Relative accessibility of domain knowledge and creativity: The effects of knowledge activation on the quantity and originality of generated ideas

In brainstorming research, quantity is assumed to breed quality. However, little is known about the cognitive mechanisms underlying this relationship. A parsimonious explanation assumes a random process, in which every idea has an equal chance of being a high-quality (original and feasible) idea. In contrast, a ‘deep exploration’ approach suggests that the originality (but not the feasibility) of generated ideas is dependent on the degree to which people engage in deep exploration of their knowledge. We conducted two experiments to test the latter hypothesis. Prior to a brainstorming task, participants were primed with subcategories of the brainstorming topic. Priming caused a higher relative productivity and average originality within the primed subcategory, but did not affect global productivity and originality across categories. This effect was replicated in dyadic interactions. These results support the deep exploration hypothesis, and suggest that the relationship between quantity and quality is more complex than has previously been assumed.     

How Can People Be Induced to Willingly Change Their Behavior? The Path from Persuasive Communication to Binding Communication

How can people be induced to willingly change their behavior? The present article has three main objectives. Its first purpose is to review some of the procedures pertaining to the ‘free will’ compliance paradigm. These procedures increase the likelihood that others will freely comply to one's requests (low‐ball, teasing, foot‐in‐the door, touch, and ‘you are free to’ procedures). The second objective is to introduce a theory stemming from social psychology, namely, the theory of commitment. Finally, we wish to describe the binding communication approach that can be situated at the intersection of research conducted in both the fields of communication, more specifically in the domain of persuasive communication, and the fields of commitment and free will compliance. A project carried out to encourage school children to behave in a more environmentally friendly way will be described to illustrate the approach.     

Another look at dreaming: disentangling Freud's primary and secondary process theories

The Interpretation of Dreams contains Freud's first and most complete articulation of the primary and secondary mental processes that serve as a framework for the workings of mind, conscious and unconscious. While it is generally believed that Freud proposed a single theory of dreaming, based on the primary process, a number of ambiguities, inconsistencies, and contradictions reflect an incomplete differentiation of the parts played by the two mental processes in dreaming. It is proposed that two radically different hypotheses about dreaming are embedded in Freud's work. The one implicit in classical dream interpretation is based on the assumption that dreams, like waking language, are representational, and are made up of symbols connected to latent unconscious thoughts. Whereas the symbols that constitute waking language are largely verbal and only partly unconscious, those that constitute dreams are presumably more thoroughly disguised and represented as arcane hallucinated hieroglyphs. From this perspective, both the language of the dream and that of waking life are secondary process manifestations. Interpretation of the dream using the secondary process model involves the assumption of a linear two-way "road" connecting manifest and latent aspects, which in one direction involves the work of dream construction and in the other permits the associative process of decoding and interpretation. Freud's more revolutionary hypothesis, whose implications he did not fully elaborate, is that dreams are the expression of a primary mental process that differs qualitatively from waking thought and hence are incomprehensible through a secondary process model. This seems more adequately to account for what is now known about dreaming, and is more consistent with the way dream interpretation is ordinarily conducted in clinical practice. Recognition that dreams are qualitatively distinctive expressions of mind may help to restore dreaming to its privileged position as a unique source of mental status information.     

Correlations between attitude toward Christianity, prayer, and church attendance among 9- to 11-yr.-olds

Data provided by 150 9- to 11-yr.-old primary school pupils in England showed scores on the Francis Scale of Attitude toward Christianity more highly correlated with (personal) prayer (r = .57) than with (public) church attendance (r = .23), providing support for the view that attitude scales access a deeper level of religiosity less contaminated by those contextual and social factors which may influence public church attendance more than personal prayer.     

Levels of processing with free and cued recall and unilateral temporal lobe epilepsy

This study investigates the role of the temporal lobes in levels-of-processing tasks (phonetic and semantic encoding) according to the nature of recall tasks (free and cued recall). These tasks were administered to 48 patients with unilateral temporal epilepsy (right "RTLE"=24; left "LTLE"=24) and a normal group (n=24). The results indicated that LTLE patients were impaired for semantic processing (free and cued recall) and for phonetic processing (free and cued recall), while for RTLE patients deficits appeared in free recall with semantic processing. It is suggested that the left temporal lobe is involved in all aspects of verbal memory, and that the right temporal lobe is specialized in semantic processing. Moreover, our data seem to indicate that RTLE patients present a retrieval processing impairment (semantic condition), whereas the LTLE group is characterized by encoding difficulties in the phonetic and semantic condition.     

MANULEX: A grade-level lexical database from French elementary school readers

This article presents MANULEX, a Web-accessible database that provides grade-level word frequency lists of nonlemmatized and lemmatized words (48,886 and 23,812 entries, respectively) computed from the 1.9 million words taken from 54 French elementary school readers. Word frequencies are provided for four levels: first grade (G1), second grade (G2), third to fifth grades (G3-5), and all grades (G1-5). The frequencies were computed following the methods describedby Carroll, Davies, and Richman (1971) and Zeno, Ivenz, Millard, and Duwuri (1995), with four statistics at each level (F, overall word frequency;D, index of dispersion across the selectedreaders;U, estimated frequencyper million words; andSFI, standard frequency index). The database also provides the number of letters in the word and syntactic category information. MANULEX is intended to be a useful tool for studying language development through the selection of stimuli based on precise frequency norms. Researchers in artificial intelligence can also use it as a source of information on natural language processing to simulate written language acquisition in children. Finally, it may serve an educational purpose by providing basic vocabulary lists.     

Brief strategic family therapy: lessons learned in efficacy research and challenges to blending research and practice

In this article, we present key lessons that we have learned from (1) a long program of research on an empirically supported treatment, brief strategic family therapy (BSFT), and (2) our ongoing research and training efforts related to transporting BSFT to the front lines of practice. After briefly presenting the rationale for working with the family when addressing behavior problems and substance abuse in adolescent populations, particularly among Hispanic adolescents, we summarize key findings from our 30-year program of research. The article closes by identifying barriers to the widespread adoption of empirically supported treatments and by presenting current work within the National Institute on Drug Abuse's Clinical Trials Network that attempts to address these barriers and obstacles.
