Complexity and colour preferences in chicks of different ages

Five- and six-day old chicks were found to prefer a complex stimulus to a simple one, whilst 2-day old ones showed no such preference; but a red stimulus, whether simple or complex, tended to be preferred at both age levels when it was paired with a non-coloured complex stimulus. Preference for complexity may be usefully viewed in any species in the context of the behavioural development of the individual.     

A COMPARISON OF NORTH-AMERICAN AND BRAZILIAN COLLEGE STUDENTs' PERSONALITY PROFILES ON THE 16 PF QUESTIONNAIRE

Le questionnaire de personnalité 16 PF (Forme A) a été traduit en portugais et soumis à un échantillon représentatif des étudiants de Sao Paulo (Brésil), comprenant 770 H et 555 F. Pour chaque facteur, les résultats ont été comparés à ceux d'un échantillon standardisé d'étudiants américains: les étudiants brésiliens sont, en général, moins sociables (A —) et moins enthousiastes (F —), plus soupçonneux (L +) et plus imaginatifs (M +); ils sont également moins conservateurs (Qi +) et plus indépendants (Q2 +). l'analyse de second ordre fait apparaître les Brésiliens comme plus anxieux et plus introvertis, montrant également plus de spontanéité et de créativité que les sujets américains. On constate enfin l'existence de différences entre hommes et femmes, tant à l'intérieur de chaque groupe qu'entre les deux échantillons.     

Discrimination of checkerboard patterns by rats

Fifteen rats were trained to discriminate between a regular checkerboard pattern and a similar pattern containing a “mistake.” The animals subsequently transferred to many other pairs of regular and irregular patterns differing widely from the originals. The results suggest that rats can induce and store highly abstract rules describing input patterns.     

The conceptual base view of categorization

An experiment was designed to show that some categories, called Type C categories, are mediated by an abstract, interpretively derived conceptual base. To this end, each of four groups of subjects ranked 10 sentences (instances) in terms of how well they illustrated the figurative meaning of a proverb (Proverb group), or how well they illustrated the meaning of an excellent interpretation of the proverb (Excellent Interpretation group), or a poor interpretation of the proverb (Poor Interpretation group), or an unspecified, unstated underlying meaning (Control group). The Excellent Interpretation groups' rankings correlated highly with standard ranks established by the Proverb group, but the Poor Interpretation group's and the Control group's ranking were uncorrelated with these two group's rankings. Apparently, the subjects in the Proverb group accomplished their rankings by using a conceptual base or microtheory similar in meaning to the interpretation used by the Excellent Interpretation group. Discussion centered on the question of whether the Classical, Probabilistic, or Exemplar Views of categorization (Smith & Medin, 1981) could account for the results. It was argued that they could not, basically because Type C categories are more dependent upon interpretive processes than the more perceptually based Type P categories to which these views have traditionally been applied.IBM.     

What's That Smell?

In philosophical discussions of the secondary qualities, color has taken center stage. Smells, tastes, sounds, and feels have been treated, by and large, as mere accessories to colors. We are, as it is said, visual creatures. This, at least, has been the working assumption in the philosophy of perception and in those metaphysical discussions about the nature of the secondary qualities. The result has been a scarcity of work on the “other” secondary qualities. In this paper, I take smells and place them front and center. I ask: What are smells? For many philosophers, the view that colors can be explained in purely physicalistic terms has seemed very appealing. In the case of smells, this kind of nonrelational view has seemed much less appealing. Philosophers have been drawn to versions of relationalism—the view that the nature of smells must be explained (at least in part) in terms of the effects they have on perceivers. In this paper, I consider a contemporary argument for this view. I argue that nonrelationalist views of smell have little to fear from this argument.     

The Effects of Truth–Lie Base Rate on Interactive Deception Detection Accuracy

Consistent with the Park and Levine's (PL) probability model of deception detection accuracy, previous research has shown that as the proportion of honest messages increases, there is a corresponding linear increase in correct truth–lie discrimination. Three experiments (N = 120, 205, and 243, respectively) varied the truth–lie base rate in an interactive deception detection task. Linear base‐rate effects were observed in all 3 experiments (average effect r#x02009;= .61) regardless of whether the judges were interactive participants or passive observers, previously acquainted or strangers, or previously exposed to truths or lies. The predictive power of the PL probability model appears robust and extends to interactive deception despite PL's logical incompatibility with interpersonal deception theory.     

Towards a taxonomy of philosophical counselling

As sympathetic outsiders trying to understand and explain the field of philosophical counselling to other (perhaps not so sympathetic) outsiders, we find ourselves repeatedly asking and being asked two questions: “What is philosophical counselling?” and “What is its relationship to psychological counselling?” In seeking to develop satisfactory answers to these questions, we present a taxonomy of philosophical counselling. This fourfold taxonomy was developed by classifying the work of a range of recognised philosophical counsellors in terms of their declared ends. This taxonomy makes sense of the diversity of the field, while also recognising the underlying coherence. Moreover, the categories of the taxonomy align with existing forms of psychological counselling practice, and in this way the taxonomy enables us to pinpoint the relationship between psychological and philosophical counselling. We end with some consideration of what philosophical counsellors can learn from their colleagues in psychology, especially in relation to the role of empathy and the importance of empirical testing.
