Less is more: the lure of ambiguity, or why familiarity breeds contempt

The present research shows that although people believe that learning more about others leads to greater liking, more information about others leads, on average, to less liking. Thus, ambiguity--lacking information about another--leads to liking, whereas familiarity--acquiring more information--can breed contempt. This "less is more" effect is due to the cascading nature of dissimilarity: Once evidence of dissimilarity is encountered, subsequent information is more likely to be interpreted as further evidence of dissimilarity, leading to decreased liking. The authors document the negative relationship between knowledge and liking in laboratory studies and with pre- and postdate data from online daters, while showing the mediating role of dissimilarity.     

Internal clock processes and the filled-duration illusion

In 3 experiments, the authors compared duration judgments of filled stimuli (tones) with unfilled ones (intervals defined by clicks or gaps in tones). Temporal generalization procedures (Experiment 1) and verbal estimation procedures (Experiments 2 and 3) all showed that subjective durations of the tones were considerably longer than those of unfilled intervals defined either by clicks or gaps, with the unfilled intervals being judged as approximately 55%-65% of the duration of the filled ones when real duration was the same. Analyses derived from the pacemaker-switch-accumulator clock model incorporated into scalar timing theory suggested that the filled/unfilled difference in mean estimates was due to higher pacemaker speed in the former case, although conclusively ruling out alternative interpretations in terms of attention remains difficult.     

Cognitive decline and human (Homo sapiens) aging: an investigation using a comparative neuropsychological approach

Using a comparative neuropsychological approach, the authors compared performance of younger and healthy older adults ages 65 and over on tasks originally developed to measure cognition in animals. A battery of 6 tasks was used to evaluate object discrimination, egocentric spatial abilities, visual and spatial working memory, and response shifting. Older adults performed more poorly than younger adults on tasks that evaluate egocentric spatial abilities, response shifting, and to a lesser extent object recognition. The two groups did not differ for tasks that evaluate spatial working memory and object discrimination. The impairments the authors observed in tasks that evaluate response shifting and object recognition are consistent with those found in canines and primates as well as those found in Alzheimer's disease. The results are consistent with the notion that cognitive processes supported by the amygdala and the orbitofrontal cortex are among the first to decline with increasing age in both humans and animals.     

What Is A Newtonian System? The Failure Of Energy Conservation And Determinism In Supertasks

Supertasks recently discussed in the literature purport to display a failure ofenergy conservation and determinism in Newtonian mechanics. We debatewhether these supertasks are admissible as Newtonian systems, with Earmanand Norton defending the affirmative and Alper and Bridger the negative.     

Developing Multicultural Counseling Competence Through the Use of Portfolios

This investigation tested the ability of portfolios to stimulate the acquisition of multicultural counseling competence within counselors‐in‐training and compared portfolios with another method of competence development, case formulation. Results indicate that portfolios benefit the acquisition of multicultural counseling competence. Implications for training in multicultural counseling competence are discussed. Esta investigación probó la habilidad de portafolios para estimular la adquisición de competencia de terapia multicultural dentro de consejeros en instrucción y portafolios comparadas a otro método del desarrollo de la competencia, la formulación del caso. Los resultados indican que los portafolios benefician la adquisición de la competencia de terapia multicultural. Las implicaciones para entrenar en la competencia de terapia multicultural se discute.     

Memory for event frequency as a function of depression, age, intentionality, and level of processing

In two experiments, we examined memory for event frequency among depressed and/or elderly subjects (depression was either naturally occurring or induced by the Velten technique). We also manipulated level of processing and instructional set to test the notion that memory for event frequency is relatively invariant across a variety of tasks. Results supported the proposal that memory for frequency is robust in the face of depression and old age. Memory for frequency was enhanced, however, by semantic processing and by an intentional learning instructional set. Finally, the results suggest that the Velten technique not only induced variation in mood but also may have induced a semantic processing strategy in our depressed and elated subjects.     

Full-time studying and long-term relationships: Make or break for mature students?

Results are reported of a 2-year longitudinal study looking at the effects of full-time degree study on full-time mature students who were also in long-term committed relationships. The findings from the first year of the research suggested that while there were particular stresses for students with domestic responsibilities; the single most buffering effect was support from the student's partner. The follow-up study in the second year confirmed these findings, but also suggested that there was a decrease in the amount of partner support experienced in the second year. The implications for counselling and student support services are discussed.     

Formation of food aversions in cancer patients receiving repeated infusions of chemotherapy

Patients receiving emetogenic chemotherapy for cancer have been found to develop aversions to normal dietary items consumed in close temporal relation to treatment administrations. These aversions are presumed to develop via conditioning processes as demonstrated in experimental studies of food aversion learning. The present study used a prospective, longitudinal design to evaluate the possible role of conditioning in the formation of aversions to normal dietary items in women receiving adjuvant chemotherapy for breast cancer. Patients were monitored for the development of aversions to foods and beverages consumed in the 24 hr periods before and after each of eight consecutive chemotherapy infusions beginning with the initial infusion. Data on the prevalence, course, and prediction of aversions to normal dietary items are reported. These results pointed to similarities and differences between aversions formed to normal dietary items during chemotherapy treatment and aversions formed to taste stimuli during experimental conditioning studies. In addition to their theoretical significance, results also suggest possible strategies for preventing the clinical problem of aversions to normal dietary items in chemotherapy patients.
