Despite the strong association between alcoholism and orality in psychoanalytic theory, use of the Rorschach Inkblot Test to provide empirical support for such a link has yielded decidedly mixed results. However, Masling's Rorschach Oral-Dependency (ROD) scale has shown twice that people with alcoholism give more oral-dependent responses on the Rorschach than matched comparison groups (Bertrand & Masling, 1969; Weiss & Masling, 1970), which is supportive of classical analytic theory. In this study, we investigated alcohol groups, depression groups, and "normal" undergraduates with the ROD scale and found that the 2 clinical groups produced higher ROD scores than the undergraduates. In addition, recent studies by Duberstein and Talbot (1993) and Fowler, Hilsenroth, and Handler (1996) provide evidence for an object relations model of dependency that suggests that a balance between anaclitic dependence and complete independence, in which dependency needs are acknowledged but are not overwhelming, is most adaptive. This model of dependency was evaluated; it was found that a simple difference in group means provided a better fit with the data, although some evidence of an object relations model also was found. Finally, Rorschach and MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) levels of general defensiveness and primary process manifestations in Rorschach content were investigated to assess whether participants were responding defensively to the testing and whether there were any differences in the nature of oral-dependent responses between the clinical groups.  相似文献

The effects of regions with local linear perspective on judgments of the depth separation between two objects in a scene were investigated for scenes consisting of a ground plane, a quadrilateral region, and two poles separated in depth. The poles were either inside or outside the region. Two types of displays were used: motion-parallax dot displays, and a still photograph of a real scene on which computer-generated regions and objects were superimposed. Judged depth separations were greater for regions with greater linear perspective, both for objects inside and outside the region. In most cases, the effect of the region's shape was reduced for objects outside the region. Some systematic differences were found between the two types of displays. For example, adding a region with any shape increased judged depth in motion-parallax displays, but only high-perspective regions increased judged depth in real-scene displays. We conclude that depth information present in local regions affects perceived depth within the region, and that these effects propagate, to a lesser degree, outside the region.  相似文献

Functional decay theory proposes that decay and interference, historically viewed as competing accounts of forgetting, are instead functionally related. The theory posits that (a) when an attribute must be updated frequently in memory, its current value decays to prevent interference with later values, and (b) the decay rate adapts to the rate of memory updates. Behavioral predictions of the theory were tested in a task-switching paradigm in which memory for the current task had to be updated every few seconds, hundreds of times. Reaction times and error rates both increased gradually between updates, reflecting decay of memory for the current task. This performance decline was slower when updates were less frequent, reflecting a decrease in the decay rate following a decrease in the update rate. A candidate mechanism for controlled decay is proposed, the data are reconciled with practice effects, and implications for models of executive control are discussed.  相似文献

Reconsolidation Reconsidered   总被引:3,自引:0,他引:3  
Some of the considerations that led to a consolidation interpretation of retrograde amnesia (RA), which states that RA results from the disruption of memory processing and storage when neural activity is interrupted by a brain insult, are reviewed here. The time-dependent gradient of memory loss (i.e., new memories are more vulnerable to amnesia than old memories) that characterizes RA seemed to fit nicely with the notion of a cascade of cellular events occurring during the immediate post-acquisition period that would transform a labile representation into a more stable form (i.e., consolidate the memory). However, a variety of observations came to challenge the storage-disruption model, and among these was the finding of amnesia for old but reactivated memories. A recent study by Nader, Schafe, and LeDoux (2000) provides an important analytic extension of the work on "reconsolidation" by showing that inhibition of protein synthesis in the lateral and basal nuclei of the amygdala immediately following the reactivation of old memory will induce retrograde amnesia. We offer a retrieval-oriented conceptualization to account for the temporal gradient and the "reconsolidation" phenomena.  相似文献

Despite recent suggestions that depression can be conceptualized as a disorder of affect regulation, relatively little research has focused on affect regulation skills in depressed individuals. This paper investigated whether depressed adolescents (N = 25) differ from nondepressed adolescents (N 25) on two indices of affect regulation (i.e., duration of negative affective states and reciprocity of maternal negative affect) as well as whether these indices are related to microsocial family interactional processes. Analyses revealed that depressed teens differed from their nondepressed peers with regard to duration of negative affective states but not in their likelihood of reciprocating negative affect. Additionally, indices of adolescent affect regulation were related to family interactional processes. Duration of depressive affect was positively associated with maternal display of facilitative behavior contingent on adolescent depressive behavior. Duration of aggressive behavior was inversely related to maternal problem-solving responses to aggressive behavior. Finally, adolescent reciprocity of maternal depressive and aggressive behaviors was strongly associated with mothers' reciprocity of adolescents' negative affective behavior.  相似文献

In 1992, The Danish Medical Research Council established a national committee on scientific dishonesty with the twofold task of handling cases of scientific misconduct and taking preventive initiatives. Scientific dishonesty was proven in only five cases, but in another nine cases lesser degrees of deviations from good scientific practice were found. The experiences from a total of 24 treated cases indicated that three key areas were at the basis of most of the accusations and the deviations from good practice: uncertainty about 1) authorship, about 2) rights and duties to use scientific data and about 3) agreements at the initiation of joint studies. As a consequence guidelines on good practice have been issued on these key subjects. An earlier version of this paper was presented at a symposium, Scientific Misconduct. An International Perspective, organised by The Medical University of Warsaw, 16 November, 1998.  相似文献

The relationships between severity, chronicity, and timing of maternal depressive symptoms and child outcomes were examined in a cohort of 4,953 children. Mothers provided self-reports of depressive symptoms during pregnancy, immediately postpartum, and when the child was 6 months old and 5 years old. At the age 5 follow-up, mothers reported on children's behavior and children completed a receptive vocabulary test. Results suggest that both the severity and the chronicity of maternal depressive symptoms are related to more behavior problems and lower vocabulary scores in children. The interaction of severity and chronicity of maternal depressive symptoms was significantly related to higher levels of child behavior problems. Timing of maternal symptoms was not significantly related to child vocabulary scores, but more recent reports of maternal depressive symptoms were associated with higher rates of child behavior problems.  相似文献

Observers were presented with displays simulating a 3-D environment with obstacles in the path of motion. During the trial, observer motion decelerated at a constant rate and was followed by a blackout prior to the end of the display. On some trials the rate of deceleration resulted in stopping before the collision, whereas on other trials the rate of deceleration resulted in a collision with the obstacles. The observer's task was to detect which trials simulated an impending collision. Proportion of collision judgments was greater for older as compared with younger observers when a collision was not simulated. Older observers showed less sensitivity to detect collisions than younger observers did, particularly at high speeds. The age-dependent results are discussed in terms of analyses based on tau and constant deceleration. The results suggest that increased accident rates for older drivers may be due to an inability to detect collisions at high speeds.  相似文献

In face-to-face conversation speech is perceived by ear and eye. We studied the prerequisites of audio-visual speech perception by using perceptually ambiguous sine wave replicas of natural speech as auditory stimuli. When the subjects were not aware that the auditory stimuli were speech, they showed only negligible integration of auditory and visual stimuli. When the same subjects learned to perceive the same auditory stimuli as speech, they integrated the auditory and visual stimuli in a similar manner as natural speech. These results demonstrate the existence of a multisensory speech-specific mode of perception.  相似文献

Hindsight bias for economic developments was studied, with particular focus on the moderating effects of attitudes and causal attributions. Participants (N = 263) rated the likelihood of several economic developments 6 months before and 6 months after the euro introduction in 2002. Hindsight bias occurred selectively for attitude-consistent economic developments: Euro supporters showed stronger hindsight bias for positive developments than for negative ones; euro opponents showed the opposite pattern. Causal attribution further moderated the hindsight bias: participants who perceived a strong connection between the euro introduction and specific economic developments showed higher attitude-consistent hindsight bias than participants who perceived those developments as unrelated to the euro. It is argued that hindsight bias serves to stabilize subjective representations of the economy.  相似文献
