Family influences on the association between sleep problems and anxiety in a large sample of pre-school aged twins

Research suggests that environmental influences are important on the association between sleep problems and anxiety in children. This study examines family influences on the association between sleep problems and anxiety in 6000+ twin pairs. Parents provided information on their twins’ anxiety and sleep problems at ages 3 and 4 years. The family influences maternal depression, life events, socio-economic status, family illness, and family disorganization, were examined using parent-report. Family disorganization and maternal depression showed the strongest correlations with sleep problems (r = .20, .21, respectively) and with anxiety (r = .24, .28). Subsequent analyses indicated that family disorganization and maternal depression (examined individually) each accounted for approximately 30% of the association between sleep problems and anxiety (r = .18). The remaining association was mainly explained by environmental factors making children in the same family alike and genetic influences. This study specifies family influences that may be important in the association between sleep problems and anxiety and highlights areas of research that may be worth pursuing in order to further understand the childhood association between sleep problems and anxiety.     

为什么到手的金牌会“飞走”：竞赛中 “Choking”现象

“Choking”定义为,习惯的运动执行过程发生衰变的现象。其现象主要发生在比赛的关键时刻,或重大的赛事中。本文概述竞赛中的“Choking”现象及有关的定义,并进一步讨论有关的理论和研究中存在的问题。运动心理学家认为,“Choking”机制与运动焦虑有直接的联系。而社会心理学家认为,“Choking”的机制是,由于运动员有意识地控制运动过程,导致运动技术发生改变。理论上的分歧,使心理学家很难为运动员提出一个行之有效地预防“Choking”的方案。文章认为,当前的“Choking”理论过于简单地解释“Choking”现象,导致了实践中出现的矛盾。在综述这些问题的基础上,文章进一步讨论了一个“Choking”理论的“综合模式”。该理论模式强调多因素原则。在压力条件下,分析“Choking”机制应考虑任务特征和技术水平的因素。文章根据这一理论模式,建议运动员在比赛中,应分析具体情况,选择一个适合的应付压力的策略,是可以减少竞赛中“Choking”现象的。最后,文章建议了3个今后研究的方向。     

Perfectionism, Cognition, and Affect in Response to Performance Failure vs. Success

The current paper describes the results of an experiment in which 200 students who varied in levels of trait perfectionism performed a laboratory task of varying levels of difficulty. Participants received either negative or positive performance feedback, independent of their actual level of performance. Analyses of pre-task and post-task measures of negative and positive affect showed that individuals with high self-oriented perfectionism experienced a general increase in negative affect after performing the task, and self-oriented perfectionists who received negative performance feedback were especially likely to report decreases in positive affect. Additional analyses showed that self-oriented perfectionists who received negative feedback responded with a cognitive orientation characterized by performance dissatisfaction, cognitive rumination, and irrational task importance. In contrast, there were relatively few significant differences involving other-oriented and socially prescribed perfectionism. Collectively, our findings support the view that self-oriented perfectionism is a vulnerability factor involving negative cognitive and affective reactions following failure experiences that reflect poorly on the self.     

The end of the reading age: grade and age effects in early schooling

During the school years, psychological test norms may be indexed by age or by grade. A number of studies have shown that using age-based norms appears to produce biases associated with grade assignment. Cahan and Cohen [Child Dev. 60 (1989) 1239-1249] showed that the effect of one grade was over twice the effect of 1 year of age for most verbal cognitive ability subtests in Grades 4-6. A higher ratio might be expected for more curriculum-related areas such as reading tests. Analysis of a representative sample of 4257 Grade 1 and 2 children in Tasmanian government schools (which use relatively strict age assignment to grades) for three subtests of the Woodcock Reading Mastery Test—Revised (WRMTR): Word Identification, Word Attack, and Passage Comprehension, showed that the grade effect is about twice the age effect. This data shows that using age-based norms instead of grade-based norms for reading and other verbal ability tests may produce bias in the early school years. Psychologists should thus be primarily concerned with children's educational history, as once children have entered school other developmental factors indexed by age have less influence on children's verbal performance.     

Assessing individual differences in achievement motivation with the Implicit Association Test

The authors examined the validity of an Implicit Association Test (Greenwald, McGhee, & Schwartz, 1998) for assessing individual differences in achievement tendencies. Eighty-eight students completed an IAT and explicit self-ratings of achievement orientation, and were then administered a mental concentration test that they performed either in the presence or in the absence of achievement-related feedback. Implicit and explicit measures of achievement orientation were uncorrelated. Under feedback, the IAT uniquely predicted students’ test performance but failed to predict their self-reported task enjoyment. Conversely, explicit self-ratings were unrelated to test performance but uniquely related to subjective accounts of task enjoyment. Without feedback, individual differences in both performance and enjoyment were independent of differences in either of the two achievement orientation measures.     

The Implicit Life Satisfaction Measure

The Implicit Association Test, developed by Greenwald and colleagues in 1998, was adapted to measure satisfaction with life by assessing the strength of automatic associations of My life with Good- versus Bad-related words. A series of studies explored some psychometric as well as methodological properties of the Implicit Life Satisfaction measure (ILS). The ILS demonstrated good internal consistency and moderate temporal stability. Studies revealed that: (i) the type of stimuli used for target and attribute categories influences the magnitude of the ILS effect; (ii) participants could voluntarily suppress their satisfaction with life on the ILS, but not enhance it; and (iii) handedness of categories did not affect the participants' performance on the ILS. Overall, the ILS measures are: (i) independent of traditional life satisfaction self-report measures; and (ii) positive for most people.

The trichotomous achievement goal model and intrinsic motivation: a sequential mediational analysis

This experiment was designed to extend the research by Elliot and Harackiewicz (1996) on the trichotomous achievement goal model in several important ways and to more thoroughly document the processes through which the goals in the trichotomous model influence intrinsic motivation. Results indicated that performance-avoidance goals undermined intrinsic motivation relative to performance-approach and mastery goals; the latter goals evidenced the same intrinsic motivation. These results were obtained using highly evaluative performance goal manipulations, with early adolescent participants, and for a motor task relevant to physical ability. Sequential mediational analyses revealed that competence valuation, state anxiety, and task absorption processes accounted for the observed effects. Perceived competence served neither mediating nor moderating roles.     

Information leakage in the Response Time‐Based Concealed Information Test

The Response Time‐Based Concealed Information Test (RT‐CIT) can reveal when a person recognizes a relevant (probe) item among other, irrelevant items, based on comparatively slow responses to the probe item. For example, if a person is concealing his or her true identity, one can use the suspected identity details as probes, and other, random details as irrelevants. However, in our study, we show that even when participants are merely informed about such probes (i.e., the relevant identity details) before performing the RT‐CIT, their responses will also be slower to these details. Hence, it is more difficult to distinguish such innocent but pre‐informed persons from actually guilty persons. At the same time, we introduce a CIT version with familiarity‐related inducer stimuli, but with no targets, that elicits probe‐minus‐irrelevant RT differences only among guilty participants but not among informed innocent participants. Implications for the theory and the application of CITs are discussed.
