Brain damage,diagnosis, and substance abuse among violent offenders

Neuropsychological functioning, diagnoses, and substance abuse were compared among killers, nonhomicidal assaulters, and nonviolent offender controls. The Reitan and Luria-Nebraska Neuropsychological test batteries, the WAIS-R, CT scans, and EEGs were examined with a trend to more neuropathology found in killers and assaulters than in controls. There were no group differences in ICD-9 diagnosis nor on the MMPI, although considerable personality pathology was noted in all groups. Violent offenders scored higher on the Michigan Alcoholism Screening Test (MAST). The violent offenders were more likely to experience alcohol and drug-related mood dysphoria. The interaction of neuropsychological, personality, and substance abuse variables is discussed.     

Sex hormones in murderers and assaulters

A study of hormonal levels of violent and nonviolent offenders failed to establish any significant differences among murderers, assaulters, and controls. While the results do not suggest a contributory role for random blood hormone levels in facilitating aggressive behavior, further study of complex interactions is necessary to rule out endocrinological factors.     

Dates of entry and measures of imagery,concreteness, goodness,and familiarity for 1,046 words sampled from theOxford English Dictionary

TheOxford English Dictionary is the standard reference work for determining the earliest known instance of the occurrence of a word (its date of entry). Partly in order to facilitate research on the relation between the date of entry and other psychological variables, we gathered normative data on 1,046 words sampled from theOxford English Dictionary. We present data for scales that measure the imagery, concreteness, goodness, and familiarity values for words. These norms may also be of use to researchers who are not explicitly concerned with words’ date of entry, but who wish to sample words from a set that contains a large number of unfamiliar as well as familiar words.     

Psychometric properties of the children's atypical development scale

The Children's Atypical Development Scale (CADS) is a 53-item rating scale designed to measure unusual behaviors in children. Principal-factor analysis on a clinic-referred and pediatric sample of 474 children resulted in a four-factor solution: Communication Deficits, Lability, Social Relatedness Deficits, and Preoccupation. The CADS is internally consistent and has adequate temporal stability. CADS factor scores were differentially associated with parent and teacher rating scales, IQ, and Continuous Performance Test errors. The scale shows promise as a clinical and research tool for assessing atypical behaviors associated with pervasive developmental disorder and other neurobehavioral disorders.This research was supported in part by a grant from the Smart Family Foundation.

Semantic indeterminacy and the realist stance

Semantic Indeterminacy and Scientific Realism are perhaps the two most ubiquitous and influential doctrines of the Quinean corpus. My concern is to argue against neither in isolation, but against their joint compatibility. Scientific Realism, I argue, when understood as Quine's realistic attitude toward the posits of physical theory, is essentially intentional in character. Thus, Realism requires Intentionality. In Section 1, I provide some necessary exegesis. In Section 2, I attempt to show how this Realism/Intentionality connection arises, surprisingly, within Quine's own mature work to create a tension in his views which he does not himself resolve. In Section 3, I examine the source of the Realism/Intentionality connection more deeply, and respond to possible Quinean objections to my account. In Section 4, I consider the consequences of the connection for various debates in recent analytic philosophy.     

A Microcomputer Assessment System (MAS) for administering computer-based surveys: Preliminary results from administration to clients at an impaired-driver treatment program

The Microcomputer Assessment System (MAS), written in C language, allows a researcher to design and administer computer-based surveys by manipulating ASCII text files and requires no knowledge of a traditional programming language. The system was designed to provide maximum user flexibility: MAS allows both multiple-choice and open-ended (fill-in) questions and allows control over text color, allowable answers, and summary output. MAS also assesses response latency and includes support for random assignment of different instruments to respondents. MAS runs under MS-DOS 3.0 or higher, requires 640K of RAM, a color screen (EGA or better), and an extended keyboard. Preliminary results from an application of MAS to a sample of. 121 clients at an impaired-driver treatment program are summarized.     

Using HyperCard and Apple events in a network environment: Collecting data from simultaneous experimental sessions

HyperCard is a useful tool available to teachers and researchers who have access to Macintosh computers. Version 2.1 of HyperCard, in conjunction with the Macintosh Operating System 7, includes some significant new capabilities for users with multiple computers in a network, as is common in many teaching laboratories. This paper describes a HyperCard stack that allows users who wish to run HyperCard-based experiments on several computers simultaneously to conveniently retrieve experimental data from those remote computers onto one program, and to perform several other useful tasks in a computer network.     

USING TIME DELAY TO PROMOTE SPONTANEOUS SPEECH IN AN AUTISTIC CHILD

One of the frequently observed deficits in autistic children is their lack of spontaneous speech. We used a multiple baseline across behaviors to investigate the effectiveness of a time delay procedure for inducing spontaneous speech in a 10-year-old male autistic child during play. We first taught the child to imitate the experimenter's verbal prompts that described the child's motor response. Once the child reached criteria on imitation, we implemented baseline wherein an immediate verbal prompt for speech was provided after each of the child's motor responses. Intervention consisted of a gradual delay in the presentation of the verbal prompts. The time delay effectively increased the child's spontaneous speech on trained items; some generalization to untrained items also occurred, but only within the same behavioral class of car play. Generalization was also observed across settings. Spontaneous speech remained at high levels during the 4-month maintenance for the behavior of car play but decreased for a second behavior. Decreases in the child's response latencies suggest that spontaneous speech may be an anticipatory verbal response.
