Loss Shapes Political Views? Terror Management,Political Ideology,and the Death of Close Others

This study used longitudinal data from a nationally representative sample to examine long-term effects of loss on political views. Drawing on terror management theory, it was predicted that individuals would reinforce their political views in response to the loss of relatives or close friends. Results were consistent with this hypothesis, though the effects were more pronounced among conservatives than liberals. By showing that the death of loved ones can shape political attitudes, the findings shed new light on the long-term effects of death confrontation.     

Conflict and support interactions in marriage: An analysis of couples’ interactive behavior and on‐line cognition

The present study examined the similarities and differences in couples’ interactive behavior and interaction‐based cognition that emerged in comparisons of conflict and support interactions in marriage. In a laboratory experiment, 53 couples were randomly assigned to the conditions of a 2 (type of interaction: conflict vs. support) × 2 (initiator of interaction: man vs. woman) factorial design. Partners provided questionnaire data and participated in a joint interaction and video review task. The data revealed substantial behavioral similarities (i.e., some classes of validation/facilitation behaviors and neutral problem‐solving behaviors) as well as behavioral differences (i.e., some classes of invalidation/oppositional behaviors) between conflict and support interactions, controlling for levels of marital satisfaction. Partners’ interaction‐based cognition (e.g., feeling understood, satisfied) was especially affected by classes of validation/facilitation behaviors and was consistently related to marital satisfaction. In broad terms, the impact of a particular behavior on partners’ ongoing cognition did not depend on the interaction domain (conflict vs. support) in which the behavior occurred.     

Resistance to extinction in evaluative conditioning

A well-demonstrated phenomenon in traditional Pavlovian conditioning research with humans is that of experimental extinction. In contrast, human evaluative conditioning research suggests that evaluative learning shows marked resistance to extinction. Here, the authors replicate both findings concurrently. Two differential fear conditioning experiments with an electrocutaneous stimulus as the unconditioned stimulus evidenced (a) sensitivity to extinction using an autonomic skin-conductance measure and (b) complete resistance to extinction using an affective-priming measure. The results corroborate the idea that evaluative conditioning is more resistant to extinction than is expectancy learning (F. Baeyens, P. Eelen, & G. Crombez, 1995).     

Relations among comfort of fabrics, ratings of comfort, and visual vigilance

Little is known about the relationship between perceptions of comfort and cognitive performance. In the present study, 40 subjects (20 men and 20 women) participated in a computerized cognitive task of visual vigilance. The computer task was completed under three conditions of clothing and tactile comfort: one condition was that of extreme discomfort, effected by the wearing of wool clothing material on the arms and neck in addition to each subject's normal clothing, including a short sleeve shirt; a second condition was that of minimal discomfort, effected by the wearing of cotton clothing material on the arms and neck, in addition to each subject's normal clothing, including a short sleeve shirt; and a third condition was a control, wherein no experimental material was added to each subject's normal clothing, including a short sleeve shirt. Comfort was assessed prior to, during, and after testing. Reaction time and accuracy of 400 trials of a visual vigilance task were assessed under each of these three conditions. Analysis indicated a significant difference in perceived comfort between the wool and each of the other conditions. In addition, both reaction time and accuracy declined in the wool condition. This study is among the first to identify a direct significant relationship between perceptions of clothing comfort and cognitive performance.     

A simple and sensitive method to measure timing accuracy

Timing accuracy in presenting experimental stimuli (visual information on a PC or on a TV) and responding (keyboard presses and mouse signals) is of importance in several experimental paradigms. In this article, a simple system for measuring timing accuracy is described. The system uses two PCs (at least Pentium II, 200 MHz), a photocell, and an amplifier. No additional boards and timing hardware are needed. The first PC, a SlavePC, monitors the keyboard presses or mouse signals from the PC under test and uses a photocell that is placed in front of the screen to detect the appearance of visual stimuli on the display. The software consists of a small program running on the SlavePC. The SlavePC is connected through a serial line with a second PC. This MasterPC controls the SlavePC through an ActiveX control, which is used in a Visual Basic program. The accuracy of our system was investigated by using a similar setup of a SlavePC and a MasterPC to generate pulses and by using a pulse generator card. These tests revealed that our system has a 0.01-msec accuracy. As an illustration, the reaction time accuracy of INQUISIT for a few applications was tested using our system. It was found that in those applications that we investigated, INQUISIT measures reaction times from keyboard presses with millisecond accuracy.
