The authors conducted 4 experiments to test whether hemispheric lateralization occurs for the processing of geometric word–shape combinations. In 3 experiments, participants responded to geometric shapes combined with geometric words (square, circle, triangle). In the 4th experiment, stimuli were combinations of geometric shapes and nongeometric words. The authors predicted that it would take longer to respond in incongruent conditions (e.g., the word “square” combined with the shape of a circle) than in congruent conditions. The authors found the strongest incongruency effects for the dominant hemisphere—that is, the left hemisphere for responding to words and the right hemisphere for responding to shapes. A Shape Interfering Properties hypothesis (SIP) is a possible explanation for these results. 相似文献

ABSTRACT. The shape bias is an attentional preference children show for the shape of an object over other aspects of the object in a word-learning context. This bias, which aids in establishing a word-object pairing, was investigated in 12-, 18-, and 24-month-old children (n = 90) across noun, adjective, and no-label conditions. The present research presents evidence of development across this time span; there was a transition from a label reducing the chance of shape extensions to indiscriminate shape extensions to a label increasing the chance of shape extensions. This research supports the notion that children are focusing their extensions more toward shape during the course of development thereby developing a more mature and more specialized shape bias. 相似文献

The authors modeled the center of gravity vertical projection (CGV) and the difference, CP - CGV, which, combined, constitute the center of pressure (CP) trajectory, as fractional Brownian motion in order to investigate their relative contributions and t heir spatiotemporal articulation. The results demonstrated that CGV and CP - CGV motions are both endowed in complementary tashion with strong stochastic and part-deterministic behaviors. In addition, if the temporal coordinates remain similar for all 3 trajectories by definition, the switch between the successive control mechanisms appears for shorter displacements for CP - CGV and CGV than for CP trajectories. Results deduced from both input (CG,) and muscular stiffness (CP - CGV) thus provide insight into the way the central nervous system regulates stance control and in particular how CG and CP - CG are controlled. 相似文献

ABSTRACT. The purpose of this study was to clarify the age-related effects of distances from the center of pressure (COP) to the center of mass (COM) (COP-COM distances) during one-leg standing (OLS) task. Healthy old and young adults (n = 11 each) participated in this study. The authors divided the task into 3 phases (accelerated, decelerated, and steady) based on the relationship between COM and COP. COP-COM distances in the older group were significantly reduced during the accelerated phase, then significantly increased during the decelerated and steady phases. Furthermore, distances during these phases correlated inversely with OLS time. The authors conclude that OLS time is shortened by the larger braking response to COM shifts just after leg-lifting, and the production of larger inertial forces to maintain COM position during the OLS in older individuals. 相似文献

This research investigated whether the perceived ability to deceive (PATD) scale predicts ability to deceive in a vocational testing context. Using a quasi-experimental design, participants (N = 85 student and community members) completed the PATD scale and a personality measure under standard instructions before being asked to fake the personality measure as if they were applying for a job in the police force. Based on extant research, successful faking was operationalised as elevated scores on conscientiousness and extraversion and reduced scores on neuroticism. Analysis via independent t-test did not support the hypothesis that PATD predicts faking success. Future research should consider the relationship between PATD and intention to fake, as well as extend examination of PATD to other deception-related contexts. 相似文献

The distressed (Type D) personality (the combination of negative affectivity and social inhibition traits) has been associated with adverse health outcomes. This study investigated the validity of the Type D construct against the Five-Factor Model (FFM) of personality, and its association with emotional control and distress. In total 498 university students (mean age 28.9 ± 8.4 years) completed the Type D scale (DS14), and measurements for the FFM of personality, emotional control, anxiety, depression and stress. The construct validity of the Icelandic DS14 was confirmed. The Type D components negative affectivity and social inhibition were strongly associated with neuroticism and extraversion of the FFM (r = 0.82 and r = −0.67, respectively). Negative affectivity also correlated with rehearsal/rumination (r = 0.58) and social inhibition with emotional inhibition (r = 0.54), indicative of emotional control. Type D personality (40% of sample) was associated with higher levels of anxiety, depression and stress. The Type D personality components were associated with the FFM of personality, emotional control and emotional distress. Importantly, social and emotional inhibition were closely related, providing novel information about the presence of emotional inhibition within the social inhibition trait. 相似文献

Feeling lonely motivates people to reconnect with others, but it can also trigger a vicious cycle of cognitions and behaviours that reinforces their loneliness. In this study, we examined the behavioural consequences of loneliness in a virtual social environment. A total of 176 participants navigated a character (protagonist) through a two-dimensional browser game and rated the character's loneliness multiple times during the game. In the first part of the game, another character is introduced as the protagonist's spouse. At one point, the spouse leaves for an undetermined period of time but later returns. Immediately before this separation, higher ascribed loneliness of the protagonist was associated with more frequent interactions with the spouse. After the reunion, however, higher ascribed loneliness was associated with less frequent interactions with the spouse. Ascribed loneliness was not significantly related to the frequency of interactions with others nor to the frequency of solitary activities. These patterns held after controlling for ascribed positive affect. Participants' levels of loneliness were related to the level of ascribed loneliness only when the spouse was present but not when the spouse was absent. In sum, these findings suggest that the conditions that trigger the vicious cycle of loneliness are person- and situation-specific. 相似文献

The present research examined the degree to which perceptions of emotional utility are stable across contexts and over time. Self-reported perceptions of emotional utility and actual experience of emotion were measured in two samples of college students. In Study 1, participants were presented with two different types of goals (independent vs. interdependent) and were asked to rate the degree to which they found different types of emotions (e.g., appreciation, pride) useful in each context. In Study 2, participants completed daily online questionnaires in which they responded to questions assessing perceptions of emotional utility and actual affect in relation to personal goals. As predicted, across both samples, perceived utility of specific types of emotions was found to be associated with specific types of goals. Importantly, perceived utility of emotion was also found to be a relatively stable individual difference variable, even after taking into account the actual experience of emotion. 相似文献

We examine the association between neighborhood socio-economic disadvantage and perceived stress during middle and late adolescence among African American youth (N = 665; 51 % female; M = 15.9 years at baseline). In addition, we explored the ways through which neighborhood stressors interacted with an individual’s intra- and interpersonal resources (e.g., coping, social support and substance use), to affect their perceived stress trajectories during adolescence. First, we tested a neighborhood stressors model and found that youth who lived in neighborhoods with greater socioeconomic disadvantage had higher baseline stress and a steeper increase in stress over time. When we included individual-level risk and promotive factors in the model, however, the effect of neighborhood disadvantage on perceived stress was no longer significant, and the stress trajectory was explained by adolescent substance use, social support and perceptions of the neighborhood. Our results support theories of stress and coping, and the importance of proximal intra- and interpersonal factors in either amplifying or mitigating perceptions of stress. We discuss implications of the neighborhood context and how our findings may inform future prevention and intervention related to adolescent stress and development. 相似文献

Although the role of exercise in improving mood is well established, less is known about moderators of this effect, particularly outside of the laboratory. The current study examined the effect of gender, type of exercise, level of exertion, and duration of workout on the exercise–mood relationship in a naturalistic setting. One hundred and thirty five participants (64 females) either engaged in weight training (n = 52) or cardiovascular (n = 83) exercise. Pre- and post-exercise assessments of mood were collected and changes in two types of mood, negative mood and exhaustion, were examined. Overall, participants reported improved mood after exercise in both domains. Workout duration and level of exertion significantly moderated the relationship of exercise to mood improvement (i.e., an increase in either corresponded to greater improved mood, ps<0.05). Overall, women showed more improved mood than men in the domain of exhaustion (p = 0.001). 相似文献
