Is coherence conducive to reliability?

A measure of coherence is said to be reliability conducive if and only if a higher degree of coherence (as measured) of a set of testimonies implies a higher probability that the witnesses are reliable. Recently, it has been proved that the Shogenji measure of coherence is reliability conducive in restricted scenarios (e.g., Olsson and Schubert, Synthese, 157:297?C308, 2007). In this article, I investigate whether the Shogenji measure, or any other coherence measure, is reliability conducive in general. An impossibility theorem is proved to the effect that this is not the case. I conclude that coherence is not reliability conducive.     

When different means bad or merely worse. How minimal and maximal goals affect ingroup projection and outgroup attitudes

Group members tend to perceive their ingroup relative to an outgroup as more prototypical for a common superordinate group because they project features of their ingroup onto the superordinate group. As a consequence, the ingroup is perceived as more positive than the outgroup (Mummendey & Wenzel, 1999). We extend the ingroup projection model by examining different types of ingroup goals: minimal and maximal goals as well as actual and ideal goals. Minimal goals should engender either‐or thinking and lead to more ingroup projection compared with maximal goals that should involve more nuanced thinking. Ingroup prototypicality in terms of ideal goals (e.g., what we ideally should strive for) was expected to show a stronger relation to outgroup attitudes than ingroup prototypicality in terms of actual goals (e.g., what we are actually striving for). We manipulated minimal and maximal goal orientation and assessed actual and ideal goals. Across two studies, relative ingroup prototypicality was higher in the minimal compared with the maximal goal condition. Moreover, ingroup prototypicality referring to ideal goals showed a stronger relation to outgroup evaluation than ingroup prototypicality referring to actual goals.

Tracking cognitive phases in analogical reasoning with event-related potentials

Analogical reasoning consists of multiple phases. Four-term analogies (A:B::C:D) have an encoding period in which the A:B pair is evaluated prior to a mapping phase. The electrophysiological timing associated with analogical reasoning has remained unclear. We used event-related potentials to identify neural timing related to analogical reasoning relative to perceptual and semantic control conditions. Spatiotemporal principal-components analyses revealed differences primarily in left frontal electrodes during encoding and mapping phases of analogies relative to the other conditions. The timing of the activity differed depending upon the phase of the problem. During the encoding of A:B terms, analogies elicited a positive deflection compared to the control conditions between 400 and 1,200 ms, but for the mapping phase analogical processing elicited a negative deflection that occurred earlier and for a shorter time period, between 350 and 625 ms. These results provide neural and behavioral evidence that 4-term analogy problems involve a highly active evaluation phase of the A:B pair.     

The time course of temporal attention effects on nonconscious prime processing

We presented a masked prime at various prime–target intervals (PTIs) before a target that required a speeded motor response and investigated the impact of temporal attention on the nonconscious prime processing. The allocation of temporal attention to the target was manipulated by presenting an accessory tone and comparing that condition with a no-tone condition. The results showed that, independently of the visibility of the prime, temporal attention led to an enhanced effect of prime–target congruency on the reaction times, and that the amount of the enhancement increased with increasing PTIs. This effect pattern is consistent with the assumption of increasing influences of temporal attention and of the increasing PTI on nonconscious prime processing; it argues against the hypothesis that temporal attention narrows the time period in which the prime may affect target processing. An accumulator model is proposed assuming that target-related temporal attention increases the accumulation rate for masked primes and, thus, enhances the impact of the prime on the speed of choice decisions.     

Warm and touching tears: tearful individuals are perceived as warmer because we assume they feel moved and touched

ABSTRACT

Recent work investigated the inter-individual functions of emotional tears in depth. In one study (Van de Ven, N., Meijs, M. H. J., & Vingerhoets, A. (2017). What emotional tears convey: Tearful individuals are seen as warmer, but also as less competent. British Journal of Social Psychology, 56(1), 146–160. Https://doi.org/10.1111/bjso.12162) tearful individuals were rated as warmer, and participants expressed more intentions to approach and help such individuals. Simultaneously, tearful individuals were rated as less competent, and participants expressed less intention to work with the depicted targets. While tearful individuals were perceived as sadder, perceived sadness mediated only the effect on competence, but not on warmth. We argue that tearful individuals might be perceived as warm because they are perceived as feeling moved and touched. We ran a pre-registered extended replication of Van de Ven et al. Results replicate the warmth and helping findings, but not the competence and work effects. The increase in warmth ratings was completely mediated by perceiving feeling moved and touched. Possible functions of feeling moved and touched with regard to emotional tears are discussed.     

Working memory demands modulate cognitive control in the Stroop paradigm

One important task of cognitive control is to regulate behavior by resolving information processing conflicts. In the Stroop task, e.g., incongruent trials lead to conflict-related enhancements of cognitive control and to improved behavioral performance in subsequent trials. Several studies suggested that these cognitive control processes are functionally and anatomically related to working memory (WM) functions. The present study investigated this suggestion and tested whether these control processes are modulated by concurrent WM demands. For this purpose, we performed three experiments in which we combined different WM tasks with the Stroop paradigm and measured their effects on cognitive control. We found that high WM demands led to a suppression of conflict-triggered cognitive control, whereas our findings suggest that this suppression effect is rather due to WM updating than to maintenance demands. We explain our findings by assuming that WM processes interfere with conflict-triggered cognitive control, harming the efficiency of these control processes.     

Effects of Practice upon the Metabolic Cost of Mental Work

Two experiments with isopods, Armadillidium vulgare, were reported. In Experiment I, two groups of five Ss each learned to run a T maze to escape light and heat. Both original learning (OL), and relearning (RL) the next day, were to a criterion 9/10 correct. Between OL and RL one group was immobilized (I), and the other group was given the opportunity for activity (A). The I treatment resulted in greater savings on RL than did the A treatment, and it was thus concluded that A is a retroaction treatment. Experiment II was like I except that all Ss were extinguished immediately following OL, and then given either A or I until RL. In this experiment, the A treatment led to no savings, but the I treatment produced negative savings (more trials on RL relative to OL). It was concluded that the A treatment had retroactively interfered with extinction, and this result was discussed as analogous to differential spontaneous recovery in favor of the A group. It was concluded that Liberman's (4, 5) theory (that spontaneous recovery is due to the forgetting of extinction) is supported by the result of Experiment II.     

Dreidimensionales Körperbild in der Psychodiagnostik

The body sculpture technique is a procedure in which patients create a three-dimensional model of their own body with modelling clay. This existing technique has been further developed into the modular body sculpture technique and offers a diagnostic approach to the body image. After an introduction in the conceptual foundations of body self-representation the technique is described. Using a case study, advantages for clinical applications are illustrated. Contributions of this technique to a deeper understanding of the structure of body memory are discussed in the context of current cognitive theories.     

Affective responses to abuse in the workplace: The role of hope and affective commitment

Affective responses constitute the mechanism by which abusive supervision received is associated with subordinates’ turnover intentions. Using affective events theory (AET) as a theoretical framework, we suggest that abusive supervision is a contextual event that is associated with subordinates’ affective reactions and corresponding evaluative judgment of their workplace, which ultimately leads to increased turnover intentions, a prominent withdrawal outcome. We examine two affective responses as mediators, hope (a goal-related affective state based on the expectation of positive outcomes) and affective commitment (affect-based evaluation of the organization). Two samples from a field study (n = 209) and an experiment (n = 427) were analyzed using structural equation modeling. Results supported our proposed chain of relationships, suggesting that subordinates are likely to experience decreased hope and affective commitment after having experienced abuse from a supervisor, which subsequently impact their withdrawal intention to leave the organization.
