Ear differences in simple reaction time: The influence of attentional factors

Simple motor reaction times (right-handed) to tape-recorded consonant-vowel syllables were obtained from 12 subjects under two conditions of monotic stimulation: “expected” presentation (subject informed as to ear of presentation) and “random” presentation (ear of presentation varied randomly). Significantly faster left ear reaction times were obtained in the “expected” condition. The rank order of subjects' standard dichotic listening task scores correlated negatively with reaction time ear differences in the “expected” presentation condition. Results are discussed in terms of existing theories of response lateralization in simple reaction time tasks, and an expanded hypothesis is offered. Specifically, it is suggested that two or more distinct but potentially overlapping mechanisms may be responsible for observed asymmetries in monotic auditory perception. Both an attentional or lateralized motor response bias and an inherent lateralization of function may operate side by side, differentially activated by task demands, mode of stimulus presentation, and nature of stimuli.     

“Sleeper effects” in development: Fact or artifact?

The evolution of the concept of “sleeper effects” is traced from the work of J. Kagan and H. A. Moss (Birth to Maturity. New York: Wiley, 1962) to the present time. The phenomenon was originally inferred, without cross-validation, in the domain of personality, from correlations with early events which were stronger late in development than earlier. More recently it has been extended to account for long-term attainment differences associated with the presence or absence of preschool intervention. It seems possible that the original evidence may have capitalized upon chance fluctuations of few among many correlations. What is more certain, however, is that as currently used the term is imprecise, usually unjustified, and irrelevant to the supposed later effects of brief early intervention.     

Personality and the topography of the conditioned eyelid response

One-hundred and four women were tested on an eyelid conditioning paradigm in a 2 x 2 x 2 factorial design where two levels of US intensity (1 vs 3 p.s.i.) were balanced against two rest pause interpolations (after 25 and after 50 trials), and the presence or absence of a warning stimulus prior to CS-US presentation. Subjects were later classified as high, low or intermediate extraverts on the basis of a personality questionnaire. A very detailed analysis of conditioned responses was carried out, using both simple and composite measures including work-ratio, utility-ratio, CR frequency, peak latency, peak amplitude, response area and effective response area, degree of avoidance amplitude and latency, etc. Major findings related to similar effects of high intensity US vs low intensity US, and introversion vs extraversion; introverts react as if they were responding to more intense stimuli than extraverts. This finding cuts across other parameter variables, and supports Eysenck's formulation of personality-conditioning relationships in terms of higher cortical arousal in introverts as compared with extraverts.     

Mobility among young workers in a multi-ethnic community

The job experiences of a group of young people of English and Pakistani origin who had left school four years earlier at the age of 16 were investigated using interviews and retrospective data from careers-office files. Job-changing had been frequent during the first 18 months of employment, with changes being largely of a non-promotional kind. Those who had experienced regular non-promotional job-change tended to have had low attainment in basic educational skills and inadequately developed vocational attitudes and personalities when leaving school. Yet in the majority of cases early mobility had led to stability by the end of the fourth post-school year. It is suggested that early job-changing may serve a positive function for the individuals concerned Implications for careers guidance in school are discussed.     

Do tough-minded people hold tough-minded attitudes?

Eysenck originally postulated that extraverts would adopt tough-minded social attitudes, although psychoticism is now considered to be of greater importance than extraversion. Previous research has attempted to relate psychoticism to realism-idealism, a principal factor of the Wilson-Patterson Conservatism Scale, and a measure of tough-mindedness acceptable to Eysenck. Results have proved discrepant; authors have used psychoticism scales of uncertain item content and length. The present study examines the relationship between psychoticism, extraversion and realism-idealism, using the Eysenck Personality Questionnaire and the Wilson-Patterson Attitude Inventory. The results provide only weak support for Eysenck’s theory. A more significant relationship was obtained between psychoticism and conservatism, and extraversion and conservatism, although a theoretical rationale for these relationships is lacking.     

Behavior modification and human rights: A legacy of Edward Stanton Sulzer, 1930-1970

Edward Stanton Sulzer was born in New York City on June 4, 1930. He attended school in Laureltown, N.Y., until the age of 15, when, after two years of high school, he was admitted into the University of Chicago. Leaving prematurely due to his mother's death, he returned to New York to work in film production. Sulzer completed his undergraduate work at the City College of New York, studying film production and psychology. In 1953 he entered the doctoral program in clinical psychology at Teachers College, Columbia. Spending two years in the Army during his graduate training, his work was completed in 1958. He then joined the faculty of the Upstate Medical School of the State University of New York, Department of Psychiatry, moving on two years later to the Psychiatry Department at the University of Minnesota. In 1965 Sulzer moved to assume the directorship of the Behavior Modification Program, in the Rehabilitation Institute at Southern Illinois University, where he remained until his death on February 28, 1970.In observance of the 10th anniversary of the death of Edward Stanton Sulzer, these reminiscences are presented. They describe how an individual psychologist could affect the professional and personal lives of many. Edward Sulzer is described in terms of the environment that shaped his values, how they affected the actions of his students and clients, and how they are reflected in current social policy. The account leads to a conclusion that the actions of single individuals may influence the course of human events.
