Extinction of conditioned inhibition through nonreinforced presentation of the inhibitor

In previous studies that have tried to extinguish conditioned inhibition through nonreinforced presentations of the inhibitor, researchers have repeatedly failed to find evidence for such extinction. The present study revealed that extinction can be achieved through nonreinforcement of the inhibitor, depending on properties of the reinforcer. In a human causal learning experiment, we found complete extinction in a scenario in which the reinforcer could take on negative values. Thereby, this scenario reflected the assumed symmetrical continuum on which associative strength can vary, according to the Rescorla-Wagner theory of associative learning. In contrast to this, the inhibitory cue retained its inhibitory potential in another condition, in which the scenario did not allow negative values of the reinforcer. nt]mis|Klaus G.

The Comorbidity of Conduct Problems and Depression in Childhood and Adolescence

An extensive body of research documents the high prevalence of comorbidity among child and adolescent disorders in general and between conduct problems and depression in particular. These problems co-occur at significantly higher rates than would be expected by chance and their comorbidity may have significant implications for nosology, treatment, and prognosis. Four main hypotheses have been put forth to account for these high rates of comorbidity. First, comorbidity may be a result of shortcomings associated with referral or informant biases. Second, comorbidity may be an artifact of overlapping definitional criteria. Third, one disorder may cause the other disorder by influencing the developmental trajectory and placing an individual at increased risk for further difficulties. Finally, comorbidity between two disorders may be explained by shared underlying causal or risk factors. The purpose of this review is to explore these possibilities, concentrating primarily on the common risk factors of parent psychopathology, emotion regulation, and cognitive biases that may underlie the co-occurrence of these two disorders. Based on our review, we propose a model for the development of comorbidity between these two disorders.     

The development of perceptual sensitivity to second-order facial relations in children

This study investigated children’s perceptual ability to process second-order facial relations. In total, 78 children in three age groups (7, 9, and 11 years) and 28 adults were asked to say whether the eyes were the same distance apart in two side-by-side faces. The two faces were similar on all points except the space between the eyes, which was either the same or different, with various degrees of difference. The results showed that the smallest eye spacing children were able to discriminate decreased with age. This ability was sensitive to face orientation (upright or upside-down), and this inversion effect increased with age. It is concluded here that, despite early sensitivity to configural/holistic information, the perceptual ability to process second-order relations in faces improves with age and constrains the development of the face recognition ability.     

Why is Cheating Wrong?

Since cheating is obviously wrong, arguments against it (it provides an unfair advantage, it hinders learning) need only be mentioned in passing. But the argument of unfair advantage absurdly takes education to be essentially a race of all against all; moreover, it ignores that many cases of unfair (dis)advantages are widely accepted. On the other hand, the fact that cheating can hamper learning does not mean that punishing cheating will necessarily favour learning, so that this argument does not obviously justify sanctioning cheaters.     

Reply to Commentaries by Dodi Goldman and Avgi Saketopoulou

In this newly fashioned dialogue that allows us three respondents to continue our first-round discussions, I treasure the opportunity of learning more about Farhi's and Milner's works through the lenses of Dodi Goldman and Avgi Saketopoulou. Both respondents bring additional important historical information to this virtual roundtable, giving me another chance of re-reading Farhi's text through these new perspectives. I think that Goldman's information about Milner's interest in the natural science contributes a great deal to my understanding of her amazing capacity to tolerate her patient's changing psychotic states. I also learn a lot from Saketopoulou's sensitive discussion of the patient's last phone call to Milner shortly before her death in which the patient informs Milner that she had failed her in similar ways as Winnicott had failed Milner. I suggest a slightly different reading of the word failure and propose that the patient's utterance was a sign of a renewed strength rather than a statement of utter disappointment. A discussion of the place of phantasy in the intra-uterine life of a baby is also included in my response.     

Making a Memorial Place: The Photography of Shimon Attie

Assisting the analysand in making the past a living present held within a bearable yet unpredictable future is what psychoanalysis is so much about. Events of the past can never be redone, or fully repossessed, but they must be reconstructed in the context of the transference–countertransference experience of the analytic relationship. In order to make the past a useful present and presence, we need metaphors to give it shape—metaphors that capture the memorial activity linking the past with the present and future in a meaningful manner. In this paper, I explore the ways in which the work of the American photographer Shimon Attie creates a memorial place in which the past is not simply remembered but instead is actively mourned. In The Writing on the Wall, Attie collects broken fragments from prewar German-Jewish life in Berlin, and, by projecting these found shards of former lives onto the buildings in the Berlin Scheunenviertel, which once housed these people, he creates a potential space in which a present can suddenly come alive by the superimposition of a past that was supposed to have been obliterated. In this transitional realm, the spectator is given a wide realm of to-and-fro movements between past and present that permits the creation of an object world that did not exist before. I suggest that Attie's intricate weavings of past, present, and future serve as instructive models for the psychoanalytic process in which the analyst can find himself in a similar position of opening up a playground where the past can be brought into the present and where the presentness of the past can come alive. The ability to move back and forth between the present and the past suggests a link to the Freudian concept of deferred action, later taken up by Lacan under the notion of après-coup, where the impression (Prägung) of an earlier event, having lain dormant for a long time, breaks through into the present through a retroactive action that then completely reshapes the present impression. I draw comparisons to psychoanalytic practice, in which the superimposition (the stacking on top of one another) of recollections, dreams, and associations pries open in the analysand's mind a psychic space in which memories of a seemingly insignificant past absorb a sudden sense of urgency when revisited through this retroactive process.
