Word length and articulatory suppression affect short-term and long-term recall tasks

In six experiments, subjects were required to recall (either serially or freely) lists of short and long words either immediately or after a study-test filled delay ranging from 30 to 60 sec. In three of these experiments, we investigated the effect that articulatory suppression had in modulating the word length effect in both immediate and delayed free recall. The results suggested that the effects of word length and articulatory suppression were comparable in the immediate and delayed recall tasks. The theoretical relevance of these findings is discussed.     

Baby talk from the perspective of discourse production: Linguistic choices and context coding by different speakers

Twenty men and 20 women with children under 3 years of age, and 20 men and 20 women without children were asked to select the most suitable utterance for a series of drawings representing different contexts of mother/father-infant interaction. Data were analyzed in three sections related to different hypotheses: In Phase 1, informational content and syntactic construction of sentences were selected in strict relationship with context by all speakers (closeness to context rule); in Phase 2, different speech acts were selected by different speakers within the same context (analysis of illocutionary force and canonicality); in Phase 3, the same contexts were linked to different interactional dimensions for the four groups, which formed different representations of the same interactional scene. Results are discussed in an attempt to integrate specific rules of adult-infant interaction and more general aspects of discourse production.     

Abortion in adolescence

Sexual attitudes and behavior of adolescent females have been the topic of much interest over the past decade. Feelings about contraception, conception, and abortion have been described in relation to the adolescents' beliefs about the possibility of becoming pregnant, who will or will not "protect" them, and the influence of significant others on their decision making. This study explores differences in 35 women who had abortions during their teenage years with 36 women whose abortions occurred after the age of twenty. A demographic questionnaire, the Millon Clinical Multiaxial Inventory, and the Beck Depression Inventory were completed by women who were members of a patient-led support group. Premorbid psychiatric histories, the decision-making process itself, and distressing symptoms postabortion are reported. Specific differences in perceptions of coercion, preabortion suicidal ideation, and nightmares post-abortion were found in the adolescent group. Antisocial and paranoid personality disorders as well as drug abuse and psychotic delusions were found to be significantly higher in the group who aborted as teenagers. Hypotheses regarding the influences of adolescent development on mother/child relationships, power struggles, and the use of fantasy as a coping device are explored.     

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.     

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.     

Cross-modal and intra-modal binding between identity and location in spatial working memory: The identity of objects does not help recalling their locations

In this study we tested incidental feature-to-location binding in a spatial task, both in unimodal and cross-modal conditions. In Experiment 1 we administered a computerised version of the Corsi Block-Tapping Task (CBTT) in three different conditions: the first one analogous to the original CBTT test; the second one in which locations were associated with unfamiliar images; the third one in which locations were associated with non-verbal sounds. Results showed no effect on performance by the addition of identity information. In Experiment 2, locations on the screen were associated with pitched sounds in two different conditions: one in which different pitches were randomly associated with locations and the other in which pitches were assigned to match the vertical position of the CBTT squares congruently with their frequencies. In Experiment 2 we found marginal evidence of a pitch facilitation effect in the spatial memory task. We ran a third experiment to test the same conditions of Experiment 2 with a within-subject design. Results of Experiment 3 did not confirm the pitch–location facilitation effect. We concluded that the identity of objects does not affect recalling their locations. We discuss our results within the framework of the debate about the mechanisms of “what” and “where” feature binding in working memory.     

Thalamic Amnesia Following Venous Infarction: Evidence from a Single Case Study

The present paper describes the case of a right-handed Italian–English bilingual male patient suffering from amnesia following a bilateral thalamic lesion due to venous infarction. Within a few months from the onset, the lesion gradually shrank and was finally confined to the left thalamus only, in particular to the antero-medial portion and the pulvinar. The mammillary bodies and the cortical areas of both hemispheres were spared. After the regression of a series of generalized cognitive deficits implying slow psychic activity, confusion, and spatial and temporal disorientation, the patient presented a persistent amnesic syndrome with mild language disorders, both in Italian and in English. Major disorders of memory included a dissociation between verbal memory, which was severely impaired, and spatial memory, which was largely preserved.     

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.’     

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.
