The role of familiar units in perception of words and nonwords

This paper investigates the effects of familiarity with whole-word units and letter-cluster units in perceptual encoding of letter strings. Subjects viewed brief, masked presentations of words and pronounceable pseudowords differing in letter cluster frequency. Identification of both display types was compared to control single letters. Perceptual accuracy was indexed by probe forced-choice responses and full verbal reports of the displays. Evidence that familiarity of whole-word units facilitated encoding was mixed but, on balance, favorable. Evidence that familiarity of letter-cluster units facilitated encoding was completely absent. This negative finding is surprising in view of the fact that we did obtain a large advantage of letters in pseudo-words as well as words over single letters. The discussion section considers an alternative to the view that perceivers use detectors for familiar letter-cluster units in the process of forming representations of pronounceable, orthographically regular letter strings.     

In defense of intraperceptual theories of attention

A distinction is drawn between intraperceptual and extraperceptual theories of attention. Only the former class allows for the selective modulation of amount of nonconscious, perceptual processing of concurrent stimuli. The adequacy of intraperceptual theory has been questioned on the basis of diverse empirical findings. This literature is critically examined and is considered inconclusive partly because of the lack of an appropriate measure of amount of perceptual processing. A new experiment that attempts to provide such a measure is reported. Subjects detected names of states of the United States in dichotically presented lists. Subjects either could focus on just one list (relevant list) or had to divide their attention between the two lists. Amount of perceptual processing of a word (e.g., voice or titre) was measured in terms of the extent to which it primed subjects' interpretations of a visually presented homograph (e.g., spoke). Priming potency of words was greatest in the relevant list and was least in the other list. The data support a broad version of intaperceptual theory that allows for birth perceptual facilitation of relevant stimuli and perceptual suppression of irrelevant stimuli.     

Social motives among Anglo American and Mexican American children: Experimental and projective measures

The measurement approaches to social motives, cooperation-competition games and projective tests, have revealed apparently similar findings: Anglo American children are more competitive and higher in n Achievement compared to Mexican American children, who are more cooperative and higher in n Affiliation. The present experiment tested the extent to which (1) competitiveness is related to n Achievement, (2) cooperativeness is related to n Affiliation, and (3) the cultural differences in cooperation-competition are related to those in n Affiliation and n Achievement. Results indicate that social motives inferred from a cooperation-competition game have a meaningful relation to those inferred from a projective test, but that the cultural differences in cooperation-competition are larger and are not explained by cultural differences in n Affiliation and n Achievement. Social motives inferred from each measurement methodology, while somewhat related, are distinct.     

Confounding effects of individualism in children's cooperation — Competition social motive measures

The exact nature of cooperation — competition differences among children has remained obscure because the effect of individualistic motivation has important but unanalyzed influence on the frequency of cooperative and competitive responding. In order to clarify the nature of cultural differences in cooperation — competition, a novel social motive game was developed that provides distinct cooperative, competitive, and individualist alternatives. The measure was administered to 120 fourth-through sixth-grade Anglo-American and Mexican-American children of lower- and upper-middle-income levels. Consistent with previous research, Mexican-American children were generally more cooperative than Anglo-American children. Contrary to previous conclusions, however, individualism, not competition, was the strongest social motive among children, and Anglo-American children were generally more individualistic but not generally more competitive than Mexican-American children. Culture findings challenge both the methods and the results of previous cooperation — competition studies.The present research was partially supported by a University of California Intramural Research Grant No. 5-538404-19900-5.

Issues in replicating the Trauma—Stren conversion

The Trauma--Stren (T-S) conversion procedure was examined at a large state university and the construct related to personality and cognitive process variables. Significantly more respondents reported T-S conversion than in the original studies. Conversion was not significantly correlated with personal variables. The presence of experiences in which an event was reported as simultaneously traumatic and strenful is reported, and the criteria for clearly identifying the conversion phenomenon are questioned.     

Can practice eliminate the psychological refractory period effect?

Can people learn to perform two tasks at the same time without interference? To answer this question, the authors trained 6 participants for 36 sessions in a Psychological Refractory Period (PRP) experiment, where Task 1 required a speeded vocal response to an auditory stimulus and Task 2 required a speeded manual response to a visual stimulus. The large PRP effect found initially (353 ms in Session 1) shrank to only about 40 ms over the course of practice, disappearing entirely for 1 of the 6 participants. This reduction in the PRP effect with practice is considerably larger than has been previously reported. The obtained pattern of factor interactions between stimulus onset asynchrony and each of three task difficulty manipulations (Task 1 judgment difficulty, Task 2 stimulus contrast, and Task 2 mapping compatibility) supports a postponement (bottleneck) account of dual-task interference, both before and after practice.     

Religiousness,Religious Orientation,and Attitudes Towards Gays and Lesbians1

Two studies are reported that examine the relationships among religiousness, religious orientation, and prejudice toward gays and lesbians. Study 1 reports the results of a survey done for the purposes of scientific jury selection. These results suggest that Baptists, fundamentalists, and “Christians” display more antigay prejudice than do Catholics, Jews, and many Protestant denominations, but even many supporters of gay-tolerant religions show more antigay prejudice than those claiming no religious preference. Among those with a religious preference, frequency of worship is significantly related to antigay prejudice among those belonging to antigay denominations, but not among those belonging to more gay tolerant religious faiths. Study 2 reports the results of a study of college students regarding religiousness, religious orientation, and prejudice toward gays and lesbians. Results showed that self reported religiousness, frequency of worship, and Batson's internal and external scales were all positively correlated with measures of prejudice toward gays and lesbians, whereas scores on the Quest (Interactional) scale were negatively correlated. Results of both studies strongly challenge the view that those with an intrinsic religious orientation are unprejudiced. It is argued that a social influence process can account for the role played by religious practice and beliefs in creating and maintaining negative attitudes toward gays and lesbians.
