An intelligent PET interface for environmental control and data acquisition and analysis

An interface, controlled by a Z-80 central processor, that plugs into the PET microcomputer’s IEEE-488 port is described. This interface is capable of controlling 48 separate 28-V dc output signals, six of which are high current. Sixteen inputs (switch closures) can be accepted by the interface. Data tagged with real-time information are output automatically to cassette tape in PET format. This PET interface system is designed to accommodate a single experimental station.     

Berlyne's theoretical contributions to psychology

The evolutions of Berlyne's theoretical contributions are traced by contrasting his particular developments with seven characteristics of Hullian theory. Berlyne is seen to have dismantled each element and replaced it with a vastly different theoretical position and structure. Berlyne developed a truly general theory, which was then differentiated with special concepts in specific areas as diverse as thinking and aesthetics.Much of the content of this article first appeared in Walker (1961).

Advancing Creativity Theory and Research: A Socio-cultural Manifesto

This manifesto, discussed by 20 scholars, representing diverse lines of creativity research, marks a conceptual shift within the field. Socio-cultural approaches have made substantial contributions to the concept of creativity over recent decades and today can provide a set of propositions to guide our understanding of past research and to generate new directions of inquiry and practice. These propositions are urgently needed in response to the transition from the Information Society to the Post-Information Society. Through the propositions outlined here, we aim to build common ground and invite the community of creativity researchers and practitioners to reflect up, study, and cultivate creativity as a socio-cultural phenomenon.     

National-level Indicators of Androgens are Related to the Global Distribution of Scientific Productivity and Science Nobel Prizes

There are national differences in scientific activity that are not well accounted for by economic and intellectual factors alone. We examine the novel hypothesis that androgen levels may also play a role. Androgens are often referred to as male hormones, but are present in both men and women, and have been linked to performance in other domains, such as sports and entrepreneurship. National-level empirical data on scientific productivity, in terms of numbers of publications, and science Nobel laureates were compared to seven national-level androgen indicators; namely androgenic body hair, the length of the CAG repeat on the androgen receptor gene, prostate cancer incidence, male and female 2D:4D finger ratio, and sex frequency and number of partners. The majority of these indicators were associated in the expected direction with per capita number of scientific publications and Nobel prizes. Moreover, several indicators significantly interacted with national-level estimates of intelligence, such that androgen levels are related to measures of the scientific achievement only when the level of intelligence is relatively high. These findings may partly explain the global distribution of scientific productivity, achievements, and Nobel prizes.     

Neonatal functioning and the sudden infant death syndrome

A male infant, diagnosed as a Sudden Infant Death Syndrome (SIDS) at 5 months, 3 weeks, had been extensively tested as a part of a larger sample in a longitudinal study. The longitudinal sample was comprised of 137 clinically normal neonates, born to intact upper middle-class families, living in a large metropolitan area. A neonatal assessment consisted of 5 hours of polygraphic recordings of heart and respiratory rate during sleep and waking cycles, and 1 hour of behavioral testing. At 3 months of age the infant was observed for 12 hours in the home. Retrospective analyses of these data suggested that: (a) neonatal respiratory behavior during sleep did not distinguish this infant from a sample of control infants; (b) the infant lacked strength in movements requiring the involvement of shoulder and neck muscles (head lift from a prone position); and (c) informal observations by skilled and experienced observers distinguished this infant from the sample of controls.

Performance of pigeons on delayed simple and conditional discriminations under equivalent training procedures

A pair of experiments investigated the short-term memory of pigeons under delayed simple and conditional discriminations. Trial sequences in both discriminations consisted of a color as the sample stimulus, a memory interval, a line orientation as the test stimulus, and a trial outcome, which was either food reinforcement or blackout. Pecking rates during the test stimulus defined discrimination performance. In the simple discrimination, the sample provided the necessary information regarding the subsequent trial outcome. In the conditional discrimination, the sample and test stimuli conjointly provided this information. In Experiment 1, the two procedures were compared with independent groups of pigeons. In Experiment 2, the comparison was made within subjects. The simple discrimination was acquired more quickly and was performed better with a memory requirement. Introduction of long delays disrupted performance even at shorter delays in both discriminations. Postulation of prospective as well as retrospective mediating processes facilitates the interpretation of these results.     

ELIMINATION OF ECHOLALIC RESPONDING TO QUESTIONS THROUGH THE TRAINING OF A GENERALIZED VERBAL RESPONSE

Echolalia, the parroting of the speech of others, is a severe communication disorder frequently associated with childhood schizophrenia and mental retardation. Two echolalic children, one schizophrenic and one retarded, were treated in a multiple-baseline design across subjects. Each child was taught to make an appropriate, nonecholalic verbal response (i.e., “I don't know”) to a small set of previously echoed questions. After such training, this response generalized across a broad set of untrained questions that had formerly been echoed. The results obtained were the same irrespective of the specific experimenter who presented the questions. Further, each child discriminated appropriately between those questions that had previously been echoed and those that had not. Followup probes showed that treatment gains were maintained one month later. The procedure is economical, in that it produces a rapid and widespread cessation of echolalic responding.
