EXAMINATION OF SITUATIONAL AND ATTITUDINAL MODERATORS OF THE HESITATION AND PERFORMANCE RELATION

The hesitation dimension of action-state orientation refers to the behavioral capacity to start action on tasks. In this study, job characteristics (autonomy and routineness) and job attitudes (satisfaction and involvement) were examined as moderators of the relation between hesitation and supervisor ratings of work behaviors (overall job performance and self-management performance) in 2 different samples. In both samples, routineness moderated the hesitation and self-management performance relation such that individuals low in hesitation performed better than individuals high in hesitation when routineness was low, but no differences in performance were observed when routineness was high. In addition, job satisfaction and job involvement were significant moderators of the relation between hesitation and self-management performance, with individuals low in hesitation performing better than individuals high in hesitation when satisfaction or involvement was low, but no differences in performance were observed when satisfaction or involvement was high.     

Reaction times as a measure of uncertainty

In this article, a method is presented to analyse relationships between detection or discrimination frequencies and reaction times in psychophysical tasks. It is shown in three empirical data sets that reaction time decreases as a linear function of the absolute value of the logit transforms of the response probabilities. Such a function stresses the characteristic uncertainty associated with subjects' responses and the relation between their response parameters and the response criterion used by the subjects.     

Double threshold orders: a new axiomatization

The paper presents some new results concerning the axiomatization of double threshold preference structures. Such structures, which have been introduced in order to model a situation of hesitation between the strict preference and the indifference, were not axiomatized through the use of a single characteristic relation. We give two theorems for this purpose, exploiting a four valued logic recently introduced by the authors as a preference modeling language under hesitation. © 1998 John Wiley & Sons, Ltd.

Age, information processing speed, and intelligence

Two parallel, but independent, literatures have grown out of observations that individual differences in information processing speed, as expressed in performance on choice reaction time (C RT) tasks, modestly correlate with individual differences in age and IQ test performance. These associations have prompted theories that individual differences in information processing speed functionally determine individual differences in performance of all cognitive skills by people of different general intellectual ability (Eysenck, 1986; Jensen, 1985) or age (Salthouse, 1982, 1985).

The experiments on which this literature has been based suffer from methodological weaknesses, such that comparisons have only been made very early in practice and have only concerned mean latencies for correct responses. An experiment compared 90 volunteers aged from 50 through 79 years who were grouped in terms of their performance on the AH 4 (Heim, 1968) IQ test. It explored the joint and independent effects of individual differences in age and in IQ test score and the effects of practice on mean latencies (C RTs) on the shapes of distributions of correct and incorrect responses and on the limiting speeds with which accurate responses can be made (speed/error trade-off functions). We suggest that a plausible explanation for the results is that individual differences in age and in general ability influence C RTs mainly because they affect the efficiency with which responses can be controlled to maximize speed while maintaining accuracy.     

The development of children's achievement-related expectancies and subjective uncertainty

Children between the ages of 3 and 6 years were asked to predict their success or failure in two different tasks: a box-lifting task and a task in which marbles had to be rolled through gates of different widths. Both tasks had five difficulty levels which were presented either simultaneously or successively. Along with the verbal or nonverbal responses to questions about their chances of success, the time children needed to make the prediction (decision time), the number of eye movement during the decision time, and, in the box-lifting task, the time taken to approach the box were assessed. The results indicated that children from 3 years on make realistic assessments of their chances for success at the five different difficulty levels. The simultaneous presentation mode enables the children to make more realistic success predictions only in the marble-rolling task. For the box-lifting task, children seem to have a stabilized difficulty scale which allows sure predictions without the whole range of difficulty levels being physically presented.     

Commitment and rival attractiveness: Their effects on male and female reactions to jealousy-arousing situations

The present study explored the way in which males and females are affected by a rival's attractiveness and by the commitment to an alternative relationship in jealousy provoking situations. Subjects, who were all married between 5 and 20 years, read experimental vignettes and rated the protagonist's likely responses. Further, data on several personal variables (e.g., dispositional jealousy; self-esteem and quality of marital relationship) were collected. The data indicate that responses to the vignettes were mediated by an interaction between the rival attractiveness, the degree of commitment to alternative relationships and subject's gender. Male responses appeared to be driven by their concern with protecting their egos; females, on the other hand, seemed most concerned with protecting their relationships. The implications of the findings are discussed.     

Processing of proprioceptive information in Parkinson's disease patients

The present study is concerned with a comparison of Parkinson's disease patients and normal subjects on a number of simple and choice reaction time tasks in accordance with Sternberg's interactive procedures. The results indicated that the motor disorder in Parkinson's disease was at the level of output processing and related to the inability of central mechanisms to select and organize responses. Further, the results suggested that patients had difficulty in formulating complex plans or programmes for action.     

Le psychologue face au Covid-19 : enquête exploratoire sur les pratiques en distanciel

The context of the health crisis has led psychologists working in institutions or in private practice to adapt their working methods to the constraints of confinement, in particular by resorting to distance learning. This exploratory survey aims at documenting this evolution of practices, in collaboration with COVID 19. An online survey was conducted among practitioners, resulting in 397 responses. The questions concerned the use of telepsychology (time, activity), before, during and after the crisis period. While the use of telepsychology was infrequent before the crisis, almost three-quarters of the psychologists used it during the crisis, and slightly less than half thought they would use it afterwards. The amount of time devoted to these practices depends on the tasks and the status of the psychologist. It is more important for administrative tasks and meetings than for treatment, and more often envisaged by freelance psychologists than by employees. Beyond the general findings, taking into account the status and the field of activity allows a picture of the evolutions in progress.     

Time of day effects in simple repetitive tasks: Some possible mechanisms

A brief review of the literature, and three experiments, are presented which investigated time of day effects in human performance at simple repetitive tasks (i.e. tasks involving little or no ‘working memory’ load) The goal was to differentiate between a ‘capacity’ based explanation of the effects, concerned with changes in the general rate of information processing, and a ‘strategy’ based one concerned with the amount of information processed at each decision point. The strategy based explanation appeared to be the more suitable, accounting for the surprising heterogeneity in time of day function that was found for such tasks in the literature, and for the results of the three experiments. It would appear that there might be a general tendency for people to become faster but less accurate as the day wears on.     

Children's understanding of class inclusion hierarchies: the relationship between external representation and task performance

Three experiments were designed to investigate children's understanding of class inclusion hierarchies and to determine whether such understanding may be related to children's ability to construct external representations for information that was hierarchical in nature. Understanding of hierarchies was studied through tasks designed to demonstrate children's ability with subset/superset classification and knowledge of asymmetric and transitive relations. Children were asked to construct their own external representations for passages containing information that could be represented hierarchically. It was hypothesized that the quality of children's external representations would be related to their ability to respond to questions related to the passages. Children's responses to questions, as well as their external representations, suggested that children as young as second grade have substantial understanding of hierarchical relations. Although the external representations were constructed in drawing, written, or structured modes, the data revealed a strong relationship between the quality of children's external representations and their performance on question tasks requiring both recognition and reasoning. Finally, children understood the relationships expressed in tree diagrams and could construct such diagrams to respond to questions. Implications of the findings, particularly as related to note-taking skills, and suggestions for further research are discussed.     

Online shopping hesitation.

This study was designed to understand which factors influence consumer hesitation or delay in online product purchases. The study examined four groups of variables (i.e., consumer characteristics, contextual factors perceived uncertainty factors, and medium/channel innovation factors) that predict three types of online shopping hesitation (i.e., overall hesitation, shopping cart abandonment, and hesitation at the final payment stage). We found that different sets of delay factors are related to different aspects of online shopping hesitation. The study concludes with suggestion for various delay-reduction devices to help consumers close their online decision hesitation.     

Anticipatory and event related changes in heart rate as indicators of attention processes

The present study was concerned with the question of whether phasic event-related heart rate (HR) changes under easy intake conditions account for the association between anticipatory HR deceleration and task performance in a choice reaction time (RT) task with a fixed foreperiod. The task employed differed from simple RT tasks especially with regard to processing and attention demands. Subjects were required to determine as quickly and accurately as possible whether a probe, presented for 80 ms, was identical or not to one of two distinct memory items, presented at the onset of each trial. Reaction times as well as accuracy of responses were determined. The results of the present study were indicative of a reliable anticipatory HR deceleration which was related to latency of responses to the probe stimulus. Subjects with stronger decelerations reacted faster than subjects with diminished or missing decelerations. Furthermore a relation was found between this association and the heart rate changes to repeated presentations of a non-signal auditory stimulus under habituation conditions. Results were discussed in terms of differences in the regulation or control of attentional processes.     

The Role of Orthographic Neighborhood Size Effects in Chinese Word Recognition

Previous studies about the orthographic neighborhood size (NS) in Chinese have overlooked the morphological processing, and the co-variation between the character frequency and the the NS. The present study manipulated the word frequency and the NS simultaneously, with the leading character frequency controlled, to explore their influences on word lexical decision (Experiment 1) and naming (Experiment 2). The results showed a robust effect that words with a larger NS produced shorter reaction time than those with a smaller NS, irrespective of the word frequency and the tasks. This facilitative effect may occur due to a semantic network formed by neighbor words, resulting in the semantic activation to accelerate the word recognition. Moreover, the comparison of the effect sizes of word frequency between the two tasks showed that lexical decision responses demonstrated a larger word frequency effect, indicating that the sub-word processing was involved in the multi-character word recognition.     

Collaborative Teaching and Making Sense of Symbols: Comment on Lampert's "Knowing,Doing, and Teaching Multiplication"

Despite the progress research in cognitive science has made in the last few decades, it remains a challenge to demonstrate important practical benefits of this research. Too often it seems that the practical implications researchers can draw from their theories are either obvious to experienced practitioners or have small or tenuous effects in the real world. The article by Chandler and Sweller (1991) contrasts dramatically to this customary state of affairs: They apparently have found a simple characteristic of instructional materials that has dramatic effects on performance in real-world tasks. However, their article raises a number of deeper questions regarding the relation between research and application that will be the focus of this commentary. I argue that the best way to generate important practical results is to develop and test theories of mental processing that are concerned with variables and tasks that are important in the real world. Chandler and Sweller have not taken this approach, and this may limit the implications that can be drawn from their results.     

An Analysis of Early vs. Later Responses on a Divergent Production Task Across Three Time Press Conditions

Traditional assessments of divergent production have employed standard time press conditions of three minutes for measures of fluency, flexibility, and originality. Recent studies have provided evidence that the traditional time press condition may impede both fluency and quality of responses and that differences in divergent production responses have been found under a variety of creative prompting conditions. The purpose of the present study was to examine the effects of three time press and three creative prompt conditions on early vs. later trial originality scores for three divergent production stimuli. The participants were 91 undergraduate students enrolled in Educational Psychology courses who were randomly assigned to one of six experimental groups. The six groups were counterbalanced across the three vignette tasks in time press requirements and creative prompting. Aggregate differences were found in which there was a higher frequency of originality scores for the latter portions of trials as compared with the early portion of trials for all time press and prompting conditions.     

Striving for optimal relevance when answering questions

When people are asked "Do you have the time?" they can answer in a variety of ways, such as "It is almost 3", "Yeah, it is quarter past two", or more precisely as in "It is now 1:43". We present the results of four experiments that examined people's real-life answers to questions about the time. Our hypothesis, following previous research findings, was that people strive to make their answers optimally relevant for the addressee, which in many cases allows people to give rounded, and not exact, time responses. Moreover, analyses of the non-numeral words, hesitations, and latencies of people's verbal responses to time questions reveal important insights into the dynamics of speaking to achieve optimal relevance. People include discourse markers, hesitation marks, like "uh" and "um", and pauses when answering time questions to maximize the cognitive effects (e.g., a rounded answer is adequate) listeners can infer while minimizing the cognitive effort required to infer these effects. This research provides new empirical evidence on how relevance considerations shape collaborative language use.     

Switching between tasks and responses: a developmental study

Task switching requires the ability to flexibly switch between task rules and responses, and is sensitive to developmental change. We tested the hypothesis that developmental changes in task switch performance are associated with changes in the facilitating or interfering effect of the previously retrieved stimulus-response (S-R) association. Three age groups (7-8-year-olds, 10-12-year-olds and 20-25-year-olds) performed a two-choice reaction time (RT) task in which spatially compatible or incompatible responses were required. The RT costs associated with switching between tasks were larger when responses were repeated than when responses were alternated. Younger children showed a greater cost than adults when switching between tasks but repeating responses. This age difference decreased when the interval between the previous response and the upcoming stimulus increased. Switch costs were larger when switching to the compatible task than to the incompatible task, but this effect did not differ between age groups. These findings suggest that young children build up stronger transient associations between task sets and response sets, which interfere with their ability to switch to currently intended actions. A similar pattern has previously been observed for older adults (Mayr, 2001), suggesting a common contributor to task switching deficits across the life span.     

Consciousness is slower than you think

In easy serial choice reaction time tasks (CRT tasks) young adults can very rapidly "correct" nearly all their errors by making the responses that they should have made (error-correcting responses). They are much less accurate at signalling their errors by making the same, deliberate, response to each (error-signalling responses), and they poorly remember errors that they have not signalled or corrected. When instructed to ignore errors they nevertheless involuntarily register them because the response immediately following them (responses following unacknowledged errors) are unusually slow, and they sometimes make involuntary error correction responses. Errors that are neither signalled nor remembered are registered at some level because responses following unacknowledged errors are slowed. Old age does not impair the accuracy of error correction or reduce the proportion of errors that are acknowledged because they are followed by unusually slow responses, but it does reduce the accuracy of error signalling and of recall of errors. Groups of 40 young adults (mean age 20.1 years, SD 1.1) and 40 older adults (mean 71.2 years, SD 5.1) signalled and recalled their errors increasingly accurately as intervals between each response and the next signal were increased from 150 ms to 1000 ms. Error signalling and recall improved as response-signal interval (RSI) durations increased, reaching asymptote at RSIs of 800 ms for the young and 1000 ms for the older adults. Thus processes necessary for conscious and deliberate choice or error-signalling responses and for subsequent recall of errors require more than 150 ms to complete, are slowed by old age, and may be interrupted by onset of new signals occurring earlier than 800 to 1000 ms after completion of an incorrect response.
