The development of automatic word recognition and reading skill

The development of automatic word recognition as a function of reading skill was investigated in three experiments using the Stroop task. Reading skill level ranged from nonreaders to readers above the sixth-grade equivalent. Interference with color naming begins to emerge early in the process of learning to read, increases, and then subsequently decreases. Strings of identical letters delayed color naming for children just beginning to learn to read. The interference from words, presumably reflecting semantic processing, began developing early but did not peak until the second- to fourth-grade reading levels. These different sequences of development of interference in the various stimulus conditions suggest that word recognition is the result of a number of component processes that develop as children acquire skill in reading.     

The identification of names in maternal speech to infants

Mothers' speech to 14-month-old infants was recorded during a free-play session. The findings suggest that this speech contained a number of characteristics which could facilitate the identification of names from the other words in an utterance; names were frequently the loudest word of an utterance and were highly likely to be positioned at the end of utterances. Thus, infants appear to receive a verbal input which may help them to identify semantically important words.This research was supported by an S.S.R.C. grant to H. R.

Contemporary Worldviews: Personal and Policy Implications12

In the past several decades, changes in industrial societies have presented a host of issues, worldwide in scope, around which individual attitudes may form: technological growth, population expansion, environmental quality, global resources, differing societal goals, etc. This study (N= 325) was conducted to identify and assess the major attitude/belief constellations surrounding these issues and to examine their psychological basis and implications for risk perception and societal decision-making procedures. Results supported the hypotheses that assessed contemporary worldviews are related in predictable ways to (a) the pexceived risk associated with selected technologies, (b) preferences for the manner in which societal decisions should be made, and (c) a coherent set of psychological variables. Discussion focuses on policy implications of differing contemporary worldviews and on future directions and applications of this line of research.     

“Impossible figures” and interpretations of polyhedral figures

The concept “impossible figure” is analyzed by formalizing the interpretations of a polyhedral figure by an observer, and defining several types of inconsistency in such interpretations. Tests for these inconsistencies are developed using simple graph theory, and a sufficient condition is established for the feasibility of an interpretation. Finally, techniques are derived for the automatic construction of usual or unusual multibar figures.     

Implicit psychophysiology: Effects of common beliefs and idiosyncratic physiological responses symptom reporting

Every individual exhibits unique perceptual, behavioral, and physiological responses within and across a variety of settings. Despite the idiosyncratic nature of responses, we seek to establish theories that generalize across a large number of individuals. A strict idiographic method intensively examines the response patterns of a small number of individuals, whereas a nomothetic approach focuses on common responses across a large number of individuals. In the present investigation, we seek to learn how individuals perceive and report physical symptoms and sensations. We offer a methodology that capitalizes on the unique physiological responses of individuals but, at the same time, assumes that the underlying perceptual processes relevant to symptom reporting are comparable across individuals. Our approach, then, is both idiographic and nomothetic. As will be discussed, this integrative approach has the potential to be applied to a multitude of behaviors and processes that are of interest to social and personality psychologists.     

The effects of reward on tutor's behaviors in a cross-age tutoring context

Utilizing a cross-age tutoring context, this study examined the effects of reward on the teaching behaviors of the tutor, the tutor's subsequent motivation to continue to teach during a free choice period, and the social interaction between a tutor and a tutee. Third-grade boys and girls (n = 96) who exhibited a positive reinforcement style were asked to teach six addition problems to a first-grade boy or girl (n = 96). The children were randomly assigned to pairs and to one of the three reward conditions. In the performance-contingent reward condition, the tutors were promised a toy if the first-grader learned all of the arithmetic problems. In the noncontingent reward condition, the tutors were promised a toy for teaching the first-grader. In the no reward condition, the tutors taught the first-grader without promise of a toy. The results indicated that the social interaction was rated lower for the children in the performance-contingent group and that the tutors in this group spent less time teaching during the free choice period. However, neither the tutor's teaching style nor the tutee's post-test performance was adversely affected by the reward.     

A voice-operated method for administering the MMPI

Paper/pencil psychological tests such as the Minnesota Multiphasic Personality Inventory (MMPI) are difficult to complete independently by patients with limited hand function. This paper describes a voice recognition system developed to allow patients with no hand function to take the MMPI independently. Profiles generated by this system are not statistically different from those generated by standard MMPI booklet format. Limitations and possible extensions of the system as it currently exists are discussed.     

Marijuana-induced primary process content in the TAT

Seventy-two normal adult male subjects wrote TAT stories under baseline and either placebo- or marijuana-ingestion conditions. Marijuana subjects received 20 mg. doses of delta-9 tetrahydrocannabinol. The stories were keypunched and content analyzed with the Regressive Imagery Dictionary, which yields a score for primary process content. Results indicate that marijuana, relative to placebo, caused subjects to write stories with a higher proportion of primary process content than they had included in baseline stories.     

The "consistency" controversy and the accuracy of personality judgments

Areas of clear and acknowledged disagreement in the personality literature's “consistency controversy” are surprisingly difficult to pin down. The present essay suggests that one basic and real disagreement nowadays is the admissability of subjective judgments of personality as data: Personologists are willing to use them, and situationists are not. Situationists generally regard judgments as so influenced by error as to be essentially unusable, and instead prefer direct measurements of specific behaviors. The relative uses and limitations of global judgments and specific measures are considered. It is concluded that any position that judgments reflect “nothing but” error is untenable. It is further concluded that each sort of data has distinct uses and limitations, provides a check on the other, and is indispensable.
