Problems of Communication in Inter-American Programs

We use our own culture as a basis for interpreting the behavior of others and their failure to make responses we expect. Sometimes the nature of the problem soon becomes apparent but in other situations the causes may remain invisible. Certain problems may relate particularly to two characteristics of Latin American countries: the absence of our “puritanical” tradition and the presence of an elaborate system of “extended family” relationships we do not have. Counseling and guidance specialists may be affected by (1) the fact that teacher-pupil relationships include less of the “surrogate parent” element than in the U.S.; (2) difficulties students encounter in moving from one career choice to another; (3) the power of student organizations; and (4) an expectation that the specialist will provide definitive advice rather than help the student solve his own problems. Many Latin American students have negative images of North Americans; they “remember” history and tend to think in longer time blocks than are customary with us. A 10-year aid program, for example, may be seen as a short-range venture.     

Legitimizing Paltry Contributions: On-the-spot vs. Mail-in Requests1

Two versions of the legitimization-of-paltry-contributions technique (Cialdini & Schroeder, 1976) were compared with respect to their effectiveness in generating compliance with requests for charitable donations. When immediate, on-the-spot donations were requested, the technique significantly increased compliance rates relative to control conditions; but when the respondents were asked to mail in their contributions, virtually none did. The results offered some support for an image-maintenance explanation of the technique and were viewed as indicating that the effectiveness of the technique is reliable, but primarily under conditions that impose a high degree of situational constraint upon respondents. Implications of the results for door-to-door fundraising and for future research were discussed.     

Measuring Change in Motor Memory

Two points were made in support of the compression-block technique as a useful tool in motor-control research. The effect of motor impairment (if any) can be controlled (a) by only making direct comparisons between results obtained under block, and (b) by keeping muscle exertion during the entire course of the block to an absolute minimum to avoid muscle fatigue.     

Procedural learning across the lifespan: A systematic review with implications for atypical development

This systematic review aimed to investigate procedural learning across the lifespan in typical and atypical development. Procedural learning is essential for the development of everyday skills, including language and communication skills. Although procedural learning efficiency has been extensively studied, there is no consensus yet on potential procedural learning changes during development and ageing. Currently, three conflicting models regarding this trajectory exist: (1) a model of age invariance; (2a) a model with a peak in young adulthood; and (2b) a model with a plateau in childhood followed by a decline. The aims of this study were (1) to investigate this debate on procedural learning across the lifespan by systematically reviewing evidence for each model from studies using the serial reaction time task; and (2) to review procedural learning in autism spectrum disorder (ASD) and specific language impairment (SLI), two developmental disorders characterized by deficits in communication skills, in the light of these models. Our findings on typical development strongly support a model of age-related changes (Model 2a or 2b) and show that mixed findings regarding the developmental trajectory during childhood can be explained by methodological differences across studies. Applying these conclusions to systematic reviews of studies of ASD and SLI makes it clear that there is a strong need for the inclusion of multiple age groups in these clinical studies to model procedural learning in atypical development. Clinical implications of the findings are discussed. Future research should focus on the role of declarative learning in both typical and atypical development.     

Unicorn Atheism

Kripshe treats `god’ as an empty natural kind term such as `unicorn’. She applies Saul Kripke's fresh views about empty natural kinds to `god’. Metaphysically, says Kripshe, there are no possible worlds in which there are gods. Gods could not have existed, given that they do not actually exist and never did. Epistemologically, godlessness is an a posteriori discovery. Kripshe dismisses the gods in the same breath that she dismisses mermaids. Semantically, the perspective Kripshe finds most perspicacious, no counterfactual situation is properly describable as one in which there are gods. Perhaps it is not quite a necessary truth that there are no gods. According to Saul Kripke, failed natural kind terms are ill‐defined. Incorporating ill‐defined terms into declarative sentences yields only mock propositions. Just as the meteorologist has no professional interest in mock thunder, the logician has no professional interest in mock propositions. Kripshe disagrees with agnostics who assign a low probability to `There is at least one god’. The bearers of probabilities must be propositions. Despite this deference to science, Kripshe agrees with the a priori atheist that, necessarily, no future experience could constitute an encounter with a god. Divine revelation is impossible. Kripshe's a posteriori necessary atheism compares favorably to familiar forms of atheism and to non‐cognitivists. It reveals interesting challenges to a coherent formulation of atheism.
