Developmental changes in children's use of semantic information in recall

Third and seventh graders (age 9 and 13 years) were randomly assigned to three instructional groups and engaged in a sort/recall task. The instructions emphasized either (a) recall of the items, (b) meaningful organization of the items, or (c) meaningful organization and recall of the items. Regardless of instruction, seventh graders sorted 20 unrelated items into semantically-based groupings and exhibited elevated levels of recall. Third graders instructed to group items to facilitate recall formed seemingly random groupings and recalled significantly fewer items than third graders instructed to make semantically-based groupings, even when some of these latter subjects were unaware of a subsequent recall trial. The results indicated that young children are capable of adult-like organizational strategies but are unaware of their relevance to recall performance or conditions under which organization might be an appropriate strategy.     

The naive perception of masculinity-femininity on the basis of expressive cues

Groups of naive judges rated 18 videotaped stimulus persons on masculinity, femininity, “dominance, assertiveness,” and “compassion, sensitivity to others.” Stimulus persons were broken down by sex and sex-typing—half were male, half female—and within sexes one third were classified as masculine, feminine, and androgynous on the basis of their scores on the Bem Sex Role Inventory. Two experiments are reported in which groups of judges rate stimulus persons on the basis of such different expressive information as videotaped pictures and recorded voices, videotaped pictures alone, videotaped bodies, videotaped heads, recorded voices, and still photos. The results showed: (1) Judges reliably rated masculinity-femininity from largely expressive cues: (2) judgments of masculinity-femininity were not predominantly determined by judgments of sex role-related traits: (3) the naive judgment of masculinity-femininity significantly corresponded to stimulus subjects' assessed sex roles; (4) stimulus subjects (particulary males) showed a consistent display of masculinity-femininity across expressive channels; and (5) judges used different expressive cues in judging masculinity-femininity in males and females. These results are related to broader questions concerning the relation between expressive behavior and personality.     

Effects of density,activity, and personality on environmental preferences

The effects of room density, type of ongoing activity (party vs studying), and a personality variable (“personal space” or the distance which subjects place between themselves and others) on room liking were investigated. Results supported the prediction that type of activity is an important determinant of whether a high or low density setting is preferred. Evidence was also presented that a mediator between activity type and density preference is whether the presence of other people facilitates or inhibits the individual's goals in the setting. Personality factors also influence density preferences: Close standing Ss preferred a high to a low density setting; far standing Ss showed an opposite preference pattern, but only in the party condition. Correlations between Ss' personal space scores and several background and personality variables are also presented.     

Deep and surface structure in children's sentence learning

Fifth-graders were asked to learn 32 syntactically varied, semantically unrelated sentences containing combinations of agentive, objective and instrumental case relations. Five learning trials, each followed by a noun-prompted recall test, were provided. Recall patterns indicated that variations in surface structure complexity (i.e., verb voice and sentential position of noun prompts) exerted less influence on Ss' memory for sentences than deep structures. Several trials were required for Ss to reproduce syntactic details accurately and many transformational errors were observed. Even then, children were unable to learn one syntactic form. Although patterns of recall were more consistent with deep structure predictions, results were not completely supportive of Fillmore's analysis of deep structure in terms of case relations, and the possibility that other non-linguistic means were used to store sentences loomed as an alternative to the deep structure view.     

The effect of partially valid cues on children's discrimination learning

Second grade children were administered a two-choice discrimination learning task in which irrelevant dimensions were correlated .50, .75, or 1.00 with the 100 percent rewarded cue. The results indicated that when a cue was partially correlated with reward .75, learning was retarded. When all cues were relevant and redundant (r = 1.00), learning was most rapid. These results supported an implication of Hypothesis Testing Theory that partially correlated or partially valid cues would not be eliminated rapidly, thus retarding acquisition of the correct response.     

Reward and number of choices in children's probability learning: An attempt to reconcile conflicting findings

Five event schedules (75:0, 75:25, 75:0:0, 72:25:0, 75:12.5:12.5) were examined in a size discrimination task with penny rewards and plastic token markers. The subjects were 100 fourth graders (mean age = 9.4 years) and 100 undergraduates of both sexes. Whether or not the event probabilities summed to unity proved to be a more important determiner of terminal performance than the number of response alternatives in the task (p < .01). Females maximized more than males (p < .001) and college students more than fourth graders (p < .001). Greater maximization was exhibited by fourth graders in the reward condition (p < .01). These reward effects appeared to be more consistent with a detrimental-effects-of-reward interpretation than either utility or expectancy interpretations.     

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.     

Androgyny,sex-typing,and the perception of masculinity-femininity in handwritings

Sex-typed and androgynous subjects rated the similarity of handwritings on masculinity-femininity and also rated the writings on an absolute scale of masculinity-femininity. The variances of sex-typed subjects' ratings were significantly higher than those of androgynous subjects, indicating that sex-typed subjects differentiated more along the dimension. Sex-typed subjects also agreed more highly with other raters and among themselves than did androgynous subjects. Multidimensional scaling of similarity ratings—using nonmetric multidimensional scaling (Kruskal, 1964; Shepard, 1962), and INDSCAL (Carroll & Chang, 1970)—showed interpretable dimensions along which subjects perceived masculinity-femininity. Further scaling solutions indicated again that sex-typed subjects differentiated more strongly along the dimension of masculinity-femininity and weighted the dimension more highly in making their similarity ratings. The data supported the hypothesis that subjects who monitor their own behavior on a given dimension are more sensitive to cues in others relating to that dimension.     

Neonatal sucking: Effects of quantity of the response-contingent fluid upon sucking rhythm and heart rate

The temporal organization of neonatal nutritive sucking and heart rate were studied in two consecutive 4-min periods to analyze the effects of two quantities of response-contingent fluid. One group of newborns experienced only the larger amount, a second experienced the smaller, and two other groups experienced both in counterbalanced order. Cumulative pausing time and intersuck intervals (sucking rate within bursts) were both affected by the amount of fluid delivered at each response. At the start of sucking bursts, heart rate accelerated to a stable level. Within-burst heart rates were higher with increased quantity of contingently delivered fluid. The results are discussed in relation to the distinction between nutritive and nonnutritive sucking and to previous findings on the effects of fluid sweetness upon sucking.     

Self-control and choice in humans: Effects of video game playing as a positive reinforcer

Participants chose between reinforcement schedules differing in delay of reinforcement (interval between a choice response and onset of a video game) and/or amount of reinforcement (duration of access to the game). Experiment 1 showed that immediate reinforcement was preferred to delayed reinforcement with amount of reinforcement held constant, and a large reinforcer was preferred to a small reinforcer when both were obtainable immediately. Imposing a delay before the large reinforcer produced a preference for the immediate, small reinforcer in 40% of participants. This suggested a limited degree of “impulsivity.” In Experiment 2, unequal delays were extended by equal intervals, the amounts being kept equal. Preference for the shorter delay decreased, an effect that presumably makes possible the “preference reversal” phenomenon in studies of self-control. Overall, the results demonstrate that video game playing can produce useful, systematic data when used as a positive reinforcer for choice behavior in humans.     

Extent,multiplying, and proportionality rules in children's judgments of area

The study examined children's use of multiplying and proportionality rules in judgments of area. In two experiments children judged the area of rectangles. Seven-year-olds used linear extent as an index of area. Eight- and nine-year-olds replaced the extent rule with the height × width rule. In a third experiment 8-through 11-year-olds were presented with a rectangle and a horizontal line representing the width of a second rectangle. Children were asked to indicate the height that would make the second rectangle equal in area to the first. The correct response was proportional to the product of the ratio of the widths of the two rectangles and the height of the first rectangle. Graphical and statistical analyses indicated that children applied the ratio rule to these judgments. The implications for Piaget's theory of cognitive development were discussed.     

Negative reinforcement and choice in humans

Participants chose between reinforcement schedules differing in delay and/or duration of noise offset. In Experiment 1 it was found that (1) immediate reinforcement was preferred to delayed reinforcement when amounts (durations) of reinforcement were equal; (2) a relatively large reinforcer was preferred to a smaller one when both reinforcers were obtained immediately; and (3) preference for an immediate, small reinforcer versus a delayed, large reinforcer increased as the delay preceding the large reinforcer increased, a sign of “impulsivity”. In Experiment 2, the schedules differed in amount or delay and equal intervals were added either to the constant parameter or the varied parameter. A shift from virtually exclusive preference to indifference occurred in the latter case but not the former, a result supporting a model of self-control that assumes that the value of a schedule depends on the ratio of amount and delay, and that choice between schedules depends on the ratio of these values.     

Sexual arousal and interpersonal evaluations

In an attempt to reconcile conflicting results concerning the effects of sexual arousal on interpersonal evaluations, hypotheses based on adaptation level, arousal-need gratification, and labeling of arousal explanations were tested. The variables of sexual arousal, technique of stimulus material presentation, physical attractiveness of the original stimulus female, and physical attractiveness of the final target person being judged were manipulated in a 2 × 2 × 2 × 2 design. A significant three-way interaction (Arousal × Stimulus Attractiveness × Target Attractiveness) obtained on all measures of interpersonal evaluation was interpreted as supporting a labeling of arousal explanation. It is suggested that subjects first interpret their arousal as being caused by their attraction toward the stimulus person. The characteristics of the stimulus person then become a factor used by subjects when they subsequently make judgments of target females. The adaptation-level and arousal-need gratification hypotheses were not supported.     

The effects of exemplary and cognitive models and self-rehearsal on children's interrogative strategies

Children aged 6, 8, and 10 years were exposed to three types of training procedures aimed at increasing their use of constraint-seeking questions and enhancing their problem-solving efficiency. One group observed an exemplary model who merely illustrated several constraint-seeking questions. Another group observed a cognitive model who, prior to asking each of her constraint-seeking questions, verbalized her strategy for formulating constraint-seeking questions and integrating the information gained from such questions. A third group received a combination of cognitive modeling and self-rehearsal training in which the children repeated statements representing key features of the constraint-seeking strategy before asking questions on a series of training items. Cognitive modeling alone was the most successful training procedure, effecting changes in both constraint-seeking questioning and problem-solving efficiency for children of all three age groups. Differences between cognitive and exemplary models were most notable among the youngest children, who appeared to require the additional guidance afforded through the verbalizations of the cognitive model.     

Image tracing: An analysis of its effectiveness in children's pictorial discrimination learning

Previous research has shown that requiring children to trace from memory the correct member of a pictorial discrimination pair markedly facilitates performance. The experiment reported here offers support for a presumed component of this learning strategy, namely, “memory imagery.” In particular, subjects who traced directly on top of the correct picture did not perform as well as those who traced it from memory. Various theoretical explanations of the image-tracing phenomenon are considered, including depth of processing, dual coding, and frequency.     

Need for uniqueness,self-schemas,and thought as moderators of the false-consensus effect

L. Ross and his colleagues (L. Ross, D. Greene, & P. House, 1977, Journal of Experimental Social Psychology, 32, 880–892) have demonstrated the tendency for people to expect peer similarity in behavior, termed the “false-consensus” bias. The present study was concerned with factors that might affect the generality of this bias. Specifically, we looked at the impact of level of need for uniqueness (C. R. Snyder & H. L. Fromkin, 1977, Journal of Abnormal Psychology, 5, 518–527), existence of a self-schema (H. Markus, 1977, Journal of Personality and Social Psychology, 35, 63–78), and thought on expectations of peer similarity. It was predicted that thought would polarize the estimates of high and low N Uniq individuals in opposite directions, but only when the individual possessed a self-schema along the relevant behavioral dimension. The results for behaviors reflecting independence supported this prediction. Discussion centered around limits of the false-consensus bias, along with consideration of the complexities involved in the link between availability factors and interpersonal judgments.     

Children's use of perceptual set

The effects of perceptual set and of “sequential visual noise” on the identification of briefly exposed pictures were examined in 5-year-olds, 8-year-olds, and adults. Subjects were asked to indicate whether a brief target matched a standard. The standard picture was presented either before the target picture (to establish a set) or after the target. The target was presented either alone or last in a series of six brief pictures (i.e., in noise). Adults and 8-year-olds were at ceiling when the target was presented alone, but set facilitated their identification of the target in noise. The 5-year-olds benefited from set both when the target was presented alone and when it was presented in noise. These findings suggest that set for a specific target picture functions similarly at all ages.     

The effects of self-monitoring on the expressive display of masculinity-femininity

Do self-monitoring processes influence (1) the correspondence between assessed personality and expressive masculinity-femininity, and (2) the cross-channel consistency (face, body, voice) of expressive masculinity-femininity? To answer these questions, 36 male and 36 females completed the Bem Sex-Role Inventory (BSRI) and Snyder's Self-Monitoring Scale, and then were videotaped as teachers. Five groups of naive judges rated these stimulus subjects on expressive masculinity-femininity, basing their respective ratings on: video pictures and voices, just pictures, just faces, just bodies, or just voices. A sixth group of judges rated subjects on physical attractiveness. The results indicated that judged physical attractiveness was significantly correlated with judged masculinity-femininity, with men being judged more masculine and females more feminine the more attractive they were. BSRI femininity correlated strongly with judged masculinity-femininity, and BSRI masculinity, less so. Finally, self-monitoring did prove to moderate the correspondence between personality and expressive behavior, and the cross-channel consistency of masculinity-femininity cues: however, these moderating effects were different for males and females.
