The ground is dominant in infants’ perception of relative distance

When making relative distance judgments, adults attend to information provided by the ground surface and generally ignore information provided by ceiling surfaces. In the present study, we asked whether this ground dominance effect is present in infancy. Groups of 5- and 7-month-old infants viewed a display depicting textured ground and ceiling surfaces. Two toys, which were attached to vertical rods, were affixed to the display. The toys/rods were positioned so that one toy was specified as being nearer by the ground surface but farther away by the ceiling surface, while the other toy was specified as being farther away by the ground surface but nearer by the ceiling surface. Under monocular viewing conditions, the infants in both age groups reached preferentially for the toy that was specified as being nearer by the ground surface. This effect was significantly stronger than that observed under binocular viewing conditions. The findings indicate that the infants responded to the distance information provided by the ground surface to a greater extent than to information provided by the ceiling.     

Realism in confidence judgements of performance based on implicit learning

In two experiments we employed calibration methods to investigate the realism of participants' confidence ratings of their own classification performance based on knowledge acquired after training on an artificial grammar. In Experiment 1 participants showed good realism (but overconfidence) for grammatical strings but very poor realism for non-grammatical strings. Method of training (string repetition in writing or mere exposure) did not affect the realism. Furthermore, the participants underestimated their overall performance. In Experiment 2, using a more complex grammar and controlling for two types of associative chunk-strength, participants showed good realism (but still overconfidence) for both letter and symbol strings, irrespective of grammaticality. Together, these experiments show that implicit learning can give rise to knowledge products that are associated with fairly realistic meta-knowledge. It is argued that both the zero-correlation criterion and the guessing criterion are misplaced when used to define implicit knowledge; two reasons being that confidence judgements may be affected both by implicit knowledge and by inferences.     

Curiosity as a Guide to the Virtuous Life

We are concerned here with the existential question: In order to live a virtuous life, whether it is better to commit one's life to good works among humankind or to the perfection of one's spiritual being by turning away from humanity and devoting oneself entirely to God. We examine this issue—a controversy in moral philosophy from the time of the ancient Greeks—in a short story by Leo Tolstoy.     

A test of the four-factor model of impulsivity-related traits

In a recent article, Whiteside and Lynam [Person. Indiv. Diff. 30 (2001) 669] proposed a new model for understanding personality pathways to impulsive behavior. Their UPPS model maintains that there are four personality dimensions that are related differentially to impulsive behaviors: urgency, sensation seeking, (lack of) premeditation, and (lack of) perseverance. The purpose of the current study was to provide validation for this model and to test some of the specific hypotheses offered by Whiteside and Lynam. The sample used in this study consisted of 481 individuals who completed mailed surveys at age 20 and an in-depth laboratory protocol at age 21. Zero-order correlations and multiple regression analyses were used to examine the relations between the four personality traits and various forms of externalizing behaviors, several types of internalizing psychopathology, and intelligence. Results revealed that the four traits were differentially related to various behaviors and forms of psychopathology consistent with many of Whiteside and Lynam's predictions. Therefore, the UPPS model does appear to offer a novel and useful way of understanding behaviors and forms of psychopathology considered to be characterized by some form of impulsivity.     

A Biodata Inventory Administered via Interactive Voice Response (IVR) Technology: Predictive Validity, Utility, and Subgroup Differences

Although organizations are increasingly using interactive voice response (IVR) systems to help screen and select job applicants, few if any published studies have investigated the effectiveness of such systems. The current study responded to this need by evaluating a biodata inventory administered via IVR technology. A predictive validity study revealed that both a 42-item biodata measure and a more parsimonious 6-item composite correlated with supervisor ratings of performance and did not result in adverse impact or differential prediction. In addition, a utility analysis indicated that both IVR biodata measures would likely result in considerable financial gains to the hiring organization. The implications of these results for selection research and practice are discussed.     

Cork Older Adult Intervention Project: Outcomes of a gestalt therapy group with older adults

The study investigated the effects of a gestalt therapy group with older adults. A total of 43 adults, 65 years or older, were randomised into treatment and assessment control groups of 22 and 21 respectively. ANCOVA results indicated that group therapy participants reported less anger control and more overall expression of anger than the control participants. In addition, they were significantly more agreeable and less hostile and more clear-headed and less confused at the end of the group. These findings were supported by reported emotional changes. Younger group participants were significantly more composed and less anxious than younger control group members. Qualitative results further illustrated this reduction in anxiety. Participants significantly increased their level of clear-headedness and were less confused. Qualitative evidence also illustrated their clear-headedness and agreeableness. Exploratory analysis illustrated substantial learning about oneself by group participants.     

Stationäre oder teilstationäre Psychotherapie?

In a pilot study we compared two groups, one of inpatients and one of day clinic patients who were treated between January 1999 and December 2001 at the Department of Psychosomatics and Psychotherapeutic Medicine in Freiburg/Germany. Both settings offer a similar, multimodal and intensive psychotherapy program on a psychodynamic background. In a first explorative data analysis (sociodemographic data, SCL-90-R, IIP-C) we studied differences in severity of initial symptomatology and differences in outcome (prae/post). Patients with anorexia nervosa and a very low weight were preferentially treated in the inpatient setting. In addition the inpatient group of patients with a somatoform disorder showed higher degrees of somatization, as compared to patients with a somatoform disorder in the day clinic. Therapeutic change with respect to psychopathology however did not differ between the two settings: both groups showed a significant improvement during the course of therapy.     

A turnover model for the Mexican maquiladoras

Existing turnover models have been developed and tested almost exclusively in Anglo cultures. Thus, there is reason to question whether these models apply to workers elsewhere. We addressed this question using as participants 47 Mexican maquiladora workers. Through interview responses analyzed using a variation of grounded theory-building, we inductively created a model of voluntary turnover with research propositions. We then compared the new model to traditional turnover models, concluding that many of their constructs and mechanisms are familiar in the maquiladoras. However, the cultural and economic environment perceived by the workers help determine the precise antecedents, their salience, and the strength of their linkages with turnover. Finally, we suggest how turnover research might be extended to better apply to workers in other cultures.
