Sensitization and aversive conditioning: Effects on the startle reflex and electrodermal responding

Animal data suggest that shock sensitization as well as aversive learning potentiates the acoustic startle reflex. The present experiment tested, whether this shock sensitization also occurs in human subjects and whether it precedes aversive conditioning. Sixty subjects viewed—prior to conditioning—a series of slides of different emotional contents including the to be conditioned stimuli (CSs). Afterwards, the experimenter attached the shock electrodes and initiated shock exposure. Then, subjects were randomly assigned to view a series of two slides, each for eight acquisition trials in which one slide was followed by a shock. Subsequently, extinction trials (12 for each slide) were administered. During preconditioning, acquisition, and extinction, startle probes occurred unpredictably during and between slide viewing. Preconditioning data replicated previous results by Lang and his associates, showing that the startle response magnitude is directly related to the affective valence induced by the slides. Shock exposure strongly facilitated the startle reflex magnitude. This shock sensitization was absent for the skin conductance response. Course of learning also varied for both response systems. The data suggest that startle reflex potentiation indexes the acquisition of an avoidance disposition, which is preceded by a general sensitization of the protective reflexes. Skin conductance learning follows arousal changes and is modulated by cognitive processes.

Iraq and Afghanistan Veterans’ Experiences Living with their Parents after Separation from the Military

When military service members separate from the military, many return to their families of origin, living with their parents for a period of several weeks to years. While research with veterans and their spouses has documented the particular strain of this reintegration period on veterans and their partners, little research to date has examined veterans’ experiences living with their parents. The present study sought to fill this research gap by investigating veterans’ experiences living with their parents using qualitative, in-depth interviews with Iraq and Afghanistan veterans in California. Overall, veterans appreciated the instrumental and emotional support their parents provided when they separated. However, in some cases, living with parents also produced conflict and strain. In situations where adult veteran children had difficulty with the transition to civilian life or returned with mental health problems, parents were often the first to identify these problems and to support their children in accessing appropriate care. We analyze these findings in light of family systems theory, identifying ways in which adult veteran children continue a process of differentiation while living with their parents and maintaining emotional connectedness. We suggest ways that clinicians can better support veterans and their parents through the reintegration period and recommend that programming for military families explicitly include parents of service members in addition to conjugal families.     

BONE MARROW TRANSPLANTATION IN A PATIENT WHO EXPERIENCED TORTURE IN A PRISONER OF WAR CAMP: NARCISSISM AND SURVIVAL

Post-traumatic stress disorder has been described as a syndrome from which an individual may suffer as a result of extraordinary trauma. Torture of prisoners of war in Serbian camps during the war in Croatia is just such a stressful situation that requires mobilization of all defense mechanisms of an individual. The authors present a case study of a former prisoner of war who acquired acute myelogenous leukemia several months after release and was treated with bone marrow transplantation. On release the patient was medically examined, like all prisoners of war, and the findings did not suggest any disease. Because of the situation, the patient was in psychotherapeutic observation and treatment after his illness was diagnosed and throughout the transplantation treatment.     

Global problems,globalization, and predictability

The term globalization is questioned in its validity and applicability to structures other than verbal. Globalization is a historical term which changes its meaning with time and culture. It is not only that its content changes but the validity of a globalization concept changes with the historical perspective. Morever, solution of global problems depends heavily on the correct analysis of the problem. Without such an analysis there is no possibility to find even an approximate solution. Hence, predictability is impossible. There is no trend which is sufficiently long to make any reliable prediction for global problems other than the most simple ones.     

Suicide attempts: Patients with and without an affective disorder show impaired autobiographical memory specificity

A number of studies have shown reduced recall of specific autobiographical memories (AMs) in patients after attempted suicide, but in all of them the study samples were confounded with diagnoses of affective disorders. The present study aims to demonstrate impaired specific autobiographical memory in patients after a suicide attempt without a diagnosis of an affective disorder. Four groups were compared: (1) patients with an actual major depression and a suicide attempt; (2) patients after a suicide attempt without a lifetime history of an affective diagnosis; (3) patients currently suffering from major depression without a suicide attempt; and (4) control persons not suffering from either of the two conditions during their entire life. Individuals with major depression and a suicide attempt showed reduced specificity of AM and, most importantly, patients with a suicide attempt—despite the absence of an affective disorder—were equally impaired with recall of specific AMs as were patients with major depression. The authors propose that reduced specific AM is a common vulnerability factor that can lead either to the development of an affective disorder and/or to a suicide attempt.     

How equivalent are the action execution,imagery, and observation of intransitive movements? Revisiting the concept of somatotopy during action simulation

Jeannerod (2001) hypothesized that action execution, imagery, and observation are functionally equivalent. This led to the major prediction that these motor states are based on the same action-specific and even effector-specific motor representations. The present study examined whether hand and foot movements are represented in a somatotopic manner during action execution, imagery, and action observation.     

The Development of the Concept of Concrete Subjectivity from Kant to Neo-Kantianism

One long-running conundrum in Husserlian phenomenology revolves around the question of the identity of what Husserl calls the transcendental ego, a mysterious figure that he identifies as the subject of a genuinely transcendental phenomenology. In dialogue with both Husserl and his assistant and collaborator Eugen Fink (as well as recent commentary), I attempt in this article to give a solid account of the identity of this transcendental ego, and in particular to explain the connection between this figure and the empirical ego of the individual phenomenologist. I make particular reference to Fink's depiction of a "personal union" between these two egos in his Sixth Cartesian Meditation and to certain unclear hints in Husserl's 1923/1924 lectures on First Philosophy. Ultimately, I develop my own account of such a union, which explains the transcendental ego as a certain mode in which the phenomenologist might investigate his own experiences. On this basis, I argue, the status of phenomenology as a transcendental discipline can be understood without subjecting that discipline to certain criticisms that have been levelled against it.     

‘Sticking to a healthy diet is easier for me when I exercise regularly’: Cognitive transfer between physical exercise and healthy nutrition

Objective: Long-term rehabilitation success depends on regular exercise and healthy nutrition. The present study introduces a new framework to explain this association on a psychosocial level. The exercise–nutrition relationship was investigated by exploring the sequential mediation of habit strength and transfer cognitions.

Design: Analyses were performed at two measurement points in time (at 12 and 18?months after rehabilitation), involving 470 medical rehabilitation patients who participated in an exercise intervention.

Main outcome measures: Patients filled in paper-pencil questionnaires assessing exercise (t1) and habit strength, transfer cognitions and healthy nutrition at follow-up (t2).

Results: Habit strength and transfer cognitions mediated the relationship between exercise and nutrition.

Conclusion: Findings suggest that habit strength and transfer cognitions are important factors underlying the relationship between exercise and nutrition.     

On extremal axioms

In the paper translated here, Carnap and Bachmann shows that the apparently metalinguistic ‘extremal' axioms that are added to some axiom systems to the effect that the foregoing axioms are to apply as broadly, or as narrowly, as possible may be formulated directly as proper axioms. They analyze such axioms into four fundamental types, with the help of a concept of ‘complete’ isomorphism.
