We describe a theory to account for the acquisition and extinction of response rate (conditioning) and pattern (timing). This
modular theory is a development of packet theory (Kirkpatrick, 2002; Kirkpatrick & Church, 2003) that adds a distinction between
pattern and strength memories, as well as contributing closed-form equations. We describe the theory using equations related
to a flow diagram and illustrate it by an application to an experiment with repeated acquisitions and extinctions of a multiple-cued-interval
procedure using rats. The parameter estimates for the theory were based on a calibration sample from the data, and the predictions
for different measures of performance on a validation sample from the same data (cross-validation). The theory’s predictions
were similar to predictions based on the reliability of the behavior. 相似文献

The current study examined the role of maternal behaviour and toddlers' emotion regulation strategies in the development of children's sustained attention abilities. Participants for this study included 447 children (232 girls) obtained from three different cohorts participating in a larger ongoing longitudinal study. When the children were 2 years of age, mothers brought their children to the laboratory and were videotaped during several tasks designed to elicit emotion regulation and mother–child interaction. Sustained attention was also measured at the same visit via a laboratory task and in a subsequent visit when children were 4.5 years of age. Results indicated that toddlers' use of help‐seeking emotion regulation strategies was positively related to sustained attention, while avoidance behaviours and maternal behaviour characterized by high levels of overcontrolling/intrusiveness were negatively related to sustained attention at age 2. Significant interactions emerged such that high levels of maternal warmth/responsiveness buffered the negative associations between low use of distraction and high use of self‐comforting emotion regulation strategies and sustained attention at age 2. Maternal behaviour characterized by high levels of warmth/responsiveness also predicted greater growth in sustained attention from age 2 to 4.5. These findings are discussed in terms of how maternal behaviours and children's use of active versus passive emotion regulation strategies relate to sustained attention abilities.

The paper discusses what the author calls “The seduction by the father”. It would occur when, in the Oedipus complex, the father reverses his role: instead of being the one who castrates, he seduces. Seduction here is understood in the sense that he does not act as the one who imposes limits to the child. Consequently the child can not project his hostile impulses onto the father. Based on clinical data, the Author says that, in the male child, the seduction by the father hampers the transformation of the two Oedipal attitudes towards the father into identifications. The consequences of this fact upon the construction of the “nostalgia of the father's protection” are discussed, so as the transformation of this father into the symbolic father. 相似文献

We analyzed the role of both attachment anxiety and attachment avoidance as a mediators of the effects of combat exposure on posttraumatic stress disorder (PTSD) symptoms. Participants were Portuguese veterans (N = 60) divided into 2 groups: 30 suffered from chronic PTSD (nonrecovered) and 30 had remission from PTSD (recovered). Combat exposure, attachment patterns, and PTSD symptoms were assessed through self-report measures. Mediation test was performed by conducting several hierarchical regression analyses. Results showed higher attachment anxiety among nonrecovered participants. We did not find statistically significant differences between groups for both attachment avoidance and combat exposure level scores. In mediation analysis, at first step, attachment avoidance was not a significant predictor of PTSD symptoms, and attachment avoidance did not enter in subsequent analysis. Attachment anxiety was a partial mediator of the effect of combat exposure on PTSD symptoms. Implications of the findings for both attachment theory and clinical intervention on trauma are discussed. 相似文献

Anger may be more responsive than disgust to mitigating circumstances in judgements of wrongdoing. We tested this hypothesis in two studies where we had participants envision circumstances that could serve to mitigate an otherwise wrongful act. In Study 1, participants provided moral judgements, and ratings of anger and disgust, to a number of transgressions involving either harm or bodily purity. They were then asked to imagine and report whether there might be any circumstances that would make it all right to perform the act. Across transgression type, and controlling for covariance between anger and disgust, levels of anger were found to negatively predict the envisioning of mitigating circumstances for wrongdoing, while disgust was unrelated. Study 2 replicated and extended these findings to less serious transgressions, using a continuous measure of mitigating circumstances, and demonstrated the impact of anger independent of deontological commitments. These findings highlight the differential relationship that anger and disgust have with the ability to envision mitigating factors. 相似文献

This study focused on the influence of selective exposure within an experiment designed to investigate context effects on advertising effectiveness. In a semi‐natural viewing environment, 86 participants chose one of four television programmes to view. The programmes belonged to diverse genres: news and current affairs, light entertainment, sport, and action‐adventure. Each programme was interrupted by two commercial breaks containing unfamiliar advertisements for familiar product types. Self‐rated involvement, entertainment, and enjoyment of programmes correlated positively with subsequent measures of memory for and responses to the advertisements. The results support the hypothesis that the operation of selective exposure within an experimental situation may result in positive relationships between predictor variables and measures of advertisement effectiveness.

Two experiments examined how pigeons differentiate response patterns along the dimension of number. In Experiment 1, 5 pigeons received food after pecking the left key at least N times and then switching to the right key (Mechner's Fixed Consecutive Number schedule). Parameter N varied across conditions from 4 to 32. Results showed that run length on the left key followed a normal distribution whose mean and standard deviation increased linearly with N; the coefficient of variation approached a constant value (the scalar property). In Experiment 2, 4 pigeons received food with probability p for pecking the left key exactly four times and then switching. If that did not happen, the pigeons still could receive food by returning to the left key and pecking it for a total of at least 16 times and then switching. Parameter p varied across conditions from 1.0 to .25. Results showed that when p= 1.0 or p=.5, pigeons learned two response numerosities within the same condition. When p=.25, each pigeon adapted to the schedule differently. Two of them emitted first runs well described by a mixture of two normal distributions, one with mean close to 4 and the other with mean close to 16 pecks. A mathematical model for the differentiation of response numerosity in Fixed Consecutive Number schedules is proposed. 相似文献

In this paper, the author starts by examining the recent occurrence of an increasing receptivity and critical exchange between different schools of psychoanalytical thought. Among its consequences have been convergences in the understanding of countertransference, especially through the hypotheses of projective identification and countertransferential enactment. The prevalence of these hypotheses points towards the fact that the community of analysts is bringing about an informal and convergent clinical research conducted by a wide and heterogeneous range of its members. The importance and epistemological relevance of this kind of 'informal clinical research' for the construction of psychoanalytical knowledge is emphasised. This process in psychoanalysis is compared with the evolution of knowledge in other scientific areas, highlighting their similarities and their differences. The author shows how Freud's 'mystic writing-pad'model can be expanded to represent the object of psychoanalytical investigation and to bring a better understanding of the reason why the hypotheses of projective identification and countertransferential enactment occupy such a central position in psychoanalysis. In addition, consideration is given to how this kind of research can help in the difficult task of finding criteria for the evaluation of different psychoanalytical concepts. Finally, the author demonstrates how, using this approach, some of the important divergences in contemporary psychoanalysis can be viewed from a new perspective. 相似文献

This paper is concerned with a specific type of problem, namely dynamic decisions, for which most techniques fail to provide adequate solutions. Here, we present two of the most promising optimization techniques, partially observable Markov decision processes (POMDP) and dynamic decision networks (DDN), while arguing which is the most suitable for this problem domain.

The aim of the current study was to examine the moderating effect of baseline respiratory sinus arrhythmia (RSA) on Parent-Child Interaction Therapy (PCIT), a behavioral parent-training intervention, for young children born premature. In this pilot randomized controlled trial, 28 young children (mean age of 37.79 months), who were born <37 weeks gestation and presented with elevated externalizing behavior problems, were randomly assigned to an immediate treatment or waitlist control group. RSA, which provides an approximate marker of individual differences in cardiac vagal tone, was measured during a baseline period. Past research has generally shown that higher levels of baseline RSA correlate with various positive psychological states (e.g., empathy, sustained attention), whereas lower levels of baseline RSA correlate with less optimal psychological states (e.g., higher externalizing behavior problems). Results indicated that baseline RSA significantly interacted with treatment condition in predicting changes in child disruptive behavior. Specifically, low levels of baseline RSA were associated with greater improvements in child disruptive behavior following PCIT. While acknowledging the caveats of measuring and interpreting RSA and the need to include a sympathetic-linked cardiac measure in future research, these findings provide preliminary evidence that children with lower capacity for emotion regulation receive even greater treatment gains. Future research should also examine the moderating effect of RSA in larger samples and explore the potential mediating role of RSA on behavioral parenting interventions. 相似文献
