To date, research on the relation between learning self-regulation and academic achievement has generally show disparate results. This work intends to look into this relation from a new perspective, which consists in classifying the students as more or less self-regulated depending on diverse indicators and using cluster analysis. The aim of this work was to identify the possible self-regulated learning profiles in a sample of university students. By means of stepwise linear regression analysis, we determined which of the selected variables better predicted metacognitive self-regulation. Then, three significantly different self-regulated learning profiles were obtained by two-step cluster analysis with those variables. Lastly, ANOVA was used to analyse the relation between the self-regulated learning profiles and academic achievement. The implications of these data for the educational practice at university are discussed. 相似文献

We examined the influence of individual psychological profile and social behavior on tumor development in dominant male mice. Male OF1 mice were subjected to an open field test (OFT) to observe their motor activity and latency. Subsequently, the animals were divided into three groups: Stress-Non-Inoculated (SNI), Stress-Inoculated (SI) and Control-Inoculated (CI). The SI and CI groups were inoculated with tumor cells and the SNI group with vehicle. SNI and SI were exposed to social stress with an anosmic intruder six (T1) and twenty one (T2) days after inoculation and their behavior was analyzed. After T2, subjects were put down and the pulmonary metastatic foci counted. SI developed greater pulmonary metastasis than CI, indicating an effect of stress despite the animal's dominant status. Active animals developed less pulmonary metastasis than their passive counterparts. No differences were found in social behavior at T1. Differences were found, however, in some behavioral categories at T2 between SI and SNI, and between active and passive animals. These differences indicate an effect of tumor development on social behavior that is more evident in passive subjects. 相似文献

In this article, a method is presented to analyse relationships between detection or discrimination frequencies and reaction times in psychophysical tasks. It is shown in three empirical data sets that reaction time decreases as a linear function of the absolute value of the logit transforms of the response probabilities. Such a function stresses the characteristic uncertainty associated with subjects' responses and the relation between their response parameters and the response criterion used by the subjects. 相似文献

The purpose of this study is to analyse the evolution of gender perspective in the context of the Spanish academic Psychology. The last three decades were analysed. In each decade, the study describes the groups and individuals who have contributed to the analysis of gender perspective in Psychology, the sponsoring institutions, and the most frequently used research strategies. Likewise, the study analyses the development of topics and areas in these three decades. The general trend shows that the interpretation of sex/gender has moved away from being considered an individual and internal factor to a more dynamic approach that analyses sex/gender through behavioural practices. 相似文献

In this paper, a study of personality disorders and psychopathy in imprisoned male batterers is carried out. A sample of 76 batterers sentenced for a severe offence of violence against their intimate partner was selected. All the participants were assessed with the MCMI-II before beginning a treatment program in prison for gender violence. Likewise, all participants were assessed with the PCL-R in order to identify psychopathic symptoms. According to the results, 86.8% of the sample showed at least one personality disorder. The most prevalent one was the Obsessive-compulsive Personality Disorder (57.8% of cases), followed by the Dependent Personality Disorder (34.2% of cases) and Paranoid Personality Disorder (25%). Regarding psychopathy, the results of PCL-R showed that there were 11 people (14.4% of the sample) who met the criteria for psychopathy or probable psychopathy. Finally, implications of this study for clinical practice and future research in this field are commented upon. 相似文献

In this paper, an evaluation of Cloninger's typology of alcohol abuse in personality, psychopathology and personality disorders is carried out. The sample consisted of 158 alcoholics in treatment (56 Type I alcohol-dependent patients and 102 Type II alcohol-dependent patients). All subjects were assessed with diverse assessment tools related to personality (Impulsiveness Scale, Sensation Seeking Scale and STAI), psychopathology (SCL-90-R, BDI and Inadaptation Scale) and personality disorders (IPDE). The main findings were that Type II alcohol-dependent patients were more impulsive and sensation-seeking and they displayed more hostility and emotional distress than Type I alcohol-dependent patients. Personality disorders were not so prevalent in the case of Type I alcohol-dependent patients. The most specific personality disorders for Type II alcohol-dependent patients were narcissistic and paranoid. The implications of this study for further research are commented on. 相似文献

We evaluated the effects of 2 types of training on the emergence of bidirectional intraverbal relations with 4 typically developing children. Tact training involved reinforcing foreign-language vocalizations in the presence of visual stimuli, and listener training involved reinforcing selections of visual stimuli following vocal presentations of foreign-language words. Intraverbal relations were tested by instructing participants to vocalize native-language equivalents of foreign-language words or vice versa. Both types of training produced increases in intraverbal responding, but the emergent relations were not always bidirectional. 相似文献

The authors investigated the effect of the opioid antagonist naloxone on wheel-running behavior in Balb/c mice. Naloxone delayed the acquisition of wheel-running behavior, but did not reduce the expression of this behavior once acquired. Delayed acquisition was not likely a result of reduced locomotor activity, as naloxone-treated mice did not exhibit reduced wheel running after the behavior was acquired, and they performed normally on the rotarod test. However, naloxone-blocked conditioned place preference for a novel compartment paired previously with wheel running, suggesting that naloxone may delay wheel-running acquisition by blocking the rewarding or reinforcing effects of the behavior. These results suggest that the endogenous opioid system mediates the initial reinforcing effects of wheel running that are important in acquisition of the behavior. 相似文献

Loach and Marí-Beffa (Vis Cogn, 10:513-526, 2003) observed that a distractor stimulus, presented immediately after a behaviorally relevant target stimulus, negatively primed a related probe stimulus indicating that the distractor had been inhibited. They argued that "post-target inhibition" may be a mechanism for preventing interference from temporally proximal stimuli; interference that could potentially result in a binding/intrusion error. In order to test this hypothesis, the authors carried out two rapid serial visual presentation (RSVP) experiments in which participants had to report either the identity (Experiment 1) or color (Experiment 2) of a target letter surrounded by distractor letters. In Experiment 1, a close relationship between priming and errors was observed. When a distractor stimulus showed evidence of being inhibited the participant was less likely to commit a binding error. The opposite was true when a distractor stimulus showed evidence of being facilitated. The results of Experiment 2 showed limited evidence of the same relationship. 相似文献

People often infer expertise from the choice of unique, rare, or sophisticated options. But might mere variety‐seeking also serve as a signal of expertise, and if so, how? Six studies show that the relationship between variety‐seeking and perceived expertise is not unidirectional and depends on the perceiver's own level of expertise. Category experts perceive lower variety‐seeking as indicative of discernment, which in turn increases perceived expertise in that category. Consequently, experts choose less variety to portray themselves as experts. In contrast, novices perceive high variety‐seeking as indicative of category breadth knowledge, which in turn increases their perception of category expertise. Consequently, novices choose more variety to portray themselves as experts. The findings make novel theoretical contributions to research on variety‐seeking, consumer expertise, and social perception, as well as practical contributions for marketers of product assortments and bundles. 相似文献
