The correspondence between sentence production and corpus frequencies in modifier attachment

We examined the production of relative clauses in sentences with a complex noun phrase containing two possible attachment sites for the relative clause (e.g., "Someone shot the servant of the actress who was on the balcony."). On the basis of two corpus analyses and two sentence continuation tasks, we conclude that much research about this specific syntactic ambiguity has used complex noun phrases that are quite uncommon. These noun phrases involve the relationship between two humans and, at least in Dutch, induce a different attachment preference from noun phrases referring to non-human entities. We provide evidence that the use of this type of complex noun phrase may have distorted the conclusions about the processes underlying relative clause attachment. In addition, it is shown that, notwithstanding some notable differences between sentence production in the continuation task and in coherent text writing, there seems to be a remarkable correspondence between the attachment patterns obtained with both modes of production.     

Remembering and Remembering to Forget

To navigate our lives we all need to find ways both to remember and sometimes to forget aspects of our experiences that threaten us or cause us anxiety. Often patients need help in developing a capacity to hold in some dialectical tension, both remembering and forgetting. Some people are so frightened by the harsher realities of their lives that they turn to us to take on the remembering side of this dialectic, and, sometimes, to take on the forgetting side. Part of the work of their therapy is to help them develop the capacity to do more of both for themselves. Other patients come better prepared to take on this challenge and use us to witness and support their own efforts. This paper considers how patients use their hours with us to remember and to forget and ways in which psychoanalysts might participate in this undertaking.     

Expertise du comité d’hygiène sécurité et conditions de travail : une conception si extensive du secret médical qu’elle pourrait entraîner la négation du droit du travail

Paid medical institutions which are entitled to work conditions corresponding to the respect of their basic right with which it must be articulated. Which is the exact extent of the medical secret? Can it go until allowing the neutralization of the right of the workers organisms?     

Apology as Self-Repair

Bernard Williams (1981) briefly discusses agent regret in his broader account of moral luck. The present paper first outlines one way to develop Williams’s notion with reference to the unintended harm; it then suggests that agent regret can be counteracted by externalizing the action that caused unintended harm, in Harry Frankfurt’s (1988a, b) sense of externalization; and then the present paper argues that apology is a mechanism by which a person can externalize an offending action/effect—in that way counteracting agent regret (and possibly, though this is a further empirical point not defended here, mitigating the psychological effects). This function for apology—self-repair—is different from others described in the literature, which address the role of apology in repairing relationships. The present paper describes a nonfictional example, that of a veteran of the U.S. war in Iraq who contacts a family gravely injured by him and his combat unit; the veteran is motivated to contact the family to apologize. The example serves as a prototypical case of agent regret. The example is taken from a recent literature on the clinical psychology of (what that literature calls) self-inflicted “moral injury”; categorizing this example of moral injury as agent regret also helps broaden our understanding of moral injury as a philosophical category and as a psychological phenomenon.     

Analyzing the kinematics of hand movements in catching tasks—An online correction analysis of movement toward the target’s trajectory

Free, 3-D interceptive movements are difficult to visualize and quantify. For ball catching, the endpoint of a movement can be anywhere along the target’s trajectory. Furthermore, the hand may already have begun to move before the subject has estimated the target’s trajectory, and the subject may alter the targeted position during the initial part of the movement. We introduce a method to deal with these difficulties and to quantify three movement phases involved in catching: the initial, non-goal-directed phase; the goal-directed phase, which is smoothly directed toward the target’s trajectory; and the final, interception phase. Therefore, the 3-D movement of the hand was decomposed into a component toward the target’s trajectory (the minimal distance of the hand to the target’s parabolic [MDHP] trajectory) and a component along this trajectory. To identify the goal-directed phase of the MDHP trajectory, we employed the empirical finding that goal-directed trajectories are minimally jerky. The second component, along the target’s trajectory, was used to analyze the interaction of the hand with the ball. The method was applied to two conditions of a ball-catching task. In the manipulated condition, the initial part of the ball’s flight was occluded, so the visibility of the ball was postponed. As expected, the onset of the smooth part of the movement shifted to a later time. This method can be used to quantify anticipatory behavior in interceptive tasks, allowing researchers to gain new insights into movement planning toward the target’s trajectory.     

Synaptic tagging, evaluation of memories, and the distal reward problem

Long-term synaptic plasticity exhibits distinct phases. The synaptic tagging hypothesis suggests an early phase in which synapses are prepared, or "tagged," for protein capture, and a late phase in which those proteins are integrated into the synapses to achieve memory consolidation. The synapse specificity of the tags is consistent with conventional neural network models of associative memory. Memory consolidation through protein synthesis, however, is neuron specific, and its functional role in those models has not been assessed. Here, using a theoretical network model, we test the tagging hypothesis on its potential to prolong memory lifetimes in an online-learning paradigm. We find that protein synthesis, though not synapse specific, prolongs memory lifetimes if it is used to evaluate memory items on a cellular level. In our model we assume that only "important" memory items evoke protein synthesis such that these become more stable than "unimportant" items, which do not evoke protein synthesis. The network model comprises an equilibrium distribution of synaptic states that is very susceptible to the storage of new items: Most synapses are in a state in which they are plastic and can be changed easily, whereas only those synapses that are essential for the retrieval of the important memory items are in the stable late phase. The model can solve the distal reward problem, where the initial exposure of a memory item and its evaluation are temporally separated. Synaptic tagging hence provides a viable mechanism to consolidate and evaluate memories on a synaptic basis.     

Neural activity,neural connectivity,and the processing of emotionally valenced information in older adults: links with life satisfaction

This study examines whether differences in late-life well-being are linked to how older adults encode emotionally valenced information. Using fMRI with 39 older adults varying in life satisfaction, we examined how viewing positive and negative images would affect activation and connectivity of an emotion-processing network. Participants engaged most regions within this network more robustly for positive than for negative images, but within the PFC this effect was moderated by life satisfaction, with individuals higher in satisfaction showing lower levels of activity during the processing of positive images. Participants high in satisfaction showed stronger correlations among network regions—particularly between the amygdala and other emotion processing regions—when viewing positive, as compared with negative, images. Participants low in satisfaction showed no valence effect. Findings suggest that late-life satisfaction is linked with how emotion-processing regions are engaged and connected during processing of valenced information. This first demonstration of a link between neural recruitment and late-life well-being suggests that differences in neural network activation and connectivity may account for the preferential encoding of positive information seen in some older adults.     

Neural and behavioral effects of interference resolution in depression and rumination

Individuals diagnosed with major depressive disorder (MDD) often ruminate about their depression and their life situations, impairing their concentration and performance on daily tasks. We examined whether rumination might be due to a deficit in the ability to expel negative information from short-term memory (STM), and fMRI was used to examine the neural structures involved in this ability. MDD and healthy control (HC) participants were tested using a directed-forgetting procedure in a short-term item recognition task. As predicted, MDD participants had more difficulty than did HCs in expelling negative, but not positive, words from STM. Overall, the neural networks involved in directed forgetting were similar for both groups, but the MDDs exhibited more spatial variability in activation in the left inferior frontal gyrus (a region critical for inhibiting irrelevant information), which may contribute to their relative inability to inhibit negative information.
