Lateralization effects in the perception of Hebrew and English words

A series of four experiments was conducted on Israelis with a good knowledge of English, Anglo-Saxons with a good knowledge of Hebrew, and full Bilinguals of the two languages. In all experiments words were presented vertically and measurements of both accuracy and response times were taken. Experiments 1 and 2 examined the perception of Hebrew words in unilateral and bilateral conditions, respectively; Experiments 3 and 4 examined the perception of both Hebrew and English words in these two conditions. The results revealed right visual field advantage in the perception of words in both languages and in all groups. A reversal between the two conditions was not found. The data support the hypothesis whereby nonnative languages are less lateralized than native ones, but they indicate that full bilinguals are more, not less, lateralized than monolinguals. Various hypothesis regarding the relationship between lateralization and bilingualism are discussed.     

The child's fear of infanticide and the nuclear cause of the neuroses

The concept that the child is predisposed to the fear of infanticide, and that that fear may be the central cause of his psychological problems and the primary motive force of his defense, allows us to view the defensive process from a different perspective than that offered by Freud's nuclear theory. Children's fantasies make it apparent that the idealization of their parents' image, and the devaluation of their own, constitute their basic defense against their fear.     

Cognitive psychology and modern physics: Some analogies

Abstract

Patterns in physics and psychology are often related. This paper examines such relations on two levels. First, a survey is made of the various possible relations between physics and psychology and, secondly, a series of analogies between patterns in modern physics and cognition is presented. The analogies pertain both to the theory of relativity (both special and general) and to quantum mechanics. While the different analogies noted are argued for independently from one another, together they do present some unified patterns. It is argued that the analogies may be useful in opening up avenues for new conceptual bameworks in psychology. In particular, they are linked to a possible critique of the representational view of mind.     

Thought sequences

Abstract

Thought sequences are ordered series of verbal-like expressions that pass spontaneously through one's mind and which are characterised by well-demarcated beginnings and ends. The present paper notes the significance of and interest in thought sequences and presents a framework for their analysis. Given the scope of the enterprise, different levels of analysis are noted which set the boundaries for the present investigation, and define guidelines for further research. Here, the focus of interest is the structural (as distinct from either functional or computational) relationships between pairs of consecutive expressions. The informational bases for these relationships are reviewed and a typology of them is drawn. The typology reveals marked internal structure and it suggests that the variety of couplings of thought sequences constitutes a space spanned by a small number of variables. Methodological issues regarding the use of introspection in cognitive research are also discussed.     

Ocular motility and visuo-spatial attention in children with periventricular leukomalacia

Periventricular leukomalacia (PVL) is known to cause visual, motor, and cognitive impairments varying in their severity. Most studies focused on impairment at early ages. Little is known about the PVL's later outcome. Effects of neural plasticity are for instance insufficiently known to prognose precisely their behavioral outcome. It is even hard to determine the consequence of one defect on global development over time. Because of the established neural link between eye motion and space perception, 5-to-9 year-old PVL's were tested in visual detection, postural control, and space attention tasks. In this paper, discussion will focus on behavioral asymmetry, developmental outcome, and brain injury.     

Yesterday,today and tomorrow

1260 American subjects were timed as they responded to one of the three questions (‘What day of the week is today?’ (Tod question), ‘What day of the week was yesterday?’ (Y question), and ‘What day of the week will tomorrow be?’ (Tom question)) at one of three times of the day (early morning, mid-day and the late evening). Response times as a function of the day on which the question was posed defined an inverted U-curve for all questions in all three conditions. The Tod question always triggered the fastest responses. In the morning, responses to the Y question were faster than responses to the Tom questions, whereas in the evening the converse was the case. At mid-day responses to the Y question were faster than responses to the Tom question at the beginning of the week and slower than those at its end. The patterns of introspection associated with the responses also defined reversed U-functions. The results are interpreted in the framework of a multi-channel spreading activation model.     

Lateralization effects in lexical decision tasks

Subjects were timed as they judged whether items presented to them were English words or not. Comparisons were made between responses to nouns and to verbs, on the one hand, and between concrete and abstract nouns, on the other hand. No asymmetries were found.
