The properties of retrieval cues constrain the picture superiority effect

In three experiments, we examined why pictures are remembered better than words on explicit memory tests like recall and recognition, whereas words produce more priming than pictures on some implicit tests, such as word-fragment and word-stem completion (e.g., completing -l-ph-nt or ele----- as elephant). One possibility is that pictures are always more accessible than words if subjects are given explicit retrieval instructions. An alternative possibility is that the properties of the retrieval cues themselves constrain the retrieval processes engaged; word fragments might induce data-driven (perceptually based) retrieval, which favors words regardless of the retrieval instructions. Experiment 1 demonstrated that words were remembered better than pictures on both the word-fragment and word-stem completion tasks under both implicit and explicit retrieval conditions. In Experiment 2, pictures were recalled better than words with semantically related extralist cues. In Experiment 3, when semantic cues were combined with word fragments, pictures and words were recalled equally well under explicit retrieval conditions, but words were superior to pictures under implicit instructions. Thus, the inherently data-limited properties of fragmented words limit their use in accessing conceptual codes. Overall, the results indicate that retrieval operations are largely determined by properties of the retrieval cues under both implicit and explicit retrieval conditions.     

A method for calibrating an eye-monitoring system for use with infants

An algorithm for calibrating data from an infrared corneal reflection eye movement monitor is described. The algorithm is designed for use with infants and other noninstructable subjects.     

Heteronyms and polyphones: Categories of words with multiple phonemic representations

Heteronyms are words that have two different possible pronunciations that are associated with two (or more) different meanings. They can be used to investigate psychological mechanisms in reading and other cognitive processes. A corpus of English heteronyms has been collected and is tabulated here. In addition, a corpus of English polyphones is tabulated. These are words with different pronunciations that are not associated with different meanings.     

Factor analysis of the wisc-r and the wrat with a referral population

Scores on the WISC-R and the WRAT from a referral sample of 250 children, ages 6 through 11, were factor analyzed using a principal factor method with varimax rotation. Results offered support for interpretation of WISC-R scores in terms of Verbal and Performance scales, and for interpretation of WRAT scores as a separate achievement factor. The contention that achievement and intelligence tests measure identical constructs is challenged.     

The relationship of selected consultant/teacher characteristics to consultation outcomes

This study examined the relationship of teacher life position, teacher dogmatism, perceived consultant facilitativeness, years of teacher teaching experience and number of consultations per year to the consultation outcomes of teacher satisfaction, teacher strength, and problem resolution. A number of significant findings resulted, with the consultant's perceived facilitativeness being the main predictor of the desirable consultation outcomes. These results are consistent with some earlier findings. Some results that are inconsistent with other studies also are discussed.     

Student perception of school environment and its relationship to mood,achievement, popularity,and adjustment

This study examined relationships between student perceptions of classroom environment and mood, achievement, popularity, and adjustment, both for students in general and for problem (i.e., acting-out, anxious, and unpopular) children. Subjects included 511 fifth- and sixth-grade students from 23 classes in four suburban schools. Class environment was assessed by responses to a short form of the Classroom Environment Scale (CES). Students also completed mood adjective checklists and peer sociometric ratings. Reading and arithmetic report card grades and achievement test scores were recorded for the school year, and teachers submitted adjustment ratings for all students. Classes, rather than students, were used as the main unit of analysis. For classes in general, high perceived Order and Organization and Affiliation related to greater student popularity. Relationships between perceptions of class environment and the dependent measures were stronger for problem students. For that group, high perceived Order and Organization, Affiliation, and Innovation related to positive mood, greater peer popularity, and teacher ratings indicating more positive adjustment. This study was supported by grants from the National Institute of Mental Health (MH 14574-04) and the New York State Department of Education. That support is acknowledged with gratitude as are specific contributions made by Evelyn Arlas, Ellis L. Gesten, and Elizabeth Kaplan.     

Human patellar reflex and conditioned reflex compared electromyographically

Inspite of continued work on the stretch reflex and “voluntary” movement study of the conditioned stretch reflex declined early in this century. The present experiments surveyed seven classical conditioning regimens for the human rectus femoris EMG seen after a blow to the patellar tendon. It was possible to (1) rule out conditioning to a knee touch that occured together with the tap, (2) establish weak conditioned stimulus, Sc, control for a tape recorder click and subsequent fist clench that preceded the tap by variable elapsed times, and (3) establish strong Sc control for a tone that sounded an invariant 0.27 sec before the tap. There were large differences, however, in Sc power across subjects, as measured by amplitude, latency, and frequency of conditioned EMG activity that occured prior to tap or when the tap was omitted. Purely reflexive responses, especially later EMG segments, also varied in amplitude and frequency, to support a conclusion that numerous controlling stimuli added or competed from trial to trial. Further disclosure of Sc contributions, including those from movement-generated stimulation, is warranted, especially for behaviors whose rhythmic timings, as in locomotion, might favor Pavlovian conditioning.     

Sex differences in the structure of intelligence: A confirmatory factor analysis

The LISREL model of Jöreskog and Sörbom was used to perform a comparative factor analysis on intelligence data from four sex by generation groups. The covariance matrices for 10 psychometric ability measures were used to isolate Spatial and Verbal Intelligence factors. Results from a series of factor analysis models indicated substantial invariance in the factor pattern and factor covariance matrices, although the hypothesis of complete invariance in factor pattern was rejected. The groups did differ in observed and unique variances. The results were basically consistent with the hypothesis that males and females have similar intellectual structure, which would have been obscured had standardized factor analysis been employed. There were also sex and generation differences in the Spatial and Verbal factor means.     

Noise stress and circadian arousal in self-paced computation

Previous work(Frankenhaeuser & Lundberg, 1977) has shown that unpaced mental arithmetic is performed at slower rates in noise, despite unchanged catecholamine indices of arousal; only male subjects were used, tested early in the day. Since the times of testing entail arousal effects that interact with noise stress, and the sex of subject further modifies these interactions, a new experiment was designed to include these variables. Men and women were tested on the Norinder mental arithmetic task, in quiet or in noise, either in the morning, when arousal was low, or during the early evening, when temperature curves indicate that arousal should be high. Analysis of the number of problems attempted shows a significant drop for men in noise in the morning, but an interaction due to reversal of the noise effect in the evening; there is no main effect of noise when women's scores are included. The results are compatible with interpretations combining motivation and cognition, and they demonstrate the importance of the experimental variables in explaining noise stress effects.The authors are indebted to the late David A. Shipp for his assistance in running subjects.     

Men's friendships,women's friendships and the alleged inferiority of the latter

Over a decade of research utilizing a model and technique for the study of same-sex friendships has revealed some unsought and initially unexpected differences between men and women. Relevant aspects of this research are reviewed. Taken as a whole, the findings indicate overall differences between men and women that were readily interpretable in terms of traditional sex roles and socialization practices. However, when differences were found, they were seldom extremely large or glaringly obvious and thus provide no sound basis for predicting the character of the friendship of any particular pair of men or women. Moreover, when the friendships examined were limited to those that were very strong and of long duration, no appreciable sex differences were found. Special attention is given to the contention that women's friendships are inferior to those of men.
