Protective buffering and emotional desynchrony among spousal caregivers of cancer patients.

OBJECTIVE: To examine protective buffering and emotional desynchrony among spousal caregivers of cancer survivors. DESIGN: Repeated measures; 42 caregivers engaged in 2 videotaped, oral emotional expression exercises: 1 in the presence of their patient and 1 in the absence of their patient. MAIN OUTCOME MEASURES: Felt emotion (self-report) and expressed emotion (lexical expression or words uttered and coder-derived facial expression). Other measures assessed mental and physical health, dyadic satisfaction, and dispositional emotional inhibition. RESULTS: Protective buffering differed by communicative channel (lexical vs. facial). Caregivers' facial expressions were more positive when the patient was present versus absent. In contrast, the valence of caregivers' words did not differ per patient presence. Facial protective buffering was unrelated to health and dyadic outcomes. Lexical protective buffering was inversely related to both caregiver and patient marital satisfaction. Dispositional emotional inhibition was inversely related to caregiver mental health and marital satisfaction. Desynchrony occurred when the patient was present but was counter to prediction; felt emotion was more positive than expressed emotion. CONCLUSION: Results provide behavioral evidence of facial protective buffering. To the extent that lexical buffering occurs, it poses a dyadic risk, and chronic inhibition poses both psychological and dyadic risks. Future research is needed to refine the operational definition of desynchrony and to examine the biopsychosocial sequelae of buffering.     

群体认同、自尊和心理疾病污名的关系

通过对620位在校大学生进行问卷施测,探讨大学生群体认同、自尊和心理疾病污名之间的内在关系,并使用LISREL 8.70建构了彼此之间的关系模型,进行了中介效应分析.结果发现:(1)群体认同显著地负向预测自我污名,且通过自尊和公众污名这两个中介变量影响自我污名;(2)自尊显著负向预测自我污名,公众污名显著正向预测自我污名.结论:三个变量之间相关非常显著;所建构的模型具有较高的拟合度.     

Contextual cueing under working memory load: Selective interference of visuospatial load with expression of learning

In a series of experiments, we investigated the dependence of contextual cueing on working memory resources. A visual search task with 50 % repeated displays was run in order to elicit the implicit learning of contextual cues. The search task was combined with a concurrent visual working memory task either during an initial learning phase or a later test phase. The visual working memory load was either spatial or nonspatial. Articulatory suppression was used to prevent verbalization. We found that nonspatial working memory load had no effect, independent of presentation in the learning or test phase. In contrast, visuospatial load diminished search facilitation in the test phase, but not during learning. We concluded that visuospatial working memory resources are needed for the expression of previously learned spatial contexts, whereas the learning of contextual cues does not depend on visuospatial working memory.     

Text processing and feedback: what have we learned?

In studies on the effects of feedback on text comprehension, it was determined that text content interacts differentially with the feedback provided. Specifically, the types of memorial representations sought must be considered in terms of type of text, feedback timing, frequency, and modality.     

When practice makes imperfect: debilitating effects of overlearning

It was hypothesized that as overlearning leads to "mindlessness," the individual components of a task become relatively inaccessible to consciousness and therefore unavailable to serve as evidence of task competence. This may lead to a decrement in performance if circumstances, for example, a label connoting relative inferiority, lead one to question one's ability. This was tested in the first experiment by varying practice on a task (no practice, moderate practice, and overpractice) by label assigned to subjects (no label, assistant, boss). As predicted, performance decrements resulted for the no practice and overpracticed subjects who were assigned the inferior status label but not for the moderate practice subjects for whom the task components were still salient. In a second experiment it was found that the debilitation could be prevented for an overlearned task by making components of the task salient. Implications for the vulnerability of experts to these performance debilitations are explored.     

Long-term effects of a control-relevant intervention with the institutionalized aged

Elderly nursing home residents who were tested as part of an intervention designed to increase feelings of choice and personal responsibility over daily events were reevaluated 18 month later. Nurses' ratings and health and mortality indicators suggest that the experimental treatment and /or the processes that it set in motion had sustained beneficial effects.     

Pregnancy: A social stigma?

Experimental evidence is presented which explores the social stimulus value of pregnancy. It was found that, for men especially, the pregnant woman elicits avoidance and staring and that these responses occur primarily because pregnancy is a novel visual stimulus. For women, avoidance seems to be tied less to the stimulus aspects of the pregnant woman than to role expectations about her behavior. The pregnant woman is expected to be passive, but is simultaneously rejected for being so. It is argued that this constellation of responses may produce discomfort and withdrawal in the pregnant woman herself, since avoidance and staring are easily interpreted as negative reactions. How these reactions fit into the cultural response to pregnancy is discussed.     

Pre- and postlexical loci of contextual effects on word recognition

The context in which a word occurs could influence either the actual decoding of the word or a postrecognition judgment of the relatedness of word and context. In this research, we investigated the loci of contextual effects that occur in lexical priming, when prime and target words are related along different dimensions. Both lexical decision and naming tasks were used because previous research had suggested that they are differentially sensitive to postlexical processing. Semantic and associative priming occurred with both tasks. Other facilitative contextual effects, due to syntactic relations between words, backward associations, or changes in the proportion of related items, occurred only with the lexical decision task. The results indicate that only associative and semantic priming facilitate the decoding of a target; the other effects are postlexical. The results are related to the different demands of the naming and lexical decision tasks, and to current models of word recognition.
