For many decisions we make, we are more likely to receive feedback about some outcomes than about others, and thus we must operate under conditions of asymmetric partial feedback. In this paper, we examine the effects of asymmetric partial feedback on decision making across three experiments. Experiment 1 examines the effects of four partial feedback schedules on decision making in a single‐attribute auditory detection task. Experiment 2 examines these same schedules in the context of a simulated experiment in which virtual participants perform a multi‐attribute choice task. Experiment 3 then examines effects of one partial feedback schedule representative of a real‐world decision‐making domain (personnel selection) using an ecologically informed multi‐attribute choice task. All three experiments reveal that asymmetric partial feedback primarily impacts on response‐bias, a parameter of signal detection theory. These findings can be explained in terms of decision makers' attempts to maximize accuracy and the fact that shifts in response‐bias will, under partial feedback, produce misleading impressions of greater accuracy.

Three experiments were conducted to determine whether an object-based correspondence effect for torch (flashlight) stimuli reported by Pellicano et al. [(2010). Simon-like and functional affordance effects with tools: The effects of object perceptual discrimination and object action state. Quarterly Journal of Experimental Psychology, 63, 2190–2201] is due to a grasping affordance provided by the handle or asymmetry of feature markings on the torch. In Experiment 1 the stimuli were the same as those from Pellicano et al.'s Experiment 2, whereas in Experiments 2 and 3 the stimuli were modified versions with the graspable handle removed. Participants in all experiments performed upright/inverted orientation judgements on the torch stimuli. The results of Experiment 1 replicated those of Pellicano et al.: A small but significant object-based correspondence effect was evident, mainly when the torch was in an active state. With the handle of the torch removed in Experiment 2, making the barrel markings more asymmetric in the display, the correspondence effect was larger. Experiment 3 directly demonstrated an effect of barrel-marking asymmetry on the correspondence effect: When only the half of the markings nearest the light end of the torch was included, the correspondence effect reversed to favour the light end. The results are in agreement with a visual feature-asymmetry account and are difficult to reconcile with a grasping-affordance account. 相似文献

Elite dancers perform highly skilled and consistent movements. These movements require effective regulation of the intrinsic and extrinsic forces acting within and on the body. Customized, compliant floors typically used in dance are assumed to enhance dance performance and reduce injury risk by dampening ground reaction forces during tasks such as landings. As floor compliance can affect the extrinsic forces applied to the body, secondary effects of floor properties may be observed in the movement consistency or kinematic variability exhibited during dance performance. The aim of this study was to investigate the effects of floor mechanical properties on lower extremity kinematic variability in dancers performing landing tasks. A vector coding technique was used to analyze sagittal plane knee and ankle joint kinematic variability, in a cohort of 12 pre-professional dancers, through discrete phases of drop landings from a height of 0.2 m. No effect on kinematic variability was observed between floors, indicating that dancers could accommodate the changing extrinsic floor conditions. Future research may consider repeat analysis under more dynamic task constraints with a less experienced cohort. However, knee/ankle joint kinematic variability was observed to increase late in the landing phase which was predominantly comprised of knee flexion coupled with the terminal range of ankle dorsiflexion. These findings may be the result of greater neural input late in the landing phase as opposed to the suggested passive mechanical interaction of the foot and ankle complex at initial contact with a floor. Analysis of joint coordination in discrete movement phases may be of benefit in identifying intrinsic sources of variability in dynamic tasks that involve multiple movement phases. 相似文献

We compared effects of adjacent (e.g. atricle-ARTICLE) and non-adjacent (e.g. actirle-ARTICLE) transposed-letter (TL) primes in an event-related potential (ERP) study using the sandwich priming technique. TL priming was measured relative to the standard double-substitution condition. We found significantly stronger priming effects for adjacent transpositions than non-adjacent transpositions (with two intervening letters) in behavioural responses (lexical decision latencies), and the adjacent priming effects emerged earlier in the ERP signal, at around 200-ms post-target onset. Non-adjacent priming effects emerged about 50 ms later and were short-lived, being significant only in the 250- to 300-ms time-window. Adjacent transpositions on the other hand continued to produce priming in the N400 time-window (300- to 500-ms post-target onset). This qualitatively different pattern of priming effects for adjacent and non-adjacent transpositions is discussed in the light of different accounts of letter transposition effects and the utility of drawing a distinction between positional flexibility and positional noise. 相似文献

Orientation perception in rhesus monkeys (<Emphasis Type="Italic">Macaca mulatta</Emphasis>) 总被引:1,自引:1,他引:0

It was previously demonstrated that monkeys divide the orientation continuum into cardinal and oblique categories. However, it is still unclear how monkeys perceive within-category orientations. To better understand monkeys' perception of orientation, two experiments were conducted using five monkeys. In experiment 1, they were trained to identify either one cardinal or one oblique target orientation out of six orientations. The results showed that they readily identified the cardinal target whether it was oriented horizontally or vertically. However, a longer training period was needed to identify the oblique target orientation regardless of its degree and direction of tilt. In experiment 2, the same monkeys were trained to identify two-oblique target orientations out of six orientations. These orientations were paired, either sharing the degree of tilt, direction of tilt, or neither property. The results showed that the monkeys readily identified oblique orientations when they had either the same degree or direction of tilt. However, when the target orientations had neither the same degree nor direction of tilt, the animals had difficulty in identifying them. In summary, horizontal and vertical orientations are individually processed, indicating that monkeys do not have a category for cardinal orientation, but they may recognize cardinal orientations as non-obliques. In addition, monkeys efficiently abstract either the degree or the direction of tilt from oblique orientations, but they have difficulty combining these features to identify an oblique orientation. Thus, not all orientations within the oblique category are equally perceived. 相似文献

疼痛对心理的影响及其机制 总被引:1,自引:0,他引:1
疼痛对个体的认知、情绪等心理过程有消极影响。疼痛会干扰个体的选择性和持续性注意, 损害其记忆功能。长期疼痛还会诱发焦虑和抑郁等消极情绪。目前疼痛的机制主要有闸门控制理论和神经网络理论, 分别从脊髓水平和大脑水平解释疼痛与心理的交互作用。大脑对疼痛信息的编码方式包括特异化理论、模块化理论和中枢整合机制学说。未来研究应注意实验室研究与临床研究的差异, 区分急、慢性疼痛的特有机制, 进一步探讨疼痛理论的合理性。 相似文献

已知肥大细胞作为免疫细胞在过敏反应和炎性疾病中发挥重要作用。肥大细胞在中枢亦有表达, 但对其作用了解不足。新近的研究发现中枢肥大细胞在脑功能和行为调节中发挥重要的内源性平衡作用。一方面, 中枢肥大细胞在维持相关脑区发育, 正常神经活动, 以及动机, 情绪和认知等多种行为中发挥保护性作用, 各种应激条件诱导的中枢肥大细胞表达和活动改变参与脑和行为的适应性反应过程。另一方面, 中枢肥大细胞过度激活或者过度抑制都可导致脑功能和行为异常, 并参与某些免疫相关心身疾病的病理过程。体外神经解剖学和功能学研究证据提示中枢肥大细胞与神经系统间存在结构性和功能性相互作用网络。肥大细胞和神经组织间通过形成类似突触的结构性联系直接影响相邻细胞的活动。肥大细胞还可以通过脱颗粒释放多种生物活性介质调节神经活动, 同时表达多种受体接受脑内免疫性和神经性分子调节。但是目前对于中枢肥大细胞-神经系统相互作用的认识主要基于体外研究, 其在脑内相互作用方式及其与特定脑区功能和行为表型的关系所知甚少, 开展相关研究可以为认识脑与行为的神经免疫调节机制提供新的视角。 相似文献
