Analyses examined both positive emotion (PE) at baseline and change in PE from baseline to follow up as predictors of change in functional status (FS). Initial models examined baseline PE, and change in PE, as predictors of change in FS adjusted for baseline PE, negative emotion (NE), FS, and age and gender. Final models included additional adjustments for frequency of social contact, marital status, body mass index, smoking status, drinking behavior, and comorbidity at baseline. Baseline PE was a predictor of change in FS, adjusted for NE, age, and gender (p?=?0.033). Additional covariates reduced the effect of baseline PE as a predictor of change in FS (p?=?0.115). Change in PE was a significant predictor of change in FS – increases in ratings of PE over time were associated with less decline in FS (p?=?0.001). The association for change in PE remained significant in the fully adjusted model (p?=?0.004). Results replicate our prior findings.  相似文献

In practice, a single test is used to quantify an individual's proprioception. Previous studies have not found a correlation between joint position sense (JPS) and force sense (FS), which are submodalities of proprioception. The purpose of the present study is to determine if root mean square (RMS) error in JPS and FS are related at the shoulder, controlling for external load and elevation angle. Active shoulder angle and force reproduction protocols were performed. No correlation was found between JPS and FS (r = –.019, p = .941) nor were any individual angle and load combinations significant. The main effect for angle in JPS was significant (p < .001). Follow-up contrast demonstrated a significant (p < .001) decrease in RMS error with increased elevation. A significant load by angle interaction was found for FS (p = .014). Follow-up simple effects tests by angle demonstrated RMS error decreased with load at 50° and 70° but not at 90°. By load, RMS error only decreased for 120% between 50° and 90°. JPS and FS demonstrate different behavior with load and angle. This differing behavior is more likely responsible for the lack of correlation than angle and load differences in JPS and FS protocols.  相似文献

Bilinguals obtain larger digit spans in the language in which speech rate is fastest. This effect is generally interpreted as support for a central tenet of working memory theory, which proposes subvocal rehearsal rate as an influential determinant of memory span. Variation in the method of speech rate estimation, however, has been high, making comparison between studies difficult. In the present study, we compared the predictive power of three estimates of speech rate in relation to auditory digit span for two distinct bilingual types across nine school grades (1–9). One type spoke Swedish in the home and school (SS), the other spoke Finnish in the home and Swedish at school (FS). The results showed SS consistently obtained faster speech rates in Swedish, whereas FS obtained shorter articulation and numeral reading times in Swedish, as did grades 1–3 on a digit word reading task. However, FS grades 4–9 obtained equivalent digit word reading times between the languages. SS obtained a larger digit span in Swedish than Finnish, whereas FS obtained an equivalent digit span between the languages. Thus the results indicated that memory span was mediated by factors other than phonological loop functioning, as articulation time did not predict memory span performance for FS. The finding that FS obtained lower digit spans in Swedish relative to SS suggested that the former were disadvantaged in the processing of digits compared to native speakers of the language of schooling.  相似文献

In a recent trial for generalized anxiety disorder (GAD), cognitive-behavioral therapy (CBT) integrated with motivational interviewing (MI) promoted more long-term worry reduction than CBT alone (Westra, Constantino, & Antony, 2016). A follow-up analysis found that CBT vs. MI-CBT clients evidenced greater increases in friendly submissiveness (FS) across treatment, which in turn promoted lower long-term worry (Constantino, Romano, Coyne, Westra, & Antony, 2018). It was unsurprising that traditional directive CBT promoted more FS than when person-centered MI was integrated; however, given that problematic low agency characterizes GAD, that greater FS promoted better outcome was unexpected. To further unpack this unexpected result, we tested the following moderated mediation hypothesis: for clients with more vs. less problematic low agency at baseline, CBT would still promote more in-session FS than MI-CBT, but this increase would in turn predict increased worry over follow-up. Clients receiving CBT (n = 43) or MI-CBT (n = 42) rated their interpersonal problems at baseline and their worry after treatment and across 12-month follow-up. Therapists rated clients’ in-session FS multiple times. As predicted, multilevel modeling revealed that for clients with more problematic low agency, CBT vs. MI-CBT facilitated greater FS, which in turn related to increased worry across follow-up. For clients with more problematic high agency, CBT’s facilitation of greater FS related to reduced worry across follow-up. A baseline interpersonal problem characteristic of GAD may have implications for treatment matching and for appreciating different pathways to long-term improvement, or deterioration, for different GAD subgroups.  相似文献

Sixty-four subjects, divided into four groups of 16 according to sex and familial sinistrality (FS), were given a lateralized Object-Naming Latency Task (ONLT) and a Lexical Decision Latency Task (LDLT). Both tasks showed RVF superiorities. On the ONLT a sex × FS × visual field interaction was obtained, with FS− females and FS+ males showing comparably smaller RVF superiorities than FS+ females and FS− males. On the LDLT an FS by Stimulus Type (word-nonword) interaction was found, FS− subjects being more RVF superior for nonword trials and FS+ subjects more RVF superior for word trials. If one compared only FS− males and females, as some studies have done, greater RVF superiorities obtained for males than females on both the ONLT and word trials of the LDLT. However, FS+ subjects showed the opposite pattern. The data support neither the simple model of FS nor sex influence on language laterality. Data aslso suggest that a history of maternal versus paternal left-handedness may affect lateralization differently in the sexes.  相似文献

The finding of fractal scaling (FS) in behavioral sequences has raised a debate on whether FS is a pervasive property of the cognitive system or is the result of specific processes. Inferences about the origins of properties in time sequences are causal. That is, as opposed to correlational inferences reflecting instantaneous symmetrical relations, causal inferences concern asymmetric relations lagged in time. Here, I integrate Granger-causality with inferences about FS. Four simulations illustrate that causal analyses can isolate distinct FS sources, whereas correlational techniques cannot. I then analyze three simultaneous sequences of responses from a database of word-naming trials. I find that two, or perhaps three, distinct sources account for the presence of FS in these sequences, but FS is not a general property of the system. This suggests that FS arises due to the properties of a limited number of identifiable psychological and/or neural processes. Finally, I reanalyze a previously published dataset of acoustic frequency spectra using the new tools. The causality/criticality combination introduced here offers a new important perspective in the study of cognition.  相似文献

This study presents the results of three experiments in which the Family Size (FS) effect is explored. The first experiment is carried out with no prime on simple words. The second and third experiments are carried out with morphological priming on complex words. In the first experiment a facilitatory effect of FS is observed: high FS targets produced faster responses than low FS targets. However, an inhibitory effect of Stem-FS is observed in the second experiment: low Stem-FS targets produced faster responses than high Stem-FS targets. In the third experiment a facilitatory effect is observed when the Affix-FS is manipulated: high Affix-FS targets produced faster responses than low Affix-FS targets. Overall data confirms that the effect of FS plays an important role in lexical access in Spanish. The results also show that the effect of FS is modulated by the lexical nature of the prime (lexical or sublexical) and by the number of candidates activated. Finally, it is suggested that the nonwords employed were decisive in obtaining the results mentioned.  相似文献

We compared right-handed familial dextral (FS-) and familial sinistral (FS+) participants who were aged either 10-13 years (children) or 18-23 years (adults). In word probe and associative probe tasks, FS+ adults responded faster than all other groups and FS+ children responded more slowly than all other groups. In the word probe task, only the FS- adults showed a significant effect of the serial position of the target word. We interpret these differences to support an analysis-by-synthesis model of comprehension in which individuals who differ in familial handedness and age emphasize different linguistic representations during comprehension. In general, FS+ individuals focus on words and meaning, while FS- individuals focus on syntactic representations. In FS+ individuals, age-related experiences with language produce a shift in responding from compositional meaning to words and their associations. In FS- individuals, age-related experiences with language produce a shift toward responding based more on detailed syntactic representations, including the serial order of words and possibly the structural roles of clauses.  相似文献

Three experiments explored the impact of different reinforcer rates for alternative behavior (DRA) on the suppression and post‐DRA relapse of target behavior, and the persistence of alternative behavior. All experiments arranged baseline, intervention with extinction of target behavior concurrently with DRA, and post‐treatment tests of resurgence or reinstatement, in two‐ or three‐component multiple schedules. Experiment 1, with pigeons, arranged high or low baseline reinforcer rates; both rich and lean DRA schedules reduced target behavior to low levels. When DRA was discontinued, the magnitude of relapse depended on both baseline reinforcer rate and the rate of DRA. Experiment 2, with children exhibiting problem behaviors, arranged an intermediate baseline reinforcer rate and rich or lean signaled DRA. During treatment, both rich and lean DRA rapidly reduced problem behavior to low levels, but post‐treatment relapse was generally greater in the DRA‐rich than the DRA‐lean component. Experiment 3, with pigeons, repeated the low‐baseline condition of Experiment 1 with signaled DRA as in Experiment 2. Target behavior decreased to intermediate levels in both DRA‐rich and DRA‐lean components. Relapse, when it occurred, was directly related to DRA reinforcer rate as in Experiment 2. The post‐treatment persistence of alternative behavior was greater in the DRA‐rich component in Experiment 1, whereas it was the same or greater in the signaled‐DRA‐lean component in Experiments 2 and 3. Thus, infrequent signaled DRA may be optimal for effective clinical treatment.  相似文献

Processing asymmetries for tactile-spatial and auditory-verbal processing were investigated in two studies using the S. F. Witelson (1974, Cortex, 10, 3–17) dichaptic procedure. Experiment 1 used eight right-handed males in a free recall procedure. More shapes were correctly detected by the left hand but only with a right hand response. In Experiment 2, right and left handers with no Familial Sinistrality (FS) were compared with left handers with various types of FS, looking at pre- and postcued order of report and precuing the response hand. No group showed hand asymmetry with pre- or postcuing for either responding hand. Right handers showed no difference with order of report; however, left handers made fewer correct detections for items to be reported second. There were differences between the Parental FS and the Sibling FS groups both on the dichotic listening and the haptic tasks.  相似文献

Concepts from behavioral momentum theory, along with some empirical findings, suggest that the rate of baseline reinforcement may contribute to the relapse of severe destructive behavior. With seven children who engaged in destructive behavior, we tested this hypothesis in the context of functional communication training by comparing the effects of different baseline reinforcement rates on resurgence during a treatment challenge (i.e., extinction). We observed convincing resurgence of destructive behavior in four of seven participants, and we observed more resurgence in the condition associated with high‐rate baseline reinforcement (i.e., variable‐interval 2 s in Experiment 1 or fixed‐ratio 1 in Experiment 2) compared to a low‐rate baseline reinforcement condition. We discuss the implications of these results relative to schedules of reinforcement in the treatment of destructive behavior and strategies to mitigate resurgence in clinical settings.  相似文献

The importance of previous suicidal behavior for the treatment of alcoholics was analyzed in a long-term outpatient treatment study. In a series of 72 patients, 21 patients, (29%), 17 men and 4 women, had previously made at least one suicide attempt or had seriously threatened to kill themselves (3 cases). In comparison with the other alcoholics, those with previous suicidal behavior had a similar attrition rate, they were not more troublesome in treatment, and they had the same rate of favorable outcome during the third year after start of treatment. They differed from the other alcoholics in having a more severe abuse and a less favorable outcome during the initial part of the treatment. In conclusion, our results support the possibility of a long-term outpatient treatment strategy in alcoholics with previous suicide attempts.  相似文献

We evaluated a differential-reinforcement-based treatment package for the reduction of problem behavior during instructional situations. Differential reinforcement of alternative behavior (DRA; compliance) was implemented across two conditions. During one condition, instructions were presented approximately once every other minute. This condition was considered the terminal goal for treatment. During the second condition, the rate of instructions was gradually increased (beginning at zero and ending when instruction rate was similar to the first condition). Results indicated that DRA with instructional fading resulted in less problem behavior than DRA without instructional fading. These results are similar to previous studies regarding the utility of instructional fading.  相似文献

Generalization across three stimulus parameters was examined for 5 individuals whose self-injurious behavior was maintained by escape from task demands. Prior to treatment, three stimulus parameters (therapist, setting, and demands) were systematically varied across baseline sessions. These variables were held constant during treatment, which consisted of escape extinction. When treatment was completed, three novel stimulus parameters were probed. If the rate of self-injury was high during this probe, treatment was reimplemented with one new stimulus parameter (the other two were the same as in the original treatment condition). Following this second treatment, another probe with three novel stimuli was conducted. If the rate of self-injury was again high, treatment was implemented again while a second stimulus parameter was changed. This sequence continued until generalization was observed across the three parameters. Results showed idiosyncratic differences in generalization. The behavior of 2 subjects showed complete generalization during the first novel probe. A 3rd subject's behavior showed generalization following treatment across two stimulus parameters (setting and therapist). The behavior of the 2 remaining subjects showed a complete lack of generalization across the three parameters; both subjects required training for novelty by randomly varying the stimulus parameters for a substantial number of sessions.  相似文献

Female undergraduates (N = 240) assessed for fear of success (FS) and fear of failure (FF) competed against a male, female, or no opponent (norms) on an alpha-numeric substitution task. After completing one set of trials, subjects arbitrarily received success or failure feedback, then performed again. While there were no significant effects when subject's FS classification was based on total scores from the entire set of four cues used, performance effects were found for Horner's original cue: FS-absent females performed better against a male than a female opponent, whereas the reverse was true for the FS-present subjects. Two of the other FS cues interacted with FF: at low levels of FF, FS-absent subjects performed better than FS-present subjects; for high levels of FF, there were no differences between FS groups. A number of postperformance affect ratings were consistent with theoretical expectations that FS-present females would experience more negative effect over success in achievement contexts than would FS-absent females.  相似文献

The present study compared the physical and mental health and the health care use of spouses of patients with fibromyalgia syndrome (FS group; n = 135) with that of spouses of healthy individuals (n = 153). FS group participants reported lower health and affective states and scored higher on depression, loneliness, and subjective stress than comparison group participants (p < .017). Husbands in the FS group who reported more illness impact and whose wives reported worse sleep quality and less self-efficacy had more psychological difficulties. No differences were found in health care costs between groups. These findings suggest that chronic illness in a partner may negatively affect an individual's physical and mental health.  相似文献

I investigated the differential effects of self-monitoring of attentional behavior and self-monitoring of productivity on on-task behavior and academic response rate. Subjects were four learning disabled children with significant attentional problems. Results indicated relatively equivalent increases in on-task behavior over baseline during all treatment phases. Academic response rate also improved under both interventions, with self-monitoring of productivity showing a superior effect for one subject, an equivalent effect for one subject, and less dear results for two subjects.  相似文献

An adjusting fixed-ratio schedule of praise and immediate correctness feedback produced increases in a seventh-grade student's arithemic response rate. Percentage of time spent in attending behavior also increased collaterally. Removal of the treatment led to decreases in both arithmetic response rate and collateral attending behavior. Reinstatements of the procedure again produced increases in both types of behavior. It was suggested that the present procedure of directly modifying arithmetic response rate requires less time and effort than working indirectly through modifying attending behavior.  相似文献

A subtheory of the theory of self-referential truth known as FS is shown to be weak as a theory of truth but equivalent to full FS in its proof-theoretic strength.  相似文献

Geschwind and Galaburda (1987) proposed that immune disorder (ID) susceptibility, along with left handedness and familial sinistrality (FS), is a "marker" for anomalous dominance. The theory predicts lesser left lateralization for language processes, lessened left hemisphere abilities, and enhanced right hemisphere abilities. We assessed language laterality (dichotic consonant vowel task) and performances on spatial and verbal tasks. Subjects were 128 college students. The factors of handedness, sex, FS, and immune disorder history (negative or positive) were perfectly counterbalanced. Left-handers were significantly less lateralized for language and scored lower than right-handers on the spatial tasks. Females scored lower on mental rotation than males, but performed comparably to males on the spatial relations task. The only effect of ID was by way of interaction with FS on both spatial tasks--subjects who were either negative or positive on both FS and ID status factors scored significantly higher than subjects negative for one but positive for the other factor. A speculative explanatory model for this interaction was proposed. The model incorporates the notion that FS and ID factors are comparably correlated, but in opposite directions, with hormonal factors implicated by other research as relevant for spatial ability differences. Finally, no support for the "anomalous dominance" hypothesis predictions was found.  相似文献
