Three studies examined effects of different response measures on spatial updating during self-rotation. In Experiment 1, participants located objects in an array with a pointer after physical self-rotation, imagined self-rotation, and a rotation condition in which they ignored superfluous sensorimotor signals. In line with previous research, updating performance was found to be superior in the ...

We present a formal, logical framework for the representation and analysis of an expressive class of authorization and obligation policies. Basic concepts of the language and operational model are given, and details of the representation are defined, with an attention to how different classes of policies can be written in our framework. We show how complex dependencies amonst policy rules can b...

The functional and anatomical organization of the cingulate cortex across primate species is the subject of considerable and often confusing debate. The functions attributed to the midcingulate cortex (MCC) embrace, among others, feedback processing, pain, salience, action-reward association, premotor functions, and conflict monitoring. This multiplicity of functional concepts suggests either u...

Five experiments examined the relearning of words, simple line-drawing pictures, and complex photographic pictures after retention intervals of 1 to 10 weeks. For those items that were neither recalled nor recognized, the identical item was relearned better than an unrelated control item, as measured by a recall test following relearning. This relearning advantage in recall held for all three c...

.We previously re~rted th~t ra~s wer~ able to discriminate among two, three, and four sequentu~lly presented auditory stimuli (DaVIS & Albert, 1986). In the present paper, we describe our failure to transfer this numerical discrimination to visual stimuli and to establish the same discn.nnnation. using visual sti.muli i~ naive animals. These negative results conflict with sporadic evidence of l...

Saul Kripke’s thesis that ordinary proper names are rigid designators is supported by widely shared intuitions about the occurrence of names in ordinary modal contexts. By those intuitions names are scopeless with respect to the modal expressions. That is, sentences in a pair like (a) Aristotle might have been fond of dogs (b) Concerning Aristotle, it is true that he might have been fond of dog...

The anterior cingulate cortex (ACC) has long been thought to regulate conflict between an object of attention and distractors during goal-directed sustained attention. However, it is unclear whether ACC serves to sustained attention itself. Here, we developed a task in which the time course of sustained attention could be controlled in rats. Then, using pharmacological lesion experiments, we em...

Dance/movement therapy (DMT) interventions, if designed to promote cultural relevance and community ownership, may enhance healing among African adolescent survivors of war and organised violence. The author posits a theoretical rationale for body movement-based approaches to psychosocial rehabilitation, and offers DMT's holism as evidence of transcultural applicability. Two distinct DMT iniati...

Speaking is a physiological process that manifests in the acoustic and in the optic domain and hence is audible and visible. These two modalities influence each other in perception. Under normal circumstances the speech information in both channels is coherent and complementary and integrated to a percept. But if the information is conflicting and nevertheless integrated then the percept in one...
