CULTURAL DIFFERENCES IN REACTION TO FAILURE1

Les Occidentaux admettent qu'on critique leur performance; ils réagissent en général à la critique en essayant de faire mieux. En Extrême-Orient, il n'est pas convenable de dire à quelqu'un qu'il a échoué en quelque chose; le faisant, on a toute chance de le voir renoncer ou faire plus mal encore. Cette différence de comportement dans les deux civilisations s'explique par des différences d'organisation cognitive. Les AA. ont comparé, dans trois groupes d'étudiants de culture différente (Américains; Extrême-orientaux suivant les cours d'universités américaines; Thais de Thaïlande), les individus qui ont réussi et ceux qui ont échoué dans leurs études. Les sujets américains réagissent à l'échec en réduisant les relations entre toutes les variables étudiées, ce qui constitue un mode de défense en profondeur par le biais d'une organisation plus souple. Les sujets des deux autres groupes réagissent à l'échec par une réduction des contacts personnels et une rigidité accrue de l'organisation personnelle interne. Ces résultats ont une grande importance pratique relativement aux effets sociaux du développement économique en Extrême-Orient.     

Dynamic visuometric techniques

A general technique is described to automate the measurement of visual thresholds. The method is based on the dynamic analog of the method of adjustment, incorporating continuous feedback. Threshold is treated as a system interaction between some level of response and sensed input. The S tracks a stimulus that continually oscillates in magnitude around threshold. The accuracy and variability of the S’s response provides a dynamic and functional assessment of the threshold under the condition of the experiment. Techniques for instrumenting several visuometric procedures are described.     

A primate restraint and handling system for auditory research

A set of devices is described that enables daily handling and restraint of large primates. The animals live in cages and wear a special collar that fits into a modified primate restraining chair. A chain and pole arrangement simplifies the daily chairing procedure. A method of head restraint and earphone mounting is also described.     

Minicomputers

The characteristics and costs of minicomputers are discussed along with peripherals, time-sharing, and turnkey systems. The article concludes with a survey of over 100 small computer systems.     

Tables of event sequences for sequential analyses of data in psychological experiments containing two-class events

Tables of sequences of two-class events are presented for use in programming psychological experiments in which behavior on trial n may be a function of the events of trials n ? 1, n ? 2, and/or n ? 3. Various factors related to schedule generation are discussed, i.e., restrictions on trial-block length which accompany sequential balance, interrelationships of trial blocks in the multiblock experiment, relationships between run length and r-tuple occurrences, and alternation behavior. Following a consideration of various methods of schedule generation for the two-class experiment, it was concluded that no method can result in schedules that possess all properties considered desirable in psychological experiments. However, the present sequences allow for sequential balance and analysis, and thus should prove useful in producing schedules in some contexts that are standard with regard to sequential influences.     

Do depth shifts resulting from an interocular delay in stimulation result from a breakdown of binocular fusion?

Previous studies have shown that the introduction of an interocular delay in presentation to the two eyes of a briefly viewed, haploscopically presented object resulted in a rearward shift in the depth position of this object. The present study investigated the magnitude of this depth shift as a function of flash duration and determined the relationship of this magnitude to two-flash and simultaneity thresholds. It was found that depth shift magnitude decreased as flash duration increased, and that large depth shifts were associated with large two-flash thresholds. The hypothesis that depth shifts can occur within the temporal limits of binocular fusion was supported.
