Assessment of peer rejection and externalizing behavior problems in preschool boys: a short-term longitudinal study

We examined the longitudinal stability of measures of negative peer status and aggressive-disruptive behavior in preschool boys. Subjects were 53 white 4- to 5- year- old boys from low-income family backgrounds. Peer sociometric measures of rejection and behavioral deviance were assessed in the fall and spring of the preschool year. Complementary measures were also obtained from teachers at both assessment points. Half of the boys designated as rejected on the basis of peer nominations maintained this status at the end of the preschool year. Teachers and peers did not agree on their selections of socially rejected children, but had good agreement concerning the identification of children with externalizing-type behavior problems. Finally, teacher and peer classifications of aggressive-disruptive children were highly stable throughout the preschool year. These findings indicate that peer-rejected children can be identified at very young ages, and that preschoolers can be reliable informants about the social maladjustment of peers.We thank the Head Start children, parents and staff who participated, and Karen Lifgren for her help with data collection.     

Sensitivity to pictorial shape perspective in 5-year-old children and adults

Five-year-old children’s and adults’ sensitivity to shape perspective was tested with relative length judgments of two crossed lines on the surface of a tilted “box.” The stimuli were presented in both slides and three-dimensional viewing conditions. Judgments in the three-dimensional condition corresponded closely to the actual three-dimensional lengths. Responses in the slide-viewing condition were similar for both age groups, and showed about a one-third regression toward picture-plane length judgments. The lack of age effects was considered with respect to theories of the development of sensitivity to shape perspective.     

Loneliness among Japanese and American college students

Both Japanese and American college students (ns = 100), away from home at their first year in college, showed high scores in the Differential Loneliness Scale, with Japanese students scoring higher on all subscales.     

Preattentive processing or prefocal processing?

The concept of preattentive processing is analyzed and alternative views of it are presented. A basic question is whether processing required for preattentive input selection is qualitatively different from post-selection processing. In order to study this, subjects were presented in one set of conditions with one stimulus at either of two locations, and in another set of conditions, simultaneously with two stimuli. The stimuli could be green or red, or large or small. Subjects were asked to indicate the location (or the color, or the size) of the single stimulus in the single-stimulus conditions, or of a predesignated stimulus (say, the red one) in the dual-stimulus conditions. Responses were generally slower in the dual-stimulus conditions. The increases in reaction time were accounted for by the times it takes to process for response selection the properties by which the target stimulus could be selected, as indicated by the results of two control conditions. The results as well as some other considerations do not support the view that preattentive processing is necessarily of a type that qualitatively differs from post-selection processing.     

The Utility of Cognitive Plausibility in Language Acquisition Modeling: Evidence From Word Segmentation

The informativity of a computational model of language acquisition is directly related to how closely it approximates the actual acquisition task, sometimes referred to as the model's cognitive plausibility. We suggest that though every computational model necessarily idealizes the modeled task, an informative language acquisition model can aim to be cognitively plausible in multiple ways. We discuss these cognitive plausibility checkpoints generally and then apply them to a case study in word segmentation, investigating a promising Bayesian segmentation strategy. We incorporate cognitive plausibility by using an age‐appropriate unit of perceptual representation, evaluating the model output in terms of its utility, and incorporating cognitive constraints into the inference process. Our more cognitively plausible model shows a beneficial effect of cognitive constraints on segmentation performance. One interpretation of this effect is as a synergy between the naive theories of language structure that infants may have and the cognitive constraints that limit the fidelity of their inference processes, where less accurate inference approximations are better when the underlying assumptions about how words are generated are less accurate. More generally, these results highlight the utility of incorporating cognitive plausibility more fully into computational models of language acquisition.     

Effects of test-wiseness training on test anxiety,locus of control and reading achievement in elementary school children

Abstract

Fifth and sixth grade children were randomly assigned to either a control or an experimental condition in a pretest, posttest, delayed posttest design. The experimental group received instruction and practice in test-taking, and the control group received a placebo treatment. Dependent variables were four components of test anxiety, locus of control and achievement. Factor analysis of pretest data supported I. Sarason's four-factor conceptualization of test anxiety (worry, test-irrelevant thinking, tension, and bodily reactions to test taking). Posttest data generally supported the hypothesized treatment effects. As predicted, children in the experimental condition had higher reading scores, greater internality, and less test-irrelevant thinking. The delayed posttest scores indicated a diminished effect on the achievement and internality measures; however, the amount of test-irrelevant thinking remained lower in the experimental condition.     

Majority versus minority influence: the role of message processing in determining resistance to counter‐persuasion

Two experiments examined the extent to which attitudes changed following majority and minority influence are resistant to counter‐persuasion. In both experiments participants' attitudes were measured after being exposed to two messages, delayed in time, which argued opposite positions (initial message and counter‐message). In the first experiment, attitudes following minority endorsement of the initial message were more resistant to a second counter‐message only when the initial message contained strong versus weak arguments. Attitudes changed following majority influence did not resist the second counter‐message and returned to their pre‐test level. Experiment 2 varied whether memory was warned (i.e., message recipients expected to recall the message) or not, to manipulate message processing. When memory was warned, which should increase message processing, attitudes changed following both majority and minority influence resisted the second counter‐message. The results support the view that minority influence instigates systematic processing of its arguments, leading to attitudes that resist counter‐persuasion. Attitudes formed following majority influence yield to counter‐persuasion unless there is a secondary task that encourages message processing. Copyright © 2007 John Wiley & Sons, Ltd.     

Caffeine, Cognition, and Persuasion: Evidence for Caffeine Increasing the Systematic Processing of Persuasive Messages

Caffeine is known to increase arousal, attention, and information processing–all factors implicated in facilitating persuasion. In a standard attitude-change paradigm, participants consumed an orange-juice drink that either contained caffeine (3.5 mg/kg body weight) or did not (placebo) prior to reading a counterattitudinal communication (anti-voluntary euthanasia). Participants then completed a thought-listing task and a number of attitude scales. The first experiment showed that those who consumed caffeine showed greater agreement with the communication (direct attitude: voluntary euthanasia) and on an issue related to, but not contained in, the communication (indirect attitude: abortion). The order in which direct and indirect attitudes were measured did not affect the results. A second experiment manipulated the quality of the arguments in the message (strong vs. weak) to determine whether systematic processing had occurred. There was evidence that systematic processing occurred in both drink conditions, but was greater for those who had consumed caffeine. In both experiments, the amount of message-congruent thinking mediated persuasion. These results show that caffeine can increase the extent to which people systematically process and arc influenced by a persuasive communication.
