Private events revisited: Does unobservable mean private?

This paper presents a discussion on the misapplication of the concept private events in traditional psychotherapy interpretation. Shown is that, logically, the term privacy is contradictory to principles of science and it further inhibits anaturalistic approach to observation. Evidence of so-called private clinical events are presented within an alternative model that obviates the role of privacy and encourages primarily an objective outlook on the events.     

Masked phonological priming effects in English: are they real? Do they matter?

For over 15 years, masked phonological priming effects have been offered as evidence that phonology plays a leading role in visual word recognition. The existence of these effects-along with their theoretical implications-has, however, been disputed. The authors present three sources of evidence relevant to an assessment of the existence and implications of these effects. First, they present an exhaustive meta-analytic literature review, in which they evaluate the strength of the evidence for masked phonological priming effects on English visual word processing. Second, they present two original experiments that demonstrate a small but significant masked priming effect on English visual lexical decision, which persists in conditions that may discourage phonological recoding. Finally, they assess the theory of visual word recognition offered by the DRC model (Coltheart, Rastle, Perry, Langdon, & Ziegler, 2001) in the context of their empirical data. Through numerous simulations with this model, they argue that masked phonological priming effects might best be captured by a weak phonological (i.e., dual-access) theory in which lexical decisions are made on the basis of phonological information.     

Report on work in progress: “Towards a new science of the human”

A multidisciplinary and global study of the evolutionary process of the universe in general and mankind in particular is proposed, drawing from both modern science, approached by taking into consideration its various interdependent aspects; and the study of western and eastern ancient traditions, which prove to have a common foundation that is the comprehension and the control of the evolutionary process itself.

Such a study will lead to the compilation of a “Corpus Unus” of the new science of the human, a science which does not belong to a race, a culture or an age, but is specific to the human being as such.

Such a science will imply the exploration of mankind and of the evolutionary process, and applying the results in a pragmatic way to the betterment of human beings, society, and universe.     

Simplicity: a unifying principle in cognitive science?

Much of perception, learning and high-level cognition involves finding patterns in data. But there are always infinitely many patterns compatible with any finite amount of data. How does the cognitive system choose 'sensible' patterns? A long tradition in epistemology, philosophy of science, and mathematical and computational theories of learning argues that patterns 'should' be chosen according to how simply they explain the data. This article reviews research exploring the idea that simplicity drives a wide range of cognitive processes. We outline mathematical theory, computational results and empirical data that underpin this viewpoint.     

Daily experiences and well-being: Do memories of events matter?

Retrospective subjective well-being (SWB) refers to self-reported satisfaction and emotional experience over the past few weeks or months. Two studies investigated the mechanisms linking daily experiences to retrospective SWB. Participants reported events each day for 21 days (Study 1) or twice a week for two months (Study 2). The emotional intensity of each event was rated: (1) when it had recently occurred (proximal intensity); and (2) at the end of the event-reporting period (distal intensity). Both sets of ratings were then aggregated across events and used to predict retrospective SWB at the end of the study. Path analyses showed that proximal intensity predicted retrospective SWB whereas distal intensity did not. The effect remained even after controlling for trait happiness and neuroticism. These results suggest that daily experiences influence retrospective SWB primarily through abstract representations of the past few weeks or months (as measured by aggregated proximal intensity ratings) rather than the explicit recollection of individual events during the same period (as measured by aggregated distal intensity ratings). Retrospective SWB, in turn, mediated the effect of daily experiences on global SWB (i.e., self-reported satisfaction and emotional experiences in general).     

Who remembers best? Individual differences in memory for events that occurred in a science museum

Individual differences in memory and suggestibility were assessed in an experiment involving 1989 people who attended the Exploratorium, a science museum located in San Francisco. Subjects watched a brief film clip of an assault and later answered questions about it. Approximately half received misinformation about some critical items. Four demographic variables (gender, educational level, age, and occupation) were examined to determine their impact on memory performance. The principle of discrepancy detection predicts that, compared to individuals with a good memory, people who have poor memory to begin with will be relatively suggestible (that is susceptible to misinformation). Some of our findings were consistent with this principle. For example, children (5–10 years) and elderly (over 65) were relatively inaccurate and also relatively suggestible. Other findings were not consistent with the principle, for example the finding that artists and architects were relatively accurate, but they were also highly suggestible.     

Motivational systems of social behavior in male rats and monkeys: Are they homologous?

A comparison is presented between the behaviors of male rats and male stumptail macaques that occur when two unfamiliar males are paired for 10 min. Results which have been presented in detail in separate papers elsewhere are compared and discussed here in terms of the hypothetical organization of motivational systems. The following motivational mechanisms appear to be homologous in the rat and monkey: offense, defense, submission, male sex, self grooming, and allogrooming. Two motivational mechanisms are analogous but not homologous: patrol/marking in the rat and display in the monkey. There is a shift in sensory modality of motivating stimuli from olfaction in the rat to complex visual and auditory stimuli in the monkey. There is also a shift in the modalities of motor patterns from predominant use of the mouth by the rat to use of the hands by the monkey. Both shifts affect most or all motivational systems of social behavior. It is hypothesized that the outer parts of motivational systems, their sensory and motor interfaces with the environment, change more rapidly and incrementally during the course of mammalian evolution than does the inner part, the integrational portion that consists of the motivational mechanisms.     

Disengagement beliefs in smokers: Do they influence the effects of a tailored persuasive message advocating smoking cessation?

Disengagement beliefs function to reduce cognitive dissonance and a number of predictions with regard to disengagement beliefs have been tested and verified. However, the influence of disengagement beliefs on persuasion has not been studied yet. In a field-experiment, 254 smokers were randomly assigned to a persuasive message condition or a no-information control condition. First, it was assessed to what extent disengagement beliefs influenced persuasion. In smokers with low adherence to disengagement beliefs, quitting activity (attempting to quit) in the control condition was high, but this was not further increased by persuasive information on the negative outcomes of smoking. In contrast, smokers who strongly adhered to disengagement beliefs showed low quitting activity in the control condition, but significantly more quitting activity when they received the persuasive message. Second, it was studied what smokers do when they experience negative affect caused by the persuasive message. The results show that in smokers who strongly adhered to disengagement beliefs, negative affect was associated with less quitting activity. Although these results show that quitting activity as assessed at 2 and 8 months follow-ups was influenced by disengagement beliefs, point prevalence seven-day quitting was not. This study shows that adherence to disengagement beliefs is a relevant individual difference in understanding effects of smoking cessation interventions.     

Do consumers ever learn? Analysis of segment behavior in experimental markets

Economists argue that, despite cognitive limitations, economic agents arrive at optimal choice rules by learning. The assumption is that consumers, for example, are adaptively rational. Adaptive rationality raises a host of issues. We address three of these in the context of experimental markets: do consumers differ on the basis of learning; how do these differences, when aggregated, affect market efficiency; and how do consumers learn? Analysis of our experimental data reveals the following. First, multiple segments of consumers exist on the basis of learning. Second, the largest segment consists of subjects who do not learn despite timely feedback and motivation. Third, although some consumers do learn to make optimal choices, the effect of this segment on market efficiency is cancelled by an equal number of subjects who ‘learn' false relations. Finally, although subjects do not learn strict rationality even with experience, they are in the aggregate not so irrational as to allow highly suboptimal brands to survive. Further analysis of how consumers learn, specifically on the cues (signals) and the rules consumers employ in making choices over time leads to the following two conclusions. First, some signals make learning more easy than others: for example, providing market share information improves learning but not as much as providing quality information does. Second, people employ different rules depending upon the type of information they have. For example, consumers making decisions based only on price information are more likely to use a heuristic like ‘buy a medium‐priced product provided it has not failed in the past'. Consumers making decisions based on price and quality information may employ a heuristic such as ‘buy top quality products regardless of price'. We discuss the implications of these findings for theory and practice. Copyright © 2000 John Wiley & Sons, Ltd.     

Do I belong?: it depends on when you ask

A feeling of belonging to an academic context is a critical determinant of academic achievement and persistence, particularly for students of color. Despite the fact that students of color are generally more susceptible to fluctuations in belonging uncertainty than White students, survey design can unintentionally mask this reality. We investigated whether context effects undermine the accurate assessment of belonging uncertainty in junior high and high school students (Study 1) and college students (Study 2). Considering one's ethnic identification (Study 1) and personal experiences with discrimination (Study 2) threatens sense of belonging in students of color, but not White students. Researchers should consider question order within surveys so as not to artificially mask belonging uncertainty in students of color.     

Machiavellian managers: Do they perform better?

This study investigates the relationship between Machiavellianism and job performance, as measured by sales per square foot, gross margin percentage, and inventory turnover, among 60 retail store managers. Except for a significant relationship between male store managers' gross margin percentage no other relationships were observed between Machiavellianism and job performance. Several explanations for the absence of significant relationships were discussed.     

Contralateral and heteromodal interaction effects in somatosensation: Do they exist?

In this paper we concern ourselves with the problem of whether or not conditioning stimuli of other modalities or stimuli applied to a distant locus of the body interact with a sensitive test of somesthetic temporal acuity we have called the gap test. The results of the experiment indicate that visual stimuli do not exert an observable influence on this temporal judgment, but that auditory stimuli and contralateral stimulation in the same modality do show a significant but relatively small effect. This is compared and contrasted with the very large and persistent effect reported when the conditioning stimulus is applied to the same electrodes as the gap test. By comparing our results with experiments of similar design carried out on lower animals by other investigators, some insights into the neural localization of the reported effects is obtained.     

Predicting a changing taste: Do people know what they will like?

A distinction is made between decision utility, experienced utility, and predicted utility and an experiment is reported addressing people's ability to forecast experienced utility. Subjects in two experiments made predictions of their future liking for stimuli to which they were then exposed daily for one week. The stimuli were ice cream in a pilot study, plain yogurt in the main study, and short musical pieces in both studies. Decreased liking was the modal prediction, even when the true outcome was increased liking, or reduced dislike. There was substantial stability of tastes, but there were also substantial individual differences in the size and even the sign of changes in liking with repeated exposure. There was little or no correlation between the predictions of hedonic change that individuals made and the changes they actually experienced.     

Inattentive and noninattentive ADHD children: Do they constitute a unitary group?

Teacher-rated ADHD and normal control children were administered a continuous performance test (CPT), and were then further subdivided based upon the presence or absence of objectively assessed attentional deficits. In addition, children were assessed using several measures of cognitive and behavioral functioning. Attentional deficits were signficantly more prevalent among the ADHD group, but about half of the ADHD children showed no evidence of objectively assessed attentional dysfunction. Further group analyses indicated that ADHD children with objectively assessed attentional dysfunction appeared cognitively impaired, while ADHD children without objective evidence of attentional dysfunction had more conduct problems. CPT inattention was not related to the presence of cognitive impairments or conduct problems in the control group. These data must be considered preliminary because teacher ratings were the only source of diagnosis and a single measure of inattention was used. However, they suggest that two subtypes of ADHD children can be identified, one characterized by inattention and learning problems, and the other by conduct problems.The authors gratefully acknowledge the assistance of Sister Hildegard Kogler and the St. Francis DeSales School, and the parents and children who participated in this study.     

Do people remember the temporal proximity of unrelated events?

In the present study, we tested the ability to remember the temporal proximity of two unrelated events that had happened within 7 days of one another. In three experiments, 1,909 participants judged whether pairs of news events, ranging in age from 1 month to about 6 years, had occurred within a week of each other and, if not, how far apart they had occurred. Some event pairs were related, and others were unrelated. For unrelated event pairs, same-week and separation judgments were very poor. Accuracy was much greater for both kinds of judgments when the events were related. Participants often guessed the separation of unrelated event pairs, whereas they frequently deduced the separation or remembered the proximity of related event pairs. For both types of pairs, the participants reported using the strength of the memories or the general period in which the events had occurred.     

Do birds of a feather flock together in China?

Evidence of couple similarity was examined in 2 nationally representative samples (Ns = 536 and 537 couples) from mainland China. Variable‐centered and couple‐centered tests provided convergent results suggesting that husbands and wives were considerably similar on characteristics of 3 broad categories: demographic variables, values, and personality. Additional tests suggest that value and personality similarities were not likely to be due to social homogamy, convergence, response biases, or culture‐unique characteristics. Whereas the couple similarity on demographics and values largely mirrors what has been observed in Western research, Chinese couples' consistent and strong similarity on personality domains presents a striking contrast to Western couples who share little systematic similarity on personality.
