Training Soviet immigrant therapists in the field of group psychotherapy

Between 1970 and 1990 about one-half million Jews immigrated to Israel, most of them from the former Soviet Union, including many mental health therapists who had trained and worked in the Soviet Union. This article addresses the special characteristics of this population, in general, and of the mental health therapists, in particular. It relates these characteristics to training for group psychotherapy. Key issues include their unique experience of the inner world as a source of danger, the specific defensive modes connected with this experience, their perception of authority as an agent of ideology, and their representation of the group as a persecutory entity and as a vehicle of indoctrination.     

Religiosity and obsessive-compulsive behavior in Israeli Jews

Individual differences in obsessive-compulsive (OC) behavior in various cultures correlate with religiosity. The current paper explored the so far unstudied relationship between religiosity and OC behavior in Israeli Jews. Two studies were conducted. Study 1 focused on the relationship between religiosity and OC behavior in a representative sample of Israeli students. Study 2 focused on religious change and OC behavior in a non-random sample of 31 individuals who had become more religious (the MR group), and 30 individuals who were less religious (the LR group) than their parents. Instruments used were the Maudsley obsessive-compulsive inventory (MOCI), the student religiosity questionnaire, and questions about parental home observance, upbringing, and changes in religiosity. In the first study, no association was found between religiosity and OC behavior. Religiosity was related to some degree to perfectionism and to the parental attitude to upbringing. In the second study, a significant difference was observed between the MR and the LR groups on OC behavior as measured by the MOCI. Conclusion, among Israeli Jews a lot of religious observance is non-reflective, and is not associated with individual differences in personality or OC symptoms. Those who undergo religious change may do so in response to their behavioral propensities. One such path is that the more OC become MR, and the less OC less religiously observant.     

EMG activity in selected target muscles during imagery rising on tiptoes in healthy adults and poststroke hemiparetic patients

The authors sought to gain further knowledge about activation of target muscles during imagery engagement in a motor task. Six hemiparetic patients and 9 healthy participants performed 3 real rises on tiptoes and then, after pausing, 3 imagery rises on tiptoes. Metronome beats guided the rate of rises and descents. Electromyographic (EMG) activity from the medial gastrocnemius and the rectus femoris muscles were monitored bilaterally throughout the performance of both tasks. In 3 healthy participants and 3 individuals with hemiparesis, EMG activity was related to the imagery task in at least 1 of the target muscles. Conversely, in the other participants, motor imagery practice was not accompanied by task-related EMG activity in the monitored muscles. In all cases, the increment in activation level during motor imagery practice was very low in comparison with that of real performance. The findings were not unequivocal; therefore, EMG activity may sometimes, but not always, be recorded during motor imagery practice both in healthy individuals and in poststroke hemiparetic participants. Further research is needed to align motor imagery practice with the objectives of motor rehabilitation.     

The Effect of Accuracy of Performance Evaluation on Learning From Experience: The Moderating Role of After-Event Reviews

Two studies (one field, one experimental) found that the more accurately individuals evaluated their performance, the better they performed on a subsequent task. The first study also found that the more individuals overestimated their previous performance, the lower was their performance on the next task. In contrast, the evaluation accuracy of the underestimators was unrelated to their subsequent performance. The second study found that when participants received feedback from an external authority, the effect of the inaccuracy of self-performance evaluation on subsequent performance was reduced. The results of the 2 studies are explained in motivational and cognitive terms.     

Faking Fast and Slow: Within-Person Response Time Latencies for Measuring Faking in Personnel Testing

Purpose

Item response time (RT) latencies offer a potentially promising approach for measuring faking in personnel testing, but have been studied almost exclusively as either long or short RTs relative to group norms. As such, the ability to reliably assess faking RTs at the individual level remains a challenge. To address this issue, the present study set out to examine the usefulness of a within-person difference score index (DSI) method for measuring faking, in which “control question” (baseline) RTs were compared to “target question” RTs, within single test administrations.

Design/Methodology/Approach

Two hundred six participants were randomly selected to simulated faking or honest testing conditions, and were administered two types of integrity test items (overt and personality), whereby group classification (faking/honest) served as the main dependent variable.

Findings

Faking condition RTs were longer than honest condition RTs for both item types (overt: d = .43; personality: d = .47), and overt item RTs were slightly shorter than personality item RTs in both testing conditions (honest: d = .34; faking: d = .41). Finally, using a sample cut score, the DSI correctly classified an average of 26 % more cases of faking, and 53 % less false positives, compared to the traditional normative method.

Implications

The results suggest that the DSI can be an advantageous method for identifying faking in personnel testing scenarios.

Originality/Value

This is the one of the first studies to propose a practical method for identifying individual-level faking RTs within single test administrations.

     

The reverse hierarchy theory of visual perceptual learning

Perceptual learning can be defined as practice-induced improvement in the ability to perform specific perceptual tasks. We previously proposed the Reverse Hierarchy Theory as a unifying concept that links behavioral findings of visual learning with physiological and anatomical data. Essentially, it asserts that learning is a top-down guided process, which begins at high-level areas of the visual system, and when these do not suffice, progresses backwards to the input levels, which have a better signal-to-noise ratio. This simple concept has proved powerful in explaining a broad range of findings, including seemingly contradicting data. We now extend this concept to describe the dynamics of skill acquisition and interpret recent behavioral and electrophysiological findings.     

Comparing expert and novice understanding of a complex system from the perspective of structures, behaviors, and functions

Complex systems are pervasive in the world around us. Making sense of a complex system should require that a person construct a network of concepts and principles about some domain that represents key (often dynamic) phenomena and their interrelationships. This raises the question of how expert understanding of complex systems differs from novice understanding. In this study we examined individuals’ representations of an aquatic system from the perspective of structural (elements of a system), behavioral (mechanisms), and functional aspects of a system. Structure-Behavior-Function (SBF) theory was used as a framework for analysis. The study included participants from middle school children to preservice teachers to aquarium experts. Individual interviews were conducted to elicit participants’ mental models of aquaria. Their verbal responses and pictorial representations were analyzed using an SBF-based coding scheme. The results indicated that representations ranged from focusing on structures with minimal understanding of behaviors and functions to representations that included behaviors and functions. Novices’ representations focused on perceptually available, static components of the system, whereas experts integrated structural, functional, and behavioral elements. This study suggests that the SBF framework can be one useful formalism for understanding complex systems.     

Numbers and space: Associations and dissociations

A cornerstone of contemporary research in numerical cognition is the surprising link found between numbers and space. In particular, people react faster and more accurately to small numbers with a left-hand key and to large numbers with a right-hand key. Because this contingency is found in a variety of tasks, it has been taken to support the automatic activation of magnitude as well as the notion of a mental number line arranged from left to right. The present study challenges the presence of a link between left-right location, on the one hand, and small-large number, on the other hand. We show that a link exists between space and relative magnitude, a relationship that might or might not be unique to numbers.     

Perceptual Learning

The extent of adult improvement in not only complex but also simple perceptual tasks is remarkable. Although this phenomenon has been noted and studied since the middle of the 19th century, recent advances in the study of brain physiology and anatomy afford new insights. Improvement specificity suggests that changes involve early sensory cortical areas, previously thought to lose their plasticity following the first years. The critical role of selective attention, even in learning the simplest tasks, as well as the precedence of learning easy cases, suggests the involvement of high-level cortical areas. Learning easy cases is more general than learning difficult cases. This pattern suggests the involvement of both high- and low-level areas in an orderly manner, with easy learning beginning at high-level areas and harder cases being resolved by access to low-level areas. The mapping of behavioral findings to underlying brain sites provides a unified framework for this interdisciplinary field.
