Selection for conditionability in Drosophila melanogaster.

Successful bidirectional selective breeding of Drosophila melanogaster for excitatory conditionability is reported, using the reliable measures of individual differences (first described by Holliday & Hirsch, 1984, 1986a, 1986b) to test 1,324 animals. Bidirectional selective breeding for good and poor conditioning has produced, respectively, one population in which the percentage of animals showing good conditioning has increased over 25 generations from 19% to 77% and another in which it has decreased over 23 generations to 0%-4%. No increase in a measure of sensitization induced by an unconditioned stimulus (the central excitatory state) accompanied the increase in the percentage of good conditioners in the population selected for good conditioning, whose level of conditioned responding exceeds that of the sensitization measure.     

Discomfort with space and motion: A possible marker of vestibular dysfunction assessed by the situational characteristics questionnaire

Space and motion discomfort (SMD) refers to the situational specificity of symptoms occurring in some patients with vestibular dysfunction, such as those with balance disorders and some with panic disorder. SMD occurs in situations characterized by inadequate visual or kinesthetic information for normal spatial orientation. We report the results of two studies of the construct validity of the Situational Characteristics Questionnaire (SitQ), which has two subscales, both of which measure SMD: the SMD-I and SMD-II. In Study 1, the SitQ was administered to members of a self-help group for balance disorders, a psychiatric sample consisting of patients with panic disorder, nonpanic anxiety disorders, depression, and a sample of normals. SMD levels were the highest in the self-help balance group, next to the highest in the panic groups, and lowest in the remaining groups. In Study 2, the SitQ was administered to otolaryngological patients with vestibular dysfunction and to patients with hearing loss. SMD levels were higher in the vestibular patients. Data on internal consistency, test-retest reliability, and convergent and discriminant validity are presented. The SitQ, particularly the SMD-II, is recommended for quantifying space and motion discomfort in patients with anxiety and/or balance disorders.Study 1 was funded by MH 40757. Study 2 was funded by a grant from the Upjohn Company and MH 19816.     

Webers Idealtypus Als Methode Zur Bestimmung Des Begriffsinhaltes Theoretischer Begriffe in Den Kulturwissenschaften

Weber's Ideal Type as a Method of Forming the Content of Theoretical Concepts in Social Sciences}. Max Weber introduced the ideal type as the specific method of concept formation in social sciences. But the ideal type is not established in social research. Instead, authors in philosophy of science until today try to reconstruct and interpret what Weber said about ideal types as well as what might be their importance in Weber's social theory. The thesis of the following paper is that the difficulties in understanding Weber's ideal types are linked with Weber's intensional logic of concept formation. The thesis is defended in three steps. The first step deals with Weber's understanding of what is a scientific question in cultural sciences. Secondly Weber's critical arguments against positivism, hegelianism and historism are worked out. Thirdly, Weber's method of concept formation is reconstructed.     

Scham und Schuld – Sein und Tun

Shame and guilt are affective experiential dimensions regulating the different forms of being and behaving in a social context. Constructive or even pathologic feelings of guilt are to be distinguished from real guilt. Shame refers to the judgment of ?So-sein” even if being often manifests itself in action. Shame is generated by the ideal ego. Guilt and feelings of guilt are dimensions of acting, real guilt requires the recognition of guilt, guilt is generated by the superego (conscience). The implications of familiar as well as extreme traumatisation for shame and feelings of guilt are discussed. The most frequent wish for a therapy nowadays that offers perspectives of changes by action can be considered as a defence against processing of the being in psychoanalytical therapy.     

Positive affect and suicide ideation in older adult primary care patients

Suicide is a significant public health problem for older adults. Identification of protective factors associated with reduced risk is important. The authors examined the association of positive affect and suicide ideation in 462 primary care patients ages 65 and older. Positive affect distinguished suicide ideators from nonideators, after controlling for age, gender, depression, negative affect, illness burden, activity, sociability, cognitive functioning, and physical functioning. There was a trend toward age moderation of this relationship. Clinical and theoretical formulations of late-life suicide should consider the role of positive affect, including the possibility that its protective effects grow more pronounced with age.     

Körperinszenierungen

Zusammenfassung Formen zeitgenössischen Körperagierens in der Adoleszenz, wie besondere Haartracht (Punkfrisuren), Tätowierungen und Piercings, sowie pathologische Körpermanipulationen, wie Selbstverletzung und Essstörungen, haben eine auffallende Ähnlichkeit bzw. gehen parallel mit den Körperritualen der sog. Naturvölker, teilweise auch mit denen unseres eigenen Kulturkreises. Bei aller Ähnlichkeit sind jedoch drei in ihrem Wesen verschiedene Formen zu unterscheiden: 1. Die gesellschaftskonformen Körperpraktiken, die der Tradition einer sozialen Gruppe entsprechen und öffentlich-rituell Identitätsschritte in der menschlichen Entwicklung markieren (insbesondere Initiation in der Adoleszenz), wie wir es bei den Naturvölkern und in Rudimenten in unserer Kultur finden. 2. Die Benutzung des eigenen Körpers, um sich als Adoleszenter meist in Peer-Groups provozierend und rebellierend gegen überkommene Traditionen abzugrenzen; hier wird am Körper eine passagere Gegenidentifikation markiert, die gerade nicht den überkommenen Traditionen entspricht, jedoch wieder verlassen wird und in eine reife Erwachsenenidentität übergeht. 3. Die pathologischen Formen des Körperagierens dagegen bedeuten Entwicklungsstillstand und Arretierung der Identitätsentwicklung; sie müssen (wie eine Sucht) ständig wiederholt werden, um eine prekäre Ersatzidentität aufrechtzuerhalten, weil die Entwicklung einer autonomen Identität mit psychosenaher Trennungsangst verbunden wäre. Nur Menschen manipulieren derart ihren Körper, und zwar seit Menschengedenken, als ob der Mensch ständig symbolisch die Natur beherrschen müsste, wie auch sonst die natürliche Umwelt, in mehr oder weniger harmloser bzw. destruktiver Form, und der Körper ist der ihm nächste Teil der Natur.

Body enactmentsOn parallels between body acting of primitive cultures, contemporary adolescents and pathologic forms

There are obvious parallels between contemporary body acting of adolescents such as the manner of wearing ones hair, using tattoos and piercings, as well as some kinds of pathologic body manipulation (like self-inflicting or eating disorders), and ritual body performances of the so-called primitive or savage cultures. But in part there are also parallels with ubiquituous body activities in our culture. In this paper three groups of body-acting are distinguished: 1. In conformity to social rules traditional body practices are marking steps of identity development, for example rites of initiation in primitive cultures and rudimentary ceremonies in our culture. 2. Ones own body is used to define oneself in adolescence rebelliously against social traditions. Such unconventional body-acting occurs in peer-groups and is seen as a passagère phenomenon in average identity development. 3. Pathologic forms of self destructive body-acting signify a cessation of development. In an addiction-like repetition they build up a precarious identity surrogate, because arriving at an autonomous identity would be connected with psychotic separation anxiety. Only human beings are able to treat their bodies (in normality and pathology), as if humans are constantly compelled to dominate nature symbolically in every moment, and their bodies are the nearest part of nature to them.

Imagery and interpretations in social phobia: support for the combined cognitive biases hypothesis

Cognitive-behavioral models of clinical problems typically postulate a role for the combined effects of different cognitive biases in the maintenance of a given disorder. It is striking therefore that research has tended to examine cognitive biases in isolation rather than assessing how they work together to maintain psychological dysfunction. The combined cognitive biases hypothesis presented here suggests that cognitive biases influence each another and can interact to maintain a given disorder. Furthermore, it is proposed that the combined effects of cognitive biases may have a greater impact on sustaining a given disorder than if the biases operated in isolation. The combined cognitive biases hypothesis is examined in relation to imagery and interpretation in social phobia. Individuals with social phobia experience negative images of themselves performing poorly in social situations, and they also interpret external social information in a less positive way than those without social anxiety. Evidence of a reciprocal relationship between imagery and interpretations is presented, and the mechanisms underlying the combined effects are discussed. Clinical implications and the potential utility of examining the combined influence of other cognitive biases are highlighted.     

How informed is online informed consent?

We examined participants' reading and recall of informed consent documents presented via paper or computer. Within each presentation medium, we presented the document as a continuous or paginated document to simulate common computer and paper presentation formats. Participants took slightly longer to read paginated and computer informed consent documents and recalled slightly more information from the paginated documents. We concluded that obtaining informed consent online is not substantially different than obtaining it via paper presentation. We also provide suggestions for improving informed consent--in both face-to-face and online experiments.
