A watched pot sometimes boils: a study of duration experience

The ‘watched pot’ phenomenon — the lengthening of duration experience when one is attentively and perhaps impatiently waiting for some event to occur — was studied in three experiments. In them, each observer attended for a duration of 270 sec to a liquid-containing beaker on an electrical burner. Observers who were told that the experiment concerned time perception (prospective paradigm) reproduced the duration as longer than those told that it concerned visual perception (retrospective paradigm). In the prospective paradigm, reproductions were longer if the liquid did not boil than if it did, and an interruption (task-unrelated questioning) shortened reproductions if the liquid did not boil but had no effect if it did. In the retrospective paradigm, if there was boiling or questioning or both, reproductions were longer than if there was neither. Results have implications for hypotheses about duration experience.     

Within-compound associations in a variety of compound conditioning procedures

Three experiments used a flavor-aversion preparation to demonstrate the occurrence of within-compound associations in various conditioning procedures. In Experiment 1 rats first received two separate two-flavor compounds, each followed by a mild US. They then received one element from one compound paired with a strong US and one element from the other compound nonreinforced. A subsequent choice test of the other two flavors from the compounds revealed that the consumption of each test flavor reflected the conditioning history of the element with which it had been paired. Rats drank less of the flavor whose associate had been paired with the strong US than of the flavor whose associate had been nonreinforced. In Experiment 2 within-compound associations were observed using a similar design in a blocking procedure in which one element from each of the two compounds was conditioned previously. Experiment 3 identified within-compound associations in a procedure where reinforced single element presentations were intermixed with nonreinforced compound presentations, as in a conditioned inhibition paradigm. These results suggest that within-compound associations occur in several important conditioning procedures which use multiple CS presentations.     

The comparative effectiveness of two modes of observer training on the Staff-Resident Interaction Chronograph

The comparative effectiveness of two time-limited modes of training observers to code activity on the Staff-Resident Interaction Chronograph (SRIC) in residential treatment programs for mentally disabled adults was evaluated. The susceptibility of training procedures for consensual observer drift was also examined, as was the predictability of SRIC mastery from trainee characteristics. Two equated groups of undergraduate student trainees (N=15 each) participated in full-time training for 27 days, followed by two weeks of criterion testing in vivo and on videotapes. One group received training by experience personnel using procedures known to be effective (original method). The other group received training via a previously untested set of written and videotaped procedures that do not rely on experienced personnel (package method). Multivariate and univariate analyses of variance found both methods to be equally effective in the degree of mastery achieved by trainees, without evidence of observer drift. No meaningful predictions of coding mastery were found, but conceptual mastery was predictable from individual characteristics. Differences were obtained for both groups between in vivo versus videotaped criterion tests. The results document procedures that are both efficient and resistant to invalidity for complex observational methodology as well as feasible for standardizing assessment of staff functioning across residential settings.This article is based on a thesis submitted to the Graduate College of the University of Illinois at Urbana-Champaign in partial fulfillment of the requirements for the Ph.D. degree in psychology by the first author under direction of the second author. The third and fourth authors also participated as supervisors. Appreciation is extended to other members of the thesis committee, Fred Kanfer, W. Robert Nay, Julian Rappaport, and James Wardrop, for their comments and recommendations.

The effect of instructions on the apparent reversal of rotary motion in depth

This study concerns experimental investigation of the effect of instructions on the apparent reversal of rotary motion in depth. It was found that subjects instructed to report apparent reversals of an elliptical shape signalled more reversals than subjects who were instructed to report the non-occurrence of reversals. This difference increased over four trials. When the stimulus object was a trapezium window instructions to report reversals led to a higher rate of reversals than did instructions to report non-occurrence, but this difference did not increase significantly over trials.     

Sentence production and working memory

Previous research has shown that subjects can make up sentences faster from related noun pairs than from unrelated pairs. Two experiments tested the proposal that for the related pairs a subject simply has to access stored information but must make up an appropriate relation for unrelated pairs. In both studies the subjects were asked on some trials to remember a digit preload while they made up their sentences. Contrary to an initial prediction, the latencies were faster rather than slower with a preload. Furthermore, a surprise recall test at the end of Experiment 2 showed that there was no difference in the recall of related and unrelated pairs. The results were interpreted as evidence that semantic work was necessary for both types of noun pairs, and that the subjects did less semantic work with a digit preload. This interpretation was further supported by the finding that with the preload the subjects produced a narrower range of semantic relations between the noun pairs.

Abstract

Psychoanalysis has almost disappeared from the curricula of most American universities, which I illustrate by the case of the department of psychology at my own university, Harvard. Courses on psychoanalysis are very rare there and it is mostly seen as a part of history of psychology and not as a set of ideas that can be useful nowadays. Personality models developed by Freud or Melanie Klein, as well as many more contemporary psychoanalysts, are, however, still very relevant for the humanities. This is particularly the case for Shakespeare studies and I am trying to show that despite the fact that psychoanalysis can enrich this field, less and less students show interest in it or are willing to admit that they themselves may have unconscious reactions. I focus on the usefullness of the concept of projective identification and propose the thesis that is another name for the activities of theater, and indeed for theater itself.     

Propension à discriminer à l’égard du genre et dominance sociale

This work aims to study the propensity to discriminate (PTD) (Dovidio & Helb, 2005 ; Tisserant, Wagner & Barth, 2010) against gender and other salient criteria in the working place, such as ethnic origin and religious background. More precisely, we investigated the link between PTD and the social dominance orientation (Sidanius & Pratto, 1999). 119 counsellors from French employment services answered a questionnaire dealing on concepts and attitudes towards social groups. Results show that social dominance, as a system of belief justifying social inequalities, generally predict the PTD of individuals, whatever the criterion of discrimination considered. The sex of counsellors can be considered as a moderating variable since females are less likely to accept inequalities than males do. We discuss the need for work and organizational psychologists to invest, alongside the managers, this field of research on equality, non-discrimination and diversity (ENDD).
