The CQUniversity Australia Human Research Ethics Committee (HREC) is a human ethics research committee registered under the auspices of the National Health and Medical Research Council. In 2009 an external review of CQUniversity Australia’s HREC policies and procedures recommended that a low risk research process be available to the institution’s researchers. Subsequently, in 2010 the Human Research Ethics Committee Low Risk Application Procedure came into operation. This paper examines the applications made under the Human Research Ethics Committee Low Risk Application Procedure during the course of 2010 and 2011. The paper contributes to the literature analyzing the decision-making processes of research review committees through an analysis of the quantitative data relating to the low risk research applications made and through discourse analysis of the qualitative data represented by the assessment comments of the members of the Committee. 相似文献

This paper describes a study designed to investigate the efficacy of two traditional classical conditioning procedures in generating evaluative conditioning (EC) in the picture–picture paradigm in human participants. Differential EC was found using both simultaneous and trace conditioning procedures. In addition, the use of a block–subblock (BSB) nonpaired control condition and full counterbalancing of conditioned stimulus–unconditioned stimulus (CS–UCS) pairings across participants indicated that the observed EC effects were the result of associative learning. Examination of whether successful conditioning could take place with or without conscious awareness of CS–UCS contingencies was inconclusive. The results provide evidence for EC as an associative process and also provide some insight into the possible conditioning parameters that might successfully generate EC. 相似文献

The generation effect involves an improvement in memory when learners must complete or modify materials. Several researchers have suggested that this effect involves enhanced access to learners' existing memory representations; therefore, the effect should be less effective with meaningless, low meaningful, or unfamiliar material. In the present study, the authors conducted 4 experiments in which legal nonwords were used, and they found no generation effect. In another 2 experiments in which familiar clichés were contrasted with new sentences and with unfamiliar sentences from textbooks, the results showed a greatly reduced generation effect for the new, unfamiliar material. Those findings suggest that memory strategies that depend on the generation effect will have limited effectiveness when they are applied to new or unfamiliar material. 相似文献

The self-concept is a social, flexible construct that shifts in response to the salience of a relationship partner. Three related experiments found that the tendency to pursue closeness in relationships (as measured by attachment style) served as a moderator of the shift. Specifically, individuals who avoid closeness in relationships became less similar to salient friends via contrast effects, whereas those who pursued closeness in relationships became more similar to salient friends via assimilation effects. Results are discussed in terms of their implications for the nature of the self-concept and the importance of friendships. 相似文献

Mask mandates were commonplace around the world during the COVID-19 pandemic and essential to slowing the spread of SARS-CoV-2. However, it is still unclear whether and how masks impact social bonding. Building on past research examining the effects of masking on emotion recognition and social perception, the current research examines the effect of masking on feelings of social connectedness. Three studies (total N = 177) using videotaped introductions of masked and unmasked peers and varied assessments of desire for social connectedness yielded no differences as a function of masking. Although participants reported more difficulty hearing masked (vs. unmasked) peers, masking did not significantly impact other facets of communication or perception related to social bonding. When participants filmed their own introductory videos (Study 3), results showed increased expressivity within the masked (vs. unmasked) conditions, perhaps as a compensatory measure to aid bonding. These findings speak to the resiliency of the human need to belong and belonging-maintenance processes. 相似文献

The song control region in the avian forebrain is a series of discrete, interconnected nuclei mediating song learning and production. It has been studied in males or in species where both sexes sing. Little is known about the neural correlates of song perception in nonsinging females, often the intended recipients of song. We studied cowbirds (Molothrus ater), a species in which only males sing but in which females discriminate between males on the basis of song. We focused on nucleus lMAN because it has been implicated in early song acquisition, a stage relevant to both sexes to choose among competing acoustic models. We found that volume of lMAN was monomorphic in cowbirds. Moreover, the volume and neuronal number of female lMAN were positively correlated with selectivity of copulatory responding. The results provide strong evidence of nonsinging female's use of “song” control nuclei for song perception without the possibility of song production. 相似文献

Using a group correlational design and path analysis, the authors examined the relationships among personality, motivation, and internet gaming disorder (IGD). Findings showed that significant predictors of IGD included male gender, neurotic and introverted personality traits, and motivation related to achievement. 相似文献

Person recognition can be accomplished through several modalities (face, name, voice). Lesion, neurophysiology and neuroimaging studies have been conducted in an attempt to determine the similarities and differences in the neural networks associated with person identity via different modality inputs. The current study used event-related functional-MRI in 17 healthy participants to directly compare activation in response to randomly presented famous and non-famous names and faces (25 stimuli in each of the four categories). Findings indicated distinct areas of activation that differed for faces and names in regions typically associated with pre-semantic perceptual processes. In contrast, overlapping brain regions were activated in areas associated with the retrieval of biographical knowledge and associated social affective features. Specifically, activation for famous faces was primarily right lateralized and famous names were left-lateralized. However, for both stimuli, similar areas of bilateral activity were observed in the early phases of perceptual processing. Activation for fame, irrespective of stimulus modality, activated an extensive left hemisphere network, with bilateral activity observed in the hippocampi, posterior cingulate, and middle temporal gyri. Findings are discussed within the framework of recent proposals concerning the neural network of person identification. 相似文献
