Graphemic analysis underlying literacy

Three experiments are described that studied the role of detailed graphemic analysis upon the ability to read text. College students named letters in various approximations to English, with frequency of individual letters constant. Findings were that later skill at reading varied with the order of approximation to English of the letters that were named, that the spacing of the letter sequences was important to this result, and, finally, that the influence of specific visual practice extended to the typeface on which the naming and reading were carried out. Hence, rather than a letter-by-letter process or its opposite, a wholly semantic analysis, reading is shown to be intimately dependent upon details of visual analysis of patterns or letter sequences.     

Knowing not

Ontario Institute for Studies in Education, 252 Bloor Street, Toronto, Ontario, Canada M5S 1V6 People often know rapidly and reliably that they do not know something. A review of contemporary theory reveals that the issue has not received much attention; moreover, the accounts available assume that recognition that one does not know something is achieved only by failure to establish that one does know it. A reaction time experiment assessed two aspects of knowing not, by asking people whether they knew common nouns well enough to use them in sentences and whether they had visited certain cities. The findings were that affirmations of negation were often more rapid than positive reports; hence, the account of knowing not as the complement of knowing that something is the case is not necessarily correct. We suggest that knowing not may be attained as rapidly as positive knowledge on the basis of ability to carry out analytical procedures.     

Judging pictorial and linguistic aspects of space

A test is made of the notion that Stroop-like interference and facilitation effects arise from two different sources, one pictorial and the other linguistic. It was hypothesized that when irrelevant information is pictorial, it interferes with a pictorial code used in the processing of the relevant information; when it is linguistic, it interferes with a linguistic code. The experiment required subjects to respond to (1) the meaning of a spatial word, t2) its absolute position, or (3) its relative position, while attempting to ignore the two irrelevant dimensions of the display. It was found that word meaning and absolute position information affected the speed of relative position judgments in an additive manner. No other Stroop-like effects were found. The results supported the hypothesis under test. It was concluded that the existence of different kinds of Stroop effect must be accommodated by current models of the phenomenon.     

Culture in the context of intercultural negotiation.

This study explores culture's effect on behaviors and outcomes in intercultural negotiation and examines how those effects are moderated by role. Eighty U.S. and international students took part in a previously developed negotiation task (Pruitt, 1981) and completed Hui and Triandis's (1986) individualism‐collectivism (INDCOL) scale. Negotiation interactions were coded for information sharing, offers, and distributive tactics. Findings show that a negotiation dyad's collectivism is positively associated with higher joint profit. The effects of culture on both communication behaviors and joint outcomes, however, differ by role of the negotiator. In particular, seller collectivism has larger and more consistent effects on communication behavior and joint profit than buyer collectivism. Results support a ‘culture in context’ perspective of negotiation that takes into account negotiator qualities, contextual and structural features of the negotiation, and mediating processes in addition to cultural values.     

THE CONTROL OF BIAS IN RATINGS: A THEORY OF RATING

Based on several years of research and a careful analysis of the rating process Wherry developed a theory of rating. An accurate rating is seen as being a function of three major components: Performance of the ratee, observation of that performance by the rater, and the recall of those observations by the rater. Cast in a mold of classical psychometric theory each of these components is seen as consisting of a systematic portion and a random portion. The systematic portion of each component is further broken down. The performance of the ratee is a combination of true ability or aptitude for the job and the influence of the environment. What the rater observes is a function the performance of the ratee and bias of observation and what the rater recalls is a result of those observations combined with a bias of recall. The development of the theory of rating unfolds by defining the various factors that affect each of these components in a series of linear equations. Various theorems and corollaries are proposed which should lead to a maximization of the true ability component of the ratee and minimize environmental influence and the bias and error components. The theorems and corollaries suggest testable hypotheses for the researcher in performance evaluation.     

Some stages of information processing in a choice reaction-time task

Eight pigeons were tested for head nystagmus in a rotating drum with vertical black and white bars on the reside. When the birds viewed monocularly, they gave about four times as many responses to nasalward as to temporalward movement. However, no such asymmetry was observed in a discrimination paradigm. Six pigeons were taught binocularly to discriminate moving lines, which moved equally often to left and fight, from stationary fines. They were then tested monoculaxly, and the discrimination was controlled about equally by nasalward and temporalward movement.
