Motor timing and the preparation for sequential actions

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.     

The emotional geographies of neoliberal school reforms: Spaces of refuge and containment

This paper draws from a larger research project about the post high school transitions of young people who were at school during New Zealand’s neoliberal reforms. Our participants included a group of four young men excluded from school and redirected to an Alternative Education programme. Their accounts of their experiences at school differed starkly from what they said about their Alternative Education programme. The emotional content of their accounts reveals how the social and material practices of these respective education sites are constituted differently. Alternative Education operated as a space of refuge from alienation experienced in mainstream schooling as well as a site of containment, separating Alternative Education students from their mainstream peers. Focusing on the emotional geography of one Alternative Education programme offers insight into the emotional geographies of mainstream schooling and, more broadly, of neoliberal education reforms. Drawing on ideas from Massey and Bondi, we demonstrate how alienation is produced and manifested on different scales: teacher–student interactions, school exclusions and policies establishing Alternative Education. The Alternative Education programme discussed here provides a barometer of the broader emotional geographies of New Zealand’s neoliberal education reforms.     

Peer and school problems in the lives of urban adolescents: Frequency, difficulty, and relation to adjustment

This study examined the occurrence of problem situations in the peer and school domains and their relation to adjustment among urban adolescents. Students from three urban middle schools (N = 176) serving a predominantly African American population rated 61 problem situations identified in a previous qualitative study and completed measures of adjustment. Ratings of frequency and difficulty confirmed the relevance of these situations for this population. Confirmatory factor analyses suggested that covariation in the frequency and difficulty of problem situations could be represented by separate factors representing peer situations involving friends, other peer situations, and school situations. The number of different problem situations experienced was significantly correlated with physical and relational aggression, delinquency, depression, anxiety, and self-worth. Several of these relations were strongest for peer situations that did not involve friends. There were few gender differences in the strength of these relations.     

Peer assessments of normative and individual teacher–student support predict social acceptance and engagement among low-achieving children

This study used hierarchical linear modeling to predict first grade students' peer acceptance, classroom engagement, and sense of school belonging from measures of normative classroom teacher–student support and individual teacher–student support. Participants were 509 (54.4% male) ethnically diverse, first grade children attending one of three Texas School districts (1 urban, 2 small city) who scored below their school district median on a measure of literacy administered at the beginning of first grade. Peer nominations from 5147 classmates were used to assess both normative and individual levels of teacher support. Normative classroom teacher–student support predicted children's peer acceptance and classroom engagement, above the effects of child gender, ethnic minority status, and individual teacher–student support. Results are discussed in terms of implications for teacher preparation and professional development.     

对于中国古典道家"自我"的一种新的解读

中国古典道家中并没有“自我”这一概念,但却拥有丰富的关于“自我”的思想。该文在对照西方传统自我观念的基础上,理解中国古典道家的“自我”。指出道家的自我是一种无知的自我、无为的自我、无欲的自我;是一种顺应的自我;是一种幽默化的自我。希望这种解读在某种意义上能够丰富与发展“自我”的概念,并为心理学对于当代中国人“自我”的研究提供些许借鉴。     

An Ecological View of School Satisfaction in Adolescence: Linkages Between Social Support and Behavior Problems

This study investigated the relationships among school satisfaction, social support, and problem behaviors in adolescents. Modest associations were found between school satisfaction and the demographic variables of gender, race, age, and grade level. Support from teachers, parents, and classmates contributed unique variance to ratings of school satisfaction; with teacher support contributing the most unique variance. School satisfaction mediated the relationship between social support and internalizing and externalizing behaviors. School satisfaction did not moderate the relationship between social support and problem behavior; however, it did serve as a protective factor across all levels of social support. Implications are discussed, including suggestions for developing interventions that focus on increasing support for adolescents in efforts to improve school satisfaction and reduce problem behaviors.

Relationships between job evaluation ratings and self-ratings of job characteristics

Self-ratings by 308 shop workers of their job variety, autonomy, task identity, and skill challenge correlate significantly with ratings by observers of the jobs' skill requirements. Self-ratings, however, are unrelated to observers' estimates of the physical demands of the jobs or to environmental conditions of the work. The self-ratings and observer measures provide complementary, not substitute, information. Self-ratings can signal person-job dysfunctions, and more objective job measures can identify possible sources of the dysfunctions. Modifications to job characteristics measures are discussed and suggestions are made to begin a new phase of programmatic job characteristics research.     

Research note: The accuracy of group majorities for disjunctive and conjunctive decision tasks

For complex group decision tasks which can be described in terms of establishing the truth value of conjunctive (and) or disjunctive (or) composite propositions, the advantage for group judgmental accuracy of disaggregating the decision task into separate individual evaluations of the truth value of each component atomic proposition in the composite is investigated. For true propositions it is shown that disaggregation is preferable for conjunctive tasks, but not for disjunctive tasks; while the reverse is true for false propositions.     

The development of basic mechanisms of pattern vision: spatial frequency channels

The mature visual system possesses mechanisms that analyze visual inputs into bands of spatial frequency. This analysis appears to be important to several visual capabilities. We have investigated the development of these spatial-frequency channels in young infants. Experiment 1 used a masking paradigm to test 6-week-olds, 12-week-olds, and adults. The detectability of sine wave gratings of different spatial frequencies was measured in the presence and the absence of a narrowband noise masker. The 12-week data showed that at least two spatial-frequency channels with adultlike specificity are present at 12 weeks. The 6-week data did not reveal the presence of narrowband spatial-frequency channels. Experiment 2 used a different paradigm to investigate the same issue. The detectability of gratings composed of two sine wave components was measured in 6-week-olds and adults. The results were entirely consistent with those of experiment 1. The 12-week and adult data indicated the presence of narrowband spatial-frequency channels. The 6-week data did not. The results of these experiments suggest that the manner in which pattern information is processed changes fundamentally between 6 and 12 weeks of age.
