Considering self‐interests and symbolism together: How instrumental and value‐expressive motives interact to influence supervisors’ justice behavior 下载免费PDF全文
Drawing upon functional theories of attitudes and the organizational justice literature, the current research suggests that people's attitudes toward justice likely serve an instrumental function (grounded in self‐interest, rewards maximization, and punishment minimization) as well as a value‐expressive function (grounded in the expression of self‐concept and values). Importantly, these two functions co‐exist and interact to influence supervisors’ justice behavior and the consistency of such behavior via supervisors’ justification for unjust behavior. Findings from a set of experimental and correlational studies confirmed these predictions. The positive effects of supervisors’ value‐expressive function on justice behavior and its consistency were stronger when their instrumental function was lower (vs. higher), and justification for unjust behavior mediated these effects. Also, supplementary analyses showed that the consistency of supervisors’ justice behavior positively predicted subordinates’ overall justice perceptions beyond the effects of the overall level of justice behavior. We conclude by discussing the theoretical and practical implications of these findings. 相似文献

Number and Time: Reflections Leading toward the Unification of Depth Psychology and Physics, by Marie-Louise von Franz (1974), explores parallels between the understanding of psychological healing in Jungian psychology and the theory of subatomic particles in quantum physics. Von Franz compares number symbolism in dreams with the mathematical structure of matter to link these two realms of life. The parallel role of numbers in the psyche and in matter is described to explain the interrelationship of our inner images and the outer world, as well to represent fundamental processes of personal development. 相似文献

Overestimation of one’s ability to argue their position on socio-political issues may partially underlie the current climate of political extremism in the U.S. Yet very little is known about what factors influence overestimation in argumentation of socio-political issues. Across three experiments, emotional investment substantially increased participants’ overestimation. Potential confounding factors like topic complexity and familiarity were ruled out as alternative explanations (Experiments 1–3). Belief-based cues were established as a mechanism underlying the relationship between emotional investment and overestimation in a measurement-of-mediation (Experiment 2) and manipulation-of-mediator (Experiment 3) design. Representing a new bias blind spot, participants believed emotional investment helps them argue better than it helps others (Experiments 2 and 3); where in reality emotional investment harmed or had no effect on argument quality. These studies highlight misguided beliefs about emotional investment as a factor underlying metacognitive miscalibration in the context of socio-political issues. 相似文献

Some cognitive abilities exhibit reliable gender differences, with females outperforming males in specific aspects of verbal ability, and males showing an advantage on certain spatial tasks. Among these cognitive gender differences, differences in mental rotation are the most robust, and appear to be present even in infants. A large body of animal research suggests that gonadal hormones, particularly testosterone, during early development could contribute to this gender difference in mental rotation. Also, substantial evidence supports an influence of socialization on mental rotation performance. The present study investigated the relationship of two types of factors, early postnatal testosterone exposure and parental attitudes about gender, to mental rotation performance in 61 healthy infants (29 males, 32 females). We measured salivary testosterone at two time points: 1–2.5 months of age and 5–6 months of age. Infants’ mental rotation performance and parents’ attitudes about gender were assessed at 5–6 months of age. As predicted, testosterone concentrations were significantly higher in boys than girls in early infancy (d = 0.54), and boys performed significantly better than girls on mental rotation (d = 0.64). A significant positive correlation between testosterone at age 1–2.5 months and mental rotation was found only in boys (r = 0.50, p = .01). A significant negative correlation between parents’ gender‐stereotypical attitudes and mental rotation performance was found only in girls (r = ?.57, p = .002). These findings suggest that the early postnatal testosterone surge (also known as “mini‐puberty”) may have organizational influences on mental rotation performance in boys, and that parents may influence their daughters’ mental rotation abilities beginning very early in life. 相似文献

What we call the Hilbert‐Bernays (HB) Theorem establishes that for any satisfiable first‐order quantificational schema S, there are expressions of elementary arithmetic that yield a true sentence of arithmetic when they are substituted for the predicate letters in S. Our goals here are, first, to explain and defend W. V. Quine's claim that the HB theorem licenses us to define the first‐order logical validity of a schema in terms of predicate substitution; second, to clarify the theorem by sketching an accessible and illuminating new proof of it; and, third, to explain how Quine's substitutional definition of logical notions can be modified and extended in ways that make it more attractive to contemporary logicians. 相似文献

The most recent edition of the American Psychological Association (APA) Manual states that two spaces should follow the punctuation at the end of a sentence. This is in contrast to the one-space requirement from previous editions. However, to date, there has been no empirical support for either convention. In the current study, participants performed (1) a typing task to assess spacing usage and (2) an eye-tracking experiment to assess the effect that punctuation spacing has on reading performance. Although comprehension was not affected by punctuation spacing, the eye movement record suggested that initial processing of the text was facilitated when periods were followed by two spaces, supporting the change made to the APA Manual. Individuals’ typing usage also influenced these effects such that those who use two spaces following a period showed the greatest overall facilitation from reading with two spaces. 相似文献

This paper reconvenes Samuel Beckett's psychotherapy with Wilfred Bion during 1934-1936 during which time Beckett's conceived and began writing this second novel, Murphy. Based on Beckett's visits to the Bethlem & Maudsley Hospital and his observation of the male nurses, the climax of Murphy is a chess match between Mr Endon (a male schizophrenic patient) and Murphy (a male psychiatric nurse). The precise notation of the Endon v Murphy chess match tells us that the Beckett intended it to be an exemplar of an anti-match, perhaps a metaphor for the tragedy of being locked into madness. It is also argued that the match offers us insight into Beckett's experience of the process of psychotherapy with Bion. Based on new information from Beckett's nephew and Bion's widow, hypotheses about the long term impact of the Bion-Beckett analysis are advanced as a mutual experience which shaped the lives and later literary output of both men, producing conjoined career writings which continue to offer us stark and sublime condensations of depression, psychosis, and the challenges of therapy and recovery. 相似文献

The defensive withdrawal reflexes of Aplysia californica have provided powerful behavioral systems for studying the cellular and molecular basis of memory formation. Among these reflexes the tail-elicited tail withdrawal reflex (T-TWR) has been especially useful. In vitro studies examining the monosynaptic circuit for the T-TWR, the tail sensory-motor (SN-MN) synapses, have identified the induction requirements and molecular basis of different temporal phases of synaptic facilitation that underlie sensitization in this system. They have also permitted more recent studies elucidating the role of synaptic and nuclear signaling during synaptic facilitation. Here we report the development of a novel, compartmentalized semi-intact T-TWR preparation that allows examination of the unique contributions of processing in the SN somatic compartment (the pleural ganglion) and the SN-MN synaptic compartment (the pedal ganglion) during the induction of sensitization. Using this preparation we find that the T-TWR is mediated entirely by central connections in the synaptic compartment. Moreover, the reflex is stably expressed for at least 24 h, and can be modified by tail shocks that induce sensitization across multiple temporal domains, as well as direct application of the modulatory neurotransmitter serotonin. This preparation now provides an experimentally powerful system in which to directly examine the unique and combined roles of synaptic and nuclear signaling in different temporal domains of memory formation. 相似文献
