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.     

An electronic audio switch

This article describes an electronic switch that allows presentation of sine wave stimuli without the often undesirable transient thump, thud, or click usually caused by ordinary electromechanical switches.     

The construction of a programmable olfactometer

A new type of multichannel olfactometer is described, and the results are given for gas chromatographical standardization of this equipment. The olfactometer keeps 24 odorous substances available for presentation, consecutively, two per trial, or combinations of the two. It produces concentrations of odorous gas in the air between 1 × l0^?5 and 1 × 10^?11 molecules/liter. The principle of construction is gradual dilution of an odorous gas in streaming purified air. The design provides for electronic control of stimulus sequence and response registration via punched tapes.     

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.     

Dimensional salience as a function of educational attainment and method of discrimination training

The effects of three methods of selective-attention training with 4-sided forms on the salience of an invagination physical dimension in discrimination judgments with a stimulus domain of 12-sided forms were examined for 6-year-old Ss of low and high educational attainment. The results demonstrated that training procedures involving perceptual demonstration or manipulation increase the invagination dimension salience in the 12-sided stimulus domain more than a verbal training procedure for low educational attainment Ss. Implications for the psychophysical study of relatedness of stimulus domains are discussed.     

Redistributing control between the elements of a compound stimulus

Twenty-eight pigeons were given discrimination training. Four groups were run in which for 0, 2, 4 and 9 sessions of training colour was an irrelevant cue and tone was relevant. Generalization tests were given in extinction; the training colour (C₁) and another colour (C₂) were presented with tone (T) and noise (N). Responding to these four stimulus combinations, TC₁, TC₂, NC₁ and NC₂, allowed the assessment of control by colour and tone. A reduction of control by colour and an increase in control by tone were found to be positively related to the amount of training with colour irrelevant. Tests showed a strong inverse relationship between control by colour and tone.
