Biased information processing in the escalation paradigm: information search and information evaluation as potential mediators of escalating commitment

Escalation of commitment denotes decision makers' increased reinvestment of resources in a losing course of action. Despite the relevance of this topic, little is known about how information is processed in escalation situations, that is, whether decision makers who receive negative outcome feedback on their initial decision search for and/or process information biasedly and whether these biases contribute to escalating commitment. Contrary to a widely cited study by E. J. Conlon and J. M. Parks (1987), in 3 experiments, the authors found that biases do not occur on the level of information search. Neither in a direct replication and extension of the original study with largely increased test power (Experiment 1) nor under methodologically improved conditions (Experiments 2 and 3) did decision makers responsible for failure differ from nonresponsible decision makers with regards to information search, and no selective search for information supporting the initial decision or voting for further reinvestment was observed. However, Experiments 3 and 4 show that the evaluation of the previously sought information is biased among participants who were responsible for initiating the course of action. Mediation analyses show that this evaluation bias in favor of reinvestment partially mediated the responsibility effect on escalation of commitment.     

The nonverbal manifestations of cognitive processes in clinical listening

Nonverbal behaviors were observed during communicative sequences in videotaped clinical interviews. The interviews were conducted by two groups of physicians-in-training with contrasting cognitive profiles as determined by well-known laboratory tasks prior to the interviews. In each phase of the communicative sequences, significant differences emerged between the two groups for various types of nonverbal behaviors. Differences also emerged between the two groups of interviewers in their questioning patterns and in the nature of the narrative elicited from their interlocutors. A correlational analysis revealed consistent patterns of behaviors across phases of the communicative sequences. The findings provide additional evidence for the intimate connection between nonverbal behavior and cognitive activity and point to nonverbal behaviors as objective measures of the processes underlying clinical listening.     

The language of landmarks: the role of background knowledge in indoor wayfinding

To effectively wayfind through unfamiliar buildings, humans infer their relative position to target locations not only by interpreting geometric layouts, especially length of line of sight, but also by using background knowledge to evaluate landmarks with respect to their probable spatial relation to a target. Questionnaire results revealed that participants have consistent background knowledge about the relative position of target locations. Landmarks were rated significantly differently with respect to their spatial relation to targets. In addition, results from a forced-choice task comparing snapshots of a virtual environment revealed that background knowledge influenced wayfinding decisions. We suggest that landmarks are interpreted semantically with respect to their function and spatial relation to the target location and thereby influence wayfinding decisions. This indicates that background knowledge plays a role in wayfinding.     

TripleR: An R package for social relations analyses based on round-robin designs

In this article, we present TripleR, an R package for the calculation of social relations analyses (Kenny, 1994) based on round-robin designs. The scope of existing software solutions is ported to R and enhanced with previously unimplemented methods of significance testing in single groups (Lashley & Bond, 1997) and handling of missing values. The package requires only minimal knowledge of R, and results can be exported for subsequent analyses to other software packages. We demonstrate the use of TripleR with several didactic examples.     

Error detection and error memory in spatial navigation as reflected by electrodermal activity

The study investigated spatial navigation by means of electrodermal activity (EDA). Two groups of healthy subjects (group 1, age <38; group 2, age ≥38) were recorded during navigation through two 3-D virtual mazes differing in difficulty, that is, Maze Simple (MazeS) and Maze Complex (MazeC). Our results show (1) an effect of difficulty, that is, larger skin conductance responses (SCRs) and slower velocity profiles while navigating through MazeC as compared to MazeS. (2) An effect of age, that is, larger SCRs and faster velocity profiles in younger subjects (group 1) compared to older subjects (group 2). (3) An effect of maze region, that is, SCRs increased when subjects entered dead ends with group 1 (young group) decreasing in velocity, whereas group 2 (old group) increased in velocity. (4) And an error memory effect, that is, subjects who remembered an error at a given decision point (crossroads preceding dead ends in MazeC) from previous trials, and then if they did not repeat that error, elicited decreased SCRs as compared to subjects who did not remember and subsequently repeated an error. The latter aspect is the most impactful as it shows that EDA is able to reflect error detection and memory during spatial navigation. Our data designate EDA as suitable monitoring tool for identification and differentiation of the affective correlates underlying spatial navigation, which has recently attracted researchers’ attention due to its increased use in 3-D virtual environments.     

Der Foto-Hand-Test

Projective psychological techniques might be useful for measuring forensically relevant constructs in the context of a multimodal assessment strategy but are often considered to be deficient concerning reliability and validity. The Photo Hand Test (FHT), a German version of the Hand Test, is a diagnostic tool aimed at measuring aggressive dispositions. It uses photographs of hand gestures which test persons are required to interpret. The answers are coded and an acting-out score is computed from diverse categories.A study on the reliability and validity of the FHT protocols from 98 offenders and a comparison group of 55 non-offenders was carried out. Internal consistency coefficients of the FHT scores were low and unsatisfactory. Offenders had higher acting-out scores than non-offenders, they did not give more aggression-prone interpretations but more interpretations coded as aggression-inhibiting. Correlations of the FHT scores with self-report scales from the Antisocial Personality Questionnaire did not show the expected patterns; however, they did suggest effects of a hostility bias: persons who interpreted many hand gestures as aggression-prone did not describe themselves as highly aggressive or impulsive but were more distrustful and paranoid. This indicates a projection mechanism different from the one postulated by the FHT authors.The results suggest that FHT measures should be interpreted with caution in forensic evaluations.
