|
| Familiar arrays of objects are perceived better than novel arrays, indicating a perceptual bias toward expected inputs. Yet a novel object in an otherwise familiar array attracts attention, indicating a perceptual bias toward unexpected inputs. These phenomena describe a highly adaptive system but pose a paradox: How can the mind be biased simultaneously toward both what it most expects and what it least expects? Our research on novel popout illuminates ... |

|
| Perceptual memory refers to experience-induced changes in perceptual processing of particular objects or scenes. Part 1 of this report summarizes the results of 8 studies of the role of perceptual memory in recognition memory. The hypothesis was confirmed that perceptual memory-contributes to the feeling of familiarity that observers sometimes experience even when they lack explicit memory for previously encountered objects. Part 2 summarizes the results of 14 studies of a ... |

|
| Observers who glimpsed 4-word arrays were probed for the locations of particular words. Some words, called 'familiar', appeared in many arrays; and others, called 'novel', appeared in only one. Studies conducted in the first year showed that familiar words are more localizable than novel words when they are not mixed together in the same array but that this difference is diminished, and often reversed, when a single novel word is ... |

|
 | In several experiments, observers were given glimpses of 4-word arrays. Accuracy of word location was tested after each array. Some words, called familiar, appeared many times across the series of arrays; others, called novel, appeared only once. The ratio of novel to familiar words in an array ranged from 0:4 to 4:0. When familiar and novel words were not intermixed (in 0:4 to 4:0 arrays), localization accuracy was higher for ... |

|
| Air Force recruits (N = 513) viewed a long series of briefly presented, 4-word arrays. After each array, subjects received one of the four words as a probe and were asked to indicate the array location in which that word had appeared. Subjects were encouraged to distribute their attention evenly across array locations in a divided-attention condition. Different arrays presented different mixtures of novel (never repeated) and familiar (often repeated) ... |

|
| Attempts to block withdrawal seizures, in animals addicted to barbiturates with meprobamate, librium, chloral hydrate, 1-dopa, and various combinations of these drugs were without success. The reasons for the failure of these drugs to block withdrawal symptoms were discussed. (Author) |

| An Analysis of Factors Influencing Alcohol Consumption of Alcoholic Rats. |

|
| Evidence is presented that stress is not a factor that is directly involved in the alcohol consumption of rats, whether the stress was from shock or coping behavior. Two methods are described of producing physical dependence in rats, one to alcohol and the second to phenobarbital. Physical dependence upon alcohol was established in rats by housing them in activity wheels and feeding them, ad lib, a liquid diet in which ... |

|
| The effects of librium, meprobamate, chloral hydrate, pentobarbital, paraldehyde and ethanol upon brain thresholds is detailed. In addition, the sequence of changes of the reticular formation and the caudate nucleus during the acquisition of physical dependence to pentobarbital, and also during withdrawal from pentobarbital is described. It was hypothesized that the development of drug dependence is characterized by a double dissociation, the peripheral nervous system from the central nervous system ... |

|
| Seven experiments are reported which are part of a research project to understand factors that influence alcohol consumption of rats and to develop techniques that will make the rat the counterpart of the human alcoholic. In the first two experiments investigated the role that taste and caloric stress play in influencing alcohol consumption of rats. The rats in these experiments were individually housed in activity wheels, placed on 23.5-hour feeding ... |

|
| Cats have been trained to give conditioned avoidance responses with direct electrical stimulation of the brain as the conditioned stimulus. After these conditioned responses were established the brain excitability levels, as measured by the intensity of brain stimulation necessary to maintain those conditioned responses, were determined. The effects of various dosages of paraldehyde, meprobamate, chloral hydrate, and chlordiazepoxide, upon brain excitability levels was determined for cats trained in the normal, ... |

|
| The study extends and explores in depth factors that began to be discovered during research reported in 1958 (AD-151 043). Three batteries of scores, called A, B, and C, are analyzed. Battery A includes only aptitude test scores. Battery B contains some of the aptitude test scores and many personality and other self-report scores. Battery C contains 57 predictor scores and 27 situational criterion scores. 'Communication abilities' are interpreted as ... |

| An Evaluation of Some Performance Test Scores Used in Electronic Troubleshooting Research. |

| Authors:
Oliver Keith Hansen; UTAH UNIV SALT LAKE CITY DEPT OF PSYCHOLOGY
|
| Much of the early work on electronic troubleshooting concerned performance on relatively simple equipment. For various reasons researchers have been reluctant to draw upon findings of simple-equipment studies for explanation of performance on complex equipment. The study upon which this report is based represented an initial attempt at an empirical exploration of troubleshooting performance on highly complex equipment. The study aimed at the development and evaluation of K-system troubleshooting performance ... |
