Navigating personal and relational concerns: the quest for equilibrium

The authors' personal-relational equilibrium model suggests that people come to seek equilibrium in their dedication to personal and relational concerns in that these 2 important needs cannot always be gratified simultaneously. The authors proposed that the experience of personal-relational disequilibrium motivates attempts to restore equilibrium and that achieving equilibrium promotes life satisfaction. Four studies revealed good support for the model. In Study 1, a manipulation of anticipated future disequilibrium (vs. equilibrium) as a result of overdedication to either the personal or relational domain caused reduced motivation to address concerns in that domain and increased motivation toward the complementary domain. In Study 2, narratives describing disequilibrium experiences (vs. equilibrium experiences) exhibited increased motivation to restore equilibrium and reduced life satisfaction. In Study 3, diary reports of everyday disequilibrium were associated with increased same-day motivation to restore equilibrium, reduced same-day life satisfaction, and increased next-day dedication of effort to the complementary domain. In Study 4, experiences of disequilibrium predicted reduced well-being 6 months later. Collectively, these findings extend knowledge of how people regulate themselves toward equilibrium in pursuing 2 fundamental human concerns.     

Consistent haptic feedback is required but it is not enough for natural reaching to virtual cylinders

In virtual reality it is easy to control the visual cues that tell us about an object's shape. However, it is much harder to provide realistic virtual haptic feedback when grasping virtual objects. In this study we examined the role of haptic feedback when grasping (virtual) cylinders with an elliptical circumference. In Experiment 1 we placed the same circular cylinder at the simulated location of virtual elliptical cylinders of varying shape, so that the haptic feedback did not change when the visually specified shape changed. We found that the scaling of maximum grip aperture with the diameter of the nearest principal axis (.14+/-.04) was much weaker than when grasping real cylinders (.54+/-.04, Cuijpers, Brenner, & Smeets, 2006 Grasping reveals visual misjudgements of shape. Experimental Brain Research, 175, 32-44). For the scaling of grip orientation with the orientation of the cylinder we found large individual differences: the range is .07-.82 (average .42+/-.07) as compared to .55-.79 (average .67+/-.03) for grasping real cylinders. In Experiment 2 we provided consistent haptic feedback by placing real cylinders that matched the location, shape and orientation of the virtual cylinders. The scaling gains of both maximum grip aperture (.39+/-.04) and grip orientation (.56+/-.08) were substantially higher than in Experiment 1, but still lower than for grasps to real cylinders. The variability between participants for the scaling of grip orientation was also much reduced. These results showed that although haptic feedback must be consistent with visual information, it is not sufficient for natural prehension. We discuss the implications of these findings in terms of the integration of visual information with haptic feedback.     

Speed-Dating

ABSTRACT— Scholars have recently begun to harness the immense power of speed-dating procedures to achieve important and novel insights into the dynamics of romantic attraction. Speed-dating procedures allow researchers to study romantic dynamics dyadically, with regard to potentially meaningful relationships, and with strong external validity. This article highlights the strengths and promise of speed-dating procedures, reviews some of their most exciting contributions to our understanding of the social psyche, and illustrates how scholars can employ speed-dating and its straightforward variants to study topics relevant to diverse subfields of psychological science.

Visuo-Proprioceptive Matching Errors Are Consistent with Biases in Distance Judgments

People make systematic errors when matching the location of an unseen index finger with that of a visual target. These errors are consistent over time, but idiosyncratic and surprisingly task-specific. The errors that are made when moving the unseen index finger to a visual target are not consistent with the errors when moving a visual target to the unseen index finger. To test whether such inconsistencies arise because a large part of the matching errors originate during movement execution, we compared errors in moving the unseen finger to a target with biases in deciding which of two visual targets was closer to the index finger before the movement. We found that the judgment as to which is the closest target was consistent with the matching errors. This means that inconsistencies in visuo-proprioceptive matching errors are not caused by systematic errors in movement execution, but are likely to be related to biases in sensory transformations.     

Recommendations for the Clinical Use of the Apperceptive Personality Test

The Apperceptive Personality Test (APT) is a new technique that combines the traditional story-telling method with a questionnaire about the characters in the story, to be filled out by the person being tested. The resulting information is tabulated, and a variety of scores are generated which yield information about the person's personality. The identified clinical signposts indicated by such scores are summarized in this article, along with two illustrative protocol fragments showing how the usual interpretive method is supplemented by the information from the questionnaire.
