When an observer views a moving scene binocularly, both motion parallax and binocular disparity provide depth information. In Experiments lA-1C, we measured sensitivity to surface curvature when these depth cues were available either individually or simultaneously. When the depth cues yielded comparable sensitivity to surface curvature, we found that curvature detection was easier with the cues present simultaneously, rather than individually. For 2 of the 6 subjects, this effect was stronger when the component of frontal translation of the surface was vertical, rather than horizontal. No such anisotropy was found for the 4 other subjects. If a moving object is observed binocularly, the patterns of optic flow are different on the left and right retinae. We have suggested elsewhere (Cornilleau-Pérès & Droulez, in press) that this motion disparity might be used as avisual cue for the perception of a 3-D structure. Our model consisted in deriving binocular disparity from the left and right distributions of vertical velocities, rather than from luminous intensities, as has been done in classical studies on stereoscopic vision. The model led to some predictions concerning the detection of surface curvature from motion disparity in the presence or absence of intensity-based disparity (classically termedbinocular disparity). In a second set of experiments, we attempted to test these predictions, and we failed to validate our theoretical scheme from a physiological point of view. 相似文献

We analyzed the role of the range of variation in training exemplars as a contextual variable influencing the effects of in vivo versus simulation training in producing generalized responding. Four mentally retarded adults received single case instruction, followed by general case instruction, on washing machine and dryer use; one task was taught using actual appliances (in vivo) and the other using simulation. In vivo and simulation training were counterbalanced across the two tasks for the 2 subject pairs, using a within-subjects Latin square design. With both paradigms, more errors were made after single case than after general case instruction during probe sessions with untrained washing machines and dryers. These results suggest that generalization errors were affected by the range of training exemplars and not by the use of simulated versus natural training stimuli. Although both general case simulation and general case in vivo training facilitated generalized performance of laundry skills, an analysis of training time and costs indicated that the former approach was more efficient. The study illustrates a methodology for studying complex interactions and guiding decisions on the optimal use of instructional alternatives. 相似文献

Many behaviors are performed less frequently than intended because they require knowledge and skill to overcome behavioral barriers. This experiment tested effects of two factors, direct experience and message frame, that were hypothesized to affect men's intention to perform the testicle self-exam for cancer (TSE) and their actual exam performance, in part by affecting their knowledge and beliefs about overcoming TSE performance barriers. Men's experience performing the TSE on a life-like model and the frame (negative, positive, or neutral) of the recommendation promoting the exam were manipulated factorially. Consistent with prediction, men who practiced (vs. did not practice) the self-exam: (a) endorsed stronger beliefs about behavior-specific knowledge (e.g., ability to imagine a lump), (b) held more positive intention, and (c) translated that intention more consistently into self-reported action, in part because their behavior-specific knowledge increased their tendency to act on their intention. Consistent with action phase theory (Gollwitzer, 1990), intention related more strongly to behavior-specific beliefs than to general, long-term beliefs, and more strongly than attitude related to behavior-specific beliefs. These findings have practical and theoretical implications for promoting healthful and other intended behaviors. 相似文献

Beauty Is Only "Name" Deep: The Effect of First-Name On Ratings of Physical Attraction 总被引:1,自引:0,他引:1

College students ( n = 197) voted to select a beauty queen from among six photographs equivalent in physical attractiveness, as determined by rankings of 35 students from a separate university. Half the photographs bore a desirable first-name and half were assigned an undesirable first-name. As predicted, firstname had a significant effect on physical attraction: Girls with desirable firstnames received 158 votes to 39 for those with undesirable names. These data were discussed in terms of an additive, rather than an interactive, effect, due to the nature of the task. The strength of these findings was related to the study's ecological validity. 相似文献

This paper reflects the working through of a group's fantasy that the deceased group leader wished the group to continue. As in any defense, the fantasy protected members from the pain of the finality of the leader's death. This article reveals the subjective experience concerning the effect of the leader's death on the group and members' intrapsychic struggle to separate and individuate from the deceased leader, while attending to and striving toward the group's continuation. The group's painful and growing individuation enabled the group to follow its own tasks without the spector of the deceased leader. 相似文献

Second-order conditioning of the rabbit’s nictitating membrane response (NMR) was investigated when second-order trials (CS1-CS2) were intermixed with first-order trials (CS2-US) from the outset of training. Experiment 1 showed that CR acquisition to CS1 was inversely related to the CS1-CS2 interval but nevertheless extended to an interval of 8,400 ms. Experiment 2 revealed that CR acquisition of CS1 was an inverted-U function of the number of CS1-CS2 trials relative to a fixed number of CS2-US trials. Experiment 3 directly contrasted second-order conditioning with a reinforced serial compound procedure (CS1-CS2-US) and a mixed procedure in which second-order trials were intermixed with the reinforced serial compound. Second-order conditioning was about half the strength of either the reinforced serial compound or the mixed procedure, which were similar. The present results are discussed with respect to the relative strength of excitatory and inhibitory processes in second-order conditioning. 相似文献

Two studies examined the pattern of reasons given for rejecting dates and how they reflect concerns of the rejector. Study One examined retrospective accounts of rejection. Rejectors often reported withholding the reason for rejection from the rejected person. A content analysis of the reasons communicated to rejected persons was performed using Weiner's (Journal of Educational Psychology, 1979, 71, 3–25) attributional dimensions of locus, controllability, and stability. The stated reasons were found to be primarily impersonal, uncontrollable, and unstable. Study Two examined rejectors' willingness to communicate certain types of reasons. The true, privately held reasons for turning down dates were systematically varied as to locus, controllability, and stability. The types of reasons subjects offered to rejected persons were consistent with Study One. Reasons for refusal were less likely to be revealed when they related to the appearance or personality of the rejected person, particularly when the personal reasons were uncontrollable and stable. Rejectors were not as forthright when they controlled the reason for rejection as when they lacked control. The rejectors' actions were interpreted as being self-presentational, reflecting concerns about rejected persons' emotional reactions, expectancies for the future of the relationship, and blame for rejection. 相似文献
