Instructional effects on performance in a matching-to-sample study

Conducting studies using an undergraduate participant pool is fraught with difficulties. Among them are problems with adequately motivating subjects both to come to the study, and once there, to actively engage the experimental task. Thirty-one college students participated in a matching-to-sample (MTS) study involving substantial training, testing, retraining, and retesting of conditional discriminations and equivalence relations among four 4-member classes of nonsensical words. The study was conducted during the end of the semester, when performance often had been observed to be poorer than at other points in the semester. Eleven of the participants, in addition to standard instructions about the task, received additional instructions specifying molar consequences for high rates of "correct" responses throughout the procedure. This subset of participants displayed markedly improved performance as compared to those who did not receive the additional instructions. Results suggest that specification of molar contingencies improves participants' sensitivity to molecular contingencies within the study. Instructions that specify and increase the consequential functions of feedback provided during MTS trials may be one means of reducing unwanted variability in human MTS performance.     

Body Objectification and “Fat Talk”: Effects on Emotion,Motivation, and Cognitive Performance

To evaluate the effects of self-objectification on mood, motivation, and cognitive performance, 80 women either tried on a swimsuit (high objectification) or a sweater (low objectification). In addition, in order to investigate whether “fat talk” exacerbates the negative effects of self-objectification, half of each group overheard a confederate make self-disparaging body comments or neutral comments. Self-objectification, either as an individual difference disposition (trait) or as a situationally induced state, was associated with increased negative feelings, decreased intrinsic motivation, lower self-efficacy, and diminished cognitive functioning. The “fat talk” prime had mixed effects; potential reasons are discussed in detail. Exposure to fat talk was associated with an increase in negative emotion for women in sweaters, but a decrease in negative emotion for women in swimsuits. Fat talk was also associated with improved motivation and cognitive functioning for women low in trait self-objectification but diminished motivation and performance for women high in trait self-objectification.     

Must All be Saved? A Kierkegaardian Response to Theological Universalism

In this paper, I consider how a Kierkegaardian could respond critically to the question of strong theological universalism, i.e., the belief that all individuals must eventually be reconciled to God and experience everlasting happiness. A Kierkegaardian would likely reject what Thomas Talbott has called “conservative theism,” but has the resources to mount a sustained attack on the view that all individuals must experience everlasting happiness. Some have seen that Kierkegaard has some potential in this regard, but a full Kierkegaardian response to strong theological universalism has yet to be given. In this paper, I give such an account. That God could create beings free over against himself is the cross which philosophy could not bear but upon which it has remained hanging. – Kierkegaard     

Metamemory and reality monitoring

Metamemory judgements and reality monitoring judgements were compared for real and imagined stimuli. Line drawings of everyday items were either perceived or imagined in differing ratios, to (a) investigate people's ability to predict the class of item that would be better recalled (Judgements of Learning, JOL), and the class of item which would be better sourced (Judgements of Source, JOS) in a future recall test, and (b) test the hypothesis that participants would show a bias towards calling remembered items real when the source had been forgotten. Although participants' JOLs indicated that they believed real items would be more memorable than imagined, in both experiments a larger proportion of items from either class (real or imagined) was only recalled when presentation modality was less frequent for that class. By contrast, JOSs were no different for real or imagined items, even though source attribution was more accurate for real than imagined items. An attribution of memories to real rather than to imagined events that often occurs when participants are unsure about the source (labelled a ‘bias towards the real’) was due to phenomenological qualities of the memories. The results are discussed in terms of Johnson and Raye's ( 1981 ) reality‐monitoring model. Copyright © 2002 John Wiley & Sons, Ltd.     

Attention and executive function deficits in adolescent sex offenders.

Thirty male adolescent sex offenders and 20 age-matched male adolescents completed an extensive battery of attention and executive function tests. Controls were obtained from adolescents from a socially and economically deprived background, typical of the offending group. The attention battery was based on Mirksy, Anthony, Duncan, Ahearn, and Kellam (1991) and the executive function battery on Kelly (2000a). Successful matching for IQ was not achieved and therefore ANCOVA comparisons were made between the groups, with IQ as the covariate. In attention a highly significant difference was found on the focus-execute factor and a significant difference on the shift factor. In executive function there was a highly significant difference only on the response speed factor. In all cases better abilities were demonstrated by the control group. The importance of thorough neuropsychological investigation in the clinical assessment of this forensic group is supported. The clinical implications of neuropsychological deficits in terms of risk assessment and clinical management are discussed.     

Antidepressant discontinuation in the context of cognitive behavioral treatment for panic disorder.

Cognitive behavioral treatment (CBT) has been shown to reduce risk for adverse reactions (e.g., rebound panic) following benzodiazepine taper for patients with panic disorder (PD). This study evaluated the effects of antidepressant discontinuation for patients with PD in the context of CBT. Patients with PD (n=21) on a stable dose of antidepressants completed a 12-week group CBT treatment and were randomly assigned to discontinue antidepressants during week 8 of the treatment. There were no statistically significant differences between groups at posttreatment or 6-month follow-up. Data indicate no apparent immediate or long-term adverse effects for antidepressant discontinuation for patients with PD receiving CBT.     

Seeking patterns in dream content: A systematic approach to word searches

This paper systematizes the word search potential of DreamBank.net (Domhoff and Schneider, 2008a, Domhoff and Schneider, 2008b) by formulating and testing a set of word strings that can be used as default analytic categories in future investigations. The word strings are applied to the 981 dream reports of college students gathered by Hall and Van de Castle (1966) and the 136 dream reports of an 80-year old male gathered by Bulkeley (2008a). The results show a basic compatibility with the frequencies identified by Hall and Van de Castle’s labor-intensive method of content analysis employing teams of human coders. These findings support the expanded use of word search technologies for the scientific study of dream content and its relation to forms of waking consciousness.
