Scene perception: Detecting and judging objects undergoing relational violations

Five classes of relations between an object and its setting can characterize the organization of objects into real-world scenes. The relations are (1) Interposition (objects interrupt their background), (2) Support (objects tend to rest on surfaces), (3) Probability (objects tend to be found in some scenes but not others), (4) Position (given an object is probable in a scene, it often is found in some positions and not others), and (5) familiar Size (objects have a limited set of size relations with other objects). In two experiments subjects viewed brief (150 msec) presentations of slides of scenes in which an object in a cued location in the scene was either in a normal relation to its background or violated from one to three of the relations. Such objects appear to (1) have the background pass through them, (2) float in air, (3) be unlikely in that particular scene, (4) be in an inappropriate position, and (5) be too large or too small relative to the other objects in the scene. In Experiment I, subjects attempted to determine whether the cued object corresponded to a target object which had been specified in advance by name. With the exception of the Interposition violation, violation costs were incurred in that the detection of objects undergoing violations was less accurate and slower than when those same objects were in normal relations to their setting. However, the detection of objects in normal relations to their setting (innocent bystanders) was unaffected by the presence of another object undergoing a violation in that same setting. This indicates that the violation costs were incurred not because of an unsuccessful elicitation of a frame or schema for the scene but because properly formed frames interfered with (or did not facilitate) the perceptibility of objects undergoing violations. As the number of violations increased, target detectability generally decreased. Thus, the relations were accessed from the results of a single fixation and were available sufficiently early during the time course of scene perception to affect the perception of the objects in the scene. Contrary to expectations from a bottom-up account of scene perception, violations of the pervasive physical relations of Support and Interposition were not more disruptive on object detection than the semantic violations of Probability, Position and Size. These are termed semantic because they require access to the referential meaning of the object. In Experiment II, subjects attempted to detect the presence of the violations themselves. Violations of the semantic relations were detected more accurately than violations of Interposition and at least as accurately as violations of Support. As the number of violations increased, the detectability of the incongruities between an object and its setting increased. These results provide converging evidence that semantic relations can be accessed from the results of a single fixation. In both experiments information about Position was accessed at least as quickly as information on Probability. Thus in Experiment I, the interference that resulted from placing a fire hydrant in a kitchen was not greater than the interference from placing it on top of a mail ? in a street scene. Similarly, violations of Probability in Experiment II were not more detectable than violations of Position. Thus, the semantic relations which were accessed included information about the detailed interactions among the objects—information which is more specific than what can be inferred from the general setting. Access to the semantic relations among the entities in a scene is not deferred until the completion of spatial and depth processing and object identification. Instead, an object's semantic relations are accessed simultaneously with its physical relations as well as with its own identification.     

Social comparisons and pay evaluations: Preferences for same-sex and same-job wage comparisons

This research examined women's and men's social comparison preferences when evaluating the fairness of pay. Subjects were assigned randomly to work on a job described as masculine, feminine, or sex neutral and were told that they would be paid for their work. After working on the job and privately receiving identical payment, subjects rank ordered their preference for seeing the average male, average female, and average combined-sex wage paid in each of the three jobs. Despite the availability of the combined-sex wage, subjects preferred to maximize similarity in their wage comparisons, with the majority choosing to see the pay of a same-sex and same-job group first. Regardless of the sex linkage of their job assignment, subjects selected a same-job comparison first. Sex linkage of job did affect same-sex preferences; whereas subjects in sex-appropriate and sex-neutral jobs showed a significant preference for seeing the pay of same-sex others first, subjects in sex-inappropriate jobs did not. Results also indicated that both men and women assigned to the feminine job expected somewhat less pay and thought their obtained pay was more fair than did those assigned to the masculine job. Furthermore, women thought they deserved less pay for their work than did men, regardless of their job assignment. Implications of these results for gender differences in outcome evaluations are discussed.     

On processing chinese ideographs and english words: some implications from Stroop-Test results.

When Chinese subjects tried to name the color of characters which represented conflicting color words, they showed markedly greater interference than did English speaking readers performing an English version of the same task. This effect cannot be attributed to bilingualism among the Chinese subjects since bilinguals in other languages show smaller Stroop-interference than monolingual controls. Instead, there may be some fundamental differences in the perceptual demands of reading Chinese and English which can have widespread implications for human information processing.     

Children's binary prediction of partially learnable sequences followed by an all-correct procedure

Six groups of 20 subjects each were run individually in a binary prediction situation with each alternative occurring equally often. Two age groups were employed; subjects were either in second or sixth grades. For one-third of the subjects at each age level, the events occurred in runs of either two or six; another third observed events which occurred in runs of either five or six; the other subjects received a random sequence of events. All subjects then received an additional 50 trials in which every prediction was correct. The results indicated some sensitivity to run length characteristics. Fewer errors of all types were made in the prediction of 5–6 sequences. The verbal reports and all-correct trial protocols revealed that at least the sixth graders employed some simple run length structure rules, although many instances of runs other than those presented in training occurred, showing much processing error. The results were discussed in terms of a general limited-capacity model of information-processing.     

Effect of preacquisition UCS exposure on classical conditioning of the rabbit's nictitating membrane response

Conditioning of the rabbit nictitating membrane response was found to be inversely related to the number (0, 50, 200, 350) and intensity, (0, 1, 3, 5 mA) of preacquisition UCS exposures and directly related to the interval between preexposure and acquisition (0 or 24 hr). The results were discussed in terms of sensory adaptation, habituation, blocking, and emotional reactivity.     

Processing the information contained in another's behavior

This study investigates attributions based on behavior congruent with situational demands (in-role) and those based on behavior incongruent with situational demands (out-of-role). By analyzing these processes in terms of a Bayesian inference model, it was possible to determine (a) the diagnostic values observers intially assign to behaviors, (b) the actual informational impact of these behaviors, and (c) the degree of optimality in processing information contained therein. The main results can be summarized as follows: (1) The diagnostic value and actual informational impact of out-of-role behaviors were much higher than those of inrole behaviors. (2) Information about out-of-role behaviors was less optimally processed than information about in-role behaviors. (3) Observers assigned smaller diagnostic values to behaviors which were described in great detail than to behaviors which were described in summary statements. (4) Observers' attitudes influenced their initial beliefs about the actors but not the processing of new information about the actor. (5) The Bayesian inference model predicted observers' inferences reasonably well.     

Pigeons' performance under differential reinforcement of low rate schedules depends upon the operant

Pigeons were reinforced with grain for pecking a key or depressing a foot treadle according to differential reinforcement of low rate (DRL) schedules. Birds which depressed a treadle performed efficiently on DRL schedules as high as DRL 35-sec; while birds reinforced for keypecking showed low efficiency under DRL 14-sec. While treadle pressing and keypecking differ along a number of dimensions (including force requirement of the operant and differences in temporal distributions of responses), the present results are consistent with an interpretation based on differences in the degree to which these two responses are elicited by periodic presentations of food.     

Training cooperation in the Prisoner's Dilemma

Female Ss' choices in two types of mixed-motive game situations were used to select Ss who had predominantly Own Gain and Ss who had predominantly Relative Gain goals. On the basis of simple reward notions, it was predicted that the former but not the latter would change from competitive to cooperative responding in decomposed Prisoner's Dilemma game situations when interacting with a conditionally cooperative other. Corresponding yoked controls were not expected to become cooperative. The availability of social comparison with an outcome which was smaller than the mutually cooperative outcome but larger than the mutually competitive out-come was expected to lead Own Gain Ss to more rapid learning of cooperation but not to affect the responses of corresponding yoked controls or of Relative Gain Ss. A 2 × 2 × 2 × 5 factorial design was used in which the factors were goal orientation (Own Gain vs Relative Gain), strategy of the other (conditionally cooperative vs yoked control), the availability vs unavailability of the social comparison, and trials. The results strongly supported each of the expectations. The results were discussed in terms of how the operation of the reward mechanism would be affected by the operation of some other social psychological processes.     

The sources of developmental differences in children's incidental processing during discrimination trials

Crane and Ross reported that second graders learned more than sixth graders about attributes made relevant after solution of a discrimination task. Here two experiments are reported that enlighten the sources of this developmental difference. Both make use of an experimental technique whereby children verbalize their hypotheses during solution of a discrimination problem. The results indicate that ten-year-olds do not learn about incidental attributes that they tested while irrelevant in the pre-solution period, but that five-year-olds and seven-year-olds do. Children of all three ages process incidental information about attributes that they did not sample pre-solution. With some qualification, the incidentally processed information is retained throughout a five-minute delay interval. The results bear on developmental trends in the distribution of attention and on theoretical accounts of incidental learning in discrimination tasks.     

Children's ability to integrate class information

Coordination and integration of class information was examined using a multidimensional similarity judgment task in which four- and nine-year old children rated the similarity of pairs of stimuli sharing either one or two atribute values. Half the children at each age were assigned to an attention condition requiring they label relevant stimulus atributes before making their similarity ratings. The other children were in the nonattention condition, and rated similarity without labelling the attributes. The results indicated that four-year-olds in the attention condition and nine-year-olds in both conditions integrated class information in making their similarity judgments. Performance of the four-year-olds in the non-attention condition tended to improve across trials; they appeared to integrate class information on later trials.     

A note on remembering to execute planned actions

The purpose of this article is to call attention to the necessary role of remembering in the execution of planned actions, such as following instructions, delivering messages, and keeping appointments. Remembering in this context is considered within a theoretical framework of activities, actions, and operations advanced by Soviet developmental psychologists. The importance of remembering planned actions in applied settings, strategies employed by children and adults in remembering planned actions, relationships between motivation and remembering, and developmental relationships are discussed. In addition, several characteristics of the Soviet developmental approach are briefly noted.     

Humphreys's attenuated test of Spearman's hypothesis

Humphreys's test of Spearman's hypothesis (viz., that the size of the standardized black-white differences on various psychometric tests is positively related to the tests' loadings on g, the general intelligence factor) is methodologically weak. It is based on comparison of a fairly representative sample of the black population of U.S. school children with a highly selected sample of the white school population, representing the lowest 15 to 20% of whites in socio-economic status (SES). A fair test of the hypothesis requires that the black and white samples should not be selected on any g-correlated variable, such as SES. Selection attenuates and distorts the relationship between tests' g loadings and the magnitude of the standardized mean black-white differences on the tests. Other unorthodox conditions in Humphreys's study, such as performing factor analysis on the test-score means of various arbitrary demographic groups instead of on individual test scores inflates tests' g loadings and biases the test of Spearman's hypothesis by restriction of reliable variance in g loadings. Humphreys's study cannot be considered a proper replication of Jensen's examination of Spearman's hypothesis in 11 different studies comprising 74 different tests, which consistently bears out Spearman's hypothesis.     

Measuring women's interests using Holland's vocational classification

A Hebrew interest inventory for females in Israel, based on Holland's 1966 1973 vocational classification, was examined on 322 female pupils and 167 working females. Results showed that: (a) with the exception of the Conventional and Enterprising fields, subjects occupied in a field had their highest interest score in that field; (b) for all six interest fields, the highest interest score was the score of those who were engaged in that field; (c) in a smallest space analysis, the activities, competencies, and occupation sections of the interest inventory formed the Investigative, Realistic, Artistic, Social, Enterprising, and Conventional circular arrangement; (d) a correlation of .38 between interest score and job satisfaction was found.     

Critical evaluation of Guilford's structure-of-intellect theory

The structure-of-intellect (SI) theory is evaluated within a framework of considerations of capitalization on chance. This empirical problem is placed in a larger perspective of concern for the general conceptual value of the theory in the study of human intelligence. The factor analytic support for the theory is found to be lacking in several notable respects. At best the research intended to support the model must be considered exploratory. But the model has provided a useful scheme for test construction and for indicating interesting hypotheses about qualities of intellect. Even in this context, however, there are several problems with the theory. The theory provides only a static taxonomy and thus affords very limited possibilities for understanding developmental issues.     

Repetition of cues in children's oddity learning and transfer

The hypothesis that repetition of specific cues interferes with oddity learning was directly tested by comparing two groups of preschool (3 to 5 years of age) children, one with repeated cues and the other with new cues on every trial. Repetition of cues retarded oddity learning confirming previous speculation based on error analyses. Performance on postsolution transfer trials with repeated cues was not affected by conditions of acquisition. Significant age effects were found in oddity acquisition, while there was only weak evidence for agerelated performance differences on transfer trials. Transfer performance on trials with repetition of cues was not related to whether or not the children were informed of such repetition. The results were related to theories of oddity acquisition and transfer.     

Category similarity effects in children's semantic memory retrieval

Fourth-, sixth-, and eighth-grade students were required to indicate whether or not a stimulus word belonged in either of two semantic categories that were held in memory. Each category pair was either semantically similar or semantically dissimilar. The results indicated that even for the youngest children, similar categories required less search time than dissimilar categories. It was suggested that while dissimilar categories had to be accessed successively prior to search, subjects were able to consolidate similar categories into a superordinate group which eliminated the time to shift from one category to another during search. The results were contrasted with clustering studies which have demonstrated a minimal amount of memory facilitation in children for conceptually related items over unrelated items.     

Defining the locus of developmental differences in children's causal reasoning

Five experiments were performed in the area of children's causal reasoning to validate a previously reported developmental difference, to examine the role of a possible mediating mechanism, and to test a number of competing theoretical interpretations. As previously, the regularity of a cause-effect pairing influenced the causal attributions of 8- and 9-year-olds but not of 5- and 6-year olds; the results were found not to be artifacts of either a response induced commitment to choosing a particular object or the brevity of the exposure period. The developmental difference also was not explained by discrepant encoding of the term “cause,” by memorial deficiencies, or by differences in criteria for drawing causal inferences. Instead, it appeared that greater perceptual distractibility prevented the younger children from searching for and finding the temporally invariant relationship hypothesized to be crucial to inferring causality in the experimental situation.     

Categorical and spatial modes of representation in young children's recall

Preschool children aged 4 and 6 were asked to recall a set of line drawings under two conditions: pictures blocked in category groups, and pictures blocked in noncategory groups. For 4-year-olds, the blocking condition made no difference in the structure of their recall; but for the 6-year-olds, the category blocking served as a support for category clustering of their recall lists. No purely spatial clustering appeared at either age. It was concluded that 6-year-olds' use of classes is closely linked to concrete spatial arrangement of objects.     

The layman's use of trait and behavioral information to predict behavior

This study investigated conditions that determine subjects' preferences for information about another person's traits versus his specific past behavior in order to predict his future behavior. The similarity-dissimilarity between the situation for which past behavior was available and the one to which predictions had to be made strongly influenced the choice of specific behavioral information versus more general trait information. As expected, behavioral information was preferred most when the situation to which behavior had to be predicted was highly similar to the one for which the past behavioral data were available. On the other hand, more general trait information was preferred in predicting to situations that were not directly similar to those for which past behavioral information was available. The effect of the temporal span covered by available information was also explored.
