Analyzing Additional Variables in the Theory of Reasoned Action

This study examined the convergent, discriminant, and predictive validity of several variables proposed to augment the theory of reasoned action (TRA), using both principal components analysis (PCA)/multiple regression and confirmatory factor analysis (CFA)/structural equation modeling (SEM) among a sample of the UK population regarding their intention to have a child. PCA revealed good convergent and discriminant validity for attitude vs. anticipated regret, subjective norm vs. moral norm vs. social relations, but not for intention vs. desire or perceived behavioral control. Multiple regression analyses showed that the additional variables predicted a significant increment in the variance in intention. CFA, however, showed moderate convergent validity and poor discriminant validity and the structural model comprised the 2 predictors from the TRA only.     

Predicting Affective Responses to Unexpected Outcomes

In decisions under uncertainty, decision makers confront two uncertainties: the uncertain linkage between actions and outcomes and the uncertain linkage between these outcomes and his or her affective responses to them. The two studies reported here examine affective responses to expected and unexpected outcomes in various settings. In Study 1, a scenario-based laboratory experiment (N = 149), we examined subjects' predicted responses to a range of outcomes, as a function of how surprising the outcome was. Study 2, a field study (N = 127), involved the expectations of bowlers about their scores in an upcoming game and about their responses to various outcomes at, above, and below expectations. We also measured actual affective reactions after the bowlers had completed their games. Findings suggest that subjects both expect and experience a loss-averse, expectation-based value function broadly of the Prospect Theory type. They also anticipate, and experience, an amplifying effect of outcome surprise, though they underestimate its size. We argue that such underestimation, together with overtight prediction ranges, may expose subjects to much larger affective variation with outcome variability than they anticipate.     

A call for a statement of expectations for the global information infrastructure

This paper considers the relationship between ethics, technology and law, and the roles and limitations each has in this relationship. It argues that ethics has the key role in establishing a resilient, comprehensive and sensitive information infrastructure. It puts forward a Bill of Rights and Responsibilities for the electronic community.

Discrimination by newborns of the intensity, frequency and temporal characteristics of auditory stimuli

The ability of 3- to 5-day-old neonates to discriminate between auditory stimuli, in terms of each of the dimensions of intensity, pitch and time, was studied using heart-rate responses in a habituation paradigm. For each of the dimensions a survey of the literature failed to provide results which could be used as the basis for later work involving auditory patterns. Further analysis of an earlier experiment (Stratton, 1970 a) involving stimuli at 80, 85 and 90 db showed that louder stimuli evoked larger initial responses and more rapid habituation. From the same experiment it was found that a change of pitch produced dishabituation as early as the 10th trial. There are reasonable grounds for attributing the increased response to the frequency characteristics rather than a change in the perceived intensity of the stimuli. Previous experiments suggested that fixed inter-stimulus intervals tended to produce anticipatory heart-rate changes and modify the magnitude and latency of the response. Two experiments designed specifically to examine temporal phenomena revealed time-linked behaviour. In both experiments acceleratory responses occurred at the first stimulus omission of a fixed-interval series. Not all of the subjects showed this effect, and in both experiments, only the subjects who failed to respond to the first stimulus presentation responded to stimulus omission. The findings are discussed in relation to general issues of neonatal psychophysiology, and it is concluded that neonates can discriminate in each of the auditory dimensions, but that preliminary work involving patterns should concentrate on varying pitch and intensity.     

Perspectivism as a Way of Knowing in the Zhuangzi

A perspectivist theory is usually taken to mean that (1) our knowledge of the world is inevitably shaped by our particular perspectives, (2) any one of these perspectives is as good as any other, and (3) any claims to objective or authoritative knowledge are consequently without ground. Recent scholarship on Nietzsche, however, has challenged the prevalent view that the philosopher holds (2) and (3), arguing instead that his perspectivism aims at attaining a greater level of objectivity. In this essay, I attempt a structurally similar reinterpretation of Zhuangzi’s perspectivism. I argue that while the Chinese thinker sees all knowledge as perspective-dependent, he thinks that some perspectives are broader and more accurate than others. He utilizes shifts in perspective precisely in order to attain these superior perspectives, which constitute what he calls da zhi 大知, or “greater knowledge.” Whereas Nietzsche sees his perspectivism as methodologically continuous with the sciences, Zhuangzi’s “greater knowledge” has the goal of ensuring our survival and well-being in the everyday world.     

Suggestibility effects persist after one year in children who experienced a single or repeated event

The study of long-term memory for repeated events has important implications for understanding autobiographical memory in a forensic context. Recall accuracy and suggestibility for details of an instance of a repeated event versus a single event were examined in children aged 5–6 and 7–8 years after a one-year delay. Children who reported an instance of a repeated event were more likely to report that a non-experienced detail had occurred and reported less correct information than did single-event children. After one year a significant suggestibility effect was still present. The present experiment provides further evidence for both the capabilities and limitations of children's long-term recall and reinforces the importance of non-suggestive interviews of children at all stages of investigation.
