The effects of setting similarity on children's learning of the transverse patterning problem

A group of 15 fourth-graders were given training on the transverse patterning problem, a task consisting of three different geometric forms presented in pairs. Three other groups of 15 fourth-graders each received training on problems containing the same geometric forms, along with either one (color or size) or two (color and size) additional nonspatial dimensions varying among the settings comprising the different cue-cue patterns. Contrary to a prediction derived from Croll's (1967) extension of Spiker's (1963) theory of discrimination learning, none of the Ss solved the basic transverse patterning problem, nor was there any improvement in performance on this problem after 90 trials. Consistent with predictions derived from Spiker's theory, it was found that the addition of one nonspatial dimersion resulted in solution, and that the greater the number of nonspatial dimensions present, the better the learning.     

Sex-role aspects in the development of children's vocational knowledge

Recent research suggests important age and sex differences in the sex-typing of children's vocational interests. The present study adds to this area by examining several dimensions of job choices in children of four age groups (early and late preschool, second and fourth grade). The 120 children interviewed were asked three fixed-choice questions regarding nine jobs, along with open-ended job choice items. Analysis of age effects on several predetermined dimensions showed that older children were more selective in personal job choice, especially in regard to jobs attributed to the opposite sex. Avoidance of choices associated with the other sex was stronger in boys, but other sex differences were dependent on mode of inquiry rather than on sex. Girls were less limited than boys in job interests when asked about specific jobs but expressed more restricted choices on open-ended items. Implications of these findings both for further research and educational practices are considered.     

Decision processes in children's recognition memory

Kindergarteners and third graders were given a continuous recognition memory task involving two-digit numbers. In addition, a rating scale consisting of photographs of various facial expressions was used to obtain confidence judgments from the Ss. Conventional analyses as well as signal detection analyses of the data revealed the following results: (a) the overall performance of the third graders was superior to that of the kindergarteners; (b) memory strength decreased as the number of intervening items increased; (c) there was no difference in the forgetting rates of the two grade levels; (d) the third graders exhibited a more liberal response bias than the kindergarteners; (e) both the hit rate (probability of correctly labeling an old stimulus as old) and the false-alarm rate (probability of incorrectly labeling a new stimulus as old) increased across blocks of items; (f) the increases in the hit rate and the false-alarm rate over blocks were due to a change in criterion from a relatively conservative level to a more lenient one; (g) the lower the S's level of confidence in judging an item as old, the lower was the probability of that item actually being old; (h) the third graders were better than the kindergarteners at gauging the accuracy of their recognition responses. It was concluded that with respect to recognition memory, chidren as young as $\text{5}\text{1}\text{2}$ years old are capable, to some extent, of monitoring their own memory states.     

Picture superiority in free recall: The effects of organization and elaboration

A conception of semantic memory structure is presented in which elaboration is considered to vary both between and within items. Pictures and their verbal labels are suggested to activate common abstract memory representations, but these activations will differ in their degree of within-item elaboration. However, pictures and words should show comparable between-item elaboration properties, such as might be revealed by the category-recall relationship and clustering in free recall. Children were presented pictures and words in either a category-recall situation, where between-item elaboration was emphasized, or in a control situation where between-item elaboration was minimized. No differences between pictures and words in either recall or clustering were found in the category-recall task. However, when the same items were presented in the control situation the typical picture superiority effect in free recall was found. The results are interpreted as consistent with a two-factor theory of semantic elaboration, and indicate that these basic properties of memory encoding hold even for young children.     

The effect of cuing after backward conditioning trials

Rats were given backward pairings of a tone (CS) and shock (US) and were then tested for response to the CS in a lick suppression test. Animals given a cuing or reminder treatment prior to the test exhibited enhanced suppression in the presence of the tone relative to a variety of control conditions. The cue-induced suppression enhancement did not appear to result from sensitization or short-term motivational changes nor did it seem to depend on second-order conditioning of the test context. The effect appeared more robust as the number of backward conditioning trials preceding the cue increased. The results were discussed in terms of current explanations of backward conditioning effects.     

Mediators between frustration and aggression in a field experiment

To assess some of the mediators between a frustrating incident and subsequent aggressive behavior in a field situation, 320 male and female subjects were assigned to one of 32 experimental conditions in a 2 × 2 × 2 × 2 × 2 factorial design. Either a male or female experimenter, saying “Excuse me” or not, dressed in high or low status clothing, cut in line in front of the subject, who was standing near the front or back of the line. Verbal and nonverbal aggressiveness were coded and summed to measure total aggression. Subjects near the front of the line or interacting with a low status experimenter were more aggressive than those at the back of the line or seeing a high status experimenter. Less aggression was directed against the female experimenter or one who said “Excuse me,” and there was a strong tendency for subjects to be more aggressive to a same-sex experimenter. It was suggested that further research on instigators to aggression be carried out in such field situations.     

Let's pretend: The role of motoric imagery in memory for sentences and words

A number of theories suggest that for young children, concepts should have an important motoric (or sensory-motor) component. A levels-of-processing theory is proposed which predicts that processing on motoric imagery should facilitate memory for both isolated words and for sentences. Experiment 1 examined the effects of motoric enactment (viz., pretend play) of sentences on memory for the sentences. Motoric imagery facilitated memory for both children (5 to 7 years of age) and adults, though, contrary to expectations, the effects were weaker for the children than for the adults. Further, it was found that motoric imagery affected the initial acquisition, but was not important as a retreival cue. Experiment 2 examined the effects of motoric imagery on free recall of lists of unrelated words. Under these conditions, motoric imagery facilitated memory for both children (7 to 9 years of age) and adults equally; in contrast, visual imagery instructions had no effect on memory. These results indicate that motoric imagery may facilitate memory under conditions in which visual imagery has no effect. Theoretical implications are explored for previous experiments on pretend play which suggest that training for pretent enactment can facilitate cognitive development.     

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.     

The effects of perceptual pretraining on concept identification and preference

The effects of perceptual pretraining on preferences and concept identification performance in five- and eight-year-old Ss were investigated. The results indicated that perceptual pretraining facilitated performance on a concept identification task with a non-preferred relevant cue for the five-year-olds, but not for the eight-year-olds. However, perceptual pretraining did not affect preference in either age group and Ss were as consistent in their preference responding before and after perceptual pretraining as was a control group that had not received perceptual pretraining. Preferences were highly consistent in both age groups over a one week period. Perceptual pretraining was interpreted to increase the usability of the less preferred dimensions for the younger Ss, and to leave the affective preference response unaltered in both groups.     

A Plumber's friend in need is a Plumber's friend indeed

In response to the critique of Gaes, Quigley-Fernandez, and Tedeschi (Journal of Research in Personality, 1978, 12, 189–192) it was acknowledged that the cell Ns were incorrect as originally reported, and the weakness of a postexperimental division of subjects was reaffirmed. Emphasis was placed on the comparability of a simple rating scale and an elaborate bogus pipeline in measuring attraction. The need for determining the way in which the bogus pipeline functions prior to its uncritical adoption in any given experimental situation was stressed as a point of agreement.     

Playing hard-to-get: A two-determinant model

Walster, Walster, Piliavin, and Schmidt (Journal of Personality and Social Psychology, 1973, 26, 113–121) found that a hard-to-get woman was liked only if she was hard-to-get for other men but easy-to-get for the subject. They suggested that the subjects liked this type of woman because of the socially desirable personality characteristics they attributed to her. A second determinant of liking is proposed in the present study. It concerns the effect of a person's evaluation of a subject on the subject's self-esteem. It was predicted that there would be a positive relationship between changes in the subject's self-esteem and liking for the evaluator. The results demonstrated that this determinant, as well as the one that Walster et al. suggested, is important in understanding the type of opposite-sex person that men and women find most attractive. These results, and the differences between the Walster et al. and the present studies, were discussed in terms of the relative impact of the two determinants in laboratory and real-life situations.     

Attribute identification in children as a function of stimulus dimensionality

Thirty-two four-year-old and 32 six-year-old children were presented a conjunctive concept that involved either two values from within a single dimension (unidimensional condition) or two values from different dimensions (bidimensional condition). As predicted, the results showed that the uni- vs bidimensional factor had no effect upon the performance of the younger children, while the older children solved more rapidly in the unidimensional than in the bidimensional condition. The results were interpreted to suggest that the younger children's responding is not under dimensional control and that a major source of difficulty for older children solving the conjunctive concept is the necessity of responding to two dimensions, not to two values.     

A probe trial procedure for the study of children's discrimination learning and transfer

A discrimination reversal problem was presented to 192 children varying in age from 3 to 5 years. At the end of both the initial learning and transfer trials, probe trials were introduced to ascertain the response rule describing children's choices. Results were analyzed in terms of a binary division of the children according to their responses to the probe stimuli; children who responded errorlessly (concept responders) were contrasted with children who made errors on the probes (instance responders). Using this criterion, it was found that many children transferred in a way different from the way they learned the initial problem. There was no difference in the proportion of younger and older children responding conceptually to the original problem, but older children were more likely to transfer conceptually when standard geometric blocks were used as stimuli. Future studies must consider the possiblity that learning and transfer may be accomplished by different processes whose application differs with age, the nature of the stimuli, and the stage of training.     

Vocational development in early childhood: An examination of young children's expressions of vocational aspirations

Vocational aspirations were investigated in a sample of 282 children between the ages of 3 and 6. Age comparisons suggested that one aspect of vocational development in early childhood involves mastery of the task of projecting oneself into the future and conceiving of oneself as one day achieving adult status. Race comparisons indicated that urban blacks were less mature than urban whites in terms of mastery of the vocational projective task seen as characteristic of this developmental period. No significant sex differences were found in rate of development. However, there were indications that the pattern of vocational projection differs for males and females and that females undergo occupational foreclosure earlier than their male peers. Implications for vocational development theories are discussed.     

A theoretical analysis of the PAN ambiguous-cue problem

The PAN ambiguous-cue problem consists of three stimuli: P, the positive (consistently rewarded) cue; N, the negative (consistently nonrewarded) cue; and A, the ambiguous cue which is negative (nonrewarded) when paired with P, but positive (rewarded) when paired with N. This paper demonstrates how the finding of superior performance on the NA trials as compared to the PA trials (with stereometric objects) can be rigorously derived from a recent extension of Hull-Spence discrimination learning theory, the Stimulus Interaction Hypothesis. It is also shown how this theory can account for the converse outcome of better performance on PA than on NA trials when planometric plaques are used as stimuli. Finally, alternative explanations of the findings are described and evaluated.     

Moral outrage and pragmatism: Explanations for collective action

Two explanations for collective behavior were contrasted. The first, exemplified by relative deprivation theory, stresses the importance of feelings of moral outrage and perceived economic injustice. The second focuses on more pragmatic considerations, such as the availability of resources for mobilization. The present study examines these explanations for collective behavior in a laboratory setting. Subjects were members of a disadvantaged group. In a 3 × 2 factorial design two independent variables were manipulated. The magnitude of pay inequality between the disadvantaged group and a more advantaged group was manipulated to be large, moderate, or small. Mobilization resources available to the disadvantaged group were manipulated to be either present or absent. In accord with predictions based on relative deprivation theory, as the magnitude of the inequality increased, stronger feelings of deprivation were expressed. However, contrary to relative deprivation theory, larger magnitudes of inequality and stronger feelings of deprivation were not associated with greater willingness to engage in legitimate or illegitimate forms of collective behavior. Instead, as predicted by some critics of relative deprivation theory, willinginess to engage in illegitimate forms of collective behavior was affected only by a gragmatic consideration: the presence or absence of mobilization resources.     

The alleviation of short-term retention decrements with reactivation

Retention of spatial information by rats was shown to decrease significantly over a 90-sec retention interval. However, this decrement was alleviated significantly when a reactivation or cueing treatment was presented during the 90-sec interval. Further, the rate of forgetting following reactivation was shown to be similar to that which occurs following original information input. The implications of these findings for information loss models of forgetting were discussed.     

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.     

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.
