Summary Two experiments were performed to specify stimulus determinants of pattern complexity and pattern goodness. Dot patterns distributed in 3×3 and 4×4 matrices with a rectilinear frame were used in Experiment 1, and dot patterns in hexagonal frameworks with a circular frame were used in Experiment 2. The patterns were invariant for transformations of rotation or reflection, and formed symmetry groups of different orders, i.e., cyclic and dihedral groups. The complexity and goodness of the patterns depended upon such stimulus variables as follows: (1) complexity decreased with the order of symmetry groups with equal weights for cyclic and dihedral groups, whereas goodness increased with the order of both symmetry groups with different weights; (2) the simplicity and goodness of patterns with a vertical axis were greater than those with a horizontal axis and those with an oblique one; (3) the complexity of the patterns that had collinear elements with equal length was rated the simplest; (4) pattern goodness increased as a function of the number of dots and the concentrations of dot to rotation/reflection axis in 3×3 and 4 × 4 matrices. Thus, complexity and goodness of pattern differed with respect to these stimulus variables. 相似文献

The functional link between the amygdala and hippocampus in humans has not been well documented. We examined the effect of unpleasant loud noise on hippocampal and amygdaloid activities during picture encoding by means of fMRI, and on the correct response in humans. The noise reduced activity in the hippocampus during picture encoding, decreased the correct response and increased the activity of the amygdala. A path diagram using structural equation modeling suggested that hippocampus activity might be depressed by high amygdala activity. Therefore, noise should diminish memory by reducing hippocampal activity, which might be depressed by high amygdala activity. 相似文献

Individual differences in relatedness and individuality: An exploration of two constructs 总被引:1,自引:0,他引:1
Sociotropy and autonomy are two personality dimensions that relate to an individual's vulnerability to depression. Independent and interdependent self-construals are two distinctive cognitive formulations of the self derived from cross-cultural research. Both of these sets of constructs reflect self and other orientations. The purpose of the present study was to empirically examine the various factors that emerge when these two constructs are integrated. 652 participants responded to the Personal Style Inventory [Robins, C. J., Ladd, J., Welkowitz, J., Blaney, P. H., Diaz, R. & Kutcher, G. (1991). The Personal Style Inventory: Preliminary validation studies of new measures of sociotropy and autonomy. Journal of Psychopathology and Behavioral Assessment, 16, 277–300.], the Sociotropy-Autonomy Scale [Clark, D. A. & Beck, A. T. (1991). Personality factors in dysphoria: A psychometric refinement of Beck's Sociotropy-Autonomy Scale. Journal of Psychopathology and Behavioral Assessment, 13, 369–388.] and the Self-Construal Scale [Singelis, T. M. (1994). The measurement of independent and interdependent self-construals. Personality and Social Psychology Bulletin, 20, 580–591.]. Four factors emerged from a factor analysis conducted on the items of the three scales measuring sociotropy-autonomy and independent and interdependent self-construal. These four factors are discussed in the context of vulnerability to depression. 相似文献

Female Japanese students who were engaged in a calculation task were given electric shocks by a female opponent. The subjects were informed that the opponent had an intent to shock them either severely or mildly. In addition, the opponent's awareness of the outcome of attack was independently manipulated: (1) the subjects received shocks whose intensity corresponded to the opponent's intent, (2) the subjects received shocks whose intensity was inversely proportional to the intensity intended by the opponent and were informed that the opponent did not know about it, or (3) the subjects received reversed shocks as in condition (2), but were further informed that the opponent was well aware of it. An ANOVA of the measure of retaliation in terms of the intensity of shocks delivered to the opponent indicated that (1) the subjects showed more aggression of greater intensity against an opponent who apparently had an aggressive intent than the one who did not, regardless of the actual level of shock intensity; (2) when the severe attack failed, the subjects lowered aggression when the opponent was apparently aware of it as opposed to when she was not; and (3) when the subjects received severe shocks accidentally, they increased aggression when the opponent was apparently aware of it compared to when she was not. These results led us to interpret retaliation as being mediated both by the attribution of intent to the attacker and by self-presentation to the attacker and the experimenter. 相似文献

Seizure causes autonomic, neuroendocrine and stress responses. We examined the effects of kainic acid (KA)-induced seizures on the expression of the arginine vasopressin (AVP)-enhanced green fluorescent protein (eGFP) in the locus coeruleus (LC), an area known to contain noradrenergic cells, in AVP-eGFP transgenic male and female rats, with the rationale to identify stressors which induce AVP synthesis in the LC. Subcutaneous (s.c.) administration of KA caused a progressive development of seizure behavior within 24 h. AVP-eGFP fluorescence in the LC was detected 6, 24, and 48 h and 1 week after administration of KA (12 mg/kg). From a nearly undetectable level, it reached a maximum at 48 h after s.c. administration of KA and returned to the basal levels after 2 weeks. AVP-eGFP fluorescence in the LC after s.c. administration of KA was significantly reduced by the pretreatment with MK-801 (nonselective N-methyl-D-aspartate (NMDA) receptor antagonist). In the KA-administered rats, immunohistochemistry for tyrosine hydroxylase (TH) revealed that the eGFP fluorescence was co-localized with TH-immuno-reactivity in the LC. These results suggest that the synthesis of AVP-eGFP is potentially up-regulated in noradrenergic neurons in the LC after KA-induced seizures through the activation of NMDA receptors. 相似文献

From a social cognitive perspective on anger, we attempted to examine the structure of perceived norm violations and their relationships with anger. We asked 884 university students from 4 countries (United States, Germany, Japan, and Hong Kong) to rate their experiences of being harmed in terms of norm violations, angry feelings, blame, and relationship with the harm doers. We found 2 culturally common dimensions in perceived norm violations (informal interpersonal norms and formal societal norms), and these dimensions substantially increased both angry feelings and blame in almost all cultural groups. The violation of interpersonal norms generally evoked anger more frequently than that of societal norms, but there were interactions between culture and relationship closeness and between gender and relationship closeness. 相似文献

In this case study, HY had lived in a persistent vegetative state for 6 years after onset of encephalitis at age 10. His processing of emotionally and socially meaningful information was impaired by the age of 20, as it is in individuals with amygdala damage; however, his performance on tasks requiring understanding a "theory of mind" improved by age 22. A series of responses to photographs of facial expressions and to a gambling task were obtained to evaluate his functioning related to the amygdala. He was particularly impaired in recognizing fear. One may tentatively suggest that processing emotional signals, i.e., functioning related to the amygdala, may not play an important role in the neural systems supporting development of understanding a "theory of mind". 相似文献

Sociotropy and autonomy are conceptualized as two personality dimensions that relate to an individual's vulnerability to depression. Sociotropy is characterized as an excessive investment in interpersonal relationships and autonomy is characterized as an excessive concern with personal achievement and control over the environment. The present research project consisted of two studies examining the relationships between sociotropy–autonomy and interpersonal patterns in close relationships. Data collected via self‐report and behavioural observations suggested that highly sociotropic individuals have a tendency to be high in control and low in affiliation towards individuals who are close to them. In contrast, the data suggested that highly autonomous individuals may be low in both control and affiliation towards people who are close to them. These findings are discussed in the context of the literature regarding the interpersonal characteristics of sociotropic and autonomous individuals. 相似文献
