The effect of context on the structure of categories

Three experiments examined the effect of context on the representativeness ordering of exemplars of a category. Experiments 1 and 2 employed an online reading time paradigm to examine the effect of context on the time it takes to establish an anaphoric reference between an exemplar and a category term. Experiment 1 demonstrated that context can change the relation between a category term and an exemplar at the time of comprehension. Experiment 2 showed that category terms presented in context generate graded goodness-of-example distributions of exemplars that are different from the distributions generated in the absence of explicit context. These distributions cannot be derived by assuming that the exemplar most strongly suggested by the context serves as the category representation. Experiment 3 employed a membership verification paradigm. Response time was found to be a function of degree of relatedness to the contextdependent category representation. Typicality, as determined in the absence of explicit context, had no effect on decision time. Several models, including some extensions of current semantic memory theories, are developed to account for the results of these experiments.     

Building theories of reading ability: On the relation between individual differences in cognitive skills and reading comprehension

To date most theories of reading ability have emphasized a single factor as the major source of individual differences in performance. However there has been little agreement on what that factor is. However, candidates have included visual discrimination, phonological and semantic recoding, short-term memory, and utilization of linguistic knowledge and context. The single- factor theories are summarized. Literature is then reviewed to show that no single-factor theory is likely to be right, because a very wide range of component skills and abilities has in fact been shown to correlate with reading success. Among them are discrimination of letter location and letter order during perceptual recognition, use of orthographic regularity as an aid to visual code formation, use of spelling-to-sound regularity in phonological recoding, memory for word order, spontaneous identification of syntactic relations, flexibility in prediction from syntactic and semantic context, and context-specificity in semantic encoding. It is concluded that more complex, multifactor models of reading ability are required, and some recent attempts to collect data conducive to such a model are described. In the process, three different approaches to identifying factors relevant to reading success are delineated. These are general abilities assessment, learning potential assessment, and component skills analysis. Two methods of conducting component skills analysis are presented, and it is recommended that they be used as converging operations. Finally, the results of a component skills analysis are used to construct a tentative example of a class of hierarchical models of reading ability that can be pursued developmentally.     

Pressures from work,self, and home in the life stages of married women

Following Lopata's (1966) model of the life cycle of the married woman's role, it was predicted and found that a woman's life stage would be related to her role pressures (work, home, self, and time), conflict, and satisfaction. Age and number of roles were not as strongly related to these variables as was life stage. Work activities and pressures declined through the peak child-rearing stage and then increased for women with older children, while pressures from home generally rose throughout the life cycle. The differential impact of various sources of conflict in different life stages was reported, and forms of organizational career support oriented toward particular life stages were suggested.     

Occupational decision development over the high school years

This study described the development of occupational decision processes over the high school years. Five developmental trends derived from theory were examined separately for males and females in three rural schools. Growth was defined as increased frequency in classes of behavior from early 9th grade to late 12th grade. The key processes in occupational decision development for both sexes appeared to be an information search strategy and an elaborate rationale. Both processes increased in complexity and contributed to confident feelings about occupational choices in 12th grade. Implications for measurement of occupational decision processes and for developmental research are discussed.     

Vocational decision-making patterns among noncollege-aspiring adolescents

Vocational decision-making (VDM) behavior reported by noncollege-aspiring adolescents was measured by 32 indices derived from decision theory. Patterned differences were especially evident on indices assessing range of planning activities. Infrequent correlations were noted among indices representing each of five theoretical VDM dimensions. Cluster analysis grouped indices into four VDM clusters describing separate decision situations. A speculative model was developed to describe the relationship between VDM Clusters and performances variables. Hypotheses for later study were developed.     

Recall in preschool children

Free recall, cued recall, color recall, organization in recall, and sorting of 3- and 4-year-olds was assessed on 9-item lists of objects that were orthogonally varied on color and category dimensions. Half of the children in each age group were presented items successively, and the other half simultaneously. Older children recalled more items than younger children in both free and cued recall, and also organized their recall more. Moreover, simultaneous presentation benefited the older, but not younger children. Clustering and sorting data suggested a decreasing reliance on perceptual information, and increasing utilization of conceptual information, over the preschool years. The results were discussed in terms of the importance of concrete, external stimulus support at both time of encoding and retrieval.     

Paralinguistic aspects of auditory comprehension in aphasia.

Eight severe aphasics were given sentences with either emotional or neutral content, presented once directly by the examiner and once via a tape recorder. Sentences with emotional content produced a greater number of responses than their neutral counterparts. Sentences spoken by the examiner also produced a significantly greater number of responses than the same items originating from a tape recorder. These results confirm the view that elements not related to the linguistic aspects of a message (and therefore referred to as paralinguistic) play a significant role in auditory comprehension.     

Suggestibility and type of interpersonal relationship: Special implications for the patient-practitioner relationship

Suggestibility was assessed in five conditions by the subject's response to suggestions falsely labeled as matters of fact. These misrepresentations of fact, or virtual suggestions, denoted a variety of hallucinations, an anesthesia, and an amnesia. They were administered as incidental intrusions while the subject was involved in the primary experimental task. In three of these conditions, the subject either observed his own spontaneous visual imagery, observed visual scenes provided by the experimenter, or simply waited with closed eyes for the presentation of the virtual stimuli. These conditions were characterized by a passive-receptive, interpersonal relationship in which the subject remained silent. Suggestibility was expected to be high. In a fourth condition the subjects described spontaneous visual imagery. This was characterized as an active-receptive relationship in which speech was maintained throughout. The suggestibility of the three passive-receptive conditions was comparable, and none of them differed from a baseline condition involving the formal induction of hypnosis. However, the fourth, active-receptive condition was significantly lower, and this difference survived a replication. Of special interest was the induction of an anesthesia in the majority of subjects in the three passive-receptive conditions.     

Behavioral confirmation in social interaction: From social perception to social reality

A perceiver's actions, although based upon initially erroneous beliefs about a target individual may channel social interaction in ways that cause the behavior of the target to confirm the perceiver's beliefs. To chart this process of behavioral confirmation, we observed successive interactions between one target and two perceivers. In the first interaction, targets who interacted with perceivers who anticipated hostile partners displayed greater behavioral hostility than targets whose perceivers expected nonhostile partners. Only when targets regarded their actions as reflections of personal dispositions did these behavioral differences in hostility persevere into their subsequent interactions with naive perceivers who had no prior knowledge about them. Theoretical implications of the behavioral confirmation construct for social perception processes are discussed.
