Intensional and extensional analogy items: Differences in performance as a function of academic major and sex

Is there a relationship between academic field and ability to use different types of semantic relation? Performance on two types of analogy item in the Graduate Record Examination (GRE) General Test was compared. Intensional relations are inherent in the meanings of the words and are based on shared or contrasting properties (e. g. farmer:person, breeze:gale, alive: dead, beggar: poor). Extensional relations reflect empirical relations between things in the world and are based on contiguity or causality (e. g.farmer:tractor, road:sidewalk, flu:headache). Performance on the two kinds of analogy items was compared for a single administration of the GRE for English and History majors (verbal group, n = 2238) and electrical engineering, computer science, and mathematics majors (practical group, n = 2143). The verbal group did better on intensional, and the practical group did better on extensional analogies. The difference was not explained by a correlated gender difference by which women did better on intensional and men did better on extensional items. Thus differences in the ability to use intensional and extensional relations was related to academic training, although the direction of this relationship was not established.     

A review of observer reactivity in adult-child interactions

The present article reviews studies which have examined the question of observer reactivity in adult-child interactions. Seventeen studies were located. Studies were classified according to the paradigm used to examine reactivity, the setting in which the study was conducted, the identification of the child as a behavior problem, and the occurrence and direction (i.e., increases or decreases in the observed behavior) of reactivity. The results indicated that the awareness paradigm has been employed most frequently, the laboratory has been the primary setting utilized, and problem and nonproblem children have been employed with approximately equal frequency. Reactivity was reported in about three-fourths of the studies. For adults positive and neutral verbal and physical behaviors were more reactive than negative behaviors. The positive and neutral behaviors typically increased in the observer's presence. For children conclusions are not warranted at this time as too few studies have examined children's behavior.Preparation of this article was supported in part by NIMH Grant MH28859-01.     

The effects of legislative reform on civil commitment admission rates: A critical analysis

Many jurisdictions across North America have revised their statutes pertaining to the criteria for civil commitment with the legislative intent to either increase or decrease the use of involuntary hospitalization. The impact of these revised statutes has been examined in many jurisdictions, but there has been no consensus regarding their effectiveness in changing the rates of involuntary admissions. The present article reviews the literature from a methodological perspective, comparing the differing analyses, results and interpretations. When the legislative revision has sought to expand medical prerogative, results indicate a sustained increase in civil commitments. When legislation has aimed at limiting medical discretion, there was an immediate decline in civil commitment rates, but a subsequent increase in the period following the initial post-reform declines. These results are discussed in terms of readmission trends, deinstitutionalization, and the possible reaction of mental health professionals who perceive legislation as an unnecessary constraint in the treatment of the mentally ill.     

Androgyny,depression, and self-esteem in irish homosexual and heterosexual males and females

An examination was made of the following research questions: (a) Do Irish homosexuals and heterosexuals differ in the frequency of their classification in sex-role categories? (b) Is sexual orientation related to psychological adjustment? (c) Is androgyny related to psychological adjustment? Subjects were 112 Irish men and women who were administered Bem's Sex-Role Inventory, Rosenberg's Self-Esteem Scale, Zung's Self-Rating Depression Scale, and a questionnaire. Results indicated that Irish homosexuals were classified more frequently than Irish heterosexuals as androgynous. Homosexuals did not differ from heterosexuals in self-esteem or depression scores. Among these Irish subjects, psychological sex-role category is a more powerful influence on psychological health than actual sexual orientation. It is not whether you are homosexual or heterosexual that affects your psychological health, but how you perceive your own psychological masculinity and femininity.     

Sexual dysfunction in women sexually abused as children

Women who were sexually victimized as children report problems in relating to both men and women. Studies have found that victims are less satisfied with their current sexual relationships and with the quality of their relationships with men in general. Fear of sex, arousal dysfunction and desire dysfunction were the most common sexual disturbances found in incest victims.The purpose of this paper was to examine the differences in sexual functioning in abused women who perceived themselves to be adjusted to the trauma of their sexual abuse and those who did not.A sample of 57 nonclinical adult women who had been sexually abused as children was studied. Data were analyzed by means of cross-tabulation, chi square statistics, analysis of variance, and multiple regression.Orgasm was experienced by 63% of the women. There was a significant interaction among ability to be an orgasmic, sexual esteem and adjustment to abuse. Over 56% of the women experienced physical discomfort during intercourse and 36% indicated that they needed sex therapy. The implications of these and other findings are discussed.     

Sex differences in the lateralized processing of facial emotion

Two reaction time tasks were administered to male and female normal subjects, involving judgments of facial emotion. In the Word-Face task, judgments of similarity or difference of a centrally presented emotion word and an emotional face presented in the left or right visual field were required, and in the Face-Face task, comparisons of a centrally presented and a laterally presented emotional face were required. Results were significant for the matching trials only. Reaction times to negative emotions were faster overall than to positive emotions, and an Emotional Valence by Visual Field interaction was found such that reaction times were faster for negative emotions in the left visual field and for positive emotions in the right visual field. This interaction was significant for the female but not the male subjects, although similar patterns were observed in both sexes. Further, an interaction of Gender, Task, and Emotional Valence was found, such that the two tasks had opposite effects for the two sexes. The Face-Face task appeared to inhibit the performance of the male subjects and facilitate the performance of the female subjects in terms of reaction time. It was suggested that specifying the target emotion by an emotional face elicits a greater emotional response on the part of the subject than specification by a word, and that this emotional elicitation may result in a reactive inhibition in the male subjects and in an elaboration of the emotional response in the female subjects.     

Anagram solving: Does effort have an effect?

The purpose of these studies was to explore the role of effort in remembering anagrams and their solutions. In Experiment 1, we compared the effects on memory of copying words, typing them as solutions for easy anagrams, or typing them as solutions for difficult anagrams. Solving anagrams involved more effort than did simply typing words, as indexed by response time. However, this effort facilitated recall for solutions to easy anagrams but not for solutions to difficult anagrams. In Experiment 2, we compared memory for anagrams and their solutions using a frequency-judgment task. Memory for solutions was better than memory for anagrams, and this difference was not affected by anagram difficulty. The results of these studies have implications for our understanding of the role of effort in remembering.     

Separating response dependency and response-reinforcer contiguity within a recycling conjunctive schedule

A procedure is described which disrupts response-reinforcer contiguity and response dependency and which demonstrates how the location of the response dependency in interval schedules can be regarded as a controlling variable in its own right. Rats' lever pressing produced sucrose on a recycling conjunctive fixed-time 30-second fixed-ratio 1 schedule of reinforcement. Reinforcement occurred only at the end of the fixed-time component on this schedule and only if a response had occurred during that component. This produced a pause-respond-pause pattern during the interreinforcer interval for all animals. When the location of the response dependency was then restricted to a 10-second period in the middle of the fixed-time component, the pattern was accentuated and response rates increased for all animals, while postreinforcement pauses decreased sharply for two animals. When responding was required in the first 10 seconds of the fixed-time component, responding peaked earlier in the interval for all animals. Response rates were slightly below those in the previous conditions, while postreinforcement pauses were between 2 and 6 seconds across animals.     

Spatiotemporal continuity and the perception of causality in infants

Infant perception of a Michottean launching event in which one object causes another to move through collision is examined in a series of habituation-test experiments. A number of hypotheses concerning how infants aged around 30 weeks might perceive and encode launching and its noncausal variants are identified and tested. The results of the first experiment indicate that infants can perceive direct launching as an event with internal structure, that is, as composed of two temporally ordered movements. The nature of the encoding by the infants is perceptual and not specifically motor-based. The second experiment makes it seem unlikely that the infants encode independent spatial and temporal features (for example, contact and successivity), while the third experiment suggests a spatiotemporal continuity gradient. Some implications for the origins of causality are discussed.     

Childhood Psychosocial Predictors of Adulthood Smoking,Alcohol Consumption,and Physical Activity1

This study prospectively addresses whether aspects of the childhood home environment (SES and parental divorce) and personality are predictive of smoking, alcohol consumption, and physical activity in middle adulthood. Subjects were 972 males and females who participated in the Terman Life-Cycle Study. Results of hierarchical regression analyses indicated that childhood unconscientiousness, cheerfulness, and parental divorce predicted adult smoking. Childhood unconscientiousness and sociability predicted adult alcohol consumption. Physical activity was predicted by a higher energy/activity level in childhood. Results suggest that the previously found associations between childhood characteristics and health-related behaviors over shorter periods are not simply reflective of early experimentation with such behaviors, but may be indicative of long-term lifestyle patterns.
