A Comparison of Assessment Center Practices in Organizations in German‐speaking Regions and the United States

The development, execution, and evaluation of ACs in 281 German, Swiss, and Austrian organizations are examined for compliance with professional guidelines and consideration of moderator variables of validity, and the results are compared with those reported for U.S. companies ( Spychalski et al., 1997 ). The authors show that some recommendations (e.g., systematic testing of reliability and validity) have not received sufficient attention in either the German‐speaking or U.S. sample and that compliance with guidelines (e.g., the application of information policy to assessees) varies across the countries studied. The most important cross‐national differences in the development, execution, and evaluation of ACs are explained as results of ideologically rooted reservations, insufficient professionalization in some aspects of intraorganizational AC use, as well as specific aspects of the Labor‐Management Act and similar legislation in German‐speaking regions. These factors are linked with a cultural difference—institutionalized collectivism, which is greater in German‐speaking regions than in the United Sates.     

The effects of a target–stimulus reminder on performance in a novel object recognition task

The effects of original training-stimulus pre-test reminders were examined in a novel object recognition (NOR) task. NOR is a task that examines memory for complex stimuli, and is driven by the rats’ tendency to spend significantly more time exploring novel objects over those previously experienced. In this task, a delay is imposed between a training experience during which the animal is allowed to investigate a set of identical objects, and a later test exposure where the animal encounters one of the original objects and a novel object with which it has had no previous experience. Experiment 1 demonstrated that performance at 24 h is significantly worse than at an immediate delay (1 min). In the second experiment, it was demonstrated that neither a 10-s nor a 30-s reminder treatment, in the absence of training, resulted in a level of preference for novelty, a measure of memory for the original object, that was significantly greater than chance. Experiment 3 illustrated significant performance effects of a 30-s training stimulus reminder administered 15 min prior to test with a 24-h retention interval. The final experiment illustrated that the additional 30-s of object exposure is effective in enhancing performance only if it occurs shortly prior to test. Animals receiving the additional 30-s immediately following training did not experience such beneficial effects. It was concluded, based upon these results, that pre-test training-stimulus reminders in this task produce effects similar to those seen in more traditional tasks of learning and memory.     

Gender-based rejection sensitivity and academic self-silencing in women

Building on prior work on rejection sensitivity, we propose a social-cognitive model of gender-based rejection sensitivity (Gender RS) to account for individual differences in how women perceive and cope with gender-based evaluative threats in competitive, historically male institutions. Study 1 develops a measure of Gender RS, defined as anxious expectations of gender-based rejection. Studies 2-5 support the central predictions of the model: Gender RS is associated with increased perceptions of gender-based threats and increased coping by self-silencing--responses that reinforce feelings of alienation and diminished motivation. Study 2 shows that Gender RS is distinct from overall sensitivity to rejection or perceiving the world through the lens of gender. Study 3 shows that Gender RS becomes activated specifically when gender-based rejection is a plausible explanation for negative outcomes. Study 4 provides experimental evidence that Gender RS predicts lower academic self-confidence, greater expectations of bias, and avoidance of opportunities for further help from a weakness-focused expert evaluator. Study 5 tests the Gender RS model in situ, using daily diaries to track women's experiences during the first weeks in a highly competitive law school. Implications for women's coping with the subtle nature of contemporary sexism are discussed as well as the importance of institution-level checks to prevent the costs of gender-based rejection.     

Use of slope and feature cues in pigeon (Columba livia) goal-searching behavior

Terrain slope provides a directional frame of reference for reorientation and navigation, similar to cardinal directions. Previous studies have shown that, in a goal location task, slope is a very salient cue and that pigeons tend to rely on it even if it is not the most informative cue. Such a strong dependence on one type of information, when there are more effective predictors of reward, is a key premise for a modular view of information processing. Here we tested the provocative hypothesis of a "slope module" for reorientation in slanted environments. Pigeons had to solve a goal location task using slope or another, theoretically salient cue: a beacon feature. Overall, searching behavior was controlled almost equally by the two cues. The fact that, for the first time, slope failed to capture most of the associative strength allows us to reject a strong modularity view and suggests instead that there is competition between cues based on salience. As an interesting additional finding, the reliance on slope and the feature was affected by training location (uphill vs. downhill), suggesting the possibility of a modulatory role of effort on the cue-weighting mechanism of reorientation.     

MRI-Assessed Volume of Cerebellum Correlates with Associative Learning

Richard F. Thompson's cerebellar model of classical eyeblink conditioning highlights Purkinje cells in cerebellar cortex and principal cells in the deep cerebellar nucleus as the integrating cells for acquisition of conditioned responses (CRs). CR acquisition is significantly slower in rabbits with lesions to cerebellar cortex and in Purkinje cell-deficient mice that lose all cerebellar cortical Purkinje cells. Purkinje cells are the largest neurons in the cerebellum and contribute significantly to cerebellar volume. Magnetic resonance imaging (MRI) was used to assess cerebellar volume in humans. Cerebellar volume was related to eyeblink conditioning (400-ms delay procedure) in 8 adults (21-35 years) and compared to 8 older adults (77-95 years) tested previously (Woodruff-Pak, Goldenberg, Downey-Lamb, Boyko, & Lemieux, 2000). In the young adult sample, there was a high correlation between percentage of CRs in a session and cerebellar volume (corrected for total intracranial volume [TIV], r =.58, p =.066). There were statistically significant age differences in cerebellar volume, t(14) = 8.96, p <.001, and percentage of CRs, t(14) = 3.85, p <.002, but no age difference in TIV. Combining the young and older adult sample, the correlation between percentage of CRs and cerebellar volume (corrected for TIV) was.832 (p <.001). Cerebellar volume showed age-related deficits likely due to Purkinje cell loss. Individual differences in classical eyeblink conditioning are associated with differences in cerebellar volume, supporting Thompson's model of a cerebellar cortical role in facilitating this form of associative learning.     

Signal detection theory, the approach of choice: model-based and distribution-free measures and evaluation

New and old methods of analyzing two-choice experiments with confidence ratings are evaluated. These include the theory of signal detectability (TSD), Luce's choice theory,nonparametric techniques based on areas under receiver-operating characteristic (ROC) functions, andmethods based on S' and omega, proposed by Balakrishnan and his colleagues. New methods for assessing the bias of a complete ROC function are proposed, together with an additional area-based measure of response bias. Area measures of both sensitivity and bias proved the most consistent. Response bias for a full ROC function was larger than bias at the cut point and also provided additional information. Participants showed voluntary control of bias for all measures except omega. Unequal variance versions of TSD and choice models gave similar fits to data, with the choice model closer to an equal variance version. Discrimination data from Balakrishnan (1999) formed the empirical test bed.     

‘Only connect’ – a sexually abused girl's rediscovery of memory and meaning as she works towards the transition from a therapeutic community to a foster-family

This paper looks at the role of individual psychotherapy with a severely sexually abused girl in a therapeutic community, and the place of this work as she makes the transition into foster-care. It emphasizes the importance, not only of the individual work, but also of the drawing together of the work around the child, particularly at such a critical time. There is discussion of the ideas of ‘deadness’ versus ‘aliveness’ in the therapy, and detailed case material is used.     

Validity of the Inventory of Interpersonal Problems (IIP–64) for Predicting Assertiveness in Role-Play Situations

The Buddhist notion of “nonattachment” (release from mental fixations) is related to but distinguishable from the Western construct of attachment. Secure (or insecure) attachment is based on internal working models related to security (or insecurity), whereas nonattachment is based on insight into the constructed and impermanent nature of mental representations. Based on historical and contemporary Buddhist scholarship, we designed the Nonattachment Scale and evaluated its psychometric properties in various samples. We also present evidence consistent with Buddhist theory that nonattachment is psychologically and socially adaptive, and we offer directions for further research on nonattachment.
