Reaction times and speed-of-processing: Their relationship to timed and untimed measures of intelligence

Eighty-one university students were given a battery of reaction time tests, measuring the speed with which they performed various elementary cognitive processes, and a group test of intelligence which yielded timed and untimed scores. Multiple regression analyses indicated that speed of information-processing was an equally good predictor of timed and untimed intelligence test performance, and that various combinations of speed-of-processing variables accounted for as much as 48% of the variance in intelligence test scores. Different speed-of-processing variables varied relatively systematically in the extent to which they correlated with the individual subtests and scales of the intelligence test.     

Differential cerebral involvement in perceiving Chinese characters: levels of processing approach

Three experiments were designed to determine the accuracy and latency with which right-handed Chinese university students (12 females and 12 males) recognized Chinese characters in the left and right visual half-fields (VHFs). The experiments varied in the "depth" of processing required. Experiment 1 was a lexical decision task in which the configuration of the stimulus (a real Chinese character or the mirror image of a real character) determined whether the grapheme was an actual character. Experiment 2 required phonological processing; i.e., subjects had to decide whether a character (or a foil) matched the sound of an orally presented Chinese character. Experiment 3 required semantic processing; i.e., subjects had to decide if a character (or a foil) belonged to a particular semantic category. In each experiment, single characters were presented unilaterally for 150 msec. There was a significant right VHF superiority for accuracy scores for Experiments 2 and 3 but not for Experiment 1. None of the experiments yielded significant visual asymmetries in reaction time. The results do not support previous claims of orthography-specific laterality, but instead show that laterality effects for morphemic stimuli vary with the orthographic, phonological, and semantic processing demands of the task.     

Piaget's Grouping II: The model, its assessment, and the effects of training

Although Piaget emphasized the importance of negation in equilibration theory, few data are available pertaining to children's use of Grouping II (Gr. II) logic, which relies on negation. Three approaches to assessing Gr. II capability are reviewed in light of Piaget's (1949, Traité de logique: Essai de logistique opératoire, Paris: Colin) discussion of Gr. II. The paper describes a new task to assess three aspects of Gr. II thought: (a) naming secondary classes, (b) comparing a secondary class with a primary class contained within it, and (c) reasoning about vicariance relationships. An experimental group of third graders trained to use Gr. II logic performed significantly better on post-test tasks than did an untrained control group. Training included rule instruction, evaluative and informative feedback, and manipulative activities.     

Opposite ERP effects for conscious and unconscious semantic processing under continuous flash suppression

We examined whether semantic processing occurs without awareness using continuous flash suppression (CFS). In two priming tasks, participants were required to judge whether a target was a word or a non-word, and to report whether the masked prime was visible. Experiment 1 manipulated the lexical congruency between the prime-target pairs and Experiment 2 manipulated their semantic relatedness. Despite the absence of behavioral priming effects (Experiment 1), the ERP results revealed that an N4 component was sensitive to the prime-target lexical congruency (Experiment 1) and semantic relatedness (Experiment 2) when the prime was rendered invisible under CFS. However, these results were reversed with respect to those that emerged when the stimuli were perceived consciously. Our findings suggest that some form of lexical and semantic processing can occur during CFS-induced unawareness, but are associated with different electrophysiological outcomes.     

An ERP study of sensory mismatch expressions in Japanese

Combinations of different sensory words produce mismatch expressions like smooth color and red touch in contrast to normal expressions like red color and smooth touch. Concerning these sensory mismatch expressions, results of three experiments are reported. Experiment 1 revealed that (i) mismatch expressions were less comprehensible than normal expressions, and that (ii) there were two patterns among mismatch expressions: the high-comprehensible mismatch expression (HighCME, e.g., smooth color) and the low-comprehensible mismatch expression (LowCME, e.g., red touch). Experiment 2 revealed that the mismatch expressions produced a significantly greater N400 amplitude than the normal expressions. Experiment 3 implied that the difference between High/LowCME was reflected in a later latency band or in a topographical difference of N400, although the statistical significance was marginal. It is argued that the processes to integrate linguistic elements (e.g., combining adjectives and nouns) are not homogeneous.     

Martin Heidegger and Russian Symbolist Philosophy

In this paper Russian Symbolist philosophy is represented primarily by Viacheslav Ivanov (1866--1949), but its conclusions are intended to be valid for other philosophers we classify as Symbolist, including Nikolai Berdiaev and S. L. Frank. It is posited that, by comparing Ivanov's cosmology, aesthetics, and anthropology to those of Martin Heidegger, one can reconceive of Symbolist philosophy as an existential hermeneutic. This, it is claimed, can help to identify a common basis among the Symbolist philosophers, and also to place Russian thought in the context of modern European philosophy and vice versa.     

Neuropsychological analysis of a case of crossed dysphasia verified at postmortem

A case is reported of crossed dysphasia in a right-handed monolingual patient, where neuropathological verification of the unilateral site of the lesion was obtained within a year of detailed neuropsychological assessment. The patient's pattern of language impairment was characterized by agrammatic speech and relatively preserved naming ability. In addition, the patient had good repetition, poor comprehension, and marked impairment on visuospatial tasks. Neuropathological investigations showed a large area of infarction affecting cortex, white matter, and subcortical structures in the right hemisphere. The possibility is discussed of a distinction between two types of crossed dysphasia with either dissociated or simultaneous language and visuospatial deficits due to reversed representation of hemispheric specific functions or transfer of most cognitive functions to the right hemisphere.     

Speeded recognition of ungrammaticality: Double violations

A model of sentence comprehension postulating that Subject-Verb-Object relations are specified prior to Noun-Adjective relations received support from a study of the speed at which sentences with various kinds of violations could be rejected. Compatible with the sequential model was the finding that Noun-Verb and Adjective-Noun double violations did not result in shorter RTs than Noun-Verb single violations — even though sentences with double violations were judged to be less acceptable.     

Vocational behavior and career development, 1978: A review

In sum, the research in 1978 was diverse and of good quality and quantity. However, there continues to be a clear need for longitudinal research of all kinds (in particular on the career development process) and a need for additional research with the employed adult population, although the past few years demonstrate improvement in the latter area.In 1978 the most productive research area as suggested by this review was associated with the women's movement and manifested by research primarily on sex stereotyping and women's careers. Ranking second was the topic of theoretical developments in vocational behavior led by the research on Holland's constructs. These two research trends accounted for about 50 studies; 26 and 24, respectively. Job satisfaction assumed the third position with some concentration on satisfaction and work motivation. Next and very much clustered were life-span aspects, assessment, and job performance. Each of these research themes stimulated about 17 studies that were reviewed here. Vocational interventions and race differences received moderate attention while job interview variables and occupational environments sparked very limited work in the more psychologically oriented journals.The major contributor to the 1978 review was of course the Journal of Vocational Behavior (62 studies), followed by the Journal of Applied Psychology (25 studies). Five other journals contributed an average of about 10 studies. These were the Journal of Counseling Psychology, Journal of Measurement and Evaluation in Guidance, the Journal of Organizational Behavior and Human Performance, Personnel Psychology, and the Vocational Guidance Quarterly. These appear to be the major journals publishing work on vocational behavior and career development.Finally, the volume of research on vocational psychology continued on an upward trend in 1978. This review and the previous reviews (Betz, 1977; Osipow, 1976; Zytowski, 1978) clearly document this trend.
