Five rated characteristics of 650 word association stimuli

Abstract: Ratings are presented for 650 stimuli from word-association lists on each of five scales: good—bad, pleasant—unpleasant, emotional—neutral, concrete—abstract, and easy to associate to—difficult to associate to. The ratings are shown to be highly reliable, and to agree well with previously collected norms of a similar character. The intercorrelations of the five scales with one another and with word frequency are reported.

Aromatic Character and Aromaticity

Abstract: This book, first published in 1969, analyses the special properties of benzene and its derivatives, which give them their distinct aromatic character.

Orientation of letters and errors in their recognition

Abstract: Subjects named alphabetic characters that had been rotated, reflected, or inverted. Inversions induce more errors than mirror reflections and reflections induce more than rotations. In a significant number of mistakes a transformed character was assumed to be normally oriented, but in most a transformed character was confused with the mirror image of the original. The data suggest the existence of an “orientation set” in which the identiflcation of ambiguous characters depends largely on their anticipated orientation. The individuality of the data for the different orientations suggests that different transformations are compensated for in part by different mechanisms.

Character recognition circuitry

Abstract: This invention is directed to method and apparatus for the reading and identification of characters on business documents and the like. Analog wave forms derived from scanning the characters are analyzed by integrating the signals in a plurality of time zones or divisions which span the width of the character. The integrated signals are then supplied to a plurality of correlation networks, one for each character to be recognized. The network having the highest output, as determined by maximum level detector means, represents the character which has been scanned.

Finite Linear Groups of Degree Seven. I

Abstract: 1. 1. This paper is the second in a series of papers discussing linear groups of prime degree, the first being (8). In this paper we discuss only linear groups of degree 7. Thus, G is a finite group with a faithful irreducible complex representation Xof degree 7 which is unimodular and primitive. The character of Xis x- The notation of (8) is used except here p= 7. Thus Pis a 7-Sylow group of G.In §§ 2 and 3 some general theorems about the 3-Sylow group and 5-Sylow group are given. In § 4 the statement of the results when Ghas a non-abelian 7-Sylow group is given. This corresponds to the case |P| =73 or |P|= 74. The proof is given in §§ 5 and 6. In a subsequent paper the results when Pis abelian will be given.

Method and apparatus for style and specimen identification

Abstract: The character recognition system identifies characters in each of three different fonts. Each character is scanned to obtain a binary word representation of the character. This representation is applied to three tables storing probability representations for each known character in the three fonts. Character comparison functions for each character in each font are produced which are stored in a buffer for later character identification and are also applied to three accumulators to provide three font comparison functions for the unknown character. From these functions the font is determined without, at that time, identifying the character. The results of a series of font identifications for a sequence of unknown characters are stored on a current basis, and from these results, font frequency functions are derived which are then employed to modify the character comparison functions that have been stored in the buffer. The modified character comparison functions are compared to identify the unknown character.

Bayes Sequential Designs of Fixed Size Samples from Finite Populations

Abstract: The problem of choosing a sample of a fixed size from a finite population is studied in the framework of Bayes designs. The conjectured non-randomized character of Bayes designs is verified. Bayes designs are shown to be without replacement selections, which are generally sequential ones. Sufficient conditions are provided for the optimality of single-phase designs. An example is provided of a case in which the optimal Bayes design is sequential.

Character display system

Abstract: A system responsive to incoming electrical digital signals representing alpha-numeric characters and supplied in series character format at a varying rate. The system is adapted to display these characters in the form of dot matrices and to move such displayed characters in a video line across the face of a cathode-ray tube. The rate of character movement is varied in accordance with changes in the rate at which the signals are supplied to the system to eliminate visually apparent changes in the speed of movement of the displayed characters.

Individual thinking and family interaction. IV. A study of information exchange in families of normals, those with character disorders, and schizophrenics.

Abstract: This was the third of three experiments designed to study the reciprocal relationship between family interaction and individual thinking. The present experiment was developed to test a family's efficiency in exchanging information within itself. In particular, it tested how well members utilized minimal cues about the informational needs of others in their family. We studied families of normals, those with character disorders, and schizophrenics, five families in each group. On the basis of previous experiments we expected families of normals and schizophrenics to be highly sensitive to cues from within the family. We expected both groups to exchange information efficiently by elaborating ways of ordering messages using only subtle cues that could convey each member's informational needs. The findings, in general, confirmed the expectations. Taking these with the results of the first experiment, we suggested that our families of schizophrenics appeared to represent a group of families who effectively utilize cues from within but not without the family. This may lead them to overvalue ideas and opinions of family members and undervalue cues from the external environment in their collaborative solutions of externally given problems.

Character recognition systems

Abstract: A character recognition system, in which the outputs of individual photocells of a matrix are grouped together, is disclosed, Each group of outputs is applied through a detector to produce a group of binary signals which signals are applied as an input to an encoding device. Each encoding device has an output for each possible input signal from an associated group of photocell outputs, each encoding device output being connected to access a different location in a store. Each photocell group output accesses a different store location, a weighting function being stored in each store location. The weighting functions of sets of store locations in a set are summed and compared with the sums of other sets of store locations in order to identify an unknown character displayed to the photocell matrix.

Character recognition using mask integrating recognition logic

Abstract: A graphic character is scanned and entered in a shift register. Combinatorial-logic masks detect respective video features from the shift register. Pulses from each mask advance separate counters. In a later decision cycle, a number of artificial pulses advance all counters simultaneously. When the first counter overflows, a number of further artificial pulses advance all counters. If one and only one counter overflows, the character is recognized; otherwise, the character is rejected. Either set of artificial pulses may be made variable.

An optical character recognition arrangement

Abstract: Process of optical character recognition for different sizes of character, in which the characters are scanned in columns, stored in a shift register, removed therefrom in rows and the bit combinations are associated with outlets in a ''''probe'''' network. Then the bit combination, thus determined, of the character to be recognized is compared with the bit combinations of all of the stored compare characters simultaneously taking into account the location of the character in the character area, and the number of agreements is determined. The greatest number of agreements determines the character.

Data storage and display system

Abstract: A data storage and display system is provided with a control feature for selectively displaying stored message formats having fields into which data is to be entered by an operator. The feature includes means for insuring that the data entered into each field is of the numeric or alphabetic type if either has been specified on a character-by-character basis. If the operator attempts to enter any other type of character for a given specified character, an error is indicated and a correct character must be entered before proceeding to the next character in the same or different field. There is also provision for determining whether entries in all fields have been completed before the message format can be transferred to a file storage and control unit.
