Sex and personality traits influence the difference between time taken to tell the truth or lie

A necessary component of lying is the withholding of a truthful response. Hence, lying may be conceptualised as involving the inhibition of an initial, automatic response (the truth) while an alternative response (the lie) is generated. We investigated response times to visually and auditorially presented questions probing recent episodic memory, when subjects answered questions truthfully or with lies. We also investigated whether the absolute response times or difference between time taken to tell the truth or lie was affected by participants' sex or correlated with personality scores on the Eysenck Personality Questionnaire Revised-Short Scale. 61 subjects answered the same 36 questions five times. The first time involved answering all questions truthfully, which allowed post hoc analysis of whether subjects had been consistent in their lying and truth-telling on the following four occasions. These latter four occasions involved answering all questions (one each with 'truth' or 'lie') for both types of presentation. Regardless of type of presentation or subjects' sex, subjects took approximately 200 msec. longer to lie than to tell the truth in response to each question (p<.001). There were significant correlations between truthful response times to auditorially presented questions and Eysenck 'Neuroticism' scores. There was also a significant correlation for women between mean individual lie-minus-truth time to auditorially presented questions and Eysenck 'Lie' scores. These preliminary data suggest that response time is systematically longer when telling a lie and that personality variables may play a part in this process.     

Assessing Organizational Behavior Models: A Comparison of Linear and Nonlinear Methods1

This study highlights the use of nonlinear statistic techniques in a behavioral model that incorporates dispositional and situational variables. When ordinary least squares and log-linear/logit results were compared, various unique associations were found between job satisfaction, job complexity, locus of control, and the number of available benefits. Overall, the findings prove that more nonlinear modeling is needed in the behavioral sciences.     

FURTHER ANALYSIS OF PROBLEM BEHAVIOR IN RESPONSE CLASS HIERARCHIES

A functional analysis identified the reinforcers for 3 participants' problem behavior, but only relatively mild problem behaviors (e.g., screaming, disruption) were observed when all topographies produced tested consequences. We then conducted an extinction analysis in which specific topographies produced a reinforcer while all other topographies were on extinction. The extinction analysis confirmed that the same reinforcer identified in the initial functional analysis maintained more severe topographies of problem behavior (e.g., aggression). In addition, results of the extinction analysis indicated that 2 of the participants displayed patterns of responding consistent with a response class hierarchy hypothesis, in which less severe problem behavior frequently occurred prior to more severe topographies. The 3rd participant displayed a response pattern indicative of differential reinforcement effects.     

TREATMENT OF MULTIPLY CONTROLLED PROBLEM BEHAVIOR

The aggressive behavior of a young boy with developmental delays occurred most frequently following a request to pick up his toys. The request ended a period of play and social interaction. This suggested the presence of multiple establishing operations. The initial treatment consisted of praise, a break, and access to the toys contingent on compliance. Results showed that aggression decreased only when we added social interaction to the break. Findings are discussed regarding treating multiply controlled problem behavior without extinction.     

Incompleteness and Disgust Predict Treatment Outcome in Pediatric Obsessive-Compulsive Disorder

Increasing evidence suggests that pediatric obsessive-compulsive disorder (OCD) is motivated not only by fear but also by feelings of incompleteness and disgust. However, it is currently unclear whether emotion involvement in OCD symptoms is associated with treatment response in youth with OCD. The present study examined whether treatment outcome for youth with OCD was predicted by the degree to which fear, disgust, and incompleteness were involved in baseline OCD symptoms. Children and adolescents with OCD entering treatment for this condition (N = 111) were administered standardized OCD symptom measures and an interview designed to assess the degree of fear, incompleteness, and disgust experienced during current OCD symptoms. Follow-up assessments occurred on average 13 months after baseline with each participant coded for outcome according to internationally acknowledged change criteria for pediatric OCD. Higher levels of incompleteness and disgust as part of baseline OCD symptoms predicted poorer outcome. The degree of fear during baseline OCD symptoms did not predict outcome. If replicated under controlled conditions, these results suggest that incompleteness and disgust may act as barriers to improvement in pediatric OCD and that treatment modifications that target these emotion-related motivators may improve outcome for a subset of youth.     

Cross-Lagged Relationships Between Insomnia and Posttraumatic Stress Disorder in Treatment-Receiving Veterans

Insomnia is a risk factor for the development of posttraumatic stress disorder (PTSD) while it is also plausible that PTSD symptoms can maintain insomnia symptoms. The present study examined longitudinal bidirectional relationships between insomnia and PTSD symptoms in treatment-seeking veterans. Participants were 693 ex-serving members of the Australian Defence Force who participated in an accredited, hospital-based outpatient PTSD program. Participants completed self-reported assessments of PTSD and insomnia symptoms at four time points: intake, discharge, 3-month, and 9-months posttreatment follow-up.Cross-lagged pathway analyses indicated significant bi-directional pathways between insomnia symptoms and PTSD symptoms at most time points. A final cross-lagged model between insomnia symptoms and the PTSD symptom clusters indicated that the PTSD symptom paths on insomnia symptoms, between intake and discharge, were attributable to reexperiencing PTSD symptoms. In contrast, across posttreatment follow-up time points there were significant paths of insomnia symptoms on all PTSD symptom clusters except from insomnia at 3-months to avoidance symptom at 9-months. PTSD symptoms and insomnia symptoms have bidirectional associations over time that may lead to the mutual maintenance or exacerbation of each condition following PTSD treatment. Where residual insomnia symptoms are present post-treatment, a sleep-focussed intervention is indicated and a sequenced approach to treatment recommended.
