Vervet and grivet monkeys were repeatedly tested eating bar- and circle-shaped cookies. One subject was always injected with lithium immediately after eating cookies with the circle shape and learned to avoid the circular cookies while continuing to eat the bar-shaped cookies. Another subject received similar treatment except that lithium injections were always delayed 30 minutes after access to the circle-shaped cookies. She also acquired a discriminative aversion. Aversion learning was not observed with 60-minute delayed toxicosis or with lithium injections administered unpaired with access to the cookies. The two types of cookies differed only in shape, and conditioning and test sessions were conducted in total darkness to preclude the use of visual cues. Therefore, the avoidance observed in subjects conditioned with immediate and 30-minute delayed toxicosis represents a conditioned aversion to the shape of the cookies as revealed by tactile cues. These findings illustrate that monkeys can learn to select food on the basis of tactile stimuli when such stimuli are conditioned with delayed aversive stimulation. 相似文献

The parents of 3 boys with autism were taught to help their children follow photographic activity schedules depicting a variety of home-living tasks. A multiple baseline across participants showed that the home-based intervention produced increases in children's engagement and social initiations and decreases in disruptive behavior, which were maintained for as long as 10 months. 相似文献

Human subjects responded on two panels. A differential-reinforcement-of-low-rate schedule with a limited-hold contingency operated on Panel A. In Condition 1, responses on Panel B produced a stimulus on the panel that signalled whether reinforcement was available on Panel A. In Condition 2, responses on Panel B briefly illuminated a digital clock. In both conditions, performance on Panel A was very efficient; with few exceptions, Panel A was pressed only when reinforcement was available. Thus, in effect, a fixed-interval schedule operated on Panel B. In Condition 1, a “break-and-run” response pattern occurred on Panel B; with increasing temporal parameters, the duration of the postreinforcement pause on Panel B increased linearly while overall response rate and running rate (calculated by excluding the postreinforcement pauses) remained approximately constant. In Condition 2, the response pattern on Panel B was scalloped; the postreinforcement pause was a negatively accelerated increasing function of schedule value, while overall response rate and running rate were negatively accelerated decreasing functions of schedule value. The performance of subjects in Condition 2, but not in Condition 1, was highly sensitive to the contingencies in operation, and resembled that of other species on the fixed-interval schedule. 相似文献

This mixed-methods study applies Communication Accommodation Theory to explore how liking, power, and sex predict one’s likelihood for using textisms in digital interpersonal interactions. Textisms are digital cues that convey nonverbal meaning and emotion in text communication. The main experiment used a hypothetical texting scenario to manipulate textism amounts (none/many) and participant’s perceived power levels (low/equal/high) during texting interactions to examine the number of textisms participants used in subsequent responses in comparison to the number of textisms they viewed. Primary results show that (1) participants moderately converged to use similar amounts of textisms, and (2) those with low power who viewed many textisms were more likely to use textisms themselves during subsequent responses. Through the examination of adaption behaviors in text messaging, scholars can better understand the contexts in which users will include textisms to intentionally convey nonverbal meaning and emotion in digital communication. 相似文献

无意识目标追求是指个体自动地追求由情境线索激活的目标, 而全然不知目标对自己行为的导向作用。无意识目标追求具有灵活性、抑制性和坚持性。无意识目标追求经由行动的无意识准备和目标价值的自动评估与努力过程实现。积极情绪、内隐态度和人际关系影响无意识目标追求。未来研究需要进一步探讨无意识目标追求的影响因素, 完善无意识目标追求的机制, 探究无意识目标追求结果对个体心理和行为的影响, 提高研究结果的生态效度, 拓展应用研究。 相似文献

Previous studies have examined verbal rather than vocal aspects of irony. The present study considers how vocal features may cue listeners to one form of irony--sarcasm. Speakers were recorded reading sentences in three conditions (nonsarcasm, spontaneous sarcasm, posed sarcasm) with the resulting utterances filtered to remove verbal content. Listeners (n = 127) then rated these filtered utterances on amount of sarcasm. Results indicated that listeners were able to discriminate posed sarcasm from nonsarcasm but not spontaneous sarcasm from nonsarcasm. An analysis of the vocal features of the utterances as determined by perceptual coding indicated that a slower tempo, greater intensity, and a lower pitch level were significant indicators of sarcasm. 相似文献

人类有追求规则、秩序的本能,有秩序的环境是否能提高人们的信任水平呢?本文的具身性研究思路将社会学中抽象的“秩序”具体化为任务操作,以197名大学生为被试,将其分为三组分别完成秩序程度不同的连线任务,然后通过投资博弈任务测量被试信任水平。结果显示,(1)秩序线索影响信任水平,强秩序线索能提高个体信任水平;(2)秩序线索对信任的影响因个体性别不同而表现出差异,秩序线索的差异只影响女性信任水平;不同秩序条件下的男性信任水平不存在显著差异。 相似文献
