Balanced bilinguals have been shown to have an enhanced ability to inhibit distracting information. In this study, we investigated
the hypothesis that the bilinguals’ efficiency in inhibitory control can be advantageous in some conditions, but disadvantageous
in others—for example, negative priming conditions, in which previously irrelevant information becomes relevant. Data collected
in a target-stimulus locating task from 29 early bilingual adults and 29 age-matched monolinguals showed that the bilinguals’
greater inhibition of irrelevant spatial information (i.e., the position of a distractor stimulus) resulted in a smaller effect
of the distractor presence (i.e., a smaller difference in error rates in trials with and without distractors) and a larger
negative priming effect (i.e., a larger difference between the error rates shown in trials wherein the target position corresponded
to the position of the previous-trial distractor and trials wherein the target was presented in a previously vacant position).
These findings support the hypothesis of specific nonlinguistic cognitive effects of bilingualism on inhibitory control functions,
which are not necessarily reflected in cognitive advantages. 相似文献

Previous research has demonstrated separation between systems supporting memory for appearance and memory for location. However, the interpretation of these results is complicated by a confound occurring because of the simultaneous presentation of objects in multiple-item arrays when assessing memory for appearance and the sequential presentation of items when assessing memory for location. This paper reports an experiment in which sequential or simultaneous modes of presentation were factorially manipulated with memory for visual appearance or memory for location. Spatial interference (tapping) or visual interference (dynamic visual noise) were presented during retention. Appearance versus location interacted with the type of interference task, but mode of presentation did not. These results are consistent with the view that different subsystems within visuo-spatial working memory support memory for appearance and memory for location. 相似文献

Classical amnesia involves selective memory impairment for temporally distant items in free recall (impaired primacy) together
with relative preservation of memory for recency items. This abnormal serial position curve is traditionally taken as evidence
for a distinction between different memory processes, with amnesia being associated with selectively impaired long-term memory.
However recent accounts of normal serial position curves have emphasized the importance of rehearsal processes in giving rise
to primacy effects and have suggested that a single temporal distinctiveness mechanism can account for both primacy and recency
effects when rehearsal is considered. Here we explore the pattern of strategic rehearsal in a patient with very severe amnesia.
When the patient’s rehearsal pattern is taken into account, a temporal distinctiveness model can account for the serial position
curve in both amnesic and control free recall. The results are taken as consistent with temporal distinctiveness models of
free recall, and they motivate an emphasis on rehearsal patterns in understanding amnesic deficits in free recall. 相似文献

Even though injury and death are more common consequences of fighting among animals than once believed, they are still relatively infrequent. Modern evolutionary models of animal combat have emphasized that given the threat of retaliation, animals only escalate to more injurious fighting if the benefits outweigh the costs, and then only if threat and bluff fail to achieve the goal. Such models stress the role of communication as to whether animals decide to escalate or not. An alternative view is that failure to produce injury or death arises from the neutralization of one animal's attack by another's defense. That is, attack and defense end in a stalemate that may be misinterpreted by outside observers as an absence of injury producing behavior. As attack typically involves the biting or striking of specific body targets, movements and postures occurring during combat need to be analyzed with respect to their role in gaining or averting such contact. For example, in the combat of muroid rodents the attacker targets the lower dorsum and flanks (low threshold) or face (high threshold), whereas a defender may defensively launch counterstrikes against the attacker's face. Two combat tactics (supine defense and lateral attack) typically present in the fighting of muroid rodents are analyzed in detail to illustrate how targets constrain the movements of combatants. Such a functional analysis of combat assumes that the movements and postures performed are related to their role in the attack and defense of targets. Deviations from such a strict functional interpretation reveal some of the other factors that may constrain the combatants' behavior. For example, body morphology and the aggressiveness of the opponent are shown to be important in deciding the type of combat tactic to use and how it is performed. Finally, movements and postures that are neutral or even counterproductive for attack and defense may be revealed as communicatory. This approach provides a means of analyzing behavior during the "heat of combat" that is typically not dealt with in traditional evolutionary models. Aggr.

The play fighting of many mammals involves the nonserious use of behavior patterns derived from serious fighting. A major question of theoretical importance has been that of how, given this overlap in patterns of behavior, the animals can distinguish between playful and nonplayful intent. One proposed solution is that animals use play signals to inform each other about the playful intent of their actions. The most widely reported play signal amongst primates is the open mouth play face. The manner in which this so-called signal functions is based on correlational evidence, with most reports simply noting its presence or absence in a given species. This study involved a detailed video-based analysis of the occurrence of open mouths during the play fighting of three species of primates. One captive troop each of ring-tailed lemurs, black-handed spider monkeys, and patas monkeys was used. By examining all open mouths in the context of the species-typical style of play fighting, several conclusions were empirically verified. 1) Most open mouths occur as a functionally necessary precursor for biting. 2) Some open mouths occur as a defensive threat which deters further contact. 3) The residual open mouths which may function as contact promoting play signals, constituted about 20–25% of all open mouths by the lemurs and patas monkeys, but less than 5% for spider monkeys. These species differences appeared to arise from two causes. Firstly, the spider monkeys used another signal, the head shake, in situations where lemurs and patas monkeys used open mouths. Secondly, the style of play fighting greatly influenced the frequency and duration of open mouths. This was most marked in the face-to-face combat style of patas monkeys. These findings show that comparative studies of the occurrence and function of play signals need to take into account species-typical styles of playful combat. Aggr.

Feeding rats defend a food item from an approaching conspecific by turning away, laterally, about 180°. Females and males use a different composition of movements and stepping patterns to perform these defensive dodges. This study was designed to examine the role of the robber's sex on the execution of sex-typical patterns of dodging. All subjects were tested with a partner of each sex. During dodging, females used the female-typical pattern of pivoting around the pelvis, and males used the male-typical midbody pivot, irrespective of the robber's sex. These findings show that the sex-typical patterns of dodging are not determined by the sex of the partner. Females and males however, differed in how they were oriented towards a same sex robber at the end of the dodge. This suggests that while male and female robbers must pose different defensive problems, these differences are dealt with by modifying the sex-typical pattern of dodging rather than by switching to the dodge pattern of the opposite sex. This further suggests that the differences in the composition of the dodge pattern in males and females are not due to extrinsic contingencies, but rather, are due to intrinsic differences in the sex-typical organization of defensive motor patterns.

Three experiments investigated mediated configural learning in male rats. In Experiment 1, after exposure to audio-visual compounds AX and BY, rats received trials where X was paired with shock, and Y was not. The idea that conditioning with X enables the evoked configural representation of AX to be linked to shock received support from the facts that while AX provoked more fear than BX, there was no difference between BY and AY. Similarly, Experiment 2 showed that after exposure to AX and BY, separate pairings of X and Y with shock resulted in more fear to AX and BY than AY and BX. In Experiment 3, rats in group consistent received separate exposures to A and X in Context C, and B and Y in D, while those in group inconsistent received A and X (and B and Y) in both C and D. After rats had received shocks in both C and D, rats in group consistent showed more fear to AX and BY than to BX and AY, but this was not the case in group inconsistent. These results indicate that configural representations, formed either by presenting auditory and visual stimuli as parts of a compound or in a shared context, are subject to a process of mediated learning. 相似文献

The present study focuses on the interplay of emotion‐regulation ability and perceived workplace social support as predictors of job satisfaction and happiness in a Spanish multi‐occupational sample. A total of 494 working adults (39.4% females) took part in this study. Emotion‐regulation ability and perceived support from colleagues and supervisors were positively associated. In addition, emotion‐regulation ability and perceived support from colleagues and supervisors showed positive associations with job satisfaction and happiness. Furthermore, considering results from moderation analyses, when low levels of perceived workplace social support were reported, the relationship between emotion regulation and both job satisfaction and happiness was stronger than in cases of higher perceived workplace support. In line with previous studies, these findings suggest that training in emotion regulation abilities may take into consideration the potential moderating role of job characteristics such as support from colleagues and supervisors. Finally, theoretical and practical implications of the joint study of these factors in line with the Job Demands‐Resources model and the Emotional Intelligence framework are discussed. 相似文献
