Relation of person-environment fit to career certainty

This study examined the person-environment fit-career outcome relation by observing interests, self-efficacy and parental support as person aspects and major and occupational choice as separate indicators of the environment. Career certainty was selected as a career outcome. Two dimensional fit indices (People-Things and Data-Ideas) were examined as was the incremental validity of adding prestige fit indices. In addition, we examined the moderation of these PE fit-outcome relations by ethnicity (Anglos vs. Latino/a’s). Results revealed that the PE fit predictors were moderately related and none of the two dimensional PE fit predictors significantly related to career certainty, while nearly all of the Prestige PE fit-certainty relations were significant. Support was found for the spherical structure of work types and person variables [Tracey, T. J. G., & Rounds, J. (1996b). Contributions of the spherical representation of vocational interests.

领导–下属心理资本一致性对周边绩效的影响——工作关系与私人关系的中介作用

本文基于相似吸引理论,考察了领导–下属心理资本一致性能否影响双方的工作关系(领导–下属交换,LMX)和私人关系(领导–下属关系,SSG),继而塑造下属的周边绩效。采用多项式回归和响应面分析技术,对164份领导–下属配对数据进行分析,结果表明：领导–下属心理资本越一致,双方的LMX和SSG越高;在一致情形下,与“低–低一致”相比,”高–高一致”时的LMX和SSG更高。领导–下属心理资本一致性通过LMX、SSG影响下属的周边绩效。以上结果能为如何有效利用心理资本管理领导–下属的人际互动、下属周边绩效提供启发。

The interest-major congruence and college success relation: A longitudinal study

The relation of interest-major congruence to indicators of college success was examined in an initial sample of 80, 574 individuals enrolled in 87 colleges. Both college achievement (GPA after 1 year, after 2 years and at graduation) as well as persistence (enrollment status after 1 year, after 2 years and graduation after 5 years) were used as criteria of college success. Two different representations of interest-major congruence were examined: Euclidean distance and angular agreement. The incremental validity of these two congruence indices above that of standardized academic skills tests (i.e., ACT scores) was examined for each of the six criteria using mixed level modeling so that institutional differences could be examined. Results indicated that both types of congruence were predictors of each of the GPA criteria regardless of institutional differences. However for the enrollment criteria, the overall level of interest scores was found to moderate the congruence-enrollment relation. Congruence for individuals with low overall interest level but not for individuals with high overall interest levels was predictive of persistence. Findings point to the importance of interest-major congruence in the college outcome process, but also highlight the complexity of the congruence-outcome relation.     

The effect of dopaminergic medication on conflict adaptation in Parkinson's disease

Parkinson's disease (PD) is a neurological disorder associated primarily with motor symptoms such as tremor, slowness of movement, and difficulties with gait and balance. Most patients take dopaminergic medication to improve their motor functions. Previous studies reported indications that such medication can impair higher cognitive functions (cf. dopamine overdose hypothesis). In the present study, we examined the effect of medication status on conflict adaptation. PD patients performed a Stroop task in which we manipulated the proportion of congruent and incongruent items, thereby allowing us to explore conflict adaptation. The use of mouse movements allowed us to examine the action dynamics of conflict adaptation in PD, and their sensitivity to dopaminergic medication. Each patient performed the same task twice: once without making changes to their regular medication regime, and once after overnight withdrawal from their medication. Results showed that medication improved mouse movements and alleviated motor symptoms. Moreover, patients' mouse movements were modulated as a function of the proportion congruency manipulation, revealing conflict adaptation in PD, which was unaffected by medication status. The present study extends earlier work on conflict adaptation in PD where reduced transient (trial-by-trial) conflict adaptation was observed ON compared to OFF medication (Duthoo et al., 2013, Neuropsychology, 27, 556). Our findings suggest that more sustained cognitive control processes may not be sensitive to dopamine overdose effects.     

Influence of bilateral motor behaviors on flexible functioning: an embodied perspective

To examine the influence of bilateral motor behaviors on flexibility performance, two studies were conducted. Previous research has shown that when performing unilateral motor behavior that activates the affective and motivational systems of approach versus avoidance (arm flexion vs. extension), it is the congruence between laterality and motor activation that determines flexibility-rigidity functioning (Cretenet & Dru, 2009). When bilateral motor behaviors were performed, a mechanism of embodiment was revealed. It showed that the flexibility scores were determined by the match between the respective qualities of congruence of each of the unilateral motor behaviors performed. These results bring to light an overall embodied mechanism associated with the compatibility of the cognitive impact(s) of each motor behavior performed.     

The mental representation of integers: an abstract-to-concrete shift in the understanding of mathematical concepts

Mathematics has a level of structure that transcends untutored intuition. What is the cognitive representation of abstract mathematical concepts that makes them meaningful? We consider this question in the context of the integers, which extend the natural numbers with zero and negative numbers. Participants made greater and lesser judgments of pairs of integers. Experiment 1 demonstrated an inverse distance effect: When comparing numbers across the zero boundary, people are faster when the numbers are near together (e.g., −1 vs. 2) than when they are far apart (e.g., −1 vs. 7). This result conflicts with a straightforward symbolic or analog magnitude representation of integers. We therefore propose an analog-x hypothesis: Mastering a new symbol system restructures the existing magnitude representation to encode its unique properties. We instantiate analog-x in a reflection model: The mental negative number line is a reflection of the positive number line. Experiment 2 replicated the inverse distance effect and corroborated the model. Experiment 3 confirmed a developmental prediction: Children, who have yet to restructure their magnitude representation to include negative magnitudes, use rules to compare negative numbers. Taken together, the experiments suggest an abstract-to-concrete shift: Symbolic manipulation can transform an existing magnitude representation so that it incorporates additional perceptual-motor structure, in this case symmetry about a boundary. We conclude with a second symbolic-magnitude model that instantiates analog-x using a feature-based representation, and that begins to explain the restructuring process.     

The relationship between implicit and explicit motives, goal pursuit, and autobiographical memory content during a diary study

This online diary study investigated how motives interact with goal pursuit to predict daily autobiographical experiences. Participants (N = 141) completed measures of implicit and explicit achievement, provided daily memories and reports of their goal pursuit during a 3-week diary period. A stronger implicit achievement motive at the onset of the study was associated with more agentic (and fewer communal) autobiographical content. Goal progress was linked with using more agentic words, while goal attainability was related to using more communal words. Interactions between motives and goal pursuit on autobiographical memory suggests a trade-off: Favorable goal pursuit conditions may prompt people not motivated for achievement to shift their focus from agentic to communal themes, while individuals motivated for achievement maintain their priorities.     

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.
