Although the validity of collecting quantitative data using electronic platforms has been widely accepted, there has been concern that qualitative data collected on an electronic platform may not provide the same depth and richness in response quality as data collected using the pen-and-paper format. This article compares the quality of responses to open-ended questions collected using the pen-and-paper platform with responses collected using an electronic platform. Data for a program evaluation study were collected using either the pen-and-paper platform, an iPad, or an iPad Mini at a series of after-hours events for adults at the Center of Science and Industry, a Midwest science center. Metrics were designed to calculate a comprehensive response score consisting of the breadth of information and the richness of detail in open-ended item responses, allowing us to compare the overall response quality between the three platforms. Results indicate that qualitative data collected using electronic devices are as broad and detailed as data collected using traditional pen-and-paper techniques.  相似文献

Despite the enormous revenues generated by the video game industry in recent years, relatively little research has been undertaken into consumer preferences and the determinants of video game consumption. This study addresses this deficiency through the analysis of data from a popular online video game that includes historic behavioural information for 1,408 consumers participating in 728,811 unique rounds of gameplay. We analyse these data with the goal of estimating determinants of the aggregate amount of time that a consumer spends playing the game. Through the estimation of duration models, we show that less experienced consumers are less likely to continue playing the game at any given point, possibly due to having achieved mastery and becoming bored. However, we also find that consumers tend to play the game for longer periods when using a wider range of character roles and vehicles, implying that a consumer's interest can be maintained through exposure to greater variety. Our results represent the first such evidence on in‐game consumer preferences, which has important implications for video game consumption through optimisation of gameplay experiences to satisfy these preferences.  相似文献

In a recent paper, Kyselo (2014) argues that an enactive approach to selfhood can overcome ‘the body-social problem’: “the question for philosophy of cognitive science about how bodily and social aspects figure in the individuation of the human individual self” (Kyselo 2014, p. 4; see also Kyselo and Di Paolo (2013)). Kyselo’s claim is that we should conceive of the human self as a socially enacted phenomenon that is bodily mediated. Whilst there is much to be praised about this claim, I will demonstrate in this paper that such a conception of self ultimately leads to a strained interpretation of how bodily and social processes are related. To this end, I will begin the paper by elucidating the body-social problem as it appears in modern cognitive science and then expounding Kyselo’s solution, which relies on a novel interpretation of Jonas’s (1966/2001) concept of needful freedom. In response to this solution, I will highlight two problems which Kyselo’s account cannot overcome in its current state. I will argue that a more satisfactory solution to the body-social problem involves a re-conception of the human body as irrevocably socially constituted and the human social world as irrevocably bodily constituted. On this view, even the most minimal sense of selfhood cannot privilege either bodily or social processes; instead, the two are ontologically entwined such that humans are biosocial selves.  相似文献

Empirical research has documented the attitudinal and behavioral consequences of sexual harassment, but has not examined the physiological consequences. In the present study, we monitored women's autonomic physiological activity while they performed a word‐association task with a male confederate who was either harassing, egalitarian, or submissive. Subsequently, we examined the women's cognitive, affective, and physiological reactions as they prepared and delivered a speech to the same confederate. Results indicate that harassment led to greater cardiovascular reactivity during the word‐association task and to greater cognitive, negative affective, and cardiovascular reactions during the subsequent speech compared with other conditions. Subgroups of harassed women who confronted their coworker, or who blamed themselves for his behavior, also exhibited greater cardiovascular reactivity during both tasks compared to women who did not use these coping responses. We integrate our laboratory results with those obtained in field settings.  相似文献

This study utilizes data from the National Survey of American Life to examine the sociodemographic and denominational correlates of religious involvement and spirituality among older African Americans and Black Caribbeans. Eleven measures of non-organizational religious participation, subjective religiosity, and spirituality are utilized. The findings indicate significant gender, income, region, marital status, denominational, and immigration status differences in religiosity and spirituality. Among older Black Caribbeans, income was a consistent correlate of religious participation and spirituality. The findings are discussed in relation to prior work in the area of religious involvement among older adults.  相似文献

The indispensability argument is a method for showing that abstract mathematical objects exist (call this mathematical Platonism). Various versions of this argument have been proposed (§1). Lately, commentators seem to have agreed that a holistic indispensability argument (§2) will not work, and that an explanatory indispensability argument is the best candidate. In this paper I argue that the dominant reasons for rejecting the holistic indispensability argument are mistaken. This is largely due to an overestimation of the consequences that follow from evidential holism. Nevertheless, the holistic indispensability argument should be rejected, but for a different reason (§3)—in order that an indispensability argument relying on holism can work, it must invoke an unmotivated version of evidential holism. Such an argument will be unsound. Correcting the argument with a proper construal of evidential holism means that it can no longer deliver mathematical Platonism as a conclusion: such an argument for Platonism will be invalid. I then show how the reasons for rejecting the holistic indispensability argument importantly constrain what kind of account of explanation will be permissible in explanatory versions (§4).  相似文献

By attenuating neural and perceptual responses to sustained stimulation, adaptation enhances the detection of new, transient stimuli. Disadaptation serves a similarly important role as a temporal filter for chemoreceptor cells, producing rapid recovery of sensitivity upon termination of the adapting odorant. Previous research from our laboratory indicated that a rapid form of odor adaptation can be measured using a novel, simultaneous-odorant paradigm. In the present study, we extended the earlier method by measuring recovery from adaptation. Perceptual odor adaptation was measured by estimating psychophysical detection thresholds in a group of college-aged student volunteers (N = 20; 12 females, eight males) for a self-adapting odorant, vanilla extract. To induce adaptation, the time between the onset of the adapting odorant and the onset of the target odorant was systematically varied. By first quantifying adaptation, recovery of sensitivity could therefore be investigated by using different time points following the termination of the adapting odorant. Consistent with our previous work, thresholds estimated in the presence of the simultaneous adapting odorant were significantly increased, reflecting a decrease in sensitivity due to adaptation. Conversely, approximately 100 ms following termination of the adapting stimulus (the briefest delay tested), sensitivity began to rapidly recover. Nevertheless, some residual adaptation was evident at the longest offset delay of 500 ms. These findings suggest that the recovery from adaptation proceeds at least as rapidly as the onset of adaptation, a finding that is consistent with physiological evidence from olfactory receptors. These data also suggest the effectiveness of this new odorant paradigm in characterizing the temporal characteristics underlying these critical olfactory mechanisms.  相似文献
