Does work engagement increase person–job fit? The role of job crafting and job insecurity

Drawing on the expanded model of person–environment fit and job crafting theory, this study investigates the underlying processes of the relationship between work engagement and changes in person–job fit. A two-wave longitudinal study was conducted among 246 Chinese employees of a high technology company. As hypothesized, the results show that work engagement is positively related to changes in demands–abilities fit through changes in physical job crafting and positively related to changes in needs–supplies fit through changes in relational job crafting. As predicted, the positive relationship between work engagement and changes in relational job crafting (however, not changes in physical job crafting) is strengthened under conditions of high (vs. low) job insecurity. Our findings indicate that engaged employees craft their work in physical and relational ways, which creates a better person–job fit. The theoretical and practical implications are discussed.     

加压素对记忆巩固过程作用的研究 Ⅱ.GABA在加压素易化记忆巩固过程中作用的探讨

本文探讨了脑内GABA能神经元在加压素易化记忆巩固过程中的作用。结果表明,第三天建立实验后立即腹腔注射印防己毒素(picrotoxin,0.5mg/kg),消除了加压素对条件反应消退过程的延缓作用,而注射氨氧乙酸(aminooxy-acetic acid,20mg/kg)获得相反结果。 实验结果提示,脑内GABA能神经元可能参与了加压素对记忆巩固过程的易化作用。     

Linking metaphor comprehension with analogical reasoning: Evidence from typical development and autism spectrum disorder

We examined the relationship between metaphor comprehension and verbal analogical reasoning in young adults who were either typically developing (TD) or diagnosed with Autism Spectrum Disorder (ASD). The ASD sample was highly educated and high in verbal ability, and closely matched to a subset of TD participants on age, gender, educational background, and verbal ability. Additional TD participants with a broader range of abilities were also tested. Each participant solved sets of verbal analogies and metaphors in verification formats, allowing measurement of both accuracy and reaction times. Measures of individual differences in vocabulary, verbal working memory, and autistic traits were also obtained. Accuracy for both the verbal analogy and the metaphor task was very similar across the ASD and matched TD groups. However, reaction times on both tasks were longer for the ASD group. Additionally, stronger correlations between verbal analogical reasoning and working memory capacity in the ASD group indicated that processing verbal analogies was more effortful for them. In the case of both groups, accuracy on the metaphor and analogy tasks was correlated. A mediation analysis revealed that after controlling for working memory capacity, the inter-task correlation could be accounted for by the mediating variable of vocabulary knowledge, suggesting that the primary common mechanisms linking the two tasks involve language skills.     

On the automaticity of contingent capture: disruption caused by the attentional blink

Converging evidence has shown that onset capture can be completely eliminated by the demands of a concurrent task and during the attentional blink. In the present study, we investigated contingent capture during the attentional blink. We found that contingent capture was attenuated, or even completely eliminated, during the “blink” time of the attentional blink. These results indicate that contingent capture requires limited attentional resources.     

Personality profiling of South African rugby union players

This study aimed to investigate whether differences exist in the personality profiles of professional and semi-professional rugby union players. Participants were 73 male rugby players, 52 professional players and 21 semi-professional players. All participants completed the NEO Five-Factor Personality Inventory (NEO-FFI) as part of the WebNeuro Sport online assessment. An independent sample t-test showed a statistically significant difference in neuroticism between the professional and semi-professional players. The magnitude-based inference method confirmed the results of the independent sample t-test with a moderate effect. The potential practical value of these findings is that the Neuroticism scale of the Big Five personality dimensions can be used as a screening tool for indicating which players a team would want to recruit and invest time and money in since these players will most likely be capable of progressing to the top level in their sport.     

The relative position priming effect depends on whether letters are vowels or consonants

The relative position priming effect is a type of subset priming in which target word recognition is facilitated as a consequence of priming the word with some of its letters, maintaining their relative position (e.g., csn as a prime for casino). Five experiments were conducted to test whether vowel-only and consonant-only subset primes contribute equally to this effect. Experiment 1 revealed that this subset priming effect emerged when primes were composed exclusively of consonants, compared with vowel-only primes (csn-casino vs. aia-animal). Experiment 2 tested the impact of letter frequency in this asymmetry. Subset priming effects were obtained for both high- and low-frequency consonants but not for vowels, which rules out a letter frequency explanation. Experiment 3 tested the role of phonology and its contribution to the priming effects observed, by decreasing the prime duration. The results showed virtually the same effects as in the previous experiments. Finally, Experiments 4 and 5 explored the influence of repeated letters in the primes on the magnitude of the priming effects obtained for consonant and vowel subset primes (iuo-dibujo and aea-madera vs. mgn-imagen and rtr-frutero). Again, the results confirmed the priming asymmetry. We propose that a functional distinction between consonants and vowels, mainly based on the lexical constraints imposed by each of these types of letters, might provide an explanation for the whole set of results.     

预防青少年犯罪的关键：优化家庭功能

家庭在预防青少年犯罪中发挥着学校和社会所无法比拟的优势,这是由家庭所独有的功能决定的。当前在预防青少年犯罪中,应突出和强调家庭的重要地位。从家庭与青少年违法犯罪之间的关系来看,直接影响青少年违法犯罪行为的是家庭的功能缺陷而不是家庭结构的变化,所以,优化家庭功能,是当前预防青少年犯罪的关键,但这不能仅仅期待广大家长的自觉,要想转变传统观念,把法律的触角伸向家庭,必须在法律上做出规定才是切实有效的途径。     

组织结构图标记对文章整体信息理解与保持的影响

本研究采用实验的方法,研究了组织结构图标记对被试文章整体信息理解与保持的影响。结果表明:(1)用组织结构图进行标记能有效提高被试对文章整体信息的通达;(2)组织结构图标记类型与文章难度之间存在显著的交互作用,即在文章容易时,标记效应不显著;在文章较难时,标记效应极显著;(3)当阅读材料较难时,在半标记条件下,被试得分最高;全标记次之;无标记最低。
