Word age-of-acquisition and lexical decision making

This paper reports two experiments concerning the effects of word age-of-acquisition and other word attributes on speed of lexical decision. Analyses of group average data indicated that word length, frequency and familiarity were the major determinants of decision speed. Previous reports of age-of-acquisition effects on lexical decision are attributed to failures to control for word familiarity.     

Fear of success,sex role attitudes,and career salience and anxiety levels of college women

This study examined, for 99 female undergraduate students, both the relationship between fear of success, sex role attitudes, and career salience, and the relationship between fear of success, career salience, and trait anxiety. Fear of success was assessed using the Fear of Success Scale, while sex role attitudes were assessed using the Attitudes towards Women Scale. Career Salience was measured by the Career Salience Scale, and trait anxiety was assessed by the trait subscale of the State-Trait Anxiety Inventory. The results indicated that fear of success and sex-role attitudes, in combination, significantly predicted the level of career salience in a multiple regression analysis. The women higher in fear of success and more traditional tended to be lower in career salience. Trait anxiety levels of women did not differ significantly as a function of fear of success, career salience, or the combination of the two.     

Analogical problem solving

The use of an analogy from a semantically distant domain to guide the problemsolving process was investigated. The representation of analogy in memory and processes involved in the use of analogies were discussed theoretically and explored in five experiments. In Experiment I oral protocols were used to examine the processes involved in solving a problem by analogy. In all experiments subjects who first read a story about a military problem and its solution tended to generate analogous solutions to a medical problem (Duncker's “radiation problem”), provided they were given a hint to use the story to help solve the problem. Transfer frequency was reduced when the problem presented in the military story was substantially disanalogous to the radiation problem, even though the solution illustrated in the story corresponded to an effective radiation solution (Experiment II). Subjects in Experiment III tended to generate analogous solutions to the radiation problem after providing their own solutions to the military problem. Subjects were able to retrieve the story from memory and use it to generate an analogous solution, even when the critical story had been memorized in the context of two distractor stories (Experiment IV). However, when no hint to consider the story was given, frequency of analogous solutions decreased markedly. This decrease in transfer occurred when the story analogy was presented in a recall task along with distractor stories (Experiment IV), when it was presented alone, and when it was presented in between two attempts to solve the problem (Experiment V). Component processes and strategic variations in analogical problem solving were discussed. Issues related to noticing analogies and accessing them in memory were also examined, as was the relationship of analogical reasoning to other cognitive tasks.     

Sign-tracking in aversive conditioning

Two experiments were conducted to determine if rats tend to avoid contact with a stimulus that signals the occurrence of shock and contact a stimulus that signals the nonoccurrence of shock. The conditioned stimulus was a 60-sec platform presentation, and the unconditioned stimulus was a 2-sec inescapable shock. In each experiment, the emphasis was on two types of Pavlovian pairings: forward pairing in which each platform presentation was followed by shock, and backward pairing in which each platform presentation was preceded by shock and followed by a lengthy shock-free interval. Experiment 1 showed that in comparison with Random and CS-only procedures, the backward procedure produced a significant increase in approach and contact with the platform, but the forward procedure failed to produce a significant decrease in contact with the platform. Experiment 2, in which all groups were roughly equated for baseline levels of platform preference, demonstrated strong effects of both forward and backward conditioning. The experiments provide evidence for an aversive sign-tracking system in which animals' tendencies to withdraw from or approach and contact a platform CS are determined by the Pavlovian contingencies which render it a reliable signal for the occurrence or nonoccurrence of shock.     

Feature analysis and the token test

In a picture-matching task pictures of objects had to be arranged into pairs by aphasic and nonaphasic patients and normal controls. Aphasic patients were also given the Token Test. Correlation between the rank order of error scores in both tests was highly significant in aphasic patients. The pictures were also given to a normal group for free matching. Overlapping of normal performance on free matching and aphasic performance on bound matching occurred. We hypothesized that aphasic impairment was due to a difficulty in calling up associations, difficulty in feature analysis, and in moving from one concept to another. These findings are discussed in the light of abilities needed for Token Test performance. The results indicate that the traditionally presumed fundamental difference between verbal and nonverbal cognitive tasks is rather unsatisfactory.     

Relationships between locus of control,health value,and preventive health behaviors among women

This study examines the relationships between locus of control expectancies, rated health value, and reported participation in preventive health behaviors among a healthy sample of undergraduate women. The prediction that participation in preventive health behaviors would be a joint function of an internal health-related locus of control belief and holding health in high value was not supported. Instead, individuals who valued their health reported participating in a greater number of health-enhancing behaviors compared to those who valued their health less. Respondents' scores on a health value scale in combination with their rated health status proved to be better predictors of health behaviors than their locus of control beliefs. Limitations of locus of control research with young, healthy individuals are discussed and further investigation into the utility and validity of health value scales is recommended.     

An investigation of the nomological network of social interest

This paper presents the results of three studies relating a composite measure of social interest to numerous variables within the nomological network of social interest. Study 1 found that social interest is positively related to sex-role femininity, androgyny, positive ambition, other-centered life goals, and, surprisingly, sex-role masculinity. Study 1 also found social interest negatively related to a narcissistic life goal, personality rigidity, and negative interpersonal behavior (Drivenness). Study 2 correlated social interest with the Personality Research Form and found, as expected, that social interest is correlated with the Affiliation and Nurturance scales. Unfortunately, social interest was not negatively related to Aggression. Finally, Study 3 provided generally positive support for the hypothesized relationships between social interest and several variables from the Life Styles Inventory (e.g., Humanism, Affiliation, etc.). Implications of the results for the construct validity of Adlerian social interest theory and current measurement of social interest are presented.     

Embodied AI, Creation, and Cog

This is a reply to comments on my paper Cog, a Humanoid Robot, and the Questions of the Image of God ; one was written by Mary Gerhart and Allan Melvin Russell, and another one by Helmut Reich. I will start with the suggested analogy of the relationship between God and us and the one between us and the humanoid robot Cog and will show why this analogy is not helpful for the dialogue between theology and artificial intelligence (AI). Such a dialogue can succeed only if both our fascination for humanoids and our fear of them are equally accepted. Any avoidance of these emotions, as well as any rejection of the possibility that Cog might one day be humanlike, destroy the dialogue. The interpretation of both scientific theories and religious metaphors as stories replaces seemingly "rational" arguments with the confession of the respective commitments to a body of stories and opens up a space for exchange and friendship between AI-researchers and theologians—an option that usually remains closed.     

Distanced Perspectives: Aids,Anencephaly, and Ahp

US court decisions guaranteeing life-sustaining care to anencephalic infants have been viewed with disfavor, and sometimes disbelief, by some ethicists who do not believe in the necessity of life-sustaining support for those without cognitive abilities or an independently sustainable future. The distance between these two views – one legal and inclusive, the other medical and specific – seems unbridgeable. This paper reports on a program using multicriterion decision making to define and describe persons in a way which both acknowledges the differences perceived by many as well as those commonalities insisted on in U.S. court decisions. It does this through application of the Analytic Hierarchy Process to a hierarchy of humanness criteria, and secondarily through reference to that concept's subset, personhood.     

Detection of color in rotating objects by infants and its generalization over changes in velocity.

In three experiments, infants between 8 and 20 weeks of age were familiarized during habituation trials to either a stationary or revolving patterned cylinder (Experiment 1) or to the same object when it was revolving at one of two angular velocities (Experiments 2 and 3). In the postfamiliarization trials, angular velocity was changed with the color of the pattern either the same as or different from that in the familiarization trials. The results showed that the infants were not only sensitive to movement and changes in velocity but to the color of the moving pattern. Furthermore, this response to color generalized across changes in angular velocity. These findings indicate that a necessary condition for identity constancy, detection of an object property with object transformations, is present between 8 and 20 weeks, prior to the stage of manual manipulation of objects. A number of subsidiary findings concerning movement discrimination at 55 and 100 cm viewing distances by 11- and 17-week-old infants are also described.
