Reduced neural activation have been consistently observed during repeated items processing, a phenomenon termed repetition suppression. The present study used functional magnetic resonance imaging (fMRI) to investigate whether and how stimuli of emotional valence affects repetition suppression by adopting Chinese personality‐trait words as materials. Seventeen participants were required to read the negative and neutral Chinese personality‐trait words silently. And then they were presented with repeated and novel items during scanning. Results showed significant repetition suppression in the inferior occipital gyrus only for neutral personality‐trait words, whereas similar repetition suppression in the left inferior temporal gyrus and left middle temporal gyrus was revealed for both the word types. These results indicated common and distinct neural substrates during processing Chinese repeated negative and neutral personality‐trait words. 相似文献

Rhythmic grouping enhances verbal serial recall, yet very little is known about memory for rhythmic patterns. The aim of this study was to compare the cognitive processes supporting memory for rhythmic and verbal sequences using a range of concurrent tasks and irrelevant sounds. In Experiment 1, both concurrent articulation and paced finger tapping during presentation and during a retention interval impaired rhythm recall, while letter recall was only impaired by concurrent articulation. In Experiments 2 and 3, irrelevant sound consisted of irrelevant speech or tones, changing-state or steady-state sound, and syncopated or paced sound during presentation and during a retention interval. Irrelevant speech was more damaging to rhythm and letter recall than was irrelevant tone sound, but there was no effect of changing state on rhythm recall, while letter recall accuracy was disrupted by changing-state sound. Pacing of sound did not consistently affect either rhythm or letter recall. There are similarities in the way speech and rhythms are processed that appear to extend beyond reliance on temporal coding mechanisms involved in serial-order recall. 相似文献

We investigated whether the basic process of integrating stimuli (and their features) with simultaneously executed responses transfers to situations in which one does not respond to a stimulus. In three experiments, a stop-signal task was combined with a sequential priming paradigm to test whether irrelevant stimulus features become associated with a “stop” tag. Stopping a simple response during the prime trial delayed responding and facilitated stopping in the probe if the same irrelevant stimulus feature was repeated in the probe. These repetition priming effects were independent of the relation between the to-be-executed (or to-be-stopped) responses in the prime and probe, indicating that “stop” tags are global (“stop all responses!”) rather than being response-related (e.g., “stop left response!”). 相似文献

Concurrent tasks, such as articulatory suppression and manual tapping, are used to understand the mechanisms underlying short-term memory by overloading domain-specific resources. The present study addresses the debate regarding the theoretical frameworks accounting for interference in serial recall by comparing the effects of both the modality of concurrent tasks (verbal vs. spatial) as well as the state of the tasks (steady vs. changing) in both verbal and spatial recall. The findings indicate that the verbal changing-state concurrent task significantly impaired digit recall, whereas the spatial changing-state concurrent task significantly impaired block recall. The theoretical implications are discussed in the context of a multimodal working memory model with domain-specific resources and a unitary approach to short-term memory. 相似文献

The potential mediating roles of parental warmth and inductive discipline on the relations of parental emotion regulation strategies to children’s prosocial behavior were examined in this study. Sixty-four parents of preschoolers (50% girls) completed questionnaires assessing their own regulation practices (i.e., cognitive reappraisal, expressive suppression), parenting behaviors (i.e., parental warmth/nurturance, inductive discipline), and children’s prosocial behavior (voluntary behavior intended to benefit another). The authors hypothesized that cognitive reappraisal would be positively and expressive suppression would be negatively related to parenting behaviors and children’s prosocial behavior. They further hypothesized that parental warmth and inductive discipline would mediate the relations between parents’ own regulation strategies and children’s prosocial behavior. Results demonstrated that parental cognitive reappraisal was positively associated with warmth, and expressive suppression was negatively associated with inductive discipline and children’s prosocial behavior. Parental warmth, but not inductive discipline, mediated the relations between cognitive reappraisal and children’s prosocial behavior. The results highlight adults’ own regulatory strategies as predictors of socialization behaviors and the potential processes for socialization of children’s moral emotions and positive social development. 相似文献

The mu rhythms (8–13 Hz) and the beta rhythms (15 up to 30 Hz) of the EEG are observed in the central electrodes (C3, Cz and C4) in resting states, and become suppressed when participants perform a manual action or when they observe another’s action. This has led researchers to consider that these rhythms are electrophysiological markers of the motor neuron activity in humans. This study tested whether the comprehension of action language, unlike abstract language, modulates mu and low beta rhythms (15–20 Hz) in a similar way as the observation of real actions. The log-ratios were calculated for each oscillatory band between each condition and baseline resting periods. The results indicated that both action language and action videos caused mu and beta suppression (negative log-ratios), whereas abstract language did not, confirming the hypothesis that understanding action language activates motor networks in the brain. In other words, the resonance of motor areas associated with action language is compatible with the embodiment approach to linguistic meaning. 相似文献

In order to interpret a constantly changing environment, visual events far apart in space and time must be integrated into a unified percept. While spatial properties of invisible signals are known to be encoded without awareness, the fate of temporal properties remains largely unknown. Here, we probed temporal integration for two distinct motion stimuli that were either visible or rendered invisible using continuous flash suppression. We found that when invisible, both the direction of apparent motion and the gender of point-light walkers were processed only when defined across short time periods (i.e., respectively 100 ms and 1000 ms). This limitation was not observed under full visibility. These similar findings at two different hierarchical levels of processing suggest that temporal integration windows shrink in the absence of perceptual awareness. We discuss this phenomenon as a key prediction of the global neuronal workspace and the information integration theories of consciousness. 相似文献

ABSTRACTCrying is a common response to emotional distress that elicits support from the environment. People may regulate another’s crying in several ways, such as by providing socio-affective support (e.g. comforting) or cognitive support (e.g. reappraisal), or by trying to emotionally disengage the other by suppression or distraction. We examined whether people adapt their interpersonal emotion regulation strategies to the situational context, by manipulating the regulatory demand of the situation in which someone is crying. Participants watched a video of a crying man and provided support by recording a video message. We hypothesised that when immediate down-regulation was required (i.e. high regulatory demand), participants would provide lower levels of socio-affective and cognitive support, and instead distract the crying person or encourage them to suppress their emotions, compared to when there is no such urgency (i.e. low regulatory demand). As predicted, both self-reported and behavioural responses indicated that high (as compared to low) regulatory demand led to a reduction in socio-affective support provision, and a strong increase in suppression and distraction. Cognitive support provision, however, was unaffected by regulatory demand. When the context required more immediate down-regulation, participants thus employed more regulation strategies aimed at disengaging from the emotional experience. This study provides a first step in showing that people take the context into account when attempting to regulate others’ emotions. 相似文献

Disruption of ongoing appetitive behavior before and after daily avoidance sessions was examined. After baselines of appetitive responding were established under a fixed-interval 180-s schedule of food presentation, 4 rats were exposed to 40-min sessions of the appetitive schedule just prior to 100-min sessions of electric shock postponement, while another 4 rats received the 40-min appetitive sessions just following daily sessions of shock postponement. In all 8 subjects, fixed-interval response rates decreased relative to baseline levels, the effect being somewhat more pronounced when the avoidance sessions immediately followed. The disruption of fixed-interval responding was only partially reversed when avoidance sessions were discontinued. During the initial exposure to the avoidance sessions, patterns of responding under the fixed-interval schedule were differentially sensitive to disruption, with high baseline response rates generally more disturbed than low rates. These disruptions were not systematically related to changes in reinforcement frequency, which remained fairly high and invariant across all conditions of the experiment; they were also not systematically related to the response rates or to the shock rates of the adjacent avoidance sessions. The results, while qualitatively resembling patterns of conditioned suppression as typically studied, occurred on a greatly expanded time scale. As disruption of behavior extending over time, the present data suggest that some forms of conditioned suppression are perhaps best viewed within a larger temporal context. 相似文献

Rat AA-26, despite 1950s "state of the art," nonetheless generated the first set of behavioral pharmacology cumulative records to appear in the weekly journal Science, the century-old publication of the American Association for the Advancement of Science. The laboratory exploits of this dedicated animal called early attention to the methodological fruits of a marriage between pharmacology and the experimental analysis of behavior. 相似文献
