Program evaluation and system change: Some issues and considerations

This paper explores some of the issues concerning the acceptance or rejection of positive program evaluation data by the system in which the program is embedded. System acceptance and diffusion rates are considered as functions of first- or second-order change factors. Several approaches to enhancing the probability of second-order change are presented and discussed.     

When logic fails: Implicit transitive inference in humans

Transitive inference (TI) in animals (e.g., choosing A over C on the basis of knowing that A is better than B and B is better than C) has been interpreted by some as reflecting a declarative logical inference process. We invert this anthropomorphic interpretation by providing evidence that humans can exhibit TI-like behavior on the basis of simpler associative mechanisms that underlie many theories of animal learning. In this study, human participants were trained on a five-pair TI problem (A+B-, B+C-, C+D-, D+E-, E+F-) and, unlike in previous human TI studies, were prevented from becoming explicitly aware of the logical hierarchy, so they could not employ logical reasoning. They were then tested with three problems: B versus D, B versus E, and C versus E. Participants only reliably chose B over E, whereas the other test conditions yielded chance performance. This result is inconsistent with the use of logical reasoning and is instead consistent with an account developed to explain earlier TI studies with rats that found the same pattern of results. In this account, choice performance is based on differential associative strengths across the stimulus items that develop over training, despite equal overt reinforcement.     

Reasonable accommodation for employees with mental disabilities: a mandate for effective supervision?

Reasonable accommodation under Title I of the Americans with Disabilities Act (ADA) for employees with mental disabilities is explored from a behavior analytic perspective. Although much of the attention in issues of reasonable accommodation is concentrated on persons with physical disabilities, it is argued that the needs of individuals with mental disabilities are in greater need of further study. The criteria for successful accommodation in the workplace for employees with mental disabilities is seen to be structurally different, but functionally similar to successful accommodations for employees with physical disabilities, and is based on the development of enabling environments. Behavior analysis offers a theoretical basis and performance management presents a methodological basis for analyzing, developing, implementing, and evaluating reasonable accommodation for persons with mental disabilities, largely in terms of effective supervision. It is concluded that Title I of the ADA may be seen as providing a mandate for effective supervision, which may also be extended to all employees.     

Cognitive vulnerability to depression: A comparison of the weakest link,keystone and additive models

Multiple theories of cognitive vulnerability to depression have been proposed, each focusing on different aspects of negative cognition and utilising different measures of risk. Various methods of integrating such multiple indices of risk have been examined in the literature, and each demonstrates some promise. Yet little is known about the interrelations among these methods, or their incremental validity in predicting changes in depression. The present study compared three integrative models of cognitive vulnerability: the additive, weakest link, and keystone models. Support was found for each model as predictive of depression over time, but only the weakest link model demonstrated incremental utility in predicting changes in depression over the other models. We also explore the correlation between these models and each model's unique contribution to predicting onset of depressive symptoms.     

Attitudes toward seeking professional psychological help among Chinese students at a UK university

Aim: In this study we aimed to investigate whether Chinese international and British home students at a university in the United Kingdom differed in their attitudes towards seeking psychological help. Method: The total sample comprised 323 participants. Participants completed measures to assess their attitudes toward seeking professional psychological help (recognition of need for psychological help, stigma tolerance, interpersonal openness, confidence in mental health practitioners). Results: Chinese students reported significantly less interpersonal openness than that reported by British students. Contrary to prediction, however, no significant group differences were found on any of the other mental health attitudes (i.e. recognition of need for psychological help, confidence in mental health practitioners or stigma tolerance). Within‐group contrasts also showed that Chinese students reported lower scores on interpersonal openness than on stigma tolerance and confidence in mental health practitioners. In contrast, British participants reported less confidence in mental health practitioners and recognition of the need for psychological help than reported for stigma tolerance and interpersonal openness. Conclusion: The findings highlight the need for a greater understanding of students' cultural inclinations toward mental health issues and cultural attitudes that may hinder and/or facilitate students' access and engagement with psychological services in higher education institutions.     

Microswitch technology and contingent stimulation to promote adaptive engagement in persons with minimally conscious state: a case evaluation

This study assessed whether a post-coma woman functioning at the lower end of the minimally conscious state would (a) develop adaptive responding through the use of microswitch technology and contingent stimulation, (b) consolidate and maintain her responding over time, and (c) show evidence of response-consequences awareness (learning and discrimination). The study involved an ABABB¹CB¹ sequence in which the A represented baseline phases, the B and B¹ intervention phases, and the C a control phase with continuous stimulation. Results indicated that the woman developed adaptive responding and consolidated it over the intervention phases of the study. The woman also showed evidence of being aware of response-consequences links. Potential implications and limitations of these findings are discussed.     

Later language development in narratives in children with perinatal stroke

Studies of young children with unilateral perinatal stroke (PS) have confirmed the plasticity of the developing brain for acquiring language. While recent studies of typically developing children have demonstrated the significant development of language well into adolescence, we know little regarding the course of language development in the PS group as they mature. Will children with PS continue to show the same remarkable plasticity that they exhibited at younger ages? In the present paper we investigate later language and discourse in children with perinatal stroke (ages 7–16) using spoken personal narrative as the discourse context. In contrast to the findings of the discourse studies of younger children with PS, children with left hemisphere lesions made more morphological errors, used less complex syntax and fewer syntactic types than controls; they also produced more impoverished story settings. In contrast, those with right hemisphere lesions performed comparably to controls, except in their impoverished use of complex syntax. The findings provide insight into the nature of later spoken language development in these children, revealing both the nature and extent of neuroplasticity for language as well as potential regional biases.     

Gender-Role Differences in Spatial Ability: A Meta-Analytic Review

Although gender-related differences in highly gender typed cognitive abilities are of considerable interest to educators and cognitive researchers alike, relatively little progress has been made in understanding the psychological processes that lead to them. Nash (1979) proposed a gender-role mediation hypothesis for such differences, with particular emphasis on spatial ability. However, changes in gender equality and gender stereotypes in the decades since merit a re-examination of whether a gender-role association still holds (Feingold 1988). A meta-analysis of 12 studies that examined gender-role identity and mental rotation performance was conducted. These included studies from the United Kingdom, Canada, Poland, Croatia, and the United States of America. The mean effect size for masculinity was r = .30 for men and r = .23 for women; no association was found between femininity and mental rotation. This effect size was slightly larger than that found previously by Signorella and Jamison (1986), and exceeds many other factors known to influence spatial ability. The implications of gender-role mediation of gender differences are discussed and future research directions are identified.     

Self-insight,Other-insight,and Their Relation to Interpersonal Conflict

The pessimistic conclusion that people have relatively poor insight into the weighting schemes they use when they make holistic judgements has been generally accepted among judgement researchers (e.g. Arkes, 1981; Balke, Hammond, & Meyer, 1973, Brehmer, 1984). The empirical research that supported this generalisation rested on indices of self-insight that were produced directly by the subjects. It was often the case that subjects were unable to correctly name even the single most important factor influencing their decisions, as indicated by a mathematical model of their judgement schemes. Using an alternate method of assessing self-insight, however, Reilly and Doherty (1989, 1992) found that subjects have far better self-insight than previously believed possible. The present paper employed the same methodology to investigate insight into the policy of another person as well as into oneself, and examined the relation of self-insight and other-insight to interpersonal conflict. Subjects were 50 dyads of university students. The results showed that: (1) subjects exhibited the expected high levels of self-insight via the recognition procedure; (2) subjects were able to identify the statistically generated policy of their roommate, thus exhibiting other-insight; (3) the ability to identify one's own policy is somewhat related to the ability to articulate one's own policy— that is, roommates with insight via recognition had higher indices of self-insight as measured by the traditional correlation method; (4) subjects who were able to identify their own policy were more likely to identify their roommate's policy and (5) individuals who possess self- and other-insight had less conflict in their roommate relationships.
