When is the gift given? Organ donation,social representations,and an opportunity to register

The gift of life doctrine underpins Australia's approach to organ donation: in legislation, clinical practice, community awareness campaigns, and educational activities. In this paper, we present an approach that situates an understanding of organ donation within a social representation framework as a system of values, ideas, and practices. In cadaveric donation, the final giving‐of‐the‐gift can never be by the donor, leading us to ask where the potential donor's decision to give the gift really lies. We present research from three studies that explored the relationship between what was socially understood about organ donation and the registration of donation intent. Drawing from three socially and culturally diverse populations, we asked people working in a corporate city institution and those attending two football matches in the outer city area to complete a word‐association task and Likert‐scale belief questions about organ donation—followed by an opportunity to register immediately on the Australian Organ Donor Register. Driven by the interdependent themata of life/death and self/other, the gift of life doctrine is inextricably linked with the loss of life emerging as both positive and negative beliefs allowing their relationship to actual registration behaviour to be observed. Our findings suggest that in many instances, the potential donor's genuine desire to give the gift lies in the tension between positive and negative beliefs, manifesting as a consent registration when the positive beliefs about donation prevail and an immediate opportunity to register is available.

The question‐behaviour effect in intergroup attitudes research: When do attitudes towards a minority predict a relevant behaviour?

We hypothesised that the question‐behaviour effect, referred to as the influence of questioning about a given behaviour on its subsequent performance, is a relevant issue when exploring the external validity of intergroup attitudes. In a pair of studies, we have corroborated that merely expressing attitudes towards the Jewish minority affects people's relevant behaviour towards this group. In an Internet study, participants who first completed verbal attitude measures were more likely to donate to a Jewish organisation compared to those who completed the measures after making the decision to donate. Moreover, responses to attitude measures of various types and donating to the Jewish organisation were correlated when attitudes had been expressed in the first step. When attitudes were measured after the decision to donate, only the responses to the traditional anti‐Semitic scale were correlated with this behaviour. In the field study, in which the time interval between attitude and behaviour measures was introduced, no question‐behaviour effect was observed. We explain the results with reference to cognitive dissonance and attitude accessibility mechanisms and discuss them in a broader context of attitude‐behaviour research.

Martin's Axiom,Omitting Types,and Complete Representations in Algebraic Logic

We give a new characterization of the class of completely representable cylindric algebras of dimension 2 #lt; n w via special neat embeddings. We prove an independence result connecting cylindric algebra to Martin's axiom. Finally we apply our results to finite-variable first order logic showing that Henkin and Orey's omitting types theorem fails for L _n, the first order logic restricted to the first n variables when 2 #lt; n#lt;w. L _n has been recently (and quite extensively) studied as a many-dimensional modal logic.     

When the self represents the other: a new cognitive neuroscience view on psychological identification

There is converging evidence from developmental and cognitive psychology, as well as from neuroscience, to suggest that the self is both special and social, and that self-other interaction is the driving force behind self-development. We review experimental findings which demonstrate that human infants are motivated for social interactions and suggest that the development of an awareness of other minds is rooted in the implicit notion that others are like the self. We then marshall evidence from functional neuroimaging explorations of the neurophysiological substrate of shared representations between the self and others, using various ecological paradigms such as mentally representing one's own actions versus others' actions, watching the actions executed by others, imitating the others' actions versus being imitated by others. We suggest that within this shared neural network the inferior parietal cortex and the prefrontal cortex in the right hemisphere play a special role in the essential ability to distinguish the self from others, and in the way the self represents the other. Interestingly, the right hemisphere develops its functions earlier than the left.     

An exploratory investigation into the self-regulatory processes influencing drug driving: Are young drivers more externally regulated?

An upward trend in drug driving has been observed in several countries around the world. Research suggests that younger drivers are more likely to engage in drug driving compared to older drivers. There is also evidence to suggest young drivers differ from older drivers in their capacity for self-regulation. Despite this, research has yet to explore the impact of age on the self-regulatory processes with regard to decisions to drug drive among drug users. A total of 507 Queensland drivers (72.8% female), who reported ever taking an illegal drug, were involved in the research. Participants completed an online questionnaire, which collected demographic and drug consumption information, as well as items assessing the self-regulatory processes influencing drug driving, and drug driving behaviour. Regardless of age, participants reported a tendency towards internalised regulation. However, results suggest that young drivers (aged 18–24 years) feel greater belongingness to people who promote safe transport decisions after taking drugs, compared to drivers aged 25 years and over. Interaction effects revealed that for young drug takers, feeling greater relatedness, along with perceiving competence and importance in planning alternative transport after taking drugs, can be protective against drug driving behaviours. Significant predictors of drug driving were lower relatedness, greater perceived pressure to drug drive, lower effort/importance to plan safe alternatives after taking drugs, being of older age, and greater drug abuse. Counterintuitively, perceiving more options (choice) to take alternative transport after taking drugs also predicted the offending behaviour. The results of this study suggest that enhancing drivers’ competency to make (and value) safe driving decisions is a critical step for road safety.     

Hostile/Helpless maternal representations in pregnancy and later child removal: A pilot study

This article presents the results of a small pilot study examining links between Hostile/Helpless (HH) representations of caregiving in pregnancy and later child removal by child protective services. The sample was drawn from a replication study of the Minding the Baby^® attachment‐based home‐visiting intervention conducted in the United Kingdom, serving young first‐time mothers in under resourced communities. The HH classification system (Lyons‐Ruth et al.) was adapted for use with the Pregnancy Interview (PI) (Slade); 26 PIs were assessed (coders blinded) in a sample that included 13 mothers whose infants were removed from custody due to anticipated or documented maltreatment within 2 years of childbirth, and 13 mothers who did not have their infants removed. Mothers whose infants were removed from their custody had significantly higher HH scores than mothers of infants who were not removed from their care (F(1, 24) = 14.500, p < .001), and the relation between overall HH classification and infant removal status was also significant (χ²(1, N = 26) = 12.462, p < .001). Results suggest that prenatal maternal caregiving representations may predict postnatal relationship disruptions, and indicate the need for larger studies further testing this prenatal approach to maltreatment risk assessment in at‐risk populations.     

Visual and Affective Multimodal Models of Word Meaning in Language and Mind

One of the main limitations of natural language-based approaches to meaning is that they do not incorporate multimodal representations the way humans do. In this study, we evaluate how well different kinds of models account for people's representations of both concrete and abstract concepts. The models we compare include unimodal distributional linguistic models as well as multimodal models which combine linguistic with perceptual or affective information. There are two types of linguistic models: those based on text corpora and those derived from word association data. We present two new studies and a reanalysis of a series of previous studies. The studies demonstrate that both visual and affective multimodal models better capture behavior that reflects human representations than unimodal linguistic models. The size of the multimodal advantage depends on the nature of semantic representations involved, and it is especially pronounced for basic-level concepts that belong to the same superordinate category. Additional visual and affective features improve the accuracy of linguistic models based on text corpora more than those based on word associations; this suggests systematic qualitative differences between what information is encoded in natural language versus what information is reflected in word associations. Altogether, our work presents new evidence that multimodal information is important for capturing both abstract and concrete words and that fully representing word meaning requires more than purely linguistic information. Implications for both embodied and distributional views of semantic representation are discussed.     

The Formal Structure of Kind Representations

Kind representations, concepts like table, triangle, dog, and planet, underlie generic language. Here, we investigate the formal structure of kind representations—the structure that distinguishes kind representations from other types of representations. The present studies confirm that participants distinguish generic-supporting properties of individuals (e.g., this watch is made of steel) and accidental properties (e.g., this watch is on the nightstand). Furthermore, work dating back to Aristotle establishes that only some generic-supporting properties bear a principled connection to the kind, that is, are true of an individual by virtue of its being a member of a specific kind (e.g., telling time for a watch). The present studies tested the hypothesis that principled connections are part of the formal structure of kind representations. Specifically, they tested whether they structure a newly learned kind representation. Experiment 1 found that introducing a property of a newly encountered novel kind in any one of four linguistic frames that provide evidence that a property has a principled connection to a kind (e.g., “It has fur because it is a blick”) led participants to infer a different conceptual consequence of principled connections (i.e., “There is something wrong with this blick, which does not have fur”) for which they had no direct evidence. Two introduction frames that provided no evidence for principled connections (e.g., “Almost all blicks have fur”) did not generate the same consequence. Experiment 2 found that all of the targeted properties were generic licensing, irrespective of the introduction frame. That the distinction between properties that bear principled connections to their kinds, and merely generic-supporting properties structures novel kind representations, provides strong evidence that this distinction is part of the formal structure of kind representations.
