Resolving semantically induced tip-of-the-tongue states for proper nouns

Three experiments are reported in which tip-of-the-tongue states (TOTSs) were induced in subjects by reading them pieces of item-specific information. In Experiments 1 and 2, subjects attempted to name famous people. These experiments showed that, in a TOTS, seeing a picture of the face of the target person did not facilitate naming, whereas the initials of the person's name did. In Experiment 3, a similar result was obtained with a landmark-naming task. The results of the experiments are discussed with reference to current models of memory structure and name retrieval.     

Equivalent models in covariance structure analysis

Defining equivalent models as those that reproduce the same set of covariance matrices, necessary and sufficient conditions are stated for the local equivalence of two expanded identified modelsM ₁ andM ₂ when fitting the more restricted modelM ₀. Assuming several regularity conditions, the rank deficiency of the Jacobian matrix, composed of derivatives of the covariance elements with respect to the union of the free parameters ofM ₁ andM ₂ (which characterizes modelM ₁₂), is a necessary and sufficient condition for the local equivalence ofM ₁ andM ₂. This condition is satisfied, in practice, when the analysis dealing with the fitting ofM ₀, predicts that the decreases in the chi-square goodness-of-fit statistic for the fitting ofM ₁ orM ₂, orM ₁₂ are all equal for any set of sample data, except on differences due to rounding errors.This research was supported by the Foundation of Social-Cultural Sciences which is subsidized by the Dutch Scientific Organization (N.W.O.) under project number 500-278-003.

Ist es utopisch, sich zukünftige Psychoanalytiker ohne besondere berufliche Identität vorzustellen?

The subject of the Identity of Psychoanalysis and of its representatives belongs to the orthodox psychoanalytic movement. Since about 15 years, under the presidency of J. Sandler, the International Psychoanalytic Association (IPA) has tried successfully to facilitate scientific research and to promote projects. If the resistance of influential analysts against empirical investigations further decreases, psychoanalytic movement and its unfavourable concommitants will be past. The development to a scientific community will no longer be hampered by controversies on professional identity. The question of identity was dominated by the idea of the so-called “strict, untendentious psychoanalysis” (Freud 1909b, S. 104, 1919a, S. 168). It never existed and could never materialise—it was a fiction. The psychosocial dimensions and its normative implications call the concept of identity into question. Instead it is advisable to speak of a pychoanalytic attitude which has to prove its therapeutic value. This “second (professional) self” (Schafer 1983) is closely connected to the “first (personal) self”, but it is necessary and possible to separate the method from the person and to objectify changes in the patient even if taking place in an intersubjective, relational space. For many years Freud defined what Psychoanalysis is about and who is entitled to call himself an analyst. Later on, the psychoanalytic movement and the institutionalised training system fulfilled this role. The training analysis had been at the centre of all curricula. The genealogy of the training analyst determined the membership in the evergrowing family. Dissidents belong to the history of Psychoanalysis. The official acceptance of the pluralisms within the International Psychoanalytical Association demands comparisons between the various schools according to scientific criteria. Modern process and outcome research provides criteria suited to serve as a model for clinical treatment reports.     

Dilution as a model of long-term forgetting

This article presents a model of long term forgetting based on 3 ideas: (a) Memory for a stimulus can be described by a population of accessible traces; (b) probability of retrieval after a delay is predicted by the proportion of traces in this population that will be defined as correct if sampled; and (c) this population is diluted over time by null traces that, if accessed, block retrieval. Dilution is modeled as a linear function of time and outcome of accessing memories by their temporal organization. The model is applied to 5 published experiments studying forgetting in cued recall, 4 recognition experiments, and 1 using savings methods. The model specifies the different form of the retention function in each case well and provides a principled explanation for some puzzling characteristics of forgetting without recourse to mechanisms such as decay or consolidation.     

A Defence of Jury Nullification

In both Great Britain and the United States there has been a growing debate about the modern acceptability of jury nullification. Properly understood, juries do not have any constitutional right to ignore the law, but they do have the power to do so nevertheless. Juries that nullify may be motivated by a variety of concerns: too harsh sentences, improper government action, racism, etc. In this article, I shall attempt to defend jury nullification on a number of grounds. First, I discuss the use of general verdicts and reject their replacement in criminal trials by special verdicts. Second, I examine verdicts based upon mistakes and racial prejudice, turning my attention to perverse verdicts and the question of whether or not juries are guilty of legislating when nullifying the law. Finally, I look at the problem of the awarding of excessive damages by juries. My goal will be to provide a sound theoretical defence of the practice of jury nullification.R. Pound, Law in Books and Law in Action, American Law Review 44 (1910),18.The term jury nullification is synonymous with jury equity. The use of jury nullification has been suspected of playing a role in the infamous trials of O. J. Simpson and Rodney King in the last decade. See People v Simpson, No. BA097211 (Cal. Super. Ct. 1995); People v Powell, No. BA035498 (Cal. Super. Ct. 1991).     

Bilateral Transfer in Tapping Skill in the Absence of Peripheral Information

Bilateral transfer in a fast tapping task was investigated under normal (+FB) and reduced (-FB) feedback conditions, in the -FB experiment 36 Ss were assigned to 3 groups: preferred (PH) to non-preferred (NPH) shift; NPH to PH; and alternating trials of PH and NPH. With + FB 2 further groups of 12 Ss transferred PH to NPH or NPH to PH. 8 preshift and 8 postshift trials were given. The alternating group had 8 PH and 8 NPH trials. In preshift performance increment was found in ail groups except in +FB with NPH. With +FB some facilitation in transfer was obtained for the NPH; under -FB marked positive transfer was found for the PH. Alternating PH and NPH performance conformed to preshift levels. Results were discussed in terms of differential central control processes for the two hands.
