Fitch’s paradox and <Emphasis Type="Italic">ceteris paribus</Emphasis> modalities

The paper attempts to give a solution to the Fitch’s paradox though the strategy of the reformulation of the paradox in temporal logic, and a notion of knowledge which is a kind of ceteris paribus modality. An analogous solution has been offered in a different context to solve the problem of metaphysical determinism.     

Kant on the Inapplicability of the Categories to Things in Themselves

This paper addresses the question of what we can legitimately say about things in themselves in Kant's critical doctrine. Many Kant scholars believe that Kant allows that things in themselves can be characterized through the unschematized or ‘pure’ concepts of our understanding such as ‘substance’ or ‘causality’. However, I show that on Kant's view things in themselves do not conform to the unschematized categories (given their standard discursive meaning): the pure categories, like space and time, are merely subjective forms of finite, discursive cognition. I then examine what this interpretation might entail for central aspects of Kant's system such as his doctrine of noumenal freedom.     

SARA: A cognitive process model to simulate the anchoring effect and hindsight bias

The cognitive process model "SARA" aims to explain the anchoring effect and hindsight bias by making detailed assumptions about the representation and alteration of item-specific knowledge. The model assumes that all processes, namely generating an estimate, encoding new information (i.e., the "anchor"), and reconstructing a previously generated estimate, are based on a probabilistic sampling process. Sampling probes long-term memory in order to retrieve information into working memory. Retrieval depends on the associative strength between this information and the currently active retrieval cues. Encoding the anchor may alter this associative pattern ("selective activation") or the anchor may serve as a retrieval cue, thus directing memory search ("biased reconstruction"). Both processes lead to systematically changed retrieval probabilities, thus causing the anchoring effect or hindsight bias. The model is completely formalised and implemented as a computer program. A series of simulations demonstrates the power of SARA to reproduce empirical findings and to predict new ones.     

A novel study: Investigating the structure of narrative and autobiographical memories

In two experiments we assessed the degree to which memory for events are similar or differ depending on whether they were narrative or autobiographical events. Consistent with previous research on autobiographical memory, memories for events captured the sequential order of events. However, in contrast to autobiographical memory research, ratings of importance did not appear to be related to retrieval speed. An analysis of causal connectivity of the recalled events was significantly related to retrieval speed. Issues of narrative comprehension and memory, autobiographical memory, and their overlap are discussed.     

Perceptual Judgments of Sports Officials are Influenced by their Motor and Visual Experience

We examined the relation between previous motor and visual experience and current officiating experience of expert judges and referees and their judgments from an embodied cognition viewpoint. A total of 370 sports officials from soccer, handball, ice hockey, and trampoline took part in the study. Analyses revealed that cognitive judgments are related to motor, visual, and officiating experience to different degrees in the analyzed sports. Our findings indicate that, depending on the sport, sports officials should either specialize early in officiating, or gather visuo-motor experience as an athlete or spectator first, and then switch roles to become a sports official.     

A goal model of catharsis

Although research in social psychology has repeatedly refuted the idea that aggression reduces subsequent aggression (e.g., Bushman, 2002), we suggest a more fine-grained analysis of catharsis. We will present and discuss a social-cognitive goal model of cathartic effects in aggression that predicts under which conditions aggression increases or reduces subsequent aggression. The model assumes that the accessibility of aggression-related constructs is a function of goal fulfilment: Prior to goal fulfilment constructs related to the goal are highly accessible in order to facilitate goal fulfilment. However, after goal fulfilment this heightened accessibility loses its functionality and aggressive constructs are consequently inhibited. In the present article we will review empirical work testing this model. Moreover, we will extend this model to the effects of violent computer games. Finally we will discuss theoretical challenges and applied relevance of our model for intervention strategies aimed at reducing aggression.     

Feeling close and doing well: The prevalence and motivational effects of interpersonally engaging emotions in Mexican and European American cultural contexts

Two studies investigate whether interpersonally engaging emotions—those that bring the self closer to others (e.g., affection, shame)—are central to the model of self and relationships prevalent in Mexican cultural contexts. Study 1 demonstrated that compared to people in European American contexts, people in Mexican contexts were more likely to report experiencing interpersonally engaging emotions and less likely to report experiencing interpersonally disengaging emotions. Study 2 found that interpersonally engaging emotions had a substantial influence on performance motivation in Mexican contexts—Mexican participants solved more word search puzzles after recalling instances in which they experienced positive interpersonally engaging emotions, and fewer after recalling negative interpersonally disengaging emotions; in contrast, there were no differences by condition for European Americans. These findings significantly extend previous research by documenting the implications of relational concerns (e.g., simpatia, personalismo) for emotion and motivation in Mexican contexts, and are the first to demonstrate the motivational effects of interpersonally engaging emotions.     

Adaptation in Visuomanual Tracking Depends on Intact Proprioception

The role of arm proprioception in motor learning was investigated in experiments in which, by moving the arm, subjects followed the motion of a target displayed on a monitor screen. Adaptive capabilities were tested in visuomanual tracking tasks following alterations in the relationship between the observer's actual arm movement and visual feedback of the arm movement given by a cursor motion on the screen. Tracking performance and adaptive changes, measured in terms of spatiotemporal error, tracking trajectory curvature, and spatial gain, were compared in 7 control subjects (CSs) and in 1 deafferented subject (DS). CSs adapted appropriately to altered visuomanual relationships; those changes were present in trials immediately after restoration of normal scaling. In contrast, although the DS modified his tracking strategy from trial to trial according to the altered conditions, he did not show plastic changes in internal visuomanual scaling. Like the results of prismatic adaptation experiments, the present results suggest that arm proprioception contributes to the plastic changes that follow alterations in the scaling of visuomanual gain.     

A Short Measure of the Need for Affect

Summary

Widespread divergencies of opinion exist over the usefulness, the nature, the purpose, and the scientific status of clinical psychological testing. This paper seeks to order these problems in historical and philosophical perspective. Largely different values and orientations have been contributed by traditional American academic psychology, by clinical psychology, and by psychiatry. Academic psychologists advocate a rigorous scientific basis (logical positivism) for testing, which the clinician tends to find overly confining and antagonistic to his humanistic, individual centered, service orientation; while psychiatrists tend to differ greatly among themselves in their understanding of psychological testing and hence exert no uniform influence on the practice. The current trend emphasizes greater sophistication in the academic approach to testing, with advances in empiricism and computer-aided manipulation of data, while the more clinically oriented psychologists seek to strengthen their theoretical position and to demonstrate the effectiveness of their methods through studies of clinical judgment. At the same time basic methodological research to support the “clinical position” is yet too sparse. It is proposed that both academic and clinical approaches have a significant contribution to make to clinical psychological testing. Ultimately the design of psychological tests and the evaluation of their usefulness rests upon what we conceive psychological science to be, and we need to remind ourselves, in this regard, that the conception of science is subject to change.     

Pacifiers Disrupt Adults’ Responses to Infants’ Emotions

Research shows that pacifiers disrupt infants' mimicry of facial expressions. This experiment examines whether pacifiers interfere with caretakers' ability to mimic infants' emotions. Adults saw photographs of infants with or without a pacifier. When infants had pacifiers, perceivers showed reduced EMG activity to infants' smiles. Smiles of infants using a pacifier were also rated as less happy than smiles depicted without a pacifier. The same pattern was observed for expressions of distress: adults rated infants presented with pacifiers as less sad than infants without pacifiers. We discuss deleterious effects of pacifier use for the perceiver's resonance with a child's emotions.
