Effects of constraint and validity of sentence contexts on lexical decisions

Recent models of sentence context effects predict that the pattern of facilitation and inhibition of response to sentence completions should be influenced by the experiment-wide contextual “environment.” In the present experiments, this environment was manipulated in several ways, including the degree to which contexts constrained possible completions, the probability of predictable completions’ being presented, and the probability of congruous completions’ being presented. In Experiment 1, decreasing the proportion of congruent test words had no effect on either the facilitation for highly likely words or the inhibition for incongruent words; increasing the proportion of predictable words produced no increase in facilitation for these words, but did increase the inhibition for incongruous words. In Experiment 2, contexts with very high or very low degrees of constraint produced equivalent results when predictability was uniformly low: no facilitation for unlikely but congruent words, and inhibition for incongruent words. In general, the patterns of change in facilitation and inhibition caused by changes in the contextual environment were more consistent with the modified two-process model (Stanovich & West, 1983) than with the verification model (Becker, 1982). But the limited range of influence suggests that, under conditions approximating normal reading, little use is made of such “metacontextual” information.     

CF carrier testing: Experience of relatives

Consensus exists that genetic counseling and CF carrier testing should be offered to individuals with a positive family history of CF. To learn more about their experience with genetic counseling and testing we conducted a series of structured telephone interviews and focus group discussions with individuals and couples who had undergone genetic counseling and carrier testing because of a family history of CF. Traditional genetic counseling appears to have been effective for this population. Subjects generally report having a positive counseling experience and few difficulties upon learning their carrier status. Subjects were quite knowledgeable about CF and their carrier risk and were highly motivated to seek testing. They may not be representative of all individuals with a family history of CF however. For carriers, concerns about whether and when to have children tested, and concerns about insurance implications of carrier status may emerge sometime after the initial counseling. Strategies for addressing these concerns and for providing efficient and effective education and genetic counseling for people with a family history of CF need to be developed.     

A Feminist Reading of Men's Health: Or, When Paglia Speaks, the Media Listens

In this paper Bloom analyzes the popular magazine, Men's Health, from a feminist perspective, locating ways that the magazine participates in an insidious form of anti-feminist backlash. She specifically analyzes the magazine to make sense of how its writers discursively position women in their relationships to heterosexual men and how they use the voices of women who call themselves feminists to promote an anti-feminist, pro-patriarchy agenda. She demonstrates that the “health” of men being promoted in this magazine is a mental health grounded in the maintenance of male privilege and power.     

Relationship between intellectual status and reading skills for developmentally disabled children

The relationship between WISC-R Full Scale IQ and scores on the Woodcock Reading Mastery Tests were explored for 80 developmentally disabled children. While the children's reading skills correlated moderately and significantly with intellectual status, abstract reading skills, e.g., word comprehension, correlated more highly with Full Scale IQ than did concrete ones, e.g., word identification. The development of concrete learning patterns by such children was discussed, with an emphasis on the emotional importance of these learning styles to the children and their families.     

The interactive effects of locus of control and situational stress upon performance accuracy and time

The present paper sought to clarify the conceptual relationship between expectancy for personal control, stress, and behavioral reactions to stress. Expectancy for control was assessed as a personality characteristic of internal control; stress was experienced as strong environmental interruptions, disturbances, and unpredictable obstacles encountered during the performance of assigned tasks. Subjects were junior high school aged students who attempted to complete three academic type tasks during one of two levels of stress or a base line, no stress, condition. Analyses of the data included: (a) internal subjects were capable of sustaining task performance under high stress, but external students experienced performance decrements as stress increased; (b) time to complete the mathematics task reflected a facilitating effect of stress for internals but a debilitating effect for externals; (c) performance differences between internal and external students, in the absence of differences in reported anxiety, could be attributed to the stronger reward expectancies possessed by the internal individual. Interpretation of the data suggested an interactive relationship between type of stress (threat to ego vs. threat to instrumental performance) and expectancy for control in the influencing of behavior reactions to stress.

Patterning of infant vocal behavior

Three-month-old infants received two consecutive 5-minute periods of adult social stimulation. In both periods the adult talked, smiled, and touched the infant and in a natural manner tried to elicit vocalizations from the infant. In the first period the adult became unresponsive for 5 sec contingent upon each infant vocalization (time-out, negative reinforcement). In the second period the infant received the same number of time-out periods at the same intervals but independently of vocal responding (yoked, noncontingent control). Negative reinforcement did not suppress infant vocal rate, but the contingent withdrawal of social stimulation did cause the infant to pause more frequently between vocal responses. These pauses generally occurred immediately after the contingently, as compared with the noncontingently, delivered time-out period. The infant appears to recognize the difference between contingent and noncontingent stimulation and pauses after the occurrence of the former. Adult social reinforcement changes the pattern and not the rate of infant vocal responding.     

Intention and Analogy in Children's Naming of Pictorial Representations

What underlies children's naming of representations, such as when they call a statue of a clothespin "a clothespin"? One possibility is that they focus exclusively on shape, extending the name "clothespin" only to entities that are shaped like typical clothespins. An alternative possibility is that they extend a word that refers to an object to any representation of that object, and that shape is relevant because it is a reliable indicator of representational intent. We explored these possibilities by asking 3- and 4-year-olds to describe pictures that represented objects through intention and analogy. The results suggest that it is children's appreciation of representation that underlies their naming; sameness of shape is neither necessary nor sufficient. We conclude by considering whether this account might apply more generally to artifacts other than pictorial representations.
