Age differences in implicit memory: More apparent than real

Elderly subjects and a group of young subjects identified fragmented picture sequences under conditions of focused attention. Two other groups of young subjects carried out this task under divided-attention conditions. Implicit memory, as measured by item-specific savings, was found in all groups, but this effect was smaller in the elderly group. The young subjects, but not elderly subjects, performed better on new items. The divided-attention conditions equated recall and recognition by the young and the elderly, but only the young subjects showed greater savings for recalled items. The elderly subjects’ reduced implicit memory therefore stemmed from their inability to facilitate implicit memory with explicit memory. A second experiment, involving only young subjects tested after delay, produced findings similar to those for the young divided-attention subjects. Implicit memory, as measured by savings in picture completion, does not show an age-related change when the role of explicit memory is considered. Age does, however, reduce skill learning.     

Rosser orderings and free variables

It is shown that for arithmetical interpretations that may include free variables it is not the Guaspari-Solovay system R that is arithmetically complete, but their system R ^–. This result is then applied to obtain the nonvalidity of some rules under arithmetical interpretations including free variables, and to show that some principles concerning Rosser orderings with free variables cannot be decided, even if one restricts oneself to usual proof predicates.     

On the differential nature of implicit and explicit memory

In this article, we report two experiments that provide further evidence concerning the differential nature of implicit and explicit memory. In Experiment 1, subjects first undertook a sentenceverification task. While carrying out this task, half of the subjects were also required to carry out a secondary processing task involving tone monitoring. Twenty-four hours later, the subjects’ memory for target items in the sentence-verification task was tested explicitly by means of a recognition task and implicitly by examining the extent to which the items primed fragment completion. Recognition performance was significantly impaired by the imposition of secondary processing demands during the original learning phase. In contrast, fragment completion was completely unaffected by this additional processing, even though substantial priming was observed. In Experiment 2, we examined whether priming in fragment completion is influenced by the nature of repetition during initial learning. Subjects studied a list of target items that were each repeated twice. Halfthe items were repeatedimmediately (lag 0) and halfwere repeated after six intervening items (lag 6). Memory for the itemswas assessed by recognition and by priming in fragment completion. Recognition was affected by lag, with lag 6 items being recognized better than lag 0 items. However, although significant priming was obtained, the extent of this priming was uninfluenced by lag. These data indicate two additional dimensions along which implicit and explicit memory differ and, furthermore, they support recent conceptualizations of processing differences underlying these two forms of memory.     

Engagement and suffering in responsible caregiving: On overcoming maleficience in health care

The thesis of this article is that engagement and suffering are essential aspects of responsible caregiving. The sense of medical responsibility engendered by engaged caregiving is referred to herein as ‘clinical phronesis,’ i.e. practical wisdom in health care, or, simply, practical health care wisdom. The idea of clinical phronesis calls to mind a relational or communicative sense of medical responsibility which can best be understood as a kind of ‘virtue ethics,’ yet one that is informed by the exigencies of moral discourse and dialogue, as well as by the technical rigors of formal reasoning. The ideal of clinical phronesis is not (necessarily) contrary to the more common understandings of medical responsibility as either beneficence or patient autonomy — except, of course, when these notions are taken in their “disengaged” form (reflecting the malaise of “modern medicine”). Clinical phronesis, which gives rise to a deeper, broader, and richer, yet also to a more complex, sense than these other notions connote, holds the promise both of expanding, correcting, and perhaps completing what it currently means to be a fully responsible health care provider. In engaged caregiving, providers appropriately suffer with the patient, that is, they suffer the exigencies of the patient's affliction (though not his or her actual loss) by consenting to its inescapability. In disengaged caregiving — that ruse Katz has described as the ‘silent world of doctor and patient’ — provides may deny or refuse any ‘given’ connection with the patient, especially the inevitability of the patient's affliction and suffering (and, by parody of reasoning, the inevitability of their own. When, however, responsibility is construed qualitatively as an evaluative feature of medical rationality, rather than quantitatively as a form of ‘calculative reasoning’ only, responsibility can be viewed more broadly as not only a matter of science and will, but of language and communication as well — in particular, as the task of responsibly narrating and interpreting the patient's story of illness. In summary, the question is not whether phronesis can ‘save the life of medical ethics’ — only responsible humans can do that! Instead, the question should be whether phronesis, as an ethical requirement of health care delivery, can ‘prevent the death of medical ethics.’     

Consequences of violating the assumption of independence in the process dissociation procedure: A word fragment completion study

In three experiments that used levels of processing and study time manipulations as independent variables in a word fragment completion task, the validity of the assumption of independence between recollection and automatic influences of memory was assessed. This assumption underlies the use of the process dissociation procedure (Jacoby, 1991), a tool suggested for distinguishing the different contributions of recollection and automatic influences of memory. Overall, it appeared that semantic processing, as compared with physical processing at study, positively affected recollection but negatively affected automatic influences of memory in word fragment completion. This negative effect on the automatic influences was reduced when the available study time decreased. The incompatibility of these results with the assumption of independence between recollection and automatic influences of memory and their impact on the applicability of the process dissociation procedure are discussed.     

An ethical excursion through labeling the mentally retarded

Review of a representative body of research data concerning the effects of the “mentally retarded” (MR) label on parents, teachers, college students, nonretarded children, communities, and persons labeled fails to support the extravagant claim of some investigators that the labeling process has psychologically damaging effects upon the individuals labeled as well as society. Negative reactions to labels could be minimized by extensive public education and counseling. Labels should be retained as formal instruments essential to establishing the eligibility of the retarded for special assistance, and for maintenance of communication within and between disciplines, without which contemporary society could not operate. An argument for the judicious use of labels is fashioned, recommending replacement of the MR label by “AD” (adaptively deficient), in keeping with the modern view of mental retardation as a psychosocial challenge deemphasizing IQ and requiring adjustment of the whole personality to demands of a complex environment (e.g., coping skill, motivation). Parents, teachers, friends, employers, and public officials could support the AD's struggle to effectively participate in community life by promoting the perennial values of respect for human dignity, fairness, equality, autonomy, and compassion. As a result of monitoring the success of such programs in all settings, public policy administrators could formulate rational approaches to improvement of service programs in the national interest.     

Investigating Conversational Dynamics: Interactive Alignment,Interpersonal Synergy,and Collective Task Performance

This study investigates interpersonal processes underlying dialog by comparing two approaches, interactive alignment and interpersonal synergy, and assesses how they predict collective performance in a joint task. While the interactive alignment approach highlights imitative patterns between interlocutors, the synergy approach points to structural organization at the level of the interaction—such as complementary patterns straddling speech turns and interlocutors. We develop a general, quantitative method to assess lexical, prosodic, and speech/pause patterns related to the two approaches and their impact on collective performance in a corpus of task‐oriented conversations. The results show statistical presence of patterns relevant for both approaches. However, synergetic aspects of dialog provide the best statistical predictors of collective performance and adding aspects of the alignment approach does not improve the model. This suggests that structural organization at the level of the interaction plays a crucial role in task‐oriented conversations, possibly constraining and integrating processes related to alignment.
