Observing behavior in monkeys (Macaca arctoides): Support for the information hypothesis

A single lever, discrete-trials observing procedure was used with stumptailed monkeys (Macaca arctoides). Lever-presses during a trial produced colored key lights (IS⁺ and IS^?) which signaled whether the trial would end with response-independent food or without food. During the baseline period, both IS⁺ and IS^? were produced on a variable-interval (VI) 15-sec schedule which began operating at the onset of the trial. The two experimental conditions involved a combination of this VI schedule and a DRL schedule. In one of these conditions, only a response that both met the VI requirement and was preceded by at least 6 sec of nonresponding could produce IS^? on nonfood trials, while the schedule for IS⁺ on food trials remained VI 15 sec. In the other experimental condition, the schedules for producing the two stimuli were the reverse. All subjects eventually learned to produce either IS⁺ or IS^? on the combined VI-DRL schedule. These data support an information hypothesis of observing in monkeys and contrast with data from pigeons which support a conditioned reinforcement hypothesis.     

On Some Affinities of Morin’s Complex Thinking with That of Chinese Classic Philosophy

Morin (1921) founded the complex mode of thinking in order to remedy the defects of the Western classic simple mode of thinking. In doing so, he approached to some degree the mode of thinking inherent to the Eastern civilization. This article elucidates that for some principles of Morin's complex thinking, such as correlation of opposites, recursive causality, and union of unity of multiplicity, there were similar ideas in Chinese classic philosophy. This shows that the complex paradigm of thinking, in a certain point of view, will be the fusion of Western and Eastern cultural factors. Besides, in integrating his theory of complexity with the reality of our time to find out solutions to the issues of globalization, Morin has become one of the representative thinkers of the planetary age of humankind.     

The vocational side of a new start in life: A career model of immigrants

The research tests a career model of immigrants with the following stages: crystallization, vocational retraining, job entry and trial, establishment, and maintenance. Two samples of immigrants, one consisting of 89 newcomers and another consisting of 60 white-collar workers with an average seniority of 5 years in the country, are followed up during a period of 2 years, after initially taking a test battery measuring vocationally relevant traits. Dependent criterion variables are occupational government examinations and adjustment to the job. Smallest space analysis is used to construct the career space of the newcomer cohort, and multiple regression of criterion variables on success predictors was performed. Both methods confirmed the model. The need arose to reconsider the duration of career stages of immigrants and their link to certain ages in comparison to the models in use. The research brought into focus the continuity of the process of career reconstruction after the interruption of vocational activity caused by emigration.     

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.     

Repetition in the transcortical aphasias

Transcortical aphasic patients were assessed on a repetition task comprised of both well-formed and deviant sentences. The patients faithfully repeated those sentences that were factually incorrect but grammatically well formed, and those sentences that were ungrammatical because of selection restriction violations. In contrast, presented with sentences featuring only minor syntactic violations (e.g., lack of number agreement), the patients spontaneously, and without awareness, resisted exact repetition; moreover, the resultant changes most often served to correct the syntactic deviations. Repetitions of sentences of this latter type also revealed a difference between the patients as a function of level of comprehension. The transcortical motor aphasic patient was influenced by semantic factors in his alterations of the minor syntactic violations, while the transcortical sensory aphasic was not. These findings are discussed in relation to the notion of autonomous syntactic processing. They are taken to suggest that syntactic facts such as number agreement are represented at a level in the processing chain that is distinct from that of semantic representation.     

Commitment to work in immigrants: Its functions and peculiarities

It was assumed that in order to cope with the crisis of immigration, immigrants would have low expectations regarding their vocational future while maintaining a high commitment to work. The meaningfulness and the centrality of work (as components of the commitment to work), work values, and work attitudes were tested in samples of 74 immigrants, of 66 old-time white-collar employees, and of 35 ongoing executives, by means of the semantic differential technique and by a projective personality test. An adaption of Eysenck's neuroticism test was also administered. Immigrants evaluated career and work-related objects in a less positive manner in comparison with the other samples, but scored higher in work centrality and job involvement, and held more positive attitudes toward authority figures in the place of work. No significant differences in neuroticism were found.
