Choosing in freedom or forced to choose? Introspective blindness to psychological forcing in stage-magic.

ABSTRACT: We investigated an individual ability to identify whether choices were made freely or forced by external parameters. We capitalized on magical setups where the notion of psychological forcing constitutes a well trodden path. In live stage magic, a magician guessed cards from spectators while inquiring how freely they thought they had made the choice. Our data showed a marked blindness in the introspection of free choice. Spectators assigned comparable ratings when choosing the card that the magician deliberately forced them compared to any other card, even in classical forcing, where the magician literally handles a card to the participant This observation was paralleled by a laboratory experiment where we observed modest changes in subjective reports by factors with drastic effect in choice. Pupil dilatation, which is known to tag slow cognitive events related to memory and attention, constitutes an efficient fingerprint to index subjective and objective aspects of choice.

Project description:BackgroundPeople with dementia living in nursing homes are mostly sedentary, which is a consequence of various personal, environmental and organizational factors. Until now, studies on physical activity and safety in dementia have focused on residents and caregivers from the viewpoint of (individual) care provision and health benefits. There has been little to no focus on the possible influence of group dynamics between care providers with regard to physical activity and safety. The aim of this study is to gain more insight into the viewpoints and intentions of groups of professional caregivers towards safety and physical activity and the potential influence of the group-oriented setting in long-term care on physical activity of individual residents.MethodsA qualitative study comprising three focus group discussions including professional caregivers (n = 15) was conducted within two long-term care organizations in the Netherlands. Focus group discussions were structured using an interview guide derived from a preliminary framework, based on existing literature and complemented with clinical expertise.ResultsSeven themes could be derived from the focus group discussions that influence physical activity and safety: 1) Individual health and abilities; 2) Balancing physical activity and safety; 3) Physical restraints; 4) Group interests versus the individual interests; 5) Organization of care and physical environment; 6) Perceived responsibilities and tasks of professional caregivers and 7) Change is challenging.ConclusionsDue to multiple influencing factors, the balance for care providers in long-term care generally tends towards safety over physical activity. Furthermore, in order to stimulate physical activity various limitations are experienced, including the organization of care, the general health of the residents and difficulty to achieve changes in daily care. Most importantly, the group interests of both the professional caregivers and the residents have a substantial influence on the incorporation of physical activity in daily care.

Project description:For more than 60 years, it has been known that people report higher (lower) subjective values for items after having selected (rejected) them during a choice task. This phenomenon is coined "choice-induced preference change" or CIPC, and its established interpretation is that of "cognitive dissonance" theory. In brief, if people feel uneasy about their choice, they later convince themselves, albeit not always consciously, that the chosen (rejected) item was actually better (worse) than they had originally estimated. While this might make sense from an intuitive psychological standpoint, it is challenging from a theoretical evolutionary perspective. This is because such a cognitive mechanism might yield irrational biases, whose adaptive fitness would be unclear. In this work, we consider an alternative possibility, namely that CIPC is -at least partially- due to the refinement of option value representations that occurs while people are pondering about choice options. For example, contemplating competing possibilities during a choice may highlight aspects of the alternative options that were not considered before. In the context of difficult decisions, this would enable people to reassess option values until they reach a satisfactory level of confidence. This makes CIPC the epiphenomenal outcome of a cognitive process that is instrumental to the decision. Critically, our hypothesis implies novel predictions about how observed CIPC should relate to two specific meta-cognitive processes, namely: choice confidence and subjective certainty regarding pre-choice value judgments. We test these predictions in a behavioral experiment where participants rate the subjective value of food items both before and after choosing between equally valued items; we augment this traditional design with both reports of choice confidence and subjective certainty about value judgments. The results confirm our predictions and provide evidence that many quantitative features of CIPC (in particular: its relationship with metacognitive judgments) may be explained without ever invoking post-choice cognitive dissonance reduction explanation. We then discuss the relevance of our work in the context of the existing debate regarding the putative cognitive mechanisms underlying CIPC.
