Teasing is ambiguous. Although the literal content of a tease is, by definition, negative, seldom do teasers intend for their tease to be taken literally. Toward this aim, teasers often attempt to mitigate the negative surface content of the tease by communicating via gesture, facial expression, or tone of voice that they are "just kidding." The research presented here suggests that such attempts often fall on deaf ears. Despite teasers' attempts to mitigate the tease, targets are often unaware of--and unmoved by--the teaser's benign intentions. As a result, teasers and targets systematically differ in their perceptions of teasing: Although it is often seen as innocent and playful by the teaser, it tends to be construed as considerably more malicious by the target. 相似文献

This study investigated the possibility of promoting fluency of performance, i.e., a performance independent of caregiver's guidance and without serious interruptions, during morning dressing in two adults with multiple disabilities. The intervention program relied on the use of assistive technology including optic and pressure sensors to monitor the participants' task responding and tape players to present preferred stimuli in relation to such responding, as well as messages of encouragement. Analysis showed that the intervention program was effective with both participants. In fact, they became capable of performing the dressing sequence with only occasional guidance from research assistants, and the time they required for dressing dropped significantly from baseline levels. Implications of the results are discussed. 相似文献

When a line is presented in the vicinity of a recent luminance change (peripheral cue), it is perceived to be drawn over time away from its "cued" end even though the line is actually presented all at once. This study was designed to determine whether attention, exogenously attracted to the cue, would come under the exogenous control of this illusory motion and follow the drawing motion from the cued end to its terminus. Each trial began with the display of four small squares at the corners of an imaginary square centered about fixation. On the critical trials, one of the four squares brightened briefly, after which a horizontal line was presented joining either the two upper or the two lower squares. Shortly thereafter, the distribution of attention was determined by asking the observer to indicate the nature of a change that was equally likely to occur to one of the squares. Responses to targets presented at a noncued location that was at the end of an illusorily drawn line were as fast as those to targets at the cued location and were much faster than those to targets at the remaining noncued locations. This pattern was not shown when the line preceded the cue, strongly suggesting that attention follows the motion in this illusion. 相似文献

We addressed several questions regarding the relation of anxiety sensitivity to anxious symptoms among 47 youth psychiatric inpatients (18 boys, 29 girls), ages 9–17 (M = 14.23, SD = 1.89). Participants completed measures of anxiety sensitivity, anxious and depressive symptoms, trait anxiety, and positive and negative affect; chart diagnoses were available. Consistent with hypotheses, we found that (a) anxiety sensitivity was associated with anxious symptoms, even controlling for trait anxiety and depressive symptoms; and (b) anxiety sensitivity displayed symptom specificity to anxious versus depressive symptoms (i.e., was associated with anxiety controlling for depression but not with depression controlling for anxiety). Furthermore, regarding factors of anxiety sensitivity, we obtained mixed support for our prediction that phrenophobia would be associated with both depression and anxiety, whereas fear of physical arousal would be associated with anxiety but not depression. Implications for the construct validity of anxiety sensitivity were discussed. 相似文献

In an item-method directed forgetting task, attentional resources are withdrawn from forget item processing (e.g., Taylor & Fawcett in Attention, Perception, & Psychophysics, 73, 1790–1814, 2011). Taylor and Hamm (Attention, Perception, & Psychophysics, 78, 168–186, 2016) demonstrated that there is no corresponding increase in the proclivity for exogenous attention to be captured following a forget instruction. This means either that the attentional resources withdrawn from the forget item are reallocated immediately (and therefore not especially vulnerable to capture) or that it is not exogenous attention that is withdrawn. Given that endogenous attention is distinct from exogenous attention, we therefore extended the Taylor and Hamm study by using endogenous orienting rather than exogenous orienting. Words appeared individually in a peripheral location (Exp. 1) or in a central location (Exp. 2), followed by an instruction to either remember or forget. After a short (50-ms) or long (250-ms) interstimulus interval (ISI), a central cue (80% accurate) directed participants to allocate their attention to the left or right. This was followed by a discrimination target that appeared at a 1,000-ms cue–target stimulus onset asynchrony. A subsequent yes–no recognition test assessed memory for all study items. In both experiments, we observed better recognition of remember words than forget words—a directed forgetting effect. We also found a cueing effect, revealed as faster reaction times to discriminate cued targets than to discriminate uncued targets. There was not, however, an effect of memory instruction (and/or instruction–cue ISI) on the magnitude of this cueing effect. Thus, neither exogenous attention nor endogenous attention remains in an unengaged state following an instruction to forget. 相似文献

This study explored the important mediating role of personal religious variables and God concept in the use of religious coping in threat, loss, and challenge situations. One hundred and twenty-nine undergraduates completed questionnaires which included a God concept adjective checklist (Schaefer and Gorsuch 1992), a stressor scenario (Bjorck and Cohen 1993), and a measure of religious coping adapted from the BAV model (Gorsuch 1988). Results suggest that personal variables such as God concept and perception of others' beliefs played important mediating roles in religious coping in stressor situations. The relationship between coping style and stressor scenario was not entirely state-dependent, but influenced by personal variables. Strong relationships existed among God concept, the importance individuals placed on their religious and spiritual lives, and participation in religious activities. 相似文献

Two of the possible mechanisms that have been put forward to explain precuing effects are signal enhancement and uncertainty reduction. Signal enhancement leads to processing advantages for valid information because the signal at the known input channel is enhanced, whereas uncertainty reduction allows observers to ignore confusing distractor items in a display. Both mechanisms have been reported to be involved in location precuing, but it is still unclear which of these two mechanisms is responsible for color cuing effects. Two experiments are reported in which expectancy for a certain color in a single-item display was created. Targetswere presented briefly and were masked. If color cues produce signal enhancement, then a color cuing effect should result. If color cues only allow uncertainty reduction, however, there should be no color cuing effect because there are no distractors in single-item displays. The results of both experiments favor uncertainty reduction as the mechanism behind color cuing, because no signs of signal enhancement-based cuing effects were observed. 相似文献

Prior to the initiation of spontaneous movement, evoked potentials can be seen to precede awareness of the impending movement by several hundreds of milliseconds, meaning that this recorded neural activity is the result of unconscious processing. This study investigates the neural representations of impending movement with and without awareness. Specifically, the relationship between awareness and 'idling' cortical oscillations in the beta range (18-24Hz) was assessed. It was found that, in situations where there was awareness of the impending movement, pre-movement evoked potentials were associated with a decrease in beta range oscillations. In contrast, when awareness of the impending movement was not present, the onset of the pre-movement potential was associated with tonic levels of beta range oscillations. A model is considered where by distributed neural activity remains outside of conscious awareness through the persistence of tonic slow wave cortical oscillations. 相似文献

In this study we examined the evocative and abative effects of an establishing operation on challenging behavior during classroom instruction for a student with severe disabilities including autism. A prior functional analysis indicated that his challenging behavior was maintained by access to preferred snack items. During classroom instructional sessions these snack items were visible but not available to the student. In other words challenging behavior was placed on extinction during instruction. Immediately prior to instructional sessions the student received either access to snack items or did not receive access to snacks. Access versus no access to snacks prior to instruction was systematically controlled using a multi‐element design. Results demonstrated higher levels of challenging behavior during instruction when the student did not have access to snacks prior to instruction. Very little challenging behavior occurred during instructional sessions when the student had prior access to snacks. Implications for considering the evocative and abative effects of establishing operations when implementing operant extinction in applied settings are discussed.

Theory and research suggest that Internet identification may account for some of the gender divide in Internet use. Internet identification is a type of domain identification, and is inherently bound with images of those who use the Internet, a domain traditionally conceived as masculine. Combining the "draw an Internet user" test with an Internet identification scale, this study tests two hypotheses: participants drawing gender-concordant images will (i) identify with and (ii) use the Internet more than those drawing gender-discordant images. Participants were 371 students (121 males, 250 females) from three universities in the United Kingdom and Australia. The need to challenge masculinized images of the Internet is discussed. 相似文献
