Prior stimulation and the perception of causality

An attempt was made to discover whether, in conditions similar to those of Michotte, the number of causal responses given by subjects was influenced by stimulation during the period just before the main experiment. Time-intervals between the arrival of object A and the departure of object B were systematically varied within the range 60 to 390 msec. Those who had earlier been exposed to shorter time-intervals (60 to 210 msec.) gave fewer causal responses than those who had been exposed to longer ones (150 to 300 msec. and 240 to 390 msec.). A possible explanation is offered in terms of the modification of existing “schemata.”     

Adolescents: A Suppressed Minority Group

The recent antagonistic but equally meritorious arguments concerning the nature of the adolescent necessitates a new framework of analysis which would incorporate these apparent antagonisms. Cursory observations indicate that more fruitful results may be obtained if the adolescent is equated to a member of a suppressed minority group. A comparison of the characteristics of the adolescent peer group to those of a suppressed minority group reveals some striking similarities.
