A feasibility study of Acceptance and Commitment Therapy for emotional dysfunction following psychosis

The experience of psychosis can lead to depression, anxiety and fear. Acceptance and Commitment Therapy (ACT) facilitates individuals to accept difficult mental experiences and behave in ways that are consistent with personally held values. This study was a single (rater) blind pilot randomised controlled trial of ACT for emotional dysfunction following psychosis. Twenty-seven participants with psychosis were randomised to either: ten sessions of ACT plus treatment as usual (TAU) or TAU alone. The Hospital Anxiety and Depression Scale, Positive and Negative Syndrome Scale, Acceptance and Action Questionnaire, Kentucky Inventory of Mindfulness Skills and Working Alliance Inventory were used. Individuals were assessed at baseline and 3 months post-baseline. The individuals randomised to receive ACT found the intervention acceptable. A significantly greater proportion of the ACT group changed from being depressed at time of entry into the study to not being depressed at follow-up. The ACT group showed a significantly greater increase in mindfulness skills and reduction in negative symptoms. Results indicated that individuals randomised to ACT had significantly fewer crisis contacts over the study. Changes in mindfulness skills correlated positively with changes in depression. ACT appears to offer promise in reducing negative symptoms, depression and crisis contacts in psychosis.     

Feedforward, -backward,and neutral transparency measures for Grade 1 and Grade 2 Greek readers

In the present study, orthographic metrics for Greek children’s Grade 1 and Grade 2 reading materials were presented. Data for five transparency metrics—three of which being neither feedforward nor feedbackward— were presented and offered for use in the research of children’s reading and spelling acquisition. The analysis demonstrated the complex relationships between metrics and compared the results with those obtained for the English language. The structure of these metrics from a variety of corpus sizes was investigated, and we concluded that large corpus sizes do not necessarily make a substantial contribution to the value of such metrics when compared with smaller samples.     

Functional analyses and treatment of precursor behavior

Functional analysis has been demonstrated to be an effective method to identify environmental variables that maintain problem behavior. However, there are cases when conducting functional analyses of severe problem behavior may be contraindicated. The current study applied functional analysis procedures to a class of behavior that preceded severe problem behavior (precursor behavior) and evaluated treatments based on the outcomes of the functional analyses of precursor behavior. Responding for all participants was differentiated during the functional analyses, and individualized treatments eliminated precursor behavior. These results suggest that functional analysis of precursor behavior may offer an alternative, indirect method to assess the operant function of severe problem behavior.     

The Minority-Majority Conundrum in Northern Ireland: An Orange Order Perspective

Researchers have argued that, depending on the framing of the Northern Ireland conflict, each group could either be a minority or a majority relative to the other. This complicates macrosocial explanations of the conflict which make specific predictions on the basis of minority or majority positions. The present paper argues that this conundrum may have arisen from the inherent variability in microidentity processes that do not fit easily with macroexplanations. In this paper the rhetoric of relative group position is analysed in political speeches delivered by leading members of an influential Protestant institution in Northern Ireland. It is apparent that minority and majority claims are not fixed but are flexibly used to achieve local rhetorical goals. Furthermore, the speeches differ before and after the Good Friday Agreement, with a reactionary "hegemonic" Unionist position giving way to a "majority-rights power sharing" argument and a "pseudo-minority" status giving way to a "disempowered minority" argument. These results suggest a view of the Northern Ireland conflict as a struggle for "symbolic power," i.e., the ability to flexibly define the intergroup situation to the ingroup's advantage.     

Normative values on the marks and mathews fear questionnaire: A comparison as a function of age and sex

While the Marks and Mathews Fear Questionnaire (1979) has gained widespread use, little information on its psychometric characteristics has been reported. Thus, one purpose of this investigation was to provide normative information on this device. A second purpose was to examine differences in reported fears as a function of age and sex. Fear Questionnaires were administered to a large sample of high-school students, college students, and adults. Means and standard deviations on the Fear Questionnaire are reported for the various groups. Significant differences were found between groups, with college and high-school women reporting more fears than corresponding men, college and high-school women reporting more fears than adult women, and college men showing a trend toward more fears than other men.Portions of this paper were presented at the Annual Meeting of the Association for the Advancement of Behavior Therapy, November 1985, Houston, Texas.     

Predicting a changing taste: Do people know what they will like?

A distinction is made between decision utility, experienced utility, and predicted utility and an experiment is reported addressing people's ability to forecast experienced utility. Subjects in two experiments made predictions of their future liking for stimuli to which they were then exposed daily for one week. The stimuli were ice cream in a pilot study, plain yogurt in the main study, and short musical pieces in both studies. Decreased liking was the modal prediction, even when the true outcome was increased liking, or reduced dislike. There was substantial stability of tastes, but there were also substantial individual differences in the size and even the sign of changes in liking with repeated exposure. There was little or no correlation between the predictions of hedonic change that individuals made and the changes they actually experienced.     

Human patellar reflex and conditioned reflex compared electromyographically

Inspite of continued work on the stretch reflex and “voluntary” movement study of the conditioned stretch reflex declined early in this century. The present experiments surveyed seven classical conditioning regimens for the human rectus femoris EMG seen after a blow to the patellar tendon. It was possible to (1) rule out conditioning to a knee touch that occured together with the tap, (2) establish weak conditioned stimulus, Sc, control for a tape recorder click and subsequent fist clench that preceded the tap by variable elapsed times, and (3) establish strong Sc control for a tone that sounded an invariant 0.27 sec before the tap. There were large differences, however, in Sc power across subjects, as measured by amplitude, latency, and frequency of conditioned EMG activity that occured prior to tap or when the tap was omitted. Purely reflexive responses, especially later EMG segments, also varied in amplitude and frequency, to support a conclusion that numerous controlling stimuli added or competed from trial to trial. Further disclosure of Sc contributions, including those from movement-generated stimulation, is warranted, especially for behaviors whose rhythmic timings, as in locomotion, might favor Pavlovian conditioning.
