Interleaved practice (i.e., exemplars from different categories are intermixed within blocks) has been shown to enhance induction performance compared to blocked practice (i.e., exemplars from the same category are presented sequentially). The main aim of the present study was to examine explanations of why interleaved practice produces this benefit in category induction (known as the interleaving effect). We also evaluated two hypotheses, the attention attenuation hypothesis and the discriminative-contrast hypothesis, by collecting data on participants’ fixation on exemplars, provided by eye-tracking data, and manipulating the degree of discriminative-contrast. In Experiments 1 and 2, participants were instructed to learn the style of 12 new artists in blocked and interleaved practice in fixed-paced and self-paced learning conditions, respectively. We examined fixation durations for six positions (temporal sequence of exemplars presented in each block) using eye-tracking. The results of the two experiments, based on eye-tracking data, suggested that attention attenuation may not be the primary mechanism underlying the interleaving effect in category induction. In Experiment 3, we manipulated the degree of discriminative-contrast to examine the impact on the interleaving effect in category induction. The results showed that the main effect of the degree of discriminative-contrast was significant, and performance in the high-contrast condition was significantly better than those in the medium-contrast and low-contrast conditions. Thus, the current results support the discriminative-contrast hypothesis rather than the attention attenuation hypothesis.

This study examines the impact of photographic–textual and risk–benefit frames on the level of visual attention, risk perception, and public support for nuclear energy and nanotechnology in Singapore. Using a 2 (photographic–textual vs. textual-only frames) × 2 (risk vs. benefit frames) × 2 (nuclear energy vs. nanotechnology) between-subject design with eye-tracking data, the results showed that photographic–textual frames elicited more attention and did have partial amplification effect. However, this was observable only in the context of nuclear energy, where public support was lowest when participants were exposed to risk frames accompanied by photographs. Implications for theory and practice were discussed.

This paper investigates the impact of having open 400 meter (400 m) runners on NCAA relay teams. Using data from 2012–2016 containing the top 100 4 × 400 m in each NCAA Division relay times for each year, it is found that more 400 m specialists lead to an increase in the overall performance of the team, measured by a decrease in relay times. The effect is examined across Division I–III NCAA track teams. The results are consistent across each division. We view this as a test of the role of specialization on performance. Using runners who specialize in 400 m races should increase overall team performance as long as specialization does not lead to an inefficient allocation of team human capital. An additional performance measure is used examining the difference between projected and actual relay times. Divisions I and II are found to perform better than projected with an increase in 400 m runners, but there is no effect found in Division III.

Purpose – The purpose of this paper is to examine the impact of family ownership on firm performance. In particular the authors investigate whether family firms outperform non-family firms and whether first generation family firms perform better than second generation family firms in an emerging economy using Bangladesh as a case. Design/methodology/approach – This study uses a data set of 141 listed Bangladeshi non-financial companies for the period 2005-2009. The methodology is based on multivariate regression analysis. Findings – The result shows that family firms perform better than their non-family counterparts. The authors also find that family ownership has a positive impact on firm performance. The analysis further reveals intergenerational differences where family firms and performance are associated positively only when founder members act as CEOs or chairmen. However, when descendents serve as CEOs or chairmen family firms are associated with poorer firm performance. Originality/value – The authors extend the findings of previous studies that investigate the family ownership and firm performance relationship in developed economy settings, but neglected emerging economies. The study also informs the literature about the intergenerational impact of family firms on performance in an emerging market.

The effect of social facilitation, particularly the impact of perceived evaluation and relative competence of handicapped learners, was tested to determine its efficacy in predicting 26 learning disabled children's oral reading performance. Two conditions reflected the competence variable: low relative competence and similar relative competence. The dependent measure was number of oral reading errors. Results revealed a significant main effect, indicating that children who read with similar-ability peers performed significantly better than when they read with peers of superior ability. Results are discussed in relation to mainstreaming decisions and homogeneous groupings of students for direct academic instruction.

Source Of Information

Attentional narrowing refers to a state in which operators, involuntarily and unconsciously, fail to process a subset of potentially critical information. Little is known about factors that trigger the phenomenon and how to detect and distinguish it from a related state, focused attention, where one deliberately concentrates on one source of information. The objectives of this study were to (1) evaluate the effectiveness of three factors - workload, a novel difficult problem and incentive - for inducing attentional narrowing, and (2) identify markers of attentional narrowing and focused attention. Performance, eye-tracking data and anxiety levels were recorded while participants timeshared numerous tasks. When confronted with a novel problem, participants’ visual attention narrowed towards the affected task, and performance dropped on several tasks when all three factors were present. The findings from this study highlight promising means of inducing narrowing and show that eye-tracking, together with performance data, enable real-time detection of attentional narrowing.

Abstract The recent years have witnessed the emergence of new approaches in filmmaking including virtual reality (VR), which is meant to achieve an immersive viewing experience through advanced electronic devices, such as VR headsets. The VR industry is oriented toward developing content mainly in English and Japanese, leaving vast audiences unable to understand the original content or even enjoy this novel technology due to language barriers. This paper examines the impact of the subtitles on the viewing experience and behaviour of eight Arab participants in understanding the content in Arabic through eye tracking technology. It also provides an insight on the mechanism of watching a VR 360-degree documentary and the factors that lead viewers to favour one subtitling mode over the other in the spherical environment. For this end, a case study was designed to produce 120-degree subtitles and Follow Head Immediately subtitles, followed by the projection of the subtitled documentary through an eye tracking VR headset. The analysis of the eye tracking data is combined with post-viewing interviews in order to better understand the viewing experience of the Arab audience, their cognitive reception and the reasons leading to favour one type of subtitles over the other.

This paper aims at filling existing research by examining the impact of corporate governance and ownership structure on firm performance using cross-sectional data from companies in the MENA region for the years 2009-2013. The results indicate that higher ownership concentration is associated with higher returns. Furthermore, firms with higher international ownership share tend to perform better than those with only local private and/or state ownership. The results suggest some prevalent features with respect to ownership and performance of firms in the MENA region. Due to the volatile social and business environment, these firms operate in, they may be particularly dependent on effective ownership structures and support which may be provided by international, institutional, and large shareholders.

This study examined the impact of a social support manipulation on performance. Participants with high and low levels of perceived support were randomly assigned to an experimental support or control condition, before completing a golf-putting task. Participants with high levels of perceived support performed at a higher level than those with low levels of perceived support. Participants in the support condition performed at a higher level than those in the control condition. A significant interaction was primarily attributable to the low perceived support participants in the support condition performing better than the low perceived support participants in the control condition. Participants in the support condition also experienced less frequent and distracting task-irrelevant thoughts compared with those in the control condition. These results suggest that experimentally manipulated support may lead to improvements in the performance of novices completing a golf-putting task, and that such support may be particularly important for those low in perceived support.

The Impact

Machine learning, particularly classification algorithms, constructs mathematical models from labeled data that can predict labels for new data. Using its capability to identify distinguishing patterns among multi-dimensional data, we investigated the impact of three factors on the observation of architectural scenes: Individuality, education, and image stimuli. An analysis of the eye-tracking data revealed that (1) a velocity histogram was unique to individuals, (2) students of architecture and other disciplines could be distinguished via endogenous parameters, but (3) they were more distinct in terms of seeking structural versus symbolic elements. Because of the reverse nature of the classification algorithms that automatically learn from data, we could identify relevant parameters and distinguishing eye-tracking patterns that have not been reported in previous studies.
