Predictors of smoking cessation in Taiwan: using the theory of planned behavior

This study aimed to explore the factors predicting the intention to quit smoking and the subsequent behavior 6 months later using the theory of planned behavior (TPB). Data were obtained from 145 smokers who attended a smoking cessation clinic in a community hospital. All participants completed a questionnaire which included demographic information, TPB-based items, perceived susceptibility and previous attempts to quit. The actual quitting behavior was obtained by follow-up phone calls 6 months later. The TPB constructs explained 34% of the variance in intention to quit smoking. By adding perceived susceptibility, the explained variance was significantly improved to 40%. The most important predictors were perceived behavior control and perceived susceptibility, followed by attitude. Subjective norm did not contribute to the prediction of intention. Attitude and perceived behavior control contributed to the prediction of actual quitting behavior, but intention, subjective norm and perceived susceptibility did not. Our findings support that the TPB is generally a useful framework to predict the intention to quit smoking in Taiwan. The inclusion of perceived susceptibility improved the prediction of intention. With regards to successfully quitting, attitude and perceived behavior control played more crucial roles than other TPB constructs. Smoking cessation promotion initiatives focusing on reinforcing cessation belief, enhancing a smoker’s perception of their capability to quit smoking, and persuading smokers that they can overcome cessation barriers to cessation could make subsequent interventions more effective.     

Young children discover how to deceive in 10 days: a microgenetic study

We investigated how the ability to deceive emerges in early childhood among a sample of young preschoolers (Mean age = 34.7 months). We did this via a 10‐session microgenetic method that took place over a 10‐day period. In each session, children played a zero‐sum game against an adult to win treats. In the game, children hid the treats and had opportunities (10 trials) to win them by providing deceptive information about their whereabouts to the adult. Although children initially showed little or no ability to deceive, most spontaneously discovered deception and systematically used it to win the game by the tenth day. Both theory of mind and executive function skills were predictive of relatively faster patterns of discovery. These results are the first to provide evidence for the importance of cognitive skills and social experience in the discovery of deception over time in early childhood.     

中文阅读中基于字和词的跳读与返回抑制:来自眼动方面的证据

该研究通过记录读者自然阅读中的眼动过程,对比考察了中文阅读中基于字和词的跳读与返回抑制事件。结果发现:(1)跳读事件并不影响眼跳前注视的持续时间,说明阅读过程中的眼跳计划被同时制定;(2)在一定范围内,眼跳幅度越大,跳读后注视的持续时间越长,这反映了基本的预视效应;(3)中文阅读中存在返回抑制现象,但这个现象产生的基本依据是低级的空间线索,而非词汇语义单元。     

中文阅读中的认知滞后效应

该研究应用EyelinkⅡ眼动仪,采用眼动随动显示技术操纵注视点左侧文本被掩蔽词汇的范围,考察中文阅读过程中词汇加工的认知滞后效应。结果发现:掩蔽词n以左的文本可严重影响被试的总阅读时间;掩蔽词n-1以左文本则不影响被试的总阅读时间。结果表明,相对于注视位置,中文阅读的认知过程存在明显的滞后效应。     

解释水平在社会距离影响具身模拟中的中介效应检验

具身认知理论及相关的脑研究显示,个体在推断他人心理时具身模拟的强度可能会受到社会距离的影响。基于解释水平理论和具身认知理论,通过两项实验室实验探讨社会距离的外部线索—人格相似性和内外群关系对具身模拟强度的影响。结果显示:社会距离越近,个体的解释水平越低,具身模拟强度越高;解释水平可以部分中介人格相似性对具身模拟的影响,中介效应占总效应量的38.4%;解释水平可以完全中介内外群线索对具身模拟的影响。最后,结合实验结果讨论了个体推断他人心理的过程和机制。     

Working memory can enhance unconscious visual perception

We demonstrate that unconscious processing of a stimulus property can be enhanced when there is a match between the contents of working memory and the stimulus presented in the visual field. Participants first held a cue (a colored circle) in working memory and then searched for a brief masked target shape presented simultaneously with a distractor shape. When participants reported having no awareness of the target shape at all, search performance was more accurate in the valid condition, where the target matched the cue in color, than in the neutral condition, where the target mismatched the cue. This effect cannot be attributed to bottom-up perceptual priming from the presentation of a memory cue, because unconscious perception was not enhanced when the cue was merely perceptually identified but not actively held in working memory. These findings suggest that reentrant feedback from the contents of working memory modulates unconscious visual perception.     

The relationship between mean square differences and standard error of measurement: comment on Barchard (2012)

In the discussion of mean square difference (MSD) and standard error of measurement (SEM), Barchard (2012) concluded that the MSD between 2 sets of test scores is greater than 2(SEM)2 and SEM underestimates the score difference between 2 tests when the 2 tests are not parallel. This conclusion has limitations for 2 reasons. First, strictly speaking, MSD should not be compared to SEM because they measure different things, have different assumptions, and capture different sources of errors. Second, the related proof and conclusions in Barchard hold only under the assumptions of equal reliabilities, homogeneous variances, and independent measurement errors. To address the limitations, we propose that MSD should be compared to the standard error of measurement of difference scores (SEMx-y) so that the comparison can be extended to the conditions when 2 tests have unequal reliabilities and score variances.     

Impact of value congruence on work-family conflicts: the mediating role of work-related support

Based on past research regarding the relationship between person-environment fit and work-family conflict (WFC), we examined the mediating effects of perceived organization/supervisor support on the relationship between person-organization/supervisor value congruence and WFC. A structural equation model was used to test three hypotheses using data collected from 637 workers in Taiwan. Person-organization value congruence regarding role boundaries was found to be positively correlated with employee perception of organizational support, resulting in reduced WFC. Person-supervisor value congruence regarding role boundaries also increased employee perception of organizational support, mediated by perceived supervisor support. Research and managerial implications are discussed.     

Working memory biasing of visual perception without awareness

Previous research has demonstrated that the contents of visual working memory can bias visual processing in favor of matching stimuli in the scene. However, the extent to which such top-down, memory-driven biasing of visual perception is contingent on conscious awareness remains unknown. Here we showed that conscious awareness of critical visual cues is dispensable for working memory to bias perceptual selection mechanisms. Using the procedure of continuous flash suppression, we demonstrated that “unseen” visual stimuli during interocular suppression can gain preferential access to awareness if they match the contents of visual working memory. Strikingly, the very same effect occurred even when the visual cue to be held in memory was rendered nonconscious by masking. Control experiments ruled out the alternative accounts of repetition priming and different detection criteria. We conclude that working memory biases of visual perception can operate in the absence of conscious awareness.
