The effect of height in the picture plane on the remembered location of ascending or descending targets was examined. Consistent with previous research, memory was displaced forward in the direction of motion. The magnitude of forward displacement was larger for targets low in the picture plane than for targets high in the picture plane, and this was observed with ascending motion and with descending motion. This pattern is consistent with the hypothesis that memory for the location of ascending or descending targets is biased by the effects of implied gravitational attraction on the velocity of those targets, and some implications of such a bias for issues in mental representation are noted. 相似文献

Cognitive representation of linear motion: Possible direction and gravity effects in judged displacement 总被引:1,自引:0,他引:1
Timothy L. Hubbard 《Memory & cognition》1990,18(3):299-309
The judged vanishing point of a target undergoing apparent motion in a horizontal, vertical, or oblique direction was examined. In Experiment 1, subjects indicated the vanishing point by positioning a crosshair. Judged vanishing point was displaced forward in the direction of motion, with the magnitude of displacement being largest for horizontal motion, intermediate for oblique motion, and smallest for vertical motion. In addition, the magnitude of displacement increased with faster apparent velocities. In Experiment 2, subjects judged whether a stationary probe presented after the moving target vanished was at the same location where the moving target vanished. Probes were located along the axis of motion, and probes located beyond the vanishing point evidenced a higher probability of a same response than did probes behind the vanishing point. In Experiment 3, subjects judged whether a stationary probe presented after the moving target vanished was located on a straight-line extension of the path of motion of the moving target. Probes below the path of motion evidenced a higher probability of a same response than did probes above the path of motion for horizontal and ascending oblique motion; probes above the path of motion evidenced a higher probability for a same response than did probes below the path of motion for descending oblique motion. Overall, the pattern of results suggests that the magnitude of displacement increases as proximity to a horizontal axis increases, and that in some conditions there may be a component analogous to a gravitational influence incorporated into the mental representation. 相似文献

Children (N = 404), 7 to 12 years old, were given the Children's Depression Inventory, the State-Trait Anxiety Inventory for Children, and the Piers-Harris Self-Concept Scale. First-born children scored significantly lower on depression than second-, third-, fourth-born, and youngest children. First borns showed significantly less trait anxiety than third-born children. First-born children also showed significantly higher levels of self-esteem than second-born and youngest children. Girls in this study showed significantly more trait anxiety than boys. 相似文献

Location-based geosocial networking smartphone applications (GSN apps) have become a popular way to meet romantic and casual sex partners. Although first used primarily by men who have sex with men (MSM), GSN apps are now commonly used in the population at large, particularly among emerging adults. Although, these apps may potentially contribute to increases in STI/HIV incidence, previous research linking GSN app use to sexual risk behavior has been mixed, with some suggesting app users report greater sexual risk behavior and others suggesting less. The present paper details findings of two studies with independent samples of emerging adults. The first, a pilot study, examined GSN app use among young MSM (n = 64) to identify possible within-group factors relating dating app use to sexual risk behavior. Results indicated that the time app users spent talking to each other through the app before meeting in person (time before meeting) was related to engagement in sexual risk behavior. Those who talked less before meeting in person engaged in more sexual risk behaviors than those who spent more time talking before meeting in person. The second study sought to expand upon this finding in a more representative sample of GSN app users (n = 129) and compared sexual risk behavior and impulsivity to non-users (n = 88). There were no differences in sexual risk behavior between GSN app users and non-users. However, when examining app users by time before meeting, those with a shorter time before meeting were more impulsive and more likely to report sexual risk behavior. These findings highlight the importance of understanding GSN app use in the spread of STIs/HIV among emerging adults. 相似文献

The possibility of anisotropies in visual space in and near the final location of a moving target was examined. Experiments 1 and 2 presented a moving target, and after the target vanished, participants indicated the final location of the leading or trailing edge of the target. Memory for both edges was displaced forward from the actual final locations, and the magnitude of displacement was smaller for the leading edge. Experiments 3 and 4 also presented stationary objects in front of and behind the final location of the target, and participants indicated the location of the nearest or farthest edge of one of the stationary objects. Memory for the near or far edge of an object in front of the target was displaced backward, and memory for the near or far edge of an object behind the target was displaced forward; the magnitude of displacement was larger for objects in front of the target and when the edge was farther away. The findings (a) suggest representational momentum is associated with an anisotropy of visual space that extends across and outward from the moving target and (b) are consistent with previous findings regarding estimation of time-to-contact, anorthoscopic perception, and memory psychophysics. 相似文献

The neural plasticity necessary for acquisition and retention of eyeblink conditioning has been localized to the cerebellum. However, the sources of sensory input to the cerebellum that are necessary for establishing learning-related plasticity have not been identified completely. The inferior colliculus may be a source of sensory input to the cerebellum through its projection to the medial auditory thalamus. The medial auditory thalamus is necessary for eyeblink conditioning in rats and projects to the lateral pontine nuclei, which then project to the cerebellar nuclei and cortex. The current experiment examined the role of the inferior colliculus in auditory eyeblink conditioning. Rats were given bilateral or unilateral (contralateral to the conditioned eye) lesions of the inferior colliculus prior to 10 d of delay eyeblink conditioning with a tone CS. Rats with bilateral or unilateral lesions showed equivalently impaired acquisition. The extent of damage to the contralateral inferior colliculus correlated with several measures of conditioning. The findings indicate that the contralateral inferior colliculus provides auditory input to the cerebellum that is necessary for eyeblink conditioning. 相似文献

Self- and partner-ratings on trait affect and the Big Five were obtained from 74 married and 136 dating couples. The relationship satisfaction of each person (the "target") was correlated with four sets of ratings: (a) target's self-rated personality, (b) target's partner-rated personality, (c) partner's self-rated personality, and (d) partner's target-rated personality. Self- and partner-ratings of the target's personality yielded very similar results. Negative and positive affectivity were consistent predictors of satisfaction in both samples. Conscientiousness and agreeableness were reliably related to satisfaction in the dating couples, whereas extraversion consistently correlated with satisfaction in the married couples. These traits jointly predicted as much as 34% (self-ratings) and 26% (partner-ratings) of the variance in satisfaction. In contrast, the partner's personality played a lesser role in satisfaction. 相似文献

The authors conducted 2 studies regarding behavior perceptions of "self" and "typical other" in hypothetical replications of S. Milgram's (1963) obedience experiment. In Study 1, participants' knowledge about Milgram's actual results was manipulated. Regardless of knowledge, results demonstrated several specific social and perceptual biases (e.g., the self-other bias; J. D. Brown, 1986), in addition to several general, fundamental lessons of social psychology (e.g., the perseverance of lay dispositionism). Study 2 was designed to explore the possibility that participants' own academic interests and worldview could influence the biases explicated in Study 1. The authors assessed perceptions of both criminal-justice majors and non-criminal-justice majors regarding their perceptions of behaviors of self and typical other. The criminal-justice students' self-other obedience estimates were significantly higher than those of the non-criminal-justice students. Further, the self-other discrepancy for criminal-justice students was significantly smaller than the difference reported by non-criminal-justice majors, suggesting that the criminal-justice students demonstrated the self-other bias significantly less than non-criminal-justice students in this context. The findings indicate that specific social-perceptual biases may have been moderated by career interest and worldview. 相似文献

Recall accuracy decreases over successive memory trials using similar memoranda. This effect reflects proactive interference (PI) – the tendency for previously studied information to reduce recall of new information. However, recall improves if memoranda for a subsequent trial are semantically dissimilar from the previous trials. This improvement is thought to reflect a release from PI. We tested whether PI is reduced or released from the semantic category for which it had been induced by employing paradigms which featured inducement, semantic switch, and then return-to-original category epochs. Two experiments confirmed that PI was not released after various semantic switch trials (effects from d?=??0.93 to ?1.6). Combined analyses from both studies demonstrated that the number of intervening new category trials did not reduce or release PI. In fact, in all conditions recall accuracy decreased, demonstrating that PI is maintained and can increase after the new category trials. The release-from-PI account cannot accommodate these broader dynamics of PI. This account is also incongruent with evidence and theory from cognitive psychology, linguistics, and neuroscience. We propose a reintroduction-of-PI account which explains these broader PI dynamics and is consistent with the wider psychological and neurosciences. 相似文献
