has been to morally condemn those who do not behave in an appropriate way. Accordingly, here, we investigate if complying with the advice of health authorities—for example, to physically distance or vaccinate—has emerged as a moralized issue during the COVID-19 pandemic. In Study 1, we rely on data (N = 94K) from quota-sampled rolling cross-sectional online surveys from eight countries (Denmark, Sweden, Germany, France, Italy, Hungary, the United Kingdom, and the United States). We find that large majorities find it justified to condemn those who do not keep a distance to others in public and around half of respondents blame ordinary citizens for the severity of the pandemic. Furthermore, we identify the most important predictors of condemnation to be behavior change and personal concern, while institutional trust and social distrust also play large but less consistent roles. Study 2 offers a registered replication of our findings on a representative sample of Britons (N = 1.5K). It shows that both moralization and condemnation of both vaccination and general compliance are best predicted by self-interested considerations.
