Metalinguistic awareness and language development

Thirty-six 3- and 4-year-old children were given a battery of six metalinguistic tasks and two measures of language development: the Peabody Picture Vocabulary Test and a sentence comprehension test. The results clearly showed that the majority of preschoolers were able to make at least some metalinguistic judgments, and that metalinguistic performance improved with age. Furthermore, overall performance on the metalinguistic tasks was significantly correlated with each language measure when the effects of age were partialed out. In contrast, the correlation between age and metalinguistic performance was not significant once the effects of both language measures were partialed out. These data demonstrate that preschoolers' metalinguistic abilities are more extensive than has been previously acknowledged, and that they are closely tied to other aspects of language development at this time.     

Dual effects of response blocking following avoidance learning

It was shown that either enhanced or decreased avoidance responding by rats could be produced by the same response blocking procedure occurring after avoidance training. The particular result produced depended on (1) the duration of the blocking trial and (2) when during the retention interval the blocking trial occurred. Results were interpreted in terms of a memory reactivation explanation and implications for the therapeutic uses of extinction were discussed.     

Affective and cognitive mediators of reactions to spatial invasions

At a crosswalk on a busy street, a confederate, sketching a drawing or not, stood close or far from a pedestrian for 10 sec before the street light indicated “Walk.” In the first study, pedestrians were given the opportunity to subsequently help this confederate or another accomplice by calling attention to a dropped pen. In the second study, crossing speeds were timed and pedestrians were asked to record their mood and reactions to “another pedestrian,” who happened to be the confederate. These studies tested and found evidence for both cognitive and arousal explanations of reactions to spatial invasions. Cognitive and attributional theories imply that characteristics of the invader are important mediators of reactions to the invasion. The close nonartist was judged to be more inappropriate, produced faster escape speeds, and was helped less than the close artist or the far confederates. Arousal explanations imply that any invasion produces a generalized reaction which would be unrelated to characteristics of the invader. The other accomplice was helped less when the subject had been invaded and this reduction in helping was unaffected by the artist manipulation. These findings suggest a general arousal response to any invasion with a subsequent reliance on cognitive interpretations.

Predicting Perceptions of Victimization

Male and female subjects rated female victims of misfortune after observing videotapes of the victims detailing their injuries to doctors. Contrary to predictions of just wortd theory, subjects derogated culpable victims more than innocent victims. When observers identified with the victim, through political ties, derogation was reduced. It was concluded that responses to victims are described by a balance theory framework in which the observer's relationships to the victim and the victimizing agent determine whether (s)he will react to victims with sympathy or derogation. It was further concluded that these relationships can be predicted from an understanding of the social and political context shared by the perceiver and the victim.     

Role and justice considerations in the attribution of responsibility to a rape victim

This study was designed to assess the extent to which social role and “just world” considerations would affect perceptions and attributions of responsibility to a rape victim. The rape victim was either a topless-bottomless dancer, a social worker, or a Catholic nun, and she was either acquainted or unacquainted with her assailant. In the acquainted condition, the dancer was attributed the greatest and the nun the least amount of responsibility, indicating that social role factors can govern the range of attributional judgments which might be made in any given instance. However, unacquainted victims were ascribed more responsibility for the rape than were acquainted victims, a difference which was significant when the victim was the nun. The latter findings are discussed in terms of Lerner's just world hypothesis. Significant sex differences were found in subjects' perceptions of and responses to the rape incident and, contrary to earlier findings, no relationship was found between victim attractiveness and punitiveness toward the wrongdoer.
