Separation—Individuation,Self-Concept,and Object Relations in Fraternal Twins,Identical Twins,and Singletons

Identical twins, fraternal twins, and singletons (n = 30 in each group) were compared on objective measures of separation–individuation, object relations, and self-esteem. No significant differences were found. The data did not support the popular notion that twins face special problems with respect to personality development or the idea that twins have more difficulty than others in establishing and maintaining close relationships. Twins and nontwins did not differ significantly with respect to marital status, number of years married, whether married before, number of previous marriages, number of years divorced, or living arrangements if single. The majority of twins had been raised in a way that encouraged at least some individual differences.     

Drawing what lies ahead: False intentions are more abstractly depicted than true intentions

The aim of this study was to examine how people mentally represent and depict true and false statements about claimed future actions—so‐called true and false intentions. On the basis of construal level theory, which proposes that subjectively unlikely events are more abstractly represented than likely ones, we hypothesized that false intentions should be represented at a more abstract level than true intentions. Fifty‐six hand drawings, produced by participants to describe mental images accompanying either true or false intentions, were rated on level of abstractness by a second set of participants (N = 117) blind to the veracity of the intentions. As predicted, drawings of false intentions were rated as more abstract than drawings of true intentions. This result advances the use of drawing‐based deception detection techniques to the field of true and false intentions and highlights the potential for abstractness as a novel cue to deceit.     

Automated verbal credibility assessment of intentions: The model statement technique and predictive modeling

Recently, verbal credibility assessment has been extended to the detection of deceptive intentions, the use of a model statement, and predictive modeling. The current investigation combines these 3 elements to detect deceptive intentions on a large scale. Participants read a model statement and wrote a truthful or deceptive statement about their planned weekend activities (Experiment 1). With the use of linguistic features for machine learning, more than 80% of the participants were classified correctly. Exploratory analyses suggested that liars included more person and location references than truth‐tellers. Experiment 2 examined whether these findings replicated on independent‐sample data. The classification accuracies remained well above chance level but dropped to 63%. Experiment 2 corroborated the finding that liars' statements are richer in location and person references than truth‐tellers' statements. Together, these findings suggest that liars may over‐prepare their statements. Predictive modeling shows promise as an automated veracity assessment approach but needs validation on independent data.     

Using unexpected questions to elicit information and cues to deceit in interpreter‐based interviews

We examined whether speech‐related differences between truth tellers and liars are more profound when answering unexpected questions than when answering expected questions. We also examined whether the presence of an interpreter affected these results. In the experiment, 204 participants from the United States (Hispanic participants only), Russia, and the Republic of Korea were interviewed in their native language by a native‐speaking interviewer or by a British interviewer through an interpreter. Truth tellers discussed a trip that they had made during the last 12 months; liars fabricated a story about such a trip. The key dependent variables were the amount of information provided and the proportion of all statements that were complications. The proportion of complications distinguished truth tellers from liars better when answering unexpected than expected questions, but only in interpreter‐absent interviews. The number of details provided did not differ between truth tellers and liars or between interpreter‐absent and interpreter‐present interviews.     

Assessing the Truthfulness of Witness Statements Made by Children (Aged 7--8, 10--11, and 13--14) Employing Scales Derived from Johnson and Raye's Model of Reality Monitoring

The goal of this study was to determine whether children's true and false witness statements could be differentiated using the model of reality monitoring. The effects of age and verbal ability on scales based on the model were also investigated. Children (N = 68) from three different age-groups (7--8, 10--11, and 13--14 years) made both a true and a false statement concerning a mildly traumatic event. The statements were analysed using the Revised Memory Characteristics Questionnaire. The vocabulary sub-scale of the WISC-R was also administered. True statements were found to contain more sensory information and expressions of time, and less affective information. Overall, 64% of the statements were correctly classified on the basis of the scales. Older children received higher scores on most of the reality monitoring scales compared to the youngest children regardless of the truthfulness of their statements. Furthermore, the verbal ability of the children was positively associated with scores on several of the scales. The classification accuracy suggests that the model should not be applied to individual cases of child testimony. Although the final decision concerning the usefulness of the scales should be based on ecologically valid field studies.

The source of the truth bias: Heuristic processing?

People believe others are telling the truth more often than they actually are; this is called the truth bias. Surprisingly, when a speaker is judged at multiple points across their statement the truth bias declines. Previous claims argue this is evidence of a shift from (biased) heuristic processing to (reasoned) analytical processing. In four experiments we contrast the heuristic‐analytic model (HAM) with alternative accounts. In Experiment 1, the decrease in truth responding was not the result of speakers appearing more deceptive, but was instead attributable to the rater's processing style. Yet contrary to HAMs, across three experiments we found the decline in bias was not related to the amount of processing time available (Experiments 1–3) or the communication channel (Experiment 2). In Experiment 4 we found support for a new account: that the bias reflects whether raters perceive the statement to be internally consistent.     

A First Step Toward Cognitive Remediation of Voices: a Case Study

Several studies have shown that source‐monitoring errors are related to verbal hallucinations in schizophrenia. An exploratory pilot study has been carried out to investigate the possibility of training patients in how to avoid errors in source‐monitoring. One patient with paranoid schizophrenia and persistent thought insertions was trained for 6?hours to use mnemonic techniques to compensate specific deficits in source‐monitoring. Results show that the patient was able to improve his performance and maintain the acquired progress at a 1‐month follow‐up assessment. These preliminary results are interesting for developing a larger controlled study of cognitive remediation of source‐monitoring deficits.
