The correlation between three conceptions of social presence (seen as 1. a subjective quality of a medium that determines
the quality of the communication and perception of others, 2. self-projection onto the group, and 3. identification with the
group) and different aspects of perceived learning in online discussion groups were tested. Six hundreds and fifty nine students
completed a web-based questionnaire that was distributed via 50 course Websites. Self projection, perception of others and
identification with the group correlated positively with each other. They also correlated positively with most aspects of
perceived learning. The subjective quality of the medium did not correlate with these conceptions and also did not correlate
with any aspects of perceived learning. Thus, social presence may afford learning by setting a convenient climate. Alternatively,
it may contribute only to the socioemotional source of perceived learning while leaving cognitive source unaffected.

Some courts have ruled that identification evidence provided by a police officer is more likely to be accurate than comparable evidence provided by a civilian. Identifications made by a police officer are therefore given greater weight and, for these identifications, otherwise-required procedures and safeguards might be deemed superfluous. We describe the available evidence that examines these notions and argue that police officers actually have no advantage at all over civilians when making identifications. In a recent publication, however, Tupper et al. (2023, Applied Cognitive Psychology, 37, 845–860) offer data that they suggest challenge this claim. We argue that their data, when appropriately analyzed, once again show no police advantage. Their findings therefore converge with the results of 12 prior studies, comparing the identification accuracy for police officers and civilians. We conclude that the best summary of the available data is that the suggestion of a police officer identification advantage is a myth. 相似文献

Given the recognised benefits of organisational identification (OI) on workers' well-being, we investigated the underlying mechanisms of this association in this work. We conducted a cross-sectional study (N = 192) to examine the possible mediating role of three factors related to individuals' workplace experiences (organisational trust, the meaning of work and self-objectification) in the relationship between OI and well-being. Specifically, the research aims to examine the relationship between identification in the workplace and favourable well-being outcomes. The study results demonstrated the significant indirect effects of the hypothesised model. In particular, OI was positively related to well-being via increased trust and meaning of work and through a reduced self-objectification experience. The findings highlight the significance of OI in relation to distal outcomes despite the potential presence of negative perceptual experiences within the relationship. This study seeks to offer innovative perspectives through which we can observe the relationship between less-examined variables within the workplace, thus providing guidance for practitioners and researchers in this field. 相似文献

COVID-19 vaccination is widely regarded as an individual decision, resting upon individual characteristics and demographic factors. In this research, we provide evidence that psychological group membership, and more precisely, social cohesion—a multidimensional concept that encompasses one's sense of connectedness to, and interrelations within, a group—can help us understand COVID-19 vaccination intentions (Study 1) and uptake (Study 2). Study 1 is a repeated-measures study with a representative sample of 3026 Australians. We found evidence that social cohesion can be conceptualised as a multidimensional structure; moreover, social cohesion at Wave 1 (early in the COVID-19) predicted greater vaccination intention and lower perceived risk of vaccination at Wave 2 (4 months later). In Study 2 (a cross-sectional study, N = 499), the multidimensional structure of social cohesion was associated with greater uptake of vaccine doses (in addition to willingness to receive further doses and perceived risk of the vaccine). These relations were found after controlling for a series of demographic (i.e., sex, age, income), health-related factors (i.e., subjective health; perceived risk; having been diagnosed with COVID-19), and individual differences (political orientation, social dominance orientation, individualism). These results demonstrate the need to go beyond individual factors when it comes to behaviours that protect groups, and particularly when examining COVID-19 vaccination—one of the most important ways of slowing the spread of the virus. 相似文献

The development in the interface of smart devices has lead to voice interactive systems. An additional step in this direction is to enable the devices to recognize the speaker. But this is a challenging task because the interaction involves short duration speech utterances. The traditional Gaussian mixture models (GMM) based systems have achieved satisfactory results for speaker recognition only when the speech lengths are sufficiently long. The current state-of-the-art method utilizes i-vector based approach using a GMM based universal background model (GMM-UBM). It prepares an i-vector speaker model from a speaker’s enrollment data and uses it to recognize any new test speech. In this work, we propose a multi-model i-vector system for short speech lengths. We use an open database THUYG-20 for the analysis and development of short speech speaker verification and identification system. By using an optimum set of mel-frequency cepstrum coefficients (MFCC) based features we are able to achieve an equal error rate (EER) of 3.21% as compared to the previous benchmark score of EER 4.01% on the THUYG-20 database. Experiments are conducted for speech lengths as short as 0.25 s and the results are presented. The proposed method shows improvement as compared to the current i-vector based approach for shorter speech lengths. We are able to achieve improvement of around 28% even for 0.25 s speech samples. We also prepared and tested the proposed approach on our own database with 2500 speech recordings in English language consisting of actual short speech commands used in any voice interactive system. 相似文献

This article provides a response to five excellent commentaries on our article ‘Super‐recognizers: From the lab to the world and back again’. Specifically, the response summarizes commonalities between these commentaries. Based on this consensus, we propose a flexible framework for the assessment of superior face recognition and outline guiding principles to advance future work in the field. 相似文献

The purpose of this systematic review was to identify investigations comparing the efficacy of alternative modality (e.g., pictorial, verbal, video) stimulus preference assessments for individuals with developmental disabilities. We identified articles by searching peer‐reviewed journals using the PsycINFO and ERIC databases, conducting table of contents searches of common behavioral outlets, and conducting ancestral searches of recent reviews and practitioner summaries of preference assessment methodology. A total of 32 articles met our inclusion criteria. These studies were then coded across a variety of features to gain a better understanding of the efficacy of alternative format preference assessments for individuals with developmental disabilities. In addition, we reviewed this literature for the use of prerequisite‐skill assessments and contingent‐reinforcer access to further investigate the relation between these variables and the accuracy of pictorial, verbal, and video preference assessments. A variety of methodological concerns are discussed as well as suggestions for future research. 相似文献

Cross-unit ties–relationships that facilitate discretionary information sharing between individuals from different business units–offer a range of organizational benefits. Scholars argue that organizations can promote cross-unit ties by: (a) formally bringing together individuals from different business units into structural links (e.g., cross-unit strategic committees) to encourage the formation of new cross unit ties and, (b) transferring individuals across units, which can increase cross-unit interaction when ties to the prior unit are maintained. This study considers the notion that the success of these formal interventions in fostering cross-unit interaction is contingent on identification with the local unit relative to identification with the broader organization. Specifically, we propose that structural links are more likely to foster cross-unit ties when organizational identification is high and unit identification is low. In contrast, lateral transfers are more likely to result in cross-unit ties when both organizational identification and unit identification are high. We find general support for these propositions in data obtained from a sample of senior leaders of a Fortune 200 agribusiness company before and after a restructuring designed to stimulate cross-unit information sharing. Our model and results make important contributions to our understanding of the relationship between formal and informal structure and reconcile conflicting views regarding the moderating effect of unit identification on intergroup relations. 相似文献
