Previous research has revealed a strong relationship between mere visual facial cues and body weight. They can be exploited to validly judge the weight of the human body. We tested to what extent observers are able to judge body weight and height on the basis of same-ethnicity and different-ethnicity faces. Caucasian and Asian observers saw Caucasian and Asian faces and estimated the person’s weight and height – merely on the basis of greyscale photographs of the face. These height and weight estimates were influenced by ethnocentric specifics of familiar face proportion and face–body relationship. Own-ethnicity weight estimations showed higher accuracy than foreign-ethnicity estimations. Observers ignored the changed base-rate for weight of other-culture faces in a culture-egocentric fashion. Height judgments, in contrast, reflect a higher degree of sophistication. A bias toward the own, familiar body proportion was visible here, especially for Japanese observers—however, the height judgments showed that observers were able to incorporate the other-ethnicity height proportion to some extent. 相似文献

Using a generalized conception of experience, from which all features characteristic for higher animals (such as consciousness and thought) have been removed, allowed relating experience to adaptive processes in lower organisms. The temporal vector character of every current experience, containing as well memories of past experiences as intentions for future activities, can then be found in the adaptive response of cyanobacteria to alterations in phosphate supply, particularly in energetic manifestations of this phenomenon. A possible analogy between adaptive events as the “atomic units” of physiological adaptation and Whitehead's actual occasion of experience is discussed. 相似文献

In this study we quantify for the first time electrophysiological components associated with incorporating long-term semantic knowledge with visuo-spatial information using two variants of a traditional matrix patterns task. Results indicated that the matrix task with greater semantic content was associated with enhanced accuracy and RTs in a change-detection paradigm; this was also associated with increased P300 and N400 components as well as a sustained negative slow wave (NSW). In contrast, processing of the low semantic stimuli was associated with an increased N200 and a reduction in the P300. These findings suggest that semantic content can aid in reducing early visual processing of information and subsequent memory load by unitizing complex patterns into familiar forms. The N400/NSW may be associated with the requirements for maintaining visuo-spatial information about semantic forms such as orientation and relative location. Evidence for individual differences in semantic elaboration strategies used by participants is also discussed. 相似文献

There is some evidence that patients with bipolar disorder recall more overgeneral than specific autobiographical memories, a pattern widely reported in depression. However, there are also theoretical arguments (Barnard, Watkins, & Ramponi, 2006) suggesting that experiential processing should predominate during mania/hypomania, with an associated prediction of an increase in specific rather than overgeneral memories. This hypothesis was explicitly tested using the Autobiographical Memory Test (AMT). The specificity and speed of autobiographical recollection was compared for those with high or low levels of hypomanic personality as indexed by the Hypomanic Personality Scale (HPS). High HPS scorers recalled specific autobiographical memories in response to unpleasant cues more frequently and faster than low scorers. These results provide partial support for the hypothesis, but only for unpleasant cues. 相似文献

ABSTRACTSelf-referential processing has been proven to be effective in improving source memory. However, it is unclear whether different types of source information would be consistently enhanced when an item is self-referentially processed. In two experiments, the authors examined the influence of the self (compared with other-referencing and semantic processing) as well as learning intention (incidental/intentional learning) on memory for two types of source information (spatial location and colour) that differ in the amount of cognitive resources they require to be encoded in memory. Results show that self-referencing has enhanced memory for spatial location of words whatever this information is learned intentionally or incidentally, whereas it cannot facilitate memory for the colour of words under the intentional learning condition, nor can it under the incidental condition. These findings suggest that self-referential processing is beneficial in memory improvement but not all-powerful, a source self-reference effect is subject to source information type. 相似文献

The testing effect is the finding that taking a review test enhances performance on a final test relative to restudying the material. The present experiment investigated transfer-appropriate processing in the testing effect using semantic and orthographic cues to evoke conceptual and data-driven processing, respectively. After a study phase, subjects either restudied the material or took a cued-recall test consisting of half semantic and half orthographic cues in which the correct response was given as feedback. A final, cued-recall test consisted of the identical cue, or a new cue that was of the same type or different type of cue (semantic/orthographic or orthographic/semantic) as that used for that target in the review test. Testing enhanced memory in all conditions. When the review cues and final-test cues were identical, final recall was higher for semantic than orthographic cues. Consistent with test-based transfer-appropriate processing, memory performance improved as the review and final cues became more similar. These results suggest that the testing effect could potentially be caused by the episodic retrieval processes in a final memory test overlapping more with the episodic retrieval processes in a review test than with the encoding operations performed during restudy. 相似文献

The authors examined the effect that being at risk for developing an eating disorder has on the lexical processing of words related to fat and words not related to fat. Individuals (n = 17) at risk for developing an eating disorder were compared with controls (n = 31) using a lexical decision task in which fat-related words (e.g., large), unrelated words (e.g., fair), neutral words (e.g., post), and pseudowords (e.g., flirp) were given. The results revealed an expected Group x Stimuli interaction for reaction times indicating that at-risk individuals were significantly faster at processing fat-related words than words unrelated to fat. The authors discuss these results within the context of how fat-related stimuli are processed in at-risk individuals and how models of information processing can aid in the interpretation and understanding of eating disorders. 相似文献

The authors investigated whether and, if so, how velocity information is used to control predictive manual pointing movements and saccades. Participants (N = 6) intercepted an occluded moving target as if it were still visible. They kept their eyes fixated while the target moved. The target traveled over a fixed distance and changed its velocity on the way. The presentation time of the final velocity was varied. Both the eye and the hand overshot the slow target and undershot the fast target, particularly when the duration of the final velocity was short. Thus, responses were biased in the direction of the target's initial velocity. The error seemed to arise because participants did not take their latency into account when aiming at the target. Instead, they strategically aimed farther ahead when the target was fast. Amplitude was also more related to the position of velocity change than to final velocity duration. Both findings suggest that target velocity is not extrapolated but that individuals add an increment to the position of velocity change. 相似文献

In the visuomotor mental rotation (VMR) task, participants point to a location that deviates from a visual cue by a predetermined angle. This task elicits longer reaction times (RT) relative to tasks wherein the visual cue is spatially compatible with the movement goal. The authors previously reported that visuomotor transformations are faster and more efficient when VMR responses elicit a degree of dimensional overlap (i.e., 0° and 5°) or when the transformation involves a perceptually familiar angle (i.e., 90° or 180°; K. A. Neely & M. Heath, 2010b). One caveat to this finding is that standard and VMR responses were completed in separate blocks of trials. Thus, between-task differences not only reflect the temporal demands of the visuomotor transformations, but also reflect the temporal cost of response inhibition. The goal of this study was to isolate the time cost of visuomotor transformations in the VMR task. The results demonstrated that visuomotor transformations are more efficient and effective when the response entails a degree of dimensional overlap between target and response (i.e., when the angular disparity between the responses is small) or when the transformation angle is perceptually familiar. 相似文献
