Natalia N. Kudryavtseva 《Aggressive behavior》2000,26(3):241-256
The sensory contact technique increases aggressiveness in male mice and allows aggressive types of behavior to be formed as a result of the repeated experience of victories in daily agonistic confrontations. Some behavioral domains confirm the development of learned aggression in males similar to those in humans. The features are repeated experience of aggression reinforced by victories; elements of learned behavior after periods of confrontation; intent, measured by increase of the aggressive motivation prior to agonistic confrontation; and decreased emotionality, estimated by parameters of open‐field behavior. Relevant situation provokes increases in aggression (boundary aggression). This review summarizes data on the influence of positive fighting experience in daily intermale confrontations on the behavior, neurochemistry, and physiology of aggressive mice (winners). This sort of experience changes many characteristics in individual and social behaviors, these having been estimated in different tests and in varied situations. Some physiological parameters are also changed in the winners. Neurochemical data confirm the activation of brain dopaminergic systems and functional inhibition of serotonergic system in winners under the influence of the repeated experience of aggression. The expression of the neurochemical and behavioral changes observed in winners has been found to depend on the mouse strain and on the duration of their agonistic confrontations. Aggr.

The aims of this paper are to study the aggressive behavior in male mice with consecutive experience of victories in 2, 10, and 20 days (T2, T10, and T20 winners) of daily agonistic confrontations under the sensory contact model and to determine the most probable behavioral domains that should be used as animal models for learned aggression in humans. It has been shown that the structure of winners' behavior changes from test to test: the attacking behavior prevailed (81% of the total time) in the behavior of T2 winners. Attacks and diggings (herein: digging up and scattering the litter on the partner' territory) prevailed in the behavior of T10 winners (each approximately 40%). T20 winners demonstrated aggressive grooming half of the testing time and digging behavior 25% of the time. Correlational analysis revealed that the number of significant correlations between the behavioral domains (attacking, digging, aggressive grooming, self‐grooming, threats, rotations) and between different behavioral parameters (latency, number, total and average time) of one behavioral domain are growing from the second test to twentieth test, and the relationships between the behavioral domains change qualitatively. The following may be regarded as elements of learned aggression in male mice: (1) appearance of aggressive grooming instead of the intensive attacking behavior and (2) involvement of the digging behavior in the hostile behavior together with the threats and attacking behavior. Negative correlations between parameters of the behavioral domains may testify to the replacement of one behavioral pattern by another and reflect learned behavior. Positive correlations between certain behavioral domains may reflect the formation of a common motivational background for the winners' behavior. Aggr.

The shape bias, a preference for mapping new word labels onto the shape rather than the color or texture of referents, has been postulated as a word‐learning mechanism. Previous research has shown deficits in the shape bias in children with autism even though they acquire sizeable lexicons. While previous explanations have suggested the atypical use of color for label extension in individuals with autism, we hypothesize an atypical mapping of novel labels to novel objects, regardless of the physical properties of the objects. In Experiment 1, we demonstrate this phenomenon in some individuals with autism, but the novelty of objects only partially explains their lack of shape bias. In a second experiment, we present a computational model that provides a developmental account of the shape bias in typically developing children and in those with autism. This model is based on theories of neurological dysfunctions in autism, and it integrates theoretical and empirical findings in the literature of categorization, word learning, and the shape bias. The model replicates the pattern of results of our first experiment and shows how individuals with autism are more likely to categorize experimental objects together on the basis of their novelty. It also provides insights into possible mechanisms by which children with autism learn new words, and why their word referents may be idiosyncratic. Our model highlights a developmental approach to autism that emphasizes deficient representations of categories underlying an impaired shape bias. 相似文献

Fifty-four older adults ranging in age from 70 to 86 years old (M = 77.54) reported daily levels of positive and negative affect, life satisfaction and daily activities for seven consecutive days. Hierarchical linear modeling (HLM) was used to investigate inter- and intra-individual effects of flow experiences on affect. Higher quality of flow was positively associated with high arousal positive affect (i.e., feeling peppy, enthusiastic, happy), negatively associated with low arousal negative affect (i.e., feeling sad and disappointed), and positively associated with life satisfaction. However, more frequent flow experiences throughout the week predicted lower average levels of positive affect and life satisfaction. Overall, the results demonstrate that flow is linked to the affective experiences of older adults, and that an individual’s overall propensity to experience flow may be influential beyond the immediate effects of a given flow experience. 相似文献

Many studies have explored the evaluative effects of vertical (up/down) or horizontal (left/right) spatial locations. However, little is known about the role of information that comes from the front and back. Basing our investigations on multiple theoretical considerations, we propose that spatial location of sounds is a cue for message valence, such that a message coming from behind is interpreted as more negative than a message presented in front of a listener. Here we show across a variety of manipulations and dependent measures that this effect occurs in the domain of social information. Our data are most compatible with theoretical accounts which propose that social information presented from behind is associated with uncertainty and lack of control, which is amplified in conditions of self-relevance. 相似文献

Despite the increasing use of self‐tracking technologies, surprisingly little empirical research has examined the effect of self‐tracking in effortful activities on consumers' task experience. Accordingly, the present research examined the moderating role of gender in the effect of self‐tracking in effortful activities on perceived competence and task experience (namely, enjoyment and subjective vitality). Across three experiments, results suggested that self‐tracking in effortful activities increases the perceived competence, enjoyment, and subjective vitality of females more than males, and that perceived competence explains these interaction effects. Interestingly, an experimental manipulation designed to prompt overestimation of abilities attenuated these positive effects among females. As such, the present research contributes to the literatures on self‐tracking and feedback instrumentality, and offers important practical implications for marketers. 相似文献

As children enter elementary school they display behavioral orientations that reveal potential developmental trajectories. Developmental transitions offer unique opportunities for examining developmental pathways and the factors that influence emerging pathways. The primary goal of this investigation was to examine characteristics of family and home contexts in predicting externalizing behavior problems among children transitioning into elementary school. Dimensions of the family and home environments of maltreated and nonmaltreated children (N = 177) were examined and used to predict externalizing behavior problems. Maltreatment was assessed using case file information, characteristics of the family and home environment were rated by interviewers, and externalizing behavior was assessed by mother's ratings on the Child Behavior Checklist. Relative to nonmaltreated children, the family environments of physically abused children were characterized by higher levels of negative social interactions. Also, in comparison to nonmaltreated children, the home environments of children who experienced neglect were characterized as less organized and clean. Hierarchical regression analyses revealed that physical abuse was the strongest predictor of externalizing behavior. After controlling for the contribution of physical abuse, mother's negative behavior toward the focal child, aggression between siblings, and the lack of an organized and clean home were each predictive of externalizing behavior. 相似文献

This review considers the role of drug therapy in the treatment of post-stroke aphasia, the evidence for efficacy of different
agents, and the theory-based explanations of drug-related benefits for aphasia rehabilitation. Pharmacological interventions
modulating stroke-induced disruption of diverse neurotransmitters may improve language and communication deficits in aphasic
patients through facilitation of brain plasticity and long-term potentiation. However, benefits are not evident for all compounds
and refinement in clinical trial designs is required. Some pharmacological trials have failed because drug treatment was not
combined with speech-language therapy, while other trials combining drugs with intensive model-driven therapies also failed
probably because of short-trial duration, inadequate sample selection, or lack of drug action. Preliminary data reveals that
combining neuroscience-based intensive aphasia techniques (constraint-induced aphasia therapy) and drugs acting on cholinergic
and glutamatergic neurotransmitter systems are associated with better outcomes than other strategies and long-term maintenance
of benefits. Although further studies are needed, current state of the evidence suggests that drug therapy may play a key
role in the treatment of post-stroke aphasia. 相似文献
