高绩效要求与亲组织不道德行为:基于社会认知理论的视角

通过确立较高的绩效目标以提升组织绩效被普遍认为是一项有效的管理措施。然而,学术界对它的负面影响却缺乏研究。本文提出了高绩效要求将启动员工道德推脱机制为其随后进行的亲组织不道德行为开脱,即道德推脱在高绩效要求与亲组织不道德行为之间起到了中介作用。为了检验这一观点,本研究提出两种不同效应的调节变量:感知的市场竞争正向调节变量之间的间接关系,而道德认同则负向调节这一间接关系。通过对某零售企业225名员工的两阶段调查,本研究提出的调节-中介模型获得了观察数据的支持。本研究的发现有利于进一步了解亲组织不道德行为发生的中介心理机制和边界条件,指导管理者采取恰当的管理措施,以期有效地管控亲组织不道德行为的出现。     

提取引起的遗忘的认知机制

提取引起的遗忘(RIF)指提取某个信息导致对其它相关信息的遗忘,揭示其内在机制是记忆和遗忘领域的一个重要的研究课题。近20年来,各路研究者分别从干扰理论、抑制理论或情境依赖说出发,试图找到引发RIF的唯一的认知机制。基于对有关RIF的认知机制的实证研究的系统分析,可以发现三个理论均有一定的支持证据,因此导致RIF的原因可能包括抑制、干扰和情境的改变等三个方面。今后该领域可结合多种技术手段对这一多元论观点进行直接的检验。     

Inhibitory priming effects in auditory word recognition: when the target's competitors conflict with the prime word

Several studies indicate that the number of similar sounding words that are activated during recognition is a powerful predictor of performance on auditory targets. Words with few competitors are processed more quickly and accurately than words with many competitors. In the present study, we examined the contribution of the competitor set size in determining the magnitude of the inhibitory priming effect. The data show that the priming effect is stronger when word targets have few competitors. This result supports the view of direct competition between lexical candidates.     

Sensitivity to local sentence context information in lexical ambiguity resolution: evidence from left- and right-hemisphere-damaged individuals

Using a cross-modal semantic priming paradigm, the present study investigated the ability of left-hemisphere-damaged (LHD) nonfluent aphasic, right-hemisphere-damaged (RHD) and non-brain-damaged (NBD) control subjects to use local sentence context information to resolve lexically ambiguous words. Critical sentences were manipulated such that they were either unbiased, or biased toward one of two meanings of sentence-final equibiased ambiguous words. Sentence primes were presented auditorily, followed after a short (0 ms) or long (750 ms) interstimulus interval (ISI) by the presentation of a first- or second-meaning related visual target, on which subjects made a lexical decision. At the short ISI, neither patient group appeared to be influenced by context, in sharp contrast to the performance of the NBD control subjects. LHD nonfluent aphasic subjects activated both meanings of ambiguous words regardless of context, whereas RHD subjects activated only the first meaning in unbiased and second-meaning biased contexts. At the long ISI, LHD nonfluent aphasic subjects failed to show evidence of activation of either meaning, while RHD individuals activated first meanings in unbiased contexts and contextually appropriate meanings in second-meaning biased contexts. These findings suggest that both left (LH) and right hemisphere (RH) damage lead to deficits in using local contextual information to complete the process of ambiguity resolution. LH damage seems to spare initial access to word meanings, but initially impairs the ability to use context and results in a faster than normal decay of lexical activation. RH damage appears to initially disrupt access to context, resulting in an over-reliance on frequency in the activation of ambiguous word meanings.     

On the role of preference in response competition

A duration-based preference assessment identified items that matched and did not match the sensory consequences hypothesized to maintain stereotypy. When evaluated in treatment, these items effectively competed with the occurrence of stereotypy, regardless of their sensory properties. It is suggested that relative preference, as measured in duration-based assessment, can be as significant as type of stimulation produced in interventions that reduce automatically reinforced problem behavior.     

Disjunctive Quantum Logic in Dynamic Perspective

In Coecke (2002) we proposed the intuitionistic or disjunctive representation of quantum logic, i.e., a representation of the property lattice of physical systems as a complete Heyting algebra of logical propositions on these properties, where this complete Heyting algebra goes equipped with an additional operation, the operational resolution, which identifies the properties within the logic of propositions. This representation has an important application towards dynamic quantum logic, namely in describing the temporal indeterministic propagation of actual properties of physical systems. This paper can as such by conceived as an addendum to Quantum Logic in Intuitionistic Perspective that discusses spin-off and thus provides an additional motivation. We derive a quantaloidal semantics for dynamic disjunctive quantum logic and illustrate it for the particular case of a perfect (quantum) measurement.     

Attentional control in the aging brain: insights from an fMRI study of the stroop task

Several recent studies of aging and cognition have attributed decreases in the efficiency of working memory processes to possible declines in attentional control, the mechanism(s) by which the brain attempts to limit its processing to that of task-relevant information. Here we used fMRI measures of neural activity during performance of the color-word Stroop task to compare the neural substrates of attentional control in younger (ages: 21-27 years old) and older participants (ages: 60-75 years old) during conditions of both increased competition (incongruent and congruent neutral) and increased conflict (incongruent and congruent neutral). We found evidence of age-related decreases in the responsiveness of structures thought to support attentional control (e.g., dorsolateral prefrontal and parietal cortices), suggesting possible impairments in the implementation of attentional control in older participants. Consistent with this notion, older participants exhibited more extensive activation of ventral visual processing regions (i.e., temporal cortex) and anterior inferior prefrontal cortices, reflecting a decreased ability to inhibit the processing of task-irrelevant information. Also, the anterior cingulate cortex, a region involved in evaluatory processes at the level of response (e.g., detecting potential for error), showed age-related increases in its sensitivity to the presence of competing color information. These findings are discussed in terms of newly emerging models of attentional control in the human brain.     

Partners' internal stress and well-being: The role of dyadic coping and problem resolution

Couples' experiences of daily stress can be detrimental for partners' individual and relational well-being, specifically their identity as a couple, their relational satisfaction, and their life satisfaction. Grounded in the Systemic Transactional Model, this study aimed at analyzing factors that may safeguard partners and their relationship from detrimental effects of internal stress (i.e., stress that originates inside the relationship). We examined the buffering effect of partners' positive dyadic coping and internal problem resolution. Daily diary data were collected across 7 days from 82 heterosexual couples. Multilevel dyadic analyses showed that internal stress was negatively associated with partners' individual and relational well-being. Positive dyadic coping moderated the association between partners' internal stress and couple satisfaction for both partners, but not life satisfaction and couple identity. Moreover, for partners who reported a resolution to the internal problem, the negative associations of internal stress with life satisfaction, couple satisfaction, and couple identity were significantly lower than for those who did not resolve the internal problem. This study confirms the negative role of internal stress on well-being, shows the associations between internal stress and couple identity, and highlights the protective role of dyadic coping and internal problem resolution in couples' daily lives.     

Who lives,who dies,who decides: Differences between mass public shooters who survive,are killed,and commit suicide

This study provides an in-depth analysis of American mass public shooting conclusions between 1966 and 2017. Specifically, this work examines differences in factors contributing to the perpetrator's likelihood of surviving, being killed, and committing suicide. Ten hypotheses, rooted in previous homicide, suicide, homicide-suicide, and mass public shooting literature consider different psychological, situational, and background factors shaping the outcome of mass public shootings. Significant findings indicate factors influencing perpetrators' suicide include suicidal ideation, higher victim counts, and suicide copycat effects. Factors influencing perpetrators being killed similarly include higher victim counts, the arrival of law enforcement, lethal/non-lethal resistance, and government targets. This investigation provides practical implications for practitioners and policymakers, especially law enforcement and mental health practitioners, seeking to develop intervention and prevention strategies for addressing suicidal ideation and its most lethal outcome: mass public shootings.     

How do supporters perceive positive and negative psychological momentum changes during a simulated cycling competition?

ObjectiveThe present study examined changes in sport supporters' psychological momentum (PM) during a simulated cycling competition through the lens of the dynamical systems approach.DesignParticipants were asked to support one of two competing cyclists involved in a race that was displayed on a screen in a lecture hall.MethodThe race scenario was manipulated so that the image of the supported cyclist underwent either positive or negative momentum. At regular intervals, participants indicated their PM perceptions during the race.ResultsPM perceptions rapidly changed at the onset of both the positive and negative momentum sequences and then remained stable, reflecting negative hysteresis. Supporters tended to anticipate the future performance of a given athlete on the basis of their current performance. Moreover, this anticipatory tendency was stronger during the positive momentum sequence than during the negative momentum sequence.ConclusionThese results provide initial insights into how PM perceptions of sport supporters change during a competition.
