Does subjective well-being show a relationship between parents and their children?

The relationship between the subjective well-being of parents and their own 12–16-year-old children was explored in a Spanish sample of N = 266 families. A positive relationship was expected due to both a shared environment and the possibility of the genetic transmission of subjective well-being ‘set-points’. A positive significant relationship was found for the summated scale of satisfaction domains forming the Personal Well-being Index, and for the specific domains of health and security for the future. However, no relationship was found for the other five domains that make up this Index or for satisfaction with life as a whole. We conclude while these results provide some evidence for the expected influence of a shared environment, they have failed to provide evidence for high heritability of set-points for subjective well-being.     

False recognition of facial expressions of emotion: causes and implications

This article examines the importance of semantic processes in the recognition of emotional expressions, through a series of three studies on false recognition. The first study found a high frequency of false recognition of prototypical expressions of emotion when participants viewed slides and video clips of nonprototypical fearful and happy expressions. The second study tested whether semantic processes caused false recognition. The authors found that participants made significantly higher error rates when asked to detect expressions that corresponded to semantic labels than when asked to detect visual stimuli. Finally, given that previous research reported that false memories are less prevalent in younger children, the third study tested whether false recognition of prototypical expressions increased with age. The authors found that 67% of eight- to nine-year-old children reported nonpresent prototypical expressions of fear in a fearful context, but only 40% of 6- to 7-year-old children did so. Taken together, these three studies demonstrate the importance of semantic processes in the detection and categorization of prototypical emotional expressions.     

External validation of the computerized, group administrable adaptation of the “operation span task”

One of the most widely used tasks for measuring working memory capacity is the operation span task (OSPAN; Turner & Engle, 1989). This task has almost always been applied individually, and stimuli presentation is controlled by the experimenter. Recently, De Neys, d'Ydewalle, Schaeken, and Vos (2002) improved the administration procedure by designing an automated, group-administrable version of the task (GOSPAN). They found GOSPAN to be reliable, and they also provided evidence on its validity (a significant positive correlation between GOSPAN and OSPAN scores). However, an external test of GOSPAN validity is still lacking. In this work, we present such a validation for the automated version, when the task is administered both individually (Experiment 1) and to groups (Experiment 2). There are abundant previous data on the relation between working memory capacity and reading comprehension. In this work, this relation is studied using an automated OSPAN version to measure working memory capacity. Given that our results are similar to those found using the original OSPAN, our data support the external validity of the automated version of the task. We also tested the reliability of the task and found high internal consistency in both experiments.     

Second-order conditioning of human causal learning

This article provides the first demonstration of a reliable second-order conditioning (SOC) effect in human causal learning tasks. It demonstrates the human ability to infer relationships between a cause and an effect that were never paired together during training. Experiments 1a and 1b showed a clear and reliable SOC effect, while Experiments 2a and 2b demonstrated that first-order extinction did not affect SOC. These results were similar to those found in animal and human conditioning and suggested that a similar associative mechanism could explain these effects. However, they can also be used to look into the underlying causal mental model people build and store while they are learning this task. From a cognitive view, overall results suggest that an independent rather than a chain causal mental model is stored after second-order learning in human causal tasks.     

MV-Algebras and Quantum Computation

We introduce a generalization of MV algebras motivated by the investigations into the structure of quantum logical gates. After laying down the foundations of the structure theory for such quasi-MV algebras, we show that every quasi-MV algebra is embeddable into the direct product of an MV algebra and a “flat” quasi-MV algebra, and prove a completeness result w.r.t. a standard quasi-MV algebra over the complex numbers.

Broadcasting of violence on Spanish television: a quantitative panorama

A quantitative analysis of broadcasted violence by the main television (TV) channels transmitting for Madrid (Spain) was carried out using a novel method that randomly selects fragments of delimited duration from TV broadcasts. The device selects acts of aggression shown in those TV extracts, and classifies them according to their type. There was a high incidence of aggressive acts, especially physical (particularly leading to death), in TV fiction: films, serials and promos. The device also allowed examination of the prominence of aggression in children's programs, as well as showing minimal variation in the number of aggressive acts over screened time intervals. The pattern of the collected data suggests that the broadcasting of violence on TV emphasizes the conflicting elements of social reality, reproducing it in fiction, news reports and children's shows.

Person‐factors in the California Adult Q‐Set: closing the door on personality trait types?

To investigate recent hypotheses of replicable personality types, we examined data from 1540 self‐sorts on the California Adult Q‐Set (CAQ). Conventional factor analysis of the items showed the expected Five‐Factor Model (FFM). Inverse factor analysis across random subsamples showed that none of the previously reported person‐factors were replicated. Only two factors were replicable, and, most importantly, these factors were contaminated by mean level differences in item endorsement. Results were not due to sample size or age heterogeneity. Subsequent inverse factor analysis of standardized items revealed at least three replicable factors; when five person‐factors were extracted, they could be aligned precisely with the dimensions of the FFM. The major factors of person similarity can be accounted for entirely in terms of the FFM, consistent with the hypothesis that there are no replicable personality types in the CAQ.
