Navigating through abstract decision spaces: Evaluating the role of state generalization in a dynamic decision-making task

Research on dynamic decision-making tasks, in which the payoffs associated with each choice vary with participants’ recent choice history, shows that humans have difficulty making long-term optimal choices in the presence of attractive immediate rewards. However, a number of recent studies have shown that simple cues providing information about the underlying state of the task environment may facilitate optimal responding. In this study, we examined the mechanism by which this state knowledge influences choice behavior. We examined the possibility that participants use state information in conjunction with changing payoffs to extrapolate payoffs in future states. We found support for this hypothesis in an experiment in which generalizations based on this state information worked to the benefit or detriment of task performance, depending on the task’s payoff structure.     

The encounter with God in myth and madness

Background

It is well known how often psychiatric patients report religious experiences. These are especially frequent in schizophrenic and epileptic patients as the subject of their delusions. The question we pose is: are there differences between this kind of religious experiences and those we find in religious texts or in the mythological tradition?

Results

An overview on famous mythological narratives, such as The Aeneid, allows us to establish that the divinities become recognizable to the human being at the moment of their departure. Thus, Aeneas does not recognise his mother, Venus, when she appears to him in the middle of the forest at the coast of Africa. A dialogue between the two takes place, and only at the end of the encounter, when she is going away and already with her back to Aeneas, she shows her son the signs of her divinity: the rose-flush emanating from her neck, her hair perfume and the majesty of her gait. Something analogous can be observed in the encounter of Moses with Yahweh on Mount Sinai. Moses asks God: "Show me your glory, I beg you". And God replies, among other things: "you shall see the back of me, but my face is not to be seen". In the same sense, the Emmaus disciples do not recognise Jesus till the moment of his disappearance ("but he had vanished from their sight"), and Saul of Tars falls off his horse just in the moment when he feels the divine presence. In short, the direct encounter with the divinity seems not to occur in the realm of myth or in religious tradition. The realm of madness is exactly the opposite. Our research on religious experiences in schizophrenic and epileptic patients leads us to conclude that God appears to them face to face, and the patient describes God the father, Jesus or the Virgin Mary in intimate detail, always in an everyday setting. So, the divinity is seen in the garden, or in the bedroom, or maybe above the wardrobe, without any of its majesty. The nearness to God also tends to be so extreme that even an identification of patient and God can occur. That light emanating from the world of the divine ceases to be perceived by them.

Conclusion

While in mythological narratives God appears to the human being at the moment of His departure or showing His back, psychiatric patients with religious delusions experience the divinity in a direct way, face to face. Given the deformation of the divine occurring on the edge of madness we can better understand the mysterious words from Yahweh to Moses in Exodus: "for man cannot see me and live".     

Memory deficits in young schizophrenics with normal general intellectual function

The aim of the present study was to examine different dimensions of memory functioning in young schizophrenics with normal general intellectual abilities. Thirty-three patients with schizophrenia and 33 healthy controls were included in the study. The results suggest that immediate short-term memory is intact, though there emerged a working memory deficit in the schizophrenia group. Deficient encoding of verbal material was observed in some, but not in other, testing conditions. There also seemed to be a retrieval deficit for verbal material in schizophrenia, though no storage deficit was indicated. Impaired memory for non-verbal material was also revealed. These results occurred in a context of intact executive functioning as measured by the Wisconsin Card Sorting Test. The results indicate that temporal and frontal structures, as well as their interconnections, may be compromised in schizophrenia.     

Abuse History, World Assumptions, and Religious Problem Solving

At a Christian university, 167 subjects completed questionnaires measuring worldview assumptions, religious problem solving, physical and emotional abuse, and subjects' beliefs about whether they had been "abused." Results indicated that worldview assumptions were not related to actual abuse histories. Instead, such assumptions were related to the subjects' beliefs that they had been abused. Subjects who believed that they had been abused had more negative views of the impersonal world, people, and themselves; they were also more likely to see events as random. Both actual abuse history and subjects' beliefs that they had been abused were related to religious problem-solving styles. Finally, problem-solving styles were related to various worldview assumptions. Results are discussed in terms of previous research on abuse and in the psychology of religion.

An empirical evaluation of a scale to measure occupational aspiration level

Data from 34,118 American high school students are used to evaluate the Occupational Aspiration Scale (OAS). The OAS is successively reevaluated for each of 16 subsamples (cells) generated by cross-classifying respondents by grade in school (9–12), sex, and socioeconomic status (SES). In each cell the OAS is found to be essentially unifactorial, and that factor is identified as level of occupational aspiration (LOA). The reliability of the OAS is slightly lower among females ($\text{r}$_kk = .681) than among males ($\text{r}$_kk = .756); it does not vary appreciably by grade or SES. The mean scores are lower for youth from low SES families than for those from high SES families, in accord with previous research. Mean OAS differences due to sex and grade are small. No important differences by age, sex, or SES are found in the standard deviations of the test scores. This and previously published data from small, local samples indicate that the reliability and validity of the OAS are sufficient for research on high school youth of both sexes and from both higher and lower SES levels.     

Understanding quantified categorical expressions

A model of categorical inference (Revlis, 1975b) claims that a conversion operation participates in the encoding of quantified, categorical expressions. As a consequence, a reasoner is said to interpret such sentences as “All A are B” in a way that permits it to also be the case that “All B are A.” The present study examines this conception of encoding using a sentence-picture verification task. In two experiments, students were asked to judge whether one of five possible Euler diagrams was true or false of a categorical expression (e.g., All A are B, No A are B, Some A are B, Some A are not B). Verification errors support a three-stage verification model whose major component is access to a “meaning stack” representing the progressive analysis of categorical relations; at the top of that stack is a converted reading of the input sentence. These findings have implications for current conceptions of categorical inference and semantic retrieval.     

AFFILIATIVE ASSOCIATIONS

The International Platform of the International Journal of Psychology plans a series of articles on the associations affiliated to the IUPS. The first article on the World Federation for Mental Health was written by a long time member of the Executive Committee of the IUPS, Professor Otto Klineberg, President of the World Federation for Mental Health.
