A game-based formal system for Ł∞

A formal system for , based on a game-theoretic analysis of the ukasiewicz prepositional connectives, is defined and proved to be complete. An Herbrand theorem for the predicate calculus (a variant of some work of Mostowski) and some corollaries relating to its axiomatizability are proved. The predicate calculus with equality is also considered.     

Some experimental influences of lawyers' complicated questions on eyewitness confidence and accuracy

Eyewitness evidence and the confidence the eyewitness expresses in such evidence are crucial in many criminal trials. The present study is an examination of the influence of confusing questions often used by attorneys to examine witnesses in court. Participants viewed a videotaped incident and were questioned about the incident 1 week later. Half the participants were asked questions framed in a confusing form; the remaining half were asked the same questions in straightforward language. Confusing questions reduced the participant witnesses' accuracy and suppressed the confidence-accuracy relationships compared with the condition in which simple questions were asked. However, the number of absolutely sure responses was the same in both conditions, although these responses were almost always accurate in the simplified condition, whereas in the confusing question condition, accuracy was comparatively poor. This experiment demonstrates the importance of ensuring that lawyers ask witnesses simple, clear questions.     

Performance appraisal process and system facets: relationship with contextual performance

Because appraisal-related interactions between supervisors and employees may influence more than task performance, the authors considered the potential effects of social and interpersonal processes in performance appraisal on contextual performance. They hypothesized that performance appraisal process and system facets were associated with employees' contextual performance as well as with their perceptions of appraisal accuracy. After controlling relevant variables, they found that appraisal process facets explained variance in contextual performance and perceived accuracy beyond that accounted for by the system facets. However, when the order of entry for the process and system variable sets was reversed, only for perceived appraisal accuracy, as hypothesized, did the system facets account for variance beyond that explained by the appraisal process facets.     

The animating body: psychoid substance as a mutual experience of psychosomatic disorder

Starting from Jung's hypothesis of 'the psychoid', the author suggests that the concept can be extended and understood as a dynamic, relational and interpersonal experience-especially in regressed analytic relations. The author then defines his use of the term 'animating body' as having to do with primitive animal imagery and with psychosomatic symptoms stemming from disturbed pre-verbal and pre-whole-object stages of development. A case of a borderline patient is presented, whose projective identifications into the analyst infected him with her psychosomatic disorder, with her internalized Oedipal confusion and necessarily induced a mutually similar animal dream symbolism. If these embodied countertransference experiences (of desperate merging and sickening identification) can be lived through (tolerated and survived), thought through and interpreted, then they can actually become enlivening and lead to a therapeutic psychosomatic co-ordination.     

Dreading the pain of others? Altruistic responses to others' pain underestimate dread

A dislike of waiting for pain, aptly termed ‘dread’, is so great that people will increase pain to avoid delaying it. However, despite many accounts of altruistic responses to pain in others, no previous studies have tested whether people take delay into account when attempting to ameliorate others' pain. We examined the impact of delay in 2 experiments where participants (total N = 130) specified the intensity and delay of pain either for themselves or another person. Participants were willing to increase the experimental pain of another participant to avoid delaying it, indicative of dread, though did so to a lesser extent than was the case for their own pain. We observed a similar attenuation in dread when participants chose the timing of a hypothetical painful medical treatment for a close friend or relative, but no such attenuation when participants chose for a more distant acquaintance. A model in which altruism is biased to privilege pain intensity over the dread of pain parsimoniously accounts for these findings. We refer to this underestimation of others' dread as a ‘Dread Empathy Gap’.     

Electrophysiological measures of resting state functional connectivity and their relationship with working memory capacity in childhood

Functional connectivity is the statistical association of neuronal activity time courses across distinct brain regions, supporting specific cognitive processes. This coordination of activity is likely to be highly important for complex aspects of cognition, such as the communication of fluctuating task goals from higher‐order control regions to lower‐order, functionally specific regions. Some of these functional connections are identifiable even when relevant cognitive tasks are not being performed (i.e. at rest). We used magnetoencephalographic recordings projected into source space to demonstrate that resting state networks in childhood have electrophysiological underpinnings that are evident in the spontaneous fluctuations of oscillatory brain activity. Using the temporal structure of these oscillatory patterns we were able to identify a number of functional resting state networks analogous to those reported in the adult literature. In a second analysis we fused this dynamic temporal information with the spatial information from a functional magnetic resonance imaging analysis of functional connectivity, to demonstrate that inter‐subject variability in these electrophysiological measures of functional connectivity is correlated with individual differences in cognitive ability: the strength of connectivity between a fronto‐parietal network and lower‐level processing areas in inferior temporal cortex was associated with spatial working memory capacity, as measured outside the scanner with educationally relevant standardized assessments. This study represents the first exploration of the electrophysiological mechanisms underpinning resting state functional connectivity in source space in childhood, and the extent to which the strength of particular connections is associated with cognitive ability.     

Early Verb Learning: How Do Children Learn How to Compare Events?

An important problem verb learners must solve is how to extend verbs. Children could use cross-situational information to guide their extensions; however, comparing events is difficult. In 2 studies, researchers tested whether children benefit from initially seeing a pair of similar events (“progressive alignment”) while learning new verbs and whether this influence changes with age. In Study 1, 2.5- and 3.5-year-old children participated in an interactive task. Children who saw a pair of similar events and then varied events were able to extend verbs at test and differed from a control group; children who saw 2 pairs of varied events did not differ from the control group. In Study 2, events were presented on a monitor. Following the initial pair of events that varied by condition, a Tobii x120 eye tracker recorded 2.5-, 3.5-, and 4.5-year-olds’ fixations to specific elements of events (areas of interest) during the 2nd pair of events, which were the same across conditions. After seeing the pair of events that were highly similar, 2.5-year-olds showed significantly longer fixation durations to agents and to affected objects as compared with the all-varied condition. At test, 3.5-year-olds were able to extend the verb, but only in the progressive alignment condition. These results are important because they show children’s visual attention to relevant elements in dynamic events is influenced by their prior comparison experience, and they show that young children benefit from seeing similar events as they learn to compare events to each other.     

Job Type and Recruiters' Inferences of Applicant Personality Drawn from Resume Biodata: Their Relationships with Hiring Recommendations

Using data collected from 244 recruiters who reviewed resumes and made dispositional inferences and hiring recommendations for 122 entry‐level job applicants, we found that type of job opening (Holland's Conventional vs. Enterprising jobs) moderated relationships between recruiter inferences of applicant personality traits and recruiter judgments of applicant employability. Results showed Conscientiousness correlated with employability ratings for Conventional jobs (e.g., accounting) while extraversion was most associated with employability ratings for Enterprising jobs (e.g., marketing).     

Psychometric properties of Scheier and Carver's Life Orientation Test in a sample of Australian prisoners

The psychometric properties of Scheier and Carver's 1985 Life Orientation Test (LOT), which is a measure of optimism, were examined as part of a study of education, training, work experience, and expectations of sentenced adult prisoners in Western Australia. All prisoners at five metropolitan public prisons were invited to participate and 453 accepted. This represented a response rate overall of about 41%, with response rates at each of the individual prisons ranging from 13% to 90%. The average age of the prisoner sample was 34.4 yr. (SD = 10.2 yr.). The proportion of men in the sample was 79.7%. Mean sentence length was 66.9 mo. (58.5 for women and 69.2 for men), and the number of months of sentence remaining averaged 44.4 mo. (41.0 for women and 45.3 for men). Means and standard deviations of the LOT scores for prisoners were similar to those of other groups, and demographic differences between prisoners were not statistically significantly related to scores. The internal reliability of the LOT scores was acceptable. Confirmatory factor analyses indicated that the two-factor item-keying model fitted the prisoner data better than a one-factor model. However, the two factors did not simply reflect underlying optimism and pessimism constructs but were substantially affected by item keying.
