Myths and realities of computerphobia: A meta-analysis

Abstract

Common beliefs about computerphobia were examined using meta-analytic techniques. Stringent screening criteria yielded 81 research reports with sample populations including college students, adults and business professionals, elementary/secondary students and teachers as well as postsecondary teachers. Results indicated that none of the six common beliefs characterizing the computerphobic represent reality. The computerphobic is equally likely to be a younger or older male or female. Although computerphobics tend to experience other types of anxiety (mathematics, test, state, trait), these anxieties account for little variance. Results indicated further that computer experience alone is not sufficient to eliminate computerphobia, but that psychological techniques have treated successfully these negative psychological reactions.     

Screening People With Anxiety/Depression for Suitability for Guided Self‐help

The aim of this study was to test a questionnaire for screening people with anxiety/depression for their suitability for certain forms of computer‐guided self‐help. A total of 196 referrals completed the screening questionnaire. Three clinicians each independently judged the referrals' broad problem type and suitability. Referrals were randomized to 1 of 3 clinicians for a screening interview. The results show that inter‐clinician agreement was good for questionnaire‐based problem type and suitability, and excellent for screening interview‐based problem type and suitability. Agreement between the questionnaire and interview was good on problem type but poor on suitability. Compared with the screening interview, the questionnaire detected suitable patients well but unsuitable patients less well. In conclusion, by quickly scanning the completed questionnaire, clinicians were able sensitively to detect patients' problem types that were suitable for certain forms of self‐help. Some unsuitability items need refining.     

Base-rate neglect as a function of base rates in probabilistic contingency learning

When humans predict criterion events based on probabilistic predictors, they often lend excessive weight to the predictor and insufficient weight to the base rate of the criterion event. In an operant analysis, using a matching-to-sample paradigm, Goodie and Fantino (1996) showed that humans exhibit base-rate neglect when predictors are associated with criterion events through physical similarity. In partial replications of their studies, we demonstrated similar effects when the predictors resembled the criterion events in terms of similarly skewed base rates. Participants' predictions were biased toward the more (or less) frequent criterion event following the more (or less) frequent predictor. This finding adds to the growing evidence for pseudocontingencies (Fiedler & Freytag, 2004), a framework that stresses base-rate influences on contingency learning.

Computer- and internet-based psychotherapy interventions

Computers and Internet-based programs have great potential to make psychological assessment and treatment more cost-effective. Computer-assisted therapy appears to be as effective as face-to-face treatment for treating anxiety disorders and depression. Internet support groups also may be effective and have advantages over face-to-face therapy. However, research on this approach remains meager.     

Laboratory of functional neuroelectrical imaging and brain–computer interfacing at Fondazione Santa Lucia

The laboratory of functional neuroelectrical imaging and brain–computer interfacing at Fondazione Santa Lucia is based on the joint work of researchers with a bioengineering and clinical neurophysiology background. The activity is mainly devoted to two aims: the non-invasive investigation of the motor cortical function under physiological and pathological conditions, through the development of advanced processing methods of the electroencephalographic signals; the development of a real-time EEG-based brain–computer interface (BCI) and the study of its use as an aid to enhance (or even to allow) the functional independence of persons with different degrees of motor disability.     

Evaluating Merger and Intersection of Equivalence Classes with One Member in Common

Sidman (1994) noted that the existence of a member that is common to more than one class may produce either class merger (union) or class intersection. A multiple-selection, matching-to-sample test was developed to examine the conditions under which these outcomes occur. Test trials each required three conditional discriminations involving selection or rejection of comparison stimuli under control of samples representing two categories. Test results obtained from an initial group of typical adults using familiar stimuli (DOG and BIRD, pictures of dogs and birds and relevant printed breed names (e.g., DALMATIAN, RETRIEVER) showed the conditional stimulus control best described as intersection. For example, the word DALMATIAN provided the context for selecting the dalmatian but not the retriever picture. However, these results may have depended on the participants'' verbal history as English speakers. Would conditional-discrimination training with overlapping sets of laboratory-generated stimuli also result in intersection? Naïve typical adults were assigned to one of three different training conditions. Like the participants tested with familiar stimuli, these participants demonstrated highly reliable test outcomes best described as showing class intersection, regardless of training condition. These findings begin to elucidate the necessary and sufficient conditions for establishing complex category-like classes of stimuli.     

Correlates and stability of alternate stimuli in a computer-based measure of inspection time

Inspection time tasks assess the ability to make a simple visual discrimination, typically in milliseconds. Typically, IT stimuli consists of a pi-shaped figure, in which subjects select the side with the significantly longer leg. To prevent storage in iconic memory, a backward mask is then introduced. However, some participants have reported that the mask may cause the shorter leg to appear to lengthen, creating a possible strategy that facilitates performance. As a result, alternative stimuli/masks have been developed; however, these alternative stimuli may be processed differently. This study assessed the cognitive correlates and stability of an alternative stimuli/mask. Results indicated that processing of the stimuli was influenced by an interaction between the complexity of the stimuli and the number of times it was presented. Specifically, the alternative stimulus/mask produced slower processing, particularly at the time of a second administration; however, it contributed an important and unique relationship with speeded, general intelligence.     

Philosophy for Computers: Some Explorations in Philosophical Modeling

Philosophical modeling has a long and distinguished history, but the computer offers new and powerful prospects for the creation and manipulation of models. It seems inevitable that the computer will become a major tool in future philosophical research. Here I offer an overview of explorations in philosophical computer modeling that we in the Group for Logic and Formal Semantics at SUNY Stony Brook have undertaken: explorations regarding (1) the potential emergence of cooperation in a society of egoists, (2) self-reference and paradox in fuzzy logic, (3) a fractal approach to formal systems, and (4) on-going explorations with models for the emergence of communication. The attempt is not to give a detailed report on any of these but to give a bird s-eye view of them all, emphasizing the general form that the models take, the philosophical motivations behind them, and the kinds of philosophical results that they may have to offer.
