Researchers have evaluated how broad categories of emotion (i.e. positive and negative) influence judgments of learning (JOLs) relative to neutral items. Specifically, JOLs are typically higher for emotional relative to neutral items. The novel goal of the present research was to evaluate JOLs for fine-grained categories of emotion. Participants studied faces with afraid, angry, sad, or neutral expressions (Experiment 1) and with afraid, angry, or sad expressions (Experiment 2). Participants identified the expressed emotion, made a JOL for each, and completed a recognition test. JOLs were higher for the emotional relative to neutral expressions. However, JOLs were insensitive to the categories of negative emotion. Using a survey design in Experiment 3, participants demonstrated idiosyncratic beliefs about emotion. Some people believed the fine-grained emotions were equally memorable, whereas others believed a specific emotion (e.g. anger) was most memorable. Thus, beliefs about emotion are nuanced, which has important implications for JOL theory.  相似文献

Based on the adaptive lie detector theory, this study is an examination of whether taking an oath, as context‐general information, increases the credibility of a suspect. The consistency of the testimonies of 6 eyewitnesses was manipulated so that it could be used as individuating information. There were 2 sets of testimonies: one that was consistent and one that was inconsistent. The results supported the adaptive lie detector theory. The participants judged those persons who took an oath to be more credible than those who did not, but this only happened in situations where the testimonies of the eyewitnesses were inconsistent. The theoretical and practical implications of the findings and future directions are then discussed.  相似文献

The structure of people's conceptual knowledge of concrete nouns has traditionally been viewed as hierarchical ( Collins & Quillian, 1969 ). For example, superordinate concepts ( vegetable ) are assumed to reside at a higher level than basic-level concepts ( carrot ). A feature-based attractor network with a single layer of semantic features developed representations of both basic-level and superordinate concepts. No hierarchical structure was built into the network. In Experiment and Simulation 1, the graded structure of categories (typicality ratings) is accounted for by the flat attractor network. Experiment and Simulation 2 show that, as with basic-level concepts, such a network predicts feature verification latencies for superordinate concepts ( vegetable ). In Experiment and Simulation 3, counterintuitive results regarding the temporal dynamics of similarity in semantic priming are explained by the model. By treating both types of concepts the same in terms of representation, learning, and computations, the model provides new insights into semantic memory.  相似文献

The distinguishing characteristic of complex co-evolving systems is their ability to create new order. In human systems this may take the form of new ways of working or relating, new ideas for products, procedures, artefacts, or even the creation of a different culture or a new organizational form. This article will explore the creation of new order using the principles of complexity and the concepts of creativity and innovation. It will argue that innovation can be facilitated by an enabling environment based on the logic of complexity and describe how one organization (the Humberside Training and Enterprise Council) co-created an innovative environment and changed its culture, ways of working, thinking, and relating.  相似文献

One approach to hypnosis suggests that for hypnotic experience to occur frontal lobe activity must be attenuated. For example, cold control theory posits that a lack of awareness of intentions is responsible for the experience of involuntariness and/or the subjective reality of hypnotic suggestions. The mid-dorso-lateral prefrontal cortex and the ACC are candidate regions for such awareness. Alcohol impairs frontal lobe executive function. This study examined whether alcohol affects hypnotisability. We administered 0.8 mg/kg of alcohol or a placebo to 32 medium susceptible participants. They were subsequently hypnotised and given hypnotic suggestions. All participants believed they had received some alcohol. Participants in the alcohol condition were more susceptible to hypnotic suggestions than participants in the placebo condition. Impaired frontal lobe activity facilitates hypnotic responding, which supports theories postulating that attenuation of executive function facilitates hypnotic response, and contradicts theories postulating that hypnotic response involves enhanced inhibitory, attentional or other executive function.  相似文献

Many studies have found the font size of to-be-remembered words has a significant influence on judgments of learning (JOLs). However, few studies have investigated whether JOLs are affected by the mental imagery size of to-be-remembered words, even when the font sizes themselves are kept identical in study materials. This study investigated whether the visual mental imagery size influences the participants’ JOLs and what the underlying mechanisms are. In Experiments 1 and 2, participants learned words with identical font sizes, mentally generated large or small imageries and then made JOLs. We found that JOLs under the large imagery condition were significantly higher than those under the small imagery condition, but actual recall performance exhibited no significant difference. In Experiment 3, participants pressed a button immediately after mental imagery generation and showed that it took significantly longer to generate large imageries than to generate small imageries, and the difference in JOLs between two conditions was no longer significant. In Experiment 4, we used a questionnaire to investigate the contribution of beliefs and found that participants believed large imageries were easier to remember. These findings indicate that imagery size has a significant impact on JOLs, in which beliefs may play a leading role.  相似文献

SEM (N = 182) was employed to examine implied temporal aspects of three-component commitment theory as they relate to turnover. Consistent with expectations, affective commitment predicted subsequent turnover in an immediate and relatively short interval of 4 months, but failed to do in a much longer but outlying interval of 5–12 months. Side bet commitment failed to predict turnover in the short, immediate interval, but did so robustly over the longer albeit more distant interval. Normative commitment predicted turnover in neither the near term nor outmonths. Turnover rates for employees with low affective commitment were much higher than those with high affective commitment in the first quarter of a 1-year monitoring period, but subsequent turnover rates were roughly the same for the two groups. In contrast, turnover for employees with low side bet commitment was only slightly higher than the high side bet group in the first quarter, but over the remainder of the year cumulative turnover for the low side bet group exceeded that for the high side bet group by increasingly large margins. These results are consistent with theory suggesting that decrements in affective commitment (1) often occur suddenly and just prior to employees' leaving and (2) reflect general disaffection and an impetus to leave that is already exists at the point of attitude measurement. Results comport with theory describing side bet commitment as (1) an appraisal of leaving costs that, in the aggregate, are unlikely to change suddenly and (2) a relatively stable attitude that serves primarily to prevent turnover should some independent motivation to leave arise.  相似文献

In everyday life people estimate completion times for projects in the near and distant future. How might the temporal proximity of a project influence prediction? Given that closer events elicit more concrete construals, we proposed that temporal proximity could enhance two kinds of concrete cognitions pertinent to task completion predictions: step-by-step plans and potential obstacles. Although these cognitions have opposite implications for prediction, and thus could cancel each other out, we hypothesized that temporal proximity would have a greater impact on cognitions that were relatively focal. Thus contextual factors that alter the relative focus on plans vs. obstacles should determine whether and how temporal proximity affects prediction. Six studies supported this reasoning. In contexts that elicited a focus on planning, individuals predicted earlier completion times for close than distant projects. In contexts that prompted a focus on obstacles, individuals predicted later completion times for close than distant projects.  相似文献
