Although mothers of young children have a higher incidence of depressive symptomatology than do either women who are not mothers or men, very little is known about the psychological nature of this phenomenon. This study examines the way in which psychological dimensions of family relationships are associated with or contribute to this increased risk in married Caucasian mothers raising first-born children. The relationships between maternal depressive symptomatology and recollections of parental relationships during childhood, marital satisfaction, and maternal separation anxiety were examined. Hierarchical regression analyses revealed that these three factors explained 35.5% of the variance in maternal depressive symptomatology. These results, in addition to significant zero-order correlations, are discussed in light of the existing psychological literature. 相似文献

The study investigated the influence of cognitive avoidance, positive affect, and gender on the evaluation of and memory for threat-related information varying in degrees of aversiveness and ambiguity. Stimulus material consisted of threatening, nonthreatening, and ambiguous pictures. First, valence ratings of the stimuli were collected. This phase was followed by a first memory test. A second memory test was administered three days later. Memory for aversive information was influenced by cognitive avoidance, positive affect, and gender. Avoiders exhibited a comparatively good memory for aversive information in the first (immediate) test and a very poor memory in the delayed testing. A similar pattern was obtained for individuals high in positive affect. Compared to men, women gave more negative ratings to aversive and ambiguous pictures and had a better memory for ambiguous information in the immediate test. Results are discussed within the framework of the repressive discontinuity hypothesis proposed by Hock and Krohne [Hock, M., Krohne, H. W. (2004). Coping with threat and memory for ambiguous information: Testing the repressive discontinuity hypothesis. Emotion, 4, 65–86]. 相似文献

Four motion quartets, each ambiguous with respect to the perception of parallel-path horizontal or vertical motion, were arranged in a diamond configuration. Both global parallel-path motion (the same motion axis for all the quartets), which is typical for multiquartet stimuli, and global rotational rocking are perceived. Experiment 1 indicated that rotational rocking is established at different levels of processing. Globally, larger displacements of each quartet's elements increase the angle of rotation and, thereby, the perception of rotational rocking. Locally, larger displacements have the opposite effect, weakening motion percepts. Experiment 2 showed that global-to-local feedback affects the local perception of rotation-consistent versus rotation-inconsistent motion directions. Experiment 3 provided evidence for hysteresis effects indicative of competition between global rotational rocking and parallel-path motion. The experimental results were simulated by a two-level dynamical model incorporating global-to-local feedback, with recurrent feedforward/feedback loops creating detection instabilities that amplify activation at both global and local levels of the rotational-rocking pattern. 相似文献

ABSTRACTThe differentiation of trait anxiety and depression in nonclinical and clinical populations is addressed. Following the tripartite model, it is assumed that anxiety and depression share a large portion of negative affectivity (NA), but differ with respect to bodily hyperarousal (specific to anxiety) and anhedonia (lack of positive affect; specific to depression). In contrast to the tripartite model, NA is subdivided into worry (characteristic for anxiety) and dysthymia (characteristic for depression), which leads to a four-variable model of anxiety and depression encompassing emotionality, worry, dysthymia, and anhedonia. Item-level confirmatory factor analyses and latent class cluster analysis based on a large nation-wide representative German sample (N?=?3150) substantiate the construct validity of the model. Further evidence concerning convergent and discriminant validity with respect to related constructs is obtained in two smaller nonclinical and clinical samples. Factors influencing the association between components of anxiety and depression are discussed. 相似文献

The aim of this study was to develop a conceptual model that would clarify how a woman's recollections of peer and parent rejection in childhood influence her emotional well-being and, resultantly, her own child's behavior problems. Given current interest in peer versus parent influences, the authors used a design and analysis to reveal the unique contributions of peer and parent rejection. The participants were a community sample of 88 mothers and their 2 1/2-year-old children. The study found that mothers' recollections of peer rejection in childhood were significantly associated with depressive symptomatology, but recollections of parental rejection in childhood were unrelated to current depressive symptoms. Recollections of peer rejection during childhood, internal representation of self, and depressive symptoms made significant, unique contributions to the variance in behavior problems in their children. Together, these variables significantly explained 27% of the variance in the final model. 相似文献

A computational model for the perception of counterchange-specified motion is examined in detail and compared with various versions of the Reichardt motion detection model [Reichardt, W. (1961). Autocorrelation, a principle for the evaluation of sensory information by the central nervous system. In W. A. Rosenblith (Ed.), Sensory communication (pp. 303-317). New York: Wiley]. The counterchange model is composed of a pair of temporally biphasic subunits at two retinal locations, one detecting decreases and the other increases in input activation. Motion is signaled when both subunits are simultaneously excited, as determined by the multiplicative combination of their transient responses. In contrast with the Reichardt detector, which effectively tracks motion energy and accounts solely for results obtained with standard apparent motion stimuli (a surface is visible at one location, then at another), the counterchange model also accounts for the generalized apparent motion perceived between pairs of simultaneously visible surfaces. This indicates that standard apparent motion can be perceived via the same non-sequential, non-motion-energy mechanism as generalized apparent motion. There is no need for either an explicit delay mechanism to account for optimal motion perception at non-zero inter-stimulus intervals, or for inhibitory interaction between subunits to account for the absence of motion in the detector’s null direction (Barlow, H. B., & Levick, W. R., 1965). Both are emergent properties that result from the inhibitory states of the counterchange detector’s biphasic subunits. In addition to apparent motion, the counterchange principle potentially accounts for the perception of motion for drifting gratings, the short range motion perceived for random-dot cinematograms, and the motion perceived for continuously moving objects. 相似文献

Abstract The “two-process model” postulates that there are specific associations between patterns of parental child-rearing styles and the development of the child's anxiety and coping dispositions. Besides parameters of parental feedback to the child, this model considers support and restriction to be the central dimensions of child-rearing behavior. The present study aims at assessing behavioral indicators for restriction. For this purpose, the working and intervention behavior of 47 mothers and their ten- to 13-year-old children was observed and registered during a 15-minute period of common problem-solving (putting together a difficult puzzle-like cube). In order to register processes of problem-oriented cooperation between mother and child, transitional probabilities between defined state and event classes were analyzed. Based on the theoretical definition of the child-rearing style “restrictio”, hypotheses concerning the significance of variable transitional probabilities are formulated and tested regarding their correspondence with anxiety-related characteristics of the child. 相似文献

Wertheimer, M. (Zeitschrift für Psychologie und Physiologie der Sinnesorgane, 61:161–265, 1912) classical distinction between beta (object) and phi (objectless) motion is elaborated here in a series of experiments concerning competition between two qualitatively different motion percepts, induced by sequential changes in luminance for two-dimensional geometric objects composed of rectangular surfaces. One of these percepts is of spreading-luminance motion that continuously sweeps across the entire object; it exhibits shape invariance and is perceived most strongly for fast speeds. Significantly for the characterization of phi as objectless motion, the spreading luminance does not involve surface boundaries or any other feature; the percept is driven solely by spatiotemporal changes in luminance. Alternatively, and for relatively slow speeds, a discrete series of edge motions can be perceived in the direction opposite to spreading-luminance motion. Akin to beta motion, the edges appear to move through intermediate positions within the object’s changing surfaces. Significantly for the characterization of beta as object motion, edge motion exhibits shape dependence and is based on the detection of oppositely signed changes in contrast (i.e., counterchange) for features essential to the determination of an object’s shape, the boundaries separating its surfaces. These results are consistent with area MT neurons that differ with respect to speed preference Newsome et al (Journal of Neurophysiology, 55:1340–1351, 1986) and shape dependence Zeki (Journal of Physiology, 236:549–573, 1974). 相似文献

Adults’ face processing expertise includes sensitivity to second-order configural information (spatial relations among features such as distance between eyes). Prior research indicates that infants process this information in female faces. In the current experiments, 9-month-olds discriminated spacing changes in upright human male and monkey faces but not in inverted faces. However, they failed to process matching changes in upright house stimuli. A similar pattern of performance was exhibited by 5-month-olds. Thus, 5- and 9-month-olds exhibited specialization by processing configural information in upright primate faces but not in houses or inverted faces. This finding suggests that, even early in life, infants treat faces in a special manner by responding to changes in configural information more readily in faces than in non-face stimuli. However, previously reported differences in infants’ processing of human versus monkey faces at 9 months of age (but not at younger ages), which have been associated with perceptual narrowing, were not evident in the current study. Thus, perceptual narrowing is not absolute in the sense of loss of the ability to process information from other species’ faces at older ages. 相似文献
