The miscommunication of deception: An adaptive perspective

Undergraduates were videotaped as they told lies and truths about their last job. Later, these undergraduates viewed the videotape and tried to guess which of their fellow subject were lying. Monetary incentives had been offered for successful lying and lie detection. Our subjects showed a “demeanor bias”—some looked honest even when they were lying; others looked dishonest even when they were telling the truth. These differences in apparent honesty were the primary determinant of deception judgments; perceivers' detection skills played a lesser role. Honest-looking subjects were predisposed to perceive others as dishonest. In general, our liars used hand gestures, maintained eye contact, and refrained from smiling. Perceivers misconstrued these behaviors as signs of honesty and could not often detect deceit—unless the lie was being told by a subject who had earlier told the truth. We draw on sociobiological concepts and offer an adaptive perspective on human deceit.     

Spiritual support in life threatening illness

This work evaluated the experiences of 45 patients of children with cancer and 101 cancer patients with their home pastors and hospital chaplains. The sttisfactions and difficulties enountered in these interactions are detailed, and recommendations are offered to aid persons in acute distress. Individuals in these circumstances appear to desire spiritual support more than evident psychologial aid, though the skillful use of the latter to understant the religious desires of the patients and parents is appreciated. It is also evident that pastors dealing which problems related to potential terminality are themselves under considerble stress.     

Differential acquisition rates for different types of information from pictures

In three picture-recognition experiments, we investigated the characteristics of “specific feature” and “holistic” information hypothesized to be extracted from pictures. In each experiment, exposure time was varied at study. The recognition test was two-alternative forced-choice in which the target/distractor relationship was manipulated in such a way that responding on the basis of one type of information or the other was required. The results indicated that following one fixation on a picture at the time of initial study, performance based on holistic information was superior to performance based on specific feature information, whereas the reverse was true following sufficient study time for multiple fixations. These results support a view of pictorial information acquisition which postulates that most holistic information extracted from a picture is extracted during the first eye fixation on the picture, whereas subsequent fixations have the primary purpose of seeking out specific, informative features.     

Anxiety and locus of conflict in emotionally disturbed children

The State Trait Anxiety Inventory for Children (STAIC) and the Children's Manifest Anxiety Scale (CMAS) were administered to 50 emotionally disturbed children (40 males and 10 females). In addition, ratings on a Locus of Conflict Rating Scale were obtained from their special education teachers. Significant correlations were obtained between all anxiety measures. However, anxiety, as measured by the CMAS, A State and A Trait, was not significantly correlated with the ratings of internalization, externalization, or the total maladjustment index. Girls reported greater anxiety than boys on the CMAS and the STAIC A Trait scale, while boys were rated as significantly higher on the internalization and externalization scales, and in total maladjustment.     

Some analyses of the verbal encoding deficit of alcoholic Korsakoff patients

Two experiments were designed to assess Korsakoff patients' ability to encode verbal information on the basis of its physical, nominal and semantic properties. The first investigation employed Wickens' release from proactive interference (PI) technique; a procedure that allows an assessment of a subject's ability to encode verbal information on the basis of its semantic properties. It was discovered that on tasks involving only a rudimentary verbal analysis, such as the ability to discriminate letters from numbers, the Korsakoff patients demonstrated a normal release from PI. However, on tasks that required a more sophisticated level of semantic encoding, such as those based on taxonomic class inclusion, the patients failed to show release from PI. The second investigation employed Posner's reaction time technique which assesses a subject's ability to encode the physical and nominal properties of simple verbal materials (letters). The results of this study showed that Korsakoff patients are impaired on even these rudimentary encoding tasks, which led to the proposal that Korsakoff patients' semantic encoding deficit might stem from an initial impairment in the speed at which physical and nominal properties of verbal information are analyzed.
