Individuals with obsessive-compulsive disorder describe “not just right experiences” as a constant uncomfortable feeling of imperfection toward sensory stimuli. This study examined the relation between “not just right experiences,” obsessive-compulsive disorder and sensory over-responsivity symptoms. Sixty college students participated in the in vivo “not just right experiences” assessment. This included four tasks for which participants rated pre-task discomfort, post-task discomfort, and urge to counteract auditory, visual, and tactile stimuli. “Not just right experiences” scores significantly correlated with obsessive-compulsive disorder scores. Tactile, auditory, and visual sensory over-responsivity scores were correlated with specific “not just right experiences” scores. Sensory over-responsivity is rarely addressed in obsessive-compulsive disorder while it contributes to symptomatology and participation. 相似文献

Consider an experiment in which a subject guesses repeatedly at a randomly chosen target on a continuum. To guarantee a positive probability of success, the continuum is partitioned into a finite but large number of segments. The subject is given directional feedback. General guessing strategies are characterized, and an optimal strategy is identified. The hypothesis that the subject's performance can be explained by chance alone is of interest in such experiments. A test is developed based on comparing the subject's performance to expected performance using the optimal strategy. A skill-scoring procedure is developed for assessing a subject's performance in light of the strategy used, and a test based on skill-scoring is advanced.Research by the first author is supported in part by the Air Force Office of Scientific Research under grant AFOSR 77-3180.The authors wish to thank the referees for remarks that led to improvements in both content and clarity. 相似文献

The delay-reduction hypothesis of conditioned reinforcement and punishment: Observing behavior 总被引:7,自引:6,他引:1 下载免费PDF全文
Pigeons responded in an observing-response procedure in which three fixed-interval components alternated. Pecking one response key produced food reinforcement according to a mixed schedule. Pecking the second (observing) key occasionally replaced the mixed-schedule stimulus with the stimulus correlated with the fixed-interval component then in effect. In Experiment 1, observing was best maintained by stimuli correlated with a reduction in mean time to reinforcement. That finding was consistent with the conditioned-reinforcement hypothesis of observing behavior. However, low rates of observing were also maintained by stimuli not representing delay reduction. Experiment 2 assessed the role of sensory reinforcement. It showed that response rate was higher when maintained by stimuli uncorrelated with reinforcement delay than when the stimuli were correlated with a delay increase. This latter result supports a symmetrical version of the conditioned-reinforcement hypothesis that requires suppression by stimuli correlated with an increase in time to reinforcement. The results were inconsistent with hypotheses stressing the reinforcing potency of uncertainty reduction. 相似文献

The Triangular Constant Method was designed for the measurement of discriminability between sensory stimuli. Its original model assumes a steady excitatory detection state. The purpose of this paper is to elaborate on the consequences of assuming a variable excitatory state and to formulate the concomitant model. 相似文献

Odor Semantics and Visual Cues: What We Smell Impacts Where We Look,What We Remember,and What We Want to Buy 下载免费PDF全文
The current research uses eye‐tracking technology in a consumer context to explore the interactive effects of olfactory and visual cues on consumers' eye gaze patterns. We manipulate the semantic correspondence between pictorial objects depicted in print advertisements and odors smelled (or not) while looking at the ads. The results indicate that smelling a scent that shares learned semantic associations with an object in the advertisement diverts consumers' eye gazes to the semantically related object in the ad, with positive downstream effects on advertising recall and purchase intent. This is the first study we are aware of demonstrating multisensory integration of odors and pictures on consumer eye gaze patterns with clear implications for consumer choice.

One hundred and forty-six participants (age range = 20-80) completed a battery of tests designed to measure visual acuity, processing speed, inhibition, episodic memory and false memory. The relations between visual acuity and general cognitive ability, as well as between visual acuity and the indicators of this construct, were evaluated with structural equation modeling. The measurement model confirmed that the indicators of the individual cognitive abilities could be grouped into a general cognitive functioning factor. However, the relation between episodic and false memory was not completely explained by the shared association with this general factor. Furthermore, visual acuity predicted approximately half of the age-related variance in the general cognition factor. Also, the proportion of age-related variance shared with vision was highest in inhibition and lowest in false memory. The results are discussed in the light of common cause accounts of cognitive aging. 相似文献

We compared the effects of two treatments, noncontingent reinforcement (NCR) and sensory extinction (EXT), on the self-injurious behavior (SIB) exhibited by 3 individuals with developmental disabilities. Results of a functional analysis indicated that their SIB was not maintained by social reinforcement, as indicated by undifferentiated responding across assessment conditions or higher rates of responding in the alone condition. Prior to treatment, leisure probes were conducted to identify highly preferred items for use in the NCR condition, and equipment probes were conducted to identify devices that produced the greatest behavioral suppression for use in the EXT condition. Following baseline, treatment was implemented in a multiple baseline across subjects design, and the effects of NCR and EXT were compared in a multielement format. During NCR sessions, participants had continuous access to a highly preferred item. During EXT sessions, participants wore equipment (gloves or protective sleeves) that seemed to attenuate stimulation directly produced by their SIB, while still allowing the behavior to occur. Results indicated that both procedures were effective in reducing SIB, although NCR was associated with either more rapid or greater overall response suppression. 相似文献

William R. Ferrell's paper is a reply to our article "Calibration of sensory and cognitive judgments: Two different accounts", 1993, 34, 135–148 in this journal. Ferrell's critique centres around three issues: (1) The model of sensory discrimination proposed by Björkman et al. (1993) and discussed in Winman and Juslin (1993) is not new, (2) this model does not predict underconfidence, (3) there is no need for separate models of calibration of sensory and cognitive judgments. Below we respond to each of the three issues raised by Ferrell. 相似文献

本研究以味觉和痛觉两种感觉通道的体验为对象,探讨预期效价和预期信心如何影响知觉体验的结果及其作用机制。通过基于味觉和痛觉的两个实验,发现预期会影响即时知觉体验,并且预期信心在其中起到调节作用——对预期充满信心时,即时体验和对结果的预期保持一致,预期越积极即时体验越好,预期越消极即时体验越差;而对预期缺乏信心时,即时体验和预期之间呈现背离趋势,预期越积极即时体验越差,预期越消极即时体验则越好。研究结果阐明了预期影响即时体验的机制,对我们理解身心关系也具有重要的理论意义。 相似文献

We compared the effects of escape extinction (EE) plus noncontingent reinforcement (NCR) with sensory integration therapy as treatment for the feeding problems of 2 children. Results indicated that EE plus NCR was more effective in increasing acceptance, decreasing inappropriate behavior, and increasing amount consumed relative to sensory integration for both children. The results are discussed in terms of the challenges of evaluating sensory‐integration‐based treatments, and the reasons why component analyses of multicomponent treatments like sensory integration are important. 相似文献
