ABSTRACT The present paper suggests a method to neutralize individual differences in skin conductance responsivity. suggested is standardization of the responses within individuals. This was compared range correction transformation previously. comparison based on data from two experiments which evaluated between electrodermal relevant and neutral stimuli information detection tasks. In first experiment used maximal response evoked by subject one regular presented task. second included...
The present study focused on gender differences in the tendency to omit items and guess multiple‐choice tests. It was hypothesized that males would show greater guessing tendencies than females use of formula scoring rather number correct answers result a relative advantage for females. Two samples were examined: ninth graders applicants Israeli universities. teenagers took battery five or six aptitude tests used place them various high schools, adults designed select candidates faculties...
The self-concept maintenance theory holds that many people will cheat in order to maximize self-profit, but only the extent they can do so while maintaining a positive self-concept. Mazar, Amir, and Ariely (2008, Experiment 1) gave participants an opportunity incentive on problem-solving task. Prior task, either recalled Ten Commandments (a moral reminder) or 10 books had read high school neutral task). Results were consistent with theory. When given cheat, moral-reminder priming task...
Abstract The Concealed Information Test (CIT) provides a valid tool for psychophysiological detection of concealed knowledge. However, its precise theoretical underpinnings remain matter debate. differential physiological responses elicited by concealed, relevant items, relative to control were traditionally explained as reflecting an orienting response (OR). According alternative account, these reflect attempts inhibit arousal. present study examined whether and what extent CIT efficiency...
The authors examined the incremental validity of reaction time (RT) measure beyond that skin conductance response (SCR) in detection concealed information.Participants performed a Stroop-like task which they named color critical and neutral words.Results show SCR highly differentiated between relevant words.However, RT demonstrated significant differentiation only when words denoted personally items (e.g., one's own name) not crime-relevant related to simulated crime.In both cases, combining...
This experiment was designed to examine the external validity of standard mock-crime procedure used extensively evaluate polygraph tests. The authors manipulated type (standard vs. a more realistic version) and time test (immediate delayed) examined their effects on Guilty Knowledge Test (GKT) recall rate relevant items. results indicated that only affected 2 outcome variables. associated with lower weaker detection efficiency than procedure. However, these were mediated by GKT questions...
Abstract This study examined the role of memory for crime details in detecting concealed information using electrodermal measure, Symptom Validity Test, and Number Guessing Test. Participants were randomly assigned to three groups: guilty, who committed a mock theft; informed‐innocents, exposed crime‐relevant items; uninformed‐innocents, had no information. tested immediately or 1 week later. Results showed (a) all tests detected guilty immediate condition, combining improved detection...
ABSTRACT The purpose of the present study is to test two predictions “Dichotomization Theory” on detection information. This theory relates differential autonomic responsivity in information task basic psychophysiological phenomena—the orienting response and its habituation. assumes that independent habituation processes take place typical experiment: relevant stimuli neutral stimuli, with a complete generalization within each stimulus category. It suggested this can explain results past...
Research interest in psychophysiological detection of deception has significantly increased since the September 11 terror attack USA. In particular, concealed information test (CIT), designed to detect memory traces that can connect suspects a certain crime, been extensively studied. this paper I will briefly review several paradigms have studied, with focus on CIT. The theoretical background CIT, its strength and weaknesses, potential applications as well research finings related validity...
Studies of attentional capture by personally significant stimuli have reached inconsistent results, possibly because improper control the participants' attention. In present study, authors controlled visual attention using a Stroop-like task. Participants responded to central color and ignored word presented either centrally (i.e., at focus attention) or peripherally outside attention). Central words led slower reaction times larger orienting responses for items than neutral items. These...
The effects of mental countermeasures on the efficiency psychophysiological detection with Guilty Knowledge Technique were examined in a mock-crime experiment 4 groups participants: innocent participants who not involved mock crime, guilty controls committed crime but received no countermeasure instructions, and instructions allowed to practice countermeasures. encouraged recall emotional situations from their past imagine themselves these during presentation irrelevant questions. Results...
Abstract The present study deals with the question of whether judgments made by experts working in familiar contexts are affected prior expectations and beliefs. Two experiments which were manipulated designed to determine what extent polygraph examiners their when analyzing interpreting charts. Prior examiners' charts did not include clear indications guilt or innocence, but objective physiological evidence included strong clearly contradicted examiner's expectations, these expectations....
A feature-matching model to account for the effects of novelty and significance on psychophysiological responsivity is presented. 2 experiments based a modified version Guilty Knowledge Technique were designed test predictions derived from proposed model. Results Experiment 1 demonstrated that electrodermal stimulus reflected degree which subjects habituated its components. provided additional support suggested additive. These findings hypothesis positively related match between input...
