Motor timing is essential for performing self-initiated movement sequences. Here, we investigated how sequence rhythm, or the timing for co-ordinating movements within a sequence, contributes to action preparation, compared with other processes occurring during sequence planning. First, we recorded the readiness potential (RP) in a condition of complex sequence rhythm and in condition of high demand on the timing for sequence initiation. We found that sequence rhythm and sequence initiation are independent processes, with sequence initiation contributing to early RP. Second, we compared the RP recorded in a condition of complex sequence rhythm and in a condition of complex sequence order, in which a complex combination of finger sub-movements had to be correctly ordered within a sequence. We found that sequence rhythm and sequence order share common processes occurring late RP. We suggest that the preparation for movement involves independent processes devoted to different aspects of motor timing and sequencing. 相似文献

To suggest that Daniel Dennett is a deist is to invite ridicule. Dennett is both an avowed atheist and defender of naturalism in philosophy. Yet if we pay heed to the entirety of Dennett’s claims a curious picture emerges. My suggestion is that Hegel and Marx represent the rival responses to what we might call the modern predicament: what is the nature of existence in a world which seems a mechanism? Dennett’s response to this question is Hegelian, and involves a commitment to a religiosity which might surprise those otherwise receptive to his arguments. 相似文献

Perceived racial discrimination, self-control, anger, and either substance use or use cognitions were assessed in 2 studies conducted with samples of African American adolescents. The primary goal was to examine the relation between discrimination and self-control over time; a 2nd goal was to determine whether that relation mediates the link between discrimination and substance use found in previous research. Study 1, which included a latent growth curve analysis with 3 waves of data, indicated that experience with discrimination (from age 10 years to age 18 years) was associated with reduced self-control, which then predicted increased substance use. Additional analyses indicated anger was also a mediator of this discrimination to use relation. Study 2, which was experimental, showed that envisioning an experience involving discrimination was associated with an increase in substance-related responses to double entendre words (e.g., pot, roach) in a word association task, especially for participants who were low in dispositional self-control. The effect was again mediated by reports of anger. Thus, the "double mediation" pattern was discrimination → more anger and reduced self-control → increased substance use and/or substance cognitions. Results are discussed in terms of the long-term impact of discrimination on self-control and health behavior. Implications for interventions aimed at ameliorating the negative effects of discrimination and low self-control on health are also discussed. 相似文献

One of the most dominant approaches to semantics for relevant (and many paraconsistent) logics is the Routley?CMeyer semantics involving a ternary relation on points. To some (many?), this ternary relation has seemed like a technical trick devoid of an intuitively appealing philosophical story that connects it up with conditionality in general. In this paper, we respond to this worry by providing three different philosophical accounts of the ternary relation that correspond to three conceptions of conditionality. We close by briefly discussing a general conception of conditionality that may unify the three given conceptions. 相似文献

School connectedness is central to the long term well-being of adolescents, and high quality parent–child relationships facilitate
school connectedness. This study examined the extent to which family relationship quality is associated with the school connectedness
of pre- and early teenagers, and how this association varies with adolescent involvement in peer drinking networks. The sample
consisted of 7,372 10–14 year olds recruited from 231 schools in 30 Australian communities. Participants completed the Communities that Care youth survey. A multi-level model of school connectedness was used, with a random term for school-level variation. Key independent
variables included family relationship quality, peer drinking networks, and school grade. Control variables included child
gender, sensation seeking, depression, child alcohol use, parent education, and language spoken at home. For grade 6 students,
the association of family relationship quality and school connectedness was lower when peer drinking networks were present,
and this effect was nonsignificant for older (grade 8) students. Post hoc analyses indicated that the effect for family relationship
quality on school connectedness was nonsignificant when adolescents in grade 6 reported that the majority of friends consumed
alcohol. The results point to the importance of family-school partnerships in early intervention and prevention. 相似文献

Mastery motivation is a psychological force that stimulates an individual to attempt to master a task that is challenging to him or her. This prospective longitudinal study examined the relationship between maternal stress, using the Parenting Stress Index-Short Form, and infant mastery motivation, using the Dimensions of Mastery Questionnaire, for 150 mother-infant pairs assessed at both 6- and 18-months of age. Infants of mothers with elevated stress levels at 6 months tended to show lower mastery motivation at 18 months (standardized beta=-.46, p=.001). Conversely, infants with lower general competence (standardized beta=-.24, p=.021) and lower persistence during social interactions with other children (standardized beta=-.18, p=.037) at 6 months of age had mothers with elevated total stress at 18 months of age. Implications for programs which simultaneously intervene with child and mother are discussed. 相似文献

Visual attention has temporal limitations. In the attentional blink (AB) a stream of stimuli such as letters or digits are presented to a participant on a computer monitor at a rapid rate. Embedded in the stream are two targets that the participant must try to identify. Identification of the second target is severely impaired if it is presented within approximately 500ms of the first target. This is the 'blink' in visual attention. In this study we examined the role of the magnocellular visual pathway in the AB. This fast conducting pathway has high temporal resolution and contrast sensitivity. It is also insensitive to the direction of chromatic contrast, and this attribute was exploited in order to isolate its contributions to temporal attention. Colour defined, luminance noise masked AB streams were compared to AB streams of varying achromatic contrast. The four observers, (2F and 2M) aged between 21 and 35years, had normal visual acuity and colour vision. The colour stimuli produced a similar blink to the moderate contrast achromatic stimuli. This indicates that the magnocellular pathway does not have a privileged role in the attentional blink. We provide an explanation of previous apparently contradictory findings in terms of the role of different types of visual masking in the attentional blink. 相似文献

Three studies tested the hypothesis that the relation between perceived racial discrimination and substance use reported in previous research is moderated by use of substances as a coping mechanism. Studies 1 and 2 were experimental studies of African American adolescents' and young adults' reactions to a discrimination experience. Results revealed that those who endorsed substance use-as-coping reported more willingness to use substances after experiencing discrimination. Study 3 was a prospective study of the relation between perceived discrimination and substance use over an 8-year period in African American adolescents. Results demonstrated that discrimination is associated with increases in substance use, but only among adolescents who endorse substance use-as-coping. Together, these three studies provide evidence that experiencing discrimination has both short- and long-term detrimental effects on African Americans' substance use, but significantly more so for those who adopt a pattern of using substances as a coping mechanism.

Although relevant nomothetically-based personality literature has made great advances in recent years correlating traits to measures of procrastination, little is known about the specific irrational beliefs of procrastinators, especially when they are actively avoiding tasks or situations. Based on theories from Rational Emotive Behavior Therapy (REBT), it was hypothesized that compared to non-procrastinators, college student academic procrastinators would show greater self depreciation, greater other depreciation, greater life condition depreciation, and a lower frustration tolerance. Academic procrastination was operationally defined by quartile distributions on two self- report measures and three classroom-based assignments. Procrastinators and non-procrastinating students were given instructions to write approximately 500 words about their thoughts and feelings while they were in the process of actively putting off a specific, real event. While actually procrastinating, students logged on to a web site and made text entries describing what was going through their minds. Data were analyzed with the Psychiatric Content and Diagnosis Program Version 3 (PCAD 3; Gottschalk and Bechtel in Psychiatric content and diagnosis: the PCAD 3. GB Software, Brighton, MI, 2007). Procrastinators and non-procrastinators differed on relevant PCAD scales, supporting the hypotheses derived from REBT theory. Treatment implications and directions for future research are discussed. 相似文献
