Infrahumanization or familiarity? Attribution of uniquely human emotions to the self, the ingroup, and the outgroup

People attribute more secondary emotions to their ingroup than to outgroups. This effect is interpreted in terms of infrahumanization theory. Familiarity also could explain this differential attribution because secondary emotions are thought to be less visible and intense than primary ones. This alternative explanation to infrahumanization was tested in three studies. In Study 1, participants attributed, in a between-participants design, primary and secondary emotions to themselves, to their ingroup, or to an outgroup. In Study 2, participants answered for themselves and their ingroup or for themselves and an outgroup. In Study 3, participants made attributions to the ingroup or a series of outgroups varying in terms of familiarity. The data do not support an explanation in terms of familiarity. The discussion centers on conditions not conducting to infrahumanization.     

Effectiveness of an attachment-based intervention for the assessment of parenting capacities in maltreating families: A randomized controlled trial

Even though Parenting Capacity Assessments (PCAs) are essential for child protection services to support placement decisions for maltreating families, presently no evidence-based PCA protocols are available. In this randomized controlled trial, we tested the quality of an attachment-based PCA protocol based on Video-feedback Intervention to promote Positive Parenting and Sensitive Discipline (VIPP-SD). We recruited 56 parent-child dyads (M_age children = 3.48 years) in Dutch family residential clinics that conduct PCAs to support placement decisions. After pretest, families were randomized to receive the Regular Assessment Procedure (RAP) (n = 28), or an additional assessment based on VIPP-SD (n = 28). An immediate post-test and a 10-month follow-up were conducted. Multilevel models showed that therapists felt equally confident about their recommendations regarding child placement for both groups and that they equally often modified their initial placement recommendations. Moreover, children in the VIPP-SD group did not show fewer behavior problems and did not experience recurring child maltreatment less often than children in the RAP group. Thus, we found no evidence that PCAs incorporating the VIPP-SD protocol outperformed PCAs as usual. We discuss possible explanations why in the current study VIPP-SD did not seem to add to the quality of the RAP.     

EyeRIS: A general-purpose system for eye-movement-contingent display control

In experimental studies of visual performance, the need often emerges to modify the stimulus according to the eye movements performed by the subject. The eye-movement-contingent display (EMCD) methodology enables accurate control of the position and motion of the stimulus on the retina. EMCD procedures have been used successfully in many areas of vision science, including studies of visual attention or eye movements and physiological characterization of neuronal response properties. Unfortunately, the difficulty of real-time programming and the unavailability of flexible and economical systems that can be easily adapted to the diversity of experimental needs and laboratory setups have prevented the widespread use of EMCD control. This article describes EyeRIS, a general-purpose system for performing EMCD experiments on a Windows computer. Based on a digital signal processor with analog and digital interfaces, this integrated hardware and software system is responsible for sampling and processing oculomotor signals and subject responses and for modifying the stimulus displayed on a CRT according to a gaze-contingent procedure specified by the experimenter. EyeRIS is designed to update the stimulus with a delay of only 10 msec. To thoroughly evaluate EyeRIS's performance, this study was designed to (1) examine the response of the system in a number of EMCD procedures and computational benchmarking tests; (2) compare the accuracy of implementation of one particular EMCD procedure, retinal stabilization, with that produced by a standard tool used for this task; and (3) examine EyeRIS's performance in one of the many EMCD procedures that cannot be executed by means of any other currently available device.     

The Selling Situation as a Moderator of the Personality-Sales Performance Relationship: an Empirical Investigation

Abstract

The lack of consistent success in using personality traits to predict the performance of salespeople is attributed to the cross-sectional nature of previous research. In this study, greater predictive accuracy and explanatory power is achieved when the selling situation is used as a moderating variable. The results are presented and the implications for sales force management and future research are considered.     

Leibniz-linked Pairs of Deductive Systems

A pair of deductive systems (S,S??) is Leibniz-linked when S?? is an extension of S and on every algebra there is a map sending each filter of S to a filter of S?? with the same Leibniz congruence. We study this generalization to arbitrary deductive systems of the notion of the strong version of a protoalgebraic deductive system, studied in earlier papers, and of some results recently found for particular non-protoalgebraic deductive systems. The necessary examples and counterexamples found in the literature are described.
