Emergence in physics

In this paper we intend to examine whether there are examples for emergence to be found in physics. The answer depends on the concept of emergence one invokes. We distinguish two such concepts, those of Broad and Kim. We will argue that it is unlikely that there will be examples with respect to the former because it runs counter to an explanatory strategy that is both well entrenched in physical practice and to a certain degree flexible. On the other hand we will argue that all those physical systems that provide an example for supervenience are at the same time examples for emergence - at least if one defines emergence the way Kim does.     

Altruism in adolescents and young adults: validation of an instrument to measure generative altruism with structural equation modeling

Aim of this study was to develop and test a research instrument to measure generative and functional altruism in adolescents/young adults. In an anonymous questionnaire survey using standardised questionnaires, 873 students were recruited in academic high schools and professional schools. The 7-item Generative Altruism Scale (GALS), which includes affective and behavioural elements, correlated with relevant external measures that correspond with the underlying construct. Confirmatory factor analysis proved an acceptable model fit with characteristics of χ² [df = 14, N = 846] = 129.946, p < .001, CFI = .91, AIC = 157.946, and SRMR = .048. Female and male students differed significantly with respect to altruism scores (F = 25.5; p < .0001). The GALS could be used for empirical studies analysing the connection between altruism and the development of ethical values and prosocial behaviour. Particularly, compassion as an intrinsic motivator could be fostered in appropriate education programmes.     

Normalizing the Supernormal: The Formation of the “Gesellschaft Für Psychologische Forschung” (“Society for Psychological Research”), c. 1886–1890

This paper traces the formation of the German “Gesellschaft für psychologische Forschung” (“Society for Psychological Research”), whose constitutive branches in Munich and Berlin were originally founded as inlets for alternatives to Wundtian experimental psychology from France and England, that is, experimental researches into hypnotism and alleged supernormal phenomena. By utilizing the career trajectories of Max Dessoir and Albert von Schrenck‐Notzing as founding members of the “Gesellschaft,” this paper aims to open up novel perspectives regarding extra‐scientific factors involved in historically determining the epistemological and methodological boundaries of nascent psychology in Germany.     

Reasoning and normative beliefs: not too sophisticated

Does reasoning to a certain conclusion necessarily involve a normative belief in support of that conclusion? In many recent discussions of the nature of reasoning, such a normative belief condition is rejected. One main objection is that it requires too much conceptual sophistication and thereby excludes certain reasoners, such as small children. I argue that this objection is mistaken. Its advocates overestimate what is necessary for grasping the normative concepts required by the condition, while seriously underestimating the importance of such concepts for our most fundamental agential capacities. Underlying the objection is the observation that normative thoughts do not necessarily cross our minds during reasoning. I show that proponents of the normative belief condition can accommodate this observation by taking the required normative belief to guide the reasoning process and offer a novel account of what such guidance consists in.     

Politics perceptions as moderator of the political skill – job performance relationship: A two-study, cross-national, constructive replication

We developed a two-study, cross-national, constructive replication to examine the role of organizational politics perceptions as a contextual moderator of the political skill – job performance relationship. Specifically, we hypothesized that high levels of political skill would demonstrate its strongest positive effects on job performance when politics perceptions were perceived as low. Conversely, we hypothesized that political skill would demonstrate no relationship with job performance under conditions of high politics perceptions. Across studies conducted both in the United States and Greece, the hypothesis received strong support. In settings characterized by lower perceived politics, high levels of political skill predicted significant increases in job performance, whereas these effects were attenuated in environments characterized by high perceived politics. Contributions and implications of this research, strengths and limitations, and directions for future study are discussed.     

Imitation of Gestures in Children is Goal-directed

The view that the motor program activated during imitation is organized by goals was investigated by asking pre-school children to imitate a set of hand gestures of varying complexity that were made by an experimenter sitting in front of them. In Experiments 1 and 3, children reached for the correct object (one of their own ears or one of two dots on a table) but preferred to use the ipsilateral hand. This ipsilateral preference was not observed when hand movements were made to only one ear (Experiment 2), or when movements were diercted at space rather than physical objects (Experiment 3). The results are consistent with the notion that imitation is guided by goals and provide insights about how these goals are organized.     

Attractors and perceptual field dynamics of homogeneous stimulus areas

Summary The phenomenon of the wandering point on a blank sheet of paper in serial reproductions is the starting point of an investigation of the perceptual field structure of homogeneous stimulus areas; 609 stimulus points distributed regularly in 21 rows and 29 columns on a DIN A4 sheet were presented successively to 10 subjects and had to be reproduced immediately afterwards in order to establish empirical vector fields. These were subjected to vector-analytic procedures. A method for the decomposition of the measured vector fields into partitions from gradient potentials and circulation potentials is demonstrated. The gradient potentials of the empirical vector fields revealed a highly regular structure with four point attractors near the corners of the sheet. A model calculation of the wandering point in this potential landscape showed results comparable to the empirical phenomenon. The results are discussed in favor of Gestalt theory and against direct perception.     

An unobtrusive measurement method of the horizontal gaze angle

A horizontal gaze angle measurement device is introduced. By combining a photoelectric viewing device to measure the horizontal eye angle with a similar head angle measurement device, it is possible to measure the horizontal gaze angle without using a headrest. After discussion of circuit diagrams and measurement principles, it is shown that the measurements made with the device yield a reasonable precision. The mean absolute measurement error is below 1°. This inexpensive and unobtrusive device covers a visual field of about 20° and can be used in parallel with many tasks. Further, data on the successful application of the device in a driving simulation setting are discussed.
