There appears to be a relative absence of studies that have examined the prevalence of cognitively intact individuals who reside in extended care facilities. Prevalence data were collected on 296 persons who resided in 3 extended care nursing facilities in Central Virginia. Cognitive intactness was evaluated via the Minimum Data Set Cognitive Performance Scale (CPS) and an author-generated survey (i.e., Cognitively Intact Survey [CI Survey]) of select nursing staff members at each facility. The Mini-Mental State Examination (MMSE) was utilized to examine the accuracy of the two measures in identifying cognitive intactness. Findings indicated that prevalence rates of cognitively intact residents varied as a function of the measures utilized to assess intactness. Specifically, a significantly greater proportion of the total sample of residents was judged to be cognitively intact via the CI Survey (34.12%) as compared to the CPS (26.01%). The level of interjudge agreement between the two measures was found to be moderately high (K = 0.68). When the MMSE was employed to verify individuals' levels of intactness, the percentages of residents predicted to actually be cognitively intact were somewhat lower for each measure. Specifically, based on the data obtained via the CI Survey, 22.75% of the total sample were predicted to actually be cognitively intact, whereas 17.85% of the sample were predicted to be intact based on the CPS results. Findings are discussed in light of factors that may have contributed to the differential prevalence rates of cognitively intact individuals obtained across the measures utilized in this study. Concerns regarding the utilization of the MMSE as a criterion measure of cognitive intactness in persons residing in extended care nursing facilities are provided, along with data on the living environments/roommate statuses of those residents judged to be intact via the CI Survey. Implications for the design of future extended care nursing units, as well as future research, are also included. 相似文献

Numerous studies have demonstrated impaired recall when the to-be-remembered information is accompanied or followed by irrelevant information. However, no current theory of immediate memory explains all three common methods of manipulating irrelevant information: requiring concurrent articulation, presenting irrelevant speech, and adding a stimulus suffix. Five experiments combined these manipulations to determine how they interact and which theoretical framework most accurately and completely accounts for the data. In Experiments 1 and 2, a list of auditory items was followed by an irrelevant speech sound (the suffix) while subjects engaged in articulatory suppression. Although articulatory suppression reduced overall recall compared to a control condition, comparable suffix effects were seen in both conditions. Experiments 3 and 4 found reliable suffix effects when list presentation was accompanied by irrelevant speech. Experiment 5 found a suffix effect even when the irrelevant speech was composed of a set of different items. Implications for working memory, pre-categorical acoustic store, the changing-state hypothesis, and the feature model are discussed. 相似文献

The attribution of control to God may have particularly interesting psychological properties. Theodicy refers to the perception
of God controlling history—even the minutiae of daily events. The current study examines the psychometric properties of a
new instrument, the Theodicy Scale. Results support the reliability of the brief scale when administered to college students,
and some evidence is provided suggesting construct validation. Theodicy appears to represent a unitary construct and scores
vary independent of social desirability bias. The absence of a relationship between Theodicy scores and simulated medical
advice raises questions to be addressed in future research. 相似文献

The present experiment investigated the hypothesis that age-related declines in cognitive functioning are partly due to a decrease in peripheral sensory functioning. In particular, it was suggested that some of the decline in serial recall for verbal material might be due to even small amounts of degradation due to noise or hearing loss. Older and younger individuals identified and recalled nonsense syllables in order at a number of different speech-to-noise ratios. Performance on the identification task was significantly correlated with performance on a subsequent serial recall task. However, this was restricted to the case in which the stimuli were presented in a substantial amount of noise. These data show that even small changes in sensory processing can lead to real and measurable declines in cognitive functioning as measured by a serial recall task. 相似文献

The combined impact of infant colic and maternal depression on infant, parent, and family difficulties was examined. The sample included 93 consecutive patients seen at an outpatient Colic Clinic. Most mothers had private insurance and completed high school. Infants were approximately 2 months of age. Questionnaires completed by the mother prior to treatment onset were used to measure depressive symptoms in the mothers, infant cry, sleep and temperament, characteristics, parenting stress, maternal self‐esteem, social support, and family function. Moderate to severe depressive symptoms were reported by 45.2% of the mothers. More severe depressive symptoms in the mothers were related to fussy/difficult infant temperament, more parenting stress, lower parental self‐esteem, and more family‐functioning problems. Pediatric health care providers need to be aware that the combined effects of colic and maternal depression can be problematic for the family. ©2005 Michigan Association for Infant Mental Health. 相似文献

Researchers argue that the effectiveness of cognitive versus affective persuasive appeals depends in part on whether the appeal is congruent or incongruent with a primarily cognitive or affective attitude base. However, considerable research suggests that these persuasion effects may hold only for predominantly affective attitudes and not cognitive attitudes. Indeed, results of Experiment 1 show that the relative effectiveness of congruent relative to incongruent persuasion appeals holds for brands with predominantly affective associations, but not those with predominantly cognitive associations. Experiment 2 explores one reason for this anomalous finding: Cognitive attitudes may be relatively impervious to persuasive appeals because the probability of targeting the specific attribute on which the cognitive attitude is based is smaller. The results are supportive, showing that significant persuasion effects are found when the specific beliefs on which cognitive attitudes are based are taken into account. However, these effects only occur under conditions of low cognitive load and not high cognitive load where resources for the cognitive processing of the appeals are limited. We discuss the implications of the research for the role of attitude structure in understanding persuasion effects and the interplay of affective and cognitive elements in persuasion processes. 相似文献

Recent work in the learned helplessness paradigm suggests that neuronal sensitization and fatigue processes are critical to producing the behavioral impairment that follows prolonged exposure to an unsignaled inescapable stressor such as a series of electric tail shocks. Here we discuss how an interaction between serotonin (5-HT) and corticosterone (CORT) sensitizes GABA neurons early in the pretreatment session with inescapable shock. We propose that this process eventually depletes GABA, thus removing an important form of inhibition on excitatory glutamate transmission in the amygdala, hippocampus, and frontal cortex. When rats are re-exposed to shock during shuttle-escape testing 24 hrs later, the loss of inhibition (as well as other excitatory effects) results in unregulated excitation of glutamate neurons. This state of neuronal over-excitation rapidly compromises metabolic homeostasis. Metabolic fatigue results in compensatory inhibition by the nucleoside adenosine, which regulates neuronal excitation with respect to energy availability. The exceptionally potent form of inhibition associated with adenosine receptor activation yields important neuroprotective benefits under conditions of metabolic failure, but also precludes the processing of information in fatigued neurons. The substrates of adaptive behavior are removed; performance deficits ensue. 相似文献

This study utilized performance-based and self-report measures to examine differences in executive functions in college students with and without histories of childhood maltreatment. On the performance-based measures of executive function, all scores fell within the normal range for age. However, participants in the childhood maltreatment group reported more problems with metacognition than those without history of maltreatment. Severity of childhood maltreatment was associated with poorer cognitive inhibition/switching and phonetic fluency. Although significant group differences were found on a laboratory-based task of executive function, performance across the other tasks was generally similar. However, those with a history of maltreatment reported more problems with metacognition, suggesting a potential avenue for brief interventions focused on improving metacognitive skills important for success in the college environment. Implications and suggestions for future research are discussed. 相似文献
