Language of lies in prison: linguistic classification of prisoners' truthful and deceptive natural language

Linguistic Inquiry and Word Count (LIWC) software was used to code truthful and deceptive words in prisoners' natural language. Reality Monitoring (RM) and Newman, Pennebaker, Berry, & Richards' (NP, 2003) models were used. NP indicates that lies contain fewer self‐references, other references, and exclusive words, and higher numbers of negative emotion and motion words. Higher sensory, spatial, temporal and affective RM terms were predicted for truths, and more cognitive mechanism words were predicted for lies. The RM model's hit rate was 71.1% and discriminability was 1.11 without spatial words, which were surprisingly higher in lies than in truth statements, and the NP model was 69.7%, d′ = 0.99. The software models were contrasted with humans' hit rates, and younger prisoners had 71% hits, d′ = 0.22, but older prisoners had 50% hits, d′ = 0.90. The software set unbiased criteria (β), but younger prisoners were biased in setting their criteria when judging statement veracity, β = ?0.34. Without other references, found to be higher in truths than in lies, NP classified 59% of statements correctly. Copyright © 2005 John Wiley & Sons, Ltd.     

A sad thumbs up: incongruent gestures and disrupted sensorimotor activity both slow processing of facial expressions

Recognising a facial expression is more difficult when the expresser's body conveys incongruent affect. Existing research has documented such interference for universally recognisable bodily expressions. However, it remains unknown whether learned, conventional gestures can interfere with facial expression processing. Study 1 participants (N?=?62) viewed videos of people simultaneously producing facial expressions and hand gestures and reported the valence of either the face or hand. Responses were slower and less accurate when the face-hand pairing was incongruent compared to congruent. We hypothesised that hand gestures might exert an even stronger influence on facial expression processing when other routes to understanding the meaning of a facial expression, such as with sensorimotor simulation, are disrupted. Participants in Study 2 (N?=?127) completed the same task, but the facial mobility of some participants was restricted, which disrupted face processing in prior work. The hand-face congruency effect from Study 1 was replicated. The facial mobility manipulation affected males only, and it did not moderate the congruency effect. The present work suggests the affective meaning of conventional gestures is processed automatically and can interfere with face perception, but does not suggest that perceivers rely more on gestures when sensorimotor face processing is disrupted.     

Introduction

In this introduction, the highlights of three papers addressing the questions of immigration, traumatic migration and exile are presented. The papers give clinical details of the work with persons inflight from dangerous and potentially fatal homeland situations, offer theoretical guidelines to thinking about the different implications of trauma upon refugees and migrating persons and families and also consider the particular demands on migration and exile in communities and families within the United States.     

Training intraverbal bidirectional naming to establish generalized equivalence class performances

The purpose of this study was to evaluate the effects of tact and intraverbal training on the establishment of generalized equivalence classes. Seventeen college students were exposed to tact training, listener testing, and intraverbal training (A'B’ and B'C’) in two experiments. Visual–visual matching‐to‐sample and intraverbal tests measured performances consistent with the formation of equivalence classes. Generalization was assessed with four novel sets of stimuli. In the second experiment, matching‐to‐sample tests for baseline relations (AB, BC) were eliminated to control for the possibility that equivalence classes were developed through exposure to these visual stimulus–stimulus relations. Thirteen of 17 participants passed all matching‐to‐sample and intraverbal posttests. Results suggest that when trained and emergent intraverbal relations were not maintained or were faulty, participants did not respond correctly during matching‐to‐sample posttests.     

Childhood Schizophrenia and Autism: An Empirical Study of Perceived Social Support

Although there is an abundance of literature focusing on social support for children and adults with mental illness, there is a paucity of research examining social support for individuals diagnosed with childhood and adolescent onset schizophrenia. Literature suggests that measuring social support in youth with schizophrenia poses unique challenges, which may be why it is so under-represented in existing research. In an effort to learn more about the availability of social support for children in this population, the current study compared measures of social support for children and adolescents, 5 to 17 years old, diagnosed with childhood schizophrenia to those for children diagnosed with autism spectrum disorder. The study surveyed parents of children with schizophrenia and autism using the Family Needs Questionnaire to measure perceived social support, and a subsection of the Ohio Youth Problem, Functioning, and Satisfaction Scales to measure the parent’s assessment of children’s level of functioning. A Family Questionnaire was also administered to collect demographic information about the children and their families. Results indicated, contrary to the original hypothesis, that parents of children with schizophrenia perceived their offspring as having more social support than children with autism, even though overall parents of children in the schizophrenia group rated their children as having a lower level of functioning. However, the study also found that when assessing the importance of social support needs, parents of children with schizophrenia rated their children’s needs as being significantly more important than parents of children with autism. A discussion of the research findings and limitations of the study are offered, in addition to suggestions for future research.
