Measures of temporal discrimination in fixed-interval performance: a case study in archiving data.

The primary data of many experimental studies of animal learning and performance consist of the times at which stimuli and reinforcers were delivered, and the times at which responses occurred. The articles based on most of these studies report selected data, either from some sessions or some animals, or summary measures of the animals' behavior. The primary data are sufficient to produce any of the selected and summary measures, but the selected and summarized data cannot produce many of the measures used in other experimental reports. It is now feasible to archive the primary data from animal behavior experiments so that they are accessible for others to perform secondary analysis. The value of such secondary analysis of archived data is described with a case study in which rats were trained on three fixed-interval schedules of reinforcement.

Unplanned pregnancy and risk of maternal depression: secondary data analysis from a prospective pregnancy cohort

Purpose: to evaluate the relationship between unplanned pregnancy (UP), a common problem in high and low income countries and maternal depression (MD). Methods: Secondary analysis of data from a prospective cohort study with pregnant women recruited from 10 primary care clinics of the public sector in São Paulo, Brazil. Participants were questioned about pregnancy intention at 20–30 weeks of gestation. The Self Report Questionnaire score >7 was used to evaluated the presence of depression during pregnancy and 11 months after childbirth. Four groups of MD were defined: never; antenatal only; postnatal only; persistent (both antenatal/postnatal). Multinomial logistic regression was used to assess the relationship between UP and MD, controlling for confounding. Results: Data were analysed for 701 at the postpartum period. Five hundred and sixty-two (67.8%) women did not plan the pregnancy. Women with UP had 2.5 more risk of being depressed during both assessments (during pregnancy and postpartum) when compared to women with a planned pregnancy (RR: 2.5; 95% CI: 1.47:4.30). In the adjusted models, women with UP were significantly more likely to have persistent depression (RR: 2.3; 95% CI: 1.2:4.3). Conclusion: UP is an independent risk factor for persistent depression, but not for postpartum depression     

Human biological and nonbiological point-light movements: Creation and validation of the dataset

Human action perception is so powerful that people can identify movement efficiently in the absence of pictorial information, such as in point-light displays. Interest is growing in this type of stimulus for research in neuroscience. This interest stems from the advantage of separating the component of pure human action kinematics from other pictorial information, such as facial expression and muscle contraction. Although several groups have previously developed datasets of human point-light actions, due to the lack of datasets composed of daily actions with short durations, we developed 20 biological and 40 control (scrambled) point-light movements by using the technique of recording people wearing reflector patches. The videos are about 1 s long. Subsequently, we performed a judgment task in which 100 participants (50 male and 50 female) evaluated each video according to three categories: human action resemblance, performed action, and gender of actor. We present the mean scores of each evaluation for each video, and further propose a selection of the most suitable videos to be used as human point-light action displays and scrambled point-light displays for control. Finally, we discuss our findings on the gender attributions of the point-light displays.     

The morality of harm

In this article, we discuss the range of concerns people weigh when evaluating the acceptability of harmful actions and propose a new perspective on the relationship between harm and morality. With this aim, we examine Kelly, Stich, Haley, Eng and Fessler’s [Kelly, D., Stich, S., Haley, K., Eng, S., & Fessler, D. (2007). Harm, affect, and the moral/conventional distinction. Mind and Language, 22, 117-131] recent claim that, contrary to Turiel and associates, people do not judge harm to be authority independent and general in scope in the context of complex harmful scenarios (e.g., prisoner interrogation, military training). In a modified replication of their study, we examined participants’ judgments of harmful actions in these contexts by taking into account their explanations for their judgments. We claim that both in terms of participants’ judgments and rationales, the results largely confirm our hypothesis that actions involving harm andinjustice or rights violation are judged to be authority independent and general in scope, which is a modification of Turiel’s traditional hypothesis.     

Cerebellum and processing of negative facial emotions: Cerebellar transcranial DC stimulation specifically enhances the emotional recognition of facial anger and sadness

Some evidence suggests that the cerebellum participates in the complex network processing emotional facial expression. To evaluate the role of the cerebellum in recognising facial expressions we delivered transcranial direct current stimulation (tDCS) over the cerebellum and prefrontal cortex. A facial emotion recognition task was administered to 21 healthy subjects before and after cerebellar tDCS; we also tested subjects with a visual attention task and a visual analogue scale (VAS) for mood. Anodal and cathodal cerebellar tDCS both significantly enhanced sensory processing in response to negative facial expressions (anodal tDCS, p=.0021; cathodal tDCS, p=.018), but left positive emotion and neutral facial expressions unchanged (p>.05). tDCS over the right prefrontal cortex left facial expressions of both negative and positive emotion unchanged. These findings suggest that the cerebellum is specifically involved in processing facial expressions of negative emotion.     

Perversion on the other side of the couch

Abstract

Taking as his starting point the fact that, according to Freudian theory, perversion is inherent to the human being, the author focuses upon an aspect of perversion that has been little discussed: perversion on the other side of the couch, and thereby questions of how, in psychoanalytic theoretical and clinical practice, perverted drive motions may be presented. Such a phenomenon takes various forms: actually being enacted with patients; using psychoanalytic theory as a normative rule; the individual choice of profession and so forth. To exemplify his point of view, the author presents four different expressions of sexuality in Freudian theory: genital sexuality, perverted sexuality, the sexuality of the Ideals and narcissistic sexuality. After differentiating these four sexual expressions, the author shows how each of them may generate perversion in both clinical and theoretical psychoanalysis.

Ceccarelli P Perversion auf der anderen Seite der Couch

Indem er als Ausgangspunkt die Tatsache nimmt, daß entsprechend der Freudianischen Theorie Perversion dem menschlichen Sein inhärent ist, fokussiert der Autor auf einen Aspekt der Perversion, der wenig diskutiert wurde: Perversion auf der anderen Seite der Couch und damit Fragen, wie in der psychoanalytischen und klinischen Praxis pervertierte Triebbewegungen dargestellt werden können. Ein solches Phänomen zeigt sich in verschiedenartigen Formen: tatsächlich mit Patienten in Szene gesetzt; im Gebrauch psychoanalytischer Theorie als einer normativen Regel; die individuelle Wahl des Berufs und so weiter. Um seinen Standpunkt zu exempifizieren, stellt der Autor vier verschiedene Ausdrücke von Sexualität in der Freudianischen Theorie dar: genitale Sexualität; perverse Sexiualität; die Sexualität der Ideale; und narzißtische Sexualität. Nach einer Differenzierung dieser vier Ausdrücke für Sexualität zeigt der Autor, wie jeder von ihnen Perversion in klinischer und theoretischer Psychoanalyse generieren kann.

Ceccarelli P. Perversión del otro lado del diván.

Tomando como punto de partida el hecho de que de acuerdo a la teoría Freudiana la perversión es inherente al ser humano, el autor se enfoca en un aspecto de la perversión que ha sido muy poco discutido: la perversión del otro lado del diván, se pregunta cómo en la práctica psicoanalítica clínica y teórica, algunos impulsos pervertidos pueden estar presentes. Un fenómeno así puede tomar diversas formas: pasos al acto con pacientes, usar la teoría psicoanalítica como regla normativa, la elección individual de profesión y así. Para ejemplificar su punto de vista, el autor presenta cuatro diferentes expresiones de la sexualidad en la teoría freudiana: la sexualidad genital, sexualidad pervertida, la sexualidad de los Ideales, y la sexualidad narcisista. Además de diferenciar estas cuatro expresiones sexuales, el autor demuestra como cada una de estas formas puede generar perversión en el psicoanálisis clínico y teórico.     

Anomalous spin diffusion in 3He films: Expected behaviour in two-dimensional Fermi liquids

It is shown that the recently observed and unexplained behaviour for spin diffusion in ³He films can be understood in terms of the Fermi-liquid theory, provided that non-perturbative effects characteristic of two dimensions are taken into account. It is conjectured that such a behaviour suggests the onset of a regime in which spin current is conserved.
