Simulation à la Goldman: pretend and collapse

Theories of mind draw on processes that represent mental states and their computational connections; simulation, in addition, draws on processes that replicate (Heal 1986) a sequence of mental states. Moreover, mental simulation can be triggered by input from imagination instead of real perceptions. To avoid confusion between mental states concerning reality and those created in simulation, imagined contents must be quarantined. Goldman bypasses this problem by giving pretend states a special role to play in simulation (Goldman 2006). We argue that this path leads to the resurgence of the threat of collapse (Davies 1994), diluting the principled distinction between simulation and theory use. Exploration of a related method of real-mental states operating in a pretend mode leads to a factually untenable model. Our main goal here is to raise this problem as a challenge for Goldman’s reconfigured simulation theory. Only at the end we will briefly sketch a possible alternative way of quarantine that preserves the replicative element of simulation and avoids collapse. Figure 1 provides a guide to our argument.

Effects of received and mobilized support on recipients' and providers' self-efficacy beliefs: a 1-year follow-up study with patients receiving radical prostatectomy and their spouses

From a proactive agentic perspective, social support is not just seen as a protective cushion against environmental demands. Rather, support may facilitate an individual's self-regulation by enhancing perceived self-efficacy (i.e., enabling hypothesis). In the present study, patient-reported indicators of mobilized and received spousal support as predictors of their own and their spouses' self-efficacy beliefs were investigated within 1 year following radical prostatectomy. During this time frame, postoperative sequelae such as urinary incontinence and erectile dysfunctions are still likely to interfere with couples' everyday activities. Seventy-two patients receiving radical prostatectomy and their spouses participated. Patients' and spouses' self-efficacy beliefs and patients' received and mobilized spousal support were assessed prior to and 12 months following surgery. Additional patient-reported covariates at 1 year post-surgery were degree of bother by urinary incontinence, overall sexual satisfaction, and relationship satisfaction. Results indicated that patients' received spousal support was associated with higher levels of patients' self-efficacy only cross-sectionally, but not longitudinally. Support mobilized by the patient prior to and 1 year after surgery, however, positively predicted spouses' levels and changes in self-efficacy. Results, thus, did not fully confirm predictions by the enabling hypothesis of social support; rather, associated aspects, such as the degree of being mobilized as a provider of support or being needed, seem to enhance agency beliefs in spouses.     

Positive evidence for Eysenck’s arousal hypothesis: A combined EEG and MRI study with multiple measurement occasions

Eysenck’s arousal hypothesis suggests that introverts have greater cortical activity than extraverts. This prediction was tested in several studies that used the electroencephalogram (EEG) alpha activity to index cortical arousal, but empirical findings are inconsistent. Possibly, external factors of the measurement situation or static factors such as skull thickness may act as nuisance variables on alpha activity and thus mitigate the relation between arousal and extraversion. The aim of the present study was to test the arousal hypothesis with a focus on these methodological issues. Resting EEG was acquired on several occasions of measurement, skull thickness was quantified with anatomical magnetic resonance imaging (MRI), and extraversion was assessed by questionnaire. There was a positive association between alpha activity and extraversion, which was neither affected by external factors nor by skull thickness. This finding is in line with the arousal hypothesis and suggests that external or static factors do not contribute to the inconsistency of empirical findings.     

Speech‐perception‐in‐noise deficits in dyslexia

Speech perception deficits in developmental dyslexia were investigated in quiet and various noise conditions. Dyslexics exhibited clear speech perception deficits in noise but not in silence. Place‐of‐articulation was more affected than voicing or manner‐of‐articulation. Speech‐perception‐in‐noise deficits persisted when performance of dyslexics was compared to that of much younger children matched on reading age, underscoring the fundamental nature of speech‐perception‐in‐noise deficits. The deficits were not due to poor spectral or temporal resolution because dyslexics exhibited normal ‘masking release’ effects (i.e. better performance in fluctuating than in stationary noise). Moreover, speech‐perception‐in‐noise predicted significant unique variance in reading even after controlling for low‐level auditory, attentional, speech output, short‐term memory and phonological awareness processes. Finally, the presence of external noise did not seem to be a necessary condition for speech perception deficits to occur because similar deficits were obtained when speech was degraded by eliminating temporal fine‐structure cues without using external noise. In conclusion, the core deficit of dyslexics seems to be a lack of speech robustness in the presence of external or internal noise.     

Becoming the victim: Beyond sadism in serial sexual murderers

The behavior and characteristics of sexually sadistic serial murderers have been described primarily in relation to their paraphilic arousal to the control and torture of their victims. Sadistic sexual murderers who demonstrate both sadism and masochism have been described, but less is known about this type of offender. This article will review a number of hypotheses proposed to explain these behaviors. Next, the authors describe two cases demonstrating a separate phenomenon in which the offender assumes the identity of the victim that has been tortured to enhance his sexual gratification. It is proposed that these cases represent a grandiose form of sadism in which the offender extends his control of the victim beyond life and death. This form of sadism will be distinguished from sadomasochism, and its possible implications will be discussed.     

Process Dissociation Procedure: Double Dissociations Following Divided Attention and Speeded Responding

The validity of the process dissociation procedure was examined by manipulating attention and speed of responding in a recognition task. Both manipulations were expected to decrease the probability of controlled memory processes, c, while leaving the probability of automatic memory processes, a, unaffected. In order to estimate c and a, a multinomial processing tree modelwas fittedto the data.Contrary to expectation, a double dissociation (i.e.a decrease inc coupled with an increase in a) was obtained, suggesting that a does not accurately measure the probability of automatic processes. The results are discussed with reference to the independence assumption in the process dissociation procedure.     

How predictable is spelling? Developing and testing metrics of phoneme-grapheme contingency

Prior research has purported to show that words with infrequent phoneme-grapheme correspondences are more difficult to spell than words with frequent phoneme-grapheme correspondences. Defining exactly what a phoneme-grapheme relationship is, however, is not necessarily straightforward. There are a number of different assumptions that can be made. In this study, we developed four metrics of sound-spelling contingency based on all monosyllabic English words, including those with complex morphology. These metrics differed in the extent to which they included assumptions about spelling. The psychological reality of these different metrics was evaluated against data from a large-scale study of skilled adult spelling and a nonword spelling experiment. The results suggest that when spelling, people are sensitive to positional information, morphological status, vowel type, and a number of more idiosyncratic constraints.     

Stress Management in Bus Drivers: A Pilot Study Based on the Model of Effort–Reward Imbalance

A number of studies documented associations between work stress and elevated morbidity in professional drivers. The model of effort–reward imbalance (ERI) identifies distinct situational and personal characteristcs which elicit chronically stressful experience at work in terms of a mismatch between high costs and low gain. Fifty-four highly stressed male inner-city bus drivers (mean age 49,5 ± 5,3) were recruited to participate in a 12 weeks stress management program based on the ERI model (intervention group (IG) n = 26, control group (CG) n = 28). Intervention included relaxation, coping with anger and excessive work commitment (“high need for control”), management of conflicts with superiors, and recommendations for structural changes at work. After 12 weeks, mean level of “need for control,” a critical, health adverse style of coping with job demands, was significantly reduced in IG vs. CG, and this effect persisted after 3 months. In conclusion, a theory-based worksite stress management program in an occupational risk group is feasible and shows beneficial psychological effects.     

Verb frequency and enactment in implicit and explicit memory

In this article we report on two experiments concerning the effects of verb frequency and enactment on explicit- and implicit-memory tests. The results showed that verb frequency and enactment had additive effects on (explicit) recognition. Moreover, an (implicit) verb-identification test showed that prior enactment had absolutely no influence on this test, while verb frequency had a clear-cut effect. These results speak in favor of the assumption that verb-frequency and enactment effects are based on different types of information. It is further assumed that the verb-frequency effect is a lexical effect, whereas the enactment effect is not.     

Irrational Beliefs, Interpersonal Perception and Marital Adjustment

To test the hypothesis that the major evaluative beliefs postulated by Rational-Emotive Behaviour Therapy are related to marital adjustment, 50 married couples completed the Dyadic Adjustment Scale (DAS) and the Survey of Personal Beliefs (SPB). Significant correlations were found between DAS scores and three subscales (Other directed shoulds, Low frustration tolerance and Self worth) of the SPB. On the interpersonal dimension of assumed similarity, females in the high dyadic adjustment group were better able to predict their spouses' awfulizing, low frustration tolerance and self-worth beliefs than were females in the low adjustment group. However, the present study offers only limited support for the hypothesis that interpersonal perception of irrational evaluative beliefs is related to marital adjustment.
