RWMODEL II: computer simulation of the Rescorla-Wagner model of Pavlovian conditioning

RWMODEL II simulates the Rescorla-Wagner model of Pavlovian conditioning. It is written in Delphi and runs under Windows 3.1 and Windows 95. The program was designed for novice and expert users and can be employed in teaching, as well as in research. It is user friendly and requires a minimal level of computer literacy but is sufficiently flexible to permit a wide range of simulations. It allows the display of empirical data, against which predictions from the model can be validated.     

The Martin Buber-Carl Jung disputations: protecting the sacred in the battle for the boundaries of analytical psychology

The Martin Buber-C.G.Jung disputations rather than the Freud-Jung split or Samuels's post-Jungian categories is considered the more significant paradigm for understanding the conflicts erupting within the Jungian community surrounding clinical practice and candidate training. Looking through the lens of the Freud-Jung split keeps the conflicts focused on the theoretical and technical differences concerning such concepts as object-relations, transference-countertransference, neutrality, clinical boundaries. The Buber-Jung disputations move the discussion into a different and more foundational arena, namely the vertical and horizontal psychological considerations of the experience of the Sacred and how that dimension is supported or thwarted in clinical practice and candidate training by the respective allegiances of the 'warriors' in the 'Holy Wars'. Experiencing the texture of the Buber-Jung disputations as well as grappling with their content suggests that a more dialogical approach to actual clinical material may be a more fruitful way to understand the work of analysis and the business of candidate training.     

Organizational Structure,Context, and Climate: Their Relationships to Job Satisfaction at Three Managerial Levels

Managers from 120 organizations (183 men and 27 women) from four major Canadian urban centers were surveyed about their job satisfaction. Seven aspects of job satisfaction were evaluated: satisfaction with the firm, pay, promotional opportunities, the job itself, other managers at the same level, immediate supervisor, and subordinates. Overall, managers at the highest level reported the most job satisfaction. For presidents, satisfaction was related to the organization's structure and context, as well as to its climate, whereas for middle managers and vice presidents, job satisfaction was related more frequently to the organization's climate and less frequently to its structure and context.     

Anger-congruent behaviour transfers across driving situations

Anger and aggression on the road may sometimes appear unprovoked and unrelated to current driving circumstances. It is unclear whether such anger and aggression arises because of events prior to those circumstances in which anger is experienced and aggression is exhibited. In this study, time pressure and enforced following of a slowly moving vehicle were used to increase drivers’ anger in order to assess whether affect and behaviour during a subsequent, non-provocative, drive would change accordingly. Ninety-six drivers drove twice in a simulated urban environment. During the first drive, oncoming traffic and a slowly moving lead vehicle required that half of the drivers travelled far slower than they would choose. During the second drive, drivers again followed slower vehicles and were required to respond to traffic events not encountered in the manipulation drive. Mood (Profile of Mood States) was assessed before and after each drive, and anger evaluations, arousal (heart rate) and behaviour (speed, lane position and collisions) were measured during drives. Anger increased and both mood and driving behaviour deteriorated in drivers exposed to slower lead vehicles, compared with control group drivers. These behavioural differences of speed and lane positioning carried over into the subsequent drive even to driving situations unlike those where provocation had previously occurred. Drivers who had previously been impeded later approached hazards with less caution, and attempted more dangerous overtaking manoeuvres. It is concluded that sometimes dangerous driving may result from anger provoked by circumstances other than those in which the behaviour is exhibited.     

Role of the primary somatosensory cortex in motor learning: An rTMS study

Somatosensation is thought to play an important role in skilled motor learning. The present study investigated how healthy adults learn a continuous implicit motor task when somatosensation is altered by 1 Hz repetitive transcranial magnetic stimulation (rTMS) delivered over the primary somatosensory cortex (S1). Twenty-seven right-handed participants enrolled in a two-part experiment. In Experiment 1, we verified that 20 min of 1 Hz rTMS over S1 disrupted cutaneous somatosensation (indexed by two-point discrimination) in the wrist/hand; the impact of 1 Hz rTMS on wrist proprioception (tested by limb-position matching) was variable. Sham rTMS had no effect on either measure. We exploited these effects in Experiment 2 by pairing either 1 Hz or sham rTMS with practice of a continuous tracking task over two separate sessions on different days. Implicit motor learning was indexed on a third, separate retention test day when no rTMS was delivered. Across practice in Experiment 2, both the 1 Hz and sham rTMS groups showed improved tracking performance; however, 1 Hz rTMS was associated with less accurate tracking and smaller improvements in performance. Importantly, at the no rTMS retention test the effects of altering sensation with stimulation over S1 were still evident in the persistently less accurate tracking behavior of the 1 Hz rTMS group. The current study shows that disruption of somatosensation during task practice impairs the magnitude of change associated with motor learning, perhaps through the development of an inaccurate internal model.

Association of Rorschach and MMPI psychosis indicators and schizophrenia spectrum diagnoses in a Russian clinical sample

In this study, I investigated the relationships among psychological test variables and schizophrenia spectrum diagnoses in a Russian sample of 180 psychiatric patients. Schizophrenia is understood somewhat differently in Russia than in the West. Analyses compared Rorschach (SCZI, PTI; Exner, 2001) and MMPI (Berezin, Mitroshinkov, & Sokolova, 1994) psychosis indicators (Sc, Sc3, Sc6, and BIZ) and 3 diagnostic systems: (a) Russian traditional, (b) the Russian-modified International Classification of Diseases (9th ed. [ICD-9]; Ministerstvo Zdravokhraneniya SSSR, 1982), and (c) the nonmodified ICD-10 (World Health Organization, 1992; comparable to the Diagnostic and Statistical Manual of Mental Disorders [4th ed.], American Psychiatric Association, 1994). Results showed modest support for the SCZI and PTI but not the MMPI indicators. While the field awaits further evidence, psychologists should proceed with caution when using the Rorschach and MMPI to assess for psychosis among Russians.
