Inhibitory deficits in older adults: list-method directed forgetting revisited

In list-method directed forgetting, participants are cued to intentionally forget a previously studied list while remembering a subsequently presented 2nd list. Results from prior research are inconclusive on whether older adults show deficits in this type of task. In 3 experiments, the authors reexamined the issue and compared younger and older adults' responsiveness to the forget cue. Across the experiments, the forget cue was varied within and between participants, the 2 lists were unrelated and related to each other, and recall of the lists was required simultaneously and successively. In none of the 3 experiments did any age-related difference in directed forgetting performance emerge. List-method directed forgetting is assumed to reflect retrieval inhibition. The present results thus challenge the proposal of a general inhibitory deficit in older adults' memory performance.     

How are inflectional affixes organized in the mental lexicon?: evidence from the investigation of agreement errors in agrammatic aphasics

Recent psycholinguistic studies have provided evidence that regularly inflected words are decomposed into stems and affixes, both of which have their own representations in the mental lexicon. Specific models of the lexical organization of inflectional affixes have, however, only rarely been investigated in psycho- or neurolinguistic work. We test two recently proposed theoretical models: a representation of affixes (i) in default inheritance trees (Corbett and Fraser, 1993) and (ii) in underspecified paradigms (Wunderlich, 1996). Based on an analysis of agreement errors in elicited speech-production data of German agrammatic aphasics, we argue that affixes are organized with respect to the morphosyntactic features they encode. Specifically, our data indicate that inflectional affixes are best captured within an underspecified paradigm.     

Inflectional morphology in German Williams syndrome

In a recent paper, Clahsen and Almazan (1998) reported a dissociation between unimpaired regular and impaired irregular past tense morphology in English Williams syndrome (WS). Our aim is to investigate whether these findings carry over to another language with different morphological systems. We present data on regular and irregular participles and noun plurals from 2 German WS subjects and 10 controls matching in mental age. For noun plurals, regular morphology is intact in WS, whereas irregular forms are impaired. A similar dissociation is observed for participles: while regular inflection is unimpaired, WS subjects, unlike controls, apply the regular suffix incorrectly to frequent irregular verbs. We discuss our findings against the current debate between connectionist and dualistic approaches to the language faculty.     

The Nudity of the Ego. An Eckhartian Perspective on the Levinas/Derrida Debate on Alterity

The present paper examines the Eckhartian motives in Derrida's critique of Levinas’ concept of the “Other”. The focus is put on the Husserlian concept of alter ego that is at the core of the debate between Levinas and Derrida. Against Levinas, Derrida argues that alter is not an epithet that expresses a mere accidental modification of the ego, but an indicator of radical exteriority. Interestingly enough, this position is virtually identical with Meister Eckhart's interpretation of the famous proposition from Exodus 3:14 “I am who I am”. Eckhart claims that the pronoun ego denotes the absolutely simple substance of the uncreated intellect, which can, by definition, never receive any accidental determination whatsoever. The reduplication of the “I am” is by no means tautological, but expresses the intra-divine dynamic of the Father who engenders the Son as his perfect equal and alter ego. This transcendental conception of egoity also governs the relationships between human beings: the ethical encounter with the “Other” requires that we consider them not primarily in their empirical, contingent existence but in the transcendental purity of their indeclinable ego, which is identical with the incessant act in which God knows himself in the Son as his absolutely Other. Thus, Meister Eckhart's approach proves, against Levinas, that it is possible to develop an “egological” philosophy that avoids the pitfalls of a naturalistic and potentially violent ontology of the subject.
