以444名青年为研究对象,采用Schutte编制的《情绪智力量表》、艾森克人格问卷和Diener等人编制的《国际大学调查》为研究工具,调查青年各群体的主观幸福感水平,并对情绪智力和主观幸福感的关系进行了研究。结果发现,青年不同群体之间存在显著的主观幸福感差异,本科生群体的主观幸福感水平最高;在控制了人口学变量和人格变量之后,情绪智力能独立预测主观幸福感各维度的变异。  相似文献

Bistable figures provide a fascinating window through which to explore human visual awareness. Here we demonstrate for the first time that the semantic context provided by a background auditory soundtrack (the voice of a young or old female) can modulate an observer's predominant percept while watching the bistable "my wife or my mother-in-law" figure (Experiment 1). The possibility of a response-bias account-that participants simply reported the percept that happened to be congruent with the soundtrack that they were listening to-was excluded in Experiment 2. We further demonstrate that this crossmodal semantic effect was additive with the manipulation of participants' visual fixation (Experiment 3), while it interacted with participants' voluntary attention (Experiment 4). These results indicate that audiovisual semantic congruency constrains the visual processing that gives rise to the conscious perception of bistable visual figures. Crossmodal semantic context therefore provides an important mechanism contributing to the emergence of visual awareness.  相似文献

Different exercise paradigms show differential effects on various forms of memory. We hypothesize that the differential effects of exercises on memory performance are caused by different neuroplasticity changes in relevant brain regions in response to different exercise trainings. We examined the effects of treadmill running (TR) and wheel running (WR) on the Pavlovian fear conditioning task that assesses learning and memory performance associated with the amygdala (cued conditioning) and both the amygdala and hippocampus (contextual conditioning). The skeletal muscle citrate synthase activity, an indicator of aerobic capacity, was elevated in rats received 4 w of TR, but not WR. While both TR and WR elevated the contextual conditional response, only TR facilitated the cued conditional response. Using a single-neuron labeling technique, we found that while both TR and MR enlarged the dendritic field and increased the spine density in hippocampal CA3 neurons, only TR showed these effects in basolateral amygdalar neurons. Moreover, both types of exercise upregulated synaptic proteins (i.e., TrkB and SNAP-25) in the hippocampus; however only TR showed similar effects in the amygdala. Injection of K252a, a TrkB kinase inhibitor, in the dorsal hippocampus or basolateral amygdala abolished the exercise-facilitated contextual or cued fear learning and memory performance, respectively, regardless of the types of exercise. In summary, our results supported that different types of exercise affect the performance of learning and memory via BDNF-TrkB signaling and neuroplasticity in specific brain regions. The brain region-specific neuronal adaptations are possibly induced by various levels of intensity/stress elicited by different types of exercise.  相似文献

Mariners actively adjust their body orientation in response to ship motion. On a ship at sea, we evaluated relations between standing postural activity and the performance of a precision aiming task. Standing participants (experienced mariners) maintained the beam from a handheld laser on a target. Targets were large or small, thereby varying the difficulty of the aiming task. Targets were located in front of the participant or to the participant's right (requiring participants to look over the right shoulder), thereby varying the functional consequences (for the aiming task) of postural activity in different body axes. The torso was oriented toward the bow or toward the ship's side (athwartship), thereby varying the effects on postural activity of differential motion of the ship in its different axes. The weather was rough, producing high magnitudes of ship motion, which sometimes caused participants to step or stagger. Our manipulations influenced the magnitude and dynamics of head and torso movements, as well as the organization of movement in different axes. The results provide the first empirical confirmation that postural activity can be influenced by orientation of the torso relative to a ship. Despite powerful effects of ship motion, postural activity was influenced by variations in target location and in the difficulty of the aiming task, replicating subtle effects that have been observed on land. We discuss implications for hull design and the placement of workstations on ships.  相似文献

Maintaining a satisfying heterosexual relationship is important to many individuals?? happiness and physical health. Evolutionary theories on the formation of relationships suggest that adult attachment and relationship commitment are universal mechanisms for securing and maintaining such mating relationships. This study sought to understand how these two mechanisms may link to each other and how they in turn contribute to relationship satisfaction with one??s current partner in Hong Kong Chinese and American cultures. Similarities in the model for relationship satisfaction were found among young dating couples in the United States and Hong Kong. Specifically, attachment anxiety was positively linked to structural commitment, whereas attachment avoidance was negatively related to personal commitment. Both dimensions of attachment (anxiety and avoidance) and both components of commitment (personal and structural) were found to predict current relationship satisfaction significantly and equivalently across cultures, with the pathway from attachment avoidance to current relationship satisfaction similarly mediated by personal commitment in both cultural groups. These results were interpreted in terms of a probable universal logic informing the interpersonal dynamics involving attachment and relationship commitment.  相似文献

This article compares the use of single- and multiple-item pools with respect to test security against item sharing among some examinees in computerized testing. A simulation study was conducted to make a comparison among different pool designs using the item selection method of maximum item information with the Sympson-Hetter exposure control and content balance. The results from the simulation study indicate that two-pool designs have a better degree of resistance to item sharing than do the single-pool design in terms of measurement precision in ability estimation. This article further characterizes the conditions under which employing a multiple-pool design is better than using a single, whole pool in terms of minimizing the number of compromised items encountered by examinees under a randomized item selection method. Although no current computerized testing program endorses the randomized item selection method, the results derived in this study can shed some light on item pool designs regarding test security for all item selection algorithms, especially those that try to equalize or balance item exposure rates by employing a randomized item selection method locally, such as the a-stratified-with-b-blocking method.  相似文献

Despite the established relationship between social anxiety and attentional bias towards threat, a growing base of evidence suggests that social anxiety is additionally maintained by a deficit in the attentional processing of positive information. However, it remains unclear which component of attention is implicated in this deficit. Using eye movement-based measures and a novel attentional cuing methodology, the present study sought to investigate the presence of anxiety-linked bias in attentional engagement with, attentional disengagement from, and total fixation time to, socially relevant emotional stimuli in individuals diagnosed with social anxiety disorder, relative to non-socially anxious controls. Socially anxious individuals were found to exhibit faster attentional disengagement from positive stimuli, and reduced total fixation time to all emotional stimuli, relative to controls. Additionally for socially anxious individuals, lower total fixation times to positive stimuli were associated with higher levels of state anxiety. No differential pattern of engagement was evident between groups. We conclude that social anxiety is maintained in part by the aberrant processing of positive social stimuli.  相似文献
