The marketing materials of remote eye-trackers suggest that data quality is invariant to the position and orientation of the participant as long as the eyes of the participant are within the eye-tracker’s headbox, the area where tracking is possible. As such, remote eye-trackers are marketed as allowing the reliable recording of gaze from participant groups that cannot be restrained, such as infants, schoolchildren and patients with muscular or brain disorders. Practical experience and previous research, however, tells us that eye-tracking data quality, e.g. the accuracy of the recorded gaze position and the amount of data loss, deteriorates (compared to well-trained participants in chinrests) when the participant is unrestrained and assumes a non-optimal pose in front of the eye-tracker. How then can researchers working with unrestrained participants choose an eye-tracker? Here we investigated the performance of five popular remote eye-trackers from EyeTribe, SMI, SR Research, and Tobii in a series of tasks where participants took on non-optimal poses. We report that the tested systems varied in the amount of data loss and systematic offsets observed during our tasks. The EyeLink and EyeTribe in particular had large problems. Furthermore, the Tobii eye-trackers reported data for two eyes when only one eye was visible to the eye-tracker. This study provides practical insight into how popular remote eye-trackers perform when recording from unrestrained participants. It furthermore provides a testing method for evaluating whether a tracker is suitable for studying a certain target population, and that manufacturers can use during the development of new eye-trackers. 相似文献

Is Facebook usage bad for mental health? Existing studies provide mixed results, and direct evidence for neural underlying moderators is lacking. We suggest that being able to filter social-network information from accessing working memory is essential to preserve limited cognitive resources to pursue relevant goals. Accordingly, among individuals with impaired neural social-network filtering ability, enhanced social-network usage would be associated with negative mental health. Specifically, participants performed a novel electrophysiological paradigm that isolates neural Facebook filtering ability. Participants’ actual Facebook behavior and anxious symptomatology were assessed. Confirming evidence showed that enhanced Facebook usage was associated with anxious symptoms among individuals with impaired neural Facebook filtering ability. Although less robust and tentative, additional suggestive evidence indicated that this specific Facebook filtering impairment was not better explained by a general filtering deficit. These results involving a neural social-network filtering moderator, may help understand for whom increased online social-network usage is associated with negative mental health. 相似文献

Affordances are possibilities for action offered by the environment. Recent research on affordances holds that there are differences in how people experience such possibilities for action. However, these differences have not been properly investigated. In this paper I start by briefly scrutinizing the existing literature on this issue, and then argue for two claims. First, that whether an affordance solicits action or not depends on its relevance to the agent’s concerns. Second, that the experiential character of how an affordance solicits action depends on the character of the concern to which it is relevant. Concerns are conceived of as bodily forms of responsiveness, and solicitations are experienced through this responsiveness. The main aim of this paper is to make clear that an understanding of experiential differences in solicitations has to be based on a phenomenological appreciation of how one experiences one’s responsiveness to those solicitations. In the remainder of the paper I show how such a phenomenological appreciation reveals several characteristics of our responsiveness and I briefly explore three of them: valence, force and mineness. In the final section I discuss the self-referentiality of affordances in light of the current proposal, and argue that this self-referentiality is broader than is typically acknowledged. 相似文献

Models of consciousness differ in whether they predict a gradual change or a discontinuous transition between nonconscious and conscious perception. Sergent and Dehaene (Psychological Science, 15, 720-728, 2004) asked subjects to rate on a continuous scale the subjective visibility of target words presented during an attentional blink. They found that these words were either detected as well as targets outside the attentional-blink period or not detected at all, and interpreted these results as support for a discontinuous transition between nonconscious and conscious processing. We present results from 4 attentional-blink experiments showing that this all-or-none rating pattern disappears with the use of an alternative measure of consciousness (post-decision wagering) and a more difficult identification task. Instead, under these circumstances, subjects used the consciousness rating scales in a continuous fashion. These results are more consistent with models that assume a gradual change between nonconscious and conscious perception during the attentional blink. 相似文献

This paper addresses the strange bedfellowship between psychoanalysis and cinema since the century's turn. Its specific focus is the idiosyncratic psychoanalysis/psychotherapy practised in mainstream cinema and television. Cinetherapists have consistently fallen into one of three categories: Dr. Dippy, a focus of derision, weirder than his patients; Dr. Evil, Hollywood's psychiatric version of the mad, bad scientist; and the unfailingly benevolent, self-sacrificing Dr. Wonderful. The prevalence of these stereotypes has waxed and waned according to shifting cultural circumstances. The study concludes with reflections on the possible impact, deleterious or otherwise, of distorted filmic images of the impossible profession. 相似文献

We reported on a subject with nonfluent primary progressive aphasia (PPA), NL, who demonstrated an impaired ability to make rhyme judgments (Dowhaniuk, Dixon, Roy, Black, & Square, in press). Our hypothesis was that these deficits represent a precursor to phonological alexia. However, no definitive evidence supported the existence of a phonological reading impairment as NL made relatively few errors reading nonwords. To further evaluate NL's nonword reading, nonword and real word reaction times were compared. NL's reaction times were significantly longer for only nonwords compared to the slowest control subject. We then assessed the first two stages of processing involved in nonword reading (Coltheart, 1996). NL did not demonstrate deficits with graphemic parsing or phoneme assignment. His continuing problems with auditory rhyme judgments support the presence of a phonological processing deficit not specific to reading. We conclude that reaction time measures allow for the detection of subtle nonword reading deficits. 相似文献

In order to identify differences in risk factors for suicide attempts throughout adolescence, this study utilized a school-based survey of ninth (n = 1,192) and eleventh graders (N = 1,055). Suicide attempts were associated with cigarette and alcohol use, family violence, and depression for ninth graders and with illicit drug use, school violence, and sexual abuse for eleventh graders, while having friends was protective for both groups. Additionally, having more than one risk factor imparted an exponential risk for suicide attempts (ninth > eleventh graders). The differences detected are consistent with developmental changes of adolescence and represent important information for identification of at-risk youth. 相似文献

Two competing explanations for higher rates of attempted suicide in women than men were compared. Because childhood sexual abuse is more prevalent in girls than boys, one explanation of higher rates of suicide attempts in women is that it is a direct result of the higher incidence of sexual abuse in girls. Alternatively, higher rates of suicide attempts might result from gender differences in the impact of childhood sexual abuse on suicidal behavior. To compare these theories, data from 1,889 abstinent, substance-dependent patients who completed the Childhood Trauma Questionnaire (CTQ) and who were interviewed about suicide attempts was examined. Scores on each scale of the CTQ were examined as a function of gender and attempter status. Results showed higher rates of suicide attempts in women than in men, higher CTQ scores in women than men, and a higher CTQ score in attempters than nonattempters. However, logistic regression indicated that gender and abuse did not interact to determine attempter status. Thus, the data support the first hypothesis that the greater frequency of suicide attempts in women may be partly attributed to the higher prevalence of childhood sexual abuse in girls. The generalizability of these results to the general population and to other diagnostic groups requires further study. 相似文献

During tip-of-the-tongue (TOT) experiences, phonologically related words have both facilitated and impeded word retrieval.
In the present experiment, we examined whether phonologically related words’ syntactic class (part of speech) is responsible
for these differential effects. Sixty college students saw general knowledge questions whose answers were designated target
words and responded “know,” “don’t know,” or “TOT.” Following “TOT” and “don’t know” responses, the participants saw five
words, one of which was a prime. The primes contained the target’s first syllable and either shared or did not share the target’s
part of speech. Following presentation of the primes, retrieval of the target was attempted again. Different-part-of-speech
primes facilitated resolution of TOT states, whereas same-part-of-speech primes had no effect, relative to phonologically
unrelated words. These results support node structure theory’s most-primed-wins principle and the transmission deficit model
account of TOT states and detail the importance of syntactic class in the selection of words that are candidates for speech
production. 相似文献
