Sex differences in educational outcomes: A cross-national study

Through their organization and curricula, schools either promote separate roles for males and females or operate to minimize differences. This study describes sex differences in science and reading achievement and attitudes for nationwide samples of 14-year-old children in the United States, Sweden, and England. There are largely the same sex differences in all three countries: Male and female pupils have similar reading skills, while girls have more positive reading habits; males outperform females in science, with the smallest difference observed for biology; males have more positive attitudes toward science, except that females believe science to be at least as important a topic as boys do. There is no noteworthy increase in sex distinctions with one more year of schooling, from grade 8 to grade 9. However, in English coeducational schools, girls show a deceleration in science and vocabulary achievement relative to their male peers. Girls in English one-sex schools exceed their male counterparts in reading and several science subjects. It is hypothesized that the role of successful female teachers and peers, and the absence of social pressure from boys, may facilitate girls' learning in these areas. A study is proposed of specific school practices and the ways in which they determine sex discrepancies.An earlier version of this article was presented to the annual meeting of the American Educational Research Association, San Francisco, April 1976.

Interference and facilitation effects of primes upon verification processes

Priming effects on sentence verification were investigated. The semantic relation of the prime and the probe, and the interval between prime and probe presentation (SOA), were varied for both ambiguous and unambiguous sentences. Reaction time to decide that a sentence was true or false was longer if the preceding prime was a word that was unrelated to the probe than if the prime was the word “blank.” In contradiction of Posner and Snyder’s (1975) claim that conscious processes develop slowly, this result was found at SOAs as short as 250 msec. Verification performance was facilitated for both sentence types when the prime word was the first of the to-be-presented probe sentence, but the magnitude of the facilitation effects depended upon the truth value of the probe, the associative strength of the subject and predicate of the probe sentence, and upon SOA. These findings indicate that priming affects the processing of relations among concepts in semantic memory, as well as the encoding of the probe.     

THE EFFECTIVENESS OF VERBAL INSTRUCTION ON TEACHING BEHAVIOR-MODIFICATION SKILLS TO NONPROFESSIONALS1

The effectiveness of a mastery criterion, lecture-based training program for teaching behavior modification to sheltered workshop personnel was evaluated. Staff performance was assessed in terms of: (1) verbal proficiency, as determined from a pre- and posttraining written exam, and (2) application proficiency, as measured by the frequency and appropriateness of staff responses to client behaviors. A direct count was made of the number of positive, negative, and neutral statements following client appropriate and inappropriate behaviors, and the number and type of client behaviors ignored. Thus, it was possible to determine the extent of generalization from classroom to applied settings, as well as the appropriateness of lectures for training specific performance skills. Lecture units introduced stimulus control procedures, shaping-chaining, and contingency management. Characteristic features of the training program were frequent testing, study objectives, immediate remediation, and contingent reinforcement. Verbal instruction was shown to be effective in improving subjects' verbal skills concerning behavior-modification principles, while only partially effective in improving application skills. There was an increase in the total number of staff-client interactions observed for all subjects, but only two of the response classes emphasized in the training program (reinforcing desirable client behavior and ignoring undesirable behavior) showed considerable improvement over pretraining levels. Despite this partial improvement, verbal instruction alone was shown to be insufficient for teaching the full range of behavior-modification skills required to function effectively in applied settings.     

Resistance to satiation of consummatory and instrumental performance

In three experiments rats received training in a straight alley under high hunger and then were tested satiated. Both eating and running continued to occur under satiation, but the two responses were not completely correlated, and continued running did not depend upon continued eating. Further, groups differed in their eating behavior, although all experienced the same satiation procedure, suggesting that eating under satiation is not just a reflection of incomplete satiation. Resistance to satiation of the running response was greater following partial reward than following consistant reward and tended to be greater following small reward training than large reward training, regardless of schedule of reward. Eating during satiation was greater following partial than following consistent reward and was greater if the same reward magnitude was given in satiation as in acquisition than if a different reward magnitude was given. It was suggested that resistance to satiation is an associative phenomenon. Eating and running occur during satiation because the stimuli present during satiation continue to elicit them. The differences between results using rewarded satiation and results using high drive extinction as measures of persistence were attributed to satiation being nonfrustrating.     

A method for obtaining single cell responses in the optic tract of self-respiring fish

This paper describes a preparation for recording action potentials from the central nervous system of an intact self-respiring fish. The cervical spinal cord of the anesthetized fish was lesioned to minimize body movements, and the brain was exposed by cutting a hole in the dorsal skull. A clamp was attached to the rostral edge of this hole to eliminate motion of the skull. The fish in this preparation can control its own respiration and thus maintain an essentially normal respiratory state. This is a significant improvement over previous preparations, as respiratory state has been shown to be an important determinant of central nervous system function.     

Field-dependence, sensation-seeking, and preference of paintings

College students (122 males and 88 females) completed the Group Embedded Figures Test measure of field-dependence, and Sensation-Seeking Scale, and performed preference ratings on 40 slides of paintings. Factor analysis revealed six hypothesized and one unhypothesized preference dimensions that underlay preference ratings of paintings. It was hypothesized that the cognitive structuring ability associated with field-dependence would result in certain relationships between field-dependence and preference for paintings. Further, it was hypothesized that preference for novel, complex, and dynamic experiences, associated with sensation-seeking, would result in certain relationships between sensation-seeking and preference for paintings. For the full sample, three of five hypothesized relationships between field-dependence and preference for paintings were obtained, while three of four hypothesized relationships were found between sensation-seeking and preference for paintings.     

Phobia and counterphobia: family aspects of agoraphobia

Twelve cases with agoraphobic and other phobic symptoms are presented. Their family backgrounds and marital relationships are delineated. A consistent pattern, the phobic-counterphobic system, emerges. This contains five elements. (1) Anxious ambivalent attachment, which characterizes the previous childhood relationships of both partners in the marriage. The future patient has responded to this with a tendency to clinging behaviour, her spouse with a propensity to detachment. (2) A marriage in which, initially, each, through the other, escapes from their childhood difficulties. (3) A precipitating change with challenges the couple's illusionary unity. (4) A period of escalation and failure of reassurance by the husband. (5) The illness, which stabilizes the system and leads to a 'compulsory marriage'. Therapeutic approaches for each of these elements are described.     

Issues to consider in the differential diagnosis of normal childhood nonfluencies and stuttering

Historically more attention has been focused on the adult stutterer than on the young stutterer. This article discusses three key issues in the differential diagnosis of normal childhood nonfluencies and childhood stuttering. The three issues are (1) whether early childhood disfluencies are heterogeneous or homogeneous phenomena, (2) whether the relationship between normal childhood nonfluencies and early stuttering is continuous or dichotomous, and (3) whether normal nonfluencies and stuttering differ quantitatively or qualitatively. Theoretical research as well as clinical implications of these issues are discussed.     

Reasoning Dialogues

When people argue with others in conversation, they make a variety of conversational moves: They make claims, ask for justification of others' claims, attack claims, and attack claims' justifications. The arrangement of these moves gives argumentation its characteristic shape. This article illustrates a proposed format for conversations of this type, and it reviews some findings about the way people understand and evaluate these conversations. The findings suggest that judgments of the arguers' burden depend not only on the content of their claims, but also on the conversation's structure. In addition, judgments of the strength of a justification—an arguer's evidence or explanation—are a function of the argument's setting.
