The interference problem for the betting interpretation of degrees of belief

The paper’s target is the historically influential betting interpretation of subjective probabilities due to Ramsey and de Finetti. While there are several classical and well-known objections to this interpretation, the paper focuses on just one fundamental problem: There is a sense in which degrees of belief cannot be interpreted as betting rates. The reasons differ in different cases, but there’s one crucial feature that all these cases have in common: The agent’s degree of belief in a proposition A does not coincide with her degree of belief in a conditional that A would be the case if she were to bet on A, where the belief in this conditional itself is conditioned on the supposition that the agent will have an opportunity to make such a bet. Even though the two degrees of belief sometimes can coincide (they will coincide in those cases when the bet has no expected causal bearings on the proposition A and the opportunity to bet have no evidential bearings on that proposition), it is the latter belief rather than the former that guides the agent’s rational betting behaviour. The reason is that this latter belief takes into consideration potential interferences that bet opportunities and betting itself might create with regard to the proposition to be betted on. It is because of this interference problem that the agent’s degree of belief in A cannot be interpreted as her betting rate for A.     

Do you understand what you are reading?

This article discusses the concepts of literacy, theological literacy and literacy practices as a resource for understanding how tradition and faith/belief are intertwined. Against the background of recent elaborations of literacy within the field of literature and educational studies, the suggestion is made that “tradition” can be understood as a semiotic domain, i.e. a set of practices that recruits one or more modalities to communicate distinctive types of meanings. Theological literacy is accordingly defined as the ability to interpret, develop and communicate a theological semiotic domain. Literacy helps us to see that Christian faith/belief cannot be taught and acquired once and for all by learning a doctrinal content and a specific religious practice. At the same time, however, literacy nevertheless stresses the importance of knowing doctrinal content and religious practise, seeing that literacy is part of the process of shaping and construing faith and tradition.     

Burden, depression, and anxiety in caregivers of people with amyotrophic lateral sclerosis

Amyotrophic lateral sclerosis (ALS) is a progressive and fatal neurodegenerative disease caused by the degeneration of motor neurons. The burden for ALS caregivers is quite high. There are still few studies that have investigated the emotional impact of ALS care. We conducted a cross-sectional study among 40 ALS caregivers, assessing general worries, burden of care, depression, anxiety, perception of social support, and patients' severity of disease. Caregiver burden, depression, and anxiety were positively related with each other, and all these variables had a negative relation with social support. Patient's loss of physical functions was positively related with caregiver burden, anxiety, and somatic expression of depression. Caregivers expressed worries for their own health conditions. Given these results, we consider the hypothesis of an emotional-somatic impact of ALS care. The implications and limitations are discussed.     

Expected car use reduction in response to structural travel demand management measures

Selecting the appropriate travel demand management (TDM) measures aiming to reduce the environmental problems associated with private transportation demands a thorough understanding of the behavioral consequences of different measures. In this scenario based study, the expected car use reduction in response to one push measure (i.e. raised tax on fossil fuel), one pull measure (i.e. improved public transport), and a combination of the two measures were analyzed. The aim was to compare the expected car use reduction in response to the different TDM measures, the car use reduction strategies used to achieve this reduction, and factors important for the expected car use reduction (i.e. background factors, internal motivational factors (general intention and personal norm), and perceived personal impact of the measure). In a two step between-subject design, a sample of car users first answered a pre-questionnaire and subsequently three groups of car users (N = 274) each evaluated one of the TDM measures. Results demonstrated that the combined measure led to larger expected car use reduction compared to the measures evaluated individually and the reduction was mainly expected to be made by means of trip chaining and changing travel mode. Moreover, internal motivational factors, such as personal norm or general intention, and the perceived impact of the measure, were found to be important for the expected car use reduction in response to the TDM measures.     

Articulatory coding and phonological judgements on written words and pictures: The role of the phonological output buffer

Abstract

The ability of Italian subjects to make phonological judgements was investigated in three experiments. The judgements comprised initial sound similarity and stress assignment on pain of both written words and pictures. Stress assignment on both words and pictures as well as initial sound similarity on pictures required the activation of phonological lexical representations, but this was not necessarily the case for initial sound similarity judgements on word pairs. The first study assessed the effects of concurrent articulatory suppression on the judgements. Experiment 2 used a concomitant task (chewing), which shares with suppression the use of articulatory components but does not involve speech programming and production. The third experiment investigated the effects of unattended speech on the phonological judgements. The results of these three experiments showed that articulatory suppression had a significant disrupting effect on accuracy in all four conditions, while neither articulatory non-speech (chewing) or unattended auditory speech had any effect on the subjects' performance. The results suggest that these phonological judgements involve the operation of an articulatory speech output component, which is not implemented peripherally and does not require the involvement of a non-articulatory input system.     

Faith, Premarital Sex and Relationships: Are Church Messages in Accordance with the Perceived Realities of the Youth? A Qualitative Study in KwaZulu–Natal, South Africa

Since religious messages on life style have a strong impact in South Africa, it is important to assess how they relate to the situation for young people at risk of HIV infection. Nine focus group discussions were conducted with youth (n = 62), aged 13–20 years, from the Roman Catholic Church, the Lutheran Church, and the Assemblies of God. Young people were ambivalent toward sexual contacts since these generally were expected to be part of a relationship even though the church condemns premarital sex. Girls perceived the moral norms to concern them more than the boys for whom sexual needs were more accepted. These moral barriers lead to lack of information about protection and may increase the risk of HIV. The realities young people facing should be a major concern for the faith communities.     

Differences in Concentration Ability Among Low- and High-SES Israeli Students: A Follow-Up Study

Eighty students participated in a follow-up study investigating the relationship between the ability to concentrate and academic achievement among low-socioeconomic-status (LSES) and high-socioeconomic-status (HSES) 4th graders. The results indicated that the differences between the ability to concentrate and academic achievement found when the students were in the 1st grade (Norman & Breznitz, 1992) persisted, in part, to the 4th grade. Compared with HSES children, LSES children obtained significantly lower scores on measures of academic achievement and concentration. Additional measures of school behavior included in the present study revealed that LSES children were more likely to be characterized by aggressive-impulsive behavior. This behavior accounted for most of the differences found between HSES and LSES pupils on the academic and concentration measures.     

Variability and standardized test profiles in typically developing children and children with Williams Syndrome

Williams Syndrome (WS) is a developmental disorder, which due to its specific cognitive profile, has been of interest to multidisciplinary research in order to study the pathways between cognition, brain, and genes. Previous studies investigating individual performance on cognitive tasks have reported large variability within the WS cognitive profile, which has encouraged the investigation of WS subgroups. The current study compared the variability in performance scores on five verbal and non‐verbal standardized tests in 33 children with WS and in 33 typically developing (TD) children of a similar chronological age (CA). In contrast to previous studies, the current study did not find significant differences in variability in performance on British Picture Vocabulary scale, Test Reception of Grammar and Digit span Forward between WS and TD groups when CA was controlled for. However, there was significantly less variability in younger WS participants for performance scores on Pattern Construction compared to the TD group. In light of these results, methodological issues and the importance of taking CA into account in analyses will be discussed.     

The British Sign Language (BSL) norms for age of acquisition,familiarity, and iconicity

Research on signed languages offers the opportunity to address many important questions about language that it may not be possible to address via studies of spoken languages alone. Many such studies, however, are inherently limited, because there exist hardly any norms for lexical variables that have appeared to play important roles in spoken language processing. Here, we present a set of norms for age of acquisition, familiarity, and iconicity for 300 British Sign Language (BSL) signs, as rated by deaf signers, in the hope that they may prove useful to other researchers studying BSL and other signed languages. These norms may be downloaded from www.psychonomic.org/archive.
