The inter-domain among personality and cognition variables in people who commit murder

The inter-domain among personality (MMPI) and cognition (intelligence) variables in a sample of 137 males charged with first degree or capital murder was examined through canonical analysis. Race was included as a control variable. Two significant canonical correlations were found which contribute to an understanding of the relationship between personality and cognition in violent people. These variates were identified as Problem-solving Focus and Introspective Self-focus. Results also suggest that these inter-domain variates explain the relationship between personality and cognition variables to a greater degree for black murderers than for white murderers.     

The logic of causal methods in social science

Two kinds of causal inference rules which are widely used by social scientists are investigated. Two conceptions of causation also widely used are explicated — the INUS and probabilistic conceptions of causation. It is shown that the causal inference rules which link correlation, a kind of partial correlation, and a conception of causation areinvalid. It is concluded anew methodology is required for causal inference.     

Pronoun disambiguation: Accessing potential antecedents

Two general classes of pronoun disambiguation processes are considered. In reading “Jack threw a snowball at Phil, but he missed,” both possible antecedents of “he” (“Jack” and “Phil”) may be accessed initially. Or, the actual antecedent alone may be accessed after sufficient semantic context is encoded. To evaluate these alternatives, a yes-no-probe recognition task was used to measure priming of the potential antecedents in sentence comprehension. Subjects read sentences similar to the example and were presented a test word immediately following each sentence. Response times for the actual antecedent (“Jack”) and nonantecedent (“Phil”) probes were obtained. Results indicated that the nonantecedent as well as the antecedent was activated (accessed) in pronoun disambiguation. This conclusion was not affected by the ordering of the antecedent and nonantecedent in the first clause.     

Male responses to female competence

This study investigated the conditions under which a male would denigrate a female because of her competence. Sixty-four male subjects either cooperated or competed on anagram tasks with high/low competence male or female co-workers in the presence of a male or a female experimenter. Subsequently, these subjects evaluated their co-workers. No evidence was found to support the notion that males rejected a female partner because of her competence. In fact, some measures revealed that competent females were valued over their male counterparts in the cooperative conditions. Unexpectedly, sex of the experimenter interacted significantly with sex of the co-worker to determine the subject's responses to his partner's competence on two of the dependent measures. The discrepancies between these findings and earlier research findings are addressed. The implications for females in a mixed-sex work context are discussed.     

Late onset of alcoholism among older midwestern men in treatment

60 men were administered a questionnaire to assess whether the prevalence of alcoholism in men over 60 years of age in alcoholism treatment centers parallels the reported rates of late-onset for one-third or more alcoholics. Analysis showed 11% of the subjects were of late onset while 33% were quasilate onset. There were no significant differences in the life stress between alcoholics of early and later onset.     

Vocal changes in stutterers and nonstutterers when speaking to children

Within the last few years, considerable attention has been devoted to the possibility that the amelioration of stuttering in many novel speaking conditions is a function of vocal changes with or without accompanying modifications in prosodic expression. These formulations have made reference primarily to conditions in which stutterers were induced into one or another novel speech pattern by an external stimulus such as masking noise, a rhythmic cue, or by instructions to sing, or read in unison with another speaker. In contrast, far less attention has been paid to other ameliorative conditions that lack a novel external stimulus or special instructions that direct the stutterer to speak in some unique manner. Speaking or reading to a child is an example of this latter type of condition. The present study was conducted to see if nine adult stutterers and a matched group of nonstutterers would evince vocal changes as they read aloud to another adult, a child, and a child and adult together. There was also a fourth control condition wherein the subjects read to one of the experimenters. Dependent measures of disfluency and stuttering, fundamental frequency, fundamental frequency deviation, fluent reading rate, and peak vocal sound pressure level were made and treated statistically. The major findings of this study indicated that, relative to the control condition, both subject groups exhibited several vocal changes when reading to a child alone and to a child and adult together. In addition, the stutterers experienced a reduction in disfluency, but only when reading to the child alone. The normal speakers exhibited too few disfluencies in the control condition for any meaningful change to occur in that dependent variable. The fact that the stutterers evinced vocal changes in both experimental conditions but a significant drop in disfluency in just one bears importantly on hypotheses that emphasize vocal changes in conditions that ameliorate stuttering.     

Sexual experience, sex guilt, and sexual moral reasoning

Two studies are described in which the relations between sexual experience, sex guilt, and sexual moral reasoning were examined. Subjects were asked to articulate their opinions on each of six sexual activities, and then choose one of six statements (corresponding to Kohlberg's six stages of reasoning) that most clearly reflected why they had, or had not, engaged in three of those activities. An analysis of the moral reasoning present in each of the six articulated responses indicated that level of reasoning was inversely related to sex guilt. Analysis of the preference data indicated that subjects endorsed reasoning (statements) at a higher stage than they had articulated, and that this “gap” between articulation and preference was much greater for less experienced subjects. Results are discussed in terms of the utility of using situation-specific moral dilemmas when assessing moral reasoning, and in terms of the possible role that lack of sexual experience plays in inhibiting sexual moral development.     

Models of word recognition

Major hypotheses about the processes involved in word recognition are reviewed and then assessed through four experiments. The purpose of the first experiment was to examine some basic aspects of the processing of words, pseudowords, and nonwords, and beyond that, to discover basic differences in their processing that might underlie the word advantage. The second experiment was designed to assess the contribution of whole-word and letter cluster cues to the word advantage. Finally, Experiments III and IV were focused on the question of whether the word advantage can be wholly explained in terms of response bias or sophisticated guessing. Taken together, the results of these experiments were most compatible with criterion bias models. A version of the criterion bias model is suggested wherein the word advantage is attributed to interfacilitation among single letter and lexical units in memory.
