Spatial coding and oblique discrimination by children

Children from five to eight years of age learned to discriminate between mirrorimage oblique lines more readily when cards bearing the obliques were presented vertically than when they were presented horizontally. The difference in performance between the vertical and horizontal planes could not be accounted for by differences in either the external visual context or the availability of asymmetrical body information (e.g., left vs right hand). The superiority of the vertical plane was attributed to the congruence of objective, bodily, and retinal vertical axes for the vertical, but not the horizontal plane, It was concluded, on this basis, that at least part of children's difficulty discriminating between mirror-image obliques is due to their difficulty establishing the internalized vertical axis necessary for the left-right spatial coding of the obliques.     

Frustration,attribution of blame,and aggression

In contrast to most recent studies of human aggression, multiple measures of naturally occurring aggressive behavior were examined in a realistic and involving setting. Consistent with attributional formulations, it was found that aggression increased in accord with attributions of blame, and that more blame was attributed to another in response to inadequately justified thwartings than to adequately justified thwartings. As anticipated, anger, other-directed attributions of blame, and other-directed aggression were greatest in response to unjustified (illegitimate) thwartings. Justified (legitimate) thwartings produced intermediate anger and intermediate levels of blame and aggression internally and externally. Self-caused (internal) thwartings, ostensibly caused neither by the other's disposition nor by situational factors, produced the least anger and other-directed aggression but the most self-blame/self-aggression. In addition, unexpected thwartings produced independently more anger than did expected thwartings, and high-drive thwartings produced independently less other-directed aggression than did low-drive thwartings. The results are discussed with reference to both the need and the potential for studies of human aggression which employ more ecologically valid settings and measures of aggressive behavior.     

Measuring the visual angle of the mind's eye

People in these experiments claimed to be able to imagine moving only a given distance toward some imaged object before it seemed to “overflow,” not remaining all visible at once in their mental images. In addition, the larger the imaged object, the further away it seemed at the point of overflow. Although the angle subtended by the imaged objects at the point of overflow did not vary systematically with the size of the object, it did vary with different stimuli and instructions. These disparities in the size of the angle estimated seemed partly due to differences in criterion of “overflow”: Images seem to fade off gradually toward the periphery and not to occur in a spatial medium with sharply defined edges. When subjects were given a relatively strict definition of “overflow,” similar estimates of the “visual angle of the mind's eye” were obtained with three distinct methods: (1) Asking subjects to estimate the apparent distance at which an imaged horizontal ruler began to overflow; (2) Measuring how much time subjects required to scan across each degree of an imaged line, and then inferring the maximal angle from the time required to scan an image of a longest nonoverflowing line; and, (3) Simply asking subjects to hold up their hands to indicate the subjective size of an image of the longest possible nonoverflowing line. Finally, the maximal subjective size of images seemed related to the scope of “focal” vision, and images tended to be constructed spontaneously at about the maximal size.     

Transformations,basic operations and language acquisition

Errors in child speech show that some children initially formulate tense-hopping and subject-auxiliary inversion as copying without deletion. Other errors suggest that some children may formulate other movement rules as deletion without copying. A claim about the nature of the language acquisition device is made on the basis of our analysis of these errors: the language acquisition device formulates hypotheses about transformations in terms of basic operations. The basic-operations hypothesis predicts that for any transformation which is composed of more than one basic operation, there exists a class of errors in child speech correctly analyzed as failure to apply one (or more) of the operations specified in the adult formulation of the rule.     

Logical competence and transitive inference in young children

Five-year-old children were trained on the length relationships between the adjacent members of a five-term series of sticks. They were then tested on their abilities (1) to judge the length relationships between nonadjacent pairs of the series, and (2) to incorporate an unseen novel stick into the series through inference. Children who were trained with sticks of markedly different lengths succeeded on the first test but not the second; they apparently relied on memory for the absolute lengths of the sticks. Children in the other groups succeeded on both tests. The critical factor in inducing the use of seriation and transitivity seemed to be the elimination of alternative solutions.     

Ending social encouters

Certain classes of verbal behavior—content summary statements (S_c); affective summary statements (S_a); continuity (C), justification (J), and well-wishing (W) statements; and statements of positive affect (P)—were hypothesized to be constituents of interpersonal endings. These statements are shown to increase during the terminal phase of a social encounter as a function of whether the conversation is between friends or strangers and whether it is structured or unstructured. A hypothesis concerning the sequence in which these five classes of statements will occur during the ending of an interaction, namely, [S_c] → [J] → [_Sa^P] → [C] → [W], is tested and confirmed.     

Commitment,ego-involvement,and resistance to attack

Subjects with initially extreme or moderate positions (based on a median split) recorded a consonant speech under public, private, or no commitment and later received a strong, mild, or no attack on their position. Extremes were more ego-involved in terms of wider latitudes of rejection, narrower latitudes of non-commitment, and greater resistance to attack, relative to moderates. Commitment had no effect for extremes, suggesting a ceiling effect on changes in the latitudes and resistance to attack for initially high levels of ego-involvement. For moderates, commitment resulted in narrower latitudes of noncommitment, wider latitudes of rejection (greater rejection of discrepant positions), and greater resistance to attack, suggesting that commitment may elevate ego-involvement with the issue. Commitment and ego-involvement may increase the salience of one's attitude position in later situations, thereby increasing the probability of attitudeconsistent behavior.     

Social judgments of spurious and causal relations between attributes and outcomes

People can learn about relations between attributes and outcomes by observing the attributes and outcomes of others, but, as this experiment indicates, such learning is not always veridical. Each subject received information about the ages, educations, and salaries of groups of employees in a fictitious corporation. Within a group, either age or education was related to salaries and the two attributes were either orthogonal or correlated. In each case, subjects judged the strength of the causal relation between each attribute and salaries. The results confirmed our hypothesis that observers are more likely to view a causally relevant attribute as irrelevant, and a causally irrelevant attribute as relevant, when relevant and irrelevant attributes are correlated. However, this tendency seemed to be mediated by subjects' bias to prefer education as an explanation of salary differences: That is, when age and education were correlated, subjects tended to view education as relevant even when it was irrelevant and age as irrelevant even when it was relevant. The results suggest that when attributes are correlated, factors extraneous to observed data may have a major influence on inferred attribute-outcome associations.     

The effect of race,sex, and career goal differences on sex role attitudes at home and at work

Male and female blacks and whites whose career goals differed as to sex role stereotypy were administered two sex role inventories. One measured attitudes toward women's expanding sex roles in the home/personal environment, while the other measured sex role attitudes in the working environment. The major finding of the present study is that black women had more traditional sex role attitudes in the home environment than white women but the same sex role attitudes about working, whereas both black and white women were more liberal in their sex role attitudes in both environments than black and white men.     

Concurrent validity of Holland's theory for non-college-degreed working women

This study, using the Vocational Preference Inventory (VPI) and the Self-Directed Search (SDS), explored the concurrent validity of Holland's theory for employed non-college-degreed women. The VPI and SDS were administered to 114 women workers in occupational environments consistent with Holland's vocational environments. The results revealed that three scales of the VPI and five scales of the SDS successfully differentiated the occupational groups consistent with Holland's theoretical notions. In general, the findings lend some support to the concurrent validity of Holland's theory for employed non-college-degreed women.
