Stimulus motion and retrospective time judgments

The effect of stimulus motion on retrospective time judgments was investigated in four experiments. Subjects reproduced the duration of a 32-s interval which was filled by either a stationary or moving visual element presented on a computer monitor. In Experiments 1 and 4, the element moved horizontally back and forth, and in Experiments 2 and 3 it traced a circular pathway. In Experiments 1 and 2, the element moved at speeds of either 5 or 20 cm/s. In Experiment 3, it moved at a constant speed, alternating direction between clockwise and anti-clockwise rotation once every 1, 4, 8 or 16 s. In Experiment 4 the element moved at linear speeds of 1, 2, 4, 8 or 16 cm/s back and forth along a 16 cm horizontal path thereby alternating between left- and rightward motion-directions once every 16, 8, 4, 2 and 1 s, respectively. Temporal reproductions were not systematically influenced by stimulus speed. Rather, the pattern of results indicated a nonmonotonic relationship between remembered duration and the frequency of motion-direction changes; whereas remembered duration was unaffected by either infrequent or very frequent rates of changes, moderate rates of motion-changes lengthens remembered duration. These findings are discussed in relation to the change models of retrospective timing, and the claim that stimulus speed, as distinct from changes in the direction of stimulus motion, is not an important determinant of retrospective timing.     

Psychoanalytic patients in the U.S., CANADA,and Australia: I. DSM-III-R disorders,indications, previous treatment,medications, and length of treatment

To determine the demographics, DSM-III-R disorders diagnosed, indications used in recommending psychoanalysis, previous treatment histories, use of medication, and length of treatment in patients in psychoanalysis in the U.S., Canada, and Australia, a mail survey of practice was sent to every other active member of the American Psychoanalytic Association and every member of the Australian Psychoanalytical Society. This supplemented an earlier survey sent to all Ontario psychoanalysts. The response rates were 40.1 % (n = 342) for the U.S., 67.2% (n = 117) for Canada, and 73.9% (n = 51) for Australia. Respondents supplied data on 1,718 patients. The employment rate for patients increases as analysis progresses (p < .0001). The mean number of concurrent categories of disorders (Axis I, Axis II, and Disorders First Evident in Childhood) per patient at the start of treatment is 5.01 (SD = 3.66; median = 4; mode = 3). There are no statistically significant differences across countries. Mood, anxiety, sexual dysfunction, and personality disorders are most common. American Psychiatric Association / American Psychoanalytic Association peer review criteria for indicating psychoanalysis are followed for 86.5% of patients. Over 80% of patients in all three countries had undergone previous treatments prior to analysis. In the U.S., 18.2% of analysands are on concurrent psychoactive medication; in Australia, 9.6%. The mean length of analyses conducted in the U.S. is 5.7 years, in Australia 6.6, and in Canada 4.8. Psychoanalytic patients in all three countries have similar rates of DSM-III-R psychopathology, and many indications of chronicity.     

Chinese adolescents' explanations of poverty: the Perceived Causes of Poverty Scale

The Chinese Perceived Causes of Poverty Scale (CPCPS), constructed to assess how Chinese people explain poverty, covers four categories of explanations: personal problems of poor people, lack of opportunities to escape from the poverty cycle, exploitation of poor people, and bad fate. Chinese secondary school students (N = 1,519) were administered the CPCPS. Four factors were abstracted from their responses (Personal Problems, Lack of Opportunity, Exploitation, and Fate) and these factors (i.e., subscales) could reliably be reproduced in different subsamples. The four subscales were also found to be internally consistent and there was some support for their construct validity.     

Social neuroscience: understanding the pieces fosters understanding the whole and vice versa

Social science and neuroscience perspectives represent two ends of a continuum of levels of organization studied in psychology. Human behavior as a whole unfolds at social levels of organization, whereas much of the research in psychology has focused on cognitive and biological pieces of this whole. Recent evidence underscores the complementary nature of social, cognitive, and biological levels of analysis and how research integrating these levels can foster more comprehensive theories of the mechanisms underlying complex behavior and the mind. This research underscores the unity of psychology and the importance of retaining multilevel integrative research that spans molar and molecular levels of analysis.     

Encouraging research: make it collegial,enjoyable, and relevant

Researchers are too often trained under circumstances that discourage them from continuing research activities after they graduate. Three hypotheses are suggested that, if confirmed, would lead to a greater number of competent and enthusiastic researchers. (a) Arrange compatible peer groups. Allowing graduate students to form research teams to conduct dissertation studies would provide more social support than the individualistic environment traditionally required does. (b) Make the experience satisfying and enjoyable. Infuse a spirit of playfulness and puzzlement.
