An Impossibility Result for Coherence Rankings

If we receive information from multiple independent and partially reliable information sources, then whether we are justified to believe these information items is affected by how reliable the sources are, by how well the information coheres with our background beliefs and by how internally coherent the information is. We consider the following question. Is coherence a separable determinant of our degree of belief, i.e. is it the case that the more coherent the new information is, the more justified we are in believing the new information, ceteris paribus? We show that if we consider sets of information items of any size (Holism), and if we assume that there exists a coherence Ordering over such sets and that coherence is a function of the probability distribution over the propositions in such sets (Probabilism), then Separability fails to hold.     

Social and Temporal Comparisons Made by Individuals Living With HIV Disease: Relationships to Adherence Behavior1

When faced with the uncertainty of serious illness, individuals cope by comparing themselves to other people (social comparisons) and to other times in their lives (temporal comparisons). Participants were 44 individuals being treated for HIV who completed questionnaires measuring comparisons, adherence, and self‐efficacy; 34 also completed qualitative interviews that were coded for comparisons. High levels of comparison to worse‐off others, worse‐off past selves, and better‐off future selves were prevalent. Comparisons to worse‐off others resulting in positive affect were associated with greater medication adherence; comparisons to better‐off others resulting in negative affect were related to worse adherence. Self‐efficacy to adhere mediated the relationship between comparison and adherence. Individuals who are uncertain about treatment outcomes may engage in social comparison to gain specific knowledge about adherence.     

The no miracles argument without the base rate fallacy

According to an argument by Colin Howson, the no-miracles argument (NMA) is contingent on committing the base-rate fallacy and is therefore bound to fail. We demonstrate that Howson’s argument only applies to one of two versions of the NMA. The other version, which resembles the form in which the argument was initially presented by Putnam and Boyd, remains unaffected by his line of reasoning. We provide a formal reconstruction of that version of the NMA and show that it is valid. Finally, we demonstrate that the use of subjective priors is consistent with the realist implication of the NMA and show that a core worry with respect to the suggested form of the NMA can be dispelled.     

Entertainment as a Creature Comfort: Self-Control and Selection of Challenging Media

A between-subjects experiment examined selective exposure to films in an imagined self-control scenario, and if exposure would be systematically related to perceptions of the film content as challenging, enjoyable, and a should versus a want choice. Across 3 measures of selective exposure—using open-ended choice, closed-ended choice, and prospective ratings—participants in the depletion condition were less likely to select films that were cognitively challenging, affectively challenging, or a should choice. In contrast to nondepleted participants, depleted participants were more likely to select films they expected being fun, suspenseful, and less appreciated. These results provide support for the proposition that users’ momentary self-control capacity and their perception of challenge provided by content predict media choice.     

Identification With a Violent and Sadistic Aggressor: A Rorschach Study of Criminal Debt Collectors

This study examined personality functioning in a group of 27 incarcerated criminal debt collectors as assessed by the Rorschach Inkblot Method (RIM; Rorschach, 1921/1942) and the Psychopathy Checklist–Revised (PCL–R; Hare, 2003 Hare, R. D. (2003). Manual for the Hare Psychopathy Checklist–Revised (2nd ed.). Toronto, ON, Canada: Multi-Health Systems. [Google Scholar]). To explore whether these individuals represent a distinct subgroup within the violent offender population, we compared them to a group of incarcerated homicide offenders (n = 23) without a previous history of significant violence and a group who had committed less serious violent crimes (n = 21). Results revealed significantly more Rorschach indicators of past trauma (Trauma Content Index), aggressive urges (Aggressive Potential) and identification (Aggressive Content) among the debt collectors than the 2 other groups. In addition, debt collectors displayed significantly more interpersonal interest (Sum Human content), and significantly higher scores on the PCL–R. Our findings suggest that the debt collector might be viewed as a hostile variant of psychopathy.     

Incarcerated Violent Offenders' Ability to Avoid Revealing Their Potential for Violence on the Rorschach and the MMPI–2

Recently, Hartmann and Hartmann (2014) Hartmann, E., &; Hartmann, T. (2014): The impact of exposure to Internet-based information about the Rorschach and the MMPI–2 on psychiatric outpatients' ability to simulate mentally healthy test performance, Journal of Personality Assessment, 96, 432–444. doi:10.1080/00223891.2014.882342.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar] found that psychiatric outpatients, both with and without access to Internet-based information about the Rorschach Inkblot Method (RIM; Weiner, 2003 Weiner, I. B. (2003). Principles of Rorschach interpretations (2nd ed.). Mahwah, NJ: Erlbaum. [Google Scholar]) and the MMPI–2 (Butcher, Dahlstrom, Graham, Tellegen, &; Kaemmer, 1989 Butcher, J. N., Dahlstrom, W. G., Graham, J. R., Tellegen, A., &; Kaemmer, B. (1989). Manual for the Restandardized Minnesota Multiphasic Personality Inventory: MMPI–2. An administration and interpretive guide. Minneapolis: University of Minnesota Press. [Google Scholar]), were unable to imitate healthy test performance on these tests. We replicated the study by administering the RIM and the MMPI–2 to 63 incarcerated violent offenders using similar testing conditions. As in the previous study, comparisons were made not only among the 3 subgroups of incarcerated offenders, but also between these offender groups and the group of nonpatients examined in the previous study. On the RIM, Internet-coached and uncoached “faking good” offenders produced records with significantly higher F% and X–% and significantly lower M, m, SumC, X+%, P, AG, and COP than nonoffenders under standard instructions (effect sizes between d = 0.24 and d = 2.39). For AgC, AgPot, AgPast, and TCI% there were no significant differences between the faking offenders and the nonoffenders under standard instructions. On the MMPI–2 clinical scales, there were no significant differences between the faking good groups and the nonoffenders under standard instructions, except on Hs, Pd, and Sc. Both faking groups were identifiable by their high L scale scores. Although both faking groups managed to avoid giving responses with aggressive and generally psychopathological content on the RIM, they were unable to produce test profiles demonstrating healthy test performance on any of the tests; nevertheless, Internet-based test information might weaken test validity.     

Eye Movements Reveal Mental Looking Through Time

People often make use of a spatial “mental time line” to represent events in time. We investigated whether the eyes follow such a mental time line during online language comprehension of sentences that refer to the past, present, and future. Participants' eye movements were measured on a blank screen while they listened to these sentences. Saccade direction revealed that the future is mapped higher up in space than the past. Moreover, fewer saccades were made when two events are simultaneously taking place at the present moment compared to two events that are happening in different points in time. This is the first evidence that oculomotor correlates reflect mental looking along an abstract invisible time line during online language comprehension about time. Our results support the idea that observing eye movements is likely to “detect” invisible spatial scaffoldings which are involved in cognitively processing abstract meaning, even when the abstract meaning lacks an explicit spatial correlate. Theoretical implications of these findings are discussed.
