Group and individual riskiness were compared on $2 “win” best at the race track. Using the standard pretest-posttest risk-shift design, group discussion to unanimous decision was found to produce a cautious shift in group bets. 相似文献

Critical examination is made of the recent controversy over the value of Monte Carlo techniques in nonmetric multidimensional scaling procedures. The case is presented that the major relevance of Monte Carlo studies is not for the local minima problem but for the meaningfulness of the obtained solutions. 相似文献

The present study outlines a theory of how people compare sentences against pictures. This theory was tested in four experiments in which Ss were timed as they judged whether a sentence (e.g., Star isn't above plus) was true or false of a picture (e.g., +∗). The latencies in these tasks were consistent with the thesis that: (1) sentences are represented in terms of elementary propositions; (2) pictures are encoded in the same interpretive format; (3) these two codes are compared in an algorithmic series of mental operations, each of which contributes additively to the response latency; and (4) sentence encoding, picture encoding, comparing, and responding are four serially ordered stages, and their component latencies are additive. From these results, it was also possible to rule out certain explanations based on visual imagery, conversion (e.g., converting isn't above into is below), reading time, normative word frequencies, and other factors. Finally, it was shown that this theory is consistent with previous studies on sentence comprehension, sentence verification, concept verification, and other related phenomena. 相似文献

Moscovici and Zavalloni (1969) suggest that both risk shifts and attitude shifts after group discussion are examples of a general group tendency to polarize opinions. In the present experiment, using both attitude and risk items, group discussion did not make individual opinions more extreme; only the group average became more extreme. This group extremity increase was not simply a more general way of conceptualizing the directional shifts in attitude and risk; group extremity increase appeared to be an effect of discussion that was independent of the risk and attitude shifts. Also, subjects in the co-working pretest of the standard risk-shift paradigm were found to be less extreme and more ‘agreeing’ than pretest subjects who were truly alone. This co-working/alone difference persisted after discussion and was not related to group extremity increase. On both attitude and risk items, group extremity increase was strongly correlated with group opinion convergence. It is argued from this correlation that group extremity increase may be an effect of some aspect of conformity influence. 相似文献

Development and validation of brief measures of positive and negative affect: the PANAS scales 总被引:95,自引:0,他引:95
In recent studies of the structure of affect, positive and negative affect have consistently emerged as two dominant and relatively independent dimensions. A number of mood scales have been created to measure these factors; however, many existing measures are inadequate, showing low reliability or poor convergent or discriminant validity. To fill the need for reliable and valid Positive Affect and Negative Affect scales that are also brief and easy to administer, we developed two 10-item mood scales that comprise the Positive and Negative Affect Schedule (PANAS). The scales are shown to be highly internally consistent, largely uncorrelated, and stable at appropriate levels over a 2-month time period. Normative data and factorial and external evidence of convergent and discriminant validity for the scales are also presented. 相似文献

Diurnal variation in the Positive Affects 总被引:2,自引:0,他引:2
We examined the circadian rhythm of two basic dimensions of mood—Positive Affect (PA) and Negative Affect (NA). Subjects were 196 college students in two studies who completed a mood rating form approximately seven times a day for 1 week. Significant diurnal variation was found to exist in overall Positive Affect, and in four component content areas, but not in Negative Affect. Specifically, all components of PA rose sharply from early morning until noon, remained relatively constant until 9 p.m., and then fell rapidly. The rise and fall of PA were quite robust across subjects, but the apparently static level of PA from noon to 9 p.m. was shown to result from averaging across marked individual differences in the time of peak PA. Various potential sources of these individual differences—“morningness-eveningness,” introversion-extraversion, and neuroticism/dysphoria—were investigated. Neither of the personality variables accounted for the significant variation in diurnal mood patterning, but clearly defined morning and evening types did show different patterns. Possible links between the mood pattern obtained and biologically based circadian rhythms, which have been postulated to be dysregulated in depression and mania, are discussed. 相似文献
