Using data which reflects upon the genetic makeup of patients, Cadoret, Woolson and Winokur (1977) test two theories regarding the genetic makeup of patients suffering from unipolar affective disorder. This hypothesis test is a good example of a problem in order restricted inference. Using some recently developed techniques in order restricted inference we analyze these data and compare the analyses.This research was sponsored by the Office of Naval Research under contract N00014-80-C-0321. 相似文献

A variation of Kalat and Rozin's two-presentation paradigm was used to test the hypothesis that the first, as opposed to the second, presentation of a flavor conditioned stimulus (CS) constitutes the functional CS in two-presentation experiments involving moderate interflavor intervals (IFIs), and results in flavor aversions that are a function of the primary, as opposed to the secondary, conditioned stimulus-unconditioned stimulus (CS-US) interval. Contrary to the hypothesis, it was shown in Experiment 1 that holding the primary CS-US interval constant at 4 hr for each of three groups, while decreasing the secondary CS-US interval (i.e., the interval between the second flavor presentation and the illness) from 3.75 hr to 2.5 hr to .5 hr, resulted in the flavor aversion increasing as the secondary CS-US interval decreased. However, the aversion acquired by the group with a 0.5 hr secondary CS-US interval was also found to be significantly weaker than that acquired by a single-presentation 0.5 hr control group. In Experiment 2 it was demonstrated that animals exposed to novel exteroceptive stimulation (NES) immediately prior to a second flavor presentation that preceded the US by 0.5 hr acquired an aversion as strong as that acquired by a 0.5-hr control group. In Experiment 3 it was demonstrated that, in the absence of a second flavor presentation, animals exposed to novel exteroceptive stimulation 0.5 hr prior to the US acquired a weaker flavor aversion than did animals not exposed to novel exteroceptive stimulation during the 4-hr flavor CS-illness US interval. The contrasting effects of novel exteroceptive stimulation observed in Experiments 2 and 3 were replicated in Experiment 4. The results suggest, consistent with the trace-decay hypothesis and Wagner's (1976) general model of stimulus processing, that exposure to novel exteroceptive stimulation disrupts continued processing of the short-term memory (STM) trace of the initial presentation of a flavor CS, and hence minimizes stimulus preexposure effects attributable to the priming of STM. 相似文献

This article highlights the need for a clearer conceptual appreciation of the relationships among and between predictors and criteria, and for a better understanding of measurement issues in selection. A process model of selection is outlined that includes recent research on the changing relationships of ability to performance at different stages of skill acquisition, the interaction between type of task and validity, the role of motivational constructs in the measurement and validation process, and the reciprocally interacting influences of work experience and individual characteristics. Comment is offered on issues such as general versus specific abilities, the ‘big five’in personality, aptitude by treatment or training interactions and maximal versus typical performance. Measurement issues are discussed throughout, but particularly in relation to the assessment process. 相似文献

Using anatomical dolls, the play behaviors of nine sexually abused preschool children (five males, four females), ranging in age from 3 to 5 years, were compared with nine preschool children for whom there was no suspicion of sexual abuse and who were matched on the basis of age, gender, race, family status, and socioeconomic status. There was no significant difference between the two groups on explicit sexual behavior (vaginal, oral, and anal intercourse with thrusting motions between the dolls or between the child and the dolls and masturbation by the child). The groups were significantly [t(8)=2.19, p <.05; Wilcoxon W=6, p <.05) different when behaviors with suspicious sexual implication were combined with explicit sexual behaviors. There were no differences between the groups on measures of nonsexual behavior. The occurrence of the suspicious sexual behaviors is discussed and reviews of previous doll research and physical evidence of child sexual abuse are provided.This project was supported in part by a grant from The Graduate College of Western Michigan University, Kalamazoo, Michigan. 相似文献

The relationship between activity counts from the large-scale integrated sensor (LSI), placed at the hip and ankle, and heart rate-estimated energy expenditure was examined in three nonobese males during three conditions: normal morning activities, a 1-mi walk, and a 2-mi walk. Results showed that estimated caloric expenditure was related to activity counts for both monitoring placements, with correlations between counts and energy expenditure exceedingr=.90. These results show that energy expenditure in the activities sampled can be reliably estimated using activity monitors.This research was supported in part by a grant provided by The John D. and Catherine T.

In this paper we consider the effect of imposing memory restrictions on the accumulator and random-walk models of choice behavior outlined by Audley (Psychological Review, 1960, 67, 1–15). Specifically, it is assumed that subjects apply criteria to the numbers of impulses received, and that if the criteria are not satisfied by the time w impulses have been received, then thereafter the criteria are only applied to w impulses, which could, for example, be the last w impulses received. Exact and approximate mathematical approaches and simulation techniques are presented in detail. The results obtained demonstrate that both the restricted accumulator and the restricted random-walk models can make qualitative predictions in line with much recent data. 相似文献

When people are asked moderately difficult questions, they often avert their gazes. We report five experiments in which we documented this phenomenon. They demonstrate that (1) the frequency of gaze aversion is related to the difficulty of cognitive processing, (2) this behavior cannot be due solely to demand characteristics or embarrassment, and (3) the behavior is functional: Averting the gaze improves performance. We speculate that averting the gaze helps people to disengage from environmental stimulation and thereby enhances the efficiency of cognitive processing directed by nonenvironmental stimulation. 相似文献

Two experiments are reported in which expert and novice gymnasts were required to walk across a balance beam as quickly as possible in various vision conditions. In Experiment 1, experts walked faster than novices in all vision conditions, showing the greatest superiority when vision was completely eliminated. Novices were more dependent on vision and were able to maintain their performance as long as a visual sample was available every 250 ms (i.e: 4-Hz samples).The results of Experiment 2 indicate that differences between expert and novice performers in the no-vision condition were not related to the use of a short-term visual representation of the movement environment. Our movement time findings are problematic for specificity of learning models of skill acquisition. As well, film data collected in Experiment 2 were not consistent with models that propose a transition from closed-loop to open-loop control. 相似文献

In a recent paper, Sakaki (2007) proposed that Klein and Loftus's conclusion that semantic and episodic trait self-knowledge are functionally independent (e.g., Klein, Babey, & Sherman, 1997; Klein & Loftus, 1993a; Klein, Loftus, Trafton, & Fuhrman, 1992b) was based on questionable assumptions and not supported by the available evidence. In this paper we show that Sakaki (2007) has misinterpreted our position on the independence of self-knowledge, omitted mention of large portions of the relevant research at odds with her contention, and conducted her studies with procedures we explicitly warned against due to interpretive ambiguities associated with their use. 相似文献

Major depression is the most common psychiatric disorder among cancer patients and is associated with decreased quality of life, significant deterioration in recreational and physical activities, relationship difficulties, sleep problems, more rapidly progressing cancer symptoms, and more metastasis and pain relative to nondepressed cancer patients. Although some research has explored the utility of psychological interventions with cancer patients, only one study to date has explored the potential benefits of cognitive-behavior therapy among cancer patients with well-diagnosed depression. Addressing this gap in the literature, this study represents an open clinical trial to assess the effectiveness of a brief Cognitive-Behavioral Treatment for Depression (CBTD) among depressed cancer patients in a medical care setting. Results revealed strong treatment integrity, good patient compliance, excellent patient satisfaction with the CBTD protocol, and significant pre-post treatment gains across a breadth of outcome measures assessing depression, anxiety, quality of life, and medical outcomes. These gains also were associated with strong effect sizes and generally maintained at 3-month follow-up. Behavioral activation interventions, especially when paired with cognitive techniques, may represent a practical medical care treatment that may improve psychological outcomes and quality of life among cancer patients. Study limitations and future research directions are discussed. 相似文献
