The US-preexposure effect in lithium-induced flavor-aversion conditioning is a consequence of blocking by injection cues

In 2 experiments, rats received flavor-aversion conditioning in which the unconditioned stimulus (US) was an orally consumed solution of lithium chloride (LiCl). The resulting aversion was not attenuated by giving preexposure to injections of LiCl, although such preexposure did attenuate aversions established using injected LiCl as the US (Experiment 1). This outcome suggests that blocking by injection-related cues is responsible for the US-preexposure effect observed in this situation. Experiment 2 confirmed this interpretation by showing that presenting such cues (by giving an injection of saline) at the time that the LiCl was drunk resulted in an attenuation of conditioning in animals preexposed to injections of LiCl. The US-preexposure effect obtained in these experiments can be explained solely in terms of blocking by injection cues, although other mechanisms may contribute to the effect seen in other flavor-aversion paradigms.     

Analysis of the US-preexposure effect in flavor acceptance conditioning

In three experiments, rats received exposure to a sucrose solution followed by conditioning with a neutral flavor as the conditioned stimulus (CS) and sucrose as the unconditioned stimulus (US). In Experiments 1 and 2, some rats were given both the preexposure and the conditioning phases in a highly familiar context (the homecage), whereas other animals received both phases in a novel and distinctive context. In both cases the magnitude of the conditioning effect was reduced by preexposure to the US. Experiment 3 directly assessed the possible role of contextual cues by changing the context between the exposure phase and the conditioning phase but found no loss of the US-preexposure effect in these conditions. These results lend no support to the blocking-by-context account of the US-preexposure effect; alternative interpretations are considered.     

Violent self-harm in schizophrenia

Patients with schizophrenia have a substantial lifetime suicide risk, especially by violent means. Little published work exists on self-harm (SH) in this population. The goal of this study was to examine whether patients with schizophrenia were also more likely to self-harm in a violent manner. A retrospective analysis performed on method, motive, and suicidal intent in patients with schizophrenia (n = 50) and adjustment reaction (n = 138) who presented with SH over a 3-year period found that there was no significant difference between the two groups in terms of violence of method or suicidal intent. Presence of positive symptoms of schizophrenia was not significantly associated with use of a violent method. This study suggests that the expected pattern of violent SH in schizophrenia is inaccurate and for the majority the acts are of a similar nature to those seen in adjustment reactions.     

The “Second Injury” to Victims of Violent Acts

This paper, originally published in 1980, is a significant contribution to the study of psychological trauma and its treatment; particularly countertransference aspects of that treatment. Initially it was widely cited but then became little known, largely because of the inaccessibility of the original publication. The three major concepts in Symond's approach are: (1) self-hate and shame are the key dynamics in post traumatic distress; (2) ordinary professional attitudes of those who are supposed to help often intensify the traumatized person's self-hate and shame. Martin Symonds called this is the second injury; and (3) to counteract the self-hate and the shame, the professional must adopt a much more active attitude and behavior—in contrast to the previous experience the traumatized individual has had with the world of helpers (including family and friends). Here, Symonds addresses the analysts’ vulnerability and shame and their role as active instruments against self-hate and shame.

Goodbye,Daddy: An Autoethnographic Journey Through the Grief and Mourning Process

The purpose of this article is to present an autoethonographic study in how I experienced and communicated parts of the mourning process when my father died at the age of 73. The article highlights the stages of grief experienced during the first year. Autoethnographic means are used chronologically to explore how the loss of a family member impacts the stages of grief that are present and how they overlap. In particular, I highlight the events that carried meaning or provided an outlet to express one of the stages of grief. It is hoped that this article can be used to understand why grieving is not an overnight process, but rather is drawn out through the highs and lows of remembering a loved one.
