Channel selection and the suffix effect

Subjects were presented with a list of digits to alternate ears for serial recall. The list was followed by a suffix, a redundant acoustic event which did not have to be recalled. The suffix was presented either to one of the ears or binaurally. In all cases the suffix gave rise to a selective impairment of recall of the final items in the list. The results are interpreted as showing first that stimuli of the kind used are processed by simultaneously selecting both ears rather than by switching attention, and second that the site of the suffix effect is after the selection mechanism.     

Modeling: An analysis in terms of category accessibility

It is proposed that many of the releasing or disinhibiting effects caused by models can be accounted for by information-processing mechanisms, without recourse to the concept of reinforcement. More specifically, it is suggested that the process of viewing a model's behavior involves the activation of an interpretive schema. This renders the information the schema incorporates more accessible for subsequent use. If the schema incorporates (or is closely related to) behavior-specifying information, that information becomes more accessible as well, thus making it more likely to influence overt behavior. Two studies are reported that assessed the plausibility of this reasoning. In Experiment 1 subjects who had viewed an aggressive model perceived greater hostility in the behavior of an ambiguous stimulus person that they subsequently encountered than did control subjects. This finding is consistent with the assumption that the model's behavior activated a conceptual schema for use in interpretation. In Experiment 2 subjects in whom an aggressive schema had been activated under a guise displayed greater aggression in their subsequent behavior in a different context than did control subjects. This finding is consistent with the assumption that activating the conceptual schema also activated behavioral information. The discussion centers on the implications of the findings.     

CASPER: A personal computer package for exploring psychometrics

CASPER is a psychometrics software package suitable for instructional and research applications with IBM-PC-compatible computers. CASPER lets the user simulate or directly enter psychometric data. Numerous statistical analyses, file handling procedures, and graphics are included Analyses include factor analysis, multiple regression, correlation/partial correlation, moments analysis, reliability analysis, and item analysis.     

Lateral masking as a function of spacing

It is argued that lateral masking is a composite of several processes. These processes include response competition, distribution of attention, perceptual grouping, and feature (contour) interaction. Three experiments were carried out in an attempt to isolate some of the components. In the first two experiments, it was shown that feature interaction dominates at close spacing but other processes dominate at wider spacing. The third experiment showed that at least part of the effect of perceptual grouping appears to be information provided about target location.     

An exploration of prevalence of domestic violence in same-sex relationships

The prevalence of domestic violence in a sample of 33 men and 33 women currently or previously in same-sex relationships was assessed. Data were collected through a mail survey in the state of Virginia. Of 1000 surveys sent out 66 usable ones were returned (response rate = 6.6%). Analysis indicated that 34 had experienced some form of domestic violence, but significant differences between male and female respondents were not detected. When data from this same-sex sample were compared with those of the heterosexual sample of the National Violence Against Women Survey, intimate partner assault may be more prevalent against gay men than against heterosexual men, but there was no significant difference between lesbians and heterosexual females.     

Assessing male batterers with the Personality Assessment Inventory

In this study, we sought to provide empirical data on the utility of the Personality Assessment Inventory (PAI; Morey, 1991) for the assessment of male batterers. The sample consisted of 93 men who were court mandated to treatment. In the study, we were able to replicate 2 of 3 clusters (borderline/dysphoric and nonelevated) commonly found in the literature on male batterers; however, we only partially replicated the 3rd cluster (antisocial/narcissistic). This new finding may reflect a difference in the assessment instrument used to assess male batterers (i.e., PAI). In this study, we also investigated a previously understudied subgroup of batterers, specifically, men who engage in positive impression management. In this study, we conclude that the PAI is a potentially useful instrument in assessing male batterers and provide suggestions for future research.     

Knowing too much: using private knowledge to predict how one is viewed by others

People have more information about themselves than others do, and this fundamental asymmetry can help to explain why individuals have difficulty accurately intuiting how they appear to other people. Determining how one appears to observers requires one to utilize public information that is available to observers, but to disregard private information that they do not possess. We report a series of experiments, however, showing that people utilize privately known information about their own past performance (Experiments 1 and 2), the performance of other people (Experiment 3), and imaginary performance (Experiment 4) when intuiting how they are viewed by others. This tendency can help explain why people's beliefs about how they are judged by others often diverge from how they are actually judged.     

A cybernetic theory of morality and moral autonomy

Human morality may be thought of as a negative feedback control system in which moral rules are reference values, and moral disapproval, blame, and punishment are forms of negative feedback given for violations of the moral rules. In such a system, if moral agents held each other accountable, moral norms would be enforced effectively. However, even a properly functioning social negative feedback system could not explain acts in which individual agents uphold moral rules in the face of contrary social pressure. Dr. Frances Kelsey, who withheld FDA approval for thalidomide against intense social pressure, is an example of the degree of individual moral autonomy possible in a hostile environment. Such extreme moral autonomy is possible only if there is internal, psychological negative feedback, in addition to external, social feedback. Such a cybernetic model of morality and moral autonomy is consistent with certain aspects of classical ethical theories.
