Subjects were tested on the critical flicker frequency during a 1-week period of visual deprivation (either homogeneous illumination or darkness). Deprived subjects showed no significant differences from a confined control group. Results were discussed in relation to previous research, Schultz’s theory of “sensoristasis” and Sharpless’ revision of the “law of denervation.” 相似文献

Fixation within a modified Poggendorff display was used to assess Pressey's hypothesized construct of attentive fields. In Experiment I the results for fixating near the bottom of the display supported the predictions based on Pressey's construct; however, results from fixating near the top of the display were more easily explained by a tilt effect noted by Zajac (1957).
Experiment II and III replicated the first experiment and obtained independent measures of the tilt effect. After the tilt effect was subtracted from the Poggendorff scores, the prediction based upon the attentive field construct was supported in the top fixation condition; however, only Experiment II provided support for the prediction in the bottom fixation condition. 相似文献

In the introductory psychology laboratory at Drexel University, we employ courseware modules that transform the computer into various pieces of psychological research equipment. Students enrolled in this course use the courseware modules in a series of experiments that investigate motor learning, perception, memory, and other psychological phenomena. In choosing this form of computerization, we have encountered challenges to our methods of instruction, both in the laboratory and in the lecture hall. Opportunities, in the form of financial and programming assistance, have also resulted from our computerization efforts. 相似文献

Two sentence-comprehension time experiments replicated and extended previously reported research indicating that readers initially make a quick, heuristic assignment of fillers to gaps in temporarily ambiguous sentences such as “Who did John beg to sing?” and “Who did John beg to sing for?” The Most Recent Filler heuristic readers seemed to adopt made the former “distant filler” sentence harder to comprehend than the latter “recent filler” sentence. Readers did not in general use all available sources of information in making this assignment. In particular, they usually delayed their use of verb control information so that substituting the unambiguous-control verbs “force” or “begin” for “beg” did not eliminate the distant filler inferiority. the experiments counter some criticisms that have been made of the previously reported research. The possibility that readers delay using an interesting natural category of information was raised, and its implications for the mental grammar were considered. 相似文献

It is proposed that the human sentence parsing device assigns phrase structure to word strings in two steps. The first stage parser assigns lexical and phrasal nodes to substrings of roughly six words. The second stage parser then adds higher nodes to link these phrasal packages together into a complete phrase marker.This model of the parser is compared with ATN models, and with the two-stage models of Kimball (1973) and Fodor, Bever and Garrett (1974). Our assumption that the units which are shunted from the first stage to the second stage are defined by their length, rather than by their syntactic type, explains the effects of constituent length on perceptual complexity in center embedded sentences and in sentences of the kind that fall under Kimball's principle of Right Association. The particular division of labor between the two parsing units allows us to explain, without appeal to any ad hoc parsing strategies, why the parser makes certain ‘shortsighted’ errors even though, in general, it is able to make intelligent use of all the information that is available to it. 相似文献

Behavioral Approach System (BAS) Sensitivity and Bipolar Spectrum Disorders: A Retrospective and Concurrent Behavioral High-Risk Design 总被引:1,自引:0,他引:1

In this article, we tested the vulnerability hypothesis of the behavioral approach system (BAS) hypersensitivity model of
bipolar disorders. We examined whether self-reported BAS sensitivity predicts lifetime bipolar spectrum diagnoses as well
as symptoms and personality characteristics associated with bipolar disorder using a retrospective and concurrent behavioral
high-risk design. Participants with high (HBAS; n=28) or moderate (MBAS; n=24) BAS sensitivity were selected and given a lifetime psychiatric diagnostic interview and self-report measures of proneness
to bipolar symptoms, current symptoms, and personality characteristics relevant to bipolarity. HBAS participants were significantly
and substantially more likely to have a lifetime bipolar spectrum disorder diagnosis than were MBAS participants, but did
not differ from MBAS participants in their likelihood of a unipolar depression diagnosis. Also, the HBAS group exhibited higher
impulsivity and proneness to hypomanic symptoms than the MBAS group, and BAS-reward responsiveness predicted hypomanic personality
characteristics. Finally, high behavioral inhibition system (BIS) sensitivity was associated with proneness to and current
depressive symptoms.

E-mail is used to maintain two primary human relationships, interaction between individuals and preserving relationships with organizations. 278 participants from a medium-size university in the southwest completed two measures developed to assess the quantity of e-mail used to maintain interpersonal and organizational relationships. Analysis indicated that men (M = 5.8, SD = 2.7) and women (M = 6.6, SD = 2.5) significantly differed in frequency of e-mail used to maintain interpersonal relationships, but not in reference to organizational maintenance. 相似文献

Five experiments investigated the interpretation of quantified noun phrases in relation to discourse structure. They demonstrated, using questionnaire and on-line reading techniques, that readers in English prefer to give a quantified noun phrase in (VP-external) subject position a presuppositional interpretation, in which the noun phrase limits or restricts the interpretation of an already available set, rather than giving it a nonpresuppositional or existential interpretation, in which it introduces completely new entities into the discourse. Experiment 1 showed that readers prefer a presuppositional interpretation of three ships over the existential interpretation in Five ships appeared on the horizon. Three ships sank. Experiment 2 showed longer reading times in sentences that are disambiguated toward the existential interpretation than in sentences that permit the presuppositional interpretation. Experiment 3 suggested that the presuppositional preference is greater when the phrase three ships occurs outside the verb phrase than when it occurs inside the verb phrase. Experiment 4 showed that Korean subjects marked with a topic marker received more presuppositional interpretations than subjects marked with a nominative marker. Experiment 5 showed that German subjects in VP-external (but nontopic) position received more presuppositional interpretations than VP-internal subjects. The results suggest the syntactic position of a phrase is one determinant of its interpretation, as expected according to the mapping hypothesis of Diesing (1992).This research was supported in part by grants HD-18708 and HD-17246 to the University of Massachusetts.

The utility of the Millon Behavioral Health Inventory (MBHI) in screening for the formal diagnosis of a psychiatric disorder was investigated in a sample of 90 heart transplant candidates, a population at risk for psychiatric disturbance. Psychiatric disorders were identified in 71% of patients, the majority being adjustment disorder. Sensitivity and specificity rates of >70% were determined in discriminant function analyses, for presence or absence of a psychiatric condition. When Axis I conditions were differentiated as mild (adjustment reaction only) or severe (all other Axis I conditions, including comorbid Axis II disorders), the MBHI correctly identified every severe case as a probable psychiatric diagnosis. The rate of clinically significant elevations on certain MBHI scales and severity of Axis I psychiatric condition was also significantly associated. These findings suggest that the MBHI may have potential utility in identifying high-risk patients with diagnosable psychiatric conditions and help justify mental health consultation referrals at a time when managed care entities are vigorously rationing ancillary services with medically ill populations. 相似文献
