The recovering female alcoholic: A family affair

Supported by a review of relevant literature and a case study, the author argues that family therapy intervention enhances the likelihood of a female alcoholic's positive prognosis. With a basis in systems theory, family therapy views the family as a system and, hence, perceives the alcoholism as a symptom of that family. A profile of the female alcoholic, how her drinking affects her family, and the role that family therapy plays in the recovery process are examined.     

Self-organizing continuous attractor network models of hippocampal spatial view cells

Single neuron recording studies have demonstrated the existence of hippocampal spatial view neurons which encode information about the spatial location at which a primate is looking in the environment. These neurons are able to maintain their firing even in the absence of visual input. The standard neuronal network approach to model networks with memory that represent continuous spaces is that of continuous attractor networks. It has recently been shown how idiothetic (self-motion) inputs could update the activity packet of neuronal firing for a one-dimensional case (head direction cells), and for a two-dimensional case (place cells which represent the place where a rat is located). In this paper, we describe three models of primate hippocampal spatial view cells, which not only maintain their spatial firing in the absence of visual input, but can also be updated in the dark by idiothetic input. The three models presented in this paper represent different ways in which a continuous attractor network could integrate a number of different kinds of velocity signal (e.g., head rotation and eye movement) simultaneously. The first two models use velocity information from head angular velocity and from eye velocity cells, and make use of a continuous attractor network to integrate this information. A fundamental feature of the first two models is their use of a 'memory trace' learning rule which incorporates a form of temporal average of recent cell activity. Rules of this type are able to build associations between different patterns of neural activities that tend to occur in temporal proximity, and are incorporated in the model to enable the recent change in the continuous attractor to be associated with the contemporaneous idiothetic input. The third model uses positional information from head direction cells and eye position cells to update the representation of where the agent is looking in the dark. In this case the integration of idiothetic velocity signals is performed in the earlier layer of head direction cells.     

Novel visual stimuli activate a population of neurons in the primate orbitofrontal cortex

Neurons were found in the rhesus macaque anterior orbitofrontal cortex that respond to novel but not to familiar visual stimuli. Some of these neurons responded to all novel stimuli, and others to only a subset (e.g., to novel faces). The neurons have no responses to familiar reward- or punishment-associated visual stimuli, nor to taste, olfactory or somatosensory inputs. The responses of the neurons typically habituated with repeated presentations of a novel stimulus, and five presentations each 1s was the median number for the response to reach half-maximal. The neurons did not respond to stimuli which had been novel and shown a few times on the previous day, indicating that the neurons were involved in long-term memory. The median latency of the neuronal responses was 120 ms. The median spontaneous firing rate was 1.3 spikes/s, and the median response to novel visual stimuli was 6.0 spikes/s. These findings indicate that the long-term memory for visual stimuli is information that is represented in a region of the primate anterior orbitofrontal cortex.     

Camus’s Algerian in Paris: A Prose Poetic Reading of <Emphasis Type="Italic">L’Étranger</Emphasis>

This paper demonstrates that L'étranger, Camus's famous novel about an outsider, had by as early as 1946 become just as much of an 'insider' in terms of its affiliation to the Parisian literary tradition. More than an insider simply by virtue of its contemporary place in the French canon, then, the novel is also intertextually bound to a tradition of oxymoronic poetics dating back to Charles Baudelaire's Paris Spleen (Les Petits poèmes en prose). I shall examine the way in which L'étranger performs its prose poetics, thereby establishing it as exemplary of a Parisian model of modernity. Additionally, the famous scene on the beach will be considered as a liminal space and as a literary translation of Paris into the desert, which, once a joke for Paris's relationship to provincial France, became after the Second World War a new allegory for the capital's self-alterity.     

A Unified Empirical Account of Responsibility Judgments*

Skeptical worries about moral responsibility seem to be widely appreciated and deeply felt. To address these worries—if nothing else to show that they are mistaken—theories of moral responsibility need to relate to whatever concept of responsibility underlies the worries. Unfortunately, the nature of that concept has proved hard to pin down. Not only do philosophers have conflicting intuitions; numerous recent empirical studies have suggested that both prosaic responsibility judgments and incompatibilist intuitions among the folk are influenced by a number of surprising factors, sometimes prompting apparently contradictory judgments. In this paper, we show how an independently motivated hypothesis about responsibility judgments provides a unified explanation of the more important results from these studies. According to this ‘Explanation Hypothesis’, to take an agent to be morally responsible for an event is to take a relevant motivational structure of the agent to be part of a significant explanation of the event. We argue that because of how explanatory interests and perspectives affect what we take as significant explanations, this analysis accounts for the puzzling variety of empirical results. If this is correct, the Explanation Hypothesis also provides a new way of understanding debates about moral responsibility.     

Top-down control of visual perception: attention in natural vision

Top-down perceptual influences can bias (or pre-empt) perception. In natural scenes, the receptive fields of neurons in the inferior temporal visual cortex (IT) shrink to become close to the size of objects. This facilitates the read-out of information from the ventral visual system, because the information is primarily about the object at the fovea. Top-down attentional influences are much less evident in natural scenes than when objects are shown against blank backgrounds, though are still present. It is suggested that the reduced receptive-field size in natural scenes, and the effects of top-down attention contribute to change blindness. The receptive fields of IT neurons in complex scenes, though including the fovea, are frequently asymmetric around the fovea, and it is proposed that this is the solution the IT uses to represent multiple objects and their relative spatial positions in a scene. Networks that implement probabilistic decision-making are described, and it is suggested that, when in perceptual systems they take decisions (or 'test hypotheses'), they influence lower-level networks to bias visual perception. Finally, it is shown that similar processes extend to systems involved in the processing of emotion-provoking sensory stimuli, in that word-level cognitive states provide top-down biasing that reaches as far down as the orbitofrontal cortex, where, at the first stage of affective representations, olfactory, taste, flavour, and touch processing is biased (or pre-empted) in humans.     

Kids and Teens in Court (KTIC): A Model for Preparing Child Witnesses for Court

Each year, numerous children testify in the United States in either criminal, civil, or juvenile court cases. Typically, children who testify are alleged victims of sexual or physical abuse or neglect, witnesses to violent crime, or subjects in custodial hearings in civil court. As more maltreatment cases are prosecuted and child custody is contested, an increasing number of children are being called as witnesses in court. Many of these children have already been traumatized by the experiences that led to their need to testify, and participation in the court process can have additional negative effects. This article describes the development and recent formative evaluation of a court preparation program that provides psychoeducation and utilizes components of evidence-based trauma treatment approaches, such as relaxation and in vivo exposure, to support child witnesses and reduce the risk of retraumatization. Children and adolescents participating in the program attend group sessions conducted by mental health clinicians and complete a court-related anxiety measure before and after each session. Results from 175 participants are reported. Findings indicated significant decreases in court-related anxiety with large program effects. Challenges encountered by the program and future directions are discussed.
