This study examines the relationship of the psychological construct Entrepreneurial Orientation (EO) with business success in a sample of N?=?248 southern African business owners. We reintroduce the individual in EO research and show the importance of the person of the entrepreneur for business performance: Hierarchical regression analyses revealed significant relationships between EO components (personal initiative, achievement-, and risk-taking orientation) as well as overall EO and business performance. In addition, confirmatory factor analysis supported a single factor construct of EO that consists of learning, achievement, and autonomy orientation, competitive aggressiveness, innovative and risk-taking orientation, and of personal initiative.

In this study, we develop an individual-based psychological concept of Entrepreneurial Orientation (EO) and investigate the relationship between business owners' EO and business performance in southern Africa. EO has primarily been discussed from a firm-level perspective (e.g., ; ). It characterized businesses in their early years and was found to be important for firm success. In contrast, we apply a psychological approach with EO as an interindividual difference variable. Thus, our focus is the business owner and the general relationship between individual EO and performance of southern African small business owners.  相似文献

Visual search is typically faster when the target from the previous trial is repeated than when it changes. This priming effect is commonly attributed to a selection bias for the target feature value or against the nontarget feature value that carries over to the next trial. By contrast, according to a relational account, what is primed in visual search is the target–nontarget relationship—namely, the feature that the target has in relation to the features in the nontarget context (e.g., larger, darker, redder)—and switch costs occur only when the target–nontarget relations reverse across trials. Here, the relational account was tested against current feature-based views in three eye movement experiments that used different shape search tasks (e.g., geometrical figures varying in the number of corners). For all tested shapes, reversing the target–nontarget relationships produced switch costs of the same magnitude as directly switching the target and nontarget features across trials (“full-switch”). In particular, changing only the nontargets produced large switch costs, even when the target feature was always repeated across trials. By contrast, no switch costs were observed when both the target and nontarget features changed, such that the coarse target–nontarget relations remained constant across trials. These results support the relational account over feature-based accounts of priming and indicate that a target’s shape can be encoded relative to the shapes in the nontarget context.  相似文献

Decision making is informed by appraisals of appetitive cues and their associated opportunities for rewards. Such appraisals can be modulated by cognitive regulation strategies in order to promote goal-directed choices. Little is known about how cognitive regulation strategies, especially reappraisal, alter risk taking during decision making. To characterise the effect of reappraisal on risk taking, we systematically varied both the goal of regulation and the value of the decision options. Participants engaged in two reappraisal strategies with opposite goals, to increase (“emphasise”) or decrease (“de-emphasise”) the importance of an upcoming decision, during the presentation of cues signalling monetary decisions. The expected value of taking a risk was systematically varied across decisions such that a risky choice could be beneficial or disadvantageous. Reappraisal strategies increased or decreased risk taking in accordance both with regulation goals and expected value information. These results suggest that reappraisal can be used to flexibly alter behaviour associated with appetitive cues while maintaining value information.  相似文献

Regina Jonas (1902–44), who was ordained in Germany in 1935, is now widely recognised as the world's first female rabbi. However, for almost 50 years after her death at Auschwitz in 1944, she was given very little, if any, public recognition. Based on archival research, interviews and critical engagement with secondary literature, this paper investigates a range of explanations why Jonas was nearly lost to historiography. It also considers the circumstances of the rediscovery of this controversial figure in the early 1990s and explores how she is remembered today. This paper raises important issues in relation to historiography and the connection between processes of remembering, forgetting and identity formation, particularly in relation to the history of the ordination of female rabbis and the history of Jewish communities in Germany.  相似文献

Previous research into the mechanisms of task switching has shown that repeating the same response in a different task context is associated with costs. To investigate whether such response-repetition costs occur even when the first of the two responses is not overtly executed, we used a variant of the change-signal paradigm. Subjects responded to a first stimulus by pressing a left or right response key. In half of the trials, a second stimulus occurred after a variable, adaptively adjusted delay, indicating to abandon the first response, and only respond to the second stimulus using another set of left and right response keys. In Experiment 1, different tasks had to be performed with the first and second stimulus (task-switch condition); in Experiment 2, the same task had to be performed with both stimuli (task-repetition condition). Response-repetition costs were obtained in Experiment 1, and response-repetition benefits in Experiment 2. Importantly, these costs and benefits were obtained even when the first of the two responses had not been overtly executed. The data support the idea that interference of task-specific response codes occurs at the level of abstract response codes. Interference of such response codes occurs even when the responses are not overtly executed.  相似文献

Using straight translatory motion of a visual peripheral cue in the frontoparallel plane, and probing target discrimination at different positions along the cue's motion trajectory, we found that target orientation discrimination was slower for targets presented at or near the position of motion onset (4.2° off centre), relative to the onset of a static cue (Experiment 1), and relative to targets presented further along the motion trajectory (Experiments 1 and 2). Target discrimination was equally fast and accurate in the moving cue conditions relative to static cue conditions at positions further along the cue's motion trajectory (Experiment 1). Moreover, target orientation discrimination was not slowed at the same position, once this position was no longer the motion onset position (Experiment 3), and performance in a target colour-discrimination task was not slowed even at motion onset (Experiment 4). Finally, we found that the onset location of the motion cue was perceived as being shifted in the direction of the cue's motion (Experiment 5). These results indicate that attention cannot be as quickly or precisely shifted to the onset of a motion stimulus as to other positions on a stimulus’ motion trajectory.  相似文献

In a field study, we conducted a soccer penalty experiment in which players had to detect the goalkeeper's movement during the run-up. We tested subjects under two conditions: the center-looking (perceiving both stimuli peripherally) and the free gaze strategy (foveal gaze on either the ball or the goalkeeper, or saccades). The center-looking strategy was superior when it came to detecting goalkeeper movements; with respect to the number of scored goals, no difference could be detected. Future research should investigate whether appropriate training in the use of the center-looking strategy might lead to a higher number of scored goals.  相似文献

This discussion lauds the main thrust of Dr. Knafo's paper, which is the crucially important, and too often neglected, role of solitude in the fullest development of self. Questions are raised regarding conflicting aspects of solitude as presented, and clarification from Dr. Knafo is sought. In addition further explication is requested on some of her points of view. The abiding response from this discussant is “Bravo.”  相似文献

When we observe someone shift their gaze to a peripheral event or object, a corresponding shift in our own attention often follows. This social orienting response, joint attention, has been studied in the laboratory using the gaze cueing paradigm. Here, we investigate the combined influence of the emotional content displayed in two critical components of a joint attention episode: The facial expression of the cue face, and the affective nature of the to-be-localized target object. Hence, we presented participants with happy and disgusted faces as cueing stimuli, and neutral (Experiment 1), pleasant and unpleasant (Experiment 2) pictures as target stimuli. The findings demonstrate an effect of ‘emotional context’ confined to participants viewing pleasant pictures. Specifically, gaze cueing was boosted when the emotion of the gazing face (i.e., happy) matched that of the targets (pleasant). Demonstrating modulation by emotional context highlights the vital flexibility that a successful joint attention system requires in order to assist our navigation of the social world.  相似文献
