Mood and realism of confidence judgements of one''s own answers to general knowledge questions

This study examines the effect of a depressed mood on the realism of subjects' confidence judgements of the correctness of answers to general knowledge questions. Research conducted on how mood influences cognitive processes gives reason to expect that a depressed mood might increase the realism of individuals' confidence ratings. Sixty subjects were divided into three conditions, two of which were given mood induction, one condition into an elated-happy mood and one condition into a depressed-sad mood. As evidenced by subjects' responses to mood scales only the depressed condition was affected by the mood induction. All subjects answered 93 general knowledge questions and rated their confidence in the correctness of the answer given. Subjects were instructed to think aloud when answering the last 31 questions. The conditions did not differ with respect to the proportion of questions answered correctly, mean level of confidence, nor with respect to three measures of the realism in subjects' confidence ratings (calibration, over/underconfidence and resolution). The results were the same when questions answered with and without think aloud instructions were analysed separately.

How great apes perform on a modified trap-tube task

To date, neither primates nor birds have shown clear evidence of causal knowledge when attempting to solve the trap tube task. One factor that may have contributed to mask the knowledge that subjects may have about the task is that subjects were only allowed to push the reward away from them, which is a particularly difficult action for primates in certain problem solving situations. We presented five orangutans (Pongo pygmaeus), two chimpanzees (Pan troglodytes), two bonobos (Pan paniscus), and one gorilla (Gorilla gorilla) with a modified trap tube that allowed subjects to push or rake the reward with the tool. In two additional follow-up tests, we inverted the tube 180° rendering the trap nonfunctional and also presented subjects with the original task in which they were required to push the reward out of the tube. Results showed that all but one of the subjects preferred to rake the reward. Two orangutans and one chimpanzee (all of whom preferred to rake the reward), consistently avoided the trap only when it was functional but failed the original task. These findings suggest that some great apes may have some causal knowledge about the trap-tube task. Their success, however, depended on whether they were allowed to choose certain tool-using actions. Electronic Supplementary Material Supplementary material is available for this article at     

Principled and statistical connections in common sense conception

Nominal concepts represent things as tokens of types. We report six experiments that investigate the nature of the relations we represent between the type of thing something is (e.g. DOG) and its other properties. The experiments provide evidence that we represent principled connections between the type of thing something is (e.g. DOG) and some of its properties (k-properties; e.g. having four legs for dogs), but not other properties (t-properties; e.g. being brown for dogs). Principled connections are different from logical, statistical, and causal connections. Principled connections, (i) license the expectation that tokens of the type will generally possess the k-property, (ii) license explanation of the presence of k-properties in tokens of a type by reference to the type of thing it is, and (iii) license normative expectations concerning the presence of the k-property in tokens of the type. The experiments provide evidence for all three of these aspects of principled connections. The experiments also demonstrate that principled connections must be distinguished from merely strong statistical connections. We suggest that principled connections are one of the fundamental types of relations (in addition to logical, statistical, and causal relations) in terms of which our conceptual knowledge is structured. We argue that principled connections reveal a formal mode of understanding and explanation. This mode of understanding complements other modes of understanding that have been studied within the theory-based approach to conceptual representation. Finally, we suggest that kind representations are distinguished from representations of mere types by the representation of principled connections to k-properties.

Political Psychology as Discipline and Resource

Around the 1960s, political psychology was developed as a field of knowledge that attempted to interrelate scientific psychology and political phenomena. However, social and academic conditions are very different today. More and more, political psychology is becoming a protagonist, as much in the internal context of psychology as in the external context of its relations with the social world. Thus, political psychology can now be seen as a resource relating psychological knowledge to social practice, and relating psychological processes to social action. Political psychology is the interface that puts psychology and society in contact. The development of political psychology in Spain provides an example of this alternative view of the field.     

Science, Values and the Human Dimensions

The presented paper substantiates the principle that values are an immanent component of science and any rational cognitive activity. This principle belongs to the European cultural tradition starting from the book of Genesis of the Old Testament, the values of certainty in the antique Greek philosophy and Francis Bacon's coincidence of knowledge and power. Values in science form complicated structures inconnection with different types of knowledge including “the knowledge that”, empirical evidence, various types of generalizations or rules, methods, directions, algorithms, “the knowledge how”, “the knowledge why” or other types of knowledge. Since the assignments of different types of values are the products of a decision-making, it is useful to distinguish many types of decision-making, especially semantic decision-making, information decision-making and decision-making with distinctly pragmatic dimensions. The values assignable to scientific activities and their results also include their social recognition, respect and prestige granted to knowledge and bearers of knowledge by society and social groups or communities. Knowledge generation and the rational and justified application of the achieved and acceptable impacts are also connected with decision-making procedures, values and criteria of social acceptance.

Relation of occupational knowledge to career interests and competence perceptions in Italian children

The relations of differential occupational knowledge with interests and competence perceptions in children as well as how these relations were moderated by gender and grade were examined in this study using an Italian sample. Data were collected from samples of elementary school and middle school children (N = 539). The Inventory of Children's Activities—Revised (ICA-R; Tracey & Ward, 1998) was used to assess children's interest and competency perceptions in various activities associated with the Holland's RIASEC types. The Occupational Knowledge Scale (OKS) was created for this study, and consisted of a representative sampling of occupational titles to which children indicated their knowledge. Hierarchical regression results indicated a relationship between knowledge, interests, and competence perceptions in children. With regard to overall knowledge, no relationship was found between general knowledge and either grade or gender. More specific examination of the type of knowledge as it varied across the dimensions of People–Things, and Data–Ideas demonstrated that there appeared to be a specific pattern relating interest, gender, and grade to knowledge of occupations. For knowledge of people relative to things occupations, higher interest, higher grade level, and being female predicts stronger knowledge of people occupations. It was also found that interest in ideas predicts stronger knowledge of ideas occupations, and being male predicts stronger knowledge of high prestige occupations. Generally, competence perceptions did not have a unique relation with one's knowledge of People–Things, Ideas–Data, or Prestige; however, girls who reported higher competence had greater knowledge of ideas occupations.
