Another look at semantic priming without awareness

In a recent study, McCauley, Parmelee, Sperber, and Carr (1980) reported results indicating that semantic priming had been produced by visual stimuli that were backward masked at durations too brief for greater than chance report. The conclusions drawn from such an experiment are critically dependent upon whether or not the primes were actually masked below the thresh-old for identification during priming trials. The three experiments reported here provide evidence that this requirement was not met. Rather, McCauley et al.’s (1980) methodology allowed for an uncontrolled increase in light adaptation during the actual testing of prime efficacy in the priming session. This increase in light adaptation reduced the effectiveness of the backward mask and resulted in an increase in prime visibility during priming trials. Thus, semantic priming probably occurred under conditions in which commensurate visual information was actually available.     

Behavioral,psychological, and historical correlates of MacAndrew scale scores among male alcoholics

Male alcoholic veterans (N=194) were divided into four groups on the basis of their scores on the MacAndrew scale (MAC) of the Minnesota Multiphasic Personality Inventory (MMPI) and compared on psychological and sociodemographic measures and self-reported alcohol, drug, and legal histories. Nineteen subjects scored in the nonalcoholic (NA) range of the MAC (i.e., false negatives, MAC23). Remaining subjects, scoring in the alcoholic range of the MAC, were divided into thirds by MAC scores (lowest third, L-MAC=24–28,n=53; middle third, M-MAC=29–31,n=63; highest third, H-MAC>31,n=59). Groups did not differ on age, any important sociodemographic variables, or scores on the Profile of Mood States, State-Trait Anxiety Inventory, Symptom Checklist-90, or Rod and Frame Test. Significant group differences were obtained on several MMPI scales. Lower MAC scores were associated with higher scores onL, K, D, andR, and lower scores onMa. There was also a tendency for subjects with lower MAC scores to score higher onSi. NA subjects began drinking and heavy drinking later than other subjects, although groups did not differ on duration, quantity, or frequency of drinking. Subjects with higher MAC scores more often reported drinking in bars, drinking liquor straight, alcohol-related job disruptions, and previous use of marijuana, hallucinogens, and barbiturates. Subjects with higher MAC scores had more often been arrested, convicted, fined, and jailed for alcohol-related offenses but not for other offenses. Results are examined with respect to MacAndrew's distinction between primary and secondary alcoholics and with respect to the possible relations of MAC to important person variables such as sensation seeking.The authors wish to thank Craig MacAndrew for his helpful critical reading of an early draft of this paper.

Toward a functional theory of reduction transformations

The theory is advanced that reduction transformations function to provide speakers with the option of deleting redundant information when communicating to a topic-cognizant addressee and/or when using a written mode. To test the theory, an experiment was run in which subjects from an advanced cell physiology class were given a list of deep structure proximal sentences (base propositions), all pertaining to the topic of cellular energy, and were asked to communicate them, in either a written or oral mode, to either graduate students in biochemistry or freshman nonscience majors. An analysis of the subjects' use of reduction transformations when communicating the base propositions supported the redundancy-deletion theory developed in the paper. The implications of these results for the perceptual complexity theory of reduction transformations (Fodor & Garrett, 1967) are discussed.     

Socialist realism in the Soviet Union: Portrayal of Western European and North American businessmen

Success in Soviet trade negotiations depends to a great extent on the images that the Soviet negotiators form of their Western counterparts. These images, in turn, depend to a great extent on the images presented to such Soviet negotiators during their education, through various tales and stories.     

Experimental measures and theoretical account of hue scaling as a function of luminance

Functions relating the magnitude of chromatic response to stimulus luminance were determined at the unique green and yellow wavelengths. These measured functions were used to account for the shift from a preponderance of green at low stimulus luminances to a preponderance of yellow at higher luminances, for a stimulus wavelength of 550 nm. The two hue magnitude functions were found to have the same power-law exponents, and the hue shift was due to the difference in thresholds between the two opponent-color systems.     

Form recognition: Individual strategies in multivariate cue utilization

Twenty-five Ss were each presented 1,250 trials in a form-recognition task requiring S to find a form among 25 other forms on each trial. Fifty different eight-sided randomly derived polygons were used as stimuli, each presented in 25 different problems. Factors based on physical measures of the stimuli were correlated with observed latencies using multiple regression to assess cue-utilization strategies, while beta-weight profiles and intercorrelations of the Ss’ predicted latencies were used as indices of individual differences. Multiple correlations of physical-factor scores with observed latencies accounted for a significant proportion of the variance for all Ss, while between-S correlations of predicted latencies were never below .90. By all criteria employed, use of stimulus information was highly consistent among Ss. Replication of the experiment for one S revealed good reliability and nearly identical strategies.     

Differential Perceptions of College Environment: Student Personnel Staff and Students

The College Characteristics Index was administered to 160 randomly selected students, 15 head residents, and 20 members of the student personnel staff. Considerable disparity in perception of the environment was found among the 3 groups. Generally, students perceived the environment as possessing a greater degree of all the characteristics measured and valued by the academic community (i.e., aspiration level, intellectual climate, and academic achievement) than did the other reference groups. The differences in perceptions suggest that head residents and other student personnel staff may be involved with selected aspects of the campus life and with atypical groups of students.     

Student Patterns of Financing Education at a Land-Grant University

A financial aid survey was administered to the entire student body (10,185) at a land-grant university. The data showed that parental assistance was the main source of financial support, but that it declined in importance each year, while student employment by the university increased each year. Legislation providing increased opportunities for student employment appears to be appropriate and desirable. A wide variety of individual solutions to financial planning were noted.     

Parsing to Learn

Learning a language by parameter setting is almost certainly less onerous than composing a grammar from scratch. But recent computational modeling of how parameters are set has shown that it is not at all the simple mechanical process sometimes imagined. Sentences must be parsed to discover the properties that select between parameter values. But the sentences that drive learning cannot be parsed with the learner's current grammar. And there is not much point in parsing them with just one new grammar. They must apparently be parsed with all possible grammars, in order to find out which one is most successful at licensing the language. The research task is to reconcile this with the fact that the human sentence parsing mechanism, even in adults, has only very limited parallel parsing capacity. I have proposed that all possible grammars can be folded into one, if parameter values are fragments of sentential tree structures that the parser can make use of where necessary to assign a structure to an input sentence. However, the problem of capacity limitations remains. The combined grammar will afford multiple analyses for some sentences, too many to be computed on-line. I propose that the parser computes only one analysis per sentence but can detect ambiguity, and that the learner makes use of unambiguous input only. This provides secure information but relatively little of it, particularly at early stages of learning where few grammars have been excluded and ambiguity is rife. I consider three solutions: improving the parser's ability to extract unambiguous information from partially ambiguous sentences, assuming default parameter values to temporarily eliminate ambiguity, reconfiguring the parameters so that some are subordinate to others and do not present themselves to the learner until the others have been set. A more radical alternative is to give up the quest for error-free learning and permit parameters to be set without regard for whether the parser may have overlooked an alternative analysis of the sentence. If it can be assumed that the human parser keeps a running tally of the parameter values it has accessed, then the learner would do nothing other than parse sentences for comprehension, as adults do. The most useful parameter values would become more and more easily accessed; the noncontributors would drop out of the running. There would be no learning mechanism at all, over and above the parser. But how accurate this system would be remains to be established.
