Expert Testimony and Sexual Predator Statutes after Hendricks

The recent decision of the United States Supreme Court in Kansas v. Hendricks (1997) upheld a sexual predator statute that authorizes civil commitment of certain sex offenders who have been convicted of sexual offenses and have served criminal sentences for those offenses. This case raises a variety of Constitutional questions in the United States, but it also raises a series of interesting questions about the appropriate scope of expert testimony by psychologists regarding commitments under these statutes. These issues regarding expert testimony are significant both in their own right and because addressing them confronts one with serious difficulties regarding the normative foundations of the statutes. This paper examines the significance of the Court's brief substantive due process analysis for the role of psychological expert testimony regarding commitment under these statutes, and it identifies but does not attempt to resolve the associated normative concerns regarding the justification for commitment under these statutes.     

Developing community alternatives to group home placement for SED special education students in the Ventura County System of Care

Interagency planning and resource development were used to improve available services for severely emotionally disturbed special education students who were in or at-risk of being placed in residential care. Augmented local school-based and regional day treatment services were financed by a Ventura County Social Services Agency trust fund and delivered cooperatively by the County Mental Health Agency and local education agencies. Revenues generated by the new service positions were planned to restore the trust fund. Outcomes following service implementation included: (a) an average reduction of 3.5 youths in the expected number of youths in group home placement per month; (b) a total reduction of $290,011 in the expected annual cost of placement; and (c) generation of $281,238 in Medi-Cal revenue by the school-based and day treatment components of the system of care. The implications of these outcomes are discussed in terms of existing trends in numbers of identified seriously emotionally disturbed students and their service needs and the processes that were involved in planning and implementing the service augmentation.     

Perceived probability and evaluation of balance,agreement, and attraction: Toward a solution of conflicting results

Fifty-four subjects rated sixteen hypothetical situations on four evaluative and four probability scales. The situations were of the P-O-X type, consisting of two persons and an issue. A2×2×2×2 factorial design was used to test the relative importance of attitude (P to × relation), issue (marijuana or premarital sex), agreement (P to × and O to × relations), attraction (P to O relation), and balance (agreement × attraction interaction) on the evaluation and probability variables. As predicted from a critical review of past research on balance theory, balance was the main determinant of perceived probability. Attraction was the main determinant of evalution. In light of a review of past balance research and of the present data, we propose to restrict the balance hypothesis to cognitive variables, i.e., expectancy and perceived probability. In addition, support was obtained for the hypothesis that the more dogmatic a person is, the more frequently he will perceive balanced relationships as occurring and the more positively he will evaluate balanced situations.     

When smiles (and frowns) speak words: Does power impact the correspondence between self-reported affect and facial expressions?

Self-reported experiences are often poor indicators of outward expressions. Here we examine social power as a variable that may impact the relationship between self-reported affect and facial expressions. Earlier studies addressing this issue were limited by focusing on a single facial expression (smiling) and by using different, less sensitive methods that yielded mostly null results. Sampling, for the first time, self-reported affect repeatedly in response to different negative, neutral and positive stimuli, and measuring concurrent facial muscle activation via electromyography, we found that high power (vs. baseline) increased the correspondence between self-reported positive affect and smiling. There was also an indication that high power (vs. baseline) bolstered the association between self-reported negative affect and frowning but the effect did not pass more stringent criteria for significance (p ≤ .005) and was therefore deemed inconclusive. The prediction that low power (vs. baseline) decreases the correspondence between self-reported affect and smiling and frowning facial expressions was not supported. Taken together, it would appear that (high) power can impact the relationship between self-reported affect and facial expressions, but it remains to be seen whether this effect extends beyond smiling facial expressions.

When sex is more than just sex: attachment orientations, sexual experience, and relationship quality

The authors explored the contribution of individual differences in attachment orientations to the experience of sexual intercourse and its association with relationship quality. In Study 1, 500 participants completed self-report scales of attachment orientations and sexual experience. The findings indicated that whereas attachment anxiety was associated with an ambivalent construal of sexual experience, attachment avoidance was associated with more aversive sexual feelings and cognitions. In Study 2, 41 couples reported on their attachment orientations and provided daily diary measures of sexual experiences and relationship interactions for a period of 42 days. Results showed that attachment anxiety amplified the effects of positive and negative sexual experiences on relationship interactions. In contrast, attachment avoidance inhibited the positive relational effect of having sex and the detrimental relational effects of negative sexual interactions. The authors discuss the possibility that attachment orientations are associated with different sex-related strategies and goals within romantic relationships.     

Automatic and controlled components of judgment and decision making

The categorization of inductive reasoning into largely automatic processes (heuristic reasoning) and controlled analytical processes (rule-based reasoning) put forward by dual-process approaches of judgment under uncertainty (e.g., K. E. Stanovich & R. F. West, 2000) has been primarily a matter of assumption with a scarcity of direct empirical findings supporting it. The present authors use the process dissociation procedure (L. L. Jacoby, 1991) to provide convergent evidence validating a dual-process perspective to judgment under uncertainty based on the independent contributions of heuristic and rule-based reasoning. Process dissociations based on experimental manipulation of variables were derived from the most relevant theoretical properties typically used to contrast the two forms of reasoning. These include processing goals (Experiment 1), cognitive resources (Experiment 2), priming (Experiment 3), and formal training (Experiment 4); the results consistently support the author's perspective. They conclude that judgment under uncertainty is neither an automatic nor a controlled process but that it reflects both processes, with each making independent contributions.     

The effect of category focus at encoding on category frequency estimation strategies

We investigated whether category focus at encoding affects how people estimate category frequencies. Participants in three experiments viewed items of various categories. They estimated category frequencies after categorizing them into relevant versus irrelevant categories (Experiments 1-2) or after categorizing versus memorizing them (Experiment 3). Verbal protocols (Experiments 2A and 2B), response latencies (Experiments 2A and 2B), frequency estimate changes (Experiment 2B), and the relationships between objective and estimated category frequencies and instance recall (Experiments 1-3) showed that the participants mainly used availability to estimate category frequencies after memorizing instances (Experiment 3) or after categorizing them into irrelevant categories (Experiments 1-2). After categorizing items into relevant categories, the participants relied more often on stored category frequency information (Experiments 1-3).
