Spreading the blame: The allocation of responsibility amongst multiple agents

How do people assign responsibility to individuals in a group context? Participants played a repeated trial experimental game with three computer players, in which they counted triangles presented in complex diagrams. Three between-subject conditions differed in how the group outcome was computed from the individual players’ answers. After each round, participants assigned responsibility for the outcome to each player. The results showed that participants’ assignments varied between conditions, and were sensitive to the function that translated individual contributions into the group outcome. The predictions of different cognitive models of attribution were tested, and the Structural Model (Chockler & Halpern, 2004) predicted the data best.     

Konflikt- und Strukturachse der Operationalisierten Psychodynamischen Diagnostik des Kindes- und Jugendalters

This paper presents the advantages of a comprehensive Operationalized Psychodynamic Diagnostic in childhood and adolescence (OPD-CA) for subsequent treatment planning. Information about the conflict and structural axes as a function of age, gender, diagnosis and proposed form of treatment (outpatient/inpatient) was analyzed in a group of 116 patients. Independent from the diagnosis, a similar ranking in the importance of conflicts was found. Self-esteem conflicts were more prominent for inpatient children and adolescents and identity conflicts were more prevalent in children and adolescents who were at the start of outpatient therapy. Patients with an indication for inpatient treatment had a significantly lower level in all structural dimensions. This study analyzes the reasons for these findings.     

Associative symmetry versus independent associations in the memory for object-location associations

The formation of associations between objects and locations is a vital aspect of episodic memory. More specifically, remembering the location where one experienced an object and, vice versa, the object one encountered at a specific location are both important elements for the memory of an event. Whether episodic associations are holistic representations of individual components or whether there are unidirectional, separately modifiable connections between them has been investigated nearly exclusively using verbal stimuli. A preliminary conclusion concerning this controversy is that verbal associations are, at least, highly correlated (M. J. Kahana, 2002). This theoretical debate, which in the past has undergone a major empirical effort, is still of relevance for the concurrent global matching models of associative memory (S. E. Clark & S. D. Gronlund, 1996). The authors used variations of a novel object-location learning paradigm to complement the accumulated evidence regarding the nature of episodic associations.     

The importance of response type to the relationship between temporal order and numerical magnitude

Time, number, and space may be represented in the brain by a common set of cognitive/neural mechanisms. In support of this conjecture, Schwarz and Eiselt (Journal of Experimental Psychology: Human Perception and Performance, 35, 989-1004, 2009) found that numerically smaller digits were perceived to occur earlier than larger digits, and they concluded that this difference reflected faster processing of smaller numbers. This difference, however, could have been related to a response bias, whereby participants map responses of "which first" onto the "first" number along the mental number line. In Experiment 1, participants made temporal order judgements between digits presented to the left or to the right. The point of subjective simultaneity was shifted so that the 9 had to be presented before the 2 in order for simultaneity to be perceived. This difference could reflect either faster processing of the 2 or a response bias. Experiments 2a and 2b eliminated response biases by using simultaneity judgements, which have no logical stimulus mapping. Both of the latter experiments established that the 2 was not processed faster than the 9. Although the present results relate specifically to numerical magnitude and temporal order associations, they also have broader implications. Other studies have reported associations between dimensions such as size, duration, and number and have attributed these to parietal mechanisms. Such associations, however, may also be an artefact of response biases.
