Temporal Binding,Causation, and Agency: Developing a New Theoretical Framework

In temporal binding, the temporal interval between one event and another, occurring some time later, is subjectively compressed. We discuss two ways in which temporal binding has been conceptualized. In studies showing temporal binding between a voluntary action and its causal consequences, such binding is typically interpreted as providing a measure of an implicit or pre-reflective “sense of agency.” However, temporal binding has also been observed in contexts not involving voluntary action, but only the passive observation of a cause–effect sequence. In those contexts, it has been interpreted as a top-down effect on perception reflecting a belief in causality. These two views need not be in conflict with one another, if one thinks of them as concerning two separate mechanisms through which temporal binding can occur. In this paper, we explore an alternative possibility: that there is a unitary way of explaining temporal binding both within and outside the context of voluntary action as a top-down effect on perception reflecting a belief in causality. Any such explanation needs to account for ways in which agency, and factors connected with agency, has been shown to affect the strength of temporal binding. We show that principles of causal inference and causal selection already familiar from the literature on causal learning have the potential to explain why the strength of people's causal beliefs can be affected by the extent to which they are themselves actively involved in bringing about events, thus in turn affecting binding.     

Does sunshine prime loyal? Affective priming in the naming task

Recent work has found an affective priming effect using the naming task: In pronouncing target words, pronunciation latencies were consistently shorter when the target (e.g., loyal) was preceded by an evaluatively congruent (e.g., sunshine) rather than incongruent prime word (e.g, rain). Using the naming task, no affective priming was found in the present studies irrespective of prime-set size and target-set size (Experiment 1), irrespective of stimulus-onset asynchrony (Experiment 2), and even when a nearly exact replication of previous work that demonstrated the effect was conducted (Experiment 3). Finally, bilingual German/English speakers exhibited strong associative priming, but no affective priming, in both the English as well as the German language (Experiment 4). The results show that priming for evaluatively related words is not a general finding.     

Connection-Driven Inductive Theorem Proving

We present a method for integrating rippling-based rewriting into matrix-based theorem proving as a means for automating inductive specification proofs. The selection of connections in an inductive matrix proof is guided by symmetries between induction hypothesis and induction conclusion. Unification is extended by decision procedures and a rippling/reverse-rippling heuristic. Conditional substitutions are generated whenever a uniform substitution is impossible. We illustrate the integrated method by discussing several inductive proofs for the integer square root problem as well as the algorithms extracted from these proofs.     

Separation-individuation as a family transactional process in the transition to parenthood

This is a study of the impact of prebirth level of parental and marital individuation on the course of parent-infant and infant development during the first postnatal year. Support was found for the first hypothesis, namely, that a couple's composite individuation profile, taking into account the prebirth separation-individuation of the father and the mother, and their marriage, would be associated with positive infant development and parent-infant transactions related to separation-individuation and mutuality during the first postnatal year. A second hypothesis, that maternal individuation would most strongly predict infant and parent-infant development at 6 months, while paternal individuation would emerge at 1 year as a strong predictor, was not supported. It was found instead that prebirth maternal and paternal individuation were equally strong predictors at six months, while maternal individuation was the primary predictor at 12 months. Other findings on the direct and indirect associations between prebirth parental and marital individuation and postnatal parent-infant transactions suggest that early separation-individuation processes result from a complex configuration of triadic mother-father-infant transactions.     

Accuracy of confidence judgments: Stability and generality in the learning process and predictive validity for learning outcome

One aspect of metacognition is the monitoring of memory or comprehension measured with retrospective confidence judgments after test taking. The research questions of the present study were whether different measures for the accuracy of such confidence judgments are stable over learning time, whether they generalize over two different tests, and whether they predict the learning outcome. In order to answer these questions, a study was conducted in which university students (N = 113) learned about the basic concepts of operant conditioning for 30 min. Knowledge tests with confidence judgments presented after each item were obtained before learning, after 10 min, and at the end of the learning session. Bias and absolute bias were calculated as absolute measures of accuracy, and gamma, Pearson’s r, andd _a were calculated as relative measures of accuracy. The results showed that the absolute measures were stable, but that the relative measures were not. Furthermore, absolute bias, gamma, and Pearson’s r obtained 10 min after the beginning of the learning process predicted the learning outcome. The results are discussed with regard to research on different measures of accuracy for confidence judgments.     

The role of occlusion cues in apparent motion

Classical apparent motion stimuli exhibit an inherent ambiguity with respect to the onsets and offsets of the stimulus elements. Sigman and Rock (1974, Perception 3 9-28) presented evidence suggesting that occlusion cues are used to resolve this ambiguity. We present results from experiments designed to further test predictions of this hypothesis. As expected, we found that the apparent motion of a target stimulus is suppressed when a 'moving' occluder is positioned such that it rationalises the onsets and offsets of the stimulus elements constituting the target. Somewhat unexpectedly, though, we also observed a slight tendency for motion suppression under conditions where the target was only partially occluded. The expected motion suppression occurred both with solid occluders and purely virtual Kanizsa-like occluders, although it was not always observed in the latter case. Motion suppression was found to occur over a wide range of stimulus onset asynchronies. Finally, we used binocular disparity cues to test the occlusion account of the motion suppression phenomenon against an alternative explanation in terms of attentional factors. The results are in clear favour of the occlusion account.     

Ressourcenaktivierung bei Patienten

Background

Starting from Klaus Grawe’s draft of a general psychotherapy, the patient’s resources and resource-activating interventions have received increasing attention in empirical research.

Objective

The effectiveness of standardized writing instructions for the activation of patients’ resources before participating in internet chat aftercare groups for psychosomatic patients was examined.

Method

In a randomized controlled trial writing instruction for the activation of patients’ resources was given in 52 out of 102 internet chat aftercare sessions. The effects of this minimal intervention on the patients’ activity and the number of positive emotion words expressed during the chat session were examined. Additionally, the effects on patients’ self-esteem, attachment, orientation, control and well-being after the group sessions were assessed.

Results

Patients reported higher levels of self-esteem, orientation, control and well-being after chat sessions with a resource-activating intervention. No differences between intervention and control groups were detected on the text-based variables activity and number of positive emotion words.

Conclusions

Standardized minimal interventions for the activation of patients’ resources seem to be promising for enhancing the effectiveness of therapeutic Internet chat groups.     

Moral Desirability and Rational Decision

Being a formal and general as well as the most widely accepted approach to practical rationality, rational decision theory should be crucial for justifying rational morals. In particular, acting morally should also (nearly always) be rational in decision theoretic terms. After defending this thesis, in the critical part of the paper two strategies to develop morals following this insight are criticized: game theoretical ethics of cooperation and ethical intuitionism. The central structural objections to ethics of cooperation are that they too directly aim at the rationality of moral action and that they to do not encompass moral values or a moral desirability function. The constructive half of the paper takes up these criticisms by developing a two-part strategy to bring rationality and morals in line. The first part is to define ‘moral desirability’. This is done, using multi-attribute utility theory, by equating several adequate components of an individual’s comprehensive (rational) utility function with the moral desirability function. The second part is to introduce mechanisms, institutions, in particular socially valid moral norms, that provide further motivation for acting in accordance with morals.
