A structural‐phenomenological typology of mind‐matter correlations

We present a typology of mind‐matter correlations embedded in a dual‐aspect monist framework as proposed by Pauli and Jung. They conjectured a picture in which the mental and the material arise as two complementary aspects of one underlying psychophysically neutral reality to which they cannot be reduced and to which direct empirical access is impossible. This picture suggests structural, persistent, reproducible mind‐matter correlations by splitting the underlying reality into aspects. In addition, it suggests induced, occasional, evasive mind‐matter correlations above and below, respectively, those stable baseline correlations. Two significant roles for the concept of meaning in this framework are elucidated. Finally, it is shown that the obtained typology is in perfect agreement with an empirically based classification of the phenomenology of mind‐matter correlations as observed in exceptional human experiences.     

The two sides of goal intentions: Intention self-concordance and intention strength as predictors of physical activity

Objective: The present research introduces an extended conceptualisation of self-concordance, which is considered an attribute not only of goals, but also of goal intentions. Based on a corresponding operationalisation, we investigate the interplay of both intention strength and intention self-concordance in the prediction of physical activity.

Design: Data were taken from a longitudinal study of 134 obese people who were asked to fill out a questionnaire three times every six months.

Main measures: Physical activity and intention self-concordance were measured by validated scales. Intentions strength was assessed by an item typically employed in the extant literature.

Results: Logistic regression analyses and path analyses showed both intention strength and self-concordance to be significant predictors of changes in physical activity over time. Additional analyses found self-efficacy to be a significant predictor of intention strength and self-concordance; for outcome expectations this was not the case.

Conclusions: Findings support the idea that intention strength and self-concordance are two critical facets of a goal intention that need to be considered in the prediction of physical activity participation. Whereas intention strength refers to the degree of determination with which a goal intention is adopted, self-concordance rather captures the quality of this intention.     

Personality correlates of party preference: The Big Five in five big European countries

The Big Five Model was used to assess the role of personality traits in orienting voting choice across five European countries (n = 1288). Findings from Italy, Spain, Germany, Greece, and Poland showed that the Big Five were linked to party preference in theoretically consistent ways. Traits had substantial effects on voting, whereas the socio-demographic characteristics of gender, age, income, and educational level had weaker influences. In each country, voters’ traits are seemingly congruent with the policies of their preferred party. The Openness trait has been shown to be the most generalizable predictor of party preference across the examined cultures. Conscientiousness was also a valid predictor, although its effect was less robust and replicable. Similarities and differences across countries were discussed and linked to the nature of the respective political discourses.     

Lipopolysaccharide-induced experimental immune activation does not impair memory functions in humans

Reconsolidation studies have led to the hypothesis that memory, when labile, would be modified in order to incorporate new information. This view has reinstated original propositions suggesting that short-term memory provides the organism with an opportunity to evaluate and rearrange information before storing it, since it is concurrent with the labile state of consolidation. The Chasmagnathus associative memory model is used here to test whether during consolidation it is possible to change some attribute of recently acquired memories. In addition, it is tested whether these changes in behavioral memory features can be explained as modifications on the consolidating memory trace or as a consequence of a new memory trace. We show that short-term memory is, unlike long-term memory, not context specific. During this short period after learning, behavioral memory can be updated in order to incorporate new contextual information. We found that, during this period, the cycloheximide retrograde amnesic effect can be reverted by a single trial in a new context. Finally, by means of memory sensitivity to cycloheximide during consolidation and reconsolidation, we show that the learning of a new context (CS) during this short-term memory period builds up a new memory trace that sustains the behavioral memory update.     

Children’s suggestion-induced omission errors are not caused by memory erasure

We explored whether children’s suggestion-induced omission errors are caused by memory erasure. Seventy-five children were instructed to remove three pieces of clothing from a puppet. Next, they were confronted with evidence falsely suggesting that one of the items had not been removed. During two subsequent interviews separated by one week, children had to report which pieces of clothing they had removed. Children who during both interviews failed to report that they had removed the pertinent item (i.e., omission error; n = 24) completed a choice reaction time task. In this task, they were presented with different clothing items. For each item, children had to indicate whether or not they had removed it. Significantly more errors were made for those removed items that children failed to report than for those they had not removed. This indicates that children’s suggestion-based omission errors are not due to erasure of memories.     

‘Of course I remember seeing that film’—how ambiguous questions generate crashing memories

Although previous research has shown that people are willing to report having seen non‐existent footages of high publicity events, no study has looked at the potential boundaries of what has been dubbed the crashing memory paradigm. We examined whether the ambiguity of interview questions may lead some people to affirm without much conviction having seen non‐existent footages. Using ambiguous, specific high‐suggestive, specific low‐suggestive, or neutral questions, the current study asked 120 individuals whether they had seen non‐existent footage of the assassination of the famous Dutch politician Pim Fortuyn. Replicating previous research, 63% of our participants in the ambiguous group falsely reported having seen the footage. This percentage dropped to 30% for the specific high‐suggestive as well as the specific low‐suggestive group, while still 27% of the neutral group were willing to make false reports. Our results demonstrate that crashing memories do depend on the way in which people are interviewed, but that question type does not fully account for these false reports.

Detection of Feigned Psychosis with the Structured Inventory of Malingered Symptomatology (SIMS): A Study of Coached and Uncoached Simulators

The aim of the present study was to investigate the efficacy of the Structured Inventory of Malingered Symptomatology (SIMS) to detect feigned psychosis in naïve, informed, and coached participants. Sixty undergraduate students were administered the SIMS and a number of filler questionnaires and asked to fill out the questionnaire honestly (controls; n = 15) or instructed to malinger psychosis because they were standing trial for a serious offense. Before they completed the SIMS, instructed malingerers either received no further information (naïve malingerers; n = 15), some information about psychotic symptoms (informed malingerers; n = 15), or some information about psychosis and a warning not to exaggerate symptoms (coached malingerers; n = 15). Even in the group of coached malingerers, the SIMS had acceptable sensitivity and specificity rates. These findings suggest that the SIMS may be of value in forensic assessments.     

A survey on adverse incidents in legal psychology studies: Reflections on ethics review

Ethics committees (ECs) regulate research activities to maintain research participants' autonomy and to protect them from harm and injury. No research to date attempted to establish how much risk is involved in social‐science research. Using a survey approach, we set out to estimate the risk of being involved in an incident for research participants in legal psychology and assessed researchers' views of ECs. Fifty‐nine of 188 respondents (31%) stated that they had experienced one or more incidents with a participant. The estimated risk of being involved in an incident was one to three per 10,000 participants, which according to biomedical standards defines a rare risk. Although some researchers were satisfied with their EC, the general tenor was one of discontent due to conservative decision‐making, lacking expertise, and overstepping demands. Whether ECs succeed in protecting participants from loss of autonomy, harm and injury are unknown but are open to empirical research.     

Severity of dysfluency correlates with basal ganglia activity in persistent developmental stuttering

Previous studies suggest that anatomical anomalies [Foundas, A. L., Bollich, A. M., Corey, D. M., Hurley, M., & Heilman, K. M. (2001). Anomalous anatomy of speech-language areas in adults with persistent developmental stuttering. Neurology, 57, 207-215; Foundas, A. L., Corey, D. M., Angeles, V., Bollich, A. M., Crabtree-Hartman, E., & Heilman, K. M. (2003). Atypical cerebral laterality in adults with persistent developmental stuttering. Neurology, 61, 1378-1385; Foundas, A. L., Bollich, A. M., Feldman, J., Corey, D. M., Hurley, M., & Lemen, L. C. et al., (2004). Aberrant auditory processing and atypical planum temporale in developmental stuttering. Neurology, 63, 1640-1646; Jancke, L., Hanggi, J., & Steinmetz, H. (2004). Morphological brain differences between adult stutterers and non-stutterers. BMC Neurology, 4, 23], in particular a reduction of the white matter anisotropy underlying the left sensorimotor cortex [Sommer, M., Koch, M. A., Paulus, W., Weiller, C., & Buchel, C. (2002). Disconnection of speech-relevant brain areas in persistent developmental stuttering. Lancet, 360, 380-383] could be at the origin of persistent developmental stuttering (PDS). Because neural connections between the motor cortex and basal ganglia are implicated in speech motor functions, PDS could also be associated with a dysfunction in basal ganglia activity [Alm, P. (2004). Stuttering and the basal ganglia circuits: a critical review of possible relations. Journal of Communication Disorders, 37, 325-369]. This fMRI study reports a correlation between severity of stuttering and activity in the basal ganglia and shows that this activity is modified by fluency shaping therapy through long-term therapy effects that reflect speech production improvement. A model of dysfunction in stuttering and possible repair modes is proposed that accommodates the data presented here and observations previously made by us and by others.
