Dante’s Divine Comedy and modern depth therapy

The author discusses a connection between the modern analysand’s experience of depth therapy and the Christian pilgrim’s experience of confession, penitence and transformation as described by Dante in his Divine Comedy. She looks at structure and order in the context of psychotherapy. Taking Adriana Mazzarella’s ‘In Search of Beatrice’ as a guide, she examines a Jungian interpretation of the poem as an analogy of therapeutic initiation. She explores the idea of cultural complexes via the study of the medieval world view as one distinct from our own. She demonstrates the way in which study of the Comedy unexpectedly helped her survive an experience of long-term psychotherapeutic work.     

Travel behavior changes and responses to advanced traveler information in prolonged and large-scale network disruptions: A case study of west LRT line construction in the city of Calgary

The objective of this study was the investigation of travel behavioral effects of the reduction in traffic capacity resulting from the construction of the West LRT (Light Rail Transit) line in the city of Calgary, Alberta, Canada. Travelers’ responses to real-time information providing traffic updates and advisory detours due to lane/road closures were also examined. The West LRT alignment extends approximately 8.2 km from downtown into the city’s southwest. Many road closures took place in the vicinity of the LRT line construction zones, inducing significant delays to traffic. Data on travelers’ behavioral responses and responses to real-time information were obtained by conducting a survey on a sample of users of the main road affected by the construction. The survey also investigated the effects of West LRT line construction on drivers’ daily commutes, including increases in travel times, mode choices, alternate route choices, and selection of sources of information on traffic conditions. A significant change in the selection of transportation mode was caused by West LRT construction. Throughout the construction period, there was a decrease in the percentage of respondents who reported private vehicles as their first choice and an increase in the percentage of respondents who preferred public transit as their first and second choices. Radio was found to be the most preferred source for traffic updates and detour advice, followed by variable message signs (VMS). The findings of the en-route information model showed that driving experience, employment status, travel time and purpose, and desire for pre-trip information had significant effects on traveler’s rerouting decisions after getting en-route information through VMS. The results from this study are of interest for understanding behavioral changes for the purposes of traffic management, mitigation schemes and design of advanced traveler information systems in response to network disruptions.     

Birth Order Position and Prosocial Tendencies

This study investigated the relationship between psychological birth order position and different types and levels of prosocial tendencies. An ex postfacto, between-family research design was used. Data on prosocial tendencies were obtained from 888 college students (females = 80.4%, mean age = 20.94 yrs, SD = 2.83; males = 19.6%, mean age = 21.62 yrs, SD = 2.44). Participants completed a biographical questionnaire as well as the Prosocial Tendencies Measure (Carlo & Randall, 2002). Data were analysed to compare and contrast prosocial tendencies between demographics using parametric ANOVAs, t tests and the Mann-Whitney Test. Significant differences in prosocial tendency scores were only found between middle-borns and last-borns on altruism, with middle-borns scoring significantly higher in prosocial tendencies than last-borns. There is no evidence to suggest that a definitive link between prosocial tendencies and birth order exists in this study.     

Solving distant analogies reduces belief-based responding in transitive inference

ABSTRACT

Previous research demonstrated that relational processing in transitive inference problems can be disrupted by belief-based content. Given the premises, The horse is larger than the goat, and The goat is larger than the elephant, accepting the valid conclusion, The horse is larger than the elephant suggests use of relational processing whereas accepting the invalid conclusion The elephant is larger than the horse indicates belief-based responding. This research examined whether solving analogies influenced participants’ reliance on belief-based or relational processing. Participants generated solutions to either distant analogies (e.g. nose:scent::antenna: ______) or near analogies (e.g. nose:scent::tongue:______) before evaluating the conclusions of transitive inference problems that were valid (V) or invalid (I) and believable (B), unbelievable (U) or neutral (N). Solving distant analogies eliminated belief-based responding (possibly reflecting improved inhibitory control) and facilitated relational responding on VU problems.     

Environmental enrichment results in cortical and subcortical changes in levels of synaptophysin and PSD-95 proteins

Experience-dependent plasticity is thought to involve selective change in pre-existing brain circuits, involving synaptic plasticity. One model for looking at experience-dependent plasticity is environmental enrichment (EE), where animals are exposed to a complex novel environment. Previous studies using electron microscopy showed that EE resulted in synaptic plasticity in the visual cortex and hippocampus. However, the areas in the brain that have been examined following EE have been limited. The present study quantified potential synaptic plasticity throughout the brains of C57BL/6 mice using an enzyme-linked immunosorbent assay (ELISA) for two synaptic proteins, synaptophysin and PSD-95. EE resulted in increased synaptophysin and PSD-95 levels through major brain regions, including anterior and posterior areas of the forebrain, hippocampus, thalamus, and hypothalamus. However, no changes in synaptophysin were detected in the cerebellum. These results demonstrate that EE results in an increase in levels of both pre- and post-synaptic proteins in multiple regions of the brain, and it is possible that such changes represent the underlying synaptic plasticity occurring in EE.     

Timing at the Start of Associative Learning

Some theories of associative learning imply that time plays a fundamental role in the acquisition process. Consistent with these theories, this paper presents evidence that the time from the onset of a conditioned stimulus (CS) until presentation of the unconditioned stimulus (US) is learned very rapidly at the start of training. We report two autoshaping studies and a study on aversive conditioning in goldfish in which we examine timing at the start of conditioning. We also review data from a number of other conditioning preparations, including fear-potentiated startle, appetitive conditioning in rats, and eyeblink conditioning in rabbits, that report conditioned response (CR) timing early in training. Acquisition speed and the very first expressions of conditioned responding often show sensitivity to the time of US presentation. In instances where temporal control is slowly expressed, it is likely due to performance factors, not to slow learning about time. In fact, the learning about time may be a necessary condition for associative learning.     

No Time of Day Modulation or Time Stamp on Multiple Memory Tasks in Rats

Various demonstrations of “time stamp” effects in the animal learning literature have reinforced the idea that circadian information is encoded as part of a combined internal/external representation of context and that this contextual information is utilized for complex retrieval processes supporting memory. The goal of the present series of experiments is to assess this idea by manipulating training/testing circadian times on a battery of learning and memory tasks commonly used in the rodent. The data obtained from five experiments using four different learning and memory paradigms provide no evidence for “time stamp” effects on place memory, context memory (aversive or appetitive), or S-R habit learning.

Coaching

Zusammenfassung Coaching ist in Wirtschaftsunternehmen weit verbreitet. Angesichts der stetig steigenden Ver?nderungsgeschwindigkeit der Arbeits- und pers?nlichen Lebenswelten suchten zun?chst Führungskr?fte professionelle Coaches, die ihnen als vertraute Gespr?chspartner zur Seite standen. Coachingma?nahmen werden aber auch zunehmend von Politikern, Medienvertretern, Künstlern und Freiberuflern nachgefragt. Die derzeitigen Coachingkonzepte enthalten zumeist eine Kombination von allgemein-psychologischen, kognitiv-verhaltensorientierten, psychodynamischen und systemischen Techniken, modifiziert durch die Lebenserfahrung und Weltanschauung der Coaches. Es existiert eine Vielzahl eklektischer Praktiken, die theoretisch nicht koh?rent begründet und wissenschaftlich nicht verl?sslich evaluiert sind. Da Coaching in der Praxis h?ufig eine Form von Psychohygiene und Psychotherapie für Gesunde darstellt, ist es nahe liegend die Ergebnisse psychotherapeutischer Theoriebildung, Praxiserfahrung und Forschung als Grundlage des Coaching zu nutzen. Drei wissenschaftlich fundierte Aspekte des Coaching lassen sich herausstellen: Die hilfreiche Beziehung, kognitiv-verhaltensorientiertes Training und psychodynamisches Verstehen. Darüber hinaus ist es viel versprechend die Methoden der Psychotherapieforschung zur Untersuchung von Ergebnis und Prozess von Coachingma?nahmen anzuwenden.
