Production of narrative and procedural discourse in aphasia

The study described the abilities of a group of 10 aphasics and 10 normals to produce narrative and procedural discourse. The experimental tasks included telling stories, producing summaries, giving morals to the stories, and producing procedures. The variables examined in the investigation included features of sentential grammars, such as amount of embedding, and features of discourse grammars, such as occurrence of elements of superstructure in narrative. Additionally, raters assessed the content and clarity of the discourses. The results showed that aphasics produced well-structured narrative and procedural discourse. Aphasics' discourse errors differed only in degree, not qualitatively, from those of normals. The language of the aphasics' discourses was reduced in both complexity and amount. It was found that the aphasics had difficulties in producing summaries and giving morals for the stories when compared with the normals. Both the content and clarity of the discourses produced by the aphasics were rated lower than those produced by the normals.     

Consolidation of Memory for Odor–Reward Association: β-Adrenergic Receptor Involvement in the Late Phase

Experimentally naive rats can learn rapidly to discriminate among three odors to obtain food reinforcement. After three massed trials, they show almost errorless performance. This task has proved to be useful in studying time-dependent postacquisition intracellular processes necessary for long-term memory. The present experiments evaluated the temporal dynamics of the role of β-noradrenergic receptors in long-term consolidation. Rats were implanted with intracerebroventricular cannulae and trained in a single session to find reinforcement in a hole in a sponge impregnated with a particular odor. Injections of the β-receptor antagonist timolol were made at 5 min, 1, 2, or 5 hr after training. Memory and relearning ability were evaluated 48 hr later. Rats treated with timolol 2 hr after training showed a memory deficit at the retention test, but were able to relearn the task normally. Injections at the earlier or later time points were ineffective. The results reinforce previous observations with systemic injections that β-noradrenergic receptors are involved in the late phase of memory consolidation and suggest a critical time window during which they are necessary. The time window is compatible with the current view that long-term memory depends on late involvement of the cAMP cascade leading to new protein synthesis necessary for synaptic reorganization.     

The Relationship Between Health and Human Services and the Personal Goal-Directed Activities of Persons Living with AIDS

This study evaluates the relationship between the social climate from different services and the personal goal-directed activities of 224 individuals with AIDS. The study's results supported the main hypothesis that recipient and participatory service involvement uniquely influence personal goal-directed activities, even after considering individuals with AIDS' physical symptoms, psychological distress, income, and recruitment site. Income and involvement with participatory services were both positively related to the amount of personal goal-directed activity. Longitudinal analyses suggest that personal initiative contributes to the subsequent amount of personal goal-directed activities a person pursues. These results suggest further examination of factors contributing to the selection of different service types and of the processes underlying the relationship between participatory services and positive outcomes for clients with AIDS.     

Nonaware classical conditioning to pictorial facial stimuli in a between-groups paradigm

The present experiment investigated the effects of aware and nonaware modes of extinction in classical conditioning to facial emotional stimuli. The subjects participated in three different experimental phases. In the first (habituation) phase they were presented with a 500 ms angry face. In the second (acquisition) phase, for half of the subjects the 500 ms face was paired with an aversive noise (experimental group) while for the other half of the subjects the face and the noise presentations were separated by 6–10 s intervals (sensitization control group). In the third (extinction) phase, these two groups were further divided into two subgroups. One subgroup of both the experimental and control group had the face stimulus presented for 30 ms, and immediately masked with a neutral picture. The other two subgroups had the face presented for 500 ms with no mask. The results showed that conditioning only occurred in the experimental subgroups which was indicated by a significant difference between skin conductance responses during habituation and corresponding responses during extinction. Secondly, comparing the experimental and control groups during the extinction phase, a significant conditioning effect was observed for both the aware and nonaware masked modes of extinction for the experimental group. The results suggest that conditioned autonomic responses may be elicited in a nonaware mode.     

Stress and family health

This study investigates the difference between perceived everyday individual stress and levels of family health. Subjects completed the Family Adaptability and Cohesion Scale (FACES III), the Derogatis Stress Profile, and a personal data form. Quota sampling of 121 subjects was used to obtain 25 subjects in each of three groups: balanced, mid-range, and extreme family types. Individuals identified as members of mid-range families reported less overall stress than balanced or extreme family members. Significant differences appeared between the balanced and mid-range groups. Balanced individual family members reported slightly higher levels of stress than extreme family members.     

Rehearsing for confrontation

Social confrontation is a particular kind of communication episode which may be initiated when one actor signals another actor that his or her behavior has violated (or is violating) a rule or expectation for appropriate conduct within the relationship or situation (Newell & Stutman, 1988). This paper explores the decision, structure and process of rehearsing for confrontation. Intensive interviews with 75 actors followed by a questionnaire administered to 99 others revealed that confronters maintain two strands of confrontative goals: strategic and performance goals. Strategic goals for confronters include (a) influence, (b) catharsis, (c) relational maintenance, (d) retribution, and (e) enhanced understanding of the other. While these goals lead to different tactical outcomes, actors also hold intentions related to performance goals. Two performance goals are of central concern to some actors: (a) the desire to be argumentatively complete, and (b) the desire to maintain the position of the confronter rather than the confrontee. An analysis of the data revealed that differences in goal configurations guided both the decision to rehearse and the process of this rehearsal.     

Is health-care delivery by partially trained professionals ever morally justified?

...teaching institutions should establish policies for all aspects of care provided by residents-in-training (not just for the acquisition of informed consent to treatment) and establish mechanisms to monitor how these policies are implemented and their effect on the quality of patient care and patient satisfaction with care. Clear policy on which treatments are provided by junior residents and which treatments and aspects of care are provided by senior residents is necessary for patients and their families to have control over what happens to them in the health-care institution....Teaching institutions should regularly assess whether residents are being asked to take on more responsibilities in patient care than they are prepared to do. The reasons to do this are not solely related to protecting the patient from harm. Protecting the residents-in-training from overwhelming guilt, fear, and providing them with a more humane approach to medical education should be a minimal expectation for the training of those who will be expected to provide humane care to others....     

Multifamily interventions in the context of inherited genetic conditions: A scoping review

This scoping review sought to examine the existing literature on multifamily interventions with families dealing with inherited genetic conditions. It also seeks to identify gaps in the evidence to help guide future research and intervention development. Four databases (PubMed, Web of Sciences, Scopus and PsycInfo) were systematically searched and analysed, resulting in five publications for inclusion. The main findings evidence two main themes: characteristics of multifamily interventions, and evaluation of the intervention and impact on participants. These findings suggest that multifamily interventions can provide families with extended support beyond the care usually offered by genetic healthcare services and contribute to enhancing positive change in key aspects of adaptation and coping with an inherited genetic conditions. Multifamily discussion groups are a methodology that is particularly suitable when working with families in this context. Collaboration between genetic healthcare services and accredited systemic family therapists is required to sustain the implementation of multifamily discussion groups and their feasibility. Research on the effectiveness, feasibility and economic viability of multifamily interventions is also needed.     

Social‐cognitive mediators of the relation of environmental and emotion regulation factors to children's aggression

Tested a theoretical model in which social cognitions about aggression partially mediated the relation of environmental and emotion regulation factors to children's aggressive behavior. An ethnically diverse sample of 778 children (57% girls) in grades 4–6 from both urban and suburban schools participated. Measures included exposure to aggression (seeing/hearing about aggression, victimization), emotion regulation (impulsivity, anger control), social cognitions about aggression (self‐evaluation, self‐efficacy, retaliation approval, aggressive fantasizing, caring about consequences), and aggressive behavior. Results supported the hypothesis that social cognitions mediate the relations of exposure to aggression and anger control to aggressive behavior. Also, social cognitions about direct and indirect aggression differentially predicted the respective behaviors with which they are associated. That is, social cognitions about direct aggression were mediators of direct aggressive behavior, whereas social cognitions about indirect aggression were mediators of indirect aggressive behavior. Finally, gender moderated the relations among the variables such that for girls, retaliation approval beliefs were a strong mediator, whereas for boys, self‐evaluation was more important. Aggr.

Proof Analysis in Modal Logic

A general method for generating contraction- and cut-free sequent calculi for a large family of normal modal logics is presented. The method covers all modal logics characterized by Kripke frames determined by universal or geometric properties and it can be extended to treat also Gödel–Löb provability logic. The calculi provide direct decision methods through terminating proof search. Syntactic proofs of modal undefinability results are obtained in the form of conservativity theorems.
