Three experiments examined whether the mere priming of potential action effects enhances people’s feeling of causing these effects when they occur. In a computer task, participants and the computer independently moved a rapidly moving square on a display. Participants had to press a key, thereby stopping the movement. However, the participant or the computer could have caused the square to stop on the observed position, and accordingly, the stopped position of the square could be conceived of as the potential effect (...) resulting from participants’ action of pressing the stop key. The location of this position was primed or not just before participants had to stop the movement. Results showed that priming of the position enhanced experienced authorship of stopping the square. Additional experimentation demonstrated that this priming of agency was not mediated by the goal or intention to produce the effect. (shrink)
Critical realism is a philosophy of science, which has made significant contributions to epistemic debates within sociology. And yet, its contributions to ethnographic explanation have yet to be fully elaborated. Drawing on ethnographic data on the health-seeking behavior of HIV-infected South Africans, the paper compares and contrasts critical realism with grounded theory, extended case method and the pragmatist method of abduction. In so doing, it argues that critical realism makes a significant contribution to causal explanation in ethnographic research in three (...) ways: 1) by linking structure to agency; 2) by accounting for the contingent, conjunctural nature of causality; and 3) by using surprising empirical findings to generate new theory. The paper develops the AART research schema and illustrates its strengths by employing a Bourdieusian field analysis as a model for morphogenetic explanation. (shrink)

The central question in this article concerns the implications of developments in the rearrangement of tasks in health care, particularly for nurses in terms of their duties and responsibilities. Attention is focused on the transfer of medical tasks from physicians to nurses. An investigation was carried out on the impact of the rearrangement of tasks from the perspective of health care law on the legal framework of the nursing profession. From case law it can be concluded that a number of (...) specific conditions have to be met, such as mentoring, supervision and audit, orders and instructions, clear agreement about task allocation, comparing information, and making certain that the person who is given the instruction is sufficiently competent and experienced to carry it out. Although the rearrangement of tasks fits into the existing legal framework, changes in the health professions have to be met more flexibly. (shrink)
The Netherlands does not have any specific legislation pertaining to human biological materials and data collection by biobanks. Instead, these issues are governed by a patchwork of laws, codes of practices, and other ethical instruments, where special emphasis is given to the right to privacy and self-determination. While draft legislation for biobanking was scheduled to enter into force in 2007, as of mid-2015 such legislation was still under consideration, with the intent that it would focus particularly on individual self-determination, the (...) interests of research, the use of bodily materials collected by biobanks for criminal law purposes, and dilemmas around results that are clinically relevant for biobank participants. Under the current framework, the amount of privacy protection afforded to data is linked to its level of identifiability. International sharing of personal data to non-EU/European Economic Area countries is allowed if these countries provide adequate protection. (shrink)
It is generally assumed that storing predictive relations between two events in memory as bi-directional associations does not require conscious awareness of this relation, whereas the formation of unidirectional associations that capture the direction of the relation does. This study reports a set of experiments demonstrating that unidirectional associations can be formed even when awareness of the relation is actively prevented, if attention is “tuned” to process predictive relations. When participants engaged in predicting targets based on cues in an unrelated (...) task before the actual acquisition phase, unidirectional associations were formed during this acquisition phase even though E1 was presented subliminally. This suggests that although processing the relation between events may often be accompanied by awareness of this relation, awareness is not a prerequisite for the formation of unidirectional associations.

The book series Linguistische Arbeiten (LA) publishes high-quality work in linguistics that addresses current issues in synchrony and diachrony, theoretically or empirically oriented.
This is the first exhaustive investigation of gradience in syntax, conceived of as grammatical indeterminacy. It looks at gradience in English word classes, phrases, clauses and constructions, and examines how it may be defined and differentiated. Professor Aarts addresses the tension between linguistic concepts and the continuous phenomena they describe by testing and categorizing grammatical vagueness and indeterminacy. He considers to what extent gradience is a grammatical phenomenon or a by-product of imperfect linguistic description, and makes a series of linked (...) proposals for its theoretical formalization.Bas Aarts draws on, and reviews, work in psychology, philosophy and language from Aristotle to Chomsky., and writes clearly on a fascinating and important aspect of language and cognition. His book will appeal to scholars and graduate students of language and syntactic theory in departments of linguistics, philosophy and cognitive science. (shrink)
Affect misattribution occurs when affective cues color subsequent unrelated evaluations. Research suggests that affect misattribution decreases when one is aware that affective cues are unrelated to the evaluation at hand. We propose that affect misattribution may even occur when one is aware that affective cues are irrelevant, as long as the source of these cues seems ambiguous. When source ambiguity exists, affective cues may freely influence upcoming unrelated evaluations. We examined this using an adapted affect misattribution procedure where pleasant and (...) unpleasant responses served as affective cues that could influence later evaluations of unrelated targets. These affective cues were either perceived as reflecting a single source , or as reflecting two sources suggesting source ambiguity. Results show that misattribution of affect decreased when participants perceived affective cues as representing one source rather than two. (shrink)
Treating physicians have key roles to play in expanded access to investigational drugs, by identifying investigational treatment options, assessing the balance of risks and potential benefits, informing their patients, and applying to the regulatory authorities. This study is the first to explore physicians’ experiences and moral views, with the aim of understanding the conditions under which doctors decide to pursue expanded access for their patients and the obstacles and facilitators they encounter in the Netherlands. In this mixed-methods study, semi-structured interviews (...) and a questionnaire were conducted with medical specialists across the country and analysed thematically. Typically, our respondents pursue expanded access in “back against the wall” situations and broadly support its classic requirements. They indicate practical hurdles related to reimbursement, the amount of time and effort required for the application, and unfamiliarity with the regulatory process. Some physicians are morally opposed to expanded access, with an appeal to safety risks, lack of evidence, and “false hope.” Some of these moral concerns and practical obstacles may be essential targets for change, if expanded access to unapproved drugs is to become available for wider groups of patients for whom standard treatment options are not—or no longer—available, on a more consistent and equal basis.

We present a new axiomatization of the non-associative Lambek calculus. We prove that it takes polynomial time to reduce any non-associative Lambek categorial grammar to an equivalent context-free grammar. Since it is possible to recognize a sentence generated by a context-free grammar in polynomial time, this proves that a sentence generated by any non-associative Lambek categorial grammar can be recognized in polynomial time.

Thefarmers believe the welfare of their animals isgood, but, as frequent defensive utterancesshow, they feel uncomfortable with expressed orunexpressed accusations of mistreating animals.The ways the respondents deal with thisambivalence were analysed by drawing ontheories of dissonance reduction and distancing devices.

The present study investigated whether individual differences between psychologists in thinking styles are associated with accuracy in diagnostic classification. We asked novice and experienced clinicians to classify two clinical cases of clients with two co-occurring psychological disorders. No significant difference in diagnostic accuracy was found between the two groups, but when combining the data from novices and experienced psychologists accuracy was found to be negatively associated with certain decision making strategies and with a higher self-assessed ability and preference for a (...) rational thinking style. Our results underscore the idea that it might be fruitful to look for explanations of differences in the accuracy of diagnostic judgments in individual differences between psychologists (such as in thinking styles or decision making strategies used), rather than in experience level.

In this commentary, we point to guidelines for performing human neuroimaging studies and their reporting in microbiota-gut-brain articles. Moreover, we provide a view on interpretational issues in MGB studies, with a specific focus on gut microbiota–derived metabolites. Thus, extending the target article, we provide recommendations to the field to increase reproducibility and relevance of this type of MGB study.
Background Patients with unmet medical needs sometimes resort to non-standard treatment options, including the use of unapproved, investigational drugs in the context of clinical trials, compassionate use or named-patient programs. The views and experiences of patients with unmet medical needs regarding unapproved, investigational drugs have not yet been examined empirically. Methods In this qualitative study, exploratory interviews and focus groups were held with patients with chronic or life-threatening diseases, about topics related to non-standard treatment options, such as the search for (...) non-standard treatment options, patients’ views of the moral obligations of doctors, and the conditions under which they would or would not wish to use non-standard treatment options, including expanded access to unapproved, investigational drugs. Results Respondents had very little knowledge about and/or experience with existing opportunities for expanded access to investigational drugs, although some respondents were actively looking for non-standard treatment options. They had high expectations of their treating physicians, assuming them to be aware of non-standard treatment options, including clinical trials elsewhere and expanded access programs, and assuming that they would inform their patients about such options. Respondents carefully weighed the risks and potential benefits of pursuing expanded access, citing concerns related to the scientific evidence of the safety and efficacy of the drug, side effects, drug-drug interactions, and the maintaining of good quality of life. Respondents stressed the importance of education and assertiveness to obtain access to good-quality health care, and were willing to pay out of pocket for investigational drugs. Patients expressed concerns about equal access to new and/or non-standard treatment options. Conclusion When the end of a standard treatment trajectory comes into view, patients may prefer that treating physicians discuss non-standard treatment options with them, including opportunities for expanded access to unapproved, investigational drugs. Although our respondents had varying levels of understanding of expanded access programs, they seemed capable of making well-considered choices with regard to non-standard treatment options and had realistic expectations with regard to the safety and efficacy of such options. Dutch patients might be less likely to fall prey to false hope than often presumed. (shrink)
In the Lambek calculus of order 2 we allow only sequents in which the depth of nesting of implications is limited to 2. We prove that the decision problem of provability in the calculus can be solved in time polynomial in the length of the sequent. A normal form for proofs of second order sequents is defined. It is shown that for every proof there is a normal form proof with the same axioms. With this normal form we can give (...) an algorithm that decides provability of sequents in polynomial time.

This book brings together classic and recent papers in the philosophical and linguistic analysis of fuzzy grammar, gradience in meaning, word classes, and syntax. Issues such as how many grains make a heap, when a puddle becomes a pond, and so forth, have occupied thinkers since Aristotle and over the last two decades been the subject of increasing interest among linguists as well as in fields such as artificial intelligence and computational linguistics. The work is designed to be of use (...) to students in all these fields. It has a substantial introduction, is divided into thematic parts, contains annotated sections of further reading, and is fully indexed. (shrink)
The results of an empirical study into the perceptions of “hands-on” experts concerning the welfare of (non-human) animals in traveling circuses in the Netherlands are presented. A qualitative approach, based on in-depth conversations with trainers/performers, former trainers/performers, veterinarians, and an owner of an animal shelter, conveyed several patterns in the contextual construction of perceptions and the use of dissonance reduction strategies. Perceptions were analyzed with the help of the Symbolic Convergence Theory and the model of the frame of reference, consisting (...) of knowledge, convictions, values, norms, and interests. The study shows that the debate regarding animals in circuses in the Netherlands is centered on the level of welfare that is required; the importance of animal welfare is not disputed. Arguments that were used differed according to the respondents’ specific backgrounds and can be placed on a gradient ranging from the conviction that the welfare of animals in circuses is sufficiently warranted and both human and animal enjoy the performance (right end), to the conviction that animal welfare in circuses is negative, combined with the idea that the goal of entertaining people does not outweigh that (left end). The study confirms that perceptions reflect people’s contexts, though the variety in scopes suggests that the (inter)relations between people and their context are complex in nature. Evidence of cognitive dissonance was abundant. Coping strategies were found to be used more by respondents towards the right end of the gradient, suggesting that those respondents experience more ambivalence. This encountered pattern of association between position on the gradient and frequency of dissonance reduction strategies calls for further research on the type of ambivalent feelings experienced. The authors argue that, to come to an agreement about the welfare of animals in circuses, including the way this welfare should be guaranteed, stakeholders from different contexts need to engage in a dialogue in which a distance is taken from right/wrong-schemes and that starts from acceptance of dilemmas and ambiguity.

Often institutions or individuals are faced with decisions where not all claims can be satisfied. Sometimes, these claims will be of differing strength. In such cases, it must be decided whether or not weaker claims can be aggregated in order to collectively defeat stronger claims. Many are attracted to a view, which this chapter calls Limited Aggregation, where this is sometimes acceptable and sometimes not. A new version of this view, Local Relevance, has recently emerged. This chapter seeks to explore (...) and evaluate this view. In order to do so, the chapter offers a more precise interpretation of this basic approach, calling it ‘Sequential Claims-Matching’. The chapter shows how Sequential Claims-Matching avoids problems that dog other Limited Aggregation views but suffers from difficulties and ambiguities of its own. In particular, the chapter shows that it is hard to accommodate some core Limited Aggregation intuitions around tie-break cases within the Local Relevance view. (shrink)

Recent research suggests that one can have the feeling of being the cause of an action’s outcome, even in the absence of a prior intention to act. That is, experienced self-agency over behavior increases when outcome representations are primed outside of awareness, prior to executing the action and observing the resulting outcome. Based on the notion that behavior can be represented at different levels, we propose that priming outcome representations is more likely to augment self-agency experiences when the primed representation (...) corresponds with a person’s behavior representation level. Three experiments, using different priming and self-agency tasks, both measuring and manipulating the level of behavior representation, confirmed this idea. Priming high level outcome representations enhanced experienced self-agency over behavior more strongly when behavior was represented at a higher level, rather than a lower level. Thus, priming effects on self-agency experiences critically depend on behavior representation level. (shrink)
Experiences of having caused a certain outcome may arise from motor predictions based on action–outcome probabilities and causal inferences based on pre-activated outcome representations. However, when and how both indicators combine to affect such self-agency experiences is still unclear. Based on previous research on prediction and inference effects on self-agency, we propose that their contribution crucially depends on whether people have knowledge about the causal relation between actions and outcomes that is relevant to subsequent self-agency experiences. Therefore, we manipulated causal (...) knowledge that was either relevant or irrelevant by varying the probability of co-occurrence of specific actions and outcomes. Afterwards, we measured self-agency experiences in an action–outcome task where outcomes were primed or not. Results showed that motor prediction only affected self-agency when relevant actions and outcomes were learned to be causally related. Interestingly, however, inference effects also occurred when no relevant causal knowledge was acquired. (shrink)
The conscious awareness of voluntary action is associated with systematic changes in time perception: The interval between actions and outcomes is experienced as compressed in time. Although this temporal binding is thought to result from voluntary movement and provides a window to the sense of agency, recent studies challenge this idea by demonstrating binding in involuntary movement. We offer a potential account for these findings by proposing that binding between involuntary actions and effects can occur when self-causation is implied. Participants (...) made temporal judgements concerning a key press and a tone, while they learned to consider themselves as the cause of the effect or not. Results showed that implied self-causation increased temporal binding. Since intrinsic motor cues of movement were absent, these results suggest that sensory evidence about the key press caused binding in retrospect and in line with the participant’s sense of being an agent.
