研究以眼动追踪的方法探讨线索聚焦性对前瞻记忆(prospective memory, PM)加工过程的影响。实验1中,28名被试完成了线索聚焦和非聚焦两类PM眼动追踪任务。结果发现,个体在聚焦和非聚焦两类PM任务意向维持、意向提取阶段上均表现出不同的眼动加工特征。实验2中,研究进一步对线索聚焦和非聚焦两个PM任务中PM线索词重复次数进行平衡,并重复了实验1的研究结果,说明实验1所观测到的效应不是PM线索词重复造成的混淆,线索聚焦性影响PM的意向维持、意向提取过程,研究结果支持多重加工理论。 相似文献

Height is an important concern in human mate choices. Prior research indicates that people who live in areas with abundant resources differ from those who live in areas with scarce resources regarding height preferences. Based on a health‐maximizing principle, we propose a resource availability account for such differences. Compared with women's height preferences, men's height preferences are hypothesized to be more dependent on either financial or caloric resource availability. Specifically, taller females would be more preferred by males who are poor in resources than those who are rich in resources. Results from three studies supported these hypotheses. In Study 1, men from remote areas of China who had lower family income preferred taller women more than those from eastern China who had higher family income. In Study 2, men who were financially dissatisfied preferred taller women more than those who were financially satisfied. In Study 3, men with low caloric status preferred taller women more than men with high caloric status. In addition, women's height preferences in Studies 1, 2 and 3 were less determined by resource availability. These findings suggest that height preferences are changeable, depending on financial or caloric status. 相似文献

The aim of this study was to examine whether dispositional optimism and induced optimism are associated with an attentional bias for positive stimuli. Fifty-six healthy participants performed an eye-tracking task twice, while their gazing time at faces displaying joy, anger, pain, or a neutral expression was measured. Participants scoring high on dispositional optimism tended to gaze longer at joy faces during the first face-presentation trial compared to participants scoring lower on optimism, and this correlation became significant during the second face-presentation trial. In between the two presentations, participants received either an optimism manipulation or a control manipulation. There was no effect of type of manipulation on gazing behavior but post hoc analyses demonstrated that participants showing an increase in state optimism displayed a significant decrease in gaze duration for anger faces and a nearly significant increase in gaze duration for joy faces. 相似文献

Behavioural and neuroimaging studies provide evidence of automatic activation of phonology (e.g., covert speech) during the recognition of lexical stimuli. Implicit processing of phonological information was investigated in a kinematic study of semantic categorisation of pictures (session A) or words (session B). Participants clicked one of two items (target and distractor) based on their semantic congruency (artefact or natural) with a cued-word. Phonological similarity between cued-word and distractor was varied. The presence of the phonological distractor produced trajectories with greater curvature towards the competing semantic category than did the presence of a distractor not phonologically related. This suggests that the semantic categorisation of pictorial and lexical stimuli is influenced by the automatic activation of phonological information. Trajectories’ curvature reveals competition between partially activated phonological and semantic representations suggesting that phonological codes involved in linguistic processing influence the dynamic competition underlying the semantic categorisation of lexical and pictorial. 相似文献

Research shows that driver factors, particularly driver distraction, are the most common cause of traffic accidents. Among various visual distractions, objects such as advertisements that are commonly prevailing elements at the roadside, represent an important external distractor that may affect driving performance. Research findings on the influence that roadside signs or advertisements have on driver’s attention focus are not consistent. Therefore, with the application of eye-tracking technology, this research was designed to test several assumptions regarding drivers’ detection and perception of roadside elements. Seventeen volunteer participants, 19–76 years old, performed ten kilometres of urban driving, in which they were visually challenged with 56 traffic signs and 31 advertisements. It was found that drivers’ age is not associated with the number of roadside objects detected. Those drivers who detected more traffic signs were also more attentive to visual advertisements. Furthermore, a positive and large effect size between the number of detected street-level and raised-level advertisements was also found. 相似文献

Recently, there has been increased interest in decisions‐from‐experience (where decision makers learn from observing the outcomes of previous choices), which provide valuable insights into the learning and preference construction processes underlying many daily decisions. Several process models have been developed to capture these processes, and while such models often fit the data well, many assume that the decision maker is a vigilant observer, processing each outcome. In two studies, we provide a critical test of this assumption using eye tracking to record directed visual attention when participants choose repeatedly among two options, each time being shown the outcome for their chosen option and for the foregone option. Consistently, we find that the vigilance assumption is not supported, with decision makers often not attending to outcome information. Moreover, (in)attention to outcomes is predictable, with vigilance decreasing as more choices are made, and being greater for obtained than for foregone outcomes, and when options deliver only gains as opposed to losses or a mixture of gains and losses. Furthermore, we find that this variation in attentional allocation plays a central role in the apparent indecisiveness (inconsistency) in choice, with increased attention to foregone outcomes predicting switches to that option on the next choice. Together, these findings highlight the value of eye tracking in investigations of decisions‐from‐experience, providing novel insight into the cognitive processes underlying them.

“I can see it in your eyes”: Biased Processing and Increased Arousal in Dishonest Responses

According to self‐maintenance theory, people notice their dishonest acts and thus experience ethical dissonance between their misconduct and their positive moral self. In this view, dishonesty is facilitated by justifications that redefine moral boundaries. By contrast, the bounded ethicality approach suggests that biased perception prevents people from becoming aware of their dishonesty. We tested the key process assumptions behind these accounts using pupillary responses and fixation data and found physiological evidence for both kinds of mechanisms. In particular, physiological arousal increased at the initial stage of cheating responses. This suggests that people are on some level aware of their wrongdoings. At the same time, however, we found attentional biases that can reduce the likelihood for detecting potentially disadvantageous information. We suggest that dishonest acts come at the internal cost of increased tension, which people aim to avoid by pre‐emptive biased processing as well as post hoc justifications.

Humans have the ability to chunk together information from nonadjacent serial positions in sequential patterns. For example,
human subjects can extrapolate the pattern, A-M-B-N-C-O-D-P-E-..., to find the missing element, Q, by sorting pattern elements
into two component interleaved subpatterns: A-B-C-D-E and M-N-O-P-... Two experiments investigated the ability of rats to
reorganize pattern elements from nonadjacent serial positions into chunks not presented by the experimenter. Rats learned
either a structured or unstructured sequence interleaved with elements of a repeating sequence (experiment 1) or an alternation
sequence (experiment 2). In both experiments, rats learned the interleaved subpatterns at different rates. Acquisition rate
was correlated with the structural properties of component subpatterns and the nature of the rules required to describe the
interleaved subpatterns. The results indicate that rats are sensitive to the organization of nonadjacent elements in serial
patterns and that they can detect and sort structural relationships in interleaved patterns.

Pigeons were trained to peck the center key (lighted white) of three response keys to turn off the center keylight and to light one of the side keys with a red keylight and the other side key with a green keylight. Five responses (fixed-ratio component) on either side key relighted the center key. Food was delivered following 10 fixed-ratio components on the red key if 1.5 mg/kg phencyclidine had been given before the session. The position of the red and green keylights on the side keys varied randomly each time they were lighted by a peck on the center key. Subsequently, increasing doses of phencyclidine, barbital, amobarbital, phenobarbital, methaqualone, methyprylon, diazepam, oxazepam, and d-amphetamine were substituted for the training dose of phencyclidine, using a cumulative dosing procedure. At low doses of the sedative hypnotics, birds pecked the keylight color associated with saline. At higher doses, birds pecked both key colors. At the highest doses of pentobarbital and amobarbital, some birds responded almost exclusively On he color associated with phencyclidine. When responding on keys of both colors occurred following administration of phencyclidine or other sedative hypnotics, this responding was controlled by key position rather than by key color. 相似文献

The present study investigated a discrete-trials, operant tracking and a descending-series procedure for the determination of hearing levels with profoundly retarded individuals. These individuals were previously diagnosed as untestable. Following stimulus-control training with errorless discrimination procedures, hearing levels for each individual were examined with both procedures. For P-1 and P-2, the operant tracking procedure was administered following a descending-series procedure. Both were observed to “track” their own hearing levels. For P-3, the operant tracking procedure was administered first, followed by the descending-series procedure. Although P-3 also “tracked” her own hearing level, more variable responding was observed. Nonetheless, the operant tracking procedure proved quite workable and may provide for improved hearing testing with “difficult-to-test” individuals. 相似文献
