Movement duration does not affect automatic online control

Pisella et al. (2000) have shown that fast aiming movements are automatically modified on-line in response to a change in target position. Specifically, when a movement is less than 300 ms in duration the reach is completed to a target’s new location even when one never intended to respond to the target jump. In contrast, when movements are slower, the reach is completed according to instructions. At present, it is unclear if it is possible for one’s intentions to guide the initial stages of these slow movements. To determine if the intentional control mechanism can guide the initial stages of a slow aiming movement, participants aimed to targets that could jump at movement onset, with a slow and very slow movement time goal. In particular, participants were to point towards (“pro-point”) or away from (“anti-point”) the target jump, with a movement time goal of 500 or 1200 ms. Results showed that in the anti-point condition, movement trajectories first deviated in the same direction as the target jump, followed by a response in the intended (opposite) direction. This suggests that while movement outcome is controlled by the intentional system, even in these slow aiming movements the automatic system is engaged at movement onset.     

White–black differences in g and non-g effects for the SAT and ACT

This research examined g and non-g effects for the SAT and ACT for whites and blacks. SAT scores, ACT scores, and college GPAs were obtained from the National Longitudinal Survey of Youth. g was estimated using the Armed Services Vocational Aptitude Battery. Results indicated that (a) the g loadings of SAT and ACT composite scores were lower for whites than blacks, (b) group differences in the g loadings were related to the math subtests of the SAT and ACT, and (c) non-g variance accounted for surprisingly large percentages of SAT–GPA and ACT–GPA relations (range = 37–67%). The findings are discussed in terms of Spearman’s Law of Diminishing Returns.     

Structure of vocational interests in Serbia: Evaluation of the spherical model

To explore the structure of vocational interests in Serbia, 1063 participants of various age, education and gender completed the Serbian version of the Personal Globe Inventory [PGI, Tracey, T. (2002). Personal Globe Inventory: Measurement of the spherical model of interests and competence beliefs. Journal of Vocational Behavior, 6, 113-172]. The fit of Tracey’s octagonal and spherical models to the structure of correlations between Tracey’s eight and 18 type scales was evaluated, as was the fit of Holland’s hexagonal, Gati’s, Rounds-Tracey’s and Liu-Rounds’ models to the structure of correlations between RIASEC scales. Randomization test of hypothetical orders, multidimensional scaling with fixed coordinates and Myors’ test were used to assess the fit of models to the data. The results showed good fit of Tracey’s octagonal and spherical models to the data. Holland’s hexagonal model also fit the data very well, but the fit of Gati’s, Rounds-Tracey’s and Liu-Rounds’ models of relations between RIASEC types was either nonsignificant or very low.     

工作记忆表征捕获眼动中的颜色优先性

刺激属性所具有的引导效力在工作记忆表征自上而下地引导注意捕获过程中起重要作用, 已有研究表明工作记忆表征的颜色属性在引导注意时具有一定的优势。研究采用工作记忆任务与视觉搜索任务相结合的双任务范式, 结合眼动追踪技术, 通过设置具有较强引导效力的颜色属性与朝向属性进行直接竞争的实验条件, 进一步考察工作记忆表征的颜色属性是否依然具有优先性。实验1发现工作记忆表征的颜色属性与朝向属性同时竞争眼动捕获时, 颜色属性表现出较强的优势, 而朝向属性单独呈现时并未表现出任何捕获效应。实验2与3进一步证实了颜色属性捕获眼动的优先性, 即当颜色属性在面临作为靶子属性的朝向属性的竞争时, 依然能捕获更多的注视点。这些结果直接证实了工作记忆表征的颜色属性在工作记忆表征的捕获眼动的过程中具有较强的引导效力, 相对于其他刺激属性(如朝向、形状)更具有优先性。     

Integrating vocational interests, competencies, and interpersonal dispositions in middle school children

Vocational interests and interpersonal dispositions have been well researched in adults from the perspectives of Holland's RIASEC (1997) model of interests and the Interpersonal Circumplex (IPC), respectively. Few studies have applied either model to children and no studies have examined their overlap in children. A vector fitting procedure was applied to data from adults to demonstrate the intersection of vocational interests and interpersonal dispositions from the perspective of the IPC. The same procedure was then applied to interests and competencies and interpersonal dispositions in a sample of sixth grade children. Plotting the vocational variables within interpersonal space defined by the IPC showed the specific interpersonal aspects of vocational interests in young adults and interests and competencies in late childhood. Half of the interests had associations with the IPC that were consistent across adults and children, while the remaining interests had associations that were unique to children.     

Vocational interests across 20 years of adulthood: Stability,change, and the role of work experiences

Vocational interests demonstrate high rank-order stability during childhood and adolescence. However, few studies have investigated the development of vocational interests into adulthood. The present study examined rank-order and profile stability, mean-level and correlated change, and individual differences in change in RIASEC scores across 20 years of adulthood. In addition, life events were examined as moderators of change. Rank-order stability was strong across vocational interest dimensions. Mean-level changes also occurred, with increases in Realistic interests and decreases in Investigative interests for men, increases in Enterprising interests for women, and decreases in Artistic interests for men and women. Individual differences in change indicated that not everyone changed in the same manner, with occupational experiences, such as job loss, related to greater change.     

Associations between procrastination,personality, perfectionism,self-esteem and locus of control

To date, many variables but particularly trait-like psychological constructs have been found to strongly contribute to procrastination but the complex relations among these variables collectively have received almost no attention. The purpose of the study was to provide a more profound understanding of the relations between procrastination, perfectionism, big five personality, locus of control and self-esteem. Young adults (162 women, 80 men: M?=?20.98) completed measures of academic procrastination, self-esteem, big five personality, perfectionism and locus of control. Parental criticism was a significant correlate of procrastination, while personality traits of conscientiousness, agreeableness and organisation were inversely associated with procrastination behaviour. These findings suggest that personality-based intervention approaches with the inclusion of family can be more influential in procrastination prevention and treatment.     

The role of chance events in career decision making

Two studies are reported that investigate the role of chance events as influences in career decision making. In study one, the results of a large-scale survey of high-school and university students (N = 772) investigating influences on their career decision making are presented. Chance events were reported as influencing the career decisions of 69.1% of the sample. In the second study, the role of locus of control was found to be moderately associated with reporting chance events. More External control individuals tend to report more chance events than their Internal control counterparts. Implications for career choice theory and research are discussed.     

Child vocational development: A review and reconsideration

Childhood marks the dawn of human development. To organize, integrate, and advance knowledge about vocational development during this age period from a life-span perspective, we conducted a comprehensive review of the empirical vocational development literature that addresses early-to-late childhood. The review considers career exploration, career awareness, vocational expectations and aspirations, vocational interests, and career maturity/adaptability. By conducting the review, we sought to consolidate knowledge and identify avenues for further research concerned with vocational development in childhood and across the life span. Linking knowledge of child vocational development with what is known about adolescent and adult vocational development and conducting research that embeds vocational development within the fabric of a life-span developmental framework could move the field of vocational psychology from a disjointed perspective on career as studied in isolated age groups and toward an integrated life-span conceptualization.     

Examination of the structure of Irish students’ vocational interests and competence perceptions

A sample of 307 Irish high school students completed a modified version of the Personal Globe Inventory (PGI, Tracey, 2002). Results of separate principal components analyses demonstrated the presence of three substantive factors: People/Things, Data/Ideas, and Prestige, similar to the structure of the PGI in US samples (Tracey, 2002). The fit of Holland’s six-type RIASEC, the PGI eight-type model, and the PGI spherical structure to the data were examined using the randomized test of hypothesized order relations. The results demonstrated that each model fit the Irish data well. No structural differences were found between gender groups. The results support the structural validity of the modified PGI in an Irish context.
